Description

  The present invention provides a health management support device and health management that can obtain physical information useful for health management, etc. using vehicles such as automobiles, and can notify information useful for health management as needed. About the system.

With the progress of the functions of automobiles, a technique for monitoring a living body (passenger: person to be measured) in a passenger compartment and a technique for managing health have been proposed (see Patent Document 1).
In this technique, by using an automobile as a measuring device, daily health management becomes easy for a person to be measured who uses the automobile on a daily basis.
JP 2005-168908 A

  However, in these conventional techniques, for example, when the condition of the person being measured is measured immediately after getting in the car, the state changes from walking or running to a sitting state in a short time. In addition, there is a problem that the blood pressure value is different from a resting state (that is, a state suitable for measurement of a normal body state with little disturbance).

  Also, for example, in winter, the vehicle room temperature is very low, so if you measure immediately after getting on the vehicle, the effect of the room temperature is great, and accurate physical information effective for health management cannot be obtained. there were.

  Furthermore, when measuring the physical condition during driving, the blood pressure value and heart rate are disturbed by driving operation, tension, emotion, etc. (ie, disturbance caused by driving action becomes large), When stored as physical information, there is a problem that the variation becomes large, and it may not be accurate information.

Therefore, it has been difficult to utilize the physical information measured every day when getting on the vehicle as it is for health management.
The present invention has been made to solve the above-mentioned problems, and a health management support apparatus capable of acquiring accurate body information of a measurement subject useful for health management in a passenger compartment of an automobile and the like The purpose is to provide a health management support system.

  (1) According to the invention of claim 1, in the health care support device that detects the physical state of the person to be measured who has boarded the vehicle as the physical information by the detection means (various sensors or the like), based on a predetermined determination condition, Condition determining means for determining whether it is time to detect the physical information of the person to be measured by the detecting means is provided.

  In the present invention, whether or not a timing suitable for detecting physical information (for example, a state where the influence of disturbance such as a driving operation is as low as possible and which is as quiet as possible), for example, whether a predetermined determination condition is satisfied (for example, as described later) Therefore, there is an effect that the variation in physical information necessary for health management is small and the accuracy thereof is high.

  When it is determined that the timing is suitable for detecting physical information, highly accurate physical information can be obtained by performing processing for detecting physical information. The information obtained by the detection is stored, for example, in storage means in the vehicle, or communicated to a server outside the vehicle via the Internet.

  (2) The invention of claim 2 is a health management support in which the detection means (various sensors, etc.) detects the physical state of the person on the vehicle as physical information and stores the detected physical information in the storage means. The apparatus includes condition determining means for determining whether or not it is time to store the physical information of the measurement subject detected by the detecting means in the storage means based on a predetermined determination condition.

  In the present invention, whether the timing is suitable for storing physical information (for example, a state where the influence of disturbance is as low as possible and is as quiet as possible), for example, whether a predetermined determination condition is satisfied (for example, a heart rate as described later) Therefore, there is an effect that the variation in physical information necessary for health management stored in the storage means is small and the accuracy thereof is high.

  In the present invention, when it is determined that it is a timing suitable for storing physical information other than at the time of storage and it is determined that the timing is suitable for storing physical information, the physical information at that timing is stored in the storage means. Can be remembered.

(3) In the invention of claim 3, when it is determined by the condition determination means that the timing is reached, the fact is notified.
In the present invention, if it is determined that it is time to detect or store physical information, this is displayed, for example, on a monitor (display), or notified by sound or voice through a speaker. Therefore, the measurement subject can receive the notification and instruct the detection or storage process of the physical information manually, for example, at the optimum timing.

(4) In the invention of claim 4, when it is determined by the condition determination means that the timing is reached, the processing to be performed at the timing is automatically performed.
In the present invention, when it is determined that it is time to perform the process of detecting or storing physical information, the process is automatically performed, so that there is an advantage that a trouble such as a manual operation is unnecessary.

  (5) In the invention of claim 5, the judgment condition is at least one of time, time since boarding, time since stopping, heart rate, vehicle behavior, vehicle interior temperature, and navigation information. is there.

  The present invention exemplifies determination conditions for determining the timing of performing physical information detection or storage processing. As a result, it is possible to detect or store physical information in a state desirable for measurement (a state where there is little disturbance and is as quiet as possible). A plurality of conditions can be combined.

-Considering the time, for example, by measuring at a predetermined time (and thus a period), the influence of circadian rhythm (daily fluctuation) can be reduced.
・ By taking into consideration the time since getting on and the time after stopping, it is possible to approach a resting state. In other words, when a certain amount of time has elapsed since boarding (for example, when the influence of vehicle behavior or the like is small), or when a certain amount of time has elapsed since stopping, This is because there is little fluctuation and it is considered to be in a stable state.

