Japanese Patent Publication No. 2006-57822

  By the way, accidents that occur when the driver is an elderly person have been a problem. Such accidents are often caused by elderly drivers becoming victims, but there are many cases where elderly drivers become perpetrators, especially when elderly drivers become perpetrators. The family of older drivers will continue to have strong anxiety because the remaining family is likely to be burdened with a large burden.

  On the other hand, there is an idea that the elderly should just return the driver's license, but considering the environment where the elderly live and the relationship with the family, it is not necessary to drive to all the elderly Cannot be discussed together. For example, there are cases where an elderly couple living in the countryside alone or an elderly person who has his own work such as farming cannot live without a car.

  However, it cannot be denied that an elderly driver is more likely to cause an accident than a normal driver. For example, four major characteristics of an error that an elderly driver is liable to make are as follows. (2) Decreased concentration, (3) Deprived of other attention, (4) Difficult to see, etc. Accidents-Its Transition and Features-", Italda Information, [online], General Incorporated Traffic Accident Analysis Center, June 2007, No.68, p.2-12, [Search January 24, 2017] Internet <URL: See http://www.itarda.or.jp/itardainfomation/info68.pdf>).

  As described above, although the accident of the elderly driver is a conventional problem, a solution for this problem has hardly been considered. In particular, deterring older drivers from becoming victims may be sufficient to prevent accidents involving the entire driver, including ordinary drivers, but older drivers become victims of the accident. No specific measures have been considered.

  Therefore, an object of the present invention is to suppress the occurrence of danger caused by, for example, an elderly driver driving a vehicle, to reduce the possibility that the elderly driver becomes a perpetrator or victim of an accident, and The purpose is to provide equipment that allows the driver to drive with peace of mind.

  The object of the invention of the present application is not limited to this, and there is an intention to acquire the right by a divisional application, amendment, etc. for a configuration aiming to obtain an effect obtained from the configuration portion disclosed in the present specification and drawings. . For example, in this specification, a problem in which a place described as “can be” is read as “to be a problem” is disclosed in this specification, and a configuration for solving this problem is also divided and amended. Willing to acquire rights by The present applicant intends to make a part of the configuration described in the present specification as the scope of claims in the amendment or divisional application.

  (1) For example, a device that can be attached to a vehicle driven by an elderly driver, acquires vehicle information related to the vehicle driven by the elderly driver, and the elderly driver uses the vehicle information to acquire the vehicle. It may be characterized by determining whether or not the situation can be a perpetrator of an accident by driving, and causing the notification means to notify a warning based on the determination.

  In this way, in a situation where an elderly driver who drives a vehicle can be a perpetrator, a warning is notified to the elderly driver, thereby reducing the possibility that the elderly driver becomes a perpetrator. The driver's family can feel safer and have older drivers drive. In addition, driving a car can be a reason for going out, and it may be possible to prevent elderly drivers from being withdrawn from the house, leading to improved health.

  The device that can be attached to the vehicle may be used by being attached to a vehicle such as an automobile. For example, the device may include an attachment portion, and the attachment portion may be attached to an automobile dashboard or an upper windshield. Good.

  “Aged driver” means, for example, an elderly person who is not old enough to enter the facility, and is able to go to the toilet alone and eat rice at home before he / she needs care. Consider an elderly person. In addition, for example, it may be an elderly person who lives with his son in his 40s or 50s and works in the field during the daytime.

  For example, such an elderly person can drive a light truck and go to the field, but when he goes out, he accompanies his son and his wife so that only the area around his house is a single range of action by the vehicle. It is assumed that he is an old driver, does not pass a bus in the countryside, and lives in places where he needs a car to move within his own range of action, so he must be an elderly driver. Or, elderly people who do not live with their families and are indispensable for their daily lives will have to be elderly drivers because cars are indispensable for visiting hospitals and buying daily necessities.

  “Vehicle information about the vehicle” may be, for example, information acquired by the vehicle itself or information acquired by the device attached to the vehicle. For example, it is good also as information acquired with the sensor etc. which are equipped with the vehicle itself, and is good also as information acquired with the sensor etc. which are equipped with this machine.

  For example, external image information viewed from the inside of the vehicle or image information inside the vehicle, detection information detected by a detection device provided in the vehicle or a device attached to the vehicle, GPS information acquired by GPS, and the like may be used. . The image information may be acquired from a photographing device such as a camera, for example. The detection device may be a sensor such as a speed sensor or an acceleration sensor, for example.

  “Determining whether or not an elderly driver can become a perpetrator of an accident by driving the vehicle from the vehicle information” is determined, for example, by matching the acquired vehicle information with predetermined condition information Good. For example, the predetermined condition information may be incorporated into a program for operating the device according to the present invention or stored in a storage unit provided in the device. For example, the predetermined condition information is considered to be acquired by a vehicle in a past case that has become the perpetrator of an accident, and may be vehicle information. For example, an accident may be recorded by a vehicle simulator, and predetermined condition information may be determined based on the recorded vehicle information. Then, by comparing the condition information with the vehicle information, it is preferable to determine whether or not the elderly driver can become a perpetrator of the accident by driving the vehicle.

  In addition, “determining whether or not an elderly driver can become a perpetrator of an accident by driving a vehicle from vehicle information” means that, for example, the control means of the device according to the present invention is incorporated in the program. The predetermined condition information stored in the storage means or the acquired vehicle information may be compared with the acquired vehicle information to determine whether or not the vehicle information matches the condition information.

  In addition, “the situation where an elderly driver can become a perpetrator of an accident by driving a vehicle” may be determined by determining whether the single condition information such as image information, GPS information, or speed information is matched with predetermined condition information. Further, it is better to determine whether or not the plurality of pieces of information match the predetermined condition information. By determining conformity with a plurality of pieces of information, it is possible to qualify the “situation where an elderly driver can be a perpetrator of an accident” more appropriately than when determining conformity with a single piece of information. The predetermined condition information may be a plurality of condition information such as image information, GPS information, and speed information.

  When determining conformity between a plurality of pieces of information and predetermined condition information, for example, as in the configuration of (8) described later, the determination is made based on whether or not the traffic signal information and the speed information conform to the predetermined condition information. Good. In this case, the “predetermined condition” information may be, for example, information indicating that the traffic signal information is in a yellow signal or a red signal and the speed information is equal to or higher than a certain speed. In addition, (9) “flicker” described later may be determined based on whether or not a plurality of pieces of information such as acceleration information, speed information, GPS information, and image information conform to predetermined condition information.

  For example, a part of the “predetermined condition” information stored in the storage means may be a condition fixed as an initial setting, but the other part is as an individual setting in (2) described later. It can be set individually. Of the predetermined conditions, those for which conditions can be easily set may be set individually.

  “Notifying the warning based on the determination” may be processed, for example, so as to notify the warning when it is determined that a situation where an elderly driver can be a perpetrator of an accident meets a predetermined condition. Therefore, it is determined whether or not the situation of the vehicle is in conformity with a predetermined condition. If it is determined that the vehicle is in conformity, processing is performed so that a warning is issued. It is good to process.

  However, on the other hand, even if it is determined that the condition is such that an elderly driver can be a perpetrator of an accident, it may be processed so that a warning is not notified when other conditions are considered. In driving a vehicle, the situation in which the vehicle is placed may meet a plurality of conditions at the same time. In some cases, it may be possible to drive safely without warning.

  In addition, for example, when it is determined that a plurality of conditions are met, a warning may be notified. For example, based on the fact that the vehicle has moved to the left or right above a predetermined value at a predetermined speed or higher, an elderly driver It may be determined that the situation can be a perpetrator of an accident, and a warning is notified.

  For example, even if it is determined that the condition is met, if it is determined that the condition is not met, the warning may not be notified. For example, as described later in (11), on the condition that an oncoming vehicle does not come even if it is determined that an elderly driver can be a perpetrator of an accident because the vehicle has moved to the right beyond a predetermined value. It is good to process so as not to notify the warning.

  “Notifying a warning” may be, for example, a weaker warning than that of a general driver, may be a warning that gives attention, or may give advice, and may not be a strong beep. Since an older driver becomes shorter as he gets older, he should give a warning that will not surprise or frustrate. For example, the warning notification function may be switched between a warning for a general driver and a warning for an elderly driver weaker than a warning for a general driver.

  For example, the device according to the present invention may have the above-described control as a control mode for an elderly driver, and may have a control mode for a general driver other than the elderly driver, and more preferably both modes can be switched.

  In the mode for a general driver, for example, a device that can be attached to a vehicle driven by a general driver other than an elderly driver, obtains vehicle information about the vehicle driven by the general driver, and acquires the vehicle information from the vehicle information. It is preferable to determine whether or not the general driver can be a victim of an accident by driving the vehicle, and to notify the notification means of a warning based on the determination. For example, the warning function may be switched between a warning for a general driver and a warning for an elderly driver as described above, but a mode for a general driver and a mode for an elderly driver. It is more preferable that the mode is switched according to the mode switching.

  (2) For example, the elderly driver's family has a function of setting the situation where the elderly driver can become a perpetrator of an accident by driving the vehicle.

  In this way, the family of each elderly driver can individually make settings that are considered optimal for the elderly driver, and if the settings are appropriate, the situation is considered optimal for the elderly driver. Since warnings are reported, the anxious driver's anxiety is reduced and the family is more at ease compared to the case where the elderly driver can be the perpetrator of the accident. You can drive.

  The “function for setting the situation by the family of the elderly driver” may be, for example, a function for the family to set a part of a predetermined condition that is determined to be compatible with the acquired information. For example, a condition relating to “position information” in (3) described later may be set, or a condition relating to “signal information” and a condition relating to “speed information” in (8) may be set. For example, the set condition may be stored as setting data in the storage unit of the device.

  For example, the condition related to “position information” in (3) may be set as a condition that the vehicle reaches a specific position or a specific range. For example, the condition related to “signal information” in (8) It may be set as a condition that the color of the lamp is recognized as a predetermined color, and the condition relating to “speed information” may be set as a condition that the speed of the vehicle exceeds a certain threshold.

  For example, the device may include a display device, and the “function to be set” may be, for example, a function in which an item to be set is displayed on the display device and set by appropriately selecting the item. For example, a plurality of items including items for setting the situation related to climate information such as (12) are displayed on the display device. When (12) is selected, items such as temperature, weather, and humidity are displayed. When the temperature is selected, it is preferable to display such that the temperature at which the warning is notified is selected in increments of 1 degree. The selection may be performed by a setting unit such as an input button or a touch panel provided on the display device. Alternatively, the “function to be set” may be set by the external setting device in (5).

  Also, for example, items such as place, time, event, etc. that can be considered as “a situation where an elderly driver can become a perpetrator of an accident by driving a vehicle” and options for each item are prepared in advance. The family of the elderly should choose the option. Moreover, such a setting is good to repeat repeatedly many times in consideration of the state and driving | running condition of an elderly driver which change every day.

  For example, the “function set by the family of the elderly driver” may have a configuration that is more difficult for the elderly driver to set than the family of the elderly driver, and more desirably, the family of the elderly driver. It is recommended that only be set. For example, a function for inputting information for identifying the family of an elderly driver may be provided.

  Furthermore, this device may have a function that only the family can set, for example, a situation in which an elderly driver can become a perpetrator of an accident by driving a vehicle. It is good to have. For example, this device should have a function that requires a password, and a password is required before setting, and only a family member who knows the password can have a function that can be set by entering the password. It would be nice if no elderly driver has a function that cannot be set.

  (3) For example, when the elderly driver's family is able to become a perpetrator of an accident by driving the vehicle, the elderly driver's family is related to the position information where a risk peculiar to the elderly driver is predicted. It may have a function to set.

  In this way, since the warning is comprehensively notified at the position where the elderly driver is likely to be the perpetrator, the family can drive the elderly driver with more peace of mind. In addition, since the driving range of an elderly driver is limited, the position where danger is predicted is limited. Therefore, the family can set a unique position according to each elderly driver.

  The “danger unique to the elderly driver” is, for example, a danger common to ordinary elderly drivers, and may be a risk that focuses on the driving habits and driving habits of ordinary elderly drivers. For example, it may be a risk arising from a driving habit of a general elderly driver who repeats the movement of returning to the center line.

