Description

  The present invention relates to a technical field of a solar information utilization apparatus in order to effectively use, for example, information related to sunlight in a mobile body equipped with a solar cell.

  As this type of device, a device that uses sunlight irradiation information for route search has been proposed (for example, see Patent Document 1). According to the vehicular route guidance device disclosed in Patent Document 1, when searching for a route to the destination using the map data for search stored in the map database, the terminal voltage of the battery is lowered. Is guided to a route with a large amount of sunlight irradiated to a vehicle or a parking lot with a large amount of sunlight irradiated. For this reason, it is supposed that the electric power generation by the solar cell mounted in a vehicle can be performed efficiently.

JP 2000-353295 A JP 2006-327247 A JP 2008-172959 A JP 2007-320352 A JP 2000-253504 A

  According to the device disclosed in Patent Document 1, when a plurality of destination candidates can be taken in the route search, it is possible to select the route with the largest amount of sunlight irradiation from among them and guide the vehicle. is there.

  However, the irradiation amount of sunlight referred to when selecting the destination is calculated based on various kinds of data given in advance (for example, according to Patent Document 1, an object near the destination, an estimated arrival time, etc.). It is grasped alternatively by the sunshine cost as an estimated value. That is, in the apparatus disclosed in Patent Document 1, no consideration is given to the future amount of sunlight irradiation at the selected destination. The sunshine cost is an estimated value as described above, and does not necessarily reflect the actual amount of sunlight irradiated for each destination.

  Therefore, in the apparatus disclosed in Patent Document 1, in terms of practical operation, for example, as a result of parking, there is a possibility of dissatisfaction such that the amount of sunlight irradiated cannot be obtained as expected.

  In the devices disclosed in Patent Documents 2 and 3, the future power generation amount can be predicted. However, the device drive conditions after arrival at the destination are only optimized, Regardless of accuracy, it is unlikely to be a fundamental solution to this type of problem.

  Furthermore, in the devices disclosed in Patent Documents 4 and 5, the device from the viewpoint of effectively using sunlight is insufficient compared to the above documents.

  As described above, in the related art including the devices disclosed in Patent Documents 1 to 5, when a moving body can take a plurality of destinations, a destination that can optimally receive sunlight can be selected. There is a technical problem that it is difficult.

  This invention is made | formed in view of such a problem, and it aims at providing the sunlight information utilization apparatus which can implement | achieve the proposal of an optimal destination from a viewpoint of the effective utilization of sunlight. .

  In order to solve the above-described problems, the first sunlight information utilization apparatus according to the present invention can construct a sunlight information utilization system together with a database capable of storing transmitted data and can generate power using sunlight. A solar information utilization apparatus that can be mounted on a mobile body equipped with a power generation means, and that receives the daily information related to the daily life of the mobile body, and corresponds to the obtained daily information. Condition information acquisition means for acquiring condition information relating to information acquisition conditions, and transmission for transmitting sunlight information in which the acquired daily information and the acquired condition information are associated with each other as the data to the database Means.

  The first sunlight information utilization apparatus according to the present invention can be mounted on various mobile objects, and uses the sunlight information described later, which constructs a sunlight information utilization system together with the database according to the present invention. It is a device.

  Here, the database according to the present invention is wired or wirelessly connected to various storage media or storage elements that can take various aspects depending on the apparatus configuration of the database, for example, which can be fixed inside the database or can be appropriately switched. It is possible to store (that is, store) data to be transmitted regardless of whether or not the stored information can be read out appropriately according to an appropriate request. The database according to the present invention includes, for example, various information recording devices such as an installation type, a built-in type or a portable type HDD (Hard Disk Drive), a DVD drive, a BD (Blu-ray Disk) drive, a CD drive, or the like. An information recording system in which various control devices such as a microcomputer, a personal computer, or a workstation are added to the device may be used.

  The database according to the present invention may be built in the first sunlight information utilization apparatus according to the present invention, or may be connected constantly or appropriately. Alternatively, the database according to the present invention and the first solar information utilization apparatus are accommodated in various networks such as a wired LAN, a wireless LAN, a mobile communication network, or the Internet, and are connected via the network. May be. In any case, the first sunlight information utilization apparatus can transmit sunlight information described later to this database, and can preferably acquire sunlight information from this database. Note that the acquired sunlight information may be transmitted to this database by another sunlight information utilization apparatus that constructs the sunlight information utilization system according to the present invention. That is, this sunlight information may be information shared between devices participating in the sunlight information utilization system.

  The moving body according to the present invention is a concept encompassing movable objects, and as a preferred form, means a human or various vehicles that can be moved using various moving means. The aspect is not limited in any way. The first sunlight information utilization device can be mounted on a mobile body as such a concept, but “installable” may be mounted as necessary or may be mounted constantly. , Meaning that it may be permanently installed. In other words, the first solar information utilization apparatus may be selected as appropriate even if the installation location is fixed. In the latter case, the first solar information utilization apparatus changes each time depending on the intention or intention of the owner or user. It may have portability and incidental properties, etc., as appropriate, enabling installation at a variable installation location. For example, the first solar information utilization device is a mobile phone, a personal digital assistance (PDA), a notebook personal computer, or various mobile terminal devices or portable terminals including a car-mounted or portable car navigation device. Each may be a part of the device. In this moving body, for example, a solar cell, a solar cell panel in which a plurality of the solar cells are connected, or a solar power generation device or the like provided with a solar cell module to which various electric circuits are attached. It is equipped with power generation means that can adopt.

  According to the 1st sunlight information utilization apparatus which concerns on this invention, the sunlight information regarding the sunlight of a mobile body is acquired by the sunlight information acquisition means at the time of the operation | movement. Here, "sunlight" means the sunlight irradiation state, and the sunlight information is information that can represent this sunlight irradiation state under various modes.

