To provide a vehicle control device which can properly estimate an engagement state of a parking gear and a parking lever.SOLUTION: A vehicle control device 80 controls a vehicle drive system 90. The vehicle drive system 90 includes a main machine motor 70, a rotation angle sensor 75, a parking lock mechanism 30, and an actuator 40. An MG-ECU 82 includes a surface pressure determination part 822, and in the case where an engagement surface pressure is generating, it performs torque assist control for controlling the drive of the main machine motor 70 so as to reduce the engagement surface pressure, when releasing parking lock. The surface pressure determination part 822 determines whether or not an engagement surface pressure is generating in a parking gear 35 and a parking lever 33, based on a detection value of the rotation angle sensor 75 when a surface pressure confirmation torque is applied to the parking gear 35, by the main machine motor 70, in a parking lock state.SELECTED DRAWING: Figure 1 【課題】パーキングギアとパーキングレバーとの噛み合い状態を適切に推定可能な車両制御装置を提供する。【解決手段】車両制御装置８０は、車両駆動システム９０を制御するものであって、車両駆動システム９０は、主機モータ７０と、回転角センサ７５と、パーキングロック機構３０と、アクチュエータ４０と、を備える。ＭＧ－ＥＣＵ８２は、面圧判定部８２２を有し、噛合面圧が発生していると判定された場合、パーキングロックを解除するときに噛合面圧を低減するよう主機モータ７０の駆動を制御するトルクアシスト制御を行う。面圧判定部８２２は、パーキングロック状態にて、主機モータ７０により、パーキングギア３５に面圧確認トルクを印加したときの回転角センサ７５の検出値に基づき、パーキングギア３５とパーキングレバー３３とに噛合面圧が発生しているか否か判定する。【選択図】 図１
