Abstract: The application and importance of vehicle monitoring systems based on the Controller Area network (CAN) Protocol in the contemporary automotive engineering are examined in this research. These systems make use of the CAN Protocol’s dependability and efficiency to allow electronic control units (ECUs) in cars to communicate with one another in real time. They offer thorough monitoring of important characteristics including engine performance, vehicle speed, fuel level by collecting the information from components like sensors. This paper highlights the role that CAN Protocol-based vehicle monitoring systems play in improving vehicle performance, safety, and maintenance efficiency. It also analyzes the design, functioning, diagnostic capabilities, and advantages of such systems.

Keywords: CAN, ECU, Vehicle Monitoring System, Diagnostics capabilities, maintenance efficiency.