  For example, the daily information includes various physical quantities, control quantities, index values, numerical values, etc. that can correlate in a one-to-one, one-to-many, many-to-one, or many-to-many with the degree of sunlight, that is, the degree of sunlight irradiation. Also good. Further, the sunlight information may be the amount of sunlight irradiated, the temperature inside or outside the moving body or the temperature within a certain period, the average temperature or the amount of temperature change. Alternatively, the daily information may be an actual power generation amount or power generation efficiency in the power generation means.

  On the other hand, according to the 1st sunlight information utilization apparatus which concerns on this invention, the condition information regarding the acquisition condition of the daily information corresponding to the acquired daily information is acquired by the condition information acquisition means at the time of the operation. Here, the “acquisition condition” is a concept that includes various conditions at the time of acquiring the daily information in which a correlation with the daily intensity is recognized experimentally, empirically, theoretically, or based on a simulation or the like.

  For example, the acquisition condition may be information related to the position of the moving object at the acquisition time of the daily information, the acquisition period, or the period targeted by the acquired daily information. In this case, for example, a position on a two-dimensional plane composed of latitude and longitude obtained via various positioning systems such as GPS (Global Positioning System), a position on a three-dimensional space composed of latitude, longitude and altitude are prepared in advance. It may be information such as a coordinate position defined on map data or a position defined by an address or the like. Moreover, the information regarding the existence area | region or existence space of a moving body prescribed | regulated including the position of this kind of moving body on two-dimensional or three-dimensional space may be sufficient.

  Alternatively, the information on the position of the moving body is information that defines a relatively large space dedicated to parking, generally called “parking lot” or “parking space” (for example, the address of a parking lot or parking space). And information that defines a relatively limited space such as a parking lot or a section of a vehicle in the parking space (for example, “△ th from the left side and the front toward the entrance of the parking lot” In addition, information on the exact position in such a relatively limited space (for example, exact positioning and parking direction in a certain parking area) Also good. Or, it is not limited to a position, area or space prepared exclusively for this kind of parking, for example, in a public road or private facility where parking is permitted under the regulations, for example, on a general road permitted to park according to regulations. It may be the position, area or space (for example, “in front of the △ Δ ward office entrance”).

  From the viewpoint of effective use of sunlight information, the “acquisition condition” according to the present invention is preferably information including at least information on the position of this type of moving body.

  In addition, the acquisition condition may be a weather condition that corresponds to the acquisition point of the daily information, the acquisition period, or the period covered by the acquired daily information. Here, the “climatic meteorological condition” means various conditions derived from time or weather that can affect the above-described irradiation state of sunlight (that is, sunlight) to an extent that cannot be ignored in practice.

  For example, the meteorological weather condition is a parking condition that specifies the time period such as the length of the parking period of the moving object (the time range in which the moving object has been parked at one parking position), and the parking period corresponding to one day's information. Start time and parking end time (Note that the start time and the parking end time are not limited to the time when the moving body actually stops at the parking position and the time when the vehicle actually starts from the parking position. That is, the control start defined based on a predetermined criterion. And a time condition such as an end time). Also, what time zone (for example, a category such as morning, morning, noon, afternoon, evening, night or midnight, or a control time zone defined by a reference time) corresponds to the parking period. It may be a belt condition. Furthermore, it may be a calendar condition such as date, season or energy saving, and a weather condition such as weather or weather.

  According to the 1st sunlight information utilization apparatus which concerns on this invention, the sunlight information by which these sunrays information and condition information are mutually linked | related is transmitted with respect to the database mentioned above by the transmission means. In addition, the first solar information utilization device does not necessarily have to include means for acquiring solar information transmitted from the other solar information utilization device in the past from this database. The first sunlight information utilization apparatus can perform bidirectional data communication with this database.

  The “sunlight information” according to the present invention is information in which daily information and condition information as the above-described concept are associated with each other. For example, the solar power information is “the amount of power generated by solar cells when parked for 1 hour in the parking lot of the beach A on a clear day in August”, “from 4 pm to 6 pm in cloudy January” "Balance between the amount of power generated and discharged by a solar cell when parked in D Hall in C City, B Prefecture" or "H route on foot from F station to G station during summer day in fine weather It is possible to have various practical aspects that can be obtained by appropriately combining daily information and condition information, such as “irradiation amount of sunlight”, or that can be obtained through appropriate numerical operation processing or logical operation processing based on these. Information.

  Therefore, for those who use sunlight information, for example, “How much power can be obtained when parking for xx hours in the parking lot?”, “▲▲ In parking lot and □□ parking lot, X ▲ How much power generation will differ if you stay for hours? ”,“ ■■ I want to park in the parking lot, what is the appropriate parking area and parking direction? ” “Which place is the most exposed to sunlight over several hours?”, Etc. “Relevant, accurate, or optimal for requests, requests, or requests that can change in any way depending on the individual circumstances of the user It is information that can give a correct solution.

  Here, since the transmitted sunlight information is accumulated in the database, the type and quantity of the sunlight information accumulated in the database increases according to the usage frequency of the first sunlight information utilization device, The reliability of solar information is improved. Moreover, when a sunlight information utilization system is constructed | assembled by several 1st sunlight information utilization apparatuses and a database, the tendency and wrinkles for every owner of a 1st sunlight information utilization apparatus are offset, and the sun Since the update frequency of optical information is improved, the reliability and usefulness of sunlight information can be dramatically improved.

  Thus, according to the 1st sunlight information utilization apparatus which concerns on this invention, even if a database transmits / receives sunlight information only between one sunlight information utilization apparatus, many sunlight information Even when the sunlight information is transmitted to and received from the utilization device, it is possible to accumulate the sunlight information based on the daily information as the information accompanying the actual measurement and the condition information regarding the acquisition conditions. Therefore, it is possible to propose an optimum destination from the viewpoint of effective use of sunlight.

