Mercedes-AMG is implementing electric exhaust gas turbochargers in its next vehicle generation. The turbocharger features an electronically controlled electric motor which drives the compressor wheel before the wheel takes over the exhaust gas flow. Electric exhaust gas turbocharger from Mercedes-AMG
The electric exhaust gas turbocharger was developed in partnership with Garrett Motion. The technology comes from Formula 1 and is intended to combine the benefits of a small turbocharger with fast response times that achieves relatively low peak performance and of a large turbocharger with high peak performance but delayed responses.
A slim electric motor measuring around 4 cm is integrated directly on the charger shaft between the turbine wheel on the exhaust side and the compressor wheel on the fresh-air side. The electronically controlled electric motor drives the compressor wheel before the wheel takes over the exhaust gas flow, which significantly improves responsiveness even at idle speeds and across the entire engine-speed range. The turbocharger is powered by a 48-volt on-board electrical system and can achieve speeds of up to 170,000 rpm, which enables a very high air flow rate. Along with the electric motor and power electronics, the turbocharger is connected to the combustion engine’s cooling circuit.

XC40 Recharge Pure Electric P8 available from £53,155
UK deliveries anticipated from early 2021
The Volvo XC40 Recharge Pure Electric – Volvo’s first all-electric car – is now available for UK customers to order.
The first of five fully electric cars to be launched by the Swedish company over the next five years, the XC40 Recharge Pure Electric P8 is capable of a travelling more than 249 miles on a single charge, and can be charged to 80% of its battery capacity in as little as 40 minutes using a fast charger. Being an electric car, it will deliver significant savings to owners in running costs, as well as tax benefits.
Inside, the car benefits from the company’s brand-new infotainment system powered by Google Android, as well as taking the XC40’s already renowned use of interior space even further.
Kristian Elvefors, Volvo Car UK’s Managing Director, said: “For Volvo Cars, the future is electric. The battery-powered XC40 spearheads our ambitious sustainability strategy, while bringing the huge benefits of electric driving – and more – to an already award-winning package.”
A milestone in one of the automotive industry’s boldest electrification strategies
Volvo’s first entrant into the compact premium SUV segment when it was launched in 2018, the XC40 has seen unprecedented success, winning a host of prestigious awards – including European Car of the Year in 2018 – and quickly becoming the firm’s best-selling model in the UK. The Recharge Pure Electric variant comes at the perfect time, with almost three quarters of consumers considering an all-electric car for their next purchase1.
The XC40 Recharge Pure Electric marks a major milestone in Volvo Cars’ electrification strategy, which is one of the boldest from any traditional car maker. As part of a long-term ambition to be climate-neutral by 2040, the company aims to reduce tailpipe emissions by 50% per car, and for half of all new vehicles it sells globally to be pure electric, by 2025.
The all-electric XC40 also expands Volvo’s already comprehensive range of plug-in vehicles, now sold under the Recharge brand, with customers already able to purchase a plug-in hybrid version of every model in the Volvo range.
While the recently launched plug-in hybrid XC40 is ideal for those making the transition to electric driving – its 28-mile electric range is backed up by a petrol engine for greater distances – the Pure Electric is the perfect car for those ready to commit to all-electric motoring. The average distance driven each day by UK motorists is 30 miles2, so its 249-plus-mile range more than covers most people’s daily requirements – especially if home or workplace charging is installed meaning a full charge at the start of each journey.
The XC40 P8’s long range does not come at the expense of performance, with its twin electric motors producing 408hp to deliver a 0-62mph time of only 4.9 seconds.
Interior design: making clever even cleverer
While the XC40 already follows the principle of doing more with less, the Recharge Pure Electric version takes this even further. The lack of an internal combustion engine frees up space for an additional 30-litre storage compartment or ‘frunk’ under the front bonnet, while the placement of the batteries under the centre of the car means space is not compromised elsewhere.
As with any other XC40, the battery-powered version comes equipped with clever interior touches such as a removable waste bin, a fold-out hook in the glove compartment for bags, and a useful boot divider complete with hooks for keeping shopping bags separate and upright. A pair of sizeable front door bins come courtesy of the traditionally door-housed speakers being moved to the base of the windscreen.
The interior of the battery-powered XC40 also carries over the strong focus on sustainability from other variants, with the door linings and carpets made from 97% recycled plastic bottles.
