  However, if it is assumed that the subject actually drives the vehicle in order to analyze the driving skill of the subject, the analysis or the like is difficult for the subject who is not able to fully demonstrate the driving skill in the first place. There is a possibility. Moreover, if only a virtual driving scene is displayed, a deviation from the scene where the subject actually drives the vehicle may occur, which may reduce the evaluation accuracy of the driving ability of the subject.

  Therefore, an object of the present invention is to provide a system and a method that can improve the evaluation accuracy of the driving ability of a vehicle while expanding the width of an evaluation target person.

  The driving ability evaluation system of the present invention is a driving ability evaluation system for evaluating the driving ability of a subject's vehicle, in order to evaluate each of the subject's higher brain function and body function in a plurality of situations. An output interface for sequentially outputting each of a plurality of evaluation item groups corresponding to each of the plurality of situations, each of which is composed of one or a plurality of evaluation items, according to a first designated order; and output by the output interface And an input interface for allowing an evaluator to input an evaluation result for each evaluation item that constitutes each of the plurality of evaluation item groups, and the plurality of situations are determined by the subject person with respect to the vehicle. A first situation group consisting of one or more situations that are in contact with each other, and the subject is actually in contact with the vehicle in a stopped state A second status group consisting of one or more conditions are included, wherein the subject is a situation that is not actually driving the vehicle.

According to the driving ability evaluation system of the present invention, each of a plurality of evaluation item groups corresponding to each of a plurality of situations is sequentially output according to the first designation order. The “first designation order” determines the output order through the output interfaces of the plurality of evaluation item groups G ₁ , G ₂ ,. For example, the first order specified, G ₂ → G ₁ → If defining an output order of the evaluation item group that ‥, one or more evaluation constituting the evaluation item group G ₂ item g _21, g _22, ‥ of Each means that it is output before any one or a plurality of evaluation items g ₁₁ , g ₁₂ ,... Constituting the evaluation item group G ₁ . And about each of several evaluation item groups, each evaluation result of a subject's higher-order brain function and body function is input sequentially according to a 1st designation | designated order.

  “Input” includes contact input such as manual input, and non-contact input such as voice input or line-of-sight detection. “Output” means that the user outputs information in a form recognizable through the five senses such as vision and hearing. The “evaluation item group” includes one or a plurality of evaluation items for evaluating each of the higher brain function and the physical function of the subject. One or more evaluation items that make up one evaluation item group and one or more evaluation items that make up another evaluation item group may be completely different or may partially match Good.

  The “plurality of situations” is a situation where the target person is not actually driving the vehicle. Even if the subject is poor or lacking in driving ability to drive the vehicle, the driving ability is accurately evaluated, and as a result, the width of the subject is expanded. Further, the plurality of situations include a first situation group and a second situation group. The “first situation group” includes one or a plurality of situations in which the target person is virtually in contact with the vehicle, for example, realized by a drive simulator. The “second situation group” includes one or a plurality of situations in contact with the vehicle such as a situation in which the subject person can actually get on and off the vehicle in a stopped state or a situation in which the subject person is getting on the vehicle. The target in both the situation where the subject is actually in contact with the vehicle in the situation constituting the first situation group and the scene where the subject is actually in contact with the vehicle in the situation constituting the second situation group Since the higher brain function and body function of the person are evaluated, the evaluation accuracy of the driving ability of the subject can be improved.

The “second designation order” is an input of evaluation results e (g _q1 ), e (g _w2 ),... For the evaluation items g _q1 , g _w2 , etc. constituting the at least one evaluation item group G _q. It defines the order of input through the interface. For example, if the second designation order defines an input order of e (g _q1 ) → e (g _w2 ) →..., Evaluation is performed before the evaluation result e (g _q1 ) for the evaluation item g _q1 is input. This means that the input of the evaluation result e (g _w2 ) for the item g _q2 is not allowed.

