Networking Automotive Systems: Brake Assist
The FlexRay training system contains a brake assistant function. It combines the following:
- a distance sensor control unit
- a road condition sensor
- an ABS/ESP control unit, and
- an instrument cluster.
Two model cars simulate two vehicles tailgating. The FlexRay data bus transfers this state to the control unit for ABS/ESP, which then triggers the brakes to establish the safe distance again. The default value depends on the road condition (dry, wet, slick). The LIN data bus transmits the roadway’s condition to the radar sensor control unit.
Activating the high-pressure switch valve and the pump displays the brake’s function.
A high-speed CAN bus connection controls the corresponding indicator lamp in the instrument cluster.
The system can be expanded to an “active star” (773 959) with FlexRay components. The sensor control unit also has an available connection for a FlexRay/USB interface (773 960) to analyze the protocol on the computer.
The FlexRay lines can be completed with external resistors and are set for signal registration with an oscilloscope.
