    [0001] TECHNICAL FIELD The invention relates to the field of driving assistance and in particular to cameras installed on certain vehicles. More particularly, the invention relates to a device for cleaning such a camera so that the quality of the driver assistance information provided to the driver is optimal. Some motor vehicles are now equipped with shooting means, particularly camera, to help the driver including in his parking maneuvers and / or back. It is understood that the information provided to the driver by these means of shooting is all the more useful when the image acquired is clear. The present invention is in this context and its purpose is to provide a device for cleaning cameras that is particularly effective.
    [0002] For this purpose, the subject of the invention is a device for cleaning a camera lens of a motor vehicle by means of a cleaning head, characterized in that it comprises means for driving the camera or the cleaning head, adapted to generate a relative longitudinal displacement of the cleaning head relative to the camera between a passive position in which the cleaning head is disposed outside the camera's field of view and a position active in which the cleaning head extends facing the lens to allow the ejection of cleaning liquid towards said lens. In a preferred embodiment of the invention, it is provided that the cleaning head or the camera moves relative to each other in a longitudinal direction, that is, substantially the same. optical axis of the camera. The drive means are arranged to effect a relative longitudinal displacement of the cleaning head relative to the camera, so that in the passive position, the cleaning head is longitudinally upstream of the lens 3027008 WFR2115 2 while in the the active position, the head is longitudinally remote from the camera, downstream of the lens. Here, "downstream" and "upstream" are defined positions defined with respect to the optical axis of the camera and with respect to the direction of the shooting.
    [0003] When the camera is a rear view camera, disposed at the rear of the vehicle and rotated to film a road scene behind the vehicle, the term "downstream" means that the head is positioned closer to the vehicle. the rear of the vehicle as the camera, and it is understood that if the camera was disposed at the front of the vehicle, the term "downstream" would mean that the head is positioned closer to the front of the vehicle than the camera. According to various features of the invention, taken alone or in combination: the camera comprises an objective at the end of which said lens is disposed, and the cleaning head has a shape complementary to said objective so as to be arranged around the objective in said passive position; the cleaning head has an axis which coincides with an axis of the objective and the lens; the lens of the camera has a circular section and the cleaning head has an annular shape of dimensions able to overlap around the lens; a liquid supply pipe connected to the cleaning head is provided, which further comprises an inner face provided with a plurality of nozzles through which the cleaning liquid is able to exit the head towards the lens in the active position; The inner face is inclined with respect to the plane perpendicular to the axis of the annular cleaning head, so that the nozzles are oriented to eject the liquid towards the axis of the annular cleaning head.
    [0004] According to another group of features, the cleaning device comprises guiding means in longitudinal displacement of the camera or the cleaning head. The guide means may be carried by the drive means and may consist of a rod integral with the drive means and in a sleeve disposed projecting from the camera or the cleaning head and in which said rod is capable of to slide. According to a series of advantageous features, taken alone or in combination with each other and with the characteristics described above, it is also possible for the driving means of the cleaning head or the camera to be hydraulic. In this context, the drive means comprise a chamber in which is slidable a piston, integral with the camera or the cleaning head, under the effect of the pressure of a liquid flowing between a first and a second access formed in said chamber, said piston being recalled in position by a spring housed in said chamber. The first port 15 may be connected to a liquid inlet pipe and the second port may be connected to a separate supply pipe connected at another end to the cleaning head. It is advantageous that the fluid pressing the piston, and moving the camera or the cleaning head, is cleaning liquid subsequently used for cleaning the lens.
    [0005] In a preferred embodiment of the invention, the drive means are secured to the camera, which is able to follow the movement generated by said drive means while the cleaning head remains fixed. It will be understood, however, that provision may be made for the drive means to be secured to the cleaning head, which is able to follow the movement generated by said drive means while the camera remains stationary. The invention also relates to a motor vehicle comprising a device for cleaning a camera as just described above. In a preferred embodiment of the invention, the camera capable of being cleaned by said cleaning device is a rearview camera, arranged at the rear of the vehicle and oriented to take views of a scene. road extending to the rear of the vehicle. The invention thus finds a particularly advantageous, but not exclusive, application in the field of parking assistance for motor vehicles.
