With the rapid development of the intelligent network connection industry, the focus of the industry has shifted from the demonstration of “large and complete” to the implementation of “specialized and refined”. Therefore, the highway scene has become the most typical technology development path for independent brand enterprises. With the iteration of assistant driving into autonomous driving products, large-scale scenario testing requirements were produced. In this paper, the functional definition of autonomous driving in highway scenes is comprehensively analyzed, and an automated simulation test evaluation system is proposed based on highway autopilot algorithm, and the evaluation results are obtained through empirical analysis, in order to provide technical reference for enterprises to carry out simulation test and evaluation.
