[0027] The second PCB board 10 can be used as a button control board, and the first PCB board 9 can be used as a motor control board.

[0028] When the simulator is installed, connect the USB interface 16, the external power supply port 17 to the motor control plate with corresponding wires, then fix the base 4 by the base 4 mounting holes so that the simulator will not loosen and shake.

[0029] When the simulator is running, the user can set the parameters of the simulator through the button control plate arranged in the second cavity 8, and then control the steering wheel 5 to drive the shell rotor 1. The steering wheel 5 gives feedback to the user, so that the user can feel the experience of controlling the car in person.
