The present invention relates to a system and a method to control the posture of a hybrid vehicle using regenerative braking capable of correcting the posture of the vehicle by decreasing or increasing the regenerative braking force of the vehicle when the posture of the vehicle is unstable. According to an embodiment of the present invention, the method to control the posture of the hybrid vehicle comprises: a step of calculating a yaw rate when receiving information on the driving state of the hybrid vehicle; a step of determining whether the hybrid vehicle tends to oversteer or understeer by comparing between a yaw rate threshold and a delta yaw rate calculated based on the calculated yaw rate and a yaw rate measured by a yaw rate sensor; a step of receiving a signal in accordance to an amount of brake pedal manipulation of a driver, and determining the regenerative braking force and a hydraulic braking force respectively in order to satisfy a driver braking force calculated based on the signal when the hybrid vehicle is determined to have a tendency to oversteer or understeer in the above determination step; and a step of braking the hybrid vehicle when adding or subtracting an additional regenerative braking force in accordance to the delta yaw rate to or from the determined regenerative braking force. |
