The signal conversion testing controller being connected with the host computer generates corresponding institute according to the fault test use-case Fault simulation signal and the vehicle operating parameters are stated, and is sent to the central controller;
Correspondingly, the central controller generates corresponding failure according to the fault simulation signal and the vehicle operating parameters Control instruction is simultaneously sent to the semi-hardware type simulation test system, specifically:
The central controller generates the corresponding failure control according to the fault simulation signal and the vehicle operating parameters System instructs and is sent to the real-time simulator;
Correspondingly, the semi-hardware type simulation test system is instructed according to the Fault Control carries out vehicle main circuit malfunction mould Intend and run, exports and save fault simulation test result, specifically:
The real-time simulator instructs progress vehicle main circuit malfunction to simulate and runs according to the Fault Control, will obtain Fault simulation result be sent to the host computer;
The fault simulation result is compared by the host computer with the expected results of the fault test use-case, is exported and is protected Deposit the fault simulation test result.
