Description

The present invention relates to an information processing device , an information processing method , and a program.

Conventionally, vehicle-mounted devices for acquiring information about automobiles have been widely used. Information acquired by the on-board device is used to prevent automobile accidents.

In order to prevent automobile accidents, it is necessary to predict whether the automobile will cause an accident based on the information acquired by the vehicle-mounted device. For example, Patent Literature 1 is configured to determine the presence or absence of an abnormality in an automobile based on changes in acceleration detected by an acceleration sensor arranged in the automobile.

Retable 2016-038707

In general, the presence or absence of an abnormality in a mobile object may not depend on changes in the acceleration of the mobile object. For example, when the slope of the road on which the mobile body is running changes, the acceleration changes even though the mobile body does not have an abnormality.

In Patent Document 1, the presence or absence of an abnormality in the vehicle is determined based on changes in acceleration, so even if the vehicle does not have an abnormality, it may be determined to be "abnormal".

As described above, conventionally, the state of the moving object is determined based on the change in acceleration, so the accuracy of determination of the state of the moving object is not sufficient.

An object of the present invention is to improve the accuracy of determination of the state of a moving object.

One aspect of the present invention is
A means for obtaining speed information about the speed of the moving body,
A means for acquiring gravity load information about the gravity load applied to the moving body,
means for specifying a first period in which the speed of the moving object satisfies a predetermined speed condition based on the speed information;
means for calculating a gravity load for a second time period prior to the first time period based on the gravity load information indicated by the gravity load information;
comprising means for determining the state of the moving object based on the gravitational load during the second period;
It is an information processing device.

ADVANTAGE OF THE INVENTION According to this invention, the precision of determination of the state of a mobile body can be improved.

FIG. 11 is an explanatory diagram of acceleration during the second period of the present embodiment. FIG. 12 is an explanatory diagram of the angular velocity during the second period of this embodiment.

A client device 10a in FIG. 7 is a device that is placed in the mobile body MB and used by the driver of the mobile body MB. The client device 10b is a device arranged outside the mobile object MB and corresponding to the contact information associated with the driver identification information of the driver.

As shown in FIG. 7, the client device 10 acquires driver identification information (S110).
Specifically, processor 12 displays screen P10 (FIG. 7) on the display.

Screen P10 includes an operation object B100 and a field object F100.
The field object F100 is an object that receives input of driver identification information.
The operation object B100 is an object that receives a user instruction for finalizing the input of the field object F100.

After step S110, the client device 10 acquires travel information (S111).
Specifically, when the driver inputs his/her own driver identification information to the field object F100 and operates the operation object B100, the processor 12 controls each sensor (the acceleration sensor 21, the angular velocity sensor 22 and the position sensor 23) to acquire travel information (speed information, angular velocity information, and position information).
The processor 12 calculates the velocity of the mobile object MB based on the amount of change per unit time (that is, the movement distance) of the position indicated by the position information.

Processor 12 sends the following information to server 30 .
・Driver identification information input to the field object F100 in step S110 ・Running information (speed information, acceleration information, angular velocity information, and position information) acquired in step S111
・Date and time information regarding the execution date and time of step S111

After step S111, the server 30 updates the database (S130).
Specifically, the processor 32 adds a new record to the travel log information database (FIG. 5) associated with the driver identification information transmitted in step S111. Each field in the new record contains the following information:
- New travel log identification information is stored in the "travel log ID" field.
- The date and time information transmitted in step S111 is stored in the "date and time" field.
- The speed information transmitted in step S111 is stored in the "speed" field.
- The acceleration information transmitted in step S111 is stored in the "acceleration" field.
- The angular velocity information transmitted in step S111 is stored in the "angular velocity" field.
- The position information transmitted in step S111 is stored in the "position" field.

After step S130, the server 30 performs state determination (S131).
Specifically, the storage device 31 stores a state determination model (FIG. 8). The state determination model is configured to, when receiving at least one of acceleration information and angular velocity information for a predetermined period of time, output state information about the state of the moving body for that period of time.
The processor 32 determines the state of the moving object during the period by inputting the travel information included in the determination request data into the state determination model.

