PURPOSE:To simplify control and improve stability, etc. by judging plural traveling modes such as an urban district traveling, a mountain road traveling, a suburbs traveling, a freeway traveling, etc. from a traveling condition for a defined period of time and controlling the torque distribution of front and rear wheels for each of said traveling modes. CONSTITUTION:In a control unit 42, a means value is obtained by each of a mean vehicle speed detectig part 50 into which the vehicle speed V of a vehicle sensor 41 is inputted and a means steering quantity detecting part 51 into which the steering quantity theta of a steering angle sensor 46 is inputted. And, a mean vehicle speed Vm and a means steering quantity thetam are inputted into a traveling mode judging part 52 and, from the relation between both, various traveling mode parts 53a-53d are judged and a torque distribution ratio alpha (TF/TR) is determined by various torque distribution setting parts 54a-54d. Also, the various torque distribution signals are inputted into a power flow switchover part 55, which outputs an operation signal to an actuator 44. Further, the various torque distribution signals, together with an input torque Ti and a vehicle speed V, are inputted into a clutch torque control part 56, which outputs a defined clutch hydraulic pressure signal to an actuator 43.
