Evaluation Method for Driver’s Perceived Value of Steering Reaction Force

Abstract

The purpose of this study is to develop an evaluation method for driver’s perceived value of steering reaction force during steering in one direction. It is clarified that magnitude of the perceived reaction force can be numerically converted from steering wheel torque and a gradient of the steering wheel torque to the angle. Authors develop a method for estimating a changing trend of the magnitude of the perceived reaction force from a relationship between the steering wheel torque and angle. This method can quantitatively predict the actual feeling of the reaction force.
