Description

The present invention relates to a safe driving support system that provides support during vehicle driving in consideration of the driver's health condition. One embodiment of the present invention relates, in particular, to a safe driving support system that supports driving a vehicle by a patient with hypoglycemia.

In recent years, in collaboration with the government and automobile manufacturers, vehicles equipped with automatic braking and acceleration suppression devices when the pedal is pressed incorrectly (safe driving support vehicles) are becoming widespread. The safe driving support vehicle was developed as a countermeasure against an increase in the number of fatal accidents caused by elderly drivers aged 75 and over, and is provided with a function for dealing with erroneous operation by the driver. In addition, various attempts have been made to automatically drive automobiles, but they have not yet been put into practical use.

On the other hand, in addition to fatal accidents caused by elderly drivers, fatal accidents caused by impaired driver's consciousness have become a social problem in recent years. Under these circumstances, Article 3 (Vehicular homicide) of the Act on Punishment for Acts of Injuring People by Driving a Car, which came into effect on November 27, 2013, states that the car Driving a car in a state where there is a risk that normal driving may be hindered while driving due to the influence of a disease specified by a government ordinance as a disease that may interfere with driving, and therefore normal driving due to the influence of the disease It is stipulated that a person who falls into a difficult state and injures a person shall be punished by imprisonment with work for not more than 12 years, and a person who has killed a person shall be punished by imprisonment with work for not more than 15 years (so-called sick driving fatal injury). ing.

In addition, as a illness that may interfere with the driving of a car, Article 3 of the Ordinance for Enforcement of the Act on Punishment for Acts of Injuring People by Driving a Car, which was enforced on May 20, 2014, states that a car is used. Symptoms that may result in a lack of cognitive, predictive, judgmental, or operational abilities necessary for safe driving. Syncope, impaired consciousness, or epilepsy that results in impaired motor movements. (Excluding those in which the attack recurs only during sleep.), Recurrent syncope (a disease that causes transient disturbance of consciousness due to ischemia of the entire brain and in which the attack may recur. ), Hypoglycemia with symptoms that may result in lack of cognitive, predictive, judgmental or operational abilities necessary for safe driving of the car, cognitive, predictive, necessary for safe driving of the car, Syncope (including syncope and depression), which presents with symptoms that may result in inability to perform either judgment or manipulation, and sleep disorders, which present with symptoms of severe drowsiness, are specified.

Here, hypoglycemia is a disease characterized in that the blood glucose level is low and sympathetic nerve symptoms and central nervous system symptoms are present. Sympathetic symptoms are symptoms such as sweating, palpitation, and hand tremor. Central nervous system symptoms include dizziness, drowsiness, weakness, poor concentration, convulsions, and coma, which can cause permanent brain damage if the response is delayed. Since the blood glucose threshold at which sympathetic nerve symptoms appear is higher than the blood pressure threshold of central nervous system symptoms, generally, the sympathetic nerve symptoms are noticed before the onset of central nervous system symptoms. However, elderly people, patients with autonomic neuropathy, repeated hypoglycemia, and infants may suddenly develop fainting or coma without sympathetic symptoms, which is called unaware hypoglycemia. In the case of unaware hypoglycemia, it is often difficult to control blood glucose, and if the blood glucose cannot be controlled artificially, a driver's license may not be granted or may be suspended. On the other hand, even in patients with hypoglycemia, it is often possible to suppress the onset by ingesting sugar and taking appropriate drugs. Therefore, a non-conscious hypoglycemic patient or a hypoglycemic patient who can artificially adjust the blood glucose level can obtain or renew a driver's license for a car.

Hypoglycemia is particularly frequent in diabetic patients who are using insulin, sulfonylurea drugs, fast-acting insulin secretagogues, etc., and the number of diabetic patients is increasing year by year. Currently, it is estimated that there are 10 million diabetics in Japan as a whole. In addition, it is known that hypoglycemia occurs even with some antiarrhythmic agents and quinolone-based antibacterial agents, even if they are not antidiabetic agents. Since automobiles are one of the main means of transportation, banning the driving of hypoglycemic patients whose onset is sufficiently suppressed is a major obstacle for hypoglycemic patients to lead an independent life. Can be. Therefore, it is desired to develop a safe driving support system capable of responding to the sudden onset of hypoglycemia during driving.

As a vehicle control system that controls a vehicle in consideration of the driver's health condition, for example, Patent Document 1 includes a wearable terminal that is attached to the driver's body to acquire the driver's biological information, and a communication unit. However, in a vehicle control system including an in-vehicle device mounted on a vehicle to control the vehicle, the in-vehicle device is a permissible information storage unit that stores permissible information for determining whether or not biometric information is normal. , Using the biometric information receiving unit that acquires biometric information from the wearable terminal and the permissible information stored in the permissible information storage unit, it is determined whether or not the biometric information received by the biometric information receiving unit is within the permissible range. It is described that the reference determination unit is provided and a vehicle control unit that decelerates and stops the running vehicle in response to the determination that the biometric information is out of the permissible range by the reference determination unit. ..

