Description

  The present invention relates to an electric vehicle battery remaining amount guidance display device that can guide the remaining amount of a battery that supplies electric power to a driving motor of an electric vehicle so that the user can easily understand it.

  In recent years, electric vehicles running on motors are becoming increasingly popular. In an electric vehicle, the motor is driven by the electric power stored in the battery provided in the vehicle, but the battery for traveling has been improved, but if it runs about 160 km in a fully charged state, it must be charged. The current situation is not.

  In addition, a battery for running an electric vehicle is not necessarily used for running, but also serves as a power source for various devices in the vehicle, such as a headlight and an air conditioner, and is extremely important. For this reason, in an electric vehicle, it is necessary to pay attention to the remaining battery level, and it is necessary to always check the remaining battery level in consideration of future driving schedules.

  Charging the battery of such an electric vehicle is often performed at a charging station similar to a gas station, but when using this electric vehicle in a general household, it is costly to use a charger connected to a household power source. In addition, it is considered to be a general usage form from the standpoints of battery remaining amount management and effective use of charging waiting time.

  When managing the battery level of an electric vehicle, it is conceivable to always connect it to a charger when using it at home, but there is spontaneous discharge even when the battery is not in use. Charging for full charging is continued little by little, which is not preferable. In addition, when the vehicle can travel about 160 km with a single charge, it is only necessary to reciprocate a place of about 10 km to 20 km when used for commuting to ordinary households or daily shopping, and it is not always necessary to charge every day.

  For this reason, it is a normal usage pattern to charge the battery when it is determined that it is better to charge the battery with a certain margin. Therefore, the user regularly checks the remaining battery level in consideration of future vehicle use schedules, and performs charging at the discretion of each person.

  Checking the battery level at that time is to turn on the power for the in-vehicle device of the vehicle and check the battery level indicator displayed on the vehicle meter. For example, 60% is displayed with respect to the full charge amount, and charging and driving at home are performed by taking into account the planned driving distance in the future based on the standard driving distance per unit power that can be driven by the current battery. Consider charging on the way.

  Such battery level management of an electric vehicle is performed when a navigation device is mounted on the vehicle. It is considered to display the remaining battery level on a navigation screen. In that case, for example, as shown in FIG. 11A, a display portion of “running battery level” is provided at one corner of the navigation map screen or the like, and the ratio of the current battery level to the full charge is set to, for example, “27”. It is conceivable to display a graph such as “%”, and to display the distance that can be traveled with the remaining battery level, for example, “43 km”.

  With such a display, a meter display of the remaining battery level that is not so conspicuous among various meters is displayed on the navigation screen, thereby making it easy to check the remaining battery level that is extremely important for an electric vehicle. However, as described above, it is difficult to grasp how much the vehicle can actually run with the current battery remaining amount only by the ratio of the remaining battery amount and the number of travelable distances. Therefore, for example, as shown in FIG. 11 (b), on the battery remaining amount confirmation screen, the range that can be traveled with the current remaining battery level, in particular, the range that can be reciprocated is displayed as the “current reciprocable range”. Is considered.

  When displaying the range that can be driven with the current battery level on the map, if the boundary line indicating the range that can be driven extends to the outside of the currently displayed map, it is related to the boundary outside the map display. A technique for displaying various information to be displayed on the screen is disclosed in Patent Document 1.

JP 2010-169423 A

  As described above, when managing the remaining battery level, which is extremely important for an electric vehicle, in the conventional technology, the ratio of the current battery level to the fully charged state, the distance that can be traveled with the current battery level, It has been proposed to show the distance on the map, and the distance that can be reciprocated with the current battery level, and to show the distance on the map. For daily use in shopping, shopping, etc., such a display cannot easily grasp how much the vehicle can actually travel during daily driving.

  In other words, in the conventional technology, when you try to go to the usual shopping from now on, you can not immediately know if the battery will run out on the way, specify the destination and check the number of round trip distances, run with the current battery level Compared to the possible distance, it is necessary to confirm whether the battery will not run out or how much room is available.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of an embodiment of an electric vehicle battery remaining amount guidance display device according to the present invention, and shows a functional block diagram in which the present invention can be implemented in various modes. In addition, in the same figure, the function part which performs each function can be said to be a means which performs each function.

