Safety of intended functionality of intelligent vehicles was directly affected by their sensing ability of driving scenarios. In order to evaluate scenarios accurately and reliably from a perceptual level, a new evaluation method was proposed. By using fuzzy reasoning and based on analysis of scenarios and elements, fuzzy judgment of scenarios was made from a perspective of drivers' perception, and their fuzzy level was established before correlation between scenario factors was developed by utilizing fuzzy relationship. Then, evaluation value was calculated according to decision function. In the end, rationality of the evaluation method was verified. The results show that this method could achieve a comprehensive understanding of scenarios by integrating driver's perception of them, thus proving to be feasible in scenario evaluation.

Key words: intelligent vehicle, safety of intended functionality, scenario evaluation, fuzzy reasoning, autonomous driving
