Active safety system for Ethernet-based Automobile using Fault-tolerant Ethernet

摘要

The present invention relates to an active safety system for Ethernet-based vehicle through duplexing of backbone switch. The present invention includes a port A (10) and port B (20) which supply a duplexing path; a port C (30) which controls network flow; a fault detector (40) which detects the fault of a network; and a switching chip (50) which controls the network flow. According to the present invention, the present invention duplexes the Ethernet backbone switch that is installed in the front and rear of a vehicle so as to transfer a main signal of the vehicle such as a control signal even if one line of a network is out of order. Moreover, the present invention has an effect of expanding general usage and reducing development time due to low costs by use of a general-purpose element, and being applicable to various environments through a situationally appropriate design change of the fault detector.
