Definitions
- the present invention relates to an electronic control circuit for a car door locking system and a car door handle with such a system.
- the present invention also relates to a car door handle with a cavity in which an electronic control circuit is housed.
- a car door locking system is unlocked by means of an electronic control circuit integrated in the car door handle, that is, from a state that prevents opening of the door or flap to a state that enables opening of the door or flap.
- a contactless portable data carrier for example in a chip card or in a key fob.
- the data query is triggered by a mechanical switching element, or by a proximity sensor, which triggers the forwarding of a data query to the external portable data carrier when a person approaches the handle.
- the data carrier for example a transponder
- the control circuit only releases the door when the identification is valid.
- Proximity sensors that use an infrared or ultrasound sensor system are known. They have the disadvantage of being very sensitive to dirt or external noise. Microswitches and pressure sensors have also been used, but they react late (when the user actually touches the handle). This delayed data query and the subsequent reaction time of the unlocking mechanism make such systems uncomfortable. In some cases, this means that the locking system at the first Actuation of the handle is not yet unlocked and the person requesting access has to touch the handle again to unlock the door.
- WO9741322 describes a system in which at least one electrode is installed in the handles and a counter electrode is attached in the part of the door opposite the handle. An electrical field is built up between the two electrodes, which is used to determine the access request of a person reaching for a handle. As soon as a hand is between the handle and the opposite part of the door, a data query is sent to the external data carrier. To send the data request, an electromagnetic transmitter-receiver with an induction coil is used in this system. The proximity sensor electrodes are formed by the induction coil and / or by the chrome-plated cover of the handles.
- this system has the disadvantage that it only reacts when a hand comes between the handle and the opposite part of the door, so only insignificantly before touching the handle.
- An object of the present invention is to improve the reliability of such a system.
- the reliability of the hand sensing depends on the condition of the proximity sensor electrodes. Dirt, water, snow, scratches or dents affect the capacity between the electrode in the handle and the electrode in the door. In some cases, this means that unwanted data queries are triggered or, conversely, that approaching hands are sensed too late, or under certain circumstances only after several attempts. It has also been found within the scope of the invention that the proximity sensor electrodes are disturbed by the induction coil and that disruptive charges arrive on these electrodes when a data query is sent, so that the capacitance between the proximity sensors and the earth is measured incorrectly.
- Another object of the present invention is to solve these problems and to offer an electronic control circuit which is less sensitive to scratches, dirt, water and electrostatic disturbances, in particular disturbances from the induction coil.
- an electronic control circuit for an auto door locking system which contains the following features: a control unit with at least one induction coil in order to forward a data query to an external contactless data carrier and to trigger the unlocking of the auto door locking system if a valid response is received from the named data carrier, a proximity sensor with at least one proximity sensor electrode to initiate the forwarding of said data query when a person approaches said proximity sensor electrode, said proximity sensor electrodes and said induction coil being housed in the exterior door handle of a car, an electrostatic shield between said proximity sensor electrode and said induction coil.
- This also has the advantage that a very sensitive proximity sensor can be used which can sense a person requesting access very early on and whose electrodes can be covered by a housing and / or a sprayed material, which provides additional protection against scratches, Allows dirt, water, damage and dents.
- Fig. 1 shows the handle of a pull handle and part of a vehicle door in cross section.
- Fig. 2 shows the control circuit shown in perspective
- Fig. 3 is a schematic of the electronic control circuit.
- Fig. 4 is a perspective variant of the control circuit
- FIG. 1 shows a vehicle door pull handle, which comprises an inner part 9 fastened to the vehicle door and a handle 7 designed as a bow handle.
- the handle 7 comprises a handle dome 70 which, with the end facing away from the handle 7, projects into the interior 90 of the vehicle door and is connected to the automatic door locking system, which is not shown for reasons of clarity.
- the auto door locking system is unlocked via the vehicle central locking system in order to free the handle dome 70 and thus the handle 7.
- the handle 7 can be pulled outwards to open the vehicle door.
- the handle 7 can be rotated about the joint 71 shown.
- the door could open automatically after recognition of a valid identification of the person requesting access.
