【Abstract】With therapidadvancement of autonomous driving technology，L3 and higher-level intelligent driving functionshave imposed stricter requirementsonthefunctional safetyof vehicle systems.Thispaper explores the functional safetydevelopment process forlow-voltage power supply systems in autonomous vehiclesbased on ISO 26262 standard.By adoptinga V-modeldevelopmentframework，thestudycovers hazardanalysis HARA，functionalsafetyrequirement extraction， systemtopologydesign，failure mode analysisFMEA/FTA，andsoftware/hardware implementationandverification，establishing a comprehensive development architecture.Aredundant power supply architecture is proposed to meet the power demands of advanced autonomous driving systems such as HWP/TJP.This systematic methodology provides a robust approach for ensuring power supply safety in autonomous vehicles，ofering valuable guidance for engineering practices.
