Abstract
A more reliable hydraulic brake device is proposed which is capable of regenerative cooperative control and eliminates wasteful consumption of electric power. In a hydraulic brake device capable of regenerative cooperative control, a hydraulic pressure adjusting device is provided to adjust the hydraulic pressure in the auxiliary hydraulic chamber to a desired value that is above the output hydraulic pressure value of the pressure adjusting valve. During regenerative cooperative control, the output hydraulic pressure of the pressure adjusting valve is supplied to the auxiliary hydraulic chamber as it is. During non-regenerative cooperative control the output hydraulic pressure of the pressure adjusting valve is increased corresponding to regenerative braking force and supplied to the auxiliary hydraulic chamber.
