Definitions

  • the invention relates to a door handle and a locking system for a vehicle door according to the preambles of claims 1 and 10.
  • Such a handle arrangement for a motor vehicle is known for example from DE 100 57 019 AI.
  • a door handle arranged on the outside of a door is pivotably mounted on a carrier part arranged in the interior of the door.
  • the door handle has a driver which actuates a release lever of a door lock arranged in the door to open the door handle when the door handle is opened inside the door.
  • DE 196 17 038 C2 describes a locking and driving authorization system in which at least one electrode is installed in the handle of the door handle and in which a part of the door opposite the handle is fitted with a counterelectrode which also applies to the door can be yourself. 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 a hand that reaches for one of the handles on the doors already ne changes in the capacity built up between the two electrodes. Electronics, which perceive the change in capacity and translate it into a command impulse, are included in the handle of the door handle to save space. The command pulse generated by this electronics triggers the query of a 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 vehicle is secured by moving your hand past the side of the handle facing away from the vehicle. The locking and unlocking process of the vehicle is thus made pleasant and comfortable for the person authorized to access.
  • KEYLESS-GO An electronic driving authorization system called KEYLESS-GO, which works without mechanical or electronic keys, is also used in the applicant's vehicles. Its functions are carried out by a thin chip card in the format of a conventional EC or credit card.
  • the advantage is that drivers do not have to hold a key or card in their hands before boarding - it can always be kept in a shirt or jacket pocket.
  • the door handles are equipped with touch-sensitive sensors and the trunk lid with a special button. As soon as the driver touches a door handle or presses the button on the rear, his chip card receives signals from inductive antennas, which are housed in the doors and in the rear bumper of the vehicle. The card then sends an identification code to the vehicle by radio.
  • the vehicle owner can get in immediately or open the trunk lid.
  • the inductive data transfer takes only a fraction of a second. To secure the vehicle after exiting it is sufficient to press a button on the door handle or on the trunk lid. to activate the inductive antennas.
  • the system immediately exchanges data with the chip card, which is saved for later unlocking, and then secures the vehicle.
  • the invention is based on the object of making access to a vehicle more convenient and reliable.
  • a sensor for detecting a deflection of the door handle that is caused manually relative to a vehicle door is arranged in a door handle, with which a vehicle function can be triggered electrically when a predetermined deflection value for the door handle is reached. All you have to do is pull and pull the door handle to activate the electrically triggered vehicle function. A predetermined deflection of the door handle, for example of 1 cm in relation to its rest position, is sufficient as a triggering moment for the vehicle function. All vehicle functions that make it easier for the authorized person to get in are possible as an electrically triggerable vehicle function.
  • the vehicle function can include, for example, a comfort opening function which allows the person authorized to access to get in with only a small mechanical effort.
  • the vehicle function that can be triggered by the deflection of the door handle is a locking system function, in particular a quick-release function.
  • This will unlock the Vehicle door is not made by a central locking system, which could prove too slow when trying to open the door quickly.
  • the vehicle door would not have been unlocked by the central locking system during an opening phase following the unlocking phase and could not be opened in the opening phase.
  • the vehicle door can be unlocked and opened in one movement. A vain pull on the door handle for a targeted opening of the vehicle door due to a still locked vehicle door is avoided. The vehicle door is reliably unlocked before it is actually opened, regardless of the opening speed.
  • the vehicle door can jump from its closed position to a slightly open position during the opening phase due to a mechanical door preload.
  • the person authorized to access now only needs to pivot the vehicle door into the desired position.
  • the present locking system proves to be extremely convenient and user-friendly due to a time advantage when opening and a simplified functionality.
  • the door handle has a driver at one end which actuates a door lock arranged in the interior of the vehicle door when the door handle is opened
  • the sensor is arranged in the area of the driver.
  • the sensor is inside the vehicle door when it is closed the vehicle door, in particular in the interior of the door lock assigned to the respective vehicle door. This makes it particularly easy to detect the deflection of the door handle.
  • a servo motor is activated in the door lock assigned to the vehicle door to quickly unlock the door lock.
  • the servo motor ensures timely unlocking of the vehicle door.
  • the section of a vehicle shown in the figure illustrates a partially shown vehicle door 2 with a locking system 4, which comprises a door handle 6 attached to the outside of the vehicle door 2.
  • the door handle 6 is pivotally mounted at one end 8 and has a driver 12 at its other end 10, which actuates a door lock 14 arranged in the interior of the vehicle door 2 and indicated in the figure when the door handle 6 is opened.
  • a sensor 16 for recognizing a deflection of the door handle 6 relative to the vehicle door 2 is arranged in the area of the driver 12, the deflection being caused manually by an authorized person.
