PROBLEM TO BE SOLVED: To provide a climate control device for a vehicle capable of reducing dark current, and improving accuracy of an obtained ambient temperature outside the vehicle, thus raising suitability of control of temperature inside a cabin.SOLUTION: The climate control device for a vehicle includes: ambient temperature measuring means 2 for measuring an ambient temperature value outside the vehicle; storage means 3 for storing an ambient temperature value upon stopping, measured by the ambient temperature measuring means 2 when an engine is stopped; and a timer 4 that is actuated while the engine is stopped. When the engine is stopped while communication is established between an air conditioner ECU 5 and a timer ECU 6, a count value of the timer 4 is cleared. After the engine is restarted while the communication is established, the following determination and process are performed. If the count value of the timer 4 is below a predetermined value, the ambient temperature value upon stopping stored in the storage means 3 is used as an ambient temperature value for climate control, to perform climate control inside a cabin. If the count value of the timer 4 is equal to or above the predetermined value, an ambient temperature value measured at that time is used as the ambient temperature value for climate control.SELECTED DRAWING: Figure 2
【課題】 暗電流を低減させるとともに、車両の外気温をより正確に取得することができ、よって車室内温度をより好適に調節可能となる車両用空調制御装置を提供する。【解決手段】 車両の外気温値を計測する外気温計測手段2と、外気温計測手段2によってエンジン停止時に計測された停止時外気温値を記憶する記憶手段3と、エンジン停止状態において作動するタイマ4とを備え、タイマ4は、エアコンECU5とタイマECU6との間の通信が確立されている状態でエンジンが停止した時に、カウント値がクリアされ、エンジン再始動状態で前記通信が確立されている状態において、タイマ4のカウント値が所定値未満の場合、記憶手段3に記憶された前記停止時外気温値を車室内の空調制御に用いる空調制御用外気温値として使用し、タイマ4のカウント値が前記所定値以上の場合、その時点で計測される外気温値を前記空調制御用外気温値として使用する。【選択図】 図2
