Abstract:
A method to reduce vehicular sensitivity to torsional smooth road shake (SRS) at the steering wheel provided by selectively increasing reverse driven-impedance of the steering system via an effective dynamic tuned vibration absorber comprising the existing power steering motor inertia supported on the torsional stiffness of the gearing to the rack in the case of a REPS system, or of the column rotary shaft in the case of a CEPS system.
