Abstract (en)

[origin: WO2005015816A1] The invention relates to a device and a method for the bi-directional single-wire data transmission of data information between an electronic control unit (2) and at least one peripheral appliance (3), said method comprising the following steps: a pre-defined constant voltage or a pre-defined constant current is applied to a driver device (20) of the electronic control unit (2) in order to produce voltage-coded or current-coded information; the voltage-coded or current-coded information is transmitted from the driver device (20) of the electronic control unit (2) to a driver device (30) of the peripheral appliance (3) via a single-wire line (4); at least the driver logic of the driver device (30) and/or the communication logic of the peripheral appliance (3) is controlled and supplied by the current flow; information resulting from the activation of the peripheral appliance (3) is current-coded or voltage-coded; and the current-coded or voltage-coded information is redirected from the driver device (30) of the peripheral appliance (3) to the driver device (20) of the electronic control unit (2) during the activation of the peripheral appliance (3) via the same single-wire line (4).
