项目摘要

Novel motion control techniques for Electric Vehicle (EV) by utilizing the electric motor's quick torque generation were researched. As an EV is driven by electric motors, it has the following three remarkable advantages: 1) motor torque generation is fast and accurate; 2) motors can be installed in two or four wheels; and 3) motor torque can be known precisely. These advantages enable us to easily realize: 1) high performance antilock braking system and traction control system with minor feedback control at each wheel; 2) chassis motion control like direct yaw control; and 3) estimation of road surface condition. In the past, we made test vehicles UOT March-I and II, and Cadwell-EV, and confirmed the effectiveness of the proposed methods. In this research project, we have made three C-COMS's which run only by super-capacitors. Super capacitor to drive these vehicles has great advantages in: 1) extremely long life; 2) large current charge and discharge; 3) environmental friendly material usage; and 4) remaining energy can be known from terminal voltage. C-COMS can nun more than 20 minutes by 30-second charge. It will solve the biggest problem of EV and may change our life-style. We performed developments in (1) TCS (traction control) based on MFC, (2) Slip prevention using Back-EMF Observer, (3) Hybrid ABS and TCS, (4) Adhesion Control emulating Separately Excited DC Motor's Property, (5) Estimation and Control of Body Slip Angle R, (6) DYC based on Yaw Moment Observer, (7) Estimation of g Gradient and Peak μ Estimation using Brush Model and Driving Force Observer, (8) Realtime Speed Pattern Generator to Improve Ride-comfort using Driver's Will Estimation, (9) Driving Force Distribution Control based on Estimation of Side Force, and so on.

研究了利用电动机快速产生转矩的电动汽车运动控制新技术。由于电动汽车是由电动机驱动的，它具有以下三个显著的优点：1）电动机扭矩产生快速准确; 2）电动机可以安装在两个或四个车轮上; 3）可以精确地知道电动机扭矩。这些优点使我们能够轻松实现：1）高性能防抱死制动系统和牵引力控制系统，每个车轮都有少量反馈控制; 2）底盘运动控制，如直接偏航控制; 3）路面状况估计。在过去，我们做了测试车辆UOT March-I和II，以及Cadwell-EV，并证实了所提出的方法的有效性。在本研究计画中，我们制作了三个仅以超级电容器运作的C-COMS。超级电容驱动这些车辆具有很大的优势：1）极长的寿命; 2）大电流充电和放电; 3）环保材料的使用; 4）剩余能量可以从终端电压中得知。C-COMS可以在30秒的充电时间内运行20分钟以上。它将解决电动汽车最大的问题，并可能改变我们的生活方式。我们在（1）TCS方面进行了开发（2）基于反电动势观测器的防滑控制，（3）ABS和TCS混合控制，（4）模拟他励直流电机特性的附着力控制，（5）车身侧偏角R的估计和控制，（6）基于横摆力矩观测器的DYC，（7）使用刷子模型和驱动力观测器估计g梯度和峰值μ估计，（8）使用驾驶员意愿估计来改善乘坐舒适性的实时速度模式生成器，（9）基于侧力估计的驱动力分配控制，等
