What are the requirements for installing dynamic reversing trajectory?
2 Answers
Dynamic reversing trajectory installation requirements: Self-installed reversing cameras can only achieve static trajectories. Dynamic trajectories require data collection of steering wheel angles, which necessitates signals from the CAN bus or an angle sensor. Dynamic trajectory lines: These change with the rotation of the steering wheel, indicating the area the rear of the car will pass through when reversing in the current wheel direction. The trajectory lines adjust according to the wheel direction; when the wheels are straight, the trajectory lines align with the positioning area. When the driver operates the car in reverse, the intelligent trajectory reversing system displays two reversing guide lines on the DVD reversing camera, representing the movement path of the rear wheels. As the steering wheel turns, the reversing trajectory lines rotate accordingly, accurately planning the reversing path.
To install a dynamic reversing trajectory system, first confirm if the vehicle is compatible with OEM or aftermarket reversing cameras. If the car lacks a matching system, you may need to purchase a new camera model with trajectory functionality. Hardware preparation for installation includes checking if the camera is dustproof and waterproof, meets automotive standards, and ensuring the infotainment system supports software integration; otherwise, the screen may require an upgrade or reprogramming. During the process, I recommend hiring a skilled technician or professional shop to use tools like a multimeter to calibrate the trajectory lines to synchronize with steering wheel movements, preventing misalignment during reversing. Costs range from a few hundred to over a thousand yuan, so budget for installation fees and spare parts. Safety testing is essential—conduct multiple reversing tests post-installation to verify trajectory accuracy.
