  In this type of physical condition determination device, the acquired biological information itself or the determination result of the physical condition of the driver is transmitted to an information processing apparatus installed in a medical institution, and the acquired biological information and physical condition are acquired in the vehicle. There has been proposed a method for using the determination result in medical practice.

  Thus, in the physical condition determination device for using the determination result of the biological information and the physical condition acquired in the vehicle for the medical practice, as the timing of acquiring the biological information, until the driving is started after the driver is seated. For example, during the period (for example, see Patent Document 2) or during traveling on a commuting route (for example, see Patent Document 3).

JP 2004-242945 A JP 2005-168908 A JP 2006-302206 A

  For this reason, the biological information collected by the information processing apparatus installed in the medical institution from the conventional physical condition determination apparatus is acquired only at a predetermined timing. As a result, medical personnel such as doctors can grasp the timing at which the biometric information is acquired as one of the situations when the biometric information is acquired, but, for example, are taking drugs before driving The user's behavior such as the possibility and the possibility of exercising before driving could not be grasped.

  Therefore, even if the biological information acquired by the conventional physical condition determination device is unclear in the situation other than the acquired timing and is collected in the information processing device installed in the medical institution, the collected biological information There has been a problem that it is difficult to accurately perform medical practice based on information and the like.

That is, in the conventional physical condition determination device, there is a problem that information according to the situation of each user is not acquired.
SUMMARY OF THE INVENTION An object of the present invention is to obtain information according to the situation of each user and execute control in an apparatus mounted on a vehicle.

The present invention is a vehicle control device.
In other words, the invention device for controlling the running state of the vehicle is generated by a medical institution in which a vehicle occupant has undergone a medical practice as a patient, and information related to the medical practice is medical information, and the medical information is medical information acquisition means. Is acquired, at least based on the acquired medical information, the vehicle control means determines whether or not the steering influence that is likely to affect the steering of the vehicle is greater than or equal to a preset set value. If the steering influence is greater than or equal to the set value, the vehicle is controlled so as to reduce the danger during traveling.

Therefore, in the invention device, if the steering influence based on the medical information generated for each occupant is greater than or equal to the set value, the vehicle is controlled so that the danger during traveling is reduced.
Thereby, in the vehicle control apparatus of this invention, control of the vehicle according to each passenger | crew's condition can be performed. In particular, according to the vehicle control device of the present invention, when the occupant is sick, such as when the occupant undergoes medical practice at a medical institution, the danger is further reduced compared to when the occupant is in a healthy state, That is, the vehicle can be driven more safely.

  By the way, for example, when a vehicle occupant receives an infusion at a medical institution, it can be said that the vehicle occupant is in a poor physical condition that needs to receive an infusion. In such a case, the occupant is more likely to have a reduced judgment ability or the like necessary for running the vehicle compared to when the occupant's physical condition is normal (i.e., good), compared to during normal driving. Therefore, it is required to drive the vehicle more safely.

  For this reason, the vehicle control means in the present invention includes information on a plurality of items, and the medical information acquired by the medical information acquisition means has a strong influence on the treatment that may affect the operation of the vehicle. It is configured to analyze whether or not force treatment information is included, and if the result of the analysis includes strong influence treatment information, the steering influence is assumed to be greater than or equal to the set value. desirable.

  It should be noted that the high-impact treatment information here refers to vehicle operation, such as having received an infusion at a medical institution, or having been examined by a medical institution when the physical condition is significantly worse than at the time of normal physical condition. This includes that a medical institution has made a diagnosis (diagnosis) that may have an impact.

  In addition, for example, when an occupant is instructed to take a drug that is likely to decrease arousal as a side effect (hereinafter referred to as a major side effect drug) and immediately before driving the vehicle, When taken inside, the occupant may be less awake while driving the vehicle, and is required to drive the vehicle more safely than during normal driving.

  For this reason, in the apparatus of the present invention, the biological information generation means generates biological information representing the state of the occupant based on the biological signal detected from the occupant of the vehicle at a predetermined interval, and the generated biological The biological information accumulation control unit accumulates information in the storage unit. In the vehicle control means, the change amount deriving means derives the change amount of the biological information from the biological information stored in the storage unit and generated at different timings, and the treatment execution determining means derives the change amount. By determining whether or not the amount of change derived by the means is greater than or equal to the reference fluctuation amount of the biological information that should be changed when a treatment that may affect vehicle operation is performed, It is desirable to determine whether or not the treatment has been executed, and when the strong influence treatment is executed as a result of the determination, it is desirable that the steering influence be greater than or equal to a set value.

  By the way, even if the occupant takes a major side-effect drug, the wakefulness of the occupant may not decrease while the vehicle is driving, and if the wakefulness does not decrease, the vehicle is controlled so that the risk is reduced May interfere with traffic.

  For this reason, the vehicle control device estimates the steering influence force of the occupant who is actually driving the vehicle, and controls the vehicle to reduce the danger when the estimated steering influence force is greater than or equal to the set value. It is desirable to be configured to do so.

  However, even with the vehicle control device configured as described above, when the occupant takes a major side-effect drug, it is required to more reliably reduce the danger during traveling of the vehicle. For this reason, when an occupant takes a major side-effect drug, it is desirable that the steering influence of the occupant who is driving the vehicle is estimated as having a lower arousal level than during normal driving.

