<Overview of Embodiment>
An outline of the embodiment will be described with reference to FIG.
FIG. 1 is a schematic view for explaining an outline of the information processing apparatus 1 according to the embodiment. In the example shown in FIG. 1, the information processing device 1 is mounted on a vehicle V driven by the driver D. The vehicle V includes an in-vehicle monitor 2, an in-vehicle sensor 3, a communication device 4, and a driving support system 5 as well as the information processing device 1.

  The in-vehicle monitor 2 is a display device provided with a touch panel, and is a user interface for the information processing apparatus 1 to present information to the driver D and to acquire information from the driver D. The in-vehicle sensor 3 is a device for monitoring the driver D in a state of sitting on the driver's seat of the vehicle V. The in-vehicle sensor 3 is realized using, for example, a known visible light camera or an infrared camera. The communication device 4 is a communication interface for the vehicle V to communicate with an external device of the vehicle V. The communication device 4 is implemented using a known communication module, such as a mobile phone communication module.

  In recent years, a driving support system for vehicles such as cars, buses, trucks and the like has been rapidly developed, and a vehicle V according to the embodiment is also equipped with such a driving support system 5. The driving support system 5 mounted on the vehicle V includes, for example, a blind spot monitoring system for detecting other vehicles, objects, people, etc. present in the blind spot of the driver D who got on the vehicle V, an engine and steering of the vehicle V, and a brake. A cruise control system or the like that causes the vehicle V to travel automatically by control is included.

  The driving support system 5 is a known technology, and therefore detailed description will be omitted, but the vehicle V is not shown various sensors and power mechanisms (visible light camera, millimeter wave radar, infrared camera, etc.) used for the driving support system 5. An actuator for automatic steering, an actuator for automatic braking) and a controller for controlling these are provided.

  The information processing apparatus 1 according to the embodiment asks the driver D about the health condition via the in-vehicle monitor 2 before the driver D who gets into the vehicle V starts driving the vehicle V. The information processing device 1 changes the setting of the driving support system 5 included in the vehicle V based on the contents of the answer received from the driver D via the in-vehicle monitor 2.

  For example, in the case where the driver D suspects that the driver D has a narrow vision, the information processing apparatus 1 compares the driver D's field of view with a narrow area, ie, an average healthy person. Then, the setting of the driving support system 5 is changed so as to strengthen the blind spot monitoring system in the area where the blind spot of the driver D is widening.

  As another example, in the case where the driver D is suspected to have dementia due to the contents of the driver D's reply, the information processing device 1 prohibits the driver D from driving the vehicle V and communicates This is notified to a predetermined contact via the device 4. In this case, the information processing apparatus 1 causes the driver D to forget the purpose of driving by a method such as prolonging the question. The information processing apparatus 1 also plays a role of earning time until the driver D is discovered as a relative or the like. When the degree of symptoms of the driver D is mild and the driving is permitted, the information processing apparatus 1 changes the settings of the car navigation system and the cruise control system to start monitoring of the traveling locus, or the vehicles around. In order to make the presence of V stand out, the traveling speed should not exceed a certain level.

  As described above, the information processing apparatus 1 changes the setting of the driving support system 5 provided in the vehicle based on the driver's D answers to the plurality of questions regarding the health condition. Thereby, the information processing apparatus 1 according to the embodiment can provide the driving assistance technology according to the inquiry result of the driver.

<Functional Configuration of Information Processing Device 1>
FIG. 2 is a diagram schematically showing a functional configuration of the information processing apparatus 1 according to the embodiment. The information processing apparatus 1 includes a storage unit 10 and a control unit 11. Further, the information processing device 1 can exchange information with the in-vehicle monitor 2, the in-vehicle sensor 3, the communication device 4, and the driving support system 5.

  The storage unit 10 includes a non-volatile storage device such as a Hard Disc Drive (HDD) or a Solid State Drive (SSD), and a temporary storage unit such as a Dynamic Random Access Memory (DRAM). The non-volatile storage device functions as a storage unit for various programs and databases for realizing the information processing device 1 according to the embodiment. The temporary storage unit functions as a working memory of the control unit 11.

