This invention discloses a hardware-in-the-loop simulation testing system and method for vehicle controller testing, belonging to the field of automotive simulation testing. It integrates a hierarchical fault simulation device, which is composed of a software-programmable fault injection unit and a physical disconnection intervention unit (BOB box), supporting composite fault simulation of automated software fault injection and manual physical disconnection intervention. The method includes: achieving one-click rapid integration of the Simulink simulation model into the VeriStand platform through specific interface replacement and compilation configuration; using TestStand to orchestrate automated test sequences; and using dedicated plugins to collaboratively control the VeriStand project and the hierarchical fault simulation device to complete the fully automated execution and evaluation of the test process. This invention significantly improves the coverage depth and scenario realism of fault testing, drastically shortening the complex testing cycle from several months to less than 72 hours, achieving safe, efficient, and comprehensive VCU hardware-in-the-loop verification.

The application relates to natural language processing technology and discloses a software fault feedback processing method, which comprises the following steps: performing entity extraction on fault feedback text to obtain first fault entities; performing text recognition on fault feedback images to obtain image text; performing entity extraction on the image text to obtain second fault entities; identifying a fault category corresponding to the fault feedback text; screening all processing method knowledge bases by using the fault category to obtain a target processing method knowledge base; screening processing method text in the target processing method knowledge base by using the first fault entities and the second fault entities to obtain target processing method text; and sending the target processing method text to a preset terminal device. The application also relates to a blockchain technology, and the processing method knowledge base can be deployed in the blockchain. The application further provides a software fault feedback processing device, an electronic device and a readable storage medium. The application can improve the accuracy of software fault feedback processing.
