Research On Human-machine Interaction Strategy Design Of Automated Driving Take-over System Based On User Experience

Highly automated driving(HAD)cars will gradually become popular in the next decade,and the switching of control rights among them is a problem that affects driving safety and user experience.Therefore,the design research of the automatic driving takeover system has become a new research trend.With the popularization and development of autopilot technology,the Augment Reality Full Windshield Display(AR-FWSD)technology based on Augmented Reality and Internet-enabled driving has also become more mature,bringing more benefits to the human-computer interaction strategy design of autopilot takeover systems.Multiple design space and design resources.The emergence of the automated driving function has greatly reduced the security risks and provided the driver with more interactive time and space in this complex information system.In this context,how to design a safe,comfortable and fun driving experience is worth discussing.Based on the exploration of user experience and automotive human-machine interface design theory,this paper proposes a vehicle human-computer interaction interface design model based on user experience.Under the guidance of the design model,the situational features of the autopilot takeover situation and the human factors in context were summarized through user interviews and literature research methods.Based on the results of the situation study and the model guidance,the interactive strategy design of the autopilot takeover system was completed and presented in the form of an interactive interface.For further experimental research,this paper designs the simulated driving section and adopts Unity3 D as a simulation platform.It carries a simulation driving hardware and completes the development of a simulated autopilot system.Under simulated autopilot system environment,the availability of layered tiering strategy and game incentive strategy was verified separately.The experimental results show that the adoption of the layered strategy of taking over the warning has no effect on the takeover performance,but it can improve the user experience;the application of the game incentive strategy improves both the takeover performance and the user experience.This paper concludes with a summary of the research results in the research process,including automotive human-machine interface design methods,autopilot takeover context features and human factors,usability experience of experimental research,automated driving takeover system interaction strategy design guide for other researchers later.The research work provides a reference.