  That is, in the vehicle control means according to the present invention, the situation estimation means estimates the steering influence by determining whether or not the biological information generated by the biological information generation means is greater than or equal to the set determination threshold. Then, the threshold setting means determines whether or not the strong influence therapy has been executed by determining whether or not the change amount is equal to or greater than the reference variation amount. It is desirable that the determination threshold is set so that the steering influence is larger when the influence treatment is executed, compared to the steering influence when the strong influence treatment is not executed. .

  The high-impact treatment mentioned here refers to drugs that may affect vehicle operation, such as drugs that are likely to reduce arousal as a side effect or drugs that are likely to cause anemia as a side effect. Including being instructed to take.

  Note that the biological information in the present invention may be at least one of an occupant's eye movement, blink, heart rate variability, blood pressure, pulse wave, face image, and pulse wave propagation time.

It is configured to determine the physical condition of the driver by comparing the physical condition determination threshold based on the physical condition determination threshold.
<Biological information generation process>
Next, the process procedure of the biometric information generation process which CPU13 performs is demonstrated.

Here, FIG. 4 is a flowchart showing a processing procedure of the biometric information generation processing in the first embodiment.
This biometric information generation process is started at each predetermined start timing when the internal combustion engine of the host vehicle is started (in this embodiment, an ignition signal is input).

  When the biometric information generation process is started, as shown in FIG. 4, first, in S110, it is determined whether or not behavior information has been acquired from the navigation device 30, and if it has not been acquired as a result of the determination. The process waits until the action information is acquired. When the action information is acquired, the process proceeds to S120.

  In S120, it is determined whether or not the medical information has been acquired, that is, whether or not the medical information has been acquired when the biometric information generation process was executed before the previous time. If has not been acquired, the process proceeds to S130.

In S130, the process waits until medical information is acquired. When the medical information is acquired, the medical information is stored in the RAM 12 or the storage device 16, and the process proceeds to S140.
Specifically, in the present embodiment, if the medical information storage medium embedded in the examination ticket is an IC tag, the medical information is acquired when the medical information storage medium exists within the communication range of the data reader, If the medical information storage medium is a flash EEPROM, medical information is acquired when the medical information storage medium is attached to the data reader 17.

In S140, measurement timing (measurement timing) for measuring a biological signal is set based on the scheduled treatment time included in the medical information.
Specifically, in the present embodiment, the measurement interval is set as a predetermined interval (that is, an initial value), and the measurement interval within a certain time before and after the scheduled treatment time is set as an interval shorter than the specified interval. Set the timing. Furthermore, if the medical appointment information includes the appointment appointment date and time, the measurement timing is such that the closer the appointment appointment date is, the shorter the measurement interval is, that is, the closer the appointment appointment date is, the more the number of measurements is increased. Set. However, the measurement interval is set longer than the activation timing interval.

In S150, the physical condition determination threshold is changed from the initial value stored in the ROM 11 to the physical condition determination threshold included in the medical information, and the process proceeds to S160.
In S160, the current time is acquired from the timing device, and it is determined whether or not the acquired current time is the measurement timing set in S140. If the result of determination is not the measurement timing, the measurement timing is reached. Until the measurement timing is reached, the process proceeds to S170.

  In S170, all types of biological signals preset as measurement targets are measured, and the process proceeds to S180. Specifically, in the present embodiment, at least three of an electrocardiogram signal, a pulse wave signal, and a skin temperature (that is, body temperature) are measured as biological signals.

  In S180, it is determined whether all types of biological signals have been measured. If all types of biological signals are not measured as a result of the determination, the process returns to S170 until all types of biological signals are measured. When the measurement of the biological signal is repeated and all the biological signals are measured, the process proceeds to S190. In the present embodiment, as a case where an electrocardiogram signal or a pulse wave signal is not measured, for example, a case where the driver releases one hand from the steering wheel S and operates the shift lever of the host vehicle may be considered.

  Further, in S190, blood pressure and heart rate generated by analyzing each of the biological signals measured in S170 and the electrocardiogram signal and pulse wave signal measured in S170 by a well-known method are generated as biological information. The process proceeds to S200. In S200, the information is stored in the storage device 16 in association with the time when the biometric information is generated in S190, and the process proceeds to S210.

  In S210, the difference between each biometric information generated in the biometric information generation process activated this time and each biometric information generated in the biometric information generation process activated last time is calculated as a biometric information change amount. To do.

  Subsequently, in S220, the driver's physical condition is determined by comparing each of the biological information change amounts calculated in S210 with each of the physical condition determination threshold values set in S150. As a result of the determination, the physical condition of the driver is determined. If not, the process proceeds to S230.

  In the present embodiment, specifically, when the difference between one biological information change amount and the physical condition determination threshold is greater than or equal to a predefined value, or when there is a predefined amount of biological information variation or more. When the physical condition is determined to be worse than the physical condition determination threshold, it is determined that the driver's physical condition is poor. Further, for example, as shown in FIG. 7A, when determining the physical condition of the driver using the heart rate in the biological information, the physical condition is determined when the heart rate becomes equal to or higher than the physical condition determination threshold. May be judged to be bad.

In S230, emergency information indicating that the driver's physical condition is bad is transmitted to the medical institution setting device group 60 via the communication device 18, and the process proceeds to S240.
On the other hand, as a result of the determination in S220, if it is determined that the driver's physical condition is not bad (here, the physical condition is good, or it is the same as normal (ie, normal)), S230 is executed. Without proceeding, the process proceeds to S240.

