Development of lane change driver model for closed-loop simulation of the active safety system

Abstract

In this paper, the integrated lane change driver model was proposed and used in simulations of closed loop simulation of the ESC system. Through the lane change experimental data, the driver's characteristics can be obtained and analyzed. By using the lane change steering input and the lane following steering input with weighting factors, lateral driver model is operated steering action to change or follow the lane. Also, simulation results of the proposed lane change model are compared with the experimental test data, and closed loop evaluation was conducted with ESC system. It has been shown that the proposed integrated lane change driver model can control a vehicle very similar to human manual driving in lane change situations and can represent a normal driver's driving motion. Consequently, the proposed driver model presented in this study can be used into a closed-loop simulation and development of the vehicle's intelligent safety system.
