To provide a traction control device which dispenses with a switching operation by a switch, can properly detect the stuck state in the time of stuck, has the excellent escape property and is advantageous regarding a manufacturing cost.SOLUTION: A traction control device suppresses idling of drive wheels with the first engine control that performs torque down of an engine when a slip amount of the drive wheels excesses a prescribed threshold and/or the first brake control that actuates braking of the drive wheels whose slip amount excesses the prescribed threshold to increase the torque distribution of other drive wheels. The traction control device determines a stuck state (120) when a prescribed times elapses with zero vehicle speed (110;YES) during the operation of the first engine control or the first brake control (100;YES), and shifts to the second engine control with the smaller torque down amount than that of the first engine control and to the second brake control with the larger brake force than that of the first brake control (130).SELECTED DRAWING: Figure 2

    【課題】 スイッチによる切替え操作が不要であり、スタック時にスタック状態を適切に検知でき、脱出性に優れ、製造コスト面でも有利なトラクション制御装置を提供する。【解決手段】 駆動輪のスリップ量が所定閾値を超過した場合にエンジンのトルクダウンを行う第1のエンジン制御、および/または、スリップ量が所定閾値を超過した駆動輪のブレーキを作動させて他の駆動輪のトルク配分を増加させる第1のブレーキ制御により、駆動輪の空転を抑制するトラクション制御装置において、第1のエンジン制御または第1のブレーキ制御の作動中(100;YES)に、車速ゼロで所定時間経過した場合(110;YES)にスタック状態と判定し(120)、第1のエンジン制御よりもトルクダウン量が小さい第2のエンジン制御、および、第1のブレーキ制御よりも制動力が大きい第2のブレーキ制御に移行する(130)。【選択図】図2
