Steering system clatter mitigation

摘要

A steering system clatter mitigation apparatus and method. The clatter mitigation apparatus excites the steering system at a frequency within a range of an existing engine noise. The excitation of the steering system at a different frequency than the clatter sound greatly reduces the clatter sound. The sound produced by the excitation of the steering system is masked by the existing sound of the engine.

主权项

1. An audible clatter mitigation apparatus for a steering system of a vehicle, the apparatus comprising:
an actuator connected to the steering system; and a controller programmed to actuate the actuator at a sinusoidal frequency that is a function of a steering rack motor torque and an engine noise frequency, causing steering system components and gear sets associated therewith to excite at a frequency within that of an engine noise frequency range.
