(First Embodiment)
<1. Overview of data collection system>
First, the outline of the data collection system according to the first embodiment will be described with reference to FIGS. 1A to 1E. 1A to 1E are diagrams showing an outline of a data collection system according to the first embodiment.

As shown in FIG. 1A, the data collection system 1 according to the present embodiment includes the data collection device 10 and the in-vehicle devices 100-1, 100- mounted on the vehicles V-1, V-2, V-3, respectively. 2,100-3 ... And the user terminal 200 are included. In the following, the term "vehicle V" is used to refer to the vehicle in general, and the term "vehicle device 100" is used to refer to the vehicle-mounted device in general. Further, in the first embodiment, the case where the data search device according to the present application is included in the data collection device 10 will be described as an example.

Further, in the following, it is assumed that the vehicle V is an autonomous driving vehicle and the automatic driving control is performed by the vehicle control model mounted on each vehicle V, but the present invention is not limited to this.

The data collection device 10 is configured as a cloud server that provides cloud services via a network such as the Internet or a mobile phone network, and receives and receives a predetermined vehicle data collection request regarding the vehicle V from a data user. Vehicle data is collected from each in-vehicle device 100 based on the collection request. Then, the data collecting device 10 provides the collected vehicle data to the user.

The in-vehicle device 100 is a device having various sensors such as a camera, an acceleration sensor, a GPS (Global Positioning System) sensor, a vehicle speed sensor, an accelerator sensor, a brake sensor, and a steering angle sensor, a storage device, and a microcomputer. The in-vehicle device 100 acquires a collection instruction corresponding to the collection request received by the data collection device 10 from the data collection device 10, and collects (acquires) vehicle data from the vehicle V based on the collection instruction.

The above-mentioned camera can, for example, capture the surroundings of the vehicle V and output moving image data. The moving image data is an example of video data. Further, the video data is not limited to the moving image data, and may include still image data and the like.

Further, the acceleration sensor detects the acceleration acting on the vehicle V, and the GPS sensor detects the position of the vehicle V. The vehicle speed sensor detects the vehicle speed of the vehicle V. Further, the accelerator sensor detects the operation amount of the accelerator pedal, and the brake sensor detects the operation amount of the brake pedal. Further, the steering angle sensor detects the steering angle of the steering wheel of the vehicle V. As the in-vehicle device 100, for example, a drive recorder can be used.

Further, the in-vehicle device 100 appropriately uploads the collected vehicle data to the data collecting device 10. By using the drive recorder as the in-vehicle device 100 in this way, it is possible to improve the efficiency of the in-vehicle parts mounted on the vehicle V. The in-vehicle device 100 and the drive recorder may be separately configured without being shared.

The user terminal 200 is a terminal used by a data user, for example, a notebook PC (Personal Computer), a desktop PC, a tablet terminal, a PDA (Personal Digital Assistant), a smartphone, a glasses type or a clock type information processing. It is a wearable device that is a terminal. The user terminal 200 is an example of a terminal device, and the data user is an example of a user.

In the data collection system 1 according to the present embodiment, the data collection device 10 collects vehicle data from the in-vehicle device 100 and provides it to the user terminal 200 based on the collection conditions specified via the user terminal 200. Can be done. Then, the data user of the user terminal 200 can analyze the behavior of the vehicle V for which the vehicle data is collected, the event generated in the vehicle V, and the like by using the provided vehicle data.

Hereinafter, using FIGS. 1A to 1E, a series of flows until the vehicle data is provided to the data user in the data collection system 1 and a flow of the vehicle data search process will be described. As shown in FIG. 1A, the data user first specifies the collection conditions by the user terminal 200 connected to the data collection device 10. The user terminal 200 transmits a collection request including the specified collection conditions to the data collection device 10.

