  By the way, when a plurality of drivers travel to a destination while changing driving, driving is often changed in facilities such as roadside stations, service areas, and parking areas. In that case, it is desirable to determine a facility as a place to change driving in consideration of driving habits and driving characteristics such as average fuel consumption. For example, when driving on a route that includes a highway and driving to a driver who can drive with good fuel efficiency on the highway, the driving distance of the driver on the highway is reduced in order to reduce fuel consumption. You should decide where to change driving so that it gets longer. However, in the technique described in Patent Document 1 described above, the driving characteristics of the driver are not taken into account when setting a section, that is, a point where driving is changed, on the route from the starting point to the destination.

  According to a third aspect of the present invention, in the navigation device according to the second aspect, the travel section setting means first selects candidate facilities that reduce fuel consumption in the entire travel route based on the average fuel consumption of a plurality of drivers. The gist is that it is set as a two-division point, and a section divided by the second division point is set as a traveling section.

  The navigation method according to claim 4 includes a step of acquiring a travel route, a step of setting a plurality of travel sections into which the travel route is divided based on driving characteristics of a plurality of drivers stored in the driving characteristic storage means, The gist is to have a step of assigning a driver in charge of driving to a plurality of travel sections and a step of guiding the driver in charge of the plurality of travel sections together with the travel route.

Means.
Details of processing executed by each component of the control unit 26 will be described later.

(Route guidance processing)
A route guidance process executed by the control unit 26 of the navigation device 1 configured as described above will be described below. FIG. 4 is a flowchart showing the entire route guidance process executed by the navigation device 1 (steps are abbreviated as “S” in the description of each process below). This route guidance process is activated when the vehicle starts to travel. For example, it is automatically started when the engine is started or when the navigation apparatus 1 is turned on.

After starting the route guidance process, the control unit 26 causes the travel route acquisition unit 261 to process a destination and a plurality of drivers (hereinafter referred to as “co-drivers”) heading to the destination via the operation unit 24. And waits for input by the user (S1). The method of inputting information for specifying the destination is arbitrary. For example, the destination address or facility name can be input via the operation unit 24, or an arbitrary point in the map displayed by the display unit 22 can be used as the destination. It can be entered as the ground.
The input method of the riding driver is arbitrary. For example, the driver name whose driving characteristics are stored in the driving characteristic DB 212 is displayed on the display unit 22 and the driver is selected from the displayed driver names. Can be made. Alternatively, the driver name can be input by the user via the operation unit 24. In addition to this, face photos, weights, etc. are stored in advance as personal information of the driver, and the driver is judged from the information obtained from the imaging device installed in the vehicle, the load sensor of the seat, and the personal information, You may make it input automatically.

  After the destination and the passenger are input (S1, Yes), the control unit 26 determines the travel route from the departure point to the destination based on the map information 211a of the map information DB by the processing of the travel route acquisition unit 261. Search and obtain (S2). As a specific search method, a known technique such as the Dijkstra method can be used. Here, the departure point may be specified by an input by the user in the same manner as the above-mentioned destination. If there is no input, the current position detected by the current position detection unit 20 may be used as the departure point. Good.

(Tentative section setting process)
Next, the control part 26 performs the process which sets the temporary area which is a temporary travel area in a travel route by the process of the travel area setting part 262 (S3). Hereinafter, specific contents of the provisional section setting process will be described with reference to FIG. FIG. 4 is a flowchart showing the provisional section setting process executed in S3.

  When the temporary section setting process is executed, the control unit 26 determines whether or not the travel continuation degree on the travel route is high (S3-1). For example, it is determined whether or not the total travel distance from the departure point to the destination is a first predetermined distance (for example, 50 km) or more. If so, it is determined that the running continuation level is low. Alternatively, it is determined whether or not the required time from the departure point to the destination is a predetermined time (for example, 1 hour) or more. You may make it judge that a continuation degree is low. This determination will be described later based on the idea that driving should be performed by a plurality of drivers because the driving burden on the driver increases when the degree of continuation of the driving route is high. It is determined whether or not it is necessary to set a temporary section.

