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.

First claim

What is claimed is:

1. A remote vehicle data collection system, comprising:
A subject vehicle;
a center including a center processor that manages traveling information of a plurality of vehicles and a center memory/storage storing a program performed by the center processor, wherein
the center processor is configured to prescribe, based on an input from an external terminal, to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression with a determination factor used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression with the determination factor,
the center processor is configured to read, through wireless communication, the vehicle data collected based on the prescription,
the center processor includes a check criterion,
the center processor is configured to check, based on the check criterion, appropriateness of the at least one of the type of the vehicle data, the conditional expression with the determination factor, the sampling cycle, and the checking cycle that is prescribed to the subject vehicle and is set based on the input from the external terminal to collect the vehicle data,
the subject vehicle includes a vehicle electronic control unit (ECU) and a vehicle processor, which is configured to check whether resources of the subject vehicle are appropriate,
the vehicle processor 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, and
a lower limit of the sampling cycle is set for each item of the vehicle data to improve reliability of operation of the vehicle ECU of the subject vehicle, 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 processor 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 processor 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, wherein
the database is configured to associate a settable range of the checking cycle with the conditional expression with the determination factor,
the center processor is configured to identify, based on the database, the settable range of the checking cycle in the conditional expression with the determination factor that corresponds to the type of the subject vehicle, and
the center processor 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.

2. The remote vehicle data collection system according to claim 1 , 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 processor 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 processor is configured to determine that the conditional expression with the determination factor of the vehicle data is appropriate on condition that a data value range of the vehicle data that satisfies the conditional expression with the determination factor prescribed to the subject vehicle is within the identified range.

3. 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 processor are configured to include an amount of space in the at least one of the memory and the storage.

4. 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 processor are configured to include a bus occupancy of the vehicle network.

5. 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.

6. 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.

7. A remote vehicle data collection system, comprising:
a subject vehicle;
a center including a center processor that manages traveling information of a plurality of vehicles and a center memory/storage storing a program performed by the center processor, wherein
the center processor is configured to prescribe, based on an input from an external terminal, to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression with a determination factor used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression with the determination factor,
the center processor is configured to read, through wireless communication, the vehicle data collected based on the prescription,
the center processor includes a check criterion,
the center processor is configured to check, based on the check criterion, appropriateness of the at least one of the type of the vehicle data, the conditional expression with the determination factor, the sampling cycle, and the checking cycle that is prescribed to the subject vehicle and is set based on the input from the external terminal to collect the vehicle data,
the subject vehicle includes a vehicle electronic control unit (ECU) and a vehicle processor, which is configured to check whether resources of the subject vehicle are appropriate,
the vehicle processor 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, and
a lower limit of the sampling cycle is set for each item of the vehicle data to improve reliability of operation of the vehicle ECU of the subject vehicle, 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 processor 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 processor 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, wherein
the database is configured to associate a settable range of the sampling cycle with the type of the vehicle data,
the center processor 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