Here, the above-mentioned collection conditions include various parameters such as conditions that trigger collection, and an example of the conditions that trigger such collection is, for example, the case where the vehicle V travels in automatic driving. The conditions that trigger the collection described above are merely examples and are not limited. For example, when the vehicle V travels by manual driving instead of automatic driving, or when the vehicle speed exceeds a predetermined speed. Other conditions such as cases may be used.

Further, when the collection conditions are specified, the data collection device 10 is added to the actual data R (an example of vehicle data) to be collected, and is used as index data for searching the actual data R and grasping the outline. The data for generating the tag data T having the characteristics of is generated. That is, the tag data T is metadata in which the actual data R is converted into meta information. The data for generating the tag data T is generated based on the operation of the data user while using the program and the data for generation stored in the user terminal 200 or the data collecting device 10.

Then, the designated collection conditions and the generated data for generating the tag data T are stored in the data collection device 10. Further, the data collection device 10 generates a collection instruction according to the collection request including the collection condition, and distributes the collection instruction together with the data for generating the tag data T to the vehicle V to be collected, and the in-vehicle device 100 Is remembered in.

Next, as shown in FIG. 1B, each in-vehicle device 100 monitors the output data of various sensors, and when an event that satisfies the stored collection condition occurs (here, the vehicle V travels by automatic driving). ), The actual data R such as output data and moving image data based on the collection instruction is collected and stored in the storage device.

Each in-vehicle device 100 generates and stores the tag data T corresponding to the actual data R based on the stored tag data T generation data and the actual data R. Then, each in-vehicle device 100 uploads the tag data T to the data collecting device 10, and the data collecting device 10 stores the tag data T. At this time, the actual data R is not uploaded to the data collection device 10. That is, as shown in FIG. 1B, the data collecting device 10 is in a state of holding only the tag data T.

Subsequently, when the data user connects to the data collection device 10 by the user terminal 200 to confirm the collection status and collect the actual data R, the meta information based on the tag data T collected by the data collection device 10 Is displayed on the user terminal 200.

Then, as shown in FIG. 1C, when the data user wants to collect and transmit predetermined actual data R (vehicle data, for example, moving image data), the user terminal 200 sets the collected actual data R to the actual data R. Specify the corresponding tag data T. As a result, the user terminal 200 outputs a transmission request for predetermined actual data R (vehicle data) to the data collection device 10. Then, the data collecting device 10 outputs a transmission instruction of the actual data R (in other words, instruction data for designating the actual data R) in response to the transmission request to the corresponding in-vehicle device 100.

After that, as shown in FIG. 1D, the designated actual data R is transmitted (uploaded) from each in-vehicle device 100 to the data collecting device 10 based on the transmission instruction, and stored in the data collecting device 10. Then, the data user accesses the actual data R stored in the data collecting device 10 by the user terminal 200, and the actual data such as viewing or downloading the actual data R is viewed from the data collecting device 10 to the user terminal 200. The transmission process of R is performed.

From the viewpoint of the data capacity of the in-vehicle device 100, the actual data R uploaded to the data collecting device 10 and the tag data T corresponding thereto are deleted from the in-vehicle device 100 after being uploaded to the data collecting device 10. Is preferable.

Further, the tag data T is not data that is simply an excerpt of a part of the actual data R, but can grasp the outline of the actual data R when the data user refers to it and determine the necessity of the actual data R. It is preferable that it is meta-informatized to some extent.

By the way, the number of actual data R (vehicle data) collected by the in-vehicle device 100 becomes enormous. Therefore, in the data collecting device 10 according to the present embodiment, for example, an appropriate actual data R desired by a data user can be efficiently searched from a huge amount of actual data R collected by the in-vehicle device 100. I made it possible.

Explaining with reference to FIG. 1E, for example, the data user can specify the search condition by the user terminal 200. Here, in the user terminal 200, vehicle state information indicating a predetermined vehicle state can be specified as a search condition.

