Abstract
A method and apparatus for controlling transmission oil temperature are provided. The transmission oil is heated using a motor coil of an electric oil pump (EOP) as a heater before a startup of a vehicle. The method includes applying a current to the motor coil of the EOP configured to operate a transmission of the vehicle to thus heat the transmission oil by heat generated from the motor coil.
Claims12
A method for controlling a temperature of transmission oil of a vehicle, comprising:
- applying, by a controller, a current to a motor coil of an electric oil pump (EOP) configured to operate a transmission of the vehicle to heat transmission oil by heat generated from the motor coil,
- wherein the current is applied to the motor coil before the vehicle is started when a door lock release signal is received.
An apparatus for controlling transmission oil temperature, comprising:
- an electric oil pump (EOP) configured to operate a transmission for a vehicle;
- and
- a transmission control unit (TCU) configured to operate the EOP,
- wherein the TCU is configured to apply a current to a motor coil of the EOP to heat the transmission oil by heat generated from the motor coil and
- the TCU is configured to commence applying the current to the motor coil when a door lock release signal is received.
