Method for controlling function of parking brake of motor car, involves generating rectangular switching position signal that has preset value based on switching position in frequency, duty factor, amplitude and/or dynamic amplitude

摘要

The method involves transmitting signals for evaluation by a control switch (1) over a signal line (7), where the signals specify switching positions of the control switch. A function unit is controlled by a control unit (2) based on the switching positions of the control switch. A rectangular switching position signal is generated as the signal specifying the switching position, where the switching position signal has a preset value based on the switching position of the switch in frequency (f), duty factor (DC), amplitude (A) and/or dynamic amplitude (fa). An independent claim is also included for a control switch for controlling a function of a function unit of a vehicle.
