ハイブリッド電気自動車のバッテリー充電状慴のシミュレーション（gps測定データの勾配置搎手法による）

摘要

This report evaluates a position of SOC (State of Charge) along with a down hill drive on a real world to its simulation on an emission chassis dynamometer with a gradient road load. On a down hill drive, a vehicle kinetic energy regenerates the battery continuously and an amount of charge volume which shifts the battery SOC up. Excessive charge is a negative factor for the battery life which is designed both a long term of life and a long distance of drive. This regenerating driving mode could not be evaluated on a flat road. A gradient drive way or a system forced energy into vehicle could evaluate the mode. To evaluate, on the one hand some necessary investigation is carried out to a realization of a down hill drive simulation on an emission chassis dynamometer and problems hitting upon the investigation has been clarified. On the other hand the real world data driving down hill is measured by HEV (Hybrid Electric Vehicle). The real world data collected by GPS (Global Positioning System) has fluctuated widely. This report proposes a method of spline compensation to the data for a chassis simulation test and reviews the results of the test to the real world mode and evaluates the studies. And further more study is carried out an applied chassis simulation.%地球環境問題に対して各方面で様々な取組みが行わrnれている．交通物流機械分野は，我が国のCO_2排出rn量の二割を占める．中でも自動車がその九割を占め，rn重点的な環境技術の構築が求められている．HEVrn（ハイブリッド電気自動車）は，この技術手段の一つrnとして2000年前後から実用化が進んでいる．HEVは，rn回生エネルギーを電池へ一時溜め込んで必要な時に出rn力できる機能がその最大の特徴であり，エネルギーのrn有効利用上から優れたシステムといえる．
