Abstract: In order to configure the downshift method, and to create signals for an automobile automatic transmission more conveniently, a tilting device of a multi-function device with at least one moveable magnet element as a downshift sensor device is used. When a pedal element causes actuation of a magnet element, a downshift characteristic curve (KL3) is generated with a curve-shaped increase and a maximum followed by a curve decrease (KLS) that ends in a stop window (60). A downshift point (KP) is determined using a tolerance window (59) with a path width, which corresponds to a downshift signal (KS) on a characteristic motion curve (AS) of a motion sensor element.
