摘　　要：针对汽车开启车门时容易撞上车门侧面高于车门门槛的盲区障碍物或与其他交通参与者发生碰撞这一问题,提出了一种基于超声波检测的车门安全开启检测及提醒系统,利用光电码盘的输出脉冲信号来测出车的瞬时速度,在车停下来及车门解锁时,汽车车门两端以及汽车尾部超声波检测到障碍物,ECU接收到超声波检测到的信息进行处理控制,当存在障碍物时警报系统发出对应的警报声提示及警报灯闪烁。避免打开车门时发生交通事故或者损坏车门。When the car opens the door, it is easy to hit the obstacle in blind area on the side of the door that is above the door threshold or hit other traffic participants. For this problem, a safety detection and reminder system for door safety based on ultrasonic is proposed. The instantaneous velocity of the vehicle is measured by using the output pulse signal of the photoelectric encoder, when the car stops and the door is unlocked, the ultrasonic located in the car door ends and the car＇s tail can detect the obstacle, and then the ECU receives the information detected by the ultrasonic wave for processing control. When there is an obstacle, the alarm system issues a corresponding alarm tone and the alarm light flashes to avoid traffic accidents or damage the door when opening the door.
