Patent ID: 8360533

Claim:
A regenerative braking system installed in an electric vehicle, the regenerative braking system comprising: a fuel cell serving as a main power source; a battery serving as an auxiliary power source; a driving motor receiving power from the fuel cell to drive at least one of front and rear wheels; an inverter converting DC voltage supplied from the fuel cell into 3-phase voltage to drive the driving motor and charging the battery with regenerative energy recovered from the driving motor upon braking of the electric vehicle; an EMB (electro-mechanical braking) actuator installed to a rear wheel to generate braking force by operating a caliper using a motor; an EMB ECU controlling an operation of the EMB actuator; and a central ECU controlling the driving motor to perform regenerative braking upon the braking of the electric vehicle, and communicating with the EMB ECU in order to operate the EMB actuator to perform EMB with respect to the rear wheel, wherein the central ECU determines a power of the regenerative braking and a power of the EMB according to a vehicle condition, and controls the power of the EMB in accordance with the power of the regenerative braking.