  Then, in S240, a command is output to the navigation device 30 so that the determination result in S220 is displayed on the display unit 33 and further output from the voice output unit 35 by voice. Thereby, the result of physical condition determination is notified in the own vehicle via the display part 33 and the audio | voice output part 35. FIG.

  In subsequent S250, based on the behavior information acquired from the navigation device 30, a behavior burden degree representing a burden on the driver is calculated. For example, in the present embodiment, when the behavior information acquired from the navigation device 30 indicates that the host vehicle is traveling, the period during which the host vehicle is traveling and the body during the driving of the host vehicle. The product of the burden coefficient representing the burden on the vehicle and the stress coefficient representing the stress during driving of the host vehicle is derived as the degree of action burden.

  Note that the burden coefficient and the stress coefficient are set in advance for each activity content and stored in the storage device 16 by an inquiry conducted by the medical staff to the driver as one of the medical actions. For example, if it is a stress factor, the activity content is work in the company, exercise in the gym, and driving the vehicle, and if it is a burden factor, the activity content is exercise in the gym, driving the vehicle, company It is set so that it becomes small in order of the work in.

  In S260, the action burden derived in S250 is displayed on the display unit 33, and a command is output to the navigation device 30 so as to be output from the audio output unit 35 by voice. Thereby, the degree of action burden is notified in the own vehicle via the display unit 33 and the audio output unit 35.

  Subsequently, in S270, it is determined whether or not the treatment content in the medical information has been executed by comparing the biometric information change amount calculated in S210 with the set threshold value included in the medical information (hereinafter referred to as treatment execution determination). If the result of determination is that treatment content has not been executed, the process proceeds to S280.

  For example, when the antihypertensive medication is set as the treatment content and the antihypertensive medication scheduled time is set as the scheduled treatment time, the scheduled medication time elapses as shown in FIG. If the biometric information (that is, blood pressure) generated over a predetermined number of times continues to rise (that is, if the biometric information change amount has not decreased by a predetermined value or more than the set threshold), the antihypertensive agent It may be determined that the medicine is not taken (that is, treatment content is not executed).

  In S280, treatment guidance indicating that the content of treatment is urged to be executed is notified in the own vehicle, and the process proceeds to S290. In other words, the treatment guidance and the scheduled treatment time are displayed on the display unit 33, and further, a command is output to the control unit 36 of the navigation device 30 so as to be output from the audio output unit 35 by voice.

On the other hand, if the treatment content in the medical information is executed as a result of the treatment execution determination in S270, the process proceeds to S290 without executing S280.
In S290, each of the biological information generated in S190 of the current cycle, the determination result of the driver's physical condition in S220 (hereinafter referred to as physical condition determination result), the behavior burden calculated in S250, and S270 The determination result of whether or not the treatment content in (1) is executed (hereinafter referred to as the treatment determination result) is set as transmission information, and the process proceeds to S300.

In S300, the transmission information set in S290 is transmitted to the medical institution installation device group 60 via the communication device 18.
Thereafter, the biometric information generation process is terminated, and the process waits for the next activation timing.

  As a result of the determination in S120, if the medical information has been acquired before the previous cycle, the process proceeds to S310, and the advice information output from the medical institution installation device group 60 is acquired in S310. It is determined whether or not.

  The advice information referred to here is a warning or advice given to a driver by a medical person based on transmission information from the in-vehicle device 5. This information is generated as one and transmitted via the communication device 65.

  If the advice information is acquired as a result of the determination in S310, the process proceeds to S320, and the advice information is notified in the own vehicle in S320. That is, the advice information is displayed on the display unit 33, and further, a command is output to the control unit 36 of the navigation device 30 so that the voice output unit 35 outputs the voice information.

Thereafter, the process proceeds to S160.
On the other hand, if the advice information is not acquired as a result of the determination in S310, the process proceeds to S160 without executing S320.

That is, in the biological information generation process of the present embodiment, the measurement timing based on the medical information generated by the medical institution for each driver is set, and the biological information is generated according to the biological signal measured at the measurement timing, Based on the generated biometric information, it is determined whether the driver's physical condition and whether the driver has executed the treatment content. Then, the behavior burden level is calculated based on the driver's behavior, and further, the medical institution installation apparatus group 60 uses the biological information, the physical condition determination result, the treatment execution determination result, and the behavior burden level as transmission information. Send to.
[Effect of the first embodiment]
As described above, according to the in-vehicle device 5 of the present embodiment, the measurement timing based on the medical information generated for each driver is set, so that the biometric information desired by the medical staff is set in each passenger's situation. Can be generated accordingly. And according to the vehicle-mounted apparatus 5 of this embodiment, in order to transmit the produced | generated biological information to the medical institution installation apparatus group 60, the medical institution installation apparatus group 60 can collect the biometric information which a medical person wants, By reflecting the collected biological information in the medical practice, the accuracy of the medical practice (for example, a medical examination or the like) can be improved.

  In particular, according to the biometric information generation process of the present embodiment, medical personnel analyze the biometric information collected in the medical institution installation device group 60 in order to set the measurement timing based on the scheduled treatment time in the medical information. Thus, the effect of the treatment content can be verified and reflected in the subsequent medical practice. In other words, medical personnel can confirm the effects of drugs taken, such as antihypertensive agents, and the effects of infusions administered at medical institutions.

