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.
