Abstract
A low temperature drive control device is used for a motor mounted automotive vehicle in which the rotation of a motor is transmitted to a wheel and a common oil is used for cooling the motor and also for lubricating gears. The motor mounted automotive vehicle includes a command torque calculator for calculating a command torque to be applied to the motor in dependence on an acceleration input, a motor drive controller for controlling an electric current value to be supplied to the motor in dependence on the command torque calculated by the command torque calculator an oil temperature detector for detecting the oil temperature, and a motor torque changer for changing the command torque in dependence on the oil temperature detected by the oil temperature detector.