  Further, in the biometric information generation process of the present embodiment, the physical condition of the driver is determined by comparing each biometric information change amount and each physical condition determination threshold value in the medical information. For this reason, according to the biometric information generation process of the present embodiment, when the driver is immediately after receiving a diagnosis at a medical institution, an appropriate physical condition is determined in accordance with the physical condition of the occupant at that time. it can.

  Furthermore, according to the biological information generation process of the present embodiment, the result of the physical condition determination is notified in the own vehicle, so that the vehicle occupant can recognize the physical condition of the driver and drive the vehicle more safely. Can be made.

  Further, in the biometric information generation process of the present embodiment, the treatment execution determination is performed by comparing the biometric information change amount and the setting threshold included in the medical information, and the driver does not execute the treatment content. A notification to the effect that the treatment content is to be executed is given in the own vehicle. For this reason, according to the biometric information generation process of the present embodiment, the driver can be made to execute the treatment content more reliably, and the health of the driver can be maintained.

  Furthermore, according to the biometric information generation process of the present embodiment, the behavior burden level is derived based on the driver's behavior information, and the behavior burden level is notified to the own vehicle. Can suppress the driver's excessive activity.

  By the way, according to the biometric information generation process of the present embodiment, in addition to the biometric information, the physical condition determination result, the treatment execution determination result, and the action burden level are transmitted to the medical institution installation apparatus group 60. As a judgment material when performing an action, the result of physical condition determination, the result of treatment execution determination, and the action burden level can be used. That is, according to the biometric information generation process of the present embodiment, it is possible to increase the determination material when performing a medical practice, and it is possible to further improve the accuracy of the medical practice.

In addition, according to the biometric information generation process of the present embodiment, as the scheduled medical checkup date is closer, more biometric information is generated, so that it is possible to increase the judgment materials for medical personnel.
In particular, according to the biometric information generation process of the present embodiment, the behavior burden degree is derived by quantification, so that medical personnel can easily recognize it. Furthermore, according to the biological information generation process of the present embodiment, the behavior burden is calculated using each of the burden coefficient and the stress coefficient, so that the stress applied to the occupant and the load applied to the occupant's body can be derived. When a medical person performs medical practice, the medical person can be made aware of the state of the driver from both physical and mental aspects.

Furthermore, in the biological information management system 1 of the present embodiment, the in-vehicle device 5 acquires the result of medical practice (ie, advice information) based on the biological information collected in the medical institution installation device group 60, and the inside of the own vehicle. To inform. For this reason, according to the biological information management system 1 of the present embodiment, it is possible to make the occupant of the host vehicle recognize the more accurate state of the driver at the present time, and as a result, the vehicle is driven more safely. Can be made.
[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  The biological information management system of the present embodiment and the biological information management system 1 of the first embodiment differ only in the processing program stored in the ROM 11 of the control device 10 and the processing executed by the CPU 13. For this reason, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and description will be made focusing on processing different from that in the first embodiment.

  The control device 10 according to the present embodiment is configured around a known microcomputer including at least a ROM 11, a RAM 12, a CPU 13, and a bus connecting them.

Among these, the ROM 11 estimates the driver's activity content based on the action information acquired from the navigation device 30, detects the biological signal from the driver before and after the activity content, and generates the biological information. The CPU 13 performs a biometric information generation process for deriving a burden on the driver in the activity contents (hereinafter referred to as an activity burden level) and transmitting the biometric information and the activity burden level to the medical institution setting device group 60. Stores a processing program to be executed.
<Biological information generation process>
Next, the process procedure of the biometric information generation process which CPU13 performs is demonstrated.

Here, FIG. 5 is a flowchart showing a processing procedure of the biometric information generation processing in the second embodiment.
This biological information generation process is started when the internal combustion engine of the host vehicle is started (in this embodiment, an ignition signal is input).

  When the biometric information generation process is started, as shown in FIG. 5, first, in S410, it is determined whether or not biometric information has been acquired at a first timing described later. If the biological information is not acquired at the first timing, the process proceeds to S420.

  In S420, it is determined whether or not the behavior information has been acquired from the navigation device 30, and if not acquired as a result of the determination, the process waits until the behavior information is acquired. If the behavior information is acquired, the process proceeds to S430.

  In continuing S430, based on the action information acquired by S420, the activity content which a driver is going to perform is estimated. Specifically, in the present embodiment, if the destination facility data included in the behavior information is an exercise facility such as a gym, the activity content is exercise, and the destination facility data is a restaurant or other eating and drinking facility. For example, it is estimated that a meal is scheduled to be executed as the activity content.

  In step S440, a predetermined time before the activity content estimated in step S430 is set as the first timing, and a predetermined time after execution of the activity content is set as the second timing. Specifically, in the present embodiment, the first timing is a specified time before arrival at the destination (for example, 10 minutes before arrival at the eating and drinking facility), and a predetermined time after the departure from the destination (for example, the eating and drinking facility). 10 minutes after departure) is set as the second timing.

  Subsequently, in S450, the current time is acquired from the timing device, and it is determined whether or not the acquired current time is the first timing set in S440. The system waits until one timing is reached, and proceeds to S460 when the first timing is reached.

