Cooperative Steering Characteristics of Driver and Lane-Keeping Assistance System

Abstract

A Lane-Keeping Assistance System can be expected to use in order to reduce driver workload and assist the driver in controlling vehicle. This paper proposes a design of Lane-Keeping Assistance System that uses steering torque as a control input for cooperative steering between driver and assistance system. The cooperative steering performance is evaluated by computer simulation and experiment using driving simulator under side wind disturbance and lane-keeping on curved road. The weighting function is proposed here to vary amount of assistance level in the evaluation of the system in order to examine the cooperative steering characteristics at different assistance level.
