Hereinafter, the control device according to the embodiment of the present invention will be described. In the control device according to the embodiment of the present invention, the question presenting unit presents a question to the operator who controls the moving body, and the regulatory unit issues a warning based on the state of the answer to the question by the operator. Notify or regulate the running of moving objects. In addition, the question control unit controls the frequency of presenting questions from the next time onward based on the state of the operator's answer. By doing so, it becomes possible to detect the operator in a state where it is presumed that the operation of the moving body such as dementia is not preferable by answering the question. In addition, since the frequency of presenting questions from the next time onward is controlled based on the state of the operator's answer, it is possible for a healthy operator to reduce the frequency of presenting questions to reduce annoyance. ..

In addition, a calculation means for calculating the correct answer rate based on the answer result to the operator's question is further provided, and the question control unit reduces the frequency of presenting the next and subsequent questions as the correct answer rate increases, and the correct answer rate decreases. Therefore, the frequency of presenting questions from the next time onward may be increased. By doing so, it is possible to control the frequency of question presentation in consideration of the state of the operator's answers so far. In addition, by accumulating the past answer results and calculating the correct answer rate, it is possible to reduce the fluctuation of the presentation frequency due to accidental correct answers, etc., and to make the frequency suitable for the operator's condition.

In addition, when the answer to the operator's question is correct, the question control unit may present the next and subsequent questions less frequently than when the answer is incorrect. By doing so, when the operator answers the question correctly, it is possible to determine that the operator is in a healthy state, reduce the frequency of presenting the question, and reduce the troublesomeness of answering the question. ..

In addition, a measurement unit that measures the time required for the operator to input the answer to the question is further provided, and the question control unit presents the next and subsequent questions as the time required to input the answer to the question becomes longer. The frequency of asking questions may be increased, and the frequency of presenting the next and subsequent questions may be reduced as the time required for inputting the answer to the question becomes shorter. By doing so, even if it is slow and takes a long time to enter the answer instead of the content of the answer, it is presumed that the operator is in an unfavorable state for maneuvering, and it is frequently assumed. You can ask questions. In addition, when the answer is input quickly and for a short time, the frequency of questions can be reduced so that a healthy operator does not feel annoyed.

Further, an acquisition unit for acquiring the age of the operator may be further provided, and the question control unit may not present the question when the age of the operator is less than a predetermined value. By doing so, for example, it is possible to present the question only to the elderly and not to present the question to other persons. Therefore, it is possible to prevent the operator other than the elderly from feeling annoyed.

Further, a transmission means for transmitting the answer result or the correct answer rate to a predetermined contact may be further provided. By doing so, the answer result or the correct answer rate of the operator can be notified to the operator's family and the like, and the family and the like can grasp the signs of the operator's dementia and the like.

In addition, the question control unit may change the number of questions from the next time onward based on the state of the operator's answer. By doing so, if it is presumed that the driver is in an unfavorable state for maneuvering as a result of the driver's answer, increase the number of questions to improve the situation of the driver. It can be grasped accurately.

Further, the control method according to the embodiment of the present invention presents a question to the operator who controls the moving body in the question presenting process, and answers the question by the operator in the regulation process. Warning notification or movement of moving objects is regulated based on. Further, in the question control process, the frequency of presenting questions from the next time onward is controlled based on the state of the answer. By doing so, it becomes possible to detect the operator in a state where it is presumed that the operation of the moving body such as dementia is not preferable by answering the question. In addition, since the frequency of presenting questions from the next time onward is controlled based on the state of the operator's answer, it is possible to reduce the frequency of presenting questions to a healthy operator and reduce the annoyance.

Further, it may be a control program in which the above-mentioned control method is executed by a computer. By doing so, it becomes possible to detect a driver in a state where it is presumed that maneuvering a moving object such as dementia is not preferable by answering a question using a computer. In addition, since the frequency of presenting questions from the next time onward is controlled based on the state of the answer, it is possible to reduce the frequency of presenting questions to a healthy operator and reduce the annoyance.

The control device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 4. The in-vehicle device 1 is mounted on a vehicle as a moving body, for example, and as shown in FIG. 1, the input unit 11, the display unit 13, the vehicle control unit 14, and the communication unit 15 are electrically connected. Then, the in-vehicle device 1 and the communication unit 15 constitute the control device 10 according to the present embodiment. The moving body on which the control device 10 is mounted is not limited to a vehicle, but may be a ship, an aircraft, or the like.

The in-vehicle device 1 includes a driver authentication unit 2, a question control unit 3, an answer result storage unit 4, and an output control unit 5. The in-vehicle device 1 may be configured as, for example, an ECU (Electronic Control Unit), or the control unit of a device such as a car navigation device is a driver authentication unit 2, a question control unit 3, an answer result storage unit 4, and output control. It may be configured to perform the function of the part 5.