  Supplementally, how much the irradiation state of sunlight in the route to the parking position is taken into account, it is unclear about the irradiation state of sunlight over the future parking period at the parking position. Therefore, when the moving body can be guided to a parking position where sunlight can be effectively used accidentally, guiding the moving body to a parking position where sunlight can be used effectively effectively is not possible. Almost impossible. Moreover, when the irradiation state of sunlight was estimated considering how much the building and the building near the parking position were taken into consideration, the irradiation state of sunlight without supporting the actual measurement data is clearly inferior in its credibility. It is.

  In addition, the means for generating or constructing the sunlight information based on the sunlight information and the condition information may be provided by other means such as a transmission means, for example. The solar light information utilization apparatus may be included, or may be another apparatus different from the first solar light information utilization apparatus.

  In one aspect of the first solar information utilization apparatus according to the present invention, the daily information acquisition unit acquires at least one of the power generation amount and the power generation efficiency of the power generation unit as the daily information.

  The amount of power generated by the power generation means and / or the power generation efficiency are appropriate values as the daily information according to the present invention because they have a high correlation with the degree of daily light.

  In another aspect of the first solar light information utilization apparatus according to the present invention, the condition information acquisition unit acquires, as the condition information, at least position information of the mobile body corresponding to the acquired sun light information.

  As described above, since the information on the position of the moving object is information that defines what kind of place the amount of sunlight suggested by the amount of sunlight corresponds to the amount of sunlight, the effectiveness of the sunlight information is improved. Information that can be largely defined. Therefore, it is suitable as the condition information according to the present invention. In addition, the practical aspect of the “position information” according to this aspect may include various practical aspects related to the information related to the position of the moving body described above.

  In another aspect of the first solar light information utilization apparatus according to the present invention, the moving body includes a driven device that is driven by the generated power of the power generation means, and the sunlight information acquisition means is the sunlight information. The power required for driving the driven device is acquired.

  According to this aspect, the mobile body is driven by consuming the generated power as the power generated by the power generation means using sunlight, for example, various electric drives such as an air conditioner, a cooling device, or a ventilator. A type driven device is provided.

  In some cases, the sunlight of the mobile body may cause a decrease in comfort of the mobile body space. For example, even if the sunlight is good, the mobile body space may become hot or humid to such an extent that it can generally be determined to be uncomfortable. Alternatively, the air in the mobile body space may become stagnant or dirty to the extent that it can generally be determined as uncomfortable. From the point of view of practical use of mobile objects, it is often the case that the judgment that this kind of unpleasant phenomenon should be avoided should be established.

  On the other hand, this type of driven device operates by consuming the power generated by the power generation means, and is driven semi-automatically (for example, so that the room temperature is kept constant) during the parking period of the moving body. A device that can be made. Therefore, the electric power (that is, power consumption) required for driving the driven device can have a unique relationship with the sunlight in the mobile body, as well as the power generation amount and power generation efficiency of the power generation means. That is, depending on the operating state of this type of driven device, the generated power itself does not necessarily have a unique relationship with the power stored as effective power in the battery or various power storage means.

  Here, according to this aspect, the sunlight information is acquired as information including at least the electric power required for driving the driven device. Accordingly, the daily information is acquired with more practical meaning. For example, if the generated power is 1 kW and the power consumption of the driven device is 0.8 kW, the effective daily degree is equivalent to 0.2 kW. On the other hand, if the generated power is 0.6 kW and the consumed power is 0.2 kW, the effective daily rate is equivalent to 0.4 kW, and the practical operation from the viewpoint of the power balance is the latter. It can be determined that this is the preferred day.

  In this aspect, the driven device may be temperature adjusting means for adjusting the temperature of the moving body.

  When this type of temperature adjustment means is provided as the driven device, for example, the temperature inside the moving body can be suitably maintained at a desired temperature or a preset temperature during the parking period. It is remarkably effective in a specific period in which the temperature inside and outside the moving body tends to be excessively high or low, such as summer or winter.

  In order to solve the above-described problem, the second sunlight information utilization device according to the present invention can be mounted on a moving body together with a display device capable of displaying information, and determines a parking position candidate of the moving body. The solar light information corresponding to the determined candidate is determined from the solar light information in which the determining means, the daily light information relating to the daily life of the mobile body, and the condition information relating to the conditions for obtaining the daily light information are associated with each other. Sunlight information acquiring means to be acquired, and control means for controlling the display device so that display information corresponding to the acquired sunlight information is displayed as the information.

  The second sunlight information utilization apparatus according to the present invention can display various types of information such as various types of information such as image information, audio information, or video information (that is, display is not necessarily limited to visual appeal). It is configured to be mountable on a moving body together with various display devices such as a display device and a speaker device. Note that the second solar information utilization device and the first solar information utilization device are basically common in terms and components used in the description, and the first (or second) As long as there is no notice in particular about the part described in describing a sunlight information utilization apparatus, it is assumed that it is applicable similarly to the 2nd (or 1st) sunlight information utilization apparatus.

  According to the 2nd sunlight information utilization apparatus which concerns on this invention, the candidate of the parking position of a moving body is determined by the determination means. The “parking position candidate” means, for example, one or a plurality of parking positions selected from a variety of conditions prepared automatically or artificially. To do. Note that the term “parking” does not limit that the moving body is a “vehicle”.

  Here, “determination” related to the determination means means that a candidate for a parking position is selected from among options set in advance or prepared each time, or a candidate for a parking position selected externally. It is a concept including simply acquiring as data. That is, the parking position selection process itself may be performed inside or outside the second sunlight information utilization apparatus.

