Abstract
A system and method for vehicle dynamic control processes a compensated yaw rate signal measurement and a compensated lateral acceleration signal measurement (30, 32) to derive a signal measurement of road bank angle disturbance not compensated for in a compensated steering angle signal measurement and provides the derived signal to a controller (12). The compensated steering angle signal measurement is an input to the controller. Because a disturbance already compensated in the compensated steering angle signal measurement is transparent to the controller, the controller is able to adjust the control action of the vehicle dynamic control system based on the derived signal measurement of road bank angle disturbance not compensated for in a compensated steering angle signal measurement, thereby providing enhanced robustness of control.
