    Steering wheel for autonomous motor vehicle.
    The invention relates to a steering wheel for an autonomous motor vehicle.
    An autonomous motor vehicle is a vehicle that can roll, steer and adapt to road traffic, without driver intervention.
    When such a motor vehicle operates independently, the passenger installed in the driver's seat remains free to regain control of the vehicle. He can in particular regain control of the motor vehicle by actuating the steering wheel.
    However, when he does not wish to control the vehicle, the driver then generally adopts a resting posture, which differs significantly from his driving posture. In the resting position, the driver is frequently more comfortable in the driver's seat. His head then rests on the headrest and his bust is generally lower than when he is driving.
    This is why when the driver of an autonomous motor vehicle is in a resting posture, his point of view on the dashboard of the vehicle is modified compared to the driving posture.
    The steering wheel can then partially obstruct the driver's field of vision, in particular when he wishes to read information displayed on the display screen installed behind the steering wheel, which is known by the English term cluster, or close to the lower part of the windshield, in particular with head-up displays, known under the English term of Head-Up Display, more generally abbreviated as HUD.
    To overcome this problem, there is in particular known a retractable steering wheel capable of passing from a driving position, in which the driver can actuate it to steer the vehicle, to a retracted position in which the steering wheel is fully embedded in the dashboard. , so as to free the driver's field of vision.
    However, this type of steering wheel does not ensure optimum safety for the driver, because when the steering wheel is in the retracted position, the driver cannot regain control of the vehicle instantly, for example during a driving situation. emergency.
    There is also known a steering wheel having a main portion in an arc, in particular in the shape of a C, defining two free ends and a complementary portion in an arc itself separated into two sub arcs capable of being retracted by being inserted in translation at the interior of the C portion, respectively by the two free ends. When the vehicle is in autonomous operation, the driver can then retract the second arc portion, which corresponds substantially to an upper arc of the steering wheel when it is mounted in the passenger compartment, so that it can read the information displayed on the dashboard at the rear of the steering wheel.
    However, such a solution requires a relatively complex mechanical design of the steering wheel so that the arc portion can be inserted and come out in the C portion.
    Also, there is the need for a simpler steering wheel, which can be adapted so as not to obstruct the driver's vision when the latter is in a resting position, while allowing instant recovery.
    To this end, there is provided a steering wheel for a motor vehicle, comprising a hub defining an axis of rotation, a main portion substantially in an arc integral with the hub and a complementary portion in an arc integral with said main portion.
    Said complementary arc portion has two opposite ends each mounted for rotation on said main arc portion, substantially diametrically opposite.
    Thus, a relatively simple structure is obtained by which it is possible to retract half of the steering wheel, in particular the upper part of the steering wheel when it is mounted in the passenger compartment of the motor vehicle, in order to visually release the 'upper space, while maintaining the lower portion in a driving position allowing rapid recovery of the steering wheel.
    Advantageously and in a nonlimiting manner, said main portion defines two free ends, said two opposite ends being mounted for rotation respectively at said two free ends so as to be able to pivot said complementary portion in an arc from a driving position in which the main in arc and the complementary arc portion define a substantially toroidal convex shape, towards a retracted position in which the complementary arc portion is pivoted by at least 90 ° relative to the driving position, for example by a value between 90 ° and 180 °.
    Thus, it is possible to articulate the complementary portion relatively simply with respect to the main portion. In particular, the rotation can be carried out towards the rear of the motor vehicle, when the steering wheel is mounted in the passenger compartment, which has the effect of lowering the additional portion by bringing it closer to the driver. Thus the rotation can be relatively greater than if it were carried out towards the dashboard, and the driver can more simply handle the additional portion, even in the retracted position.
    In particular, said complementary arc portion has a length substantially equal to said main portion.
    In particular, the complementary and main portions each have an arc length greater than half the perimeter of the steering wheel so that their respective ends overlap.
    Advantageously and in a nonlimiting manner, the steering wheel comprises means for returning the complementary portion to the driving position. Thus, it is possible to allow an automatic return from the retracted position to the driving position, which simplifies the recovery of the steering wheel by the car driver.
    Advantageously and in a nonlimiting manner, said return means comprise a return spring. This provides a robust and inexpensive means of recall.
