Description

NAVIGATION SYSTEM
TECHNICAL FIELD
The invention relates to a vehicle navigation system, more specifically to those navigation systems arranged to display refuelling locations on a map.
BACKGROUND INFORMATION
A vehicle navigation system, particularly a car navigation system, includes an electronic map (E-map). The E-map includes parameters such as route information, including roads, together with points of interest, including refuelling locations. The E-map is typically linked to a positioning system such as a global positioning system (OPS). The GPS is arranged to detect and plot the current vehicle location on the E-map. A driver of the vehicle can thus understand the vehicle's position relative to the roads and refuelling locations provided on the E-map.
An E-map may also be able to show various fuel specific parameters relating to each of the refuelling locations. For example, the fuel specific parameters may include fuel type, fuel brand, fuel price, and fuel availability for each refuelling locaton. The fuel data is usually stored as electronic data on a memory unit of the navigation system.
In order to update the route information and fuel parameters on the E-map it is necessary to remove the navigation system from the vehicle and plug the navigation system into a computer or the like in order to download an update. Such updates are blanket updated which includes all of the route information and fuel parameters stored on the E-map.
It is an object of the present invention to improve on the prior art.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention there is provided a navigation system for a vehicle comprising a mapping module including a set of refuelling locations, the mapping module arranged to determine the position of the system relative to the fuelling locations; a learning module arranged to learn the refuelling locations most frequented by the vehicle; and a communication module arranged to obtain a selective set of fuel parameters relating to the most frequented refuelling locations.
Downloading only a selective set of fuel parameters based on the most frequented fuelling locations reduces the burden on the hardware of the navigation system, for example, a reduced amount of memory s required, the data set is a lot smaller than a blanket update and so the update time together with data usage when updating fuel parameters is improved.
The navigation system may comprise a display module arranged to display the fuel parameters and the most frequented refuelling locations on an E-map. Displaying the fuel parameters in the most frequented refuelling locations on the E-map is advantageous from the drivers point of view since all of the information (e.g. refuelling is location and fuel parameters) is contained in one location.
The fuel parameters may be displayed on the E-map at the locations of the respective refuelling location. Displaying the fuel parameters at the locations of the respective refuelling locations further improves the impact on the driver since the relevant information has been matched up.
The communication module may be arranged to download the refuelling parameters over an electromagnetic medium. Downloading the fuel parameters over an electromagnetic medium is advantageous because the update of the fuel parameters can be undertaken without removing the navigation system from the vehcle to plug it into an external PC.
The electromagnetic medium may be selected from the list, but not limited to Wi-Fi, 3G, and 40. Wi-Fi, 30 and 40 allow for the update to be undertaken automatically so whilst the vehicle is in use. The selective downloading fuel parameter is particularly important with such electronic media since with such media it is often desirable to reduce the data usage during download.
The fuel parameters may be selected from the list of fuel price, fuel brand, fuel type, fuel availability and fuel quantity.
The learning module may be arranged to communicate with a driver identification module to identifying a driver of the vehicle, the learning module being arranged to learn the refuelling locations most frequented by the vehicle when the identified driver is driving. This is particularly advantageous where there is more than one driver of the vehicle using the navigation system. In such a case, the driver using the vehicle at any given time will be able to access the respective fuel parameters relevant to the most frequented refuelling locations.
The communication module may be arranged to obtain the selective set of fuel parameters relating only to the most frequented refuelling locations associated with the identified driver of the vehicle.

BRIEF DESCRIPTION OF THE DRAWINGS
The invention is best described with reference to the accompanying figures, in which; Figure 1 shows a system diagram of the navigation system; and Figure 2 shows a flow diagram of the navigation system in operation.
DETAILED DESCRIPTION
With reference to figure 1, a vehicle 8 such as a car includes a navigation system 10.
The navigation system 10 includes a mapping module 12, a learning module 14, a control module 18 and a display module 20.
The mapping module 12 includes route information such as roads together with refuelling locations and other points of interest. Information relating to specific points of interest such as the refuelling locations to the route information is also stored on the mapping module. The mapping module 12 also includes a global positioning system (GPS). The GPS is arranged to determine the vehicle's location. The mapping module 12 uses the vehicle location information to determine the vehicles current location relative to the route information and the refuelling locations. The mapping module 12 is communicatively linked to the learning module 14.
The learning module 14 is able to receive inputs from the mapping module and monitor the vehicle's location relative to the route information and refuelling locations over time. The learning module includes an algorithm. The operation of the algorithm is described in more detail below. In summary, the algorithm is able to determine a fuel usage trend with regards to the vehicle's usage and filter the refuelling locations such that a set of refuelling locations most frequented by the vehicle can be determined.
