Abstract: A method for controlling regenerative braking of a hybrid electric vehicle is provided to improve durability of a hydraulic control valve and secure stable braking force when driving the vehicle on a downhill road. A hydraulic electric vehicle generates regenerative braking torque at the start of braking and generates desired braking force by adding hydraulic control braking torque to the generated regenerative braking torque. A method for controlling regenerative braking of the hybrid electric vehicle brakes the vehicle only through hydraulic braking by reducing the regenerative braking torque to zero in case that the maximum regenerative braking torque and the minimum hydraulic control braking torque are generated for a predetermined time.

A brake control apparatus of a hybrid electric car includes a brake switch(1), a brake controlling unit(2), and a recovery brake controlling unit(3). The brake switch senses a driver's brake pedal pushing degree. The brake controlling unit calculates a maximum recovery brake allowable amount and supplies the calculated maximum recovery brake allowable amount to the recovery brake controlling unit. The recovery brake controlling unit determines a recovery brake amount based on a motor generation limit and a battery charging limit to notify the determined recovery brake amount to the brake controlling unit to perform recovery brake control. The brake control apparatus further includes a vibration sensing unit(4) to sense a vibration in a wheel during the brake control and supplies the vibration to the brake controlling unit. The brake controlling unit prevents the vibration from being generated in the brake torque by hydraulic control by expanding a dead zone when the vibration of the recovery brake torque is sensed in the vibration sensing unit.
