Title:
TRAILER SWAY MITIGATION USING TORQUE VECTORING
Document Type and Number:
WIPO Patent Application WO/2012/058259
Kind Code:
A3
Abstract:
A system for stabilizing a sway of a trailer attached to a vehicle. In one embodiment, the system includes a controller, a plurality of sensors in electronic communication with the controller and transmitting sensor data to the controller, a torque vectoring device in electronic communication with the controller, and a computer readable memory storing instructions executed by the controller. The instructions cause the controller to evaluate the sensor data received from the sensors to determine a current vehicle yaw rate, a target vehicle yaw rate, and a yaw rate error of the vehicle. The instructions further cause the controller to determine if the vehicle is traveling in a straight line, to determine a torque distribution signal, and to transmit this signal to the torque vectoring device to stabilize the sway of the trailer without braking the vehicle.
