Abstract

A center prescribes, to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression. A center-side checking section checks, based on its own check criterion, appropriateness of at least one of the type of the vehicle data, the conditional expression, the sampling cycle, and the checking cycle. A vehicle-side checking section checks whether the resources of the subject vehicle are appropriate when the vehicle data is collected based on the prescription from the center.

Claims

1. A remote vehicle data collection system comprising a center that manages traveling information of a plurality of vehicles, wherein

the center is configured to prescribe, to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression,

the center is configured to read, through wireless communication, the vehicle data collected based on the prescription,

the center includes a check criterion and a center-side checking section,

the center-side checking section is configured to check, based on the check criterion, appropriateness of at least one of the type of the vehicle data, the conditional expression, the sampling cycle, and the checking cycle that is prescribed to the subject vehicle,

the subject vehicle includes a vehicle-side checking section, which is configured to check whether resources of the subject vehicle are appropriate, and

the vehicle-side checking section is configured to check whether the resources of the subject vehicle are appropriate when the vehicle data is collected based on the prescription from the center.

2. The remote vehicle data collection system according to claim 1, wherein

the center has a database as the check criterion,

the database is configured to associate the type of the subject vehicle with a type of vehicle data that is collectable in a vehicle of the type of the subject vehicle,

the center-side checking section is configured to identify, based on the database, a type of vehicle data that corresponds to the type of the subject vehicle, and

the center-side checking section is configured to determine that “

the type of the vehicle data is appropriate”

on condition that the identified type of vehicle data agrees with the type of the vehicle data that has been prescribed as a subject to be collected to the subject vehicle.

3. The remote vehicle data collection system according to claim 2, wherein

the database is configured to associate a range of possible values of the vehicle data with the type of the vehicle data,

the center-side checking section is configured to identify, based on the database, a range of possible values of the vehicle data to be collected from the type of the subject vehicle, and

the center-side checking section is configured to determine that “

the conditional expression of the vehicle data is appropriate”

on condition that a data value range of the vehicle data that satisfies the conditional expression prescribed to the subject vehicle is within the identified range.

4. The remote vehicle data collection system according to claim 2, wherein

the database is configured to associate a settable range of the checking cycle with the conditional expression,

the center-side checking section is configured to identify, based on the database, the settable range of the checking cycle in the conditional expression that corresponds to the type of the subject vehicle, and

the center-side checking section is configured to determine that “

the checking cycle is appropriate”

on condition that the checking cycle prescribed to the subject vehicle is within the identified range.

5. The remote vehicle data collection system according to claim 2, wherein

the database is configured to associate a settable range of the sampling cycle with the type of the vehicle data,

the center-side checking section is configured to identify, based on the database, the settable range of the sampling cycle for the type of the vehicle data that corresponds to the type of the subject vehicle, and

the center-side checking section is configured to determine that “

the sampling cycle is appropriate”

on condition that the sampling cycle prescribed to the subject vehicle is within the identified range.

6. The remote vehicle data collection system according to claim 1, wherein

the subject vehicle has at least one of a memory and a storage, and

the resources of the subject vehicle checked by the vehicle-side checking section are configured to include an amount of space in at least one of the memory and the storage.

7. The remote vehicle data collection system according to claim 1, wherein

the subject vehicle has a vehicle network, and

the resources of the subject vehicle checked by the vehicle-side checking section are configured to include a bus occupancy of the vehicle network.

8. The remote vehicle data collection system according to claim 1, wherein a script that describes one or more commands is configured to designate a collection condition of the vehicle data.

9. The remote vehicle data collection system according to claim 1, wherein

the subject vehicle includes a plurality of vehicle mounted control devices, which are connected to a controller area network (CAN), and

one or more of the vehicle mounted control devices are configured to collect the vehicle data through communication specified by the CAN protocol.

10. A controlling method of a remote vehicle data collection system comprising a center that manages traveling information of a plurality of vehicles, wherein the method comprising:

by the center, prescribing to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression;

by the center, reading through wireless communication, the vehicle data collected based on the prescription;

by the center, including a check criterion and a center-side checking section;

by the center-side checking section, checking based on the check criterion, appropriateness of at least one of the type of the vehicle data, the conditional expression, the sampling cycle, and the checking cycle that is prescribed to the subject vehicle;

by the subject vehicle, including a vehicle-side checking section, which is configured to check whether resources of the subject vehicle are appropriate; and

by the vehicle-side checking section, checking whether the resources of the subject vehicle are appropriate when the vehicle data is collected based on the prescription from the center.
