Electric power source selector 3 and a plurality of charging terminal 9 couplings.Each terminal 9 is coupled with electric power source A-C separately via electrical power circuit.In this case, each charging terminal 9 is via the corresponding terminal coupling of corresponding electrical power circuit and electric power source A-C.Thereby terminal 9 is not coupled with the not corresponding terminal of electric power source A-C.Electric power source A-C can be the commercial electrical power source being provided by electric power utilities, the electric power source being provided by solar photovoltaic generating, the electrical power being provided by wind power generation or the electric power source that provided by the indoor power generating equipment of using gas or fuel cell.In this embodiment, commercial electrical power source and the electric power source being provided by solar photovoltaic generating are provided electric power source A-C.Solar energy photovoltic power system is arranged on the roof in house or garage.When solar energy photovoltic power system generates electric power, this solar energy photovoltic power system is supplied to electrical power the equipment in house.At solar energy photovoltic power system, when the terminal in house is switched to a plurality of charging terminals 9, and compare to house power supply, this solar energy photovoltic power system is paid the utmost attention to vehicle is charged.After completing the charging of vehicle, the terminal that be switched to house of solar energy photovoltic power system from a plurality of charging terminals 9.

Electric power source selector 3 comprises the electric power transducer with transformer.By transformer, a selected electrical power providing from a plurality of charging terminals 9 being converted to will be to certain electrical power of battery 4 chargings.In addition, electric power source selector 3 comprises for detection of the voltage sensor of voltage and for detection of at electric power transducer be connected to the current sensor of the electric current of the supply path between the lead-out terminal of battery 4.Charge controller 2 be take the amount of electrical power that the electric current that detected and voltage will be charged to battery 4 and will discharge into drive motors (not shown) as basic calculation.Thereby charge controller 2 detects and is filled with the current charged electrical quantity of power in battery 4.In this case, in battery 4, charged electrical quantity of power shows the amount of electrical power that will consume while only using first battery 4 operation after a plug-in hybrid vehicle in the end charging.

Owing to using the gain-of-function in navigator 5 to be used to form the information of carrying out the charging scheduling that the charging of battery 4 is controlled, therefore charge controller 2 is arranged in navigator 5.In the present embodiment, by the processor of navigator 5, carry out the function in charge controller 2.By the processor of navigator 5, carry out by route calculation and estimate that element 6, weather forecast obtain the function that element 7, sun set/raise time data acquisition element 8 etc. are carried out.

Route calculation estimates that element 6 arranges the best route from the current location of vehicle to destination when being provided with destination.In addition, route calculation estimates that element 6 calculates advance back and forth between current location and the destination electric power consumption of needed estimation of batteries 4.

Weather forecast obtains element 7 weather forecast that uses digital radio electric wave to provide from the external information center such as radio broadcasting station or data service center is provided.Weather forecast is widely used as broadband connections.Weather forecast obtains the weather forecast of next day of the definite estimated date as next driving plan of element 7.

8 storages of sun set/raise time data acquisition element corresponding with longitude and latitude at sunrise between and sunset time.Sun set/raise time data acquisition element 8 provide about the longitude shown in the gps data with being obtained by navigator 5 and latitude corresponding at sunrise between and the information of sunset time.Because sun set/raise time data are normal datas corresponding with longitude and latitude, therefore preferably consider by the current location and the light shield effect at the sunshine that the barrier between the sun produces that are arranged on vehicle.Barrier is arranged on day outgoing direction and the sunsetting of watching from vehicle.For example, when vehicle set is in high mountain region, preferably consideration is positioned at the light shield effect of the high mountain of vehicle periphery.When vehicle set is in urban area, preferably consideration is positioned at the light shield effect of the building of vehicle periphery.In addition, even in solar energy photovoltic power system is arranged on to same area time, owing to irradiating the irradiation time section of the illumination of solar energy photovoltic power system and may depend on the setting position of solar energy photovoltic power system.Thereby can be inputted by user the irradiation time section of solar energy photovoltic power system.

In user indication, battery 4 is charged to prepare once whilst on tour, user under a plurality of charging terminals 9 of plug-in vehicles 1 are connected to from the condition of the electrical power circuit of solar energy photovoltic power system and business power source navigation device 5 inputs about on the information of travelling once.Navigator 5 be take time started and the destination scheduling of charging as basis of input, and then navigator 5 starts battery 4 to charge.

Fig. 2 shows the flow chart that represents the charging process carried out by navigator 5.Navigator 5 checks the residual capacity of battery in charge controller 2 in steps A 1.Next, in steps A 2, charge controller 2 calculate on next day or next time on the essential amount of electrical power of once driving.

