    DEVICE FOR CLEANING AN OPTICAL DETECTION SYSTEM FOR
    MOTOR VEHICLE
    The present invention relates to the field of optical detection systems used for driving assistance of motor vehicles, and more particularly relates to devices for cleaning the sensors of these systems.
    Optical detection systems equip a growing number of motor vehicles to assist the driver of the vehicle in certain driving situations, such as parking assistance with a camera or an infrared-type radar. In order for these driving assistance devices to be as effective as possible, it is essential that the optical sensors of these detection systems are clean, whether it be the lens of a camera or of another type. optical sensor, and for example laser sensors (commonly called LIDAR) or other sensors based on the emission and / or detection of light in the visible or invisible spectrum for humans, in particular the infrared.
    It is known to place, in the vicinity of these optical sensors, a cleaning device capable of projecting a determined amount of cleaning liquid on the associated optical sensor just before the shooting or detection is carried out. And, to avoid any risk of pollution of the sensor considered by any traces that such a cleaning liquid could leave (drops, drips, etc ...), it is also known to proceed to the projection, after that cleaning fluid, a drying fluid, especially air, which allows to clear the optical sensor of the cleaning liquid and residual dirt that it then entails with him. It is understood that these cleaning devices must not however interfere with the operation of the sensor by finding in the field of view of the sensor when it is in operation.
    For this, the elements allowing the distribution of cleaning and / or drying fluids are generally able to be moved between a working position in which they are placed substantially in front of the optical sensor to ensure cleaning, and a position of rest in which they are retracted relative to the sensor so as not to hinder its operation. Moreover, these devices must be as compact as possible to meet the constraints of space within the restricted space of the vehicle in which the driver assistance device is received.
    The aim of the present invention is to propose a solution that makes it easier to implement such an optical detection assembly and the associated device for cleaning its optical sensor, and that allows a simple control of this cleaning device between the positions. work and rest.
    For this purpose, the invention proposes a device for cleaning an optical sensor of an optical detection system for a motor vehicle, which comprises a set of routing and distribution of a cleaning fluid and a fluid of drying. According to the invention, the cleaning device comprises electric motorized means for moving in a linear movement this fluid conveying and distributing assembly between a working position, in which the fluids can be distributed on an outer surface of the optical sensor. and a rest position.
    The motorized electrical means have at their output a drive shaft made integral with the fluid conveyance and distribution assembly, said drive shaft being moved linearly and thus capable of transmitting to the routing and distribution assembly. this translational movement generated by the motorized electric means. According to various embodiments, it may be provided that the motorized electrical means consist either of a linear actuator, said drive shaft then consisting of an output rod of the directly translated actuator, or a rotary motor, said shaft of drive then consisting of a rack actuated by a pinion integral with a rotor of said motor.
    A series of features, taken alone or in combination, may be provided for the configuration of a cleaning device in which the fluid delivery and distribution assembly, which comprises at least one connection piece for feeding each fluid and distribution pipes to one or more spray nozzles of these fluids, is housed in a housing configured to cooperate with the drive shaft.
    This housing may include in particular a fixing zone of the drive shaft, a distribution portion, carrying at least one fluid spray nozzle, and a feed portion, carrying at least one connecting end and at least one distribution line.
    The fixing zone may form an extension of the housing offset from the passage of the at least one distribution pipe, and in particular shifted to the same side of the housing as the side on which is arranged the at least one fluid spray nozzle.
    According to features of the invention relating to this attachment zone, it may have a notch of shapes and dimensions corresponding to those of the section of the drive shaft. The notch may be blind, and may be of rectangular shape corresponding to a rectangular shape of the section of the drive shaft.
    According to various embodiments of the invention, this electric motor can be a linear output motor, or a rotary output motor in which the output shaft is connected to a rack, thereby transforming the rotational movement of the shaft. motor output in a linear motion.
    It will be understood that the linear movement which makes it possible to bring the routing and distribution assembly into the working position, so that the spray nozzles for the cleaning and / or drying fluids are opposite the optical sensor to be cleaned, can to be directed in different directions with respect to the vehicle, without this modifying the operation of the cleaning device according to the invention.
