Title:
SPEED CHANGE CONTROL FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JPS63284041
Kind Code:
A
Abstract:
PURPOSE:To improve the following performance to an aimed value by adding the output of a means for determining the fundamental operation quantity according to the operation signal, into the output of a PID (proportional, integration, differential) operation means for correcting the deviation for the aimed value such as engine revolution speed, etc. CONSTITUTION:The PID operation means is constituted of a proportional means 10 having a gain Kp, differentiation means 11 having a gain Kd, and an integeration means 12 having a gain Ki. Each output signal of the PID operation means is added and input into an operation part 5, and the operation means 5 outputs the operation quantity corresponding to the input signal into a continuously variable transmission 3. Then, the deviation between the control quantity and the aimed quantity is input into the PID operation means, and the deviation is corrected. In this case, a means 13 for determining the standard operation quantity corresponding to a prescribed operation signal is installed. The output of the standard operation quantity determining means 13 is added with the output of the PID operation means, and input into the operation part 5 of the continuously variable transmission 3. Therefore, speed change is started before a deviation is generated between the control quantity and the aimed value.
