  By the way, with the recent development of the expressway network, in the expressway network to which a common toll system is applied, there are increasing cases in which a plurality of routes exist from a certain entrance IC (interchange) to the exit IC. ing. For example, as shown in FIG. 1, when the entrance IC is the “Ota Kiryu” IC on the Kita Kanto Expressway and the exit IC is the “Sutama” IC on the Chuo Expressway, the “Ota Kiryu” IC is connected to the North Kanto Expressway. Route R1 via the road, Kanetsu Expressway and Ken-O Expressway to Chuo Expressway “Suda” IC, and “Ota Kiryu” IC to Kita Kanto Expressway, Joshinetsu Expressway and Nagano Motor There is a route R2 via the Nagano Expressway that leads to the “Sutama” IC on the Chuo Expressway.

  The usage fee (highway toll) on the expressway (toll road) is generally higher as the travel distance is longer as described above. However, if the entrance IC and the exit IC are the same, the route may be different. May be the same. For example, according to the site provided by East Japan Expressway Co., Ltd. (NEXCO East Japan), the highway fare from the above-mentioned Kita Kanto Expressway “Ota Kiryu” IC to the Chuo Expressway “Sutama” IC Even if it is route R1 (222.8 km) or Nagano route via route R2 (281.9 km) that is longer than the central route via route R1, it is the same “¥ 6,050”. In this way, if the entrance IC and the exit IC are the same, the high-speed fee is the same even on different routes. In some cases, the high-speed fare to the exit IC will be lower. For example, in the case of the route through the central route R1 and the route through the Nagano road R2 shown in FIG. 1, as shown in FIG. Because the mileage is short, the fare is lower than the high-speed fare to “Suda” IC (¥ 6,000). Even if the mileage is long, the usage fee to the “Suda” IC is similarly lower (¥ 6,000), and the route R1 via Ken-O Expressway leads to the “Amagasaki” IC just before the “Suda” IC. Because the mileage is short, the fare is lower than the high-speed fare to the “Suda” IC (¥ 5,900), but the high-speed fare to the “Amagasaki” IC next to the “Suda” IC on the route R2 via Nagano Even if the mileage is long, the high-speed charge to the “Suda” IC is the same Is a small amount (\ 5,900) (from the site provided by the East Expressway Company Limited).

  When the route obtained by the route search in the navigation device includes an expressway (toll road), as described above, the route to the expressway exit IC (search route exit IC) in the route obtained by the route search is as described above. Information that the high-speed charge to the next exit IC of the search route exit IC is lower than the high-speed charge is, for example, a user who is not particularly urgent to the destination or a user who wants to enjoy driving on the highway. It may be useful for such as.

  The present invention has been made in view of such circumstances, and provides a navigation device capable of providing more useful information about toll road usage fees.

The navigation device according to the present invention is a navigation device that guides a vehicle according to a route obtained by a route search from a current position to a destination, and a toll road is included in the first route obtained by the route search. In addition, a first fee acquisition means for acquiring a usage fee to the exit of the search route that is an exit of the toll road as a first fee, and the first route from the current position to the search route exit is different from the first route, When there is another route including a toll road that has the same fee as the one fee, the usage fee to the next exit of the search route exit that is the exit of the toll road included in the first route is used as the second fee. A second charge acquisition means for acquiring; a charge comparison determination means for determining whether or not the second charge is lower than the first charge; and the second charge is determined by the charge comparison determination means. When it is determined that the small amount from the fee, a structure and a determination result presentation means for presenting predetermined information based on the determination result.

  With such a configuration, the first fee (usage fee) to the toll road search route exit included in the route obtained by the route search is compared with the second fee to the next exit of the toll road. When the second fee is lower than the first fee, predetermined information based on the determination result is presented. The user can know that the usage fee is lower when going from the search route exit of the toll road included in the route obtained by the search to the next exit according to the presented predetermined information.

  In the navigation device according to the present invention, the determination result presenting means may be configured to present at least information about the first fee and the second fee as predetermined information based on the determination result.