  In the driving ability evaluation system of the present invention, when a second designated operation is performed through the input interface, the input interface displays a second evaluation result for each of the plurality of evaluation items constituting the at least one evaluation item group. It is preferable to enable input according to the specified order.

According to the driving ability evaluation system having the above configuration, an evaluation item that allows an evaluation result to be input through the input interface for each of the at least one evaluation item group output through the output interface each time there is a second designated operation through the input interface. Are switched in accordance with the second designation order. The “second designation operation” is, for example, when the second designation order defines an input order of e (g _q1 ) → e (g _w2 ) →... Evaluation result e (g _q1 ) for the evaluation item g _q1 Is an operation for switching the state in which the input of the evaluation result e (g _q2 ) to the evaluation item g _q2 is allowed to be input.

(How to use the driving ability evaluation system)
According to the driving ability evaluation system, for example, each of the higher-order brain function and body function of the subject is evaluated according to the order shown in FIG. Here, “i” is a “reference index” for identifying each i-th situation group. “I (i)” is an index for determining each order of the i-th situation group. “J _i ” is a “primary index” for identifying the situation constituting the i-th situation group or the evaluation item group corresponding thereto and defining the “first designation order”. “K _ij ” is a “secondary index” for identifying each evaluation item constituting the j _i evaluation item group and defining a “second designation order”.

Evaluation for each evaluation item g _3jk of the third evaluation item group G ₃ corresponding to the third situation group (i = I (1) = 3) → corresponding to the first situation group (i = I (2) = 1) order evaluation, that for each evaluation item g _JK second evaluation item group corresponding to the first evaluation item evaluation → second status group for each evaluation item g _1Jk of group (i = I (3) = 2) to Accordingly, each of the higher brain function and body function of the subject is evaluated (see FIG. 3 / black arrow). The order is I (1) = 3 → I (2) = 1 → I (3) = 2, I (1) = 1 → I (2) = 2 → I (3) = 3, I (3 1) = 1 → I (2) = 3 → I (3) = 2 may be changed in an arbitrary order.

In addition, with respect to the j _i evaluation item group G _ij constituting the i th situation group, each of the subject's higher brain function and body function is evaluated according to the “first designation order” of G _i1 → G _i2 →. (See Figure 3 / grey arrow). In addition, for the first k _ij evaluation item g _ijk that make up the first j _i evaluation item group _{G ij, g i11 → g i12} → ‥ g i21 → g i22 → ‥ g iNi1 → g iNi2 → "the second specified order" that ‥ Each of the subject's higher brain function and body function is evaluated according to (see FIG. 3 / white arrow).

(Function)
The operation or function of the driving ability system configured as described above will be described. Arithmetic processing in the server 1 is executed by the arithmetic processing device 14, and arithmetic processing in the client 2 is executed by the arithmetic processing element 24.

In the client 2, when predetermined application software (application) for executing the driving ability evaluation is activated through the input interface 21, the reference index i for identifying each i-th situation group is “I (i)”. ”(I (i) = 1,2,3), and a primary index j _i (j _i = 1,2) for identifying the situation constituting the i-th situation group or the evaluation item group corresponding thereto. ,... Is set to “1” and the secondary index k _ij (k _ij = 1, 2,...) For identifying each evaluation item constituting the j _i evaluation item group is set to “1”. It is set (FIG. 2 / STEP 201). The primary index j _i is an index that defines a “first designation order”, and the secondary index k _ij is an index that defines a “second designation order”.

  The “first situation group” is configured by one or more situations in which the subject person is virtually in contact with the vehicle 4. The “second situation group” is configured by one or a plurality of situations in which the target person is actually in contact with the stopped vehicle 4. The “third situation group” is configured by one or a plurality of situations in which the subject person is not in contact with the vehicle 4 virtually or actually. Each of the first, second, and third situation groups is a situation in which the person to be evaluated for driving ability does not actually drive and drive the vehicle 4.

