Abstract

This paper presents four novel parallel hybrid transmissions based on the structures of three and four-speed automatic transmissions using seven-link Ravigneaux gear train. The proposed designs have some advantages while using conventional automatic transmission structures such as simple mechanical layout, compact design, and flexible operation. They are generally able to perform five primary operation modes; electric motor mode, power mode, power split mode, engine mode, and regenerative braking mode. By using an electronic power control unit, the switching between operation modes is controlled based on vehicle operating conditions. They can either operate as parallel hybrid transmissions or conventional three or four-speed automatic transmissions in the engine mode. One of the new hybrid transmissions is presented as a numerical example to illustrate the working principle, kinematics, static torque and power flow of each operation mode. Furthermore, a feasible clutching logic for control strategy is developed. And, the results show that the proposed design is feasible.
