Description

Title of the invention: Method for controlling a screen actuator of a motor vehicle, associated device and motor vehicle.

[0001] The invention relates to the control of an actuator, for moving an element of a motor vehicle, the element being a screen of a passenger compartment of the motor vehicle.

[0002] There is a need to make such control easier and more intuitive.

[0003] For this purpose, the invention relates to a control method (of movement), the method being characterized in that it comprises the following first steps: • Detection of a first movement of a mobile telephone, from a first position of the mobile telephone, then • Determination (in other words: definition or calculation) of a second movement of an element, relative to a motor vehicle (in other words: in a reference frame located in the motor vehicle, for example in the dashboard of the motor vehicle) comprising an actuator (of the element), from a second position, from the first movement, the element being located in a passenger compartment of the motor vehicle then • Sending to the actuator an instruction commanding the actuator to move the element in such a way as to make the element perform the second movement (in other words: an instruction for the actuator to implement the second movement), The element being a second display screen (external to the mobile phone) of a dashboard of the motor vehicle (located for example in the passenger compartment).

[0004] Thus, the invention allows, in a simple and intuitive manner, a driver or a person to control a second movement of the second screen, from a first movement of the mobile telephone.

[0005] The second movement may be determined and / or the instruction may be sent (, by the microprocessor), to the actuator, while the first movement is being detected or after the first movement has been detected.

[0006] The second movement can be determined, and the instruction can be sent (by the microprocessor) to the actuator as the microprocessor detects the first movement. Thus, the second movement can be performed as the first movement is performed.

[0007] The determination of the second movement can be implemented by executing a function, the second movement being an image of the first movement by the function. The function can be implemented by a program computer and / or an integrated circuit. Of course, a large number and variety of functions are possible.

[0008] The method may comprise a step of moving the element by the actuator, upon receipt of the instruction.

[0009] For example, the actuator moves the element, upon receipt of the instruction, by means of an electric motor, a hydraulic cylinder, or electromagnetic means.

[0010] Sending the instruction may be implemented by radio frequency communication or wired communication.

[0011] The mobile telephone may be inside the motor vehicle or the passenger compartment, or outside, and for example in the immediate vicinity, of the motor vehicle or the passenger compartment.

[0012] The first movement may be, for example, in a terrestrial frame of reference or a frame of reference of the motor vehicle (in other words: the first movement may be, for example, relative to the earth or to the motor vehicle).

[0013] Technologies for detecting the first movement of the mobile telephone, in a terrestrial reference frame, are used routinely. The detection of the first movement can be carried out in a manner known to those skilled in the art, from data coming from movement sensors of the mobile telephone (and the method can comprise a step of receiving this data). These sensors can comprise, in a non-limiting manner, an accelerometer, a gyrometer, a magnetometer, an orientation sensor and / or a linear acceleration sensor.

[0014] The first movement, if it is initially obtained in a terrestrial reference frame, can be transferred (in other words: transformed), during the step of determining the first movement, into a reference frame of the motor vehicle from the movements of the motor vehicle (determined from a satellite location module of the motor vehicle, for example called “GPS”, and / or a magnetometer and / or an accelerometer and / or a gyroscope of the motor vehicle) in this terrestrial reference frame.

[0015] Alternatively, the detection of the first movement is carried out in a reference frame of the motor vehicle, for example: • By radiofrequency triangulation of the mobile phone in the passenger compartment (or elements of the mobile phone to detect rotations), • From images from a camera of the motor vehicle filming, for example, the interior of the passenger compartment and / or the environment of the motor vehicle.

[0016] Conversely, the first movement, if it is initially determined in a reference frame of the motor vehicle, can be transferred (in other words: transformed) into a terrestrial reference frame, from the movements of the vehicle in this reference frame terrestrial.

[0017] The first movement is for example applied to the mobile telephone by a person, holding (in other words: carrying) the mobile telephone, for example present in the passenger compartment or in the immediate vicinity of the motor vehicle or the passenger compartment (and the method may comprise an application (or, in other words: an implementation) of the first movement by the person).

[0018] According to one embodiment, the first movement comprises a first rotation of the mobile telephone around a first axis of rotation.

[0019] The first movement may also or only include, as a variant, a translation.

[0020] According to a first variant: • The first axis of rotation is horizontal (in other words: parallel to the Earth's surface), • The mobile phone comprises a first display screen comprising a first planar display surface, and the first axis of rotation is parallel to the first planar display surface, in the first position.

