Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vehicle control device capable of shortening time required until a temperature control target reaches a target temperature in a vehicle having a temperature control device with a mechanical compressor.SOLUTION: A vehicle ECU 40 is applied to a vehicle including: a transmission 12 for shifting power of an engine 11; and a clutch device 26 that has a mechanical compressor for compressing a refrigerant by using the engine 11 as a power source and drives the compressor when a temperature difference ΔT exceeds a threshold value. The vehicle ECU 40 acquires the temperature difference ΔT, and controls a change gear ratio of the transmission 12 by using engine speed Ne as one condition. The engine speed Ne when the change gear ratio of the transmission 12 is changed is defined as gear change rotational frequency. In this case, when the temperature difference ΔT is the threshold value or less, if the engine speed Ne is reference gear change rotational frequency, the vehicle ECU 40 changes the change gear ratio of the transmission 12. When the temperature difference ΔT is more than the threshold value, the vehicle ECU sets a value higher than the reference gear change rotational frequency as the gear change rotational frequency and changes the change gear ratio of the transmission 12.SELECTED DRAWING: Figure 2 【課題】機械式のコンプレッサーを有する温調装置を備えた車両において、温調対象が目標温度に到達するまでに要する時間を短縮できる車両制御装置を提供する。【解決手段】車両ECU40は、エンジン11の動力を変速する変速機12と、エンジン11を動力源として冷媒を圧縮する機械式のコンプレッサーを有し、温度差ΔTが閾値よりも大きいときにコンプレッサーを駆動するクラッチ装置26とを備えた車両に適用される。車両ECU40は、温度差ΔTを取得するとともにエンジン回転数Neを1つの条件として変速機12の変速比を制御する。車両ECU40は、変速機12の変速比を変更するときのエンジン回転数Neを変速数とすると、温度差ΔTが閾値以下の場合にはエンジン回転数Neが基準変速数であるときに変速機12の変速比を変更し、温度差ΔTが閾値よりも大きい場合には基準変速数よりも高い値を変速数に設定して変速機12の変速比を変更する。【選択図】図2
