  The navigation device 12 mounted on the vehicle 2 transmits the current position information to the warning notification system 1 by wireless communication and receives a danger information notification from the warning notification system 1. When the danger information notification is received, a predetermined warning is given to the driver. For example, the driver of the vehicle 2 is warned by displaying a warning message on the screen of the navigation device 12 or reproducing the warning message by voice.

  The warning notification system 1 of the present invention is capable of transmitting and receiving information to and from a navigation device 12 mounted on a vehicle 2 via a network 3 such as wireless communication, and includes an information receiving unit 4 and a driver information storage unit. 5, dangerous place information storage means 6, dangerous place determination means 7, dangerous value calculation means 8, danger degree determination means 9, dangerous information notification means 10, and dangerous place information update means 11.

Information received includes current position information of the vehicle 2 on which the navigation device 12 is mounted, driver identification information for identifying the driver, traveling course identification information for identifying the traveling course on which the driver is traveling, and the like.

  The driver information storage means 5 is means for storing information related to the driver. Driver information includes driver identification information, driver name, driver's physical information (sight, hearing, obesity, etc.), driving history, carelessness factors such as violation history and accident history, Experience (number of trips and running time), working hours of the day, risk sensitivity test results, etc. FIG. 3 shows a conceptual diagram of the driver information storage means 5.

  The dangerous place information storage means 6 is means for storing information related to the dangerous place. Information on the dangerous place includes the location information of the dangerous place, image information of the place, information on the contents of the danger occurring at the place (jumping out, poor visibility, etc.), and information indicating in which case the danger is present (for example, Limited to rainy weather and large vehicles). In addition, in order to calculate a dangerous value of a dangerous place described later, if there is a dangerous factor corresponding to the place, the dangerous value of the dangerous factor is stored. For example, as factors of a dangerous place, “forecast is bad” (dangerous value = x1), “much popping out” (dangerous value = x2), “many passersby” (dangerous value = x3), “other” (dangerous value) = 4) If there are four factors of x4), in the dangerous place corresponding to all of these, the sum of the dangerous values of x1, x2, x3, x4 becomes the dangerous value of the dangerous place, and " In a dangerous place corresponding to “many passersby”, the sum of x2 and x3 is the dangerous value of the place. Therefore, the dangerous place information storage means 6 stores the dangerous value of each risk factor of the dangerous place. FIG. 4 shows a conceptual diagram of the dangerous place information storage means 6.

  Based on the current position information of the vehicle 2 received from the information receiving means 4, the dangerous place determination means 7 determines whether the current position place is within a predetermined range (for example, within a radius of 100 m) from the dangerous place. Is compared with the position information of the dangerous place stored in the dangerous place information storage means 6. The predetermined range from the dangerous place may be limited to the predetermined range in the traveling direction of the vehicle 2. This is because by limiting to the traveling direction, it is possible to reduce the number of comparison objects, leading to an improvement in processing speed.

  The dangerous value calculating means 8 is a means for calculating the dangerous value of the driver based on a predetermined method when the dangerous place is located in the dangerous place based on the determination result of the dangerous place determining means 7. At this time, the calculation is made taking into account the experience value of the driving course of the driver.

  The danger level determination means 9 calculates the dangerous value of the dangerous place based on the dangerous value of each factor of the dangerous place stored in the dangerous place information storage means 6, and the driver's risk calculated by the dangerous value calculation means 8. The value is compared with the dangerous value at the location, and it is judged dangerous if the predetermined risk judgment condition (the dangerous value of the driver is greater than or greater than the dangerous value of the location) Means.

  When the risk information notifying unit 10 determines that the risk is dangerous, the risk information notifying unit 10 stores image information of the location, information on the details of the danger, and information indicating in which case the risk is dangerous. And transmitting information on various dangerous places acquired by the risk determination means 9 to the navigation device 12 via the network 3.

