Abstract

A method for providing a black box service for vehicle diagnosis and an apparatus and a system therefor are disclosed herein. A method for providing a black box service for vehicle diagnosis in an in-vehicle apparatus connected to a network includes confirming whether or not a time synchronization message including a black box address is received, updating status information in the apparatus, when the time synchronization message is received as a result of confirmation, and transmitting a status information message including the updated status information to the black box address set as a destination address. Therefore, a more stable black box service for vehicle diagnosis is provided.

Description

technical field [0001] The invention relates to a black box for vehicle diagnosis, and more particularly, relates to a method and equipment for providing black box service for vehicle diagnosis by utilizing time synchronization messages in the vehicle. Background technique [0002] Recently released vehicles are equipped with various electronic control devices to improve driver convenience and safety. In addition, many such vehicles are equipped with an in-vehicle communication network for intercommunication between these electronic control devices. [0003] In particular, Ethernet is widely used as an in-vehicle communication network. An Ethernet generally includes a plurality of local area networks (LAN: local area network) and a plurality of bridges for connection between LANs. A feature of Ethernet is that a plurality of nodes competitively try to access a shared medium using a Carrier Sense Multiple Access / Collision Detection (CSMA / CD: Carrier Sense Multiple Access / Co...
