Definitions

  • the invention relates to a door handle for a motor vehicle, comprising an approach sensor intended to operate with a hands-free access system fitted to the vehicle.
  • a vehicle equipped with a hands-free access system allows an authorized user of the vehicle to enter the vehicle without having to handle a key or remote control.
  • the recognition device of the hands-free access system triggers a user identification authentication procedure carried by the user in response to the detection by the approach sensor of the presence of the user. After authentication of the identification member, the recognition device triggers the unlocking of one or more openings of the vehicle. .
  • the object of the invention is to overcome this disadvantage.
  • the subject of the invention is a door handle for a motor vehicle, comprising an approach sensor intended to operate with a hands-free access system fitted to the vehicle, characterized in that it further comprises a touch sensor also operating with the hands-free access system, the approach sensor for unlocking the doors of the vehicle by the hands-free access system, and the touch sensor for locking the doors of the vehicle by the parking system. hands free access.
  • the approach sensor and the touch sensor are capacitive sensors, and said sensors operate with the hands-free access system through an electronic circuit that activates each of said sensors one after the other, so that these sensors do not move. do not disturb each other.
  • this type of sensor the manufacturing cost of such a handle is reduced while avoiding the disadvantages of optical sensors.
  • the electronic circuit and said sensors are integrated in a housing mounted inside the handle.
  • the electronic circuit is arranged to alternate first periods of time during which it activates the approach sensor and deactivates the touch sensor, with second periods during which the approach sensor is inactive, and to activate the touch sensor during some of said second periods. In this way, the power consumption of the circuits in the handle is reduced.
  • the electronic circuit is arranged to activate the touch sensor at least a second period in five, and thus a satisfactory compromise between consumption and reaction time of the touch sensor is obtained.
  • the electronic circuit in response to the detection of a touch of the hand applied to the touch sensor during one of said second periods, activates the touch sensor for a predetermined number of seconds. second successive periods so that the detection corresponds to several successive detections of a contact applied to said touch sensor.
  • the electronic circuit ensures that the solicitation of the touch sensor corresponds to a voluntary contact of the user on the sensor and not the stealthy passage of his hand on this sensor.
  • the handle according to the invention comprises an electronic circuit CE represented on the figure 1 , which is connected to an AC approach sensor and a CT touch sensor.
  • This electronic circuit is directly powered by a battery of the vehicle to which it is connected by cables marked + and -, and it comprises a microcontroller clocked by an internal clock so that it is able to drive both AC sensors autonomously. and CT.
  • This circuit has two outputs SA and ST connected to a recognition device of the hands-free access system of the vehicle (not shown) to operate with the latter.
  • the cables are joined at a connector CN intended for example to be placed on the inside of the PE skin of the opening, as shown in FIG. figure 2 .
  • the circuit CE When the user approach is detected by the circuit CE at the AC sensor, this circuit sends a signal on the SA channel, and when a user support on the touch sensor CT is detected, the circuit emits a signal on the ST channel.
  • the recognition device is programmed to trigger an authentication attempt as soon as a user's approach is signaled to him on the SA lane, and to control the unlocking of the sash if the authentication attempt is successful.
  • the recognition device comprises means for controlling the locking of the sash when the support of the user on the touch sensor CT is reported to him on the track ST by the circuit CE.
  • the handle PO according to the invention may comprise the sensors and the circuit assembled in a substantially parallelepiped-shaped housing BO built for example at the inside of the handle.
  • the approach sensor and / or the tactile sensor of the circuit according to the invention may advantageously be capacitive sensors, consisting of an electrode also called antenna which is energized with respect to the mass of the vehicle.
  • capacitive sensors consisting of an electrode also called antenna which is energized with respect to the mass of the vehicle.
  • the approach of the hand of the user varies the dielectric characteristics of the environment of the sensor, which changes the impedance of the dipole formed by the electrode and its environment.
  • Such sensors are known from the prior art and are for example of a simpler implementation than the sensors associating a photocell with a light beam.
  • the approach sensor of the handle according to the invention is a capacitive sensor having a greater sensitivity than the touch sensor.
  • the electronic circuit CE is arranged to activate (switch on) the sensors one after the other so as to prevent the operation of one of the sensors disturbing the operation of the other.
  • the CE circuit can activate the touch sensor and the approach sensor successively, with an activation period of the order of five milliseconds per sensor. With such a time base, the two sensors have an operation that can be approximated as being continuous for one and the other, without mutual disturbance.
  • the circuit CE will be arranged to alternate first periods P1 during which it activates the AC approach sensor and deactivates the touch sensor CT, with second periods P2 during which the approach sensor is inactive.
  • the touch sensor is activated only during some of the second periods P2, which gives a shorter reaction time to the approach sensor CA which is intended for unlocking the door, and a longer response time to touch sensor, for locking the vehicle. It is indeed important to promote a quick reaction time for unlocking the door, so that the user does not have to wait between the moment he puts his hand on the handle and the moment he can pull top to open the opening and ride in his vehicle.
  • the touch sensor may for example be activated every five seconds periods, which satisfies a satisfactory compromise between reducing consumption and reaction time of the touch sensor.
  • the electronic circuit activates the touch sensor for a predetermined number of second successive periods.
  • the detection corresponds to several successive detections of said contact on said sensor, which ensures that it is a voluntary support of the user on the touch sensor, not the stealthy passage of his finger on the sensor.
  • the handle according to the invention makes it possible to use two capacitive sensors to improve the ergonomics of the hands-free access systems.