  For example, the second solar information utilization apparatus is accommodated in various networks such as various wide-area networks such as the Internet and limited networks such as LAN and WAN together with server apparatuses and the like (which may be the aforementioned database). In this case, the configuration may be such that the parking position candidate is determined on the server device side and provided to the second sunlight information utilization device via the network. In addition, when the second sunlight information utilization device adopts a device form similar to a car navigation device or adopts a device form that can use the car navigation device, such a parking position candidate is a car navigation device candidate. It may be determined as an action.

  According to the second sunlight information utilization device, the sunlight information is acquired by the sunlight information acquisition means as information in which the above-mentioned sun light information and the condition information are associated with each other. At this time, the sunlight information acquisition means may acquire the sunlight information from the inside of the second sunlight information utilization apparatus or may be acquired from the outside. Or both may be possible.

  For example, when the second sunlight information utilization apparatus is accommodated in various networks together with the above-described database, the sunlight information accumulated in this kind of database may be acquired. In addition, if this database is provided in the second sunlight information utilization device with various forms such as built-in or externally attached, the sunlight information may be acquired from the internal or externally attached database. . Alternatively, the above-described daily information acquisition means, condition information acquisition means, and the like may be appropriately provided in the second sunlight information utilization device. In such a case, the second sunlight information utilization device is You may generate | occur | produce the sunlight information of a seed | species suitably.

  On the other hand, when the sunlight information is acquired, the display device is controlled by the control means so that the display information corresponding to the acquired sunlight information is displayed.

  Here, the correspondence relationship with the sunlight information in the “display information” is not particularly limited, and the acquired sunlight information itself may be used. It may be information that has been decorated or corrected to improve performance. For example, the display information may be visual information such as a list in which each of the parking position candidates is rearranged in descending order of the amount of sunlight, or may be incidentally displayed on the parking position candidates shown on the map image. It may be visual information obtained by quantifying or iconifying the amount of sunlight irradiated. It may also be voice information such as “I recommend is” or “I have the best power generation efficiency”, or a more specific parking location such as “Please park in the direction of”. It may be audio information related to the instruction.

  Thus, according to the 2nd sunlight information utilization apparatus which concerns on this invention, the user of the 2nd sunlight information utilization apparatus is the sunlight produced | generated with the actual measurement in the other mobile body in the past. By appropriately selecting and referring to information that the user needs at that time from the information, at least a part of the candidates for the parking position of the moving object (because sunlight information does not necessarily exist for all candidates) Can be evaluated. For this reason, the proposal of the optimal destination can be realized.

  In one aspect of the second sunlight information utilization device according to the present invention, the sunlight information utilization device is housed in a network together with a database capable of storing the sunlight information, and the sunlight information acquisition means is The sunlight information is acquired from the database via the network.

  According to this aspect, the sunlight information utilization apparatus is accommodated in the network together with the database, and the sunlight information is acquired from the database via the network. When the database is constructed on a network, the limitation on the data storage capacity of the database is relatively relaxed, so that a relatively large amount of sunlight information can be stored, which is useful in practice.

  In addition, the database constructed on the network in this way can transmit / receive sunlight information to / from other solar information utilization apparatuses accommodated in the network, and the network via the solar information utilization apparatus. This is remarkably beneficial in that a common benefit can be enjoyed by all the mobile units accommodated in the vehicle.

  In addition, the 2nd sunlight information utilization apparatus which concerns on this invention may be equipped with this kind of database. In this case, the sunlight information acquisition means can stably acquire sunlight information without being affected by the communication state of the network (communication speed, communication stability, etc.).

  In another aspect of the second solar light information utilization apparatus according to the present invention, the sun light information is information generated based on an irradiation state of solar light measured in the past.

  According to this aspect, since the sunlight information is generated based on the irradiation state of sunlight measured in the past, the reliability of the sunlight information is improved and the utility value is also improved. In particular, when the state of sunlight irradiation includes the power generation state (power generation amount, power generation efficiency, etc.) of various power generation means, the reliability and utility value are improved. Reliability and utility value are improved compared to the case without actual measurement.

  In another aspect of the second solar light information utilization apparatus according to the present invention, the solar light information utilization device further comprises evaluation means for evaluating the determined candidate based on the acquired solar light information and a predetermined evaluation criterion, The control means displays the evaluation result by the evaluation means as at least a part of the display information.

  According to this aspect, based on the sunlight information acquired by the evaluation means and a predetermined evaluation criterion (for example, priority, essential items, priority, weighting, etc. for performing the evaluation) Thus, since a certain evaluation can be given to the determined candidate, the burden on the user side is reduced, and the effective use of sunlight can be realized more easily.

In another aspect of the second solar light information utilization apparatus according to the present invention, the mobile body includes power generation means capable of generating power using sunlight. According to this aspect, the mobile body is, for example, a solar cell. In order to provide solar power generation means that can take the form of a solar power generation device including a cell, a solar battery panel in which a plurality of the solar battery cells are connected, or a solar battery module in which various electric circuits and the like are attached thereto. Optical information can be used effectively.

  In another aspect of the second solar information utilization apparatus according to the present invention, the mobile device further includes a determination unit that determines whether or not the owner of the mobile object has an intention to park the mobile object, The display information is displayed when it is determined that the owner has the intention to park.

  According to this aspect, since the display information can be displayed when the owner of the mobile object has the intention to park the mobile object, it is substantially equivalent to the owner (that is, the user of the solar light information utilization apparatus). It is possible to further improve convenience.

  In addition, the practical aspect in which the determination unit determines whether or not there is a parking intention is not limited in any way as long as the user's intention can be estimated with accuracy that does not cause a problem in practice. For example, the discriminating means (1) when a user tries to execute a parking lot search via a car navigation device, (2) when the user approaches a destination during route guidance by the car navigation device, or ( 3) When approaching the home, it may be determined that each owner has the parking position of the moving object at home.

  In another aspect of the second sunlight information utilization device according to the present invention, the display device can display the display information as image information, and the control means is responsive to the acquired sunlight information. The display mode of the determined candidate in the image information is changed.