  A typical elderly driver is usually unable to drive straight, and always moves to the right, returns to the center line, returns to the center line, and returns to the center line. Even if the Chuo Line is crossed, the driver is conscious that the car will not hit if an oncoming vehicle does not come. Also, sometimes a large truck comes in and is surprised to turn left and hit left. Therefore, a specific place where such a driving is likely to be performed is preferably a “position where danger is predicted”.

  On the other hand, the “danger unique to an elderly driver” may be a risk possessed by a particular elderly driver, and may be set by the family of the elderly driver. For example, in a convenience store where a specific elderly driver goes on a daily basis or a home center that is regularly visited, and where there are many people or vehicles coming in and out, it is assumed that danger is expected. It is recommended that the family sets the “location information that is predicted”.

  In addition, for example, a place where an accident has occurred before may be set by the family as a “position where danger is predicted”. For example, if the accident is a mistake in the accelerator and brake, It may be set as an example related to “location information where a danger peculiar to a person is predicted”.

  (4) For example, regarding the event information in which the elderly driver can become a perpetrator of an accident by driving the vehicle, the situation information is related to the position information, and a risk specific to the elderly driver is predicted. It is good to have a function set by the family of the elderly driver.

  In this way, it is possible to comprehensively set a situation where an elderly driver's family can be a perpetrator specific to an elderly driver based on limited position information and event information corresponding to the position. . Accordingly, since the warning is comprehensively notified at the position and the event where the elderly driver is likely to be the perpetrator, the family can drive the elderly driver with more peace of mind. In addition, since the driving range of an elderly driver is limited, an event in which danger is predicted in the driving range is also limited, and it is particularly preferable that the family has a function of setting location information.

  The “event information related to the position information and for which a risk specific to the elderly driver is predicted” may be, for example, information on the time, content, and weather of the event related to the position. Specifically, for example, when there is a school road for an elementary school student in the driving range of an elderly driver, the information may be related to the location information of the school road and information related to an event that the primary school student attends school in a predetermined time zone.

  There are countless places in Japan where tragic car accidents such as school roads can occur, but as long as it is limited to the driving range of older drivers, location information and event information can be narrowed to the extent that they can be set. However, it is not a big burden even if it is set for the elderly driver, and the family makes the setting for the elderly driver, and the family can have the elderly driver drive more safely.

  (5) For example, an external setting device for setting the situation in the device in (4), comprising a display unit, map information, the position information on the map, and before the position information Event information and warning information related to the content of the warning are displayed on the display unit, and the family of the elderly driver knows the situation where the elderly driver can become a perpetrator of an accident by driving the vehicle. It may have a function to set.

  In this way, information such as map information, position information, event information, warning information, etc. is displayed on the display means of the external setting device, and the situation where the elderly driver can be a perpetrator can be determined by the external setting device. Can be set. Since information such as map information can be set more easily if it is displayed larger, each setting is facilitated if it can be displayed on a display device of an external setting device different from the device that can be attached to the vehicle as in the present invention. .

  For example, the external setting device may be a personal computer, a tablet, a smartphone, or the like. Alternatively, the connection to the external setting device may be performed via, for example, wired or wireless, or may be performed via a storage medium such as an SD card.

  The “setting function” of the external setting device, for example, sets each setting by the external setting device on behalf of this device, instead of the setting unit of this device, for the predetermined conditions stored in the storage means of this device. It is good to have a function to do. For example, this device may be connected to the external setting device by wire or wirelessly and have a function of setting conditions for determining the situation by the external setting device.

  The external setting device enables selection of the condition while looking at the display unit of the external device, and creates setting data as a condition for determining suitability of the situation. Thereafter, the setting data may be stored in the storage unit of the device as the condition. If the device can be connected to such an external setting device, for example, the device according to the present invention may be provided with only a connection unit to the external setting device and no setting unit such as a button. . In this way, the structure of the device can be simplified.

  The “map information” is, for example, an electronic map and may be displayed on a part of the display screen of the display unit. Further, the “location information on the map” may be displayed on the map as, for example, pins arranged at predetermined positions in the displayed map.

  “Warning information” is, for example, a warning that is displayed on the display screen of the device in (13), which will be described later, or is generated by a warning sound output means, and which notification means notifies the warning by any method. It is good to use this information. Specifically, the “warning information” is notified by, for example, information indicating that the warning is notified by a single color background and large characters on the display screen, a beep sound, or a recorded family voice. It may be information indicating that

  (6) For example, further comprising a position information registration unit for registering the position information, when the elderly driver's family drives the vehicle driven by the elderly driver on behalf of the elderly driver, The position information registration unit may be operated to register the position information.

  In this way, the elderly driver's family is driving on behalf of the elderly driver, and only the dangerous position is registered assuming that the elderly driver will drive. Other information can be registered.

  The other information may be information such as whether the position is in a poor visibility field, a traffic light at the position, or whether the position is an elementary school route. By doing so, it becomes easy to register position information based on actual driving. Therefore, the task of setting the situation becomes easy, the dangerous position can be surely registered, and the possibility that an elderly driver will have an accident can be reduced.

  Further, the external setting device of (5) may be configured such that an elderly driver's family can set together with the elderly driver. For example, the elderly driver's family drives the location information by the location information registration unit. After registering the location information, the elderly driver can set the situation that can be a perpetrator of the accident by driving the vehicle together with the elderly driver. We can expect improvement of communication with.

  The “position information registration unit” may be a pressing unit such as a button or a touch panel provided on the device. By doing so, since the pressing means can be easily pressed even during driving, the position information can be appropriately registered on the spot.

  Further, the “position information registration unit” may be provided in an external registration unit such as a remote controller connected wirelessly or by wire. By doing so, it is possible to arrange the remote control within the reach of the driver, so that the driver does not need to reach out to the device and can register the position information without changing the posture during driving.

  (7) For example, the warning notification may be started after the elderly driver becomes a situation that can be a perpetrator of an accident, and the notification may be terminated after a situation that cannot be a perpetrator of the accident.

  In this way, older drivers can recognize the accuracy of their driving by ending the notification after becoming a situation that can not be perpetrators, and continue notification even in situations that can not be perpetrators Compared with the case where it ends, it comes to be able to keep proper driving in mind.

  The “situation in which an accident cannot be perpetrated” may be a situation in which there is no possibility of becoming a perpetrator, for example. The “situation in which there is no possibility of becoming a perpetrator” may be, for example, when the moving speed of the vehicle becomes 0 km / h (when the vehicle stops). Alternatively, the “situation where the person cannot become the perpetrator of the accident” may be a situation where there is no possibility of becoming a perpetrator.

  If notification ends normally when there is no possibility of becoming a perpetrator, notification ends normally when notification is considered unnecessary, and notification ends only when there is no possibility of becoming a perpetrator Compared to the above, older drivers can recognize the accuracy of their driving more appropriately.

  The “situation that can be the perpetrator of the accident” may be a fixed condition, for example. In general, for example, the situation in which an elderly driver can be the perpetrator of an accident is wider than the situation in which a normal driver other than an elderly driver can be the perpetrator of an accident. Possible situations include situations in which a normal driver other than an elderly driver can be a perpetrator of an accident. Therefore, the “situation where an elderly driver can be an offender of an accident” should be initially set in a wider range than a situation where a general driver can be an offender of an accident.

  In addition, the “situation where the person cannot be the perpetrator of the accident” may be a fixed condition, for example. In general, for example, the situation in which an elderly driver cannot be the perpetrator of an accident is narrower than the situation in which a normal driver other than an elderly driver cannot be the perpetrator of an accident. The situation where the driver cannot become a driver is included in the situation where a normal driver other than an elderly driver cannot be a perpetrator of the accident. Therefore, for example, the “situation in which an accident can not be a perpetrator” may be initially set in a narrower range than a situation in which a general driver can be a perpetrator of an accident.

  Also, for example, at least one of “a situation where an elderly driver can be a perpetrator of an accident” and “a situation where an elderly driver cannot be a perpetrator of an accident” is set as an initial setting, or as in (2) It is recommended that the family of the elderly driver be set.

  In particular, for example, a family of the elderly driver may set both “a situation where an elderly driver can be a perpetrator of an accident” and “a situation where an elderly driver cannot be a perpetrator of an accident”. . If it does in this way, it can urge the elderly driver to do the suitable driving according to his / her characteristic by having a family set up.

  Further, for example, the family may set only the “situation where an elderly driver can be a perpetrator of an accident” without setting the “situation where an elderly driver cannot be the perpetrator of an accident”. By doing so, the situation in which the notification is terminated is left to the initial setting, and only the situation in which the notification is started is set by the family, so that the warning is surely notified in a situation specific to the elderly driver while facilitating the setting. can do.

  (8) For example, the traffic light information on the color of the traffic light in front of the vehicle and the speed information on the speed of the vehicle are acquired, and the elderly driver drives the vehicle from the traffic signal information and the speed information. To determine whether or not the situation can be a perpetrator of the accident.

  If it does in this way, the possibility of the accident which occurs frequently in an elderly driver can be reduced by determining as a situation where an elderly driver becomes a perpetrator from the relation between traffic signal information and speed information. In addition, an elderly driver is likely to be mistaken for driving because of a decrease in the degree of concentration due to aging and other attention being easily taken during driving, and to be a perpetrator of an accident. For this reason, there are many cases in which a traffic light is overlooked due to these causes, or it is delayed to notice.

  For example, when the color of the traffic light in front of the vehicle is red or yellow and the vehicle speed does not decrease, the notification means may notify the warning. By doing so, it is possible to reduce the possibility of an accident in which the elderly driver is not good, such as entering an intersection to be stopped and colliding with another vehicle.

  Further, for example, a warning that prompts the start of the vehicle may be issued when the moving speed of the vehicle does not change even if the color of the traffic light changes from red to blue. In this way, it is possible to prevent a driver from mistakenly trying to start the vehicle when he / she notices that the color of the traffic light has turned blue.

  In particular, older drivers tend to be more timid as they get older, which can be frustrating when horns are sounded. Then, even if there is no accident on the spot, driving in an irritating and unstable mental state can cause an accident in another place. Therefore, if the start is notified by a green light, the horn from another vehicle is not sounded, and the annoyance of the elderly driver can be suppressed.

  The “signal information” may be acquired by, for example, an imaging unit such as a camera that images the front of the vehicle. The traffic signal information can be acquired by recognizing the traffic signal and grasping the color with the key that the LED of the traffic signal blinks innumerably when the image captured by the imaging means is processed.

  The “speed information” can be acquired based on a speed that can be acquired from GPS or OBD or acceleration by an acceleration sensor, and may be information on the speed or acceleration of the vehicle.

  Further, at this time, it is preferable to further include the configuration (7). For example, based on the traffic signal information and the speed information, a warning notification is given when an elderly driver becomes a perpetrator of an accident. The notification should be terminated when it becomes impossible to become the perpetrator of the accident.

  In this case, for example, the traffic signal information is a red signal and the speed information is a predetermined signal by terminating the notification in a situation where the elderly driver cannot be the perpetrator of the accident based on the traffic signal information and the speed information. When the moving speed is higher than the moving speed, the notification is started, and when the moving speed of the speed information is less than or equal to the predetermined moving speed in relation to the distance to the traffic light, the old driver can It can be recognized that the signal is properly handled.

  If the notification continues for a while even if the moving speed falls below the predetermined value, it is easy for the elderly driver to feel as if he / she has decelerated. Therefore, the effect of properly terminating the warning notification is great.

  (9) For example, whether or not the vehicle information that the elderly driver drives is determined to be wobbling based on the vehicle information, and based on the determination, the elderly driver can become a perpetrator of the accident by driving the vehicle. It may have a function of determining whether or not.

  Since the driving of elderly drivers generally has the characteristic that they are likely to wobble from side to side, in this way, warnings are reported in situations where elderly drivers become perpetrators based on wandering. The possibility of accidents that occur frequently in elderly drivers can be reduced by the wobbling driving that is characteristic of elderly drivers.

