Description

The present invention relates to a technique for evaluating the driving ability of a subject's vehicle.

A technique for analyzing and evaluating the driving skills of subjects including persons with higher brain dysfunction has been proposed (see, for example, Patent Document 1). An image for driving simulation and an image are generated according to the operation of the simulated operation device, and after selecting the driving experience scene and the driving course, the physical function of the subject and the reaction to the displayed image are measured, and the driving operation ability and the driving operation ability and the reaction to the displayed image are measured. A technique for examining higher brain dysfunction has been proposed (see, for example, Patent Document 2). The driving path is displayed on the front display of the simulated driver's seat, and in addition to the amount of sweating and skin potential of the driver's palm at this time, the amount of depression of the brake pedal and accelerator pedal is detected to drive the driver. A technique for evaluating behavior has been proposed (see, for example, Patent Document 3). Either the primary image with the image gaze area or the secondary image with different information in the discontinuation area is selectively displayed on the display, and the activity of the subject's brain function is evaluated based on the response result of the subject at this time. (See, for example, Patent Document 4). When the maneuvering influence force that may affect the vehicle maneuvering is equal to or higher than the set value, a technique for reducing the degree of danger when the vehicle is running has been proposed based on medical information (see, for example, Patent Document 5).

It is provided with an input interface for allowing the evaluator to input the evaluation results for each evaluation item constituting each of the plurality of evaluation item groups output by the output interface.
The plurality of situations include a first situation group consisting of one or a plurality of situations in which the target person is virtually in contact with the vehicle, and the target person is actually in contact with the vehicle in a stopped state. a second status group consisting of one or more conditions that are characterized by that contains.

According to the driving ability evaluation system of the present invention, each of the plurality of evaluation item groups corresponding to each of the plurality of situations is sequentially output according to the first designated order. The "first designated order" defines 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 the output is performed before any one or a plurality of evaluation items g ₁₁ , g ₁₂ , ... Constituting the evaluation item group G _1. Then, for each of the plurality of evaluation item groups, the evaluation results of the higher brain function and the physical function of the subject are sequentially input according to the first designated order.

"Input" includes contact input such as manual input, as well as non-contact input such as voice input or line-of-sight detection. “Output” means that the user outputs information in a form that can be recognized through the five senses such as sight and hearing. The "evaluation item group" consists of one or more 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 partially matched. good.

The "plurality of situations" is a situation in which the subject is not actually driving the vehicle. Even if the subject has poor or lacking driving ability to drive the vehicle, the driving ability is accurately evaluated, and as a result, the width of such a subject can be expanded. In addition, the plurality of situations include a first situation group and a second situation group. The "first situation group" consists of one or more situations in which the subject is virtually in contact with the vehicle, for example, realized by a drive simulator. The "second situation group" consists of one or more situations in which the subject is in contact with the vehicle, such as a situation in which the subject can actually get on and off the stopped vehicle or a situation in which the subject is in the vehicle. The target is not only in the situation where the subject is virtually in contact with the vehicle in the situation constituting the first situation group, but also in the scene in which the subject is actually in contact with the vehicle in the situation constituting the second situation group. Since the higher brain function and physical function of the subject are evaluated, the accuracy of evaluation of the driving ability of the subject can be improved.

(How to use the driving ability evaluation system)
According to the driving ability evaluation system, for example, each of the higher brain function and the physical function of the subject is evaluated according to the order shown in FIG. Here, "i" is a "reference index" for identifying each of the i-situation groups. "I (i)" is an index for determining the order of each of the i-situation groups. "J _i" serves to identify the endpoint group corresponding to the situation or which constitute the i-th status group, a "primary index" for defining the "first specified order." “K _ij ” is _{a “secondary index” for identifying each evaluation item constituting the j i} evaluation item group and determining the “second designated order”.

Corresponding to the third evaluation evaluation for each evaluation item g _3Jk item group G ₃ → first status group (i = I (2) = 1) corresponding to the third situation group (i = I (1) = 3) 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 Therefore, each of the higher brain function and the physical 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 ( It may be changed in any order such as 1) = 1 → I (2) = 3 → I (3) = 2.

