    Selector of an automatic gearbox of a motor vehicle and method for selecting the autonomous driving mode
    The present invention relates to a selector of an automatic gearbox of a motor vehicle. The invention also relates to a method of selecting the autonomous driving mode implemented with such a selector.
    More and more car manufacturers are able to offer vehicles with an autonomous driving mode allowing the vehicle unmanned driving, in total or semi autonomy. These vehicles are equipped with radars, remote sensing by laser, cameras or other sensors, allowing the vehicle to circulate while managing external environmental elements, such as stop lights, pedestrians, other vehicles in motion or at a standstill or other obstacles.
    Developments are currently moving towards the possibility given to the driver in certain driving situations to use this mode of autonomous driving, especially on the highway or in case of urban traffic jams. Indeed, these driving situations are relatively simple to manage. The autonomous mode allows the driver to perform other tasks and avoid fatigue situations especially over long distances.
    However, it may be necessary that the selection of the autonomous mode may be prohibited in other driving situations.
    In addition, the autonomous driving mode can be activated and deactivated generally by one or more supports on one or two buttons located on the steering wheel of the motor vehicle, for example made by push buttons. In some embodiments, a first support allows the selection of the autonomous driving mode and a second longer support allows the validation.
    A disadvantage of this is that these means of activation / deactivation require space available on the steering wheel while it already incorporates many other features, such as switches horn, car radio, cruise control, the heating of the steering wheel and / or telephony means.

    Thus, by moving the selection of the autonomous driving mode to the selector of the automatic gearbox, the user chooses with a single selector all driving modes of the vehicle. The arrangement of the control member for selecting the control position of the autonomous driving mode at the selector of the automatic gearbox is thus more intuitive for the driver.

    In these figures, the identical elements bear the same reference numbers. The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.
    Figure 1 shows a selector 1 of an automatic gearbox 9 of a motor vehicle.
    The selector 1 comprises a control member 4. The control member 4 is movable and manipulable by the conductor 2. It is for example a rotary control knob, a pivoting lever or a linearly movable control slider.
    FIG. 1 represents an exemplary embodiment of a control member 4 made by a ring-shaped rotary control knob.
    The selector 1 is for example arranged at the level of the automatic gearbox 9 between the two front seats of the vehicle, to the right of the driver's seat and has several control positions such as: a parking mode P (or "Park" in English) for which the wheels of the vehicle are blocked, a reverse mode R (or "Reverse" in English) to activate the reverse, a neutral mode N (or "Neutral" in English) in which the wheels are unlocked, at least one forward mode D (or "Drive" in English) for which all speeds are possible, and an autonomous driving mode A. The control member 4 is configured to select a control position among these different control positions according to the will of the user 2, each control position being located on a displacement path that the control member 4 can browse.
    The autonomous driving mode A (or automatic or semi-automatic driving mode) allows the vehicle to drive unmanned, fully autonomous or semi-autonomous. For this, the vehicle comprises an autonomous driving system 5 connected for example to radar, laser remote sensing means, cameras or other sensors, allowing the vehicle to drive without pilot while managing the external environmental elements, such as as stop lights, pedestrians, other moving or stationary vehicles or other obstacles. The automatic transmission control unit 4 of certain vehicle models are also configured to assume a plurality of forward operating mode control positions D, such as a control position of a city driving mode 3 (only the three first speeds are used) or a control position of a low-speed driving mode S (for "Second" in English) (only the first two speeds are used for example in case of ice, snow, engine brake for steep slope to descend ...) or a control position of a very low-speed driving mode L (for "Low" in English) (maintains a low-speed line in case of ice, strong coast to climb. ..). Other models still provide a control position of a sporty driving mode S for which the gear changes are made for higher speeds and the downshift during braking is faster) or a control position of a winter driving mode W (for "Winter" in English) for which the first gear engaged is the second, which limits the risk of wheel spinning when starting on icy road.
    The different control positions that can be selected by the control member 4 are configured to be selected successively, along a travel path that can be traversed by the control member, one in place of the other, with a predefined ordered layout.
    Thus, by moving the selection of the autonomous driving mode A to the selector 1 of the automatic gearbox 9, the user 2 chooses with a single selector 1 all the driving modes of the vehicle. The arrangement of the control member 4 allowing the selection of the control position of the autonomous driving mode A at the selector 1 of the automatic gearbox 9 is thus more intuitive for the driver.
    Furthermore, the transition to autonomous driving mode A can then depend on the active control position of the automatic gearbox 9.
    In addition, this frees up space at the steering wheel.