The all-electric XC40 marks the debut of Volvo Cars’ brand-new Android-powered infotainment system, which gives customers unprecedented personalisation increased intuitiveness and new embedded Google technologies and services.
Total integration of Android Automotive OS, Google’s open-source Android platform, means services such as Google Maps, Google Assistant and other automotive apps will be built in.
For the first time on a Volvo car, software and operating system updates will be available over the air, meaning an XC40 Recharge Pure Electric will improve over its lifetime rather than being at its peak on leaving the factory.
One of the safest cars on the road
In spite of the challenges presented by the lack of an internal combustion engine, the electric XC40 is one of the safest cars on the market. Volvo Cars’ safety engineers have totally redeveloped the frontal crash structure, while introducing a new and unique safety structure for the passengers and battery – helping to keep occupants as safe as they are in any other Volvo.
The fully electric XC40 SUV – Volvo’s first electric car and one of the safest on the road
The XC40 Recharge Pure Electric is also the first Volvo to feature a new version of Pilot Assist, the driver-assistance technology that deploys steering, acceleration and braking support to help take the strain during long motorway journeys and sitting in traffic. The system now uses Google Maps for information such as speed limits and curves in the road to improve its functionality.
A new Emergency Stop Assist function is now included, meaning that if the driver is not holding the steering wheel while Pilot Assist is activated, the driver will be warned in different stages until the vehicle is brought to a safe stop.
In the EU alone, the electronic stability program has saved some 15,000 lives.
Worldwide, 82 percent of all new passenger cars feature the anti-skid system.
Harald Kroeger: “The development of ESP® was a milestone on the path to our ‘vision zero’ of no more road deaths.”
Stuttgart, Germany – A wet road and a sudden evasive maneuver: there was a time when such a situation would frequently have ended in a ditch or against a crash barrier, and not rarely with fatalities or severe injuries. Almost 25 years ago to the day, a remedy was finally provided in the shape of a pioneering invention – the ESP® electronic stability program that Bosch and Daimler-Benz first launched in S-class vehicles in 1995. Since then, ESP® has been keeping vehicles safely on track, also in critical situations. Bosch accident researchers estimate that in the EU alone, the anti-skid system has saved some 15,000 lives over the past 25 years, as well as preventing just under half a million accidents involving personal injury. Together with the seatbelt and airbag, ESP® is one of the most important life-savers in a vehicle. “The development of the electronic stability program was a milestone on the path to our ‘vision zero’ of no more road deaths,” says the Bosch board of management member Harald Kroeger. “ESP® is an outstanding example of what we mean by ‘Invented for life.” The innovation may be from 1995, but there is nothing dated about it: Bosch has continuously improved its anti-skid system, and produced more than 250 million ESP® systems to date. Modern cars are inconceivable without this electronic guardian angel. Worldwide, 82 percent of all new vehicles are equipped with ESP®. In 2017, this figure was 64 percent.

ESP® can prevent up to 80 percent of all skidding accidents
Especially when roads are wet or icy, when evading unexpected obstacles such as animals on the road, and also when driving into a bend too fast, the electronic stability program intervenes. With ESP® on board, up to 80 percent of all skidding accidents can be prevented. It combines the functions of the ABS antilock braking system and the TCS traction control system, but can do considerably more. It also detects vehicle skidding movements, and actively counteracts them.
The anti-skid system uses information about vehicle dynamics to detect whether the car is heading in the direction the driver is steering. If there is a discrepancy between these two factors, ESP® intervenes. This may sound simple, but is in fact a complex process. Smart sensors help compare steering angle and vehicle trajectory 25 times a second. If the two diverge, ESP® reduces engine torque and brakes individual wheels. In this way, the system helps the driver prevent the vehicle from breaking away or skidding – effectively nipping many accidents in the bud.
Breakthrough following the elk test
The story behind this achievement is a long one. It started in the 1980s with initially independent efforts by Bosch and Daimler-Benz to achieve more vehicle stability. From 1992 until market launch, experts from the two companies worked together in a project unit. The legendary elk test of 1997 helped the system achieve a breakthrough: during tests for a Swedish automotive magazine, a Mercedes Benz A-class tipped over when making an abrupt evasive maneuver. Mercedes-Benz responded by making ESP® standard equipment. Since that time, more and more vehicles of many different automakers have adopted the anti-skid system.