  With such a configuration, the first fee that is the usage fee to the toll road search route exit included in the route obtained by the search and the second fee that is the usage fee to the next exit of the search route exit are Since it is presented, the user can specifically grasp the difference between the charges.

  In the navigation device according to the present invention, means for acquiring a second route by searching for a route to the destination via the search route exit and the next exit of the toll road according to an operation at an operation unit. The first required time presenting means for acquiring and presenting the first required time when passing through the first route, and the second required for acquiring and presenting the second required time when passing through the second route It can be set as the structure which has a time presentation means.

  With such a configuration, the first required time when passing through the first route obtained by the original search route, and the second route that is the route to the destination via the search route exit and the next exit Since the second required time at the time of passing is presented, the user can determine the resetting of the route based on the time difference and the time.

  Further, the navigation device according to the present invention may have a configuration including guidance route setting means for setting the second route as a route to guide the vehicle in accordance with an operation on the operation unit.

  With such a configuration, the second route, which is the route to the destination via the search route exit and the next exit, can be easily reset as a route to guide the vehicle.

  According to the navigation device of the present invention, the first fee (usage fee) to the toll road search route exit included in the route obtained by the route search and the second fee to the next exit of the toll road. If the second charge is lower than the first charge, predetermined information based on the determination result is presented. Therefore, more useful information about the toll road charge is displayed. Can be provided.

  An embodiment of the present invention will be described with reference to the drawings.

  The navigation device according to the present invention is configured as shown in FIG.

  In FIG. 3, the navigation device 100 has a processing unit 11 constituted by a computer unit (including a CPU). The processing unit 11 is connected to a navigation sensor group 17 such as a GPS receiver, an acceleration sensor, a wheel speed sensor, and a gyro, and a storage unit 14 (for example, a hard disk drive). The storage unit 14 stores various information necessary for processing in the processing unit 11, for example, information necessary for navigation processing such as map information, highway toll tables, information on facilities, and the like. The processing unit 11 includes an LCD or the like, and includes a display unit 13 that displays various types of information, a touch panel on the display unit 13, operation buttons, and the like, and is used to input processing instructions and various types of information. An output circuit 15 connected to the operation unit 12 and the speaker 16 is connected. The processing unit 11 performs processing for searching for a route to a facility designated as a destination by operating the operation unit 13 based on map information stored in the storage unit 14, information on the facility, and the like, and a route obtained by the search. When a highway (toll road) is included, processing such as calculation of the usage fee (highway fee) is performed. The processing unit 11 detects the position of the vehicle based on various detection signals from the navigation sensor group 17, and uses the detected position information and map information to detect the vehicle along the route obtained by the search. Navigation processing (route guidance) is performed to guide the facility. Then, the processing unit 11 displays a mark indicating the position of the vehicle along with the map on the display unit 13 by the navigation process, so that voice guidance for guiding the vehicle along the route is output from the speaker 16. The audio signal is output to the output circuit 15.

  The processing unit 11 executes a process for setting a route to guide the vehicle according to the procedure shown in FIG.

  In FIG. 4, the processing unit 11 calculates the current position of the vehicle based on various detection signals from the navigation sensor group 17 and uses the map information to reach the destination specified by the operation unit 12. A route is searched under predetermined conditions (highway priority, general road priority, time priority, distance priority, etc.) (S10: route search processing). Then, the processing unit 11 uses a plurality of routes obtained by the search under different conditions as candidate routes, calculates information about the candidate routes (required time, high speed fee, distance), or map information Or from the charge table (first charge acquisition means), and the information is displayed on the display unit 13 as shown in FIG. 5, for example (S11). In FIG. 5, the display unit 13 has a window (recommended) indicating information on a recommended route having the shortest required time, and a window (general) indicating information on a route using a general road without using an expressway. ) And a window (another route) representing information on the route obtained by the search under other conditions is displayed.