Fig. 3 shows the flow chart of the calculating of the essential amount of electrical power for drive next time.In step B1, charge controller 2 determines whether user is provided with the route such as the time of advent of destination and estimation.Charge controller 2 determine user in navigator 5, be provided with on once drive route time, step B1 be judged as "Yes" time, the best route that navigator 5 is calculated from current location to destination.In addition, navigator 5 be take distance between current location and destination and be the basic calculation required essential amount of electrical power Y that advances back and forth between current location and destination about the data of fuel consumption and/or electric power consumption amount.In this case, the best route from current location to destination be vehicle once travelled route time, by safety factor and actual electric power consumption at that time being multiplied each other obtain the electric power consumption amount of the estimation of the best route between current location and destination.Although on the best route once driven be vehicle once along it, from current location to destination, travelled route time, the past data that the actual electric power of this route is consumed is as the electric power consumption amount of estimating, but when vehicle does not also travel along this best route in the past or when vehicle partly travels along this best route in the past, navigator 5 is calculated the electric power consumption amount of the estimation for drive next time.Specifically, navigator 5 when vehicle travels along a part for best route in the past by utilizing the past data of actual electric power consumption of a part for this best route to calculate the electric power consumption amount of estimation.When vehicle does not travel along the other parts of this best route or whole best route in the past, navigation system 5 is by utilizing the data of sideways inclined angle in map datum and the existence of traffic lights etc. to calculate the electric power consumption amount of estimation.Here, sideways inclined angle is the angle of inclination of upward slope or the descending of road.Specifically, at best route, comprise while going up a slope, navigator 5 is by from vehicle, the electric power consumption amount when flat road travels increases and calculates the electric power consumption amount of estimation according to the amount of electrical power of the distance estimations of sideways inclined angle and upward slope.When optimum line comprises descending, navigator 5 is calculated the electric power consumption amount of estimation by the electric power consumption amount of estimation being reduced to the amount of electrical power of regeneration.When optimum line comprises many traffic lights, electric power consumption amount is because the quantity stopping increases greatly.Thereby navigator 5 is calculated the electric power consumption amount of estimation by increasing according to the quantity of traffic lights the electric power consumption amount of estimating.In addition, navigator 5 by consider speed restriction in this route, the quantity of runway, the distance of straight line road, prediction next drive day or during the traffic congestion of next driving time etc. the distance of traffic congestion calculate the electric power consumption amount of estimation.In addition, at best route, comprise tunnel, or next driving time is while comprising the time at night after the sunset, need to turn on lamp, and the electric power consumption amount of therefore estimating increases.

Then, navigator 5 be take route calculation result and as basis, is calculated the time of advent of estimation and required driving time.Navigator 5 be take time of advent of estimating and required driving time and is estimated the time started as basis.For example, be points in the mornings 9 time of advent of estimation, and required driving time is one hour, and be 50KW for arriving the essential amount of electrical power of the round trip of destination.Here, can be when object is located in for battery 4 charging, user arranges one way route in navigation system 5, and in this case, essential amount of electrical power is half of round trip.

When user uses vehicle 1 conduct to travel frequently vehicle, destination is identical, and best route is identical.Thereby, easily estimate essential electric power consumption amount.For the electric weight of laying in vehicle 1 is for the work of travelling frequently or the essential and sufficient amount of electrical power of going to school, navigator 5 can comprise the charge switch for the (not shown) of travelling frequently on the screen of display.Thereby, by only pressing a button, i.e. the charge switch for travelling frequently, it is to travel frequently that chance is driven in the easy setting of user next time.Therefore,, in step B3, navigator 5 determines whether user has opened the charge switch for travelling frequently.When navigator 5 determines that user has opened the charge switch for travelling frequently, step B3 be judged as "Yes" time, the past data of some day, weather forecast and actual electric power consumption that navigator 5 be take a week in step B4 calculates essential amount of electrical power as basis.In this case, at Commuting Distance relatively in short-term, and therefore only just can adequate preparation must amount of electrical power time by solar energy photovoltic power system, charge controller 2 can control from sunrise to time started, only to use solar energy photovoltic power system to charge to battery 4.In this case, charging cost is minimum.

Near the destination of input is positioned at current location relatively, and/or the time started of scheduling is relatively late, while only making by just can the adequate preparation essential amount of electrical power of solar energy photovoltic power system, because charge controller 2 can control only use solar energy photovoltic power system to charge to battery 4 from sunrise to the time started of scheduling, so charging cost is minimum.Even only by solar energy photovoltic power system during with regard to the essential amount of electrical power of adequate preparation, preferably, by day during,, during sunshine hour, farthest use solar energy photovoltic power system to charge to battery.

When user does not arrange route, step B1 be judged as "No" time, and user does not open the charge switch for travelling frequently, step B3 be judged as "No", navigator 5 be take calendar and as basis, is come estimating user whether to use the vehicle for travelling frequently.Specifically, when next day is working day, navigator 5 hypothesis users use the vehicle for travelling frequently at next driving time.When next day is day off or holiday, because user can not use vehicle, be not used for travelling frequently, so charge controller 2 controls that battery 4 is fully charged.

Next, in the steps A 3 of Fig. 2, navigator 5 is prepared charging operation plan.

Fig. 4 is the flow chart that the preparation of charging operation plan is processed.Navigator 5 determines in step C1 whether user arranges the time started of scheduling.When navigator 5 determines that user is provided with the time started of scheduling, step C1 be judged as "Yes" time, equipment 5 obtains the weather forecast of next day or next time from information centre, and in step C6, determines whether this weather forecast represents fine weather.When weather forecast represents fine weather, step C6 be judged as "Yes" time, the table data that navigator 5 be take in the equipment of being stored in 5 generate for example electric power of 10KW/h as basis hypothesis solar energy photovoltic power system.Even if this average electric power that generates also depends on date and time section when weather is fine.Specifically, in the charging interval, approach sunrise or at sunset, on average generate electric power little, and the charging interval at noon near time, on average generate electric power maximum.Thereby table data comprise according to the detailed data of the average generation power of data and time period.