- the electronic control circuit 1 is accommodated in the handle 7 in the handle 7 , which is intended to enable the authorized user to trigger the unlocking of the car door locking system in the most convenient way possible.
- the control circuit 1 is connected to the auto door locking system inside the vehicle by connecting cables 12. It is preferably powered by these connecting cables from the car battery. In the event of a power failure, the door can preferably be opened by means of a locking cylinder (not shown) with a key provided for such cases.
- the control circuit includes a touch sensor 22 which is a
- Signal triggers as soon as the user places a finger (especially a thumb) on the outer side of the handle.
- a proximity sensor 5 triggers another signal when a hand or another earthed object approaches, in particular in the case of a hand approaching the space between the handle 7 and the inner part of the handle 9.
- these signals are transmitted by a control unit 20 with a microcontroller and at least one induction coil 3 interpreted to forward a data query to an external contactless data carrier, not shown.
- the data carrier preferably consists of a transponder (which can be integrated, for example, in a chip card or in a key holder) and is "woken up" by this data query. If the data query is addressed to him, he responds with a response that includes an identification of the data carrier or that is signed with such an identification. The response is received by the electronic control unit 20 in the handle 7 in order to trigger the unlocking of the car door locking system if it contains the expected identification or if it was signed with this expected identification. In a further embodiment, the control unit 20 is only partially embedded in the handle 7.
- the control circuit 1 is described in more detail in connection with FIGS. 2 and 3. It comprises a printed circuit board 2 on which all components 20, 21, 22, 3,4,5, 120 are mounted.
- the circuit board 2 preferably has a thickness of 0.3 mm or less, but preferably of 0.2 mm or less, and is therefore flexible and less prone to breakage. It is housed in a synthetic insulating housing 13, which longitudinally fills most of the cavity 72 in the handle 7.
- the control unit 20 is mounted on the left-hand side of the printed circuit board 2, which comprises a plurality of electronic SMD components, including a microcontroller, mounted by a so-called reflow process.
- the connecting cables 12 are mounted parallel to the printed circuit board 2 on the right side thereof by the so-called auto-splice method.
- the main advantage of the Autosplice process compared to other soldering or fastening processes is that it is much less sensitive to shocks, vibrations and changes in temperature.
- a synthetic seal 121 (made of Santoprene or other elastomer, for example) holds the cables 120 in place and prevents moisture infiltration into the housing.
- the control circuit 1 also includes a contactless transmitter-receiver in order to exchange data with the external contactless data carrier.
- the contactless transceiver comprises a resonance circuit with an induction coil 3 and a capacitor 4, which are mounted directly on the printed circuit board 2, as shown schematically in FIG.
- the induction coil consists of a winding of an electrically insulated wire on a plate-shaped ferromagnetic ferrite core.
- the capacitance is preferably a ceramic or polypropylene capacitor with a value of approximately 3.3nF to 18nf, but preferably approximately 15 to 18nF. It is used to match the impedance of the transceiver to the driver stage of the microcontroller.
- the control circuit 1 also includes a proximity sensor with two proximity sensor electrodes 5 in this preferred example in order to sense people who are approaching the handle.
- the proximity sensor electrodes 5 are electrically connected to the control unit 20 such that the changes in capacitance between the proximity sensor electrodes 5 and the earth caused by the user body are sensed. When a (grounded) person approaches the proximity sensor electrodes 5, the capacitance between these electrodes and the earth is impaired.
- the control unit 20 preferably determines these small changes in capacity using a charge transfer measurement system, i.e. by switching the unknown capacity with a larger reference capacity via switches.
- the electrodes 5 each consist of a long, flat, electrically conductive plate on the upper side of the printed circuit board 2 or preferably along this printed circuit board. In this way, the movement of a hand between the bow-shaped outer part 7 of the handle and the vehicle door can be determined quickly and reliably.
- an electrostatic shield 21 is provided between the proximity sensor electrodes 5 and the induction coil 3. This shielding prevents, among other things, that the Measurement of the capacitance between the proximity sensor electrodes and the earth is disturbed by the induction coil 3 and that parasitic charges reach the sensitive proximity sensor electrodes 5. Since this interference factor is eliminated or at least significantly suppressed by the invention, the sensitivity of the proximity sensor can be increased without increasing the risk of incorrect proximity determinations.
