Description

Title of the invention: Management of the sharing of private data from a motor vehicle by means of a touch screen of a human-machine interface of the vehicle Technical field of the invention

[0001] The present invention relates to the field of human-machine interfaces for motor vehicles. The invention relates in particular to a method for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface is broadcast. The invention also relates to a device implementing such a method. The invention applies to motor vehicles such as land motor vehicles, in particular cars. State of the prior art

[0002] It is known that modern motor vehicles increasingly use connected services to enable the provision of various functionalities, including driver assistance functionalities. In this context, it happens that private data relating to vehicle users (e.g. location, identity, etc.) are shared from the vehicles with remote third parties. And to manage these private data sharing arrangements, the user must generally navigate through menus that allow the operation of the vehicle components to be configured. However, this need to navigate through configuration menus proves to be relatively restrictive and time-consuming, which results in a lack of ergonomics.Furthermore, known motor vehicle human-machine interfaces generally do not allow the vehicle user to know at any given time which functionalities use private data. As a result, known motor vehicle human-machine interfaces remain deficient in terms of their ergonomics when it comes to managing the sharing of private data from vehicles. Summary of the invention

[0003] The invention seeks to address this problem. In particular, it aims to provide a solution for ergonomically controlling the sharing of private data from a motor vehicle. Another objective of the invention is to provide means that allow the user of a motor vehicle to easily know the vehicle's functionalities that use private data. In this way, the invention seeks to improve the ergonomics of human-machine interfaces in motor vehicles.

[0004] In order to achieve these aims, the invention relates, according to a first aspect, to a method of managing, by a computer device on board a motor vehicle, the operation of a touch screen of a human-machine interface of the vehicle on which a graphical interface is broadcast, the method comprising the steps of: i. causing the display in the graphical interface of a pictogram which provides information on the subject of the sharing of private data from the vehicle; ii. determine whether support is being applied at the pictogram; and, where this is established to be the case, iii. cause, depending on the type of support made, the prevention of sharing private data from the vehicle, the authorization of sharing private data from the vehicle or the display in the graphical interface of interactive visual content.

[0005] According to a variant, step iii) may comprise a step consisting of causing the display in the graphical interface of interactive visual content if it is established that a short press is made.

[0006] According to another variant, the visual content may contain an interactive zone making it possible to prevent or authorize the sharing of private data from the vehicle with regard to a functionality of the vehicle which uses such data.

[0007] According to yet another variant, step iii) may comprise a step of causing the prevention or authorization of the sharing of private data from the vehicle if it is established that a long press is made.

[0008] According to a second aspect, the invention relates to a device for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface is broadcast, the device comprising at least one information processing unit, comprising at least one processor, and a data storage medium configured to implement a method as described above.

[0009] According to a third aspect, the invention relates to a computer program comprising program code instructions for executing the steps of a method as described above when said program is executed by at least one processor.

[0010] According to a fourth aspect, the invention relates to a medium usable in a computer on which a program as described above is recorded.

[0011] According to a fifth aspect, the invention relates to a motor vehicle comprising a device as described above. Brief description of the figures

[0014] [Fig.2] is a functional diagram of a device according to the invention;

[0015] [Fig.3] is a flowchart of the steps of a method according to the invention; and

[0016] [Fig.4] illustrates at least one step of the method according to the invention. Detailed description of the invention

[0017] In [Fig.l] a motor vehicle 1 according to the invention is schematically illustrated. This is conventionally equipped with a human-machine interface 2, which comprises at least one touch screen 3 on which a graphical interface is broadcast. Advantageously, this graphical interface contains a pictogram 4 which provides information about the sharing of private data from the vehicle, for example by means of two arrows which light up in a particular color when such data is transmitted. Preferably, the pictogram 4 is positioned within a status bar 5, which is for example displayed at the top of the graphical interface. The vehicle 1 according to the invention also incorporates a radiofrequency signal communication system 6 in order to be able to communicate (i.e. transmit and receive data) by means of conventional mobile communication networks and protocols (egV2X, ITS-G5, 3 / 4 / 5G) with remote communicating entities.

[0018] Advantageously, the vehicle 1 according to the invention also carries a device 100 for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface is broadcast within the meaning of the present invention, as described below, which implements a method for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface is broadcast within the meaning of the present invention, as briefly summarized below and described in detail below.

[0019] When implementing the method according to the invention, the device 100 according to the invention advantageously causes the display of the pictogram 4 in the status bar 5, then it continuously monitors whether tactile interactions are carried out at the level of the pictogram 4. And when it establishes that this occurs, it then causes, depending on the type of press carried out, short or long, either the display on the screen of interactive visual content, which allows the user to know the functionalities of the vehicle 1 which use or have used private data and which makes it possible to activate or deactivate the sharing of this data with regard to one or other of these functionalities, or the prevention or authorization of the sharing of private data.The user of vehicle 1 can thus easily control the sharing of private data from vehicle 1, whether globally or partially, by simply pressing pictogram 4. This is the . way that the ergonomics of the human-machine interface 2 of the vehicle 1 is significantly improved in terms of managing the sharing of private data.