Equipment 5 be take calendar as the basis acquisition date of next day.In addition, equipment 5 with the sunrise in the equipment of being stored in 5 and sunset time table data acquisition next day at sunrise between and sunset time.Sunrise and sunset time table data show position (being longitude and latitude) in the country at Japan or vehicle place and the relation between sunrise and sunset time in this date.For example, between at sunrise, be points in the mornings 6, and time started of scheduling while being 8 a.m., before leaving, the power generation time of solar energy photovoltic power system is two hours from 6 in the morning to 8 a.m..Thereby by being multiplied by the charge volume that 10KW/h calculates electric power by two hours, thereby the charge volume of electric power is 20KW(=10KW/h * 2h).Therefore, because the essential amount of electrical power of the round trip to destination is 50KW, therefore need to be during night, before sunrise, to battery charging 30KW(=50KW-20KW).

When business power source is battery charging 20KW/h, need to use before sunrise this business power source for 1.5 hours (=30kW/20KW/h) of battery 4 chargings.In this case, due to business power source in the time period at night than the kiowatt low price in time period by day, the charging cost of business power source is in the time at night, specifically at midnight, more cheap than time by day.Thereby equipment 5 determines that whether the time period at night of business power source is wider than one and a half hours.When wider than 1.5 hours in time period at night of business power source, equipment 5 is prepared charging operation plan so that use time at the night electric power from business power source to charge to battery 4 in step C7.Using the required charging interval of business power source when the night of business power source, the time period was large, when narrow than 1.5 hours in time period at night of business power source, equipment 5 is prepared charging operation plans so that use from time at the night electric power of business power source and use the normal electricity (being time on daytime electric power) from this business power source to be filled with the difference between required charging and the charging of time at night electric power in remaining time in section in the time period at night.

At equipment 5, determine in step C6 while determining that weather forecast does not represent fine weather, step C6 be judged as "No" time, solar energy photovoltic power system can fully not charge to battery 4.Thereby equipment 5 is prepared charging operation plan so that use time at the night electric power from business power source to charge to battery 4 in step C8.In this case, using the required charging interval of business power source when the night of this business power source, the time period was large, equipment 5 is prepared charging operation plans so that use from time at the night electric power of business power source and the difference that is filled with between required charging and the charging of time at night electric power from the normal electricity (being time on daytime electric power) of business power source in section use remaining time battery 4 is charged in the described time period at night.

Equipment 5 determines in step C2 whether user has pressed the charge button of travelling frequently, and equipment 5 determines whether user has opened the charge switch for travelling frequently.In addition, equipment 5 step C2 be judged as "No" time in step C4, determine whether next day is working day.User, opened while travelling frequently charge button, step C2 be judged as "Yes" time, or when next day is day off, step C4 be judged as "Yes" time, proceed to step C3.In step C3, equipment 5 provides the commuting time of every day.Then, proceed to step C6.In step C7 and C8, equipment 5 be take weather forecast as basis preparation charging operation plan.When next day is not working day, when next day is holiday or day off, step C4 be judged as "No" time, proceed to step C5.In step C5, equipment 5 be take the driving history of holiday and is that basis estimates the time started of driving.Then, proceed to step C6.In step C7 and C8, equipment 5 be take weather forecast as basis preparation charging operation plan.

When the weather forecast of next day represents cloudy or rainy day, solar energy photovoltic power system does not charge to battery 4 substantially.In this case, the charging from solar energy photovoltic power system is substantially zero.Then, equipment 5 is prepared charging operation plan so that farthest use time at the night electric power from business power source to charge to battery 4.Equipment 5 supposition users, operate rain brush at rainy day or cloudy weather in the situation that and/or turn on the lamp of vehicle and/or during operating air conditioning system, need to prepare charging operation plan to increase the electric power consumption amount of estimating.

Thereby, take this charging operation plan as basis, farthest utilize solar energy photovoltic power system to charge to battery 4, when the charge volume from solar energy photovoltic power system is not enough, business power source is used the deficiency of time at night supply of electric power charge volume, and in addition, at the charge volume from solar energy photovoltic power system with when enough from the charge volume of use time at the night electric power of business power source, use electric power normal time (being time on daytime electric power) from business power source, battery 4 to be charged.

Fig. 5 shows the example of charging operation plan.

In Fig. 5, from morning, 1:00 charges to battery 4 from business power source to 2:30 use in morning time at night electric power.From the morning 6:00 to the morning 8:00 utilize solar energy photovoltic power system to charge to battery 4.From the morning 8:00 to the morning 9:00 Vehicle Driving Cycle to destination.

Equipment 5 switches electric power source selector 3 so that switch the electric power source for battery 4 is charged between solar energy photovoltic power system and business power source.

Actual charged electrical quantity of power in this time period very hour, in this time period, solar energy photovoltic power system charges to battery 4, equipment 5 is automatically switched to business power source from solar energy photovoltic power system.Thereby even if weather forecast makes a mistake, equipment 5 also protects impact that battery 4 avoids charge volume deficiency so that vehicle normal driving.

