摘要:
In one example, a method includes, transitioning, by a vehicle computing system (VCS) and responsive to determining that a vehicle that includes the VCS is idle, into a maintenance mode during which the VCS is not likely to be accessed by an occupant of the vehicle; while operating in the maintenance mode, performing, by the VCS, one or more maintenance tasks; in response to determining that no maintenance tasks are scheduled or that performance of the one or more maintenance tasks are complete, transitioning, by the VCS, into a low-power mode, wherein the VCS consumes a greater amount of power when operating in the maintenance mode than when operating in the low-power mode; and periodically transitioning, by the VCS and from the low-power mode, into the maintenance mode to determine whether any new maintenance tasks are available.

A method and apparatus for providing an advised driving speed to a driver of a vehicle travelling on a road network is disclosed. The method comprises determining an advised driving speed of a vehicle for a portion of the road network currently being traversed, determining a current speed of the vehicle on the portion of the road network, and determining a speed limit and/or an expected driving speed for the portion of the road network. An indication of the advised driving speed is then provided to the driver of the vehicle when: (i) the current speed of the vehicle is greater than a first threshold value based on the advised driving speed; and (ii) the speed limit and/or the expected driving speed is greater than a second threshold value. A method and apparatus is also disclosed for determining a score indicative of the compliance of a driver of a vehicle to an advised driving speed during a journey on a road network.

A method and apparatus for providing an indication to a driver of a geared vehicle that the vehicle is not in an optimal gear is disclosed. The method comprises determining a current gear of the vehicle and determining a current speed of a drive unit of the vehicle. An indication is then provided to the driver of the vehicle that the vehicle is not in an optimal gear when: (i) the determined current speed of the drive unit is greater than a predetermined threshold; and (ii) the determined current gear of the vehicle is less than a maximum gear of the vehicle. A method and apparatus is also disclosed for determining a score indicative of the amount of time during a journey on a road network that a geared vehicle is driven in an optimal gear.

System zur Beurteilung und/oder Optimierung des Betriebsverhaltens eines Fahrzeugs, welches wenigstens eine Vorrichtung zur Brennstoffverarbeitung, insbesondere eine Brennkraftmaschine und/oder eine Brennstoffzelle, aufweist, wobei das System aufweist: eine Mehrzahl erster Sensoren, eingerichtet zum Messen von Parametern, welche geeignet sind, einen Fahrzeugbetriebszustand des Fahrzeugs zu charakterisieren; wenigstens einen zweiten Sensor eingerichtet zum Messen wenigstens eines Parameters, welcher geeignet ist, eine Emission der Vorrichtung zur Brennstoffverarbeitung zu charakterisieren; eine Steuereinrichtung, eingerichtet zum wiederholten Messen über eine vorgegebene Zeitdauer und zum Bestimmen eines Fahrzeugbetriebszustands auf der Grundlage eines ersten Datensatzes mit Messwerten der Mehrzahl erster Sensoren und von vordefinierten Parameterbereichen, welche wenigstens einen vordefinierten Fahrzeugbetriebszustand beschreiben; eine Zuordnungseinrichtung, eingerichtet zum Zuordnen eines zweiten Datensatzes mit Messwerten des wenigstens einen zweiten Sensors zu dem wenigstens einen vordefinierten Fahrzeugbetriebszustand; und eine Auswerteeinrichtung, eingerichtet zum Ermitteln wenigstens eines Kennwerts zur Beurteilung und/oder Optimierung des Betriebsverhaltens des Fahrzeugs auf der Grundlage des wenigstens einen Fahrzeugbetriebszustands und des zweiten Datensatzes, wobei der Kennwert geeignet ist, eine Energieeffizienz des Fahrzeugs und/oder ein Emissionsverhalten der Vorrichtung zur Brennstoffverarbeitung zu charakterisieren.
摘要:
Vehicles in transit within a location may transmit and/or receive information about transit events arising within the location, such as accidents, developing weather, and road obstructions. Because localized exchange channels, such as a radiofrequency broadcast, may be range-limited and/or unreliable, a centralized service may be provided to facilitate the exchange of notifications about transit events, but it may be difficult to provide a centralized service that is both scalable to millions of vehicles and capable of low-latency exchange of time-sensitive notifications for transit events. The techniques presented herein provide an architecture for broadcasting transit events through a transit service that maintains vehicle area groups, respectively identifying the vehicles that are associated with each location. The service may receive a notification of a transit event for a location, and may utilize the vehicle area group for the location to broadcast the notification to the other vehicles of the area group.
摘要:
Among other things, one or more techniques and/or systems are provided for providing users with access to a route for travelling. A user, of a client device, may send a request for access to the route to a route planning service. The route may correspond to a starting location and an ending location. The route planning service may query a route database to identify an entry indicating that a restricted access road segment (e.g., a high occupancy vehicle lane, a shoulder lane, a bus lane, etc.) and/or a road segment (e.g., comprising a traffic light alteration capability) exists between the starting location and the ending location. Responsive to successfully authorizing the user for travelling the restricted access road segment and/or the road segment, the route, comprising the restricted access road segment and/or the road segment, may be provided to the client device.
