【Abstract】As the electrificationand intelligence of vehicles accelerate，electric power steering（EPS）systems， as thecoreactuatorforvehicle handling safetyand driving experience，have becomea key technological area in new energy intellgentvehicles.Traditional mechanical hydraulicsteeringsystemssufferfromhighenergyconsumptionand delayed dynamicresponse.Current EPS systems face challenges such asnonlinear fluctuations inasstcharacteristics undercomplexoperatingconditions，multi-physics fieldcoupling interference，andupgraded functionalsafetyrequirements. The corecontradictionisreflected in thebalance between motorcontrolaccuracyand systemlong-termreliability.This papersystematicallyinvestigateskeytechnical issesrelatedtomotorcontrolandreliabilityassuranceinautomotive electric stering systems，aiming to provide theoretical support and practical models for the optimization andupgradeof intelligent electric vehicle safety architectures.