  According to this aspect, display information is displayed as image information, and the image information is appropriately changed according to sunlight information. For example, the mode of this change is the amount of sunlight irradiation (may be the power generation amount or power generation efficiency of the power generation means, the vehicle interior temperature, etc.) when there are a plurality of parking position candidates. May be divided quantitatively, and image information corresponding to each candidate may be changed according to the division. Thus, by changing the image information flexibly, the appeal to the user can be further improved and the effective use of sunlight can be promoted.

<Operation of Embodiment>
Next, with reference to FIG. 5, a solar information accumulation process executed by the ECU 100 in the vehicle 10 </ b> A will be described as an operation of the present embodiment. FIG. 5 is a flowchart of the sunlight information accumulation process.

  In FIG. 5, ECU 100 determines whether or not parking of vehicle 10A has been completed (step S101).

  The determination processing according to step S101 is executed based on whether or not the IG off state has elapsed for a predetermined time (for example, 5 minutes) or longer. When the parking is not completed (step S101: NO), the ECU 100 repeatedly executes step S101 and controls the process to substantially stand by until the parking is completed.

  On the other hand, when parking is completed (step S101: YES), the ECU 100 starts monitoring the power generation state (step S102).

  Here, “monitoring of the power generation state” means continuous recording of the power generation amount of the solar panel 200 in the vehicle 10A. The ECU 100 time-integrates the power generation amount of the solar battery panel 200 that is periodically calculated, and grasps the total power generation amount during the period until the monitor ends.

  Simultaneously with the start of monitoring of the power generation information, the ECU 100 starts continuous recording of the vehicle interior temperature Tmp detected by the vehicle interior temperature sensor 600. Further, simultaneously with the start of monitoring of the power generation information, the ECU 100 starts integrating the power consumption of the ventilation device 500.

  These three types of index values (power generation amount, temperature, and power consumption) are all examples of “daily information” according to the present invention, and all are highly reliable index values that can be actually measured as actual phenomena.

  When monitoring of the power generation state is started, the ECU 100 determines whether or not the vehicle 10 has started (step S103). When the state where the vehicle is parked at one parking position without starting is continued (step S103: NO), the monitoring of the power generation information is continued, and step S103 is repeatedly executed.

  On the other hand, when vehicle 10A starts from the parking position (step S103: YES), ECU 100 ends the monitoring of the power generation state (step S104) and acquires sunlight information (step S105).

  Here, the solar light information will be described again. The solar light information is the amount of sunlight (the total solar cell panel 200 total) that is irradiated with sunlight in one parking period (here, the time elapsed from step S102 to step S104). Power generation amount, average temperature and temperature change amount, and total power consumption) and parking position of the vehicle 10A (here, latitude and longitude information about the parking position obtained by analyzing the GPS signal, obtained by referring to the map information DB 831) The parking position and the parking angle θv described later of the vehicle 10A), monitor start time (may be parking start time), monitor end time (may be parking end time), date and weather It is prescribed by the weather conditions such as, and the model name. Each of the parking position, the monitor start time, the monitor end time, and the weather weather condition is an example of “condition information” according to the present invention.

  When the sunlight information is acquired, the ECU 100 transmits the acquired sunlight information to the sunlight information DB 832 and the sunlight information DB 22A (step S106), and the process returns to step S101.

  The transmission of sunlight information to the sunlight information DB 832 means an electrical data recording process inside the vehicle 10A, and the transmission of sunlight information to the sunlight information DB 22A is data via the network 2. Means sending. The transmitted sunlight information is suitably stored in any database. Here, various types of information constituting the sunlight information are transmitted in a state of being associated with each other, and the transmission of the sunlight information is performed. The ECU 100 converts these into a set of data in advance. The transmission process may be performed after conversion.

  Here, with reference to FIG. 6, the parking angle θv of the vehicle 10A forming part of the sunlight information in step S105 will be described. FIG. 6 is a conceptual diagram of the parking angle θv.

  In FIG. 6, the parking angle θv is an angle formed by a virtual line segment extending in the front-rear direction of the vehicle 10 </ b> A (see the chain line in the figure) and a virtual line segment extending in the north-south direction (a broken line connecting S and N in the figure). It is. This parking angle θv has a considerable influence on the power generation amount of the solar cell panel 200.

  Next, the details of the sunlight information DB 832 and the sunlight information DB 22A (here, simply abbreviated as “solar information DB”) will be described with reference to FIG. FIG. 7 is a diagram conceptually showing the configuration of the sunlight information DB.

  In the sunlight information DB, date, time (monitor start time and monitor end time), latitude (latitude of parking position), longitude (mild parking position), parking angle θv, location (name of parking position), weather, Each data item of temperature (here, average temperature), temperature change amount, power generation amount, consumption amount (power consumption amount described above) and vehicle type is sequentially arranged in the horizontal direction, and these data item groups are arranged in the horizontal direction. However, it is the structure which makes one piece of sunlight information. In other words, the sunlight information DB adopts a configuration in which sunlight information is arranged in the vertical direction. In addition, the arrangement | sequence aspect of sunlight information to a vertical direction can be freely changed by operation of the touchscreen apparatus 860 etc., for example.

  In the sunlight information DB, the latitude and longitude of the parking position are defined so finely that, for example, the change in the parking position in one parking space can be represented. Here, the reason will be described with reference to FIG. FIG. 8 is a diagram for explaining the influence of the change in the parking position in one parking space on the power generation amount of the solar cell panel 200. FIG. In the figure, the same reference numerals are given to the same portions as those in the above-described drawings, and the description thereof will be omitted as appropriate.

  In FIG. 8, a broken line frame P represents a parking space P for one vehicle. When the vehicle is parked forward in order from the left side to the left front side of the parking space P (referred to as pattern A), forward parking is performed on the right back side. In this case, the case where the vehicle is reversely parked in the middle (referred to as pattern C) is shown.

