Abstract:
1. An apparatus for controlling vehicle stability comprising: a yaw rate sensor detecting a yaw rate and outputting a corresponding yaw rate signal; a pressure calculator calculating a calculated brake pressure for controlling respective wheels on the basis of a yaw rate signal input from the yaw rate sensor and signals input from a steering angle sensor, a lateral acceleration sensor, a vehicle speed sensor, and a master brake pressure sensor; an adder adding a target brake pressure and the calculated brake pressure; a pressure controller outputting a PWM signal for controlling a brake pressure supplied to the respective wheels by analyzing a pressure value calculated by the adder and information of a steering angle, a lateral acceleration, and a vehicle speed; and an oil pressure controller controlling the brake pressure by calculating an actual brake pressure on the basis of the PWM signal transmitted from the pressure controller by utilizing a predetermined non-linear map, a linear model, and a disturbance compensating map.
