  The mode selection unit 173 allows the user to select the current location mode or the destination mode via the input unit 11. Here, the current location mode is a mode for acquiring information related to the amount of energy supply necessary for traveling from the current location to a desired cruising range. The destination mode is a mode for acquiring information relating to the amount of energy supply required for traveling from the destination to a desired cruising range. In addition, when the destination mode is selected, the user is caused to input desired destination information via the input unit 11.

  Based on the vehicle information acquired by the vehicle information acquisition unit 12, the post-charge cruising range calculation means 174 changes the cruising range after energy supply from the current remaining energy level to the full amount of energy (full charge). Up to a predetermined amount of energy supply. Information indicating the cruising range (the cruising range after charging) at each energy supply amount calculated by the post-charging cruising range calculation unit 174 is output to the post-charging cruising range drawing unit 176.

  The destination arrival availability determination unit 178 includes destination information input by the user via the input unit 11, vehicle information acquired by the vehicle information acquisition unit 12, current location information acquired by the current location information acquisition unit 13, and a storage unit 16 is used to determine whether it is possible to reach the destination from the current location with a full amount of energy based on the map DB 161 or the like stored in FIG. The destination arrival availability determination means 178 first calculates the amount of energy required to travel from the current location to the destination. Then, the difference between the required energy amount and the full amount of energy is calculated, and it is determined whether the destination can be reached from the current location with the full amount of energy.

  The post-arrival cruising range calculation means 179 includes destination information input by the user via the input unit 11, vehicle information acquired by the vehicle information acquisition unit 12, current location information acquired by the current location information acquisition unit 13, and storage. Based on the map DB 161 and the like stored in the unit 16, the cruising range from the destination is calculated for each predetermined energy supply amount at the current location. Information indicating the cruising range from the destination (the cruising range after arrival) at each energy replenishment amount interval calculated by the arriving cruising range calculation means 179 is output to the cruising range drawing means 180 after arrival. .

  The post-arrival cruising range drawing means 180 is based on the destination information and drawing information input by the user via the input unit 11, and the post-arrival cruising range calculation means 179. The cruising range after arrival corresponding to the drawing information is drawn on the map displayed on the display unit 14. The post-arrival cruising range information drawn by the post-arrival cruising range drawing unit 180 is output to the necessary charge amount display unit 177.

Next, the operation of the energy supply information acquisition device 1 configured as described above will be described. In the following, it is assumed that the display unit 14 is a touch panel display, and the user performs input using this touch panel.
In the operation of the energy supply information acquisition apparatus 1, as shown in FIG. 2, first, the control unit 17 calculates a range that can be navigated from the current location with the current remaining energy (step ST21). That is, the current cruising range calculation means 172 calculates the cruising range with the current energy remaining amount of the vehicle based on the vehicle information acquired by the vehicle information acquisition unit 12. At this time, information indicating the road gradient included in the map DB 161 of the storage unit 16, traffic congestion information that can be acquired from the communication unit 15, information indicating the presence or absence of use of the air conditioner input to the user input via the input unit 11, and the like. You may consider it. Also, the season, the presence or absence of rain, the time zone, etc. may be taken into consideration. Furthermore, the user's driving pattern may be set in advance, or a learning function may be provided to learn the driving pattern and reflected in the calculation of the cruising range (hereinafter, when calculating the cruising range, these information may be used). Including the possibility of using).

Next, the mode selection means 173 of the control unit 17 determines whether the current location mode is selected instead of the destination mode via the input unit 11 (step ST22).
In step ST22, when the control unit 17 determines that the current location mode is selected by the user, the control unit 17 calculates a cruising range corresponding to the charge amount (step ST23). That is, the cruising range calculation means 174 after charging is based on the vehicle information acquired by the vehicle information acquisition unit 12, and the cruising range after energy supply is changed from the current remaining energy amount to the full amount of energy. Calculated for each predetermined amount of energy supply.

