VEHICLE AIR-CONDITIONING METHOD AND VEHICLE AIR-CONDITIONING DEVICE

A vehicle air-conditioning device includes: an air-conditioning device having an all-seat air-conditioning mode in which air-conditioned air is blown out to occupants of all seats in a vehicle cabin and an individual air-conditioning mode in which the air-conditioned air is blown out to some of the occupants of all seats; a selection device used to select the all-seat air-conditioning mode and the individual air-conditioning mode; and a controller configured to control the air-conditioning device in an air-conditioning mode selected in the selection device. When the vehicle is activated by a remote starter device configured to remotely activate the vehicle, the controller controls the air-conditioning device by switching the air-conditioning mode to the all-seat air-conditioning mode even when the air-conditioning mode selected at previous turning-off of an ignition device is the individual air-conditioning mode.