-Since the activity state of the body can be understood by looking at the change in the heart rate, the influence of disturbance can be eliminated, for example, by measuring at the timing when the fluctuation of the heart rate is reduced.
-If the vehicle behavior such as acceleration / deceleration or turning of the vehicle is large, the blood flow in the human body is affected by the longitudinal G due to acceleration / deceleration and the lateral G due to turning, so the measurement of blood pressure etc. is affected. Variations occur in measurement results. Therefore, by considering the vehicle behavior (for example, by measuring when the change in the vehicle behavior is small), it is possible to detect the body state in a state close to rest.

  -Even if the vehicle interior temperature changes, it is considered that there is a change in the body condition such as heart rate, so by considering the vehicle interior temperature (for example, by measuring when there is little change in the vehicle interior temperature) It is possible to detect the body condition in a state close to rest.

  ・ Measurement under the same conditions is possible by obtaining from the navigation information where you left home or where you left the company. Therefore, since the influence of disturbance (environmental change etc.) can be reduced, the reliability of physical information is improved.

(6) In the invention of claim 6, the determination condition is that a predetermined time or more has elapsed after boarding.
In the present invention, physical information is detected or stored when, for example, 3 minutes or more have elapsed after boarding, so that processing in a more resting state is possible, and the reliability of physical information is improved.

(7) In the invention of claim 7, the determination condition is characterized in that a change in heart rate per unit time is within a predetermined ratio.
In the present invention, since the physical information is detected or stored when the change in the heart rate per unit time (for example, 1 minute) is within 5%, for example, it is possible to perform processing in a more resting state. Reliability is improved.

(8) The invention according to claim 8 is characterized in that the determination condition is during constant speed traveling or stopping.
In the present invention, since physical information is detected or stored when traveling at a constant speed or when the vehicle is stopped, it is possible to perform processing in a more quiet state, and the reliability of physical information is improved.

The state close to rest is considered to be stopping> running, and during running, constant speed running> acceleration / deceleration, straight running> turning.
(9) In the invention of claim 9, the determination condition is characterized in that a change in the passenger compartment temperature per unit time is a predetermined temperature or less.

  In the present invention, since the body information is detected or stored when, for example, the fluctuation of the passenger compartment temperature per minute becomes, for example, 1 ° C. or less, it is possible to perform processing in a more quiet state, and the reliability of the body information Will improve.

(10) In the invention of claim 10, the determination condition is that at least one of heart rate, vehicle interior temperature, and vehicle behavior has passed a predetermined state for one minute or more.
In the present invention, body information is detected or stored when at least one of heart rate, vehicle interior temperature, and vehicle behavior has reached a predetermined state for more than one minute. This makes it possible to improve the reliability of physical information.

(11) The invention of claim 11 is characterized in that a plurality of pieces of physical information indicating physical states at different times are stored per day.
Thereby, a lot of highly reliable data can be collected.

(12) According to the twelfth aspect of the present invention, the physical information measured at the timing determined to be optimal among the plurality of stored physical information is stored as the physical information of the day.
For example, when physical information is measured at two timings of T1 and T2 in one day, when the suitable timing order is T1> T2, the information at the timing of T1 is stored as the physical information of the day. Thereby, the accuracy of physical information can be improved. If there is only information at the timing of T2, the information at the timing of T2 is stored as physical information of the day.

(13) In the invention of claim 13, when there are a plurality of pieces of physical information measured at the timing determined to be optimal, the average value of the plurality of pieces of physical information is stored as the physical information of the day.
For example, when T1 (optimum timing) is in the morning and a plurality of pieces of information are obtained in the morning, the average value is stored as physical information of the day. Thereby, the accuracy of physical information can be improved.

  (14) The invention of claim 14 is characterized in that the condition for determining the optimum timing is at least one of time, navigation information, vehicle behavior, heart rate, and vehicle interior temperature.

The present invention exemplifies conditions for determining the optimum timing, and a plurality of the conditions can be combined.
In the case of time, for example, if the time (and therefore the period) at which the driver state is estimated to be stable is found by daily measurement, for example, the time (period) is selected as optimal.

In the case of navigation information, when it is close to the house or when the road is thick, it can be regarded as optimal (a preferable state for obtaining physical information) as compared to the case where it is not.
-In the case of vehicle behavior, it can be regarded as optimal in the order of stoppage> during constant speed> acceleration / deceleration or turning.

-If the heart rate and the passenger compartment temperature are within a predetermined fluctuation range, they can be regarded as optimum compared to the case where the heart rate and the passenger compartment temperature are not.
(15) The invention of claim 15 is characterized in that the condition for determining that the timing is optimum is matched with the timing that has been optimized previously.

  In the present invention, the timing determined to be optimal can be selected based on the measurement time (period) of the previously measured physical information, the measurement environment (for example, position information of the navigation information, etc.), etc. improves.

  For example, if you have set a mild condition such as “Measure in the morning” and the heart rate is being measured stably near your home, there are many days when you want to use the measurement near your home as the optimal timing. I think that.

