The laser sensor and distance control ECU transmit the data for general vehicle control and diagnosis function along the communication line.
The distance control ECU determines the presumed R information based on the signal from the steering wheel and yaw rate sensor.
The distance control ECU transmits the current vehicle speed and presumed R information to the laser sensor.
