[Explanation of operation]
Next, the probe information transmission process executed by the information display device 200 will be described. FIG. 7 is a flow chart showing an example of probe information transmission processing. The probe information transmission process is started, for example, when the information display device 200 is started.

The probe information transmission process is a process performed independently of the search route acquisition request process and the passing difficult section avoidance notification process, which will be described later, and is periodically (for example, every 5 minutes) after the information display device 200 is started. Executed every 10 minutes, etc.).

When such processing is started, the transmission information generation unit 223 transmits the vehicle specification information to the server device 100 (step S001). Specifically, the transmission information generation unit 223 generates screen information for receiving input of vehicle specifications including at least the vehicle width from the user via the output processing unit 222, and outputs this to the output device 402 (or display). It is displayed in 502). Further, the transmission information generation unit 223 acquires the vehicle specifications including the vehicle width from the user via the input reception unit 221.

When the vehicle specifications including the vehicle width are stored (registered) in advance in the storage unit 210 of the information display device 200, the transmission information generation unit 223 may acquire the vehicle specifications from the storage unit 210.

Next, the transmission information generation unit 223 acquires the position information of the vehicle from the GPS receiving device 407 (or the GPS receiving device 509) (step S002). Further, the transmission information generation unit 223 acquires the vehicle direction from the gyro sensor 406 (or the gyro sensor 508) (step S003). Further, the transmission information generation unit 223 generates probe information 112 in which the vehicle position information, the vehicle orientation, and the vehicle specifications are associated with the vehicle identification information (for example, a predetermined identification number generated by the transmission information generation unit 223). (Step S004).

Next, the transmission information generation unit 223 transmits the probe information 112 to the server device 100 via the communication unit 230 (step S005), and returns the process to step S001.

The probe information transmission process has been described above.

Next, the search route acquisition request processing executed by the information display device 200 will be described. Such processing is started when the input receiving unit 221 accepts the input of the departure place and the destination. The search route acquisition request process is a process performed independently of the probe information transmission process and the passing difficult section avoidance notification process described later, and is executed every time a new departure point and destination input is received.

When the process is started, the transmission information generation unit 223 generates search route acquisition request information including the departure place and destination that received the input and the vehicle identification information, and the server device 100 via the communication unit 230. Send to.

When the route search unit 121 of the server device 100 acquires the search route acquisition request information from the information display device 200 via the communication unit 130, the route search unit 121 searches for a recommended route connecting the departure point and the destination included in the information. Further, the route search unit 121 transmits the searched recommended route to the information display device 200 via the communication unit 130. Further, the route search unit 121 stores the searched recommended route in the storage unit 110 in association with the identification information that identifies the source vehicle of the search route acquisition request information.

Further, when the output processing unit 222 of the information display device 200 acquires the recommended route from the server device 100 via the communication unit 230, the output processing unit 222 displays this on the output device 402 (or the display 502). Further, a functional unit (not shown) of the information display device 200 provides route guidance using the acquired recommended route.

When the information display device 200 is an on-board unit, has a route search unit 121, and has map information in the storage unit 210, the search route acquisition request process is not an essential process. For example, the route search unit of the information display device 200 may search the route using the map information. When the route search unit of the information display device 200 searches for a recommended route, the searched recommended route is transmitted to the server device 100 via the communication unit 230.

The search route acquisition request processing has been described above.

Next, the passing difficult section avoidance notification process executed by the server device 100 will be described. FIG. 8 is a flow chart showing an example of a difficult-to-pass section avoidance notification process. Such processing is started, for example, when the server device 100 is started. The difficult-to-pass section avoidance notification process is a process performed independently of the probe information transmission process and the search route acquisition request process described above, and is periodically (for example, every 5 minutes, 10) after the server device 100 is started. Executed every minute, etc.).

When the process is started, the difficult-to-pass section identification unit 122 determines whether or not the probe information 112 has been acquired from the information display device 200 via the communication unit 130 (step S011). Then, when it is determined that the probe information 112 has not been acquired (No in step S011), the passing difficult section specifying unit 122 performs the process of step S011 again. On the other hand, when it is determined that the probe information 112 has been acquired (Yes in step S011), the passing difficult section identification unit 122 shifts the process to step S012.

