<A. Embodiment>
<A-1. Configuration>
The charging guide device of the present invention performs charging guidance at an appropriate timing for a moving body such as a vehicle that runs using a storage battery as a drive source. In the present embodiment, the charging guide device will be described as an in-vehicle navigation device, but it may be mounted on a mobile body other than the vehicle.

FIG. 1 is an external configuration diagram of the navigation device 1 of the present invention. Hereinafter, the input / output information of the navigation device 1 will be described with reference to FIG.

Navigation device 1 acquires a GPS (Global Positioning System) signal from a GPS satellite, and calculates the current position of the vehicle on which navigation device 1 is mounted based on the GPS signal. In addition, the navigation device 1 acquires remaining power amount (storage battery amount) information of the storage battery 4 that is a drive source of the vehicle 3. In addition, various user operations are input to the navigation device 1 through an operation input unit such as a touch panel or a switch group provided on the housing of the device. Although details will be described later, setting of a non-measurement range, setting of a charging guidance method, and the like are input to the navigation device 1 by a user operation.

Navigation device 1 displays a non-measurement range based on the above user operation, the current position of the vehicle, and the current amount of storage battery, and displays a charging guide. Details of these operations will be described later.

Next, the internal configuration of the navigation device 1 will be described with reference to FIG. FIG. 2 is an internal configuration diagram of the navigation device 1.

The navigation device 1 includes an operation input unit 14 that receives user operations, a display unit 19 that displays various types of information, and a position information acquisition unit 20 that receives a GPS signal and acquires the current position of the vehicle. The operation input unit 14 is, for example, a mechanical switch or an electronic switch. When the display unit 19 is configured by a liquid crystal display, the operation input unit 14 is configured integrally with the display unit 19 as a touch panel.

The navigation device 1 includes a storage battery amount acquisition unit 11, a charging guidance method setting unit 12, a non-measurement range setting unit 13, and a travel history recording unit 15 as processing units that perform various processes, and further includes data associated with these processes. Is stored. The data storage unit 16 stores, for each type of information to be stored, a storage battery amount information DB (database) 16a, a charging guidance method information DB (database) 16b, a non-measurement range information DB (database) 16c, and a travel history information DB (database). 16d.

The storage battery amount acquisition unit 11 acquires the storage battery amount of the storage battery 4 that is the drive source of the vehicle 3 on which the navigation device 1 is mounted as storage battery amount information, and stores it in the storage battery amount information DB 16a.

The charging guidance method setting unit 12 sets the charging guidance method according to the user operation input from the operation input unit 14, and stores the charging guidance method information in the charging guidance method information DB 16b. As the charging guidance method, for example, telop display, icon display, and the combination of the former two are conceivable.

The non-measurement range setting unit 13 sets a non-measurement range indicating the range and display form of the non-measurement range in accordance with a user operation input from the operation input unit 14, and stores the non-measurement range information in the non-measurement range information DB 16c. . The non-measurement range is a fixed range including the reference point, and is a range not to be recorded as a travel history for guidance. The reference point is a point where there is a parking space, such as a user's home or office, where charging is possible. When the user's home is set as the reference point, the non-measurement range is set to a range around the home including places frequently visited by the user in daily life, such as a nearby supermarket or convenience store.

The travel history recording unit 15 compares the current position of the vehicle 3 with the non-measurement range, and records the travel history of the vehicle 3 when the current position is outside the non-measurement range. Here, the travel history includes at least one of the travel distance of the vehicle and the power consumption.

Further, the navigation device 1 includes a guidance necessity determination unit 17 that determines whether or not to perform charging guidance, and a charging guidance unit 18 that performs charging guidance for the user based on the above determination. The charging guide unit 18 performs charging guidance by performing guidance display on the display unit 19 and also performs charging guidance by sound output from a speaker (not shown).

<A-2. Basic operation>
FIG. 3 is a flowchart showing an outline of the operation of the navigation device 1. The processing of the navigation device 1 includes a storage battery amount acquisition process (step S1), a charging guidance method setting process (step S2), a non-measurement range setting process (step S3), and a travel history recording process (step S5). . These processes are performed in parallel at any time.

In the storage battery amount acquisition process (step S1), the storage battery amount acquisition unit 11 acquires storage battery amount information from the storage battery 4, and stores it in the storage battery amount information DB 16a.

