Abstract
A window lifter system comprises a first window lifter motor and a master control device for the first window lifter motor. The master control device is able to detect a position of a window pane driven by the first window lifter motor and to drive the first window lifter motor at a variable speed. The system further comprises at least one second window lifter motor and a slave control device for the second window lifter motor. The slave control device is able to detect a position of a window pane driven by the second window lifter motor and to drive the second window lifter motor at a variable speed. A bus system is provided by means of which the master and slave control devices are able to communicate with each other. There is also proposed a method of controlling such a window lifter system.
