Design and Development of Fault Tolerant Can-Lin Gateway for In-Vehicle Communication (original) (raw)

In last few decades, the rising numbers of sensors, actuators and ECUs have increased the complexity of automotive network. Moreover, multiple network communication protocols such as CAN, LIN, FlexRay, MOST are used in today’s cars to meet the various requirements of in-vehicle applications. While CAN is the traditional automotive field-bus used in engine management, LIN provides a low-cost network solution for car window and door applications. In many instances data has to be shared between various networks using different protocols. Network gateway(GW) enables this data exchange with optimum utilization of the available data / signals. Typically over 25-45 ECUs connected in a vehicle with two to four different network protocols exchange approximately 100-300 signals and data [1],[2]. An error free data transfer from one protocol to another through GW ECU is a challenging and critical task. Failure or error in data exchange can lead to safety problems or inconvenience to the passen...