(16) The invention of claim 16 is characterized in that the detected physical information is notified by a notification means (for example, a monitor or a speaker).
Therefore, since the person to be measured can know the physical information through the monitor or the speaker, it is possible to take an appropriate measure (for example, receiving a medical examination) according to the notification content.

(17) The invention of claim 17 is characterized in that the display period can be selected when the notification means is a display means.
In the present invention, since the display means can be selected manually, an optimal display can be selected.

(18) The invention of claim 18 is characterized in that at least two periods of one day, one week, one month, half a year, one year, five years, and ten years can be selected as the display period. .
In the present invention, since physical information in a plurality of periods can be displayed, a change in a long span and a change in a short span can be easily understood, and the physical information can be grasped more accurately.

(19) The invention of claim 19 is characterized in that the physical information is stored and displayed in a collective manner according to the time or period when the physical information is obtained.
For example, when the physical information is requested to be old, such as before one year, or when the period is a long span such as one year, storing all the physical information increases the data storage area. The burden of data processing is also increased. In such a case, for example, if data is aggregated and stored like average data every month, old data or data over a long period can be stored in a good manner.

  Similarly, when the time for obtaining physical information is old or long, even if all the data is displayed, it may be difficult to understand. In such a case, for example, if data is aggregated and displayed like average data every month, old data or data over a long period of time can be displayed in a good manner.

  Here, “aggregation” does not display or store all the data, but adopts a representative value such as an average value, selected data, etc. (Data) is displayed or stored.

  (20) In the invention of claim 20, the body information is aggregated based on at least one of the day of the week, the difference from the average value, the time, the navigation information, the vehicle behavior, the heart rate, and the cabin temperature. Features.

The present invention exemplifies a method for collecting physical information.
In the case of aggregation by day of the week, it can be considered that the situation is the same, for example, a method of aggregating (e.g., averaging) data from Monday to Friday.

In the case of aggregation based on the difference from the average value, if the difference is larger than a predetermined value, it is possible to exclude it as an abnormal value and to aggregate (for example, average) only with data within the predetermined value.
In the case of aggregation by time, it can be considered the same situation, for example, a method of aggregating (for example, averaging) morning data.

In the case of aggregating with navigation information, for example, a method of aggregating (for example, averaging) data in a similar place or a similar type of road is considered.
In the case of aggregation by vehicle behavior, a method of consolidating (for example, averaging) data that is considered to be the same situation, for example, data at a constant speed is conceivable.

  -When collecting by heart rate, it is considered that the situation is the same in each state when stopping and driving, so for example, the data during driving with a high heart rate is cut and the remaining data is aggregated ( For example, an average method may be considered.

In the case of aggregation by the passenger compartment temperature, a method of aggregating (for example, averaging) data in a predetermined temperature range considered to be the same situation can be considered.
(21) The invention of claim 21 is characterized in that when physical information is stored or displayed, data indicating daily activity is also stored or displayed.

  In the present invention, for example, when the daily activity amount is known by an acceleration sensor attached to the body or a schedule (for example, indicating time in the workplace or time in the gym), the data is also stored or displayed. To do.

  That is, when displaying physical information, showing the amount of activity is preferable because it makes it easier to understand the meaning of the measured physical information. For example, if the blood pressure is displayed at a high level, it can be understood if it is a period in which the amount of activity is high, but if it is a period in which the amount of activity is low, it can be estimated that there is a cause in the body .

  The amount of activity can be expressed as the time during which the body moves more than a predetermined amount. For example, it can be expressed not by sleeping or resting time but by working or walking time.

  (22) The invention of claim 22 is characterized in that the data indicating the daily activity amount is at least one of navigation information, information by an acceleration sensor, a schedule, and sleep information.

The present invention exemplifies data indicating the daily activity amount.
As navigation information, for example, when the company is in a long time, it can be estimated that there is a large amount of activity.

-It can be estimated that the amount of activity is large when acceleration is large by an acceleration sensor attached to the body.
・ From the schedule, for example, when the time spent in the gym is long, it can be estimated that the amount of activity is large.

-As sleep information, when sleep time is long, for example, it can be estimated that there is little activity amount.
(23) The invention of claim 23 is characterized in that the physical information obtained in the passenger compartment is corrected by physical information obtained outside the passenger compartment.

  For example, heart rate and blood pressure data while riding in the vehicle may differ from the data detected during rest, so that data during boarding is corrected using the data during rest. For example, data such as heart rate and blood pressure is reduced by a predetermined rate. Thereby, a body state can be grasped | ascertained accurately using the data in boarding a vehicle.

(24) In the invention of claim 24, the body information is compared with the body information of the past predetermined period as a reference, and the vehicle is controlled based on the comparison result.
For example, when physical information obtained during boarding of the vehicle is abnormal as compared with past physical information, control is performed to increase safety, such as limiting speed or improving braking performance.

(25) The invention of claim 25 is characterized in that the body information is at least one of body temperature, blood pressure, heart rate, pulse wave information, body weight, blood sugar level, and body fat.
The present invention exemplifies physical information.

