Abstract

The method involves controlling at least one window raiser by operating a control element in the form of a hand crank. Operating the hand crank selects a panel to be moved by the relevant window raiser and the movement of the selected window panel is controlled by electric motor in respect of its movement direction and/or mode. Movement is controlled according to the position of the hand crank and/or its rotation direction.

Description

Electric drive units are versatile in motor vehicles for implementation of moving processes of moving parts (control elements) used, for example to adjust seats or to open and close Sunroofs, sliding doors and in particular from side windows of the motor vehicle. This Movements realized by an electric motor can be done manually continuous operation of controls by the operator or to increase the Comfort under certain conditions after the initiation of the Movement process automatically run by the operator (e.g. by one-off Operation of controls). In particular, these two modes of movement are in the operation of the power windows of motor vehicles implemented, the to control the movement processes (closing processes and opening processes) the window panes of the side windows of the motor vehicle are used. Usually, one is used to operate the electric windows Motor vehicle trained as a push button or push button control elements. however In the case of push buttons or push buttons, they can be actuated (triggered) or as a result of a lack of feedback on what is required to actuate (trigger) Force an arbitrary or uncoordinated control of the operator Electric windows are made, which is annoying or undesirable or too dangerous movements of the window panes of the side windows can occur.

The invention has for its object a method for operating the provide electric windows of a motor vehicle that a movement of the Window panes of the side windows in a simple way with nevertheless high Reliability enables.

This object is achieved by the feature in the characteristic of Claim 1 solved.

Advantageous further developments of the method are part of the further Claims.

The electromotive movement of the window panes of the side windows Motor vehicle (the front windows and the rear windows) is using controlled at least one control element designed as a hand crank, the one operator each (i.e. the driver of the motor vehicle and / or the passenger and / or other occupants of the motor vehicle) is assigned; d. H. at one of each operator made actuation of the trained as a hand crank Control element is assigned to at least one of these hand crank Front window and / or rear window by controlling the respective electrical Window lifter moved by an electric motor. By appropriate specifications or by corresponding boundary conditions in the case of operating a hand crank (e.g. with regard to the position of the hand crank after its actuation and / or the Duration of the operation of the hand crank and / or the direction of rotation when operating the hand crank and / or the rotational speed when actuating the Hand crank etc.) can change the sequence of movements and thus the movement of the respective Window pane can be controlled differently; in particular, the Window pane to be moved in each case (at least one front pane and / or Rear window) and the direction of movement of the one to be moved Window pane (opening or closing direction) and the Movement mode of the window pane to be moved (manual mode or automatic mode) be specified. When actuated, the respective hand crank can in particular either continuously rotated (the maximum angle of rotation of the hand crank is for example several full revolutions, e.g. four full turns) or by rotating or moving it once in a certain (axial or depending on the angle) (the maximum angle of rotation of the hand crank is for example a certain fraction of a full revolution, e.g. a quarter turn, d. H. 90 °).

The windows of the side windows of the motor vehicle to be moved (the Window panes of the front window and / or the rear window) can be used for Operation provided hand cranks can be variably assigned, with the Actuation of a hand crank at least the sequence of movements of this hand crank spatially adjacent window pane of the side window of the motor vehicle Motor vehicle is controlled. In addition, it can also be provided about the actuation of a hand crank the sequence of movements of several window panes control, especially by operating a hand crank on the driver's side Motor vehicle at least the movement of the two window panes To control the front window (the movement of the window pane of the Front window on the driver side and the window pane of the front window on the Passenger side) and possibly also the movement of the window panes of the Funds window. In particular, the window pane to be moved can be moved through Twisting or moving a hand crank selected in a certain position be, in particular by axially moving this hand crank in a certain Plane of rotation.

The sequence of movements of the window panes of the side windows of the motor vehicle can be activated in different ways by operating the crank handle Directions of movement take place either as an opening process (lowering the Window panes) or as a closing process (run-up of the window panes). In particular, can the direction of movement by the direction of rotation of the hand crank from the rest position the crank handle or by selecting a specific (in particular angle-dependent) position of the hand crank.

The sequence of movements of the window panes of the side windows of the motor vehicle can be activated in different ways by operating the crank handle Movement modes are either manual (as manual mode) or automatic (as Automatic mode), d. H. either the selected sequence of movements becomes so long executed how the hand crank is operated or the selected sequence of movements is automatically as long after corresponding actuation of the hand crank continued until the movement of the window pane is stopped (this can either by operating the crank handle again or by reaching the end position of the Window pane). In particular, the movement mode can be specified a certain, in particular, angle-dependent position of the hand crank can be selected or by the duration of the operation of the hand crank or by the speed of rotation when operating (turning) the hand crank.