    The motorized electric means may comprise a stepping motor, which is controlled to generate a displacement only over the distance between the working position and the rest position, or it may comprise a continuous motor, end stops being provided to correspond to the working and rest positions of the fluid conveyance and distribution assembly. The invention also relates to an optical detection system for a motor vehicle, comprising at least one optical sensor, and a device for cleaning this sensor as just presented. Other characteristics, details and advantages of the invention will emerge more clearly from a reading of the description given below by way of indication, in relation to the appended figures, in which: FIGS. 1 and 2 are diagrammatic representations of side of an optical detection system and associated cleaning device according to one embodiment of the invention, the cleaning device being illustrated in a working position (Figure 1) and in a rest position (Figure 2). ); FIG. 3 is a side view, opposite to the angle of view of FIGS. 1 and 2, of a delivery and injection assembly of cleaning and / or drying fluid of the cleaning device; illustrated in Figure 1; and FIG. 4 is a view from above of routing and injection of cleaning and / or drying fluid of the cleaning device illustrated in FIG. 3.
    It should first be noted that if the figures set forth the invention in detail for its implementation, they can of course be used to better define the invention where appropriate.
    Furthermore, the invention will be described in the following in its application to an optical detection system comprising a camera equipped with a lens. As indicated above, the invention is however not limited to this application, and extends to any optical detection system of the vehicle implementing at least one optical sensor such as, by way of non-limiting examples. exhaustive: laser sensors, sensors based on the emission and / or detection of radiation in the visible or invisible spectrum.
    FIGS. 1 and 2 schematically illustrate an optical detection system associated with a cleaning device made according to a first embodiment of the invention, the optical detection system comprising here a camera 1 equipped with a lens 2. To this system an optical detection device is associated with a device for cleaning the lens 2, formed in particular by a delivery and distribution assembly for a cleaning fluid and a drying fluid. More particularly, this routing and distribution assembly has connection ends 3 and 4 to feed pipes not shown here, respectively for conveying a cleaning liquid from a not shown storage tank, and for the delivery of a drying fluid, and it has a set of first spray nozzles 5, for the projection of the cleaning liquid, and a set of second spray nozzles 6, for the projection of a drying fluid. Cleaning liquid and drying fluid circulate inside a casing 7 of the routing and distribution assembly, in distribution ducts 8 supplying the nozzles, the ducts being shown in dotted lines in FIG. 4 The spray nozzles 5 and 6 are arranged in the vicinity of each other on the same face of the casing, at a first longitudinal end thereof, opposite to the second longitudinal end where the connection ends 3 and 4 extend. .
    The housing 7 is made movable to move between a working position, more particularly illustrated in FIG. 1, in which the fluids projected by the projection nozzles 5 and 6 are able to reach an outer surface of the lens 2, and a rest position, illustrated in Figure 2, wherein the jet nozzles are recessed relative to the lens 2 and wherein the housing 7 can advantageously be retracted into a vehicle body member. It is understood that no fluid is projected towards the lens when the housing 7, and the associated projection nozzles 5 and 6, are in their rest position, especially when this rest position is a retracted position in the bodywork of the vehicle.
    According to the invention, the movement of the casing 7 and the movement of the routing and distribution assembly consisting of connection ends 3 and 4, projection nozzles 5 and 6 and distribution ducts 8 is a linear movement. obtained by electric motor means 9. As illustrated in Figures 1 and 2, the passage of the housing 7 and the associated routing and distribution assembly, a working position to a rest position, is made by a translation movement, in or near the motorized electric means. This limits the necessary space around the cleaning device so that it can move from its active position to its rest position.
    The motorized electric means 9 are controlled by a control device, which sends a start-up instruction of the motorized electric means when information relating to the use of the optical detection system is received, that use is a future use. , or past use. In other words, information of imminence of use of the optical detection system, of the type of stop of the vehicle and passage of the speed corresponding to the reverse gear, or information of end of use of the optical detection system, can trigger implementation of the motorized means for performing a cleaning of the optical sensor, before or after its use. Without implementation instructions, the entire routing and distribution of cleaning and drying fluids remains in a rest position, and the motorized electric means are not powered. This results in a limited energy requirement for this function since the cleaning operations are episodic and fast.
