Window regulator system is becoming a complicated mechatronic system. To obtain and improve understandings of system behaviors, this work developed models and simulations. To realize the target, system simulation with uniformed modeling language, VHDL-AMS, is chosen as tool. At first, dynamic behavior of window regulator system is studied with method of averaging by a highly abstracted model. As next, main components, e. g. electrical drive, lifting mechanism, door frame and electronic system, are studied and modelled. Parametrization achieves with information from suppliers, existing data bank and measurements. Component models are verified and validated against their measurements. Afterwards, system simulation is built up by assembling component models. As verification and validation, system simulations are compared to measurements. As applications, simulations are used to investigate anti-pinch processes, influence of drum diameter and so on. Depending on the purpose of usage, they can be further improved. As summary, simulation provides support in development of window regulator systems.