  The control unit 11 is a processor such as an ECU (Electronic Control Unit) of the vehicle V. Control unit 11 executes the program stored in storage unit 10 to obtain personal information acquisition unit 110, question selection unit 111, answer acceptance unit 112, support system change unit 113, notification unit 114, operation availability determination unit The function 115 functions as the start prohibition unit 116 and the support information acquisition unit 117.

  The support information acquisition unit 117 acquires, from the driving support system 5, log information of the driving support system 5 and information including an output of a sensor that the driving support system 5 uses to support the vehicle V. The support information acquisition unit 117 stores and accumulates the information acquired from the driving support system 5 in the storage unit 10.

  The personal information acquisition unit 110 acquires personal information of the driver D of the vehicle V before the start of driving of the vehicle V. The personal information acquisition unit 110 may acquire, for example, the name input in a self-report form from the driver D, or may be known biometric authentication for acquiring and authenticating biometric information such as a fingerprint, voiceprint, or iris of the driver D. Technology may also be used to identify personal information. Alternatively, the personal information acquisition unit 110 may read the driver's license presented to the driver D to acquire personal information of the driver D.

  The storage unit 10 stores the driver of the vehicle V in association with the driver ID (Identification) uniquely assigned to the driver. The personal information acquisition unit 110 identifies the driver ID of the driver D from the personal information of the driver D acquired from the driver D.

  FIG. 3 is a view schematically showing a data structure of a driver database stored in the storage unit 10 according to the embodiment. As shown in FIG. 3, the driver database stores information related to the driver D specified by the driver ID in association with the driver ID. Here, "information related to the driver D" is information including information used by the information processing apparatus 1 to determine the driver's D health state, and information indicating the emergency contact address of the driver D. .

  The specific example of the information related to the driver D is, as shown in FIG. 3, a history of the driver D's past illness, the driver D's age, the driver D's driving history, the driver D's driving frequency, the destination history, the driving time It is information such as a band, one continuous operation time, and an e-mail address as an emergency contact point. The driver database is stored in the storage unit 10. FIG. 3 shows information on the driver D whose driver ID is 00001. The driver D with a driver ID of 00001 has a left side visual field stenosis as a history of diseases, an age of 72, a driving history of 46 years, and a driving frequency of once a month.

  Based on the personal information acquired by the personal information acquiring unit 110, the question selecting unit 111 selects the question to be performed on the driver D from among the plurality of questions relating to the health condition prepared in advance. The question selecting unit 111 displays the selected question on the in-vehicle monitor 2.

  The storage unit 10 stores a question database in which various pre-existing diseases and questions corresponding to the pre-existing diseases are associated. When the personal information includes a medical condition of the driver D, the question selection unit 111 selects a question based on the medical condition. Thereby, the question selecting unit 111 can select the question suitable for each driver D.

  The storage unit 10 also stores general questions for the driver D who does not have a past illness. If the driver D does not have a pre-existing condition, the question selecting unit 111 reads general questions such as sleeping time and physical condition from the question database in consideration of the age of the driver D. As described above, the question selecting unit 111 obtains the question to be displayed on the in-vehicle monitor 2 by referring to the question database based on the personal information acquired by the personal information acquiring unit 110.

  FIG. 4 is a diagram schematically showing a data structure of a question database stored in the storage unit 10 according to the embodiment. FIG. 4 shows an example of questions to be presented to the driver D who has a history of “left side view narrowing”. As shown in FIG. 4, the question items selected by the question selection unit 111 include a plurality of questions, options for answers thereto, and a score linked to each option. The question selection unit 111 causes the in-vehicle monitor 2 to sequentially display the acquired question and the option for the answer.

  The answer acceptance unit 112 accepts the driver D's answer to the question selected by the question selection unit 111 and displayed on the in-vehicle monitor 2. For example, as shown in FIG. 4, the first question to be presented to the driver D who has a history of "left side view narrowing" is "Do you face front and can see the left side mirror?" There are three answer options: "1: all visible", "2: more than half visible", and "3: invisible". Since the in-vehicle monitor 2 according to the embodiment includes the touch panel, the driver D can answer by tapping the option displayed on the in-vehicle monitor 2. The answer acceptance unit 112 accepts an option selected by the driver D tapping the in-vehicle monitor 2 as the driver D's answer to the question.

