摘要
PROBLEM TO BE SOLVED: To provide a system and a method for analyzing any abnormality for a vehicle, and a vehicular trouble analyzer capable of specifying a failed part with high accuracy without considerably impairing the transmission of the normal control data from a node to a communication bus.;SOLUTION: There are provided a plurality of nodes for transmitting the control data to a communication bus, and a failure analysis apparatus which receives the control data to be transmitted from each node to the communication bus and estimates the failed part based on the control data. The failure analysis apparatus requests the transmission of the additional data necessary for the analysis of the failed part different from the normal control data to a predetermined object node out of the total nodes when the failed part is estimated, and each node transmits the additional data to the communication bus when the transmission of the additional data is requested from the failure analysis apparatus. The failure analysis apparatus receives the additional data to be transmitted to the communication bus from each node, and specifies the detailed failed part based on the additional data.;COPYRIGHT: (C)2010,JPO&INPIT