In addition, at the next one, drive 1 o'clock after scheduling day being next day, at this, next day only charged to battery 4 by solar energy photovoltic power system, and then, navigator 5 can be take the charged electrical quantity of power of the time battery after the sunrise of at this next day and as basis, prepared at this one day and new charging operation plan of this next day after next day.

In the present embodiment, obtain following effect.

It is that basis obtains the electric power consumption amount of driving essential estimation in the next time that navigator 5 be take the time of advent and the destination of estimation of the next driving time inputted by user.Take next driving time at sunrise between and sunset time and weather forecast be basis, until before the time started of scheduling, equipment 5 is formed for the charging operation plan that farthest uses solar energy photovoltic power system to charge to battery 4.Because equipment 5 is controlled according to charging operation plan, battery 4 is charged, reduced charging cost.In addition, in the charged electrical quantity of power from solar energy photovoltic power system, be compared to once the electric power consumption amount hour of the essential estimation of driving time, from business power source, battery 4 charged.Thereby, fully guaranteed for the electrical power of driving time next time.

Owing to using time at night electric power to charge to battery 4 by business power source, therefore reduced charging cost.

In addition, equipment 5 consider current locations at sunrise between and sunset time and the operation plan of preparing to charge, and therefore, even if all farthest utilize solar photovoltaic generating to charge to battery 4 when the current location of vehicle is arranged on any longitude and latitude.

Because equipment 5 comprises for obtaining the function of current location information and/or weather forecast, therefore can easily obtain current location information and weather forecast.

(the second embodiment)

With reference to Fig. 6, Fig. 7 A and Fig. 7 B, explain the second embodiment.In the first embodiment, the new destination of the next driving time of essential input.Recently, schedule information is input in advance have comprise Bluetooth function scheduling feature such as mobile personal computer, PDA(personal digital assistant) and cellular mobile communication equipment in so that the date that this mobile communications device management is gone out and position.In navigator 5, input scheduling information is again unnecessary.In addition user's input scheduling information mistakenly again in navigator 5.

In the present embodiment, navigator 5 obtains element as schedule information, in compartment user at vehicle when thering is the mobile communication equipment of Bluetooth function, from the described mobile communication equipment with Bluetooth function (this schedule information obtains element, scheduling controller) receive, obtain the schedule information of input in advance.Thereby in the schedule information that represents the destination of vehicle, while representing that user is present in mobile communication equipment to the schedule information of the use of vehicle, the going-out information in equipment 5 schedule informations is set to destination.In this case, when schedule information comprises a plurality of destinations for going out or a plurality of time or many days, i.e. the use of vehicle, in equipment 5 schedule informations, nearest going-out information is set to destination.In addition,, during a plurality of going-out information in schedule information comprises on the same day, while comprising a plurality of destination, the going-out information in equipment 5 schedule informations is set to destination according to the order of the distance apart from current location.Thereby equipment 5 determines whether user utilizes the use of vehicle and going-out information is registered as to destination.Equipment 5 for execution scheduler with management going-out information.

Fig. 6 shows the data structure of the scheduler in mobile communication equipment.The data structure of scheduler comprises position and the main body of event title, date, event time started, end time, event.In the present embodiment, will judge whether user uses the mark of vehicle to be increased to scheduler for inputting.Moving vehicle be labeled as " 1 " time,, when being judged as "Yes", user uses vehicle (that is, automobile) to move to destination, the position arranging.This destination is registered in scheduler.

When user enters in the vehicle with the mobile communication equipment that comprises the scheduler of registering schedule information, navigator 5 is used Bluetooth function to obtain the schedule information of registering in mobile communication equipment.In this case, when schedule information comprises the data of mark of the moving vehicle with 1, navigator 5 is used the data dispatching in navigator 5 to replace the schedule information obtaining from mobile communication equipment as possible, that is, make to synchronize with the data dispatching navigator 5 from the schedule information of mobile communication equipment acquisition.When navigator 5 is used Bluetooth function as possible the data dispatching the schedule information obtaining from mobile communication equipment and navigator 5 to be integrated,, the schedule information obtaining from mobile communication equipment is synchronizeed with the data dispatching navigator 5, and SYNC(is synchronous in use) as the configuration standard of Bluetooth function.Thereby, navigator 5 next driving time storage purpose with scheduling the event time started (that is, the time of advent of estimation).

Navigator 5 is calculated the time started of estimating, at the time started place of this estimation, vehicle be take in equipment 5 destination of registration and start to travel towards destination as basis the time of advent of scheduling.Similar with the first embodiment, equipment 5 is prepared charging operation plan.In this case, because the event time started means that user starts to do in destination some things from this event time started, therefore preferably, between event time started of event and the time of advent of destination, increase such as the halfhour scheduled time, and then calculate time departure (that is, time started).

