Research on Evaluation Index System of Automobile HMI User Experience.

Under the background of intelligence, networking and experience economy, the user experience of automotive HMI products, as a key point of differentiation of the whole vehicle, affects the purchase decision of consumers. In order to manage and optimize the user experience of automotive HMI products, it is necessary to build a scientific and reasonable evaluation system. This study summarizes the evaluation indexes used in the relevant literature in the past ten years through the content analysis method, and forms a general index library for the evaluation of automotive HMI user experience; and based on this, the evaluation index system of Wuling automotive HMI user experience is constructed by combining user interviews, real-vehicle review and AHP method. The evaluation index system consists of 3 first-level indexes, 6 s-level indexes and 30 three-level indexes; among the first-level indexes, driving compatibility, user satisfaction and HMI efficacy is each given a weight of 0.383, 0.338, and 0.269 respectively. The out-put evaluation index system can provide reference for evaluating the user experience of automotive HMI, which is conducive to the design evaluation and optimization iteration of automotive HMI products; the universal user experience evaluation index library comprehensively summarizes the index types, which can help researchers find the indexes matching their own needs quickly; In addition, the method and process of the evaluation system construction can be a reference and guidance for other manufacturers to build the index system that meets their own needs.
