Abstract:
A pushbutton device for actuating an electropneumatic parking brake (EPH) of a vehicle, which is connected to an evaluating electronic unit via connecting cables. In order to detect switching processes and/or faults, the input resistance of the pushbutton device between the connecting points is evaluated, thus allowing the evaluating electronic unit to reliably detect both the switched position of the pushbutton device and potential fault conditions.
