Based on the research on the safety issues of fuel cell bus power system integration in a certain project,a vehicle fault classification and handling strategy has been developed.On this basis,a safety management approach for fuel cell systems based on the vehicle fault handling process has been proposed,which helps to develop and improve the functionality of the vehicle control system.Subsequently,the structural optimization of the fuel cell vehicle and the layout design of the powertrain were completed,with a focus on hydrogen safety and structural strength.The modeling and simulation of the middle side collision and rear tail collision processes were conducted,and the analysis showed that the structural strength can ensure that key system components are not damaged.The measures taken in this article for integrated safety management and layout design of fuel cell power systems help to improve the functional and structural safety of fuel cell bus systems,and ensure the safe use of vehicles.
