Abstract: Disclosed herein are a method and apparatus for automated following behind a lead vehicle. The lead vehicle navigates a path from a starting point to a destination. The lead vehicle and the following vehicle are connected via V2V communication, allowing one or more following vehicles to detect the path taken by the lead vehicle. A computerized control system on the following vehicle (a Follow-the-Leader, or FTL, system) allows the following vehicle to mimic the behavior of the lead vehicle, with the FTL system controlling steering to guide the following vehicle along the path previously navigated by the lead vehicle. In some embodiments, the lead vehicle and following vehicle may both use Global Navigation Satellite System (GNSS) position coordinates. In some embodiments, the following vehicle may also have a system of sensors to maintain a gap between the following and lead vehicles.

Abstract: Systems and methods for increasing the efficiency of vehicle platooning systems are described. In one aspect, data associated with two or more vehicles is received by a system. The data received by the system may be used by a system to track and analyze fleet locations, activities, and fuel efficiency among other attributes. In some examples, fleets management systems may provide users with granular information regarding hundreds of vehicles and information about their platooning systems. Systems and methods described herein also indicated how fleet management and analysis systems can be used to create safer and more fuel-efficient trips.

Abstract: Methods and systems for generating, deriving, and enhancing drivable road databases are provided. A baseline road in a road network is defined and position and/or trajectory data collected by vehicles traveling the baseline road are compiled and compared to a representation of the baseline road in an existing database. Identity and/or other property information about the road are assigned form the existing database to the new database.

Abstract: A system and method identifies road features that may not appear on a map database, such as paths not described as roads on the map database, and whether all the roads at a crossing cross at the same grade level. The system and method may thus be used to identify points of departure from, or points of merging onto, a road described by the map database or a path identified as described herein, but not described by the map database.

Abstract: A user interface for use in a vehicle navigation and traffic information device. Various adaptable menu commands and intuitive UI elements are provided to ease user navigation of the interface and to minimize driver distraction while providing information in an optimized manner.

Abstract: A method and system for storing and retrieving spatial data objects from a spatial database is discussed. The system stores multi-dimensional objects within the database by determining their position in a multi-tiered coordinate system. One each object has been assigned to a particular coordinate, the object is further assigned to one of many overlapping sections within the coordinate system. Each object is assigned to a particular section of the coordinate system depending on its overall size and position.

Abstract: Specified streets or intersections that are within a specified distance of a specified city can be found by a search, even when they are not actually in that city. For computational efficiency, some addresses are included in search results even when they exceed the specified distance from the specified city by a small amount (“false positives”). The search method guarantees that no instance of the street name within the specified distance of the specified city is erroneously missed (“false negatives”).