Next, the control unit 17 draws a cruising range from the current location with the current energy remaining amount on the map (step ST24). In other words, the current reachable range drawing means 175 is displayed on the display unit 14 based on the current location information acquired by the current location information acquisition unit 13 and the current reachable range calculated by the current reachable range calculation unit 172. Draw the current cruising range of the vehicle on the map.
As a result, as shown in FIG. 3A, a range that can be navigated from the current location 301 with the current remaining energy amount (current reachable range 302) is drawn on the map displayed on the display unit 14.

  Further, when drawing the current cruising range in step ST24, as shown in FIG. 3C, the maximum range (maximum cruising range 304) that the vehicle can continue from the current location after charging is also drawn simultaneously. May be. In this case, the current reachable range drawing means 175 is calculated by the current location information acquired by the current location information acquisition unit 13 and the post-charge reachable range calculation means 174 in addition to the above-described drawing process of the current reachable range of the vehicle. The maximum cruising range after charging of the vehicle is drawn on the map displayed on the display unit 14 based on the cruising range with the full amount of energy (full charge). In this way, by drawing the maximum cruising range after charging on the map, it is possible to know whether the moving range desired by the user is a range that can be driven by one charge before the user performs input. .

Next, the control unit 17 determines whether there is an input from the user via the input unit 11 (step ST25). Here, when the user inputs drawing information, as shown in FIG. 3, the user touches the current navigable range 302 displayed on the display unit 14 and slides it to a desired position. Do. On the other hand, when ending the process, for example, an end instruction is given by touching an end button (not shown).
In this step ST25, when the control unit 17 determines that there is no input by the user, the sequence returns to step ST25 again and enters a standby state.

  On the other hand, when determining in step ST25 that there is an input by the user, the control unit 17 analyzes the information input by the user (step ST26). That is, the input information analysis unit 171 analyzes information input via the input unit 11. Here, for example, when information indicating coordinate values is input as drawing information, the input information analysis unit 171 converts this information into coordinate values on a map.

Next, the control unit 17 determines whether the input information is not an end instruction but drawing information (step ST27).
In step ST27, when the control unit 17 determines that the input information is an end instruction, the sequence ends.

On the other hand, if the control unit 17 determines in step ST27 that the input information is drawing information, it draws a cruising range after charging from the current location according to the drawing information (step ST28). In other words, the post-charge cruising range drawing means 176 is provided via the current location information acquired by the current location information acquisition unit 13, the post-charge cruising range calculated by the post-charge cruising range calculation unit 174, and the input unit 11. Based on the drawing information acquired by the above, a post-charge cruising range corresponding to the drawing information is drawn on the map displayed on the display unit 14.
Here, as shown in FIG. 3B, when the user touches the current cruising range 302 displayed on the display unit 14 and slides to a desired position as it is, charging corresponding to each slide position is performed. The subsequent cruising range 303a, 303b is drawn continuously (for each predetermined amount of energy supply).

Subsequently, the control part 17 acquires and displays the required charge amount according to the drawn cruising range (steps ST29 and ST30). That is, the required charge amount display means 177 acquires the amount of energy replenishment necessary for traveling from the current location to the post-charge cruising range drawn by the post-charge cruising range drawing means 176 and displays it on the display unit 14.
Thereby, as shown in FIG.3 (b), the energy replenishment amount required for drive | working from the present location 301 to the cruising range 303b after a charge is displayed on the map currently displayed on the display part 14. FIG.
Thereafter, the sequence returns to step ST25.

On the other hand, in step ST22, when the control unit 17 determines that the destination mode is selected instead of the current location mode, the sequence proceeds to step ST31. When the destination mode is selected, the control unit 17 causes the user to input destination information via the input unit 11.
Here, when the destination information is input, the user inputs the destination information by touching a desired position on the map displayed on the display unit 14 as shown in FIG.