  The support system changing unit 113 changes the setting of the driving support system 5 provided in the vehicle V based on the content of the driver D's answer. For example, when the driver D has a history of “left side view narrowing” and the answer to the question can confirm the “left side view narrowing” symptom, the support system changing unit 113 Expand the sensing range. As described above, the information processing apparatus 1 according to the embodiment can provide the driving support technology according to the inquiry result of the driver.

  As described with reference to FIG. 4, the question database comprises fields storing scores associated with each option. The answer acceptance unit 112 calculates a cumulative score, which is the sum of the scores linked to the option, based on the option answered by the driver D, and at the same time, converts the answer of the driver D into a radar chart. The answer acceptance unit 112 creates the calculated cumulative points and the radar chart, and outputs the radar chart to the support system changing unit 113, the notification unit 114, the drivability determination unit 115, and the start prohibition unit 116.

  FIG. 5: is a figure which shows typically an example of the radar chart which the answer reception part 112 which concerns on embodiment produces. FIG. 5 shows an example of a radar chart when there are eight questions. The storage unit 10 associates and stores in advance a plurality of medical conditions with the shape of the radar chart in the case of having each medical condition. The support system changing unit 113 can estimate the symptom of the driver D by comparing the radar chart acquired from the response receiving unit 112 with the radar chart stored in the storage unit 10.

  FIG. 6 is a view schematically showing a data structure of a setting change database stored in the storage unit 10 according to the embodiment. The setting change database shown in FIG. 6 includes cumulative points regarding the questions presented to the driver D who has a history of “left side view narrowing”, measures to be performed by the support system changing unit 113, and advice (advice) for the driver D. It is stored in association with it. The setting change database is stored in the storage unit 10, and is managed by the support system change unit 113.

  As shown in FIG. 4, in the question database according to the embodiment, smaller points are assigned to options that are more important for securing the safety of the driver D. Therefore, when the cumulative number of points acquired from the response receiving unit 112 is small, the support system changing unit 113 changes the setting of the driving support system 5 so as to enhance the safety of the driver D more than the case where it is large.

  Further, the support system changing unit 113 also refers to the radar chart created by the response receiving unit 112, and considers a balance that can not be determined only by the cumulative number of questions. For example, even if the accumulated score maintains the same score, the support system changing unit 113 can detect the possibility that the medical condition of the driver D has changed by referring to the breakdown. In that case, even if there is no indication from the doctor, the support system changing unit 113 can take measures such as increasing the score of the Nth question item in FIG.

  The support system changing unit 113 changes the setting of the driving support system 5 by referring to the setting change database based on the accumulated points acquired from the answer receiving unit 112. In the example of the setting change database for “left side visual field narrowing” shown in FIG. 6, when the cumulative score is 15 points or more, the support system changing unit 113 does not perform any special treatment. When the cumulative number of points is between 6 and 10, the support system changing unit 113 changes the setting of the driving support system 5 so as to expand the scanning range of the sensor on the left side in the traveling direction of the vehicle V.

  The notification unit 114 notifies the driver D of the selected advice based on the content of the driver D's answer. Specifically, the notification unit 114 refers to the setting change database on the basis of the accumulated points acquired from the response receiving unit 112 to acquire advice to be notified to the driver D and causes the in-vehicle monitor 2 to display the advice.

  FIG. 7 is a diagram showing an example of the advice displayed by the in-vehicle monitor 2 according to the embodiment. As shown in FIG. 7, since the driver D can confirm the advice based on his / her health condition, he can obtain awareness and concrete measures for safe driving.

  The drivability determination unit 115 determines drivability of the vehicle V by the driver D based on the contents of the driver D's reply. Specifically, the drivability determination unit 115 prohibits the driver D from driving the vehicle V when the accumulated score acquired from the answer reception unit 112 is between 0 and 3 points. In the case where the driving availability determination unit 115 determines to prohibit the driver D from driving the vehicle V, the notification unit 114 notifies that fact to a predetermined contact. Thus, the information processing apparatus 1 can provide a trigger for a person such as a family who has received a notification from the vehicle V to confirm the state of the driver D.