In the charging guidance method setting process (step S2), upon receiving a user operation, the charging guidance method setting unit 12 stores the charging guidance method information in the charging guidance method information DB 16b. The charging guidance method information is information indicating a charging guidance method such as telop display or icon display.

In the non-measurement range setting process (step S3), in response to a user operation, the non-measurement range setting unit 13 stores the non-measurement range information in the non-measurement range information DB 16c. The non-measurement range information is information indicating the range and display form of the non-measurement range.

When a trigger for executing the travel history recording process (step S5) occurs, the travel history recording unit 15 determines whether or not the non-measurement range has been set (step S4). If the non-measurement range setting process is executed and the non-measurement range information DB 16c is stored in the non-measurement range information DB 16c, “Yes” is determined in step S4, and the travel history recording unit 15 executes the travel history recording process (step S5). If the out-of-measurement range has not yet been set, No is made in step S4, and execution of the travel history recording process (step S5) is awaited until it is set.

It should be noted that the execution triggers of the processes in steps S1, 2, 3, and 5 described above are different from each other, and are not necessarily performed in parallel at the same timing.

After each process of steps S1, 2, 3, and 5 is performed at least once, the guidance necessity determination unit 17 performs a guidance necessity determination process at a predetermined timing (step S6). If it is determined in step S6 that charging guidance is necessary, the charging guidance unit 18 performs a charging guidance process (step S7).

<A-3. Storage battery amount acquisition processing>
FIG. 4 is a flowchart showing a storage battery amount acquisition process (step S1 in FIG. 3) performed by the storage battery amount acquisition unit 11. Hereinafter, the storage battery amount acquisition process will be described with reference to FIG. First, the storage battery amount acquisition unit 11 acquires storage battery amount information from the storage battery 4 (step S11). The storage battery amount acquisition unit 11 compares the storage battery amount information acquired this time with the storage battery amount information acquired last time, and determines whether or not the storage battery amount has changed (step S12). Specifically, the amount of change in the storage battery amount is compared with a predetermined threshold, and it is determined that the amount of change has changed when the amount of change is equal to or greater than the threshold.

If the storage battery amount has not changed (No in step S12), the process is terminated. When it has changed (Yes in Step S12), the storage battery amount information acquired this time is stored in the storage battery amount information DB 16a (Step S13), and the process is terminated. When the previous storage battery amount information is already stored in the storage battery amount information DB 16a, the storage battery amount information DB 16a is updated with the storage battery amount information acquired this time.

Since the above operation is repeatedly performed, for example, at a constant cycle, the latest storage battery amount information is always recorded in the storage battery amount information DB 16a.

<A-4. Charging guidance method setting process>
FIG. 5 is a flowchart showing the charging guidance method setting process (step S2 in FIG. 3) performed by the charging guidance method setting unit 12. Hereinafter, the charging guidance method setting process will be described with reference to FIG.

When the user selects the charging guidance method from the operation input unit 14 (step S21), the charging guidance method setting unit 12 stores the charging guidance method information indicating the charging guidance method in the charging guidance method information DB 16b (step S22). If the charging guidance method information is already stored, the charging guidance method information DB 16b is updated with the new charging guidance method information. The charging guidance method includes, for example, icon display, telop display, or a combination thereof.

The charging guidance method setting process is completed when the charging guidance method information is stored in the charging guidance method information DB 16b. However, the setting content may be displayed on the display unit 19 to notify the user (step S23). ). In addition to the display, this notification may be output by sound output from a speaker (not shown).

Since the charging guide method setting process is performed every time the user selects the charging guide method from the operation input unit 14, the charging guide method information DB 16b always includes the charging guide method information indicating the latest charging guide method selected by the user. Stored.

<A-5. Outside measurement range setting processing>
FIG. 6 is a flowchart showing the non-measurement range setting process (step S3 in FIG. 3) performed by the non-measurement range setting unit 13. Hereinafter, the non-measurement range setting process will be described with reference to FIG. This process is triggered by an operation on the operation input unit 14.

First, the user sets a reference point from the operation input unit 14 (step S31). As a reference point setting method, for example, an arbitrary point on the map displayed on the display unit 19 may be designated, an address may be input, or a point registered in advance may be selected. May be.

