Abstract
Methods and systems are provided for controlling a steering system of a vehicle is provided. A detection unit is configured to obtain one or more of the following values: a compass heading, a global positioning system (GPS) heading, a yaw velocity, and a difference in tire angular velocities. A processor is coupled to the detection unit, and is configured to determine whether a vehicle is on a straight line path using one or more of the compass heading, the GPS heading, the yaw velocity, and the difference in tire angular velocities, activate the steering system if it is determined that the vehicle is on a straight line path, and disable the feature of the steering system if it is determined that the vehicle is not on a straight line path.
