Description

The invention is based on the object defined in the preamble of claim 1, which is known per se.

The invention was developed especially for an arrangement that is to be used in a four-door motor vehicle that contains such a motor-driven window in each door. However, it was found that the invention is also applicable to other arrangements falling under the generic term mentioned.

So far, the disadvantage has been the relatively high outlay for wiring such windows which can be controlled by motor drive.

It is known per se in the field of motor vehicle electronics to control a plurality of decentralized units by means of central electronics.

It is also known per se in the field of motor vehicle electronics to close a window in a motor-driven manner by actuating a switch in accordance with the closing command and to avoid using a sensor associated with the relevant window or motor that a person is protected against being caught in the closing window is. For this purpose, the motor in question can be braked by the sensor or the direction of rotation of the motor can be switched. The switches in question can also be switched by individually assigned signal transmitters, e.g. Rocker arm, operated remotely, such signaling devices also together in a central console, e.g. between the driver's seat and the front passenger seat.

The so-called tip function of switches is also known per se. This means that pressing a switch, i.e. immediately releasing it, triggers an activity that is still carried out despite being released. Such typing functions are e.g. previously known for the relevant switch of the motor-driven driver's door window. So far, however, the relatively high outlay for wiring such windows that can be closed by tapping has been disadvantageous.

• - bei allen solchen motorantreibbaren Fenstern des Fahrzeuges eine Tippfunktion zu ermöglichen, ohne den Aufwand für die Verkabelung zu erhöhen,

wird erfindungsgemäß durch den im Patentanspruch 1 definierten Gegenstand gelöst.The task,

• to enable a typing function in all such motor-driven windows of the vehicle without increasing the effort for the wiring,

is solved according to the invention by the subject defined in claim 1.

The invention is therefore particularly easy to apply to those types of vehicles whose motor-driven windows already have a sensor-controlled pinch protection, which in turn e.g. by monitoring the rotational behavior or the current consumption of the motor that is assigned to the window in question. The invention is therefore based on a skillful joint use of the sensors which then exist anyway and which detect the rotational behavior or the current consumption of the motors in question, as a result of which in the invention there is no need for additional cabling between the central electronics on the one hand and the motors and sensors in question.

The invention is also particularly easy to apply to those types of vehicle with motor-driven windows which already contain central electronics, albeit for other purposes, but which can also be used for the invention. Because central electronics anyway generally have a processor, e.g. contains a microprocessor, and because such processors generally already contain a large number of unused own memory elements - generally much more memory elements than the processor needs to store control software for its operation - the invention is therefore generally based on the joint exploitation of then there are usually excess memory elements of the central electronics.

The additional measures defined in the subclaims allow additional advantages to be achieved. Among other things, namely allow the measures according to claim

2, to avoid that accidental pinching becomes a prolonged pinching,

3 that the sensor, by acting directly on the direction of rotation of the motor in question, prevents pinching for a longer period of time even if the central electronics are defective and therefore could in turn no longer cause the direction of rotation of the motor to change,

4, to be able to close and / or open the window in question even in a motor-driven manner if the central electronics are defective, i.e. if e.g. whose memory elements are defective, and

5, automatically close all windows when the vehicle is locked centrally.

The invention and further developments of the same are further explained on the basis of the exemplary embodiment of the invention shown in the figure.

The figure thus shows an example of an arrangement according to the invention, which can be used to close and open individual motor-driven windows F of several such windows F of a vehicle. The arrangement thus serves e.g. for actuating one door window F of a four-door motor vehicle with such a window F in each door, cf. the front right and left doors FR and FL, as well as the rear right and left doors HR and HL with their motor-driven windows F.

Each door has FR, FL, HR, HL a motor M, a sensor S and a switch T. In the example shown, there are a plurality of signal transmitters X in a central console U, including the child lock K attached there for the rear windows F, these signal transmitters X also representing switches X here, which are individual individual of the motors M are assigned to the different windows F. These switches T and / or X represent, for example, rocker switches which can be moved by hand from a middle rest position into a left and a right switching position, namely a position for resting, for opening and for closing the assigned window F Triggered by such switches T and / or X individually assigned to motors M, these motors M can therefore be operated in the desired direction of rotation, that is to say forward and backward, in order to close and open the assigned windows F.

Each such window F is also individually assigned sensors S, which monitor the rotational behavior of the motor M assigned to this window F, i.e., e.g. recognize its direction of rotation, current consumption and / or torque. Above all, these sensors S also serve to recognize from the rotational behavior of the associated motor M in question whether a dead or living object, e.g. the finger of a person or the neck of a child is pinched by the motor M in the closing window gap.