  The dangerous place information update means 11 is a means for newly registering a place where the driver feels dangerous as a dangerous place. From the computer terminal (including the portable terminal) and the navigation device 12 used by the driver, Information on the location of the dangerous place, information on the contents of the danger occurring in the place, information indicating in which case it is dangerous, and if there is an image, the image information is received and stored in the dangerous place information storage means 6 It is a means to make.

  Next, an example of the processing process of the warning notification system 1 of the present invention will be described with reference to the flowchart of FIG. 2 and the system configuration diagram of FIG. In the following description, a case where a driver of a business operator who performs truck transportation travels on a predetermined traveling course by the vehicle 2 provided with the navigation device 12 will be described.

  The driver inputs driver identification information and information for identifying the traveling course from the navigation device 12 before starting the boarding (S100). The input information is transmitted from the navigation device 12 to the warning notification system 1. The information receiving means 4 of the warning notification system 1 receives these pieces of information. By receiving such information, it is grasped that the driver's boarding (working) has started, and the working time of the day is recorded in the driver information storage means 5 as needed. Also, by inputting these information, it is possible to grasp which driver is running which course.

  The driver starts driving the vehicle 2 (S100). Accordingly, the current position information of the vehicle 2 is sequentially transmitted from the navigation device 12 to the warning notification system 1. The driver identification information and the information for identifying the traveling course may be transmitted once at the beginning, but may be sequentially transmitted together with the current position information.

  When the current position information of the vehicle 2 transmitted by the navigation device 12 is received by the information receiving means 4 of the warning notification system 1 (S130), the dangerous place determination means 7 receives the current position information and dangerous place information storage means 6 of the vehicle 2. Is compared with the location information of the dangerous place memorized in (1), and it is determined whether it is within the predetermined area (for example, within a radius of 100 m) from the dangerous place.

  If the result of this determination is that it is not in a dangerous place or within a predetermined range, the warning notification system 1 need not do anything. In the case of the dangerous place or within the predetermined range, the dangerous value calculation means 8 calculates the dangerous value of the driver in consideration of the driver's experience value based on the predetermined method (S140).

  Specifically, for example, the risk value is calculated in consideration of the following seven elements. A conceptual diagram of risk value calculation is shown in FIG.

The first element A calculates a value A obtained by multiplying the working time by a predetermined coefficient a in view that the intention determination is lowered as the working time becomes longer. That is,
(Equation 1)
A = working hours x coefficient a
Is calculated. Note that the value A may be calculated by multiplying the working time by a coefficient a only for a time exceeding a predetermined time, instead of all the working time.

  Since the working time is calculated by storing the working time of the day in the driver information storage unit 5, the danger value calculating unit 8 acquires the working time from the driver information storage unit 5. If it is a positive value, it can be calculated by multiplying by a coefficient a.

The second factor B is that a driver who has no carelessness may cause an accident or violation if the driver's past carelessness (accident history, violation history) exceeds a predetermined number of times. Therefore, a value B obtained by multiplying the number of careless elements by a coefficient b is calculated. That is,
(Equation 2)
B = number of careless elements × coefficient b
Is calculated.

  Since the number of careless elements is stored in the driver information storage means 5 in the driver's past careless elements, the risk value calculation means 8 determines the number of careless elements from the driver information storage means 5. By obtaining, it can be calculated by multiplying the number of careless elements by the coefficient b.

In view of the fact that the third element C has a high possibility of causing an accident or a violation because a low level of proficiency with the driving course has a low awareness of the danger, If the value is equal to or less than the predetermined value, the value C is added to the determination element for calculating the dangerous value. The value C may be a plurality of values according to the experience of the traveling course. For example the running count Once 10 times the value _C 1, 11 times to 20 times the value _C 2, 21 times to 50 times the value _C 3, 51 times to 100 times can be as the value _{C 4} .

  The experience value of the travel course is stored in the driver information storage means 5 because the driver's experience value of the travel course currently being traveled is stored, so the risk value calculation means 8 acquires the experience value, When the experience value is equal to or less than the predetermined value, the value C is added to the determination element for calculating the dangerous value.

The third element C is not only added to the determination element when the experience value is equal to or less than the predetermined value as described above,
(Equation 3)
C = experience value × coefficient c
It is also possible to calculate the value C and add it to the decision element.

