项目摘要

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.

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，并制造出具有优越驾驶性能和能源效率的实际车辆。与发动机汽车相比，电动汽车具有三个优点，即（1）扭矩响应非常快。（2）我们可以轻松地知道产生的电机扭矩，以及（3）可以分布式安装电机。我们制作了新车辆“CADWELL” EV”通过电压源型BLDC电机驱动来研究这些优点，并进行了详细的实际实验。实际上，(A)使用UOT March II进行了详细的实验，对轮胎和路面之间的附着力控制原理进行了研究和推广。车身侧滑角估计已得到改进。 UOT March II 具有光学车速传感器、偏航率传感器和加速度传感器。 (B)新型汽车“CADWELL”的附着力控制为了提高附着力，可以有效地实现分绕直流电机的特性。 “CADWELL”旨在通过使用BLDC电机来实现这一特性。它于2004年10月竣工，并经常进行重新设计。最后证明了所提方法的优越性能。与此同时，使用 MG 集进行了基础实验研究。