Further, for the j _i endpoint group G _ij constituting the i-th status group, each of higher brain function and physical function in a subject is evaluated according to the "first specified order" that G _i1 → G _i2 → ‥ (See Fig. 3 / gray arrow). Furthermore, for the k _ij evaluation item g _{ijk that constitutes the j i} evaluation item group G _ij , the "second designated order" of g _i11 → g _i12 → ‥ g _i21 → g _i22 → ‥ g _iNi1 → g _{iNi2 → ‥} The higher brain function and physical function of the subject are evaluated according to the above (see Fig. 3 / white arrow).

(Action)
The operation or function of the driving ability system having the above configuration will be described. The arithmetic processing in the server 1 is executed by the arithmetic processing unit 14, and the arithmetic processing in the client 2 is executed by the arithmetic processing element 24.

When the predetermined application software (application) for executing the driving ability evaluation is started in the client 2 through the input interface 21, the reference index i for identifying each of the i-situation groups is "I (i). _{(I (i) = 1, 2, 3), and the primary index j i} (j _i = 1, 2, 3) for identifying the situations constituting the i-situation group or the corresponding evaluation item group. , ...) is set to "1", and the _{secondary index k ij} (ki _ij = 1, 2, ...) For identifying each evaluation item constituting _{the j i evaluation item group is set to "1".} It is set (Fig. 2 / STEP201). The primary index j _i is the index for determining the "first specified order", the secondary index k _ij is the index to determine the "second specified order."

The "first situation group" is composed of one or more situations in which the subject is virtually in contact with the vehicle 4. The "second situation group" is composed of one or more situations in which the subject is actually in contact with the stopped vehicle 4. The "third situation group" is composed of one or more situations in which the subject does not virtually or actually touch the vehicle 4. Each of the first, second, and third situation groups is a situation in which the person whose driving ability is evaluated does not actually drive the vehicle 4.

Automatically in response to this, or, in response to a trigger operation through the input interface 21, the j _i endpoint group is output through the output interface 22 (FIG. 2 / STEP 202). The "evaluation item group" consists of one or more evaluation items for evaluating each of the higher brain function and the physical function of the subject. As a result, for example, images as shown in FIGS. 4A and 4B are output through the output interface 22. In the image of FIG. 4A, the display column W0 of the situation that "the subject confirms the front, side, and diagonally rear in the vehicle", "side mirror adjustment", "room mirror adjustment", "power window opening / closing", etc. The evaluation item display column W1 and the evaluation result display column W2 are included. In the image of FIG. 4B, the display column W0 of the situation that "the target person confirms the four corners of the vehicle inside and outside the vehicle", the evaluation item display column W1 such as "confirmation of the four corners of the vehicle (inside the vehicle)", and the evaluation result display. Columns W2 and are included. The evaluation items in the evaluation item display column W1 may be arranged in a certain direction according to the second designated order, and the arranged order may be different from the second designated order (FIGS. 4A and FIG. See 4B).

Each of Tables 1 to 7 shows a group of evaluation items corresponding to one situation and a plurality of examples of evaluation viewpoints of each evaluation item.

Each of the plurality of situations exemplified in each of Tables 1 to 7 may constitute a second situation group, but when a simulator that reproduces the driver's seat of the vehicle 4 is used, for example, the plurality of situations. 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, it is possible to input evaluation result through an input interface 21 (FIG. 2 / STEP 204) .. That is, as the second order specified at this stage, for the evaluation items after order than the k _ij endpoint g _ijk In a j _i evaluation item group, the input of the evaluation result through the input interface 21 is not allowed.

