METHOD FOR PROTECTING AGAINST JAMMING AND JAMMING PROTECTION DEVICE

摘要

The invention relates to a hydraulic actuation device, a method for actuating a clasp or a cover of a cabriolet, a jamming protection device, in addition to a method for protecting against jamming for convertible hoods. A volume flow is guided from a pressure means source to a hydraulic actuation element in order to open the hood. A variable (60, 61) is determined for the hydraulic actuation element, whereby the difference thereof in relation to a desired value (59) is determined. Said difference value (?p₁, ?p₂) is compared to a first threshold value and reduces when the first threshold value is exceeded according to the difference value of the supplied volume flow.
