For example, a tire having a long distance from the current position to a target position may be rotationally driven at a higher rotational speed than a tire having a short distance.
- step S9 After passing through step S9, the process returns to step S1 and steps S1 to S9 are repeated until the vehicle 100 returns to the traveling route. That is, the processing device 17 updates the return position every moment until the vehicle 100 deviating from the travel route returns to the travel route (step S5), thereby setting the steering angles of the tires 11 to 14 every moment.