    Advantageously and in a nonlimiting manner, said return spring is integral on the one hand with the main portion and on the other hand with the complementary arc portion. Thus, the mounting of the return spring on the steering wheel is relatively simple to perform.
    Advantageously and in a nonlimiting manner, the steering wheel comprises two diametrically opposite spokes each extending between the hub and the main arc portion, said complementary arc portion was rotatably mounted on the main portion in the vicinity of said two spokes.
    Said spokes can be obtained in one piece with the main portion.
    In particular, the return spring can be installed in a radius among the two opposite radii.
    Advantageously and without limitation, said main portion has a closed part joining the two diametrically opposite spokes and two free ends each extending from said closed part opposite the diametrically opposite spokes. The two free ends thus form protruding parts, when the steering wheel is in the retracted position, which simplifies the instant recovery of the steering wheel by the driver when necessary.
    Advantageously and in a nonlimiting manner, the steering wheel comprises blocking means able to block the complementary portion in an arc in the driving position. Thus, driving safety is increased by preventing accidental passage of the additional arc portion towards the retracted position, for example when the driver actuates the steering wheel to drive the motor vehicle.
    Advantageously and in a nonlimiting manner, the blocking means comprise at least one push button installed on the complementary arc portion. Thus, the complementary arc portion can be unlocked, in order to be retracted, by pressing a push button located on the complementary arc portion, which allows a simple unlocking for the driver.
    Advantageously and in a nonlimiting manner, the steering wheel comprises locking means able to maintain the complementary portion in the retracted position. Thus when the steering wheel is in the retracted position the additional portion can be fixedly held so as not to interfere with the driver in its rest position.
    Advantageously and in a nonlimiting manner, the steering wheel comprises unlocking means capable of authorizing the passage of the steering wheel from the retracted position to the driving position.
    In other words, the unlocking means make it possible to release the complementary portion fixedly held by the locking means so that it can return to the driving position.
    The invention also relates to a motor vehicle comprising a steering wheel 5 as described above.
    Other particularities and advantages of the invention will emerge on reading the description given below of a particular embodiment of the invention, given by way of indication but not limitation, with reference to the appended drawings in which:
    to - Figure 1 is a front view of a steering wheel in a driving position according to a first embodiment of the invention;
    - Figure 2 is a front view of a steering wheel in a retracted position according to the embodiment of Figure 1;
    - Figure 3 is a detail view of the junction between the complementary arc portion 15 and the main arc portion of the embodiment of Figure 1;
    - Figures 4a and 4b shows a detailed view of the locking means of the steering wheel according to the embodiment of Figure 1;
    - Figure 5 is a front view of a steering wheel in a driving position 20 according to a second embodiment of the invention;
    - Figure 6 is a front view of a steering wheel in a retracted position according to the embodiment of Figure 5.
    According to a first embodiment, with reference to FIGS. 1, 2, 3, 4a and 4b, a steering wheel 1 comprises a hub 2, a main arc portion 3, also called main portion 3, integral with the hub 2, and an additional arc portion 4.
    The main portion 3 is secured to the hub 2 by two spokes 5.5 ′ diametrically opposite with respect to the hub 2, and by a third spoke 5 ”oriented substantially perpendicular to the first two spokes 5’, 5 ”.
    The spokes 5, 5 ’, 5” are obtained in one piece with the main portion 3.
    The main portion 3 has a closed portion 30 joining the two spokes 5, 5 'diametrically opposite and two free ends 31, 32 each extending from said closed portion 30 opposite the spokes 5, 5' diametrically opposite. In other words the closed part 30 and the two diametrically opposite spokes 5, 5 ′ define substantially a closed half-flywheel, while the two free ends 31, 32 each extend opposite a radius 5, 5 ′ diametrically opposite with respect to the closed part 30, so as to define two ends which can be grasped by the conductor.
    When the steering wheel 1 is mounted in the passenger compartment of a motor vehicle, the closed part 30 corresponds to the lower part of the steering wheel, while the two free ends 31, 32 extend upwards, beyond the spokes 5 , 5 'diametrically opposite.
    îo The complementary arc portion 4, also called complementary portion 4, comprises two opposite ends 4a, 4b mounted for rotation on the main portion 3.
    The opposite ends 4a, 4b are each mounted in the vicinity of a radius 5, 5 ’from the two diametrically opposed rays 5, 5’.