Further, Patent Document 1 describes that when it is determined that the biological information is out of the permissible range, warning information is transmitted to a vehicle located in the vicinity that the driver cannot drive. Has been done. Further, in Patent Document 1, the traveling position of the vehicle is specified from the car navigation system mounted on the vehicle, and it is determined whether or not the vehicle can be slowed down and stopped according to the specified traveling position of the vehicle. It is also described that the vehicle is stopped.

In one embodiment, the sensor 13 (first sensor) is a device that acquires biometric information from the driver 1 and includes, for example, at least one of a pulse rate monitor, a thermometer, and a sweat meter. Here, the pulse rate measured by the pulse rate monitor is treated as substantially synonymous with the heart rate, and the body temperature measured by the thermometer is treated as substantially synonymous with the skin temperature. In the present embodiment, the sensor 13 has an integrated configuration included in the wearable terminal 10, but the sensor 13 may have a configuration separate from the wearable terminal 10. For example, when detecting cold sweat, which is local sweating, the sweat meter may be integrated with the handle 40 to detect the amount of sweating on the palm. It is more preferable to select the sensor 13 having a large difference between the biological information of the driver 1 in the normal state and the permissible information of the driver 1 described later.

Here, the glucose concentration in the interstitial fluid measured by the interstitial fluid glucose concentration measuring unit 41 is treated as having substantially the same meaning as the blood glucose level. If the blood glucose level is detected as a predetermined number, less than 70 mg / dL in the present specification, the risk of subsequent central nervous system symptoms increases. Therefore, it may be acceptable information that the blood glucose level is 70 mg / dL or more. If the blood glucose level is detected to be less than 50 mg / dL, it indicates that hypoglycemia has already occurred, and the risk of becoming unconscious even in the absence of sympathetic nerve symptoms is very high. Therefore, the permissible information may be that the blood glucose level is 50 mg / dL or more. The blood sugar levels at which hypoglycemia may occur vary from patient to patient. Therefore, in one embodiment, permissible information based on the fluctuation of the blood glucose level, that is, the rate of decrease in the blood glucose level may be used. A sharp drop in blood sugar increases the risk of hypoglycemia, even at high absolute values. A plurality of allowable information based on the blood glucose level may be used. By having a plurality of stages of blood glucose levels as permissible information, the accuracy of detecting the hypoglycemic symptom of the driver 1 is improved.

It may be performed via a communication means conforming to the wireless communication standard provided in 16.

The wearable terminal 10 may have an authentication code such as a bar code on the surface of the wearable terminal 10 instead of the authentication information storage unit and the permissible information storage unit. When the safe driving support in-vehicle device 30 is equipped with a camera capable of reading the authentication code (for example, an image sensor such as a CCD or CMOS), the authentication code is imaged by the camera and the authentication captured by the safe driving support in-vehicle device 30. The code may be recognized and the permissible information of the driver 1 corresponding to the authentication code may be received from the server 101. The authentication code may be a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

It also has communication means conforming to wireless communication standards such as Wi-Fi and Bluetooth, but is not limited to these. A physical address (MAC address) is assigned to the communication unit 26, and the dedicated transmitter / receiver 20 can be specified from the physical address. Therefore, in the above-described embodiment, the driver 1 is specified based on the physical address assigned to the communication unit 16 of the wearable terminal 10, but based on the physical address assigned to the dedicated transmitter / receiver 20. The driver 1 may be specified.

In one embodiment, the dedicated transmitter / receiver 20 may be connected to a plurality of wearable terminals 10. That is, a plurality of wearable terminals 10 may be connected to the safe driving support in-vehicle device 30 or the server 101 via one dedicated transmitter / receiver 20.

The power source 53 is, for example, a battery mounted on the vehicle 50. Further, in one embodiment, the safe driving support vehicle-mounted device 30 connects the communication unit 34 to the interstitial fluid glucose concentration measuring unit 41 and the other sensors 43. Further, in one embodiment, the safe driving support vehicle-mounted device 30 is connected to the position information receiving unit 55. Further, in one embodiment, it is preferable that the safe driving support vehicle-mounted device 30 is connected to the vehicle control unit 51 via the unified standard conversion unit 52.

In one embodiment, the control unit 31 is a device that controls the safe driving support vehicle-mounted device 30, for example, a central processing unit (CPU). Further, the control unit 31 includes a program for controlling the safe driving support vehicle-mounted device 30. The program for controlling the safe driving support vehicle-mounted device 30 is stored in the storage unit 32 and executed by the control unit 31. Further, in one embodiment, the control unit 31 may include an operating system (OS) that controls the safe driving support vehicle-mounted device 30, and an application program or module that functions in the safe driving support system 100.

