Research On Some Problems Of Automobile Collision Protector Based On Fuzzy Control

With the rapid development of our modern society,the number of motor vehicles continues to increase.The resulting problem is that the number of traffic accidents continues to grow,which has aroused the broad concern in the society.As the economy continues to grow,the number of motor vehicles will keep increasing,and the traffic safety problem will become more severe.Therefore,the research on automobile anticollision control systems has important practical significance.This paper mainly studies the principle of automobile anti-collision control system,and applies the fuzzy control theory to the automobile anti-collision control system.Based on the principle of fuzzy control,this paper establishes the corresponding automobile anti-collision controller.Then,the simulation and emulation of the established controller are carried out,and the corresponding results and several defuzzification methods are analyzed and evaluated.The specific work of this paper is as follows:1.The problem of the automobile anti-collision is treated with fuzziness,and the input and output variables of the automobile anti-collision system are transformed into fuzzy input and output variables.At the same time,we need to get the data needed for the research.2.Based on the established principle of the membership function of fuzzy controller,the types and corresponding parameters of the membership function of each fuzzy variable are determined.Then,the fuzzy control rules needed in this paper are constructed according to the established method of fuzzy control rules.3.Fuzzy reasoning and deducing are applied on fuzzy control rules.Simulations and emulations are done by using the Matlab,and the results are visualized.Then,the determined membership function parameters are adjusted based on the results.Lastly,several methods of defuzzification are analyzed and compared.As far as the result of the simulation experiment is concerned,the output result of the model is in line with the situation of actual driving,so it is practical and feasible to use the fuzzy control method in the automobile anti-collision device.
