PURPOSE: To control the rapid sinking of a brake pedal, the generation of an oil violent sound and a G shock and the like due to stepwise rapid deceleration when a regenerative braking mode is changed over to an ABS mode and at the same time to prevent the braking distance of a vehicle from being extended. CONSTITUTION: This braking device comprises a valve means including relief valves 6, 56 and by-pass valves 7, 53 and the like for controlling the transmission of a hydraulic pressure to a wheel cylinder 5 (Fr) and a wheel cylinder 5 (Rr) from a master cylinder 4 and a skid detection means for detecting the slip ratio of the wheel of a front wheel Fr and/or a rear wheel Rr, and when the slip ratio of not less than a predetermined value is detected by the skid detection means, the regeneration due to regenerative braking is reduced and the operation of regenerative braking is changed over to the operation of hydraulic braking. |
