Power-split hybrid transmission energetic and dynamic evaluation program

This paper focuses on the study of hybrid power-split transmission evaluation. The method proposed here is based on a generic formulation of the mechanical part of the transmission. The kinematics and inertia behaviors are introduced via two matrices and detailed for two power-split transmission examples. Then, the powertrain control problem is formulated in two steps: first, the optimal energy management problem is formulated, then, the difficult issue of controlling the transmissions in a multivariable way is explained. Each driving mode is studied because they each correspond to a specific set of objectives. In the last section, we present simulation results that emphasize the energetic and dynamic issues of such transmissions.
