Claim 0:
1. A regenerative braking control device for a vehicle, the regenerative braking control device comprising:
a front wheel power train including first elements of an engine, a front wheel motor, an engine clutch mounted between the engine and the front wheel motor, a hybrid starter generator (HSG) connected to the engine to start the engine, and a transmission for shifting power of the engine and the front wheel motor to output the shifted power to a front wheel of the vehicle;
a rear wheel power train including second elements of a rear wheel motor, and a reducer for reducing power of the rear wheel motor to output the reduced power to a rear wheel of the vehicle;
a battery connected to the front wheel motor, the rear wheel motor, and the hybrid starter generator to be chargeable and dischargeable; and
a control unit connected to the front wheel power train and the rear wheel power train, wherein the control unit is configured for distributing a rear wheel regenerative braking required amount to the rear wheel motor while braking is started, by controlling at least one of the first elements of the front wheel power train and the second elements of the rear wheel power train, and configured for distributing a front wheel regenerative braking required amount to the front wheel motor by controlling at least one of the first elements of the front wheel power train and the second elements of the rear wheel power train upon determining that a slip of the rear wheel will occur according to a speed difference between the front wheel and the rear wheel.
