Dual input clutchless power-shifting transmission for hybrid vehicles

该项目研究了一种新提出的用于混合动力汽车和电动汽车的无离合器动力换档变速器。它的目的是设计新的加电换挡方法和执行器，以实现CPT的最佳性能，并通过仿真和实验评估系统在稳态和暂态条件下的性能和响应。预计拟议中的变速器将显著降低现代汽车的效率损失，并建立新的技术，实现不依赖摩擦离合器的档位和模式转换。预计这些新技术将为开发下一代非常高效的汽车动力总成技术提供新的方向。

This project studies a newly proposed clutchless power-shifting transmission (CPT) for hybrid and electric vehicle applications. It aims to design new methods and actuators for power-on gear change to realise the best possible performance of the CPT, and through simulation and experimentation evaluate the system performance and response under both steady state and transient conditions. The proposed transmission is expected to significantly reduce the efficiency losses present in modern vehicles and establish new techniques for achieving gear and mode changes that do not rely on friction clutches. It is anticipated that these novel technologies will provide new direction for developing the next generation of very high efficiency automotive power train technologies.
