Title:
CONTROL DEVICE FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3339367
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To set a line pressure to a proper value by detecting an output by an internal combustion engine rotation state detection means and an internal combustion engine output detection means, while detecting the input load change amount to a continuously variable transmission by a rotation change state detection means and an input load change amount detection means and outputting an order signal to the pressure adjust valve for the continuously variable transmission by a working fluid pressure control means.
SOLUTION: An engine rotation sensor 301 is installed on the output shaft 10a of an engine 10 as the rotation state detection means of an internal combustion engine and the rotation change state detection means of a drive system and the input number of 4 rotation sensor 305 is installed on a turbine output shaft 13 as a drive system rotation change state detection means. A transmission control unit 300 is provided with a micro computer 310. The output of a pulse control signal SS/M in response to a real speed change ratio, the output of a line pressure control signal SPL, the output of a lock up control signal SL/U and a clutch tightening control signal SCL in response to a clutch pressure control duty ratio D/TCL are outputted.
