ISO 11898-1 is the first part of the standardization that provides guidelines Controller Area Network (CAN) data link layer and high-speed physical layer.
ISO 11898-1 includes Logical Link Control (LLC) sub-layer, medium access control (MAC) sub-layer, and physical signalling sub-layer (PHS).
CAN is a serial communication protocol, that supports distributed real-time control and multiplexing for use within the road vehicles and other control applications.
ISO 11898-1 contains the specification of the following:
ISO 11898-1 on Data Link Layer and Physical Signalling is useful for:
The data link layer and physical signaling helps manufacturers to save money by reduced wiring, time saving with simple wiring , Automatic retransmission of lost messages, Support Error Detection
ISO 11898-1 guideline help to improve safety, by outlining topics on collecting data, fleet management, reducing fuel costs, predicting and avoiding breakdowns in cars, trucks, tractors, buses, etc. Thus, the manufacturers can create a high-tech vehicle and keep track of its components. ISO 11898-1 guideline helps to enable communication among the ECUs..
ISO 11898-1 guidelines can benefit from serial communication to support real-time control multiplexing for use in vehicles, and control applications. The CAN link will help them to understand when the car shows any problems.
