Functional safety of hybrid electric and electric vehicles has attracted a great deal of attention among automobile industries worldwide. Torque security is one of the main hazards that should be considered for functional safety of electrified vehicles. Over the past decades, a significant number of accidents have been reported to be caused by unintended acceleration that results from torque security problems. This paper investigates the factors related to torque security problems in electric vehicles using the Failure Modes and Effect Analysis (FMEA) approach. The fault scenarios that can potentially result in loss of torque security in electrified vehicles are evaluated in a simulation study.
