碩士 === 國立臺南大學 === 綠色能源科技研究所碩士班 === 100 === The paper proposed the development and traction control system (TCS) of a front-wheel drive electric vehicle (EV). Two in-wheel motors were utilized in the system to construct a power-scattered EV. The permanent magnet servo motor can individually control the motor power output and immediately limit the torque individual. This paper imposed the maximum transmission torque estimation (MTTE) system as the core of TCS for preventing the vehicle skid. The control algorithm is embedded in a high speed microprocessor, which can real-timely monitor feedback signals. In the torqure ouput, a plenary gearbox was employed to amplify the motor torque. This paper also used the simulation software “CarSim” to analyze the anti-skid performace of the prototype EV which is called Corsa-EV. The crucial issues include vehicle dynamics construction and anti-skid evaluation. From the results of simulation, it is obvious that the propsed EV can achieve an accetptable performance of stability and safety with the enhancement of MTTE.
