Next, the operation will be described.
FIG. 2 is a flowchart showing the operation of this guidance route search system.
The operation will be described below according to this flowchart.
First, the CPU of the navigation apparatus 1000 executes a destination setting process by the destination setting means 31 (step S1). In this destination setting process, the destination setting means 31 prompts the driver to select a destination setting method based on registration information, map information, a telephone number, etc. As a result, the destination setting method selected by the driver is changed to the destination setting method. Accordingly, the destination setting screen is output to the display, and the destination is set by taking in the input information by the operation performed by the driver according to the destination setting screen.
Subsequently, a reciprocal trip necessity determination process is executed (step S2). In this round trip necessity determination process, the route to be guided is a round trip that travels from the current position to the destination and returns from the destination to the current position, or from the current position to the destination. It is determined whether the trip is a one-way trip that does not return to the position. Whether the trip is a reciprocating trip or a one-way trip is determined from a trip selection operation performed by the driver on the selection screen output to the display.
Next, the route search unit 3 searches the map data for the guide route to the destination set in step S1 (step S3). If a round trip is selected in step S2, the route returns to the current position via the destination, so the guide route to be searched is the outbound route from the current location to the destination and the route from the destination to the current location. It will be a return trip.
When the guide route to the destination is searched, the distance to the destination is calculated (step S4). When the round trip is selected in step S2, the distance from the current position to the current position again via the destination is calculated on the map data.
Next, the cruising distance calculation unit 16 calculates the current cruising distance from the remaining battery capacity detected by the battery management unit 8 (step S5). The cruising range is calculated from the remaining battery capacity detected by the battery management unit 8 and the power consumption of the electric vehicle.
Subsequently, the distance determination unit 7 of the navigation device 1000 determines whether or not the cruising distance calculated by the cruising distance calculation unit 16 exceeds the distance to the destination calculated in step S4 (step S6). .
This step S6 corresponds to the distance determining means of claim 1.
As a result, if the cruising distance exceeds the distance to the destination, it is determined that the vehicle can travel to the destination with the current remaining battery capacity, and the guidance route searched in step S3 on the map data is displayed on the display. The data is output and presented to the driver (step S7).
On the other hand, if the cruising distance is less than the distance to the destination in step S6, the charging station search unit 9 of the navigation device 1000 searches for a plurality of charging stations around the guide route to the destination searched in step S3. (Step S8).
This step S8 corresponds to the retrieval means of claim 1.

FIG. 3 is an explanatory view showing an example of a plurality of charging stations searched by the charging station searching unit 9 by the guidance route searching system of this embodiment.
In FIG. 3, reference numeral 101 denotes a current position, reference numeral 102 denotes a destination, and reference numeral 121 denotes a guide route. Reference numerals 112, 113, 115, and 116 denote charging stations around the guide route, the charging stations 115 and 116 are charging stations that are charged by a 100-volt power source, and the charging stand 113 is a charging stand and a charging stand that are charged by a 200-volt power source. Reference numeral 112 denotes a quick charging stand.
Next, the route search unit 3 of the navigation device 1000 searches for a guide route to the destination via each charging station searched in step S8 (step S9).
This step S9 corresponds to the search means of claim 1.
In this case, when a plurality of charging stations exist in a certain distance range, the charging station with the highest priority is selected in the order of the quick charging station, the 200-volt charging station, and the 100-volt charging station. In the example shown in FIG. 3, the guide route 200 reaching the destination 102 via the charging station 112 and the guidance route 300 reaching the destination 102 via the charging station 113 are searched in step S9. Yes. The cruising distance is calculated from the remaining battery capacity and the electricity consumption of the electric vehicle. Therefore, when the remaining battery capacity is low, the remaining battery capacity runs out before moving from the current position to the next charging station on the guide route. It becomes a state. Therefore, with respect to the guide route 200 and the guide route 300 via the charging station, the distance determination unit 7 determines whether there is a charging station that can travel from the current position 101 with the current remaining battery capacity (step S10). . In the example shown in FIG. 3, the cruising distance for the guide route 200 is indicated by reference numeral 201. Further, the cruising distance for the guide route 300 is indicated by reference numeral 301. In the example shown in FIG. 3, there is no charging station that can travel from the current position with the current remaining battery capacity. In other words, since “the cruising distance by the current remaining battery capacity” <“the distance from the current position 101 to the next charging station”, the charging station search unit 9 adds charging stations around the current position as shown in FIG. Search is performed (step S11).
This step S9 corresponds to the search means of claim 1.
FIG. 4 is an explanatory diagram showing an example of a plurality of charging stations additionally searched around the current position by the guidance route search system of this embodiment.
As shown in FIG. 4, the charging station 121, the charging station 123, the charging station 122, and the charging station 123 are additionally searched by the charging station searching unit 9 as charging stations around the current position 101. The charging stand 121 is a charging stand using a 100 volt power source, the charging stand 123 is a 200 volt power source, and the charging stand 122 is a charging stand capable of rapid charging.

