  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block configuration diagram showing an embodiment of an operation status confirmation system according to the present invention. The driving status confirmation system according to the present embodiment includes various devices mounted on the vehicle 10 side and an information processing device 30 provided separately from the vehicle.

  A plurality of biological sensors 12, a plurality of vehicle sensors 14, a VICS (Vehicle Information and Communication System) 16, a navigation system 18, an in-vehicle information processing device 20, and a communication device 22 are mounted on the vehicle 10. The biometric sensor 12 is directly attached to the driver or indirectly measures the physical condition of the driver. In the present embodiment, an electrocardiographic sensor, a sweat sensor, and a blood pressure sensor are used. The vehicle sensor 14 detects the state of the vehicle. In the present embodiment, the vehicle traveling speed, acceleration, driver's accelerator pedal operation, and the like are detected. Each sensor 12 and 14 can be realized using existing technology. The in-vehicle information processing device 20 is a device that can be realized by a general-purpose information processing device. The information storage unit 24 is provided as a storage unit such as an external storage device, and stores data measured by the biological sensor 12 as biological information. Similarly, data detected by the vehicle sensor 14 is stored as vehicle information. Further, the road traffic information received by the VICS 16 and the travel route of the vehicle detected by the navigation system 18 are stored as route information. The display processing unit 26 displays information stored in the information storage unit 24 on a screen mounted on the navigation system 18. The communication device 22 transmits information stored in the information storage unit 24 to the information processing device 30 via the network.

  On the other hand, the information processing device 30 is a device realized by, for example, a personal computer (PC) at the driver's house, a mobile phone owned by the driver's family, a PC, or the like. The information processing apparatus 30 includes an information receiving unit 32, an information storage unit 34, a mental state determination unit 36, and a display processing unit 38. The information receiving unit 32 receives information sent from the vehicle 10 and stores it in the information storage unit 34. The mental state determination unit 36 determines the driver's mental state based on the biological information sent from the vehicle 10. The display processing unit 38 displays the information stored in the information storage unit 34 and the determination result by the mental state determination unit 36 on a screen (not shown).

  The present embodiment is characterized in that a system can be configured easily and inexpensively by using an existing apparatus, and more effective information can be provided by effectively combining information to be handled. It is. Hereinafter, the operation of the present embodiment will be described.

  For example, it is assumed that the vehicle travels from home to a hot spring area. Therefore, when the driver gets into the vehicle and starts traveling, the biological sensor 12 starts measuring biological information such as electrocardiographic data, and the vehicle sensor 14 starts detecting vehicle information such as vehicle speed, The navigation system 18 starts recording the travel route. In addition, the VICS 16 starts collecting road traffic information on the traveling road. The in-vehicle information processing device 20 collects and stores various information sent from the biosensor 12 and the like in the information storage unit 24 from the start of travel until it arrives at the hot spring resort that is the destination. . The biometric data value at the start of travel is stored as an initial value and is used as a reference value for determination by a mental state determination unit 36 described later.

  The communication device 22 transmits information stored in the information storage unit 24 to the information processing device 30. In the present embodiment, as a mode for displaying information, a real-time mode that is performed concurrently with data collection and a collective mode that is performed collectively after data collection are prepared. In the real-time mode, the communication device 22 needs to transmit information sequentially in order to display information in parallel with data collection. However, in the collective mode, if the communication device 22 finishes transmitting information before displaying information, Therefore, it may be transmitted in parallel with data collection or may be transmitted in a lump after data collection. Subsequently, processing in the information processing apparatus 30 will be described. Here, a case where information display in the collective mode is selected will be described as an example.

  When the information accumulated from the departure of the vehicle 10 to the arrival at the destination is sent from the vehicle 10, the information receiving unit 32 stores the information in the information storage unit 34. The display processing unit 38 displays the stored information on the screen. An example of this display is shown in FIG.

  Fig. 2 shows the home of the departure point and the hot spring area that is the destination. The vehicle traveled from the home through the city, traveled on the highway, and traveled on the mountain road to arrive at the destination. I understand. The display processing unit 38 can grasp the route to the destination from the route information and displays it in the form illustrated in FIG.

  Further, the display processing unit 38 displays the driver's biometric information and vehicle information at the travel point in a balloon from a certain point on the travel path as shown in FIG. FIG. 2 shows an example in which blood pressure is displayed as biological information and vehicle speed is displayed as an example of vehicle information. In this way, since the biological information and vehicle information at the point are displayed in association with a certain point on the road, the blood pressure increased because of excessive speed or a mountain road that requires driving skill It is possible to identify the cause of the fact that the vehicle was traveling. As a result, the next time you go to the same hot spring resort, you can use it to select an appropriate route, such as traveling at a reduced speed, or detouring the mountain road and selecting a flat road. Moreover, since the biometric information is displayed, it can be used for the health management of the driver.

