摘要
为了解决传统车用无级变速器在行驶过程中传动比动态控制精度低、承载能力差的问题,在保证无级变速器使用要求的前提下,为提高车辆变速系统承载能力,将新型双锥无级变速器引入车辆传动系统,并提出了针对新型双锥无级变速器的自适应模糊PID传动比控制系统,最后建立整车仿真平台,对新型双锥无级变速器自适应模糊PID控制系统可行性进行研究。研究结果表明,新型双锥无级变速器相对于传统金属带无级变速器承载能力较强,通过自适应模糊PID对安装有新型双锥无级变速器车辆进行控制时与使用传统PID控制相比,车辆实际传动比、车速均与目标传动比、车速贴合性较高,能够有效地提高新型无级变速器的控制效率。
In order to solve the problem of the dynamic low control accuracy and poor carrying capacity of vehicle traditional transmission ratio in the driving process,under the premise of ensuring the CVT use requirements,in order to improve the carrying capacity of the transmission system,the double conical CVT is introduced into vehicle transmission system,an adaptive fuzzy PID speed ratio control system of a new type of double conical CVT is proposed,finally the vehicle simulation platform is established,and the new double conical CVT adaptive fuzzy PID control system feasibility is researched. The results show that the new double conical CVT compared with traditional metal belt CVT has better carrying capacity,the adaptive fuzzy PID control model with double conical CVT vehicle compared to traditional PID control,the actual vehicle transmission ratio,speed are high consist with target transmission ratio,speed,which can effectively improve the control efficiency of a new type of double conical CVT.