The central electronics Z, which e.g. can contain a microprocessor Z controls the motor movements via its motor connections M1 to M4. When a vehicle occupant triggers the closing of the window F of his door by means of a switch T of his door - or if a vehicle occupant by means of a corresponding switch X in the console U - in the invention, the central electronics Z receives and monitors the output signals of the respective window F in question assigned sensors S and thus the rotational behavior of the motors M in question so that the object, for example the finger of the person is protected against strong pinching. If, in fact, the sensor S reports to the central electronics Z that the motor rotation behavior indicates a pinching, then the central electronics Z can e.g. brake immediately or even immediately switch its direction of rotation; the central electronics Z can even brake automatically after switching the direction of rotation if necessary only after a preprogrammed reopening of the window gap. If the sensor assigned to the window in question detects a pinching during the closing of the window and if the central electronics Z then switches the direction of rotation of the motor M in question, then it can be avoided that an inadvertent pinching becomes a longer lasting pinching.

Incidentally, it is also possible with the invention that the sensor S acts directly on the switch or the switches T and / or X of the motor M assigned to this window F when it jams an object in the closing window gap in such a way that it changes its direction of rotation, So it goes from closing to opening the window. In this development of the invention, the sensor therefore does not reverse the direction of rotation of the motor M in question by means of the central electronics Z, but rather directly by acting on the switch which determines the direction of rotation of the motor M, cf. T and X. In this way, the sensor S by means of the motor M in question can avoid a prolonged jamming even if the central electronics Z is defective and therefore could in turn no longer cause the direction of rotation of the motor M.

Furthermore, the figure shows schematically the wiring V between the motors M and the sensors S on the one hand and the central electronics Z on the other.

The central electronics Z in the invention, however, also contain, above all, a plurality of memory elements G which are individually attached and / or combined in a memory G and which are individually assigned to the switches T and / or the corresponding switches X in the console U. These storage elements G store the closing command given by tapping in the invention after tapping the relevant switch T and / or after tapping the corresponding switch X in the console U, that is also after releasing the respective switch T or X. Either by tapping itself, or at the latest by storing the signal corresponding to the tapping in the assigned memory element G, the motor M is first put into operation.

Subsequently, the motor operation is continued by this signal stored in the storage element G: when the window F in question is closed, the storage element G of the central electronics Z in question maintains engine operation until the sensor S assigned to the window F in question to the central electronics Z either the end of the Closing or pinching the object or person reports. If, on the other hand, the window F is opened by tapping, then the relevant storage element G of the central electronics Z maintains engine operation, for example until the sensor S assigned to the relevant window F or another sensor S assigned to this window F or motor M - reports to the central electronics Z the end of the opening.

The invention thus enables, by means of the storage elements G and by means of the sensor S of the motors M in all such motor-driven windows F, a tip function of those switches which trigger the closing and opening of the windows F with little effort at a central point. In order to achieve the tip function of the switch according to the invention, in comparison to an arrangement without a tip function, but with anti-trap protection, no increase in the effort for the wiring V is necessary. The invention is therefore particularly advantageously applicable to vehicle types which already have a pinch protection controlled by central electronics Z, which in turn is achieved by monitoring the rotational behavior of the motors M assigned to the windows F in question by means of corresponding sensors S assigned to these motors M. . The invention is then based precisely on a skillful utilization of sensors S which detect the rotational behavior of the motors M in question without additional effort for the cabling between the central electronics Z on the one hand and the motors M and sensors S concerned on the other.

Because the central electronics Z generally have a processor anyway, e.g. contains a microprocessor, and because such processors generally already contain a large number of unused own memory elements G - generally much more memory elements G than the processor needs for storing control software for its operation - the invention is then based on a clever one Using these then excess memory elements G of the central electronics Z.

If the central electronics Z does not additionally contain the control of the central locking of the vehicle, then the central electronics Z may also have connections W for cooperation with a central locking control unit located elsewhere, e.g. so that all windows F are automatically closed as soon as the vehicle is locked centrally. As soon as this vehicle is locked centrally, the control unit of the central locking in turn writes into the relevant storage elements G of the central electronics Z the same state that is written into these storage elements G when the switch for closing the window F is pressed, whereupon the central electronics Z closes the window F causes. The control unit of the central locking system can also write that corresponding state into the storage elements G for automatic closing of all windows F if the control unit is installed within the central electronics unit Z and possibly even if this control unit and the central electronics unit Z use the same microprocessor .

In addition, this central locking Z can contain further connections, e.g. the connection C for cooperation with the ignition lock so that the windows F can only be opened as long as the ignition key is in the ignition lock.

However, in the invention, the relevant switches T and / or X can additionally be connected to the vehicle battery or to the vehicle electrical system in such a way that the motors M are always operated in the desired direction of rotation - for opening and / or only for closing - as long as the relevant switches are operated. If the central electronics Z is defective, e.g. if the relevant memory element G is defective, which should actually save the tapping of a switch T and / or X assigned to the window F, then one can no longer achieve this by tapping, but at least by constantly pressing the relevant switch, that despite defective central electronics Z the window F in question can at least still be closed by constantly actuating the switch in question, possibly also to be opened.
