摘要： 越障性能是越野车辆通过性能的核心评价指标之一，《汽车地形通过性试验方法》 （GB/T 12541－2023）已明确规定车辆通过性的试验项目、条件及设施特征表，并对各类车 型的试验条目提出要求与推荐。文章以 4×4 车型为研究对象，在排除车辆因底部触障、附着 力不足等失效场景的前提下，聚焦地形通过性中的垂直越障高度与水平壕沟宽度两项参数， 推导得出其理论计算公式。结合车辆实际工况开展试验，验证了该理论公式的可行性，同时 基于试验结果，对垂直越障高度与水平越壕宽度的参数目标设定进行简要分析，为后续车型 设计提供了思路与方法。

Abstract: Obstacle crossing performance is one of the important evaluation indicators for off-road vehicle passability. Test Methods For Vehicle Passeability (GB/T 12541–2023) specifies the test items, conditions, and facility characteristics related to vehicle passability, and provides requirements and recommendations for test items for various vehicle types. This article takes the 4×4 vehicle model as the object, and studies the two parameters of vertical obstacle crossing height and horizontal trench in terrain passability, except for the failure caused by the vehicle not encountering obstacles at the bottom and insufficient adhesion. Theoretical calculation formulas are obtained, and the feasibility of the theoretical calculation formulas is experimentally verified by combining the actual situation of the vehicle. At the same time, based on experimental verification, a simple analysis is conducted on the setting of parameters for vertical obstacle height and horizontal trench width, providing ideas and methods for the design of subsequent vehicle models.

Key words: vertical obstacle crossing height; horizontal trench width; calculation verification; test verification
