Abstract:
A vehicle perimeter monitor carried by a vehicle having a door mirror, the vehicle perimeter monitor comprising:a support member supporting the door mirror for movement relative to the vehicle; a transmitting antenna fixed on the support member for radiating a transmitted wave generated by a transmitting circuit to the perimeter of the vehicle through the door mirror; a receiving antenna fixed on the support member for receiving the transmitted wave reflected from obstacles existing near the perimeter of the vehicle to send a received information signal to a receiving circuit; an actuator for moving the support member so as to change a viewing direction of the door mirror while maintaining a fixed positional relationship between the door mirror, the transmitting antenna, and the receiving antenna; a processing unit for calculating the distance between the vehicle and the obstacles based on the received information signal and determining a danger degree of collision; and an indicator for notifying the result of calculation by the processing unit to a driver of the vehicle.
