Hardware-in-the-Loop Fault Injection for Traction Control System

This paper presents a multiprocessor hardware-in-the-loop (HIL) fault injection strategy for real-time simulation of faults in traction control system (TCS). TCS models are solved for the implementation in CPU and field-programmable gate array. A timing optimization method based on static timing analysis is proposed to deal with timing error induced by real-time fault injection. A multiprocessor-based HIL platform is constructed, and the pipeline of fault injection unit is designed for the proposed platform. The HIL experimental results validate the effectiveness and applicability of the proposed strategy.
