Abstract

A center prescribes, to a subject vehicle, a collection condition for vehicle data through wireless communication. An instruction executing section reads in and executes an instruction described as the collection condition. A determination section determines whether environment information prescribed by the collection condition agrees with the vehicle environment of the subject vehicle. A communication section delivers, to the center, the vehicle data of a time at which the agreement is established.

Claims

1. A remote vehicle data collection system comprising a center, wherein

the center manages traveling information of a plurality of vehicles,

the center prescribes, to a subject vehicle, a collection condition for vehicle data through wireless communication,

in the subject vehicle, vehicle data is collected based on the collection condition,

the center is configured to read the vehicle data collected in the subject vehicle through wireless communication, the remote vehicle data collection system comprises, in the subject vehicle:

an instruction executing section, which is configured to read in and execute an instruction described as the collection condition, wherein the collection condition is interpreted as the instruction executing section executes the instruction, and the collection condition prescribes environment information,

a determination section, which makes determination on whether the environment information prescribed by the collection condition agrees with a vehicle environment of the subject vehicle, and

a communication section, which is configured to deliver, to the center, the vehicle data of a time at which the determination section determines that the agreement is established.

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

the vehicle data is accumulated in correspondence with the environment information,

a criterion for the environment information is determined in advance through statistical processing performed on the accumulated vehicle data, and

the determination section is configured to apply the criterion to newly obtained vehicle data to determine whether the environment information agrees with the vehicle environment of the subject vehicle.

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

vehicle data is accumulated in the subject vehicle, and

the criterion is determined based on the vehicle data accumulated in the subject vehicle.

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

the subject vehicle includes a vehicle mounted camera, which is configured to capture an image outside or inside the vehicle, and

the determination section is configured to use an image captured by the vehicle mounted camera to determine whether the environment information agrees with the vehicle environment of the subject vehicle.

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

the determination section includes an image processing section, which is configured to process an image captured, from outside, by the vehicle mounted camera, and

the image processing section is configured to process the image to determine whether the environment information agrees with the vehicle environment of the subject vehicle.

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, and

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

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

the center is configured to send a script including at least one of a checking cycle, a data collecting period, a sampling cycle, and data to be collected to the subject vehicle as the collection condition.