  “Fluctuation” is, for example, a state in which the traveling vehicle has moved to the right side as described in (10) below, in addition to the so-called wobbling state where the traveling vehicle moves in an unstable manner to the left or right, or left It is good to make it the state which changed greatly to one of these, and it is good to judge from vehicle information. The vehicle information used for the determination of “fluctuation” may be acquired, for example, by a change in left and right accelerations using an acceleration sensor. Moreover, it is good to acquire by the change of the positional information acquired by GPS. Moreover, it is good to acquire from the image image | photographed with imaging | photography means like a camera.

  “Fluctuation” may be caused by, for example, a situation that arises from a driving habit peculiar to an elderly driver who repeats the movement of returning to the center line, or a situation caused by a narrow visual field peculiar to an elderly driver. Good. Further, it is preferable not to distinguish between wobbling and bending. For example, it is better to determine that wobbling is uniform when the vehicle information matches a predetermined condition for wobbling.

  In addition to the left and right wobbling, the “stabilization determination” may be performed by determining wobbling due to changes in the speed and acceleration of the vehicle, such as sudden start and sudden braking, and warnings about sudden start and sudden braking. It is good to inform.

  (10) For example, it is determined from the vehicle information that the vehicle has shifted to the right by a predetermined value or more, and based on the determination, the elderly driver can become a perpetrator of an accident by driving the vehicle. It is good to determine whether or not.

  In this way, it is possible to reduce the possibility that a serious accident such as a frontal collision will occur when the vehicle approaches the right side and an oncoming vehicle comes.

  For example, an elderly driver often moves toward the center line and returns. This is a driver's peculiar to elderly drivers who have a guard rail on the left side, but are alert on the left side, but on the right side there is no danger if an oncoming vehicle does not come even if it crosses the center line. However, if the vehicle approaches the right side, a serious accident such as a frontal collision will occur if an oncoming vehicle comes.

  Therefore, it is possible to reduce the occurrence of a serious accident peculiar to an elderly driver by notifying the warning when the change in the right direction is large in the wobble information. Also, for example, a warning may be notified when the state has changed greatly to the left. By doing so, it is possible to notify the elderly driver that there is a possibility that there are pedestrians and bicycles in the traveling direction.

  The determination that “the vehicle has shifted to the right by a predetermined value or more” may be performed based on, for example, that the vehicle has straddled the center line or that the distance from the center line has decreased.

  (11) Further, it is determined whether or not there is an oncoming vehicle, and from the determination that the vehicle has shifted to the right by a predetermined value or more, whether or not the elderly driver can be a perpetrator of an accident by driving the vehicle Even if it is determined that there is no oncoming vehicle, a warning is not notified.

  Even if the driver is driving to the right side due to the characteristics of driving by an elderly driver, if there is no oncoming vehicle, there is little possibility of causing a serious accident. Therefore, if the notification is performed every time when the user frequently goes to the right, the elderly driver may feel uncomfortable. Therefore, when the oncoming vehicle does not come, the warning is not notified, so that the notification is not repeated and it is possible to reduce the driver from feeling uncomfortable.

  The oncoming vehicle information can be acquired based on whether or not the image of the vehicle viewed from the front direction is included in an image captured by an imaging unit such as a camera.

  (12) For example, a situation in which climate information is acquired in addition to the vehicle information, and the elderly driver can become a perpetrator of an accident by driving the vehicle based on the climate information together with the vehicle information. It is good to determine whether or not.

  In this way, it is possible to notify a warning based on the climate information related to the position of the vehicle, and to reduce the danger of elderly driving due to the climate. In general, an elderly driver is likely to suffer from a bad condition due to the climate. Therefore, compared with an ordinary driver, a risk unique to the elderly driver is likely to occur due to the climate during driving.

  Therefore, when a warning is issued to the vehicle information and the general driver based on the climate, the warning may be notified at a stage that is severer and quicker than the condition that the general driver is assumed to be dangerous. In addition, although the structure which uses climate information with vehicle information is described at the time of this-application application, it replaces vehicle information and has the intention to make rights by dividing | segmenting etc. the structure which uses climate information.

  The “climate information” may be information about the physical state in the atmosphere or the atmosphere such as temperature, humidity, clear rain, and wind speed. For example, the control means may be various sensors such as a temperature sensor, a humidity sensor, and a wind speed sensor. In addition to directly acquiring the information, the fact that the wiper has operated may be acquired via the OBD connector, and the rainfall information may be acquired indirectly.

  The vehicle information may be vehicle position information, for example. In this way, it is possible to comprehensively set a situation in which an elderly driver's family can be a perpetrator specific to an elderly driver based on limited location information and climate information corresponding to the location. Accordingly, since the warning is comprehensively notified according to the position and the climate where the elderly driver is likely to be a perpetrator, the family can drive the elderly driver more safely. Since an elderly driver has a limited driving range, position information is limited from the driving range.

  For example, when the temperature is high enough to predict the risk of heat stroke, etc., the warning is issued based on the climate information and the position information. A warning that prompts replenishment may be notified. Thereby, it is possible to reduce the possibility of an accident in which an elderly driver accidentally becomes a perpetrator due to heat stroke.

  In addition, “notifying a warning based on climate information” is, for example, a warning, for example, a notification that prompts hydration in the summer when the temperature in the summer becomes high or when the temperature inside the vehicle rapidly increases. Good. Since many elderly people are tolerant of climate change, warnings can be issued based on climate information, allowing older drivers to recognize climate changes and deterring the risks inherent to older drivers. .

  Warning alerts do not strongly limit actions. For example, as advised, it is better to drink water, open windows, or to call attention. It should be something like a boost. Further, the warning to be notified may be a notification such as “If you drive for a long period of time, your concentration will be reduced” or a notification such as “It is difficult to see the front” when it rains.

  (13) For example, the notification means may include a display screen capable of displaying a single-color background on the entire surface, and the display screen may notify a warning by changing the color of the background.

  In this way, a change in color, which is visual information that is most easily recognized by an elderly driver, is reported as a single color change particularly in the background of the entire display screen where the change is easy to recognize. As a result, the warning can be surely recognized by the elderly driver, so that the probability of an accident caused by the driving of the elderly driver is reduced, and the family can drive the elderly driver with peace of mind.

  The “color change” may be changed from a state in which the display screen normally displays an image such as a camera image to red. This makes it easier for the elderly driver to understand that the state is different from the normal state compared to a change to a color other than red, and can reduce the probability of an accident caused by the driving of the elderly driver. . The “color change” may be a change in which the background of the same color blinks or a change in which the backgrounds of different colors are sequentially replaced.

  For example, even for an elderly driver who is driving with various visual acuity diseases such as cataracts, the change in the color of the display background is most easily recognized intuitively compared to the warning by text. By memorizing that the danger is notified by the color, the possibility of becoming a perpetrator of the accident is reduced.

  (14) For example, the notification means includes a warning sound output means for notifying the warning by sound, and the display screen displays a warning by characters in addition to the display background, according to the characteristics of the elderly driver, A warning may be notified by the notification means based on a combination of the color of the display background and at least one of the character and the sound.

  In this way, it is easy for an elderly driver to recognize the warning by notifying the warning by a combination of at least one of characters and sounds in addition to the color of the display background. In particular, an elderly driver may have a physical problem. In such a case, even if it is difficult to recognize the warning by one method, the elderly driver can recognize the warning.

  For example, the display screen may have a configuration that does not include elements other than the background and characters. For example, the display screen may have a function of notifying an alert only with characters and background colors without displaying an icon or a map. Further, for example, the red color may be set to a color that is easy for an elderly driver to recognize.

  For example, an elderly driver who has a problem in visual acuity may have difficulty in recognizing characters, but if a warning with the color or sound of the display background is given together, the warning can be recognized properly. In addition, an elderly driver who has a problem with hearing ability can recognize a warning appropriately if the warning with the color of the display background or characters is performed together. Moreover, even if it is difficult to recognize characters during driving, the characters can be recognized if the vehicle is stopped.

  (15) For example, at least one of the color of the display background, the characters, and the sound may be set by the family of the elderly driver according to the characteristics of the elderly driver.

  In this way, the family who knows the elderly driver best can set the display according to the characteristics of the elderly driver, and can notify the warning that is most easily recognized. As a result, the elderly driver can drive the vehicle under the love of the family, and the awareness of trying to prevent an accident is increased.

  As a setting method, for example, a plurality of combinations of the display background color and the character color may be prepared by the initial setting, and only the content of the warning text by the characters may be changed. By doing so, it is possible to individually set the contents to be alerted with easy-to-see color combinations according to the characteristics of the elderly driver.

  The color combination may be, for example, a complementary color relationship, but may be further selected according to the personality of the elderly driver. In addition, for example, a voice of a family member such as “Be careful about grandpa” may be recorded and notified according to the situation. If it ’s a family voice, the elderly driver can accept the alert.

  By the way, for example, reward information that may give motivation to drive an elderly driver based on the distance or frequency at which the vehicle is driven may be displayed on the display means. In particular, as in the following (16), for example, the frequency of driving may be measured by counting the number of days the vehicle has been driven.

  (16) For example, when the number of days that the vehicle has been continuously driven is counted, and the predetermined number of days is counted, reward information that can give the driver a motivation to drive may be displayed on the display means.

  The reward information is displayed according to the number of days that the elderly driver has continued to drive the vehicle, so that the elderly driver can be motivated to drive and be motivated to drive even every day. Thereby, an elderly driver does not dislike driving and is not withdrawn, and an environment in which an elderly driver can safely drive an elderly driver can be provided.

  “Counting the number of days” is not a simple driving distance, number of times, or frequency, but may be, for example, counting days that have been driven even once in a day. In addition, when “a predetermined number of days is counted”, for example, it may be counted that the vehicle has been driven every day during a predetermined period such as one month. Specifically, for example, if it is possible to drive safely for 10 days, it is preferable to display an image such as an egg hatching and an animal appearing on the display device of the device.

  Furthermore, for example, if you can drive safely in the next 10 days, it is better to increase the number of animals that hatch from eggs. In that way, coupled with the desire to collect animals, the elderly can be motivated to drive every day. The driving day may be counted based on, for example, that the vehicle engine is started. Or it is good to count on the basis that the vehicle moved a predetermined distance.

  The “reward information” may be, for example, a photographic image of an elderly driver's family in addition to an animal image. Older drivers have a deep affection for their families, so doing so can increase the motivation to drive with reward information. For example, the reward information may be displayed at any time according to the number of days for which driving is continued, and the reward information may be further changed according to the number of days continued. When the reward information is changed, for example, the reward information may be changed so as to increase the value of the reward. The number of days for which the operation is continued when the reward information is displayed may be two or more days, but may be several days, particularly five days. Moreover, although the said number of days may be 5 days or more, since it may stop driving | running in the middle when it is too long, it is still more preferable to set it around 2 to 5 days.

  In addition, for example, the reward information may be displayed without performing the deduction process for the frequency of driving the vehicle. By doing so, the deduction points do not prevent the elderly driver from driving, and the motivation to drive based on reward information is not hindered. For example, even if a sudden start, sudden braking, etc. are acquired from information from an acceleration sensor during driving, or even if the driving distance does not reach the predetermined distance scheduled for normal driving, Count the days you drove without waking up. In particular, when the frequency with which the vehicle is driven is counted as the number of days as described above (16), the following (17) is preferable.

  (17) For example, the count may only be added.

  If the day count may be subtracted, it may reduce the motivation for the older driver to continue driving every day, but since the day count is only added, the older driver simply You only have to think about driving and you can keep driving every day. As a result, it is possible to provide an environment where the elderly driver's family can safely drive the elderly driver.

  Further, the number or frequency of driving of the vehicle is calculated, and when the calculated value is equal to or greater than a predetermined value, reward information that can give motivation for driving to the elderly driver is displayed on the display means. It is better not to subtract.

  In this way, the driver's motivation to drive can be enhanced by notifying only good information but not bad information.

  (18) It is good to comprise as a program for making a computer perform the function of the apparatus in any one of (1)-(17).

  The above-described configuration is an example, and a part thereof may be expanded or a part thereof may be limited. Further, the configurations may be combined within a range where there is no contradiction in the configuration. For example, the above-described inventions (1) to (17) can be arbitrarily combined. Further, for example, it is possible to provide at least one of the configurations (2) to (17) without including all or part of the configuration (1). However, in particular, all or part of the configuration of (1) may be provided, and at least one of the configurations and combinations of (2) to (17) may be provided.

