【Abstract】 [Objective]This study proposes a testing method for anti-collision performance of commercial vehicles against road infrastructure, so as to standardize and effectively assess anti-collision performances. [Method] First, typical accidents involving collisions with road infrastructure were reconstructed. Key parameters of collision scenarios were extracted. Based on these, whole-vehicle test scenarios suitable for closed test sites were designed. To meet the requirement for consistent vehicle control during testing, the vehicle trajectory in anti-collision test was fitted in segments. Two vehicle control methods were proposed, i.e., deflectometry method and transverse arc method, which were verified by using M3-Class commercial vehicles equipped with road infrastructure anti-collision systems. [Result] Both proposed methods can activate the vehicles’ anti-collision function. They are effective in testing anti-collision performance of commercial vehicles against with road infrastructure. [Conclusion] Pearson consistency tests were conducted to analyze the consistency of test data from different trajectories. The proposed transverse arc method demonstrates higher data consistency and better driver operation stability in actual testing. Therefore, the transverse arc method is recommended as the preferred approach in the same test conditions.更多还原
