    System and method for wiping a vehicle window
    The present invention relates to a system and a method of wiping a vehicle window, in particular automobile.
    A car is conventionally equipped with windshield wipers to wash the windshield and to prevent the driver's vision from being disturbed.
    A windshield is generally equipped with two wipers, one for wiping a first area of the window, and a second for wiping a second area of the window different from the first aforementioned area.
    These wipers generally comprise a drive arm, performing an angular reciprocating movement, and elongate brushes, themselves carrying scraper blades made of an elastic material. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision. The brooms are made in the form, or, in a conventional version, articulated stirrups that hold the scraper blade in several discrete places by giving it a bend allowing it to marry the eventual curvature of the windshield, or, in a newer version called "fiat blade" (for "flat blade"), a semi-rigid assembly that keeps the scraper blade along its length thanks to one or bending vertebrae to apply the broom on the bumper -brise without having to use stirrups.
    It is known to equip the windshield of a vehicle with a sensor, for example rain. This sensor is located inside the passenger compartment of the vehicle and can be applied against an inner surface of the window. The sensor is intended to detect information through the windshield, such as the presence of water.
    The document FR-A1-2 991 948 describes a system for wiping and washing a window of a vehicle, this window being equipped with an element or sensor for analyzing the state of the windshield. The effectiveness of the sensor is particularly related to the cleanliness of the windshield, and in particular the portion of the windshield that covers the sensor. The wipers are generally used to clean this portion, which is therefore part of one of the areas swept by the brooms. In the case where the portion would be dirty and should be cleaned, the wipers are operated and run through all of the aforementioned areas, even if these areas are less dirty than the portion and do not necessarily need to be cleaned.
    This situation has a disadvantage. At least one of the wipers thus actuated is not useful for cleaning the portion and may impede the driver, and in particular cross the field of view of the driver in the case of the broom driver side, and thus disrupt it. This is especially true when the cleaning of the portion by the wipers is done automatically, without specific driver control. The invention proposes a simple, effective and economical solution to this problem. The invention proposes for this purpose a wiper system of a vehicle window, said window being equipped with a sensor, the system comprising: a first wiper blade adapted to wipe a first zone of the window, a portion of which extending at said sensor, a second wiper blade adapted to wipe a second zone of the window different from said first zone, means for actuating said first and second wiper blades for their movement on the window , and electronic means for controlling said actuating means, characterized in that said actuating means comprise a first actuating motor of said first wiper and a second actuating motor of said second wiper, and in that said means for control are configured to activate only said first motor when cleaning of said portion is desired.
    The sensor is for example a rain sensor, a sun sensor, a fog sensor, a soil sensor, a sensor panels, a camera, a video camera, a laser-based optical sensor, etc. The invention thus proposes to operate only one of the wiper blades when the portion covering the sensor must be cleaned, and not the rest of the glass. The other broom remains stationary and is therefore not likely to interfere with the driver of the vehicle.
    The system according to the invention can comprise one or more of the following characteristics, taken separately or in combination with each other: said control means are configured to activate said first and second engines when a cleaning of said first and second zones is desired, - said first blade is a blade configured to be located on the side of a driver of the vehicle, - said first blade is a blade configured to be located on the side of a passenger of the vehicle, - said portion is located substantially in the middle of the window, - said portion is located on one side of the window, - the system comprises means for spraying cleaning liquid, said control means being configured to activate a projection of liquid when cleaning said portion is desired said projection means are carried by said first blade, and said projection means and / or said means are configured to project liquid from only one side of said first blade and / or during a descent phase of said first blade on the window.
    The present invention also relates to a method of wiping a window of a vehicle, by means of a system according to one of the preceding claims, comprising a step of: b) activating only said first motor when a cleaning said portion is desired, said second motor remaining inactive.
    The method may comprise a preliminary step of: a) transmitting a signal to said control means for the purpose of activating only said first motor.
    Preferably, the emission of said signal results from a command carried out by a driver of the vehicle, or by a detection of soiling of said portion by said sensor.
    The method may comprise, during step b), a substep of activating a projection of liquid on the glass.
