BRAKE SYSTEM

A brake system comprises a hydraulic braking device configured to generate a hydraulic braking force; and a regenerative braking device configured to generate a regenerative braking force by an electric motor; wherein the hydraulic braking device comprises a master cylinder configured to generate a hydraulic pressure corresponding to a displacement amount of a brake pedal by discharging a brake oil; a plurality of valves disposed in a flow path connecting a plurality of wheel cylinders and the master cylinder; an accumulator disposed in the flow path; and an electronic control unit (ECU) configured to control the plurality of valves so that the brake oil discharged from the master cylinder is stored in the accumulator, and to transmit a request signal for generating the regenerative braking force to the regenerative braking device.
