Abstract

A vehicle data acquisition system that stores, in a memory device, vehicle data acquired by way of a vehicle-mounted information processor. A data acquisition program assisting the acquisition of the vehicle data is dynamically incorporated in the vehicle-mounted information processor. A probe section, which can be replaced with another command, is positioned as an invalid command in one or a plurality of positions in an application program incorporated in advance in the information processor. The data acquisition program replaces the probe section with a vehicle data acquisition command and stores the acquired vehicle data in chronological order in the memory device. The data acquisition program re-replaces the probe section with an invalid command after the vehicle data is acquired.

Claims

1. A vehicle data acquisition system configured to acquire vehicle data through an in-vehicle information processing device mounted on a vehicle, and store the acquired vehicle data in a storage device, the in-vehicle information processing device having incorporated therein in advance an information processing section that executes a process procedure of an information processing,

the vehicle data acquisition system comprising:

a data acquisition assisting section that is dynamically incorporated in the in-vehicle information processing device so as to assist acquisition of the vehicle data by utilizing an information processing operation state of the in-vehicle information processing device; and

a probe section that is arranged as an invalidation instruction at one or a plurality of positions where data acquiring process included in the process procedure is executed, wherein

the probe section is configured to be capable of being replaced with another instruction in accordance with a command from the data acquisition assisting section, and

by being incorporated into the in-vehicle information processing device, the data acquisition assisting section replaces the probe section with an acquiring instruction for the vehicle data, stores the vehicle data acquired by the replacement in the storage device in a chronological order, and re-replace the probe section with the invalidation instruction after having acquired the necessary vehicle data.

2. The vehicle data acquisition system according to claim 1, wherein the data acquisition assisting section determines whether or not to execute the replacement of the instruction in the probe section in accordance with a state of the vehicle.

3. The vehicle data acquisition system according to claim 2, wherein the data acquisition assisting section executes the replacement of the instruction in the probe section under a condition that the vehicle is at a halt.

4. The vehicle data acquisition system according to claim 1, wherein the data acquisition assisting section does not execute the replacement of the instruction in the probe section when it is predicted that a time required for information processing by the in-vehicle information processing device will exceed a specified time allocated to the information processing due to executing the replacement of the instruction in the probe section.

5. The vehicle data acquisition system according to claim 1, wherein

the probe section is one of a plurality of probe sections, and

the data acquisition assisting section executes the replacement of the instruction in selected one or more of the probe sections such that a time required for information processing by the in-vehicle information processing device does not exceed a specified time allocated to the information processing.

6. The vehicle data acquisition system according to claim 1, wherein the data acquisition assisting section does not execute the replacement of the instruction in the probe section when it is determined that the acquiring process to acquire the vehicle data via the probe section will give adverse influence on the information processing executed by the in-vehicle information processing device.

7. The vehicle data acquisition system according to claim 1, wherein the data acquisition assisting section does not execute the replacement of the instruction in the probe section when it is determined that the acquiring process to acquire the vehicle data via the probe section will not fulfill an execution condition in the in-vehicle information processing device.

8. The vehicle data acquisition system according to claim 1, wherein

an acquiring instruction for the vehicle data is prepared in the data acquisition assisting section in advance, and

the acquiring instruction is created such that a time required for information processing by the in-vehicle information processing device does not exceed a specified time allocated to the information processing.

9. The vehicle data acquisition system according to claim 1, wherein the data acquisition assisting section is dynamically incorporated into the in-vehicle information processing device via a wired communication or a wireless communication.

10. The vehicle data acquisition system according to claim 9, wherein

the in-vehicle information processing device is configured to execute the process procedure based on an information processing program that is stored in advance,

the probe section is incorporated as an invalidation instruction in the information processing program,

the data acquisition assisting section is implemented by an additional program that includes as a script an acquiring instruction for the vehicle data, the acquiring instruction being configured to be capable of being loaded to the in-vehicle information processing device and unloaded from the in-vehicle information processing device,

the probe section is replaced with the acquiring instruction for the vehicle data in response to loading of the additional program to the in-vehicle information processing device, and

the probe section is re-replaced with the invalidation instruction after having acquired the necessary vehicle data or in response to unloading of the additional program from the in-vehicle information processing device.

11. The vehicle data acquisition system according to claim 1, wherein

the vehicle data stored in the storage device is sent to an analysis center, and

the analysis center analyzes a state of the vehicle based on a change in the vehicle data.

12. The vehicle data acquisition system according to claim 11, wherein the vehicle data is sent to the analysis center from the storage device via a wireless communication.

13. A vehicle data acquisition method configured to acquire vehicle data through an in-vehicle information processing device mounted on a vehicle, and store the acquired vehicle data in a storage device, the in-vehicle information processing device having incorporated therein in advance an information processing section that executes a process procedure of an information processing,

the vehicle data acquisition method comprising:

an incorporating step for dynamically incorporating a data acquisition assisting section in the in-vehicle information processing device, the data acquisition assisting section being configured to assist acquisition of the vehicle data by utilizing an information processing operation state of the in-vehicle information processing device;

a replacing step for replacing, with an acquiring instruction for the vehicle data, a probe section arranged as an invalidation instruction at one or a plurality of positions where data acquiring process included in the process procedure is to be executed in response to incorporating of the data acquisition assisting section into the in-vehicle information processing device, wherein the probe section is configured to be capable of being replaced with another instruction in response to a command from the data acquisition assisting section;

a storing step for storing the vehicle data acquired by the replacement in the storage device in a chronological order; and

a re-replacing step for re-replacing the probe section with the invalidation instruction after having acquired the necessary vehicle data.

14. The vehicle data acquisition method according to claim 13, wherein, in the replacing step, a determination on whether or not to execute the replacement of the instruction in the probe section is made in accordance with a state of the vehicle.
