Vehicle periphery information management device
A vehicle periphery information management device includes a data acquisition unit, and a data selection unit. The data acquisition unit is configured to acquire a plurality of pieces of external environment information data around a vehicle. The data selection unit is configured to select apart of the plurality of pieces of external environment information data acquired by the data acquisition unit so as to make an output outside, based on a predetermined position of the vehicle.
1. A processor comprising:
a selection unit configured to select a part of a plurality of types of external environment information around a vehicle, and output the selected information outside, the selection unit being configured to
recognize from the external environment information a travelable region, define a movability region for determining whether the vehicle is able to move
to an adjacent traffic lane of the vehicle, and
when the movability region does not include a part of a different vehicle, recognize a part of a region of information on the adjacent traffic lane as information on the travelable region.
2. The processor according to claim 1 , wherein the selection unit is configured to, when the movability region includes at least a part of a different vehicle, not recognize information on the adjacent traffic lane as information on the travelable region.
3. The processor according to claim 1 , wherein a size in a front-rear direction of the movability region is set as a value obtained by adding a margin to a size in a front-rear direction of the vehicle.
4. The processor according to claim 1 , wherein a size in a lateral direction of the movability region is substantially equal to a width of the adjacent traffic lane.
5. The processor according to claim 1 , wherein:
the selection unit is configured to determine the travelable region by comparing a difference between a first distance and a second distance with a threshold,
the first distance is determined on the basis of a distance between the vehicle and a first object present in a traffic lane in which the vehicle is present, and
the second distance is determined on the basis of a distance between the vehicle and a second object present in the adjacent traffic lane.
6. The processor according to claim 2 , wherein
when the movability region includes at least a part of a different vehicle, information on the adjacent traffic lane is deleted, and
the deleting includes setting a transmission cycle for information on the adjacent traffic lane to be longer than a default value.
7. The processor according to claim 2 , wherein
when the movability region includes at least a part of a different vehicle, information on the adjacent traffic lane is deleted, and
the deleting includes decimating information on the adjacent traffic lane to be transmitted.
8. The processor according to claim 2 , wherein
when the movability region includes at least a part of a different vehicle, information on the adjacent traffic lane is deleted, and
the deleting includes compressing information on the adjacent traffic lane to be transmitted.
