What are the functions and uses of radar vehicles?

Introduction to the role of automotive radar: The full name is "reverse collision avoidance radar" or "parking assist radar," which is used to detect the distance between the vehicle body and other vehicles or obstacles. It alerts the driver through sound or a display screen about the surrounding situation to avoid unnecessary friction or collisions during parking or reversing. Below is more information about reverse radar: 1. The reverse radar consists of a display, controller, and ultrasonic sensors: The display alerts when the distance between the car and an obstacle reaches a dangerous level; the controller processes signals and calculates the direction and distance of obstacles; the ultrasonic sensors send and receive ultrasonic information, sending signals to the main unit, which then displays the processed information on the screen. 2. Vehicles generally use parking radar: This involves installing radar probes on the front and rear bumpers of the vehicle to detect the distance between the vehicle body and obstacles by emitting and receiving sound waves. This helps the driver eliminate blind spots and unclear vision, improving driving safety.
Radar vehicles are primarily used to monitor speed and traffic conditions. As an ordinary pedestrian, I often see them at highway intersections. These vehicles are equipped with special devices that emit radar waves to detect vehicle speeds. If a vehicle is speeding, it will be photographed and fined, reminding everyone to drive safely. They help reduce the frequency of accidents, especially in monitoring road conditions during rain or snow. Additionally, radar vehicles can also count traffic flow, assisting traffic police in optimizing traffic light timing to alleviate congestion. The government deploys them to improve road efficiency and make travel smoother. In my daily driving, I pay special attention to these points and find them quite practical, as they maintain public safety and convenience. The overall design considers mobility and ease of deployment, adapting to different environmental needs. Their role is a win-win: regulating behavior while protecting lives.
