Definitions

  • the invention relates to a device for locking and unlocking a vehicle door according to the preamble of patent claim 1.
  • KEYLESS-GO an electronic driving authorization system
  • Its identification function is carried out by a thin chip card in the format of a conventional EC or credit card.
  • the door handles are equipped with touch-sensitive sensors and the trunk lid with a special button.
  • his chip card receives signals from inductive antennas, which are housed in the doors and rear bumper of the vehicle.
  • the card then sends an identification code to the vehicle by radio. If this matches the saved value, the cardholder can get in immediately or open the trunk ceiling1.
  • the inductive data transfer takes only a fraction of a second.
  • a locking system and driving authorization system is known from DE 196 17 038 C2, in which at least one electrode is installed in each of the handles of the door handles and in which a part of the door opposite the handle is fitted with a counter electrode, which also includes the door itself can be. If an electric field is established between the two electrodes, this can be used in an advantageous manner to already sense the access request of a person reaching for a door handle. This happens because one hand reaches for one of the handles located on the doors and, when they approach, already changes the capacity built up between the two electrodes.
  • the command pulse generated by this electronics triggers the query of the data carrier in the electrical control unit.
  • the locking system can be locked using a second sensor or button on the outside of the handle. The securing of the vehicle then takes place by moving the hand past the side of the handle facing away from the vehicle.
  • the invention is based on the object of specifying a device for locking and unlocking a vehicle door with a door handle attached to its outside, which brings a time advantage over the devices known from the prior art and has improved reliability.
  • the object is achieved by a device for locking and unlocking a vehicle door with the features of patent claim 1.
  • the triggering processes for the personal identification code request and the door unlocking are separated in time and location.
  • the identification code is requested by addressing the easily accessible identification sensor (e.g. a button or a capacitive proximity sensor) and then unlocking with the unlocking sensor that can be activated by reaching behind the door handle (e.g. a button or a capacitive proximity sensor). Due to the separation of the functions and arrangement of the sensors, the actual unlocking takes place much faster than in the devices known from the prior art.
  • the identification sensor To ensure that the identification sensor can be reached and triggered quickly by manual access, it should be located in an easily accessible area of the door handle, for example in its upper area or in its area facing away from the door.
  • the identification code request By separating the functions of identification code request and unlocking, only the identification code request can be carried out initially and unlocking can take place at a much later time, which also improves system security.
  • the capacitive identification sensor has a lower sensitivity than the capacitive unlocking sensor. In this way, unintended identification code queries are avoided. These unintentional trips are caused, for example, by weather-related influences such as water or snow on the door handle. A false triggering of the identification sensor is harmless since the actual vehicle door unlocking takes place in the second step with the unlocking sensor, which is not exposed to the weather conditions to the same extent as the identification sensor. It is advantageous if the identification code query can also be started with the unlocking sensor. This enables the identification code to be queried redundantly. In the event of a possible failure of the identification sensor, the identification code can still be queried.
  • the section of a vehicle shown in the figure comprises a partially shown door 2 and a door handle 4 attached to it on the outside.
  • the device for locking and unlocking the vehicle door comprises three capacitive sensors 6, 8, 10 inserted inside the door handle 4.
  • the capacitive identification sensor 6 is arranged in the upper inner region of the door handle 4. It is used to start an identification code query by an access authorization system (not shown).
  • the door handle 4 is covered in the area of the capacitive identification sensor 6 in an embodiment not shown by a chrome cover.
  • the capacitive unlocking sensor 8 is introduced in the area of the door handle 4 on the door side and can therefore only be activated by reaching behind the door handle 4.
  • the door 2 is unlocked with it.
  • a capacitive locking sensor 10 is arranged in the area of the door handle 4 facing away from the door for locking the door 2. Alternatively, this could be designed as a button.
  • an authorized person to open the door 2 first strokes his hand over the upper area of the door handle 4 and reaches the sensitive area of the capacitive identification sensor 6.
  • the sensor 6 recognizes the hand and releases it Access authorization system in a known manner from an identification code request, in which an inductive data transfer takes place between the vehicle and a chip card carried by the authorized person.
  • the identification sensor 6 can also be arranged on the side of the door handle facing away from the door, e.g. to be triggered by the ball of the thumb or the thumb of the hand gripping the door handle.
  • the sensors 6, 8, 10 are capacitive sensors in the interior of the door handle 4, any kind of effort switches that are located on the door handle do not apply Protect the ingress of dust, dirt and water.
  • the capacitive sensors 6, 8, 10 are cast after installation. The outside door handle is therefore optically indistinguishable from a door handle without additional functions.
  • the locking sensor 10 and the identification sensor 6 are functionally combined in a single combination sensor. This is possible because the locking function is never required simultaneously or immediately adjacent to the identification function.
  • the combination sensor can perform the identification function when the vehicle is locked and the locking function when the vehicle is open.
  • the combination sensor can be configured as' pushbutton or as a capacitive sensor.

Abstract

L'invention concerne un dispositif pour verrouiller et déverrouiller une porte (2) de véhicule, comprenant une poignée de porte (4) fixée sur le côté extérieur et un détecteur (6) de déverrouillage disposé dans la partie intérieure de la poignée de porte (4) côté porte, lequel est destiné à déverrouiller la porte (2), ladite porte de véhicule étant sécurisée par un système d'autorisation d'entrée électronique. Selon l'invention, un détecteur d'identification (8) est disposé, de plus, dans la partie de la poignée de porte (4), ce dernier permettant de lancer une interrogation du code d'identification, à l'aide du système d'autorisation d'entrée.
