PROBLEM TO BE SOLVED: To provide a slip control device that suppresses tire slip that occurs at the time of acceleration and deceleration, etc., and also suppresses pitching vibration of a vehicle body.SOLUTION: The slip control device includes slip ratio calculation means 16 for calculating a slip ratio using a wheel rotation speed and a vehicle speed, and slip ratio control means 17 for executing slip ratio control so that the magnitude of the slip ratio does not exceed the magnitude of a slip ratio limit value. The slip control device further includes slip ratio limit value changing means 18 that can change the magnitude of the slip ratio limit value, and pitching vibration detecting means 19 for detecting pitching vibration of a vehicle body. Upon detection of the pitching vibration of the vehicle body while the slip ratio control is executed, the slip ratio limit value changing means 18 lowers the magnitude of the slip ratio limit value of at least one or more wheels 2 and 3 of wheels for which the slip ratio control is executed.SELECTED DRAWING: Figure 2

    【課題】 加速または減速する際などに発生するタイヤスリップを抑制するとともに、車体のピッチング振動も抑制することができるスリップ制御装置を提供する。【解決手段】 車輪回転速度と車速を用いてスリップ率を算出するスリップ率演算手段16と、スリップ率の大きさがスリップ率制限値の大きさを超えないようにスリップ率制御を行なうスリップ率制御手段17とを備える。前記スリップ率制限値の大きさを変更可能なスリップ率制限値変更手段18、および車体のピッチング振動を検出するピッチング振動検出手段19を設ける。前記スリップ率制限値変更手段18は、スリップ率制御が実行されているときに車体のピッチング振動を検出した場合に、スリップ率制御が実行されている車輪の内の少なくとも1輪以上の車輪2,3のスリップ率制限値の大きさを低下させる。【選択図】 図2
