<P>PROBLEM TO BE SOLVED: To provide a vehicle brake system which when generating a brake force by an automatic brake control function, distributes the brake force to a regenerative brake device, thereby having the more improved efficiency in regeneration than before. <P>SOLUTION: The vehicle brake system includes: a hydraulic brake device having a master cylinder, a pump, and a hydraulic control unit; a regenerative brake device; and a brake control device. The brake control device includes: a means for calculating a driver target brake force FT1 corresponding to the manipulation amount of a braking manipulation member; a means for enabling the brake control device itself to set compensation brake forces FD2 for respective wheels separately from the driver target brake force FT2; a means for selecting, for each wheel, larger one of the driver target brake force FT2 and the compensation brake force FD2, and subtracting a base hydraulic brake force FB2 from the selected brake force to set the subtraction result as a compensated target brake force FU2; and a means for controlling the distribution of the compensated target brake force FU2 to a controlled hydraulic brake force FC2 for each wheel and a regenerative brake force FG2 for each driving wheel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
