Automotive Engine Wiring Harness Communication Standards

Automotive Engine Wiring Harness communication standards mainly include two protocols: CAN (Controller Area Network) and LIN (Local Interconnect Network).

Performance	LIN	CAN
Medium Access Control	Single Master	Multiple Master
Typical Bus Speed	2.4 to 19.6 kbd	62.5 to 500 kbd
Multicast Message Routing	6-bit ldentifier	11/29-bit ldentifier
Typical Number of Nodes	2 to 10 Nodes	4 to 20 Nodes
Encoding	NRZ 8N1 (USART)	NRZ with Bit Stuffing
Data Byte per Frame	2,4,8 Byte	0 to 8 Byte
Transmission Time for 4 Data Bytes	3.5 ms at 20 kbd	0.8 ms at 125 kbd
Error Detection	8-bit Checksum	15-bit CRC
Physical Layer	Single Wire, Vbat	Twisted Pair, 5V
Clock Generation	Master:Crystal,Slaves:RC/Resonator	Crystal
Relative Cost per Node	0.5	1

CAN and LIN are suitable for different scenarios in engine compartment wiring harness communication. CAN is used for high-speed, high-reliability key engine control systems, while LIN is used for auxiliary systems of modules with low real-time requirements, such as body control (such as windows and wipers).
