PROBLEM TO BE SOLVED: To realize miniaturization of an electric motor and a generator in an electric motor drive force assisting vehicle. SOLUTION: When a slip of a front wheel is judged in a rear wheel assist control judging circuit 13c, an alternator 6 is connected to a motor side from a battery side by switching a changeover switch 8, and motor power and an engine speed are calculated by a rear wheel assist control circuit 13e, in accordance therewith, the engine speed is increased, a motor current can be increased, and increasing of a speed of the front wheel is suppressed through a brake actuator 12 by a TCS control circuit 13b. Since large assist force by a rear wheel can be generated while increasing of a speed of the front wheel is suppressed, electric motor drive force assist control can be performed without enlarging size of a generator and a motor. |
