无级变速器速比控制的关键是确定目标速比,合理的目标速比能够提高无级变速器的换档性能和效率。本文研究了一种基于驾驶员意图识别的无级变速器速比控制方法,通过判断车辆行驶环境与驾驶员驾驶意图,确定最佳目标速比,控制无级变速器的速比变化。
The key to CVT control is to determine the target speed ratio. A reasonable target speed ratio can improve the gear shifting performance and efficiency of CVT. In this paper, a control method of continuously variable transmission speed ratio based on driver’s intention recognition is studied. By determining the driving environment of the vehicle and the driving intention of the driver, the optimal target speed ratio is determined and the speed ratio of the continuously variable transmission is controlled.
