PURPOSE:To prevent the generation of swerve phenomenon by installing a revolution speed difference detecting means for wheels and road surface frictional coefficient detecting means and increasing the clutch fastening force according to the revolution speed difference and increasing the fastening force by the portion of increase of the clutch fastening force corresponding to the car speed on a road having a low frictional coefficient. CONSTITUTION:A clutch control means 4 receives the signals supplied from a revolution speed difference detecting means 301 and a road surface friction coefficient detecting means 302 and calculates the revolution speed difference between the front and rear wheels. In the region exceeding a prescribed revolution speed difference, an instruction signal for sharply increasing the transmission torque to the front wheel side is outputted into a clutch means 2. During the traveling on a road having a low frictional coefficient, an instruction signal for the addition by the increase portion of the transmisson torque corresponding to the car speed is outputted. Therefore, in the acceleration form the traveling on the road having a low frictional coefficient, the straight advance stability is improved, and generation of swerve phenomenon car be prevented.
