Steering wheel controller: The torsion bar connected to the steering wheel can be driven to rotate the steering wheel by the upper signal;
Stepping controller: Connected to the accelerator or brake, it can be driven to press down by the upper signal;
Gear controller: Connect the gear shift and drive it to different positions by the upper signal.
We need to simulate the driver's driving actions as an automated agent, and the steering wheel, pedals, and gears are all ready-made in the car.
