Design And Simulation Of An Electric Learner-driven Vehicle About The Start Progress

Due to the environment pollution and energy problem of the world has become two bigproblems faced by the fuel automobile development,many Driving Schools start to modificationor purchase Electric Learner-driven Vehicle to save training costs. Through the fieldinvestigation of Driving Schools,We found that although the existing Electric Learner-drivenVehicle can meet the requirements of driving training on the power performance,it still has a bigdifference with the fuel cars on handling characteristics,especially the handling characteristics ofclutch during the start process. In the start process, the Electric Learner-driven Vehicle won’t beshake and even stop like the fuel cars due to the torque automatically adjusting characteristics ofDC motor.To solve such a problem, this article will finish the following work:(1) According to the dynamic property requirements of an Electric Learner-driven Vehicle,we choose the type of the drive motor and the power battery and matching their parameters, andthen make a Dynamic match to the Electric Learner-driven Vehicle, which could provide thenecessary data to the following Modeling and Simulation during the start progress.(2) Analyzing the differences between an Electric Learner-driven Vehicle and a fuel car andperformance requirements of an Electric Learner-driven Vehicle on a start process, and then setup a drive motor model and a clutch combination process model,which could provide the basisfor the next model building and simulation on a Start Progress.(3) Using the fuzzy control theory to build a model about high electromagnetic torque limit,electromagnetic torque decline and the motor stop control under the a sudden increase of loadtorque,and then take a simulation with the MATLAB software,and analyze the simulation results.