Fewer accidents, fewer injuries, fewer fatalities – legislators have also recognized the benefits of ESP® and made it a mandatory feature of vehicles in many parts of the world. In the EU, the mandating process was gradual. From November 2011, it was initially mandatory for new passenger-car and commercial-vehicle types, and from November 1, 2014, for all newly registered passenger cars and commercial vehicles. And also in Argentina, Australia, Brazil, Canada, China, Ecuador, Israel, Japan, Malysia, New Zealand, Russia, South Korea, Turkey, and the United States, the anti-skid system is either legally mandated or a self-imposed commitment. Experience from Europe shows that if the proportion of vehicles featuring the system rises, accident numbers fall.
“ ESP® has taken road safety to a new level. ”
Bosch board of management member Harald Kroeger
Basis for automated driving
“ESP® has taken road safety to a new level,” Kroeger says. And it has done so across a diverse range of vehicle types. Bosch offers customized ESP® systems for all powertrain types, from combustion engines to electric motors, and for vehicles of all kinds, from micro cars to commercial vehicles. Even for motorized two-wheelers, the company has developed a kind of ESP®. The MSC motorcycle stability control that Bosch launched in 2013 ensures the best possible stability in all riding situations, and is a further pioneering road-safety achievement.
At the same time, ESP® is the basic technology for many driver assistance systems, as well as for the automated driving with which Bosch is pursuing its vision zero. “Whether new or tried and tested, Bosch technologies alert and support drivers in critical situations. And increasingly, they are in a position to assume monotonous and fatiguing tasks. This gives us an opportunity to further reduce the number of accidents and road deaths,” Kroeger says. Whether with or without a driver at the wheel, Bosch will be nipping accidents in the bud in the future as well.
Volvo Cars, a global leader in automotive safety, is setting new safety and technology standards by partnering with tech firm Luminar to provide their industry-leading LiDAR and perception technology for Volvo’s next generation cars.
The partnership will deliver Volvo’s first fully self-driving technology for highways and paves the way for future active safety developments.
Volvo Cars’ next generation SPA 2 modular vehicle architecture will be available as hardware-ready for autonomous drive from production start in 2022, with the Luminar LiDAR seamlessly integrated into the roof.
Cars based on SPA 2 will be updated with software over the air and if customers decide to opt for it, the Highway Pilot feature that enables fully autonomous highway driving will be activated once it is verified to be safe for individual geographic locations and conditions.
“Autonomous drive has the potential to be one of the most lifesaving technologies in history, if introduced responsibly and safely,” said Henrik Green, chief technology officer at Volvo Cars. “Providing our future cars with the vision they require to make safe decisions is an important step in that direction.”
In addition to the Highway Pilot feature, Volvo Cars and Luminar are also exploring LiDAR’s role in improving future advanced driver assistance systems (ADAS), with the potential for equipping all future SPA2-based cars with a LiDAR sensor as standard.
Luminar’s technology is based on its high performance LiDAR sensors, which emit millions of pulses of laser light to accurately detect where objects are by scanning the environment in 3D, creating a temporary, real-time map without requiring internet connectivity.
LiDAR is key in creating cars that can navigate safely in autonomous mode, providing them with the reliable vision and perception that cameras and radar alone cannot provide. LiDAR is the ideal basis for safe decision-making in complex environments at high speeds.
To enable the Highway Pilot feature, Luminar’s perception technology will be combined with autonomous drive software and the cameras, radars and back-up systems for functions such as steering, braking and battery power installed on forthcoming Volvo cars equipped for self-driving. Put together, this gives Volvo users who want it access to a safe, fully self-driving feature for use on highways.
“Soon, your Volvo will be able to drive autonomously on highways when the car determines it is safe to do so,” said Henrik Green. “At that point, your Volvo takes responsibility for the driving and you can relax, take your eyes off the road and your hands off the wheel. Over time, updates over the air will expand the areas in which the car can drive itself. For us, a safe introduction of autonomy is a gradual introduction.”
As part of the announcement, Volvo Cars and Luminar are deepening their collaboration to jointly ensure robust industrialisation and validation of Luminar’s LiDAR technology for series production. Volvo Cars has also signed an agreement to possibly increase its minority stake in Luminar.