[0020] The device 100 for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface according to the invention is broadcast is illustrated in [Fig. 2]. It is essentially a computer device, which comprises at least one information processing unit 101, comprising one or more processors, a data storage medium 102, on which is recorded in particular a program which comprises program code instructions for the execution of the steps of the method according to the invention described below, and an input and output interface 103 allowing the reception and transmission of data.

[0021] Preferably, the device 100 according to the invention is hosted on an independent computer and it interacts via its input and output interface 103 and by means of a wired communication network of the vehicle (e.g. CAN, Ethernet, MOST) - shown in [Fig.l] by the two-way arrows - with the human-machine interface 2 of the vehicle 1, in particular its screen 3, and with the radiofrequency signal communication system 6. Alternatively, the device 100 according to the invention is partially or fully part of one or other of these components of the vehicle 1. As a result, the device 100 according to the invention can, in particular, determine whether a press is made at the pictogram 4, it can cause the display on the screen 3 of interactive visual content and it can cause the prevention or authorization of the sharing of private data in a global or partial manner.

[0022] According to the invention, all the elements described above contribute to enabling the implementation of a method for managing the operation of a touch screen of a human-machine interface of a motor vehicle on which a graphical interface is broadcast, as described below in connection with figures 3-4.

[0023] [Fig.3] illustrates by means of a flowchart the steps of the method according to the invention.

[0024] According to a first step 301 of the method according to the invention, the device 100 according to the invention advantageously causes the display on the screen 3 of the pictogram 4 which provides information about the sharing of private data from the vehicle 1. According to an exemplary embodiment, the pictogram 4 thus displayed takes the form of two arrows which light up in a particular color when such data is transmitted from the vehicle 1. Preferably, the two arrows are displayed in a first color when the sharing of private data is not authorized and in a second color when the sharing of private data is authorized. And to implement this step, the device 100 according to the invention interacts with the radio frequency signal communication system 6, which conventionally knows the types of data that are transmitted from the vehicle 1.

[0025] Then, according to a second step 302 of the method according to the invention, the device 100 according to the invention determines whether a press is made at the pictogram 4. In other words, the device 100 according to the invention continuously interacts with the screen 3 or the human-machine interface 2 to determine whether a press is made at the pictogram 4. And when it establishes that this occurs, it then carries out the following step of the method according to the invention described below.

[0026] According to a third step 303 of the method according to the invention, the device 100 according to the invention causes, depending on the type of support carried out, the prevention of the sharing of private data from the vehicle, the authorization of the sharing of private data from the vehicle or the display in the graphical interface of interactive visual content.

[0027] Preferably, when it establishes that it is a long press which is carried out at the level of the pictogram 4, the device 100 according to the invention causes the prevention or the authorization of the sharing of private data from the vehicle 1, and this according to an operating state at the current time. Thus, if the operating state at the current time is such that the sharing of private data from the vehicle 1 is prevented, the device 100 according to the invention then causes the authorization of the sharing of private data from the vehicle 1. Conversely, if the current operating state is such that the sharing of private data from the vehicle 1 is authorized, the device 100 according to the invention then causes the prevention of the sharing of private data from the vehicle 1.In other words, a long press on the pictogram 4 advantageously allows the sharing of private data from the vehicle 1 to be authorized or prohibited in a global manner. And to implement this step, the device 100 according to the invention interacts with the radiofrequency signal communication system 6, the latter being configured to accept a command to authorize or prevent the sharing of private data from the vehicle when data characterizing an authorization or prevention instruction are transmitted to it by the device 100 according to the invention.

[0028] Conversely, if it establishes that it is a short press which is carried out, the device 100 according to the invention then causes the display in the graphical interface of an interactive visual content, as is illustrated schematically in [Fig. 4]. Advantageously, such content identifies a functionality of the vehicle 1 which uses at the current time or which has previously used private data, and it contains an interactive zone 7 which advantageously makes it possible to prevent or authorize the sharing of private data from the vehicle 1 with regard to the function identified. The driver can thus easily become aware of the functionalities of the vehicle 1 which use private data, and he can, on a case-by-case basis, prevent or authorize the sharing of such data with regard to one or other of these functionalities by pressing in the corresponding interactive zone 7. And to implement this step, the device 100 according to the invention interacts again with the radiofrequency signal communication system 6, which is conventionally able to determine at any time one or more functionalities of the vehicle 1 which use private data.

[0029] Thus, thanks to the method and the device according to the invention described above, a more ergonomic alternative is provided for controlling the sharing of private data from a motor vehicle. The invention therefore significantly improves the ergonomics of the human-machine interfaces of motor vehicles in terms of managing the sharing of private data from the vehicles.
