Definitions
- the present invention relates to a motor vehicle window lifter with a drive device.
- Such a motor vehicle window lifter with an electric drive and a traction means, which is coupled on the one hand with the drive and on the other hand with the window pane to be adjusted, and which transmits the adjusting force generated by the drive to the window, is known for example from DE 199 30 541 B4.
- the invention is based on the object of specifying a motor vehicle window lifter, which works reliably, in particular even at temperatures below freezing. This object is solved by the features of the independent claim. Advantageous developments of the invention can be found in the dependent claims.
- the invention is based on the idea of freely shaking a blocked window pane of a motor vehicle window lifter by means of the drive device of the motor vehicle window lifter.
- a motor vehicle window lifter preferably has a drive device, in particular comprising an electric motor, which is already used for lifting and lowering a window pane of a motor vehicle.
- a power transmission device such as a rod, a belt, a belt or a belt
- a control device for example a program-controlled processor device or an application-specific circuit device, for controlling the drive device and / or the power transmission device is set up such that an upward force and a downward force are automatically alternately transmitted to the windowpane when the window pane is in a blocked state.
- an upward force and a downward force are automatically alternately transmitted to the windowpane until the windowpane is no longer in a locked state. Then the window pane can be moved in a direction desired by the driver and / or entered via an actuating element.
- a motor vehicle window lifter in which a blocked state is defined by the force transmitted to the window pane or a variable correlating therewith, such as, for example, the voltage or current supplied to the drive device, exceeds a predetermined threshold value.
- a blocked state is defined by the force transmitted to the window pane or a variable correlating therewith, such as, for example, the voltage or current supplied to the drive device, exceeds a predetermined threshold value.
- a blocked state within the scope of the invention is advantageously defined by the fact that the window pane is in the upper end position. Because the "free shaking" is highly likely to be effective or useful only if the window pane is in the upper end position, so when the window is closed. As a rule, the window is closed when the cause of the blockage lies in a frozen window.
- a blocked state within the scope of the invention is advantageously defined by the fact that the temperature is below a predetermined threshold, for example below 5 degrees Celsius. Because the "free shaking" is highly effective only useful or useful if the window is frozen.
- the window regulator according to the invention can also be implemented in a reduced-conflict manner together with automatic anti-trap protection.
- Detection means may be provided for detecting the blocked state, which may be realized entirely or partially by the control device and / or by separate sensor devices or measuring devices.
- the force transmitted to the windowpane or a variable correlated therewith can be measured by a force, current or voltage measuring device
- the temperature can be measured by an electronic thermometer and / or the upper end position can be measured by a sensor
- a switch and / or a force, current or voltage measuring device are detected.
- the explained conditional (when locked state is present) "free shake" by the driver via the actuation of a corresponding actuating element (window open switch) is triggered.
- the change between the transmission of an upward force and the transmission of a downward force on the window pane is advantageously carried out with a predetermined frequency, for example in the range of the resonant frequency of the window pane (with or without associated components) or based thereon.
- the frequency is varied during a blocked state.
- the variation of the frequency takes place, for example, continuously, quasi-continuously or in discrete steps from an upper frequency limit value to a lower frequency limit value or vice versa.
- the course of the force transmission over time can be, for example, rectangular, triangular, pulsed, pulsed or sinusoidal.
- Between the upper frequency limit and the lower frequency limit is preferably the resonant frequency of the windowpane.
- Figure 1 shows a schematic diagram of an electric window
- Figure 2 shows a simplified flow diagram of a window opening method
- FIG. 3 shows a simplified flow diagram of a deblocking method
- Figure 4 shows the time course of the transmitted to a window pane
- the electric window lifter shown in Figure 1 comprises an actuating element 1, such as a switch through which a driver can activate the window directionally selective to open or close the window.
- actuating element 1 such as a switch through which a driver can activate the window directionally selective to open or close the window.
- an electric motor 3 is driven.
- the force or the torque delivered by the electric motor 3 is transmitted to the window pane 4 via a power transmission device 7.
- the window 4 is moved up or down and thus closed or opened the window.
- an upper or lower end position switch 6.5 it is detected whether the window pane is in the upper or lower end position.
- the upper or lower end position can also be detected by a time characteristic characteristic of the upper or lower end position of the force supplied by the electric motor 3 or of a variable correlating therewith.
- the window is in the closed state.
- the step “trigger electric motor” is triggered, whereupon a force is transmitted down to the window pane by the electric motor via the power transmission device.
- End position reached After the deblocking process, it is checked whether the window has reached the lower end position ("End position reached?"). If the window has reached the lower end position, the process is resumed with the start state, but with the window in the open state. If the window has not reached the lower end position, there is still a blocked state ("Disc blocked”) and the procedure resumes with the startup state, with the window either closed or half open.
- the process is resumed with the start state, but with the window in the open state. If the window has not reached the lower end position, the window is partially open and is optionally further moved by the electric motor.
- n is not equal to nmax, the process continues with the start state, where T equals T and n equals n.
- T T + x
- T is equal to Tmax, it is checked by a prolonged downward force on the window pane whether the windowpane is deblocked ("success rate"). Then, the step "end position reached?" is continued after the step "deblocking" in the method of FIG.
- T is other than Tmax, the process continues with the start state, where T is T and n is n.
- nmax is preferably greater than 2, greater than 5, greater than 10, greater than 50 or greater than 100.
- Tmax is preferably less than 1 second, less than 10 seconds, less than 1 minute or less than 10 minutes.
- FIG. 4 again shows the time profile of the force transmitted to the window pane by the electric motor and / or the power transmission device and the various times tauf, tw1, tw2, tzu and already explained with reference to FIG.
