Abstract: Basically, the signal delivery and quality of sensor data is of growing importance for modern automotive control applications. The use of analog signaling, which is the actual state of realization in many cases, is sensitive to the time variant effects mentioned before. This time variance is hard to consider for the control system development. In this paper we will analyze the role of the sensor in the signal supply chain and discuss approaches for digital sensor ECU communication and their potential to establish a link. The increasing legal requirements for safety, emission reduction, fuel economy and onboard diagnosis systems push the market for more innovation solutions with rapidly increasing complexity. Hence, the embedded systems that will have to control the automobiles have been developed at such an extent that they are now equivalent in scale and complexity to the most sophisticated avionics systems. This paper will demonstrate the key elements to provide a powerful, scalable and configurable solution that offers a migration pass to evolution and even revolution of automotive sensors and sensor interfaces. The document will explore different architectures and partitioning.
