ICC sensor is installed on the front of the bumper and detects a vehicle ahead by using millimeter waves.
ICC sensor detects radar reflected from a vehicle ahead by irradiating radar forward and calculates a distance from the vehicle ahead and relative speed, based on the detected signal.
ICC sensor transmits information for ICC from the vehicle to ADAS control unit via ITS communication.