  In S460, all types of biological signals preset as measurement targets are measured, and the process proceeds to S470. Specifically, in the present embodiment, at least three of an electrocardiogram signal, a pulse wave signal, and a blood glucose level are measured as biological signals.

  In S470, it is determined whether all types of biological signals are measured. If all types of biological signals are not measured as a result of the determination, the process returns to S460 until all types of biological signals are measured. When the measurement of the biological signal is repeated and all the biological signals are measured, the process proceeds to S480. In the present embodiment, as a case where the biological signal is not measured, for example, it is conceivable that the driver moves one hand from the steering wheel S and operates the shift lever of the own vehicle.

  Furthermore, in S480, blood pressure, heart rate, etc. generated by analyzing each of the biological signals measured in S450 and both the electrocardiogram signal and pulse wave signal measured in S450 by a known method are used as biological information. The biometric information is stored in the storage device 16 in association with the acquired time (hereinafter referred to as first biometric information), and the process proceeds to S490.

In S490, the current time is acquired from the timing device, and it is determined whether or not the acquired current time is the second timing set in S440.
However, if the activity content is an exercise at an exercise facility or a meal at an eating and drinking facility, the host vehicle is parked before the second timing after the biological information is stored in the storage device 16 at S480. (That is, the internal combustion engine of the host vehicle is stopped), and the biometric information generation process is terminated. Then, when the activity content is finished, an ignition signal is input again, and this biometric information generation process is started, it is determined in S410 that biometric information has been acquired at the first timing, The biometric information generation process is restarted from S490.

If the result of determination in S490 is not the second timing, the process waits until the second timing is reached, and if the second timing is reached, the process proceeds to S500.
In S500, all types of biological signals preset as measurement targets are measured, and the process proceeds to S510. In S510, it is determined whether all types of biological signals have been measured. If all types of biological signals are not measured as a result of the determination, the process returns to S500, and the measurement of the biological signals is repeated until all types of biological signals are measured. The process proceeds to S520.

  In S520, blood pressure, heart rate, etc. generated by analyzing each of the biological signals measured in S500 and both the electrocardiogram signal and pulse wave signal measured in S500 by a well-known method are used as the second biological information. Generate as

In S530, the difference between each of the second biological information generated in S520 and each of the first biological information stored in the storage device 16 is calculated as a biological information change amount.
In S540, information (an example of specific information of the present invention, hereinafter referred to as an activity burden) that associates the biological information change amount calculated in S530 with the activity content estimated in S420 is generated, and S550 is generated. Proceed to Specifically, the degree of activity burden in the present embodiment is obtained by associating the biological information change amount itself with the activity content when the biological information change amount is calculated in a one-to-one correspondence relationship. That is, for example, if the activity content is a meal and the biological information is a blood glucose level, the activity burden level is “change amount of blood glucose level: XX (here, XX is a numerical value of the change amount) activity content: meal” It will be something like this.

  In S550, the activity burden generated in S540 is notified in the own vehicle. That is, a command is output to the control unit 36 of the navigation device 30 so that the activity burden is displayed on the display unit 33 and output from the voice output unit 35.

  Subsequently, in S560, the biometric information change amount itself and the activity burden are set as transmission information, and the process proceeds to S570. In S570, the transmission information set in S560 is installed in the medical institution via the communication device 18. Transmit to the device group 60.

Thereafter, the biometric information generation process is terminated.
That is, in the biological information generation process of the present embodiment, a plurality of measurement timings based on the activity content estimated for each driver are set, and the biological information is generated according to the biological signals measured at those measurement timings. A biological information change amount is derived from the biological information. Then, an activity burden level in which the biological information change amount is associated with the activity content is generated, and the activity burden level and the biological information change amount are transmitted to the medical institution installation apparatus group 60 as transmission information.
[Effects of Second Embodiment]
As described above, according to the in-vehicle device 5 of the present embodiment, by transmitting the activity burden level to the medical institution installation device group 60, the medical institution installation device group 60 can collect the activity burden level. By reflecting the collected activity burden on the medical practice, it is possible to improve the accuracy of the medical practice (for example, medical examination).

For example, it is assumed that a meal at an eating and drinking facility is estimated as the activity content, and that the blood glucose level of the driver is derived as biometric information.
In such a case, the in-vehicle device 5 of the present embodiment acquires a blood glucose level before and after a meal, and transmits the change amount of the blood glucose level to the medical institution together with information indicating that the meal has been eaten. Therefore, the medical staff can recognize why the blood glucose level has changed and whether the amount of change is within an appropriate range.

By the way, according to the biometric information generation process of this embodiment, since the degree of activity burden is reported in the own vehicle, the amount of biometric information change can be recognized by the occupant, and the driver can be prevented from being excessively active. .
[Third embodiment]
Next, a third embodiment of the present invention will be described.

In the biological information management system of the present embodiment and the biological information management system 1 of the first embodiment, a part of the configuration of the in-vehicle device 5, a processing program stored in the ROM 11 of the control device 10, and the CPU 13 are executed. Only the processing is different. For this reason, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. The description will focus on processes different from those in the first embodiment.
<In-vehicle device configuration>
Here, FIG. 8 is a block diagram showing a schematic configuration of the biological information management system 1 and the medical institution installation device group 60 and the in-vehicle device 5 constituting the biological information management system 1 in the present embodiment.

