How to judge the distance behind when reversing?
2 Answers
With a reversing camera, if the car behind is a sedan, when the red line on the central control screen aligns with its front bumper, the distance between the two vehicles is approximately 35 centimeters. If the vehicle behind is a commercial van or SUV, when the red line aligns with the lower edge of its front license plate, the measured distance between the two vehicles is about 30 centimeters. To use the parking sensors to judge the distance, when they emit a rapid alarm, the distance to the vehicle behind is generally within half a meter.
I usually like to use technological devices to assist with reversing, especially the reversing camera system. The screen displays the rear distance and viewing angle in real time, working in conjunction with the radar alarm sound to alert me. For example, when the distance number drops to 1 meter, it indicates that I'm very close, and it's time to stop. The reversing radar is also very practical—the faster the beeping sound, the closer the obstacle is. However, if the environment is noisy or the system malfunctions, I have to rely on sensory judgment. I also recommend regularly calibrating these devices to ensure accuracy. Once you develop this habit, reversing becomes much easier and safer, especially in mall parking lots or narrow streets, effectively avoiding scratches and collisions.
