Title:
VEHICLE LOCKUP CLUTCH CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/031050
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vehicle lockup clutch control device that suppresses engine racing when a lockup clutch is engaged at the time a vehicle starts moving. A torque converter (4) having a lockup clutch (3) is provided between an engine (1) and a continuously variable transmission (6). A vehicle is provided with an initial-motion lockup control means that, if the line pressure, which is the source pressure of the actual lockup oil pressure, is rising when the lockup clutch (3) is engaged at the time the vehicle starts moving, delays the rise in lockup instruction pressure. The initial-motion lockup control means implements a torque reduction in the engine (1) at least during the delay in lockup instruction pressure.
