Abstract
The present disclosure relates to a cooling system and method of a HEV for cooling an engine clutch and a motor in a HEV, and includes an EOP for pumping oil from an oil pan, a flow regulating valve for adjusting a coolant amount supplied to an engine clutch and a motor in the EOP, and a controller that determines whether to adjust a coolant amount based on a temperature of the engine clutch and a temperature of the motor, accelerates a motor of the EOP based on at least one of an ATF temperature, an engine clutch temperature, a motor temperature, or a TMM control mode, and controls the flow regulating valve depending on a motor speed of the EOP to adjust the coolant amount supplied to from the EOP the engine clutch and the motor.
Claims20
A cooling system of a hybrid electric vehicle (HEV), the system comprising:
- an electronic oil pump (EOP) configured to pump oil from an oil pan;
- a flow regulating valve configured to adjust a coolant amount supplied to an engine clutch and a motor in the EOP;
- and
- a controller configured to:
- determine whether to adjust a coolant amount based on a temperature of the engine clutch and a temperature of the motor;
- accelerate a motor of the EOP based on at least one of an automatic transmission fluid (ATF) temperature, an engine clutch temperature, a motor temperature, or a temperature management module (TMM) control mode;
- and
- control the flow regulating valve depending on a motor speed of the EOP to adjust the coolant amount supplied from the EOP to the engine clutch and the motor.
A cooling method of a hybrid electric vehicle (HEV), the method comprising;
- determining, by a controller, whether to adjust a coolant amount, based on a temperature of an engine clutch and a temperature of a motor;
- accelerating a motor of an EOP based on at least one of an ATF temperature, an engine clutch temperature, a motor temperature, or a TMM control mode when it is determined that the coolant amount is adjusted;
- and
- controlling a flow regulating valve depending on a motor speed of the EOP to adjust the coolant amount supplied from the EOP to the engine clutch and the motor.
