ABSTRACT:
A plurality of ultrasonic sensors is provided in both front and rear bumpers of a vehicle to detect obstacles around the vehicle. Each sensor sets up a transmission frequency of an ultrasonic pulse signal that should be set up in a frequency adjustment circuit and a center frequency in filter processing in a filter circuit in response to a frequency setting frame transmitted from an EMU. The EMU stores a combination of the transmission frequency and the center frequency for each ultrasonic sensor.
