Active aerodynamic vehicle stability assist control system and control method

The present invention relates to an active vehicle stability control system of the power assist control air, an effect of the auxiliary and aerodynamic vehicle body yaw moment of couple in aerodynamic method. When the vehicle speed is greater than or equal to 80Km / h running, driving stability control system is determined according to the intention of the driver steering wheel angle input by the driver, accelerator pedal position, and the brake master cylinder pressure signal, and according to the yaw angular velocity, lateral acceleration, the vehicle is determined real driving conditions, by adjusting the opening degree of the wind sail actively change the active left of the vehicle, the difference between the air resistance of the right frontal area generated directly constitute auxiliary pneumatic yaw moment of couple, by simultaneously left and right sides of the vehicle driving force control braking to steer the vehicle, running condition of the vehicle as close to the driving intention of the driver.