Next, the difficult-to-pass section specifying unit 122 identifies the source vehicle of the probe information 112 (step S012). Specifically, the difficult-to-pass section identification unit 122 identifies the source vehicle of the probe information 112 by using the vehicle identification information included in the probe information 112.

Next, the difficult-to-pass section specifying unit 122 determines whether or not the route has been searched for the specified vehicle (step S013). Specifically, the difficult-to-pass section specifying unit 122 determines whether or not the route has been searched based on whether or not the recommended route to which the identified vehicle identification information is associated is stored in the storage unit 110. .. Then, when it is determined that the route search has not been completed (No in step S013), the passing difficult section specifying unit 122 returns the process to step S011.

On the other hand, when it is determined that the route has been searched (Yes in step S013), the passing difficult section specifying unit 122 shifts the process to step S014. Even when the search route is stored in the storage unit 110, the difficult-to-pass section identification unit 122 refers to the position information and the vehicle direction included in the probe information 112 acquired from the vehicle, and refers to the recommended route specified by the vehicle. If the vehicle is not traveling above, the process returns to step S011.

Next, the passing difficult section specifying unit 122 determines whether or not there is a passing difficult section (step S014). Specifically, the difficult-to-pass section specifying unit 122 refers to the course direction 151 of the link included in the recommended route by using the specified recommended route and map information. Then, when a link whose course direction 151 is "two-way traffic is possible" is included, the passing difficult section specifying unit 122 determines that there is a passing difficult section. This is because the road indicated by such a link indicates a one-lane road in which the up and down roads are not separated, and it is highly possible that vehicles pass each other in a narrow road width on such a road.

Then, when it is determined that there is no difficult-to-pass section (No in step S014), the difficult-to-pass section specifying unit 122 returns the process to step S011. On the other hand, when it is determined that there is a difficult-to-pass section, the difficult-to-pass section specifying unit 122 shifts the process to step S015.

When there are a plurality of difficult-to-pass sections, the difficult-to-pass section specifying unit 122 specifies all the difficult-to-pass sections.

Next, the passing vehicle detection unit 123 determines whether or not there is a passing vehicle that may pass each other in the difficult-to-pass section (step S015). Specifically, the passing vehicle detection unit 123 uses the probe information 112 to identify the current location of the vehicle in which the information display device 200 is located. In addition, the passing vehicle detection unit 123 calculates the estimated arrival time when the vehicle arrives at the difficult-to-pass section by using the traffic information such as the recommended route, the map information 111, and the VICS information.

More specifically, the passing vehicle detection unit 123 integrates the travel time 149 of the link included in the search route, and determines the number of traffic lights existing between the current location and the difficult-to-pass section and the congestion situation. The estimated arrival time (for example, 19:05) to the difficult-to-pass section is calculated by multiplying the coefficients of.

In addition, the passing vehicle detection unit 123 uses the link length 146 and the travel time 149 of the map information 111 to calculate the expected escape time (for example, 19:06) at which the vehicle finishes traveling in the difficult-to-pass section. Further, the passing vehicle detection unit 123 has a passing estimated time (for example, 19:04 to 19:04) including a predetermined error time (for example, an error time of about 60 seconds to 300 seconds) before the expected arrival time and after the expected escape time, respectively. 19:06) is calculated.

In addition, the passing vehicle detection unit 123 determines whether or not there is an oncoming vehicle (another vehicle) that may pass through the difficult-to-pass section at the expected passing time. Specifically, the passing vehicle detection unit 123 passes the difficult-to-pass section by using the probe information 112 acquired from another vehicle, the recommended route of the other vehicle, the map information 111, the VICS information, and the like, as described above. Determine if there is an oncoming vehicle that may pass at the expected time.