  On the other hand, in FIG. 8, the time transition of the power generation amount of the solar cell panel 200 corresponding to each parking position and direction (in the figure, the time transition from 6:00 to 20:00) is shown below the conceptual diagram of each parking position. Is done. As shown in the figure, from the viewpoint of the power generation amount, the pattern A is the most stable and the power generation amount is large, and the pattern B is the most unstable and the power generation amount is small. Even in the same parking space, the amount of power generation can change in this way depending on the parking position, so the latitude and longitude that define the sunlight information can also distinguish the parking positions in these parking spaces. Are given relatively fine.

  As described above, according to the sunlight information utilization system 1 according to the first embodiment of the present invention, the storage device provided in each vehicle or the storage device constructed on the network 2 by the sunlight information accumulation process. Each time the vehicle parks at the parking position, the sunlight information is transmitted.

  For this reason, innumerable sunlight information can be accumulated in a relatively short time especially in the storage device constructed on the network 2.

  This storage device is capable of two-way communication with each vehicle at all times or through a process such as authentication or login, and the vehicle accommodated in the network 2 can be connected to the network 2. For example, the sunlight information can be referred to at any time, and can be used as a base for determining the parking position of the host vehicle.

  Therefore, in each vehicle, when parking the vehicle in the future, it is possible to accurately and easily determine a parking position where sunlight can be used most effectively.

  In addition, supplementally, the sunlight information according to the present embodiment gives meaningful information other than the determination of the parking position of the vehicle. For example, if a person is treated as a moving body, a person who is walking can also effectively use sunlight information by installing components corresponding to the ECU 100 and the sunlight information DB 832 in, for example, a mobile phone. In this case, for example, an effective solution can be provided even for a trivial request such as sunbathing or walking on a sidewalk with good sunlight.

  In the present embodiment, the sunlight information includes the in-vehicle temperature Tmp of the vehicle 10A and the power consumption of the ventilation device 500 in addition to the power generation amount of the solar battery panel 200. , More versatile and verified. In particular, the power consumption of the ventilation device 500 changes according to the driving state of the ventilation device 500 with the generated power of the solar cell panel 200 as an upper limit. Corresponds to large. That is, the power consumption of the ventilation device 500 constructs a part of the sunlight information, so that it is possible to evaluate the balance between the power generation amount of the solar cell panel 200 and the power consumption amount of the ventilation device 500. It becomes possible to evaluate the parking position more practically. Even if the power generation amount of the solar cell panel 200 is large, the power consumption of the ventilation device 500 is also large, which is not necessarily preferable from the viewpoint of charging the battery 300.

In addition, even if there is no network 2 and the server device 20 and each vehicle has a configuration in which each vehicle independently accumulates sunlight information in the storage device, there is no influence on the essential benefits enjoyed by this embodiment. Absent. In addition, in this way, when sunlight information can be accumulated in the own vehicle, there is no problem with the sunlight information accumulated in the own vehicle even if the communication state with the network 2 is poor. Since it can be used without any problem, it is preferable from the viewpoint of reliability.
Second Embodiment
Next, a parking lot setting process executed by the ECU 100 will be described as a second embodiment of the present invention with reference to FIG. FIG. 9 is a flowchart of the parking lot setting process. It is assumed that the system configuration according to the second embodiment is equivalent to the solar information utilization system 1 according to the first embodiment.

  In FIG. 9, the ECU 100 determines whether or not there is a parking lot search request (step S201). When there is no parking lot search request (step S201: NO), the ECU 100 repeatedly executes step S201 and controls the process to substantially stand by. The “parking lot search request” specifically refers to a case where the driver of the vehicle 10A indicates an intention to request a parking lot search by human operation via the touch panel device 860 of the car navigation device 800. Means an electric signal output from the touch panel device 860 or an electric signal transmitted from the car navigation ECU 810 that has analyzed the electric signal to the ECU 100.

  When there is a parking lot search request (step S201: YES), the ECU 100 controls the display control unit 830 via the car navigation ECU 810 to display a condition setting screen on the display 850 (step S202).

  Here, the details of the condition setting screen will be described with reference to FIG. FIG. 10 is a schematic diagram showing an example of the condition setting screen. In the figure, the same reference numerals are given to the same parts as those in the previous figures, and the description thereof is omitted as appropriate.

  In FIG. 10, when step S202 is executed, on the display screen of the display 850, along with information such as “Please select a search condition”, “Focus priority”, “Focus on distance” and “Focus on charging” are displayed. A search condition icon corresponding to the type of search condition is displayed.

  The charge emphasis icon is an icon that emphasizes as a search condition that the parking fee per hour is low. The distance emphasis icon is an icon that emphasizes as a search condition that the current distance from the position of the vehicle 10A is short. The charge emphasis icon is an icon that emphasizes as a search condition that the amount of charge of the battery 300 during the parking period is large. The large amount of charge of the battery 300 means that qualitatively, the amount of power generated by the solar cell panel 200 is large while the amount of power consumed by the ventilation device 500 is small.

  Below these search condition icons, a check box that allows the driver to make a selection operation via the touch panel device 860 is provided, and a check mark indicating that the driver has been selected is displayed in the check box selected by the driver. . FIG. 10 shows a state in which two types of search condition icons, focusing on charges and charging, are selected.

  On the other hand, a determination icon (arrow-line icon) is displayed at the lower right of the display screen of the display 850. The determination icon is an icon for confirming the selection of the driver. When the determination icon is selected, the display of the condition setting screen ends. In FIG. 10, the search condition icon is selected in this way, but it is also possible to operate the determination icon without selecting any search condition icon. In this case, the default search condition is unconditionally selected as the search condition for the parking lot. Note that the default search condition may be arbitrarily set.

