US 8046143 B2Abstract
An ECU executes a program including: a step of detecting a turbine revolution speed, a step of detecting an engine torque TE, a step of detecting a speed change ratio, a step of setting a range an enlarged slip region when a slip region enlargement condition is satisfied, and a step of enlarging the slip region toward a lock-up region side (high-load side).
The present invention relates to a lockup clutch arranged in a hydrodynamic power transmission device such as a torque converter forming an automatic transmission, and particularly to slip control in the lockup clutch.
