HEATING CONTROL METHOD FOR VEHICLE

A vehicle has a battery and an air conditioner heating a vehicle compartment. The vehicle travels by electric power of the battery. An operation mode in which heating of the vehicle compartment is performed includes an outside-air-heat absorption mode in which the vehicle compartment is heated by absorbing heat from outside air without absorbing heat from the battery, and a battery-heat absorption mode in which the vehicle compartment is heated by absorbing heat from at least the battery. The heating control method for the vehicle includes, after an operation of the air conditioner is started in a state where the battery-heat absorption mode is selected, switching from the battery-heat absorption mode to the outside-air-heat absorption mode, or reducing an amount of heat absorbed from the battery in the battery-heat absorption mode, based on a predetermined condition.
