FIG. 6 is a diagram showing, in a table format, a data structure of data transmitted to the server by repeating the processing of the information processing method represented by the flowchart of FIG.

In the data structure 4 shown in FIG. 6, the following six types of information are associated with each other. That is, the six types of information include position information 41 indicating the traveling position of the moving body 1, driving support function information 42 indicating the driving support function being executed, and behavior information 43 indicating the behavior of the moving body 1. include. Further, the type information 44 of the maker/driving support program indicating the driving support program and the maker of the vehicle 1 or the type of the driving support program, the moving body type information 45 indicating the type of the moving body 1, and the version of the driving support program are displayed. The version information 46 shown is included. Then, the information set 47 including the above six types of information is transmitted to the server device 2 by the mobile communication means 113 one by one each time the processing of the information processing method represented by the flowchart of FIG. It

Explaining the example of FIG. 6, first, it is shown that the mobile body 1 of the mobile body type A1 manufactured by Company A and having the A program of Ver1.0 is traveling normally at the position Pt11 in the state where the driving support is not executed. The information set 47 is transmitted. After the transmission of the similar information set 47 continues, the execution of the ACC function is started at the position Pt12, and the information set 47 indicating that the vehicle is normally traveling under the ACC function at the position Pt12 is transmitted. Then, after the normal running under the ACC function continues in the section including the position Pt13, in the example of FIG. 6, the information set 47 indicating that the position Pt14 causes the sudden braking as the so-called near miss, which is a slight dangerous behavior. Will be sent. Transmission of the information set 47 indicating normal traveling continues after the position Pt15 in the next cycle, but at the stage of reaching the position Pt16, an information set indicating that sudden braking as a serious dangerous behavior due to the occurrence of a curb riding accident has occurred. 47 has been transmitted. The mobile unit 1 has stopped at this point, and the transmission of the information set 47 has also stopped here.

Although FIG. 6 shows an example of transmission of data having the data structure 4, such a series of data transmission is performed in each of the plurality of mobile bodies 1 shown in FIG. Based on the above, the data creation device 210 of the server device 2 creates map data.

Next, the data creation device 210 of the server device 2 will be described. The data creation device 210 is a device that creates map data of the data structure 3 shown in FIGS. 3 and 4 based on the information from the mobile unit 1, and as shown in FIG. The communication means 211 (acquisition means), the processing means 212, and the provision means 213 are provided. With these components, the data creation device 210 creates map data according to the flow of processing in the information processing method described below.

FIG. 7 is a flowchart showing the flow of processing of the information processing method performed in the server device shown in FIG.

This process starts when the server device 2 is powered on. Then, first, the server communication unit 211 associates the position information 41 indicating the traveling position, the driving support function information 42 being executed, and the like with respect to one of the plurality of moving bodies 1 with each other. The acquisition step (step S21) of acquiring the processed information is executed. In this acquisition step (step S21), the information set 47 corresponding to one row of the table shown in FIG. 6 is acquired as the processing target information from the mobile unit 1. That is, here, as the processing target information, the position information 41, the driving support function information 42, the behavior information 43, the maker/driving support program type information 44, the moving body type information 45, and the version information 46 of one mobile body 1 are processed. , Are obtained.

Next, based on the acquired information set 47, the processing means 212 executes the following safety point adjustment process (step S22). That is, the safety point adjustment process (step S22) is for evaluating the safety of the driving support function of the evaluation target associated with the position or area on the map to which the position information 41 of the mobile unit 1 in the information set 47 belongs. This is a process of adjusting the safety points of. The increase/decrease value of this safety point is determined based on the behavior information 43 of the mobile unit 1 in the information set 47 using the following evaluation table.

FIG. 8 is a diagram showing an evaluation table in which various behaviors of the mobile body are associated with the added/subtracted values of the safety points for evaluating the safety of the driving support function.

In the evaluation table 5 shown in FIG. 8, an increase/decrease value of plus N11 is associated with normal traveling, and an increase/decrease value of minus N12 is associated with sudden braking as a slight dangerous behavior equivalent to a near miss. .. In addition, the sharp steering wheel as the slightly dangerous behavior is associated with the addition/subtraction value of minus N13 which is approximately the same as the above-mentioned addition/subtraction value of minus N12. Further, the sudden braking, which is a seriously dangerous behavior associated with the occurrence of the curb riding accident, is associated with the adjustment value of minus N14, which has a larger absolute value than the above-mentioned adjustment value of minus N12 or minus N13. The evaluation table 5 is stored in the server storage device 220 shown in FIG.

In the safety point adjustment process (step S22) of FIG. 7, the processing unit 212 refers to the above-described evaluation table 5 and is associated with the behavior of the mobile body 1 indicated by the behavior information 43 in the acquired information set 47. Calculate the value of sex points. Then, the processing means 212 adjusts the safety points in association with the driving support function to be evaluated, using the obtained addition/subtraction value for the position or area in the map to which the positional information 41 in the information set 47 belongs.