For example, in the user terminal 200, a vehicle state in which the vehicle V is automatically driving, a vehicle state in which the vehicle V is traveling in a predetermined traveling place, and the like can be specified as search conditions, but the search conditions are not limited to these. That is, for example, when the vehicle data collected by the in-vehicle device 100 has already been transmitted from the data collecting device 10 to the user terminal 200, the user terminal 200 has video data indicating the vehicle state included in the vehicle data. (Movie data) 210 and graph 220 showing the vehicle state can be specified as search conditions.

Then, the data collecting device 10 sets the vehicle state information indicating the vehicle state as described above as a search condition. The data collecting device 10 performs a search process for searching the corresponding vehicle data corresponding to the search condition from the vehicle data collected by the vehicle-mounted device 100.

For example, when the vehicle state in which the vehicle V is traveling in automatic driving is set as a search condition, the data collecting device 10 collects vehicle data collected by the in-vehicle device 100 of the vehicle V traveling in automatic driving. Search and extract as compatible vehicle data.

Further, for example, the data collecting device 10 performs image analysis of the video data 210 when the video data 210 indicating the vehicle state is set as the detection condition. Based on the result of the image analysis, the data collecting device 10 calculates the characteristics of the video data 210 including, for example, the number of lanes, the presence / absence of a vehicle in front, the weather, and the like. Then, the data collecting device 10 searches for and extracts the corresponding vehicle data based on the calculated characteristics of the video data 210.

Further, for example, the data collecting device 10 analyzes the shape of the graph 220 when the graph 220 showing the vehicle state is set as the detection condition. The data collecting device 10 calculates the characteristics of the graph 220, such as a mountain shape, a valley shape, a rising right, and a rising left, based on the result of the analysis of the shape of the graph 220. Then, the data collecting device 10 searches for and extracts the corresponding vehicle data based on the calculated characteristics of the graph 220.

Then, the data collecting device 10 transmits the search result indicating the corresponding vehicle data searched and extracted to the user terminal 200. When the corresponding vehicle data of the search result is specified in the user terminal 200, the data collection device 10 performs a process of transmitting the corresponding vehicle data to the user terminal 200, such as viewing or downloading the corresponding vehicle data.

As described above, the data collecting device 10 according to the present embodiment sets the vehicle state information indicating the vehicle state as the search condition, and from the vehicle data collected by the in-vehicle device 100, the corresponding vehicle data corresponding to the search condition. I tried to search for.

Thereby, in the present embodiment, it is possible to efficiently search for, for example, appropriate vehicle data desired by the data user from the enormous amount of vehicle data collected by the in-vehicle device 100.

That is, the collection condition information DB 12a includes past results regarding the collection conditions.

The collection conditions include various parameters related to the collection of vehicle data. For example, various parameters include the identifier of the target vehicle V, the type of data to be collected, the conditions that trigger the collection, the collection period, and the like. As an example of the condition that triggers the collection, there is a case where the vehicle V travels by automatic driving, and more specifically, a case where the automatic driving is canceled and the automatic driving is executed.

In the collected data DB 12b, the collected data collected from each in-vehicle device 100 by the collecting unit 13c described later is accumulated. That is, the collected data DB 12b includes the past results of the collected data. The collected data includes the above-mentioned tag data T, actual data R, and the like.

Here, the collected data DB 12b will be described with reference to FIG. FIG. 4 is a diagram showing an example of the collected data DB 12b. As shown in FIG. 4, the collected data DB 12b contains "tag ID", "vehicle ID", "vehicle type", "position", "date and time", "weather", "driving mode", "video data", and , "Operating status" and other items are included.

The "tag ID" is identification information that identifies the tag data T. The "vehicle ID" is identification information that identifies the vehicle V. The "vehicle type" is information indicating the vehicle type of the vehicle V. In the example shown in FIG. 4, for convenience, the "vehicle type" is abstractly described as "vehicle type B1", but specific information is stored in the "vehicle type B1". Hereinafter, other information may be described abstractly.

