Road wheel disturbance rejection

摘要

A control method for an electric power steering system is provided. The control method includes evaluating wheel disturbance based on a wheel velocity. A wheel disturbance cancel amount is determined based on the wheel velocity. An assist command is generated to the power steering system based on the wheel disturbance cancel amount.

1. A control system for a power steering system, comprising:
a first module that evaluates a wheel disturbance based on a wheel velocity and that determines a wheel disturbance cancel amount based on a handwheel torque and a filtered wheel velocity generated by applying a filter to the wheel velocity, the filter based on a frequency of a variation of a wheel sensor signal indicating the wheel velocity; and a second module that generates a final assist command to the power steering system based on the wheel disturbance cancel amount and the filtered wheel velocity.