[0021] According to a second variant, the first axis of rotation is perpendicular to the first flat display surface, in the first position.

[0022] According to a third variant, the first axis of rotation is vertical,

[0023] According to other variants, the axis of rotation can be oriented in other directions.

[0024] For example, the first axis of rotation is in a central area of ​​the mobile phone (in the first position). Alternatively, it is in a peripheral area of ​​the phone or outside the mobile phone (in the first position).

[0025] According to one embodiment, the second movement is a second rotation of the second screen around a second axis of rotation.

[0026] Alternatively (or additionally), the second movement may comprise a translation.

[0027] In a first exemplary embodiment, for example, according to the first variant (in a non-limiting manner, because, for example, the second variant is also possible) • The second axis of rotation is horizontal, when the motor vehicle is parked (or driven) on a horizontal roadway (in other words: the passenger compartment includes a floor, the second axis is parallel to the floor), and • The second display screen comprises a second planar display surface and the second axis of rotation is parallel to the second planar display surface (in the second position).

[0028] According to a second exemplary embodiment, for example (in a non-limiting manner) according to the second variant: • The second axis is horizontal, when the motor vehicle is parked (or circulates) on a horizontal roadway (in other words: the second axis is parallel to the floor), and • The second axis is perpendicular to the second flat display surface (in the second position).

[0029] According to a third exemplary embodiment, for example (in a non-limiting manner) according to the third variant: • The second axis is vertical, when the motor vehicle is parked (or driven) on a horizontal roadway (in other words: is perpendicular to the floor).

[0030] Of course, the second axis can have other directions, regardless of the orientation of the first axis.

[0031] According to one embodiment, the first display screen comprising a first high point, the first high point being the highest point of the first display screen relative to the earth's surface (in other words: relative to the ground), in the first position, and the second display screen (or the second flat display surface) comprising a second high point, the second high point being the highest point of the second display screen relative to a floor of the passenger compartment, in the second position, during the step of determining the second movement, the second movement is determined so that: • If the first high point moves away from the Earth's surface during the first movement, then the second high point moves away from the floor of the cabin during the second movement, • If the first high point approaches the earth's surface during the first movement, then the second high point approaches the floor of the cabin during the second movement.

[0032] Thus, the direction of the second rotation can be determined from the direction of the first rotation. More generally, the direction of the second movement can be determined from the direction of the first movement.

[0033] The direction of the second rotation can be determined in the same way as in the first embodiment, from the direction of the first rotation in the second or third embodiment.

[0034] Alternatively, the direction of the second rotation may be invariable (for example, if the second screen can perform rotations of 360 degrees or more).

[0035] Furthermore, an angle of the second rotation may be proportional, for example equal, (alternatively, constant or random) to an angle of the first rotation. More generally, an amplitude of the second movement may be proportional or equal (alternatively, constant or random) to an amplitude of the first movement.

[0036] The same can be true for an angular speed (or acceleration) of the second rotation (or more generally, for a speed or acceleration of the second movement).

[0037] According to one embodiment, the method may further comprise the following steps: • Detection of an action via a human-machine interface (for example, by a touch on the first display screen, (in other words: by a touch on the first flat display surface) or the second display screen, or even, a third movement of the mobile phone), then • On detection of the action: • Determination of the first position (which can be implemented in the same way and / or with the same means as the determination of the first movement), then • Implementation of the first steps.

[0038] Alternatively, the first steps can be implemented without steps of detecting an action on a human-machine interface, for example upon detection of a significant change in the lighting conditions of the passenger compartment (for example between night and day traffic), when the screen is about to display information of a predetermined nature (for example, a cinematographic work), or when the vehicle detects a new driver.

[0039] Generally speaking, the method according to the invention may comprise a step of determining (in other words: a step of detecting) the first position, prior to the step of detecting the first movement.

[0040] Alternatively, the telephone is placed in the first position, prior to the step of detecting the first movement, for example in a support of the vehicle, without the step of determining the first position being implemented.

[0041] Generally speaking, the method according to the invention can obviously comprise a step of determining the second position, prior to the step of detecting the first movement. This second position is for example known (in other words: in memory) by the actuator.

[0042] The invention also relates to a computer program comprising instructions executable by a microprocessor or a microcontroller or a computer, to implement the steps of the method according to the invention, when it is executed by the microprocessor or the microcontroller or the computer.

