Definitions
- the present invention relates to an interference suppression device occurring in a capacitive sensor provided with a plurality of detection zones.
- the present invention will be exposed in the automotive field and more specifically in the access control of a motor vehicle type "free hand".
- the vehicle is equipped with means of identification (a computer dedicated totally or partially to this function) of the approach of authorized persons (generally carrying an electronic badge able to communicate in a secure manner with the means of identification). Regular and frequent scanning is carried out to determine whether the badge of an authorized person is in the immediate vicinity of the vehicle.
- means of identification a computer dedicated totally or partially to this function
- authorized persons generally carrying an electronic badge able to communicate in a secure manner with the means of identification.
- Regular and frequent scanning is carried out to determine whether the badge of an authorized person is in the immediate vicinity of the vehicle.
- the means of identification nevertheless expect that person actually shows the intention to enter before unlocking the opening (s) of the vehicle.
- This double check aims to allow - for example - a person authorized to pass near his vehicle without systematically unlocking access or unlocking only one opening ...
- one of means that can be used to determine the actual intention of the authorized person to enter the vehicle is to place in the opening handle a proximity sensor which will allow the means of identification to be informed (when the authorized person reaches out towards the the handle of the opening).
- a proximity sensor is for example of the capacitive type and then sends a proximity detection signal to the identification means. If the previously stated dual condition is fulfilled (detection of badge clearance and detection of a body part - usually a hand - near the door handle), then the unlocking takes place and access is allowed.
- the capacitive sensor is integrated in the handle of the opening.
- a recent development has been to replace, in the opening handles, the mechanical locking and unlocking control by an electronic device. It follows that on a doorknob - for example - two areas are offered to the user; a first zone is used to open the door by means of a capacitive sensor which detects the proximity of the hand (as described above) and a second zone, also equipped with a capacitive sensor, can detect the desire of the user to lock or unlock access to the vehicle.
- the skilled person has proposed to make the handle waterproof by various methods.
- One of the methods used consists in coating the capacitive sensors in a plastic resin (polyurethane or epoxy resins for example). This process is unfortunately long and expensive. In addition, it is difficult to easily mold complex shape sensors.
- a proposed alternative is to facilitate the flow of the present water to avoid its presence. This technical solution is not satisfactory because it would require the presence of flow orifices that are incompatible with the aesthetic requirements and facilitates the coupling between the capacitive sensors in the event of a very humid atmosphere (rain, fog, etc.) due to flow orifices which do not seal said handle.
- the present invention aims to remedy the above problems, and this at cost content.
- the invention aims, in the first place, a device for suppressing the phenomenon of interference between several detection zones of a capacitive sensor subjected to a humid ambient medium, the device being remarkable in that it comprises means preventing the communication of moisture between the detection zones so as to avoid capacitive coupling between the different zones.
- the humidity can be accepted without creating any problem. This also makes it possible to dispense with the sealing overmolding steps of the prior art.
- the means preventing the communication of moisture are made in the mass of the capacitive sensor. It is then possible to assemble the sensor directly into the handle that will accommodate it.
- the means preventing the communication of moisture are constituted by at least one flexible lip. Said flexible lip (or said flexible lips) will allow easy sealing.
- the means preventing the communication of moisture are added to the capacitive sensor during its assembly.
- This embodiment has the advantage of being able to design a standard capacitive sensor and to adapt only the insert.
- the means preventing the communication of moisture are constituted by an attached seal.
- the invention also relates to a door handle of a motor vehicle equipped with a capacitive sensor having a plurality of detection zones, incorporating an interference suppression device described above.
- FIG. 1 is a three-dimensional view of an embodiment of the prior art, the handle not being completely assembled
- FIG. 2 is a three-dimensional view of an assembled handle, ready to be mounted on the sash;
- FIG. 3a is a three-dimensional view of a sensor according to the invention, viewed from above with reference to the position of FIG. 1
- FIG. 3b is a three-dimensional view of a sensor according to the invention, seen from below with reference to the position of FIG. 1,
- Figure 4 is a three-dimensional view of a door handle of a motor vehicle incorporating the invention, partially assembled.
- FIG. 1 shows the problem of the invention.
- An opening handle 10 of a motor vehicle (not shown) is made to accommodate different elements and must be assembled.
- said handle 10 consists of at least two elements: an upper part 20,
- the capacitive sensor 30 is in the form of a monoblock piece integrating the sensitive elements strictly speaking, as well as the electronics for conditioning the detected signal.
- the handle 10 shown here is equipped with two detection zones A and B for two separate commands.
- the first detection zone A may be electronically assigned to the sash lock control and the second detection zone B to the proximity detection of the authorized person wishing to enter the vehicle.
- the invention proposes to circumvent the problem of the presence of moisture without seeking to dispense with it absolutely.
- the capacitive sensor 30 is provided with a seal 50 providing the means preventing the communication of moisture between the A and B areas mentioned above.
- This seal 50 can come from manufacture (molding for example) with the capacitive sensor 30 or be a part attached to the sensor 30.
- a lip seal for example satisfies the sealing requirement.
- the invention thus lies in the fact not to fight any trace of moisture or any risk of moisture in the handle in the vicinity of the detecting zones, but to prevent the moisture present in one area from communicating with another detection area.
- the seal 50 seals between the two detection zones A and B and prohibits any moisture present in the vicinity of the one of the areas to come in direct contact with the moisture present in the vicinity of the other area. This eliminates the risk of coupling and associated interference.
- the present invention can not be limited to the single embodiment described, but covers any adaptation to the scope of the skilled person.
- the handle 10 may have more than two detection zones, each zone then being individually separated from the others.
- the embodiment provides a handle consisting of at least two elements (an upper portion 40 and a lower portion 20). It is nevertheless entirely possible to make a handle in a single hollow element into which the sensor 30 is then inserted.
- the present invention is quite suitable for capacitive sensors to operate in an aquatic environment, which is not the case of land motor vehicles described above.
