Abstract:
1. A test system for detecting a fault in control of a vehicle, having a plurality of apparatuses mutually communicable via a network arranged in the vehicle, the apparatuses being mutually communicable based on a communication protocol applied to the network, the system comprising: a plurality of objects each being controlled which executes a series of procedure to perform at least one function thereby controlling the vehicle, at least one of the objects including a fault detecting module that detects fault information about fault occurring at the object in control of the vehicle, the object being assigned with an unique communication ID defined by the communication protocol; a first apparatus comprising a first control unit, mounted on the vehicle, being connected to the network, the first apparatus including two or more objects as a first object among the plurality of the objects assigned to the first control unit to be controlled thereby, and the first apparatus being assigned with an unique communication ID defined by the communication protocol and having entire communication IDs assigned to the two or more objects; a second apparatus comprising a second control unit, mounted on the vehicle, being connected to the network and mutually communicable with the first apparatus via the network, the second apparatus including at least one object as a second object among the plurality of objects assigned to the second control unit to be controlled thereby, and second apparatus being assigned with an unique communication ID defined by the communication protocol; first communication means adapted to the first apparatus for communicating with the second apparatus via the network, receiving data sent from the second apparatus, the data being sent to any one of the two of more objects as the first object determined by the communication ID, included in the first apparatus and sending data concerning the any one of the two of more objects as the first object to the second apparatus; a test apparatus being electrically connected to the first apparatus via the network; fault information reading means adapted to the test apparatus for reading fault information at the first object included in the first apparatus, the fault information reading means sending a sending request command to the first apparatus; a second communication means adapted to the test apparatus for communicating with any one of the two of more objects as the first object included in the first apparatus; and transmission control means adapted to the first apparatus for transmitting the fault information at the first object included in the first apparatus, to the test apparatus in response to the sending request command, the transmission control means generating a response command indicative of the fault information detected by the fault detecting module and to order the first communication means to transmit the response command to the test apparatus, wherein the first object executes the series of procedure in response to the data received by the first communication means which is sent from the second apparatus, the fault information reading means is configured to send the sending request command via the second communication means, to any one of the two of more objects as the first object to send both the fault information included in the any one of the two of more objects as the first object and the fault information included in an object other than the any one of the two of more objects as the first object; and the transmission control means is configured to order the first communication means to transmit the fault information detected by the fault detecting module being included in the any one of the two of more objects as the first object designated by the sending request command, to the test apparatus when the first communication means receives the sending request command.
