How to Share Control with ADAS? The Impact and Investigation of Human-System Interaction by Joystick for Driver Intervention

This study considers a situation where the driver interacts with the vehicle’s ADAS (SAE level 1/2) by joystick device. Two conditions, the driver using joystick for performing lateral control and automatic lane change function have been considered in this study. The purpose of this study is 1. to investigate the driver’s behavior for evaluate the availability and driving difficulty of the joystick as a candidate for interaction device.; 2. to investigate the driver’s acceptance using the joystick for performing the function. 25 elderly drivers participated in this experiment. The driving simulator simulated the highway scenario. This study concludes that depending on the joystick function, the joystick may be an interaction device of choice. For example, it is recommended as an intermediate device for sharing control with ADAS such as performing the automatic lane change function. The result supported that low accident occurred when they use the joystick to control the vehicle in the first time. Also, the driver subjective feel that the difficulty is low.
