FIG. 3 is a sequence diagram showing processing executed by the information processing system 1. First, the position specifying unit 18 of the position positioning device 10 acquires the position information of the own device and the information indicating the behavior of the vehicle (step S100). Next, the collection unit 20 of the position positioning device 10 waits until a predetermined amount of position information and information indicating the behavior of the vehicle is accumulated in a storage device (not shown) of the own device (step S102). Next, the collection unit 20 of the position positioning device 10 transmits the information accumulated using the communication unit 22 to the performance record generation device 30 (step S104).

Next, the map matching unit 34 of the performance record generation device 30 executes map matching processing (step S106). Next, the travel record generation unit 36 of the track record generation device 30 generates travel record information for each road (step S108). Next, the performance generation device 30 transmits the generated travel performance information and information indicating the behavior of the vehicle to the specific area extraction device 80 (step S110). The travel record information may be transmitted to the position positioning device 10, and the display unit 28 of the position positioning device 10 may display an image indicating the travel record information. The image indicating the travel record information is, for example, an image in which the trajectory of the position positioning device 10 is displayed on the map.

Next, the extraction unit 82 of the specific area extraction device 80 extracts the specific area based on the travel record information (step S112). Next, the extraction unit 82 transmits the extracted information on the specific region to the position positioning device 10 (step S114). This completes the processing of one routine in this flowchart.

FIG. 4 is a flowchart showing the flow of processing executed by the extraction unit 82. A specific example of the process of this flowchart will be described with reference to FIG. First, the extraction unit 82 analyzes the behavior of the vehicle and derives an index (step S200). The index is a value that increases as the absolute value or the amount of change in the observation period such as velocity, acceleration, and angular velocity increases. Further, the index may be derived such that the larger the angle formed by the displacement vector when the displacement is extracted during the sampling period, the larger the value.

Next, the extraction unit 82 associates the derived index with the position of the vehicle at the time when the behavior of the vehicle used to derive the index was acquired. (Step S202). Next, the extraction unit 82 extracts a position where the index satisfies a predetermined reference as a specific area (step S204). This completes the processing of this flowchart.

FIG. 5 is a diagram for explaining a specific example of extracting a specific area. The illustrated example shows the trajectory of the vehicle acquired at a predetermined sampling interval when the predetermined vehicle travels in the lane L1. The extraction unit 82 analyzes the behavior (speed, acceleration, angular velocity) of the vehicle on each trajectory and derives an index.

Then, the extraction unit 82 compares the indexes and sets the position where the behavior of the vehicle satisfies a predetermined reference as the specific region. The predetermined criterion is an element (at least one of speed, acceleration, or angular velocity) included in the behavior of the vehicle at time t, and an element (at least one of speed, acceleration, or angular velocity) of the behavior of the vehicle at time t+1. Is more than a predetermined difference. That is, when the vehicle suddenly accelerates, decelerates, or makes a sharp turn, it is determined that the behavior of the vehicle satisfies a predetermined standard.

As described above, since the specific area is extracted based on the position information with higher accuracy, it is possible to provide the information on the specific area with higher accuracy. The highly accurate specific area information is information that has a small error from the position of the actual area corresponding to the specific area.

In addition, in the above-described example, the description has been made assuming that the index derived by analyzing the behavior of the vehicle is used, but in addition to (or instead of) the index derived from the change in the position of the vehicle may be used. .. The index derived from the change in the position of the vehicle is, for example, an index derived from at least one of the acceleration in the traveling direction, the acceleration in the lateral direction, and the degree of change in the turning angle derived from the loci of a plurality of vehicles. Is. In this case, it is determined whether or not each of the two indexes derived based on the behavior of the vehicle and the change in the position of the vehicle or the result of statistically processing the two indexes satisfies a predetermined criterion. ..

Further, the extraction unit 82 may extract a region in which the lane change is smoothly performed as the specific region. FIG. 6 is a diagram for explaining extraction of a specific area in which the lane change is smoothly performed. The illustrated example shows the trajectory of the vehicle acquired at a predetermined sampling interval when the predetermined vehicle changes lanes from the lane L1 to the lane L2. FIG. 6A shows an area where the lane change is not smoothly performed, and FIG. 6B shows a specific area where the lane change is smoothly performed.

For example, the extraction unit 82 selects two continuous trajectories close to the lane markings (the lane markings that divide the lanes L1 and L2) and generates a vector based on the selected two trajectories. Then, the extraction unit 82 derives an index indicating the smoothness of the lane change based on the size of the angle formed by the vector and the lane marking and the acceleration of the vehicle. For example, the index described above is derived with a tendency that the smaller the angle formed or the smaller the acceleration of the vehicle, the smaller the index.

In the illustrated example, the vector V# generated by the trajectories P# and P+1# in FIG. 6B has a different angle from the vector V# generated by the trajectories P and P+1 in FIG. 6A. The acceleration is small. Therefore, the area of FIG. 6B is extracted as the specific area.

Note that the extraction unit 82 may derive an index indicating the smoothness of the lane change for each section of the road and compare the indices to extract an area in which the lane change can be smoothly performed as the specific area. For example, on a road connected to an intersection, an index corresponding to a section before a first distance (for example, several hundred meters) from the intersection and an index corresponding to a section before a second distance (for example, 1 km) from the intersection An area that is compared and has a large index may be set as the specific area.

