Abstract

See full text

A vehicle lock-up clutch control device is provided to suppress engine racing when a lock-up clutch is engaged at the time a vehicle starts moving. The vehicle lock-up clutch control device is provided with a control unit that delays the rise in lock-up command pressure if a line pressure, which is the source pressure of the actual lock-up oil pressure, is rising when the lock-up clutch is engaged at the time the vehicle starts moving. The control unit executes a torque reduction in the engine at least during the delay in the lock-up command pressure.
