Abstract: With the development of intelligent and networked vehicle technologies, the automotive human-machine interface (HMI) has become important to the drivers’ user experience as a medium between human and vehicle. In order to improve the teamwork between human and vehicle by optimizing the human-machine interface, the evaluation and design method of automotive human-machine interface was studied. Twenty-six drivers participated in the evaluation of driving simulator with FM as the multi-path interface paradigm. The evaluation method was based on the team situation awareness theory and user experience elements. A multi-dimensional evaluation system containing driving indicators, behavioral indicators, and subjective indicators was constructed. The association between situation awareness and user experience elements was further examined by analyzing task stages and channels before the experiment, and the results of the five levels of user experience data of the automotive HMI were analyzed after the experiment, thus locating the occurrence of design problems and deducing the corresponding design optimization directions. Finally, the design optimization solution was obtained, which can help optimize the design of automotive HMIs and enhance user experience.
