Definitions

  • the present invention relates to a door handle, particularly for a motor vehicle.
  • the invention relates more particularly to a door handle incorporating at least one presence sensor for detecting the presence of a user at the handle.
  • the invention also relates to a hands-free access system for a motor vehicle comprising such a handle.
  • the opening handle which was used in time only to transmit a mechanical movement via a linkage to a lock for the opening of the opening has undergone a profound change.
  • the handle has become a privileged interface between the user, carrying an identifier (for example under the form of a badge), and the system embedded on the vehicle.
  • an identifier for example under the form of a badge
  • FIG. 1 a handle as used in a hands-free system is shown in FIG. 1
  • such a handle 1 consists of two parts, a gripping portion 2 movable relative to the opening 4 of the vehicle and a part - 3 fixed essentially decorative or incorporating, for example, a backup lock. Both the movable part 2 and the fixed part 3 are made of plastic material.
  • the movable portion has an inner recess 6 serving as a housing for a support module 7.
  • the inner recess 6 also called housing
  • the housing 6 is closed by a closure element 6a.
  • the support module 7 comprises presence sensors and in particular an approach sensor 9 and a touch sensor 8.
  • the approach sensor 9 makes it possible to initiate communication between the identifier and the system embedded in the vehicle when the user approaches the vehicle while the touch sensor 8 is used to detect a voluntary action by the user. view of the vehicle lock.
  • the approach detection zone 12 associated with the approach sensor 9 is located between the opening 4 and the gripping element of the handle 2.
  • the approach sensor 9 is for example a capacitive sensor whose operation is based on the measurement of the variation of the electromagnetic field surrounding it. It has at least one detection electrode 10 whose shape makes it possible to define an extended and well-controlled detection zone located between the opening 4 and the gripping element of the handle 2.
  • the touch sensor 8 is also for example a capacitive sensor. It has a detection electrode 10 which allows detection on a precisely defined area 11 and located on the outer surface of the handle. This tactile detection zone 11 has a high sensitivity to a touching action.
  • a conductive coating which may be a chemical deposit such as a chrome plating, a paint, a primer for decorative coatings or even the material constituting the handle, causes a modification of the capacitive couplings existing between the detection electrodes of the different sensors and the surface of the handle.
  • This disturbance mainly related to the electrical conduction of the coating is reflected for the various presence sensors by a change in the shape of the presence detection zone and a consequent decrease in the sensitivity of the sensor.
  • the approach sensor As part of the approach sensor, there is a spread of the detection zone and a significant decrease in the detection distance around the handle. Far detection (a few cm) on approach is no longer allowed and the user must be in the immediate vicinity (less than 1 cm) or even in contact with the handle so that a detection can be made. Indeed, the conductive coating is a screen for the electric field lines of the approach sensor and the detection by electrical capacitance measurement is greatly reduced.
  • FIG. 8 a diagram showing the sensitivity S of the touch sensor 8 as a function of the extent of the electrode 10 in a single dimension is shown diagrammatically in FIG. .
  • Curve A in solid line shows that the sensitivity curve of the touch sensor for a handle made of electrically insulating material.
  • This curve A has a plate P whose extent E substantially corresponds to the extent of the electrode 10. On the sides, we see that the sensitivity decreases strongly.
  • Curve B in dashed line shows the sensitivity curve of the touch sensor for a handle having a conductive surface coating. It can be seen that the sensitivity curve is wider and that its maximum is greatly reduced compared with the curve A, which causes malfunctions of the sensor 8. Moreover, there is no longer a characteristic shape in a plateau, which means that the detection zone is spread out and not very well defined. This is a significant handicap from an ergonomic point of view.
  • this conductive coating causes a disturbance of the touch sensor due to the spreading of the tactile detection area on a large surface of the handle and consequently a significant loss of sensitivity of the sensor. The tactile detection is therefore strongly disturbed.
  • An object of the present invention is to overcome these disadvantages and to propose a solution for creating a new presence detection zone. easily accessible, ergonomic and compatible with a conductive handle or having a conductive coating on its surface, so that a tactile or tactile approach detection can be performed again.
  • the proposed solution consists in adding, between the detection electrode of the presence sensor and the place where it is desired to create this new detection zone on the surface of the handle, conductive means.
  • these conductive means are preferably more conductive than the disruptive coating.
  • the detection distance is increased to create a new, more controlled holding area, by conduction of the electric field lines generated by the sensor inside the handle towards slots presented to the surface of the latter.
  • the initial detection zone of the touch sensor is then offset by a capacitive coupling and electrical conduction phenomenon to the point where it is desired to create this new detection zone.
  • the subject of the invention is a door handle, in particular for a motor vehicle, comprising at least one presence sensor having at least one sensor for detecting the presence of a user at the level of said handle.
  • This handle is characterized in that it comprises conductive means having at least one proximal end connected, directly or indirectly by capacitive coupling, to said detection electrode and at least one distal end opening electrically isolated on the outer surface of the handle so as to create at least one new presence detection area of a user.