  In the embodiment shown in FIG. 1, an electric vehicle traveling battery remaining amount detecting unit 1 is provided to detect the current remaining amount of the traveling battery for the electric vehicle. This is similar to the conventional fuel display for gasoline cars, etc. Electric cars have a large battery to supply power to the motor for running. Conventionally, the remaining power of the battery, that is, the remaining battery level is detected. Since it is displayed together with various meters on the front panel, the current remaining battery level can be detected and captured by capturing the detection signal.

  The electric vehicle traveling battery remaining amount display processing unit 2 performs a process for displaying the current remaining battery level captured by the electric vehicle traveling battery remaining amount detecting unit 1 as described above. The battery remaining amount display format selection unit 3 selects either the travelable number calculation display unit 4 or the travelable distance display unit 7 for the display. In the selection, when the initial setting is performed in advance, as a rule, the display is selected and displayed according to the setting. However, the display format can be switched according to the user's selection.

  In the travelable number calculation display section 4, as described later, when the travel destination selection list display section 17 selects and displays a travel destination for a specific travel destination or a specific travel route, the travel destination is displayed. Calculate how many times you can run with the current battery level. When displaying the number of round trips 5 for a specific facility in the list, when a list for selecting a specific facility is displayed on the list display unit 18 for selecting a specific facility in the list display unit 17 for selecting a destination, Assuming that you will return to that particular facility from, you will see how many times you can return.

  Further, when displaying the specific route travel count 6, when displaying a list for selecting a specific route on the specific route selection list display unit 25 of the travel destination selection list display unit 17, about those travel routes Calculate and display how many times you can run with the current battery level. Therefore, in the possible traveling number calculation display unit 4, when the list display process is performed in the specific facility selection list display unit 18 in the travel destination selection list display unit 17 as described above, the specific facility round-trip traveling number 5 is displayed. When the list display processing is performed in the specific route selection list display unit 25, the specific route traveling count 6 is displayed.

  The travelable distance display unit 7 displays the remaining battery capacity as shown in FIG. 11 which has been conventionally used or has been proposed. The distance that can be traveled on average with the remaining battery capacity is displayed. The reciprocable travel distance 9 displays the distance that can be reciprocated when traveling on average with the current remaining battery level. In that case, various displays conventionally proposed, such as a display on a map indicating a distance range that can be appropriately traveled as shown in FIG. 11, can be performed.

  In the present invention, as described above, the number of times allowed to run calculation display unit 4 is provided, and when the main power of the electric vehicle is turned on, for example, a screen as shown on the monitor 16 is displayed. In the illustrated example, in the specific facility selection list display unit 18 of the travel selection list display unit 17, when this vehicle is currently at home, “Maruki YM store” is the most frequently traveled facility, and then, In this example, “Ebilia” is displayed as a list of frequently visited facilities, and how many times the facility can be reached with the current battery level is displayed.

  Therefore, the user sees this display, and understands the remaining battery level as if he / she was able to go to the facility where he / she can go, for example, 22 times. Thus, it is possible to prevent a display that is difficult to understand with a sense, such as a conventional one-way traveling distance and a reciprocating traveling distance. However, the battery remaining amount display format selection unit 3 can select the travelable distance display unit 7 for each person's hobby or for those who are used to the conventional display.

  In the behavior pattern acquisition unit 10, the traveling history data storage unit 14 provided in the vehicle records traveling data of various items as shown in FIG. Various processes are performed by searching. Among them, the number-of-runs calculation unit 11 for each facility calculates the number of times of each run using data on the accumulated facilities. Based on the calculation result, the display order selection unit 21 of the specific facility selection list display unit 18 in the travel destination selection list display unit 17 to be described later, particularly as data for displaying a list in the specific facility round-trip traveling history number order 22. Use.

  In addition, the number-of-travels calculation unit 12 for each travel route calculates the number of times traveled for each travel route using the accumulated data on the travel route. Based on the calculation result, the display order selection 26 of the specific route selection list display unit 25 in the travel destination selection list display unit 17 is used particularly when the list is displayed in the order 27 of the travel history count.

  The upcoming running schedule detection unit 13 of the behavior pattern acquisition unit 10 detects, for example, a behavior pattern as shown in FIG. 9A from the behavior pattern data of the running history data storage unit 14 as described later. As a result, it is possible to know whether or how much charging is necessary for tomorrow or for running in the near future such as a few days later, based on a future driving schedule.

