PROBLEM TO BE SOLVED: To provide a start control device for a vehicle that can secure transmissibility and responsiveness of driving force when an accelerator pedal is trod with a brake pedal being trod while parking the vehicle and then the brake pedal is released to start the vehicle.SOLUTION: When an accelerator pedal is trod with a brake pedal being trod while parking a vehicle with the brake pedal being trod, before the brake pedal is released, an electric oil pump is driven which is driven by a sub motor which is independent from a motor/generator and brought into a non-driven state while parking the vehicle so as to supply hydraulic pressure. Further, supply of hydraulic pressure from the electric oil pump can increase supply of hydraulic pressure to a second clutch which is arranged between the motor/generator and left and right driving wheels and transmits driving force of the motor/generator to the left and right driving wheels.SELECTED DRAWING: Figure 3A 【課題】停車中にブレーキペダルが踏み込まれたままアクセルペダルが踏み込まれ、その後ブレーキペダルを解放させて発進を行う場合に、駆動力の伝達応答性を確保することができる車両用発進制御装置を提供すること。【解決手段】ブレーキペダルが踏み込まれた停車中に、ブレーキペダルを踏み込んだままアクセルペダルが踏み込まれたとき、ブレーキペダルが解放される前に、モータ/ジェネレータとは別であって、停車中に非駆動状態になるサブモータによって駆動されて油圧供給を行う電動オイルポンプを駆動する。そして、電動オイルポンプからの油圧供給によりモータ/ジェネレータと左右駆動輪との間に配置され、発進時に、モータ/ジェネレータの駆動力を左右駆動輪へと伝達する第２クラッチへの供給油圧を増大する構成とした。【選択図】図３Ａ