-Body temperature can be detected using a non-contact thermosensor using infrared rays.
Blood pressure is estimated from PWV (pulse wave velocity) and pulse wave information. PWV is an amount related to blood pressure, which is obtained from the speed of propagation of heartbeats using an electrocardiographic sensor and a pulse wave sensor (mounted on an arm, finger, etc.). The pulse wave information is obtained by analyzing the pulse wave waveform measured by the pulse wave sensor.

-The heart rate can be obtained by an electrocardiographic sensor or a pulse wave sensor.
-Pulse wave information (pulse rate, blood vessel age, etc.) can be obtained by a pulse wave sensor.
-The weight can be obtained by a sheet sensor or the like.

The blood sugar level can be automatically obtained from a blood sample collected by inserting a needle into a finger or the like.
-Body fat can be calculated | required, for example with the body fat scale connected to a pair of electrode with which steering | stirring was mounted | worn.

(26) The invention of claim 26 is characterized in that at least one kind of processing among detection, storage and notification of physical information is performed on a plurality of passengers.
The present invention exemplifies an object of physical information processing and can be applied not only to the driver but also to other passengers.

(27) The invention of claim 27 is characterized in that the determination condition can be changed manually.
Thereby, it can respond more suitably for each individual, and usability improves.

(28) The invention of claim 28 is characterized in that navigation information is distinguished by several attributes.
By dividing the navigation information into several attributes (types), it is possible to know which attribute the body information is, so that it is easy to understand the meaning of the body information and the reliability is improved.

For example, in the case of an attribute indicating a frequently passing road (for example, an expressway), it is considered that the reliability of the physical information measured at the place is improved.
(29) In the invention of claim 29, the attributes are classified into at least two kinds of attributes among home, workplace, shopping center, restaurant, gym, highway, main road, urban area, hospital, and user set place. It is characterized by.

  The present invention exemplifies the attributes of navigation information. In addition, the weight of this attribute can improve the accuracy of the physical information. For example, since blood pressure and heart rate are usually different between home and a gym, it is possible to correct body information by the difference in this attribute.

  (30) The invention of claim 30 comprises at least the detection means among the health care support apparatus according to any one of claims 1 to 29, a detection means for detecting physical information, and a recording means for recording physical information. This is a health management support device system.

  Therefore, by using a vehicle equipped with this health management support apparatus system, body information can be measured at a suitable timing and used for health management.

  An example (Example 1) of an embodiment of the present invention will be described below with reference to the drawings.

a) First, the overall configuration of the health management support system and its peripheral devices will be described.
FIG. 1 is an explanatory diagram showing the overall configuration of a health management support system to which the present invention is applied.
As shown in FIG. 1, the present embodiment is a health management support system mounted on a vehicle, and various health management sensors that detect the physical state of a person to be measured such as a driver on the vehicle as physical information. 1, a health management support apparatus 3 that performs processing such as calculation for supporting health management of the measurement subject based on the physical information detected by the health management sensor 1, and the health management sensor 1 A display device (monitor) 5 and a speaker 7 are provided for reporting physical information and the like.

  Separately, in order to control the vehicle, various vehicle control sensors 9 that detect the state of the vehicle, and vehicle control that controls the vehicle based on vehicle information detected by the vehicle control sensor 9 and the like. The apparatus 11 includes various actuators 12 (see FIG. 3) that control the vehicle based on vehicle information detected by the vehicle control sensor 11.

Furthermore, the navigation device 13 is mounted on the vehicle, and the navigation device 13 is connected to the monitor 5 and the speaker 7.
The health care support device 3, the vehicle control device 11, and the navigation device 13 are connected to each other and can transmit and receive necessary information.

  As shown in FIG. 2, the health management support device 3 is an electronic control device having a microcomputer as a main part, and includes a well-known ROM 3a, RAM 3b, CPU 3c, input / output unit 3d, and the like, and can rewrite data. In addition, a nonvolatile memory (for example, EEPROM 11e) that can hold data even when the power is turned off is provided. Various health management sensors 1, a monitor 5, and a speaker 7 are connected to the input / output unit 3d. The health management support device 3 can communicate with a server (not shown) via a well-known wireless communication line or the like to transmit / receive information necessary for health management.

  As the health management sensor 1, for example, an electrocardiographic sensor 1 a that detects a heart rate using a pair of electrodes 17 a and 17 b (see FIG. 1) installed on the steering wheel 15, and is attached to the arm of the subject. A pulse wave sensor 1b for detecting a pulse wave or the like, a temperature sensor 1c that can detect the temperature in the passenger compartment or the body temperature of the measurement subject in a non-contact manner (using infrared rays), the presence or absence of the measurement subject's seating, and the seat Examples thereof include a sheet sensor 1d that detects pressure applied to (see FIG. 1).