When the reference point is set, a map centered on the reference point is displayed on the display unit 19, and the user sets the range of the non-measurement range while viewing the map (step S32). Subsequently, the transmissive display color is set on the display unit 19 in the non-measurement range (step S33) and the transmittance is set (step S34). The display unit 19 displays a non-measurement range according to the above setting. Thereafter, the non-measurement range information indicating the set non-measurement range, the transmissive display color, and the transmittance is stored in the non-measurement range information DB 16c (step S35), and the process ends.

FIG. 7 is a flowchart showing in detail the range setting process (step S32 in FIG. 6) of the non-measurement range. The display unit 19 displays a screen for selecting a method for setting a non-measurement range, and the user selects either “default” or “arbitrary” as the shape type. The non-measurement range setting unit 13 determines whether “default” or “arbitrary” is selected (step S321).

When “default” is selected, a non-measurement range is set using a shape that has already been registered, such as a circle, a triangle, or a rectangle, or a block shape that can be acquired from map data (step S322). Here, the block indicates an area surrounded by a road. FIG. 9 shows an example in which the non-measurement range is set using the block shape. Here, the reference point is set in the facility, and the block including the facility is set as a non-measurement range.

When “arbitrary” is selected, the user subsequently specifies the position of the vertex on the screen, and the area connecting the vertex is set as the non-measurement range (step S323).

For example, when a navigation function such as route guidance is executed, the non-measurement range set in this way is displayed separately from others in a transparent color on the map around the vehicle position.

<A-6. Travel history recording process>
FIG. 8 is a flowchart showing a travel history recording process (step S5 in FIG. 3) performed by the travel history recording unit 15. Hereinafter, the travel history recording process will be described with reference to FIG. This process is repeatedly performed at a constant cycle, for example.

First, the travel history recording unit 15 acquires the vehicle position information from the position information acquisition unit 20 (step S51). Then, the vehicle position information acquired this time is compared with the vehicle position information acquired last time, and it is determined whether or not the vehicle position has changed (step S52). Specifically, the amount of change in the vehicle position is compared with a predetermined threshold, and it is determined that the vehicle position has changed when the amount of change is equal to or greater than the threshold. If it is determined that the vehicle position has not changed (No in step S52), the process returns to step S51 to acquire the vehicle position information again.

If it is determined that the vehicle position has changed (Yes in step S52), the non-measurement range information is acquired from the non-measurement range information DB 16c (step S53). Then, the vehicle position information acquired in step S51 is compared with the non-measurement range information acquired in step S53, and it is determined whether or not the vehicle position is outside the measurement range (step S54). If the vehicle position is within the measurement outside range (No in step S54), the process is terminated.

If the vehicle position is out of the measurement outside range (Yes in step S54), the recording of the travel history is started (step S55). Here, the travel history includes at least either the travel distance of the vehicle 3 or the power consumption. After recording the travel history for a certain period, the vehicle position information is acquired again from the position information acquisition unit 20 (step S56). Then, the own vehicle position information is compared with the measurement range information acquired in step S53, and it is determined whether or not the own vehicle position is within the non-measurement range (step S57). If the vehicle position is outside the measurement outside range, the process returns to step S55 to record the travel history, and if the vehicle position is within the measurement outside range, the process proceeds to step S58. That is, while the vehicle is traveling outside the measurement range, the travel history is continuously recorded.

In step S58, an average travel history is calculated from the current travel history and the past travel history recorded in step S55. That is, the past travel history is acquired from the travel history information DB 16d, and the average value of the past travel history and the travel history recorded in step S55 is obtained. For example, it is assumed that the travel distance for the past four travels is recorded in the travel history information DB 16d, the average travel distance per time is 50 km, and the current travel distance is 100 km. In this case, the new average travel distance is calculated as (50 × 4 + 100) / 4 = 75 km (step S58), and this is stored in the travel history information DB 16d as a new average travel history (step S59). Here, the travel distance per time is a distance traveled from the time when the host vehicle goes out of the measurement outside range until it returns to the measurement outside range again. In the travel history information DB 16d, in addition to the past travel history, an average value thereof is also stored.

Also, not only the average travel history for all past travels, but also the average travel history may be obtained for each day of the week or for each time period, and the average travel history may be used properly according to the next travel day of the week or travel time period. Thereby, charging guidance can be performed with high accuracy reflecting the variation tendency of the user's travel distance depending on the day of the week or the time zone.

