To improve accuracy of a control of matching an engaging force of an electromagnetic clutch to a target engaging force.
An actual exciting current Ia flowing in electromagnetic clutches CL and CR is detected by a current detecting means Sb, a target engaging force T of the electromagnetic clutches is calculated by a target engaging force calculating means M1, a target existing current I of the electromagnetic clutches is calculated by a target existing current calculating means M2 on the basis of the target engaging force T, and the engaging force of the electromagnetic clutches is subjected to feedback control by a current feedback control means M3 on the basis of a deviation of the target existing current I and the actual exciting current Ia. Since a load applied to frictional engaging members of the electromagnetic clutches is detected by a load detecting means Sa, an actual engaging force Ts of the electromagnetic clutches is calculated by an actual engaging force calculating means M5 on the basis of the load, and the target exciting current I is corrected by a target exciting current correcting means M6 on the basis of the actual engaging force Ts, the accuracy of the control of matching the actual engaging force Ts of the electromagnetic clutches to the target engaging force T can be improved.