In response to this, or in response to a trigger operation through the input interface 21, the j _{i th} evaluation item group is output through the output interface 22 (FIG. 2 / STEP 202). The “evaluation item group” includes one or a plurality of evaluation items for evaluating each of the higher brain function and the physical function of the subject. Thereby, for example, images as shown in FIGS. 4A and 4B are output through the output interface 22. In the image of FIG. 4A, a display field W0 of “the subject confirms front, side, and diagonally behind in the vehicle”, “side mirror adjustment”, “room mirror adjustment”, “power window open / close”, etc. Evaluation item display field W1 and evaluation result display field W2. In the image of FIG. 4B, a display column W0 for a situation in which “the subject confirms the four corners of the vehicle inside and outside the vehicle”, an evaluation item display column W1 such as “confirm the four corners of the vehicle (inside the vehicle)”, and an evaluation result display Column W2 is included. The evaluation items in the evaluation item display field W1 may be arranged in a certain direction according to the second designation order, and the arrangement order may be different from the second designation order (FIG. 4A and FIG. 4B).

  Each of Tables 1 to 7 shows a plurality of examples of evaluation item groups corresponding to one situation and evaluation viewpoints of the respective evaluation items.

  Each of the plurality of situations illustrated in each of Tables 1 to 7 may constitute a second situation group. For example, when a simulator that reproduces the driver's seat of the vehicle 4 is used, At least one of the situations may constitute the first situation group.

Then, among the one or more evaluation items constituting the first j _i endpoint group, for the k _ij endpoint g _ijk, is possible to input evaluation result through an input interface 21 (FIG. 2 / STEP 204) . In other words, at this stage, according to the second designation order, the evaluation result input through the input interface 21 is not allowed for the evaluation items whose order is later than the k _ij evaluation item g _ijk in the j _i evaluation item group.

Further, for the k _ij evaluation item g _ijk, it is determined whether or not an evaluation result is input through the input interface 21 (FIG. 2 / STEP 206). For example, in the evaluation result display field W2 of FIGS. 4A and 4B, the evaluation results of a plurality of stages (in this embodiment, the three-stage evaluation results represented by “」 ”,“ ◯ ”, and“ Δ ”) are the corresponding evaluation viewpoints. Is input to the client 2 by the evaluator. An evaluation result may be input by a touch operation or a keyboard operation of a touch panel constituting the input interface 21, or an evaluation result may be input by a selection operation from a pull-down menu Q1 displayed in the evaluation result display field. .

  The evaluation result input through the input interface 21 is output through the output interface 22 as a primary evaluation result. As a result, for example, as shown in FIG. 4A, the evaluation result display field W2 displays the evaluation results of a plurality of stages as primary evaluation results by symbols “「 ”,“ ◯ ”and“ Δ ”representing each step. Is done. As shown in FIG. 4B, the evaluation result display field W2 displays a plurality of stages of evaluation results as a primary evaluation result by a line graph.

When it is determined that the evaluation result is input through the input interface 21 for the k _ij evaluation item g _ijk (FIG. 2 / STEP 206... YES), the secondary index k _ij is increased by “1” (FIG. 2). / STEP 208). As a result, the evaluation result can be input through the input interface 21 for the k _ij +1 evaluation item g _{ijk + 1} (see FIG. 2 / STEP 204). 2 Corresponds to “second designation operation” for enabling the input of evaluation results for evaluation items in accordance with the designation order. When it is determined that no evaluation result is input through the input interface 21 for the k _ij evaluation item g _ijk (FIG. 2 / STEP 206... NO), the secondary index k _ij is maintained as it is.

