Control unit for current-controlled bus wherein sampling a current flowing through bus connection in order to detect digital message of a connectable sensor
An electronic control unit includes a bus connection for a connection to a bus line of a current-controlled bus, an evaluation device for sampling the current flowing through the bus connection in order to detect a digital message from a sensor which is connectable to the bus line, and a current controller for generating a predefined current pulse through the bus connection in order to induce the sensor to assume a predefined synchronization state. The current controller is set up to control the current through the bus connection in such a way that it corresponds to an operating current through the sensor.
