[0025]
The mobile phone interface unit 11 is provided to perform data communication and voice communication through the mobile phone with a mobile phone (not shown) connected thereto.
[0026]
The Bluetooth interface unit 12 is for data communication with a terminal installed in the vehicle, and a sensor unit 18 is provided as one of the terminals. This sensor unit 18 constitutes the data collection means referred to in the present invention together with the weight scale 13, and is attached to the steering wheel of the vehicle. Specifically, the sensor unit 18 includes a body fat scale 19, a thermometer 20, a sphygmomanometer 21 (all corresponding to sensors) disposed on the steering wheel ring, and a data transmission unit 22 disposed on the steering wheel boss. Become.
[0027]
The body fat scale 19 has a pair of electrodes disposed on the left and right sides of the steering wheel ring (both left and right sides in the straight position), and each electrode is gripped by the left and right hands of the vehicle driver. Then, the body fat percentage is measured and the measurement result (health guideline data) is given to the data transmission unit 22. The thermometer 20 measures the temperature of the electrode for the body fat scale 19, for example, and gives the temperature to the data transmission unit 22 as a measurement result (health guideline data) indicating the body temperature of the vehicle driver.
[0028]
The sphygmomanometer 21 measures blood pressure using, for example, a pulse wave transmission time (PWTT: Pulse Wave Transmit Time) until the blood pulse wave accompanying the heart contraction reaches the fingertip from the heart in the human body, An electrode sensor for detecting the potential change that occurs when the heart beats and detecting the heart's contraction timing, and detecting the change in blood flow of the fingertip with infrared rays and capturing the timing when the pulse wave reaches the fingertip The blood pressure is measured by calculation based on the pulse wave propagation time detected by these sensors, and the measurement result (health guideline data) is given to the data transmission unit 22. However, since there is an individual difference in pulse wave propagation time, personal data (maximum blood pressure, minimum blood pressure, pulse rate) is collected in advance by a separately prepared blood pressure monitor (for example, a blood pressure monitor using an oscillometric method) The personal data is stored in the external memory 6, and the sphygmomanometer 21 is configured to perform blood pressure measurement using the personal data. In this case, personal data needs to be read in advance on the sphygmomanometer 21 side, but such a necessity is necessary when the navigation ECU 2 is configured to store a blood pressure calculation program based on the pulse wave propagation time. Disappear. The electrode sensor and the infrared sensor of the sphygmomanometer 21 are arranged at positions adjacent to one of the electrodes forming a pair of the body fat scale 19. The personal data measured by a separately prepared blood pressure monitor may be directly written in the external memory 6 formed of a flash memory card or the like, but is transmitted to the navigation ECU 2 through the Bluetooth interface unit 12 and the navigation ECU 2 The received personal data may be stored in the external memory 6.
[0029]
The data transmission unit 22 has a built-in Bluetooth standard communication interface so that data communication with the navigation ECU 2 is possible. In particular, each time the data transmission unit 22 receives a data request signal transmitted from the navigation ECU 2 through the Bluetooth interface unit 12, for example, the data transmission unit 22 transmits each measurement result by the body fat meter 19, the thermometer 20, and the sphygmomanometer 21 to the Bluetooth interface. It is configured to transmit to the navigation ECU 2 through the unit 12.
[0030]
On the other hand, the weight scale 13 is composed of, for example, a pressure sensor installed on the driver's seat, measures the weight of the seated driver (actually a relative value proportional to the driver's weight), and the measurement result (Health guideline data) is output to the navigation ECU 2.
[0031]
Here, in addition to the basic map display function of executing the map matching process for positioning the current position on the map, the navigation ECU 2 receives point data such as a destination and a waypoint through the operation switch group 8. In addition, the route calculation function of performing a route search operation from the current position to the destination based on the point data using, for example, the Dijkstra method, and displaying the guide route set based on the route search result on the map screen Well-known support functions such as a route guidance function (including a so-called reroute search function) and a route guidance function for performing various guides by voice or display based on a guidance route obtained by this function are provided.
