VEHICULAR AIR-CONDITIONING CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To lower the power consumption of air conditioners in vehicle travel without degrading the cooling and heating effects of pre-air-conditioning for an occupant riding action. SOLUTION: While a pre-air-conditioning request switch is on, power from an external power source 75 that is charging a secondary battery 73 is used to operate an inverter 46 of a pre-air conditioner 1 so that the vehicle interior is preliminarily cooled or heated during the charging operation. For a given time from the removal of the external power source 75 from the vehicle after the charging operation of the secondary battery 73 to the vehicle driveaway state when the occupant having got into the vehicle starts to drive it, power from the secondary battery 73 is used to continue operating the inverter 46 of the pre-air conditioner 1 so that the vehicle interior is cooled or heated preliminarily even after the disconnection of the external power source 75.
