Title:
CONTROLLER OF CONTINUOUSLY VARIABLE TRANSMISSION AND CONTROL METHOD OF CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2017166615
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a controller and control method of a continuously variable transmission, capable of improving reduction of a vibration prevention effect due to advance compensation according to change of a resonance frequency of a power train.SOLUTION: A controller 12 is a controller of a continuously variable transmission configured to perform feedback shift control of a transmission so that an actual transmission ratio Ratio_A becomes a target transmission ratio Ratio_D. The controller 12 includes a first phase advance compensator 136 and a second phase advance compensator 137 configured to perform phase advance compensation of feedback primary instruction pressure Ppri_FB, and a peak value frequency determination unit 141 configured to change a peak value frequency Fpk according to the transmission ratio Ratio_D.SELECTED DRAWING: Figure 4
