Nowadays, automotive wire harnesses have become very complex systems as the number of electronic components and Electronic Control Units (ECUs) inside a vehicle have increased dramatically.

Abstract

Nowadays, automotive wire harnesses have become very complex systems as the number of electronic components and Electronic Control Units (ECUs) inside a vehicle have increased dramatically. To manage this complexity, and to support the automotive systems of tomorrow, new communication techniques need to be investigated. In this work, a direct modulated Power-Line Communication (PLC) method is proposed to drastically reduce the number of interconnections and give advantages in cost, complexity, and weight. Two transmitter topologies based on a Switching Capacitor approach are presented and implemented in a Test Chip fabricated in a 180 nm HV-CMOS SOI technology. The proposal is validated by communication tests connecting the designed chip and a discrete component-based demonstrator receiver through an unshielded twisted pair cable. Compared to commercially available solutions, the proposed approach can reach a data rate of 2 Mbps, making it able to implement high-speed event-driven networks, such as the Controller Area Network (CAN).
