Abstract

This paper proposes the new speed control method of electric vehicles by generating the longitudinal speed pattern for improving the ride comfort against the longitudinal acceleration/deceleration. Since the longitudinal acceleration/deceleration of EVs causes the discomfort of passengers, reducing such bad effect of acceleration/deceleration acting on passengers is very important for not only the ride comfort of passengers but also vehicle running safety. The proposed method is applying the general optimal control theory and it generates the speed pattern for improving the passenger ride quality based on evaluating the variations of acceleration and the jerk which is time derivative of the acceleration. The effectiveness of the present method is demonstrated through numerical experiments compared with some conventional methods.
提高乘客乘坐质量的电动汽车速度控制方法
本文提出了一种新的电动汽车速度控制方法,通过生成纵向速度模式来提高纵向加减速时的平顺性。由于电动汽车的纵向加减速会引起乘客的不适,因此减少这种加减速对乘客的不良影响不仅对乘客的乘坐舒适性至关重要,而且对车辆的运行安全也至关重要。该方法应用一般最优控制理论,通过对加速度的变化和加速度的时间导数——加速度加速度的变化进行评估,生成改善乘客乘坐质量的速度模式。通过数值实验与传统方法进行了比较,验证了该方法的有效性。
