| Abstract(J) | 電気自動車用CVT制御では，経験的に設計された変速マップが一般的に用いられているが，その最適性は十分に検討されていない．本研究では，最適化手法により各走行条件における最適CVT変速比を算出し，既存CVTマップとの差異を解析した．さらに，決定木を用いて補正領域の分類を行い，各領域に対する補正マップを構築することで，既存CVT変速マップの改良手法について検討した． Translation |
| Abstract(E) | For EV CVT control, shift maps are generally designed empirically, and their optimality has not been sufficiently investigated. In this study, optimal CVT ratios under various driving conditions were calculated using an optimization method, and the differences from the conventional CVT map were analyzed. In addition, correction regions were classified using a decision tree, and correction maps for each region were constructed to investigate a method for improving conventional CVT shift maps. |