    For example, and as can be seen in FIG. 1, the control position of the autonomous driving mode A is located at one end of the ordered arrangement, successively at the control position of the forward mode D, so that the position of control of the autonomous driving mode A can only be selected after the selection of the control position of a forward operating mode A.
    The predefined arrangement is for example then in order: the control position of the parking mode P, the control position of the reverse mode R, the control position of the neutral mode N, the control position of the mode forward movement D and the control position of the autonomous driving mode A.
    This ensures that the autonomous driving mode A can not be activated without the vehicle having previously switched to the forward mode D.
    According to an exemplary embodiment, the selector 1 comprises a programmable braking means of the control member 4 to oppose a resistance force to the user 2 moving the control member 4 according to a signal of a control unit 3.
    The resistance force opposed to the user 2 can then vary and be controlled by a processing unit 3 of the selector 1. It can thus control the intensity of the effort required by the user 2 to move the control member 4 by software, without this control being limited by mechanical constraints. In addition, it adds a feature preventing the authorization to switch to autonomous driving mode A in certain driving situations.
    Indeed, it can be provided that the selector 1 comprises a locking means of the control member 4 configured to block the movement of the control member 4 to the control position of the autonomous driving mode A according to a blocking signal of an autonomous driving system 5.
    The blocking signal of the autonomous driving system 5 is related to the road situation. It is sent to a processing unit 3 configured to control the blocking means.
    The autonomous driving system 5 is for example connected to the navigation device of the vehicle. For example, the movement of the control member 4 to the control position of the autonomous driving mode A is blocked when the vehicle is located on small roads or off-highway.
    In another example, the autonomous driving system 5 comprises sensors, such as cameras or radar, for evaluating the density of the car traffic to decide if the autonomous driving mode A is available or not.
    The locking means is for example mechanical, electrical or magnetic.
    In the case where the selector 1 comprises a programmable braking means of the control member 4, the locking means can be achieved by programming a resistance force to the user 2 moving the control member 4 important to the control position of the autonomous driving mode A, blocking the movement of the control member 4 to this control position.
    The selector 1 may comprise a force sensor 21 configured to measure a force exerted on the control member 4.
    In the case of a control member 4 made by a rotary control knob, the force sensor 21 comprises at least one torque sensor for measuring the torque exerted on the control member 4.
    The force sensor 21 makes it possible to measure the force exerted on the control member 4, for example by a piezoresistive, capacitive, resistive or any other technology known to a person skilled in the art for detecting a force variation, such as example of the strain gauges, etc ... The processing unit 3 is connected to the force sensor 21 and can be configured to control the programmable braking means to allow the displacement of the control member 4 to a position control selected by the driver 2, and control said selected control position to the automatic gearbox 9, when a force exerted on the control member 4 is greater than a predetermined force threshold beyond a threshold of predetermined duration.
    The selected control position is one of the control positions of the successive modes P, R, N, D, A which can be selected by the control member 4 in the predefined ordered arrangement. The processing unit 3 sends for example the information of the selected control position on the CAN 21 of the motor vehicle, also connected to the automatic gearbox 9 and the autonomous driving system 5.
    It can further be provided that the selector 1 comprises a light indicator 7 comprising progressive lighting means for progressively modifying the illumination of the indicator light 7 as a function of the duration of the exercise of the force on the organ 4 beyond the predetermined force threshold.
    The progressive lighting means comprise for example a set of LEDs, the LEDs lighting successively according to the duration of the exercise of the force on the control member 4. The indicator light 7 forms for example a light path, having a shape of a circle or line, whose lighting is gradually changed, the light path being completely modified at the end of the predetermined time. The modification of the lighting can be for example the progressive lighting of the light path or its gradual change of color.
    In the case of a control member 4 made by a rotary control knob, the indicator light 7 may be a ring at least partially surrounding the control member 4. The illumination of the periphery of the light ring 7 in a progressive manner over 360 ° when the force exerted on the control member 4 is greater than the predetermined force threshold.
    An unlit portion 7a of the indicator light 7 (FIG. 4b) or illuminated with a different color (FIG. 4d) corresponds to the time remaining before the change of position P, R, N, D, A is not allowed. The user 2 can thus see that his command has been taken into account. The animation of the display also allows it to estimate the time it remains to maintain the force exerted on the control member 4 to change the control position.
    The selector 1 may further comprise indicator lights, for example as many indicator lights as control positions that can be selected by the control member 4, configured to illuminate according to the control position selected by the organ order 4.
    The indicator lights have for example a letter shape, such as the letters P, R, D, N, A.