Then, returning to step S9, the route search unit 3 searches the additionally searched route for the guide route via the charging station, and subsequently, the guide route searched in step S9 can travel from the current position 101 with the current remaining battery capacity. It is determined whether or not there is a next charging station (step S10).
In the example illustrated in FIG. 4, in step S <b> 9, the additionally searched guidance route 400 via the charging station 121, the guidance route 500 via the charging station 122, and the guidance route 600 via the charging station 123 are retrieved. . The cruising distance that can travel with the current remaining battery capacity for the guide route 400 is indicated by reference numeral 401, the cruising distance for the guide route 500 is indicated by reference numeral 501, and the cruising distance for the guide route 500 is indicated by reference numeral 501. Has been. The next charging stations that can travel from the current position 101 with the current remaining battery capacity are the charging station 121 in the guidance route 400, the charging station 122 in the guidance route 500, and the charging station 123 in the guidance route 600. Therefore, since the next charging station that can travel from the current position 101 with the current remaining battery capacity exists in any of the guide route 400, the guide route 500, and the guide route 600, the vehicle travels with the current remaining battery capacity in step S10. It is determined that there is a possible charging station, and the process proceeds to step S12.
Note that for a guidance route that is determined in step S10 that there is no charging station that can travel with the current remaining battery capacity, a new charging station can be traveled with the current remaining battery capacity around the current position. Repeat until additional charging stations are searched.

In step S12, in order to travel to the destination with the current remaining battery capacity for each guide route that is determined to have a charging station capable of traveling with the current remaining battery capacity from the current position 101 in step S10. The insufficient power amount calculation unit 11 calculates the insufficient power amount.
This step S12 corresponds to the insufficient power amount calculating means of claim 1.
The calculation of the insufficient electric energy is performed as follows.
FIG. 5 is an explanatory diagram showing an example of a plurality of charging stations additionally searched from the current position to the destination by the guidance route search system of this embodiment.
The amount of electric power that is insufficient to travel to the destination 102 with respect to the charging station 121 of the guide route 400 is the remaining battery capacity when the charging station 121 arrives when traveling from the current position 101 to the charging station 121 with the current remaining battery capacity. Pw, where Fw is the battery capacity required to travel from the charging station 121 to the destination 102, the battery capacity that is insufficient to travel to the destination 102 when the charging station 121 arrives is Fw-Pw. This is the required capacity of the battery that needs to be charged at the charging station 121 at the minimum in order to travel to the destination 102 according to the guide route 400 when the station 121 arrives.
Further, the amount of electric power that is insufficient to travel to the destination 102 for the charging station 122 of the guide route 500 is determined by the remaining battery capacity when the charging station 122 arrives when traveling from the current position 101 to the charging station 122 with the current remaining battery capacity. If the capacity is Qw and the battery capacity required to travel from the charging station 122 to the destination 102 is Gw, the battery capacity that is insufficient to travel to the destination 102 when the charging station 122 arrives is Gw−Qw. Is a required capacity of a battery that needs to be charged at the charging station 122 at the minimum in order to travel to the destination 102 according to the guide route 500 when the charging station 122 arrives.
In addition, the amount of electric power that is insufficient to travel to the destination 102 for the charging station 123 on the guide route 600 is determined by the remaining battery capacity when the charging station 123 arrives when the current battery 101 travels from the current position 101 to the charging station 123. When the capacity is Rw and the battery capacity required to travel from the charging station 123 to the destination 102 is Hw, the battery capacity that is insufficient to travel to the destination 102 when the charging station 123 arrives is Hw−Rw. Is the required capacity of the battery that needs to be charged at the charging station 123 at the minimum in order to travel to the destination 102 according to the guide route 600 when the charging station 123 arrives.