For Silicon Valley-based Luminar, partnering with Volvo Cars represents the company’s first delivery of its technology into series production. This is a key step to achieving the economies of scale that are required to bring the technology to the wider automotive industry.
“Volvo is recognised as the pioneer of automotive safety, having driven standardisation across the industry for the most advanced life-saving technologies,” said Austin Russell, founder and CEO of Luminar. “The next era of safety lies within autonomous driving and once again, Volvo has taken the lead with a major industry milestone. We’ve solved the key cost, performance, and auto-grade challenges to make series production possible, and alongside Volvo are making the technology available to the world.”
How driverless shuttles get safely from A to B Project 3F presents its results on automated driving at low speed
On course: vehicles can continue driving in spite of altered circumstances along theroute and technical failures in the system
On board: people and goods transported on test grounds in Renningen and Aachen
As a team: six partners involved in the publicly funded project
Renningen, Germany – Ferrying visitors from tram stop to exhibition center, supplementing public transport routes, moving containers full of packages in a logistics center: all these are possible use cases for driverless shuttles. The main thing is for them to be able to get safely from A to B – safely in both senses: reliably and without danger. This is what Project 3F, “Driverless and fault-tolerant vehicles in the low-speed range,” set out to achieve, with a focus on fail-safe operation. “The aim was to develop solutions to ensure that automated shuttles can move around safely, even if a technical malfunction occurs or obstacles suddenly appear,” says Steffen Knoop, project leader in research and advance engineering at Robert Bosch GmbH.
Specifically, the project team was concerned with making sure that the system does not fail completely in the event of a fault, but rather that the vehicle can continue to drive. With 4.3 million euros in funding from the German Federal Ministry of Economic Affairs, the project featured Bosch as the consortium leader and involved three other companies, a university, and a research institute: StreetScooter GmbH, RA Consulting GmbH, the FZI Research Center for Information Technology, Finepower GmbH, and RWTH Aachen University.
Better safe than sorry: redundant power supply and sensor technology
“Driverless shuttle buses need to meet different requirements than, say, highly automated passenger cars,” explains Bosch project coordinator Thomas Schamm. To operate without (safety) drivers, shuttles must be able to monitor their system autonomously – in other words, perform diagnostic tasks – and cope with any technical faults detected so that they can continue driving. At the same time, they must be able to secure the system in the event of critical faults, for example by bringing themselves to a stop. Project 3F has been working on what the requirements look like in detail, how the systems must be designed on that basis, and how to optimize the way the individual components interact.
One solution is to build in redundancy, in other words to duplicate safety-relevant functions. For example, the researchers developed redundant systems for the power supply so that the electrical powertrain and vehicle electrical system are reliably protected. They also adapted and refined the sensor technology to suit the vehicle design. In order to reliably detect obstacles, they installed several lidar and radar sensors at various points around the vehicle, giving it the ability to observe its surroundings from different positions. By delivering a 360-degree birds-eye view and avoiding blind spots, this creates a kind of 3D protection zone. This setup not only detects obstacles on the road, such as barriers, it also spots things like hanging branches.
Detect, classify, adjust driving behavior.
Another solution is to build in fault tolerance, whereby the failure of a subsystem is at least partly compensated for by other functions. This is a bit like how it is with people: if the lights suddenly go out in a room, we use our other senses and feel our way around instead of becoming paralyzed. The shuttle behaves in a similar way: if it is blind in a certain area, say because leaves are stuck to the sensor or a large object such as a dumpster is completely blocking the view in one direction, it slows down or omits the parts of the route that can no longer be detected.
In addition, the project worked to ensure that shuttle buses can also react to altered circumstances along their defined route. The vehicles are programmed to slow down when any moving objects approach or, in case of doubt, to give unknown objects a wide berth. When they identify familiar landmarks such as streetlights, on the other hand, they resume their journey at full speed. If there is any imminent danger, the shuttle will come to a precautionary stop. The objective is for the vehicle to adapt its driving behavior to the circumstances in real time while also continuing on its journey automatically whenever possible, even in the event of system malfunctions or obstacles in its path.
