Claims

[Scope of utility model registration request]

In a vehicle control device equipped with an automatic stabilization device that steers the rear wheels in the same wind direction as the front wheels when the front wheels are steered at an angle according to vehicle driving conditions, the automatic stabilization is controlled by a changeover switch and an operation of the changeover switch. A rear wheel position fixing control means stops steering of the rear wheels by the steering device and controls the rear wheels to be fixed in a straight-ahead position, and an automatic stability control device is set to an operating state when the engine key switch is switched from ON to OFF. 1. A vehicle control device comprising: initial control state setting means.
