  • Publication number: 20220141059
    Abstract: 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.

  • Publication number: 20200248794
    Abstract: 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.

  • Publication number: 20190390765
    Abstract: A device (1) for detecting operating states in a transmission has position sensors (4) for detecting the respective position of shiftable gear elements (6) and has a detector (10) for measuring the temperature in the transmission housing (2). In order to obtain sufficiently reliable and precise information about the temperature in the transmission housing (2), temperatures are measured at locations which are as different as possible in the transmission housing (2). For this purpose there is provision that at least one position sensor (4) has a sensor housing (3), in or at which a detector (10) for measuring the temperature is structurally integrated. In order to determine the temperature at different locations in the transmission housing (2), at least two such combined sensors (4) are used.
