EP1083284B1 - Door handle arrangement for vehicle doorlocksystem with passive entry function - Google Patents

Abstract

The arrangement has a door handle bearing in two parts (10a, 10b), a pivotable, adjustable handle (6) that can be pivoted from a rest position into an actuating position and a switch (11) on the handle or bearing for detecting operation of the handle from its rest position. Movement of the handle causes displacement of an outer actuating lever (12) in a lock mechanism or an electric function to open the door. The movement of the outer handle is transferred to the outer actuating lever or opening switch with a delay.

Description

The invention relates to a door handle arrangement for a motor vehicle door locking system with passive entry function with the characteristics of the generic term of claim 1.

Conventional electromechanical motor vehicle door locking systems are known with radio remote control, but without passive entry function. at these classic motor vehicle door locking systems are operated by the operator a push button on the remote control module. This will make the Control electronics activate and immediately go through their reaction phase. Due to the distance of the operator when pressing the button of the Remote control module, the operator reaches the outside door handle on the Motor vehicle door with such a long time delay that the reaction phase the control electronics long completed and the motor vehicle lock has been unlocked. The operator opens by pulling on Outside door handle the motor vehicle door, the motor vehicle lock either mechanically opens, i.e. the pawl by moving the outer door handle is lifted, or opens electromechanically or pneumatically, a control signal from the outside door handle to the opening drive for lifting the pawl is released.

A motor vehicle door locking system with passive entry function, also "electronic Key "differs from that previously explained classic motor vehicle door locking system in that on the remote control module no handling, so no button press has to be made, to unlock the motor vehicle lock when approaching the motor vehicle. Rather, all of this happens by itself simply when the operator approaches to the motor vehicle.

A motor vehicle door locking system with a passive entry function is required for the control electronics a specific reaction phase, which is based on a start-up interval, to activate the system when the remote control module approaches, an authorization check interval, based on the operator the coding of the exchanged between the remote control module and control electronics Check signals for their authorization, and finally that actual interval of action in which the action takes place, in particular the Unlocking the motor vehicle lock is carried out. (Even when locking the motor vehicle door locking system, a corresponding Reaction phase needed. But this is less critical because of it the operator hardly notices.)

The duration of the reaction phase of approx. 150 ms is compared to conventional Motor vehicle door locking systems perceived as long if one the start-up interval only starts when the outside door handle is actuated. EP-A-927 803 and EP-A-916 789 deal with this problem. Such one Motor vehicle door locking system with passive entry function is also known from DE-A-197 52 974. From a door handle assembly for one such a motor vehicle door locking system is based on the teaching of the invention.

In the door handle arrangement of such a motor vehicle door locking system of course pulling the outer door handle when the reaction phase the control electronics has not yet been completed. requires the control electronics for going through the startup interval and Authorization check interval and finally the action interval in which the motor vehicle lock is unlocked, not substantially as 100 ms, the path of movement of the outer door handle is sufficient to move on its last Then already lifting the pawl and opening it to effect the motor vehicle door. Is the reaction phase of the control electronics however longer, an operator must pull the door handle a second time pull to open the vehicle door. That is called felt annoying because it is understood as a "malfunction".

Another approach is the start-up interval of the control electronics not to start only when the outer door handle is actuated, but already an operator's hand approaching the outside door handle to start the start-up interval. For this it is known on the outside door handle to provide a proximity sensor (DE - A - 197 52 974; DE A - 196 17 038), by which an operator's hand approaches already about 100 to 150 ms before the outside door handle is touched by the Hand grasped. The start of the start-up interval of the control electronics, so the "waking up" of the control electronics takes place so far before the actual one Pulling the outer door handle that the start-up interval and usually also that Authorization check interval are already completed when the outside door handle is actually moved by the operator's hand.

The use of proximity sensors in motor vehicle door locking systems the type in question presents various difficulties. On the one hand, the proximity sensors have a comparatively high one Quiescent current, on the other hand, it is difficult to have a stable, clear response threshold adjust. External influences such as rain, snow, dust and Dirt change the measured values, especially with capacitive proximity sensors very. Finally, with proximity sensors, the problem is through not to be overlooked they emitted electromagnetic interference radiation. Therefore, despite the difficulties discussed above, the motor vehicle door locking systems have with passive entry function, where only one Actuation of the outside door handle by the hand of an operator Start-up interval of the control electronics starts, considerable advantages.

The invention is based on the problem of a door handle arrangement for to specify a motor vehicle door locking system with a passive entry function, which offers the prerequisites that a longer reaction phase of the Control electronics not perceived by the operator as disturbing becomes.

The problem outlined above is with a door handle assembly Features of the preamble of claim 1 by the features of the characterizing Part of claim 1 solved. A second, secondary solution is the subject of claim 5.

