Abstract
【解決手段】寿命仕事量算出手段15は、温度履歴分布算出手段14により演算されたバッテリの温度履歴とメモリ11に予め保存されている単位寿命仕事量とに基づいて、バッテリの寿命仕事量を演算する。仕事量増加速度許容値算出手段16は、この寿命仕事量と走行距離とに基づいて、仕事量増加速度の許容値を演算する。比較手段17は、バッテリの積算放電量と走行距離とに基づいて、実仕事量増加速度を算出し、実仕事量増加速度と仕事量増速度加許容値とを比較する。バッテリ出力制限手段18は、実仕事量増加速度が仕事量増加速度許容値よりも大きい場合には、通常走行態様において必要に応じて制限されるバッテリの出力から、実仕事量増加速度と仕事量増加速度許容値との差に基づいた制限値だけ出力をさらに制限する。
【選択図】図2
Description
まず、第1実施形態における車両の構成を説明する。図1は、車両の動力伝達系統および制御系統を概略的に示すブロック図である。図1に示すように、本実施形態の車両1は、いわゆるハイブリッド車両であり、エンジン2と、このエンジン2の出力軸上に配設され、エンジン2に直結された電動機(モータ)3と、エンジン2および電動機3の出力軸に連結された変速機(トランスミッション)4と、変速機4の出力軸に連結されたディファレンシャル機構5と、このディファレンシャル機構5に左右のアクスルシャフト6R、6Lを介して連結された駆動輪である左右の前輪7R、7Lと、従動輪である左右の後輪8R、8Lとを備える。
仕事量増加速度の許容値
=A×a/100+B×b/100+C×c/100+D×d/100
A=W1/Dt
なお、温度ゾーン1〜4の寿命仕事量をそれぞれW1〜W4とし、対応する単位距離当たりの寿命仕事量をA〜Dとすると、W2とB、W3とC、W4とDについても同様の関係が成り立つ。ここで、図3(a)の各温度ゾーンの分布割合を用いると、W1〜W4とWtとの間には以下のような関係が成り立つ。
Wt=W1×a/100+W2×b/100+W3×c/100+W4×d/100
以下、本発明の第2実施形態を説明する。なお、第2実施形態における車両も第1実施形態の車両1と同様の構成であり、第2実施形態における電子制御ユニットも第1実施形態の電子制御ユニット10と同様の構成であるので、車両および電子制御ユニットの図示およびその説明を省略する。