Further, only the average running history for the latest certain number of runs may be used, and the average value may be calculated not only by the simple average but also by using a weighted average having a higher specific gravity as the new running history. Thereby, the charge guidance according to the tendency of the more recent user can be performed.

Although the above description has been given of the case where the travel distance is recorded as the travel history, the average travel history is calculated in the same manner when the power consumption is recorded as the travel history.

8 will be described with reference to the example of FIG. In FIG. 9, a certain facility is set as a reference point, and a block surrounded by a road including the facility is set as a non-measurement range. The non-measurement range includes a facility and a plurality of parking lots provided around the facility.

When the vehicle 3 is traveling out of the measurement range, the travel history recording unit 15 records the travel history. When the vehicle 3 enters the outside-measurement range to enter the parking lot from the entrance / exit (1), the recording of the travel history is finished. Thereafter, the travel history is not recorded even if the vehicle moves between parking lots within the non-measurement range. When the vehicle goes out of the range outside the measurement in order to exit the road from the entrance (1), a new recording of the travel history is started.

<A-7. Guidance Necessity Judgment Processing>
FIG. 10 is a flowchart showing guidance necessity determination processing (step S6 in FIG. 3) performed by the guidance necessity determination unit 17. The guidance necessity determination process will be described below with reference to FIG. This process is repeatedly performed at a constant cycle, for example.

First, the guidance necessity determination unit 17 acquires the vehicle position information from the position information acquisition unit 20 (step S61). Then, the vehicle position information acquired this time is compared with the vehicle position information acquired last time, and it is determined whether or not the vehicle position has changed (step S62). Specifically, the amount of change in the vehicle position is compared with a predetermined threshold, and it is determined that the vehicle position has changed when the amount of change is equal to or greater than the threshold. If it is determined that the vehicle position has not changed (No in step S62), the process ends.

If it is determined that the vehicle position has changed (Yes in step S62), the non-measurement range information is acquired from the non-measurement range information DB 16c (step S63).

Then, the vehicle position information acquired in step S61 is compared with the non-measurement range information acquired in step S63, and it is determined whether or not the vehicle position is within the measurement outside range (step S64). If the vehicle position is out of the measurement outside range (No in step S64), the process is terminated.

If the vehicle position is within the non-measurement range (Yes in step S64), the storage battery amount information is acquired from the storage battery amount information DB 16a (step S65), and the average travel history is acquired from the travel history information DB 16d (step S66). .

Next, the next travelable distance is calculated (step S67). For example, the travelable distance is calculated by multiplying the current storage battery amount acquired in step S65 by the average power consumption of the vehicle.

Then, the next travelable distance is compared with the average travel history acquired in step S66, and it is determined whether or not the next travel is possible without charging (step S68). Here, the average travel distance per time and the travelable distance are compared. For example, if the average travel distance is equal to or greater than the travelable distance, it is determined that travel is possible, and if the average travel distance is less than the travelable distance, it is determined that travel is impossible. Alternatively, it may be determined that the vehicle can travel if the average travel distance is equal to or greater than a distance obtained by adding a predetermined margin distance to the travelable distance. That is, in this process, the average travel distance obtained from the travel history is estimated as the next travel distance, and whether or not the next travel is possible is determined. When the average travel history is the average power consumption, the average power consumption is multiplied by the average power consumption of the vehicle 3 to obtain the average travel distance, and this is compared with the travelable distance.

If it is determined in step S68 that the vehicle can be driven, the process is terminated. If it is determined that the vehicle cannot be driven, a charging guide process is performed (step S7).

<A-8. Charging guidance processing>
FIG. 11 is a flowchart showing the charging guidance process (step S7 in FIGS. 3 and 10) performed by the charging guidance unit 18. The guidance necessity determination process will be described below with reference to FIG.

First, charge guide method information is acquired from the charge guide method information DB 16b (step S71). Next, the type of charging guidance method is determined (step S72), and charging guidance is displayed on the display unit 19 according to the type. For example, telop display (step S73), icon display (step S74), and telop and icon display (step S75) are performed. Further, the charging guidance may be performed by a display method other than those listed here. Furthermore, charging guidance may be performed by voice output from a speaker (not shown).

