PROBLEM TO BE SOLVED: To provide a control device for a four-wheel drive vehicle, which need not excessively improve the dispersion accuracy of a system configuring component, which need not need a complex system dynamic analysis, and which does not bring the vehicle into an unstable behavior.SOLUTION: For a specified time(T*) from the instant of a zero rise of a command oil pressure (PCMD) or the stepwise change of the command oil pressure (PCMD), the limit of a restriction processing part 542c1 for a feedback control quantity (F/B control quantity) is released, and the feedback control quantity (F/B control quantity) is restricted by a restriction processing part for a time region excepting said specified time (T*). Moreover, the feedback control quantity (F/B control quantity) and the feedforward control quantity (F/F control quantity) are added to determine the driving current of a motor of an oil pump.SELECTED DRAWING: Figure 5
【課題】システム構成部品のバラつき精度を過度に向上させずに済み、複雑なシステム動特性解析を必要とすること無く、かつ、車両を不安全な挙動に陥らせない四輪駆動車両の制御装置を提供する。【解決手段】指令油圧(PCMD)のゼロ立ち上がり時または指令油圧(PCMD)がステップ状に変化した時から規定時間(T*)の間、フィードバック制御量(F/B制御量)に対する制限処理部542c1の制限を解除すると共に、上記規定時間(T*)を除く時間領域においてはフィードバック制御量(F/B制御量)を制限処理部によって制限する。そして、フィードバック制御量(F/B制御量)とフィードフォワード制御量(F/F制御量)とを加算してオイルポンプのモータの駆動電流を決定する。【選択図】図5
