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.

From a technical perspective, let's discuss how trajectory reversing cameras work. They generate guiding lines through the coordination of cameras and sensors. When you turn the steering wheel, the computer calculates wheel rotation, causing the lines to curve accordingly to display the predicted path. The color coding typically uses red for warning and green for safety, helping you judge distance from obstacles. It's simple to use - just engage reverse gear and watch the screen; the moving lines show whether your reversing direction is accurate. This feature is particularly helpful for parking or U-turns, but remember to proceed slowly in poor lighting conditions.

Safe driving is crucial. When using the trajectory reversing camera, pay attention to the color prompts of the trajectory lines on the screen. The red zone indicates high danger, and you should stop immediately; the dynamic lines change with the steering wheel to help you predict the vehicle's turning, but you should also turn your head to check the actual surroundings. I've seen people rely too much on this feature and forget to check the side mirrors, leading to minor accidents, so always observe and confirm before reversing. Be extra cautious when reversing in rain or at night—slowing down reduces risks. Remember, this feature is only an assistive tool.
