Test drive Bosch presents impressive innovations in Frankfurt

The main trends are electrification, automation and connectivity.

For decades, Bosch has symbolized progress in the automotive industry. At the 66th Frankfurt International Motor Show, the technology company is presenting solutions for the electrified, automated and connected cars of the future. Bosch booth - A03 in hall 8.

Diesel and petrol engines - pressure increases

Diesel injection: Bosch increases the pressure in the diesel engine to 2 bar. The higher injection pressure is a decisive factor in reducing NOx and particulate matter emissions. The higher the pressure, the finer the fuel atomization and better mixing with the air in the cylinder. Thus, the fuel burns completely and as cleanly as possible.

Digital speed control: This new diesel technology significantly reduces emissions, fuel consumption and combustion noise. Unlike previous pre-injection and primary injection systems, this process is split into many small fuel injections. The result is controlled combustion with very short injection intervals.

Direct petrol injection: Bosch increases the pressure in petrol engines to 350 bar. This results in better fuel spray, more efficient mixture preparation, less film formation on the cylinder walls and shorter injection times. The emission of solid particles is significantly less compared to the 200 bar system. The advantages of the 350 bar system stand out at high loads and dynamic engine conditions, or in other words, at high accelerations and high speeds.

Turbocharging: The engine's air intake system plays an important role in meeting stringent emission standards. The well-synchronized combination of turbocharging, exhaust gas recirculation and related control unit functions further reduces engine emissions (including nitrogen oxides) even in real road conditions. In addition, fuel consumption in European driving mode can be reduced by another 2-3%.

Variable geometry turbine: Bosch Mahle Turbo Systems (BMTS) has developed a new generation of variable geometry turbines for exhaust gas turbochargers. They are based on a principle that will be applied much more widely in the gasoline engines of the future. It is a great achievement that at high temperatures the turbochargers do not deform as much and withstand continuous loads at 900 ºC. BMTS is working on prototypes capable of withstanding 980 ºC. Thanks to new technology, engines are becoming more powerful and economical. This also applies to diesel - as the angle of attack of the turbine wheel decreases, the efficiency of the variable geometry turbine increases.

Intelligent drive - reduced emissions and fuel consumption

Electronically controlled diesel particulate filter: Bosch controls the regeneration of the diesel particulate filter using the so-called "Electronic horizon", i.e. based on route navigation data. Thus, the filter can be restored both on the highway and in the city to operate at full capacity.

Providing Intelligent Traction: Electronic Horizon technology provides a detailed view of the route. The navigation software knows that it is following a city center or low-traffic area after a few kilometers. The car pre-charges the battery so you can switch to all-electric mode in this area without any emissions. In the future, the navigation software will also interact with traffic data from the Internet, so the car will know where the traffic is and where the repairs are.

Active Accelerator Pedal: With the active accelerator pedal, Bosch has developed a new fuel-saving technology – a slight vibration informs the driver of the pedal position at which fuel consumption is optimal. This saves up to 7% fuel. Together with assistance systems such as adaptive cruise control, the pedal becomes a warning indicator – in combination with navigation or a traffic sign recognition camera, the innovative Bosch accelerator pedal warns the driver of vibration if, for example, the vehicle is approaching a dangerous curve at high speed.

Electrification – increased mileage through consistent system optimization

Lithium-ion technology: To become more popular in the coming years, electric vehicles will need to become significantly cheaper. Battery technology plays a key role here – Bosch expects batteries to have twice the energy density at twice the price of today by 2020. The concern is developing next-generation lithium-ion batteries with GS Yuasa and Mitsubishi Corporation in a joint venture called Lithium Energy and Power.

Battery systems: Bosch is taking a variety of approaches to stimulate the development of new high-performance batteries. The innovative Bosch Battery Management System is part of the Battery System that monitors and controls the elements of the entire system. Intelligent battery management can increase vehicle mileage by up to 10% on a single charge.

Thermal Management for Electric Vehicles: A larger battery isn't the only way to extend the life of an electric vehicle on a single charge. Air conditioning and heating significantly reduce mileage. Bosch is introducing intelligent air conditioning control that is much more efficient than previous versions and increases mileage by up to 25%. A system of variable pumps and valves stores heat and cold at their source, such as power electronics. The heat can be used to heat the cab. A complete thermal management system reduces the energy requirement for the heating system in winter by up to 60%.

48-volt hybrids: Bosch unveiled the second generation of its 2015-volt hybrids at the 48 Frankfurt International Motor Show. The modified starting electrification level saves up to 15% fuel and delivers an additional 150 Nm torque. In the second generation of 48-volt hybrids, the electric motor is integrated into the transmission. The electric motor and combustion engine are separated by a clutch that allows them to transmit power to the wheels independently of each other. Thus, the car can park and drive in traffic jams in a fully electric mode.

Towards Automated Driving – Helping You Avoid Obstacles, Curves and Traffic

Obstacle Avoidance Assist System: Radar sensors and video sensors identify and measure obstacles. With targeted maneuvers, the assistance system also helps inexperienced drivers to avoid difficulties on the road. The maximum steering angle is reached 25% faster, and the driver is safe even in the most difficult driving situations.

Left turn and U-turn assist: when approaching left and in reverse, an oncoming vehicle can easily drive in the oncoming lane. The assistant monitors oncoming traffic using two radar sensors in front of the vehicle. If it does not have time to turn, the system does not allow starting the car.

Traffic jam assist: Traffic jam assist is based on the sensors and functions of the ACC Stop & Go and the lane departure warning system. The system follows the front vehicle at speeds up to 60 km / h in heavy traffic. Traffic jam assist accelerates and stops on its own, and can also keep the vehicle in the lane with light steering strokes. The driver only needs to monitor the system.

