DETECTION DEVICE AND DETECTION METHOD OF ULTRASONIC BLIND AREA OF VEHICLE FOR PREVENTING GROUND MISMEASUREMENT AND MISINFORMATION

摘要

Disclosed are an automobile ultrasonic blind area detection device and detection method for preventing ground misdetection and misinformation. The detection device comprises a plurality of ultrasonic sensors, each ultrasonic sensor is arranged to form a certain angle with the longitudinal center line of an automobile, the detection directions of the ultrasonic sensors are spaced by set angles to respectively correspond to different directions from the far end to the near end of a side lane blind area; the detection distances of the ultrasonic sensors are different, and decrease gradually from the far end to the near end of the side lane blind area; ground misdetection signals of the ultrasonic sensors are shielded, and useful signals detected by the ultrasonic sensors are extracted and combined into far-near continuous long-distance detection signals to cover an automobile side lane exterior mirror blind area and a visible area behind the blind area more widely. The detection device and the detection method can cover the automobile side lane exterior mirror blind area and the visible area behind the blind area more widely, and effectively ensure the detection performance of a blind spot monitoring system.
