Abstract
A method for operating a sensor arrangement in a motor vehicle on the basis of a DSI protocol is disclosed. The sensor arrangement has a central unit as a master and a plurality of sensor units, each having a receiver as slaves controlled by the master. The central unit and the sensor units are connected to a bus line and via the bus cable a communication takes place between the central unit and the sensor units. The method includes selecting a first group of sensor units by the central unit for a first measurement, assigning a first time slot or first time slots within a first cycle respectively to one of the sensor units from the first group by means of the central unit, and broadcasting corresponding first time slot information from the central unit to the sensor units.
