Description

The present invention relates to a safe driving support system that provides support when driving a vehicle in consideration of the health condition of the driver. One embodiment of the present invention particularly relates to a safe driving support system that supports driving of a car by a patient with heart disease.

In recent years, vehicles (safe driving support vehicles) equipped with an automatic brake, an acceleration suppression device when a pedal is mistakenly pressed, and the like are becoming widespread in cooperation with the government and automobile manufacturers. The safe driving support vehicle was developed as a countermeasure against an increase in the number of fatal accidents caused by an elderly driver over 75 years old, and is provided with a function corresponding to an erroneous operation by the driver. Various attempts have been made to automatically drive automobiles, but they have not been put into practical use.

On the other hand, in addition to fatal accidents caused by elderly drivers, in recent years, fatal accidents caused by drivers' consciousness disturbances and the like have become social problems. Under such circumstances, Article 2 of the Act on Punishment for Acts of Injury to People by Driving a Car that came into effect on November 27, 2013 (Dangerous Driving Lethal and Injury) Driving a car in a state where normal driving may be hindered during the driving due to the influence of a disease specified by a Cabinet Order as a disease that may impede driving, so normal driving due to the influence of the disease It is stipulated that those who fall into a difficult state and are killed or injured shall be punished by imprisonment for 12 years or less, and those who killed a person shall be punished by imprisonment for 15 years or less (so-called sick driving lethal injury) ing.

In addition, Article 3 of the Ordinance for Enforcement of the Act on Punishment of Acts that Causes Death or Injury by Driving a Car that came into force on May 20, 2014 as a disease that may interfere with driving a car Epilepsy that may lead to recurrence of schizophrenia, consciousness disorder, or movement disorder that presents with symptoms that may result in lack of the ability to recognize, predict, judge, or operate necessary for safe driving (Excluding those in which the seizure recurs only during sleep), recurrent syncope (a disease that causes temporary consciousness disturbance due to ischemia of the entire brain, and the seizure may recur. ), Hypoglycemia with symptoms that may lead to lack of ability to recognize, predict, judge or operate necessary for safe driving, recognition, prediction necessary for safe driving, Cross or (including mania and depression.) Or so depressive exhibits symptoms that could be the lack of ability of the operation, and sleep disorders with symptoms of severe sleepiness are defined.

Arrhythmia is a disease that causes recurrent syncope. Arrhythmia is a condition that indicates abnormal cardiac rhythm and is characterized by extrasystole, tachycardia, and bradycardia. In addition, patients who have been implanted with an implantable cardioverter defibrillator (ICD) or biventricular pacing function (CRT-D) are prohibited from driving in principle. It is necessary to submit to the prefectural public safety committee a medical certificate written by a doctor who has taken the ICD training sponsored by the Japan Heart Rhythm ECG Society or the Japan Heart Failure Society in order to maintain a driving permit and a car driving license. .

However, patients with arrhythmias and implantable cardioverter defibrillators (ICDs) and patients with biventricular pacing implantable cardioverter defibrillators (CRT-D) are often treated appropriately It is possible to suppress extrasystoles, tachycardia, and bradycardia by proper administration and surgical treatment. In addition, it is estimated that there are more than 1.7 million patients with heart disease throughout Japan, and automobiles are one of the major means of transportation, so that extrasystoles, tachycardia and bradycardia were sufficiently suppressed. Prohibiting patients from driving a car can be a major obstacle to living independently for patients with heart disease. Therefore, it is desired to develop a safe driving support system that can cope with sudden extrasystoles, tachycardia, and bradycardia during driving.

As a vehicle control system that controls a vehicle in consideration of a driver's health condition, for example, Patent Document 1 includes a wearable terminal that is attached to a driver's body and acquires a driver's biological information, and a communication unit. And an on-vehicle device that is mounted on the vehicle and controls the vehicle, and the on-vehicle device includes an allowance information storage unit that stores allowance information for determining whether or not the biological information is normal. The biometric information receiving unit that acquires the biometric information from the wearable terminal and the permissible information stored in the permissible information storage unit are used to determine whether the biometric information received by the biometric information receiving unit is within an allowable range. And a vehicle control unit that decelerates and stops the traveling vehicle in response to the biometric information being determined to be out of the allowable range by the reference determining unit. .

Patent Document 1 describes that, when it is determined that the biological information is out of the allowable range, the alert information is transmitted to a vehicle located in the vicinity that the driver cannot drive. Has been. Further, Patent Document 1 specifies a travel position of a vehicle from a car navigation system mounted on the vehicle, and determines whether it is possible to slow down and stop the vehicle based on the identified travel position of the vehicle. It also describes stopping the vehicle.

