CONTROL DEVICE OF BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PURPOSE:To prevent response delay by controlling a driving pulley unit driving means till the rotational number desired value of a movable pulley and a fixed pulley accord with the calculated value. CONSTITUTION:At an input axis 14 of a belt type continuously variable transmission mechanism 13, a driving pulley unit 17 having a fixed pulley 15 and a movable pulley 16 which is capable of sliding in the axial direction is provided. CPU 36 calculates the feedback sensor desired detected value P based on the input axis rotational number detected value N1. Also, the rotational number deviation rpm is calculated from the output axis rotational number desired value N and the output axis rotational number detected value N2, and the detection corrected value P' detected by a feedback sensor 43 is calculated from the difference rpm and the feedback sensor desired detected value P. A signal is put out to a pressure regulating valve 41 by this corrected value P', and the desired rotational number is maintained.