  In the present embodiment, road traffic information is collected, and this information may be displayed together with biometric information and the like. As a result, the blood pressure increased because the selected road was congested, and it is possible to take measures such as shifting the time when heading to the same hot spring resort next time. If the cause of the traffic jam is an accident, it can be determined that the same route will be used at the same time next time.

  According to the present embodiment, the driver's physical condition is not only displayed as described above but also displayed along with the vehicle information and road traffic information corresponding to the traveling road. It can be analyzed more accurately.

  By the way, although the example which displays the information in two traveling points is shown in FIG. 2, in this Embodiment, information can be displayed as follows. The first display method allows the user to designate a display point, and displays biometric information and the like of the designated point. In the second display method, a reference value such as blood pressure is set in advance, and biometric information or the like at a point exceeding the reference value is displayed. In this case, since it is assumed that the reference value is exceeded in a continuous range instead of a single point, the color of the corresponding range is displayed differently. Thereby, for example, a driver with hypertension can be made to select a route that does not include the range in the next time. In addition, the biometric information displayed in this case may be an average value in the range or a maximum value (minimum value), and is selected so that useful information can be provided.

  As described above, since the biological information and the like are displayed in correspondence with the travel route, in the case of information presentation in the collective mode, it is possible to provide information useful for the next and subsequent driving. Next, the case of information display in the real time mode will be described.

  In the real time mode, information is sequentially displayed as described above. In the case of the collective mode, the driver himself can confirm later, but the real-time mode is a display mode useful for the driver's family rather than the driver himself. That is, the display screen shown in FIG. 2 is sequentially drawn on the mobile phone or PC used by the family, but in the real-time mode, the biometric information and the like are updated in real time. The health status of the driver can be monitored sequentially. Accordingly, the driver's family can give an instruction to reduce the traveling speed or change the traveling path, for example, when the driver has hypertension.

  In this embodiment, display can be performed in both the collective mode and the real-time mode, but only one of them may be displayed. However, in the real-time mode, the information storage unit 34 is not an essential configuration requirement.

  In the present embodiment, in addition to the display shown in FIG. 2, a display screen for information generated by the mental state determination unit 36 is provided. An example of this display is shown in FIG.

  FIG. 3 shows an example in which the vertical axis is “sweat” in FIG. 3A, “blood pressure” in FIG. 3B, and the horizontal axis is “heartbeat”. These are data items measured by the biosensor 12. The origin S of the coordinate axes is each value (initial value) of the biological information at the start of traveling. The coordinates shown in FIG. 3A indicate that the body information when the heart rate increases and sweating increases is in a state of “cutting and tension”. The body information when the heart rate decreases and sweating increases indicates that the body is in a “bad physical condition” state. Also, the coordinates shown in FIG. 3B indicate that the body information when the heart rate is increased and the blood pressure is increased is in a state of “cutting and tension”. The body information when the heart rate is lowered and the blood pressure is lowered indicates that the patient feels “sleepy”.

  The mental state determination unit 36 determines the driver's mental state based on the biological information represented by the heart rate and the like. For this purpose, the data value (initial value) at the start of driving is used as a reference, for example, during driving. Each of the obtained values represents a mental state such as “cutting, tension” described above by an increase / decrease rate with respect to the initial value.

  Here, in this embodiment, this mental state is represented by two display modes. The first display mode is indicated by a line L so that the temporal transition of the mental state can be seen as shown in FIG. In this example, the driver feels nervous after the start of running, but then gradually recovers calm. However, it can be grasped again that the state transitions to a mental state of storm and tension. On the other hand, the second display mode is indicated by a point P so that the mental state at a certain point can be seen as shown in FIG. In this example, it can be grasped that sleepiness is felt during traveling at a certain point. The point where the mental state is displayed may be designated on the screen shown in FIG. In the present embodiment, two display modes are shown in FIGS. 2 and 3, but they may be displayed on a single screen.

  According to the present embodiment, the physical state and mental state of the driver can be confirmed not only inside the vehicle but also outside the vehicle as described above. Of course, it is not necessary to limit to the outside of the vehicle, the in-vehicle information processing apparatus 20 is provided with the mental state determination unit 36, and the display processing unit 26 displays the information illustrated in FIGS. 2 and 3 on the display screen of the navigation system 18. Also good.

  In the present embodiment, biometric information and vehicle information as well as road traffic information and mental state are displayed in correspondence with the traveling road, and the information display form is limited to FIGS. Is not to be done.

  In addition, the present embodiment can be used for the optimization of driving by displaying the biological information of the driver, and also for the health management of the driver, etc. Can also be applied. That is, when the passenger has a disease such as hypertension, the health condition of the passenger can be constantly monitored.

It is the block block diagram which showed one Embodiment of the driving | running condition confirmation system which concerns on this invention. It is the figure which showed the example of a screen when displaying biometric information and vehicle information corresponding to a travel path in this Embodiment. It is the figure which showed the example of a screen when displaying a driver | operator's mental state in this Embodiment.
