Description

Title of the invention: Method and device for controlling a vehicle navigation system. Technical field

[0001] The present invention relates to methods and devices for controlling a navigation system of a vehicle, in particular an automobile. The present invention relates in particular to a method and a device for selecting a destination used by a navigation system to calculate a road route between a current position of the vehicle and the selected destination. Technological background

[0002] Vehicles are known which have navigation systems implemented by one or more computers associated with a touch screen, i.e. a screen comprising a touch interface. Map data are displayed in a first zone of the touch screen. These map data can be displayed either in the form of a two-dimensional geographical map or in the form of a scrolling map when the vehicle moves along a road route. A human-machine interface, called HMI, is also displayed in a second zone of the touch screen to allow a user of the vehicle to manually enter geographical location search criteria such as keywords or a postal address. The navigation system is then configured to search a list of at least one geographical location which corresponds to the search criteria.Each geographical location may correspond to a point of interest (viewpoint of a landscape, remarkable site, etc.) or a place such as a restaurant, cinema, etc. The list of at least one geographical location is then displayed in a list of at least one graphic object in a third zone of the touch screen, each first graphic object being determined to represent a geographical location from the list of at least one geographical location. The vehicle user can then refine the search criteria or press a graphic object displayed in the third zone to indicate that he wishes to select the geographical location associated with this graphic object as a destination. The navigation system then calculates a road route between the current position of the vehicle and the destination thus selected.

[0003] In navigation systems, the destination is selected by a vehicle user by pressing a graphic object from a list of graphic objects displayed in a third area of ​​the touch screen. However, the display of this list of graphic objects is independent of the map data displayed in the first area of ​​the touch screen, which can be disturbing for a vehicle user because the graphic objects that represent the geographical locations resulting from the search do not correspond to the cartographic data displayed in the first zone.

[0004] Current navigation systems need to be improved, particularly in terms of interaction with a vehicle user and in terms of consistency of the information displayed. Summary of the present invention

[0005] An object of the present invention is to solve at least one of the problems of the technological background described above.

[0006] Another object of the present invention is, for example, to improve the control of a navigation system of a vehicle, in particular an automobile.

[0007] Another object of the present invention is, for example, to improve the user experience with regard to the information associated with a navigation system.

[0008] According to a first aspect, the present invention relates to a method for controlling a navigation system of a vehicle comprising a touch screen, the method comprising the following steps: - obtaining initial data defining a list of geographical locations; - control of display of a list of first graphic objects representative of the list of geographical locations in a first zone of the touch screen, each first graphic object being representative of a geographical location in the list of geographical locations; - determination of cartographic data defining a geographical area circumscribing the geographical locations of the list of geographical locations; - control of display of cartographic data and of a list of second graphic objects representative of the list of geographical locations in a second zone of the touch screen, each second graphic object being representative of a geographical location in the list of geographical locations; - reception of second data representative of a touch press on a first or a second graphic object; - selection of a destination for the navigation system based on the second data.

[0009] The method is advantageous because it creates a link between the list of first graphic objects displayed in the first area of ​​the touch screen and the list of second graphic objects displayed in the second area of ​​the touch screen. This graphic link is dynamic, that is to say that any change of locations in the list of geographical locations is reflected in the list of first graphic objects and in the list of second graphic objects. In addition, the map data displayed in the second area of ​​the touch screen are also dynamically modified. so that this cartographic data corresponds to a geographical area which circumscribes the list of geographical locations.

[0010] The method is advantageous because it offers a means of interaction with a list of second graphic objects displayed in the second zone of the touch screen superimposed on map data. This means of selecting a destination (other than the selection of a geographical location by touching a first graphic object displayed in the first zone of the touch screen) is more user-friendly for a vehicle user.

[0011] According to a variant, the method further comprises the following steps: - obtaining third data representative of search criteria; and - searching the list of geographical locations in relation to the third data.

[0012] According to a particular and non-limiting exemplary embodiment, at least one search criterion is defined by interaction of a user of the vehicle with a human-machine interface displayed on the touch screen.

[0013] According to a particular and non-limiting exemplary embodiment, the third data are obtained from a memory.

[0014] According to a particular and non-limiting exemplary embodiment, the third data are obtained from a communication channel of a communication network.

