VEHICULAR TEMPERATURE CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a vehicular temperature control device capable of rapidly dropping the in-cabin temperature in an air-cooling mode by an air-conditioner. SOLUTION: The vehicular temperature control device comprises an indoor temperature sensor to detect the in-cabin temperature, a window driving device to drive a window of a vehicle in an elevating/lowering manner, and an air-conditioner capable of setting the target temperature. The window is opened and the outside air is introduced by controlling the window driving device (S350) based on the fact that the temperature difference is larger than the predetermined reference temperature difference ΔTD (15°C) (S320) so that the temperature difference ΔT1 (=TR-TSET) between the in-cabin temperature TR detected by the indoor temperature sensor and the set temperature TSET of the air-conditioner in an air-cooling mode of the air-conditioner reaches the maximum temperature difference between the set temperature TSET of the air-conditioner and the ambient temperature TAM. Thus, by automatically opening the window, the outside air lower in temperature than the in-cabin air is introduced, and the in-cabin temperature can be dropped rapidly. COPYRIGHT: (C)2007,JPO&INPIT