  In addition, when a vehicle power switch is turned on, a facility that is likely to be selected as a future destination can be displayed immediately, and the facility can be displayed how many times it can reciprocate with the current battery level. . As a result, it is possible to know the current remaining battery level sensuously without performing any special operation, and it is possible to immediately set a driving schedule in the future including the necessity of charging in the middle.

  The traveling history data storage unit 14 collects and records various traveling history data as shown in FIG. 9 (d) at the time of daily traveling as described above. As described above, the behavior pattern acquisition unit 10 can use data related to various behavior patterns.

  The current position acquisition unit 15 acquires the current position by GPS reception data provided in the navigation device or the like, self-contained navigation using a vehicle speed pulse and a gyro, etc. It is used for predicting a facility to be traveled, predicting a travel route, and searching for facilities around the current position and selecting a facility to travel.

  Although the monitor 16 preferably uses a display of a navigation device for map display or the like, the navigation device is not necessarily required, and for example, displays of various devices such as display on a display portion of a vehicle head unit may be used. it can. In particular, when a device that outputs the remaining battery power as described above and a portable information terminal or the like can be connected by communication means such as Bluetooth, the data is output to the portable device side to perform a predetermined display. You can also. In that case, the electric vehicle battery remaining amount guidance display apparatus of this invention will be used as a system of those apparatuses.

  In the destination selection list display unit 17, display processing is performed immediately when the main power supply of the vehicle is turned on, or when the list is displayed for selecting a destination facility, a destination display specified by the user is included. Various lists are displayed. It includes a specific facility selection list display unit 18 for selecting a specific facility, and a specific route selection list display unit 25 for selecting a specific travel route.

  The specific facility selection list display unit 18 displays a list for selecting a specific facility as a destination, and the list display unit for selection in all genres 19 includes, for example, a main power source of the vehicle. Is turned on, the facilities of all genres that have traveled from the current location are retrieved from the facility data stored in the travel history data storage unit 14 and displayed in various orders such as the order of the number of times of travel.

  Further, in the list display section for selection by genre 20, selection by genre such as selecting “market” on the genre selection screen in the nearby facility search screen display as shown in FIG. 7A, for example. The list display as shown in FIG. In the example shown in the figure, for each facility, an example is shown in which the corresponding position of each facility on the map screen is marked and the list display portion and the corresponding display are performed.

  The display order selection unit 21 selects the order in which the list display is to be displayed, both in the list display for all-genre selection 19 and in the list display for genre-specific selection 20. When the specific facility traveling history order 22 is selected, the data of the traveling history data storage unit 14 is used as described above, and the specific facilities are displayed in descending order of the number of traveling so far.

  On the other hand, when the display order of the specific facility round trip possible number order 23 is selected, the display is performed in order of the number of times that the specific facility can travel with the current battery remaining amount. It becomes almost equal to the order of distance. However, in the present invention, the distance traveled by the vehicle can be displayed in the order in which the traveling cost is taken into consideration by displaying the traveling number according to the current battery remaining amount of the vehicle as described above. Further, in order to make it possible to sensuously understand the distance of each facility and the current battery remaining amount itself, various distances are displayed with the current battery remaining amount for each specific facility as described above.

  When the list is arranged in the specific facility round trip possible number order 23, the calculation result of the specific facility round trip travel number 5 in the travel possible number calculation display unit 4 in the electric vehicle traveling battery remaining amount display processing unit 2 is used. To do.

  In the arbitrarily designated facility 24 in the specific facility selection list display unit 18, in addition to displaying a list for selecting the specific facility and selecting an arbitrary facility from the list, the user directly inputs and designates the facility. I can also do that.

  The specific route selection list display unit 25 selects a plurality of facilities, and further specifies a traveling order as necessary, in addition to determining a destination to be traveled from the specific facility as described above. Then, when it is intended to determine the destination of the future, the specific route selection list display unit 26 displays the list. Here, when the travel history data stored in the travel history data storage unit 14 is used, for example, when it is detected that the user often goes home after passing through a specific facility when returning home from a company at work, etc. In addition, if the facilities change from time to time, the travel routes are displayed in a list.

  The display order selection unit 26 selects the order in which the list is displayed. In the order 27 of the travel history counts, the list is displayed in descending order of the number of travels. The number is displayed in order of how many times the route can be driven.

  The list display of the possible number of times of travel 28 is in the order of the required travel distance in many cases for the same purpose as the specific facility round-trip travel number of times order 23, but considering the travel cost of each route, In order to display the remaining battery level in an easy-to-understand manner, the screen is also displayed as described above. In addition, when arranging the list in the specific facility round trip possible number order 23, the calculation result of the specific number of route traveling times 6 in the possible traveling number calculation display unit 4 in the battery remaining amount display processing unit 2 during the electric vehicle traveling is used. .

