PURPOSE:To restrain occurrence of spins and drifts, by distributing drive force to front and rear wheels among front and rear wheels in accordance with the rotational speeds of the front and rear wheels, the vehicle speed, and the radius of turn. CONSTITUTION:The output shaft of a transmission 22 is coupled to a rear wheel propeller shaft 24R and front wheel propeller shaft 24F through a transfer 23 for changing the distribution ratio of drive force. Meanwhile, an electrical control unit 59 is connected with a front wheel rotational speed sensor 54, a rear wheel rotational speed sensor 55, a means 57 for detecting the speed of the vehicle and a means 58 for detecting the radius of turn corresponding to the steering angle. Further, the transfer 23 is operated in accordance with a control signal from the electrical control unit 59. |
