摘要： PROBLEM TO BE SOLVED: To smoothly engage a lock-up clutch 25 by making engagement timing of the same appropriate during low speed travel after start in a power transmission for a vehicle having an engine 61 equipped with a turbocharger 62 and a fluid coupling 2 with the lock-up clutch combined. SOLUTION: A lock-up clutch control device is provided with a means detecting an operation condition of the turbocharger 62 and starts engagement of the lock-up clutch 25 before the turbocharger 62 reaches a high output condition. Engagement of the lock-up clutch 25 is performed in a short period of time without generating a connection shock, and a vehicle is accelerated smoothly after that. Change rate of rotation speed of the engine 61 or pressure in an air intake pipe 63 is detected to detect the operation condition of the turbocharger 62. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To optimize the timing of fastening of a lock-up clutch 25 at low speed running after starting so as to smoothly fasten in a vehicle power transmission combining an engine 61 equipped with a turbocharger 62 and a fluid coupling 2 with the lock-up clutch.
SOLUTION: A lock-up clutch controller disconnects a pump 21 of the fluid coupling 2 from a turbine 22 so as to start a vehicle. Then, before the speed ratio of the fluid coupling 2, that is, a rotational speed ratio of the turbine 22 to the pump 21 reaches 0.7, the controller outputs the command to start the fastening of the lock-up clutch 25. Thereby, the lock-up clutch 25 is fastened in a short time without causing a fastening shock, and the vehicle is smoothly accelerated in the engine output increasing after the operation lag of the turbocharger.
