PROBLEM TO BE SOLVED: To realize start performance with a start lag and a clutch engagement shock suppressed in starting a vehicle.SOLUTION: An FF hybrid vehicle, having a second clutch disposed between a motor-generator and a V-belt-type stepless transmission, includes: start determination means (S11, S12 in FIG. 2) for determining a start operation of a driver; differential rotation determination means (S14 in FIG. 2) for determining the presence/absence of a differential rotation between the motor-generator and the V-belt-type stepless transmission when a start operation of a driver is determined; and start control means (S15-S18 in FIG. 2). If it is determined that there is no differential rotation, the start control means engages the second clutch completely and then starts the vehicle by generating drive force of the motor-generator, while if determined that there is a differential rotation, starts the vehicle by gradually engaging the second clutch allowing slippage thereof in a state where the drive force of the motor-generator is generated.
【課題】発進時、発進ラグやクラッチ締結ショックを抑えた発進性能を達成すること。【解決手段】モータ/ジェネレータとVベルト式無段変速機の間に第2クラッチを備える。このFFハイブリッド車両において、運転者による発進操作を判断する発進判断手段(図2のS11,S12)と、運転者による発進操作が判断されると、モータ/ジェネレータとVベルト式無段変速機との間の差回転の有無を判断する差回転判断手段(図2のS14)と、発進制御手段(図2のS15〜S18)と、を備える。発進制御手段は、差回転が無いと判断されると、第2クラッチを完全締結してからモータ/ジェネレータの駆動力を発生して発進し、差回転が有ると判断されると、モータ/ジェネレータの駆動力を発生した状態で第2クラッチを滑らせながら徐々に締結して発進する制御を行う。【選択図】図2