Next, the presence / absence of the first designation operation through the input interface 21 is determined (FIG. 2 / STEP 210). For example, the input operation of the evaluation result through the input interface 21 for all the essential items in the evaluation items g _ijk constituting the j _i evaluation item group (secondary index k _ij exceeds the number of the required items) May be defined as the first designation operation. In addition to the input operation of the evaluation result through the input interface 21 for all of the essential items of the evaluation items g _ijk constituting the j _i evaluation item group, “Next” shown in FIG. 4A and FIG. 4B. An additional input operation such as “tapping button Q2 such as“ ”may be defined as the first designation operation. Instead of determining whether or not the first designated operation has been performed, a determination unrelated to the presence or absence of an operation through the input interface 21 such as whether or not the specified time has elapsed may be executed.

When it is determined that the first designation operation has been performed (FIG. 2 / STEP 210... YES), the primary index j _i is the number of situations constituting the i-th situation group (all j _i corresponding to the i-th situation group _). whether equal endpoint group G number _ij) N _i is determined (Fig. 2 / STEP212). If the determination result is negative (FIG. 2 / STEP 212... NO), the primary index j _i is increased by “1” (FIG. 2 / STEP 214), and then the j _i evaluation item group is the output interface 22. (FIG. 2 / STEP 202). Thus, for example, instead of the one evaluation item group shown in Table 1, another evaluation item group shown in Table 2 is output through the output interface 22 in accordance with the first designation order. Note that at least one of the i-th situation groups may be configured by a single situation.

When the determination result is affirmative, that is, when there is a first designation operation through the input interface 21 for all the j _i evaluation item groups (FIG. 2 / STEP 212... YES), the reference index i is all the situations. It is determined whether or not the number is equal to the number N of groups (“3” in the present embodiment) (FIG. 2 / STEP 216). If the determination result is negative (FIG. 2 / STEP 216... NO), I (i + 1) is set as a new I (i) (FIG. 2 / STEP 218), and then the reference index i is “I (i ) ”, The primary index j _i is set to“ 1 ”, and the secondary index k _ij is set to“ 1 ”(FIG. 2 / STEP 201).

When the determination result is affirmative, that is, when there is a first designation operation through the input interface 21 for all j _i evaluation item groups of all i th situation groups (FIG. 2 / STEP 216... YES), Whether the secondary evaluation result is requested is determined (FIG. 2 / STEP 220). This determination is executed depending on whether or not a predetermined operation has been performed through the input interface 21, for example. When it is determined that there is a request for the secondary evaluation result (FIG. 2 / STEP 220... YES), a request for the secondary evaluation result is transmitted from the client 2 to the server 1 (FIG. 2 / STEP 222 and arrow X1). The request includes a primary evaluation result regarding one or a plurality of evaluation item groups.

The server 1 determines the secondary evaluation result based on the primary evaluation result included in the request (FIG. 2 / STEP 102). For example, the weighted sum Σ _ijk α _ijk e (g _ijk ) of the primary evaluation result e (g _ijk ) ( _numerized score) for the k _ij evaluation item g _ijk is calculated as the secondary evaluation result. In addition, the secondary evaluation result may be derived according to a predetermined table based on the combination of the primary evaluation results e (g _ijk ) of each evaluation item g _ijk . The secondary evaluation result is transmitted from the server 1 to the client 2 (FIG. 2 / STEP 104 and arrow X2).

  Then, in the client 2, the secondary evaluation result is output through the output interface 22 (FIG. 2 / STEP 224). As a result, for example, as shown in FIG. 5, the digitized total score and the corresponding comment are displayed as a secondary evaluation result on the display constituting the output interface 22.

(effect)
According to the driving ability evaluation system having the above-described configuration, each of the plurality of evaluation item groups G _ij corresponding to the i-th situation group has a first designated operation through the input interface 21 and corresponds to the first index j _i . 1 are sequentially output in accordance with the specified order (FIG. 2 / STEP 201 → STEP 202 → STEP 210 → STEP 214 → STEP 202 → STEP 210 → STEP 214 → STEP 202 →... .

