| 摘要 |
The invention relates to a communication device comprising two electronic control units that each comprise a first electric terminal, a second electric terminal, and a communication terminal connected to the communication terminal of the other electronic control unit by a communication wire, and in which the first electronic control unit has reference voltages (VSUPP, VGND) on its first and second electric terminals and comprises development means suitable for emitting a voltage signal (SLIN) referenced to said reference voltages on its communication terminal, and the second electronic control unit comprises means for processing said voltage signal received on its communication terminal via said communication wire. According to the invention, the communication device comprises two reference wires connecting said first electric terminals to each other, and which also forces said reference wires to travel, with said communication wire, between said two electronic control units. |
