The interaction environment of traditional vehicle cockpit has a single mode, a single media channel, and a single scenario of human-vehicle interaction. With the development of the scenarios of the metaverse intelligent cockpit of the autonomous vehicle toward intelligent interaction, multi-mode, multi-media, and diversified modes of human-vehicle interaction and scenario interaction, it is urgent to optimize the scenario interaction design method of the intelligent cockpit through the theory of spatial scenario interaction. The intelligent cockpit scenario interaction model was constructed with the help of scenario theory and case analysis, the interaction design features of XR HMI vehicle system were analyzed, the multimodal human-vehicle interaction scenarios were summarized, and the scenario interaction design strategy for the metaverse intelligent cockpit of autonomous vehicle was proposed. The intelligent cockpit AR scenario, VR scenario, XR scenario and virtual hybrid scenario were built, and SMIM intelligent cockpit scenario interaction model and interaction design strategy were launched. Material flow, information flow, energy flow, capital flow, and experience mind flow together constitute the elements of the scenario interaction model of intelligent cockpit, which has important guiding significance and application value for human-vehicle interaction, intelligent space interaction, and intelligent interaction of metaverse content of autonomous vehicle metaverse.
