Abstract
A starting assistance device for a vehicle has an electric motor and a dog clutch which is switched on at the time of starting of the vehicle to thereby transmit a torque to idler wheels. A sensor is provided to detect the switching on and switching off of the dog clutch. In case the switching off of the dog clutch is not detected when the rotational speeds of the idler wheels have exceeded a predetermined value after the starting of the vehicle, the electric motor is driven in such a direction of rotation so as to cancel the torque which operates on the dog clutch due to the frictional force in the electric motor.
