Product Description
Microwave radar technology,Digital waterproof probe,Original car style,Safety assisted guidance
The back-up radar was developed based on the principle that bats fly at high speed in the dark without colliding with any obstacles. The probe is mounted on the rear bumper. Depending on the price and brand, there are two probes, three probes, four probes, six probes, eight probes, ten probes and twelve probes, mainly mounted on the front and rear bumpers
The probe can radiate over a maximum range of 120 degrees horizontally and 70 degrees vertically, and search for targets left and right, up and down. Its biggest advantage is that it can detect obstacles below the bumper and difficult for the driver to see from the rear window, and alarm, such as flower beds, road shoulders, and children squatting behind the car.
The display of the back-up radar is mounted on the rear view mirror. It constantly reminds the driver how far the car is from the object behind it. When the dangerous distance is reached, the buzzer will start to sound with intermittent/continuous rapid sound to alert the driver to approach the obstacle and stop in time.
Most reversing radars use the principle of ultrasonic ranging. When the driver is reversing, the gear is pushed to R, and the system automatically emits ultrasonic waves from the probe installed at the rear of the car to the rear of the car. When encountering obstacles, an echo signal is generated, and the controller After controlling and processing the echo signal, the direction and distance of the obstacle are determined.
The working principle of the astern radar is composed of ultrasonic sensors, controllers and displays. It can inform the driver of the surrounding obstacles through sound or more intuitive display, which alleviates the trouble caused by the visit of the driver in front, after, left and right directions when parking, reversing and starting the vehicle, and helps the driver eliminate the defects of visual blindness and blurred vision, thereby improving driving safety.