In the inventive solution of claim 1 is practically the maximum Adjustment path of the outer door handle on the door handle arrangement has been enlarged so far that the outer operating lever of the motor vehicle door lock only is operated with a corresponding delay. The same applies to one Opening switch if the motor vehicle lock of the motor vehicle door locking system can be opened by motor. This also means a longer reaction phase of, for example, 150 ms for an operator concealed.

In the secondary solution of claim 5, the speed of movement of the outer door handle on the door handle arrangement is reduced. As a result, it takes longer for the outside door handle to reach the maximum adjustment range has covered, but as such the maximum Adjustment path in door handle arrangements known from the prior art can correspond. This also makes the operator noticeable Movement time for the outer door handle extended, which then just the lamination also allowed a longer reaction phase.

Preferred refinements and developments of the teaching of the claim 1 are the subject of claims 2 to 4, the teaching of the sibling Claim 5 Subject of claims 6 to 9.

The motor vehicle 1 shown schematically in FIG. 1 has a motor vehicle door locking system on where the various motor vehicle locks 2 for motor vehicle doors and motor vehicle flaps schematically with their Installation positions are indicated. Each motor vehicle lock 2 is motor-driven, preferably by electric motor, unlockable and lockable. When running as an electric lock, as shown here, the motor vehicle lock 2 additionally the possibility of a motorized opening, i.e. lifting the pawl by means of an opening drive. In this case unlocking and locking can only be done by circuitry. Another variant is also the equipment of the motor vehicle locks 2 with an auxiliary locking drive that is identical to or from the opening drive this can be separated. In addition, the state of the art be referred (DE - A - 196 29 709 etc.).

Control electronics 3 are indicated in the motor vehicle door locking system is indicated here as central control electronics, but it is also decentralized to everyone the motor vehicle locks 2 can be assigned. It is planned to continue a hood lock 4 to be operated by means of a key for the bonnet of the motor vehicle and a remote control module 5, the passive Entry chip card is executed. The control electronics 3 cooperate overall a passive entry function, ie with an "electronic key". In this respect, too, reference may be made to the prior art mentioned above become.

The motor vehicle body can be recognized by the respective motor vehicle door an outside door handle 6 and on the driver's door a lock cylinder 7 for an actuation with a mechanical key 8, such an actuation in an emergency (emergency release and, if necessary, emergency opening).

As already explained for the prior art forming the starting point has to be taken into account with this motor vehicle door locking system, that the control electronics 3 have a reaction phase with a start-up interval, Authorization check interval and action interval, especially for unlocking of the motor vehicle lock 2.

It has already been realized in the prior art that the start-up interval of the control electronics 3 is started by the hand of an operator touches the outside door handle 6. "Operation" of the outer door handle 6 means real mechanical actuation or already touch. Fig. 2 shows a typical Door handle assembly 9 of a motor vehicle door locking system in question standing type with the outside door handle 6 and the lock cylinder 7.

Fig. 2 in conjunction with Fig. 3 now leaves a first preferred embodiment a door handle arrangement 9 according to the invention for a motor vehicle door locking system with passive entry function. One recognises First, a door handle bearing 10 firmly attached to the motor vehicle door in the illustrated embodiment consists of two bearing parts, namely a bearing part 10a, which also includes the lock cylinder 7, and a bearing part 10b, which contains the pivot bearing of the outer handle 6. The outside door handle 6 is adjustable on the door handle bearing 10, in the illustrated and preferred Embodiment pivotally mounted. The swivel bearing can not only about a vertical axis as in the illustrated embodiment, but also around a horizontal axis as in the prior art DE - A - 197 52 974 can be realized. Other adjustment constructions too for the outside door handle 6, for example also a push handle or a slide lever are conceivable.

The prerequisite is that the outer door handle 6 relative to the door handle bearing 10 from a rest position by a maximum adjustment range to an actuation position is adjustable. On the outside door handle 6 or on the door handle bearing 10, in Embodiment shown on the bearing part 10a of the door handle bearing 10 a switch 11 is arranged, the actuation of the outer door handle 6 from the Rest position detected.

The switch 11 is an electromechanical in the illustrated embodiment Microswitch, any other form of switch, for example, too Non-contact switches such as Hall sensors can be used here become.

In the illustrated embodiment, it is provided that by the adjustment the outer door handle 6 an adjustment of an outer operating lever 12 a lock mechanism for opening the motor vehicle door. Is to here the outer door handle 6 is assigned a coupling element 13, which the outer operating lever 12 of the lock mechanism. For such constructions may be referred to the state of the art.

The coupling element 13 need not have the hook shape shown in FIG. 3, it can also have the form of a rotary transmission element or the like. Various Solutions for the mechanical coupling of the outside door handle 6 to the lock mechanism are known in the prior art and can also in the present case.