In the following step S13, for each guide route, for the guide route 400, the amount of power that can be charged at the charging station 121 when it arrives at the charging station 121, and for the guide route 500, the power that can be charged at the charging station 122 when it arrives at the charging station 122. For the guidance route 600, the amount of power that can be charged at the charging station 123 when the charging station 123 arrives is calculated. For example, when the battery capacity when the battery is in a fully charged state is Mw and the remaining battery capacity when the battery arrives at the charging stand 123 is Nw, Mw−Nw is the amount of power that can be charged.
The calculation of the insufficient electric energy in step S12 and the calculation process of the chargeable electric energy in step S13 are executed for each charging station for each guide route.
That is, in the example shown in FIG. In the guidance route 500, the charging station 122 is executed. In the guidance route 600, the charging stand 123 is executed.

In subsequent step S14, the chargeable power amount calculation unit 12 determines for each guide route whether or not charging of insufficient power is possible.
This step S14 corresponds to the determination means of claim 1.
As a result of the calculation process of the chargeable electric energy at the time of arrival at the charging station in step S13, for example, when the electric energy that is insufficient to travel to the destination in step S12 on the charging station 121 with respect to the guide route 400 cannot be charged 100%. In step S19, the charging station search unit 9 additionally searches for a new charging station that additionally passes through the charging station 121 that is determined to be unable to be charged with insufficient power in the vicinity of the path 400 and the charging station 121.
This step S19 corresponds to the retrieval means of claim 1.
FIG. 6 is an explanatory diagram showing an example of the charging station 115 additionally searched near the route 400.
When the charging station 115 is newly searched in the vicinity of the route 400 where it is determined that the insufficient amount of power cannot be charged 100%, the route search unit 3 causes a new guide route 700 as a guide route from the current position 101 to the destination 102. Is searched and set, and the distance between the charging stations when the route passes through the new guide route 700 is calculated (step S21), and the process returns to step S12.
This step S21 corresponds to the search means of claim 1.
And the process of step S12, step S13, and step S14 is repeated about the new guidance path | route 700 containing the charging station 115 newly newly searched.
As a result, when it is determined that charging of insufficient power is possible at each charging station of the guidance routes 500, 600, 700, charging of the guidance routes 500, 600, 700 determined that charging of the insufficient power is possible. The charging time information of the stand is received from the charging station information providing system by the in-vehicle communication device 15 (step S15).

Subsequently, the charging time calculation unit 13 calculates the charging time of the required capacity of the battery for each charging station of the guide routes 500, 600, and 700 (step S16).
Step S16 corresponds to the charging time calculation means of claim 1.
The calculation of the required capacity charging time is performed as follows.
The charging capacity of the battery differs depending on the type of charging stand, that is, whether the charging stand is a quick charging stand, a charging stand with a 200 volt power supply, or a charging stand with a 100 volt power supply, and the charging time is also different. Come different. The required battery capacity is the remaining battery capacity at the time of arrival at the charging station, which is insufficient to travel to the destination or the next charging station, and the time required for charging the required capacity of this battery is charged for that charging station. It will be time. For this reason, if the charging capacity of the charging station is Sw / hour, the charging time is (insufficient battery capacity) / S.
Next, the travel time calculation means 32 calculates the travel time required to travel from the current position 101 to the destination 102 for each guide route determined to be capable of charging the insufficient power (step S31).
Then, in the required time calculation unit 14, in addition to the calculated travel time, each of the guide routes 500, 600, from the charging waiting time information acquired in step S15 and the charging time of the required electric energy calculated in step S16. The required time for every 700 is calculated (step S17).
Step S17 corresponds to the required time calculation means of claim 1.
The required time at each charging station for each guidance route 500, 600, 700 calculated in step S17 is set as a charging station charging table for each guidance route (step S28).
FIG. 7 is an explanatory view showing the charging stand charging table TBL. The charging stand charging table TBL includes a waiting time and charging time at a charging station that passes through the guide route from the current position 101 to the destination 102 and each charging station, and waiting time and charging time at all charging stations that pass through the charging stand. And the required time, which is the sum of travel time, is recorded.
Next, the route search unit 3 selects and presents the guide route having the shortest required time among the required times in the charging station charging table calculated in step S17 (step S29).
This step S29 corresponds to the selection means of claim 1.
