摘要： A lubricating oil supply control device controls a lubricating oil supply amount to a transmission in a construction machine including a torque converter with a lock-up clutch. The lubricating oil supply control device includes a clutch state determining section, a lubricating oil amount detecting section and a lock-up clutch controlling section. The clutch state determining section determines whether or not the lock-up clutch is being coupled. The lubricating oil amount detecting section detects whether or not the lubricating oil supply amount to the transmission is short of a preliminarily set supply amount. The lock-up clutch controlling section decouples the lock-up clutch when the lock-up clutch is being coupled and the lubricating oil supply amount is short of the preliminarily set supply amount.

摘要： In a work vehicle, a control unit is configured to control a lock-up hydraulic pressure for controlling switching of a lock-up clutch. The control unit is configured to execute a lock-up slippage control for switching the lock-up clutch into a slippage state when the work vehicle starts moving. The control unit is configured to control the lock-up hydraulic pressure based on work instrument load information, pertaining to a load of a work instrument during execution of the lock-up slippage control.