Three times the telemetry, twice the usability
Data on the journey being undertaken and the current technical status can be transmitted from the vehicle and back to it. Information on three different functions is transmitted back and forth: diagnostics, monitoring, and control. So that is three times the telemetry, which is why we’re calling it “teletrimetry.” This lays the foundation for an entire fleet of automated shuttle buses to be remotely monitored, as well as repaired or even controlled, for instance to open the doors. It means the vehicles will get help if they do ever reach their fault-detection and compensation limits, or if they simply require scheduled maintenance.
The solutions developed in the project work not only for driverless shuttle buses. They can also provide robust support for logistics processes. Project members developed an assistance system for driver-vehicle interaction that enables highly accurate positioning of swap body lifting trucks – special vehicles for moving containers in logistics centers. The objective here was to move the vehicles with centimeter precision underneath gantry cranes to enable the swift removal of transport containers. This requires precise localization and a form of automated parking under the gantry. In practice, this automated maneuver enables error-free container collection and positioning.
These developments were tested on several test tracks: at Bosch’s research campus in Renningen, two shuttle buses trialed the transportation of people around a site shared with pedestrians; while at an innovation park near Aachen and in the area around a Deutsche Post/DHL depot, a logistics vehicle was deployed to test the interaction between driver and automated vehicle.

Powerful computing for the electronics architecture of the future – vehicle computers: Increasing electrification, automation, and connectivity are placing ever higher demands on vehicles’ electronics architecture. One key to the vehicles of the future lies in the new high-performance vehicle control units. Bosch vehicle computers will increase computing power in vehicles by a factor of 1,000 by the start of the next decade. The company is already producing these kinds of computers for automated driving, the powertrain, and the integration of infotainment systems and driver assistance functions.
Full power – services for electromobility: Bosch’s Battery in the Cloud prolongs the life of batteries in electric cars. Smart software functions analyze the status of the battery based on real-time data from the vehicle and its surroundings. It recognizes stress factors for the battery, such as high-speed charging. On the basis of the data collected, the software then calculates measures to counter cell aging, such as optimized recharging processes that mean less wear and tear for the battery. Convenience Charging, Bosch’s integrated recharging and navigation solution, allows for a precise range forecast, route planning that includes recharging stops, and convenient recharging and payment.
E-mobility for the long haul – fuel-cell system: Mobile fuel cells offer long ranges, short refueling times, and – with hydrogen produced using renewable energy – emissions-free vehicle operation. Bosch plans to commercialize a fuel-cell stack that it has refined together with the Swedish company Powercell. In addition to the stack, which converts hydrogen and oxygen into electrical energy, Bosch is developing all the essential fuel-cell system components to a production-ready stage.
Connected products that save lives – Help Connect: Someone who has had an accident needs help fast – regardless of whether they are at home, on a bicycle, doing sports, in a car, or on a motorcycle. For these and any other emergency situations, Bosch offers a guardian angel in the form of Help Connect. Available as a smartphone app, this connectivity solution transmits lifesaving information to emergency services via Bosch service centers. The solution requires automated accident detection, for instance via the smartphone sensors or the vehicle’s assistance systems. For this purpose, Bosch has added a smart crash algorithm to the acceleration sensors in its MSC motorcycle stability control system. Should the sensors detect an accident, they report the crash to the app, which immediately sets the rescue process in motion. Once it has been registered, the lifesaving solution can be activated at any time, in any place – automatically in connected devices or at the push of a button.
The Japanese electronics company Sony has developed an electric car. The prototype, named the “Vision-S”, was presented by the company at CES in Las Vegas. Sony announced that it wants to “contribute to the achievement of safe, reliable, and comfortable mobility experiences”.
According to media information, the electric vehicle was developed jointly with the Austrian contract manufacturer and supplier Magna Steyr. Bosch, Continental and ZF were apparently also involved.
The prototype features Sony’s software, image and sensor technology. A total of 33 sensors – including CMOS image sensors and ToF sensors – are embedded in the car to recognise people and objects inside and outside the vehicle. They are intended to provide a “safety cocoon” to protect people both inside and outside. The “360 Reality Audio” system is used to create an excellent sound experience within the vehicle. For this purpose, loudspeakers are built into each seat and surround the passengers with sound. Opposite the front seats is a panoramic screen, where passengers can access content via an intuitive user interface.
Bosch’s new Virtual Visor greatly improves driver safety and comfort
Sun glare causes thousands of automotive accidents a year, almost two times more than any other weather-related condition.
Virtual Visor features a single, transparent LCD panel, a driver-facing camera with AI facial detection and analysis and tracking software.
