Driver assistance system for use in motor vehicle, has sound waves transmitting and receiving sensors connected with controller by serial bus system that is formed as shift register, and bit string providing bit for sensors and controller

摘要

The system (101) has sound waves transmitting and receiving sensors (S1, S2, S3) for monitoring vehicle surrounding. The sensors are connected with a controller (15) by a serial bus system (20) that is formed as a shift register. An initialization sequence is provided for addressing the sensors and a communication sequence is provided for data exchange in a transmitting and receiving operation of the sensors. A bit string is transmitted via the bus system for the data exchange to provide a bit for each sensor and the controller. An independent claim is also included for a method for controlling a driver assistance system.
