POWERTRAIN, CONTROL APPARATUS AND MOTOR CONTROL UNIT

A powertrain, a control apparatus, and a motor control unit. The powertrain includes a drive motor and a transmission device. The transmission device disconnects a transmission connection between the drive motor and a wheel based on a result of a comparison between a temperature or a viscosity of a lube oil and a preset parameter value, and a rotational speed of the drive motor varies with the result of the comparison between the temperature or the viscosity of the lube oil and the preset parameter value. The drive motor stirs the lube oil through idling, to make the temperature of the lube oil rise rapidly. The powertrain, the control apparatus and the motor control unit provided can improve fluidity of the lube oil at very low temperatures, so that a lube oil pump can be started smoothly.