The driver authentication unit 2 authenticates the driver of the vehicle. Examples of the authentication method include a display unit 13 displaying options as shown in the upper part of FIG. 2, and a fingerprint authentication method as shown in the lower part of FIG. Alternatively, the password may be input from the input unit 11.

The question control unit 3 creates a question to be presented to the driver (operator) and displays it on the display unit 13. In addition, the question control unit 3 determines whether the answer to the question is correct or incorrect, calculates the correct answer rate, determines and controls the frequency of presenting the question, and the like. The detailed operation will be described later. That is, the question control unit 3 controls the question presentation unit that presents the question to the driver who drives (steers) the vehicle, and the frequency of presenting the question from the next time onward based on the state of the driver's answer. It functions as a question control unit.

The answer result storage unit 4 is composed of, for example, a storage means such as a non-volatile memory or an HDD (Hard Disk Drive), and stores the driver's answer history to the question created by the question control unit 3, the driver's personal information, and the like. accumulate. This response history may be accumulated only for a predetermined period such as the last 6 months. Further, the response result storage unit 4 may be configured by an external database server or the like. When configured as an external database server, information about the authenticated driver is acquired from the database server, for example, via the communication unit 15.

The output control unit 5 displays a warning on the display unit 13 or restricts the vehicle control unit 14 from starting the engine or the like based on the answer result and the correct answer rate determined by the question control unit 3. It outputs a control signal. That is, the output control unit 5 functions as a regulation unit that notifies the warning or regulates the running of the vehicle based on the state of the answer to the question by the driver.

The input unit 11 is composed of a touch panel, a push button, or the like superimposed on the display unit 13, and is used for driver authentication and input of answer to a question shown in FIG. The answer may be input by voice.

A signal indicating that the ignition switch (key switch) or push switch of the vehicle has been operated (turned on) is input to the IGN 12. In this embodiment, the driver authentication by the driver authentication unit 2 is started by inputting the signal from the IGN 12.

The display unit 13 is composed of, for example, a liquid crystal display, an EL (Electro Luminescence) display, or the like, and displays the above-mentioned driver authentication screen, questions, warnings, and the like.

The vehicle control unit 14 is, for example, an ECU that controls the engine of the vehicle, and restricts the start of the engine (prevents it from starting) when a signal for restricting the start is input from the control device 1.

The communication unit 15 is wirelessly connected to the Internet, a public line network, or the like, and under the control of the control device 1, communicates with a predetermined contact set in advance, such as sending an e-mail.

Next, the operation (control method) of the control device 10 having the above-described configuration will be described with reference to the flowchart shown in FIG. The flowchart of FIG. 3 is mainly executed by the in-vehicle device 1. Further, when the in-vehicle device 1 is composed of an ECU or a CPU (Central Processing Unit), by using this flowchart as a computer program, the control method becomes a control program executed by the computer. In step S101 of FIG. 3, the driver authentication unit 2 determines whether or not the IGN 12 is ON, and if it is ON (YES), the process proceeds to step S102, and if it is OFF (NO), this step is performed. Wait at.

Next, in step S102, the driver authentication unit 2 performs driver authentication by the above-mentioned options, fingerprint authentication, etc., and if the authentication is successful, the process proceeds to step S103, and if the authentication fails, the process proceeds to step S115, and the initial authentication is performed. In the case or when the personal information is not set, the process proceeds to step S113 to register the driver.

Next, in step S103, the question control unit 3 reads out the driver's personal information and the answer history information authenticated in step S102 from the answer result storage unit 4, and proceeds to step S104. Examples of personal information include name, date of birth, address, and contact e-mail address. The answer history includes, for example, the number of questions, the number of correct answers, and the date of the previous question presentation. The contact information includes the contact information of the driver's family and relatives, but may be a family hospital, government office, police station, or the like.

Next, in step S104, the question control unit 3 determines whether or not to display the question, proceeds to step S105 if it is displayed, and ends if it is not displayed. The detailed operation of this step will be described later.

Next, in step S105, the question control unit 3 displays (presents) the question (first question) on the display unit 13, prompts the input of the answer, and proceeds to step S106. Questions include, for example, those created from personal information (date of birth, age, zodiac or address prefecture name, city, town, village name, etc.) and those created from information not related to a specific individual (today's date, day of the week, current location). Prefecture name, city, town, village name, etc.). Alternatively, it may be a simple puzzle or a simple calculation problem. In addition, it is desirable that the content of the question be such that a person in a healthy state can easily answer it.

