Road wheel disturbance rejection based on hand wheel acceleration

摘要

A control system for a steering system (12) is provided, and includes an acceleration module (54), a scaling module (60), and a final command module (61). The acceleration module (54) determines a hand wheel acceleration (90). The scaling module (60) determines a rejection command (52). The rejection command (52) is based on the hand wheel acceleration (90) and a road wheel frequency. The final command module (61) determines an adjusted assist command (53) that is based on a normal assist command (A) and the rejection command (52).
