Abstract
A system includes a processor configured to receive vehicle speed and heading. The processor is also configured to determine a local data set having coordinates reachable by a vehicle traveling at a projected speed based on the received speed and heading within a predetermined amount of time. The processor is further configured to define a geo-fence at a distance from a local data set perimeter such that a vehicle reaching the geo-fence at the received speed will have time to download new local data before reaching the local data set perimeter and send the geo-fence definition and coordinate data within the local data set to the vehicle.
Claims20
A system comprising:
- a processor configured to:
- receive vehicle speed and heading;
- define a first local data set of map data around a vehicle location bounded by a perimeter projected to be reachable by a vehicle traveling within the perimeter within a predetermined amount of time, based on the received speed and heading;
- define a geo-fence within and at a distance from the perimeter such that a vehicle reaching the geo-fence at the received speed will have time to download a second local data set before reaching the first local data set perimeter;
- and
- send the geo-fence definition and first data set to the vehicle.
A system comprising:
- a processor configured to:
- responsive to a local data request, define a local data boundary and a geo-fence within the boundary for triggering an additional-data request based on a vehicle speed and data download speed, the local data boundary defined by coordinates projected to be reachable by a vehicle within a predetermined time period;
- and
- transmit the geo-fence and map data within the local data boundary to a vehicle.
A system comprising:
- a processor configured to:
- receive local map data, a geo-fence around a present vehicle location and contained within an outer boundary of the map data, and maximum expected travel speed;
- track vehicle progress until the geo-fence is encountered;
- request new local map data upon encountering the geo-fence;
- and
- redefine the geo-fence to be closer to a vehicle location than the received geo-fence responsive to vehicle speed exceeding the maximum expected travel speed.
