标准摘要
[中文适用范围]： 本部分规定了使用基于卫星定位系统的自动导引装置（AGS）的农用车辆在自动转向模式下评估和报告性能的过程。主要性能指标是车辆上一个代表点相对于预定轨迹的横向偏差。此性能指标整合了车辆引导系统所有组件的不确定性，包括定位设备、自动转向组件以及车辆机构和动态性能。本部分专注于在水平地面上沿直线行驶时自动导引系统的稳态跟踪性能。 [外文原描述]： ISO 12188-2:2012 specifies the process for evaluating and reporting the performance of agricultural vehicles equipped with automated guidance systems based on a global navigation satellite system (GNSS) when operating in an automatic steering mode. The main performance criterion is the lateral deviation of a representative point on the vehicle from a desired trajectory for that point. This performance criterion integrates the uncertainties associated with the performance of all components of the vehicle guidance system including the positioning device(s), automated steering components, and vehicle mechanisms and dynamics. ISO 12188-2:2012 focuses on steady-state tracking performance of the automated guidance system while travelling on straight paths over a level surface.
