Brief description of the figures
[0011] Other features and advantages of the invention will become apparent from an examination of the detailed description below, and the accompanying figures, in which:
[0012] [Fig-1] is a diagram of a motor vehicle according to the invention;
[0013] [Fig.2] is a functional diagram of a device according to the invention; and
[0014] [Fig.3] is a flowchart of the steps of a process according to the invention. Detailed description of the invention
[0015] Figure 1 schematically illustrates a motor vehicle 1 according to the invention. This is equipped with a human-machine interface 2, which includes at least one head-up display unit 3, which conventionally allows the display of visual content on a display surface located in the driver's field of vision when the driver is looking at the road in front of the vehicle 1, a first touchscreen 4 arranged in a first location near the driver's seat, so that the driver can easily perform touch interactions on its display surface when seated in the driver's seat, and a second touchscreen 5 arranged in a second location near the driver's seat, for example next to or below the first screen 4.
[0016] Advantageously, the vehicle 1 according to the invention also includes a device 100 for managing the operation of a human-machine interface of a motor vehicle, said human-machine interface comprising a head-up display device, a first touch screen arranged in a first location near the driver's seat and a second touch screen arranged in a second location near the driver's seat, as described below, which implements a method for managing the operation of a human-machine interface of a motor vehicle, said human-machine interface comprising a head-up display device, a first touch screen arranged in a first location near the driver's seat and a second touch screen arranged in a second location near the driver's seat, as briefly summarized below and described in detail below.
[0017] During the implementation of the method according to the invention, the device 100 according to the invention continuously monitors any touch interactions that are performed on the first screen 4 or on the second screen 5. And when it determines that a touch interaction consisting of a swipe is performed on the first screen 4 or the second screen 5, it then causes the transfer of content between the screens 4, 5 and the display surface of the head-up display unit 3. More specifically, when the touch interaction is an upward, vertical, or diagonal swipe, the device 100 according to the invention then causes the transfer of content The content displayed on the first screen 4 or the second screen 5, depending on which screen the interaction is performed, is transferred to the display surface of the head-up display 3. Conversely, when the interaction is a downward swipe, the device 100 according to the invention then transfers the content displayed on the display surface of the head-up display 3 to the first screen 4 or the second screen 5, depending on which screen the interaction is performed. In other words, the driver can, with a simple gesture, transfer visual content between a touchscreen and the head-up display 3, and vice versa. It is in this way that the device 100 according to the invention contributes to providing a more ergonomic and safer human-machine interface for a motor vehicle.
[0018] Figure 2 schematically illustrates the device 100 for managing the The operation of a human-machine interface for a motor vehicle, said human-machine interface comprising a head-up display, a first touchscreen arranged in a first location near the driver's seat, and a second touchscreen arranged in a second location near the driver's seat. It is essentially a computer device, comprising at least one information processing unit 101, including one or more processors, a data storage medium 102, on which is stored, in particular, a program comprising program code instructions for executing the steps of the process according to the invention described below, and an input and output interface 103 enabling the reception and transmission of data.
[0019] Preferably, the device 100 according to the invention is hosted on an independent computer and interacts via its input and output interface 103 and by means of a wired communication network of the vehicle (e.g. CAN, Ethernet, MOST) - represented on [Fig. 1] by a double-direction arrow - with the human-machine interface 2 of the vehicle 1, in particular with its head-up display equipment 3, its first screen 4 and its second screen 5. Alternatively, the device 100 according to the invention is part, in whole or in part, of the human-machine interface 2 of the vehicle 1.Therefore, the device 100 according to the invention can, in particular, determine whether a touch interaction consisting of a slide is performed on the first screen 4 or on the second screen 5, and it can cause the transfer of content displayed on the first screen 4 or on the second screen 5 to the display surface of the head-up display equipment 3, and vice versa.
[0020] According to the invention, all the elements described above contribute to enabling the implementation of a method for managing the operation of a human-machine interface of a motor vehicle, said human-machine interface comprising a head-up display unit, a first touchscreen arranged in a first location near the driver's seat and a second touchscreen arranged in a second location situated near the driver's seat, as described below in relation to [Fig.3].
[0021] Figure 3 illustrates, by means of a flowchart, the steps of the process according to the invention.
[0022] According to a first step 301 of the method according to the invention, the device 100 according to the invention determines whether a touch interaction, consisting of a swipe, preferably vertical, or alternatively diagonal, is performed on the first screen 4 or on the second screen 5. To do this, it interacts with the human-machine interface 2 or with its screens 4, 5. Thus, the device 100 according to the invention continuously monitors whether a swipe-type touch interaction, performed with one or more fingers, is performed on one of the screens 4, 5. In other words, it continuously monitors whether the driver expresses a desire to move content that is currently displayed on one of the screens 4, 5 to the display surface of the head-up display 3, or vice versa. And when it determines that such an interaction is performed, it then carries out the next step of the method according to the invention described below.
[0023] According to a second step 302 of the method according to the invention, when it establishes that the interaction is an upward slide, the device 100 according to the invention then causes the transfer of content displayed on the first screen 4 or on the second screen 5, depending on the screen on which the interaction is carried out, to the display surface of the head-up display unit 3. The driver can thus more easily view in front of him content that is originally displayed on one of the screens 4, 5. Conversely, when it establishes that the interaction is a downward slide, the device 100 according to the invention then causes the transfer of content displayed on the display surface of the head-up display unit 3 to the first screen 4 or the second screen 5, depending on the screen on which said interaction is carried out.The driver can thus easily free up the display area of the head-up display unit 3 from content that is no longer of interest by sending it back to one of the screens 4, 5 on which it was originally displayed.
[0024] Thus, thanks to the method and device according to the invention described above, a solution exists for providing a multi-screen human-machine interface that allows the driver to view content displayed on each screen of the human-machine interface more safely and ergonomically. In this way, the method and device according to the invention contribute to improving the ergonomics and safety of motor vehicles equipped with a multi-screen human-machine interface.
