Title:
ENGINE LOAD CONTROL DEVICE FOR AUTOMATIC TRAVELING TYPE WORKING MACHINE
Document Type and Number:
Japanese Patent JP3516303
Kind Code:
B2
Abstract:
PURPOSE: To attain the improvement of engine load control responsiveness and the prevention of hunting simultaneously.
CONSTITUTION: The detected rotating speed of an engine speed sensor 33 is read every specified time (S1), and the deviation E with the appropriate rotating speed and the elapsed change ΔS of the detected rotating speed are computed from the detected rotating speed (S2). The adjustment quantity HB1 of an HST lever for adjusting the change gear ratio of an HST 5, and the adjustment quantity HB2 of a throttle are respectively determined by fuzzy control rules from the computed deviation E and the computed change ΔS (S3). The HST lever and throttle opening are then adjusted on the basis of the determined adjustment quantity HB1, HB2.
