Disclosed herein is an electric brake system including: a hydraulic feeder configured to move a piston forward or backward according to a pedal effort from a brake pedal to discharge oil; a motor position sensor configured to measure a position of the piston; and a controller configured to control, when an Anti-lock Brake System (ABS) control starts, a change in direction of the piston based on predicted displacement information of the piston while the ABS control is performed such that the piston is at a target position at target vehicle speed.

[Problem] The present invention provides a vehicle brake system capable of shortening a delay time from time at which an execution request of a pre-crash brake executed by actuation of an electric booster is sent to time at which the pre-crash brake is actually actuated.

[Means for Resolution] In a vehicle brake system (1) including: a hydraulic unit (20); a braking control section (90) for controlling the hydraulic unit (20); a master cylinder (14); an electric booster (10); a booster control section (100) for controlling the electric booster (10); and a pre-crash brake execution determination section (110), the pre-crash brake execution determination section (110) sends information on a specified target value (P_tgt) for decelerating a vehicle to the booster control section (100) and the braking control section (90). When a change amount (ΔP) of the target value (P_tgt) received from the pre-crash brake execution determination section (110) exceeds a specified threshold value (ΔP_thr), the booster control section (100) drives the electric booster (10) prior to a command from the braking control section (90) and executes preceding brake control for generating a specified brake hydraulic pressure to a wheel cylinder.
