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