BRAKING SYSTEM, AND CONTROL METHOD FOR THE BRAKING SYSTEM

摘要

Provided is a braking system (1) comprising a hydraulic brake device (2) for generating a pressure braking force with a wheel cylinder pressure. The hydraulic brake device (2) includes a master cylinder for applying a master cylinder pressure to brake oil in accordance with a manipulation force which is generated when the driver manipulates a brake pedal, a brake booster for aiding the manipulation force by the vacuum established by an internal combustion engine, and a vacuum sensor (23a) for detecting the vacuum of the brake booster. Further comprised is a regenerative braking device (3) for performing a regenerative braking to generate a regenerating braking force. The regenerative braking device (3) generates a higher regenerative braking force than that of the case, in which the detected vacuum is a reference vacuum, in case the detected vacuum is lower than the reference vacuum. The braking system can suppress the uncomfortable feeling of the braking operation by the driver and can improve the mileage.