  Next, the control unit 17 calculates the amount of energy necessary to arrive at the destination input by the user (step ST31). In other words, the destination arrival availability determination unit 178 includes destination information input by the user via the input unit 11, vehicle information acquired by the vehicle information acquisition unit 12, current location information acquired by the current location information acquisition unit 13, and Based on map DB161 etc. which are memorize | stored in the memory | storage part 16, energy amount required to drive | work from a present location to the destination is calculated.

  Next, the control unit 17 determines whether it is possible to reach the destination from the current location with the full amount of energy (step ST32). In other words, the destination arrival determination unit 178 calculates the difference between the amount of energy required to travel from the current location to the destination and the full amount of energy, so that the full amount of energy can be used to move from the current location to the destination. Determine if it can be reached.

  In step ST32, when the control unit 17 determines that it is impossible to reach the destination from the current location with the full amount of energy, the sequence returns to step ST22. At this time, the user is made to recognize whether the destination can be reached by the color of the star indicating the destination 401 shown in FIG.

  On the other hand, in step ST32, when the control unit 17 determines that the vehicle can reach the destination from the current location with the full amount of energy, the predetermined energy supply at the current location is performed for the range that can be reached after the arrival at the destination. Calculation is performed for each quantity interval (step ST33). In other words, the cruising range calculation means 179 after arrival includes the destination information input by the user via the input unit 11, the vehicle information acquired by the vehicle information acquisition unit 12, and the current location information acquired by the current location information acquisition unit 13. And based on map DB161 etc. which are memorize | stored in the memory | storage part 16, the cruising range from a destination is calculated for every predetermined energy supply amount in a present location.

Next, the control unit 17 draws a cruising range from the current location with the current energy remaining amount on the map (step ST34).
As a result, as shown in FIG. 4A, the range that can be navigated from the current location 301 with the current remaining energy (the current cruising range 302) is drawn on the map displayed on the display unit 14.

  Further, when drawing the current cruising range in step ST34, as shown in FIG. 4C, the maximum range (maximum cruising range 403) that the vehicle can travel from the destination after charging is drawn simultaneously. It may be. In this case, the current reachable range drawing means 175, in addition to the above-described drawing processing of the current reachable range of the vehicle, destination information input by the user via the input unit 11 and the reachable reachable range calculation means 179. The maximum cruising range after charging the vehicle is drawn on the map displayed on the display unit 14 based on the cruising range with the full amount of energy (full charge) calculated by the above. In this way, by drawing the maximum cruising range after charging on the map, it is possible to know whether the moving range desired by the user is a range that can be driven by one charge before the user performs input. .

Next, the control unit 17 determines whether there is an input from the user via the input unit 11 (step ST35). Here, when the user inputs drawing information, for example, as shown in FIG. 4, the user touches a destination 401 on the map displayed on the display unit 14 and slides it to a desired position. I do.
In step ST35, when the control unit 17 determines that there is no input by the user, the sequence returns to step ST35 again and enters a standby state.

On the other hand, when determining in step ST35 that there is an input by the user, the control unit 17 analyzes the information input by the user (step ST36).
Next, the control unit 17 determines whether the input information is drawing information instead of an end instruction (step ST37).
In step ST37, when the control unit 17 determines that the input information is an end instruction, the sequence ends.

On the other hand, when determining in step ST37 that the input information is drawing information, the control unit 17 draws a cruising range after arrival from the destination according to the drawing information (step ST38). That is, the post-arrival cruising range drawing means 180 is based on the destination information and drawing information input by the user via the input unit 11 and the post-arrival cruising range calculation means 179 acquired by the post-arrival cruising range. Then, the cruising range after arrival corresponding to the drawing information is drawn on the map displayed on the display unit 14.
Here, for example, as shown in FIG. 4B, when the user touches the destination 401 on the map displayed on the display unit 14 and slides to a desired position as it is, it corresponds to each slide position. The cruising range 402a, 402b after arrival is drawn continuously (every energy replenishment amount at the current location 301).

