Description

Title of the invention: Management of the provision of meteorological information by means of a touch screen of a human-machine interface of a motor 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 which contains at least one pictogram which provides information on the temperature of the air outside the vehicle. 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 the instrument cluster of a motor vehicle traditionally displayed an indication of the outside air temperature. It is also known that, in certain recent motor vehicles, a pictogram of a snowflake is generally displayed next to the temperature indication when the outside air temperature falls below a pre-established value (eg 3°C), in order to inform the driver of the risk of black ice.

[0003] However, the limited size of the instrument cluster screens can sometimes prevent the display of this information, in particular due to the increasing need for space to display information relating to the operation of the driver assistance systems that equip most modern motor vehicles. In addition, other concerns related to the ergonomics and aesthetics of vehicle interiors may require the pure and simple disappearance of an instrument cluster arranged behind the steering wheel in favor of a single touch screen placed, for example, at the level of the central console. In this case, the indication of the outside air temperature is generally transferred to the level of the single screen, for example in a status bar which is displayed at the top of the graphical interface broadcast on the screen.And you usually have to access the menus that allow you to configure the operation of the vehicle's components to be able to change the unit of measurement used to display the outside temperature, a process that turns out to be relatively complex and time-consuming, in other words not very ergonomic, especially in the context of driving. In addition, it is generally not possible to prevent the display of the traditional snowflake, even though the display of this in . training may sometimes prove to be of negligible interest, particularly in regions where the outside temperature is low most of the time, and may then risk causing a reduction in perceived quality. Summary of the invention

[0015] Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended figures, in which:

[0016] [Fig-1] is a diagram of a motor vehicle according to the invention;

[0017] [Fig.2] is a functional diagram of a device according to the invention;

[0018] [Fig.3] is a flowchart of the steps of a method according to the invention;

[0019] [Fig.4] illustrates at least one step of the method according to the invention; and

[0020] [Fig.5] illustrates at least one step of the method according to the invention. Detailed description of the invention

[0021] In [Fig.l] a motor vehicle 1 according to the invention is schematically illustrated. It is conventionally equipped with a human-machine interface which comprises at least one touch screen 2 on which a graphical interface is broadcast which contains a first pictogram 3 which provides information on the air temperature outside the vehicle and a second pictogram 4 which provides information on a condition or and / or a meteorological risk, for example in the form of a snowflake to indicate a risk of black ice. Preferably, the first 3 and the second pictogram 4 are positioned within a status bar 5 which is displayed at the top of the graphical interface.

[0022] Advantageously, the vehicle 1 according to the invention also includes 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 which contains at least one pictogram which provides information on the temperature of the air outside the vehicle. vehicle 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 is broadcast a graphical interface which contains at least one pictogram which provides information on the temperature of the air outside the vehicle within the meaning of the present invention, as briefly summarized below and described in detail further below.

[0023] When implementing the method according to the invention, the device 100 according to the invention determines whether tactile interactions are carried out at the level of the first pictogram 3. And when it establishes that this occurs, it then causes the display on the screen of interactive and / or informative visual content depending on the type of interaction which is carried out. Thus, the driver can interact with the first pictogram 3 to, preferably by means of a long press on it, trigger the display of interactive visual content which makes it possible in particular to modify the unit of measurement of the outside air temperature and to activate or deactivate the display of the second pictogram 4.Likewise, the driver can, preferably by means of a short press made at the level of the first pictogram 3, trigger the display of informative visual content which explains a meteorological condition, a meteorological risk and / or a malfunction of a component for measuring the air temperature outside the vehicle 1. Consequently, the management by the driver of the vehicle 1 according to the invention of the provision of meteorological information on board the vehicle is significantly facilitated, and the ergonomics of the human-machine interface of the vehicle 1 is thus improved.

[0024] 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 is broadcast which contains at least one pictogram which provides information on the temperature of the air outside the vehicle according to the invention 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.

[0025] 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 (eg CAN, Ethernet, MOST) - shown in [Fig. 1] by the two-way arrow - with the screen 2. Alternatively, the device 100 according to the invention is an integral part of the screen 2. As a result, the device 100 according to the invention can, in particular, determine whether a press is carried out at the level of the first pictogram 3, and it can cause the display on screen 2 of interactive or informative visual content.

[0026] 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 which contains at least one pictogram which provides information on the temperature of the air outside the vehicle, as described below in connection with Figures 3-5.

[0027] According to a first step 301 of the method according to the invention, the device 100 according to the invention determines whether a press is made at the level of the first pictogram 3. To do this, it uses the tactile interaction detection functionalities of the screen 2. And when it establishes that such a situation occurs, the device 100 according to the invention proceeds by carrying out the following step of the method according to the invention described below.

[0028] According to a second step 302 of the method according to the invention, the device 100 according to the invention causes the display in the graphical interface of interactive and / or informative visual content according to the type of support which is carried out.

[0029] Thus, the device 100 according to the invention preferentially causes the display in the graphical interface of an interactive visual content if it establishes that a long press is made, as is schematically illustrated in [Fig.4]. Preferably, such content contains a first interactive zone 6 making it possible to activate or deactivate the display on the screen of the second pictogram 4, the one which provides information on a meteorological condition or risk, and a second interactive zone 7 making it possible to modify the unit of measurement used for the display of the air temperature outside the vehicle. The driver can thus control the temperature unit and the display of meteorological information with a simple long press of the finger at the level of the first pictogram 3.

[0030] Similarly, the device 100 according to the invention preferentially causes the display in the graphical interface of informative visual content if it establishes that a short press is made, as is schematically illustrated in [Fig. 5]. Preferably, such content explains a meteorological condition, a meteorological risk and / or a malfunction of a component for measuring the air temperature outside the vehicle (e.g. sensor, probe, connectors, etc.). The driver can thus become aware of elaborated meteorological information with a simple short press of the finger on the first pictogram 3.

[0031] Thus, thanks to the method and the device according to the invention described above, a more ergonomic alternative is provided for ergonomically controlling the provision of information about weather conditions and / or risks by means of a touch screen of a human-machine interface of a motor vehicle. The device and the method according to the invention also make it possible and easy to interaction with an indication of the outside air temperature displayed on a touch screen of a human-machine interface of a motor vehicle, in particular to modify a unit of measurement used. The invention therefore improves the ergonomics of human-machine interfaces of motor vehicles.
