This work presents the modeling and computer simulation of a novel hybrid transmission with a mechanical reverse driving mode, including an engine, a motor, a simple planetary gear train, and a Ravigneaux planetary gear train. Based on the given teeth number, the reduction ratios of all the clutching condition are acquired. The feasibilities of mode shifts among the clutching conditions are analyzed. Then, a modified rule-based control strategy is introduced. Subject to the vehicle condition, speed command, and predicted equivalent fuel consumptions, the most fuel economy clutching condition is selected by the control strategy. And, a computer model is developed using SIMULINK. Two popular driving cycles are applied to the simulation model, and the simulation results of the novel hybrid transmission are competitive with the existing hybrid electric vehicle models.