  When the operation permission determination unit 115 determines to prohibit the driver D from driving the vehicle V, the start prohibition unit 116 stops the engine of the vehicle V and prohibits the start of the engine. For example, when the driver D is in a state of mental loss, it is considered that the driver D can not accurately answer the question displayed on the in-vehicle monitor 2 by the question selection unit 111. In such a case, since the cumulative score calculated by the answer acceptance unit 112 is close to 0, the drivability determination unit 115 prohibits the driver D from driving the vehicle V. As a result, the start prohibition unit 116 prohibits the start of the engine of the vehicle V. Thereby, the information processing apparatus 1 can ensure the safety of the driver D more reliably.

  The drivability determination unit 115 may determine the drivability of the vehicle V by the driver D by acquiring and analyzing the image of the driver D captured by the in-vehicle sensor 3. For example, when a symptom such as a myocardial infarction occurs while the driver D is driving the vehicle V, the driver D is said to be in a crouched posture. The drivability determination unit 115 analyzes the posture of the driver D using a known posture analysis engine, and prohibits the driving of the vehicle V when the driver D is crouched. When the driving of the vehicle V is prohibited while the vehicle V is traveling, the drivability determination unit 115 notifies the support system changing unit 113. The support system changing unit 113 changes the driving support system 5 of the vehicle V to the automatic driving mode, moves the vehicle V to a safe place such as a road shoulder, and stops the engine. Thereby, when it becomes difficult to continue the operation of the vehicle V, the safety of the vehicle V can be secured.

<Processing Flow of Information Processing Device 1>
FIG. 8 is a flowchart for explaining the flow of information processing performed by the information processing device 1 according to the embodiment. The processing in this flowchart is interlocked with, for example, when the driver is seated at the driver's seat and the ignition switch is turned on, and starts when the information processing apparatus 1 is activated.

  The personal information acquisition unit 110 acquires personal information of the driver D before the driver D starts the engine of the vehicle V (S2). The question selection unit 111 searches data of the driver database based on the driver's D personal information. As a result of the search, when the driver D has a medical history (Yes in S4), the question selection unit 111 reads out a question suitable for the medical history of the driver D from the question database and causes the in-vehicle monitor 2 to display the question (S6).

  The answer acceptance unit 112 accepts the driver D's answer to the question displayed on the in-vehicle monitor 2 by the question selection unit 111 (S8). Until the question is ended (No in S10), the question selecting unit 111 and the answer accepting unit 112 continue the processing of step S6 and step S8.

  If the driver D does not have a medical history (No in S4), the question selecting unit 111 reads a general question from the question database in consideration of the age of the driver D and causes the in-vehicle monitor 2 to display the general question (S12). The answer acceptance unit 112 accepts an answer of the driver D in response to the question displayed on the in-vehicle monitor 2 by the question selection unit 111 (S14). Until the question is ended (No in S16), the question selecting unit 111 and the answer accepting unit 112 continue the processing of step S12 and step S14.

  When the question displayed by the question selection unit 111 ends (Yes in S10, Yes in S16), the drivability determination unit 115 determines whether the driver D can drive the vehicle V based on the answer accepted by the answer acceptance unit 112. (S18). When the driving availability determination unit 115 permits the driver D to drive the vehicle V (Yes in S20), the support system changing unit 113 determines the driving support system 5 of the vehicle V based on the answer received by the answer accepting unit 112. Change the setting of (S22). The notification unit 114 causes the in-vehicle monitor 2 to display an advice when the driver D drives based on the answer received by the answer receiving unit 112 (S24).

  When the drivability determination unit 115 prohibits the driver D from driving the vehicle V (No in S20), the start prohibition unit 116 prohibits the start of the engine of the vehicle V (S26). The notification unit 114 notifies a message indicating that the driver D has prohibited the driving of the vehicle V, to a predetermined contact specified in advance via the communication device 4 (S28). When driver D presents symptoms of dementia or loss of mind, the time for the question selection unit 111 and the answer reception unit 112 to continue the question and answer until the approval notification is given from the predetermined contact information. It also assumes how to earn money.

  When the answer acceptance unit 112 causes the in-vehicle monitor 2 to display the advice or the notification unit 114 makes a notification, the processing in this flowchart ends.

  As described above, according to the information processing apparatus 1 according to the embodiment, it is possible to provide the driving support technology according to the inquiry result of the driver.
