How is the reverse parking sensor works?

reverse parking sensor, also known as the Park Assist system, or reversing a computer warning system. It is the car parking or reversing safety aids, from the ultrasonic sensors (commonly known as probes), controller and display (or buzzer), etc. components. It can use sound or a more intuitive display around the obstacles of this pilot to lift the driver parking, reverse and start a motor vehicle arising from all around to visit troubled, and to help the driver to remove the dead, and blurred vision defects, improve driving safety.

Most of the market is now reversing radar, ultrasonic distance measurement principle, motorists reversing the vehicle's gear pushed R gear, start parking sensor, under the control of the controller from the device on the rear bumper of the probe Ultrasonic waves are sent an obstacle to produce echo signals, sensors echo signal received by the controller, data processing, thus calculating the distance between the body and the obstacles, determine the location of obstructions, and then by the display shows the distance and send warning signals, so that reversing it without the driver hit the barrier. The whole process, the driver then we can not go back to the rear, thereby making parking and reversing easier and safer.


Specifically, reversing radar works as follows: First, connect power and turn the vehicle into reverse gear, the detector automatically enter the work of the host state, while display-band light. Then, with special drill holes in the bumper, and probe into hole, respectively. According to the customary owners of reversing and parking, four probe detectors were installed in the rear of the car, or both sides of the installation of two. Detectors installed the host at the appropriate location, the display folders in the car rear view mirror, and started work.
