A foot brake module of an electropneumatic brake system of a motor vehicle has at least two pneumatic brake circuits. The foot brake module is operated by a brake pedal and has a pneumatic section with a pneumatic brake control valve and an electrical section with an electrical switch and at least one electronic travel sensor. The electrical switch is activated in a contactless manner. The foot brake module may have two travel sensors that each have a separate power supply and are connected to different electronic control devices.

A system for transmitting a value via a pulse-width-modulated signal, comprises a transmitter and a receiver. The transmitter is configured for detecting the value and for outputting a pulse-width-modulated signal having a pulse width which represents the value or a range around the value. The receiver is configured for deriving the value or the range from the pulse-width-modulated signal, by evaluating the pulse width. The transmitter is furthermore configured to read back the emitted pulse-width-modulated signal and to check whether the value or the range can be derived from the emitted pulse-width-modulated signal, and, if the value or the range cannot be derived, to output an error signal to the receiver.

Transmission of a value by means of a pulse-width-modulated signal

In a device for sensing the position of a shift fork in a transmission, the shift fork is connected to a piston rod of a shifting piston which is guided axially in a shifting cylinder. The shift fork engages an axially slidable sliding sleeve, which slides on a transmission shaft, to engage or disengage a transmission stage. A magnet functioning as a signal generator is arranged on an actuating element, such as the switching piston, piston rod or shift fork. A 3D Hall sensor positionally fixed relative to the magnet functions as a signal receiver, sensing a magnetic field generated by the magnet. An electronic control unit connected to the 3D hall sensor determines the position of the shift fork from the relative positions of the magnet and 3D Hall sensor and transmits the position as a signal, taking into account linear, rotational, and/or pivoting movements of the actuating element.
