Abstract

본 발명은 차량의 후미로 부터 시 사각지대로 접근하는 다른 차량의 출현을 감지하는 차량 측방 장애물 감지장치에 관한 것이다. 본 발명에 따른 차량 측방 장애물 감지장치는 차량 후미의 양측에 배치된 초음파 센서에 의해 근접하는 차량을 감지하며 상기 센서에 의해 감지된 신호로 부터 장애물 검출기에 의해 장애물 존재를 나타내는 검출신호를 발생한다. 마이크로 프로세서는 상기 장애물 검출신호에 근거하여 장애물의 접근거리를 계산하며, 이 접근거리는 차량의 주행 속도에 상응하는 공기의 흐름에 기인한 상기 초음파 센서의 오동작 가능한 범위내에서 출현하는 모든 장애물 검출신호를 무시하도록 프로그램된다.The present invention relates to a vehicle side obstacle detection device for detecting the appearance of another vehicle approaching the blind spot from the rear of the vehicle. The vehicle side obstacle detecting apparatus according to the present invention detects a vehicle that is approached by ultrasonic sensors disposed at both sides of the rear of the vehicle and generates a detection signal indicating the presence of an obstacle by an obstacle detector from the signal detected by the sensor. The microprocessor calculates the approaching distance of the obstacle based on the obstacle detecting signal, and the approaching distance receives all the obstacle detecting signals appearing within the malfunctionable range of the ultrasonic sensor due to the flow of air corresponding to the traveling speed of the vehicle. It is programmed to be ignored.