Further, for the _kij evaluation item g _ijk, it is determined whether or not the evaluation result is input through the input interface 21 (FIG. 2 / STEP206). For example, in the evaluation result display column W2 of FIGS. 4A and 4B, the evaluation results of a plurality of stages (in the present embodiment, the evaluation results of the three stages represented by "◎", "○" and "Δ") correspond to the corresponding evaluation viewpoint. Is input to the client 2 by the evaluator based on. The evaluation result may be input by touch operation or keyboard operation of the touch panel constituting the input interface 21, or the evaluation result may be input by the selection operation from the pull-down menu Q1 displayed in the evaluation result display field. ..

The evaluation result input through the input interface 21 is output as the primary evaluation result through the output interface 22. As a result, as shown in FIG. 4A, for example, the evaluation results of a plurality of stages are displayed in the evaluation result display column W2 as the primary evaluation results by the symbols "◎", "○" and "Δ" indicating each stage. Will be done. As shown in FIG. 4B, the evaluation results of a plurality of stages are displayed as the primary evaluation results by a line graph in the evaluation result display column W2.

When it is determined that the evaluation result has been input through the input interface 21 for the k _ij evaluation item g _{ijk (FIG. 2 / STEP206 ... YES), the secondary index k ij} is increased by "1" (FIG. 2). / STEP208). Thus, for the k _ij +1 endpoint g _{ijk + 1,} since it is possible to input evaluation result through an input interface 21 (see FIG. 2 / STEP 204), the input of the evaluation result through an input interface 21, the 2 Corresponds to the "second designation operation" for enabling input of evaluation results for evaluation items in the designated order. When it is determined that the evaluation result has not been input through the input interface 21 for the k _ij evaluation item g _{ijk (FIG. 2 / STEP206 ... NO), the secondary index k ij} is maintained at the same value.

Next, the presence or absence of the first designated operation through the input interface 21 is determined (FIG. 2 / STEP210). For example, the input operation of the evaluation result through the input interface 21 for all the required items among the evaluation items g _{ijk constituting the j i evaluation item group (the secondary index k ij} exceeds the number of the required items). May be defined as the first designated operation. Further, _{for all of the required items among the evaluation items g ijk constituting the j i} evaluation item group, in addition to the input operation of the evaluation results through the input interface 21, "Next" shown in FIGS. 4A and 4B. An additional input operation such as tapping the button Q2 such as "" may be defined as the first designated operation. Instead of determining the presence / absence of the first designated operation, a determination irrelevant to the presence / absence of the operation through the input interface 21, such as whether or not the designated time has elapsed, may be executed.

When it is determined that the first designated operation has been performed (Fig. 2 / STEP210 ... YES), _{the number of situations in which the primary index j i} constitutes the i-situation group (all the j _{i corresponding to the i-situation group).} whether equal endpoint group G number _ij) N _i is determined (Fig. 2 / STEP212). If the judgment result is negative (FIG. 2 / STEP212 ... NO), the primary index j _i is increased by "1" (FIG. 2 / STEP214), and then the j _i evaluation item group is output interface 22. Is output through (Fig. 2 / STEP202). As a result, for example, in accordance with the first designated order, instead of one evaluation item group shown in Table 1, another evaluation item group shown in Table 2 is output through the output interface 22. It should be noted that at least one situation group in the i-situation group may be composed of a single situation.

When the judgment result is affirmative, that is, when _{the first designated operation is performed through the input interface 21 for all the j i} evaluation item groups (FIG. 2 / STEP212 ... YES), the reference index i is all situations. Whether or not it is equal to the number N of the group (“3” in this embodiment) is determined (FIG. 2 / STEP216). If the determination result is negative (FIG. 2 / STEP216 ... NO), I (i + 1) is set as the new I (i) (FIG. 2 / STEP218), and 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 / STEP201).

When the judgment result is affirmative, that is, when the first designation operation is performed through the input interface 21 for _{all the j i evaluation item groups of all the i situation groups (FIG. 2 / STEP216 ... YES).} Whether or not a secondary evaluation result is requested is determined (Fig. 2 / STEP220). The determination is executed, for example, depending on whether or not a predetermined operation has been performed through the input interface 21. When it is determined that there is a request for the secondary evaluation result (FIG. 2 / STEP220 ... YES), the request for the secondary evaluation result is transmitted from the client 2 to the server 1 (FIG. 2 / STEP222 and arrow X1). The request includes primary assessment results for one or more endpoint groups.

