Title:
DRIVING FORCE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/103606
Kind Code:
A1
Abstract:
Provided is a driving force control device capable of suppressing shifting shocks when a speed ratio is stepwise changed by a continuously variable transmission. The driving force control device has the continuously variable transmission connected in a power transmittable manner to the output shaft of an internal combustion engine through a clutch so that the device can change the speed ratio of the continuously variable transmission stepwise. The driving force control device comprises a shift deciding means (Step S1) for deciding whether or not the torque capacity of the clutch is relatively high and whether or not the speed ratio of the continuously variable transmission is stepwise changed while the vehicle is running, and a first shifting means (Step S3) for lowering the torque capacity of the clutch, when the speed ratio of the continuously variable transmission is stepwise changed, before the speed ratio is changed by the continuously variable transmission, synchronizing the rotating speed of the internal combustion engine, while the speed ratio is being changed by the continuously variable transmission, with the input rotating speed after the speed ratio is changed by the continuously variable transmission, and raising the torque capacity of the clutch after the speed ratio is changed by the continuously variable transmission.
