摘要： An embedded system controller-based vehicle tracking system using vehicle positioning. An embedded system controller controls a traffic intersection using an optical system. The embedded system controller receives a vehicle location and a vehicle schedule. The embedded system controller calculates whether the vehicle is on time and reports the on-time status to the driver interface. The driver may -request that the system report a panic or emergency situation to the dispatch center through an external data communications network. The external data communications network may also send vehicle status, such as vehicle position and vehicle condition. A transit company using the system may provide vehicles equipped with the vehicle tracking system with schedules on a daily basis, using a portable data transfer device. The embedded system controller also communicates to the vehicle data network for the communication of vehicle position. A global positioning system receiver may be used to provide the position of the vehicle to the embedded system controller.
摘要翻译：一种基于车载定位的嵌入式系统控制器车辆跟踪系统。嵌入式系统控制器使用光学系统控制交通路口。嵌入式系统控制器接收车辆位置和车辆时间表。嵌入式系统控制器计算车辆是否准时，并将驾驶员接口的准时状态报告。驾驶员可能会要求系统通过外部数据通信网络向调度中心报告紧急情况。外部数据通信网络还可以发送车辆状态，例如车辆位置和车辆状态。使用该系统的中转公司可以使用便携式数据传送装置，每天为装备有车辆跟踪系统的车辆提供日程表。嵌入式系统控制器还与车辆数据网络通信，用于车辆位置的通信。可以使用全球定位系统接收器来将车辆的位置提供给嵌入式系统控制器。
