External Human-machine Interface Design for Automated Vehicles Based on Analytic Hierarchy Process

Abstract: This research provides a theoretical basis and guidance for the design by establishing a demand index system for the external human-machine interface for automated vehicles. First of all, starting from literature research, combined with market product analysis and user interviews, to establish functional demand indicators for the design of external human-machine interface, then collect data through user surveys, and calculate through AHP to obtain the weights of each level and each element. Clarify the preference characteristics of each demand and carry out consistency test to establish an evaluation system to provide a basis for subsequent decision-making and design practice. Finally, combining the research conclusions and design practice, an external human-machine interface for automated vehicles is designed that meets the user's preferences and characteristics, and provides a usable and effective interface for pedestrians.