    Liquid spraying can take place from only one side of said first broom. The liquid projection can take place during a descent phase of said first blade on the window. The invention will be better understood and other details, characteristics and advantages of the invention will appear on reading the following description given by way of non-limiting example with reference to the accompanying drawings, in which: FIG. schematic view of a vehicle window equipped with a wiper system and a sensor, - Figure 2 is another schematic view of a vehicle window equipped with a wiper system and a sensor FIG. 3 is another schematic view of a vehicle window equipped with a wiper system and a sensor, the wiper system being in operation; FIG. 4 is a diagrammatic view of perspective of a wiper system of the prior art with a single means for actuating the wiper blades, - Figure 5 is a schematic perspective view of a wiper system according to the invention to a means of 'actionneme Figure 6 is a schematic perspective view of a wiper, and Figures 7 and 8 are views corresponding to that of Figure 3 and illustrating a wiper system. the invention during operation.
    Figure 1 illustrates a window 1 of a vehicle, for example a motor vehicle. Such a window is here a windshield 1 delimited by an inner face, facing the passenger compartment of the vehicle, as well as an outer face facing the outside of the vehicle.
    A wiper system 2 is installed on the windshield 1, in particular to evacuate the water present on the outer face, and possibly to ensure a projection of a washing liquid on the same side.
    In Figure 1, the system 2 is illustrated in a rest position, that is to say a position where the operation of the system 2 is not required. This system 2 comprises a first wiper blade 3 intended to wipe a first zone 4 of the windshield 1, the latter being illustrated by a dotted line which delimits the first zone 4. This first zone 4 is here on the driver's side of the vehicle , the first wiper blade 3 being configured to be mounted on the driver's side of the vehicle, driving left.
    The first wiper blade 3 is connected to a first point of rotation by means of a first actuating arm (not shown), the first wiper blade and the first arm performing a movement of-and- comes sweeping the first zone 4. The rotational movement of the first arm is operated by unrepresented actuating means.
    The system 2 further comprises a second wiper blade 5 intended to wipe an area 6 of the windshield 1 at least partly different from the first zone 4 of the windshield 1. In the remainder of the description, this zone swept by the second wiper blade 5 will be called the second zone 6 of the windshield 1, the latter being illustrated by a solid line which surrounds the second zone 6. It will be noted that the first zone 4 and the second zone 6 of the windshield 1 overlap at least on a central portion of the windshield, delimited by both a solid line and a dashed line and referenced 7 in Figure 1. The invention is particularly concerned with the cleaning of the second zone 6 of the windshield -brise which does not overlap with the first zone 4 of the windshield 1. More particularly, the invention contemplates the cleaning of an upper portion of the second zone 6, this portion being surrounded by a circle referenced 8 on the figure 1. This po 8 of the second zone 6 of the windshield 1 receives a sensor 9 which analyzes the state of the windshield 1 or the state of the road situated in front of the vehicle. It can thus be a rain sensor secured to the inner face of the windshield 1 and installed in line with the upper part 8. It can also be a sun sensor, a device photographic or laser optical sensor or a camera, especially for night vision. It can finally be a fog detector, dirt or a detector signs.
    The second zone 6 is on the passenger side of the vehicle, the second wiper blade 5 being configured to be mounted on the passenger side of the vehicle, while driving on the left. The second wiper blade 5 is connected to a second point of rotation via a second arm (not shown), the second wiper blade 5 and the second arm reciprocating in sweeping the second zone 6 of the windshield 1. The rotational movement of the second arm is operated by the same operating means mentioned in the current art.
    2 illustrates a window 1 'of another motor vehicle, on which is installed a wiper system 2' of which only the first blade 3 'is shown. The window 1 'is equipped with a sensor 9' which is covered by a portion 8 '.
    Figures 1 and 2 show the prior art to the present invention and show two different positions of a window sensor, namely in the middle of the window (Figure 1) and the driver side of the vehicle (Figure 2).
    In these two cases and, as shown in Figure 3, the operation of the wiper systems to clean the portion 8, 8 'is likely to hinder the driver's vision, even if this portion is not located on the driver's side 10 of the vehicle.
    FIG. 4 shows a wiper system of the prior art and in particular the common actuating means of their wiping brushes 3, 3 ', 5. These actuating means comprise a single motor 11, the shaft of which output is connected by a linkage or linkage 12 to the drive arms of the two wipers.
    Figure 5 shows a wiper system according to the invention wherein the actuating means of the wiper blades 13, 15 comprise two independent motors 14. A first motor 14 is configured to drive the first brush 13, driver side in the above example, and a second motor is configured to actuate the second brush 15, passenger side.