  [Notification of warning about traffic lights]

  A case will be described in which it is determined whether an elderly driver can become a perpetrator of an accident by driving a vehicle based on traffic signal information and speed information, and a warning is notified to a notification unit based on the determination. .

  In the safety system, the front view camera 11 captures the front of the vehicle, the control means 10 recognizes the LED traffic light from the captured image information, and acquires the information on the color of the traffic light as the traffic signal information. The control unit 10 of the main unit 1 acquires vehicle speed information from the OBD connector 13 and acquires acceleration information in the front-rear direction from the acceleration sensor 14. Here, the vehicle speed information and the acceleration information are included in the speed information related to the speed of the vehicle.

  From these traffic signal information and speed information, the control means 10 determines whether or not an elderly driver can be a perpetrator by driving the vehicle. Specifically, the traffic signal information conforms to the condition that the color of the traffic light is red or yellow, the speed information is equal to or higher than a predetermined speed such as 10 km / h, and the vehicle is decelerated. If the condition is not met, the elderly driver may not be aware of the red traffic light. Therefore, it is determined that the elderly driver can be a perpetrator by entering the intersection at the red traffic light.

  And when it determines with the situation where an elderly driver can be a perpetrator, a display part is shown in FIG.4 (B) and (C) from the driving | running | working screen which image | photographed the vehicle front, as shown to FIG. 4 (A). As shown in Fig. 4, the screen is switched to a notification screen for notifying a warning. On the notification screen, the characters 41 “watch out for the signal” are displayed in white, and the background 42 is a background color of only red (displayed in gray in FIG. 4B) and a background color of only black (FIG. 4). (See (C)). Further, the speaker 22 is notified as a warning with a sound that gives a soft impression of the message “Be careful with the signal”.

  In this way, using the result of the main body determining the blinking caused by the power of the LED traffic light as a key, the recognition of the red signal and the speed of the vehicle, for example, the moving speed, and the speed change, for example, acceleration / deceleration are recognized. If the acceleration doesn't decrease much, you can let us know in advance that you should stop immediately because it is a red light.

  Further, the control means 10 recognizes the distance from the image information to the traffic signal that is the basis of the traffic signal information, and ends the warning notification according to the distance and the speed information. Specifically, it cannot be a perpetrator of an accident if the vehicle decelerates below the speed assumed to be able to stop at the stop position corresponding to the traffic signal and the actual vehicle speed meets the conditions. It is determined that the situation has been reached and the notification is terminated.

  [Notification of warnings regarding wandering, etc.]

  It is determined from the vehicle information that the vehicle driven by the elderly driver has deviated more than a predetermined value to the right in the lane, and whether or not the elderly driver can become a perpetrator of the accident by driving the vehicle based on the determination. A case will be described in which a warning is notified to the notification means based on the determination.

  As shown in FIG. 5, when a vehicle C driven by an elderly driver approaches the right side of the lane, in the vehicle, the acceleration sensor 14 detects acceleration in the left-right direction, and the acceleration information detected by the control means 10 is detected. To get. Further, the control means 10 acquires image information ahead of the vehicle from the front view camera 11 and recognizes the distance between the vehicle C and the center line L of the road. Thereby, the control means 10 determines from the acceleration information and the image information that the vehicle has shifted to the right by a predetermined value or more, and issues a warning based on the determination.

  Specifically, the vehicle C is shifted from the acceleration information to the right by a certain value or more and the interval between the vehicle C and the center line L is a certain value or less. When the behavior matches the condition, the control means 10 determines that the elderly driver can be a perpetrator.

  A certain value regarding the vehicle C approaching to the right and the distance between the vehicle C and the center line L is predetermined in the determination program of the control device. In the present embodiment, the constant value of the distance between the right end of the vehicle C and the center line L is set to 10 cm, but the constant value may be set to 0 or a negative number. However, in order to determine more safely that the elderly driver has approached the center line, the certain value may be set in the range of 5 cm to 50 cm. When it is determined that the elderly driver can become a perpetrator of the accident by driving the vehicle, the control unit 10 starts flashing the display of the display device 18 and notifies a warning.

  Elderly drivers tend to drive from the center of the lane to the right, return, go to the right, return to the left, and feel the danger when the oncoming vehicle comes. By notifying such wobbling peculiar to an elderly driver at the stage at the right, it is possible to determine a situation in which a general elderly driver can be a perpetrator.

  Next, from the vehicle information, it is determined whether or not the wobbling of the vehicle that the elderly driver is driving, and based on the determination, it is determined whether or not the elderly driver can be a perpetrator of the accident by driving the vehicle. A case will be described in which a warning unit is notified of a warning based on the determination.

  As shown in FIG. 6, when the vehicle C driven by the elderly driver fluctuates, in the vehicle C, the acceleration sensor 14 detects acceleration in the left-right direction, and the control means 10 acquires the detected acceleration information. Further, the control means 10 acquires image information ahead of the vehicle from the front view camera 11 and recognizes the distance between the vehicle C and the center line L of the road. Thereby, the control means 10 recognizes from the acceleration information and the image information that the vehicle C has moved to the right by a predetermined value or more and that the vehicle has moved to the left by a predetermined position or more.

  The control means 10 determines that the vehicle C is staggered when it is repeated that the vehicle C has shifted to the right by a predetermined value or more and the vehicle has shifted to the left by a predetermined position or more, and based on the determination. To alert you.

  Specifically, based on the image information acquired from the front view camera 11, the vehicle C is the center line L, the roadway outer line M, and the virtual line that is between the centerline L and the roadway outer line M shown in FIG. 6. The positional relationship with the intermediate line N is recognized. Then, from the acceleration information and the image information, the vehicle C has shifted to the right by a certain value or more, and the distance between the center of the vehicle C and the virtual intermediate line N has become a certain value or more in the right direction. It is recognized that C has shifted to the left by a certain value or more and the distance between the center of the vehicle C and the virtual intermediate line N has become a certain value or more in the left direction. Then, the control means moves on the left and right, with the predetermined condition that the distance between the center of the vehicle C and the virtual intermediate line N repeatedly exceeds a certain value on the left and right within a predetermined time. No. 10 is determined to be a situation where an elderly driver can be a perpetrator.

  A certain value when the vehicle C approaches the right is determined in advance in a determination program for operating the control means 10. In the present embodiment, the constant value when the vehicle C approaches the right is set to 50 cm as the distance between the center of the vehicle C and the virtual intermediate line N. In addition, the constant value when the vehicle C moves to the left is set to 50 cm as the distance between the center of the vehicle C and the virtual intermediate line N. The predetermined time for determining the wobbling is set to 30 seconds. These values can be changed as appropriate. When it is determined that the elderly driver can become a perpetrator of the accident by driving the vehicle, the control unit 10 starts flashing the display of the display device 18 and notifies a warning.

  Older drivers tend to drive from the center of the lane to the right to return and to the right to return. By notifying such wobbling peculiar to an elderly driver, it is possible to determine a situation in which a general elderly driver can be a perpetrator.

  Such determination of over-rightward movement or wobbling is incorporated in a determination program for operating the control means 10 according to a predetermined condition, that is, a predetermined value. Judgment is made on the basis of such a situation, and a situation in which an elderly driver can be a perpetrator is determined based on the determination and a warning is notified.

  [Notification of warning based on location information]

  Position information and event information related to the position are registered as a situation where an elderly driver can be a perpetrator of an accident. Thereafter, when a vehicle driven by an elderly driver arrives at the registered position, a warning is notified.

  The registration of the position information is performed from the viewer 71 as shown in FIG. 7 by the external setting device. Various types of information registered by the external setting device are stored as setting data in a memory card inserted into the external setting device. The memory card storing the setting data is inserted into the memory card slot 24 of the main unit 1. Then, the control unit 10 transfers the setting data from the memory card to the storage unit 25 of the main unit 1. Thereby, the storage means 25 of the main unit 1 stores the setting data.

  When the vehicle reaches a position corresponding to the position information of the setting data, the control means 10 displays related event information on the display means and makes a sound notification through the speaker 22 which is a warning sound output means.

  The PC of the external setting device displays a viewer 71 as shown in FIG. The viewer 71 displays map information 72, event information 73, and image information 74 taken by the front view camera 11 at specific positions of the map information 72. The map information 72, the event information 73, and the image information 74 are associated with each other. For example, a position 72a where the event information 72a is registered is displayed on the map. The image information 73 displays image information at the position indicated by the cursor on the map.

  The registration of the position information is performed by, for example, moving the cursor on the map and clicking at the position where the event information is to be registered. Event information is registered according to the menu at that position. By clicking the cursor at an arbitrary position on the map, event information at the position can be registered. The event information can register the event time, the notification target period, the direction in which the event occurs, the display content on the display unit, the background color of the display unit, and the like. Each item is configured so that it can be set by an option.

  In this way, for example, from Monday to Friday from 7 am to 9 am, registration is made on the condition that the target car, elementary school attendance, etc., and the elderly driver can drive in accordance with the registered conditions. If this happens, a warning can be notified, and an accident can be caused to an elementary school student who is attending school and the possibility of becoming a perpetrator can be reduced.

  [Notification of climate warning]

  In addition to vehicle information, weather information is acquired, and the determination of whether or not an elderly driver can become a perpetrator of an accident by driving a vehicle is explained based on weather information along with vehicle information To do.

  The control means 10 acquires temperature information and humidity information in the vehicle from the temperature / humidity sensor 16 as weather information. Moreover, the control means 10 acquires travel distance information from the OBD connector 13 as vehicle information. Thereby, the control means 10 determines from the vehicle information and the weather information whether or not it is a situation where an elderly driver can become a perpetrator of an accident by driving the vehicle. And if it determines with the situation where the elderly driver can become a perpetrator of an accident by driving a vehicle, the control means 10 will alert | report a warning to another apparatus.

  Specifically, the control is performed when the temperature information and the travel distance information meet the conditions, provided that the temperature in the vehicle has exceeded a certain value and the travel distance has become a certain distance or more. The means 10 determines that the elderly driver can be a perpetrator of the accident. The constant temperature and the mileage are initially set, but are set by a setting device according to the characteristics of the elderly driver by the family of the elderly driver.

  In this case, as shown in FIG. 8A, the control means 10 displays a character 81 “It is better to drink water because the temperature is high” on the display device 18. A similar warning is notified from the speaker 22 by voice.

  Moreover, the control means 10 acquires from the OBD connector 13 that the wiper has operated as weather information about rainfall. Moreover, the control means 10 acquires travel distance information from the OBD connector 13 as vehicle information. Thereby, the control means 10 determines from the vehicle information and the weather information whether or not it is a situation where an elderly driver can become a perpetrator of an accident by driving the vehicle. And if it determines with the situation where the elderly driver can become a perpetrator of an accident by driving a vehicle, the control means 10 will alert | report a warning to another apparatus.

  Specifically, on condition that the wiper has been operated and the mileage has reached a certain distance or more in that state, the control means 10 causes the elderly driver to accident due to rain. It is determined that the situation can be a perpetrator. The constant temperature and the mileage are initially set, but are set by a setting device according to the characteristics of the elderly driver by the family of the elderly driver.

  In this case, as shown in FIG. 8B, the control means 10 displays a character 82 “It is slippery because it rained” on the display of the display device 18. A similar warning is notified from the speaker 22 by voice.

[Display changes adapted to older drivers]
An example will be described in which the display issues a warning by changing the background color of a single color.

  The control means 10 notifies the warning by the warning information determined according to the situation where the elderly driver can be the perpetrator of the accident from the plurality of warning information stored in the storage means 25. For example, as shown in FIGS. 4B and 4C, the warning information is displayed in white with the words “careful of the signal”, and the background is a red-only background color and a black-only background color. A pattern that blinks alternately is used as a set of warning information. Therefore, the control means 10 determines one or a plurality of sets of warning information according to a situation where an elderly driver can be a perpetrator of an accident, and notifies the warning.

  The warning information is preferably set by the family of the elderly driver, and the family of the elderly driver can input the warning information by using the setting button and the touch panel 19 so that the display is suitable for the intended elderly driver. For example, the family of an elderly driver sets the content and color of characters to be displayed and the color of the display background according to the personality and preferences of the elderly driver.

