    • A vehicle-based positioning system (VBPS) for a vehicle traversing a guideway, the VBPS includes an inertial navigation system (INS) on-board the vehicle, wherein the INS is configured to detect inertial parameters of the vehicle while the vehicle traverses the guideway, the detected inertial parameters including roll, pitch and yaw of the vehicle. The VBPS includes a guideway database, wherein the guideway database is configured to store inertial parameters of the guideway at a plurality of locations along the guideway, the stored inertial parameters include roll, pitch and yaw of the guideway. The VBPS further includes a vital on-board controller (VOBC), the VOBC is configured to determine a position of the vehicle based on a comparison of the detected inertial parameters with the stored inertial parameters. The VOBC is configured to limit comparison of the inertial parameters with the stored inertial parameters based on a latest checkpoint passed by the vehicle.
    • 一种用于车辆穿过导轨的车辆定位系统(VBPS),所述VBPS包括车辆上的惯性导航系统(INS),其中所述INS构造成在车辆横过所述导轨时检测所述车辆的惯性参数 检测到的惯性参数包括车辆的滚动,俯仰和偏航。 所述VBPS包括导轨数据库,其中所述导轨数据库被配置为在所述导轨的多个位置处存储所述导轨的惯性参数,所述存储的惯性参数包括所述导轨的滚动,俯仰和偏航。 VBPS还包括重要的车载控制器(VOBC),VOBC被配置为基于检测到的惯性参数与存储的惯性参数的比较来确定车辆的位置。 VOBC被配置为基于车辆通过的最新检查点来限制惯性参数与存储的惯性参数的比较。
