Method and system for vehicle directional control by commanding lateral acceleration

Abstract

A directional control system for a vehicle includes a driver input device operable to receive a driver input corresponding to a desired lateral acceleration of the vehicle. The system also includes a controller in communication with the driver input device, the controller being operable to generate a control signal in response to comparing the received desired lateral acceleration and an actual lateral acceleration of the vehicle. The system further includes an actuator in communication with the controller, the actuator being operable to effect a change in the direction of travel of the vehicle in response to the control signal.