  For example, when “warning display setting” is selected on the touch panel 19, the settings of items such as “character content”, “character color”, “background color”, and “flashing” can be set by the elderly driver's family. You will be guided to the display as you can. In the item “character content”, characters such as “careful of signals” can be input using the keyboard displayed on the touch panel 19. In the items “character color” and “background color”, colors such as red, blue, yellow, green, white, and black can be selected. In the “blinking” item, the presence / absence of blinking, the blinking interval, and the like can be selected. Each item is registered with a selection formula, and one warning pattern is set.

  [Continue safe driving for older drivers]

  A case will be described in which the number of days that the vehicle has been driven is counted, and when the predetermined number of days is counted, reward information that gives motivation for driving to an elderly driver is displayed on the display means.

  The control means 10 recognizes that the engine of the vehicle has started and counts the number of days that the vehicle has been driven. Specifically, the engine speed output is acquired via the OBD connector 13 to recognize that the engine has started. Then, the date and time when the engine is started is stored in the storage means 25. A predetermined number of days is counted from the date and time stored in the storage means 25.

  The control means 10 displays the reward information on the display means when counting a predetermined number of days. Specifically, the storage means 25 stores a plurality of reward information, and the control means 10 selects reward information corresponding to the number of days counted from the plurality of reward information, and displays the reward information on the display means.

  As shown in FIG. 9, in the reward information, on the first day when an elderly driver starts the engine, one day is counted and an egg image is displayed (FIG. 9A). Next, when the number of days is counted continuously for 5 days, an image of cracked eggs is displayed (FIG. 9B). Next, when the number of days is counted continuously for 10 days, an image in which an egg is broken and a chick appears is displayed (FIG. 9C). Next, when the number of days is counted continuously for 15 days, an image in which eggs hatch and chicks appear is displayed (FIG. 9D). Then, when the number of days is counted continuously for 20 days, a photograph of the family of the elderly driver is displayed together with a message (FIG. 9 (E)). Thus, the reward information may be image information that allows an animal to hatch from an egg and grow according to the counted number of days.

  In this way, the elderly driver is more motivated to continue driving while looking forward to the change in the image. If an elderly driver's family becomes too worried about becoming a perpetrator of an accident, the elderly driver can be prevented from being confined in the house.

[Modification]

  In this embodiment, based on the traffic signal information and the speed information, it is determined whether or not an elderly driver can become a perpetrator of an accident by driving the vehicle, and a warning is notified based on the determination result. In the above description, the position information is preferably taken into consideration in the situation determination.

  For example, in the case where the lane is curved and the signal cannot be recognized until immediately before, the control means 10 registers a position where the signal can be recognized, and acquires the traffic signal information after the vehicle reaches the position. Good. Specifically, when the vehicle reaches the registered position, the control unit 10 recognizes the target traffic light in the image information captured by the front view camera 11, and the color of the traffic light is red. It is good to make a warning when the acceleration sensor 14 or the vehicle speed does not change in spite of the fact that the color of the light is red.

  As another example of notifying the warning regarding the traffic signal information, when the color of the traffic light changes from red to blue, the start information may be notified. In this way, when an elderly driver is waiting for a signal and looking sideways, he will not be surprised to jump out of the horn from the following vehicle. Also, if you tell me the green light, you will know that you should proceed, you will not be surprised, and you do not need to be annoyed, so your heart rate does not increase and you can continue driving with a stable feeling.

  Older drivers generally tend to become more timid as they get older, so the effect of maintaining safe driving by preventing the heartbeat from increasing is great. The notification when the color changes to blue may be a blue background color with an image of “you can go” in the image of the notification screen. The “start information” is a function for notifying that the vehicle ahead is moving when the vehicle stops, and is also referred to as “stop and go”. Therefore, it is preferable to have a function of detecting that the preceding vehicle has started and notifying the driver.

  As for the timing of notification, it is better to notify the warning earlier than in the normal case of notifying a general driver of the warning. The timing of notification should be set by the elderly driver's family, and the elderly driver should drive once, set at a timing that seems to be good, and if the timing does not match the elderly driver, run again. Then, try setting again and again, such as setting again.

  The extension camera 15 acquires image information inside the vehicle centering on the elderly driver. The control means 10 acquires image information showing the elderly driver from the extension camera 15 and recognizes the driving state of the elderly driver. Based on this, the control means 10 may make a comprehensive determination from the images of the front view camera 11 and the additional camera 15 to notify the warning. For example, the elderly driver recognizes that the vehicle has approached the center line from the image information of the front view camera 11, and at this time, whether he was looking ahead or looking away from the image information of the additional camera 15 Recognize driving conditions. Based on these image information, if you stop by looking at the front, you will be alerted with a sound like "I'm going to the right", and if you are looking away, say "Look forward" The warning can be notified according to the situation, such as notifying the warning with such voice.

  In the present embodiment about warning notification regarding traffic lights, an example is shown in which a warning is notified when it is determined that an elderly driver can be a perpetrator, but the position or timing at which warning notification is started is For example, an elderly driver's family may be set individually. By doing so, the timing can be set according to the personality and preferences of the elderly driver who can know only because the family of the elderly driver is a family.

  The position or timing at which the warning is notified is, for example, when the control means 10 recognizes from 200 to 500 meters before the traffic light when the color of the traffic light is red, and the acceleration sensor 14 starts the warning notification. If it is determined that the vehicle has decelerated, it can be determined that the elderly driver is recognizing the traffic light, so the warning should be stopped.

  Here, if the warning is continuously reported until the vehicle speed reaches 0 km / h, it may harm the elderly driver who has already stepped on the brake and is stopping. Makes older drivers feel unstable and increases the risk of being a perpetrator of an accident. In the individual setting by the elderly driver's family, for example, the vehicle speed may be set so that the warning is terminated so that the numerical value before 200 to 500 meters is tuned and set.

  In addition, for example, in this embodiment, some situations are illustrated as situations where an elderly driver can be a perpetrator of an accident, but in addition, an accelerator that occurs at a specific position such as a parking lot of a convenience store It is assumed that there is a stepping error. For example, when the engine is started while the vehicle is stopped at a specific registered position such as a convenience store, an indication such as “departure safely” is notified, and the elderly driver starts stepping on the accelerator and the vehicle receives acceleration. Then, the control means 10 determines that the vehicle has started to move slowly, and after that, since it does not rush into the convenience store, it is preferable to end the display of “safe departure”.

  In the present embodiment, in the warning notification regarding the wobbling or the like, when determining the wobbling, the constant value when the vehicle C approaches the right, the constant value when the vehicle C approaches the left, the wobbling is determined. The predetermined time can be changed as appropriate. For example, a certain value serving as a reference for determining that the vehicle C has moved to the left or right may be obtained from the distance between the center line L and the roadway outer line M. For example, when the distance between the center line L and the roadway outer line M is 250 cm, 50 cm, which is a fifth value, may be set as a constant value when the vehicle C moves to the right. In addition, when the distance from the center line L is equal to or less than a certain value, it is determined that the vehicle has moved to the right. Therefore, it may be determined that it is staggered.

  Older drivers may return to the center line on the right and return to the center line, and may not normally drive straight. This is thought to be due to the awareness that “there is a fear because there is a guardrail on the left side, but if the other side does not come even if the center line is straddled, there will be no direct accident”. With such consciousness working, general elderly drivers basically go inside the road, sometimes suddenly hit a heavy truck and turn the steering wheel to the left, hit the left guardrail, accident May be a perpetrator. Assuming such a situation, when the vehicle moves to the right and changes significantly, you may be notified that the center line is not crossed? Arouse it. One possible cause of such wobbling is the narrow vision of elderly drivers.

  Moreover, although the example which alert | reports a warning when the vehicle C approaches the right was demonstrated using FIG. 5, it is good to alert | report a warning also in the following cases.

  First, when the state where the vehicle C has moved to the right continues for a certain period of time (situation 1), a warning is notified. Here, the state in which the vehicle C is shifted to the right is a state in which the distance between the right end of the vehicle C and the center line L is equal to or less than a certain value. For example, the fixed value may be 50 cm, for example, and the fixed time may be 30 seconds, for example.

  Next, when an oncoming vehicle comes from the opposite lane and the vehicle C approaches the left to avoid it (situation 2), a warning is notified. In this case, it is determined based on the image information of the front view camera 11 that an oncoming vehicle has come. Further, the fact that the vehicle has moved to the left may be a case where the distance between the right end of the vehicle C and the center line L is, for example, 150 cm or more.

  Next, when the oncoming vehicle disappears and the vehicle C approaches the right again (step 3), a warning is notified. It is determined from the image information of the front view camera 11 that the oncoming vehicle has disappeared. Further, the fact that the vehicle has moved to the right again may be when the distance between the right end of the vehicle C and the center line L is, for example, 50 cm or less.

  Furthermore, when the situations 1 to 3 are repeated several times (situation 4), a warning is notified. Moreover, it is good to alert | report a warning in the separate situation of the situation 1, the situation 2, the situation 3, and the situation 4. For example, the warning is not notified in the situation 1, the warning is notified in the situation 2, the warning is not notified in the situation 1 and the situation 2, the warning is given only in the situation 3, and the warning is given in the situation 2 and the situation 3. It is good to set so that the warning is notified in the situation 1 and the situation 4 without notifying. Whether the vehicle C has moved to the right or left may be determined by another method regardless of the relationship with the center line L.

  In the present embodiment, an example in which wobbling is determined and a warning is notified has been described. For example, when wobbling is determined only by acceleration information of the acceleration sensor 14, the wobbling is not a wobbling but a road with a continuous curve. When traveling along the road, driving similar to wobbling may be performed. In this case, it may be determined whether or not the light is wobbling. However, it is preferable to determine whether the light is wobbling or a curve without determining whether it is a light wobbling or a curve, and even if the curve is repeated.

  Or for example, it is good not to alert | report a warning uniformly as a forbidden area in the vicinity of an intersection. By doing so, by eliminating the vicinity of the intersection from the wobble determination, it is possible to reduce the notification of an unauthorized warning, and an elderly driver can concentrate on driving. If the family of the elderly driver makes such a setting, the elderly driver will be protected by the kindness of the family. Similarly, warnings should not be reported on sharp curves.

  In the present embodiment, the wobbling is determined based on the acceleration information in the left-right direction detected by the acceleration sensor 14, but it is preferable to determine a sudden start and a sudden brake based on the change in the acceleration information before and after and notify the warning. . By doing so, it is possible to determine whether the accelerator is stepped on too much or the brake is mistakenly pressed, and a warning can be notified.

  Further, in the present embodiment, the control unit 10 shows an example in which the vehicle wobble is recognized based on the image information in front of the vehicle from the front view camera 11 and the left and right acceleration information from the acceleration sensor 14. However, for example, the control unit 10 may recognize the vehicle wobbling only from the image information ahead of the vehicle from the front view camera 11. In other words, the control means 10 may recognize vehicle wobble from a single piece of information.

  Further, it is better that the control means 10 recognizes the wobbling from the GPS information, the steering wheel steering angle information, etc., and the wobbling of the vehicle is accurately determined by comprehensively judging the wobbling of the vehicle from the plurality of pieces of information. be able to.

  In this embodiment, an example is shown in which a warning about location information is notified. However, location information settings are known only to places where other people have previously had accidents, places where accidents often occur, and local people only. Enter the location where the accident is likely to occur and register in advance where the local residents are careful. Such position information may be shared via Internet communication, but may be set completely individually or individually. It is good to register with information only for a specific elderly driver, keeping the information of the main body alone.

  Therefore, it is better not to create a special site on the Internet so that information about the area can be entered, but the settings should be made individually by families such as sons of elderly drivers. . In addition, when a dealer of a vehicle buys a car from an elderly driver, it is preferable to register a position in which the person in the area is usually careful from the same standpoint as the family.

  The number of pieces of position information that can be registered is preferably limited to about 10. For example, an elderly driver often has a driving time of about 15 minutes or 20 minutes, and is not expected to drive for an hour. Although it is not daily, it is necessary to drive from time to time in hospitals, home centers, barbers, etc., but the place to go is still decided, and the distance from home is often about 5 to 10 km. Therefore, in many cases, the elderly driver has a limited action range, and can limit the position information that can be registered in the safety device.

