DEVELOPMENT OF AN INSTANTANEOUS POWERTRAIN OPTIMAL CONTROL METHOD FOR E-CVT BASED HYBRID ELECTRIC VEHICLES

摘要

Among HEV configurations, the electronic-continuously variable transmission (e-CVT) architecture can optimally blend power from an engine and electric motor/generators. Design of an e-CVT powertrain is a challenging and time-consuming task due to the system complexity and the multi-disciplinary nature of the design problem. In this work, an approach to develop the system-optimal based instantaneous control strategy is proposed. The approach is developed using a model-based design method. The complete process includes model generation, control implementation, and system simulation. This work can be applied to developing optimal control strategy for e-CVT based transmissions as well as a wide range of other hybrid configurations.
