VEHICLE TEST SYSTEM INCLUDING PLURALITY OF APPARATUSES MUTUALLY COMMUNICABLE VIA NETWORK
First Claim
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 system comprising:
- a control apparatus mounted on the vehicle, having a plurality of objects being controlled which executes a series of procedures to perform at least one function and each object has a fault detecting module for detecting fault information about faults occurring at the controlled object;
a first communication means adapted to the control apparatus for communicating with other apparatuses via the network, receiving data sent from the other apparatus of which sending destination is any one of the objects being owned by the control apparatus and sending data concerning the object to the other apparatus;
a test apparatus being electrically connected to the control apparatus via the network;
a fault information reading means adapted to the test apparatus for reading fault information at the object being owned by the control apparatus;
a second communication means adapted to the test apparatus for communicating with any one of the objects being owned by the control apparatus as a communication partner; and
a transmission control means adapted to the control apparatus for transmitting the fault information at the object to the test apparatus based on a sending request command being sent by the fault information reading means;
whereinthe object executes the series of procedure in response to the received data sent from the other apparatus, the fault information reading means is configured to send the sending request command via the second communication means, to any one of the objects to send both the fault information included in the any one of the objects and the fault information included in the other 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 object designated by the sending request command, to the test apparatus when the first communication means receives the sending request command.

Abstract
A test apparatus sends a command to an A-control module as a destination. The command includes a request to send fault information at the A-control module and a B-control module being included in an integrated ECU to the test apparatus. The A-control module reads the own diagnostic code and orders the B-control module to read the diagnostic code of the B-control module. The B-control module reads the own diagnostic code in response to the order from the A-control module. A response data generation module in the A-control module generates a fault information command based on the diagnostic codes detected by the A-control module and the B-control module and sends the command to the test apparatus.

12. A control apparatus connected to a network arranged in a vehicle, mounted on the vehicle, mutually communicable with other apparatuses being connected to the network, the control apparatus comprising:
-
a plurality of objects being controlled which executes series of procedures to perform at least one function, each controlled object has a fault detecting module for detecting fault information about faults occurring at the controlled object; and a communication means for communicating with other apparatus via the network, receiving data sent from the other apparatus of which sending destination is any one of the objects being owned by the control apparatus and sending data concerning the object to the other apparatus;
whereinthe object executes the series of procedure in response to the received data which is sent from the other apparatus;
the communication means is configured to receive a sending request command sent from a test apparatus being connected to the network, the command orders any one of the objects that the control apparatus owns to send the fault information being included in any one of the objects and the fault information being included in the other object that the control apparatus owns; and
the control apparatus further comprises a transmission control means that orders the communication means to transmit the fault information in response to the reception of the sending request command, the fault information being included in the objects that is designated by the sending request command, fault information being detected by the fault detecting module. - View Dependent Claims (13, 14)