Next, in step S106, the question control unit 3 processes the answer result of the question displayed in step S105, and proceeds to step S107. As the processing contents of the answer result, for example, if the answer to the question is a correct answer, the number of questions is counted up and the number of correct answers is counted up, and if the answer to the question is an incorrect answer, only the number of questions is counted up. do.

Next, in step S107, the question control unit 3 displays (presents) the question (second question) on the display unit 13, prompts the input of the answer, and proceeds to step S108. It is desirable that the content of the question is different from that of step S105.

Next, in step S108, the question control unit 3 processes the answer result of the question displayed in step S107, and proceeds to step S109. In this embodiment, the number of questions is set to 2, but when there are 3 or more questions, the steps of displaying / answering the questions and processing the answer result are repeated for the number of questions. If there is only one question, steps S107 and S108 are omitted.

Next, in step S109, the question control unit 3 determines whether or not the driver has correctly answered all the questions displayed in steps S105 and S107, and if all the questions are correct (yes), the process ends. If all the questions are not correct (NO), the process proceeds to step S110. In this step, for example, when the correct answer rate for the last 6 months is less than a predetermined value (for example, less than 98%), the process may proceed to step S110.

Next, in step S110, as a result of the determination in step S109, all the questions were not correct, so for example, "I did not answer the vehicle start question correctly. The correct answer rate for 6 months is (number of correct answers) / ( The number of questions). ” The correct answer rate to be included in the email may be expressed as a percentage, or may be the correct answer rate this time. Alternatively, it may be the answer result (question content and its answer).

Next, in step S111, the question control unit 3 determines whether or not the driver has answered all the questions incorrectly in the questions displayed in steps S105 and S107, and if all the questions are incorrect (yes), The process proceeds to step S112, and if all the questions are not incorrect (NO), the process ends. In this step, for example, when the correct answer rate for the last 6 months is less than a predetermined value (for example, less than 80%), the process may proceed to step S112.

Next, in step S112 and in step S111, all the questions were incorrect, so the question control unit 3 displays a message on the display unit 13 such as "I don't feel well today. Please refrain from driving." And finish. A control signal may be output to the vehicle control unit 14 to limit the start of the engine together with or instead of displaying the message.

On the other hand, in step S113, since the driver authentication unit 2 has determined in step S102 that the initial authentication or personal information has not been set, it is determined whether or not to set the personal information, and if so (YES). If), the process proceeds to step S114, and if not (NO), the process proceeds to step S105. Whether or not to set the question may be selected by displaying the display unit 13 to that effect, for example.

Next, in step S114, the driver authentication unit 2 prompts the input of personal information to register the driver, and proceeds to step S105. Step S105 and subsequent steps are the same as those described above. Questions when this step is executed may be created based on the personal information and the like entered in this step. In addition, the question when personal information is not set may be created from information not related to a specific individual.

Further, in step S115, since the authentication failed in step S102, the driver authentication unit 2 disables the start of the vehicle engine and outputs a control signal to the vehicle control unit 14. Although it is not possible to start the device in this embodiment, this step may be omitted if the authentication fails due to a problem on the device side such as fingerprint recognition accuracy.

Next, the question display determination in step S104 described above will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 4 is executed by the question control unit 3.

First, in step S201, for example, it is determined whether or not the driver's age is 70 years or older based on the personal information read by the driver authentication unit 2, and if it is 70 years or older (YES), the step Proceeding to S202, if the person is under 70 years old (NO), the question control unit 3 determines that the question is not displayed. That is, the driver authentication unit 2 functions as an acquisition unit for acquiring the age of the driver. In addition, the question control unit 3 does not present the question when the driver's age is less than a predetermined age.

The age to be determined in this step is not limited to 70 years, and an age at which an elderly person can be determined may be set. In this embodiment, this step is provided for the elderly, but this step may be omitted if it is performed regardless of age.

Next, in step S202, the cumulative correct answer rate for the last 6 months is calculated based on the information of the answer history (number of correct answers, number of questions) read by the driver authentication unit 2, and the determination is made as follows. If the correct answer rate is 98% or more, the process proceeds to step S203, if the correct answer rate is 90% or more and less than 98%, the process proceeds to step S204, and if the correct answer rate is 80% or more and less than 90%, the process proceeds to step S205. If the rate is less than 80%, it is determined that the question is displayed. That is, the question control unit 3 functions as a calculation means for calculating the correct answer rate based on the answer result to the question.

As explained in step S105, the question in this embodiment is a correct answer if it is in a healthy state. Therefore, if the correct answer rate is less than 80%, there is a problem in the health state such as dementia. It is estimated that the question is always displayed. Also, since there is no data in the initial state, the question is displayed.