[0015] According to a particular and non-limiting exemplary embodiment, the third data are representative of at least one of the following elements: - a preference of a user of the vehicle; - a condition of a vehicle component; - an event ; - a frequency of appearance of geographic locations in a search history; - statistics on the number of visits to geographical locations.

[0016] According to a particular and non-limiting exemplary embodiment, the search for the list of geographical locations is limited to a circular geographical area of ​​predetermined radius and centred on a geographical position of the vehicle.

[0017] According to a second aspect, the present invention relates to a device for controlling a navigation system of a vehicle, the device comprising a memory associated with a processor configured for implementing the steps of the method according to the first aspect of the present invention.

[0018] According to a third aspect, the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention or a system as described above according to the third aspect of the present invention.

[0019] According to a fourth aspect, the present invention relates to a computer program which comprises instructions adapted for executing the steps of the method according to the first aspect of the present invention, in particular when the computer program is executed by at least one processor.

[0020] Such a computer program may use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.

[0021] According to a fifth aspect, the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for carrying out the steps of the method according to the first aspect of the present invention.

[0022] On the one hand, the recording medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM memory, a CD-ROM or a microelectronic circuit type ROM memory, or a magnetic recording means or a hard disk.

[0023] Furthermore, this recording medium may also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or hertzian radio or by self-directed laser beam or by other means. The computer program according to the present invention may in particular be downloaded from an Internet-type network.

[0024] Alternatively, the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to perform or to be used in performing the method in question. Brief description of the figures

[0032] A method and a device for controlling a vehicle navigation system will now be described in the following with joint reference to Figures 1 to 6. The same elements are identified with the same reference signs throughout the description which follows.

[0033] The terms "first(s)", "second(s)" (or "first(s)", "second(s)"), etc. are used in this document by arbitrary convention to enable different elements (such as operations, means, etc.) implemented in the embodiments described below to be identified and distinguished. Such elements may be distinct or correspond to a single element, depending on the embodiment.

[0034] According to a particular and non-limiting example of embodiment of the present invention, the control of a navigation system of a vehicle comprises obtaining first data defining a list of geographical locations. These first data are for example obtained following a search for geographical locations on the basis of search criteria set by a user of the vehicle. The display of a list of first graphic objects in a first zone of the touch screen is controlled. The list of first graphic objects is representative of the list of geographical locations, each first graphic object being representative of a geographical location in the list of geographical locations. Cartographic data is determined. The cartographic data defines a geographical area circumscribing the geographical locations in the list of geographical locations.The display of map data and a list of second graphical objects in a second area of ​​the touchscreen is controlled. The list of second graphical objects is representative of the list of geographic locations, each second graphical object being representative of a geographic location in the list of geographic locations. Second data is received. The second data is representative of a touch press on a first or second graphical object. A destination of the navigation system is selected based on the second data.

[0035] The present invention allows a visualization of points of interest or addresses of geographical locations by superimposing cartographic data corresponding to an area circumscribing these points of interest or geographical locations corresponding to the addresses. The geographical area is tightened around these points of interest and geographical locations which allows a better visualization of these points of interest or geographical locations on a zoomed geographical map.

[0036] [Fig. 1] schematically illustrates a part of the passenger compartment of a vehicle 10, according to a particular and non-limiting exemplary embodiment of the present invention.

[0037] The vehicle 10 corresponds for example to a vehicle with a thermal engine, with electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle comprising a passenger compartment or at least equipped with a touch display screen, for example an automobile, a truck, a bus, a motorcycle.

[0038] The vehicle 10 advantageously incorporates a display system comprising a touch screen 13 (i.e. a screen comprising a touch interface) and a computer configured to control the display of graphic objects on the touch screen 13. The computer corresponds for example to the computer of the infotainment system, called the IVI computer (from the English “In-Vehicle Infotainment” or in French “Infodivertissement embargo”) of the vehicle 10.

[0039] The touch screen 13 corresponds for example to a display device of the LCD type (from the English “Liquid Crystal Display” or in French “Display à cristals liquide”), for example of the TFT type (from the English “Thin-Film Transistor” or in French “Transistor en film mince”), or OLED type (from the English “Organic Light-Emitting Diode” or in French “Diode électroluminescente biologique”).

[0040] According to a particular embodiment, the display system comprises one or more other screens, for example a screen of a so-called head-up display device or system corresponding for example to a transparent or semi-transparent blade arranged in such a way that a driver seated in the seat 15 sees the graphic object displayed or projected on the transparent blade when the driver drives the vehicle 10.

