Overall view of the driving support system according to the embodiment of the present invention Block diagram of the notification device according to the embodiment of the present invention Explanatory drawing about predicted passing range by embodiment of this invention Flow chart regarding the operation of the calculation unit according to the embodiment of the present invention

Hereinafter, the driving support system 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, the driving support system 1 includes a notification device 2 mounted on the vehicle X and a server 3 installed on the communication center Y, and is configured to be able to communicate with each other wirelessly. .. The vehicle X is equipped with a position information detection device Z. In the present embodiment, it is assumed that a GPS device is mounted as the position information detection device Z. As the position information detection device Z, a smartphone can be adopted, and further, the smartphone can also serve as the notification device 2.

As shown in FIG. 2, the notification device 2 includes an acquisition unit 21, a vehicle-side transmission unit 22, a vehicle-side reception unit 23, and a notification unit 24.

The acquisition unit 21 acquires the position information of the vehicle X in association with the time information. In the present embodiment, the position information is acquired from the position information detection device Z.

The vehicle-side transmission unit 22 transmits a request signal for requesting restriction information based on the Road Traffic Act in association with the position information and the driver ID of the vehicle X. In the present embodiment, the restriction information is "a road sign based on an order concerning road signs, lane markings and road signs based on the provisions of Article 45, Paragraph 2 of the Road Law and Article 9, Paragraph 3 of the Road Traffic Law. And road signs and regulatory information ”, and speed limits and temporary stops can be considered. The above restriction information is an example in the case of Japan, and in the case of other countries, it is conceivable to use similar laws and regulations as restriction information. The request signal is preferably transmitted periodically over a short span.

The vehicle side receiving unit 23 receives the response signal.

The notification unit 24 notifies the driver of the vehicle X based on the received response signal. As the notification unit 24, it is conceivable that the road on which the vehicle is traveling is displayed on the display screen, and the notification is displayed at the corresponding location on the displayed road based on the restriction information included in the response signal. At the same time, voice notification may be performed.

As shown in FIG. 1, the server 3 includes a storage unit 31, a server-side receiving unit 32, a calculation unit 33, and a server-side transmitting unit 34.

The storage unit 31 determines whether or not to notify the restriction information based on the Road Traffic Act linked to the position information, the plurality of types of road traffic law compliance information of the driver of the vehicle X linked to the ID, and whether or not to perform the notification. It remembers the notification standard for judgment. Road traffic law compliance information is stored for each type of restriction information, such as "speed limit violation: 10 times" and "pause violation: 1 time". Further, it is preferable that the notification standard is also set for each type of restriction information, such as "speed limit violation: 5 times or more" and "pause violation: 2 times or more". In addition, the storage unit 31 also stores position information and map information based on the coordinates.

The server-side receiving unit 32 receives the request signal transmitted from the vehicle-side transmitting unit 22.

The calculation unit 33 calculates the predicted passage range A (see FIG. 3) that the vehicle X will pass after a predetermined time based on the position information included in the request signal, and among the restriction information stored in the storage unit 31. The restriction information in the predicted passage range A is extracted from. In the present embodiment, the speed of the vehicle X is calculated based on the position information transmitted periodically, and then the predicted passing range A is calculated based on the calculated speed.

At this time, the calculation unit 33 does not extract the corresponding restriction information for the plurality of types of road traffic law compliance information that do not meet the notification standard. For example, if the number of "pause violations" is small in the road traffic law compliance information of the driver of vehicle X, even if there is "pause" restriction information in the predicted passage range A, "temporary stop" The restriction information of "stop" will not be extracted.

Further, the calculation unit 33 calculates the predicted passage range A in consideration of the time required for at least one of the above calculation and extraction.

The server-side transmission unit 34 transmits the extracted restriction information as a response signal in the predicted passage range A.

Subsequently, the operation of the calculation unit 33 will be described with reference to the flowchart of FIG.

First, when the server-side receiving unit 32 receives the request signal (S1: YES), the predicted passing range A that the vehicle X will pass after a predetermined time is calculated based on the position information included in the request signal (S2). , The restriction information in the predicted passage range A is extracted from the restriction information stored in the storage unit 31 (S3).

Finally, the server-side transmission unit 34 is made to transmit the extracted restriction information as a response signal in the predicted passage range A (S4).

At this time, the response signal does not include restriction information corresponding to a plurality of types of road traffic law compliance information that do not meet the notification standard. Therefore, only the restriction information for the Road Traffic Act item, which is frequently violated by the driver of the vehicle X, is transmitted.