    It is also possible to associate a separate color for the indicator light indicating the control position of the autonomous driving mode A.
    An indicator light A may be configured to flash when the control position of the autonomous driving mode A is available.
    According to an example of embodiment better visible in FIG. 2, the selector 1 comprises a magneto-rheological fluid module 13 comprising: a magnetorheological fluid 17 in contact with a mobile element 16 of the control member 4, mobile in rotation (FIG. 2) or translation, a unit for applying a magnetic field 14, at least one coil 18 for applying a magnetic field to the magnetorheological fluid 17, the unit for applying a magnetic field 14 being configured to change the power supply of the coil 18 to modify a resistance force opposing the user 2 moving the movable member 16 of the control member 4. The control member 4 may comprise a gripping member 15 secured to the movable member 16, that is to say rigidly connected to the movable member 16. The gripping member 15 is for example made of material with the movable member 16 or clipped on the element mobile 16 or fixed by brush or by any other known fastening means. Alternatively, the gripping element 15 can be coupled to the movable element 16 via a gear system, chains, belts or any other mechanical means for ensuring a coupling between the gripping element 15 and the movable element 16.
    A haptic feedback is generated to the user who moves the movable member 16, for example via the gripping element 15, by modifying the magnetic field applied to the magnetorheological fluid 17. The term "haptic" refers to a return by the touch, such as a variable resistance force.
    Indeed, the magneto-rheological fluid 17 has the property that its viscosity varies under the effect of a variable magnetic field. Thus, the resistance force induced by the magnetorheological fluid 17 is low when no magnetic field is applied and becomes more and more important when the intensity of the magnetic field increases. Magnetorheological fluids can thus be used as magneto-rheological brakes. For example, the application of a niche-shaped intensity makes it possible to create hard points at indexing points for which the intensity is important.
    The magnetic field created by a coil 18 being proportional to the current flowing through it, it is possible to vary the intensity of the magnetic field created at the center of the coil 18 by varying the supply of the coil 18. The variation of the intensity the magnetic field applied to the magnetorheological fluid 17, makes it possible to vary the viscosity of the fluid, and thus the resistance force exerted by the fluid. It is thus possible to vary or modulate the force with which the mobile element 16 can be moved to generate a haptic feedback specific to the user 2 handling the mobile element 16.
    The magneto-rheological fluid module 13 may further comprise a position sensor 20, configured to measure the displacement position of the movable member 16, such as the angular position in the illustrated case of a rotating movable member 16. It may for example comprise an encoder, such as an optical encoder or a piezoelectric device. The position sensor may be located at different locations near the movable member 16.
    The torque sensor 21 may, for example, provide a signal, such as an output voltage, representative of the intensity of the force exerted on the mobile element 16. It may also, at the same time, provide a sense of rotation of the movable element 16.
    In the embodiment of Figure 3, the gripping member 15 is pivotally mounted relative to a ring 43 of the movable member 16, the pivoting of the gripping member 15 is blocked by two torque sensors 21 located between the gripping element 15 and the ring 43 of the movable element 16.
    Alternatively, a single torque sensor 21 can be used, for example by applying a preload to the sensor, the rotation of the gripping element 15 in one direction causing a detectable under stress while the rotation in the other direction causes a over-stress also detectable.
    According to the embodiment illustrated in FIG. 2, the magneto-rheological fluid module 13 comprises a base 19 having a generally cylindrical shape extending along an axis of rotation Z of the module 13, closed at one of its ends. by a fixed central axis 10 oriented along the axis of rotation Z, defining an annular cavity 11. The rotary element 16 is rotatably mounted on the base 19 fixed around the axis of rotation Z.
    The cavity 11 is intended to receive on the one hand the magnetorheological fluid 17 and on the other hand an end of the rotary element 16. The rotary element 16 is then partially immersed in the magneto-rheological fluid 17. base 19 also has an annular housing 12 which at least partially surrounds the cavity 11. The annular housing 12 receives one or more coil (s) 18 which, with its (their) feed (s) (not shown), form the unit for applying a magnetic field 14 to the magnetorheological fluid 17.
    The resistance force applied by the magnetorheological fluid 17 to the rotary member 16 varies depending on the fluid surface in contact with the rotary member 16. Thus, the end of the rotating member 16 in contact with the rotating member 16 magneto-rheological fluid 17 may comprise a plurality of cylindrical and concentric end walls 133 extending along the axis of rotation Z, and facing complementary walls extending from the bottom of the cavity 11. For example, base 9 comprises a complementary wall 144, which is interposed between the end walls 133 of the rotary element 16 to increase the facing surfaces between the rotary element 16 and the base 19 and thus increase the force torque that can be exerted on the rotating element 16 with a given power supply.
