PROBLEM TO BE SOLVED: To provide a control device for a vehicle which can quickly reduce a forward vehicle speed when the vehicle moves forward in a state that constitution of a reverse range is indicated.SOLUTION: When forward movement of a vehicle in a state that a shift lever is positioned in a R-position (Reverse position) is detected, vehicle speed reduction control is performed. In the vehicle speed reduction control, for example, a brake actuator or the like is controlled, prescribed hydraulic pressure is input to the brake actuator from a brake master cylinder irrespective of an operation of a brake pedal, the hydraulic pressure is distributed to respective brakes, and thus, brake forces are automatically applied to wheels from respective brakes (automatic brake operation). By operations of the automatic brakes, a forward vehicle speed at the automatic brake operation is greatly reduced.SELECTED DRAWING: Figure 3 【課題】後退レンジの構成が指示されている状態で車両が前進している場合に、その前進車速を速やかに低減させることができる、車両用制御装置を提供する。【解決手段】シフトレバーがＲポジションに位置する状態での車両の前進が検出されると、車速低減制御が実行される。車速低減制御では、たとえば、ブレーキアクチュエータなどが制御されて、ブレーキペダルの操作と無関係に、ブレーキマスタシリンダからブレーキアクチュエータに所定の油圧が入力され、その油圧が各ブレーキに分配されることにより、各ブレーキから車輪に制動力が自動的に付与される（自動ブレーキ作動）。自動ブレーキが作動することにより、自動ブレーキ作動時の前進車速が大きく低減する。【選択図】図３
