摘要
A system and method for determining a frequency response of a power steering system is disclosed including a steering assist motor configured to generate an assist torque about an axis of a steering shaft when activated. The method includes monitoring, by a controller, a torque transducer that measures a steering output torque of the steering shaft experienced during a first frequency sweep and a second frequency sweep. The method also includes determining, by the controller, a transfer function based on the steering output torque monitored during the first frequency sweep and the second frequency sweep, where the transfer function indicates the response by the power steering system.
