How to View the Trajectory Backup Camera?
3 Answers
To view the trajectory backup camera: 1. Green trajectory: Indicates a normal safety line, meaning the distance between the obstacle and the rear of the vehicle is large enough for reversing; 2. Yellow trajectory: Represents a deceleration line, with a distance of 60cm from the rear of the vehicle, allowing continued reversing; 3. Red trajectory: Signifies a warning line, with a distance of 30cm from the rear of the vehicle, indicating that you should stop reversing to avoid hitting rear obstacles. The backup camera is installed at the rear of the vehicle and consists of ultrasonic sensors, a controller, a display, and a buzzer. Its function is to inform the driver of surrounding obstacles through sound and a more intuitive visual display.
As an experienced driver, I remember feeling quite novel the first time I used this trajectory reversing camera. When you shift into reverse gear, the center console screen lights up, displaying the view behind the car with those colored lines indicating the trajectory. Red usually means you're about to hit something and need to stop immediately; green or yellow represents a safe distance. The key is the dynamic trajectory—when you turn the steering wheel, the lines curve accordingly, predicting the path the car will take while reversing. Practice a few times in an open area: first reverse straight into a parking spot, then try turning while reversing. Gradually, you'll master how to align the lines to back into the garage. Be cautious on rainy days or at night, as the camera might reflect light or have poor visibility—slow down for safety. This feature has truly made reversing much easier for me.
If you've just bought a car or have a new one, using the reversing trajectory display is quite straightforward. Once you shift into reverse gear, the screen automatically shows the view, with trajectory lines divided into static and dynamic types. The static lines are fixed curves that help you judge the direction, while the dynamic lines change in real-time as you turn the steering wheel, indicating the turning angle of the car body. My advice is to pay attention to the line colors on the screen: the red zone is the danger area—don’t get too close; the blue lines predict the wheel path. Combine this with checking the rearview mirror and a quick glance over your shoulder to ensure a smooth reverse. Remember not to focus solely on the screen—observing your surroundings more often is safer. This is especially useful when reversing in tight residential areas. Practice a few times, and you’ll get the hang of it.
