Communication and Control Systems

It is in this module that the student learns the principles of gateways and communication buses. The five main communication protocols in EVs are also described including the CAN protocol.  Communication conductors are also discussed and the basic operating principles of MCUs, VCUs and ECUs are explained.  In addition, an introduction to zonal architecture and domain architecture is presented.