The server 1 determines the secondary evaluation result based on the primary evaluation result included in the request (FIG. 2 / STEP102). For example, the _{weighted sum Σ ijk} α _ijk e (g _ijk ) of the primary evaluation result e (g _ijk ) (quantified 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 / STEP104 and arrow X2).

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

(effect)
According to the driving ability evaluation system having the above configuration, each of the plurality of evaluation item groups G _ij corresponding to the i-situation group has a first designated operation through the input interface 21, and the first is corresponding to the _{primary index j i.} 1 Output sequentially according to the specified order (FIG. 2 / STEP201 → STEP202 → ‥ STEP210 → ‥ STEP214 → STEP202 → ‥ STEP210 → ‥ STEP214 → STEP202 → ‥, FIG. 3 / gray arrow, see FIGS. 4A and 4B) ..

Then, for each of the plurality of evaluation item groups, the evaluation results of the higher brain function and the physical function of the subject are sequentially input according to the first designated order (FIG. 2 / STEP201 → STEP202 → ... STEP206 →. STEP214 → STEP202 → STEP206 → STEP214 → STEP202 → STEP206 →, see FIGS. 4A and 4B). Further, in addition to the plurality of evaluation item groups being sequentially output according to the first designated order, each evaluation item constituting at least one evaluation item group each time there is a second designated operation through the input interface 21. The evaluation results are sequentially input according to the second designated order (see FIG. 2 / STEP201 → ‥ STEP204 → STEP206 → STEP208 → ‥ STEP201 → ‥ STEP204 → STEP206 → STEP208 → ‥, FIG. 3 / white arrow).

The "plurality of situations" is a situation in which the subject is not actually driving the vehicle 4. Even if the subject has poor or lacking driving ability to drive the vehicle 4, the driving ability is accurately evaluated, and as a result, the width of such a subject can be expanded. Further, in a plurality of situations, a "first situation group" consisting of one or a plurality of situations in which the target person is virtually in contact with the vehicle 4 and the target person actually contact the vehicle 4 in a stopped state. A "second situation group" consisting of one or more situations is included. Not only in the scene where the subject is virtually in contact with the vehicle 4 in the situation constituting the first situation group, but also in the scene in which the subject is actually in contact with the vehicle 4 in the situation constituting the second situation group. Since the higher brain function and physical function of the subject are evaluated, the accuracy of evaluation of the subject's driving ability can be improved.

Further, the subject's vehicle 4 is 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 higher brain function and the physical function of the subject. The secondary evaluation result as a comprehensive evaluation result regarding the driving ability of the above is output (see FIG. 2 / STEP220: YES → STEP222 → STEP102 → STEP104 → STEP224, FIG. 5).

(Other Embodiments of the present invention)
In the above embodiment, the driving ability system is composed of the server 1 and the client 2, but as another embodiment, the driving ability system may be composed of 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). Only or only two (eg, 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 target person in one situation or each situation constituting the first situation group. In this case, the environment of the target person is virtually created in a situation close to the situation even though the target person is not actually driving and driving the vehicle 4.

For example, a subject is seated on a simulated seat of a vehicle seat, and a goggle-type virtual reality (VR) device is attached to the head of the subject to visually recognize the inside and outside of the vehicle while simulating the subject. The simulated operation system that constitutes the various operation interfaces may be operated. The simulation sheet, the VR device, and the simulation operation system constitute the "first virtual environment creation device". As a result, the situations constituting the first situation group are diversified, and the evaluation accuracy of the driving ability of the subject is improved based on the evaluation results of the evaluation items in the diversified situations.

The driving ability evaluation system may be provided with 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 target person in a situation close to the situation is virtually created even though the target person is not actually driving and driving 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 so that the subject can visually recognize the state outside the vehicle.
