Abstract:
A method and apparatus for controlling a vehicle involves determining if the vehicle is swaying and if the vehicle is swaying, reducing a torque of an engine of the vehicle and/or applying independent braking forces to each wheel of the vehicle. A vehicle for controlling vehicle sway includes an engine, a plurality of wheels, a braking system configured to apply independent braking forces to each wheel, and a controller configured to control the engine and the braking system. The controller is configured to determine a correlation coefficient in accordance with any phase shift occurring between a yaw acceleration signal and a lateral acceleration signal. The correlation coefficient is compared to a threshold value to determine whether the vehicle is swaying. If the vehicle is swaying, the controller causes a torque of the engine to be reduced and/or braking forces to be applied independently to each wheel.
