<P>PROBLEM TO BE SOLVED: To restrain the occurrence of vibration in an electric motor or its mounting base when disturbance smaller than a control time constant of the electric motor is applied by extending an operating range utilizing the electric power of the electric motor, and to prevent the occurrence of over-current in switching the driving state of a second axle by the electric power of the electric motor to the non-drive state. <P>SOLUTION: In controlling the stop of the electric motor 12, while field current of the electric motor 12 is lowered by an electric motor field current control means 32, an armature current of the electric motor 12 is controlled by an electric motor armature current control means 33, and in the timing when a torque difference between a rear wheel axle 9 and the electric motor 12 is substantially zero in an electromagnetic clutch 14, the electromagnetic clutch 14 is controlled to open to intercept the transmission of the driving force from the electric motor 12 to the rear wheel axle 9. <P>COPYRIGHT: (C)2008,JPO&INPIT |
