Abstract
A vehicle includes: a battery; a thermal management system; and an ECU. The thermal management system includes an electric pump that circulates a heat medium that exchanges heat with the battery. The thermal management system performs thermal management in the vehicle. When a temperature of the battery is raised using the thermal management system, ECU controls the electric pump such that a noise caused by driving of the electric pump is suppressed when there is no background noise as compared with when there is a background noise, the background noise being a noise caused by a device other than the electric pump.
Claims11
A vehicle comprising:
- a battery;
- a thermal management system that performs thermal management in the vehicle, the thermal management system including a pump that circulates a heat medium that exchanges heat with the battery;
- and
- a controller that controls the thermal management system, wherein
- when a temperature of the battery is raised using the thermal management system, the controller controls the pump such that a pump noise is suppressed when a prescribed condition indicating that a background noise is small is satisfied as compared with when the prescribed condition is not satisfied, the pump noise being a noise caused by driving of the pump, the background noise being a noise caused by a device other than the pump.
A controller of a vehicle having a thermal management system mounted thereon, the thermal management system including a pump that circulates a heat medium that exchanges heat with a battery, the controller comprising a processor, wherein
- when a temperature of the battery is raised using the thermal management system, the processor suppresses a pump noise when a prescribed condition indicating that a background noise is small is satisfied as compared with when the prescribed condition is not satisfied, the pump noise being a noise caused by driving of the pump, the background noise being a noise caused by a device other than the pump.
A control method for a vehicle having a thermal management system mounted thereon, the thermal management system including a pump that circulates a heat medium that exchanges heat with a battery, the control method comprising
- raising a temperature of the battery using the thermal management system, wherein
- the raising includes suppressing a pump noise when a prescribed condition indicating that a background noise is small is satisfied as compared with when the prescribed condition is not satisfied, the pump noise being a noise caused by driving of the pump, the background noise being a noise caused by a device other than the pump.