Dr. Steffen Berns: “Some of the simplest innovations make the greatest impact, and Virtual Visor changes the way drivers see the road.”
Bosch at CES®: Virtual Visor named Best of Innovation in CES 2020 Innovation Awards; see it in action at booth #12041 in Central Hall.
Farmington Hills, Michigan – Bosch is rethinking driver safety and comfort, bringing one of the most overlooked interior components into the spotlight, the sun visor. The sun causes twice as many car accidents as any other weather-related condition due to temporary blindness. The National Highway Traffic Safety Administration reports thousands sun glare-related car accidents each year, and another study indicates the risk of a car crash is 16 percent higher during bright sunlight than normal weather. The traditional sun visor is not equipped to adequately address this safety concern. At best, it blocks some of the sun from your eyes but along with it, some of your view is blocked as well.
Bosch is offering a solution with the revolutionary Virtual Visor, a transparent LCD and intuitive camera, which replaces the traditional vehicle sun visor completely. As the first reimagined visor in nearly a century, Bosch’s technology utilizes intelligent algorithms to intuitively block the sun’s glare and not the view of the road ahead.
“For most drivers around the world, the visor component as we know it is not enough to avoid hazardous sun glare – especially at dawn and dusk when the sun can greatly decrease drivers’ vision,” said Dr. Steffen Berns, president of Bosch Car Multimedia. “Some of the simplest innovations make the greatest impact, and Virtual Visor changes the way drivers see the road.”
The Virtual Visor, which was honored as a Best of Innovation in the CES 2020 Innovation Awards, will debut at CES 2020 in Las Vegas. The Virtual Visor was also named as an honoree in the awards competition, which recognizes products across 28 categories. Virtual Visor received the Best of Innovation for the In-Vehicle Entertainment & Safety category, as it received the highest ratings from a panel of judges that includes designers, engineers and members of the tech media.
A sun visor fit for the future
Virtual Visor links an LCD panel with a driver or occupant-monitoring camera to track the sun’s casted shadow on the driver’s face. The system uses artificial intelligence to locate the driver within the image from the driver-facing camera. It also utilizes AI to determine the landmarks on the face ‒ including where the eyes, nose and mouth are located ‒ so that it can identify shadows on the face. The algorithm analyzes the driver’s view, darkening only the section of the display through which light hits the driver’s eyes. The rest of the display remains transparent, no longer obscuring a large section of the driver’s field of vision.
“We discovered early in the development that users adjust their traditional sun visors to always cast a shadow on their own eyes,” said Jason Zink, technical expert for Bosch in North America and one of the co-creators of the Virtual Visor. “This realization was profound in helping simplify the product concept and fuel the design of the technology.”
The creative use of liquid crystal technology to block a specific light source decreases dangerous sun glare, driver discomfort and accident risk; it also increases driver visibility, comfort and safety.
Innovation from the recycling bin
From the original ideation and concept phase to testing and prototyping, Virtual Visor is a bottom-up solution made possible through the innovation culture established at Bosch. Employees are encouraged to apply lean startup methodologies to confirm customer benefits, market potential and feasibility for new ideas, which are then validated by peers and approved for development.
“We’ve built a culture around empowering our associates by putting them in the driver’s seat,” said Mike Mansuetti, president of Bosch in North America. The Virtual Visor was developed by a team in North America as part of Bosch internal innovation activities. “As a leading global technology provider, we understand that innovation can come from any level of an organization, and we want to see that grow.”
A group of three powertrain engineers, led by Zink, developed the idea for Virtual Visor and created prototypes in their free time in order to secure internal funding for the project concept.
“Like many early-stage ideas, we were working with limited capital and resources,” said Zink. “The original prototype, we used to first pitch the concept, was made from an old LCD monitor we recovered from a recycling bin.”
The Virtual Visor team received mentorship from Bosch executives as they sought funding and developed additional versions of the product. Ultimately the product was transitioned into the Bosch Car Multimedia division.