  An operation in which a user (for example, a driver) selects one candidate route from a plurality of candidate routes displayed on the display unit 13 (for example, a touch operation on a window representing information on the candidate route shown in FIG. 5). Then, the processing unit 11 recognizes the selected candidate route as a selected route (S12), and makes the selected route appear clearly on the display unit 13, for example, as shown by a thick arrow shown in FIG. In this case, it is clearly indicated that the recommended route with the shortest required time is the selected route. Then, the processing unit 11 determines whether or not an expressway is included in the selected route (S13). When the selected route includes an expressway (YES in S13), the processing unit 11 passes through the exit IC (search route exit IC) of the expressway included in the selected route, and the next exit IC (next exit). IC) is acquired from the highway toll table stored in the storage unit 14 (S14: second toll acquisition means).

  When the high-speed toll to the next exit IC is acquired, the processing unit 11 allows the high-speed toll to the next exit IC to be lower than the high-speed toll for the search route exit IC that is the exit IC of the expressway included in the selected route. It is determined whether or not there is (S15: charge comparison determination means).

For example, as shown in FIG. 6, the highway section R _{HW1 (A → C)} from the entrance IC “A” to the exit IC “C” (search route exit IC) via the IC “B”, the current position ST General road R _GW1 from the highway section R _{HW1 (A → C) to} the entrance IC “A”, and from the search route exit IC “C” of the highway section R _{HW1 (A → C)} to the destination TG When the route composed of the road R _GW2 is selected as the selected route, the high-speed fee from the entrance IC “A” to the searched route exit IC “C” is acquired. Here, if there is another highway section R _{HW2 (A → C)} as a route from the entrance IC “A” to the exit IC “C”, as described above (see FIGS. 1 and 2), the selection is performed. From the highway fare to the search route exit IC “C” of the highway section R _{HW1 (A → C)} included in the route, pass through the search route exit IC “C” and further pass through the highway section R _HW11 to the next exit The high-speed charge to IC “D” may be low.

In such a case, when the processing unit 11 determines that the high-speed charge to the next exit IC “D” through the search route exit IC “C” is lower than the high-speed charge to the search route exit IC “C”. (YES in S15), a new route (ST → R _GW1 → R _{HW1 (A → C)} → R _HW11 → R _GW3 → TG) is searched through the next exit IC “D” to the destination TG (S16). : Means for acquiring the second route). The processing unit 11 calculates the distance of the new route obtained by this search and the required time when traveling on the route. The processing unit 11 then determines based on the determination result that the high-speed fee from the search route exit IC “C” to the next exit IC “D” is lower than the high-speed fee to the route search exit IC “C”. For example, as shown in FIG. 7, a guidance message that “the price of the next exit IC is cheaper than the highway exit IC of the selected route!” Is displayed on the display unit 13 (S17). In addition to the guidance message, the processing unit 11 displays a window W1 indicating information about the selected route (exit IC, required time, distance, high-speed toll), information about a new route (next exit IC, required time, distance). , And a guidance message for prompting a route change such as “Please touch the next exit IC when changing the highway exit” is displayed on the display unit 13.

Thereafter, the processing unit 11 determines whether or not the new route has been selected based on whether or not the touch operation of the window W2 corresponding to the new route displayed on the display unit 13 has been performed (S18). . When the touch operation on the window W2 corresponding to the new route is performed and the new route is selected (YES in S18), the processing unit 11 passes the exit IC “C” and the next exit IC “D”. A new route (ST → R _GW1 → R _{HW1 (A → C)} → R _HW11 → R _GW3 → TG) is set as a route to guide the vehicle (S19: guide route setting means). On the other hand, when it is determined that the new route is not selected by touching the window W1 corresponding to the selected route initially selected from a plurality of candidate routes instead of the window W2 corresponding to the new route (in S18). NO), the processing unit 11 sets the selected route (ST → R _GW1 → R _{HW1 (A → C)} → R _GW2 → TG) as a route to guide the vehicle (S20).

