TRAILER SWAY MITIGATION USING TORQUE VECTORING
First Claim
1. A system for stabilizing a sway of a trailer attached to a vehicle, the system comprising:
- a controller;
a plurality of sensors in electronic communication with the controller, each of the sensors transmitting sensor data to the controller;
a torque vectoring device in electronic communication with the controller; and
a computer readable memory storing instructions that, when executed by the controller, 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;
determine if the vehicle is traveling in a straight line;
determine a torque distribution signal and transmit it to the torque vectoring device to stabilize the sway of the trailer without braking the vehicle.

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.
