Abstract (en)
[origin: WO2019238395A1] The invention relates to a method for operating a sensor assembly (2) in a motor vehicle (1) on the basis of a DSI protocol, wherein - the sensor assembly (2) has a central unit (3) as a master and a plurality of sensor units (S1, S2, S3) as slaves controlled by the master, - the central unit (3) and the senor units (S1, S2, S3) are connected to a bus line (4) and - communication between the central unit (3) and the sensor units (S1, S2, S3) occurs via the bus line (4), characterized by the following method steps: - transmitting a first message from the central unit (3) to a first sensor (S1) and subsequently - transmitting a second message from the central unit (3) to a second sensor (S2) without the central unit (3) waiting to receive a reply message from the first sensor (S1). In this way, such a method for operating a sensor assembly (2) in a motor vehicle (1) is provided, in which communication between the master and the slaves can occur regularly with a high payload rate while a predefined ASIL is ensured.
