PROBLEM TO BE SOLVED: To provide a vehicle power transmission system, a vehicle, and a vehicle power transmission method, capable of simplifying and facilitating control for avoiding torque shock when a fluid joint is locked up, in a vehicle transmitting the power of an internal combustion engine to wheels through a fluid joint equipped with a lock-up function, a clutch, and a transmission.SOLUTION: When a fluid joint 14 is locked up, while rotation number change on an output side of the fluid joint 14 is detected, a clutch 11 is switched from a completely connected state to a half-clutch state to lower transmission possible torque. In a first half-clutch state when the rotation number change on the output side of the fluid joint 14 is detected, the locking-up of the fluid joint 11 is started and completed, and after the completion, shifting engine operation which shifts engine speed and engine output torque to target engine speed Nt and target torque Qt after the locking-up is performed, and during or after the shifting engine operation, the clutch 11 is brought to the completely connected state.SELECTED DRAWING: Figure 2

    【課題】内燃機関の動力を、ロックアップ機能を備えた流体継手、クラッチ、トランスミッションを介して車輪に伝達する車両において、流体継手をロックアップするときのトルクショック回避のための制御を単純化及び簡単化できる、車両の動力伝達システム、車両、及び、車両の動力伝達方法を提供する。【解決手段】流体継手14をロックアップするときに、流体継手14の出力側の回転数変化を検出しながら、クラッチ11を完接状態から半接状態にして伝達可能トルクを低下させて、流体継手14の出力側の回転数変化の検出時の第1半接状態で流体継手11のロックアップを開始して完了し、この完了後にエンジン回転数及びエンジン出力トルクをロックアップ後の目標回転数Nt及び目標トルクQtに移行する移行用エンジン運転を行い、この移行用エンジン運転の際中又は終了後にクラッチ11を完接状態にする。【選択図】図2
