Advanced Control Technology for Near future Vehide driven by Electricity

本研究旨在开发只有电动汽车（PEV，HEV和FCEV......）才能实现的先进电气控制技术，电动汽车与内燃机汽车相比有三大优势，即：（1）扭矩响应非常快。(2)We（3）电动机的分布式安装成为可能，为了研究这种优点，我们制作了一辆由电压源型无刷直流电动机驱动的新型汽车“CADWELL EV”，并进行了详细的实际实验。实际上，（A）使用UOT March II的详细实验研究和推广了轮胎与路面之间的粘附控制原理。车身侧偏角估计得到改进。UOT March II具有光学车速传感器、横摆角速度传感器和加速度传感器。并在实验中得到成功应用。（B）新型车辆“CADWELL“的附着力控制为了提高附着力，实现独立绕线直流电动机的特性是有效的。“CADWELL”旨在通过使用BLDC电机来实现这一特性。它于2004年10月完工，并经常重新设计。最后，证明了该方法的上级性能。与此同时，使用MG集进行基础实验研究。

This research aims to develop advanced electrical control technologies which can be realized only by EV (PEV,HEV and FCEV....), and to make actual vehicles which have superior drivability and energy efficiency.Electric vehicle has three advantages comparing to Engine vehicle, i.e.,(1)Torque response is very fast.(2)We can know the generated motor torque easily, and(3)Distributed installation of motors is possible.We made a new vehicle "CADWELL EV" driven by voltage source type BLDC motor to investigate such advantages, and performed detailed and actual experiments. In actuality,(A)Detailed experiments using UOT March IIPrinciple of adhesion control between tire and road surface was investigated and generalized. Body slip angle estimation has been improved. UOT March II has the optical vehicle speed sensor, yaw-rate sensor and acceleration sensors. They were used in experiments successfully.(B)Adhesion control by the New Vehicle "CADWELL"To improve adhesion, it is effective to realize the characteristics of separately wound DC Motor. "CADWELL" aims to realize this characteristic by using BLDC motor. It was completed in October,2004, and has been often redesigned. Finally, superior performance of the proposed method was proved. In parallel, basic experimental study using MG set was performed.
