Controller Area Network is a high level communication with good stability and reliability protocol. CAN is invented by ROBERT BOSCH. It is used to analysing and controlling the various digital data inside an automobile industry. CAN protocol mainly preferred for vehicle communication. This project is implementing to monitoring and controlling the vehicle communication with the controller of ATMEGA. It is used to monitoring and controlling the engine control unit (ECU), Antilock breaking system (ABS), and also temperature measuring, CO2 is measuring. The simulation of the project has been implemented using MATLAB with the help of Embedded C.
