When the driver is reversing (gear pushed to R gear), the system starts and sends ultrasonic waves from the probe in the rear of the device to the rear of the car. After meeting obstacles, echo signals are generated, and the direction and distance of obstacles are judged by the controller after controlling and processing the echo signals. Finally, the display or buzzer will send out image and sound prompts, so that the driver can know when to reverse, easier and safer. 8. Sounding astern radar: Working principle: The probe in front of the vehicle has a working time of 30 seconds when the vehicle is reversing on the brake. The maximum effective range of reversing radar detection is 2.5 meters (0.8 meters in front of the vehicle). For different obstacles, the ultrasonic reflection intensity is different, and the detection distance is also different. Working mode: when the brake is pressed, the probe in front is energized and starts to work; when the reverse gear is pressed, the probe in rear is energized and starts to work Reasons for different operation of front and rear probes: When the brakes are applied, the car leans forward and is naturally further away from obstacles behind the car, so there is no need to detect obstacles behind the car. Similarly, when the car is in reverse gear, it is further behind and away from obstacles in front of it, so there is no need to detect and alarm. 二. Product function description 1.
