Where is the Reverse Radar Switch?

Depending on the button layout of different car models, it is generally located on the button panel on the left side of the steering wheel or the central control panel. After turning on the reverse radar switch and shifting the gear lever into reverse, the reverse radar will start working. Reverse radar is a safety auxiliary device for parking or reversing a car. It can inform the driver of the surrounding obstacles through sound or more intuitive display, eliminating the troubles caused by the driver's peering around when parking, reversing, and starting the vehicle, and helping the driver to eliminate blind spots and blurred vision. When reversing, the reverse radar uses the principle of ultrasound. The probe installed on the rear bumper sends ultrasonic waves to hit obstacles and reflects these waves, calculating the actual distance between the car body and the obstacles, and then prompts the driver, making parking or reversing easier and safer. The reverse radar mainly consists of ultrasonic sensors, a controller, and a display or buzzer. Ultrasonic sensor: Its main function is to send and receive ultrasonic signals, then input the signals into the main unit, and display them through display equipment. Controller: It processes the signals and calculates the distance and direction between the car body and the obstacles. Display or buzzer: When the sensor detects that the car's distance from the obstacle reaches a dangerous distance, the system will issue an alarm through the display and buzzer to remind the driver. Millimeter-wave reverse radar is a type of reverse radar. It detects the presence and distance of obstacles through millimeter-wave radar probes, transmits them to the central controller, and achieves alarm and prompt functions. The millimeter-wave reverse radar adopts a multi-channel serial port control method with a central controller, which can achieve all-around detection and warning around the vehicle. Because it adopts high-frequency millimeter-wave detection, it overcomes the shortcomings of ultrasound, such as short working distance and unstable effects in harsh environments. It has good application effects in special vehicles, engineering vehicles, port and dock operation vehicles, cranes, and other large machinery industries. The advantages include stable detection, long detection distance, and no influence from rain, snow, or fog.