[0041] Such a display system comprising the touch screen 13 is for example provided or configured to reduce the number of screens present in the vehicle 10, making it possible for example to eliminate the display screen(s) called the instrument panel or dashboard and generally arranged in an area 16 behind the steering wheel 14 in the dashboard 11.

[0042] Graphical objects may be displayed by the touchscreen 13 to form an HMI. A graphical object may comprise data to define a visual representation of this graphical object intended to be displayed on the touchscreen 13. An object graphic object may also comprise interfacing means configured to detect a touch on its visual representation then displayed on a touch screen 13 and to implement a function associated with the command corresponding to the touch. The function may be, for example, a transmission of data associated with the graphic object to the computer of the display system. According to a particular and non-limiting exemplary embodiment, the interfacing means comprise a software application configured for managing interactions between the touch screen 13 and the computer of the display system. Some of these graphic objects may be configured to allow a user of the vehicle 10 to enter a search criterion for a geographical location or a postal address. Other graphic objects may be configured to display a visual representation of a geographical location.The graphic object is then associated with data relating to this geographical location such as, for example, its geographical position or descriptive information about this geographical location. The visual representation of a graphic object corresponds, for example, to a pictogram, an icon or a virtual button (graphic) or a virtual keyboard allowing a user of the vehicle (for example, the driver of the vehicle 10) to interact with the graphic objects displayed on the touch screen 13. The user can then, for example, make a tactile press on a graphic object associated with a geographical location to select this geographical location as a destination so that the navigation system calculates a road route from the current position of the vehicle 10 to this destination thus selected.

[0043] According to a particular and non-limiting exemplary embodiment, a tactile press on a graphic object is a brief press, that is to say the duration of the press on a first or a second graphic object is less than a threshold duration (for example equal to 500 or 1000 ms).

[0044] According to a particular and non-limiting exemplary embodiment, the HMI may comprise voice control means configured so that a user of the vehicle 10 can define one (or even several) search criteria. These voice control means are associated with the device 5 which can then search for geographical locations according to the search criteria received from the voice control means.

[0045] According to a particular embodiment, the vehicle 10 may carry one or more on-board systems each controlled by one or more computers. These computers, with the IVI computer, form for example a multiplexed architecture for the realization of different services useful for the proper functioning of the vehicle and for assisting the driver and / or the passengers of the vehicle in the control of the vehicle 10 via the control of the system(s) embedded in the vehicle 10. The computers communicate and exchange data between them via one or more computer buses, for example a communication bus of the type CAN data bus (from the English "Controller Area Network"), CAN FD (from the English "Controller Area Network Flexible Data-Rate"), FlexRay (according to the ISO 17458 standard), LIN (from the English "Local Interconnect Network") or Ethernet (according to the ISO / IEC 802-3 standard).

[0046] An on-board system in the vehicle 10 corresponds to a navigation system configured to calculate a road route between a current position of the vehicle 10 and a destination selected according to the present invention.

[0047] A process for controlling a navigation system is advantageously implemented by the vehicle 10, for example by a device 5 described in relation to [Fig.5].

[0048] In a first operation, the device 5 obtains first data defining a list of geographical locations 130;.(i=1 to N).

[0049] Preferably, N=5 or 10.

[0050] Each geographic location in the list of geographic locations is a possible destination that can be selected by a user of the vehicle 10.

[0051] In a second operation, illustrated in [Fig.2], the device 5 controls the display of a list of first graphic objects 131; (i=1 to N) in a first zone 131 of the touch screen 13. The list of first graphic objects 131; is representative of the list of geographical locations 130;, each first graphic object 131; being representative of a geographical location 130;. The first zone 131 covers only a part of the total display area of ​​the touch screen 13.

[0052] In a third operation, the device 5 determines cartographic data defining a geographical area circumscribing the geographical locations 130;.

[0053] In a fourth operation, the device 5 controls the display of the map data and a list of second graphic objects 132; in a second zone 132 of the touch screen 13. The list of second graphic objects 132; is representative of the list of geographical locations, each second graphic object 132; being representative of a geographical location 130;.

[0054] The second zone 132 covers only a part of the total display area of ​​the touch screen 13. The first zone 131 and the second zone 132 are separate.