Subsequently, the control part 17 acquires the required charge amount according to the drawn cruising range and displays it on the display part 14 (steps ST39 and 40).
As a result, as shown in FIG. 4B, the amount of energy supply required at the current location 301 for traveling from the destination 401 to the cruising range 402b after arrival is displayed on the map displayed on the display unit 14. Is done.
Thereafter, the sequence returns to step ST35.

  As described above, according to the first embodiment, the cruising range from a predetermined position (current location or destination) is calculated stepwise according to the amount of energy supply at the current location, and the touch panel or the like is used. Since the cruising range from the predetermined position is specified by the user, the energy supply amount required for traveling to the cruising range is calculated and displayed, so the user can travel from the predetermined position to the desired cruising range. It is possible to easily obtain the amount of energy replenishment necessary to do. In addition, the user can easily know whether the destination can be reached with the current remaining energy amount or full energy amount. In addition, the amount of energy replenishment necessary for moving within a predetermined range after arrival at the destination can be easily acquired, and the amount of energy replenishment after considering the remaining power after arrival at the destination can be easily acquired.

  In the first embodiment, as shown in FIGS. 3 and 4, the cruising range is input by a touch / slide input operation using a touch panel display. However, the present invention is not limited to this, for example, using a button. All means capable of inputting a signal, such as a method for inputting a cruising range and a method for inputting a cruising range using voice or biological information, can be applied as means for inputting a cruising range.

Embodiment 5 FIG.
In the first to fourth embodiments, information about the amount of energy replenishment required to travel to the cruising range is presented by inputting the cruising range from a predetermined position by the touch / slide input operation by the user. . On the other hand, in the fifth embodiment, when the desired cruising range is input by the handwriting input operation by the user, the cruising range that best matches the trajectory is calculated and displayed, and information on the necessary energy supply amount It shows about what presents.
The control unit 17d in the fifth embodiment shown in FIG. 8 is different from the control unit 17 in the first embodiment shown in FIG. 1 in the supply information acquisition method selection unit 190, the maximum cruising range drawing unit 191, the trajectory drawing unit 192, and the cruising range. A range matching unit 193 and a matching range drawing unit 194 are added. Further, the necessary charge amount display means 177 is changed to the necessary charge amount display means 177d. In addition, in the energy supply information acquisition device 1d according to the fifth embodiment shown in FIG. 8, the configuration not described in the following text is the same as the configuration of the first embodiment shown in FIG.

  The replenishment information acquisition method selection unit 190 allows the user to select a touch / slide input mode or a handwriting input mode via the input unit 11. Here, the touch / slide input mode is a mode for acquiring information related to the amount of energy supply by performing the touch / slide input operation described in the first to fifth embodiments. The handwriting input mode is a mode for acquiring information related to the amount of energy supply by performing a handwriting input operation.

The maximum cruising range drawing means 191 is based on the current location information acquired by the current location information acquisition unit 13 and the cruising range with the full amount of energy calculated by the post-charge cruising range calculation unit 174. The maximum cruising range is drawn on the map displayed at 14.
The trajectory drawing unit 192 draws the trajectory input by the user via the input unit 11 on the map displayed on the display unit 14.

  The cruising range matching unit 193 is configured to input a trajectory (desired cruising range) based on the trajectory input by the user via the input unit 11 and each post-charge cruising range acquired by the post-charge cruising range calculation unit 174. Range) that most closely matches (range). The matching process by the cruising range matching unit 193 will be described later. Information indicating the matching cruising range calculated by the cruising range matching unit 193 is output to the matching range drawing unit 194.

  The matching range drawing unit 194 performs matching cruising on the map displayed on the display unit 14 based on the current location information acquired by the current location information acquisition unit 13 and the matching cruising range calculated by the cruising range matching unit 193. The range is drawn.

  In addition to the function in the first embodiment, the required charge amount display unit 177d is used to travel from the current location to this matching cruising range when the matching range cruising range is drawn by the matching range drawing unit 194. Acquire and display the required amount of energy supply.