[0032]
In addition to this, the navigation ECU 2 has a well-known telephone number search function, postal code search function, search function using a unique code, 50 sound search function, genre search function, nearest facility search function, destination registration function, A wide variety of support functions such as an information display function for displaying a sightseeing area and a recommended drive course, a point registration function, and the like are set. As functions directly related to the gist of the present invention, the sensor unit 18 and A function for diagnosing the health condition of the vehicle driver based on the output from the scale 13 is set. FIG. 2 shows control contents for such a health condition diagnosis function, which will be described below together with related actions. Note that the flowchart of FIG. 2 is simplified to the extent that the gist of the present invention can be grasped, and is actually more complicated control content or control content different from the illustrated one. The control is executed in parallel with the map display function.
[0033]
In FIG. 2, the navigation ECU 2 determines whether or not a predetermined data collection timing (for example, a timing for every predetermined time) has come (step A1). When the data collection timing comes, the Bluetooth interface unit 12 transmits a data request signal to the data transmission unit 22 of the sensor unit 18 (step A2). In this case, in the data transmission unit 22 that has received the data request signal, the measurement results by the sensor unit 18 (respective measurement results by the body fat meter 19, the thermometer 20, and the sphygmomanometer 21) are transmitted to the navigation ECU 2 through the Bluetooth interface unit 12. In the navigation ECU 2, after the data request signal is transmitted, the navigation ECU 2 waits until the measurement result from the sensor unit 18 is received or until a predetermined waiting time elapses (steps A3 and A4). ).
[0034]
When the waiting time elapses without receiving the measurement result, the process returns to step A2 to retransmit the data request signal. When the measurement result is received, the measurement result is stored in the external memory 6 as physical condition management data. (Step A5) Further, the measurement result by the weight scale 13 is read and the measurement result is stored in the external memory 6 as physical condition management data at the same timing as the physical condition management data (Step A6). Return to. As a result, physical management data indicating the body fat percentage, body temperature, blood pressure, and weight of the vehicle driver is sequentially stored in the external memory 6 at every predetermined data collection timing. Of the physical condition management data, the measurement results of body temperature, blood pressure, and weight are unavoidable to some extent when viewed as absolute values, but the relative temperature, blood pressure, and body weight of the vehicle driver are unavoidable. The data indicating the transition has sufficient reliability.
[0035]
On the other hand, in a period other than the data collection timing (a period in which “NO” is determined in step A1), it is determined whether or not the health condition of the vehicle driver can be diagnosed (step A7). This determination is made, for example, based on whether or not the physical condition management data stored in the external memory 6 corresponds to a measurement result of a predetermined number of times or more, and thereby the sensor unit 18 and the weight scale 13. The influence of the measurement error is eliminated.
[0036]
When it is determined that the health condition cannot be diagnosed, the process returns to step A1, but when it is determined that the condition is possible, the physical condition management data is read from the external memory 6 (step A8), and thereafter the health condition diagnosis routine A9 is executed. . In this routine A9, the health condition of the vehicle driver is determined based on the physical condition management data. Specifically, each state in which body temperature and blood pressure are higher than a normal amount by a predetermined amount or abnormally high, a state in which body fat percentage is higher than a predetermined upper limit (and a lower state) ) Based on the weight increase / decrease state, etc., it is determined whether any consideration or countermeasure is required for the health condition of the vehicle driver.
[0037]
Thereafter, it is determined whether or not the diagnosis result in the health condition diagnosis routine A9 has an abnormal state (a state that requires some consideration or countermeasure) (step A10). If there is no abnormality, the process returns to Step A1 as it is, but if there is an abnormality, the symptom operation routine A11 is executed and then the process returns to Step A1. In the symptomatic operation routine A11, for example, the following processing is performed.
