The functional requirements and weights of vehicle owners in the mobile terminal and car interaction can be effectively obtained. The key design elements based on requirements can be therefore determined and quantified to effectively improve user satisfaction in the mobile terminal interface and vehicle interaction process, and enhance the user experience. First of all, the user journey map of the behavior path of the vehicle owner was established when interacting with the vehicle on the mobile terminal and summarizing the user needs. Then, based on the Kano model, the priority of requirements was qualitatively analyzed from two dimensions of user satisfaction and functional perfection. According to the priority of requirement, the importance of design needs was measured and quantified by the QFD model. When the user interacts with the vehicle on the mobile terminal device, the weight of the demand for battery related information feedback, the demand for vehicle surrounding environment feedback, and the demand for tire pressure monitoring is the largest, which is an important design demand in the mobile terminal interaction design process of NEVs. Based on the way of building Kano model and building the "House of Quality (QFD)" according to the user travel graph, the mobile terminal interaction of NEVs is designed and studied, which can verify the possibility of its method in solving similar design problems, and provide methodological guidance for the interaction design of a large number of NEVs and users on the mobile terminal in the future.
