Be used for target detection verification platform (7) and receive test node Tester(1) the message object CRO that issues, to test node Tester(1) reply message object DTO message, with test node Tester(1) set up and demarcate the step that is connected;
Be used for test node Tester(1) call CCP protocol service storehouse (2), the information on services traversal with listing in the CCP protocol service storehouse (2) of circulation sends to the step that measured target is demarcated driver module (5);
Be used for target detection verification platform (7) and receive test node Tester(1) the message object CRO that issues, corresponding step of demarcating service is provided;
Be used for test node Tester(1) measured target that receives is demarcated the step that information that driver module (5) returns and calibrating parameters template compare;
Be used for test node Tester(1) comparison information is processed, show the step of measured target demarcation driver module (5) test result.
5. a kind of automotive electronics calibration software driver module method of testing according to claim 4 is characterized in that, described method of testing also comprises:
Be used for test node Tester(1) step from Object Descriptor table DAQ-ODT tabulation configuration information to target detection verification platform (7) that Object Descriptor table DAQ-ODT tabulation is set and sends;
Be used for target detection verification platform (7) and receive test node Tester(1) the Object Descriptor table DAQ-ODT tabulation configuration information that sends, and according to the Object Descriptor table DAQ-ODT tabulation configuration information that receives, the step that tabulation arranges to Object Descriptor table DAQ-ODT;
Be used for target detection verification platform (7) and fill the step of DAQ-ODT tabulation according to the simulated calibration target data in Object Descriptor table DAQ-ODT tabulation configuration information and the structure data field;
Be used for target detection verification platform (7) to test node Tester(1) upload the step of DAQ-ODT tabulation;
Be used for test node Tester(1) step of receiving target test and verification platform (7) the DAQ-ODT tabulation of uploading.