[0038]
(1) When the body temperature or blood pressure is higher than the normal amount by a predetermined amount or when both the body temperature and blood pressure are higher than the normal amount by a predetermined amount, it is determined that the vehicle driver is not in good health. The operation of notifying the state of poor physical condition and the measurement result of body temperature and blood pressure is performed through one or both of the display device 7 and the sound output device 9. In this case, an operation for switching the display contents on the display device 7 to a display form that can be clearly seen (for example, a display form in which display characters are made larger than normal), and an operation for raising the guidance volume through the audio output device 9 from the normal time. Do one or both of the following: In addition, when route guidance to the destination set by the navigation function is being executed, roads that require less burden for driving the vehicle (for example, roads with low traffic volume, roads with guardrails, independent roads) Routes with priority on roads with sidewalks, roads with few left and right turns, toll roads, wide roads, roads with few traffic lights, roads without crossings, roads with median strips, etc. Switch to the state to be performed. Note that switching to such a state is not necessarily performed automatically, and may be performed for the first time when there is an agreement (operation) of the vehicle driver.
[0039]
(2) When the body temperature and blood pressure are abnormally higher than normal, or when both the body temperature and blood pressure are abnormally higher than normal, the vehicle driver is in a very poor physical condition. An operation of making a determination and reporting the determination result (diagnosis result) to a preset contact (for example, home or work) through the mobile phone interface unit 11 and a mobile phone connected thereto is performed. In addition, when there is such a report, it can be picked up from home or work. In addition, for example, at home, it is used as a reference when determining the meal menu for the day (a menu that gives appetite even for those who are in poor physical condition, or a menu that takes nutrition into consideration). Further, when the health condition of the vehicle driver is a state requiring medication (for example, an abnormal rise in body temperature), the above judgment result and data such as a past history of the vehicle driver stored separately are stored. In addition to reporting to the nearest pharmacy or hospital through the mobile phone, at least one of the operation of displaying the location of the pharmacy or hospital on the road map screen in the display device 7 and the route guidance to the pharmacy or hospital is performed. . In addition, one of the lights (tail lamp, direction indicator lamp, etc.) installed in the vehicle and separately provided notification means (for example, a dedicated indicator) Control to notify the following vehicle through both.
[0040]
(3) When the body fat percentage is higher than the limit, when the vehicle driver sets the destination by the navigation function, a point within a range that can be walked to the destination (parking lot or other parking available) For example, the voice output device 9 is used to inquire whether or not it is possible to set the destination as a destination, and when the vehicle driver agrees, the point is set as the destination. Further, when setting the destination, it is recommended that the user goes to the destination by walking or using public transportation without using the vehicle through the display device 7 or the voice output device 9.
[0041]
In short, according to the present embodiment, the following operations and effects can be achieved. That is, health guideline data (body fat percentage, body temperature, blood pressure, body weight) that is a measure of the health condition of the vehicle driver is collected by the sensor unit 18 and the weight scale 13, and the collected health guideline data is car navigation. It is periodically read by the navigation ECU 2 of the device 1 and stored in the external memory 6 as physical condition management data. The navigation ECU 2 diagnoses the health condition of the vehicle driver based on the physical condition management data stored in the external memory (that is, data indicating the transition of the health condition of the vehicle driver), and displays the diagnosis result. The notification is made through one or both of the device 7 and the audio output device 9. As a result, changes in the health condition of the vehicle driver (basal body temperature fluctuation, blood pressure fluctuation, etc.) can be continuously monitored. This makes it possible to detect the deterioration of the health condition in advance and It is possible to reliably notify the driver himself / herself through the display device 7 and the voice output device 9 of the health condition of the vehicle driver during driving. In addition, since the existing display device 7 and audio output device 9 can be used for such notification, the system configuration can be simplified. Further, since the function of diagnosing the health condition of the vehicle driver is shared by the navigation ECU 2 provided for display control of the road map screen, the system configuration can be further simplified.
[0042]
Since the sensor unit 18 for collecting the body fat percentage, body temperature and blood pressure data of the vehicle driver is provided on the steering wheel of the vehicle, the data is collected with the vehicle driver holding the steering wheel. it can. Moreover, since the scale 13 for collecting the weight data of the vehicle driver is provided in the driver seat, the data can be collected in a state where the vehicle driver is seated on the driver seat. For this reason, it becomes possible to continuously collect the health guideline data without extra operation during driving of the vehicle, and the convenience on the side of the vehicle driver is improved.
