PROBLEM TO BE SOLVED: To provide a control device for a vehicle which can secure start responsiveness required by a user while suppressing an incongruity of the user caused by the generation of noise when gradually lowering the working fluid pressure of a brake at the release of a brake operation under a prescribed condition.SOLUTION: A control device for a vehicle comprises: a hydraulic brake device: a control part for releasing a brake force of the vehicle by gradually lowering the working fluid pressure of the brake device irrespective of an operation of the brake device when the operation of the brake device is released under a prescribed condition; a first determination part for determining a requirement degree with respect to the start responsiveness of a user on the basis of a vehicle state; and a second determination part for determining an allowable degree with respect to noise on the basis of at least either of the vehicle state and a peripheral state of the vehicle. When an accelerator is operated after the release of the operation of the brake device under the prescribed condition up to a finish of the release of a brake force of the vehicle, the control part decides a decompression speed on the basis of the allowable degree and the requirement degree.SELECTED DRAWING: Figure 2
【課題】所定の条件下におけるブレーキ操作の解除に際して、ブレーキの作動液圧を漸減させる場合に、異音の発生によるユーザの不快感を抑制しつつ、ユーザの要求する発進応答性を確保することが可能な車両用制御装置を提供すること。【解決手段】油圧式のブレーキ装置と、所定の条件下でブレーキ装置の操作が解除された場合、ブレーキ装置の操作とは無関係に、ブレーキ装置の作動液圧を所定の減圧速度で漸減させて、車両の制動力を解除する制御部と、車両状態に基づき、ユーザの発進応答性に対する要求度を判断する第1判断部と、車両状態及び車両の周辺状態の少なくとも一方に基づき、異音に対するユーザの許容度を判断する第2判断部と、を備え、制御部は、所定の条件下でブレーキ装置の操作が解除された後、車両の制動力の解除が完了するまでの間で、アクセル操作がされている場合、許容度及び要求度に基づき、減圧速度を決定する。【選択図】図2