The body fat percentage can also be measured using the electrodes 17a and 17b. The pulse wave sensor 1b and the health management support apparatus 3 can transmit and receive information and the like wirelessly.
On the other hand, as shown in FIG. 3, the vehicle control device 11 is also an electronic control device having a microcomputer as a main part, and includes a well-known ROM 11a, RAM 11b, CPU 11c, input / output unit 11d, EEPROM 11e, and the like. A vehicle speed sensor 1a and an acceleration sensor 1b are connected to the input / output unit 11d as a vehicle control sensor 1, and various actuators 12 such as a fuel injection device are connected.

b) Next, the contents of control performed on the health management support apparatus 3 and the like will be described.
In the present embodiment, a process of detecting a physical state at an appropriate timing and appropriately storing physical information, which is a detection result, is performed on a person to be measured who has boarded an automobile. This process is started when the ignition key is on.

  As shown in the flowchart of FIG. 4, in step (S) 100, measurement necessary for timing determination is started by a device (such as a sensor) used to determine the timing of detection of a physical state described later.

  Note that what kind of sensor is used differs depending on what judgment condition is used, as will be described in detail later. For example, when the determination is based on the elapsed time after boarding, the presence or absence of seating is detected by the seat sensor 1d, and the time from sitting is measured by the timer. Here, for example, the determination condition 1 is whether or not three minutes or more have elapsed since the user boarded the vehicle.

  In the following step 110, the vehicle behavior is confirmed. Specifically, information from a vehicle control sensor 9 such as a vehicle speed sensor 9a or an acceleration sensor 9b is input, and various vehicle behaviors such as stopping, running at a constant speed, acceleration / deceleration, and turning are confirmed. For example, the condition 2 for determination is that the vehicle is stopped or traveling at a constant speed.

  In the following step 120, the navigation information is confirmed. Specifically, based on information from the navigation device 13, the current travel position, what kind of road the vehicle is traveling, and the like are confirmed. For example, a short distance (for example, within 5 km) from the home is set as the determination condition 3.

  In subsequent step 130, it is determined whether or not it is time to detect the physical state based on various information input in the processes of steps 100, 110, 120 and the like described above. For example, it is determined whether or not it is the timing for detecting the physical state based on whether or not all of the determination conditions 1, 2, and 3 are satisfied. If a negative determination is made here, the process returns to step 100, whereas if an affirmative determination is made, the process proceeds to step 140.

  In step 140, since the timing for detecting the body state has been reached, the body state is detected by the body state detection sensor 1 or the like. For example, as described later, the heart rate is measured using the electrocardiographic sensor 1a.

  In subsequent step 150, it is determined whether or not the detected data is appropriate data. That is, it is difficult to obtain appropriate data due to a measurement error or the like, and therefore it is determined here whether or not the obtained data is appropriate data. If an affirmative determination is made here, the process proceeds to step 160, whereas if a negative determination is made, the process returns to step 140. If appropriate data cannot be obtained even after repeating the measurement a predetermined number of times, it is determined that there is no data this time, the process of step 150 is passed, and the process proceeds to step 160.

  In subsequent step 160, the obtained detection results and measurement conditions are stored in the memory (EEPROM 3d). In addition, as measurement conditions, environmental temperature (vehicle interior temperature) etc. are mentioned, for example.

  In the subsequent step 170, data of detection results stored in the memory are collected. Specifically, for example, when data is accumulated every day, data before a certain period (for example, data before one month) is averaged and stored in units of one month.

In the subsequent step 180, the data is displayed on the monitor 5, and the present process is temporarily terminated. The data display method can be appropriately selected manually.
c) Next, the details of processing in each of the above steps will be described in detail together with the devices used.

(1) The body information detected in step 140 includes at least one of body temperature, blood pressure, heart rate, pulse wave information, body weight, blood sugar level, and body fat.
The body temperature can be detected using a non-contact thermosensor (temperature sensor 1) using infrared rays.

  Blood pressure is estimated by PWV (pulse wave velocity) and pulse wave sensor. The PWV can be obtained from the propagation speed of the pulse wave using the electrocardiographic sensor 1a and the pulse wave sensor 1b (mounted on an arm, a finger or the like).

The heart rate can be obtained by the electrocardiographic sensor 1a or the pulse wave sensor 1b.
The pulse wave information (pulse rate, blood vessel age, etc.) can be obtained by the pulse wave sensor 1b.
The weight can be obtained by the sheet sensor 1d or the like.

The blood sugar level can be automatically obtained from a blood sample collected by a slight puncture of a finger or the like.
The body fat can be obtained by, for example, a body fat scale (not shown) connected to the pair of electrodes 17a and 17b attached to the steering wheel 15.

  (2) The timing judgment condition in step 130 includes at least one of time, time since boarding, time since stopping, heart rate, vehicle behavior, vehicle interior temperature, and navigation information. Can be adopted. The accuracy of information is improved by combining as many conditions as possible.

