Problems solved by technology

However, in this procedure too, fluctuations in the clamping force can only be compensated insufficiently, since changes in the adjustment speed are only partly caused by fluctuations in the on-board voltage, ie the supply voltage.

Embodiment Construction

[0021] in accordance with figure 1 The shown graph shows the (measured) clamping force on the clamped object with a curve 1, wherein the clamping process is assumed to start at time T1. In addition, the speed of the motor is represented by a curve 2 as a measure of the component speed, where it can be clearly seen that the speed of the motor begins to decrease from time T2, which is after time T1, so that finally at time T4, if clamping is detected , generally drops rapidly to zero (because the motor is stopped). Finally, a curve 3 is used to illustrate the motor current, wherein the motor current starts to rise at time T3 due to the clamping process, until finally at time T4 when clamping is detected, when the motor stops, the motor current according to image 3 suddenly drops to zero. However, the time T3 is located after the time T2 at which the speed reduction of the electric motor starts. Also in figure 1 Also plotted in is the relative change in current -ΔI-, and the...

Abstract

For the purpose of detecting a jam during the adjustment of a component of a motor vehicle using an adjustment drive, wherein measured values related to the adjustment force (F) are compared to a threshold value (FREF) and when the threshold value is reached, the adjusting movement is slowed or stopped, and optionally reversed, it is proposed that the component speed or a parameter correlated therewith is detected and the threshold value (FREF) modified accordingly.

Description

technical field [0001] The invention relates to a method for detecting a clamping situation during the adjustment of a motor vehicle component by means of an adjustment drive, wherein measured values ​​relating to the adjustment force are compared with a limit value, when the limit value is reached, the speed of the adjustment movement is reduced Or stop and reverse if necessary. [0002] Furthermore, the invention relates to a device for detecting a clamping situation during the adjustment of a motor vehicle component by means of an adjusting drive, with means for detecting measured values ​​relating to the adjusting force, which are stored in a comparator unit , in order to compare it with a limit value and, if the limit value is exceeded, to adjust the movement to reduce speed or stop, and reverse if necessary. Background technique [0003] When adjusting externally actuated components in motor vehicles, in particular electric window regulators or sliding sunroofs, a cla...