    The complementary arc portion 4 is then able to pass from a first position, called the driving position, represented in FIG. 1, in which position in which the main arc 3 and the complementary arc portion 4 define a substantially toroidal convex shape, towards a second position, called the retracted position, shown in FIG. 2, in which the complementary arc portion 4 is brought closer to the closed part 30 of the main arc portion 3.
    The transition from the driving position to the retracted position corresponding to a rotation of the complementary portion 4 of at least 90 °, in particular of a value between 150 ° and 180 °, for example a rotation of 180 °.
    Also in the retracted position, after a rotation of 180 °, the complementary portion 4 extends in the same plane as the main portion 3. In other words, in the retracted position, the complementary portion 4 surrounds the main portion 3.
    The rotation between the driving position and the retracted position is carried out firstly in the direction of the driver of the motor vehicle, in other words, from the front to the rear of the motor vehicle, so that the complementary portion 4 is distant from the dashboard.
    When the steering wheel 1 is in the driving position, as shown in FIG. 1, locking means prohibits rotation towards the retracted position, as shown in FIG. 2.
    In this embodiment, the locking means 40, 40 ', as shown in Figure 4a and 4b, include a push button 40, 40' associated with each opposite end 4a, 4b of the complementary portion 4. In other words the means locking 40, 40 'include two push buttons 40, 40'.
    Each push button 40, 40 'is mounted on the complementary portion 4, so as to be able to pass from a rest position, with reference to FIG. 4a, in which it protrudes from the complementary portion 4a, 4b, towards a position reentry, with reference to FIG. 4b, in which the push button 40, 40 ′ has entered the thickness of the complementary portion 4.
    When the steering wheel 1 is in the driving position, the push button 40, 40 'in its rest position forms an abutment against a free end 31, 32 of the main portion 3. Thus the push button 40.40' maintains the complementary portion 4 in the driving position.
    Once the push button 40, 40 ’is in its retracted position, it remains engaged therein so that the complementary portion 4 can be freely pivoted towards the retracted position.
    In the retracted position, the push button 40, 40 ’, is therefore kept retracted into the complementary portion 4, but when the rotation of 180 ° is carried out, it comes into contact with the main portion 3, as shown in FIG.
    2.
    When the complementary portion 4 reaches the retracted position, it can be maintained by a locking member, preventing it from pivoting freely. For example, a push button lock (type "push-pull" in English). In the retracted position, the steering wheel is locked in the zone 4a, 4b by a system of valves. For unlocking, the additional portion 4 is pushed towards the front of the vehicle. The valves unlock during this low amplitude rotational movement. The return spring then makes it possible to return the complementary portion 4 to its driving position.
    According to a second embodiment of the invention, with reference to Figures 5 and 6, the locking means 50, 50 'of the complementary portion 4 comprise at least one lug 50, 50', here two lugs 50, 50 'forming projection of the additional portion 4.
    When the steering wheel 1 is in the driving position, each lug 50, 50 ’forms a stop against a free end 31, 32 of the main portion 3. Thus the lugs 50, 50’ hold the complementary portion 4 in the driving position.
    When the complementary portion 4 is pivoted towards the retracted position, the lugs 50, 50 'come into abutment against the main portion 3, as shown in FIG. 6.
    Also, the rotation of the complementary portion is carried out on a rotation of between 90 ° and 175 °, for example between 160 ° and 170 °, in particular of a rotation of 162 °.
    According to an alternative embodiment of the invention, which can in particular be based on the first or the second embodiment of the invention, the flywheel 1 also comprises return means, not shown, here a return spring, by example a helical spring, for example a torsion spring, installed at one end on the main portion 3 or on a spoke 5, 5 'from the diametrically opposite spokes 5, 5' and on the other hand to the complementary portion 4 so that it is capable of automatically returning from the retracted position to the driving position.
    The return means may also include a return spring with radius 5, 5 diam diametrically opposite so that the return is exerted on each opposite end 4a, 4b of the complementary portion 4.
    For this alternative embodiment, an unlocking member, for example a push button, or an electric control, not shown, makes it possible to unlock the blocking of the complementary portion 4 in the retracted position so as to allow the recall of the complementary portion 4 by the return spring from the retracted position to the driving position.
