Abstract

Abstract:

In order to avoid power loss of continuously variable transmission system with reflux power and reduce vehicle jerk,a continuous power shift control strategy of continuously variable transmission system with reflux power was put forward.Aimed at shifting process,transmission efficiency and the opposite direction of continuously variable unit had impact on transmission output torque,a dynamics model of clutch engagement and disengagement course was established, and the range of clutch torque change ratio was calculated. Taking MATLAB/Simulink as the platform,simulation study of shifting process was carried out, the results indicate that jerk is less than 5m/s3 by adopting continuous power shift control strategy of continuously variable transmission system with reflux power.

Key words: vehicle, continuously variable transmission;clutch, control strategy

摘要：

为避免回流式无级变速器在无级与回流工况转换过程中动力中断,以减小对整车冲击度的影响,提出了回流式无级变速器动力连续转换的控制策略。针对转换过程中变速器效率和金属带功率流方向变化对输出转矩的影响,建立了转换过程中离合器接合、分离的动力学模型,确定了离合器扭矩变化率的限定范围。利用MATLAB/Simulink仿真平台,对回流-无级和无级-回流转换过程进行了仿真研究,结果表明：采用回流式无级变速器动力连续转换的控制策略,冲击度控制在5m/s3以内。
