The Local Interconnect Network (LIN) was developed as a complementally bus standard to the Controller Area Network (CAN bus) to address the need for a cost-efficient network for lower performance devices within the vehicle. While the CAN network was already in place within vehicles, its high bandwidth and advanced error detection capabilities were overkill (and thus, cost-prohibitive) for lower performance applications such as seat and window controllers.
CAN FD is an extension to the Classic CAN protocol that was developed to meet the needs of modern vehicles wherever-increasing numbers of embedded electronics are transmitting ever-increasing amounts of control and diagnostic data. Because the original CAN specification has a maximum bandwidth limitation of 1 Mbps, data-dense activities like ECU flashing and advanced driver assistance systems (ADAS) ADAS applications were being impeded, forcing automotive manufacturers to add multiple CAN networks into newer vehicles.
Communication between these subsystems is critical to ensure the reliability and safety demanded in the automotive market. The Controller Area Network (CAN bus) is a message-based communication network standard that allows ECUs to communicate within a vehicle without the use of dedicated analog signal wires.
