The method also includes: providing mapped data including information relating to a location-related local speed limit and detecting a road construction site according to the actual speed identification and the mapped data.

Abstract: A method determines a weather area for a motor vehicle, with which a sensor system and a communications interface are associated, which are coupled to one another via signals. The method includes: receiving data including geographical information in the form of a map; and creating a grid by dividing the received data into a plurality of adjacent grid cells. The method also includes: providing a measurement signal of the sensor system, representing a location-related local weather situation in one of the grid cells; and determining a local weather area for the respective grid cell according to the provided measurement signal.

Abstract: A process is provided for operating a route acquisition system, configured for determining route data during movement of the route acquisition system along preset routes, and for storing the latter as electronic routes in the data memory. A preset selection of routes is determined as a function of the stored electronic routes. For each route of the preset selection, a route count and a route point in time, and a first and a second route time indication, are determined. A route evaluation is determined for each route based on the assigned route count, the assigned route point in time, and the first and second route time indication. As a function of a determined size of the occupied storage space of the data memory, the respective route of the preset selection is deleted from the data memory as a function of its assigned route evaluation.

Abstract: A vehicle includes a communication unit for the communication with an event management server, a navigation system for the output of at least one route, and a planning system. The planning system is configured to: a) retrieve a list, for a plurality of devices, particularly traffic light systems and/or signal groups of traffic light systems, the list including one identification respectively of the respective device and at least one position indication respectively of the respective device, b) compare the list with the route, in order to select at least one device from the list, c) for the subscription of events with respect to the selected device, send at least one subscription message to the event management server, the subscription message including the identifications of the selected devices.

Abstract: Traffic signal information is estimated based on positioning system data obtained from a plurality of vehicles. Each data set includes the position and the velocity of a vehicle as functions of time. For an intersection having a traffic signal, an average acceleration of the vehicles when leaving the intersection is estimated, and an average deceleration of the vehicles when approaching the intersection is estimated. For each of a subset of the vehicles, a stop duration at the intersection is estimated based on the average acceleration, the average deceleration, and the positioning system data for the respective vehicle. A duration of a red phase of the traffic signal is estimated based on the stop duration of each of the subset of the vehicles.

Abstract: A method for adjusting a vehicle mirror between a standard mirror angle adjustment to a dynamic mirror angle adjustment. The vehicle receives map data of a surrounding area of a vehicle including a first path of travel and a second path of travel. The vehicle also receives vehicle positioning data indicating a vehicle position along one of the first path of travel or the second path of travel. The vehicle then calculates a dynamic mirror angle adjustment based on the vehicle position and map data of the first path of travel and the second path of travel. The vehicle mirror is adjusted by the dynamic mirror angle adjustment relative to a standard mirror angle adjustment.

Abstract: Geographically-relevant information is provided to mobile users by having an information source provide location-referenced information to one or more backend server systems. In response, the backend server system determines a region for which the received location-referenced information is relevant, and then identifies one or more specific cellular base stations that provide wireless broadcast service over an actual broadcast region which covers at least a majority of the determined region. A condition message may then be provided to each of the identified cellular base stations, which are correspondingly instructed to wirelessly broadcast the message over the actual broadcast region.
