倒车雷达，又称泊车辅助系统，或称倒车电脑警示系统。它是汽车泊车或者倒车时的安全辅助装置，由超声波传感器（俗称探头）、控制器和显示器（或蜂鸣器）等部分组成。它能以声音或者更为直观的显示告知驾驶员周围障碍物的情况，解除了驾驶员泊车、倒车和启动车辆时前后左右探视所引起的困扰，并帮助驾驶员扫除了视野死角和视线模糊的缺陷，提高驾驶的安全性。
现在市面上的倒车雷达大多采用超声波测距原理，驾驶者在倒车时，将汽车的挡位推到R挡，启动倒车雷达，在控制器的控制下，由装置于车尾保险杠上的探头发送超声波，遇到障碍物，产生回波信号，传感器接收到回波信号后经控制器进行数据处理，从而计算出车体与障碍物之间的距离，判断出障碍物的位置，再由显示器显示距离并发出警示信号，从而使驾驶者倒车时不至于撞上障碍物。整个过程，驾驶者无须回头便可知车后的情况，使停车和倒车更容易、更安全。
具体地说，倒车雷达的工作原理为：首先连接电源并打开，车辆进入倒挡时，探测器主机自动进入工作状态，同时显示器波段亮起。然后，用专用钻头在保险杠上开孔，并将探测器分别装入孔内。根据车主倒车和停车的习惯，四个探头探测器分别安装在汽车的尾部或者两侧安装两个。安装好探测器主机在适当的位置，将显示器夹在车内后视镜上，就开始正常工作。

Reversing radar, also known as the parking assist system, or reversing the computer alert system. It is car parking or reversing the safety of assistive devices, ultrasonic sensors (commonly known as the probe), the controller and display (or buzzer), and other components. It is more intuitive to voice or show that inform the driver of the barrier around the situation, lifting the driver's parking, and start reversing vehicles around before and after the problems caused by the visit and help the driver to remove the dead ends and vision blurred vision Deficiencies and improve driving safety.
Now the market reversing radar most of the ultrasonic ranging principle, driving in reverse, the vehicle will be pushed to the Shift R block to start reversing radar, under the control of the controller, installed in the rear bumper on the probe Sendultrasound, encounter obstacles, a signal, sensors after receiving the signal controller for data processing, thereby calculate the body and the distance between the obstructions, determine the location of obstructions, and then from display Show distance and issued warning signal, so that drivers will not hit obstacles when reversing. The whole process, drivers know they do not have to turn around the situation after the car, stopping and reversing it easier and more secure.
Specifically, reversing radar for the working principle: First, the power and open, inverted block vehicles from entering, the detector automatically enter the host state of work, band is on display at the same time. Then, using special drill hole in the bumper, and detectors were put into holes. According to owners of the habit of reversing and parking, four probe detectors were installed in the car or the tail on both sides of the installation of two. Host detectors installed in the appropriate position, the display caught in the rearview mirror on the car, began to work properly.