As described above, in the navigation device 1 of the present embodiment, charging guidance is performed by estimating the next travel distance from the travel history recorded outside the outside measurement range. Since the travel history is not recorded within the out-of-measurement range, only the travel history when traveling out of the out-of-measurement range that travels frequently on a daily basis is reflected in the determination of the necessity of charging guidance. Therefore, the user can know from the charging guide whether or not charging is necessary when he goes out next time.

In the guidance necessity determination process shown in FIG. 10, if the time interval for acquiring the vehicle position information in step S71 is sufficiently small, the charging guidance process shown in FIG. It is done at the timing. Since the user receives the charging guidance before parking at the reference point, the user can charge in advance for the next run after parking at the reference point. In addition, since whether or not charging guidance is possible is determined based on the storage battery amount and the next estimated travel distance, it is possible to avoid shortening the life of the storage battery by performing unnecessary charging.

If the measurement outside range is set wide, even if the travelable distance exceeds the average travel distance when returning to the outside measurement range, the amount of storage battery decreases until reaching the reference point, It is conceivable that the travelable distance is less than the average travel distance. In such a case, even if it is determined that the charging guidance is unnecessary at the timing when the measurement returns to the out-of-measurement range, it is considered that the charging guidance is actually necessary. Therefore, in order to perform more accurate charging guidance, it may be periodically determined whether or not charging guidance is available until the vehicle arrives at the reference point or stops after entering the outside of the measurement range. . The operation in this case returns to step S71 again when step S78 in FIG. 9 is Yes, and repeats the charging guidance availability determination process.

<A-9. Effect>
The navigation device 1 (charging guidance device) according to the present embodiment includes a charging point (reference point) of a mobile body on which the charging guidance device is mounted, and sets a non-measurement range not to be recorded as a travel history for guidance. The measurement outside range setting unit 13, the position information acquisition unit 20 that acquires the position information of the current position of the moving body, and whether the current position of the moving body is within the outside measurement range are determined. The travel history recording unit 15 that records the travel history including at least one of the power consumption and the travel distance and the power amount (storage battery amount) of the storage battery 4 are acquired from the outside range to the return to the outside measurement range. When the storage battery amount acquisition unit 11 and the moving body are within the measurement outside range, whether or not to guide the necessity of charging of the storage battery 4 is determined based on the power amount of the storage battery 4 and the travel history. According to the judgment of the part 17 and the guidance necessity judgment part And a charging guide portion 18 for guiding the charge necessity of the battery 4. Since the travel history is not recorded within the out-of-measurement range, only the travel history when traveling out of the out-of-measurement range that travels frequently on a daily basis is reflected in determining whether or not charging guidance is necessary. Therefore, the user can know from the charging guide whether or not charging is necessary when he goes out next time. In addition, the user only needs to set the non-measurement range including the reference point once, and does not need to register the destination each time.

In addition, the guidance necessity determination unit 17 determines whether or not to guide the necessity of charging of the storage battery 4 when the mobile body (vehicle 3) returns to the outside of the measurement range, so that the charging guidance is performed at that timing. Since the user can know that charging is necessary before arriving at the reference point, the user can charge for the next run after arriving at the reference point.

In addition, the guidance necessity determination unit 17 determines whether or not to guide the necessity of charging of the storage battery 4 based on the electric energy of the storage battery 4 and the average value of the traveling history, so that the user's past traveling tendency can be determined. The charging guidance can be performed in consideration.

Also, the non-measurement range is set as a circle or an arbitrary polygon. In particular, when an arbitrary polygonal shape is set, the position of the vertex can be set by the user, so that it is possible to set a non-measurement range in accordance with the user's desire and actual situation.

In addition, the charging guide device 1 according to the present embodiment further includes a map display unit (display unit 19) that displays a map including a non-measurement range, and the display unit 19 displays the non-measurement range in a transparent color. The user can easily grasp the non-measurement range visually. Further, since the user can arbitrarily set the transmission color and the transmittance in the non-measurement range, it is user-friendly.

Further, since the charging guide unit 18 guides whether or not the storage battery 4 needs to be charged by image display or audio output, the user can recognize that charging guidance is necessary.

In the present invention, the embodiments can be appropriately modified or omitted within the scope of the invention.

Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
