Driver assistance systems
Based on surround sensors such as radar, video and/or ultrasound, driver assistance systems sense and interpret the surroundings. They assist the driver in various driving situations and increase the driving comfort. In addition, driver assistance systems improve driving safety by supporting the driver in critical driving situations that require rapid and safe action.
Bosch is a member of several initiatives that aim to promote the public awareness of and knowledge about driver assistance systems: the European initiative “eSafety Aware!”, the German information campaign "bester Beifahrer" by the German Road Safety Council (DVR), as well as the “Driving for Better Business” campaign by the British Department for Transport.
- Routine tasks are taken over
- More comfortable and relaxed driving, parking and maneuvering
- Modular system design allows for varied functional extension
- Synergies due to expertise in system development and networking
Adaptive cruise control (ACC)
Adapts the speed in line with the flow of traffic
ACC, the adaptive distance and speed control system, actively assists the driver in keeping a safe distance from the vehicle in front. While driving, ACC maintains the speed set by the driver and can automatically adapt this speed to changing traffic by throttling back, braking or accelerating. The ACC Stop & Go version can bring the vehicle to a standstill and will resume automatically when instructed by the driver.
Side view assist
Keeping an eye on the blind spot
The side view assist is the world's first ultrasonic-based system for monitoring the blind spot. The system helps to reduce the risk of accidents while changing lanes. Two ultrasonic sensors on each side of the vehicle serve as electronic eyes and monitor the space in the adjacent lane, allowing the system to cover the dangerous blind spot. If another vehicle is situated in the monitored area, the driver is alerted to the potential danger by means of a warning sign in the side mirror. If the driver fails to spot or ignores this warning and activates the turn signal to change lanes, the system can also trigger an audible warning. The system recognizes stationary objects on or alongside the road, such as guardrails, masts or parked vehicles, as well as the driver's own overtaking maneuvers – and does not trigger the warning in this case.
The side view assist is active between 5 and 180 km/h. The system assists the driver in complex traffic situations involving low relative speeds, making driving easier, especially in urban traffic and on multilane roads.
Guides the vehicle into a suitable space
An ultrasonic sensor integrated into the side of the front bumper scans the side of the road to detect a suitable parallel or perpendicular space. Once a parking space is detected, the system alerts the driver. If the driver activates the assistant, the system calculates the best possible path into the space as well as the necessary steering maneuver. Once complete, the parking assistant takes control by allowing the driver to let go of the steering wheel and only control the parking maneuver by accelerating and braking.
The assistant also helps with pulling out of the parking space. Parking assistant technology takes control of all steering maneuvers in order to direct the car into a position from which the driver can safely pull out of the space.
Can warn of surrounding obstacles while parking
Using ultrasonic sensors integrated into the vehicle’s bumper, the system monitors the area immediately ahead of and/or behind the vehicle, and recognizes obstacles in real time. If an object is detected, the system sends a signal to the driver indicating the distance of that object.
Rear view system
A new perspective on parking and maneuvering
Modern vehicles often offer the driver only a limited view of the car’s surroundings. Increasingly smaller side and rear windows, combined with a vehicle shape that is strongly influenced by aerodynamics and pedestrian protection, is making safe and precise maneuvering extremely difficult.
A near-range camera located in the back of the vehicle assists drivers reversing by displaying the image onto the vehicles dashboard. The camera in the vehicle’s rear is automatically activated when reverse gear is engaged and allows the driver to determine in real time whether the path is clear. Optionally, the vehicle’s path can be shown dynamically on the camera image with the help of colored lines. These display the vehicle’s trajectory according to the current steering wheel angle and indicate when the steering wheel must be turned.
