LIN refers to "Local Interconnect Network", a global standard of serial multiplex communication protocol*1 administrated by LIN consortium. A communication circuit employing the LIN protocol connects each ECU, and switch data can be shared among ECUs, which enables more reduction in wiring. Transmission speed is 19.2 kbps*2.
ETACS*3-ECU can receive some input signals through CAN*4 communication in addition to the LIN communication.
note *1: 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.
note *2: bps (bit per second)
note *3: ETACS (Electronic Time and Alarm Control System)
note *4: CAN (Controller Area Network)