Next, an example of matching processing by the cruising range matching means 193 will be described with reference to FIG.
FIG. 9 shows the current location 901 of the vehicle and three candidates for the range that can be drawn (ranges A to C) (the ranges A to C are not actually displayed). This cruising range candidate is equivalent to the cruising range calculated by the cruising range calculation means 174 after charging.
In this state, the cruising range matching unit 193 calculates a cruising range close to the trajectory 902 by the following process when the trajectory 902 is input by the user as shown in FIG.

First, as shown in FIG. 9, lines are drawn at a predetermined interval in a radial pattern from the current location 901 so as to intersect with the input line 902 input by handwriting by the user. In the example of FIG. 1, OC. 2 is drawn.
Next, the nearest cruising range candidate (inner range candidate) on the current location 901 side from the intersection (I.1, I.2) of the input line 902 and the line segment, and the nearest range candidate (outer range candidate) on the opposite side ). In the example of FIG. 9, the range A is 0 point, the range B is 2 points (inner range candidate), and the range C is 2 points (nearest outer range candidate).
Next, on the inside and outside of the input line 902, the cruising range having the highest score is set as a matching candidate. In the example of FIG. 9, range B and range C remain as matching candidates.

  Next, the intersection between the matching candidate and the line segment and the distance between the intersection between the input line 902 and the line segment are obtained, and the shorter distance is calculated as the matching cruising range. In the example of FIG. 1-I. 1 and B. 2-I. Is the sum of the distances between the two, and the total distance of the range C is C.I. 1-I. 1 distance and C.I. 2-I. It is the sum of the distance between the two. In this case, the total distance of the range C is smaller than the total distance of the range B, and the range C is calculated as the matching cruising range.

Next, the operation of the energy supply information acquisition device 1d configured as described above will be described. In the following, the operation when the user selects the current location mode will be described, but the same operation is performed when the destination mode is selected.
In the operation of the energy supply information acquisition device 1d, as shown in FIG. 10, first, the control unit 17d calculates a range that can be navigated from the current location with the current remaining energy (step ST101). Next, the control unit 17d calculates a cruising range according to the charge amount (step ST102). Next, the control unit 17d draws the cruising range from the current location with the current energy remaining amount on the map (step ST103).

Next, the control unit 17d determines whether the user selects the handwriting input mode instead of the touch / slide input mode via the input unit 11 (step ST104). That is, the replenishment information acquisition method selection unit 190 allows the user to select either the touch / slide input mode or the handwriting input mode via the input unit 11.
In step ST104, when it is determined that the touch / slide input mode is selected by the user, the control unit 17d shifts to the touch / slide input mode (step ST105). That is, the operation proceeds to the operation after step ST25 in FIG.

On the other hand, when determining in step ST104 that the handwriting input mode has been selected by the user, the control unit 17d draws the maximum cruising range from the current location on the map (step ST106). That is, the maximum cruising range drawing unit 191 is based on the current location information acquired by the current location information acquisition unit 13 and the cruising range with the full amount of energy calculated by the post-charge cruising range calculation unit 174. The maximum cruising range is drawn on the map displayed on the display unit 14.
Accordingly, as shown in FIG. 11A, the maximum cruising range 1101 is drawn on the map on which the current location 301 of the vehicle and the current cruising range 302 are drawn.

Next, the control unit 17d determines whether there is an input by the user via the input unit 11 (step ST107). Here, when the user inputs the trajectory of the desired cruising range by handwriting, for example, as shown in FIG. 11A, the user touches a desired position on the map displayed on the display unit 14. Tracing is input by tracing.
In step ST107, when the control unit 17d determines that there is no input by the user, the sequence returns to step ST107 again and enters a standby state.
On the other hand, when determining in step ST107 that there is an input by the user, the control unit 17d analyzes the information input by the user (step ST108). That is, the input information analysis unit 171 analyzes information input via the input unit 11. Here, when information indicating each coordinate value is input as, for example, trajectory information, the input information analysis unit 171 converts this information into a coordinate value on the map.