A detailed flow of step S131 will be described.

As shown in FIG. 9, the server 30 identifies the first period (S1310).
Specifically, as shown in FIG. 10, processor 32 refers to the travel log information database (FIG. 5) updated in step S130 to identify a first period that satisfies at least one of the following speed conditions: do.
・Period PER1a during which the state in which the velocity V is substantially zero continues
・Period PER1b during which the state in which information on velocity V is missing continues
In other words, the server 30 identifies the first period based on the change in speed over time.

After step S1310, the server 30 performs calculation of the gravity load for the second period (S1311).
Specifically, processor 32 identifies a predetermined period of time (for example, 10 seconds) before the first period of time identified in step S1310 as the second period of time. As an example, as shown in FIG. 10, the following period is identified as the second period.
The second period PER2a before the first period PER1a in which the velocity V remains substantially zero
・Second period PER2b before first period PER1b in which the lack of information on velocity V continues

Processor 32 refers to the information in the "date and time" field of the travel log information database (FIG. 5) updated in step S130, and identifies the record corresponding to the second period (hereinafter referred to as "second period record"). .

In the first example of step S1311, as shown in FIG. 11, the processor 32 refers to the "acceleration" field of the second period record to calculate the acceleration Ga(T) for the second period.

In a second example of step S1311, as shown in FIGS. 12A to 12C, the processor 32 refers to the “angular velocity” field of the second period record to calculate the angular velocity Gω(T) for the second period.

After step S1311, the server 30 performs state determination (S1312).
Specifically, the processor 32 determines the state of the moving body MB based on the gravitational load (at least one of the acceleration Ga(T) and the angular velocity Gω(T)) during the second period calculated in step S1311.

In the first example of step S1312, the processor 32 determines that an abnormality caused by the behavior of the moving body MB has occurred when the acceleration Ga(t) in the second period is equal to or greater than the predetermined acceleration threshold.

In the second example of step S1312, the processor 32 determines that an abnormality caused by the attitude of the moving body MB has occurred when the angular velocity Gω(t) in the second period is equal to or greater than a predetermined angular velocity threshold.
As an example, processor 32 compares any of the following values with an angular velocity threshold.
・Vector quantity of composite vector of angular velocity Gω(t) in second period ・Change rate of Z component of angular velocity Gω(t) in second period ・At least X component and Y component of angular velocity Gω(t) in second period one

In the third example of step S1312, the processor 32 determines that the acceleration Ga(t) during the second period is equal to or greater than the predetermined acceleration threshold, the angular velocity Gω(t) during the second period is equal to or greater than the predetermined angular velocity threshold, and If the position indicated by the position information in the second period indicates a position other than the travel route, it is determined that an abnormality has occurred due to the travel route of the moving body MB.

After step S1312, the server 30 updates the database (S1313).
Specifically, the processor 32 stores the determination result of step S1312 (for example, status information "abnormal" or "normal") in the "status" field of the second period record of the travel log information database (Fig. 5). .

After step S131, the server 30 performs notification (S132).
Specifically, the processor 32 refers to the driver information database (FIG. 4) to identify information regarding the driver name and contact information associated with the driver identification information transmitted in step S111.
Processor 32 transmits notification data to client device 10b corresponding to the contact information. Notification data includes the following information:
・Information about the identified driver name ・Date information sent in step S111 ・Location information sent in step S111 ・Abnormal message information about the status information determined in step S131

The processor 12 of the client device 10b displays the screen P11 (FIG. 7) on the display.

The screen P11 includes a display object A111.
The display object A111 displays information included in the notification data (information on the driver's name, date and time information, position information, and error message information).

According to this embodiment, the state of the mobile object MB is determined based on the combination of velocity information and angular velocity information. This makes it possible to more accurately determine the state of the mobile object MB (in particular, the presence or absence of an abnormality).

Further, according to this embodiment, the determination result of the state of the mobile object MB is notified to the destination specified by the contact information. Thereby, the state of the mobile body MB can be notified in real time to the outside of the mobile body MB.
