Outline
Lateral stability is very important for driving of Electric Vehicles (EV). In order to reduce the risk of oversteering and understeering instability of 4WD EV, based on ISO 26262, the hazard analysis and risk assessment of the lateral stability control function of centralized 4WD EVs were carried out, and the safety goals of the lateral stability control function were determined. The co-simulation analysis of CarSim and MATLAB/Simulink was conducted, which proved that the stability control functional safety requirements are satisfied by safety goals determined. The research results show that the stability control functional safety level of 4WD EVs should be developed according to ASIL D, which can avoid hazards of understeering and oversteering for 4WD EVs, the research results can support the design of lateral stability control function and safety mechanism for 4WD EVs.
