Since the release of the first production vehicle to feature a CAN-based multiplex wiring system in 1991, in-vehicle networking has reduced cost and vehicle weight with the elimination of complex wiring harnesses, improved efficiency utilizing advanced engine management techniques, and improved the driving experience with a multitude of automation and infotainment capabilities.
One bus cannot fulfill all networking objectives with the industry embracing buses such as: LIN for simple control applications; SENT, where predictability low latency and timing accuracy is key; and more recently, in-vehicle networking (IVN) which has adopted a variant of the Ethernet standard for high data throughput applications such as advanced driver assist (ADAS) and infotainment. All, however, must be low cost and have immunity from external noise, with the ability to operate in harsh environments such as temperature and humidity extremes. Finally, bus traffic must go between different suppliers’ electronic control units (ECUs) that may have different electrical characteristics causing interoperability issues, especially in extreme operational conditions such as temperature.
In this webinar we will discuss both troubleshooting and compliance measurement techniques for in-vehicle networking technology such as CAN, LIN and SENT protocols, including their electrical specifications and theory of operation. In the case of CAN, a simple resistance measurement can give a basic health indication. With the evolution to high-speed Ethernet, we will also explore more advanced interoperability measurements such as clock frequency and jitter with a PAM3-based physical layer.
