The distance from the vehicle ahead and a relative speed are calculated by using the ICC sensor and an ICC
sensor signal is transmitted to the ADAS control unit via ITS communication. When judging the necessity of
warning according to the received vehicle ahead detection signal, the ADAS control unit transmits a buzzer
output signal and meter display signal to the combination meter via CAN communication.