[0055] According to a particular and non-limiting exemplary embodiment, each second graphic object comprises a marker represented by inverted triangles in [Fig.2].

[0056] The present invention is not limited to such a visual representation of a marker but extends to any visual representation of a marker on cartographic data.

[0057] In a fifth operation, the device 5 receives second data representative of a tactile press on a first graphic object 131; or on a second graphic object 132;.

[0058] For example, illustrated in [Fig. 3], the second data are representative of a touch press 140 on a first graphic object 131; or of a touch press 150 on a second graphic object 132; ([Fig. 4]).

[0059] In a sixth operation, the device 5 selects a destination for the navigation system based on the second data, i.e. the selected destination is the geographical location associated with the graphic object having undergone the tactile press.

[0060] The first and second data are for example received via one or more data buses connecting the display system (for example the computer controlling the HMI displayed on the touch screen 13) and the device 5. A touch pressure on a first or second graphic object causes the transmission of the second data to the device 5 so that the latter selects the geographical location associated by the graphic object having undergone the touch pressure as a destination used by the navigation system for calculating a road route.

[0061] According to a variant, the method further comprises the following operations.

[0062] In a seventh operation, the device 5 obtains third data representative of search criteria.

[0063] In an eighth operation, the device 5 searches the list of geographical locations 130; in relation to the third data.

[0064] According to a particular and non-limiting exemplary embodiment, at least one search criterion is defined by interaction of a user of the vehicle with an HMI displayed on the touch screen 13.

[0065] According to a particular and non-limiting exemplary embodiment, the third data are obtained from a memory.

[0066] According to a particular and non-limiting example of embodiment, the memory is embedded in the vehicle 10.

[0067] According to a particular and non-limiting exemplary embodiment, the memory is accessible by the vehicle 10 via a communication channel of a communication network or from a storage device connected to the vehicle 10.

[0068] According to a particular and non-limiting exemplary embodiment, the third data are representative of preferences of a user of the vehicle 10.

[0069] For example, a user preference may indicate that only geographic locations corresponding to service stations or rest areas or restaurants are considered when searching for geographic locations. A criterion search can then favor gas stations or rest areas or remaining as geographic locations from the list of geographic locations.

[0070] According to a particular and non-limiting exemplary embodiment, the third data are representative of a state of a component of the vehicle 10.

[0071] According to a particular and non-limiting exemplary embodiment, a state of a component of the vehicle 10 may define a fuel or charge level of a battery of the vehicle 10. A search criterion may then favor geographical locations close to fueling or electrical research stations. According to another example, a time indicated by an on-board clock of the vehicle 10 may define a context linked to the vehicle 10. For example, at mealtimes, a search criterion may favor geographical locations close to restaurants and in the evening, geographical locations close to cinemas and hotels.

[0072] According to a particular and non-limiting exemplary embodiment, the third data are obtained from a communication channel of a communication network.

[0073] According to a particular and non-limiting exemplary embodiment, the third data are representative of an event such as a promotional period for the sale of products. For example, a search criterion can then be defined to favor geographical locations close to department stores during a sales period.

[0074] According to a particular and non-limiting exemplary embodiment, the third data are representative of a frequency of appearance of geographical locations in a search history. For example, a search criterion can then be defined to favor the geographical locations associated with the highest frequencies of appearance in this search history.

[0075] According to a particular and non-limiting exemplary embodiment, the third data are representative of a statistic of attendance of geographical locations. For example, a search criterion can then be defined to favor the most frequented geographical locations.

[0076] According to an exemplary embodiment, a search criterion may favor one geographic location over another by associating with this geographic location a low weighting value compared to the values ​​associated with other non-favored geographic locations. The geographic locations resulting from the search are then those which are associated with the lowest values.

[0077] According to a particular and non-limiting exemplary embodiment, the list of geographical locations is ordered according to at least one search criterion.

[0078] For example, the list of geographical locations can be ordered according to the preferences of a user of the vehicle 10 or according to a context linked to the vehicle 10 or according to an event or according to a statistic of attendance at these locations. geographical locations or according to the frequency of appearance of these geographical locations in a search history.

[0079] According to a particular and non-limiting exemplary embodiment, the search for geographical locations is limited to a circular geographical area of ​​determined radius and centered around a current geographical position of the vehicle 10, for example a circular geographical area of ​​radius 50 km.