  In the arbitrarily designated route 29, the user designates an arbitrary route in the same manner as in the arbitrarily designated facility 24, in addition to displaying the list using the travel history data when the specific route selection list display unit 25 is displayed. In preparation. Therefore, the user can specify the facility at an arbitrary position in an arbitrary order. Here, when the user designates traveling in an arbitrary facility in an arbitrary order, the function of the recommended route 30 enables the traveling to be performed at the shortest distance or considering traffic congestion with the designated facility as a transit point. The route is calculated, and when a recommended route exists, it is presented.

  In addition, FIG. 1 shows an example in which the remaining battery level is displayed based on the number of times that the battery can travel back and forth to a specific facility or the number of times that a specific route can travel. When trying to select it, it is displayed that the vehicle cannot run or needs to be charged in the middle, and a warning sound or warning guidance can also be output.

  In the electric vehicle battery remaining amount guide display device of the present invention composed of the functional blocks as described above, for example, it can be implemented by sequentially operating according to the operation flow shown in FIG. 2 and the subsequent flow shown in FIG. it can. Below, based on the operation | movement flow, the action | operation of this invention is demonstrated in order.

  In the example of the electric vehicle battery remaining amount running count display process shown in FIG. 2, the process is started by first turning on the power switch of the electric vehicle (step S1). Next, a guidance form for performing battery remaining amount guidance for the electric vehicle is initially set in a state where such a power switch is turned on (step S2). In other words, in the present invention, the battery remaining amount display processing unit 2 for electric vehicle traveling in FIG. 1 includes a battery remaining amount display format selecting unit 3, and the number of possible traveling times according to the remaining battery amount of the present invention in the traveling number calculation display unit 4. And the conventional display format in the travelable distance display unit 7 with the remaining battery level are selected, so that the initial setting is performed in advance in step S1. This initial set value does not disappear even if the power switch is turned off thereafter.

  After the initial setting by turning on the power switch of the electric vehicle as described above, when the power is turned on, including the state where the power switch is turned on again, is the reciprocable number of times guidance form selected? It is determined whether or not (step S3). When it is determined that the reciprocable number of times guidance form is not selected in the initial setting, the process proceeds to step S4, where it is determined whether or not the reciprocable number of times guidance form is selected. When the travelable number of times guidance form is selected, the process proceeds to step S5.

  On the other hand, in step S4, when the travelable number of times guide format has not been selected, the process proceeds to step S10, and the remaining battery level is displayed in the conventional travelable distance. This process is performed by the battery remaining amount display processing unit 2 for electric vehicle driving in FIG. 1, the battery remaining amount display format selecting unit 3 by the travelable distance display unit 7 and the one-way travelable distance 8 or the reciprocal travelable distance 9. The display is performed by various methods as described above. However, since FIG. 2 shows the process of displaying the battery remaining number of times that can be traveled originally, when the process of step S10 is being performed, the process returns to step S4, and this process is performed until the travelable number of times guidance form is selected thereafter. Continue to display.

  When it is determined in step S3 that the travelable number of times guidance form is selected, the process proceeds to step S5 when the travelable number of times guidance form is selected in step S4, and the current position is detected. Thereafter, in the example of FIG. 2, the accumulated travel history data is read and displayed in a list in order of the number of travels among all genre facilities that go directly from the current location (step S6), and then the number of times the vehicle can travel with the current remaining battery level in the list. Is displayed (step S7).

  That is, in the example of FIG. 2, when the vehicle power switch is turned on and the travelable number of times guidance form is selected in advance, the user immediately guides the facility with the largest number of travels from the current position in order of the number of travels. I am going to do it. As a result, when the user turns on the vehicle, a display indicating how many times the battery can be reciprocated with the current battery level is displayed immediately at a store, etc. Yes.

  For each facility that cannot run with the current remaining battery level, for example, as shown in FIG. 8 (a) and FIG. 8 (c) which is a partially enlarged view thereof, A display such as “Need to charge halfway” is displayed. In addition, when displaying the number of possible reciprocating travels during various operations described later or the number of possible travels for a specific behavior pattern, if the current battery level is not able to travel, the above-mentioned “necessary charging is necessary” as described above. Display. This display also serves as a warning display for the current battery level.

