BACKGROUND OF THE INVENTION

DE 32 43 111 32 discloses a central interlocking device in which an electromotive-driven two-pressure air pump supplies both the closing adjusting elements for the door and flap closures of the central interlocking device which is associated with the central interlocking tap of the device and other compressed air consumers, e.g. backrest cushions and pressure damping container in the comfortable turning of the device. The latter appliances are referred to as comfort appliances in the following description.

The two branches or branches of the device can be alternately connected via a switch valve to a pump outlet which provides either overpressure or underpressure depending on the direction of rotation of the pump. In this case, the valve is switched depending on the pressure demand space, i.e. with a convenience tap or with a central locking tap, whereby the central locking tap is generally preferred.

and; for hedging. SAFETY The central interlock branch has a central interlock pressure switch, an end pump cut-off after the unlocking process, but which serves to automatically stop the interlock or otherwise has no other control function.

^In contrast, the convenience tap of the device also includes a pressure monitor or pressure control switch, the essential task of which is to maintain the prescribed pressure level in this tap, if necessary, by electrically activating the pump and the associated switching valve.

In another known motor vehicle central locking device, which is known from 34 34 00 945 A1, at least one control switch and a pressure monitoring switch are provided to the electronic central control circuit for a pneumatic piping system for supplying the central locking action elements. devices and are evaluated by it.

In one embodiment, the known central locking device also has a pneumatic branch pipe, i.e. a comfortable branch for connecting at least one inflatable pad to the pump of the central locking device. Also in this pipe branch there is an electrically connected pressure monitoring switch connected electrically to the central control circuit.

The prior art parts of the independent claims are known in the art.

Recognizing that its switching signal is only generated in a regular manner in connection with the «activation of the pump by means of a control switch signal which is controlled by the vehicle user for centrally unlocking or locking the shutters, for example manually manually or by an internal switch; ovííc. from its button, it was deduced that any pressure without connection could be. ni ie;,; The switches can only be operated without introducing pressure or vacuum.

In this case, it is possible, depending on the direction of rise of the pressure switch, to reactivate the previously set state, i.e. the blocking or unlocking state, by activating the pump in the opposite direction.

This type of control effectively supports the vehicle's anti-theft protection, since it also acts to prevent the introduction of an illegal, for example unblocking, overpressure at any point in the piping system of the central locking device, since the pump engages to generate negative pressure or overpressure. if a vacuum is used to unlock.

it may also be expedient to connect to the central interlock pressure switch in addition to its usual switching point, which, after adjusting the central interlock actuators, for the final pump disconnection, another switching point with an absolute lower switching threshold such as an additional contact set or an additional pressure switch A switching unit is included in the sense of central locking, the switching threshold being later at the same time as the actuating elements rise, even when the pressure is increased or reduced. This additional switching point is then only possibly reached by the pump.

The pressure switch pressure switches are operated without the switching effect during normal operation of the central locking device.

Modern central locking devices are controlled by the central control circuit to which they are fed.

method, since the logical comparison operations required therefor can be created by corresponding programming.

It goes without saying that the apparatus for carrying out the method can also be implemented with discrete logic elements, electronic components, i.e. wiring and the like.

There is a baptism

Further details and advantages will become apparent from the following description of an exemplary embodiment in conjunction with the drawing.

an embodiment of the invention

The central locking device has a ce-tm.! ^{11 is a} control circuit 10 of its own power supply, from the on-board power supply of a vehicle (not shown), to which control signals 2 are connected via control input Zf and by control input EE unlocking signals from also control switches connected in parallel _3.

If one of the two switches is on, it welcomes the blocking of the vehicle control switches from the outside, such as the centering locking, divider switches 2 to which the central iiodon turns on • the reverse electric motor - also the two-pressure pumping draft for creating vacuum. This will vent the central locking piping system 6 to which the working chambers of the closing actuators (not shown) and the central locking pressure switch 7 are connected in the usual manner. The connected actuating elements are then moved from their unlocking position to their locking position.

In the said locking cylinder in the unlocking direction, the pump 5 is connected to generate an overpressure that moves the connected actuators from their locking position to their unlocking position.

It goes without saying that the central locking device can be operated from a plurality of locking switches 2 and / or 3 provided, in particular on the driver's door, the passenger door and the cover lid, which means that it is possible to operate from multiple locations. control input EE unlocking and control input EV window lockers · ;:

It is understood that bistable closing action elements can only be moved if they are exerted by a kind of pressure that counteracts the one that created the prior art. Even if the actuating elements are repeatedly subjected to the same kind of pressure, their position does not change even when the device is similarly formed, it is of course also possible to use a vacuum action to adjust the unlocking and a positive pressure action to adjust the lock.

The central locking latch switch 1 is electrically connected to the central control circuit 1. It then responds in the usual way to both negative and positive pressure in the central blocking piping system, if

environment; a simple plausibility test and / or a logic connection of the signal, for example by coupling the negation of the logic product, can be found to be undesirable for the user to act on the central blocking pipeline inlet.

It would be possible, for example, to input a signal or shingles, for example a flip-flop at each operation on one of the control switches 2 or 3, as long as the central blocking operation of the pump 5 is not terminated again by means of the central blocking pressure switch 2. and. _: . central lock signal 2 pressure switch signal.

In this regard, the scooter is taken into account that the operation of the central interlocking device always has priority over the supply of the convenience tap 9. In particular, the normal supply of the comfort tap is interrupted immediately as soon as the central control circuit 7 detects that one of the control switches 2 or J has given a signal.

As soon as the switching signal is released by the central locking pressure switch 2 without the switch signal being emitted from the computer memory, undesirable pressure action on the central locking pipe can be assumed without further delay.

In this case, it can be expediently examined whether the state of the closing actuating elements, i.e. the reset from the unlocked to the locked position or vice versa, can be undesired by the initial state at or before the triggering of the central locking pressure switch signal.

This check can be carried out due to the position feedback which, or from all the closures or the closure of the central control circuit 1, for example, is brought from the edible

ACTION ACTION: Disclaimers about the time period of the signal. However, it is also possible, for example, to memorize the start direction of the central locking pressure switch 1 at the last disconnection of the pump 5 than the newer signal of this control switch 2, 2,

If this is in the opposite switch, which arises without sig, it is necessary to re-establish the starting point in such a case that in the case of an undesirable central blocking piping system. ϋ unneeded state, eventually there could be no change required by any device reaction.

there is no melt-mixing effect on the meshes, even if, on the other hand, the central locking piping system d is exerted by a kind of pressure bv counteracting the one which ensured the formation of the current state, i.e. a negative pressure has been applied or a negative pressure has been created at the current blocking state, by logically connecting the electrical input signals of the central control circuit or its microprocessor, this undesired action can be counteracted by switching the switch valve S into its rest position and the pump 5, or its electric motor 4 is connected in the sense of restoring the previously set state of the closing actuators. This is finally confirmed by the restored signal of the central lock pressure switch 7.
