Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an operation status notification system according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a vehicle, on which a shock detection device 2, an operation status storage device 3, a transmission unit 4, and an antenna 5 are mounted. The impact detection device 2
It detects an impact acting on the vehicle 1 when a failure occurs, and includes an acceleration detection unit 20, an impact time determination unit 21 shown in FIG.
And an acceleration determination unit 22.

An acceleration detecting section 20 shown in FIG. 2 detects an acceleration acting on the vehicle 1 and outputs a detection result as an acceleration detection signal S.
Output as 1. The impact time determination unit 21 outputs, as an impact time determination signal S2, an impact time during which an impact is applied to the vehicle 1 when a failure occurs. The acceleration determination unit 22 determines whether the acceleration and the impact time obtained from the acceleration detection signal S1 and the impact time determination signal S2 have exceeded a preset threshold. Specifically, when the acceleration and the impact time exceed the threshold values, the acceleration determination unit 22 determines that a failure has occurred, and instructs to save later-described operation situation data before and after the occurrence of the failure. The storage instruction signal S3 is output.

The operation status storage device 3 stores the operation status, and includes a storage unit 30, a storage control unit 31, and a storage storage unit 32. The storage unit 30 stores operation status data D0 input from various instruments in the vehicle 1. Here, the operation status data D0 includes data such as the speed of the vehicle 1, the method of acceleration, the steering angle of the steering wheel, the oil temperature, the water temperature, the oil pressure, the oil amount, and the water amount.

The operation status data D0 is stored in the sequential storage unit 3
0 is stored. When the operation status data storage instruction signal S3 is input, the storage control unit 31 stores the operation status data D0 before the failure and the operation status data D0 after the failure stored in the storage unit 30. 32. When the storage capacity of the storage unit 30 becomes full, the storage storage unit 32 performs write control on the storage unit 30 so that the old operation status data D0 is updated to the latest operation status data D0.

The transmitting unit 4 transmits the storage contents of the storage unit 32 (the operation status data D0 before and after the occurrence of the failure) as the operation status data D to the management station 6 shown in FIG. The management station 6 includes an antenna 7, a reception unit 8, an operation status analysis unit 9, and a status determination unit 10.

The receiving section 8 receives the operation status data D via the antenna 7. The operation status analysis unit 9 analyzes the status of the vehicle 1 based on the operation status before and after the occurrence of the failure obtained from the operation status data D. Situation judgment unit 10
Determines the degree of obstacle in the vehicle 1 from the analysis result of the operation status analysis unit 9.

Next, the operation of the operation status notification system according to the above-described embodiment will be described. In FIG.
Now, assuming that no trouble has occurred in the vehicle 1, the operation status data D0 is sequentially stored in the storage unit 30. Also,
An acceleration detection signal S1 indicating the acceleration acting on the vehicle 1 is output from the acceleration detection unit 20 to the acceleration determination unit 22, and an impact time determination signal S2 indicating the impact time is output from the impact time determination unit 21. Is output to the acceleration determination unit 22. In this case, assuming that the acceleration and the impact time do not exceed the threshold, the acceleration determination unit 2
2 does not output any signal.

If a fault such as a traffic accident occurs in the vehicle 1, the acceleration and the impact time acting on the vehicle 1 exceed the threshold value.
Transmits the operation status data storage instruction signal S3 to the storage controller 31.
Output to As a result, the storage control unit 31
From 0, the operation status data D0 before the occurrence of the failure and the operation status data D0 after the occurrence of the failure are read out, and these data are stored in the storage unit 32.

As a result, the transmitting unit 4 can store the
(Operation status data D0 before and after the occurrence of a failure) is transmitted as operation status data D via the antenna 5. Then, the operation status data D is received by the reception unit 8 via the antenna 7 of the management station 6, and then input to the operation status analysis unit 9. Thereby, the operation status analysis unit 9
Analyzes the status of the vehicle 1 based on the operation status before and after the occurrence of the failure obtained from the received operation status data D.
Next, the situation determination unit 10 determines the degree of the failure in the vehicle 1 from the analysis result of the operation situation analysis unit 9.

As described above, according to the operation status notification system according to the above-described embodiment, when a failure occurs in the vehicle 1, the operation status data D before and after the failure is automatically transmitted to the management station 6. With this configuration, it is possible to know an objective and accurate vehicle operation status required for verification after the occurrence of a failure in the vehicle 1.

Although the operation status notification system according to one embodiment of the present invention has been described in detail, the specific configuration is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. Even if present, it is included in the present invention. For example, in the operation status notification system according to the above-described embodiment, the operation status output unit 40 and the external terminal 41 may be provided in the vehicle 1 as shown in FIG. The operation status output unit 40 illustrated in FIG. 3 outputs the operation status data D stored in the storage storage unit 32 of the operation status storage device 3 to the external terminal 41. External terminal 41
Is connected to the operation status output unit 40 after the occurrence of a failure, and displays the operation status data D on a screen or stores it in its own storage medium.

[0016]

As described above, according to the present invention,
When a failure occurs in the vehicle, the operation status data is automatically transmitted to the receiving means of the management station, so the objective and accurate operation of the vehicle required for verification after the failure of the vehicle has occurred. The effect of being able to know the situation is obtained.
