Funding: 2015: $105,000
2016: $100,700
2017: $105,000

Project Member(s): Luo, Z.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2015

Summary: The aims of this project are to study a newly proposed clutchless power-shifting transmission (CPT) for hybrid and electric vehicle applications, 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 will significantly reduce the efficiency losses present in modern vehicles and establish new techniques for achieving gear and mode changes that do not rely on wet friction clutches. These novel technologies will provide new direction for developing the next generation of very efficient automotive powertrain technologies.