It takes less than five seconds for a hacker to compromise a standard keyless vehicle entry system. Among experts,this is known as a relay station attack. A Bosch key app is going to change all that. “Our Perfectly Keyless system revolutionizes keyless entry systems. It is the ‘key’ to preventing digital car theft,” says Harald Kröger, president of the Bosch Automotive Electronics division. The special thing about the solution is that the Bosch technology works with a virtual key stored in the smartphone.Sensors installed in the car recognize the owner’s smartphone as securely as a fingerprint and open the vehicle only for them. Digital key management links the app and the vehicle via the cloud. With Perfectly Keyless, Bosch is thus doing something that no other keyless entry system has done before, namely offering both convenience and security. The new smartphone-based key can be used in cars, entire car-sharing fleets, and commercial vehicles. Bosch believes this system with its built-in security lock has huge market potential worldwide.
Bosch revolutionizes keyless entry
With conventional keyless entry systems,the car key still needs to be carried in a jacket or suit pocket, for example.To open the door and start the engine, it communicates with the car using a radio signal in the low frequency (LF) or ultra high frequency (UHF) range. In the race against thieves, the automotive industry is constantly refining existing systems. It’s like a marathon. “Now, with Perfectly Keyless, Bosch is launching into a sprint in the development of digital vehicle entry systems.Our motto is revolution, not evolution,” Kröger says. Instead of transmitting data via low or high frequency radio technology, the Bosch system uses the smartphone as virtual key and Bluetooth as the transmission technology. This means that the car key can stay at home. And thanks to its decades of experience in semiconductors, Bosch is in a position to make this connection as secure as a fingerprint. Every smartphone contains tiny microchips to manage communication via Bluetooth, and these play a key role in the Bosch solution.Together with sensors installed in the vehicle and a special control unit, they form a system that opens the door only for the smartphone containing the virtual key that fits in the Perfectly Keyless system’s digital lock. The system blocks signals from other smartphones or from electronic devices that manipulate the radio transmission. In this way, Perfectly Keyless protects against unauthorized access.
A keyless journey
Virtual vehicle keys on smartphones have long been a feature of car-sharing fleets. These vehicles don’t move until their operator authorizes entry via the cloud; only then can a user unlock the vehicle, start it, and lock it again using an app. This conversation between the phone and the vehicle uses near-field communication (NFC), a wireless protocol for sharing data over distances of a few centimeters. For this to work,users must take out their smartphone before each journey and hold it up to a marked area on the vehicle. Only then can the system recognize the user and unlock the doors. With Bosch Perfectly Keyless, the smartphone can also stay in its pocket. This means greater ease of use for drivers, and car sharing users benefit from the added convenience. The Bosch solution also works in trucks and for entire fleets of commercial vehicles. That means no more manual administration of vehicle keys, physical handover, or hassle when a key is lostor stolen. If the smartphone is lost or stolen, and the Perfectly Keyless app with it, the digital key can be simply deactivated online, thus blocking access to the vehicle.
Throughout the six generations of success, the Lexus ES has been famous for its smooth, quiet and refined ride. Now this signature quality has been taken to an even higher level in the all-new 7th generation of the luxury sedan thanks to a detailed and innovative approach to suspension design and packaging.
The attention to detail produced a new Swing Valve Shock Absorber with an ultra-low velocity valve – a world-first in the industry. In simple terms, this innovation makes sure an appropriate damping force is provided when even the slightest movement is experienced in the car’s wheels and suspension. This makes for a comfortable, unruffled ride and a stable feel, whether you’re pulling away slowly, or driving at speed on the highway.
The benefit is gained in the way the flow of oil is controlled inside a new valve arrangement. As well as a main valve, the ES’s shock absorbers have an additional ultra-low velocity valve, which allows for very low oil speed operation; at low to high oil speeds, the main valve opens to suppress the damping force, giving supple ride comfort.
Delivering superior standards of both handling stability and ride comfort is a big ask but it was a challenge Lexus was ready to meet by drawing up a new double wishbone rear suspension design. Critically, the system’s trailing arms have been located with pinpoint accuracy to give the set-up the rigidity it needs to give true, linear steering response to the driver’s use of the wheel and excellent handling stability.
Much of the testing to evaluate the new ES’s ride and handling took place in Europe where the development team could be sure of a wide range of road types and surfaces, from no-limit German highways, to winding mountain routes and urban streets with rough surfaces. Further testing was carried out on track, including at the famous Nürburgring, and in California.
At the same time as Lexus’ engineers determined the optimum suspension performance, they also took care to produce a design that doesn’t compromise the size or convenient shape of the boot.