In one embodiment, the control unit 31 includes an authentication unit 31a and a reference determination unit 31b. The authentication unit 31a is an application program or module for authenticating the driver 1. The authentication unit 31a can identify the driver 1 based on the physical address assigned to the communication unit 16 of the wearable terminal 10 or the physical address assigned to the communication unit 26 of the dedicated transmitter / receiver 20. Further, when the authentication information of the driver 1 includes a code or the like indicating that the driver 1 is permitted to drive the vehicle, the authentication unit 31a causes the vehicle control unit 51 to send the driver. The driving of the vehicle 50 by 1 may be permitted. If the driver 1's authentication information does not include a code or the like indicating that the driver 1 is permitted to drive the vehicle, the driver 1 operates to start the engine of the vehicle 50. Alternatively, the engine starting operation may be interrupted via the vehicle control unit 51. Further, the authentication unit 31a includes information that can identify the driver 1, for example, the weight of the driver 1, fingerprint information, and face information in the authentication information of the driver 1, and the authentication unit 31a uses a sensor 43 that can identify these. When provided, the driver 1 can be authenticated based on these authentication information.

In one embodiment, the reference determination unit 31b is measured from the permissible information of the driver 1 stored in the server 101 or the wearable terminal 10 and at least from the sensor 13 of the wearable terminal 10 and the glucose concentration measuring unit 41 in the interstitial fluid. It is an application program or module for controlling the operating state of the vehicle 50 by comparing it with biometric information. As described above, the permissible information of the driver 1 is set by the medical staff and stored in the server 101 or the wearable terminal 10. In one embodiment, the safe driving support vehicle-mounted device 30 may receive the permissible information of the driver 1 from the server 101 or the wearable terminal 10 via the communication unit 34 and store it in the permissible information storage unit 32a. By storing the permissible information of the driver 1 in the permissible information storage unit 32a, the safe driving support in-vehicle device 30 can be used by the driver from the permissible information storage unit 32a while the driver 1 is driving the vehicle 50. The permissible information of 1 can be read and compared with the measured biometric information.

In one embodiment, when the driver 1 is a hypoglycemic patient, the reference determination unit 31b determines, for example, at least one of the absence of an increase in heart rate, skin temperature change, or sweating, and the blood glucose level. The reference tolerance information can be used to compare with the measured biometric information. For example, if at least one of a predetermined number or more of heart rate, a predetermined number of skin temperature changes or more, an increase of sweating amount of a predetermined number or more, or a blood glucose level of less than 70 mg / dL is detected, then central nervous system symptoms occur. Increased risk of occurrence. Therefore, as the permissible information stored in the permissible information storage unit 32a, the heart rate is less than a predetermined number, the skin temperature change is less than a predetermined number, the increase in sweating amount is less than a predetermined number, or the blood glucose level is 70 mg / dL or more. When the information is stored, the reference determination unit 31b determines that the heart rate of the driver 1 measured by the sensor 13 is less than a predetermined number, the skin temperature change is less than a predetermined number, the increase in sweating amount is less than a predetermined number, or blood glucose. If the value is 70 mg / dL or more, no special signal is transmitted to the vehicle control unit 51, or a signal permitting driving is transmitted. On the other hand, at least one of the heart rate of the driver 1 measured by the sensor 13 is a predetermined number or more, the skin temperature change is a predetermined number or more, the increase in sweating amount is a predetermined number or more, or the blood glucose level is less than 70 mg / dL is detected. If so, as will be described later, the reference determination unit 31b transmits a signal to the output unit 33 to display and output a voice to call attention to sugar supplementation. Further, the heart rate of the driver 1 measured by the sensor 13 is at least one of a predetermined number or more, the skin temperature change is a predetermined number or more, the increase in sweating amount is a predetermined number or more, and the blood glucose level is less than 70 mg / dL. When it is detected, the reference determination unit 31b transmits a signal for causing the output unit 33 to display and output a voice to call attention to the stop, as will be described later.

Further, for example, when a blood glucose level of less than 50 mg / dL is detected, it indicates that hypoglycemia has already occurred, and there is a very high risk of becoming unconscious even without sympathetic nerve symptoms. Therefore, when the permissible information stored in the permissible information storage unit 32a stores that the blood glucose level is 50 mg / dL or more, the reference determination unit 31b measures the glucose concentration in the interstitial fluid concentration unit 41. When the blood glucose level of the driver 1 is 50 mg / dL or more, no special signal is transmitted to the vehicle control unit 51, or a signal permitting driving is transmitted.
