Lidar sensor: In addition to radar, video, and ultrasonic sensors, Bosch also uses lidar sensors in its automated test vehicles. Bosch’s radar and video sensors capture and transmit important real-time traffic data for the creation of high-resolution maps for automated driving. The maps provide vehicles with information about changing traffic situations, such as traffic jams or construction, that fall outside the area on-board sensors can monitor. Maps: Without high-resolution, up-to-date maps, there can be no automated driving. In a standard master cylinder, the power provided by the booster is transformed into hydraulic pressure. The control unit calculates the triggering signal for the electric motor, which uses a two-stage transmission to convert its torque into the required power assistance. In the iBooster, the actuation of the brake pedal is recorded by the built-in pedal-travel sensor and transmitted to the control unit. It can be used in all powertrain concepts and is especially well suited for hybrid and electric vehicles. IBooster: With the iBooster, Bosch has developed a vacuum-independent, electromechanical brake booster that meets the requirements for modern braking systems. This information is superimposed on the vehicle’s surroundings in such a way that the two seem to blend seamlessly at a distance of around two meters ahead of the vehicle. ![]() By using head-up displays, Bosch puts information such as speed, navigation prompts, and warnings directly in the driver’s field of view. With its innovative display instruments, Bosch is already offering promising solutions in this area as well: the TFT instrument cluster, for instance, offers maximum flexibility in processing combined with brilliant clarity. The driver must be able to intuitively understand and use the system. HMI: Automated driving will change the human-machine interface, and calls for modern concepts for communication between car and driver. Bosch offers ESP as a modular concept that offers the right system for all circumstances and requirements. In this instance, the ESP brake control system and iBooster electromechanical brake booster (see below) can independently brake the vehicle without the driver having to intervene. To retain maximum control over these systems in the event of the failure, redundancy must be built into the system as a safeguard. Delegating responsibility for driving to the vehicle places particular demands on safety-critical systems such as the brakes. Department of Transportation and National Traffic Highway Safety Association, for example.ĮSP: The electronic stability program also plays a key role when it comes to automated driving. This technology will enable automakers to comply with the safety requirements as proposed in the Federal Automated Vehicles Policy documents from the U.S. Even in fall-back mode, fail-operational capability allows drivers and automated cars to continue using essential steering functions while maintaining about 50 percent electric steering support in the rare case of a malfunction. ![]() ![]() For instance, connected vehicles are warned in advance of danger spots before a blind bend or hilltop and can ease off the accelerator in preparation.Įlectric steering: Fail-safe, electric power steering is a key technology for automated driving. This is beneficial for the comfort and safety of the driving experience. Connected Horizon is what allows automated vehicles to think ahead. This system enables a dynamic preview of the upcoming route and corresponding adjustments to driving strategy. This can be achieved only by connecting the vehicle to a server, for which Bosch developed its Connected Horizon solution. For instance, they need real-time traffic data on congestion and accidents. Few automotive suppliers worldwide have as much knowledge in this area as Bosch, in part because the supplier of technology and services manufactures most of the components needed for automated driving listed below:Ĭonnected Horizon: Automated vehicles rely on environmental information – information that goes beyond what sensors can gather. The key to success is an in-depth understanding of all vehicle systems. Automated driving impacts the entire car: its powertrain, brakes, steering, display instruments, navigation, and sensors, as well as connectivity inside and outside the vehicle.
