IN-VEHICLE NETWORK SYSTEM AND METHOD FOR DIAGNOSING THE SAME

摘要

The present invention relates to a vehicle network system which can efficiently diagnose a failure area in a network system for a vehicle and a method for diagnosing the same. According to an embodiment of the present invention, a failure diagnosing method of a controller constituting the network of a vehicle which includes at least one joint connector connecting a plurality of controllers to a main wire via wiring, comprises: a step of detecting a failure regarding at least one different controller; a step of determining the joint connector having in common the plurality of controllers which are detected to be in failure by referring a table in accordance with a structure of the vehicle network system; and a step of storing a failure code which respectively corresponds to the controllers which are detected to be in failure and a failure code corresponding to the joint connector in accordance with the determination result.