Another, from below in connection with the embodiment Fig. 6 explained variant consists in the adjustment of the outer door handle 6 trigger an electrical function for opening the motor vehicle door. In this case, pure electric lock, the adjustment movement of the outer door handle 6 detected only by means of switches and in electrical drive movements for example, an opening drive implemented.

3 to 5 show that, according to the invention, the adjustment movement of the outer door handle 6 with a delay on the outer operating lever 12 is transmitted. It can be seen that this delay in transmission is realized in that a lost motion connection 15 between the outer door handle 6 and the outer operating lever 12 is realized in construction. A lost motion connection 15 can be provided, for example, by an elongated hole arrangement, a toggle lever arrangement or the like can be realized. Is particularly compact a lost motion connection 15 is realized as in the illustrated embodiment when it is designed as a telescopic connection. That the outside operating lever 12 assigned telescopic member 16 of the lost motion connection 15 does not move here until at least one further telescopic member 17 has covered a maximum adjustment distance. It is recommended that the lost motion connection 15, in particular the telescopic connection, with a spring element 18 is biased into the rest position.

3 to 5 show the sequence when actuating a door handle arrangement 9 of the type described here:

3 shows the outer door handle 6 in its rest position on the door handle bearing 10. If the outer door handle 6 is now pulled, the transition according to Fig. 4. It can be seen that first the microswitch 11 on the door handle bearing 10, namely on its bearing part 10a, immediately after actuation of the outer door handle 6 is operated. The switch 11 starts the reaction phase of the control electronics 3. While the outer door handle 6 is moving, the Control electronics 3 the start-up interval, the authorization check interval and finally the interval of action - unlocking the motor vehicle lock 2 - from. While moving the outside door handle 6 over a first part of it Adjustment path is only the telescopic member 17 on the outside door handle 6 itself moves, the spring element 18 is tensioned. In the transition from FIG. 4 5, since the telescopic member 17 has reached a stop, the telescopic member 16 connected to the outer operating lever 12 moves, until the outer door handle 6 then reaches its maximum adjustment path in FIG. 5 Has. The transition from FIG. 4 to FIG. 5 represents the adjustment path of the outer operating lever 12. On the last piece of movement of the outside operating lever 12 is the reaction phase of the control electronics 3 completed, the motor vehicle lock 2 is unlocked, the motor vehicle door is ultimately by the movement of the outer operating lever 12 open.

If you want a corresponding concealment of the delay time for the reaction phase the control electronics 3 with a pure electric lock, the outer actuation lever 12 is thus omitted. As indicated in FIG. 6, in addition is here by moving the outer door handle 6 over the switch 11 triggered the granting of access authorization. Then takes place the signal of an opening switch 14 and the access authorization is granted the function "open by wire", in particular that Lifting the pawl initiated by an auxiliary opening drive.

6 shows a further exemplary embodiment of an inventive one Door handle arrangement 9, characterized in that the adjustment movement of the outside door handle is slowed down by means of a braking device 20 becomes. Here the adjustment path of the outside door handle 6 is not artificial extended and thereby conceals the reaction phase of the control electronics 3, but the adjustment of the outer door handle 6 is deliberately slowed down. The braking device 20 can also be used with the previously explained Combine telescope arrangement of the first embodiment.

The embodiment of a braking device shown here is particularly expedient 20 if they do the adjustment movement of the outer door handle 6 slows down, but the required actuation force is not or only insignificantly increased compared to conventional outside door handles. The can be achieved, for example, by using the braking device 20 as a viscosity brake. That is in the illustrated embodiment realized in that a drive wheel 21 designed as a viscosity brake Braking device 20 with a rack 22 on the outside door handle 6 combs and rotates when pulling the outer door handle 6 becomes. Inside the brake device 20, an impeller is one of them Oil bath or other viscous medium driven. This will make the Adjustment movement of the outer door handle 6 slows down because the necessary Operating force with increasing the adjustment speed of the outer door handle 6 increases dramatically. So an operator becomes normal Pull on the outside door handle 6 to adjust the outside door handle 6 much more slowly than with classic door handle arrangements.

In the latter embodiment it is of course also recommended to provide a spring element for resetting, with the rest should provide that between the braking device 20 and the outside door handle 6 a freewheel is provided for the return movement of the outer door handle 6 is.

The two previously described embodiments of an inventive Door handle assembly 9 are both characterized in that they are in the direction of the adjustment movement of the outer door handle 6 only one relative have shallow depth. This facilitates installation in modern motor vehicle doors with a window guide near the outer skin of the motor vehicle door. In both alternatives of the invention, the required one is reached Laminating the reaction phase of the control electronics 3 without inside Motor vehicle door to need an excessively large adjustment. The latter would also be for the normal arrangement of an external operating lever 12 hardly feasible within the lock mechanism.