- the shield consists of two electrically conductive metal plates 21 which separate the induction coil 3 from the two lateral proximity electrodes 5.
- the plates 21 are mounted perpendicular to and directly on the printed circuit board 2. They are preferably electrically connected to the ground of the circuit 1. If the available space, in particular the permitted height, allows it, the shielding could be made even more efficient; in particular, the circuit board could also be used as a shield.
- FIG. 2 shows a touch sensor 22 which is mounted on the printed circuit board 2 in such a way that contacts between the hand, in particular the thumb, the user seeking access to the vehicle and the outside of the handle can be determined (on this figure on the left side of the printed circuit board 2).
- the touch sensor contains a capacitance with an electrode on the outward-facing side of the printed circuit board 2 and another electrode on the inner side of the printed circuit board, which can consist, for example, of the basic interconnects on the assembled side of the printed circuit board.
- the capacitance of the touch sensor is preferably less than 5pF.
- the touch sensor also contains a capacitance measurement system to determine the capacitance changes caused by the user finger and to direct them to the named microcontroller.
- the control unit 20 and the touch sensor 22 are connected to the transmitter-receiver circuit and to the connecting cables 12 via conductor tracks on the printed circuit board 2. These paths run under the induction coil 3, possibly also on the other side of the circuit board and / or through inner layers.
- the circuit board 2 is accommodated in a synthetic housing 13 which extends substantially through the entire length of the cavity 72 in the handle part 7.
- the housing 13 and the proximity electrodes 5 are preferably slightly curved in order to adapt to the bowed shape of the handle part 7. Since curved ferrite cores are expensive and since problems with wire winding on a bow-shaped core can arise, only the two ends of the housing 13 are preferably curved, as can be seen in FIG.
- the core of the coil and thus the entire coil 3 is flexible. Since the circuit board is preferably so thin that it also has a certain flexibility, the adaptation of the control circuit to the bowed shape of the handle part 7 is considerably simplified. In addition, a flexible magnetic core is less breakable than a ferrite core. The reliability of the control circuit is thus significantly increased by reducing its sensitivity to the bumps that are unavoidable in a car door.
- the flexible core consists of several thin, flexible layers of magnetic material that are held together with flexible fasteners.
- the magnetic core is formed from an amorphous magnetic material, that is to say from a flexible casting compound in which small particles of a material with high permeability, such as ferrite particles, are cast.
- the magnetic core is in several parts. For example, it consists of several smaller parts made of a possibly hard magnetic material such as ferrite, which are connected together with a preferably magnetic flexible material.
- the circuit board 2 with all components is encapsulated in a thermoplastic insulating material which is injected into the cavity and which protects the components from moisture and dirt.
- a thermoplastic insulating material for example Macromelt
- a "hot melt” material for example Macromelt
- the thickness of the sprayed material along the longitudinal axis is therefore greater than at the two longitudinal edges in order to reinforce the structure where there is more space in the handle. It is also possible to reduce the thickness of the spray material above the electrodes 22 and 5 in order not to reduce their sensitivity.
- FIG. 4 shows a variant of the control circuit in which the proximity electrodes 5 are designed as part of the printed circuit board 2.
- a longitudinal cut is cut on both sides of the circuit board 2 not far from the two edges.
- the two separate lateral strips on the edge of the circuit board rise above the level of the circuit board.
- a longitudinal electrically conductive path is provided on each strip separated in this way, which is connected to the control unit 20 and acts as a proximity sensor electrode.
- the electrostatic shielding between the proximity electrodes on the two strips and the induction coil 3 is carried out by two electrically conductive metal plates 21 which are mounted perpendicular to the printed circuit board 2.
- this shielding by means of an interconnect electrically connected to the earth on the inside of each lateral strip of the printed circuit board 2.
- the outer interconnect acts as a proximity sensor
- the inner interconnect which is connected to the ground, serves as an electrostatic shield between this sensor and the induction coil.
- the distance between everyone Proximity sensor electrode and the corresponding shielding interconnect is considerably smaller than the distance between the electrodes and the ferrite core, so that the capacitive influence of the ferrite core on the proximity electrode only plays a minor role.