  When it is determined that the travel continuation degree is high (S3-1, Yes), the control unit 26 determines that it is necessary to set a temporary section, and based on the road type of the road included in the travel route, It is determined whether there is a road type switching point on the travel route (S3-2). On the other hand, when it is determined that the travel continuation degree is low (S3-1, No), the control unit 26 determines that it is not necessary to set a temporary section, and sets the entire travel route as one travel section. (S3-5), the provisional section setting process is terminated, and the process proceeds to S4.

When a road type switching point exists on the travel route (S3-2, Yes), the control unit 26 determines that the switching point should be a temporary driver change (hereinafter referred to as a first classification point). And a section divided by two points of the first divided point, the starting point, or the destination is set as a temporary section (S3-3), and the process proceeds to S3-6.
On the other hand, when the road type switching point does not exist on the travel route (S3-2, No), the control unit 26 first classifies the equally divided points obtained by dividing the travel route into a plurality of equidistant sections. It sets as a point, the area divided by two points among the said 1st division point, a departure place, and the destination is set as a temporary area (S3-4), and it transfers to S3-6.

  Then, after the temporary section is set (after the processing of S3-3 and S3-4), the control unit 26 assigns a temporary driver to the set temporary section based on the driving characteristics of the riding driver ( S3-6). Specifically, the road type of the road in the temporary section is specified, and the rider who has the best average fuel consumption as the driving characteristic associated with the specified road type is selected as the temporary driver to drive the vehicle in the temporary section. Assign as a driver. Here, a temporary driver is preferentially assigned from a section with a long distance so that one driver does not continuously take charge of a plurality of sections. Specifically, when the temporary section is set in the process of S3-2 and the driver with the best average fuel consumption is the same driver in each road type of the adjacent temporary section, the same driver has a long distance. A driver with the second highest average fuel efficiency of the road type in a section with a short distance is assigned to the section with a short distance. Alternatively, when a temporary section is set in the process of S3-4, there is only one road type in the temporary section. Therefore, the temporary driver is selected from the temporary section on the departure side in order of good average fuel efficiency in the road type. Assign as. Not only when a temporary section is set in the process of S3-4, a temporary section on the departure side may be preferentially assigned.

  By performing the above processing, a temporary driver can be assigned even when there are two or more temporary sections. When the temporary driver for the temporary section is assigned, the control unit 26 ends the temporary section setting process and proceeds to S4.

(Route guidance processing continued)
Subsequently, the control unit 26 determines whether or not a temporary section is set by the processing of the travel section setting unit 262 (S4). And when the temporary section is set (S4, Yes), that is, when the travel section is not set, it is a facility along the travel route, and the first division point set by the temporary section setting process Search for nearby candidate facilities (S5). On the other hand, when the temporary section is not set, that is, when the travel section with one travel route as a whole is set in S3-5 (S4, No), the control unit 26 proceeds to S12.

In S5, the control unit 26 is a facility along the travel route by the processing of the travel section setting unit 262, and the distance from the first segment point in each of the departure direction and the destination direction from the first segment point is determined. A facility that is less than a second predetermined distance (for example, a distance that is half of the provisional section) is searched, and the searched facility is set as a candidate facility.

