Study on Stepless Speed Regulation Actuation Concept and Simulation of the Mini-car Power Split Automatic

To improve the performance of the power split automatic transmission (PSAT), the power split automatic transmission (PSAT) for mini-car is researched. Several projects on stepless speed regulation and power split are analyzed. And the fully electronic regulation power split continuously variable transmission is the final project presented in this paper. The simulation results indicate that the fully electronic regulation power split continuously variable transmission (CVT) can raise the engine efficiency and fuel economy.
