The Parameter Optimizing Research Of The Vehicle Dynamic Driving System

The vehicle can not be replaced in modern transportation, theimprovement of the vehicle's dynamic characteristics and fuel economicalefficiency is meaningful for the development of the economic and energysources saving.The vehicle's start acceleration time at the former place is consideredas the index of the dynamic characteristics, and the fuel specificconsumption is considered as the index of fuel economical efficiency, theweighted value of the dynamic characteristics and fuel economicalefficiency is considered as the integrated value index, the weighted value isdecided by the market factor, so the integrated value index is kept close tothe real market situation. Based on the setting up of the math model of themotor and driveline, a systematic and full math model of the driving systemis brought forward, so the simulated calculating precision of the dynamicand fuel economical efficiency is improve greatly.Based on the former work, the different grade of the driving ratio andthe main driving ratio is selected as the design variable, and the startacceleration time at the former place and the fuel consumption at the multiwork condition is selected as the multi optimizing target function, and themaximum dynamic factor is selected as the fuzzy describing restrictcondition, and the fuzzy optimizing model of the driveline is set up by thisway.,...
