Abstract
Official abstract text for this publication.
A method of controlling an electric power steering system of a vehicle is provided. The method estimates steering rack force to be caused by a tire of the vehicle and a surface of a ground with which the tire is in contact in response to determining that one or more hand wheel torque sensors of the vehicle are not enabled. The method generates a steering assist torque command based on the estimated steering rack force. The method controls the electric power steering system using the steering assist torque command.
First claim
Opening claim text (preview).
Having thus described the invention, it is claimed: 1. A method of controlling an electric power steering system of a vehicle, the method comprising: filtering a hand wheel angle with a low-pass filter; filtering a hand wheel velocity with a low-pass filter; determining that one or more hand wheel torque sensors of the vehicle are not enabled; estimating steering rack force caused by a tire of the vehicle and a surface of a ground with which the tire is in contact with the f…