-For example, by measuring within a predetermined time in the morning, the influence of circadian rhythm can be reduced.
In addition, measuring physical information in different time zones and storing a plurality of detection results has the effect of improving the reliability of data processing, but among them, it is more preferable to rank the preferred timing. Data obtained at the timing may be stored as data of the day. For example, when all data is obtained by measurement in the morning, noon, and night (when the preferred timing is morning>day> night), the most preferable morning data is stored as the data of the day. If only day and night data can be obtained, the more preferable day data is stored as the day data. Further, when there are a plurality of optimum morning data, the average value of the data is stored as optimum data.

  For example, when the time after getting on (obtained from the seat sensor 1d) exceeds a predetermined time (for example, 3 minutes) after getting on, or the time after stopping (obtained from the vehicle speed sensor 1a) is the predetermined time When it becomes more than (for example, 3 minutes), by detecting physical information, a physical state can be detected in a state close to a resting state.

For example, when the change in the heart rate per unit time (for example, 1 minute) is 5% or less, measurement in a stable state is possible by detecting the body condition.
For example, when vehicle behavior such as acceleration / deceleration or turning of the vehicle (obtained from the acceleration sensor 1b) is small below a predetermined value or when the vehicle speed (obtained from the vehicle speed sensor 1a) is low below a predetermined value, By detecting the state, measurement in a stable state becomes possible.

For example, when the change in the passenger compartment temperature is as small as 1 ° C. or less per minute, the measurement in a stable state is possible by detecting the body condition.
-For example, by obtaining navigation information such as when leaving a house or company or traveling on a highway, measurement under the same conditions becomes possible, so the reliability of physical information is improved.

  (3) When there are multiple measurement timings (when conditions are set gently), the timing for determining which timing is optimal is at least one of time, navigation information, vehicle behavior, heart rate, and vehicle interior temperature. Can be adopted. Therefore, when a plurality of pieces of physical information are obtained under moderate conditions, it is desirable to adopt information at the optimal timing.

For example, in the case of navigation information, when it is close to the house or when the road is thick, it can be regarded as optimal compared to the case where it is not.
For example, in the case of vehicle behavior, it can be regarded as optimal in the order of stoppage> during constant speed> acceleration / deceleration or turning.

For example, when the heart rate and the passenger compartment temperature are within a predetermined fluctuation range, they can be regarded as optimum compared to the case where the heart rate and the passenger compartment temperature are not.
Here, it is preferable that the condition for determining that the timing is optimal is matched with the timing that was previously optimized (from the measurement result).

  When navigation information is used, the navigation information is distinguished by some attributes. For example, it is classified into at least two types of attributes among home, workplace, shopping center, restaurant, gym, highway, main road, urban area, hospital, and user setting place. As a result, it is possible to know the physical information in which attribute, so that it is easy to understand the meaning of the physical information and the reliability is improved.

  (4) When displaying the measurement result on the monitor 5 etc., it is necessary, for example, by selecting at least two periods of 1 day, 1 week, 1 month, 6 months, 1 year, 5 years, and 10 years. It is preferable because the measurement result according to the above becomes easy to see.

  At this time, the physical information is collectively stored or displayed according to the time or period when the physical information is obtained. As a method for aggregating the physical information, at least one of a day of the week, a difference from an average value, time, navigation information, vehicle behavior, heart rate, and vehicle interior temperature can be employed.

In the case of aggregation by day of the week, it can be considered that the situation is the same, for example, a method of aggregating (e.g., averaging) data from Monday to Friday.
In the case of aggregation based on the difference from the average value, if the difference is larger than the predetermined value, it is excluded as an abnormal value and is aggregated (for example, averaged) only with data within the predetermined value.

In the case of aggregation by time, it can be considered the same situation, for example, a method of aggregating (for example, averaging) morning data.
In the case of aggregating with navigation information, for example, a method of aggregating (for example, averaging) data in a similar place or a similar type of road is considered.

In the case of aggregation by vehicle behavior, a method of consolidating (for example, averaging) data that is considered to be the same situation, for example, data at a constant speed is conceivable.
-When collecting by heart rate, it is considered that the situation is the same in each state when stopping and driving, so for example, data during driving with a high heart rate is cut and the remaining data is aggregated (for example, Method).

In the case of aggregation by the passenger compartment temperature, a method of aggregating (for example, averaging) data in a predetermined temperature range considered to be the same situation can be considered.
In other words, for example, when the physical information is obtained at an old age such as before one year or when the period is a long span such as one year, if all the physical information is stored, the data storage area becomes large. The burden of data processing increases. In such a case, for example, if the data is summarized and stored like average data every month, old data or data over a long period of time can be stored in a good manner.

  Therefore, for example, as shown in FIG. 5A, when displaying for one week, daily data of blood pressure, heart rate, and weight can be displayed. In addition, when the display is switched manually with a switch or the like annually, an average value for each month can be displayed as shown in FIG.