  • the senor 16 can also be used in other areas of the door handle 6, in particular in the central area of the door handle 6, can be accommodated, wherein the door handle 6 itself can have other embodiments with differently designed deflection mechanisms.
  • the sensor 16 is designed as a capacitive sensor, as a Hall sensor, as a reed contact or as an acceleration sensor.
  • the path length of the deflection of the door handle 6 is determined by double integration over time via the acceleration of the door handle 6 that occurs when the vehicle door 2 is opened.
  • a capacitive unlocking sensor 18 for unlocking the vehicle door 2 can be arranged via a central locking 22 in the area of the door handle 6, in particular in the area facing the door.
  • the hand grips behind the door handle 6 and reaches the sensitive area of the capacitive unlocking sensor 18.
  • the unlocking sensor 18 recognizes the hand and first triggers an identification code request in a known manner in an access authorization system an inductive data transfer between the vehicle and a chip card carried by the authorized person. After a positive identification code request, a conventional unlocking function 20 of the vehicle is triggered automatically via the central locking 22.
  • the door handle 6 is deflected by the authorized person after reaching behind it.
  • the unlocking with the aid of the central locking 22 often proves to be too slow due to the technology, so that the vehicle door 2 cannot yet be unlocked and released for opening during a quick, targeted attempt to open it.
  • the sensor 16 triggers a quick release function 24 in the door lock 14 of the vehicle door 2.
  • a servomotor arranged in the door lock 14 is provided for quickly unlocking the vehicle door 2.
  • the sensor 16 controls the servo motor arranged in the door lock 14 via a control unit 26 integrated in the door handle 6 and via the central locking 22 and activates the quick-release function 24.
  • the quick release function 24 of the vehicle door 2 is triggered when the predetermined deflection value for the door handle 8 is reached within a predetermined period of time after actuation of the unlocking sensor 18. This ensures that the vehicle door 2 actually unlocks before the actual opening even when the motor vehicle is opened in a targeted manner is. It is prevented that the door handle 6 is pulled "empty" by the person authorized to access it, since unlocking pins have not yet engaged and have not yet mechanically released the vehicle door 2.
  • the central lock 22 is used to unlock the door with the conventional unlocking function 20.
  • the quick-release function 24 is used not mandatory.
  • a required response time from pulling the door handle 6 to unlocking by the servo motor is less than 300 ms.
  • an acceleration sensor as sensor 16 to detect a manually caused relative to the vehicle door 2 th deflection of the door handle 6, instead of or in addition to the deflection of the door handle 6, the acceleration of the door handle 6 itself and / or its average speed, which is determined by simple time integration via the acceleration of the door handle 6 that occurs when the vehicle door 2 is opened, as Criterion for reaching a predetermined deflection value and thus as a trigger criterion for, for example, the quick release function 24 are used.
  • a lower threshold value can be specified for the average speed and / or for the acceleration, the quick-release function 24 being activated only above this lower threshold value.
  • the quick-release function 24 triggered by the sensor 16 ensures that the vehicle door 2 opens reliably and quickly, regardless of the reaction time of the pneumatics / mechanics of the central locking 22.
  • a capacitive locking sensor 26 for locking the vehicle door 2 can be arranged in the area of the door handle 6 facing away from the door.
  • this and / or the unlocking sensor 18 can be designed as a button.
  • the control unit 26 is also controlled by the unlocking sensor 18 and / or the locking sensor 28. The control unit 26 thus processes all sensor signals recorded in the door handle 6.
  • the unlocking sensor 18 is dispensed with and the unlocking of the vehicle door 2 takes place solely via the sensor 16.
  • the locking system 4 with the door handle 6 and whatever sensor 16 is configured can, in parallel or as an alternative to the quick-release function 24, other locking system functions, in particular a comfort opening function. believe it.
  • a comfort opening function for example, an almost powerless opening of the vehicle door 2 is provided for the authorized person, in which a mechanism integrated in the door lock 14 assigned to the respective vehicle door 2 mechanically moves the catch 12 of the door handle 6 when the predetermined deflection value for the door handle 6 is reached for an almost powerless one Opening the vehicle door 2 releases.
  • the vehicle door 2 can be opened without overcoming a mechanical resistance due to the lock.
  • the vehicle door 2 jumps towards the person authorized to access due to its mechanical pretension or is pushed out of its closed position with the aid of a motor.
  • the comfort opening function can be suspended, for example, in order to enable the door to be opened conventionally, for example for test purposes or if the comfort opening function fails.
  • the door handle 6 or the locking system 4 according to the invention ensures that the motor vehicle can be opened quickly, reliably and conveniently.