[0043]
When the route guidance to the destination is performed by the navigation function, if the vehicle driver is in a poor physical condition, the route guidance is performed by selecting a road with less burden required for driving the vehicle. It becomes possible to prevent a situation in which the burden on the person becomes heavy, and is effective in making up for the poor physical condition.
[0044]
When the vehicle driver is in a poor physical condition, an operation of switching the display content on the display device 7 to a display form that can be clearly seen and an operation of raising the guidance volume through the audio output device 9 from the normal time are performed. Thus, it becomes possible to reduce the burden on the vehicle driver required for confirming the display contents by the display device 7 and confirming the guidance voice by the sound output device 9, which is effective in compensating for the poor physical condition.
[0045]
When it is diagnosed that the vehicle driver's health condition is very bad, the diagnosis result is reported to a preset contact information (home, work, etc.) via the mobile phone, so the vehicle driver's health condition deteriorates. In such a case, effective measures such as picking up a person or changing the meal menu of the day can be taken. In addition, if the vehicle driver's health condition requires medication, the diagnosis results and past data on the vehicle driver are reported to the nearest pharmacy or hospital via a mobile phone, etc. At least one of the operation of displaying the position of the pharmacy or hospital on the road map screen in the display device 7 and the operation of guiding the route to the pharmacy or hospital is performed. As a result, medication and treatment for the vehicle driver can be performed quickly, which can greatly contribute to the recovery of the health condition. Furthermore, in this case, the fact that the vehicle driver's health has deteriorated is notified to the succeeding vehicle through one or both of the lights installed in the vehicle and the separately provided notification means. The driver side of the car can understand the cause of a driving state different from the normal driving state of the vehicle traveling forward (for example, an abnormal decrease in driving speed), and can contribute to his own safe driving.
[0046]
In addition, this invention is not limited to an above-described Example, The following deformation | transformation or expansion is possible.
In response to the control function of the navigation ECU 2, a message prompting the vehicle driver to take a break every time a predetermined time is reached in the vehicle traveling state (for example, every time the traveling distance becomes a set distance) or one of the display device 7 and the audio output device 9 Function to output through both, and function to change the message output time based on the result of diagnosing the health condition of the vehicle driver (for example, the function to advance the message output time when the health condition is bad, or while driving on the expressway May be provided with a function for recommending a break for each service area or parking area. According to this configuration, since a message prompting the vehicle driver to take a break is output every time a predetermined time is reached in the vehicle running state, it is possible to prevent a situation in which the fatigue of the vehicle driver increases. In addition, since the output timing of the message is changed based on the result of diagnosing the health condition of the vehicle driver, it is possible to prompt the vehicle driver to take a break at the optimum time considering the health condition. It becomes useful in practical use.
[0047]
Each time the engine of the vehicle is started, the vehicle driver is asked about the physical condition of the day through the voice output device 9, for example, “How are you feeling today?” And the response (“I feel bad”, “I ’m hungry” Is received through the voice recognition unit 5 and the response content is converted into data that can be recognized by the navigation ECU 2 and stored in the external memory 6. It can be used as a reference for diagnosis of health condition. In this case, when the vehicle driver's health condition requires medication, the above response should be made when reporting the diagnosis result and the vehicle driver's medical history data to the nearest pharmacy or hospital. It is good also as a structure which reports content data simultaneously. Furthermore, when it is determined that the health condition of the vehicle driver is particularly deteriorated, the fact may be notified to the management center of the Mayday system.
[0048]
The navigation function stores the characteristics of the normal driving operation of the vehicle driver (acceleration method, curve curve, etc.), and if the actual driving operation contents are significantly different from the stored characteristics, blood pressure, A configuration may be adopted in which the presence or absence of drinking or an excited state of the vehicle driver is determined based on body temperature or the like. When it is determined that the person is drinking, when it is determined that the person is in an excited state, or when it is determined that his / her physical condition is extremely poor, the vehicle traveling speed is regulated so as not to exceed a certain level, or registered in advance. It may be configured to perform control such as reporting to a surrogate driver, or only automatic vehicle driving considered to be practical in the future may be performed.
[0049]
