Abstract: The automated driving assistance function technology cannot undergo development without objective test evaluation methods. However, subjective evaluation by independent experts is required in the evaluation, which leads to subjectivity in the direct results. This study uses the i-VISTA test specification to obtain objective and reasonable results. It combines natural Chinese driving data to develop test scenarios that meet national traffic conditions. Taking the adaptive cruise control system function as an example, we propose a gray comprehensive evaluation method based on a subjective-objective wide weighting of the adaptive cruise control (ACC) system. First, we use the analytic hierarchy process (AHP) method and entropy method to obtain the comprehensive subjective-objective wide weight coefficients of evaluation indices, respectively. Then, we apply the comprehensive weight to the grey method, which provides superior subjective and objective evaluation consistency. Compared with the traditional method, it overcomes the arbitrariness of the subjective assignment method and is more objective and reasonable.