  Thereafter, in the example of FIG. 2, it is determined whether or not to perform battery remaining amount guidance based on the running pattern (step S8). That is, in the present invention, as shown in FIG. 1, since the display of the number of round trips to a specific facility and the display of how many times a specific route can be performed are performed, which process is performed here. It is discriminating. However, in step S6, since the current battery level is displayed immediately without any operation, in the illustrated example, an initial setting is made to display how many times a specific facility can be reciprocated. An example is shown.

  In step S8, in particular, when there is no instruction for battery remaining amount guidance based on the running pattern, the process proceeds to step S21 of FIG. 3 as it is, and when there is an instruction, the process proceeds to step S51 of FIG. 6 in step S11. When the process proceeds to step S21 in FIG. 3 in step S9, it is determined whether or not the destination is selected by genre while the display of the number of possible round trips to the specific facility is continued. In the example of FIG. 2, since the list display is performed in order of the number of times of travel among facilities of all genres in step S6, the process proceeds to step S25 in step S21 if it can be left as it is.

  On the other hand, in order to consider a more detailed destination, when it is desired to display a list for each genre, the process proceeds to step S22, and a genre selection instruction is performed using the nearest search function or the like. This state is shown in FIG. 7 (a). In the same figure, "genre selection" is displayed as "search for nearby facilities", and a state in which "market" is selected is shown. Yes. In the display mode switching processing, whether to select all-genre selection 19 or to select genre-specific selection 20 in the specific facility selection list display unit 18 in the travel destination selection list display unit 17 of FIG. It is switched by.

  Thereafter, in step S23, a list is displayed in the order of frequently visited facilities in the genre designated as described above. In other words, as shown in step S6 in the illustrated example, the initial setting for displaying a list of a plurality of facilities in order of the number of times of travel is performed. The list is displayed in the order of facilities.

  Then, it progresses to step S24 and displays the frequency | count which can be reciprocated by the present battery remaining charge about the facility displayed as a list. FIG. 7 (c) shows the state, and FIG. 7 (c) shows an example in which the genre of “market” is selected and displayed as described above in FIG. 7 (a).

  About the guidance display of each facility displayed as a list in FIG. 7C, for example, as shown in an enlarged view in FIG. 7B, the store is “Maruki YM store” along with the market icon, The store is 7 km from “Home” in the current location, which indicates that the current battery level can run 22 times.

  In the example of FIG. 3, it is then determined whether or not the display list is rearranged in order of the number of reciprocable times from the current location (step S25). That is, in the illustrated example, as described in the description of step S6 in FIG. 2, the initial setting is displayed in a list in order of the number of times of travel. It is determined whether or not it is better.

  When it is determined in step S25 that the current location is to be sorted in the order of the number of possible round trips, that is, when the user gives an instruction to that effect on the display order setting portion displayed on the monitor, the process proceeds to step S26, and the display list is returned from the current location. Sort in as many times as possible. The order of the number of possible round trips from the current location is in the order of the distance from the current location in many cases as described above, but in addition to the order in which travel costs etc. are taken into consideration, it is not the order of the mere distance There is.

  When this display format is selected, in addition to the distance from the current location of each facility, the positional relationship of each facility with respect to the current battery level is displayed in order of the number of round trips possible with the current battery level. The battery remaining amount display that is easy to understand and the positional relationship from the current location of each facility can be displayed. In particular, in the guidance display of a plurality of facilities based on the number of possible round trips, travel costs such as travel time are taken into account due to travel speed restrictions according to the road width when going to each facility, in addition to simple distance comparison. , The relationship between each facility and the current location can be displayed more clearly.

  Thereafter, when it is determined in step S25 that the display list is not rearranged in the order of the number of round-trips possible from the current location, the process proceeds to step S27, and it is determined whether or not the user designates an arbitrary facility. Similar to the above, this determination can be made by detecting that the user has made the instruction by an instruction to display “Destination Input” or the like displayed on the screen.

  When the user instructs to designate an arbitrary facility in step S27, the process proceeds to step S28, and the user designates an arbitrary facility. The designation at this time can be instructed, for example, by touching the icon of each facility shown on the map or by searching for nearby facilities as shown in FIG.

  Thereafter, as in the above-described processes, the number of round trips with the current battery level is displayed in the list. In many cases, only one facility is displayed on the list at this time, and the number of round trips for the facility is displayed. Next, when it is determined in step S27 that the user does not designate any facility, the process proceeds to step S30 and waits for the vehicle to start running in step S31 of FIG.

