To provide a vehicle which can secure a drive force at a start even if the vehicle is stopped by abrupt deceleration, and a stop time is short.SOLUTION: A vehicle having an engine, a drive-side pulley, a driven-side pulley, a continuously variable transmission having a transmission belt wound to the drive-side pulley and the driven-side pulley, a mechanical oil pump driven by the engine, and hydraulic control means which is supplied with original pressure from the mechanical oil pump, and controlling hydraulic pressure for operating the drive-side pulley and the driven-side pulley, comprises; calculation means for calculating a deviation amount between a gear change ratio of the continuously variable transmission immediately before a stop, and a maximum gear change ratio of the continuously variable transmission; engine control means for driving the engine by setting an engine rotation number high as the deviation amount is large in a vehicle stop state, and driving the engine; and gear change ratio control means for controlling the hydraulic control means so that the gear change ratio of the continuously variable transmission is changed toward the maximum gear change ratio in the vehicle stop state.SELECTED DRAWING: Figure 1 【課題】急減速によって停車し、且つ、停車時間が短い場合でも、発進時の駆動力を担保することができる車両を提供すること。【解決手段】エンジンと、駆動側プーリ、従動側プーリ、及び、駆動側プーリと従動側プーリとに巻き掛けられた伝動ベルトを備える無段変速機と、エンジンにより駆動される機械式オイルポンプと、機械式オイルポンプから元圧が供給され、駆動側プーリ及び従動側プーリに作用させる油圧を制御する油圧制御手段と、を備えた車両であって、停車直前における無段変速機の変速比と、無段変速機の最大変速比との乖離量を算出する算出手段と、停車状態において、乖離量が大きいほどエンジン回転数を高く設定してエンジンを駆動させるエンジン制御手段と、停車状態において、無段変速機の変速比を最大変速比に向かって変化させるように油圧制御手段を制御する変速比制御手段と、を備える。【選択図】図１
