Abstract: The actual vehicle road test with the user scenario as the core is an important part of the availability evaluation of the in-vehicle infotainment system, and the evaluation of this part is more subjective and therefore more difficult than the traditional in-vehicle infotainment system functional performance test. The core of the usability evaluation contains two parts: the evaluation scene and the evaluation dimension. The sufficient valuation scene can restore the actual usage completely and make the evaluation more directly and comprehensively. Evaluation dimension is the key point of assignment, which mentoring the evaluator in the progress of evaluation, so as to guide evaluators to perceive the advantages and disadvantages of the system. By combining the evaluation scenarios and evaluation dimensions, and applied it to the evaluation work of the actual vehicle in-vehicle infotainment system. It can effectively improve the perception and evaluation ability of evaluators, so as to make up for the defects of the expert evaluation method with high requirements for evaluation experience, and effectively improve the efficiency of testing and evaluation. Optimize the human-computer interaction design of the in-vehicle infotainment system from the perspective of vehicle verification. It will play a positive role in promoting the competitiveness of products in the in-vehicle infotainment system.