At vehicle from go back home in destination and user at equipment 5 from the condition of mobile communication equipment receiving scheduling information and registration schedule information during the engine of stop vehicle, all finishing scheduling of going out that navigator 5 was determined in this day.As shown at Fig. 7 A, it is that basis prepares nextly to drive scheduling that equipment 5 be take the schedule information that obtains from mobile communication equipment, and on display 11, shows that this next one drives scheduling.In Fig. 7 A, display 11 shows next date and scheduling content of driving scheduling, and this represents that user uses vehicle in the next time.In addition, display 11 shows that OK button 12 and scheduling change button 13.The basis that is scheduling to that OK button 12 represents to show inquires that whether preparing charging dispatches.Scheduling changes the input that button 13 indicates to change the instruction of dispatching.Whether suitable OK button 12 and scheduling change button 13 with corresponding for selecting charging to dispatch selectors.When user opens OK button 12, equipment 5 is prepared charging scheduling with the basis that is scheduling to showing.When not obvious in next destination or when displaying contents is incorrect so that user opens scheduling while changing button 13, another image by the image switching of Fig. 7 A on display 11 to Fig. 7 B.In Fig. 7 B, on display 11, show that the message 14 of " asking input scheduling " replaces scheduling to change button 13.Thereby user selects (that is, touching) to represent that user wants a part for the image of the information that changes, and then user uses button (not shown) to change this information.Button is corresponding with correcting element.In this case, after user's change is stored in the scheduling in navigator 5, the schedule information in mobile communication equipment can be synchronizeed with the scheduling changing in navigator 5.Alternatively, the schedule information in being stored in mobile communication equipment can be synchronizeed the scheduling being stored in navigator 5 after changing with the schedule information changing in mobile communication equipment.

(the 3rd embodiment)

With reference to Fig. 8, explain the 3rd embodiment.In the first embodiment, according to the angle of inclination of road obtaining from map datum and the existence of traffic lights, carry out the method for using the Japan-China electric power consumption amount of estimating at the next one of vehicle for calculating.Yet, may be not enough from the data accuracy of map datum.Specifically, with the map datum being stored in navigator 5, obtain a part for the route also not travelling about vehicle or whole information of this route.Yet the map datum in navigator 5 may be offhand for calculating electric power consumption amount.Thereby, may calculate irrelevantly the electric power consumption amount of estimation.

In the present embodiment, in order to improve the counting accuracy of the electric power consumption amount of estimation, from external system acquired information.Specifically, recently, provide have communication equipment for collecting detection (probe) vehicle of the driving information of vehicle.Communication equipment in detection vehicle is always coupled with information centre so that information centre's real-time collecting and the driving information of analyzing from a plurality of detection vehicles.Then, information centre is sent to each vehicle by the information such as traffic congestion information and rainy information.

The information of being collected by detection vehicle comprises the behaviour in service of actual electric power consumption and drive route and the vehicle of this detection vehicle.This information is uploaded to information centre.Thereby the detection vehicle information data library storage in information centre is about the information of actual electric power consumption and the drive route of this detection vehicle and the behaviour in service of this detection vehicle.Be stored in actual electric power consumption data in information centre for calculating the electric power consumption amount of estimation.Specifically, the behaviour in service of the weight of the type such as vehicle, passenger's quantity, luggage and driving performance is uploaded to information centre.Then, when the behaviour in service of vehicle is identical with detection vehicle, the electric power consumption amount data in the navigator 5 downloaded stored Gai information centres in vehicle.Thereby navigator 5 is used the actual electric power consumption data of downloading from information centre to calculate the electric power consumption amount of estimating.Thereby equipment 5 is treated to the actual electric power consumption data of this detection vehicle the data of being prepared by the navigator 5 of vehicle.In this case, the actual electric power consumption data can Jiang Cong information centre obtaining is registered as the information being obtained by navigator 5.

When the behaviour in service of uploading from navigator 5 and detection vehicle information data, the behaviour in service of detection vehicle is inconsistent, information centre determine the behaviour in service upload from navigator 5 whether with detection vehicle information database the behaviour in service of detection vehicle similar.In the time of the behaviour in service of the similar detection vehicle of behaviour in service with uploading from navigator 5 is stored in detection vehicle information database, navigator 5 is downloaded the actual electric power consumption data of this detection vehicle from detection vehicle information database.Navigator 5 is calculated the electric power consumption amount of estimation by making compensation factor be multiplied by the actual electric power consumption of downloading from information centre.Compensation factor is corresponding with the difference between vehicle and detection vehicle.Specifically, when the behaviour in service of vehicle and the behaviour in service of detection vehicle equate substantially, by the actual electric power consumption of detection vehicle as the electric power consumption amount of estimating.When the behaviour in service of vehicle does not equate with the behaviour in service of detection vehicle substantially, the actual electric power consumption of detection vehicle is not directly used as to the electric power consumption amount of estimating.In this case, by making the actual electric power consumption that compensation factor is multiplied by detection vehicle obtain the electric power consumption amount of estimating.Even when detection vehicle is gasoline-powered vehicles and diesel powered vehicle rather than motor vehicle and motor vehicle driven by mixed power, the electric power consumption amount of the estimation of plug-in vehicles is estimated in the actual energy consumption of this gasoline-powered vehicles and diesel powered vehicle of can take as basis.

By as follows for calculating the example shown of general equation of electric power consumption amount of estimation of plug-in vehicles.

