Research on Risk Assessment of Vehicle Failsafe

Traffic accidents caused by operating passenger cars have brought huge losses to society. With the rapid growth of my country's road transport passenger volume, it is essential to improve road safety. The failure of the braking system is one of the important factors leading to traffic accidents in operating passenger cars. This study first summarizes the main types of failures of the passenger car braking system, and then discusses the causes. A risk assessment method of brake system failure factors based on the hierarchy-fuzzy synthesis method is proposed. The classification and risk score calculation of brake system failures of different severity are carried out. Finally, combined with the maintenance records of operating vehicles, a comparison and summary of the occurrence of failures are made. The research results can provide a theoretical basis for the prevention of accidents due to vehicle breakdowns. It is of great significance to improve the level of road safety in our country and ensure the safety of vehicles.
