| Abstract(J) | AVLの最適化ツールHYPOPはHBPTの燃費と所定速度軌道の最適化ツールである．この方式はギヤシフトと機関トルクの設定ポイントを制御変数に取り，PT全体での最適方策を見出す．本研究では48ボルトのベルトスターター発電機を持つマイルドHB車の構成に用いられ，ターゲット車両への適用で燃費最適化に向けた測定プロセスの短縮が得られた． Translation |
| Abstract(E) | AVL HYPOP optimization tool aims to determine HYbrid Powertrain Optimal Policy with respect to fuel consumption optimization and performance for a given speed trajectory, finite time horizon and initial SoC. Main interests of this approach is to consider both Gear shifting and E machine torque setpoint as control variables in a simultaneous way to find the global powertrain optimal policy. HYPOP model is a backward optimization tool based on Dynamic Programming and is applied in this paper to a Mild Hybrid configuration with 48V Belt Starter Generator (BSG) system and 7 gears DCT. HYPOP model is validated with respect to CRUISE forward model from AVL using a baseline conventional vehicle. Method, tools and process for creating optimal calibration set of the AVL embedded Control SW are described and applied on real target vehicle showing a shortened calibration process towards fuel consumption optimum. |