    [0006] In the case where the cleaning device provides for moving the camera relative to the cleaning head, the latter is made fixed with respect to the structure of the motor vehicle, so as to be substantially flush with respect to the outer body of the vehicle . The camera is then made movable between a passive position set back from the cleaning head and an active shooting position in which the lens disposed at the end of the camera is also flush with the outer body. The invention finally relates to a method for cleaning a motor vehicle camera, in which the camera is cleaned by ejecting liquid from a cleaning head, and in which a movement instruction is first generated. from the camera or cleaning head to pass from a passive position where the cleaning head is out of the field of the camera to an active position where the cleaning head is facing the camera, and in a second time a liquid ejection instruction by the cleaning head when the latter is in said active position.
    [0007] According to an advantageous characteristic of this method, provision can be made for the displacement instruction and the ejection instruction to be carried out by the same cleaning fluid circulation instruction in a hydraulic circuit which successively controls the movement of the camera or of the cleaning head and the ejection of liquid by the cleaning head disposed at the end of the hydraulic circuit. Other features and advantages of the present invention will appear more clearly with the help of the description and the drawings, in which: FIG. 1 is a perspective view, seen three quarter front, of a cleaning device according to FIG. invention, in a passive position in which a cleaning head of the device is disposed around a camera of this device, to not interfere with the shooting by the camera; FIG. 2 is a perspective view, seen from three quarters of a quarter, of the cleaning device of FIG. 1, this time in an active position in which the cleaning head is able to eject liquid on the lens of the camera. ; - Figures 3 and 4 are perspective views, detail of the cleaning head and nozzles therein, respectively in the passive position of Figure 1 and in the active position of Figure 2; FIGS. 5 and 6 are side views of the cleaning device as previously illustrated and in which a piston for moving the cleaning head is made visible in broken lines, FIG. 5 illustrating the device in the position FIG. 1 illustrates the device in the active position of FIG.
    [0008] A cleaning device 1 according to the invention comprises in particular a camera 2 and a cleaning head 4, as well as translation drive means 6 able to generate a relative movement of the camera with respect to the cleaning head, between a passive position (visible in FIG. 1) in which the head is retracted around the camera so as not to hinder the shooting and an active position (visible in FIG. 2) in which the cleaning head is disengaged from the camera to extend facing the lens and allow the cleaning function of the latter. In the illustrated embodiment which follows, the driving means 6 are connected directly to the camera so that the relative displacement between the camera and the cleaning head is achieved by moving the camera. In this embodiment, it is advantageous to provide that the camera and the cleaning head are implanted in the vehicle structure so that the end of the camera allowing the shooting and the face of the cleaning head facing towards the outside of the vehicle are arranged substantially flush with the exterior bodywork of the vehicle when the camera is to acquire images of the road scene, here in the so-called passive position of the cleaning device. The camera 2 forms means of shooting a road scene located indifferently around the vehicle, and advantageously behind the vehicle to give information to the driver when it recedes. The camera comprises at a longitudinal end, here facing the rear of the vehicle, a lens 7 having the shape of a cylinder of circular section and which has at its free end a lens 8, which should be cleaned at a periodicity given, 10 or before each use of the rear view camera. The camera further comprises a connection plate 10 of a translation drive shaft 12 disposed at the output of the drive means 6. The drive shaft is thus secured to the camera and its movements in longitudinal translation generate corresponding longitudinal displacements of the camera. The camera also comprises, as is visible in Figures 1 and 2, at least one sleeve 14 which is arranged laterally projecting from the camera so as to have a bore which extends longitudinally to receive a 16 integral guide rod driving means. It may also be provided complementary longitudinal guide means, not shown here, carried by the vehicle structure, which support the weight of the camera during its longitudinal movements. The cleaning head 4 has an annular shape, whose axis coincides with the axis of the camera lens, and whose internal diameter is substantially greater than the external diameter of the lens 7, to be able to surround the outer diameter of the lens 7. in the passive position in which the cleaning head is retracted and arranged around the lens so as not to be in the field of view of the camera, in front of the lens.