Next, the control unit 17d determines whether the input information is trajectory information instead of an end instruction (step ST109).
In step ST109, when the control unit 17d determines that the input information is an end instruction, the sequence ends.

On the other hand, when determining in step ST109 that the input information is the trajectory information, the control unit 17d draws the trajectory on the map (step ST110). That is, the trajectory drawing unit 192 draws the trajectory input by the user via the input unit 11 on the map displayed on the display unit 14.
Thereby, as shown in FIG. 11A, a trajectory 1102 traced by the user on the map is drawn.

  Next, the control unit 17d calculates a cruising range that best matches the input trajectory (step ST111). In other words, the cruising range matching unit 193 determines the most input trajectory based on the trajectory input by the user via the input unit 11 and each post-charge cruising range obtained by the post-charge cruising range calculation unit 174. The range that can be matched is calculated.

Next, the control unit 17d draws the calculated matching cruising range (step ST112). That is, the matching range drawing means 194 is displayed on the map displayed on the display unit 14 based on the current location information acquired by the current location information acquisition unit 13 and the matching cruising range calculated by the cruising range matching unit 193. Draw the matching range.
As a result, as shown in FIG. 11, a cruising range 1103 that matches the trajectory 1102 input by the user by hand is drawn.

Next, the control unit 17d acquires and displays the necessary charge amount according to the drawn cruising range (step ST113). That is, the required charge amount display unit 177d acquires the amount of energy replenishment necessary for traveling from the current location to the post-charge cruising range drawn by the matching range drawing unit 194 and displays it on the display unit 14.
As a result, as shown in FIG. 11 (b), the energy supply amount necessary for traveling from the current location 301 to the matching cruising range 1103 is displayed on the map displayed on the display unit 14.
Thereafter, the sequence returns to step ST107.

  As described above, according to the fifth embodiment, when the desired cruising range is input by handwriting by the user, the cruising range that best matches the trajectory is calculated and displayed, and the necessary energy supply amount is displayed. Since it comprised so, compared with Embodiment 1-4, operation from the input of the desired cruising range to acquisition of supplement information can be performed still more easily.

Embodiment 6 FIG.
In the sixth embodiment, communication with an energy replenisher having a communication function is performed to control the energy replenisher.

Means 198 and energy replenisher control means 199 are added. In the energy supply information acquiring apparatus 1e according to the sixth embodiment shown in FIG. 12, the configuration not described in the following text is the same as the configuration of the first embodiment shown in FIG.

The energy supply machine search means 195 searches for an energy supply machine capable of communication via the communication unit 15 based on an instruction input by the user via the input unit 11.
The search result display unit 196 displays information on the display unit 14 when an energy supply unit that can communicate with the energy supply unit search unit 195 is found.
When the energy replenisher displayed by the search result display unit 196 is selected by the user via the input unit 11, the communication connection unit 197 establishes a communication connection with the communication unit of the selected energy replenisher. It is something that is done through.

The replenishable status confirmation unit 198 confirms whether or not energy replenishment from the energy replenisher to the vehicle can be started via one or both of the vehicle information acquisition unit 12 and the communication unit 15. .
When the communication connection unit 197 establishes a communication connection between the vehicle and the energy supply unit and the replenishment status confirmation unit 198 confirms that the energy replenishment start state can be started, the energy replenisher control unit 199 receives the input unit. 11, based on an instruction input by the user via 11, control of energy supply condition setting, replenishment start / end instruction, etc. for this energy replenisher is performed via the communication unit 15.

The operation of the energy supply information acquisition device 1e configured as described above will be described. In the following, the operation when the user selects the current location mode will be described, but the same operation is performed when the destination mode is selected.
In the operation of the energy supply information acquisition device 1e, as shown in FIG. 13, first, it is assumed that the control unit 17e has pressed a button for starting a search for an energy supply machine that can be communicated by the user via the input unit 11. If it is determined (step ST131 'YES'), the energy supply machine search means 195 searches through the communication unit 15 whether there is an energy supply machine that can communicate with the surroundings (step ST132).

