Claims12
An update unit for a vehicle for updating a digital map, said update unit comprising:
- a map unit with a digital map for displaying a travel route on the map;
- wherein the update unit is configured to request an update of a required portion of the map from a system control center;
- and
- wherein the update unit is also configured to:
- receive the requested update of the required portion of the map when the system control center determines that the required portion of the map should be updated based on a comparison between the requested portion and a stored portion stored at the system control center, the map unit displaying the update of the required portion of the map,
- wherein when the system control center determines that the required portion of the map should not be updated based on the comparison between the requested portion and the stored portion stored at the system control center, the update unit does not receive the requested update, and the map unit displays the required portion of the map,
- wherein the system control center is also configured to initiate retrieval of the update of the required portion of the map without receiving a request from the update unit of the vehicle, wherein the system control center is configured to cyclically check the required portion of the map for changes, and wherein the system control center is also configured to establish a degree for the changes in the required portion of the map.
A method for updating a digital map for a vehicle, said method comprising the following steps:
- requesting, by an update unit, an update of a required portion of the map from a system control center;
- cyclically checking the required portion of the map for changes;
- transmitting the requested update, which relates to the required portion of the map, to the update unit by the system control center;
- and
- receiving, by the update unit, the requested update of the required portion of the map when the system control center determines that the required portion of the map should be updated based on changes between the requested portion and a stored portion stored at the system control center, the map unit displaying the update of the required portion of the map,
- wherein when the system control center determines that the required portion of the map should not be updated based on changes between the requested portion and the stored portion stored at the system control center, the update unit does not receive the requested update, and the map unit displays the required portion of the map,
- wherein the system control center is also configured to initiate retrieval of the update of the required portion of the map without receiving a request from the update unit of the vehicle, wherein the system control center is configured to cyclically check the required portion of the map for changes, and wherein the system control center is also configured to establish a degree for the changes in the required portion of the map.
A computer program product stored on a non-transitory computer readable storage medium which, when executed on a processor, instructs the processor to perform the following steps:
- requesting an update of a required portion of a digital map for a vehicle from a system control center;
- and
- receiving the requested update of the required portion of the map when the system control center determines that the required portion of the map should be updated based on a comparison between the requested portion and a stored portion stored at the system control center, and displaying the update of the required portion of the map,
- wherein when the system control center determines that the required portion of the map should not be updated based on the comparison between the requested portion and the stored portion stored at the system control center, the requested update is not received, and the required portion of the map is displayed,
- wherein the system control center is also configured to initiate retrieval of the update of the required portion of the map without receiving a request from the update unit of the vehicle, wherein the system control center is configured to cyclically check the required portion of the map for changes, and wherein the system control center is also configured to establish a degree for the changes in the required portion of the map.
A non-transitory computer-readable medium which stores a computer program product which, when executed on a processor, instructs the processor to perform the following steps:
- requesting an update of a required portion of a digital map for a vehicle from a system control center;
- and
- receiving the requested update of the required portion of the map when the system control center determines that the required portion of the map should be updated based on a comparison between the requested portion and a stored portion stored at the system control center, and displaying the update of the required portion of the map,
- wherein when the system control center determines that the required portion of the map should not be updated based on the comparison between the requested portion and the stored portion stored at the system control center, the requested update is not received, and required portion of the map is displayed,
- wherein the system control center is also configured to initiate retrieval of the update of the required portion of the map without receiving a request from the update unit of the vehicle, wherein the system control center is configured to cyclically check the required portion of the map for changes, and wherein the system control center is also configured to establish a degree for the changes in the required portion of the map.
