Implementation of a CAN Bus based hybrid control unit in an X in-the-loop-system

Compared to traditional vehicle, the number of electronic control units inside the modern vehicle is much greater. Small electronic control units control the small electronic components, such as lights, dashboards, and windows. There are larger electronic control units, the hybrid control unit, the motor drives, etc. Since the various electronic components exchange messages frequently, the communication protocol is very important. This thesis will introduce the basic architecture the advantages and disadvantages of several common means of communication first, and determine which communication method should be implemented. Second, Controller Area Network (CAN) module’s architecture of the MPC, precautions and setting methods will be discussed. The CAN of the existing micro-controller is tested within the MPC initially, and then the MPC is connected to the vehicle’s power train model within the dSPACE to conduct communications test of the CAN with a simple power distribution method. Analysis of the test results is exercised and the communication is confirmed to be successful.