  Therefore, in the safety device according to the present invention, the number (location) that can be set is limited, and a warning is notified when the location and time coincide repeatedly and repeatedly. For a general driver, enormous registration work is required to set the location and time, but in contrast, the elderly driver has a limited action range and action time. There is not much setting work.

  If individual setting is possible with an external setting machine such as a PC or a smartphone, setting from the main unit 1 or the display device 18 of the device becomes unnecessary. Therefore, the main unit 1 or the display device 18 can be configured not to have a setting button. For example, if the display device 18 is not provided with a setting button, the degree of freedom in design such as widening the screen can be increased.

  Notifying the warning is not limited to urgent attention, but it may be an advance notice such as registering a point near your home and saying "It's a little more" or "Be careful because it's a little more" . The event information may not be registered, and a warning may be notified based only on the position information.

  The registration of the position information is preferably performed jointly by the elderly driver and the family of the elderly driver. For example, even if an elderly driver is all right, if the dangerous driving is performed at a specific point while jointly checking the actual driving information, the elderly driver and his family have a common recognition Can have. Elderly drivers will provide all information such as where to go to their families and driving skills, but can strengthen their trust.

  In the present embodiment, the position information is registered by an external setting device. However, the position information may be registered by the position information registering means while driving, regardless of the external setting device. Specifically, the position information may be registered by pressing a button on the remote controller 17 corresponding to the position information registration means. For example, the position information is registered when the button on the remote controller 17 is pressed while driving, and after the driving is finished, this information is taken out to the external setting device, and the event information or the like may be set in the registered position information. By doing so, it is possible to create a highly accurate registration pattern by registering while driving a position where an elderly driver can be a perpetrator of an accident and adding information to the registered points.

  While the elderly driver's family is driving on behalf of the elderly driver, the location information is registered by the remote controller 17, and information is added or corrected to the registered location information together with the elderly driver. After that, it is recommended that the elderly driver actually drive. Furthermore, it is preferable to reset the information together with the family of the elderly driver while looking at the actual driving situation of the elderly driver.

  By repeating the setting work, the communication between the elderly driver and his family becomes dense. In accordance with this, it is further preferable that a warning notification method can be registered together for the registered position. When registering the position information while driving, the elderly driver may drive and the family registers the position information from the remote controller 17.

  In the present embodiment, an example has been described in which it is determined whether or not an elderly driver can become a perpetrator of an accident by driving a vehicle from the travel distance information and temperature information. For example, time information of GPS information Therefore, when the temperature condition continues for a certain period or more and the condition is met, the control means 10 may have a function of determining that the elderly driver can be a perpetrator. .

  In this way, it is possible to give some warnings such as notification that water must be replenished in summer when the temperature inside the vehicle suddenly rises or if the vehicle is driven for a long time. Older drivers are often mentally patient, for example, even in the house until they suffer from heat stroke. Therefore, it is useful to inform about climate information.

  When a warning is notified based on weather information, it is determined from the date and time by the temperature / humidity sensor 16 or the GPS unit 12 that the place is prone to heat stroke in the morning or in the daytime.

  When a warning is notified based on weather information, a warning may be notified by detecting a change in temperature after a predetermined time has elapsed after the engine is started. For example, a warning may be notified when the temperature has risen by a certain level or more than when going out only from the field work in summer. Further, for example, when going out in the morning and returning home at noon, a warning may be notified when the temperature difference is large.

  Even if the control device is in a situation where a warning is reported based on weather information, if a highly urgent event needs to be reported based on other information such as vehicle information, It is preferable not to perform warning notification based on information.

  In the setting of the position information, for example, a distance such as a field or a hospital where an elderly driver regularly goes from home may be set. Then, if it exceeds a certain distance, it is considered an unusual situation such as getting lost. In extraordinary situations, the temperature is often unnoticeable, and it has a great significance to notify a warning when the temperature is high again.

  In the present embodiment, the warning information displayed on the display is an example set by an elderly driver's family. As a premise of such setting, it is preferable that the color and character contents have one or more default warning patterns determined as initial settings. In addition, a warning pattern may be added by the family setting.

  For example, depending on the personality and preferences of the elderly driver, a strong tone of “careful” rather than “careful” may be suitable for the character content. The warning information displayed on the display may be configured so that a predetermined part can be arranged at an arbitrary position on the display, such as New Year's card creation software. You should write New Year and New Year on the upper right, and set it in the same way as the way you want to place the picture on the left side. Since many people experience such a setting once a year, the screen can be configured relatively easily. Then, it is recommended to have the elderly driver actually drive the vehicle and change the settings while trying. Change the highlighting of the background, blinking or lighting, etc. to find something that people can easily notice.

  In addition, the warning notification by characters is highly effective when stopped. For example, if the word “Be careful with the accelerator operation” appears at the moment when the parking lot is stopped at the convenience store and the engine is started, it is possible to prevent the accelerator from being stepped on. Moreover, there is a possibility that it becomes a habit to be careful every time by repeatedly informing the warning.

  For the warning notification by the display device 18, a plurality of registered patterns are stored in the storage means by initial setting. In this way, a registration pattern that can be easily recognized by an elderly driver may be registered by initial setting. Furthermore, it is preferable that the family of elderly drivers can use the default registration pattern by rewriting as a user. It is preferable to change only the character based on the registered pattern or to change only the combination of the character color and the background color. As a combination of colors, for example, there is a complementary color relationship.

  In addition to the warning by the display device 18, the warning may be notified by voice. For example, the control means 10 acquires voice information via the built-in microphone 21 and stores it in the storage means 25. The family registers the voice information as warning information corresponding to the situation. Thus, when a vehicle driven by an elderly driver is placed in a corresponding situation, a warning is notified by the voice information. Since it is difficult for an elderly driver to read characters while driving, warning notification by voice is effective.

  For example, the voice notification may be performed with a familiar voice of the son, the daughter, and the grandchild. In the present embodiment, the voice is stored in the storage means by the built-in microphone 21, but the voice data may be acquired by an external setting device and stored in the storage means of the main unit 1 via the SD card. Good. In addition to the voice, a beeping sound such as a beep sound may be used. However, it is easier to motivate an elderly driver to drive safely if a warning is issued so as to prompt the user with a gentle voice or sound.

  The sound can be set according to the elderly driver, but it may be said that it should be. Alternatively, the great grandchild's “dangerous” voice may be acquired by a smartphone application and stored in the storage unit of the main unit 1. The voice information is suitable for the target elderly driver, and the elderly driver is most careful. A sense of security may be given.

  In other words, it should be something that resonates with the mind of each elderly driver. It's a good idea to change the settings to discover which voices you don't know, simple sounds, the voices of people close to you, or the voices of your grandchildren or great-grandchildren you think are good. There may be cases where it is embarrassing to speak your own voice, or where sentences are better.

  The warning notification by voice may be performed once or repeated a plurality of times. If the old driver is frustrated and discomforted by the repeated notification, the notification may be made only once. As an initial setting, it is preferable that notification is made only once, and the setting is made to repeat a plurality of times by individual setting. A function for setting the number of repetitions and a notification period (for example, the number of seconds) may be provided. There should be a registration pattern for grandpa, grandma, gentle type grandpa, gentle people, and short-minded people. However, it is further preferable that such a registration pattern is set individually for a grandfather, assuming that only a specific elderly driver (for example, grandpa) drives.

  The text content should be a sentence or a message made by the grandchild of an elderly driver, for example, "Let's take care of him" or something like "Okaeri" when driving home. There should be. Even if something is not read while driving, the fact that the grandchild has set it will motivate older drivers to consider safety. By making individual settings rather than a notification method for everyone, it is possible to perform notifications that resonate with the elderly driver.

  For example, it is better to individually set whether the thickness of the character and the image of the character should be broken more, whether it should be softer or harder. There are some elderly drivers who can see the brighter one even if the color is the same red, while others that are really easy to see the dark red like wine red. While checking such things on an external setting device such as a personal computer, you can customize it while having a conversation about how easy it is to see.

  For example, if you have a physical illness or an eye illness and it is difficult to see a certain color, you could change the gradation of the viewer and display that used to use only a fixed color. It is good to provide as a PC viewer that can do it.

  In the present embodiment, a case has been described in which reward information is given so that one egg grows until safe driving continues for 20 days. After 20 days, the next egg is prepared and another egg is prepared. It is recommended that animals hatch. In that way, older drivers will be given the pleasure of collecting and collecting animals and will be more motivated to continue driving safely.

  In such a case, a distance target can be set with respect to the number of days, or points can be deducted when there is a sudden start or sudden stop based on the acceleration information of the acceleration sensor 14. However, in this case, the reward information is displayed for the elderly driver as a reward for being able to drive every day. If you do so, you will be encouraged to go out by driving aggressively setting goals or deducting points, etc., and the onset of illness due to withdrawal will be suppressed.

  In the present embodiment, an example of changing every 5 days has been described, but it is preferable to display a reward image that changes every day. The storage means may be a series of character images in which a plurality of character images are stored in the storage means and grows according to each stage of the number of acquired points. Specifically, if a character image of a plurality of stages is created with an image in which a larva becomes an adult after undergoing molting several times, for example, the user looks like a coupon to be acquired as a pet, Driving can be continued with the image of raising pets.

  Also, if you continue for 10 days, you can get one egg, and if you do it for another 10 days, it will hatch and you will be satisfied with your reward card on the screen. This will stimulate the collection habit and motivate older drivers to continue driving safely.

  The reward information provides an image on the screen that an elderly driver would be pleased with. Reward information should be of interest to older drivers, such as dog images, images, illustrations, cat images, animal series, world fish series, trains, grandchild photos, old photos, It should be a dinosaur, mountain, port, world heritage, etc. In particular, it should be something that arouses the collection habits of older drivers. In order to obtain such reward information, the elderly driver starts driving the vehicle every day and the state is maintained.

  The reward image may be set by the family. For example, it is preferable to prepare a plurality of photographs storing the growth of the grandchildren of the elderly driver and to display the photograph of the grown grandchildren as the counted number of days increases. By setting reward images for family members, it is possible to display images tailored to the preferences of older drivers, so reward images are initially set to motivate older drivers to continue driving safely. Compared to the case, it can be further increased.

  When setting the reward image, the external setting device may request a password known only to the family of the elderly driver. The reward image should be kept secret to the elderly driver as a little surprise to the elderly driver so that the elderly driver cannot view it. By doing so, the elderly driver cannot know what kind of reward image is registered, and can increase the motivation to continue driving safely in order to see the reward image.

  When an elderly driver drives the vehicle every day, the battery does not run up due to the engine operating every day, and the oil also rotates, leading to a reduction in failure. By doing so, it is possible to prevent the withdrawal of elderly drivers and reduce vehicle breakdowns by using only gasoline, and no unnecessary money is required.

  In the safety system, a situation where an elderly driver can become a perpetrator of an accident by driving the vehicle is set by the family of the elderly driver, and the family of the elderly driver matches the characteristics of the elderly driver. Warning information to notify the warning is set.

  With regard to the situation where an elderly driver can become a perpetrator of an accident by driving a vehicle, a condition serving as a criterion for determining the situation may be incorporated in the program of the control means 10 and stored in the storage means 25 as an initial setting. Or may be set by an elderly driver's family.

  The safety system is at least registered as a default setting for the initial setting. Without default settings, some settings must be made individually, which may be inconvenient for those who want to use them quickly. If the elderly driver can cope with the danger under the initial setting conditions, the initial setting can be used as it is. If the elderly driver cannot cope with the danger, the conditions can be individually set and added.

  In the initial setting, a warning is notified earlier than a general person in their 30s and 40s. For example, when the condition for notifying the warning is distance, the distance is 1.5 times and twice as much as usual. Individual settings are determined according to the personality and preferences of older drivers, whether they are aware of repeated notifications of “dangerous, dangerous” from 500 meters or 600 meters in front, or whether they can be known once. It is good to do.