    [0009] The cleaning head has an outer longitudinal end face 17 facing towards the outside of the vehicle as well as an internal longitudinal end face 18 facing towards the front of the vehicle in the arbitrary direction chosen in the figures. and turned towards the camera when the device is in the so-called active position 5 visible in FIG. 2. The external end face is here represented flat, but it is understood that it plays no part in the cleaning function, and that as soon as then, it may have a different shape in particular to adapt to the size of the vehicle structure around the camera and to come flush with the outer body of the vehicle, and / or to allow the greatest possible deflection of the cleaning head in the allocated space. The inner longitudinal end face 18 comprises spray nozzles 20 which are arranged all around the circumference of the head. Regular provision of the nozzles is provided, the number of nozzles and the spacing between each nozzle being left to the discretion of the manufacturer. The nozzles are arranged in a circle around the axis of the cleaning head, and it is understood that the circle formed by the nozzles has a diameter greater than the diameter of the lens since the inner face of the head that carries them is able to take a passive position around the objective carrying the lens. As a result, the nozzles and the inner face are arranged so that the nozzles are oriented to eject the liquid, when the device is in the active position, towards the inside, ie towards the axis of the annular cleaning head. According to the illustrated embodiment, said inner face comprises a plane inclined relative to the plane perpendicular to the axis of the annular cleaning head, thus forming a cone portion, and the nozzles are arranged to make an ejection of the liquid perpendicular to the inner face. The translation drive means 6 are able to control the translation of the camera away from and towards the cleaning head. A particularly advantageous embodiment will now be described in which the drive means are hydraulic and in which it is the cleaning liquid which also serves as a hydraulic system pressure liquid. Alternative embodiments will be detailed below, other possible embodiments of these drive means. In the case illustrated, the drive means comprise in particular a chamber 22 in which is slidable a piston 24 secured to a connecting rod 5 forming the drive shaft 12 as previously described. The chamber 22 consists of a hollow cylinder, formed by a circular wall 25 and delimited longitudinally by a first so-called proximal wall 26, turned towards the camera, and by a second so-called distal wall 28. The proximal wall 26 is pierced at its center to allow passage to the connecting rod 12 which connects the camera to the piston housed inside the chamber. Sealing means are provided between this opening in the proximal wall and the connecting rod so as not to leak liquid present in the chamber. The piston 24 is housed in the chamber and has a shape of disc of dimensions complementary to those of the circular wall, slightly lower to allow its sliding in the chamber without however liquid can flow between the piston and the circular wall. A spring 30, spiral spring type, visible in Figures 5 and 6, is disposed between the distal wall 28 and the face 31 of the piston facing the distal wall. The spring is constrained so that it tends to push the plunger toward the proximal wall. As seen in Figures 1 and 2 for example, two pipes are connected to the chamber 22 of the drive means. A first pipe 32, said fluid supply chamber, opens into the chamber at a first hole 33, formed in the circular wall of the chamber and 25 disposed near the proximal wall. A second pipe 34, said liquid supply of the cleaning head, connects this cleaning head to the chamber at a second orifice 36, also formed in the circular wall of the chamber, aligned longitudinally with the first orifice and disposed substantially in the center of the chamber.
    [0010] The drive means further comprise, as may have been mentioned above, a guide rod 16 which extends longitudinally projecting from the proximal wall of the chamber and which has a diameter such that this rod can come and stay in the sheath of the camera. The longitudinal dimension of the rod is such that it can not escape the sheath regardless of the active or passive position of the device. This longitudinal dimension will be calculated in particular as a function of the displacement of the piston in the chamber of the drive means. The cleaning device of the invention will firstly be described in a passive position, in particular with reference to FIGS. 1 and 5. In this passive position, the cleaning head 4 is arranged around the objective 7 of FIG. the camera, set back from the lens 8, so as not to be in the field of view of the camera. The head does not interfere with the quality of shooting and driver assistance.
    [0011] The spring 30 housed inside the chamber 22 pushes the piston 24 into a first extreme position, in which the piston is at the closest to the proximal end wall. In this first extreme position, the piston is as far back as possible according to the direction chosen arbitrarily in the figures and therefore the camera, made integral with the piston by the drive shaft 12 and the connection plate 10, is also as far back as possible, the lens of the camera and the lens at its end being pushed inside the housing defined by the annular shape of the cleaning head, flush with the body of the vehicle on which the device is implanted. The passive position is stable since the liquid injected into the chamber 22 through the first orifice 33 does not generate enough pressure to cause the piston to move against the return force of the spring 30. We are now going describe the operation of the cleaning device so that it goes into an active position based in particular on the illustrations of Figures 2 and 6.