[0043] The method according to the invention can be implemented by an electronic device. The invention therefore also relates to an electronic device configured to implement the steps of the method according to the invention, as well as a first mobile telephone comprising the electronic device, the mobile telephone being the first mobile telephone.

[0044] The invention also relates to a motor vehicle comprising the electronic device according to the invention.

[0045] In this embodiment, the motor vehicle can receive, for example, data acquired by a movement sensor of the mobile telephone, from the mobile telephone, and detect the first movement from this data.

[0046] The characteristics and advantages of the computer program, the electronic device, the mobile telephone and / or the motor vehicle are identical to those of the method according to the invention (without it being necessary to repeat them here).

[0047] When the electronic device, mobile phone or motor vehicle, or other element, is "configured to" (or "capable of") performing or implementing a step or operation, this implies, for example, that the element comprises means for performing the step or operation. The means preferably comprise electronic means, for example a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor and / or a microcontroller.

[0048] For example, the electronic device comprises for example a microprocessor and / or a microcontroller and / or the computer program capable of being executed by the microprocessor and / or the microcontroller.

[0049] Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description which follows, comprising embodiments of the invention given as non-limiting examples and illustrated by the appended drawings, in which: • [Fig.l] represents an electronic device, a mobile telephone and a motor vehicle, according to an embodiment of the invention, • [Fig.2] shows the mobile phone in [Fig.l] in more detail than in [Fig.l], • [Fig.3] represents the screen, as well as axes of rotation of the screen which can be implemented during the implementation of the method according to the invention represented [Fig.4], • [Fig.4] represents an implementation of the method according to the invention, according to a example of realization, by the electronic device of [Fig.2],

[0050] In Figures 1 and 2, certain elements are, of course, seen through transparency.

[0051] Detailed description of an exemplary embodiment of the invention, with reference to Figures 1 to 4.

[0052] [Fig.l] and 2, a driver (not shown) present in the motor vehicle 200, holds in his hands a mobile telephone 100.

[0053] The mobile telephone 100 comprises a microprocessor 110 and motion sensors 120.

[0054] With reference to [Fig.4], in step S00, the microprocessor 110 detects a touch on the display screen 130 of the mobile telephone 100, in other words on the surface S130 of the display screen 130.

[0055] Upon detection of the action, the microprocessor 110 implements the following steps S10 to S50.

[0056] The microprocessor 110 determines, in step S10, the position of the telephone 100 represented [Fig.2] from data coming from the motion sensors 120.

[0057] In step S20, the microprocessor 110 detects a first rotation of the mobile telephone 100 along the axis atangl, in the direction asensl, for example 45 degrees, from the data coming from the movement sensors 120.

[0058] In step S30, the microprocessor 110 determines a second rotation of a screen 230 around the axis atang2 in the direction asens2, for example also 45 degrees. The axis atang2 is parallel to the floor of the passenger compartment 210 of the motor vehicle 200 and parallel to the flat display surface S230 of the screen 230 of the mobile telephone 100.

[0059] The screen 230 is part of the dashboard 220 and is located in the passenger compartment 210 of the motor vehicle 200. The motor vehicle 240 also comprises an actuator 240 of the screen 230.

[0060] In step S40, the microprocessor 110 sends, to the actuator 240, an instruction commanding the actuator 240 to move the screen 230 so as to make the screen 230 perform the second movement.

[0061] In step S50, the actuator 240 moves the screen 230 so as to carry out the second movement.

[0062] Thus, during the first movement, the high point 132 of the screen 130 approaches the earth's surface, and during the second movement, the high point 232 of the screen 230 approaches the floor of the passenger compartment 210.

[0063] Alternatively, the second movement may be determined and the instruction may be sent by the microprocessor 110 to the actuator 240 as the microprocessor 110 detects the first movement. Thus, the second movement may be performed as the first movement is performed.

[0064] According to a variant, the axis atangl is replaced by the axis aroull, and the axis atang2 is replaced by the axis aroul2. The position of the actuator 240 can then of course be different.

[0065] According to another variant, the atangl axis is replaced by the alacl axis, and the atang2 axis is replaced by the alac2 axis.

[0066] Alternatively, the microprocessor 110 may be included in the motor vehicle 200 and may receive the data from the movement sensors 120 via a radio frequency link, for example of the “Bluetooth” type.