In this way, when the acquisition step (step S21) and the safety point adjustment step (step S22) are executed for one information set 47, the processing means 212 causes the two steps to be executed over a certain period. It is determined whether it has been done (step S23). When the period is not yet reached (No determination in step S23), the process returns to step S21 and the subsequent processes are repeated. By repeating this, safety points for the driving support function and the like are accumulated at the position or area on the map. When the above-mentioned two processes are executed for a certain period (Yes determination in step S23), the processing unit 212 executes the following safety evaluation process (step S24). The safety evaluation step (step S24) is a step of statistically evaluating the safety of the driving support function with respect to the position or area on the map based on the cumulative value of the safety points.

FIG. 9 is a table showing an example of an evaluation result when the statistical safety of the driving support function is evaluated based on the cumulative value of safety points.

In the evaluation result table 6 shown as an example in FIG. 9, the evaluation result when the statistical safety for the driving support function 62 is evaluated for the position or area 61 on the map is shown in FIG. The map area Ar11 is shown as an example. In the evaluation here, first, when one information set 47 is acquired from one mobile body 1, the position or area 61 to which the position information 41 in the information set 47 belongs is obtained. Here, it is assumed that the position information 41 belongs to the area Ar11.

Next, in the area Ar11, the driving support function information 42 of the information set 47, the manufacturer/driving support program type information 44, the moving body type information 45, and the version information 46 are already evaluated as the driving support function information 62 and the manufacturer. /It is determined whether or not they are associated with each other as the type information 63, the moving body type information 64, and the version information 65 of the driving support program. When they are not associated with each other, each of the above information in the information set 47 is associated with the area Ar11 as an evaluation target. Further, the added/subtracted value of the safety point obtained based on the behavior information 43 in the information set 47 is associated with the region Ar11 as the initial value of the safety point.

On the other hand, when the above-mentioned various pieces of information in the information set 47 are already associated with the area Ar11 as an evaluation target, the safety point adjustment process (step S22) is performed as follows. First, based on the behavior information 43 of the mobile unit 1 in the information set 47, the increase/decrease value of the safety point is obtained. Next, the calculated addition/subtraction value is added to or subtracted from the safety points that are already associated with the evaluation target in the area Ar11.

The above processing is executed every time the information set 47 is acquired from each one mobile body 1 of the plurality of mobile bodies 1 within a certain period, and safety points are accumulated.

Then, after a certain period of time has passed, the processing unit 212 compares the cumulative value 66 of the safety points associated with the evaluation target position or area 61 on the map together with each evaluation target information with a predetermined threshold value. It If it is equal to or more than the threshold value, the evaluation result 67 shows the evaluation target driving support function with respect to the manufacturer of the evaluation target, the type of the driving support program, the type of the moving body, and the version in the position or the region (here, the region Ar11) 61. The execution of is statistically safe.

In the example of FIG. 9, in the area Ar11, the driving support by the ACC function should not be executed for the manufacturer corresponding to the cumulative value Cn11, Cn13 of the safety points, the type of the driving support program, the type of the moving body, and the version ( It is evaluated as (non-permitted). On the other hand, regarding the manufacturer corresponding to the cumulative value Cn12, Cn14, Cn15 of the safety points, the type of the driving support program, the type of the mobile body, and the version, it is evaluated that the driving support by the ACC function should be executed (permitted). ing.

In the safety evaluation step (step S24) in the flowchart of FIG. 7, when the evaluation shown as an example in FIG. 9 is performed, the map data creation step (step S25) based on the evaluation result is processed by the processing means 212. Done by In the map data creation step (step S25), the embedded information 310 (FIGS. 3 and 4) including the above evaluation result as the statistical information 314 is created for each position or area on the map such as the area Ar11 and the road link L11. Then, the created embedded information 310 is embedded in the map data of the data structure 3 shown in FIG. 3 by being associated again with the position or area corresponding to the evaluation result.

Subsequently, the storage means (step S26) for storing the map data created by such embedding in the server storage device 220 is performed by the processing means 212. After the storage step (step S26) ends, the process returns to step S21 and the subsequent processes are repeated. By repeating this, every time a certain period of time elapses, safety points are accumulated based on the information set 47 acquired from each one of the plurality of moving bodies 1 during that period, and the accumulated value thereof is calculated. Map data is created and stored based on the evaluation result for 66. That is, the map data of the server storage device 220 is updated at regular intervals by the processing of the information processing method according to the flowchart of FIG. 7. This map data is appropriately provided to the mobile unit 1 by the providing unit 213, and is referred to when the driving support function of the mobile unit 1 to which the map data is provided is determined.

In this embodiment, the processing of the information processing method represented by the flowchart of FIG. 7 continues to be executed until the power of the server is turned off.

The driving support function information 42 and the position information 41 in the moving body 1 are used to show how the driving support is actually performed at an arbitrary traveling position according to traveling conditions that change over time due to road construction or surrounding construction work, for example. It shows that I was broken. Such an information set 47 is transmitted from the mobile body 1 to the server device 2, and statistical information 314 corresponding to a position or area on a predetermined map indicating whether or not to execute the driving support function (permitted/not permitted) is displayed.
