Definitions
- the present invention relates to a proprioceptive, immersive, adaptive and connected driving or steering unit, intended to generate proprioception effects in particular during acceleration, braking and cornering while driving a vehicle.
- document WO2018185658A1 discloses a proprioceptive unit comprising mechanical guide hoops making it possible to move a seat for a user along curved trajectories.
- It relates more particularly to a new dynamic unit capable of supporting any type of seat or cabin capable of receiving one or more drivers or pilots, and providing gravitational accelerations in a particularly effective, reliable and compact manner using particular combinations of displacements.
- a proprioceptive unit comprising a first structure carrying a seat or cabin oriented in a front/rear direction, a pivoting connection about a horizontal axis between the first structure and a second structure, the second structure being deformable according to the geometry of a deformable isosceles trapezium between said pivoting connection and a base of the second structure, and a guide means for moving the base along a forward/backward linear path on a support, a first actuator for controlling the displacement in pivoting of the first structure with respect to the second structure, a second actuator for controlling the deformation of the second structure, and a third actuator for controlling the movement in translation of the second structure relative to the support, and coordinated control means of the first, second and third actuators.
- the plant optionally includes the following additional characteristics, taken individually or in any combination that the person skilled in the art will apprehend as being technically compatible with each other:
- the isosceles trapezoid determining the deformation geometry of the second structure has a vertex whose length is between 60 and 85% of the length of the base, and side arms whose length is between 55 and 75% of the length from the base.
- the first actuator comprises a jack operating between points of the first structure and of the second structure remote from said pivoting connection.
- the second actuator comprises a jack operating between opposite regions of the deformable isosceles trapezium.
- the pivoting connection between the first and second structures is located at a location located lower than one region of the seat or cabin where the head of the user is intended to be located, and the coordinated control means are capable of controlling the first actuator and the third actuator such that horizontal displacement of said region is minimized.
- control unit also includes a device for displaying a virtual environment for a user installed in the seat or cabin.
- the display device comprises at least one screen attached to a movable support, and a device for controlling the movement of the display device according to the movement of the seat or cabin.
- control unit also includes a masking screen of the real environment around the control unit and the display device.
- a simulation system in particular driving simulation, is also proposed, comprising a proprioceptive unit as defined above, sensor means for detecting driving actions by a user installed in the unit, a display device for the user , and a control device responding to the signals supplied by the sensor means to control in a coordinated manner a dynamic scene represented by the display device and the movements of the plant using its actuators.
- Figs. 1A and 1B are respectively a side view and a front view of a proprioceptive unit according to the invention, in a neutral position,
- Figs. 2A-2B to 6A-6B are respectively side and front views of the plant of Figs. 1A and 1B, in positions displaced from the neutral position,
- Figs. 7A to 7H illustrate different postures of the unit for different commands at the level of two actuators of the unit
- Fig. 8 represents a superposition of different postures of the plant to show a certain geometric property.
- a proprioceptive, immersive, adaptive and connected control unit has been represented in an initial state or neutral position.
- the longitudinal X, transverse Y and vertical Z directions are illustrated in these figures.
- the control unit comprises an upper part 100 comprising a platform 110 carrying a driving position 120 comprising a seat 122 and control elements, here a block 124 comprising a steering wheel 125 and pedals 126. These elements are connected to appropriate sensors, known way.
- the upper part 100 is carried by a mobile intermediate structure 200 which forms in cross section a deformable isosceles trapezium 220, this structure comprising a connection 210 pivoting about an axis parallel to Y between an upper region 221 of the trapezium and the platform 110, while a jack 230 comprising a jack body 231 and a jack rod 232 operates between said upper region 221 and the platform 110, being connected thereto according to pivoting connections with axes parallel to the transverse axis Y, to control the pivoting of said platform 110 and therefore of the driving position 120 as will be seen in detail below.
- a mobile intermediate structure 200 which forms in cross section a deformable isosceles trapezium 220, this structure comprising a connection 210 pivoting about an axis parallel to Y between an upper region 221 of the trapezium and the platform 110, while a jack 230 comprising a jack body 231 and a jack rod 232 operates between said upper region 221 and the platform 110
- the two side arms of the trapezoid 220 are designated by the references 222 and 223 in Figure 1B. Its base is designated by the reference 224. It will be noted that the stability of the intermediate structure with respect to a rotation around the transverse horizontal axis is preferably obtained by providing two deformable trapezoids, respectively front and rear, designated by the references 220av and 220ar. The deformability of the trapezoids is obtained by pivoting links around respective axes oriented along the horizontal longitudinal axis X (axis perpendicular to the drawing of Fig. 1 B).
- the base 224 of the deformable trapezoid(s) is defined by a platform 230 of the intermediate structure, this platform carrying wheels 231 by which it can move with guidance on horizontal rails 310 carried by a fixed ground structure 300, the rails 310 being oriented in the front/rear or longitudinal direction X.
- the deformation of the trapezoid(s) is ensured here by a cylinder 240 comprising a cylinder body 241 and a cylinder rod 242, which cylinder operates between the region of a lower corner of the deformable trapezium 220 and the region of the opposite upper corner, in being attached to the trapezoid in these regions with the possibility of pivoting along an axis oriented along the X direction.