Subsequently, in S6, the control unit 26 determines whether or not a candidate facility has been searched by the processing of the travel section setting unit 262, and when a candidate facility is searched (S6, Yes), there are a plurality of candidate facilities. It is determined whether or not a search has been made (S7). On the other hand, when a candidate facility is not searched (S6, No), the control part 26 sets a temporary area as a travel area by the process of the travel area setting part 262 (S11). At that time, since there is no facility as a point where the driver should be changed, guidance may be given by voice so that the driver is changed carefully in the vicinity of the first division point.
In S7, when a plurality of candidate facilities are searched (S7, Yes), the control unit 26 determines the positional relationship between the candidate facility and the first division point that is the reference for the search by the processing of the travel section setting unit 262. Is specified (S8). Here, the positional relationship is a distance from the first division point and a direction from the first division point (whether it is a departure direction or a destination direction). After identifying the positional relationship between the candidate facility and the first division point, the control unit 26 travels based on the positional relationship identified in S8 and the driving characteristics of each driver by the processing of the traveling section setting unit 262. A section is set (S9), and the process proceeds to S12.

Here, in the travel section setting process in consideration of the driving characteristics of the driver performed in S9, the travel section is set so that the fuel consumption of the entire travel route is minimized in consideration of the average fuel consumption as the driving characteristics. An example will be described in detail with reference to FIG. In FIG. 5, the figure which shows the relationship of the temporary area (in the figure, temporary area X and Y in the figure), the 1st division point (in the figure, point A), and the candidate facility (in the figure, facility α and facility β) in the travel route R It is. The riding drivers are drivers A and B, driver B is assigned to temporary section X and driver A is assigned to temporary section Y, and the road types of temporary sections X and Y are general road and mountain road. Assume that the section lengths are LX and LY, and the distances between the first division point A and the facilities α and β are Lα and Lβ, respectively.

First, the control unit 26 calculates the fuel consumption of the entire travel route when the driver is changed at each candidate facility.
In the example of FIG. 5, the fuel consumption Cα (l) of the entire travel route when the driver is changed at the candidate facility α is calculated by the following equation (1).
Cα = (LX−Lα) /10.3+Lα/10.1+LY/10.0 (1)
Next, the control unit 26 calculates the fuel consumption amount Cβ (l) of the entire travel route when the driver is changed at the candidate facility β by the following equation (2).
Cβ = LX / 10.3 + Lβ / 9.5 + (LY−Lβ) /10.0 (2)

  Then, the calculated Cα and Cβ are compared, and when the driver is changed, the candidate facility with the smallest fuel consumption of the entire travel route is set as the point where the driver should be changed (hereinafter referred to as the second division point). A section divided by the second division point is set as a traveling section. Specifically, when Cα> Cβ, the fuel consumption is greater when the driver is changed at the candidate facility α than when the driver is changed at the candidate facility β. Set as a bisection point. On the other hand, if Cα <Cβ, the fuel consumption is higher when the driver is changed at the candidate facility β than when the driver is changed at the candidate facility α. Set as a point. And the section divided by the 2nd division spot is set as a run section.

When a temporary section is set in the process of S3-4, there is only one road type in the temporary section, and the passengers who are traveling in the order from the temporary section on the departure side in the order of good average fuel consumption in the road type. Because of the allocation, the longer the driving charge distance of the driver in charge on the departure side, the lower the overall fuel consumption. Therefore, in this case, a candidate facility in the direction of the destination from the first segment point is set as a candidate facility (second segment point) to be replaced by the driver.

On the other hand, when a plurality of candidate facilities are not searched (S7, No), that is, when only one candidate facility is searched, the control unit 26 performs a search by the process of the travel section setting unit 262. The section divided by the one candidate facility thus set is set as the traveling section (S10), and the process proceeds to S12. Note that when setting the travel section, guidance may be given by voice or the like so as to change driving by one candidate facility found.

In addition, although the process from the above-mentioned S5 to S10 was explained about one first division point (in the case of two provisional sections), even when there are three or more provisional sections, the first division point on the departure side in order. Then, the same process as in the case of two temporary sections is performed to set a travel section.

