Title: Shuhan Liu and Reconfigurable Steer-by-Wire Steering Feel

Introduction

Shuhan Liu is an inventor based in Shanghai, China, whose work includes a patent for a reconfigurable steering feel design method and control system for steer-by-wire. The invention addresses how a steer-by-wire system can provide adjustable steering feedback to suit different hardware characteristics and steering feel requirements.

Latest Patents

Liu’s listed patent, “Reconfigurable Steering Feel Design Method and Control System for Steer-by-Wire,” describes a feedback model that combines alignment torque based on observed rack force, assist torque, friction compensation, damping compensation, inertia compensation, and soft-stop limiting torque. The system adds the outputs of these modules to calculate the expected steering feel motor torque. It uses steering wheel angle, speed, and torque, along with observed rack force and vehicle speed, as inputs, then sends the calculated torque to a steering feel motor to provide feedback through the steering wheel. Adjustable parameters in each module allow the steering feel to be reconfigured.

Career Highlights

Liu is associated with Shanghai Jiao Tong University. His listed patent count is 1 patent, reflecting an invention focused on configurable steering feedback for steer-by-wire technology.