- the front-to-back movement of the structures 100 and 200 on the rails is ensured by a motor 250 or even a jack.
- the control unit includes a control unit which receives as input the signals picked up at the level of the pedals and the steering wheel (accelerations, braking and changes of direction), in order, on the one hand, to control the progress of a performance in virtual reality either in a helmet virtual reality, either on one or more display screens surrounding the user in an immersive way, and on the other hand to control the movements of the driving position 120 by controlling the cylinders 230, 240 and the motor 250 to apply to the body of the user the corresponding accelerations and orientations.
- the jacks 230, 240 and the motor (or jack) 250 are of the electric type.
- FIGS 2A, 2B to 6A, 6B show the control unit with different positions of the driving position 120.
- the jack 240 has been actuated to lean the driving position to the left (relative to the direction of driving), which will generate for the user a lateral force to the left; this typically corresponds to the force experienced during a turn to the right; this effect is typically adjustable depending on the curvature of the turn and the speed at which it is taken.
- the driving position 120 with the aid of the cylinder 230 is inclined so that the user is leaning forward, thus applying to the latter a force corresponding to that of braking.
- the inclination varies in function of the braking force, and this effect can be combined with a displacement of the unit on the rails 310 using the motor 250, in particular if a frontal impact effect is desired.
- Figs. 5A and 5B illustrate the inclination of the driving position 120 in the opposite direction, corresponding to a situation of acceleration of the vehicle, the inclination being controlled to be all the greater as strong acceleration is simulated.
- movement along rails 310 can be applied by motor 250 to simulate a rear impact.
- Figures 6A and 6B illustrate the case of braking in a bend, the driving position 120 being both leaned forwards and to the right, thanks to a combination of the actions of the cylinders 230 and 240.
- the use of the deformation of an isosceles trapezoid makes it possible to prevent the user's head from crossing the axis of rotation of the seat at the initialization of the movement, this so that it resists the centrifugal force produced by this inclination.
- the design of these trapezoids responds to achieve this result with relatively precise choices of the respective lengths of the base, the top and the side arms. In a particular example, these dimensions are 60 cm for the base, 50 cm for the top and 35 cm for the side arms. More generally, a length of between 60 and 85% of the length of the base is adopted for the top, and for the side arms a length of between 55 and 75% of the length of the base.
- the seat while moving concomitantly, only pivots relative to its axis in the direction Y with masses balanced on either side, which makes it possible to limit the need for power of the two cylinders;
- the position of the head is identified using sensors, for example external sensors fitted to a virtual reality helmet (sensors fitted in particular to a helmet commercially manufactured by HTC Company, Taipei, known as "Vive Pro", or again of any appropriate sensor in the case of images projected on screens, this position being used as a reference position for controlling the movements of the seat
- the control unit systematically and automatically compensates for the longitudinal displacement of the head procured by the rotation of the seat by performing an opposite displacement of the same value using the motor 250 along the rails 310, so in that it essentially does not advance or retreat (it only goes up or down with the body according to a straight line or a slight arc of a circle, as illustrated in Figs. 7A to 7H). It is this kinematics with tilting of the body that makes it possible to provide gravitational decelerations, even to the strongest, without feeling the major parasitic effect of the recoil of the pelvis or the kidneys that one feels with a movement of failover not corrected in this way.
- Figs. 7A to 7H show for different settings of the jack 230 and the motor (or jack) 250, the distance taken horizontally between the head and the pivoting link 210, and the way in which the upper body moves tangentially to an arc of a circle vertical.
- the setback distance of the seat relative to its axis of rotation 210 preferably of the order of 550 to 600 mm depending on the size and position of the user, makes it possible to provide without parasitic effect, by simple rotation at the level of the pivoting connection 210 between the structures 100 and 200, an upward or downward acceleration creating a very realistic lifting and falling effect of the seat in the event of the vehicle taking off due to a speed bump or crossing a speed bump, d a median or sidewalk curb.
- Figs. 7A (neutral position) and 7B to 7F show that by tilting the structure 100 forward from different angles while moving back all of the structures 100 and 200 from corresponding determined distances, the user's head (here more precisely the headrest of the seat 122) does not undergo any component of horizontal displacement, whereas different braking intensities are simulated (different tilting angles of the structure 100).
- Figs. 7G and 7H show the same effect for two tilts of the 100 structure backwards, simulating two levels of acceleration without the user's head experiencing substantial horizontal displacement.
- N panoramic display screens typically three screens
- suitable inclinations typically three screens
- the control unit incorporates a telescopic arm with movements controlled in synchronism with those of the driving position and supporting the screens, this arm being mounted on a fixed support, for example on the ceiling of a room in which is installed the central.
- the support structure of the screens then advantageously incorporates a veil pivoting at its two ends on its horizontal axis so as to conceal, for the various possible positions of the seat, the visual space corresponding to the terrestrial reference, and to avoid the effects of nausea for the driver.
- the arm When stationary, the arm can advantageously be deployed in the "lecturer" position to project the driving routes of the students in turn during the feedback and discussion sessions by the educator, with the veil in the anti-reflective position and acting as a sound box above the screens.