    It is understood that the use according to the present invention of electrical systems makes it possible to facilitate the detection of the blockage of the system, in particular in case of freezing. The associated control system can thus simultaneously cut off the power of the systems implemented, namely the motorized means but also the pump for example, which has the advantage of not forcing on the parts of the system.
    Different embodiments may be implemented in the context of the use according to the invention of electric motorized means generating a linear movement of the associated routing and distribution assembly.
    Variants may include the type of engine. We can indifferently implement a rotary electric motor or a linear electric motor, as long as the drive shaft 10, at the output of the electric motorized means 9, knows a linear movement that it can transmit to the housing 7. In the case of a linear electric motor, the housing is directly mounted on the output shaft, while in the case of a rotary electric motor, the housing is mounted on a rack which forms the drive shaft, the movement is made linear by a toothed connection with a rod connected to the rotor of the motor. Other variants may relate to the mode of operation of the engine and in particular its timing. More precisely, the linear movement can be advantageously obtained by an electric motor of the step-by-step type. Such a motor is dimensioned to produce a determined displacement of the drive shaft at the output of the motor, between two extreme positions, being understood that a first extreme position of the drive shaft corresponds to the rest position of the drive shaft. fluid flow and distribution assembly 3, 4, 5, 6, 7, 8, and that a second end position of the drive shaft corresponds to the working position of this assembly. As an alternative embodiment, it is possible to provide a continuous motor associated with end-of-displacement stops which sends end-of-travel information to the control module of the electric motor in order to stop the supply thereof.
    In each of these cases, the linear movement of the housing 7 is generated by the linear displacement of the drive shaft 10, along the arrow F1 illustrated in FIGS. 1 and 2.
    According to an advantageous characteristic of the invention, the housing 7 is directly fixed on the drive shaft 10 sliding at the output of the electric motor 9. For this purpose, the housing 7 comprises a fastening zone 12 carrying a notch 13 of shapes and of dimensions corresponding to those of the section of the drive shaft 10. In particular, this notch 13 can take a rectangular shape, in which is housed the drive shaft of rectangular section also, which allows to prohibit a relative rotation of the housing relative to the drive shaft around the sliding axis of this shaft.
    It will be noted more particularly that the housing has several distinct parts, among which a first distribution portion 14, carrying the projection nozzles 5 and 6, a second portion corresponding to the attachment zone 12, and a third supplying portion 15 connecting ends 3 and 4 and distribution lines 8 shown in dashed lines in FIG. 4.
    The fastening zone 12 forms an extension offset with respect to the passage of the fluid distribution pipes, and here in particular shifted on the same side of the casing 7 as the side on which the fluid spray nozzles 5 and 6, respectively, are arranged. this case. Thus, the flow of fluids in the distribution pipes 8, from the connection ends 3 and 4, is not disturbed by the presence of the notch 13 of the attachment zone 12 and by the possible presence of the drive shaft 10 in this notch. It is, of course, to be noted that such an embodiment is not exclusive: in general, the invention provides that the fixing of the housing 7 with the drive shaft at the output of the electric motor 9 which ensures the linear movement of this assembly (whether it is a linear output shaft or a rack associated with a rotary output shaft) is defined in such a way that it does not cause any disturbance of the flow of these fluids. The shaft can be fitted or fixed by screwing, in this notch 13, here represented blind. One could provide a through opening instead of a notch, and again provide adequate fastening means to transmit to the housing 7 the linear movement of the drive shaft.
    As just described, the invention makes it possible, by simple means, to provide a compact and effective device for positioning the cleaning device of an optical sensor of an optical detection system installed on a motor vehicle.
    As mentioned above, if the invention was here described and illustrated in its application to an optical assembly implementing a camera, it can not be limited to this application, and it extends any detection assembly implementing an optical sensor. Similarly, the invention can not be limited to the means and configurations described and illustrated, but it also extends to any means or equivalent configurations and any combination of such means.