  Returning to FIG. 9, when the display of the condition setting screen is terminated, the ECU 100 determines whether or not the conditions are set by the driver (step S <b> 203). When any search condition icon is selected and conditions are set (step S203: YES), the ECU 100 searches for a parking lot based on the set search conditions (step S204). On the other hand, when the search condition icon is not selected (step S203: NO), the ECU 100 searches for a parking lot based on the default search condition (step S209). The parking lot search process itself based on the search conditions can be applied with various known algorithms, and since the relevance to the present application is weak, detailed description thereof will be omitted here.

  When the search condition icon corresponding to “important importance” is selected as the search condition, the ECU 100 converts the sunlight information corresponding to the parking lot candidate determined with reference to the map information DB 831 into the sunlight. Obtained from the information DB 832 or the sunlight information DB 22A. As described above, the sunlight information stored in each sunlight information DB includes the power generation amount of the solar cell panel 200 and the power consumption amount of the ventilation device 500. Therefore, for example, for a parking lot candidate existing within a predetermined distance from the vehicle 10A, a candidate relatively suitable for charging the battery 300 can be selected before selection by the driver. That is, such processing of the ECU 100 is an example of the operation of the “evaluation means” according to the present invention.

  When the parking lot search process based on the set conditions is completed, ECU 100 controls display control unit 830 via car navigation ECU 810 to display a search result display screen on display 850 (step S205).

  Here, the details of the search result display screen will be described with reference to FIG. FIG. 11 is a schematic diagram showing an example of the search result display screen. In the figure, the same reference numerals are given to the same parts as those in the previous figures, and the description thereof is omitted as appropriate.

  In FIG. 11, when step S202 is executed, the search result of the parking lot is displayed on the display screen of the display 850 as a list. This list is configured to switch to the next list when the “next candidate” icon at the lower right of the screen is selected. FIG. 11 shows that “second parking lot” has been proposed as a parking lot that best satisfies the driver's request. Note that parking lot candidates included in the list can be selected via the touch panel device 860.

  Returning to FIG. 9, when the search result display screen is displayed, the ECU 100 determines whether one of the parking lot candidates displayed in the list has been selected (step S206). If no parking lot candidate has been selected (step S206: NO), the ECU 100 continues to display the search result display screen according to step S205.

  When a parking lot candidate is selected (step S206: YES), the ECU 100 determines whether or not the selected candidate may be set as a destination (step S207). At this time, the ECU 100 is displayed by linking to information such as “Would you like to set this parking lot as the destination?” That appears when a candidate parking lot is selected on the search result display screen, “OK” And “Cancel” software button is selected.

  That is, when “OK” is selected, the ECU 100 determines that the selected candidate is permitted to be set as the destination, and when “Cancel” is selected, the ECU 100 is selected. It is determined that setting a candidate as a destination is not permitted.

  If it is not permitted to set the selected candidate as the destination (step S207: NO), the ECU 100 returns the process to step S205 and displays the search result display screen again. On the other hand, when it is permitted to set the selected candidate as the destination (step S207: YES), the ECU 100 sets the selected parking lot candidate as the destination (step S208). When step S208 is executed, the process returns to step S201.

  Thus, according to the parking lot setting process according to the present embodiment, when the driver desires to search for a parking lot for parking the vehicle 10A, the search result is an example of the “display information” according to the present invention. The display screen is displayed. This search result display screen is based on the power generation amount of the solar cell panel 200, the power consumption amount of the ventilation device 500, and the like when the driver indicates on the search condition setting screen that importance is attached to the charging of the battery 300. This is an example of the “evaluation result” according to the present invention in which the parking lot candidates are evaluated.

  Here, as more sunlight information is accumulated in the sunlight information DB 832 and the sunlight information DB 22A, in determining the parking lot of the vehicle 10A, which parking lot is most suitable for charging the battery 300 in the future. It becomes possible to judge accurately.

In the present embodiment, the sunlight information includes the irradiation state of the sunlight, the position of the vehicle, and the weather conditions in association with each other. Furthermore, the sunlight irradiation state (the amount of power generated by the solar cell panel 200, the power consumption of the ventilation device 500, the vehicle interior temperature Tmp, etc.) is actually measured as accompanied by actual phenomena. Even if there is no sunlight information that perfectly suits the parking lot candidate, the parking information suitable for the driver's intention can be obtained by referring to the sunlight information corresponding to the similar position, similar time zone or similar weather. This makes it possible to select a car park accurately.
<Third Embodiment>
Next, a parking position guidance process executed by the ECU 100 will be described as a third embodiment of the present invention with reference to FIG. FIG. 12 is a flowchart of the parking position guidance process. It is assumed that the system configuration according to the third embodiment is equivalent to the solar information utilization system 1 according to the first and second embodiments.

  In FIG. 12, the ECU 100 determines whether route guidance is being performed by the car navigation device 800 (step S301). Such route guidance includes guidance to a parking lot set as a destination according to the second embodiment. When route guidance is not being performed (step S301: NO), the ECU 100 repeatedly executes step S301 to control the process substantially to a standby state.

  On the other hand, when route guidance is being performed (step S301: YES), the ECU 100 determines whether or not the route guidance destination has approached (step S302). Whether or not the vehicle has approached the destination can be determined based on, for example, whether or not the remaining distance to the destination has decreased to a predetermined value or less. When the destination is not approaching (step S302: NO), the ECU 100 returns the process to step S301.

  If the destination is approaching (step S302: YES), the ECU 100 determines whether there is a parking lot at the destination (step S303). Whether or not there is a parking lot at the destination can be determined by referring to the map information DB 831. Further, as shown in the second embodiment, when the parking lot itself is the destination, the determination branch related to step S303 branches unconditionally to the “YES” side.