  The in-vehicle device 5 includes a measuring device 20, a communication device 18, a storage device 16, a timing device (not shown), a data reading device 17, and a brake control device 19 that controls a brake mechanism mounted on the host vehicle. And a control device 10.

Among these, the brake control device 19 controls the brake mechanism in accordance with a command from the control device 10 so as to increase the braking force of the host vehicle.
The control device 10 is configured around a well-known microcomputer including at least a ROM 11, a RAM 12, a CPU 13, and a bus connecting them.

  The ROM 11 determines whether or not the driver has performed treatment based on the biological information generated according to the biological signal detected from the driver and the medical information, the driver's arousal state, and these determinations. A processing program for the CPU 13 to execute a vehicle control process for controlling the host vehicle so as to reduce the risk of traveling according to the result is stored.

Note that the ROM 11 is used to determine the initial value of the measurement timing for measuring a biological signal (in this embodiment, the interval is 30 seconds) and the driver's arousal state in vehicle control processing. Stores a drowsiness determination threshold defined in advance.
<Vehicle control processing>
Next, vehicle control processing executed by the CPU 13 will be described.

Here, FIG. 6 is a flowchart showing a processing procedure of the vehicle control processing.
This vehicle control process is started at specified intervals when the internal combustion engine of the host vehicle is started (in this embodiment, an ignition signal is input).

  When the vehicle control process is started, as shown in FIG. 6, first, in S610, it is determined whether or not medical information has been acquired, that is, when the vehicle control process is executed before the previous time. It is determined whether or not information has been acquired. If medical information has not been acquired as a result of the determination, the process advances to step S620.

In S620, the process waits until the medical information is acquired. When the medical information is acquired, the medical information is stored in the RAM 12 or the storage device 16, and the process proceeds to S630.
In S630, the current time is acquired from the timing device, and it is determined whether or not the acquired current time is the measurement timing stored in the ROM 11. If the result of determination is not the measurement timing, the measurement timing is reached. Until the measurement timing comes, the process proceeds to S640.

  In S640, all types of biological signals preset as measurement targets are measured, and the process proceeds to S650. Specifically, in the present embodiment, at least four of an electrocardiogram signal, a pulse wave signal, a skin temperature (ie, body temperature), and a facial image are measured as biological signals.

  In S650, it is determined whether or not all types of biological signals have been measured. If all types of biological signals have not been measured as a result of the determination, the process returns to S640 until all types of biological signals are measured. When the measurement of the biological signal is repeated and all the biological signals are measured, the process proceeds to S660. In the present embodiment, as a case where an electrocardiogram signal or a pulse wave signal is not measured, for example, a case where the driver releases one hand from the steering wheel S and operates the shift lever of the host vehicle may be considered.

  In S660, blood pressure and heart rate generated by analyzing each of the biological signals measured in S640 and both the electrocardiogram signal and pulse wave signal measured in S640 by a well-known method are generated as biological information. . In S670, the biometric information generated in S660 is stored in the storage device 16 in association with the biometric information generation time in S660, and the process proceeds to S680.

  In S680, the difference between each biometric information generated in the vehicle control process activated this time and the biometric information generated in the vehicle control process activated before the previous time and stored in the storage device 16, Calculated as the biological information change amount.

  Subsequently, in S690, among the setting threshold values included in the medical information, the setting threshold value for the treatment that may affect the driving of the host vehicle (hereinafter referred to as the treatment determination threshold value), and the biological information change calculated in S680 By comparing with the amount, it is determined whether or not the treatment content in the medical information has been executed. If it is determined that the treatment content in the medical information has been executed, the process proceeds to S700.

  For example, it is assumed that antipyretic medication is set as the treatment content, and the side effect information includes information indicating that there is a possibility that the arousal level may decrease (or the degree of reduction in the arousal level). And if the biometric information (namely, body temperature) produced | generated over the regulation frequency prescribed | regulated previously becomes smaller than a treatment determination threshold value, you may determine with the antipyretic agent having been taken. However, it is desirable to set the driver's body temperature to be achieved by taking the antipyretic as the treatment determination threshold.

  In S700, the sleepiness determination threshold is changed from the initial value so that it is estimated as a state in which the degree of wakefulness is reduced in the wakefulness determination described below. This is because, as a result of the determination in S690, the driver executes the treatment content included in the medical information (for example, taking a medicine that may decrease the arousal level), This is because there is a possibility that the arousal level may decrease, and it is required to drive the vehicle more safely than when driving without taking medicine.

  Subsequently, in S710, first vehicle control for outputting a command to the brake control device 19 is executed so as to reduce the speed of the host vehicle to a first specified speed (for example, 30 km / h) specified in advance. Proceed to With this first vehicle control, when the driver executes the treatment content (for example, taking a medicine that may reduce the arousal level), the vehicle speed is reduced to the first specified speed.

On the other hand, as a result of the determination in S690, if it is determined that the treatment content in the medical information has not been executed, the process proceeds to S720 without executing S700 and S710.
In S720, the facial image for a preset time that is past the current time is analyzed, and the driver's arousal level is calculated. Specifically, in the present embodiment, the degree of arousal is calculated to be higher as the opening degree of the upper eyelid and the lower eyelid is larger by a known image analysis method.