（EST?E?P?CON?AMOUNT）=（ACT?E?PCON?AMOUNT?OF?PROBE?V）*（VEH?CH?X）*（LOAD?FACT?Y）*（DRI?CH?Z）

Here, the electric power consumption amount that term " EST E P CON AMOUNT " representative is estimated, term " ACT E P CON AMOUNT OF PROBE V " represents the actual electric power consumption of detection vehicle, term " VEH CH X " represents vehicle feature factor X, term " LOAD FACT Y " represents on-load factor Y, and term " DRI CH Z " represents driving performance factor Z.

When the type of vehicle equals the type of detection vehicle, vehicle feature factor X is 1.When the weight of vehicle is less than the weight of detection vehicle, vehicle feature factor X is arranged in the scope between 0 and 1.When the weight of vehicle is greater than the weight of detection vehicle, vehicle feature factor X is set to be greater than 1.

When the passenger in vehicle and the weight of luggage are less than the weight of passenger and luggage in detection vehicle, on-load factor Y is arranged in the scope between 0 and 1.When the passenger in vehicle and the weight of luggage are greater than the weight of passenger and luggage in detection vehicle, on-load factor Y is set to be greater than 1.

When the acceleration of vehicle and the number of repetition of deceleration are less than the acceleration of detection vehicle and the number of repetition of deceleration, driving performance factor Z is arranged in the scope between 0 and 1.When the acceleration of vehicle and the number of repetition of deceleration are greater than the acceleration of detection vehicle and the number of repetition of deceleration, driving performance factor Z is set to be greater than 1.In addition, when the number of repetition turning in the operation of vehicle is less than the number of repetition turning in the operation of detection vehicle, driving performance factor Z is arranged in the scope between 0 and 1.When the number of repetition turning in the operation of vehicle is greater than the number of repetition turning in the operation of detection vehicle, driving performance factor Z is set to be greater than 1.Here, suppose that steering vehicle and detection vehicle travel on identical road, take and as basis, determine driving performance by the acceleration of the acquisitions such as onboard sensor and deceleration mode and/or deflecting roller work angle pattern.

When the information of having downloaded about detection vehicle, above-mentioned correction can be carried out by navigator 5.Alternatively, navigator 5 is uploaded the information of the weight about vehicle, the passengers quantity in vehicle, the weight of luggage etc. to information centre.Then, information centre's calculation correction factor, and navigator 5 is downloaded correction factor or result of calculation from information centre.Thereby equipment 5 calculates the electric power consumption amount of estimating.

Vehicle along search route running time, with reference to Fig. 8, explain for calculating the computational methods of the electric power consumption amount of estimation.At vehicle during once along the route running of search, step D1 be judged as "Yes" time, in step D3 by making safety factor and actual electric power consumption now multiply each other to obtain the electric power consumption amount of estimation.In this case, for calculating the search pattern of the electric power consumption amount of estimation, can equal the whole route from starting point to destination that vehicle once travelled.Alternatively, for calculating the part that the search pattern of the electric power consumption amount of estimation can be the route from starting point to destination that once travelled of vehicle.At vehicle during also not along the route running of search, step D1 be judged as "No" time, in step D2, equipment 5 or information centre determine that whether detection vehicle data in detection vehicle information database are for calculating the electric power consumption amount of estimation.Specifically, equipment 5 or information centre determine whether the behaviour in service of vehicle is substantially equal to or is similar to the behaviour in service of detection vehicle, and when detection vehicle travels in same routes, the actual electric power consumption data of detection vehicle is registered in database.When the actual electric power consumption amount data of registration, step D2 be judged as "Yes" time, in step D4, by the actual electric power consumption of the correction factor corresponding with behaviour in service and detection vehicle is multiplied each other, calculate the electric power consumption amount of estimation.

Unregistered with and during the corresponding actual electric power consumption of search pattern same routes, step D2 be judged as "No" time, similar with the first embodiment, in step D5, take the angle of inclination of this road of obtaining from map datum and the electric power consumption amount of calculating estimation along the traffic lights quantity of this road as basis.It is that next charging operation plan is prepared on basis that navigator 5 be take the electric power consumption amount of estimating.

In the present embodiment, navigator 5 take by travel with search pattern same routes on the actual electric power consumption data collected of detection vehicle be that basis obtains the electric power consumption amount of estimating.It is that next charging operation plan is prepared on basis that equipment 5 be take the electric power consumption amount of estimating.Thereby, improved the estimation accuracy of the electric power consumption amount of estimating.Thereby, adequate preparation for driving the amount of electrical power that is filled with of plug-in vehicles, so that prevented from being filled with the deficiency of amount of electrical power.Thereby equipment 5 has prevented that use commercial electrical power source rather than solar energy photovoltic power system from carrying out overcharge definitely.

In addition,, when vehicle once travelled on search pattern, the equipment 5 use now electric power consumption amount of reality are calculated the electric power consumption amount of estimation.Thereby, more improved the estimation accuracy of the calculating of the electric power consumption amount of estimating.

In the time of in database at a plurality of detection vehicle information data storings behaviour in service with vehicle is similar or that equate in information centre, can use the mean value of a plurality of detection vehicle information datas as detection vehicle information data.

(the 4th embodiment)

With reference to Fig. 9 and Figure 10, explain the 4th embodiment.In the first embodiment, owing to not being fine at weather traffic bad, so user must earlier start steering vehicle so that late than the time departure of scheduling.In this case, may not complete the charging of battery 4.Thereby, may battery 4 be charged the position outside room.Thereby charging scheduling may be subject to user's unexpected behavioral implications.In the present embodiment, consider user behavior, revised charging scheduling.