  Then, for each of the plurality of evaluation item groups, the evaluation results of the subject's higher brain function and body function are sequentially input according to the first designated order (FIG. 2 / STEP 201 → STEP 202 →... STEP 206 → STEP 214 → STEP 202 → STEP 206 → STEP 214 → STEP 202 → STEP 206 →... (See FIGS. 4A and 4B). Further, in addition to sequentially outputting a plurality of evaluation item groups in accordance with the first designation order, each evaluation item constituting at least one evaluation item group every time there is a second designation operation through the input interface 21. The evaluation results are sequentially input in accordance with the second designation order (see FIG. 2 / STEP 201 →... STEP 204 → STEP 206 → STEP 208 →... STEP 201 →... STEP 204 → STEP 206 → STEP 208 →.

  The “plurality of situations” is a situation where the target person is not actually driving the vehicle 4. Even if the subject is poor or lacking in driving ability for driving the vehicle 4, the driving ability is accurately evaluated, and as a result, the width of the subject is expanded. Further, in a plurality of situations, the “first situation group” consisting of one or a plurality of situations in which the subject person is virtually in contact with the vehicle 4 and the subject person is actually in contact with the stopped vehicle 4. A “second situation group” consisting of one or more situations is included. Not only in a situation where the subject person is virtually in contact with the vehicle 4 in the situation constituting the first situation group, but also in a situation where the subject person is actually in contact with the vehicle 4 in the situation constituting the second situation group Since the higher-order brain function and body function of the subject are evaluated, the accuracy of evaluating the driving ability of the subject can be improved.

  Further, the vehicle 4 of the subject determined based on the primary evaluation result as the evaluation result by the evaluator for each of the evaluation items constituting the plurality of evaluation item groups related to the subject's higher brain function and physical function. The secondary evaluation result as a comprehensive evaluation result regarding the driving ability is output (see FIG. 2 / STEP220... YES → STEP222 → STEP102 → STEP104 → STEP224, FIG. 5).

(Other embodiments of the present invention)
In the above-described embodiment, the driving capability system is configured by the server 1 and the client 2. However, as another embodiment, the driving capability system may be configured by a single device (for example, the client 2).

  In the embodiment, the plurality of situations included the first, second, and third situation groups, but as another embodiment, one of these three situation groups (for example, the first situation group). Or only two (for example, the first and second situation groups) may be included in the plurality of situations.

  The driving ability evaluation system may include a first virtual environment creation device that creates a virtual environment around the subject in one situation or each situation constituting the first situation group. In this case, although the subject is not actually driving and driving the vehicle 4, the environment of the subject in a situation close to the situation is virtually created.

  For example, a subject is seated on a simulated seat of a vehicle seat, a goggle-type virtual reality (VR) device is mounted on the head, and the subject is visually recognized while in the vehicle and outside the vehicle. A simulated operation system constituting a simple operation interface may be operated. The simulation sheet, the VR device, and the simulation operation system constitute a “first virtual environment creation device”. Thereby, the situation which comprises a 1st condition group is diversified, and the improvement of the evaluation precision of a subject's driving ability is aimed at based on the evaluation result of the evaluation item in the said diversified situation by extension.

  The driving ability evaluation system may include a second virtual environment creation device that creates a virtual environment around the vehicle 4 in contact with the subject in one situation or each situation constituting the second situation group. . In this case, the environment of the vehicle 4 in contact with the subject in a situation close to the situation is virtually created although the subject is not actually driving and running the vehicle 4.

  For example, the subject may be actually seated in the driver's seat of the vehicle 4 and a goggle-type VR device may be attached to the head of the subject to visually recognize the subject outside the vehicle. The VR device constitutes a “first virtual environment creation device”. Thereby, the situation which comprises a 2nd situation group is diversified, and the improvement of the evaluation precision of a subject's driving ability is achieved based on the evaluation result of the evaluation item in the said diversified situation by extension.