  When the vehicle starts to travel in step S31 of FIG. 4, a travel history data accumulation process as shown in FIG. 5 is performed in step S32. Various methods have been conventionally proposed as the travel history data accumulation processing method. In the example of the travel history data accumulation processing shown in FIG. 5, the set destination and waypoint are first stored (steps). S41).

  Thereafter, the travel route is stored every predetermined time (step S42). Next, it is determined whether or not the vehicle has stopped (step S43). When the vehicle has not stopped, the process returns to step S42 to continue recording the travel route every predetermined time. On the other hand, when it is determined that the vehicle has stopped, in the illustrated example, it is determined whether or not the vehicle has started running between the lower limit predetermined time such as 10 minutes and the upper limit predetermined time such as 3 hours after the stop.

  The lower limit predetermined time at this time is set to a time at which the user performs shopping at a convenience store, for example, and can be set to an arbitrary time such as 5 minutes in addition to 10 minutes as described above. Similarly, the upper limit predetermined time considers the time that the user spends time on, for example, lessons, and therefore can be set to any time such as 2 hours in addition to the above 3 hours. . These times may be learned and stored in the same place when the same time is always taken at the same place during daily running, and the time may be set with a certain margin.

  When it is determined in step S44 that the vehicle has started traveling within the lower limit predetermined time and the upper limit predetermined time after stopping, the process proceeds to step S49, and the point where the vehicle has stopped this time is stored as a stopover point. That is, the predetermined time is a stop for some purpose, is not considered as a stay destination such as staying at a hotel, and is determined to be a stopover point as a stopover point, and is used as action pattern data. Remember as. Here, when the stop position is a pre-registered home or company, it is not stored as a stop-off point.

  On the other hand, when it is determined in step S44 that the vehicle has not started running within the lower limit predetermined time and the upper limit predetermined time, the process proceeds to step S45, and it is determined whether or not the stop is less than the lower limit predetermined time. Here, for example, when it is determined that it is less than the lower limit predetermined time such as 10 minutes, it is determined that the stop there is a temporary stop without a special purpose, and the process returns to step S42 to store the travel route every predetermined time. Continue.

  In addition, when the behavior patterns as described above are accumulated, when the vehicle frequently stops at the same place, the place is memorized as a regular stop-off place, and then at that place, for example, 3 minutes or 4 hours, etc. Even if it is other than the above lower limit and the upper limit predetermined time as described below, it is stored as having stopped at the stop point.

  When it is determined in step S45 that it is not less than the lower limit predetermined time, the stop is longer than the upper limit predetermined time such as 3 hours or more, and in this case, the process proceeds to step S46, and this point is stored as the final point of the series of travel patterns. To do. That is, here, even if the vehicle stops for a predetermined time such as 3 hours or more, even if it is a place other than home or office, a series of travel history is stored as a travel pattern with the current stop position as the final destination.

  By performing the action pattern data accumulation process as described above, for example, various data as shown in FIG. 9D as examples of the data items are accumulated. A variety of vehicle-specific driving pattern and behavior pattern data can be obtained by creating processing data.

  In step S32 of FIG. 4, the above-described processing for accumulating the travel history data is periodically performed while the vehicle is traveling, including data on stopovers, and then for a long time such as at home or at a company. It is determined whether or not the vehicle has arrived at a specific point that is registered in advance as being a place where the vehicle is stopped, and charging is also possible. Here, when it is determined that the user has not arrived at a specific point such as home or office, the process returns to step S32 to continue the accumulation of data as described above.

  If it is determined in step S33 that the vehicle has arrived at a location where the vehicle has been registered for a long time, such as at home or at the office, where charging is possible, the process proceeds to step S34, and the current and future dates will be based on the action pattern data. It is determined whether or not there is a vehicle use schedule.

  The action schedule is obtained by accumulating various data as shown in FIG. 9 (d) by the travel history data accumulating process as shown in FIG. 5, for example, FIG. 9 (a). ) You can know the behavior pattern as shown on the calendar. This behavior pattern is shown as an example of a traveling schedule of a vehicle that a housewife uses almost for herself.

