Abstract:
1. A vehicle brake device comprising: a hydraulic brake device which adjustably applies a hydraulic pressure braking force to vehicle wheels; a regeneration brake device which applies a regeneration braking force to a drive wheel of the vehicle wheels driven by a generator/motor; a brake control device including a target obtaining means for obtaining a target braking force corresponding to an operating amount of a brake operating member, a cooperative control means for cooperatively controlling the hydraulic brake device and the regeneration brake device to have a total braking force, which is a sum of the hydraulic pressure braking force and the regeneration braking force, become equal to the target braking force and an anti-lock brake control means for prohibiting a generation of the regeneration braking force by stopping the operation of the cooperative control means when the cooperative control means is in operation and a locking tendency is shown at the one of the vehicle wheels and suppressing a generation of locking at the one of the vehicle wheels by adjusting the hydraulic pressure braking force, wherein the brake control device further includes a minimum value calculating means that observes and memorizes a minimum value of the target braking force during an ABS control operation operated within one braking operation and sets the minimum value as the regeneration allowing braking force which is used after the completion of the ABS control operation such that after the cooperative control is restarted within the one braking operation a regeneration allowing means allows the generation of the regeneration braking force only when the target braking force is less than a value of the regeneration allowing braking force.
