Abstract
Official abstract text for this publication.
A method of controlling an electric power steering system is provided. The method includes: determining a scale factor based on a handwheel position; applying the scale factor to a hand wheel torque value to scale the hand wheel torque value; and generating a corrected handwheel torque signal based on the scaled hand wheel torque value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system for an electric power steering system, comprising: a scale factor determination module that determines a scale factor based on a handwheel position adjusted by a torque correction phase that is determined based on analysis of a cardan joint of the power steering system; and a harmonic pinion torque correction module that applies the scale factor to a hand wheel torque value to scale the hand wheel torque value, and that generates a c…
