Abstract

The invention relates to a communication device (10) for automotive communication, comprising a microcontroller (12) for generating a microcontroller output signal (14) and receiving a microcontroller input signal (16. The microcontroller output signal and the microcontroller input signal respectively indicate a voltage (18a, 18b) with respect to a first ground potential (20). Further the, communication device (10) comprises a bus transceiver (22) for generating a bus signal (24) depending on a transceiver input signal (26) which depends on the microcontroller output signal (14) and for observing the bus signal (24) for providing a transceiver output signal (28) depending on the bus signal (24). The transceiver input signal (26) and the transceiver output signal (28) respectively indicate a voltage (30a, 30b) to a second ground potential (32). Moreover the communication device (10) comprises a shifting module (34) for detecting a potential difference (36) between the first ground potential (20) and the second ground potential (32), for shifting a potential (38) of the microcontroller output signal depending on the detected potential difference (36) to output the transceiver input signal (26) and for shifting a potential (40) of the transceiver output signal (28) depending on the detected potential difference (36) to output the microcontroller input signal (16).The invention further relates to a network System (90), a vehicle comprising a communication device (10) and a method (110) for automotive communication in a vehicle.