  When there is no parking lot (step S303: NO), the ECU 100 searches for a parking lot near the destination (step S306), and proposes it to the driver via display control on the display 850 (step S307). At this time, for the search for the optimum parking lot according to step S306, the parking lot search based on the sunlight information as exemplified in the second embodiment (for example, the most solar parking in the expected parking time zone and parking time). It is possible to apply a search for a parking lot that can enjoy the benefits of light.

  When the optimum parking lot is proposed, the ECU 100 determines whether or not the driver has accepted the proposed parking lot (step S308). When the proposed parking lot is not accepted (step S308: NO), the ECU 100 returns the process to step S301 and repeats a series of processes. On the other hand, when the proposed parking lot is accepted (step S308: YES), the ECU 100 starts route guidance to the proposed parking lot and at the same time determines whether or not the proposed parking lot has been approached (step S309). ). In this case, “approach” is defined by a distance shorter than the approach to the destination according to step S302. If the proposed parking lot has not yet been approached (step S309: NO), the ECU 100 repeatedly executes step S309 and continues route guidance to the proposed parking lot.

  On the other hand, when approaching the proposed parking lot (step S309: YES), or when there is a parking lot at the destination in step S303 (including the case where the parking lot is the destination) (step S303: YES), The ECU 100 acquires the optimal parking position (step S304) and displays the optimal parking position teaching screen on the display 850 to propose the acquired optimal parking position to the driver (step S305). The proposal of the optimal parking position is continued until the parking of the vehicle 10A is completed. When the parking is completed, the process returns to step S301.

  Here, the details of the optimum parking position teaching screen will be described with reference to FIG. FIG. 13 is a schematic diagram showing an example of the optimum parking position teaching screen. In the figure, the same reference numerals are given to the same parts as those in the previous figures, and the description thereof will be omitted as appropriate.

  In FIG. 13, the optimum parking position teaching screen shows a top view of a proposed and accepted parking lot or a destination parking lot.

  When there are a plurality of parking spaces in this parking lot (there are 8 locations in the figure), the ECU 100 selects the acquired optimal parking space from the plurality of parking spaces, and selects the selected optimal parking space. The optimal parking position is taught by displaying a vehicle icon (see the black pentagon icon in the figure) representing the vehicle 10A in a portion corresponding to the space.

  In addition, the vehicle icon is an icon whose tip portion indicates the front and can also indicate the direction of the vehicle when the vehicle 10A is parked. Therefore, according to the own vehicle icon, the optimum parking position can be taught including the direction of the vehicle. When the parking space and the parking direction as the optimum parking position are represented by the own vehicle icon, the ECU 100 is information indicating that “the position and orientation of the figure are recommended” (ie, “display information” according to another example of the present invention). Is displayed.

  In obtaining the optimum parking position in step S304, the ECU 100 uses the sunlight information accumulated in the sunlight information DB 832 or the sunlight information DB 22A. That is, the sunlight information includes information on latitude and longitude, and the irradiation state of sunlight for each parking space can be specified. Further, the parking angle θv can be referred to for the parking direction. Based on these, the optimal parking position in the parking lot as the destination can be acquired. In addition, when such a determination of the optimal parking position involves relatively complicated calculation processing, the ECU 100 may request the server device 20 to determine the optimal parking position. In this case, it is only necessary to acquire the determined optimum parking position as data via the network 2, so that the processing burden on the ECU 100 is reduced. In addition, the solar light information utilization system 1 may be constructed so that the server 20 performs processing related to the determination of the optimal parking position in advance regardless of whether or not the ECU 100 requests. The same applies to the parking lot evaluation process according to the second embodiment.

  Here, another example of the optimum parking position teaching screen will be described with reference to FIG. FIG. 14 is a schematic diagram showing another example of the optimum parking position teaching screen. In the figure, the same reference numerals are given to the same portions as those in FIG. 13, and the description thereof is omitted as appropriate.

  In FIG. 14, the optimal parking space is enlarged and displayed on the optimal parking position teaching screen. In this enlarged optimum parking space, the optimum parking position is defined more finely than in FIG. FIG. 14 teaches a position where the vehicle has entered in front of the right rear of the optimum parking space (the left front in the figure) as such a fine optimum parking position.

<Fourth embodiment>
Next, a map information display screen according to the fourth embodiment of the present invention will be described with reference to FIG. In the figure, the same reference numerals are given to the same parts as those in the above-mentioned drawings, and the description thereof will be omitted as appropriate.

  In FIG. 15, the display screen of the display 850 displays a map information display screen displayed during normal route guidance. Here, for easy understanding, when it is assumed that the position of the parking lot is represented as a parking lot icon P0 on one map information display screen, the ECU 100 refers to the sunlight information, and indicates these parking lots to the solar battery panel 200. The power generation amount or the charge amount of the battery 300 is evaluated to be divided into a plurality of levels.

  When the classification ends, the ECU 100 changes the parking lot icon from the parking lot icon P0 to the parking lot icon P2 for the parking lot corresponding to the division with the largest amount of power generation or charging. In addition, the parking lot icon is changed from the parking lot icon P0 to the parking lot icon P1 for the parking lot corresponding to the category with the next largest power generation amount or charging amount.

  Thus, according to the present embodiment, parking is possible on the map information display screen where sunlight can be effectively used even during normal route guidance where the driver is not particularly interested in parking. The parking lot is displayed as an icon having a very high visual effect.

  For this reason, it is possible to always encourage the driver to effectively use sunlight as long as the effect of normal map display is not impaired. Further, since the parking lot icon whose display mode has been changed in this way can be a kind of video information under consciousness, the driver can recognize the existence of a parking lot that can effectively use sunlight unconsciously. . In some cases, it is possible to determine a parking lot that can effectively use sunlight without relying on the car navigation device 800 when searching for a parking lot.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the use of sunlight information with such a change. The apparatus is also included in the technical scope of the present invention.

  The present invention can be used for a mobile object provided with a solar power generation device such as a solar battery.
