Abstract

Provided is an information processing apparatus including: a processor; a storage device that is connected to the processor; a display apparatus that is connected to the processor; and a communication apparatus that is connected to the processor and communicates with a server apparatus, wherein the storage device holds map information indicating a connection relationship between roads, when the processor receives information indicating a completion degree of automatic driving track information including coordinate values of a traveling track when a vehicle travels on each road by automatic driving from the server apparatus through the communication apparatus, the processor holds the information indicating the completion degree in the storage device, and the display apparatus displays a map including the roads based on the map information, and superimposes and displays information indicating the completion degree calculated for each of the roads on the map.

First claim

What is claimed is:

1. An information processing apparatus comprising: a processor; a storage device that is connected to the processor; a display apparatus that is connected to the processor; and a communication apparatus that is connected to the processor and communicates with a server apparatus,
wherein the storage device holds map information indicating a connection relationship between roads,
when the processor receives information indicating a completion degree of automatic driving track information including coordinate values of a traveling track when a vehicle travels on each road by automatic driving from the server apparatus through the communication apparatus, the processor holds the information indicating the completion degree in the storage device,
update a traveling track number to a first predetermined amount, a coordinate number to a second predetermined amount, and a coordinate of the coordinate number to a third predetermined amount,
determine if a value is stored corresponding to the updated traveling track number and the updated coordinate number,
when the value stored corresponds, determine if the updated traveling track number is less than or equal to a predetermined amount,
when the updated traveling track number is less than or equal to the predetermined amount, update the coordinate of the coordinate number to include a coordinate of the coordinate number among coordinate point groups of the traveling track number, and update the traveling track number by one,
when the updated traveling track number is greater than the predetermined amount,
update the coordinate of the coordinate number to the coordinate number divided by the predetermined amount,
update the traveling track number to the first predetermined amount, and update the coordinate number by one,
update the coordinate of the coordinate number to the third predetermined amount,

when the value stored does not correspond, store the coordinate of the coordinate number as a driving track, and
the display apparatus displays a map including the roads based on the map information and the driving track, and superimposes and displays information indicating the completion degree calculated for each of the roads on the map.

2. The information processing apparatus according to claim 1 , wherein
the information processing apparatus is mounted in the vehicle,
the processor transmits traveling track information including coordinate values of a track of the vehicle traveling on a road by manual driving to the server apparatus through the communication apparatus,
the completion degree is a ratio of an amount of the traveling track information that has been already received by the server apparatus to an amount of the traveling track information determined to be required for calculating the coordinate values of the track of the road used for the automatic driving of the vehicle, the ratio being calculated for each of the roads,
the information indicating the completion degree is an incentive value that is calculated based on the completion degree and is an incentive for allowing the vehicle to travel on the road by the manual driving, and
the incentive value is calculated so that the incentive value of the road of which the completion degree is 1 indicating that the automatic driving track information is completed is the lowest and the incentive value of the road of which the completion degree is less than 1 becomes larger as the completion degree becomes larger.

3. An automatic driving track management system comprising:
an information processing apparatus that is mounted in a vehicle; and
a server apparatus that communicates with the information processing apparatus, wherein
the information processing apparatus transmits traveling track information including coordinate values of a track of the vehicle traveling on a road by manual driving to the server apparatus, and a plurality of coordinate numbers including the coordinate number, and each of the plurality of coordinate numbers corresponds to one of the coordinate values,
the server apparatus calculates a completion degree of automatic driving track information including coordinate values of a track on which the vehicle travels by automatic driving, for each road, based on the traveling track information received from the information processing apparatus, and transmits information indicating the calculated completion degree to the information processing apparatus, and
a display apparatus displays a map including the roads based on map information and the automatic driving track information, and superimposes and displays information indicating the completion degree calculated for each of the roads on the map.

4. The automatic driving track management system according to claim 3 , wherein
the server apparatus calculates a ratio of an amount of the traveling track information that has been already received to an amount of the traveling track information determined to be required for calculating the coordinate values of the track of the road used for the automatic driving of the vehicle as the completion degree of the automatic driving track information, for each of the roads.

5. The automatic driving track management system according to claim 4 , wherein
the server apparatus counts the number of times of collection of the traveling track information and calculates a ratio of the counted number of times of collection to a predetermined number of times of collection as the completion degree of the automatic driving track information, for each of the roads.

6. The automatic driving track management system according to claim 4 , wherein
the server apparatus calculates an incentive value that is an incentive for allowing the vehicle to travel on the road by the manual driving as information indicating the completion degree on the basis of the calculated completion degree for each of the roads, and transmits the incentive value to the information processing apparatus, and
the information processing apparatus outputs the incentive value for each of the roads.

7. The automatic driving track management system according to claim 6 , wherein
the server apparatus calculates the incentive value so that the incentive value of the road of which the completion degree is a value indicating completion of the automatic driving track information is the lowest and the incentive value of the road of which the completion degree is not the value indicating the completion of the automatic driving track information becomes larger as the completion degree becomes larger.

8. The automatic driving track management system according to claim 3 , further comprising:
a positioning apparatus that measures a position of the vehicle,
wherein the traveling track information includes a plurality of coordinate values measured by the positioning apparatus when the vehicle travels on the road by the manual driving.

9. The automatic driving track management system according to claim 8 , further comprising:
a speed sensor that measures a speed of the vehicle,
wherein the traveling track information includes a speed measured by the speed sensor at a point in time in which each of the coordinate values is measured.

10. The automatic driving track management system according to claim 3 , further comprising:
a sensor that measures a traveling situation of the vehicle,
wherein the information processing apparatus transmits information indicating the traveling situation of the vehicle measured by the sensor when the coordinate value of the track of the vehicle is measured to the server apparatus, and
the server apparatus holds first reference information for determining a reliability of the traveling track
