Abstract
A steering system providing an assist torque to a handwheel is provided, and includes a proportional gain module and a torque command module. The proportional gain module determines a proportional gain value. The proportional gain value is scheduled as a function of a lateral position error and at least one of the following: a near field heading angle, a far field heading angle, a curvature of the lane, and a lateral position of the vehicle. The torque command module determines the torque assist based on the proportional gain value.