Subsequently, in S730, it is determined whether or not the arousal level calculated in S720 is equal to or less than the drowsiness determination threshold set at the time of proceeding to S730. If the driver feels sleepy, the process proceeds to S740. It should be noted that the sleepiness determination threshold used in S730 is determined by the awakening degree when the process proceeds to S730 via S700 (that is, when a treatment that may affect the driving of the host vehicle is performed). It has been changed so as to be estimated as a lowered state. Moreover, when it progresses to S730, without passing through S700 (namely, when the treatment which may affect the driving | operation of the own vehicle is not performed), it is an initial value.

  In S740, a command is output to the brake control device 19 so as to reduce the speed of the host vehicle to a second specified speed (for example, 10 km / h) preset as a speed lower than the first specified speed. Two vehicle control is executed. When the driver feels sleepy by this second vehicle control, the vehicle speed is reduced to the second specified speed.

Thereafter, the vehicle control process is terminated.
On the other hand, as a result of the determination in S730, if the arousal level is greater than the drowsiness determination threshold, it is determined that the driver does not feel drowsiness, and the vehicle control process is terminated without executing S720.

That is, in the vehicle control processing of the present embodiment, biometric information is generated according to a biosignal measured from the driver, and the medical information generated for each driver in the medical institution is generated based on the generated biometric information. It is determined whether or not the treatment content has been executed. If the result of the determination is that the treatment content has been executed, the brake mechanism is controlled so that the vehicle speed of the host vehicle decreases. Then, if the treatment content is being executed, the sleepiness determination threshold is changed so that the state of awakening is reduced in the state of awakening determination, and if the driver's awakening is lower than the changed sleepiness determination threshold Furthermore, the brake mechanism is controlled so that the vehicle speed of the host vehicle decreases.
[Effect of the third embodiment]
As described above, according to the in-vehicle device 5 of the present embodiment, the vehicle is controlled according to the driver's situation, such as whether or not the driver has executed the treatment content and the driver's arousal state. can do.

For example, it is assumed that the driver takes a medicine (hereinafter referred to as a major side effect medicine) that is likely to decrease the arousal level as a side effect immediately before or during driving of the vehicle.
In such a case, in the vehicle control process of the present embodiment, if it is determined that a major side-effect drug has been taken based on the biological information change amount, the vehicle is controlled so that the vehicle speed decreases. For this reason, according to the in-vehicle device 5 of the present embodiment, when the driver takes a major side-effect drug, the danger during traveling is greater than during normal driving (that is, when the drug is not taken). The vehicle can be controlled so as to decrease.

  Furthermore, in the vehicle control process of the present embodiment, when it is determined that a major side effect drug has been taken based on the biological information change amount, sleepiness determination is performed so that the state of wakefulness is determined to be determined by the state of wakefulness determination. Change the threshold. For this reason, according to the vehicle control processing of the present embodiment, when the driver takes a major side effect drug, the danger during traveling can be more reliably reduced.

Note that S620 in the vehicle control process of the present embodiment corresponds to the medical information acquisition unit of the present invention, and S630 to S740 correspond to the vehicle control unit. Further, S660 corresponds to the biological information generation means, S670 corresponds to the biological information accumulation control means, S680 corresponds to the change amount derivation means, S690 corresponds to the treatment execution determination means, and S730 corresponds to the situation estimation means. S700 corresponds to threshold setting means.
[Other Embodiments]
As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, In the range which does not deviate from the summary of this invention, it is possible to implement in various aspects.

  For example, in S140 in the biometric information generation process of the first embodiment, the measurement timing is set so that the measurement interval at a fixed time before and after the scheduled dose time (that is, the scheduled treatment time) is shorter than the specified interval. However, the setting of the measurement timing is not limited to this, and may be only a plurality of prescribed times defined in advance before the scheduled dosing time, or may be a point in time when a plurality of prescribed times have elapsed from the scheduled dosing time.

  Moreover, in S280 in the biometric information generation process of the first embodiment, the treatment guidance is immediately notified if the driver does not execute the treatment content, but the treatment guidance notification is repeated a prescribed number of times, You may make it perform when biometric information change amount is more than a setting threshold value.

  In this way, the possibility that the drivers feel annoyance can be reduced by making the biological information change amount equal to or greater than the set threshold value and notifying treatment guidance by mistake due to a measurement error or the like.

  Note that it is not necessary to execute all the steps executed in the biometric information generation process of the first embodiment. For example, S250 and S260 may be omitted, or S270 and S280 may be omitted. good. Further, S310 and S320 may be omitted.

  By the way, in S560 in the biometric information generation process of the second embodiment, the biometric information change amount itself and the activity burden are set as transmission information. However, the transmission information set in S560 is not limited to this. Instead, for example, the first biological information and the second biological information itself and the activity content may be used. That is, when the activity content is a meal and a blood glucose level is generated as biological information, the first biological information that is the blood glucose level before the meal, the second biological information that is the blood glucose level after the meal, and the activity content are Information indicating that it is a meal may be generated as transmission information.

  Moreover, in the biometric information generation process in the second embodiment, the biometric information generation amount and the activity content itself are generated as a degree of activity burden only by associating with a one-to-one correspondence relationship. The activity burden generated by the process is not limited to this, and is information newly generated in a manner that can identify that the biological information has changed by the amount of change in the biological information depending on the activity content. Also good. In this case, for example, if the activity content is a meal and the biological information is a blood sugar level, the activity burden level is information such as “the blood sugar level has increased XX due to the current meal”.

