Abstract
According to one or more embodiments of the technical solutions described herein, a method for generating torque in a steering system includes computing, by a controller, a lateral velocity of a vehicle using a vehicle model that uses a vehicle velocity, a surface friction estimate, a tire-angle, and at least one of a measured yaw rate from a yaw rate sensor and a lateral acceleration. The method further includes generating, by the controller, a torque command for providing assist torque to a driver, the torque command is based on the lateral velocity that is computed. The method further includes providing, by a motor, the assist torque, which is an amount of torque corresponding to the torque command.