  As described above, after the travel section is set in S3-5, S9, S10, or S11, the control unit 26 performs the process in the driver assignment unit 263 on each travel section with respect to the set travel section. A driver in charge of driving is assigned (S12). Specifically, when a travel section is set in S3-5, since the road types of the roads in the travel section are all the same, the driver with the highest average fuel consumption is assigned as the responsible driver in the road type. . In addition, when the travel section is set in S9 and S10, the distance of each travel section is changed with respect to the temporary section, but the order of the driver in charge of driving and the departure side of each driver is changed. Therefore, the temporary driver assigned to the temporary section on the departure side is assigned as the assigned driver in order from the traveling section on the departure side.

  As described above, after the driver in charge is assigned to the travel section, the control unit 26 performs the processing of the route guide unit, along with the travel route, the driver in charge for each travel section and the travel section, the second division point (driver) The candidate facility to be replaced is guided to the driver via the display unit 22 and the speaker 23 (S13).

(effect)
As described above, according to the present embodiment, a plurality of traveling sections that divide the traveling route are set based on the traveling route and the driving characteristics of the plurality of drivers, and the driver in charge of driving in the set traveling section. And guide the driver in charge of a plurality of travel sections along with the travel route. For this reason, when the travel route is guided, it is possible to guide the travel section in consideration of the driving characteristics of each driver together with the driver in charge of each travel section. Therefore, the user can know an appropriate travel section in consideration of the driving characteristics of each driver and a point where the driving is changed.

  In addition, since the driving section is set based on the positional relationship between the candidate facility along the driving route and the first division point and the driving characteristics of the plurality of drivers, the position of the candidate facility along the driving route and the driving of the plurality of drivers are set. It is possible to set a travel section in consideration of characteristics.

  In addition, considering the average fuel efficiency of each road type as driving characteristics and setting the driving section as the second division point with the candidate facility with the smallest fuel consumption in the entire driving route, the fuel consumption in the entire driving route It is possible to set the travel section so as to minimize the.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

  First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

  Further, each of the electrical components described above is functionally conceptual and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution and integration of each component is not limited to that shown in the figure, and all or a part thereof can be configured functionally or physically distributed or integrated in arbitrary units. For example, a part of the navigation device 1 (the storage unit 21 and the control unit 26) is provided in the information distribution center, connected to the information distribution center via the communication unit 25, and acquired at the information distribution center. The set travel route, travel section, and driver in charge may be received and guided.

  In the above-described embodiment, the driving section is set in consideration of the average fuel consumption for each road type as the driving characteristics. However, the driving characteristics are not particularly limited to the average fuel consumption for each road type, and include various characteristics. I can do it. For example, there are a driving frequency for each road type (driver's preference), a poor / unprofitable person for each road type, and a safe driving index for each road type.

  Here, the case where the driving characteristic is a safe driving index for each road type will be described more specifically in comparison with the above-described embodiment. In this case, the driving characteristic DB (see FIG. 2) stored in the storage unit 21 stores the item “safe driving index” for each small road type instead of the item “average fuel consumption (km / l)”. The safe driving index is, for example, an integer of 5 levels from 1 to 5, and the larger the number, the safer the driving.

In the temporary driver assignment process in S3-6, when a temporary section is set in S3-3, a driver having a large number of safe driving indexes as driving characteristics is assigned as a temporary driver in the temporary section. You may do it. In the travel section setting process based on the positional relationship of S9, in the example of FIG. 5 described above, the fuel consumption amount of the entire travel route is calculated in consideration of the average fuel consumption as the driving characteristic, and the fuel consumption of the entire travel route is calculated. Although the candidate facility with the smallest amount is set as the second division point, when considering the safe driving index as the driving characteristic, for example, the safe driving index of the entire driving route is calculated, and the calculated driving route of the entire driving route is calculated. A candidate facility having the largest safe driving index may be set as the second division point.

In S3-3, the section classified by the road type switching point is set as a temporary section, but only when the distance of the temporary section is equal to or greater than a third predetermined distance (for example, 10 km). A determination condition may be added so that a temporary section is set according to the switching point.
