PROBLEM TO BE SOLVED: To prevent dragging feeling of a brake from being given to a driver in completion of brake assist control. SOLUTION: In completion processing of the brake assist control, a brake liquid is returned to a regulator RG through a conduit MR, and the brake liquid is returned to a master cylinder MC through a conduit MF. Thereby, the brake liquid used for boosting a liquid pressure of a bulk-up amount can be quickly returned, and the brake liquid pressure applied to respective wheel cylinders Wfr-Wrl can quickly approach M/C pressure inherently generated. Accordingly, in completion of brake assist control, the dragging feeling of the brake can be prevented from being given to the driver. COPYRIGHT: (C)2009,JPO&INPIT
