Study on Vehicle Control and Energy Consumption of Light Weight Electric Vehicle Using Full Vehicle Model Based on Modelica Language

Modelica 言語によるフルビークルモデルを用いた軽量電気自動車の車両運動とエネルギー消費に関する研究

This paper describes a full vehicle model for model-based development of a future light weight electric vehicle using Modelica language to evaluate both vehicle dynamics and energy consumption. Modelica language has a beneficial feature that allows various engineering fields to be simulated simultaneously in a unified model. Utilizing this advantage, the model was composed of a vehicle, control systems, a torque vectoring driveline, and motors/invertors, with considering each loss. Simulations of a driving straight ahead in crosswind and a steady state cornering were carried out, and the results clarified the trade-off relationship between vehicle attitude and energy consumption, and the breakdown of energy consumption quantitatively.本研究では,異なる物理領域を統合して記述可能なModelica言語を用いて,軽量EVモビリティのフルビークルモデルを構築した.タイヤ損失や空力抵抗損失に加え,トルクベクタリング機械損失,およびモータ,インバータ電気損失のモデルを組み込み,車両運動とエネルギー消費の関係を定量的に評価した.
