STABILITY CONTROL SYSTEM WITH BODY-FORCE-DISTURBANCE HEADING CORRECTION
A yaw stability control system for a vehicle detects and eliminates the vehicle yaw angle resulting from a body-force-disturbance and returns the vehicle to a pre disturbance heading. A yaw rate module generates a signal indicative of the vehicle yaw rate error. A yaw angle error module is triggered in response to a body-force-disturbance being detected by a body-force-disturbance detection unit, and performs integrations of the yaw rate signals to calculate a yaw angle error in order to obtain a correction of the vehicle yaw angle resulting from the body-force-disturbance. A yaw control module uses the yaw angle error in combination with the yaw rate error for a limited time period to generate yaw control signals that are sent to the vehicle brakes and/or active steering system for performing vehicle yaw stability control operations a signal to perform a body-force-disturbance yaw stability control operation for.
