Abstract: A method for operating a communications network that includes a computing system, at least one intermediate control unit, and at least one execution unit for each intermediate control unit. The at least one intermediate control unit is communicatively connected to the computing system using a first communication system. Each of the at least one execution unit is communicatively connected to the associated intermediate control unit using a second communication system, which is a master-slave communication system, and used as a slave. A message configuration table for each second communication system is stored in the computing system, the message configuration table indicating a temporal sequence of data to be transmitted on the second communication system in question. For a communication with one of the execution units, data are sent from the computing system, via the associated intermediate control unit, to the execution unit according to the associated message configuration table.

Abstract: The invention relates to a method for actuating closing part systems with actuators (8) in motor vehicles. The actuators (8) in motor vehicles can be electrically or hydraulically operable drive mechanisms. The closing part components are optionally monitored by means of pinch prevention detectors (10) and adapters (17), which take external disturbance variables (2, 3) into account. In the case of controllers (27) of closing part systems, a vehicle inclination signal N&agr; (24), upon ascertainment of the controlling variable (5) Y(t), and in the case of regulators (20) a reference signal Xr(t) (15), is switched to a pinch prevention detector (10) downstream of them, which reference signal is modified by the vehicle inclination signal (27).
