GENERAL INFORMATION

M1548310000579

CAN, an abbreviation for Controller Area Network, is 
an ISO-certified international standard for a serial 
multiplex communication protocol

*

. A communication 

circuit employing the CAN protocol connects each 
ECU, and sensor data can be shared among, which 
enables more reduction in wiring.
NOTE: 

*

: The regulations have been decided in 

detail, from software matters such as the necessary 
transmission rate for communication, the system, 
data format, and communication timing control 
method to hardware matters such as the harness 
type and length and the resistance values.

CAN offers the following advantages.

• Transmission rates are much faster than those in 

conventional communication (up to 1 Mbps), 
allowing much more data to be sent.

• It is exceptionally immune to noise, and the data 

obtained from each error detection device is more 
reliable.

• Each ECU connected via the CAN communicates 

independently, therefore if the ECU enters dam-
aged mode, communications can be continued in 
some cases.
