[0002] The statements in this section merely refer to the background art related to this invention and do not necessarily constitute prior art.

[0003] When a vehicle is being washed using an automatic car wash, the driver first needs to drive the front wheels onto the conveyor belt, put the vehicle in neutral, fold the side mirrors, and turn off the engine. The vehicle then enters the washing area under the influence of the conveyor belt. After the wash is complete, the driver follows the on-screen instructions to start the vehicle, open the side mirrors, put it in drive, and drive out of the washing area.

[0004] During the above process, the driver must carefully maneuver the vehicle to enter the conveyor belt guide trough; otherwise, they may face the embarrassment of having to adjust and re-enter multiple times. Furthermore, because the vehicle needs to be operated multiple times before and after washing, the driver must remain in the driver's seat throughout the process, restricting their freedom of movement.
