Analysis Of Smart Vehicle Safety Driving Evaluation And Control Strategy Based On Type-? Fuzzy Theory

With the development of science and technology,smart cars have become a hot spot in contemporary science and technology.Smart cars not only can liberate human hands and brains,reduce traffic accidents to a certain extent,and ease traffic congestion,but also have certain potential safety hazards.Therefore,it is of great significance to conduct a comprehensive and comprehensive assessment of the safety driving risks for smart cars,and to formulate management and control strategies for safe driving of smart cars based on the assessment results.Firstly,a secondary evaluation system has established for the safe driving of smart cars based on four major related technical aspects:perception technology,decision-making technology,control execution and driving assistance systems.Secondly,the fuzzy analytic hierarchy process is used to calculate the weight of the two-level safety index factors in the evaluation model,and the second-level fuzzy comprehensive evaluation is used to conduct the first evaluation of the five safety index factors corresponding to the second level that affect the safe driving risk.The type fuzzy set is used to describe and analyze the safety risk conditions of the five driving stages:starting,accelerating,constant speed,decelerating and stopping.Thirdly,according to the results of the first evaluation,the five safety risk influencing factors in the five driving stages are analyzed for their respective impacts on safe driving,and the discrete type-2 fuzzy comprehensive evaluation is used to conduct a second evaluation of safe driving risks,and establish a model of vehicle safety driving control under the discrete type-2 fuzzy set;describes the evolution process of safe driving risks under different control measures,and forms the language dynamics trajectory.Finally,analyze the safety risk situation of the vehicle in the five driving stages through examples,evaluate the safety risk of vehicle driving,discuss the risk factors of the vehicle in the accelerated driving state,and take corresponding control measures to analyze the safety risk of vehicle driving after the implementation of control,the effectiveness of the management and control model is verified.Based on the discrete type-2 fuzzy set and fuzzy comprehensive evaluation method,a model is established for safety driving evaluation of smart cars,the impact of safe driving risk is analyzed,the risk of safe driving of smart cars is managed and controlled.It provides basis and new ideas for the evaluation and control of the safe driving of smart cars.