• - Die als Handkurbel ausgebildeten Bedienelemente erlauben vielfältige designmäßige Ausgestaltungen (in vielen Kraftfahrzeugen sind aufgrund von Retrobewegungen wieder Stilelemente aus früheren Jahren oder Jahrzehnten implementiert) und sind vielen Bedienern von Kraftfahrzeugen in ihrer Funktionalität geläufig; daher und aufgrund der einfachen Bedienphilosophie (die Handkurbel ist einfach bedienbar, was eine einfache Steuerung des Bewegungsablaufs der Fensterscheiben ermöglicht) wird der Bediener intuitiv die richtige Betätigung der Handkurbel vornehmen.
• - Die Handkurbel ermöglicht auf einfache Weise eine haptische Rückmeldung an den Bediener, insbesondere wenn ein direkter Zusammenhang zwischen der Betätigung der Handkurbel und der elektromotorischen Bewegung der Fensterscheiben implementiert wird, insbesondere zwischen der für den Bediener erforderlichen Kraft zur Betätigung der Handkurbel und der elektromotorischen Bewegung der Fensterscheiben ("force feedback").
• - Alle bestehenden und gängigen Funktionalitäten von elektrischen Fensterhebern bzw. der Bewegungsabläufe von Fensterscheiben der Seitenfenster des Kraftfahrzeugs können auf einfache Weise realisiert und implementiert werden; insbesondere kann auch eine Automatikfunktion (der Automatikmodus als Bewegungsmodus) auf einfache Weise für den Bediener komfortabel implementiert werden.

Each time an operating element designed as a hand crank is operated to operate the electric window regulators of the motor vehicle, an efficient and comfortable movement sequence adapted to the current operating conditions of the electric window regulators can be realized with a high degree of reliability without restrictions on the operating options:

• - The control elements designed as a hand crank allow a variety of design configurations (in many motor vehicles, style elements from earlier years or decades have been implemented due to retro movements) and many motor vehicle operators are familiar with their functionality; therefore and due to the simple operating philosophy (the hand crank is easy to operate, which enables simple control of the movement of the window panes), the operator will intuitively carry out the correct operation of the hand crank.
• - The hand crank allows simple haptic feedback to the operator, especially if a direct connection between the operation of the hand crank and the electromotive movement of the window panes is implemented, in particular between the force required for the operator to operate the hand crank and the electromotive movement of the Window panes ("force feedback").
• - All existing and common functionalities of electric window regulators or the movement sequences of window panes of the side windows of the motor vehicle can be implemented and implemented in a simple manner; in particular, an automatic function (the automatic mode as a movement mode) can also be easily implemented for the operator.

Fig. 1 is a flow chart for controlling the movement sequence of the window panes by continuously rotating a hand crank as an operating element,

Fig. 2 is a flow chart for controlling the movement sequence of the window panes by once moving a hand crank as an operating element in a specific rotational direction.

To implement the electric window lift function of a motor vehicle, an electric drive unit is provided as a window lift drive with a permanently excited direct current motor, a gearbox mounted on the permanently excited direct current motor, cable pulls for moving the window panes and a door control device. The electric window regulators of the motor vehicle are operated via two operating elements arranged in the front of the motor vehicle and designed as a hand crank; the door control unit evaluates the movement and / or position of the crank operated in each case and controls the electric window regulators accordingly. For each operator (ie for the driver and for the front passenger), e.g. Such a hand crank is provided as an operating element, a hand crank on the driver's side of the motor vehicle and a hand crank on the passenger's side of the motor vehicle being integrated in the respective door. The respective hand crank is e.g. intended for operating both electric window regulators on one side of the motor vehicle (the driver's side or the passenger's side); In addition, the hand crank on the driver's side is used to operate the two electric window regulators and thus to control the sequence of movements of the two window panes (the front window and the rear window) on the passenger side of the motor vehicle, so that by operating the hand crank on the driver's side (i.e. depending on the corresponding request by the driver as operator) a control of all electric window regulators and thus a control of the movement sequence of all front windows and all rear windows of the motor vehicle is made possible. The different movement sequences (in particular "manual run-up", "automatic run-up", "manual run-down" and "automatic run-down") of the window panes are selected by selecting the desired window pane by turning the hand crank out of the rest position in accordance with the direction of rotation of the hand crank and / or the rotation speed of the hand crank and / or the position of the hand crank predetermined movement sequence: in a first embodiment according to FIG. 1 by the direction of rotation and the rotation speed of the hand crank during continuous rotation of the hand crank (rotation of the hand crank, for example, by a maximum of four full revolutions possible , by a maximum of 1440 °) and in a second embodiment according to FIG. 2 by the direction of rotation and the (end) position of the hand crank after actuation when turning or moving the hand crank once in a certain direction of rotation (rotation or shifting the Hand crank e.g. by m axially a quarter turn possible, ie by a maximum of 90 °). For the operator, e.g. the forces occurring during the operation of the hand crank (the while turning the hand crank) are simulated, e.g. by an electromechanical control unit; E.g. a direct relationship between the operating speed of the hand crank (in particular the rotational speed of the hand crank) and the speed of the movement of the selected window pane is specified. After actuation of the hand crank is completed (especially when the hand crank is operated by continuous turning), the hand crank is reset to a defined starting position regardless of the current position of the selected window pane, so that the hand crank can be easily reached by the operator for subsequent operations.