Here, at the time when the request signal is received in S1, the vehicle X is calculated to pass through the range B after a predetermined time as shown in FIG. 3, but the above calculation and extraction take time. By the time the notification device 2 receives the response signal (restriction information), the range B is approaching, and it is conceivable that the notification by the notification unit 24 may not be in time or may reach the limit.

Therefore, in the present embodiment, in S2, the predicted passing range A is calculated in consideration of the time required for calculation and extraction, and then in S3 and S4, the restriction information in the predicted passing range A is extracted and transmitted. As a result, the driver can respond to the restricted information with a margin.

As described above, in the driving support system 1 according to the present embodiment, the predicted passing range A is calculated based on the position information of the vehicle X, and the restriction information in the predicted passing range A is transmitted as a response signal. Does not include restriction information corresponding to multiple types of road traffic law compliance information that do not meet the notification standards.

According to such a configuration, in the predicted passing range A, only the restriction information for the type of the Road Traffic Act with a high frequency of violation is notified to the driver of the vehicle X, so that the compliance with the Road Traffic Act is observed. It is possible to prompt appropriately.

Further, in the driving support system 1 according to the present embodiment, the predicted passing range A is calculated in consideration of at least the time required for either calculation or extraction.

According to such a configuration, it is possible to notify the vehicle X moving at high speed at an appropriate timing.

Further, in the driving support system 1 according to the present embodiment, the corresponding restriction information is not extracted for the information that does not meet the notification standard among the plurality of types of road traffic law compliance information.

The driving support system of the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope of the claims.

For example, in the above embodiment, the calculation unit 33 does not extract the corresponding restriction information for the plurality of types of road traffic law compliance information that do not meet the notification standard, but does extract the information. So, even if the configuration does not transmit the corresponding restriction information (does not include it in the response signal), it says, "For the driver of vehicle X, only the restriction information for the type of Road Traffic Act that frequently violates is notified." The purpose is achieved.

Further, in the above embodiment, the predicted passing range A is calculated by using the example in which the vehicle X goes straight, but it is also conceivable that the vehicle X makes a right turn or a left turn. Therefore, the predicted passing range A may be calculated in consideration of the case of making a right or left turn. In this case, it is conceivable to give a notification that is not confused with the case of going straight, such as "When turning right, the speed limit is XX".

Further, when making a right or left turn, the vehicle X usually slows down before the intersection or the branch, so the vehicle X usually slows down within the predetermined range before the intersection or the branch by referring to the map information or the like stored in the storage unit 31. When a decrease in the speed of the vehicle X by a predetermined speed or more or a decrease in the speed of the vehicle X below a predetermined speed is detected, the predicted passing range A may be expanded so as to include a case of making a right or left turn. In this case, since the speed of the vehicle X is decreasing, it is considered that the notification is not significantly delayed even if the predicted passage range A is expanded from the speed of the vehicle X to perform the notification.

Furthermore, in the above case, three types of notifications are given for going straight, turning right, and turning left, which may confuse the driver of vehicle X. Therefore, when a decrease in the speed of the vehicle X is detected within a predetermined range before the intersection or the branch, a plurality of predicted passage ranges A and the corresponding restriction information after the branch (in this case, 3 ways) are prepared. Then, when the route is confirmed (the position information of any of the routes is received), the response signal corresponding to the determined route may be transmitted to notify the route. As a result, since the preparation is made so that the notification can be performed immediately after the route is determined, it is possible to prevent the notification from being significantly delayed even if there is a branch.

Alternatively, the photographing device may be mounted at a position in the vehicle X where the driver can photograph, and the photographing device may be activated when the vehicle-side receiving unit 23 receives the response signal. For example, when the notification device 2 is a smartphone, it is conceivable to activate the camera of the smartphone and take a picture or a photograph.

According to such a configuration, a video or a photograph taken by the driver after the notification is given by the response signal is recorded, so that the driver of the vehicle X looks back on whether or not the road traffic law is complied with by the notification. It will be possible to promote compliance with the Road Traffic Act more appropriately. In addition, the administrator of the driving support system 1 can also change the timing and type of notification to an appropriate one based on the video or photograph.

Further, the present invention can be applied to a program corresponding to the processing performed by the calculation unit 33 and the like, and a recording medium in which the program is stored. In the case of a recording medium, the program will be installed on a computer or the like. Here, the recording medium in which the program is stored may be a non-transient recording medium. A CD-ROM or the like can be considered as a non-transient recording medium, but the non-transitory recording medium is not limited thereto.