    [0012] 3027008 WFR2115 10 When a situation is detected in which the reversing camera will potentially be used, for example when the clutch is engaged, or when the previously defined cleaning period comes to an end, a control module generates the sending liquid inside the chamber 22 via the first orifice 33 through the supply pipe 32. The liquid creates a pressure on the piston 24 by filling the chamber and it pushes on the piston in the direction of its distance of the proximal wall. The longitudinal displacement of the piston towards the front of the chamber, according to the orientation chosen in the figures, causes the simultaneous movement of the camera 2 toward the front of the vehicle, in disengagement of the cleaning head 4, which remains fixed. . The liquid pushes on the piston by compressing the spring 30, and the portion of the chamber filling with liquid, between the proximal wall 26 and the piston in displacement, continues to grow, at least until the liquid reaches the second orifice 36. The liquid can then exit through this second access. When the liquid present in the chamber is evacuated in part by the second orifice, the piston 24 finds a position of equilibrium between, on the one hand, the pressure exerted by the spring 30, and on the other hand the pressure exerted by the quantity of water that equilibrates between the liquid inlet by the first access and the liquid outlet by the second access. The piston tends to return to its original position and forces the liquid to drain through the second port, pushing it toward the cleaning head via the feed pipe. The pressure exerted on the liquid in the supply pipe 34 by this piston return effect ensures a sufficient ejection speed of the liquid at the outlet of the spray nozzles 20 for sweeping the impurities and cleaning the lens 8 correctly.
    [0013] Advantageously, according to the embodiment described, the cleaning liquid which is to be sprayed on the lens is used beforehand as hydraulic pressure control fluid to effect the relative movement of the camera and the cleaning head and to move the cleaning device from the passive position to the active position. It is therefore the same liquid which serves first of all as a pressure liquid and which serves subsequently, when its action of regulating the hydraulic pressure has made it possible to position the cleaning device in the desired active position. cleaning fluid ejection to the lens at the cleaning head, which is at the end of the hydraulic circuit in which the cleaning liquid flows and which passes successively through the chamber of the drive means and by the head of cleaning.
    [0014] When it is desired to iron the cleaning device in the passive position, in particular so that the camera can take pictures without the cleaning head being in the field, the control module generates a cut-off instruction of the arrival of liquid in the room. The spring 30 then pushes the piston 24 into its original position against the proximal wall 26, by displacing the remaining liquid present in the chamber via the first access, so that liquid remains in the supply pipe, ready for immediate use when it is again desired to move the cleaning device into the active position. The return of the piston to its original position against the proximal wall generates the simultaneous movement of the camera in the direction of the cleaning head. The foregoing description clearly explains how the invention makes it possible to achieve the objectives that it has set itself, and in particular to propose a cleaning device in which a cleaning head is able to clean a camera lens correctly, in particular while providing a passive position in which this head does not interfere with the camera shooting, the cleaning device must be able to pass, easily and with a minimum of movement, advantageously from this passive position to the active position of the camera. cleaning. Of course, various modifications may be made by those skilled in the art to the structures of the cleaning device, which have just been described as non-limiting examples, provided that relative movement of a camera is allowed. method for assisting the driving of a vehicle with respect to a cleaning head, to move from a passive position in which the head and the camera are grouped to an active position in which they are separated the one of the other to facilitate the jet of liquid from the head to the camera lens. The embodiment which has been described in detail above is not limiting of the invention. In any event, the invention can not be limited to the embodiment specifically described in this document, and extends in particular to all equivalent means and any technically operating combination of these means.
    [0015] Thus, variants not shown are provided and some are described below, without however this list is exhaustive: - it can be provided that the drive means comprise an electric motor which ensures the relative displacement in translation of the camera and the cleaning head, while an independent supply circuit provides the supply of cleaning liquid to the cleaning head when the device is in the active position; it can be provided that the drive shaft of the drive means is secured to the cleaning head and no longer to the camera and that the longitudinal translation movements of the piston and the drive shaft 15 generate corresponding longitudinal movements of the cleaning head. It will be understood that in this case, instead of seeking to move the camera longitudinally backwards, it will be sought to move the cleaning head longitudinally forwards, for the same final purpose of disengaging the head from the camera and allow ejection of cleaning liquid from the spray nozzles from the head to the camera lens; it can be provided that the conditions for triggering the cleaning of the lens of the camera are distinct, and in particular that the liquid is brought to the cleaning head simultaneously with a cleaning of the rear window of the vehicle. 25