(5) When storing or displaying physical information, it is desirable to simultaneously store or display data indicating the amount of daily activity.
Note that the data indicating the amount of daily activity is at least one of navigation information, information from an acceleration sensor (acceleration sensor (not shown) attached to the body, not the acceleration sensor 9b mounted on the vehicle), schedule, and sleep information. Can adopt seeds.

For example, when the daily activity amount is known by an acceleration sensor or schedule worn on the body, the data is also stored or displayed.
As a result, for example, when the blood pressure is displayed at a high level, it can be understood if it is a period in which the amount of activity is high, but if it is a period in which the amount of activity is low, it can be estimated that there is a cause in the body Is possible.

(6) It is desirable to correct the physical information obtained in the passenger compartment by the physical information obtained outside the passenger compartment.
For example, heart rate and blood pressure data while riding in the vehicle may differ from the data detected during rest, so that data during boarding is corrected using the data during rest. For example, correction is performed to reduce the heart rate and blood pressure by a predetermined ratio. Thereby, it is possible to grasp the true state of the body using data on boarding the vehicle.

Note that the detection target of the physical information may be not only the driver but also another passenger.
Moreover, since the timing determination conditions can be changed manually, more accurate physical information can be obtained.

d) Next, experimental data according to this example will be described.
(1) FIG. 6 is a graph showing time changes between the systolic blood pressure (SBP) and the heart rate (HR) after exercise.

  FIG. 6 shows that when the heart rate decreases, the blood pressure also decreases. It can also be seen that when the change in heart rate is within about 5%, the blood pressure is also almost constant. In other words, if you look at changes in heart rate, you can also predict changes in blood pressure, so if you have little fluctuation in heart rate, you can measure in a more resting state by detecting your physical condition. is there.

(2) FIG. 7 shows the time change of the systolic blood pressure (SBP) when the temperature (TEMP) changes.
FIG. 7 shows that the blood pressure increases when the temperature is low. That is, it can be seen that there is a correlation between a change in temperature and a change in blood pressure. Therefore, when the body condition is detected when the temperature change is small, the measurement can be performed in a more quiet state.

(3) FIG. 8 shows the time change of the heart rate (HR) when the temperature (TEMP) changes.
It can be seen from FIG. 8 that the heart rate does not become a constant value when the temperature change is severe. Therefore, from this point as well, if the body state is detected when the temperature change is small, measurement in a more resting state is possible.

  (4) FIG. 9 shows the relationship between the vehicle speed and the blood pressure equivalent value (pulse wave propagation time PTT). The pulse wave propagation time PTT is the reciprocal of the pulse wave propagation speed PWV, and the longer the pulse wave propagation time PTT, the lower the blood pressure.

  From FIG. 9, it can be seen that there is a correlation between the vehicle speed and the blood pressure. This is presumed to be because G due to acceleration / deceleration moved the blood flow inside the human body and consequently changed the blood pressure at the measurement site. This means that when there is a change in the vehicle speed, a biological quantity such as blood pressure cannot be stably measured due to a change in acceleration / deceleration G. Therefore, if the body state is detected while the vehicle is stopped or traveling at a constant speed, measurement in a more quiet state is possible.

  (5) FIG. 10 shows the changes in the amount of living body according to time (morning and afternoon), specifically, changes in heart rate HR, systolic blood pressure SBP, and diastolic blood pressure DBP. The maximum blood pressure SBP and the minimum blood pressure DBP were directly measured with a sphygmomanometer.

  From FIG. 10, it can be seen that the amount of variation of each living body amount is different between morning and afternoon. Therefore, it is desirable to change the measurement time depending on which body mass is used as which body information.

For example, the heart rate HR has a small amount of fluctuation when measured in the morning, but the systolic blood pressure SBP and the diastolic blood pressure DBP do not change so much in the morning or in the afternoon.
As described above in detail, in this embodiment, the timing suitable for the detection of the body condition (the state that is less affected by the disturbance and is as quiet as possible) is determined, and the body condition is detected at that timing. There is an effect that the variation in physical information necessary for the measurement is small and the accuracy is high.

  Next, the second embodiment will be described, but the description of the same contents as the first embodiment will be omitted. In this embodiment, the hardware configuration is the same as that of the first embodiment, but the control contents are different. Therefore, the control contents will be described.

The present embodiment performs processing for constantly detecting the physical state of the person on board the vehicle and storing the physical information as the detection result at an appropriate timing.
As shown in the flowchart of FIG. 11, when the ignition key is turned on, in step 200, the body state is constantly (periodically) measured by the body state detection sensor 1 and the body information is obtained.

In the subsequent step 210, the measurement necessary for the determination of the storage timing is started by the device (sensor or the like) used for the determination of the physical state detection timing similar to that in the first embodiment.
In the following step 220, the vehicle behavior is confirmed. Specifically, information from a vehicle control sensor 9 such as a vehicle speed sensor 9a or an acceleration sensor 9b is input, and various vehicle behaviors such as stopping, running at a constant speed, acceleration / deceleration, and turning are confirmed.