  The fourth factor D is that if the driver has left the driving course for some reason, such as traffic jams or accidents in the driving course, the driver may have an accident or violation due to an unfamiliar driving course. In view of the fact that the vehicle travels outside the predetermined travel course, the predetermined value D is added to the determination element for calculating the danger value.

  The current position information of the driver's vehicle 2 is sequentially received by the information receiving means 4 from the navigation device 12 of the vehicle 2, and a risk value is calculated as to whether or not the current position information is on the traveling course of the vehicle 2. By determining by means 8, it can be determined whether or not the vehicle has deviated from the traveling course. If it is not, the dangerous value calculation means 8 adds the predetermined value D to the determination element for calculating the dangerous value.

  In the fifth element E, if the experience value exceeds the predetermined value in the third element C, the value C may be excluded from the determination element for calculating the dangerous value. Warning is less likely to occur. However, if the experience value exceeds the predetermined value, the driver may skip driving due to the habituation unless the value C is considered as an element all the time thereafter. Therefore, the fifth course E is added to the risk factor determination element for each predetermined experience value in the travel course.

  Similarly to the third element C, the experience value of the travel course is stored in the driver information storage means 5 because the experience value of the travel course that the driver is currently traveling is stored. 8 acquires the experience value, and when the experience value is a multiple of a predetermined experience value (for example, when the number of times of travel is a multiple of 10), the dangerous value calculation means 8 uses the value E as a determination element for calculating the dangerous value. Will be added.

The sixth element F is a risk that varies depending on the individual driver when a risk occurrence test (risk sensitivity test) is performed on the driver in advance and the risk sensitivity of the driver is quantified. Judgment can be made in consideration of sensitivity. For example, a driver who feels unsafe (ie, has a poor risk sensitivity test score) may need to give more warnings than other drivers, and is sharper to feel dangerous (ie In the case of a driver (having a good risk sensitivity test score), it is considered that the warning may be less than that of other drivers. Therefore, when the risk sensitivity test result is digitized in advance and stored in the driver information storage means 5, the risk value calculation means 8 obtains the numerical value and multiplies it by a predetermined coefficient f. Is calculated. That is,
(Equation 4)
F = numerized hazard sensitivity × coefficient f
Will be calculated.

  The seventh element G is a driver's physical attribute (for example, a bird's eye, a tendency of hearing loss, considering that the risk may increase if there is any cause in the driver's physical attribute, If any factor such as the degree of obesity is equal to or greater than a predetermined value is satisfied, the value G is added to the determination element for the risk value calculation.

  In this case, since the driver's physical information is stored in the driver information storage means 5, the risk value calculation means 8 adds the value G to the determination element for the risk value calculation if this is the case.

By summing the value G from the value A thus calculated and subtracting it from 100, the danger value calculation means 8 calculates the danger value of the driver. That is,
(Equation 5)
Driver risk value = 100− (A + B + C + D + E + F + G)
Is calculated by the dangerous value calculating means 8.

On the other hand, the risk level determination means 9 first calculates the risk value of the dangerous place based on the risk value of each factor of the dangerous place stored in the dangerous place information storage means 6 (S150). The danger value of this dangerous place can be obtained by acquiring each risk factor of the corresponding dangerous place and calculating the sum total thereof because the current position information of the vehicle 2 is received by the information receiving means 4. That is,
(Equation 6)
The danger level determination means 9 calculates the sum of the danger values of each danger factor in the dangerous place.

  The risk determination means 9 compares the driver's risk value calculated by the risk value calculation means 8 with the risk value of the dangerous place (S160), and determines a predetermined risk determination condition (the driver's risk value is the location). It is determined that it is dangerous.

  If it is determined in S160 that it is dangerous, the danger information notifying unit 10 acquires image information of the location, information on the contents of the danger, and information indicating in which case it is dangerous from the dangerous place information storage unit 6. Then, information regarding these various dangerous places is transmitted to the navigation device 12 via the network 3 (S170).