  For example, there are some elderly drivers who are 65 to 80 years old, one of the targets of the safety system. If they are close to 65 years old, they can know by one notification, and if they are close to 80 years old, they need to be notified several times. First, once the elderly driver drives the vehicle, the traveling content is recorded together with the initial setting notification. For example, if the family confirms the recorded driving details and has not noticed the notification at all, try increasing the number of notifications or increasing the sound, such as notifying about twice more. It is better to make individual settings for notifications such as changing the color.

  According to the apparatus as described above, as illustrated in FIG. 2, the apparatus can be attached to a vehicle driven by an elderly driver, and the control means 10 of the apparatus includes vehicle information and traffic signals relating to the vehicle driven by the elderly driver. Information, climate information, etc. are obtained, and from this information, it is determined whether or not an elderly driver can become a perpetrator of an accident by driving the vehicle, and a warning is attached to the vehicle based on the determination. The display device 18 and the notification means such as the speaker 22 are provided with a function for informing. Therefore, in a situation where an elderly driver who drives a vehicle can be a perpetrator, a warning is notified to the elderly driver, thereby reducing the possibility that the elderly driver will be a perpetrator. However, it is possible to have older drivers drive with more peace of mind.

  The equipment that can be attached to the vehicle may be the main unit 1 that can be used by the elderly driver or his / her family attached to the vehicle driven by the elderly driver. It is good to have a structure that can be mounted on the dashboard of the car or on the top of the windshield.

  “Vehicle information about the vehicle” may be, for example, information acquired by the vehicle itself or information acquired by the device attached to the vehicle. For example, as vehicle information, external image information viewed from the inside of the vehicle or image information inside the vehicle, detection information detected by a detection device provided in the vehicle or a device attached to the vehicle, acquired by the GPS unit 12 It may be GPS information. For example, the image information may be acquired from a photographing apparatus such as the front view camera 11. The detection device may be a sensor such as the acceleration sensor 14, for example.

  “Determining whether or not an elderly driver can become a perpetrator of an accident by driving a vehicle from vehicle information” is determined by, for example, matching the acquired vehicle information with a predetermined condition Good. For example, the predetermined condition may be incorporated in a program for operating the control means 10 of the device according to the present invention or stored in the storage means 25 provided in the main unit 1.

  Therefore, “determining whether or not an elderly driver can become a perpetrator of an accident by driving a vehicle from the vehicle information” means that, for example, the control means 10 of the device according to the present invention includes a program. The built-in predetermined condition or the predetermined condition stored in the storage unit 25 may be compared with the acquired vehicle information to determine whether the information meets the condition.

  In addition, “the situation where an elderly driver can become a perpetrator of an accident by driving a vehicle” includes image information captured by the front view camera 11 or the additional camera 15, GPS information acquired from the GPS unit 12, OBD Although it is preferable to determine whether the single information such as the speed information acquired from the connector 13 matches a predetermined condition, it is better if it is determined that the plurality of information matches a predetermined condition. By determining conformity with a plurality of pieces of information, it is possible to qualify the “situation where an elderly driver can be a perpetrator of an accident” more appropriately than when determining conformity with a single piece of information.

  “Notify the warning based on the determination” means that, for example, when it is determined that a situation where an elderly driver can be a perpetrator of an accident meets a predetermined condition, the warning is displayed by blinking the display screen of the display device 18. It is good to process so that it may alert | report. Therefore, it is determined whether or not the situation of the vehicle is in conformity with a predetermined condition. If it is determined that the vehicle is in conformity, processing is performed so that a warning is issued. It is good to process.

  “Notifying a warning” may be, for example, a weaker warning compared to a general driver, and may be a warning that gives attention and gives advice. Do not make a strong beep. Since an older driver becomes shorter as he gets older, he should give a warning that will not surprise or frustrate.

  Furthermore, the device according to the present invention may have, for example, the above-described control as a control mode for an elderly driver and a control mode for a general driver other than the elderly driver. It is further preferable that both modes can be switched by 20.

  In the mode for a general driver, for example, a device that can be attached to a vehicle driven by a general driver other than an elderly driver, obtains vehicle information about the vehicle driven by the general driver, and acquires the vehicle information from the vehicle information. It is preferable to determine whether or not the general driver can be a victim of an accident by driving the vehicle, and to notify the notification means of a warning based on the determination.

  In addition, as shown in the present embodiment, it is preferable that the family of the elderly driver has a function of setting a situation where the elderly driver can become a perpetrator of the accident by driving the vehicle.

  In this way, if each elderly driver's family individually makes settings that are considered optimal for the elderly driver, an alert is issued in a situation that is considered optimal for the elderly driver. Compared to the case where the situation that can be a perpetrator of an accident is initially set, the anxious driver's anxiety is reduced, and the family can drive the driver more safely.

  The “function for setting the situation by the family of the elderly driver” may be a function for the family to set a part of a predetermined condition for determining conformity with the acquired information, for example. For example, a condition relating to the position of the vehicle may be set from the touch panel 19 or the input button 20 of the external setting device or the display device 18, or a condition relating to the color relating to the lighting of the traffic light and a condition relating to the speed may be set. The conditions set by the external setting device may be stored as setting data in the storage means of the device via a memory card. In particular, the condition relating to “position information” may be a position where the vehicle is placed or a predetermined range, and for example, a condition relating to speed may be a threshold value.

  Further, for example, as shown in FIG. 2, the device may include a display device 18, and the “function to be set” displays, for example, items set on the display device 18 of the device, and the touch panel 19 It is good to set it as the function set up by selecting an item suitably. For example, an item for setting a situation related to traffic light information and an item for setting a situation related to climate information are displayed on the display device 18. When an item related to climate information is selected, items such as temperature, weather, and humidity are displayed. When the temperature is selected, it is preferable to display such that the temperature at which the warning is notified is selected by the input button 20 in increments of 1 degree. The selection may be performed by a setting unit.

  Furthermore, this device may have a function that only the family can set, for example, a situation in which an elderly driver can become a perpetrator of an accident by driving a vehicle. It is good to have. For example, this device has a function of requesting a password, and it is preferable that a password is requested before setting, and that only a family member who knows the password can set by inputting the password with the touch panel 19, Older drivers who do not know the password should have a function that cannot be set.

  In addition, for example, a situation in which an elderly driver can become a perpetrator of an accident by driving the vehicle, the family of the elderly driver externally sets the position information on which a risk peculiar to the elderly driver is predicted. In addition, it may have a function to be set by the touch panel 19 or the input button 20 of the display device 18.

  In this way, since the warning is comprehensively notified at the position where the elderly driver is likely to be the perpetrator, the family can drive the elderly driver with more peace of mind. In addition, since the driving range of an elderly driver is limited, the position where danger is predicted is limited. Therefore, the family can set a unique position according to each elderly driver.

  The “danger unique to the elderly driver” is, for example, a danger common to ordinary elderly drivers, and may be a risk that focuses on the driving habits and driving habits of ordinary elderly drivers. For example, as shown in FIG. 6, the acceleration sensor 14 detects image information acquired by the front view camera 11 and driving information of a general elderly driver who repeats the movement of returning to the center line. The determination may be made based on the acceleration information in the left-right direction.

  A general elderly driver can not drive straight normally, and it is scary because there is a guardrail on the left side, moving right, going back to the center line, returning to the center line, Even though the Chuo Line is straddling, people tend to drive inward, with the consciousness that the car will not hit if the other side does not come. Also, sometimes a large truck comes in and is surprised to turn left and hit left. Therefore, a specific place where such a driving is likely to be performed is preferably a “position where danger is predicted”.

  On the other hand, the “danger unique to an elderly driver” may be a risk possessed by a particular elderly driver, and may be set by the family of the elderly driver. For example, in a convenience store where a specific elderly driver goes on a daily basis or a home center that is regularly visited, and where there are many people or vehicles coming in and out, it is assumed that danger is expected. It is recommended that the family is set together with the elderly driver by means of an external setting device as “position information that is predicted”.

  In addition, for example, a place where an accident has occurred before may be set by the family as a “position where danger is predicted”. For example, if the accident is a mistake in the accelerator and brake, It may be set as event information related to “location information where a danger peculiar to a person is predicted”.

  In addition, for example, the situation where the elderly driver can be a perpetrator of an accident by driving the vehicle is related to the position information, and the event information for which a risk peculiar to the elderly driver is predicted. It is desirable to have a function set by an elderly driver's family.

  In this way, it is possible to comprehensively set a situation where an elderly driver's family can be a perpetrator specific to the elderly driver based on limited position information and event information corresponding to the position. Accordingly, since the warning is comprehensively notified at the position and the event where the elderly driver is likely to be the perpetrator, the family can drive the elderly driver with more peace of mind. Since the driving range is limited for elderly drivers, there are also limited events for which danger is predicted in the driving range, and in particular, the family sets the number of position information items that can be displayed in the viewer shown in FIG. It is good to have the function to do.

  The “event information related to the position information and predicting the danger specific to the elderly driver” may be, for example, information on the time, content, and weather of the event related to the position. Specifically, for example, when there is a school road for elementary school students in the driving range of an elderly driver, the information about the event that an elementary school student attends school in a predetermined time zone is related to location information called school roads. The family may store in the storage means 25.

  Also, for example, an externally set device for setting the status of the device has a display unit such as a display like a personal computer or a smartphone, and includes map information, position information on the map, and events related to the position information. Information and warning information related to the content of the warning are displayed on the display device 18, and the family of the elderly driver has a function of setting a situation where the elderly driver can become a perpetrator of an accident by driving the vehicle. Good.

  In this way, information such as map information, position information, event information, and warning information is displayed on the display unit of the externally set device, and the situation where the elderly driver can be a perpetrator can be displayed. Can be set by user interface. Since information such as map information can be set more easily if it is displayed larger, as shown in FIG. 7, if it can be displayed on the display unit of an external setting device different from the device that can be attached to the vehicle as in the present invention, Each setting becomes easy.

  For example, the external setting device may be a personal computer, a tablet, a smartphone, or the like. Alternatively, the connection to the external setting device may be performed via wireless such as a wired or short-range wireless communication device 23, or may be performed via a storage medium such as an SD card.

  The “setting function” of the external setting device, for example, sets the conditions for judging the status stored in the storage means of the device, instead of using the setting unit of the device, and sets each setting to the external setting device. It is good to set the function according to. For example, this device is not provided with a setting unit such as the input button 20, and is connected to the external setting device by wire or wirelessly via the short-range wireless communication device 23, and a condition for determining the situation by the external setting device is set. The function to be set.

  The “map information” is, for example, an electronic map as shown in FIG. 7 and may be displayed on a part of the screen of the display unit. Further, the “location information on the map” may be displayed on the map as, for example, pins arranged at predetermined positions in the displayed map.

  “Warning information” is, for example, a warning that is displayed on the display screen of the display device 18 or is generated by a warning sound output unit, and information indicating which notification unit notifies the warning by which method. It is good to do. Specifically, for example, notification is given by a single color background on the display screen, information indicating that a warning is notified by a large character, a beep sound, or a family voice recorded by the built-in microphone 21. It may be information indicating

  Further, for example, the remote controller 17 of the device includes a position information registration unit for registering position information. When the elderly driver's family drives a vehicle driven by the elderly driver instead of the elderly driver, It is preferable that the information registration unit is pressed to have a function of registering position information. In this way, the elderly driver's family is driving on behalf of the elderly driver, and only the dangerous position is registered assuming that the elderly driver will drive. Other information can be registered.

  The other information may be information such as whether the position is in a poor visibility field, a traffic light at the position, or whether the position is an elementary school route. In this way, registration of position information based on actual driving is facilitated. Therefore, the task of setting the situation becomes easy, the dangerous position can be surely registered, and the possibility that an elderly driver will have an accident can be reduced.

  The external setting device may be configured so that an elderly driver's family can be set together with the elderly driver while watching the viewer shown in FIG. 7. For example, the position information registration unit can locate the elderly driver's family. Information can be registered while driving, and after registration of location information, the elderly driver can set up a situation that can be a perpetrator of the accident by driving the vehicle with the elderly driver. It can also be expected to improve communication with older drivers.

  The “position information registration unit” may be, for example, a button provided on the device or a pressing unit such as the touch panel 19. By doing so, since the pressing means can be easily pressed even during driving, the position information can be appropriately registered on the spot.

