As automobiles are gradually transforming from independent mechanical units to network nodes with intelligent and networked functions, the functions and performance evaluation of intelligent vehicles is facing the new challenges. At present, China has initially classified the level of intelligent vehicles on the basis of SAE, but has not yet formed a scientific, rigorous and comprehensive evaluation system. Therefore, this paper proposes the detailed intelligent evaluation ideas of intelligent vehicles in different levels from 0 to 5 and sets up a "Trinity" evaluation system covering professional evaluation, practical evaluation and market evaluation. Then, with the development progress of intelligent vehicles, we will set up the hierarchical structure of evaluation indicators basing on automated intelligence and connected intelligence. After that, we will comprehensively utilize the advantages and disadvantages of the subjective and objective evaluation methods to determine the weight of the index, and give the concrete implementation flow of the intelligent vehicle evaluation example according to the evaluation model. The final calculation of the scores and the star rating results may provide a basis for judging the level of intelligent vehicles, which will not only promote intelligent vehicles in the overall safety, experience, energy consumption, efficiency, etc., but also provide a comprehensive and reliable reference value for businesses and consumers.
