1409 機関・CVT 統合制御における STR を用いた空燃比制御システムの検討

抄録

When CVT was equipped with the engine, fuel consumption of the car becomes economical while the throttle valve angle and gear ratio of CVT were controlled simultaneously. Fuel consumption becomes economical at transient state by Engine-CVT consolidated control, therefore, accurate control of transient air fuel ratio (A/F) also becomes important issue under such control. From such point of view, STR was used to construct the A/F control system for enhancing the λ(air excess ratio) controllability and robustness against disturbance. Experimental investigation was carried out and expected result was obtained.
