Description

[0026] In the following, the disclosure is described by means of an exemplary embodiment, which is explained in more detail by means of an illustration, wherein:

[0027] FIG. 1 shows a flow chart of a method for configuring a jamming detection system according to the embodiment.

[0028] In the following description, the same reference numerals are used for comparisons and parts having the same effect.

[0029] In particular, it should be noted that the individual parameters or the individual correlation variables defining the relationships between forces on a cover of the adjusting device and measured motor variables or motor parameters are determined for each specimen of a motor vehicle, for example, during the final test after assembly of the adjusting device or the electric motor of the adjusting device, and are stored in the motor controller. In particular, motor parameters such as the motor constant and the armature resistance are determined from characteristic curve measurements. Suitable parameters from measurements in the roof system or the adjusting device are also measured on the EOL test stand. The transmission factor from clamping force to force on the electric motor can be determined, for example, from clamping force measurements on the EOL test stand.

[0030] In this way, the clamping force and the reversing distance can be narrowed down in the algorithms used, taking into account the actual parameters of the electric motor and the jamming detection system. This leads to a higher precision of the jamming protection and thus to a reduced scatter of the clamping force. The extraction of the individual correlation variables is also largely cost-neutral, as this is done from tests already required elsewhere.

[0031] FIG. 1 shows as an example an embodiment of the method according to the disclosure for the configuration of a jamming detection system having an adjusting device comprising an electric motor for closing at least one opening in a vehicle such as a sliding roof and/or a window, in particular a side window. Thus, in a first step 1, the clamping force and the resulting motor reaction are measured. In a second step 2 the measured clamping force and the measured resulting motor reaction are read out. In a third step 3, individual correlation variables are calculated and stored. These calculated individual correlation variables can be stored, for example, in a motor controller of the adjusting device. Not shown is the step following step 3 of using the calculated individual correlation variables to configure the jamming detection. Instead, an optional fourth step, in which the jamming behavior is changed, is shown in the embodiment of FIG. 1. In this way, the desired setting force can be set according to the individual correlation variables.
