摘要:
Embodiments provide systems and methods that find the quickest route between two locations on a graph with multi-edge constraints in a time and space efficient manner. In some embodiments, Dijkstra's algorithm is split into separate universes when a) a multiple-edge constraint is reached, and b) along each edge of a multi-edge constraint. In some embodiments, the split is performed for the purpose of finding the quickest (i.e. lowest weighted) route to the intersect ion(s) at the end of the constraints. These universes, in some embodiments, are merged or discarded when the intersection at the end of the constraint is found. Using these systems and methods, in some embodiments, the shortest path between two locations of a multi-edge constrained road network can be efficiently determined.

A vehicle management system can generate a vehicle management user interface that depicts vehicle history information in timelines or graphical timelines. These history timelines can include information regarding vehicle location, speed, and idling, among other useful information. The graphical nature of the history timelines can quickly convey vehicle tracking details and potential problems, such as idling and congregation, to an administrator. Further, history timelines for multiple vehicles can be displayed in parallel, allowing comparison between histories for different vehicles.
摘要:
Vehicle management systems and associated processes can consider energy consumption when selecting routes for fleet vehicles. Vehicle management systems and associated processes are described that, in certain embodiments, evaluate vehicle energy usage based on factors such as terrain or elevation, vehicle characteristics, driver characteristics, road conditions, traffic, speed limits, stop time, turn information, traffic information, and weather information, and the like. The features described herein may also be implemented for non-fleet vehicles, such as in personal vehicle navigation systems.

摘要:
An AC power system for recreational vehicle includes an input circuit for receiving alternating current and at least one output circuit providing alternating current to devices. A park brake circuit is provided for producing a vehicle brake signal, deactivation signal, and an ignition circuit provides a vehicle engine ignition signal. An interlock provides for disabling the output circuit in response to at least one of the brake signal and ignition signals.
