차내망 통신 기술
LIN (Local Interconnect Network)차내의 저비용, 직렬 통신 시스템
최대 속도 20Kbps (EMI-이유로 제한)
간단하고 속도가 중요하지 않은 Application에 이용
CAN (Controller Area Network)고속[최대 1 Mbps),신뢰성을 요하는 전자․제어 장치 간 네트워크
단순한 인터페이스와 값싼 전송매체, Twisted wire pair (EMI 영향을 없음)
차량에서 많은 제어 장치들 (MCU, Sensor, Actuator) 간의 데이터 교환
FlexRay효율적인 빠른 데이터 전송 속도를 위한 네트워킹
TDMA(Time Division Multiple Access) 전송 방식
MOST(Multimedia Oriented System Transport)대용량의 멀티미디어 정보를 전달 (최대 25 Mbps)
광섬유 케이블 이용, 복잡한 인터페이스 및 고비용이 단점