The "position" is information indicating a position where the collection condition is satisfied and the collection of vehicle data is started, or a position where the vehicle V has traveled. The "date and time" is information indicating the time when the collection condition is satisfied and the collection of vehicle data is started. The "weather" is information indicating the weather at the position where the vehicle V has traveled. The "driving mode" is information indicating whether the vehicle V is in the automatic driving mode or the manual driving mode.

The "moving image data" is information indicating moving image data captured by a camera. The "driving state" is information indicating the driving state of the vehicle V, and is information indicating various driving states such as the vehicle speed, the operation amount of the accelerator and the brake, and the steering angle. In the collected data DB 12b, some information such as "position" and "weather" may be information collected from an external server.

In the example shown in FIG. 4, the data identified by the tag ID "T1" has a vehicle ID of "A01", a vehicle type of "vehicle type B1", a position of "position C1", a date and time of "date and time D1", and a weather of "date and time D1". It indicates that "weather E1", the driving mode is "automatic driving mode", the moving image data is "moving image F1", and the driving state is "driving state G1".

Returning to the description of FIG. 3, the search condition DB 12c stores, for example, the search condition specified by the user terminal 200 and set by the setting unit 13e described later.

Here, the search condition DB 12c will be described with reference to FIG. FIG. 5 is a diagram showing an example of the search condition DB 12c. As shown in FIG. 5, the search condition DB 12c includes items such as "search condition ID" and "search condition".

The "search condition ID" is identification information that identifies the search condition. The "search condition" is information indicating a search condition for vehicle data. The search condition includes the vehicle state information indicating the predetermined vehicle state described above. Specifically, the search conditions include a vehicle state in which the vehicle V is automatically driven, a graph 220 showing the vehicle state, video data (video data) 210 showing the vehicle state, a traveling place, a traveling date and time, and a general road.・ Road types such as expressways, vehicle types, weather, etc., but these are merely examples and are not limited.

Returning to the description of FIG. 3, the control unit 13 is a controller, and is stored in a storage device inside the data collection device 10 by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). It is realized by executing various programs in RAM as a work area. Further, the control unit 13 can be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The control unit 13 includes a reception unit 13a, a distribution unit 13b, a collection unit 13c, a provision unit 13d, a setting unit 13e, and a search unit 13f, and realizes the functions and operations of information processing described below. Execute.

The reception unit 13a receives the collection conditions specified from the user terminal 200 by the data user via the communication unit 11 and notifies the distribution unit 13b. In addition, the reception unit 13a stores the collection conditions specified by the data user in the collection condition information DB 12a.

In addition, the reception unit 13a receives a collection request including collection conditions and a transmission request of actual data R (vehicle data) from the user terminal 200 via the communication unit 11. The reception unit 13a notifies the distribution unit 13b and the collection unit 13c of the received collection request and transmission request.

The distribution unit 13b is stored in the collection condition information DB 12a, and distributes the collection conditions specified by the data user to the target vehicle V via the communication unit 11 in a file format, for example. For example, when the collection request is notified, the distribution unit 13b generates a vehicle data collection instruction in response to the collection request, and sends the generated vehicle data collection instruction to the vehicle-mounted device 100 of the vehicle V via the communication unit 11. Output (deliver).

When the reception unit 13a notifies the collection unit 13c of the transmission request of the actual data R, the collection unit 13c transmits the transmission instruction of the actual data R in response to the transmission request to the in-vehicle device 100 via the communication unit 11.

Further, the collecting unit 13c is vehicle data acquired (collected) based on the collection conditions distributed by the distribution unit 13b, and is the tag data T uploaded from the in-vehicle device 100 and the in-vehicle device in response to the transmission request. The actual data R uploaded from 100 is collected via the communication unit 11 and stored in the collected data DB 12b as collected data.

The providing unit 13d provides the collected data accumulated in the collected data DB 12b to, for example, the user terminal 200 via the communication unit 11. For example, the providing unit 13d provides the designated actual data R to the user terminal 200. Specifically, the providing unit 13d transmits and provides the actual data R transmitted and collected from the in-vehicle device 100 to the user terminal 200.

