CAN was developed by Bosch in the 1980s and has since become a standard in the automotive industry due to its reliability, robustness, and low cost.CAN is used for communication between different automotive systems, such as the engine management system, transmission control system, chassis control system, and body control system. By using a single communication bus, CAN eliminates the need for multiple wiring harnesses and connectors, reducing weight and cost while improving reliability.CAN protocol has two types of messages: standard and extended. The standard CAN message has an 11-bit identifier, while the extended CAN message has a 29-bit identifier. This allows for a greater number of messages to be transmitted on the CAN bus. CAN also uses a priority-based message arbitration system, which ensures that higher priority messages are transmitted first.In addition to the standard CAN protocol, there are also several application-specific protocols used in the automotive industry. For example, the J1939 protocol is commonly used for heavy-duty vehicles, while the CANopen protocol is used in industrial automation and control systems. The OBD-II protocol is used for onboard diagnostics and emissions monitoring in vehicles.One of the key advantages of CAN protocol in the automotive industry is its ability to diagnose faults and malfunctions in the vehicle's systems. Diagnostic tools can be used to access the CAN bus and retrieve information about the vehicle's systems and components, including diagnostic trouble codes (DTCs) and real-time data.Overall, CAN protocol has become an essential part of modern automotive technology, enabling efficient and reliable communication between different systems in vehicles.
