Abstract
Methods and systems for generating haptic feel torque for a steering system for an automotive vehicle are provided. In an exemplary embodiment, a method for generating haptic feel torque for a steering system for an automotive vehicle includes inputting a steering command signal by manipulating a steering wheel mounted to a steering column of the automotive vehicle. In response to the steering command, the method includes changing an orientation of road wheels of the automotive vehicle. Also, the method includes communicating condition data of the road wheels to a controller. Further, the method includes calculating with the controller a turning acceleration of the steering column in response to changing the orientation of the road wheels by modeling a virtual spring and a virtual damper interconnected between the steering column and the road wheels based on the condition data. The method also includes applying the turning acceleration to the steering column.
