Vehicle Sensors Programming Based On Controller Area Network (CAN) Bus Using Canoe

Controller Area Network (CAN) is a network that allows communication between ECUs in a vehicle by introducing a cheaper and light-weight communication medium. CAN is an asynchronous protocol yet provides efficient synchronous mechanism. Therefore, it is crucial to make sure the message transmission in CAN bus is accurate and does not miss its deadline. Local Interconnect Network (LIN) bus, is widely adopted as an alternative and additive bus protocol that has been used to complement CAN. In this project, the objective is to investigate the performance of the CAN signal generated from CAN simulator - CANOE, with and without the integration LIN. Moreover, this paper aims to observe the difference between these two different methods of signal transmission. As to create an experiment environment with the CAN and LIN simulation, the KWP Diagnostic Tester is created. Based on the established model, 4 cases have been introduced to create 4 different test environments, to showcase the different type of data transmission. It is shown that the CAN has an improved average of 2.7% on the transmission speed compared to CAN+LIN.