  Furthermore, the “position information registration unit” may be a button of an external registration unit such as the remote controller 17 connected wirelessly or by wire. By doing so, the remote controller 17 can be arranged within the reach of the driver, so that the driver does not need to reach out to the device and can register the position information without changing the posture during driving.

  For example, as shown in FIG. The warning notification may be started after the elderly driver becomes a situation that can become the perpetrator of the accident, and the notification may be terminated after the situation becomes impossible to become the perpetrator of the accident.

  In particular, for example, the “situation where an elderly driver can be a perpetrator of an accident” and the “situation where an elderly driver cannot be a perpetrator of an accident” are set externally as shown in FIG. It is better to set it by the device. If it does in this way, it can urge the elderly driver to do the suitable driving according to his / her characteristic by having a family set up.

  In addition, for example, the control means 10 acquires traffic signal information related to the color of the traffic light in front of the vehicle and speed information related to the speed of the vehicle, and the elderly driver drives the vehicle from the traffic signal information and the speed information. It is better to determine whether or not the situation can be a perpetrator of the accident.

  In this way, the control means 10 determines the situation where the elderly driver becomes the perpetrator from the relationship between the traffic signal information and the speed information, thereby reducing the possibility of accidents frequently occurring in the elderly driver. Can do. In addition, an elderly driver is likely to be mistaken for driving because of a decrease in the degree of concentration due to aging and other attention being easily taken during driving, and to be a perpetrator of an accident. For this reason, there are many cases in which a traffic light is overlooked due to these causes, or it is delayed to notice.

  For example, when the color of the traffic light in front of the vehicle acquired by the front view camera 11 is red or yellow and the vehicle speed does not decrease in the acceleration information detected by the acceleration sensor 14, the display device It is preferable that a notification means such as 18 or the speaker 22 notifies the warning. By doing so, it is possible to reduce the possibility of an accident in which the elderly driver is not good, such as entering an intersection to be stopped and colliding with another vehicle.

  The “traffic signal information” may be acquired by, for example, an imaging unit such as the front view camera 11 that images the front of the vehicle. The traffic signal information can be acquired by recognizing the traffic signal and grasping the color with the key that the LED of the traffic signal blinks innumerably when the image captured by the imaging means is processed. The “speed information” can be acquired based on the speed that can be acquired from the GPS unit 12 or the OBD connector 13 or the acceleration detected by the acceleration sensor 14, and may be information on the speed or acceleration of the vehicle. Also, at this time, for example, based on the traffic signal information and speed information, warning notification starts when an elderly driver can become an accident perpetrator, and cannot be the perpetrator of an accident. When the situation is reached, the notification should be terminated.

  In addition, for example, a situation in which the elderly driver drives the vehicle from the vehicle information such as acceleration information and image information, and based on the determination, the elderly driver can become a perpetrator of the accident by driving the vehicle. It is good to determine whether or not.

  “Fluctuation” is, for example, a state in which the traveling vehicle moves in an unstable manner to the left or right, a so-called wobbling state, a state in which the traveling direction has greatly changed to one of the right side, or a state in which the traveling direction has greatly changed to one of the left side. The control means 10 may determine from the vehicle information, and the vehicle information used for the determination of “fluctuation” includes, for example, a change in left and right acceleration by the acceleration sensor 14, a change in position information acquired by the GPS unit 12, and the front view camera 11. It is preferable to acquire a change in an image photographed by such photographing means.

  Further, the “determination of wobbling” is, for example, based on acceleration information detected by the acceleration sensor 14, in addition to left and right wobbling, for example, wobbling due to changes in the speed and acceleration of the vehicle, such as sudden start and sudden braking. And a warning about sudden start or sudden braking may be notified.

  Further, for example, it may be determined from the vehicle information that the vehicle has shifted to the right by a predetermined value or more, and from the determination, it may be determined whether or not an elderly driver can become a perpetrator of an accident by driving the vehicle. . In this way, as shown in FIG. 5, it is possible to reduce the possibility that a serious accident such as a frontal collision will occur when the vehicle approaches the right side and an oncoming vehicle comes. For example, an elderly driver often moves toward the center line and returns. This is a driver's peculiar to elderly drivers who guards the left side because there is a guardrail on the left side, but the right side is aware that there is no danger if an oncoming vehicle does not come even if it crosses the center line. However, if the vehicle approaches the right side, a serious accident such as a frontal collision will occur if an oncoming vehicle comes. Therefore, it is possible to reduce the occurrence of a serious accident peculiar to an elderly driver by notifying the warning by detecting that the acceleration sensor 14 has a large rightward change in the wobble information. For example, a warning may be notified when the acceleration sensor 14 detects that the change to the left is large. By doing so, it is possible to notify the elderly driver that there is a possibility that there are pedestrians and bicycles in the traveling direction.

  The determination that “the vehicle has moved to the right by a predetermined value or more” is made based on, for example, image information acquired by the front view camera 11 or the distance between the vehicle and the center line is reduced. It is good to make a decision based on this.

  Further, for example, the presence or absence of an oncoming vehicle is determined from the image information of the front view camera 11, and from the determination that the vehicle has shifted to the right by a predetermined value or more, the elderly driver drives the vehicle to the perpetrator of the accident. Even if it is determined whether or not the situation is likely to occur, if it is determined that there is no oncoming vehicle, processing may be performed so as not to notify the warning.

  Even if the driver is driving to the right side due to the characteristics of driving by an elderly driver, if there is no oncoming vehicle, there is little possibility of causing a serious accident. Therefore, if the notification is performed every time when the user frequently goes to the right, the elderly driver may feel uncomfortable. Therefore, when the oncoming vehicle does not come, the control means 10 does not notify the warning, so that the notification is not repeated and it is possible to reduce the driver from feeling uncomfortable.

  Further, for example, in addition to vehicle information, climate information detected by the temperature / humidity sensor 16 is acquired, and determination as to whether or not an elderly driver can become a perpetrator of an accident by driving the vehicle is performed together with the vehicle information. , Based on climate information.

  Therefore, when a warning is issued to the vehicle information and the general driver based on the climate, the warning may be notified at a stage that is severer and quicker than the condition that the general driver is assumed to be dangerous. The “climate information” may be information on the physical state in the atmosphere or the atmosphere such as temperature, humidity, clear rain, and wind speed. For example, the control means 10 may be a temperature / humidity sensor 16, a humidity sensor, or a wind speed sensor. In addition to acquiring directly from various sensors, it is preferable to acquire the rain information indirectly through the OBD connector 13 as the rain information that the wiper has operated.

  The vehicle information may be vehicle position information, for example. In this way, it is possible to set up with external setting devices, etc., covering the situation where the elderly driver's family can be a perpetrator specific to the elderly driver based on limited location information and climate information corresponding to that location can do. Accordingly, since the warning is comprehensively notified according to the position and the climate where the elderly driver is likely to be a perpetrator, the family can drive the elderly driver more safely. Since an elderly driver has a limited driving range, position information is limited from the driving range.

  Informing the warning based on the climate information detected by the temperature / humidity sensor 16 or the like and the position information acquired by the GPS unit 12 or the like, for example, the temperature is such that a danger such as heat stroke is predicted. When the height is high, a warning that prompts hydration may be notified by the display means or the speaker 22 after moving a predetermined distance from the position information of the start position. Thereby, it is possible to reduce the possibility of an accident in which an elderly driver accidentally becomes a perpetrator due to heat stroke.

  The warning notification by the display device 18 or the speaker 22 is not something that strongly restricts the action. For example, as shown in the advice, “It is better to drink water because the temperature is high.” It ’s better to open a window, or something that calls attention, and encourages action. In addition, the warning to be notified is a notice of words such as “If you drive for a long time, your concentration will decrease” or when it rains, “Since it rained, it ’s slippery” It ’s a good idea to let them know.

  Further, for example, as shown in FIG. 3, the notification unit may include a display screen that can display a single color background, and the display screen may notify a warning by changing the color of the background.

  In this way, a change in color, which is visual information that is most easily recognized by an elderly driver, is reported as a single color change particularly in the background of the entire display screen where the change is easy to recognize. As a result, the warning can be surely recognized by the elderly driver, so that the probability of an accident caused by the driving of the elderly driver is reduced, and the family can drive the elderly driver with peace of mind.

  The “color change” may be changed from the state in which the display screen normally displays real-time image information captured by the front view camera 11 to red. Thereby, compared with the change to colors other than red, it is easy for the elderly driver to understand that the state is different from the normal state, and the probability that an accident caused by the driving of the elderly driver can be reduced. The “color change” may be a change in which the background of the same color blinks or a change in which the backgrounds of different colors are sequentially replaced.

  For example, even for an elderly driver who is driving with various visual acuity diseases such as cataracts, the change in the color of the display background is most easily recognized intuitively compared to the warning by text. By memorizing that the danger is notified by the color, the possibility of becoming a perpetrator of the accident is reduced.

  Further, for example, the notification means includes warning sound output means such as a speaker 22 that notifies the warning by sound, and the display screen of the display device 18 can display the warning by characters in addition to the display background. In accordance with the above-described characteristics, a warning may be notified by the notification means by a combination of the color of the front display background and at least one of the character and the sound.

  In this way, it is easy for an elderly driver to recognize the warning by notifying the warning by a combination of at least one of characters and sounds in addition to the color of the display background. In particular, an elderly driver may have a physical problem. In such a case, even if it is difficult to recognize the warning by one method, the elderly driver can recognize the warning.

  For example, the display screen of the display device 18 may be configured to have no elements other than the background and characters. For example, the display screen 18 may have a function of notifying an alert only with characters and background colors without displaying icons and maps. Further, for example, the red color may be set to a color that is easy for an elderly driver to recognize.

  Further, for example, at least one of the color of the display background displayed on the display screen of the display device 18, the characters, and the sound emitted from the speaker 22 is set by the family of the elderly driver in accordance with the characteristics of the elderly driver. It is good to have a function.

  In this way, the family who knows the elderly driver best can set the warning information in accordance with the characteristics of the elderly driver, and can notify the warning that is most easily recognized. As a result, the elderly driver can drive the vehicle under the love of the family, and the awareness of trying to prevent an accident is increased.

  As the setting method, for example, a plurality of combinations of display background color and character color are prepared in the initial setting, and only the content of the warning text by characters is changed by the touch panel 19 of the display device 18. Good. By doing so, it is possible to individually set the contents to be alerted with easy-to-see color combinations according to the characteristics of the elderly driver.

  In addition, it is also conceivable that the device according to the present invention is a reason for going out because driving a car prevents an elderly driver from being withdrawn at home and leads to health promotion. For example, such an in-vehicle device in which such an elderly driver does not become a perpetrator of an accident counts the frequency of driving the vehicle based on whether or not the engine is started from the OBD connector 13, and the elderly driver It is preferable to display on the display device 18 reward information that can give motivation for driving. For example, when the number of days that the vehicle has been driven is counted, and the predetermined number of days is counted, reward information that can motivate the elderly driver to drive may be displayed on the display means.

  Reward information is displayed according to the number of days that the elderly driver starts the engine and drives the vehicle, which gives the elderly driver the motivation to drive and motivates them to drive even every day. . Thereby, an elderly driver does not dislike driving and is not withdrawn, and an environment in which an elderly driver can safely drive an elderly driver can be provided.

  The “reward information” may be, for example, a photographic image of the family of an elderly driver as shown in FIG. Older drivers have a deep affection for their families, so doing so can increase the motivation to drive with reward information.

  Further, for example, the control means 10 may display the reward information without performing the deduction process for the frequency of driving the vehicle. By doing so, the deduction points do not prevent the elderly driver from driving, and the motivation to drive based on reward information is not hindered. For example, even when a sudden start, sudden braking, etc. are acquired from the acceleration sensor 14 during driving, or when the driving distance does not reach the predetermined distance where normal driving is planned, Count the days you drive without causing an accident. For example, the count may only be added. If the day count may be subtracted, it may reduce the motivation for the older driver to continue driving every day, but since the day count is only added, the older driver simply You only have to think about driving and you can keep driving every day. As a result, it is possible to provide an environment where the elderly driver's family can safely drive the elderly driver.