Highway Pilot: Highway Pilot is a highly automated feature that takes full control of the car on the highway. Prerequisites: Reliable monitoring of the overall vehicle environment using sensors, accurate and up-to-date maps, and powerful pluggable control units. As soon as the driver leaves the highway, he can activate the function and relax. Before passing through a highly automated section of the road, the pilot informs the driver and invites him to get behind the wheel again. Bosch is already testing this feature on the highway in specially equipped vehicles. After the harmonization of legal provisions, in particular the Vienna Convention on Road Traffic, UNECE Regulation R 79, in 2020 the pilot project on the motorway will be put into mass production.

Stereo Camera: With a distance of only 12 cm between the optical axes of the two lenses, the Bosch Stereo Camera is the smallest system of its kind for automotive use. It recognizes objects, pedestrians, road signs, free spaces and is a mono-sensor solution in a number of assistance systems. The camera is now standard on all models. Jaguar XE and Land Rover Discovery Sport. Both vehicles use a camera in their urban and suburban emergency braking systems (AEB City, AEB Interurban). Jaguar, Land Rover and Bosch prototypes were showcased in the New World of Mobility sector at IAA 2015, showcasing more of the functions of a stereo camera. These include pedestrian protection, site repair assistant, and clearance calculation.

Smart Parking - detect and reserve free parking spaces, secure and automated parking

Active Parking Management: With Active Parking Management, Bosch makes it easier for drivers to find an available parking space and helps parking operators get the most out of their options. Floor sensors detect whether a parking space is occupied or not. The information is transmitted by radio to a server, where the data is placed on a real-time map. Drivers can download the map to their smartphone or display from the internet, find an empty parking spot and navigate to it.

Reversing Assistant: The intelligent trailer parking system offers drivers convenient control of a vehicle with a trailer via a smartphone or tablet on the street. It is based on the interface for electric power steering, brake and engine control, automatic transmission, and steering angle measurement function. With the smartphone app, the driver can pre-select the direction and speed of travel, even outside the vehicle. The truck and trailer can be operated and parked with one finger.

Public parking: Roadside parking is very rare in urban centers and some residential areas. With public parking, Bosch makes it easy to find a parking spot – as the car passes parked cars, it measures the distance between them using the sensors of its parking assistant. The registered information is transmitted on a digital road map. Thanks to intelligent data processing, the Bosch system confirms the information and predicts the availability of parking spaces. Cars nearby have real-time access to the digital map and their drivers can navigate to vacant spots. Once the size of the available parking spaces has been determined, the driver can select a suitable parking space for their compact car or camper. The more cars will be involved in the parking system in settlements, the more detailed and up-to-date the map will be.

Multi-camera system: Four close-range cameras installed in the vehicle provide the driver with full visibility when parking and shifting. With a 190-degree aperture, the cameras cover the entire area around the vehicle. Special imaging technology provides a high quality XNUMXD image without any clutter on the on-board display. The driver can choose the perspective and magnification of the image so that he can see even the smallest obstacles in the parking lot.

Automated Valet Parking: Automated Valet Parking is a Bosch feature that not only frees the driver from searching for a parking space, but also parks the car completely independently. The driver simply leaves the car at the entrance to the parking lot. Using a smartphone app, he instructs the car to find a parking space and then return the same way. Fully automated parking requires an intelligent parking infrastructure, on-board sensors and communication between them. The car and the parking lot communicate with each other - sensors on the floor indicate where there are empty spaces and transmit information to the car. Bosch develops all components for fully automated parking in-house.

More safety, efficiency and driver comfort – Bosch display and connectivity systems

Display systems: navigation systems, new vehicle sensors and cameras, and the vehicle's internet connection provide drivers with a variety of information. Display systems should prioritize and present data in a way that can be understood intuitively. This is the task of the freely programmable Bosch displays, which present the most important information in a flexible and timely manner. The technology can be complemented by a combined head-up display that displays important information directly in the driver's field of view.

Bosch is also showcasing an innovative user interface that complements visual and acoustic interaction with tactile elements. When operating the touchscreen, the driver has a tactile sensation as if his finger was touching a button. He needs to press harder on the virtual button to activate it. The driver is not distracted from the road, as it is not necessary to look at the display.

Connected Horizon: Electronic Horizon technology continues to provide grade and curve data to complement navigation information. In the future, Connected Horizon will also provide dynamic data on congestion, accidents and repair zones. This allows drivers to travel safer and get a better image of the road.

With mySPIN, Bosch offers an attractive smartphone integration solution for perfect vehicle connectivity and quality service. Drivers can use their favorite iOS and Android smartphone apps in a known way. Applications are reduced to the most important information, which is displayed on the onboard display and controlled from there. They are tested for use while driving and distract the driver as little as possible, ensuring maximum safety.

Traffic ban warning: 2 warnings for vehicles driving in prohibited directions are broadcast on the radio in Germany alone every year. The warning signal is usually delayed as the nightmare route ends no sooner than 000 meters, in many cases fatal. Bosch is developing a new cloud solution that will alert in just 500 seconds. As a pure software module, the warning function can be integrated into an existing infotainment system or smartphone apps.

Drivelog Connect: With the Drivelog Connect app, the Drivelog mobile portal also offers a solution for connecting older car models. All you need is a compact radio module, the so-called Dongle, and a smartphone app. The platform gives advice on economical driving, explains error codes in an accessible form, and in the event of an accident, can contact technical support on the road or a car service.
