Document Type and Number:
Japanese Patent JP2016173154
Kind Code:
A
Abstract:
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