  Next, when the energy supply machine search means 195 finds a communicable energy supply machine (step ST133 'YES'), the search result display means 196 displays the search result on the display unit 14 (step ST134). In addition, when the energy supplement machine search means 195 cannot find the communicable energy supplement machine, it displays that on the display part 14, and complete | finishes a sequence.

  Next, when the control unit 17e determines that the communicable energy supply device displayed on the display unit 14 has been selected by the user via the input unit 11 (step ST135 'YES'), the communication connection unit 197 performs communication. Communication connection with the selected energy supply machine is performed via the unit 15 (step ST136).

Next, the replenishment status confirmation unit 198 confirms whether or not energy replenishment from the energy replenisher to the vehicle can be started via one or both of the vehicle information acquisition unit 12 and the communication unit 15 (step ST137). ). Here, the replenishment status confirmation means 198 confirms whether or not energy replenishment can be started, for example, by confirming whether a replenishment plug of the energy replenisher is connected to the vehicle.
In this step ST137, if the replenishment status confirmation means 198 determines that the energy supply from the energy replenisher to the vehicle can be started, it proceeds to the subsequent steps and determines that the energy supply cannot be started. If so, it will be in a standby state. Further, when it is confirmed that energy supply from the energy replenisher to the vehicle can be started via one or both of the vehicle information acquisition unit 12 and the communication unit 15 during the standby, the following steps are performed. Proceed to
The subsequent processes of steps ST138 to 146 are the same as the operations of steps ST21 to 30 shown in FIG.

Note that when drawing the current cruising range in step ST140, the maximum range in which the vehicle can continue from the current location after charging may be drawn at the same time. In this case, the current reachable range drawing means 175 is calculated by the current location information acquired by the current location information acquisition unit 13 and the post-charge reachable range calculation means 174 in addition to the above-described drawing process of the current reachable range of the vehicle. The maximum cruising range after charging of the vehicle is drawn on the map displayed on the display unit 14 based on the cruising range with the full amount of energy (full charge).
In this way, by drawing the maximum cruising range after charging on the map, it is possible to know whether the moving range desired by the user is a range that can be driven by one charge before the user performs input. .

Next, the control unit 17e determines whether the determination button is pressed instead of the change button by the user via the input unit 11 (step ST147). Here, as shown in FIG. 14A, the display unit 14 displaying the cruising range after charging has a determination button for determining the cruising range after charging as a desired cruising range, A change button (return) for resetting the cruising range is displayed, and the user touches any button.
In step ST147, when the control unit 17e determines that the change button has been pressed by the user, the sequence returns to step ST141.

  On the other hand, in step ST147, when it is determined that the determination button has been pressed by the user, the control unit 17e determines whether an energy supply start command is input by the user via the input unit 11 (step ST148). Here, as shown in FIG. 14B, a button (yes, no) indicating whether or not to start energy supply is displayed on the display unit 14, and the user touches any button.

  In step ST148, when the control unit 17e determines that an energy supply start command has been input by the user, the energy supply machine control unit 199 determines that the energy supply command (setting of supply conditions, supply start / end commands, etc.) ) Is transmitted to the energy replenisher via the communication unit 15 and controlled (step ST149).

Next, the control unit 17e determines whether an additional command has been input by the user via the input unit 11 (step ST150).
In step ST150, when the control unit 17e determines that an additional command has been input, the sequence returns to step ST148.
On the other hand, if the control unit 17e determines in step ST148 that an end instruction has been input, or if in step ST150 the control unit 17e determines that no additional command has been input, the sequence ends. .

  As described above, according to the sixth embodiment, since the communication is performed with the energy replenisher having the communication function, and the energy replenishment machine is configured to set the energy replenishment and start / end instructions, etc. After the user acquires information on the required amount of energy supply by the energy supply information acquisition device 1e, the user can set the conditions for energy supply and start and end the supply of the energy supply without having to bother to go to the location of the energy supply machine. This can further improve convenience.