Next, in step S203, it is determined whether or not 14 days or more have passed since the previous question was presented, and if it has passed (YES), it is determined that the question is displayed, and if it has not passed (YES). If NO), it is determined that the question is not displayed. In this step, the correct answer rate is 98% or more, which is a fairly high probability, so it is estimated that the patient is in a healthy state and the frequency of question presentation is set longer.

Next, in step S204, it is determined whether or not 7 days or more have passed since the previous question was presented, and if it has passed (YES), it is determined that the question is displayed, and if it has not passed (YES). If NO), it is determined that the question is not displayed. In this step, the correct answer rate is 90% or more and less than 98%, which is a high probability. ing.

Next, in step S205, it is determined whether or not one day or more has passed since the previous question was presented, and if it has passed (YES), it is determined that the question is displayed, and if it has not passed (YES). If NO), it is determined that the question is not displayed. In this step, since the correct answer rate is 80% or more and less than 90%, it is presumed that a health problem is suspected, and the frequency of question presentation is set to be high.

The value of the correct answer rate determined in step S202 is an example and may be changed as appropriate. In this embodiment, as described above, the question is the one that answers correctly if it is in a healthy state, so the standard of the correct answer rate is set high.

In addition, the reason why the correct answer rate for the last 6 months is set in step S202 of FIG. 4 is to limit the number of questions because it is difficult for the correct answer rate to change even if the number of incorrect answers continues to be too large. be. In addition, the latest trends can be known by setting the latest period. Of course, the predetermined period of 6 months may be changed, and the number of questions (the latest 100 questions, etc.) may be limited to the period.

That is, according to the flowchart of FIG. 4, the question control unit 3 reduces the frequency of presenting questions from the next time onward as the correct answer rate of the driver increases, and asks questions from the next time onward as the correct answer rate decreases. The frequency of presentation is high.

According to this embodiment, in the control device 10, the question control unit 3 causes the driver who drives the vehicle to present the question to the display unit 13, and the output control unit 5 answers the question by the driver. To regulate the notification of warnings or the start of the engine of the vehicle based on. In addition, the question control unit 3 controls the frequency of presenting questions from the next time onward based on the state of the driver's answer. By doing so, it becomes possible to detect a driver in a state where it is presumed that driving a vehicle is not preferable, such as dementia, by answering the question. In addition, since the frequency of presenting questions from the next time onward is controlled based on the state of the driver's answer, it is possible to reduce the frequency of presenting questions to a healthy driver and reduce the annoyance.

In addition, the question control unit 3 calculates the correct answer rate based on the answer result to the driver's question, reduces the frequency of presenting questions from the next time onward as the correct answer rate increases, and from the next time onward as the correct answer rate decreases. Frequently ask questions to. By doing so, it is possible to control the frequency of presenting questions in consideration of the state of the driver's answers so far. In addition, there is less variation in the presentation frequency due to accidental correct answers.

Further, the driver authentication unit 2 acquires the driver's age, and the question control unit 3 does not present the question when the driver's age is less than 70 years old. By doing so, it is possible to present the question only to the elderly and not to present the question to other persons. Therefore, it is possible to prevent drivers other than the elderly from feeling annoyed.

Further, the control device 10 includes a communication unit 15 that transmits a correct answer rate to a contact such as a guardian when the question is incorrect. By doing so, the driver's answer result or the correct answer rate can be notified to the driver's family and the like, and the family and the like can grasp the signs of the driver's dementia and the like.

Next, the control device 10 according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The same parts as those in the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the method of determining the question display in step S104 is different. In this embodiment, a counter is provided in the question control unit 3. This counter can count up and down between numerical values of 0 to 3. FIG. 5 shows a flowchart of the operation of the control device 1 according to the present embodiment.

Steps S101 to S115 are the same as those in the first embodiment. In step S301, which proceeds to the case where step S109 is not a correct answer for all questions (NO), the counter is counted down (count value -1) and the process proceeds to step S110.

On the other hand, in step S302 which proceeds to the case where all the questions are correctly answered in step S109 (when YES), the counter is counted up (count value + 1) and the process ends.

FIG. 6 is a flowchart of the question display determination according to the present embodiment. In FIG. 6, steps S201 and S203 to S205 are the same as in the first embodiment. In FIG. 6, in step S401 to be executed instead of step S202, the determination is made based on the count value of the counter described above. That is, when the count value is "3", the process proceeds to step S203, when the count value is "2", the process proceeds to step S204, when the count value is "1", the process proceeds to step S205, and the count value is "0". In the case of, it is judged that the question is displayed.

