Abstract: An object of the present invention is to provide a controller for an electric four-wheel-drive vehicle, which is capable of minimizing torque changes and consuming excessive power even when the excessive power is generated by a generator. A motor control unit causes an AC motor to generate desired torque by controlling an inverter. When the power generated by the generator exceeds the power consumed by the inverter and AC motor to generate excessive power, a current command determination unit in the motor control unit consumes the excessive power by increasing a loss in the AC motor.

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.

Abstract: A control device for controlling a motor of an electrical vehicle is provided with a motor control circuit 7 having a first calculation control circuit 11 and a second calculation control circuit 12. In operation, the motor control circuit 7 allows the first and second calculation control circuits 11, 12 to respectively calculate motor control commands It*, Im* and Its*, Ims* on the basis of inputted identical driving condition. The circuit 7 compares the motor control commands It*, Im* calculated by the first calculation control circuit 11 with the motor control commands Its*, Ims* by the second calculation control circuit 12, respectively. When a difference between the calculated commands It* and Its* and another difference between the calculated commands Im* and Ims* are equal to or more than a predetermined value, then the motor control circuit 7 outputs a stop command to stop an operation of the motor.

Abstract: An inverter main circuit has a DC link capacitor for driving a motor with a power of a battery. An inverter relay is arranged to feed a power of the battery to the inverter main circuit. An auxiliary relay is arranged to feed a power of the battery to the inverter main circuit through a resistor. A main key switch connects the battery to the inverter main circuit through the inverter and auxiliary relays when assuming ON, causing the motor to serve as a generator to charge the DC link capacitor when assuming OFF. When, upon turning the main key switch ON, a speed sensor senses that the rotation speed of the motor is within a predetermined range, a control unit turns the auxiliary relay ON, then the inverter relay ON after shorting armature coils of the motor with the aid of the inverter main circuit and then stops the shorting of the armature coils with the aid of the inverter main circuit.
