The charging location may comprise any location which has enough incident solar power to enable charging of the vehicle 31. The vehicle 31 may be moved autonomously to the charging location. A notification may be provided to the user of the vehicle 31 to provide an indication of the location to which the vehicle 31 has been moved.
In some examples the vehicle 31 may be moved small distances. For example the vehicle 31 may be moved a few meters to move out of the shade and into direct sunlight. In other examples the vehicle may be moved longer distances such as hundreds of meters or further, for example, if the vehicle 31 is parked in a very build up environment it may be necessary to travel a longer distance to find a location which is not in the shade. When determining the solar power charging strategy 27 the energy requirements for moving to and from the charging location may be taken into account.
The solar power charging strategy 27 may comprise a schedule of when a solar powered vehicle 31 should leave a charging location. For example the vehicle 31 may be instructed to leave the charging location and return to its original location in time for the user to start their next expected journey. In other examples the vehicle 31 may be instructed to leave the charging location in order to enable one or more other solar powered vehicles 31 to access the charging location.
In some examples the solar powered vehicle 31 may be scheduled to leave a location if it is no longer obtaining sufficient solar power. It is to be appreciated that the solar power distribution depends on parameters such as the positions of shadows and the current weather conditions which will change over time. Therefore a solar powered vehicle 31 may be scheduled to move from a first position to a second position once the first position stops receiving enough solar power.
In some examples the server 21 may be configured to obtain information relating to the charging speed or solar power obtained in their current location. This could be achieved by obtaining information relating to the stored power levels as a function of time. This information could be used to determine and/or update a charging strategy 27.
At block 83 the server 21 enables the solar powered vehicles 31 to access the charging strategy 27. The server 21 may transmit the solar power charging strategy 27 to one or more of the vehicles 31 via a communication link 45. In some examples the server 21 may transmit the solar power charging strategy 27 to a first vehicle 31. The first vehicle 31 may then be configured to send the solar power charging strategy 27 to other nearby vehicles 31. For example, the first vehicle 31 may be configured to send the solar power charging strategy 27 to other nearby vehicles 31 via a low power communication link 47. This may reduce the power requirements for accessing the solar power charging strategy 27.
At block 85 the one or more solar powered vehicles 31 obtain access to the charging strategy 27. The solar power charging strategy 27 may be received by the transceiver 23 and stored in the memory circuitry 7 of the solar powered vehicle 31.
At block 87 the solar power charging strategy 27 is implemented and the position of the vehicle 31 is controlled in accordance with the instructions within the solar power charging strategy 27.
The blocks illustrated in FIGS. 5 to 7 may represent steps in a method and/or sections of code in the computer program 9. The illustration of a particular order to the blocks does not necessarily imply that there is a required or preferred order for the blocks and the order and arrangement of the block may be varied. Furthermore, it may be possible for some blocks to be omitted.
For example, in the method of FIG. 7 the solar powered vehicle 31 obtains the information relating to the expected power requirements of the vehicle 31 and then sends this to the server 21. It is to be appreciated that in other examples this information could be obtained by the server 21 directly. For example, the server 21 may be configured to access calendar and diary information of the user or to access information such as traffic updates. In other examples some of the information may be obtained by the vehicle 31 and some of the information may be obtained by the server 21 directly.
It is to be appreciated that some blocks of the methods may be repeated as necessary. For example if the situation in the location of a vehicle 31 changes then further information may be provided to the server 21. For example, the weather may change unpredictably so that the cloud cover may increase or decrease, new vehicles 31 which may need to be charged may be positioned near the vehicle 31, or other vehicles 31 may be moved from a charging location. In such examples the server 21 may use the further information to modify the charging strategy to incorporate the further information.
In some examples the user of the vehicle 31 may be able to apply constraints to the charging strategy 27. For instance the user may be able to define when and/or where he would like to collect the vehicle 31. In some examples the user may be able to define the locations and/or range which the vehicle 31 is permitted to move during charging.
The above described disclosure provides apparatus, methods and computer programs which enable a plurality of solar powered vehicles 31 to be charged efficiently.
The examples enable a solar power charging strategy 27 to be determined which may incorporate instructions for a plurality of vehicles 31. This may ensure that each of the vehicles 31 obtains adequate charging and that charging locations are not unnecessarily occupied by vehicles which do not need to obtain further power.
The examples also enable a plurality of different types of information to be accessed to ensure that the charging strategy has accurate and up to date information. This may comprise information obtained from sensors 35 on the vehicle 31 as well as information accessed from one or more servers 21. This may ensure that all vehicles 31 incorporated into the strategy receive sufficient levels of power.
The examples are also configured to take into account information which may change over time. It is to be appreciated that the charging positions for the vehicles will be different at different times of the day and the above described examples enable this to be taken into account.
The term ‘comprise’ is used in this document with an inclusive not an exclusive meaning. That is any reference to X comprising Y indicates that X may comprise only one Y or may comprise more than one Y. If it is intended to use ‘comprise’ with an exclusive meaning then it will be made clear in the context by referring to “comprising only one . . . ” or by using “consisting”.
In this brief description, reference has been made to various examples. The description of features or functions in relation to an example indicates that those features or functions are present in that example. The use of the term ‘example’ or ‘for example’ or ‘may’ in the text denotes, whether explicitly stated or not, that such features or functions are present in at least the described example, whether described as an example or not, and that they can be, but are not necessarily, present in some or all other examples. Thus ‘example’, ‘for example’ or ‘may’ refers to a particular instance in a class of examples. A property of the instance can be a property of only that instance or a property of the class or a property of a sub-class of the class that includes some but not all of the instances in the class.
Although embodiments of the present invention have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the invention as claimed. For example in the above described examples all of the vehicles 31 are solar powered vehicles 31. It is to be appreciated that the system 41 may also be used to control the position of non-solar powered vehicles. For example if it is detected that a non-solar powered vehicle is parked in a sunny location which has high levels of incident solar power then the non-solar powered vehicle could be moved to a different location to ensure that the sunny location is available for a solar powered vehicle.
Features described in the preceding description may be used in combinations other than the combinations explicitly described.
Although functions have been described with reference to certain features, those functions may be performable by other features whether described or not.
Although features have been described with reference to certain embodiments, those features may also be present in other embodiments whether described or not.
Whilst endeavoring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
