Study on Human-Machine Shared Driving System Using DYC and Steering Assistance

- Effectiveness of Assistance on Elderly Drivers in Course Tracking Maneuver -

Abstract

This paper investigates a new shared driving system which combines Direct Yaw-Moment Control (DYC) and steering assistance system. Conventional steering assistance systems had a drawback in causing interference between the steering torque from the driver and the steering assistance systems. The proposed system can potentially solve the interference problem while achieving satisfactory course–tracking performance, as DYC is used as an independent control input. The reduction of steering assistance torque can potentially reduce the degree of the interference between the driver and the steering assist torque. Driving simulator experiment is conducted to verify the effectiveness of the proposed shared driving system by using elderly drivers.
