Based on the standard requirements of ISO 26262 Road Vehicles-Functional Safety,this study analyzes the multiaxle electro-hydraulic steering system of special vehicles to enhance the system's safety and reliability.In this study,the Simulation X software was used to establish a detailed simulation model for the multiaxle special vehicle,and simulation experiments were conducted via fault injection.The simulation results and data were analyzed to assess the severity,exposure and controllability of the faults,thereby determining the corresponding automotive safety integrity level.Thus,based on fault injection simulation,the automotive functional safety analysis method can serve as a crucial means to assess architectural safety in the early stages of system design.