That is, in this embodiment, the question display frequency is changed only based on the driver's previous answer result. This means that as the count value increases, the frequency of displaying the next and subsequent questions decreases, and as the count value decreases, the frequency of displaying the next and subsequent questions increases. That is, when the answer to the driver's question is correct, the question control unit 3 reduces the frequency of presenting the question from the next time onward to the case where the answer is incorrect.

As is clear from the flowchart of FIG. 6, this counter does not become a value larger than "3" even if all the correct answers are repeated, and does not become less than "0" even if the wrong answer is repeated.

Further, the increase / decrease of the count value of the counter does not have to be one by one. For example, when two questions are presented as shown in FIG. 5, it may be changed according to the number of questions, such as -1 for one wrong answer and -2 for two wrong answers.

According to this embodiment, when the answer to the driver's question is correct, the question control unit 3 reduces the frequency of presenting the question from the next time onward to the case where the answer is incorrect. By doing so, if the answer is correct, it is possible to determine that the driver is in a healthy state, reduce the frequency of presenting questions, and reduce the annoyance.

Next, the control device according to the third embodiment of the present invention will be described with reference to FIG. The same parts as those of the first and second embodiments described above are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the method of determining the question display in step S104 is different. In this embodiment, the question control unit 3 measures the time (answer time) required from displaying the question on the display unit 13 by a timer or the like until the answer is input. The response time may be the time until the answer is started to be input, or the time until the answer input is completed.

FIG. 7 is a flowchart of the question display determination according to the present embodiment. In FIG. 7, steps S201 and S203 to S205 are the same as in the first embodiment. In FIG. 7, in step S501 to be executed instead of step S202, the response time measured by the timer or the like described above is used for determination. That is, the question control unit 3 functions as a measurement unit that measures the time required for the driver to input an answer to the question. In step S501, if the response time is less than 10 seconds, the process proceeds to step S203, if the response time is 10 seconds or more and less than 20 seconds, the process proceeds to step S204, and if the response time is 20 seconds or more and less than 30 seconds, the process proceeds to step S205. If the answer time is 30 seconds or more, it is judged that the question is displayed.

That is, in this embodiment, the question display frequency is changed based only on the answer time of the driver. That is, the question control unit 3 increases the frequency of displaying the question as the time required for inputting the driver's answer becomes longer, and decreases the frequency of displaying the question as the time becomes shorter.

The determination reference time of the answer time shown in FIG. 7 is an example, and may be appropriately changed depending on the method of inputting the answer to the question (choice, numerical input, voice input, etc.). Further, this answering time may be the average answering time of two questions when the number of questions is two as shown in FIG. 3, or may be determined by the answering time of either one. Further, this response time may also be accumulated in the response result storage unit 4 as the information of the response history, and the determination may be made based on the average response time including the past history.

Further, this embodiment may be combined with the first and second embodiments. That is, the question display frequency may be changed based on both the correct answer rate and the count value and the answer time.

According to this embodiment, the question control unit 3 measures the time required for the driver to input the answer to the question, and asks the next and subsequent questions as the time required for inputting the answer to the question becomes longer. The frequency of presentation is increased, and the frequency of presenting the next and subsequent questions is reduced as the time required to input the answer to the question becomes shorter. By doing so, even if it is late to enter the answer instead of the content of the answer, it is presumed that the driver is in an unfavorable state for driving, and questions are frequently asked. Can be done. In addition, when the answer is input quickly and for a short time, the frequency of questions can be reduced so that a healthy driver does not feel annoyed.

In each of the above-described embodiments, the number of questions was fixed, but for example, the number of questions may be changed. For example, the number of questions from the next time onward increases as the correct answer rate and count value decrease or the answer time increases, and the number of questions from the next time onward increases as the correct answer rate and count value increase or the answer time decreases. You may try to do it. That is, the number of questions from the next time onward may be changed based on the state of the driver's answer.

Further, in each of the above-described embodiments, it has been described that it is mainly performed for a driver who may have dementia, but it can also be performed for a driver who is presumed to be drunk or overworked, for example. Is. Even in the case of drinking alcohol (drunkenness, etc.) or overwork (drowsiness, loss of concentration, etc.), the answer to a simple question may be incorrect or it may take time to answer, so the present invention is applied. It is possible.

Further, in each of the above-described embodiments, the device mounted on the vehicle has been described, but the device can be applied to a device that can be detached from the vehicle, such as a smartphone, as long as a warning is displayed on the display unit. In this case, the driver's authentication may be started by attaching it to a cradle or the like, or by recognizing that the driver is in the parking lot from the current position.