    Each broom 13, 15 may be of the squeegee and rudder type. It may also be a flat broom, called "fiat blade", as shown in Figure 6 or mixed (also called hybrid).
    Each wiper blade 13, 15 comprises a support 17 inside which is housed a stiffening vertebra. The support 17 further comprises a longitudinal cavity in which is threaded a squeegee, otherwise called scanning blade 18. The latter is a flexible component of the wiper blade bears against the outer face of the windshield.
    On its upper part, the support 17 is covered by a deflector 19 arranged to use the dynamic effect of the movement of the vehicle to increase the support force of the wiper blade 13, 15 on the windshield.
    Alternatively, the wiper blade 13, 15 may comprise two stiffening vertebrae. In this case, the two vertebrae are made integral with the sweeping blade 18 constituting the wiper blade 13, 15, and the latter is devoid of support 17. The sweeping blade 18 may be provided with two slots open along the wiper blade 13, 15 and arranged laterally thereon, these two slots each receiving a stiffening vertebra.
    Substantially in the center of the wiper blade 13, 15, there is a means 20 for securing the wiper blade to the arm which generates its movement, in particular its rotation. This securing means 20 comprises at least one adapter 21 connected by a pivot connection to a connector 22. The latter provides a mechanical grip on the support 17 of the wiper blade 13, 15, while the adapter 21 has the function of to ensure a mechanical connection between an end of the arm and the connector 22. Such an adapter 21 is therefore a part whose shape can be modified according to the shape of the end of the arm, for example a rectilinear end, shaped hook or having a tilting finger and one or more fastening tabs.
    At each of its ends, the wiper blade is provided with a tip 25, 26 provided with at least one housing allowing it to be slipped at least on the support 17.
    The system 2 according to the invention also comprises a windshield washing liquid supply device 1. This supply device comprises at least one washing liquid transport tube installed between at least one circulation pump. liquid and each wiper blade 13, 15.
    The supply device 10 may include this circulation pump and possibly a liquid circulation management module comprising in particular at least one valve and / or a valve, this management module then being installed between the circulation pump and the brushes. wiper, and connected to these components by washing liquid transport tubes.
    The wiper blades 13, 15 are provided with means for spraying the washing liquid so as to project the washing liquid at least on the zones 4, 6 of the windshield 1.
    As can be understood from Figures 7 and 8, the projection means may be in the form of ramps extending over substantially the entire length of the brushes. Each broom 13, 15 preferably comprises a ramp on a first side for the projection of liquid on a first side of the blade, for example upwards when the blade moves in an ascending phase, and a ramp on the other side for the projection of liquid on this side of the blade, for example downward when the blade moves in a downward phase.
    The motors 14 are of the electronically-controlled type and are each associated with electronic control means such as a printed circuit board capable of managing the motor control as well as the activation or deactivation of the washing liquid supply device. for example by electrically feeding the circulation pump washing liquid.
    In a conventional manner, the control means 30 for the motors 14 are configured to activate the motors when cleaning the zones 4, 6 is desired. According to the invention, they are further configured to activate only one of the brushes, and in particular the brush whose zone comprises the aforementioned portion 8 or 8 'covering the sensor 9. This is to clean this portion. In the latter case, the other broom remains motionless, its engine being inactive.
    Figures 7 and 8 show embodiments in which the windshield 1 is similar to that of Figure 1 and is equipped with a sensor substantially in its middle and in the high position. The control means are then configured to activate the drive motor 14 of the second blade 15 in order to move only this blade and clean the zone 6 and therefore the portion 8, 8 '.
    FIG. 7 shows an embodiment in which cleaning liquid is sprayed from one and the same side of each broom when the second broom 15 is actuated. Although the first broom 13 remains immobile, liquid is sprayed from one of its ramps. Liquid spraying is done here during the upward movement of the second blade and during an ascending phase so that the liquid spray is spread and removed from its deposit on the windshield.
    Figure 8 shows an alternative embodiment in which cleaning liquid is sprayed from one side of the first broom while moving. The first broom 13 remains stationary and is not used to project liquid on the windshield. The liquid spraying is done here during the downward movement of the second blade 15 and during a downward phase so that the liquid spray is spread and removed from its deposit on the windshield.
    It is understood from Figures 7 and 8 that the visual comfort of the driver is respected because the inactive brush 13 does not cross the field of view of the driver and does not disturb the cleaning of the portion 8, 8 '.
