Torque security is an important element for future automobile development such as for electric and and hybrid electric vehicles (EV/HEVs). For Drive-by-Wire systems that are commonly used in modern vehicles, pedal position signals are critical for ensuring correct calculation of torque request to the rest of the powertrain. This paper develops a model based fault diagnostic scheme for electrified vehicle powertrain torque security problems, with special focus on pedal position sensor faults. After the design of the diagnostic strategy, a fault tolerant control strategy is proposed to mitigate the effect of the faults. The torque security study is applied to a case study of a prototype vehicle developed by the OSU EcoCAR2 team. The diagnostic and fault tolerant control scheme are tested and validated through Model-in-the-Loop (MIL) and Hardware-in-the-Loop (HIL) simulations.