Hereinafter, a safe driving support system according to the present invention will be described with reference to the drawings. The safe driving support system according to the present invention is not construed as being limited to the description of the embodiment described below. Note that in the drawings referred to in this embodiment, the same portions or portions having similar functions are denoted by the same reference numerals, and repetitive description thereof is omitted.

FIG. 1 is a schematic diagram showing a safe driving support system 100 according to an embodiment of the present invention. The safe driving support system 100 includes, for example, a wearable terminal 10 and a safe driving support in-vehicle device 30. FIG. 2 is a schematic diagram showing a safe driving support system 100a according to an embodiment of the present invention. The safe driving support system 100a is a safe driving support system that is an extension of the safe driving support system 100. For example, the vehicle 50, the server 101, the medical institution 110, the administrative institution 130, and the private company 140 that include the safe driving support system 100 are included. Although configured, the present invention is not limited to this. The server 101 is, for example, a server that can be connected to the safe driving support system 100 via wireless communication, and is connected to the medical institution 110, the administrative institution 130, and / or the private company 140 via wired communication or wireless communication. That is, the server 101 is a server that functions as a hub for connecting the safe driving support system 100 and the medical institution 110, the administrative institution 130, and / or the private company 140 in the safe driving support system 100a. The hardware of the server 101 is not particularly limited, and includes a known server and various electronic devices included in the known server.

In one embodiment, the server 101 may store the information of the driver 1 and the terminal identification information of the wearable terminal 10 in association with each other. The information of the driver 1 is the name, address, medical history, etc. of the driver 1 and may be any information that identifies the driver 1. Moreover, it is preferable that the information of the driver 1 includes, for example, a code indicating that the driver 1 is permitted to drive the vehicle. Moreover, the information which designates the sensor for monitoring the driver | operator 1 by the disease etc. of the driver | operator 1 may be included. In one embodiment, server 101 may store permissible information on driver 1. The permission information of the driver 1 is a standard based on biological information for allowing the driver 1 to drive the vehicle. Since the permissible information is also a criterion for restricting driving by the driver 1, depending on a disease or the like that the driver 1 has, the type of biological information and an appropriate criterion for each type of biological information are set by the medical staff. In one embodiment, when the driver 1 is a patient with heart disease, for example, tolerance information based on a heart rate and an electrocardiogram waveform can be used. For example, it is preferable that the authentication information of the driver 1 includes, for example, a code indicating that the driver 1 is permitted to drive the vehicle. Moreover, the information which designates the sensor for monitoring the driver | operator 1 by the disease etc. of the driver | operator 1 may be included. The permission information of the driver 1 is a standard based on biological information for allowing the driver 1 to drive the vehicle. Since the permissible information is also a criterion for restricting driving by the driver 1, depending on a disease or the like that the driver 1 has, the type of biological information and an appropriate criterion for each type of biological information are set by the medical staff. In one embodiment, when the driver 1 is a patient exhibiting arrhythmia, for example, tolerance information based on a heart rate and an electrocardiogram waveform can be used.

When the tolerance information based on the heart rate and the electrocardiogram waveform is used, it may be necessary to distinguish between an arrhythmia patient and a structural and functional change of the heart when sports are continued, so-called sports heart. Since the sports heart is not necessarily a morbid state, the patient's tolerance information indicating arrhythmia is appropriately set for each driver 1 by diagnosis by a medical worker considering individual differences. For example, when the heart rate is 50 times / minute or more, the possibility of bradyarrhythmia increases, and the possibility of falling into a lethal situation such as cardiac arrest increases. For example, when the heart rate is 120 times / minute or more, the possibility of tachyarrhythmia increases. Since the heart rate indicating arrhythmia varies among patients, it is appropriately set for each driver 1 by diagnosis by a health care professional. In one example, the heart rate is faster than 50 times / minute and 120 times / minute. It is good also considering that it is less than tolerance information (1st range). Further, in one example, the heart rate at which the possibility of bradyarrhythmia becomes higher is 40 times or less, and the heart rate at which the possibility of tachyarrhythmia becomes higher is 200 times / minute or more as a dangerous value (second Range). Furthermore, if the ECG waveform acquired by the electrocardiograph is classified as ventricular tachycardia or ventricular fibrillation, the risk of cardiac arrest is very high, so the ECG waveform acquired by the electrocardiograph is The permissible information may not be classified as a beat or ventricular fibrillation.

In one embodiment, the storage area for storing the information of the driver 1 of the server 101 and the storage area for storing the permission information of the driver 1 are stored in an area that can be accessed only by an expert such as a medical worker. It is preferable. The medical worker terminal 111 can rewrite the driver 1 information and the permissible information by connecting to the server 101. Therefore, in this embodiment, only the person who can operate the terminal 111 for medical workers, ie, experts, such as a medical worker, can rewrite the information of driver | operator 1, and permissible information.
