PURPOSE:To reduce the internal circulating torque produced in time of turning as well as to aim at improvements in a rate of fuel consumption, by calculating running torque from a transmission ratio, while installing a controller for a torque limiter. CONSTITUTION:Output of a transmission 6 is transmitted to a differential gear 3b via a torque limiter 7, driving rear wheels 2a and 2b, and the torque limiter 7 secures transmission torque proportional to the exciting current. In addition, size of the exciting current of the torque limiter 7 is calculated by a controller 8 on the basis of an accelerator opening signal out of an engine 5 and a gear position of the transmission 6. A running torque is calculated from this accelerator opening and the gear position of the transmission 6 whereby the exciting current is controlled so as to cause the torque of two-thirds of this torque to become maximum transfer torque of the torque limiter 7.
