Abstract:
Electric power steering systems and a method for controlling an electric power steering system are provided. The method, for example, includes, but is not limited to, determining, by a controller, a speed of a vehicle based upon data from a sensor, and adjusting, by the controller, a stiffness of an isolator in an electric power steering system via at least one piezoelectric device embedded in the isolator based upon the determined speed of the vehicle.
