Abstract
Official abstract text for this publication.
A control device for a lockup clutch of a vehicle. A slip control device executes slip control to make a rotational speed difference between the input member and the input shaft match a target slip speed according to a state of the vehicle by half engagement of the lockup clutch. A clutch temperature obtaining means obtains a clutch temperature of the lockup clutch. A determining means determines if the lockup clutch should be fully engaged or disengaged based on at least a state of the motor if the clutch temperature becomes equal to or higher than a predetermined temperature during execution of the slip control. A slip control stop means for stopping the slip control by fully engaging or disengaging the lockup clutch according to the determination result of the determining means.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for a lockup clutch capable of coupling an input member connected to a motor of a vehicle and an input shaft of a transmission device and decoupling the input member and the input shaft, comprising: slip control means for executing slip control to make a rotational speed difference between the input member and the input shaft match a target slip speed according to a state of the vehicle by half engagement of the lockup clutch; clutch…