Then, when it is determined that there are other vehicles that may pass each other, the passing vehicle detection unit 123 identifies the widths of both vehicles that may pass each other by using the vehicle specifications acquired from the information display device 200. do. Further, the passing vehicle detection unit 123 uses the map information 111 to specify the link width (road width) 147 of the difficult-to-pass section. Then, when the value obtained by subtracting the sum of the vehicle widths of both vehicles from the link width 147 is smaller than a predetermined value (for example, about 2 m), the passing vehicle detection unit 123 states that there is a passing vehicle in a difficult-to-pass section. judge. On the other hand, when such a value is larger than a predetermined value, the passing vehicle detection unit 123 determines that there is no passing vehicle in the difficult-to-pass section. This kind of processing is for considering that if there is sufficient space in the road width when passing each other, even if there is a passing vehicle, it will not be a problem of running.

When it is determined that there is no passing vehicle (No in step S015), the passing vehicle detection unit 123 returns the process to step S011. On the other hand, when it is determined that there is a passing vehicle (Yes in step S015), the passing vehicle detection unit 123 shifts the process to step S016.

When there are a plurality of other vehicles that may pass each other, the passing vehicle detection unit 123 determines whether or not there is a passing vehicle in the difficult-to-pass section for all the passing vehicles. Further, when there are a plurality of difficult-to-pass sections, the passing vehicle detection unit 123 determines whether or not there is a passing vehicle in all the difficult-to-pass sections.

Next, the route search unit 121 searches for an avoidance route that avoids (detours) the difficult-to-pass section (step S016). For example, the route search unit 121 sets the cost of the difficult-to-pass section determined that there is a passing vehicle higher than that of other links, and searches for an avoidance route connecting the vehicle position to the destination included in the latest probe information 112. do.

Further, the route search unit 121 calculates the estimated arrival time at the destination when traveling on the searched avoidance route, and shifts the process to step S017. Since the method of calculating the estimated arrival time is the same as the method of calculating the estimated arrival time in the above-mentioned difficult-to-pass section, the description thereof will be omitted.

Next, the display information generation unit 124 generates display information including the avoidance route (step S017). Specifically, the display information generation unit 124 uses the recommended route (current route) before searching for the avoidance route, the avoidance route, the difficult-to-pass section, the passing vehicle in the difficult-to-pass section, and the passing vehicle in the difficult-to-pass section. Generates display information including a predetermined message notifying that there is, a map display area including, and an estimated time of arrival at the destination when traveling on the current route and when traveling on the avoidance route.

FIG. 9 is a diagram showing an example of display information. As shown in the figure, the display information includes the recommended route (current route) 601 before searching for the avoidance route, the avoidance route 602, the difficult-to-pass section 603, and the passing vehicle 604 in the difficult-to-pass section 603 in the map display area. Is displayed in. Also, in the map display area, a predetermined message notifying that there is a passing vehicle 604 in the difficult-to-pass section 603 (for example, "Passing occurs on a narrow road on the route. Do you want to avoid it?" ) 605 and an instruction input button 606 for receiving an instruction to avoid passing each other from the user are displayed. In addition, the displayed information displays the estimated arrival time 607 to the destination when the vehicle travels on the current route and when the vehicle travels on the avoidance route.

The information display device 200 acquires display information from the server device 100 via the communication unit 230. Further, the output processing unit 222 of the information display device 200 displays the acquired display information on the output device 402 (or the display 502). As a result, the user can know in advance where there is a difficult-to-pass section on the recommended route, that the section passes by another vehicle, and the number of vehicles that pass each other. In addition, since the displayed information includes the current route and the avoidance route, and the estimated arrival time to the destination when traveling on the avoidance route, whether or not the user selects the avoidance route in comparison with the current route. Can be determined.

Further, for example, when the user selects the instruction input button 606 (“Yes” button in the figure) for instructing to avoid passing each other, the input reception unit 221 uses the communication unit 230 to search for the avoidance route. Is transmitted to the server device 100. Further, when such information is acquired from the information display device 200, the route search unit 121 of the server device 100 generates guidance information for guiding the route of the avoidance route and transmits it to the information display device 200 via the communication unit 130. .. When the information display device 200 acquires the guidance information, the information display device 200 uses the information display device 200 to provide route guidance for the avoidance route.

The passing difficult section avoidance system according to this embodiment has been described above. According to such a difficult-to-pass section avoidance system, it is possible to avoid a road section where it is difficult to pass each other. As a result, the user can determine in advance whether to travel in a section where it is difficult to pass each other or to travel on a route that avoids passing each other.
