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.
