To suppress sudden change in acceleration in a case of accelerating a vehicle due to rotation speed change of an engine.SOLUTION: In a power train, an input shaft of a continuously variable transmission is interlocked with an output side of a flywheel that smoothes the torque fluctuation of an engine, and the output of the continuously variable transmission is interlocked with drive wheels of a vehicle. The power train is provided with one control line (indicated by a broken line) that increases torque at an engine speed Neo, and the other control line 1c. The input shaft of the continuously variable transmission is provided with control means that sets load power P1 to the engine. The control at the time when the operation of the engine shifts to the other control line via the one control line is performed so that the relation between an engine output Pe on the other control line, the power P1 set on the input shaft, and a predetermined power value dPe satisfies the following equation: P1=Pe-dPe.SELECTED DRAWING: Figure 5
【課題】エンジンの回転速度変化に伴う車両加速時の加速度急変を抑制する。【解決手段】エンジンのトルク変動を平滑化するフライホイールの出力側に無段変速機の入力軸が連動し、前記無段変速機の出力は車両の駆動輪に連動しているパワートレインにおいて、エンジン回転速度Neoにてトルクを増大する一方の制御線(破線で示す)と、他方の制御線1cを設け、前記無段変速機の入力軸へ前記エンジンへの負荷動力P1を設定する制御手段を設け、前記エンジンの作動が、前記一方の制御線を経由して前記他方の制御線上へ移行する際の制御は、前記他方の制御線上のエンジン出力Pe、前記入力軸へ設定する動力P1および所定の動力値dPeとの関係を、P1=Pe−dPeの関係によって制御を行う。【選択図】図5
