PROBLEM TO BE SOLVED: To provide a vehicular state quantity estimation device having a calculation device which calculates state quantities on at least springs of a vehicle on the basis of wheel speeds of left and right front wheels and of left and right rear wheels detected by a wheel speed detection device.SOLUTION: An calculation device calculates wheel speed components of left and right wheel in phase and of left and right wheel opposite phase regarding front wheels and rear wheels, and calculates a pitch angular speed and a yaw angular speed on each spring on the basis of the wheel speed components of left and right wheel in phase and of left and right wheel opposite phase. The calculation device, regarding the front wheels and the rear wheels, calculates vertical stroke components of in phase and of opposite phase of left and the right suspensions, and calculates a vertical speed and a roll angular speed on each spring on the basis of the vertical stroke components of in phase and of opposite phase of the left and the right suspensions.SELECTED DRAWING: Figure 2
【課題】車輪速検出装置により検出された左右前輪及び左右後輪の車輪速に基づいて車両の少なくともばね上の状態量を演算する演算装置を有する車両の状態量推定装置を提供する。【解決手段】演算装置は、前輪及び後輪について左右輪同相及び左右輪逆相の車輪速成分を演算し、左右輪同相及び左右輪逆相の車輪速成分に基づいて、それぞればね上のピッチ角速度及びヨー角速度を演算する。演算装置は、前輪及び後輪について左右サスペンションの同相及び逆相の上下ストローク成分を演算し、左右サスペンションの同相及び逆相の上下ストローク成分に基づいて、それぞればね上の上下速度及びロール角速度を演算する。【選択図】図2