  In the example of the behavior pattern shown in the figure, this housewife shows that he / she does not drive on Saturday and Sunday, does shopping on Monday, Wednesday and Friday, and goes to study on Tuesday and Thursday. . Even if you don't know the purpose of the travel, you can see that such behavior patterns travel to the same place every week at the same time, stop for a certain amount of time, and return to your home. Therefore, behavior pattern data as shown in the illustrated calendar can be obtained.

  In the example shown in FIG. 9 (a), when it is currently Wednesday on the 13th and it is detected in the step S33 of FIG. Then, it is determined whether or not there is a plan to use the vehicle in the near future from the behavior pattern data, and it is understood that there is no plan to run today, and that there is a plan to run for 14th tomorrow on Thursday.

  In that case, in step S34 in FIG. 4, it is determined that there is a plan to use the vehicle in the near future, and the process proceeds to step S35, and the number of times of traveling to the facility scheduled from now on is the current battery level. Calculate whether you can reciprocate. After the calculation, the process proceeds to step S36, and it is determined whether or not traveling to the facility to be scheduled with the current battery remaining capacity is reciprocable.

  When it is determined in step S36 that it is possible to travel to the facility planned for the current battery level, the process proceeds to step S39, for example, as shown as a display example (1) in FIG. Tomorrow is Thursday. With the current battery level, you can drive to the usual place 12 times. ” In addition, when the user has registered in advance, such as “Perform △△ on XX days,” “Tomorrow is Thursday. With current battery level, home ⇒ lessons ⇒ 12 trips to home. It is also possible to display “You can do it.”

  Further, when it is determined in step S36 that the current battery level is low and traveling on Thursday is not possible, the process proceeds to step S37, and the current battery level will interfere with the future driving schedule, so it is necessary to charge. Output a warning that there is. Fig. 9 (c) shows an example of a warning display to that effect. In the example shown in the figure, "Tomorrow is Thursday. Because it is difficult to travel to the usual place with the current battery level, charge the battery. Please give me a warning. "

  In this display, if you register in advance to go to “learning” on this day of the week, you can display “... home → learning → because it is difficult to travel to home ...” . When such a warning display is performed, it is more preferable to perform the same output by voice at the same time in consideration of the user overlooking such a display.

  When the vehicle stops at home as described above, the travel history data can be used to inform the need for charging in consideration of future travel schedules. On the other hand, if the family suddenly gets off the vehicle and suddenly gets off the car, the charging timing will be changed, the user will forget to charge and the usual driving of the next day will be prevented as much as possible. Will be able to.

  In the example shown in FIG. 9, in the case of an action pattern up to the 19th with the current remaining battery level, it is better to charge if it is possible on the 20th and 21st, and then on the 22nd one way or on the way Therefore, it is possible to know from the above data that the vehicle cannot run unless it is charged after 25th.

  After the warning output as described above is performed in step S37, when it is determined in step S34 that there is no vehicle use schedule in the near future due to the behavior pattern data, and in step S38, to the future planned facility. At the same time, the process proceeds to step S39, returns to step S2 in FIG. 2, and waits for the next power switch to be turned on in this electric vehicle.

  On the other hand, when it is determined in step S8 in FIG. 2 that the remaining battery amount guidance is performed based on the running pattern, the process proceeds to step S51 in FIG. 6 (step S11), and the remaining battery amount guidance based on the traveling pattern is performed as shown in FIG. That is, instead of performing a list display for selecting a facility to travel back and forth with a specific facility as a destination in step S7 as described above, for example, return to home using a specific facility or the like while returning from the company. For example, when it is desired to give an instruction to display a list of traveling patterns, the operation of FIG. 6 is performed. At the time of selection, the display mode is changed by instructing the display portion of “change to display by running pattern” on the screen in the state where the display as shown in FIG. Can do.

  In the example shown in FIG. 6, a list is displayed in the order of frequently used driving patterns among the behavior patterns in the first current location, and how many times the driving pattern can be driven with the current battery level in the list. Is displayed (step S51). At this time, if there is only one traveling pattern that is frequently used, it is natural to display only that, and here, this is also regarded as a list display.

  In the display at that time, for example, as shown in FIG. 8 (c), the behavior pattern data storage processing indicates that the user's behavior pattern often takes an action of "Home⇒Company⇒Rene Sport⇒Home". In the illustrated display example, the location of each facility that travels is displayed on the map only for this behavior pattern, and for each facility, as in FIG. 7C, for each facility. Displays the number of round trips that can be performed with the current battery level, and displays the behavior pattern of “Home⇒Company⇒Rene Sports⇒Home” along with the icons of each facility as another list display. Shows an example of displaying “stroke 22 km, travel possible 5 times”.

