개시된 차량용 이더넷 스위치의 제어 방법은, 진단기의 커넥터와 제1 포트의 연결을 검출하는 단계; VLAN(Virtual Local Area Network) ID 테이블을 참조하여 상기 진단기와 제어부 간 연결을 설정하는 단계; 상기 VLAN ID 테이블을 참조하여 상기 제어부와 차량 내 ECU(Electronic Control Unit) 간의 연결을 설정하는 단계; 상기 진단기와 상기 제어부 간, 인증서 기반 보안 접근(Certificate based Secure Access) 절차를 수행하는 단계; 및 이더넷 스위치의 모드를 잠금 모드로부터 잠금 해제 모드로 전환하고, 상기 VLAN ID 테이블을 참조하여 상기 진단기와 상기 차량 내 ECU 간의 연결을 설정하는 단계;를 포함할 수 있다.

    An Ethernet switch for a vehicle, a method of controlling the Ethernet switch are provided. The method includes detecting a first connection between a connector of the diagnostic device and a first port of the Ethernet switch and establishing a second connection with the diagnostic device by referring to a virtual local area network identifier (VLAN ID) table. A third connection is established between the controller and an electronic control unit (ECU) of the vehicle by referring to the VLAN ID table. A certificate-based secure access procedure is performed between the diagnostic device and the controller. A mode of the Ethernet switch is switched from a lock mode to an unlock mode and a fourth connection is established between the diagnostic device and the ECU by referring to the VLAN ID table.