  In S540 in the biometric information generation process of the second embodiment, the activity burden level is generated by associating the biometric information change amount with the activity content. However, the activity load level generation method is not limited to this. Instead, information input via the operation switch unit 32 of the navigation device 30 may be added to the biological information change amount and the activity content. In other words, for example, when the activity content is a meal, the driver is made to input what kind of meal was eaten via the operation switch unit 32, and that the activity content is a meal and the content of the meal (for example, , Ingested energy amount) and the change amount of the blood glucose level as the biological information change amount may be generated as the activity burden.

  Furthermore, also in the biological information generation process of the second embodiment, as with the biological information generation process of the first embodiment, a warning given by a medical person to the driver based on transmission information from the in-vehicle device 5 Or advice (that is, advice information) may be acquired, and the acquired advice information may be reported in the vehicle.

  In the biological information generation process in the second embodiment, the current position of the host vehicle, the facility data existing at the current position, and the activity time are acquired from the navigation device 30 as the behavior information. It is not restricted to what is acquired from the navigation device 30.

For example, the behavior information may be acquired from a well-known information processing device or communication device that is provided separately from the in-vehicle device and is installed in a facility where the driver is planning an activity. In this case, the acquired behavior information is information indicating what kind of activity the driver was doing in the facility where the information processing device or the like was installed (for example, what kind of exercise is performed if it is an exercise facility) It is desirable that how much energy is consumed, what kind of meal is eaten and how much energy is consumed if it is a dining facility.

  Further, the driver's schedule may be acquired as behavior information from a well-known scheduling function provided in the navigation device 30 or a scheduler possessed by the driver. In such a case, the estimation accuracy of the activity content can be improved.

  Furthermore, the blood glucose level sensor 24 in the above embodiment is a well-known sensor that measures the blood glucose level by analyzing the reflection spectrum. However, the blood glucose level sensor 24 is not limited to this, for example, a driver. A well-known sensor may be provided that includes a needle-like intubation unit that collects blood from the blood vessel and an analysis unit that measures blood glucose level by analyzing blood collected by the intubation unit.

  In the vehicle control process of the third embodiment, the vehicle speed is reduced to the first specified vehicle speed at S710 and the vehicle speed is reduced to the second specified vehicle speed at S740. However, the present invention is not limited to this. For example, control may be performed so as to decrease the vehicle speed only when both S690 and S730 are affirmative.

  By the way, for example, when a driver receives an infusion at a medical institution, the driver can be said to be in poor physical condition as it needs to receive an infusion. In such a case, the driver is more likely to have a reduced judgment ability or the like necessary for driving the vehicle as compared to when the physical condition is normal (that is, good). It is required to drive the vehicle more safely.

  For this reason, in the vehicle control process of the third embodiment, when medical information is acquired, the diagnosis result of the medical information has a high possibility of affecting the driving of the host vehicle (that is, in a medical institution). Controls to immediately reduce the vehicle speed if there are any indications such as administration of infusions or medical examinations that have been performed at a medical institution if the physical condition is significantly worse than normal. You may do it.

  In S730 in the vehicle control process of the third embodiment, the awake state is determined as the driver state. However, the driver state determined in S730 is not limited to the awake state. It may be physical condition or attention.

  In the vehicle control process of the third embodiment, the speed of the vehicle is reduced as a control for reducing the danger during traveling of the host vehicle, but the risk for reducing the danger during traveling of the vehicle is reduced. Control is not limited to this. For example, when treatment is performed or when the arousal level is reduced, the inter-vehicle distance is increased compared to when treatment is not performed or when the arousal level is high. You may control. However, when performing vehicle control in this way, a well-known cruise control system is mounted on the host vehicle, and the control device 10 needs to output a command to the cruise control system so as to increase the inter-vehicle distance. .

  By the way, in the biological information generation process or the vehicle control process of the above embodiment (here, all of the first, second, and third), the biological signal is measured at the measurement timing, and the biological information is obtained from the measured biological signal. Although generated, the biological signal used to generate biological information is not limited to this. For example, a biological signal measured at a measurement timing is extracted from biological signals measured at regular intervals (for example, one minute interval) and stored in the storage device 16 or the like, and biological information is extracted from the extracted biological signals. May be generated, or biological information may be generated from an average of biological signals measured between measurement timings.

  Furthermore, the biological information generated by the above-described biological information generation processing and vehicle control processing was an electrocardiogram signal, a pulse wave signal, body temperature, heart rate, blood pressure, facial image, etc. Is not limited to this, for example, an index indicating vascular stiffness such as pulse wave propagation time derived by analyzing a pulse wave signal and an electrocardiogram signal, or an autonomic nerve indicating an active state of an autonomic nerve You may make it produce | generate an activity parameter | index, a driver | operator's sweat state, eye movement, respiration, etc. as biometric information.

  In the biometric information generation process or the vehicle control process in the above embodiment (here, all of the first, second, and third), a command is output to the navigation device 30 and the display unit 33 of the navigation device 30 Although various notifications were executed by controlling the voice output unit 35, the display device and the voice output device for performing the notification are not limited to those constituting the navigation device 30 and are provided exclusively for the in-vehicle device 5. May be.
