特徴とする自動車用後方障害物検知装置。 A rear sensor installed at the rear of the vehicle that emits ultrasonic waves toward the rear at predetermined time intervals, and receives reflected waves when the emitted ultrasonic waves hit rear obstacles, and the transmitted waves from the rear sensor are transmitted. a distance calculation unit that calculates the distance between the rear of the vehicle and the obstacle from the time it takes to receive the reflected wave and issues a distance signal; and a distance calculation unit that operates based on the distance signal from the distance calculation unit to alert the driver. In the rear obstacle detection device, the distance signal calculated by the distance calculating section based on the reception of the reflected wave of the rear sensor is stored, and when the reception of the reflected wave of the rear sensor stops, the distance signal is immediately before the above alarm stops. A remaining distance calculation section is provided which subtracts a backward movement amount signal of the automobile calculated based on the backward vehicle speed from the distance signal of the vehicle and generates a subtraction signal, and the subtraction signal of the remaining distance calculation section connects the alarm operation of the alarm section without interruption. A rear obstacle detection device for an automobile, characterized in that:
