    [0001] TECHNICAL FIELD The invention relates to the field of driving assistance and especially 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. Cleaning devices are known which comprise a mobile cleaning head between a retracted position in which it is not in the field of the camera and therefore does not interfere with the shooting and an active cleaning position in which the head is deployed to face the camera and to spray cleaning liquid onto the camera lens. For example, reference may be made to document DE10232227 to illustrate this type of device, in which the camera is fixed, housed in a vehicle structure element so that the lens of the camera is flush with the outer face of the corresponding wall of the vehicle. structural element. The cleaning head in an active cleaning position is disposed protruding from the structural element and the projection of the cleaning liquid can splash passers in the vicinity of the vehicle. In addition, the cleaning head is small and fragile, and is connected to a deployable structure and hydraulic power cables. The mobility of this set weakens the cleaning head and may break the power cables in the long term. The present invention is in this context and its purpose is to provide a camera cleaning device which is particularly effective and which avoids the disadvantage presented above. For this purpose, the invention relates to a device for cleaning a camera lens of an automobile vehicle via a cleaning head, in which the camera and the cleaning head are arranged. so as to be facing in a cleaning position in the lens and to be distant from each other in an active shooting position.
    [0002] According to the invention, the device comprises a fixed cleaning head, protected from a structural element of the vehicle, and a camera made mobile by means of drive means. The head is housed sheltered from a structural element of the vehicle and the drive means are able to generate a relative movement of the camera with respect to the cleaning head between a passive position of shooting in which the camera is arranged sheltered from said vehicle structure element facing the cleaning head, to allow ejection of cleaning liquid towards the lens, and an active position in which the camera is deployed at a distance of the structural element of the vehicle to allow shooting.
    [0003] It can be seen that the device according to the invention has a fixed cleaning head and a moving camera between a shooting position and a cleaning position. It is particularly interesting according to the invention that it is the camera that moves, and that the cleaning head, smaller and therefore more fragile, is fixed. Moreover, the fact that the head is fixed inside the structure 20 makes it possible to protect this fragile cleaning head, and this also makes it possible to propose a cleaning position which is not in the open air, so that the projection of cleaning liquid takes place inside the structure of the vehicle and does not create splash of passers-by, nor dirt or residues of washing liquid on the external body of the vehicle.
    [0004] According to various features of the invention, taken alone or in combination: the cleaning head comprises means for connection to a cleaning liquid supply pipe and spray means by which the liquid is able to exit from said head toward the lens in said operative position of the camera; - the cleaning head has a face provided with nozzles forming the spray means, said head being arranged so that the nozzles are oriented towards an area in which the camera is adapted to take said passive shooting position. And the lens is turned towards the cleaning nozzles in this passive shooting position; - The camera is locked in rotation when moving between the active shooting position and the passive shooting position, for the correct orientation of the lens, both to receive the cleaning liquid sprayed by the spray nozzles, only to make a correct shot of the road scene. According to a series of advantageous features, taken alone or in combination with each other and with the features described above, it is also possible to provide: the driving means comprise a housing for supporting the camera, a rod made integral with the housing, and an actuator adapted to move the rod in translation; - The housing has a housing for the camera arranged so that the lens opens from one side of the housing, a separate face of the housing serving as a connecting face with the rod; The housing comprises a cover extending substantially perpendicularly, in at least one direction, the face of the housing opposite to the connecting face with the rod; - The housing comprises guide means in longitudinal displacement relative to the actuator, complementary to the rod.
    [0005] According to another series of features, it can be provided that the actuator of the drive means of the camera is hydraulic. It can be provided in this case that the actuator comprises a casing forming a chamber in which is slidable a piston, integral displacement of the camera via the rod which is connected at one end to the piston and comes out 30 of the housing by a hole made in a so-called proximal wall of the housing to be connected to the housing at the other end, the piston sliding under the effect of the pressure of a liquid injected between an orifice formed in the so-called distal wall 3031919 WFR2166 4 casing of the actuator, said piston being biased into position by a spring housed in said chamber between the piston and the proximal wall. The fluid pressing the piston, and moving the camera, may be cleaning liquid suitable for use in cleaning the lens.
    [0006] It can also be provided that the device comprises control means capable of developing instructions for controlling the cleaning head as a function of input data relative to the position of the camera on the one hand and to the position of the camera on the other hand. cyclic cleaning conditions. The invention also relates to a motor vehicle comprising a device for cleaning a camera as just described above. The cleaning device provides for moving the camera relative to the cleaning head, and the latter is made fixed with respect to the structure of the motor vehicle within this structure. The camera is made movable between a passive position facing the cleaning head, within the vehicle structure, and an active shooting position, clear of the vehicle structure. By passive and active position is here passive and active position of shooting, it being understood that these positions respectively correspond to an active and passive position cleaning the camera.
    [0007] In a preferred embodiment of the invention, the camera capable of being cleaned by said cleaning device is a rearview camera, disposed at the rear of the vehicle and oriented to take views of a road scene. 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. The structural element inside which the cleaning head is housed is then a rear bumper shield. The invention relates more particularly to a motor vehicle, in which the cleaning head is made fixed inside the rear bumper shield and in which the camera is able to take an active position of taking the view from the outside. bumper shield and a passive position for shooting the inside of the bumper shield, an opening being provided in said shield to allow the passage of the camera from one position to another. According to particular characteristics of such a vehicle, the rear bumper shield has a substantially horizontal upper wall and a substantially vertical front wall, and the opening for the passage of the camera is made in the upper wall. The camera can be surmounted by a hood with dimensions substantially equal to those of the opening, so as to cover said opening when the camera is in the passive shooting position. And in this case, it can be provided that the edges defining the opening 10 comprise a bearing surface for the cover recessed from the outer face of the upper wall which extends. 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. the camera to move from an active position where the camera is clear of the vehicle structure to take shots at a passive position where the cleaning head is facing the camera inside the structure, and in a second step a liquid ejection instruction by the cleaning head when simultaneously the camera is in said passive position, and cyclic cleaning trigger conditions are met. Other features and advantages of the present invention will become more apparent from the description and from the figures in which: FIG. 1 is a perspective view, seen from a quarter rear view, of a cleaning device according to FIG. invention in a preferred application in a rear bumper shield, said device being in an active shooting position in which a camera of the device is deployed out of the shield, to allow shooting; FIG. 2 is a detailed view of the device of FIG. 1, making the camera deployed outside the rear bumper of the vehicle particularly visible; - Figure 3 is a detail view, similar to that of Figure 2, the device 5 in a passive position of shooting with the camera retracted in the vehicle structure; FIG. 4 is a view of the interior of the vehicle structure, with the device in the passive shooting position, and in which the cleaning head and the associated liquid supply circuit 10 are made visible, as well as the drive means of the camera; and FIGS. 5 and 6 are sectional views of the drive means of the camera in a first extreme position and a second extreme position, respectively.
    [0008] A cleaning device 1 according to the invention is illustrated in the figures in its preferred application, namely in a rear view camera system disposed at the rear of the vehicle, in the vicinity of a rear bumper 2 arranged transversely, in particular in a trunk door 4, as can be seen in FIG. 1. The device notably comprises a camera 6 and a cleaning head 8, 20 as well as translation drive means 10 able to generate a relative movement of the camera relative to the cleaning head, between an active shooting position (visible in FIG. 2), where the camera is disengaged from the vehicle structure in order to take pictures of the road scene situated behind the vehicle, and a passive position (visible in FIGS. 3 and 4) in which the camera is retracted into the vehicle structure, facing the cleaning head which remains stationary in the same vehicle structure cule. The camera 6 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. In this case, the structural element is a rear bumper shield 2 which comprises a substantially horizontal upper wall 12 disposed directly under the rear trunk door, and a substantially vertical front wall 14 which extends the top wall down. An internal clearance is provided behind the walls of the shield to form a housing of said camera and cleaning head, and said drive means. The shield has in this context an opening 16 of communication between the housing and the outside of the shield, so that the camera can pass through this opening to take an active shooting position and then resume its passive position, retracted into the shield. This opening 16 is made, in the case illustrated in the figures and as is particularly visible in Figure 2, in the upper wall 12 of the shield, by cutting thereof. The opening has a substantially rectangular shape, the dimensions of which are substantially greater than the dimensions of a housing 18 within which the camera is housed, so as to allow the passage of this camera through the opening. The housing 18 is part of the drive means 10 of the camera. It is mounted at the end of a rod 20, set in motion by means of an actuator 22 which forms with the rod and the housing said drive means. The casing has a cube shape connected on a first face 24 to the rod, and 20 of which a second face, opposite the first face and therefore to the rod, is carrying a cover 28 extending substantially perpendicularly, at least in two directions, the second face. Furthermore, the housing houses a camera lens 30 which has a lens 32 opening on a third face 34 of the housing perpendicular to the first and second faces, and which should be cleaned at a given periodicity, or after each use of the reversing camera. The housing also comprises a guide lug 36, which originates in extra thickness of a fourth face 38 of the housing and which extends parallel to the rod 20 at a distance from the latter. In the illustrated case, the guide tab has a rectangular section, it being understood that it could be of a different shape.
    [0009] In FIG. 3, the camera is shown in the passive shooting position, retracted inside the shield, seen from the outside of the vehicle. In this position, it is observed that the cover 28 closes the opening 16 made in the shield 2. It is indeed interesting that this hood makes a tight closure 5 of the shield so as to prevent rain water can particularly penetrate the shield. For this purpose, the hood having dimensions substantially equal to those of the opening, there is provided seals (not visible in the figures) on the inner face 40 of the hood facing the shield, and it is expected to forming in the upper wall of the shield at the edges delimiting this opening, all around the periphery thereof, an extension of the edges towards the inside of the opening and recessed from the outer face of the upper wall to form a support surface for the hood, so that the outer face 42 of the hood is flush with the outer face 44 of the upper wall of the shield in the passive shooting position.
    [0010] The driving means 10 comprise the housing 18 in which the camera is housed, so that the relative displacement between the camera and the cleaning head is achieved by moving the camera. As previously described, the drive means comprise, besides the housing, the rod 20 connected to the housing and the actuator 22.
    [0011] The rod extends along a translation axis substantially perpendicular to the plane in which the opening extends in the upper wall of the shield, so that the movement of the camera through the opening is not impeded. The rod is fixed at a first end to the housing housing the camera so as to be integral in movement of the camera, and it is fixed at its second end to the actuator, which drives in displacements in substantially vertical translation. This generates corresponding vertical displacements of the housing and the camera. The actuator of the drive means in translation is able to control the translation of the camera away from and towards the retracted position in which the lens is opposite the cleaning head. A particularly advantageous embodiment will be described below, in which the drive means are hydraulic.
    [0012] In the case illustrated, the actuator 22 comprises a housing 46 forming a chamber in which is slidable a piston 48 secured to the second end of the rod, under the effect of pressure differences created by the presence of hydraulic fluid. It will be understood that the piston is able to slide under the effect of this pressure between a first and a second end position, one corresponding to the passive position of shooting, retracted, from the camera and the other corresponding to the active shooting position of the camera. The chamber is delimited by a hollow cylinder, formed by a circular wall and delimited longitudinally by a first so-called proximal wall 50, facing towards the camera, and by a second so-called distal wall 52. The proximal wall is pierced at its center to let passage to the rod which connects the housing housing the camera to the piston of the actuator housed inside the chamber. Sealing means are provided between this opening in the proximal wall and the rod so as not to leak liquid present in the chamber. The piston 48 is housed in the chamber and has a shape of disc of dimensions complementary to those of the circular wall, slightly lower to allow it to slide in the chamber without the liquid being able to circulate between the piston and the circular wall. A coil spring type spring 54 is disposed between the proximal wall 50 and the piston face facing this proximal wall, wrapped around the stem. The spring is constrained so that it tends to push the piston toward the distal wall 52 when no fluid otherwise exerts pressure on the piston. A fluid supply pipe 56 of the chamber is connected to the chamber of the actuator at an orifice 58 formed in the distal wall 25 so that the fluid which is injected into this pipe opens in the chamber between the distal wall and the piston by pushing the piston towards the proximal wall. It is understood that in the illustrated embodiment, the discharge of fluid takes place by the same orifice as that through which the supply takes place. As can be seen in FIG. 4, the outer surface of the housing of the actuator carries a guide 60 inside which the guide lug 36 secured to the housing 18 can slide. The guiding of the housing and the housing camera, by the 3031919 WFR2166 10 times the rod and the guide lug, ensures an exclusively sliding movement of the housing relative to the actuator, preventing the rotation of the housing on itself during its displacement, so that the lens remains correctly oriented with respect to the road scene for shooting and with respect to the cleaning head. Also in FIG. 4, the cleaning head 8 which has at least one cleaning fluid spraying nozzle 62, facing the camera when it is in the retracted position, has been made visible. As previously stated, the cleaning head has a fixed position relative to the vehicle structure, housed inside the rear bumper shield when the application of the device is the cleaning of a camera back. The cleaning head is mounted at the end of a support arm 64 connected at its other end to the casing of the actuator 22, and the support arm extends on the one hand at a distance transverse to the axis of moving the camera not to interfere with it, and secondly vertically to have the head facing the lens of the camera when the camera is in the retracted position. In a variant not shown, the support arm is connected to another fixed point that the housing of the actuator, and for example directly on the shield structure. It is understood that it is important for the cleaning head to maintain a fixed position during the movements of the camera, irrespective of where it is fixed. However, it should be noted that in the illustrated example, the rib chain corresponding to the relative positioning of the liquid spray nozzles with respect to the lens to be cleaned is reduced, because of the fixing of the head directly on the housing of the actuator.
    [0013] In addition, a hydraulic supply pipe 66 is connected to the cleaning head for the supply of cleaning liquid. This supply pipe connects the cleaning head to a tank of cleaning fluid provided elsewhere. The cleaning head has an internal conduit, not visible in the figures, for conducting the liquid exiting the supply pipe to the spray nozzles. It could be advantageous to provide the same reservoir of liquid for carrying out the hydraulic supply function of the actuator chamber and for the supply of liquid for the cleaning of the lens via the passage through the head. of cleaning. A control module determines when and how much liquid should flow to the head. In particular, the control module will be able to establish a start-up instruction of the cleaning head when, on the one hand, the camera 5 is in the retracted position in the rear bumper shield, and on the other hand the cyclical conditions. cleaning are respected. To limit the size of the device, the supply pipe is here locked in a hook 68 integral with the housing of the actuator 22, and is shaped to follow the curvature of the support arm.
    [0014] The cleaning device of the invention will first be described in a passive position, in particular with reference to FIGS. 4 and 5. In this passive position, the camera and the cleaning head are housed within the structure of the vehicle. The camera has been brought opposite the cleaning head, which has remained fixed inside the shield, and it is therefore possible, under the effect of an appropriate control instruction, to perform the cleaning of the camera. In the absence of hydraulic fluid in the chamber of the actuator, the spring housed inside the chamber pushes the piston into a first extreme position, in which the piston is closer to the distal end wall. In this first extreme position, the piston is as far as possible from the upper wall of the bumper shield through which the camera is able to pass, and thus the camera, made integral with the displacement of the piston via the rod and housing, is also set back from this upper wall, in a position such that the lens is facing the spray nozzles of the cleaning head.
    [0015] The passive shooting position of the camera, retracted into the structural element of the vehicle, is stable when the fluid injected into the chamber, via the orifice made in the distal wall, does not generate enough pressure to cause the displacement of the piston against the return force of the spring. And it can be seen that this passive shooting position does not automatically generate cleaning of the lens, for several reasons including the possibility that a cleaning has been performed previously without the camera being made active. in the meantime, or the possibility that cleaning has been achieved there are several cycles of movement of the camera while remaining below the determined threshold of numbers of cycles from which it is necessary to carry out the cleaning. The operation of the cleaning device will now be described in order for it to move into an active position, based in particular on the illustrations of FIG. 6. When a situation is detected in which the reversing camera will potentially be used, for example when the clutch is engaged, a control module generates the sending of fluid inside the chamber via the supply pipe. The fluid creates a pressure on the plunger by filling the chamber and pushes on the plunger in the direction away from the distal wall. The longitudinal movement of the piston causes the simultaneous movement of the camera towards the outside of the vehicle structure, disengaging the cleaning head which remains fixed.
    [0016] The liquid pushes on the piston by compressing the spring, and the part of the chamber filling with liquid, between the proximal wall and the piston in displacement, continues to grow, until a determined position which corresponds to the active position of shooting of the camera. It is known to determine the second extreme position, that is to say at what distance from the proximal wall must the piston be located so that, depending on the length of the rod and the dimensions of the housing, the camera is in the adequate position for shooting without being too close and potentially hindered by the rear bumper shield and without being too much outgoing and cantilevered. It is then known to determine the amount of fluid to be injected into the chamber to reach this determined position of the piston 25 as a function of the stiffness of the spring. The piston tends to resume its initial position and when the shooting is performed, the control module generates a cut-off instruction of the arrival of fluid in the chamber so that the piston is pushed against the distal wall by ejecting the fluid out of the chamber through the orifice, in the opposite direction of the feed direction. The return of the piston to the distal wall generates the simultaneous movement of the camera towards the inside of the structural element, and when the piston is in the first extreme position, substantially against the distal wall, the lens of the camera is next to the cleaning head. The control module can then generate a cleaning liquid supply instruction to the cleaning head. When the camera is in the passive shooting position, i.e. when it is retracted into the structure and facing the cleaning head, the cleaning operation may not be systematic to save especially cleaning liquid. The cleaning may advantageously be controlled under the dual condition of a presence of the camera in the passive position of shooting and a periodicity of cleaning 10 previously defined arriving at term. The foregoing description clearly explains how the invention makes it possible to achieve the objectives it has set itself and in particular to propose a cleaning device in which the relative mobility between a camera and an associated cleaning head is achieved by the mobility. of the camera and a fixed position of the cleaning head, and in which the area in which the cleaning of the camera takes place is arranged sheltered from a structural element to avoid splashing on the outside of the vehicle . Of course, various modifications can 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 shooting position in which the cleaning head and the camera are grouped together to allow an operation of cleaning at an active position in which they are spaced from each other with the cleaning head remaining shielded from the vehicle structure and the camera deployed out of the vehicle structure for a reduced time corresponding to the duration of the shooting. 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 to any technically operating combination of these means.
    [0017] Thus, variants not shown are provided and some are described below, but this list is not exhaustive: - it can be provided that the drive means comprise a hydraulic or electrical actuator which ensures the displacement in translation of the camera; it can be provided that the conditions for triggering the cleaning of the lens of the camera are distinct from those described above, and in particular that the liquid is fed to the cleaning head simultaneously with a cleaning of the rear window of the vehicle. 10