  In subsequent step 230, the navigation information is confirmed. Specifically, based on information from the navigation device 13, the current travel position, what kind of road the vehicle is traveling, and the like are confirmed.

  In the following step 240, it is determined whether or not it is time to store the detected physical information based on various information input in the above-described steps 210, 220, and 230. If a negative determination is made here, the process returns to step 200. If an affirmative determination is made, the process proceeds to step 250.

  In step 250, it is determined whether the detected data is appropriate data. If an affirmative determination is made here, the process proceeds to step 260, while if a negative determination is made, the process returns to step 200. If proper data cannot be obtained even after repeating the measurement a predetermined number of times, it is determined that there is no data this time, the process of step 250 is passed, and the process proceeds to step 260.

In subsequent step 260, the physical information and measurement conditions at the timing of storage are stored in the memory (EEPROM 3d).
In the subsequent step 270, data of detection results stored in the memory are collected.

In the subsequent step 280, the data is displayed on the monitor 5, and the present process is temporarily terminated.
As described above in detail, in this embodiment, the body state is constantly detected, and the timing suitable for the storage of the body state (the state that is less affected by the disturbance and is as quiet as possible) is determined. Therefore, only physical information with little variation and high accuracy necessary for health management can be selected and stored.

  Next, the third embodiment will be described, but the description of the same contents as the first embodiment will be omitted. In this embodiment, the hardware configuration is the same as that of the first embodiment, but the control contents are different. Therefore, the control contents will be described.

In this embodiment, when the timing for detecting the body condition is reached, the driver is notified of this.
As shown in the flowchart of FIG. 12, in step 300, measurement necessary for timing determination is started by a device (such as a sensor) used for determining the timing of detection of the body state.

In the subsequent step 310, the vehicle behavior is confirmed.
In the following step 320, the navigation information is confirmed.
In the subsequent step 330, it is determined whether or not it is time to detect the body state based on various information input in the processes of steps 300, 310, 320 and the like described above. If a negative determination is made here, the process returns to step 300. If an affirmative determination is made, the process proceeds to step 340.

In step 340, since the timing for detecting the physical state has been reached, this is displayed on the monitor 5 or notified by voice or the like using the speaker 7.
In step 350, it is determined by the notification whether or not the driver or the like has made an input to detect the physical state by a switch operation (for example, the touch panel of the monitor 5). If an affirmative determination is made here, the process proceeds to step 360. If a negative determination is made, the process returns to step 340.

In step 360, since there is an input for detecting the body state, the body state is detected by the body state detection sensor 1 or the like.
In the subsequent step 370, it is determined whether or not the detected data is appropriate data. If an affirmative determination is made here, the process proceeds to step 380. If a negative determination is made, the process returns to step 370. If appropriate data cannot be obtained even after repeating the measurement a predetermined number of times, it is assumed that there is no data at this time, the process of step 370 is passed, and the process proceeds to step 380.

In the subsequent step 380, the obtained detection results and measurement conditions are stored in the memory (EEPROM 3d).
In the subsequent step 390, the detection result data stored in the memory is collected.

In the subsequent step 395, the data is displayed on the monitor 5, and the present process is temporarily terminated.
In this way, in this embodiment, when the timing for detecting the physical condition is reached, the driver is notified to that effect, so the driver who has received the notification manually detects the physical condition. Can be directed. Therefore, since the body state is detected only when necessary, there is an advantage that the processing load is small.

  In addition, as in Example 2, when physical information is always detected and the timing of storage is reached, that fact is notified, and when instructed manually, the physical information (at that timing) is You may make it memorize | store.

  Next, the fourth embodiment will be described, but the description of the same contents as the first embodiment will be omitted. In this embodiment, the hardware configuration is the same as that of the first embodiment, but the control contents are different. Therefore, the control contents will be described.

In this embodiment, physical information is compared with physical information for a predetermined period in the past (which is a reference), and the vehicle is controlled based on the comparison result.
As shown in the flowchart of FIG. 13, in step 400, body information is obtained by detecting the body state at the detection timing described above.

In subsequent step 410, the physical information detected this time is compared with physical information (for example, an average value thereof) for a predetermined period as a past reference.
In subsequent step 420, as a result of the comparison, it is determined whether or not the current physical information is abnormal compared to the past physical information. For example, it is determined whether or not the blood pressure is abnormally high. If it is determined that there is an abnormality, the process proceeds to step 430. If a negative determination is made, the process is temporarily terminated. In step 430, the driver or the like is notified by the monitor 5, the speaker 7 or the like that there is an abnormality.

  In the following step 440, since it is considered that the driver's physical condition is abnormal, the vehicle is controlled to the safe side. For example, control such as a reduction in speed or an increase in braking performance is performed, and the present process is temporarily terminated.

  As described above, in this embodiment, when the physical information obtained during boarding of the vehicle is abnormal as compared with the past physical information, the vehicle is controlled to the safe side, so that the safety is improved. There is.
