<p>PURPOSE:To provide a desired lock torque value regardless of hysteresis generated between a control amount of an operating medium in a differential gear provided in a vehicle and the lock torque value of a clutch. CONSTITUTION:A control unit 4 for controlling an electromagnetic clutch so as to generate a desired lock torque value by adjusting a current value, supplied to the electromagnetic clutch of an electromagnetic control differential gear 1 in accordance with a driving condition of wheels (W1, W2), is provided, and in the case of generating the desired lock torque value by increasing the current value, it is set from a relation between the current value in the case of increasing it and the lock torque value. In the case of generating the desired lock torque value by decreasing the current value, it is set from a relation between the current value in the case of decreasing it and the lock torque value, and a hysteresis corresponding current supply means 43h for controlling a current of this set current value, so that it is supplied to the electromagnetic clutch, is provided in the control unit 4.</p> |