The filtering is achieved by determining a frequency for each refuelling location. Any refuelling locations having a frequency value above a predetermined threshold are added to the fuel usage trend and classified as a refuelling location which the vehicle frequents.
is The learning module 14 is also communicatively linked to a driver identification module 16. The driver identification module 16 is external to the navigation system 10. The learning module 14 is able to receive information from the driver identification module 16 as to the current driver of the vehicle. The driver identification modue includes a receiver arranged to detect a near frequency communication device such as an RFID chip stored on a key fob or car key. In such an arrangement, each driver of the vehicle has a designated car key or key fob. The driver identification module 16 can thus detect the identification of the driver by the presence of a specific car key or key fob.
The learning module 14 is thus able to determine a fuel usage trend of the most frequented refuelling locations associated with the identified driver of the vehicle.
The control module 18 includes a processor and a memory unit. The memory unit includes a non-volatile memory component. The information from the mapping module 12 and the driver identification module 16 together with the algorithm of the learning module 14 are stored as electronic data on the non-volatile memory component of the control module 18. The processor of the control module 18 executes the stored data in order to determine the fuel usage trend for each driver of the vehicle. The control module 18 is communicatively linked to a display module 20. The control module 18 is arranged to configure the display module 20 to display an electronic map (E-map) 22.
The E-map shows the route information and refuelling locations together with the other
S
points of interest if desired. After the fuel usage trend has been established for each driver, the refuelling locations most frequented by the identified driver of the vehicle are displayed on the E-map 22 alone i.e. without any other (non-frequented) refuelling locations.
The control module 18 is communicatively linked to a fuel parameter database 24. The database 24 is external to the vehicle on a remote server. The control module 18 has a transceiver in order to communicate with the fuel parameter database 24. The transceiver is arranged to communicate with the fuel parameter database by an electromagnetic medium 26. The electromagnetic medium 26 is, but not limited to, 3G or 4G. In addition, the electromagnetic medium 26 may also be Wi-Fi based.
The display module 20 has a display and more specifically a flat screen colour display.
The display is built into the vehicle dashboard. The display module 20 may also have a IS touch screen function allowing a user to input data such as preferred destination. The E-map 22 is arranged to provide directions to the driver and also a plan view of the route.
With reference to Figure 2, the navigation system operates by first obtaining refuelling locations together with any other route information as shown at block 100. At block 102 the relative position of the vehicle is determined relative to the refuelling locations. At block 104 the driver ID of the driver currently driving the vehicle is determined by the driver identification module.
The most frequently visited refuelling locations for the driver are determned at block 106. As described above, the algorithm of the learning module 14 determines the most frequently visited refuelling locations. The algorithm works in two principle phases.
The first phase is a learning phase and the second phase is a control phase. The learning phase initiates by starting a cycle count, n, where each count corresponds to a refuel of the vehicle. The control phase starts when the count, n, is greater than a count threshold, K, such as 10 refuels. The location of the vehicle is stored by the learning module at each count, n. The number of times the vehicle has refuelled at a location is assigned a value, f. When the ratio of f/K is greater than or equal to a predetermined fuel usage trend value, such as 0.3, the respective refuelling location is classified as a frequented refuelling location. For a ratio of f/K less than the predetermined fuel usage trend value, in this case 0.3, the respective refuelling location is classified as an infrequent location. The algorithm continues tc update over time such that factors such as a change in employment or residential location of the driver of the vehicle are taken into account.
At block 108, the navigation system 10 requests to download a set of fuel parameters for the selected list of frequented refuelling locations for the current driver of the vehicle. The navigation system 10 thus downloads the selected fuel parameters over the electromagnetic medium 26 from the fuel parameters database 24. Since only a selective list of fuel parameters are downloaded, as opposed to a blanket download of all fuel parameters for every refuelling location, the memory usage of the control module 18, processing of the stored fuel parameters, and data usage in downloading the fuel parameters are all improved.
IS
At block 112 the navigation system 10 displays the selected fuel parameters on the E-map 22 of the display module together with the refuelling locations corresponding to each set of fuel parameters downloaded. The fuel parameters are matched to each refuelling location and presented together on the E-map 22.
The aforementioned embodiment may be modified in various ways without departing from the scope of the invention. The driver identification module system 16 may be controlled by the control module 18 as part of the navigation system. In addition, the mapping module 20 may be defined outside of the navigation system's boundary. Also, the specific algorithm and the quoted values defined hereinabove illustrate one of several possible algorithms which can govern the navigation system 10.
Various modifications and alternatives to the aforementioned system or envisage which do not depart from the scope of the present invention. 3°
