Vehicle periphery information management device
Provided is a vehicle periphery information management device that can reduce the load on a network and the processing load on the acquisition side. The vehicle periphery information management device includes: a data acquisition unit that acquires a plurality of pieces of external environment information data in the periphery of the vehicle; and a data selection unit that selects a portion of the plurality of pieces of external environment information data acquired by the data acquisition unit and outputs the selected data to an external unit on the basis of a prescribed position from the vehicle.
1. A vehicle periphery information management device comprising:
a data acquisition unit configured to acquire a plurality of pieces of external environment information data around a vehicle; and
a data selection unit configured to select a part of the plurality of pieces of external environment information data and output the selected data to the outside, wherein the data selection unit is configured to
recognize from the external environment information data a travelable region in which the vehicle travels, and
delete information on a region other than the travelable region, wherein
the external environment information data includes first information on a predetermined region ahead of the vehicle, and second information on a region outside the predetermined region,
the part of the information to be deleted is determined on the basis of low priority information having lower priority as information from a safety aspect than a predetermined value,
the low priority information is information on an object that cannot collide with the vehicle,
the low priority information is obtained by removing from the external environment information data information on an object that can enter the travelable region, and
the deleting includes setting some transmission cycles to be longer than a default value on the basis of the low priority information.
2. The vehicle periphery information management device according to claim 1 , wherein deleting includes decimating a part of the information to be transmitted on the basis of the low priority information.
3. The vehicle periphery information management device according to claim 1 , wherein deleting includes compressing a part of the information to be transmitted on the basis of the low priority information.
4. The vehicle periphery information management device according to claim 3 , further comprising:
a coordinate conversion processing unit configured to integrate coordinate systems of the plurality of pieces of external environment information data, wherein
the data selection unit is configured to recognize the travelable region from the external environment information data with the integrated coordinate systems.
5. The vehicle periphery information management device according to claim 4 , further comprising:
a synchronization processing unit configured to synchronize the acquisition times of the plurality of pieces of external environment information data, wherein
the data selection unit is configured to recognize the travelable region from the synchronized external environment information data.
6. The vehicle periphery information management device according to claim 5 , further comprising:
a grouping processing unit configured to perform, for identical objects among the plurality of pieces of external environment information data, grouping of the objects, wherein
the data selection unit is configured to recognize the travelable region from the external environment information data for which the grouping has been performed.
7. The vehicle periphery information management device according to claim 6 , further comprising:
a tracking processing unit configured to perform, for identical objects among the plurality of pieces of external environment information data, tracking processing on the objects, wherein
the data selection unit is configured to recognize the travelable region from the external environment information data for which the tracking processing has been performed.
