ABSTRACT:
An object oil temperature is determined by adopting a gradual change process for an oil temperature of a cooling lubricant oil, which is used to lubricate and cool down a motor and a transmission constructed to cause an output power of the motor to be subjected to speed change and to be transmitted to a driveshaft. A load factor of the motor is subsequently set based on the set object oil temperature and a motor coil temperature. A motor torque command is set with the load factor, and the motor is then driven and controlled to ensure output of a torque equivalent to the set motor torque command. This arrangement drives and controls the motor with consideration of the oil temperature of the cooling lubricant oil and thus ensures more adequate actuation of the motor, compared with a conventional drive control without consideration of the oil temperature of the cooling lubricant oil.
