Abstract

A control system for a steering system is provided, and includes an acceleration module, a scaling module, and a final command module. The acceleration module determines a hand wheel acceleration. The scaling module determines a rejection command. The rejection command is based on the hand wheel acceleration and a road wheel frequency. The final command module determines an adjusted assist command that is based on a normal assist command and the rejection command.
