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 via 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 are 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. We will also discuss the future, as it relates to the evolution of Automotive Standards.
