The thesis report presents a technical comparison of four different methods for sensor communication in vehicles. Local Interconnect Network (LIN), Peripheral Sensor Interface (PSI5), Analog Current Loop (ACL) and Pulse Width Modulation (PWM) have been investigated. The focus of the study is EMC characteristics, where radiated emission and susceptibility are investigated in a laboratory setup. Included in the thesis are implementation and documentation of a functional physical test system, much suitable for further investigation of the four studied communication methods as well as rapid implementation of other methods. The results indicate substantial differences between LIN, PSI5, ACL and PWM both in terms of basic functionality and electromagnetic behavior. Of special interest are indications that communication circuitry might possibly be a bigger problem than the actual communication.
