Current soil and surface data are not detailed enough to obtain accurate analyses of cross-country movement. The reason for the research presented in this article was the absence of a methodology for the synthetic assessment of the influence of the terrain surface on the movement of military vehicles. The study is based on analyses of data and information sources of soils and surface conditions primarily with the aim to determine their reliability, availability and precision when used for analyses of terrain traversability by off-road vehicles. The key method to achieve the set objective is the employment of tractive charts of military vehicles and utilized coefficients, the coefficient of rolling resistance and the coefficient of adhesion. Input data and information is tested with a comparative method of cross-country movement analyses. Conversion of soil and surface types to tractive chart coefficients is currently not optimal. For the most part, evaluation of soil type is very inaccurate with a wide range of possible values. Results of the analysis propose developing a methodology of evaluating surface and soils for vehicle traversability.

地形表面数据精度对越野车辆导航的影响

当前的土壤和地表数据不够详尽，无法获得越野运动的准确分析。本文提出该研究的原因是，缺乏一种综合评估地形表面对军车运动影响的方法。该研究基于对土壤和地表条件的数据和信息源的分析，主要目的是确定其在用于越野车辆的地形穿越性分析时的可靠性，可用性和精度。达到既定目标的关键方法是使用军用车辆的牵引图和利用系数，滚动阻力系数和附着系数。输入数据和信息使用越野运动分析的比较方法进行测试。从土壤和地表类型到牵引图系数的转换目前不是最佳的。在大多数情况下，对土壤类型的评估在许多可能的值中都是非常不准确的。分析结果建议开发一种评估车辆可行驶性的表面和土壤的方法。
