Abstract:
A lockup control device for a vehicle includes: a torque converter; a lockup control section configured to increase a lockup pressure difference command to an initial pressure difference when a lockup engagement condition is satisfied in a disengagement state of the lockup clutch, and then to increase the lockup pressure difference command by a ramp pressure difference by a predetermined gradient, the lockup control section being configured to determine a ramp start condition by which the lockup pressure difference command is switched from the initial pressure difference to the ramp pressure difference, based on a speed ratio which is a ratio of input and output rotation speeds of the torque converter.

Claim (Index 6):
A lockup control device for a vehicle comprising:\n a torque converter which is disposed between a driving source and a transmission, and which includes a lockup clutch, and a lockup control section configured to increase a lockup pressure difference command to an initial pressure difference when a lockup engagement condition is satisfied in a disengagement state of the lockup clutch, and then to increase the lockup pressure difference command by a ramp pressure difference by a predetermined gradient, the lockup control section being configured to determine a ramp start condition by which the lockup pressure difference command is switched from the initial pressure difference to the ramp pressure difference, based on a speed ratio which is a ratio of input and output rotation speeds of the torque converter, wherein at a reacceleration by an accelerator depression operation from an accelerator foot release coast deceleration in which the lockup clutch is disengaged, the lockup control section is configured to increase the lockup pressure difference command to the initial pressure difference, to maintain the initial pressure difference to a constant value until the lockup control section senses a speed ratio inflection point at which the speed ratio of the torque converter is shifted from a decreasing state to an increasing state, and to switch the lockup pressure difference command from the initial pressure difference to the ramp pressure difference when the lockup control section senses the speed ratio inflection point.
