To provide an electrically driven dump truck capable of improving safety of vehicle operation by suppressing hunting from occurring.SOLUTION: An electrically driven dump truck comprises a drive torque command value calculation part 103 which outputs a drive torque command value, and a drive torque correction value calculation part 105 which calculates a drive torque correction value for increasing or decreasing the drive torque command value, and is configured to: set, based upon a combination of a loading state determined from vehicle weight information and vessel position information, the weight and gravity center height of the electrically driven dump truck 100; determine whether drive torque of a travel device 106 becomes equal to or less than zero when the drive torque correction value calculated by the drive torque correction value calculation part based upon the set weight and gravity center height is applied to the drive torque command value; and calculate and apply, when it is determined that the drive torque is equal to or less than zero, to the drive torque command value a drive torque correction value for output for making the drive torque larger than zero.SELECTED DRAWING: Figure 2

    【課題】ハンチングの発生を抑制することによって車両運行の安定性を向上することができる電気駆動ダンプトラックを提供すること。【解決手段】駆動トルク指令値を出力する駆動トルク指令値算出部103と、駆動トルク指令値を増減するための駆動トルク補正値を算出する駆動トルク補正値算出部105とを備え、車両重量情報により判定される積荷状態とベッセル位置情報との組み合わせに基づいて電気駆動ダンプトラック100の重量及び重心高さを設定するとともに、設定した重量及び重心高さに基づいて駆動トルク補正値算出部で算出した駆動トルク補正値を駆動トルク指令値に適用した場合に走行装置106の駆動トルクがゼロ以下になるかどうかを判定し、駆動トルクがゼロ以下になると判定された場合には、駆動トルクをゼロより大きくするための出力用駆動トルク補正値を算出して駆動トルク指令値に適用する。【選択図】 図2
