Title:
CONTROL DEVICE AND CONTROL METHOD FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/054229
Kind Code:
A1
Abstract:
In order to perform feedback control of the transmission ratio, a transmission controller (12) for a continuously variable transmission (4) is provided with: a target value generation unit (131); advance compensators (136, 137) for performing phase advance compensation; delay compensators (145, 146) for performing phase delay compensation; and a phase compensation on/off determination unit (133) which determines the on/off states of the advance compensation and the delay compensation. A first peak value frequency determination unit (141) reduces the peak value frequency of the phase advance compensation as the transmission ratio of the transmission (4) increases. A second peak value frequency determination unit (144) reduces the peak value frequency of the phase advance compensation as the peak value frequency of the phase advance compensation reduces.
