Abstract : The introduction of multiple networking technologies and protocols in automotive, starting from CAN in 1990 to TTP, FlexRay, Ethernet to date has given way to new modelling methodologies which are software based. In today’s automotive, more than 100 ECU’s exchange thousands of events to determine the diagnostics at a given point of time. The quality of the vehicle over time will be a function of these events and new concepts along with solutions in this area will be of great interest to automotive OEM’s. In this paper we will see how these events are correlated. Having this correlation is a great asset to all stakeholders in the automotive industry. We will analyze the concept of event correlation and two different methods to implement event correlation in automobile platform with dedicated ECU for the purpose to be preferred method of implementation.
