To provide a drive control device of an electric vehicle, which improves traveling stability of the vehicle when regenerative braking is performed during traveling on off-roads.SOLUTION: In a drive shaft request torque setting unit 25 configured to calculate drive shaft request torque of a vehicle 1 that performs regenerative braking on wheels 3, 5 by a front motor 4 and a rear motor 6 at the time of accelerator OFF, a drive wheel off determination unit 52 that determines leaving from the ground of the wheels 3, 5 of the vehicle 1, and a lowest drive torque control unit 55 that sets regenerative torque generated by the front motor 4 and the rear motor 6 are provided. In a case where wheel-off is determined when regenerative braking is performed during accelerator OFF, the lowest drive torque control unit 55 suppresses the regenerative torque compared to a case where leaving from the ground is not determined.SELECTED DRAWING: Figure 2

    【課題】不整地走行時に回生制動した際に、車両の走行安定性を向上させる電動車両の駆動制御装置を提供する。【解決手段】アクセルオフ時にフロントモータ4、リヤモータ6により車輪3、5を回生制動する車両1の駆動軸要求トルクを演算する駆動軸要求トルク設定部25において、車両1の車輪3、5の離地判定をする駆動輪離地判定部52と、フロントモータ4、リヤモータ6による回生トルクを設定する最低駆動トルク制限部55と、を備え、最低駆動トルク制限部55は、アクセルオフ時に回生制動を実行している際に、離地判定された場合には離地判定されていない場合よりも回生トルクを抑制する。【選択図】図2
