PROBLEM TO BE SOLVED: To improve control accuracy of a driving control unit for vehicle by accurately setting a steering gear ratio even if it is for a variable gear ratio, as well as eliminating the necessity of preparing individual control units for every steering gear ratio and setting beforehand the steering gear ratio thereon. SOLUTION: A transfer control unit 70 uses a steering gear ratio as one of parameters for calculating clamping torque of a hydraulic multiple disc clutch 21. The transfer control unit 70 then sets by updating the steering gear ratio by assigning a detected steering angle, vehicle speed and yaw velocity to an equation of motion for a vehicle model.