Further, in the example described above, the weather disaster information 42 may be used when the specific region is extracted. In this case, the extraction unit 82, for example, based on the position of the positioning device 10 recognized based on the position specified by the positioning device 10, information indicating the behavior of the vehicle, and the weather disaster information 42, The specific area in which the vehicle is recommended or not recommended may be extracted at the lane level of the road. More specifically, the extraction unit 82 changes the criterion determined as the specific region based on the weather disaster information 42. In a case where it is determined whether or not the weather condition (rain, snow, temperature drop, strong wind) that influences when the vehicle travels on the road is the specific region, for example, the extraction unit 82 , Lower the criterion for determining a specific area. As a result, when the weather condition that affects the vehicle traveling on the road does not occur, the weather condition that affects the vehicle traveling on the road occurs even if it is not extracted as the specific area. In some cases, it may be extracted as a specific area. As a result, a hydroplaning phenomenon, a road surface freeze, a region where a vehicle is likely to slip such as black ice burn, etc. are more accurately extracted as the specific region. The meteorological conditions that affect when the vehicle travels on the road are, for each region, a condition obtained from the result of actual observation in advance or a condition obtained by an experimental method.

[Processing of guidance information generation device]
Figure 7 is a flow chart showing the flow of processing executed by the guide information generator 90. First, the route generation unit 92 waits for a route generation request from the user (step S300). When a route generation request is acquired from the user, the route generation unit 92 derives the route of the designated section (step S302). Next, the guide information generation unit 94 generates guide information that is information for allowing the user to recognize the specific area when traveling on the route generated by the route generation unit 92 (step S304).

Next, the guide information generation unit 94 determines whether or not a specific area exists in the area guided by the guide information (step S306). When the specific area exists in the area guided by the guide information, the guide information generation unit 94 generates the specific guide information in consideration of the specific area, and returns to step S306 (step S308). The specific guidance information is information output to the user when traveling in a specific area.

When the specific area does not exist in the area to be guided by the guide information (when the specific guide information is generated for all the specific areas), the guide information generation unit 94 determines whether all the guide information and the specific guide information are generated. The determination is made (step S310). When all the guide information and the specific guide information are not generated, the process returns to step S306. When all the guidance information and the specific guidance information are generated, the guidance information generation device 90 transmits the generated route, the guidance information, and the specific guidance information to the vehicle that has transmitted the route generation request (step S312). This completes the processing of one routine in this flowchart. Through the above-described processing, the specific guidance information output when approaching the specific area is generated.

[Processing of navigation device]
Figure 8 is a flow chart showing the flow of processing executed by the navigation device 98. Note that this processing may be executed by the control unit 24 of the position positioning device 10. First, the navigation device 98 determines, based on the information generated by the guidance information generation device 90, whether or not a guidance start instruction has been issued (step S400). When the guidance start instruction is given, the navigation device 98 guides the vehicle based on the generated route and guidance information (step S402). For example, the route to the destination and the guidance information are displayed on the display unit provided in the vehicle.

Next, the navigation device 98 determines whether the vehicle has approached the specific area (step S404). When the vehicle approaches the specific area, the navigation device 98 displays the information of the specific area on the display unit (step S406). Next, the navigation device 98 guides the vehicle using the specific guidance information corresponding to the specific area in step S406, and returns to the processing in step S404 (step S408). When the vehicle approaches the specific area, the navigation device 98 determines whether the vehicle has arrived at the destination (step S410). When the vehicle arrives at the destination, the process of one routine of this flowchart ends. By the processing described above, the specific guidance information is output when the vehicle approaches the specific area, so that the user can recognize the existence of the specific area and control the vehicle.

In the example described above, the navigation device 98 outputs the guidance information and the specific guidance information to the user, but the control unit 24 of the position positioning device 10 displays the guidance information and the specific guidance information in the display unit 28. May be displayed on the screen, or may be output as sound from a speaker.

FIG. 9 is a diagram showing an example of the image IM displayed on the display unit. As shown, the specific area AR1 is assumed to exist in the lane L1. For example, when the vehicle M is traveling in the lane L1 and the vehicle reaches a position at a predetermined distance from the specific area AR1, the navigation device 98 displays, for example, "the specific area is XX meters ahead. Please change lanes." The specific guidance information "." and the position of the specific area AR1 are displayed on the map in an overlapping manner, or the specific guidance information is notified by voice using a speaker. Thereby, the occupant of the vehicle can avoid traveling in the specific area.

Further, in the example shown in FIG. 9, when the vehicle M is traveling in a lane L2 different from the lane in which the specific area exists, when the vehicle reaches a position at a predetermined distance from the specific area AR1, the navigation device 98 For example, the specific guidance information "There is a specific area at XX meters ahead. Please do not change lanes" and the position of the specific area AR1 are displayed on the map, or the specific guidance information is spoken using a speaker. You may be notified. Thereby, the occupant of the vehicle can avoid traveling in the specific area.

FIG. 10 is a diagram showing an example of the image IM1 displayed on the display unit. As illustrated, it is assumed that the specific area AR2 and the specific area AR3 exist in the lane L1. The specific area AR2 is an area in which the lane change can be smoothly performed, and the specific area AR3 is an area in which the lane change cannot be smoothly performed.

For example, when the vehicle M is traveling in the lane L1 to reach the destination G and the vehicle arrives at a position of a predetermined distance from the specific area AR2, the navigation device 98 displays, for example, “the specific area AR2 changes lanes. It is an area where you can go smoothly. It is recommended to change lanes.” Specific guidance information and the position of the specific area AR2 are displayed on the display part by overlapping them on the map, or a specific guidance is made using a speaker. Send information by voice. In addition, at this time, the navigation device 98 causes the display unit to display the specific guidance information "The specific area AR3 is an area in which the lane cannot be changed smoothly. It is not recommended to change the lane." Or use a speaker to notify by voice. Thereby, the occupant of the vehicle can change the lane in an area where the lane can be changed smoothly.