  When the route for guiding the vehicle is set as described above, the processing unit 11 starts processing (navigation processing) for guiding the vehicle to the destination TG according to the route set as the route to be guided.

  If the selected route does not include a highway (NO in S13), and even if the selected route includes a highway, the search route exit IC is determined based on the highway fare to the searched route exit IC. If the high-speed fare to pass to the next exit IC does not become low (NO in S15), the processing unit 11 sets the initially selected route (see S11 and S12) as the route to guide the vehicle. (S20).

  In the navigation apparatus as described above, the highway to the highway search route exit IC “C” included in the selected route selected from the plurality of candidate routes obtained by the route search, and the next highway exit IC If the high-speed fare to “D” is compared and determined, and the high-speed fare to the next exit IC “D” is lower than the high-speed fare to the search route exit IC “C”, it is based on the determination result. A guidance message “The price of the next exit IC is cheaper than the highway exit IC of the selected route!” Is displayed on the display unit 13. For this reason, the user can know from the guidance message that the highway fee is lower when going from the searched route exit IC “C” of the expressway included in the selected route to the next exit IC [D]. it can. In this way, the user can obtain more useful information about the highway usage fee.

  Also, the required time when passing through the selected route and the required time when passing through the route to the destination TG via the search route exit IC “C” and the next exit IC “D” are presented. (Refer to FIG. 7) Based on the time difference and the time, the user can determine the resetting of the route.

  Further, by selecting the window W2 for the route to the destination TG via the searched route exit IC “C” and the next exit IC “D”, the searched route exit IC “C” and the next exit IC are selected. The route from “D” to the destination TG can be easily set as a route to guide the vehicle.

  For example, when the selected route is set as a route to guide the vehicle without performing processing for setting a route via the next exit IC, the vehicle guided according to the selected route (recommended route) travels. In this case, the processing unit 11 can perform processing according to the procedure shown in FIG.

  The processing unit 11 determines whether or not the highway is included in the route on which the vehicle is to be guided (S31). If the route on which the vehicle is to be guided includes an expressway (YES in S31), the processing unit 11 performs processing (route to guide the vehicle to the destination TG according to the route set as the route on which the vehicle is to be guided. While performing guidance processing (navigation processing) (S32), based on various detection signals and map information from the navigation sensor group 17, it is confirmed whether or not the vehicle has entered the expressway from the entrance IC “A” (S33). When the vehicle enters the highway (YES in S33), the processing unit 11 stores the highway charge up to the next exit IC “D” of the search route exit IC “C” of the highway in the storage unit 14. Obtained from the table (S34). Then, the processing unit 11 determines whether or not the high-speed charge to the next exit IC “D” is lower than the high-speed charge to the search route exit IC “C” (S35).

  When the high-speed fare to the next exit IC “D” is lower than the high-speed fare to the search route exit “C” (YES in S35), the processing unit 11 displays, for example, as shown in FIG. 13, together with the high-speed fee to the search route exit IC “C” and the distance from the current location to the search route exit IC “C”, the high-speed fee to the next exit IC “D” and the next exit IC “ The IC information window 13a representing the distance to “D” is displayed as a guidance display (S36). Thereafter, the processing unit 11 continues the route guidance processing (navigation processing) while confirming whether or not the vehicle has arrived at the vehicle TG (S38). Then, when the vehicle arrives at the destination TG, the processing unit 11 ends the process related to route guidance.

  According to the route guidance processing as shown in FIG. 8, the user can guide the route that the vehicle is currently guided by using the IC information window 13a (guidance display) displayed on the display unit 13 as shown in FIG. It is possible to know that the highway fee is lower when going from the search route exit IC “C” to the next exit IC [D]. Then, the user advances the vehicle toward the next exit IC “D” as it is, instead of moving the vehicle from the search route exit IC “C” of the expressway to be guided to the general road, for example, A new route to the destination TG via the next exit IC “D” is set by the route resetting function of the navigation device. Then, the vehicle is guided to the destination according to the new route.
