    • A device and a method for bidirectional single-wire data transmission of data information between an electronic control unit and at least one peripheral unit. A predefined constant voltage and/or a predefined constant current is applied to a driver device of the electronic control unit to produce voltage-coded and/or current-coded information. The voltage-coded and/or current-coded information is transmitted from the driver device of the electronic control unit to a driver device 30 of the peripheral unit via a single-wire line. At least the driver logic of the driver device and/or the communication logic of the peripheral unit are triggered and powered through the current flow. Information occurring on the peripheral unit is current-coded and/or voltage coded due to the triggering thereof. The current-coded and/or voltage-coded information are uploaded from the driver device of the peripheral unit to the driver device of the electronic control unit during the triggering of the peripheral unit via the same single-wire line.
    • 一种用于在电子控制单元和至少一个外围单元之间的数据信息的双向单线数据传输的装置和方法。 将预定义的恒定电压和/或预定义的恒定电流施加到电子控制单元的驱动器装置以产生电压编码和/或电流编码信息。 电压编码和/或电流编码信息经由单线线路从电子控制单元的驱动器装置发送到外围单元的驱动器装置30。 至少驱动器装置的驱动器逻辑和/或外围单元的通信逻辑被触发并通过电流进行供电。 在外围单元上发生的信息由于其触发而被电流编码和/或电压编码。 在通过相同的单线线路触发外围单元期间,将电流编码和/或电压编码信息从外围单元的驱动器装置上传到电子控制单元的驱动器装置。
