  • Vehicle drive force control apparatus
    Patent number: 7095196
    Abstract: A vehicle driving force control apparatus is configured to prevent co-rotation of the motor caused by rotation of a pair of wheels when a clutch connecting the wheels and the motor is released (disconnected). When the clutch is released, the motor is braked by short circuiting the armature. The motor is then braked again by setting the field current of the motor to 0 when the rotational speed of the motor reaches 0. After the clutch is released, a braking-direction field current is applied to the motor in accordance with the decreasing rotational speed of the motor such that the braking force is decreased as the rotational speed of the motor decreases.
