  • Patent number: 11965468
    Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.

  • Patent number: 7140427
    Abstract: In a vehicle air conditioner for heating a passenger compartment by a heater core and a heat pump cycle, when operation of a heat pump cycle is switched from a defrosting operation to a heating assist operation, a heating degree of the heater core is increased higher than a predetermined heating degree. Further, when the operation of the heat pump cycle is switched from the defrosting operation to the heating assist operation, an air outlet mode except for a defrosting mode for defrosting a windshield is set. Further, in the defrosting operation of the heat pump cycle, the temperature of an interior heat exchanger of the heat pump cycle is set higher.

  • Patent number: 7013659
    Abstract: In a battery cooling system that cools a battery by using conditioned air (inside air of a passenger compartment) of a vehicle air conditioner, a battery control unit controls a battery blower to increase an air amount supplied to the battery when a predetermined condition is satisfied. In contrast, an air-conditioning control unit decreases a compression capacity of a compression device after an air amount supplied to the battery is increased to a predetermined amount by the battery control unit. For example, the air-conditioning control unit decreases the compression capacity of the compression device after a predetermined time passes after the air amount supplied to the battery is increased to the predetermined amount. Accordingly, the temperature inside the passenger compartment and the compression device can be stably controlled.

  • Patent number: 6978628
    Abstract: When a preset protection temperature is exceeded, an air conditioning device for a vehicle equipped with air conditioner inverter protection means works to lower the output of the air conditioner inverter. This lowers the output of the air conditioner inverter, whereby heat is released in decreased amounts from the coolant through a first heat exchanger suppressing a rise in the temperature of the EV cooling water.