    The magnetorheological fluid module 13 further comprises seals 166, for example interposed on the one hand, between the cavity 11 and a cover 155 closing the cavity 11 and, on the other hand, between the cavity 11 and a shoulder of the rotating member 16. The seals 166 seal to prevent leakage of the magnetorheological fluid 17 out of the cavity 11. The cover 155 also comprises a housing receiving a bearing or ball bearing 177 which provides the connection in rotation between the base 19 and the rotary element 16.
    Different shapes or haptic feedback profiles can be obtained.
    For example, the intensity of the magnetic field may have a slot shape in which the intensity is zero or low except at the positions P, R, N, D, A where this intensity is strong so as to create a force of significant resistance.
    The processing of the signals from the position sensor 20 and the force sensor 21 is performed by the processing unit 3 which drives the application unit of a magnetic field 14, thus programming the braking means of the organ 4 to oppose a resistance force to the user 2 moving the control member 4.
    It can be provided that the unit for applying a magnetic field 14 is configured to lower the magnetic field applied to the magnetorheological fluid 17 when the force exerted on the control member 4 is greater than a force threshold predetermined beyond a threshold of predetermined duration, according to an exemplary embodiment of the programmable braking means.
    In addition, it can be provided that the unit for applying a magnetic field 14 is configured to increase the magnetic field applied to the magnetorheological fluid 17 so as to block the displacement of the control member 4 towards the position of control of the autonomous driving mode A according to the blocking signal of the autonomous driving system 5, according to an exemplary embodiment of the locking means of the control member 4.
    An example of operation will be described with reference to FIGS. 4a, 4b, 4c, 4d.
    It is first considered that the control member 4 of the automatic gearbox 9 selects the control position of the forward operating mode D (Figure 4a). The letter D is illuminated. The light ring 7 is off. In addition, the letter A flashes (for example of a different color than the letter D) to indicate to the driver that the road situation allows the passage to autonomous driving mode A.
    If the user 2 wishes to switch to autonomous driving mode A, he exerts a torque on the rotary control knob 4 towards the control position to reach.
    The intensity and / or the duration of the force exerted on the rotary control button 4 are measured.
    The movement of the rotary control knob 4 is blocked as long as the intensity and / or duration of the force exerted on the rotary control knob 4 has not reached a threshold of effort and / or of predefined duration. For this, the intensity of the magnetic field applied to the magnetorheological fluid 17 is important so as to create a resistance force blocking the mobility of the rotary control knob 4 which does not rotate.
    While the movement of the rotary control knob 4 is blocked, the progress of the duration of the exercise of the effort is displayed by a light signal. The periphery of the light ring 7 then lights up progressively, as a function of the duration during which the force is exerted on the rotary control knob 4, as long as the force exerted is greater than the predetermined force threshold. and until the time exceeds the predetermined duration threshold (Figure 4b).
    The color of the lighting of the light ring 7 in progress is for example the same as that of the letter A indicating the control position of the autonomous driving mode A.
    When the predetermined duration threshold is reached, the control position of the autonomous driving mode A is activated. The letter A is illuminated while the letter D goes out.
    In addition, it releases the movement of the rotary control knob 4 to the control position to be reached when the force threshold and / or predetermined duration is crossed. For this purpose, the unit for applying a magnetic field 14 lowers the magnetic field applied to the magnetorheological fluid 17, leaving the mobile element 16 to rotate (FIG. 4c).
    To return to the forward driving mode D, the user 2 for example exerts a torque in the opposite direction of rotation on the rotary control knob 4.
    On the other hand, in a general manner and similar to speed control commands, any intervention of the driver in the driving, for example a braking, a clutch, an action on the steering wheel or the accelerator automatically switches the selector 1 to mode D. By his voluntary action, the driver expresses his wish to abandon the autonomous driving mode A and take the vehicle in hand.
    In the same manner, the torque exerted is measured by the force sensor 21. The periphery of the light ring 7 then changes color progressively as long as the force exerted on the rotary control knob 4 is greater than the threshold of predetermined effort and until the time exceeds the threshold of predetermined duration (Figure 4d).
    When the predetermined duration threshold is reached, the control position of the autonomous driving mode A is deactivated and the control position of the forward operating mode D is selected.
    The letter D is illuminated while the letter A flashes (Figure 4a).
    In addition, with a programmable and rotary control member 4, it is not necessary that the user 2 reposition the control member 4 in its initial position.