  When it is determined in step S52 that the user does not go to a place other than the behavior pattern displayed in the list, the process proceeds to step S61, and any one of the behavior patterns displayed in the list is designated. At this time, if there is only one action pattern as described above, this can be confirmed and designated by indicating the action pattern display portion.

  In step S52, if the user does not perform the usual behavior pattern illustrated above as described above and intends to go to a specific place, the process proceeds to step S53 to sequentially specify the scheduled travel points. To do. At this time, for example, as shown in FIG. 8C, the operation mode is set by instructing a display portion of “specify another behavior pattern”, and an input operation for sequentially specifying the planned travel point is performed.

  After that, the designated action pattern displays how many times the vehicle can run with the current battery level (step S54). Next, in the example shown in FIG. 6, it is determined whether or not there is a recommended route in consideration of traffic jam, distance priority, etc. (step S55). In this process, when the user sequentially designates the scheduled travel points in step S53, the route that returns to the home from the company is calculated through all the facilities designated by the navigation device, and the travel cost is the lowest among them. Alternatively, when there is a route with a short travel time, it can be determined by determining whether or not to display the route.

  If it is found in step S55 that there is a recommended route in consideration of traffic jams and distance priority, the process proceeds to step S56, and the recommended route is displayed together with the number of times the vehicle can run with the current remaining battery level. This state is shown in FIG. 10 (a). In the example shown in the figure, a plurality of facilities are directly set on the list display screen of facilities frequently visited from the home that is first displayed on the screen when leaving the house by commuting. When a screen for setting a travel route is displayed and an instruction to travel in the order of (1) to (5) is given, a recommended route is presented.

  That is, in the example shown in FIG. 10, when leaving home, unlike today's usual route, when you want to stop by "Yo Kido" and "Evilia" on the way home from the office, (1) (2) Company, (3) Yokodo, (4) Maruki YM store, (5) Example in which instructions are given in the order of home.

  Here, in the example of the figure, as a result of examining the route designated again by the navigation device, the route from the home to the company is not changed, and from the positional relationship on the road between “Yokido” and “Maruki YM store” When you go to “Maruki YM store” after going through “Yokido” and return to your home, the process is 26km, and you can go back and forth 6 times with the current battery level, but after you stop at “Maruki YM store” When going to “Yokido” and returning home, the distance is 22 km, and an example of displaying that it can be run 7 times with the current battery level is shown. FIG. (B) shows an explanatory diagram thereof.

  In the example of FIG. 5, after determining in step S55 that there is a recommended route considering traffic congestion, distance priority, etc. as described above, in step S56, this is displayed together with the number of possible travels as shown in FIG. In step S57, it is determined whether or not the user has selected a recommended route. Here, when the user selects this by, for example, instructing the display part of the recommended route on the screen, the process proceeds to step S59 to determine whether or not the determined route can be driven with the current battery level, When the vehicle is not capable of running, the battery level is insufficient, so a warning is output that charging is required on the way. Also in the warning output at this time, it is preferable to output a warning sound or warning voice in addition to displaying on the screen as described above.

  When it is determined in step S57 that the user has not selected the recommended route, that is, when the user designates a route guidance screen portion designated by the user on the screen of FIG. When it is determined that there is no recommended route taking into consideration, the process proceeds to step S62, and the same route as the travel history is determined. After that, it is determined that the user does not go to a place other than the action pattern displayed in the list in step S52, and after specifying any action pattern displayed in the list in step S61, the process proceeds to step S59. Check the warning output according to the remaining amount. Thereafter, the process proceeds to step S31 in FIG. 4 in step S63, and the various operations after traveling the vehicle are performed as described above.

  In the present invention, it can be implemented in various modes as described above. Further, for example, when there is a charging station in the vicinity of the vehicle or in the vicinity, a traveling route that considers charging at the charging station is It can be implemented in various other ways, such as displaying with the number of times the vehicle can travel according to the remaining battery level.

  In addition, the electric vehicle battery remaining amount guide display device of the present invention can directly implement the various aspects as described above when applied to a navigation device, but the basic technical part of the present invention is as follows. For example, it can also be implemented by performing various displays on the display part by incorporating it in the head unit of the vehicle, and by using various functions such as a map display function of the portable device by communicating with the portable device, It can also be used as a system, such as performing various displays on the display portion.
