Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress reduction of a rotational frequency right after a clutch starts sliding in starting.SOLUTION: A wheelie determination device includes: a pre-wheelie state determination unit configured to determine whether a vehicle is in a pre-wheelie state by comparing a vehicle body speed to a road surface with a peripheral speed of a front wheel; and a wheelie amount determination unit configured to calculate an angular change amount of the vehicle body in a rotational direction in which the front wheel separates from the road surface, from the time point that it is determined to be in the pre-wheelie state, as a wheelie amount that is a floating amount of the front wheel to the road surface.SELECTED DRAWING: Figure 4 【課題】発進時におけるクラッチの滑り始め直後の回転数落込みを抑制する。【解決手段】ウィリー判定装置が、路面に対する車体速度と前輪の周速度とを比較し、乗物がウィリー前状態であるか否かを判定するウィリー前状態判定部と、前記ウィリー前状態と判定された時点からの、前記前輪が前記路面から離れていく回転方向における前記車体の角度変化量を、前記路面に対する前記前輪の浮上り量であるウィリー量として算出するウィリー量判定部と、を備える。【選択図】図４
