Abstract
The invention relates to a method for synchronizing sensors in a sensor array, including at least one electronic control unit and at least one sensor, which are connected to each other by a first and a second line, wherein the sensor is supplied with electric power by the first and second lines, and additionally at least one data signal (a) is transmitted by the first and second lines from the sensor to the electronic control unit, wherein the electronic control unit transmits a defined supply voltage signal having varying polarity as a synchronization signal (b, c) to the sensor, whereupon the sensor transmits at least one data signal (a) to the electronic control unit, after the polarity of the synchronization signal has been reversed.
