Map selection device, storage medium storing computer program for map selection and map selection method
A map selection device having an acquisition device that acquires a traveling route from the current location of a vehicle to a destination, a storage device that stores multiple maps, and a processor configured to select one or more maps containing a traveling route from among the multiple maps stored in the memory, so as to include the region from the current location on the traveling route to the destination, and, when multiple map candidates exist containing a single zone included in the traveling route, to select a map candidate suitable for automatic control as the map to be utilized for traveling in the zone.
1. A map selection device comprising:
an acquisition device that acquires a traveling route from the current location of a self-driving vehicle to a destination;
a storage device that stores multiple maps; and
a processor configured to
select a plurality of map candidates for a first zone included in the traveling route from among the multiple maps stored in the storage device,
calculate an evaluation value for each of the map candidates based on a maximum control level for automatic control at which travel is possible for hardware of the self-driving vehicle using the map candidate, and
select, from among the map candidates, a first map candidate having the highest evaluation value for the first zone, wherein
the evaluation value is calculated based on (i) the hardware of the self-driving vehicle and (ii) the length of period between the current time and the time at which each map candidate was created.
2. The map selection device according to claim 1 , wherein the processor is further configured to determine the length of the first zone of the traveling route contained in each of the map candidates, for each control level for automatic control corresponding to the selected map candidates, and to calculate a distance that the self-driving vehicle can travel with each of multiple control levels when the self-driving vehicle is traveling on the traveling route.
3. A computer-readable non-transitory storage medium that stores a computer program for map selection, which causes a processor:
to input a traveling route from the current location of a self-driving vehicle to a destination via an acquisition device;
to select a plurality of map candidates for a first zone included in the traveling route from among multiple maps stored in a storage device;
to calculate an evaluation value for each of the map candidates based on a maximum control level for automatic control at which travel is possible for hardware of the self-driving vehicle using the map candidate; and
to select, from among the map candidates, a first map candidate having the highest evaluation value for the first zone, wherein
the evaluation value is calculated based on (i) the hardware of the self-driving vehicle and (ii) the length of period between the current time and the time at which each map candidate was created.
