Methods to display reversing trajectory in rearview camera: 1. Meaning of reversing trajectory lines. Red arc: Represents the trajectory line of the rear wheels when reversing with the steering wheel fully turned. Yellow line: Considered as a deceleration line, the position at the bottom of this line is 60 cm from the rear of the car, and you can continue reversing at a reduced speed. Green line: Represents the actual trajectory line of the rear wheels when reversing in the current state. 2. Judgment of line colors and distance in rearview camera. Green line: The distance between the obstacle and the rear of the car is large, and reversing is allowed. Indication: Safe distance. Yellow line: The distance from the rear of the car is 60 cm. Indication: Gradually pay attention to the distance. Red line: The distance from the rear of the car is 30 cm. When the car reaches near this line, the parking space is just right, and no further reversing is allowed. Indication: Warning line. If all lines are blue, the meaning is basically the same as above, with the line closest to the rear being the warning line, indicating to stop reversing. The slightly curved object in the image is the rear bumper of the car.

The reversing camera displays the reversing trajectory lines through the intelligent processing of the vehicle's electronic systems. The rear-mounted camera captures the view behind, while the computer analyzes the steering wheel angle, vehicle speed, and tire position in real-time to predict the reversing path. The curved or straight lines on the screen then appear, helping the driver judge how far they can reverse to avoid obstacles. This system also integrates other sensors, such as radar or ultrasonic probes, to measure the distance from obstacles, with the lines turning red to warn when getting too close. From my experience in car repairs, inaccurate trajectories are often caused by dirt on the camera or software bugs—try wiping the lens with a damp cloth. Higher-end models can even dynamically adjust the lines based on GPS for more precise parking. Overall, it makes reversing much easier, especially in low-light or rainy conditions when visibility is poor, but don’t rely on it entirely—always combine it with checking the rearview mirror for real-time conditions.

I've been driving for over a decade, and the reversing trajectory function is incredibly practical! The camera is installed near the trunk, and as soon as it activates, it transmits images to the screen. The computer calculates the direction based on how much you turn the steering wheel, then overlays colored lines to display the estimated path. The lines curve left or right as you steer, and they become more stable at lower speeds, helping you judge how far you can reverse. Some cars even include distance sensors that change the line color to warn you when you're getting close to an object. Maintenance is simple: keep the camera lens clean and free from mud; check the system settings to ensure the trajectory function is enabled. If the lines stop moving, it might be due to loose wiring or a blown fuse—best to have it checked by a professional. This feature significantly reduces the risk of hitting walls or poles, making parking with kids much more reassuring. Just think about how much more challenging reversing was in the days before cameras!

The reversing trajectory line is a standout feature of vehicle intelligent systems. The rearview camera captures images, while the built-in computer integrates data from the steering wheel sensors to calculate the predicted reversing path in real-time and display it on the screen. For example, when turning the steering wheel to the left, the line curves leftward; the length of the line varies with different vehicle speeds. The system also employs predictive algorithms, taking into account factors like vehicle weight and suspension parameters. During use, engaging the reverse gear immediately displays colored lines and guiding grids on the screen. For maintenance, keeping the camera lens clean to avoid interference is crucial; if the lines appear erratic, it may indicate a faulty wheel speed sensor requiring professional inspection. Many new vehicles combine parking radar to enhance trajectory accuracy, significantly improving parking convenience.