Fig. 9 shows the block diagram of the whole system of charge controller in plug-in vehicles.The charge controller 2 that provides information acquisition element and residual electricity quantity of power to determine element also comprises that commercial advertisement information acquisition element 9, user wake information acquisition element 10 up, individual schedule information obtains element 11 and year scheduling and traffic congestion information acquisition element 12.Navigator 5 can be by the gain-of-function following information in equipment 5.

(1) Weather information hourly

(2) the electric light information in user family

(3) advertising message of commercial facility

(4) user's scheduling adjustment information

(5) opening of celebrating such as school and the annual event information of closing

(6) such as the emergency information of traffic accident

Via the Internet, VICS(vehicle information communicating system, registered trade name) etc. from a certain server, obtain the advertising message of Weather information hourly, commercial facility and such as the emergency information of traffic accident.From the household safe server of family, obtain the electric light information user family.From the information terminal of the communication function of having of being carried by user such as bluetooth (registered trade name), obtain user's scheduling adjustment information.The annual event information of the opening of celebrating such as school and closing is stored in individual database in advance.

Next, will be explained in the modification of charging and dispatching when equipment 5 obtains above-mentioned information.

Figure 10 shows the flow chart that the modification in charge controller 2 is processed.

Charge controller 2 determines in step e 1 whether equipment 5 obtains Weather information hourly by the Internet.In addition, controller 2 determines in step e 4 whether equipment 5 obtains user and wake information up.Controller 2 determines in step e 7 whether equipment 5 obtains the advertising message of commercial facility.Controller 2 determines in step e 11 whether equipment 5 obtains individual schedule information.Controller 2 determines in step e 14 whether equipment 5 obtains event information from individual database.

(1) the charging scheduling of considering Weather information per hour is revised

When equipment 5 obtains current weather information through the Internet from weather forecast server with the predetermined space such as every several hours, step e 1 be judged as "Yes" time, proceed to step e 2.In step e 2, controller 2 determine whether equipment 5 receives weather forecast so that weather will be at next in it working day before commuting time section, within least three hours, rain or poorer than rainy.When weather forecast is said weather by variation, in step e 2 be judged as "Yes" time, proceed to step e 3.In step e 3, controller 2 reset charging scheduling so that make when user's time departure accelerates in the past charge the deadline accelerate (shift to an earlier date) user's input time or accelerating time on average.In this case, in step e 19, revise charging scheduling with the compensation accelerating time.In this case, in the situation that consider that the electrical power cost of the time period at night of business power source forms while charging scheduling, preferably ignores the time period at night of business power source and battery 4 is carried out to quick charge.

(2) the charging scheduling of considering the information of waking up is revised

On weekdays, user almost has identical behavior pattern.Yet, because a certain event occurs, according to average wakeup time, change wakeup time.In this case, according to average time departure, change time departure.Equipment 5 from domestic safety server obtain such as user's wakeup time wake information up time, step e 4 be judged as "Yes" time, proceed to step e 5.Here, because domestic safety server monitors the electric power consumption of family ammeter and the lamp of family, equipment 5 or server with the electric consumption (that is, the variation of ammeter) and for detection of the testing result of the optical pickocff of the opening operation of lamp for detecting user's wakeup time in basis.In step e 5, the time departure of controller estimating user is more Zao or more late than common time departure.In this case, take according to the statistical information of the time in past of the wakeup time of user's past behavior pattern acquisition is the estimation that the time departure after user wakes up and prepares a few minutes or several hours for going out is carried out on basis.Thereby, in step e 6, according to the time departure of estimating, shift to an earlier date or postpone the charging deadline of scheduling.In this case, when the time departure of scheduling shifts to an earlier date, make battery 4 quick charges.When the time departure of scheduling postpones, extend the charging interval of solar energy photovoltic power system so that the utilization factor of solar energy photovoltic power system increases.Then, in step e 19, according to the charging deadline of the time departure of estimating or scheduling, revise (replacement) charging and dispatch.

(3) the charging scheduling of considering advertising message is revised

In extensive electrical equipment market, plan to carry out sales promotion on opening is celebrated, or the special promotion of extensive supermarket plan such as Tuesdays is during day, the opening time or promotion period, the road amount around this extensive electrical equipment market or extensive supermarket is large.Thereby, when equipment 5 obtains the advertising message of commercial facility from information server, step e 7 be judged as "Yes" time, proceed to step e 8.In step e 8, controller determines whether to be provided with in advance destination.When being provided with destination in advance, step e 8 be judged as "Yes" time, equipment 5 in step e 9, take map datum and the address of the commercial facility that obtains from advertising message as the large region of the basic forecast volume of traffic and the large time of the volume of traffic.In this case, the discount information of take in sales promotion information such as the phrase of " 20% price reduction " is basis, and the discount degree of sales promotion of take is basic, the size of the part that equipment 5 prognosis traffic volumes are large (region).Take in sales promotion information promotion period be basis, the time that prognosis traffic volume is large.Consider large area and the time of the volume of traffic, because the volume of traffic causes greatly the running time from current location to destination, increase.Thereby, in step e 10, according to running time and the charging deadline of forward scheduling.Then, in step e 19, according to the charging deadline of running time or scheduling, revise (replacement) charging and dispatch.In this case, preferably, because the volume of traffic causes greatly electric power consumption Efficiency Decreasing, necessary amount of electrical power is set to larger.

