PROBLEM TO BE SOLVED: To provide a vehicular drive control system with a capability of balancing between the reduction of loss in a DC-DC converter and the securing of drivability.SOLUTION: A drive control system includes: a DC-DC converter connected to a battery being a DC power source; an FrMG that is connected to the DC-DC converter and is a first motor for driving either one of front and rear wheels; an RrMG that is connected to the battery and is a second motor for driving a wheel different from the one driven by the FrMG; and a control device for performing step-up intermittent control of the DC-DC converter. In a case where vehicular required drive force is increased while the DC-DC converter is stopped under the step-up intermittent control from required drive force that is required when starting a step-up operation stop, the control device controls the drive force of the FrMG so as to not exceed a second given value that is the drive force of the FrMG applied when variation of the required drive force is at a first given value, if the aforementioned increase is equal to or more than the first given value, and causes the RrMG to generate a residual amount of the required drive force.

    【課題】車両の駆動制御システムにおいて、DC/DCコンバータの損失低減と運転性の確保との両立を図ることである。【解決手段】駆動制御システムは、直流電源であるバッテリに接続されるDC/DCコンバータ、DC/DCコンバータに接続され前輪及び後輪の一方の車輪を駆動する第1モータであるFrMG、バッテリに接続されFrMGとは異なる車輪を駆動する第2モータであるRrMG、及びDC/DCコンバータの昇圧間欠制御を行う制御装置とを含む。制御装置は、昇圧間欠制御によるDC/DCコンバータの停止中に車両の要求駆動力が昇圧動作停止を開始した際の要求駆動力から増大した場合に、その変動が第1の所定値以上の場合には、FrMGの駆動力を、要求駆動力の変動が第1の所定値のときのFrMGの駆動力である第2の所定値を超えないようにし、要求駆動力の残余分をRrMGに発生させるように制御する。【選択図】図1