  Based on the information on the dangerous place received from the warning notification system 1, the navigation device 12 warns the driver by displaying information on the dangerous place on the screen or on the screen (S180).

  The above processing process is repeated until the driver finishes traveling. Then, after driving, if there is a new place where the driver feels dangerous, the location information of the dangerous place and the contents of the danger occurring at that place are obtained from the computer terminal or navigation device 12 used by the driver. Information, information indicating in which case it is dangerous, and image information, if any, are input and transmitted to the warning notification system 1. When the dangerous place information update unit 11 receives these and determines that the dangerous place is not yet registered in the dangerous place information storage unit 6, the dangerous place information update unit 11 determines whether it is registered based on the position information. These are newly stored as dangerous places in the dangerous place information storage means 6 (S190).

  The risk value calculation by the risk value calculation means 8 described above is not limited to the case where all of the above seven elements are used, and one or more elements are considered without considering all the seven elements. You can do it. For example, when only the proficiency level of the traveling course is considered as a problem, only the element C and the element D may be added as dangerous values. In addition, when taking into account the abbreviated operation that comes from experience, the element E may be added as a dangerous value. In this way, the danger value may be calculated by appropriately combining the seven elements. In addition to calculating the dangerous value from each element by addition, it is possible to calculate the dangerous value of the driver taking into account the experience value by various methods using various operators.

  When not only calculating the dangerous value but also determining whether each element is determined by the dangerous value calculating means 8, if the condition for adding each element is satisfied, for example, if it falls under the element E, the dangerous information notifying means It is also possible to set so that danger information is automatically transmitted from 10 to the navigation device 12. In this case, it is not necessary to compare with the dangerous value of the dangerous place.

  Further, the risk level determination means 9 adds the respective factors of the dangerous place stored in the dangerous place information storage means 6 to calculate the dangerous value of the place, and previously stores the dangerous place risk information in the dangerous place information storage means 6. It is good also as comparing with a driver | operator's danger value by memorize | storing a value and acquiring it.

  Further, in the above-described embodiment, the risk judgment condition in the risk judgment means 9 is compared with the risk value of the dangerous place and the risk value of the driver. It is good also as comparing with a value. The risk determination condition in this case satisfies the condition if the driver's risk value is greater than or equal to a predetermined value or greater than the predetermined value, and is determined to be dangerous.

  In addition, as a further simple method in the risk determination condition, the risk value may be used instead of the driver's experience value. In this case, the risk determination condition is determined as dangerous when the driver's experience value is equal to or less than a predetermined value or smaller than a predetermined value. If this condition is satisfied, the danger information notifying means 10 acquires image information of the place, content information of the danger, and information indicating in which case it is dangerous from the dangerous place information storage means 6, and the navigation is performed. Transmit to device 12. In addition, the driver's experience value does not satisfy the above-described risk determination condition (the driver's experience value is equal to or less than a predetermined value or less than a predetermined value). The risk information notifying unit 10 acquires image information of the location, risk content information, and information indicating in which case the danger is present from the dangerous location information storage unit 6. Similarly, it is transmitted to the navigation device 12. Thus, even if there is a certain experience value or more, the driver's omitted driving can be prevented by transmitting the danger information for each predetermined value. In this way, when the risk determination condition is mainly based on the experience value of the driver by a simple method that does not use the risk value, a process such as calculation of the risk level may not be provided.

Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area. The storage means can store information in various data storage formats such as a database and a data file.

  According to each of the above-described inventions, when approaching a dangerous place, a warning is given to a driver with little experience as usual, and a warning with a certain level of experience is not always given, but at an arbitrary timing. A warning can be made. Even if there is a certain level of experience, there is a case where the user may be off the driving course. In such a case, a warning can be given.

By using such a warning notification system 1, a warning is not always issued to the driver, so that the driver can be frustrated. In addition, by not giving warning at all but by giving warning at an arbitrary timing, the driver can be re-recognized that the place is a dangerous place. This can also prevent the driver from forgetting that the place is a dangerous place.
