Vehicle brake system

A vehicle brake system comprising:

• a hydraulic brake device for applying hydraulic brake force to wheels of a vehicle;
• a regenerative brake device for applying regenerative brake force to drive wheels among the wheels of the vehicle driven by a generator-motor;
• and
• a brake control device for cooperatively controlling the hydraulic brake force of the hydraulic brake device and the regenerative brake force of the regenerative brake device in response to an operation amount of a brake operation member, wherein the brake control device includes;
• a differential amount calculating means for calculating a differential amount by subtracting a regeneration execution brake force obtained by execution of the generator-motor from a regeneration request brake force which is commanded to the generator-motor;
• a regenerative range judging means for judging whether or not the regeneration request brake force is within a range of a re-generable brake force which is executable by the generator-motor;
• and
• a hydraulic pressure restricting means for restricting increase of the hydraulic brake force when the differential amount is judged to be a positive value and the regeneration request brake force is judged to be within the range of the re-generable brake force.
