Reduce the overall cost of the vehicle and at the same time introduce innovative features to meet the growing costumer demand is one of the challenges noticed on most automotive companies. Due to the falling price of electronics, multimedia and audio features are becoming popular even on A and B entry vehicles. The introduction of multiplex techniques to reduce wiring content is becoming unavoidable and automotive standards like Local Interconnect Network (LIN) and Controller Area Network (CAN) will eventually be introduced on emerging market vehicles. Besides the cost reduction factor, electromagnetic interference (EMI) constraints rises and must be considered during the design of the electrical / electronic architecture (EEA). One of the most common failure mode observed on network systems regarding EMI is the effect known as crosstalk. The crosstalk phenomenon is the undesirable coupling of energy of one line to another, and causes degradation on the data network. Impedance matching network, grounding topology, harness routing and design, network physical layer and bandwidth are factors that strongly influence the performance of the data network. This paper details a time and frequency domain study of crosstalk aspect on CAN and LIN automotive networks. Numerical simulations of circuitry and network physical layer are shown and a guideline to designing harness systems intending to minimize this effect is presented.
