ii Networked control systems are being used extensively because of their reliability, cost effectiveness and manageability. The automotive industry uses Controller Area Network (CAN) for exchanging data among multiple Electronic Control Units (ECU). Each ECU has a set of dedicated control tasks such as engine control, transmission control, brake systems management, traction control, etc. Generally, every control task needs information from multiple ECUs and sensors to perform its duties. And CAN helps in minimizing the wiring requirements while maintaining a reliable pathway for data exchange among ECUs. The use of CAN as a part of control loop introduces certain effects on the performance of the control which are significant and non-linear. Therefore it is important to include the CAN behavior in model based control design and simulations. The work presented in this thesis develops a CAN simulator on MATLAB/SimEvents platform that can be integrated into existing vehicle simulators for control systems simulations. The CAN simulator is built for shorter simulation time an
