Road Vehicles – Controller Area Network (CAN) – Part 3:
Low-Speed, Fault-Tolerant, Medium-Dependent Interface
1 Scope
This Document specifies the interaction characteristics of digital information between CAN- based electronic control units of road vehicles, the fault-tolerant behavior of the low-speed CAN application layer, and the media-dependent interface and physical-media-attachment physical layer based on the ISO/OSI layer model.
This Document applies to CAN serial communication protocol with transmission rate between 40kbps~125kbps, supporting distributed control and multiplexing.
2 Normative References
This Document has no normative References.
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply. 3.1 Bus
Topology of a communication network where all nodes are reached by passive links which allow transmission in both directions.
3.2 Bus failure
Failures caused by a malfunction of the physical bus such as interruption, short circuits. 3.3 Bus value
One of two complementary logical values: dominant or recessive.
NOTE: The dominant value represents a logical “0” the recessive represents a logical “1”. During simultaneous transmission of dominant and recessive bits, the resulting bus value will be dominant. 3.4 Bus voltage