Here, the user terminal 200 in which the actual data R is provided and displayed will be described with reference to FIG. 6A. FIG. 6A is a diagram showing an example of the display unit (screen) 203 of the user terminal 200 on which the actual data R is displayed.

As shown in FIG. 6A, the display unit 203 of the user terminal 200 displays video data (video data) 210, graph information 220, map information 230, display setting field 240, data search button 250, and the like. ..

The video data 210 is data included in the actual data R, and is data obtained by imaging the surroundings of the vehicle V. The graph information 220 is data included in the actual data R, and is information indicating the vehicle speed, accelerator, brake, steering angle, and the like of the vehicle V. Note that, in FIG. 6A, the vehicle speed, accelerator, brake, and steering angle are shown as graph information 220, but these are merely examples and are not limited. The map information 230 is data included in the actual data R, and is information indicating the position of the vehicle V on the map and the like.

The display setting field 240 is a display field for setting information to be displayed on the user terminal 200. In the example shown in FIG. 6A, "display only the automatic driving section" can be set by a check box in the display setting field 240, and "display only the automatic driving section" is set by the data user. Therefore, only the actual data R collected in the automatic operation section is displayed on the user terminal 200.

If there is a level in automatic driving (a level depending on the degree of automatic driving such as fully automatic driving, automatic control of only specific operations such as emergency braking operation, etc.), a setting that specifies the automatic driving level is also an effective method.

The data search button 250 is a button that is pressed when the data user desires to search the actual data R. For example, when the data search button 250 is pressed, the setting unit 13e and the search unit 13f shown in FIG. 3 start the search process of the actual data R. The search process for the actual data R is not limited to the "exact match search" and the "partial match search" for searching the actual data R that matches the search conditions, but also for the actual data R similar to the search conditions. "Similar search" may be included.

More specifically, the search process of the actual data R described above can be described in detail. The setting unit 13e can set the vehicle state information indicating a predetermined vehicle state as a search condition. For example, the search condition set by the setting unit 13e may be the search condition specified by the user terminal 200.

The setting of such a search condition will be described with reference to FIG. 6B. FIG. 6B is a diagram showing an example of the search condition setting screen 270 displayed on the display unit 203 of the user terminal 200.

For example, the input information input to the search condition setting screen 270 shown in FIG. 6B is the search condition specified by the user terminal 200, and thus the setting unit 13e sets such input information as the search condition.

Specifically, on the search condition setting screen 270, a driving mode setting field 271, a driving place setting field 272, a driving date and time setting field 273, a road type setting field 274, a vehicle type setting field 275, a weather setting field 276, and the like are displayed. ..

In the operation mode setting field 271, an operation mode as a search condition can be set. In the example of FIG. 6B, the "automatic operation mode" and the "manual operation mode" can be set in the operation mode setting field 271.

The travel location setting field 272 can set a travel location as a search condition. In the example of FIG. 6B, the travel location setting field 272 is a column in which the travel location is input by the data user, a column for inputting the travel location from the map, and the reference actual data R (for example, with the information shown in FIG. 6A). Includes a column for specifying the same driving route as.

In the travel date / time setting field 273, the travel date / time as a search condition can be set. In the road type setting field 274, the road type as a search condition can be set. In the example of FIG. 6B, "general road" and "expressway" can be set in the road type setting field 274.

In the vehicle type setting field 275, a vehicle type can be set as a search condition. In the example of FIG. 6B, in the vehicle type setting column 275, "vehicle type XXX", "vehicle type YYY", "light vehicle", "ordinary vehicle", "large vehicle" and the like can be set.

In the weather setting field 276, the weather can be set as a search condition. In the example of FIG. 6B, "sunny", "rain", "snow" and the like can be set in the weather setting column 276. It should be noted that the setting contents of the above-mentioned search conditions are merely examples and are not limited.
