Abstract
An HEV mode and a BEV mode is a hybrid electric vehicle capable of traveling, comprising: a radiator; an air conditioner including a condenser and a pressure sensor for performing air conditioning in a room; a cooling fan that operates in response to the rotation of the engine to blow cooling air to the radiator and the condenser; and a control unit that controls the operation of the engine and the air conditioner, wherein the control unit reduces the amount of heat dissipation of the condenser when the high pressure of the cooler detected by the pressure sensor during traveling in BEV mode becomes equal to or higher than the first pressure.
Claims5
A hybrid electric vehicle configured to travel in a hybrid electric vehicle mode in which the hybrid electric vehicle travels using an engine and a vehicle drive motor and in a battery electric vehicle mode in which the engine is stopped and the hybrid electric vehicle travels using the motor, the hybrid electric vehicle comprising:
- a radiator configured to cool a coolant that circulates inside the engine;
- an air conditioner including a compressor, a condenser configured to condense a refrigerant compressed by the compressor, and a pressure sensor configured to detect a pressure of the refrigerant compressed by the compressor, the air conditioner being configured to condition air in a vehicle cabin;
- a cooling fan configured to operate in response to rotation of the engine to send cooling air to the radiator and the condenser;
- and
- a control unit configured to control operations of the engine and the air conditioner, wherein
- the control unit is configured to reduce an amount of heat dissipation of the condenser when the pressure of the refrigerant detected by the pressure sensor is equal to or higher than a predetermined first pressure during traveling in the battery electric vehicle mode.
