Title:
COORDINATION CONTROL DEVICE FOR POWER SOURCE AND CONTINUOUSLY VARIABLE TRANSMISSION FOR VEHICLE
Document Type and Number:
Japanese Patent JP3885766
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of preventing a shock and a sense of incongruity due to an output change of a power source corresponding to slippage or the like of a continuously variable transmission.
SOLUTION: In a coordination control device for the power source and the continuously variable transmission for a vehicle, the continuously variable transmission is connected to an output side of the power source generating driving force for traveling, holding pressure setting a torque capacity of the continuously variable transmission based on satisfaction of slippage determination in the continuously variable transmission is increased, and input torque to the continuously variable transmission is reduced. A holding pressure/input torque order control means (steps S60, S90, S110) is provided to control so that actual pressure of the holding pressure is increased at or after the satisfaction of convergence determination of the slippage, and afterwards restoration of actual torque of the reduced input torque is completed. Accordingly generation of re-slippage in the continuously variable transmission and the sense of incongruity due to increase in fluctuation of input shaft torque can be prevented or restrained.
