Title:
METHOD FOR OPERATING A CLOSING DEVICE OF A MOTOR VEHICLE AND A CLOSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/003816
Kind Code:
A3
Abstract:
The invention relates to a method for operating a closing device (1) in a motor vehicle for detecting a pinching case, wherein an object is pinched between a moving closing element (2) of the closing device and a stop edge (3) of the closing device (1) during a closing operation, having the following steps: determining (S2) an indicator of the instantaneous closing force during a closing operation; determining (S4) an indicator of a force of acceleration indicating a force of acceleration acting on the closing element (2) of the closing device (1) during a closing operation; providing (S5) a closing force threshold value depending on the indicator of the force of acceleration; detecting (S6) a pinch case if the determined indicator of the instantaneous closing force exceeds the closing force threshold value.