(4) the charging scheduling of considering individual scheduler is revised

At equipment 5, obtain lastest imformations, by user, be carried to the scheduling adjustment information in the data dispatching of the mobile device with communication function in vehicle, time, step e 11 be judged as "Yes" time, proceed to step e 12.In step e 12, at user's data dispatching, have the used time, for example data dispatching be illustrated in the morning set of time earlier during meeting, in step D12, predict time departure.Then, in step e 13, according to the charging deadline of conferencing information forward scheduling.Then, in step e 19, according to the charging deadline of conferencing information or scheduling, revise (replacement) charging and dispatch.

(5) consider the charging scheduling modification from the event information of DB

New employee's quantity that the Ji Tianneidao company starting from annual first day travels frequently increases.In this case, company's road around and the volume of traffic increase of crossroad.In summer vacation, starting student's quantity that Shi Dao school travels frequently is substantially zero.In this case, school's road around and the volume of traffic reduction of crossroad.Thereby every year, although the date of event can be different, the volume of traffic of road can change according to recurrent event.In database, registration causes the event that the volume of traffic is large.At equipment 5, obtain the event information and this event that are stored in database and remain on ensuing drivings during day, step e 14 be judged as "Yes" time, proceed to step e 15.In step e 15, because the student who travels frequently may cause the volume of traffic large, be therefore arranged on the existence of the camera detection student on vehicle when event information relates to school.In this case, conventionally very large in school of schoolday road Traffic Volume around.Bu Shi schoolday hourly capacity reduces.In step e 16, controller determines whether it is schoolday.During Bu Shi schoolday, step e 16 be judged as "No" time, in step e 17, the time that prognosis traffic volume is large.In step e 18, according to the charging deadline of event information delay dispatching.Then, in step e 19, according to the charging deadline of event information or scheduling, revise (replacement) charging and dispatch.

Here, because student wears identical school uniform, the video capture of camera of take can easily distinguish as basis whether individual is student.In this case, preferably according to season in switching judging pattern between summer school uniform pattern and winter school uniform pattern.Can change according to the quantity of vacation the end of vacation in spring.Yet, suppose that school, on first Monday, determines schoolday.

When the deadline is charged in the behavior of driving Japan-China weather and/or user according to the next one in advance, if automatically quick charge of battery can damage as the lithium ion battery of the battery of plug-in vehicles the life-span of battery is reduced.Thereby, only the residual electricity quantity of power in battery 4 battery capacity 20% and 80% between scope in time just battery 4 is carried out to quick charge.Here, by the scope definition between 20% and 80%, be quick charge scope.In the time of outside the scope of residual electricity quantity of power in battery 4 between 20% and 80%, battery 4 is charged normal.Thereby, control suitably charging rate, so that can minimize electrical power cost, and improve in addition the life-span of battery 4.

Although not shown in Figure 10, while receiving the emergency information such as traffic accident information from transport information at equipment 5, can reset charging scheduling so that the deadline of charging in advance avoid the impact of traffic congestion.

Because this user when user leaves vehicle supposes that next driving day is the rainy day, so this user can reset to the scheduling time departure of next one driving day in advance.In this case, if equipment 5 receives nearest Weather information, and weather forecast at the time departure of scheduling, from the rainy day, change to cloudy or fine, the time departure that user can delay dispatching.Thereby the charging scheduling of can again resetting is so that change to normal commuting time by the time departure of charging deadline or scheduling.Thereby, until before the time departure of scheduling, improved the utilization factor of solar energy photovoltic power system.In addition,, due to the traffic congestion that does not have to cause because of the rainy day, vehicle arrives destination in the time of advent of expection.

In the present embodiment, after forming charging scheduling, the charging deadline in hypothesis charging scheduling, while preferably changing from the original charging deadline, is revised charging scheduling.Thereby, battery 4 is reliably charged.

Even when charging in advance the deadline according to the modification of charging scheduling, due to until battery 4 is carried out to quick charge before the charging deadline, therefore battery 4 is reliably charged.In this case, due to battery just quick charge when only the residual electricity quantity of power in battery 4 is suitable, thereby, even when battery 4 is carried out to quick charge, also can make the damage of battery 4 minimize.

(modification)

In the above-described embodiments, plug-in vehicles is plug-in hybrid vehicle.Alternatively, plug-in vehicles can be plug-in type electromagnetic motor-car.In this case, because vehicle when battery 4 is discharged completely can not move, therefore safety factor need to be set the in the situation that of charging process greatly.

Replace the charge controller in navigator 5, can be as the ETC(E-payment system of charge member) equipment is arranged on vehicle.ETC equipment is from navigator 5 acquired informations.

Navigator 5 monitors Weather information.When Weather information changes, can revise charging operation plan.Alternatively, when Weather information changes, user can revise charging scheduling.When equipment 5 obtains traffic congestion information, equipment 5 can arrange the time started of scheduling early, and in addition, equipment 5 can change charging scheduling according to the time started early.
