PROBLEM TO BE SOLVED: To provide a flywheel regeneration system which suppresses the interruption of a brake force and a drive force.SOLUTION: In a flywheel regeneration system in which a continuously variable transmission 3, a first friction fastening element CLfw and a second friction fastening element CLre are arranged between a flywheel 2 and drive wheels 6, and which controls a fastening torque capacity of the first friction fastening element CLfw, and accumulates motion energy to the flywheel 2 by down-shifting the continuously variable transmission 3, the flywheel regeneration system comprises brake force generation means 8 which can generate a brake force by bringing the first friction fastening element CLfw and the second friction fastening element CLre into power transmission states. When the brake force generation means 8 accumulates the motion energy to the flywheel 2, the brake force generation means brings the second friction fastening element CLre into the power transmission state during a period in which a change of an actual gear change ratio of the continuously variable transmission 3 accompanied by the down-shift is started after the fastening of at least the first friction fastening element CLfw is finished.SELECTED DRAWING: Figure 1
【課題】制動力、駆動力の途切れを抑制するフライホイール回生システムを提供する。【解決手段】フライホイール2と駆動輪6との間に、無段変速機3、第1摩擦締結要素CLfw、及び第2摩擦締結要素CLreを配置し、第1摩擦締結要素CLfwの締結トルク容量を制御し、無段変速機3をダウンシフトすることでフライホイール2に運動エネルギーを蓄えるフライホイール回生システムであって、第1摩擦締結要素CLfwと第2摩擦締結要素CLreとを動力伝達状態とすることで制動力を発生可能な制動力発生手段8を備え、制動力発生手段8は、フライホイール2に運動エネルギーを蓄える際に、少なくとも第1摩擦締結要素CLfwの締結が完了してから、ダウンシフトに伴う無段変速機3の実変速比の変化が開始されるまでの間、第2摩擦締結要素CLreを動力伝達状態とする。【選択図】図1
