Claims

[Scope of utility model registration request]

The power is transmitted directly to one of the front and rear wheels, and if necessary, the power is transmitted to the other front and rear wheels by engagement of the transfer clutch. A circuit having a control system that engages the transfer clutch by operating a solenoid valve upon operation, which has an automatic changeover switch for the switch and an accelerator switch that is turned on only when the accelerator pedal is released. A switching control device for a four-wheel drive vehicle, characterized in that the four-wheel drive vehicle is connected in parallel to automatically switch to four-wheel drive when the accelerator pedal is released and the vehicle is decelerating.
