Title:
ZERO-CORRECTING DEVICE FOR SENSOR OF WORKING MACHINE
Document Type and Number:
Japanese Patent JP3797881
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a rolling control having a good response and accuracy by using a tilting sensor and an angular velocity sensor by performing the zero correction of the angular velocity sensor even on an always moving tractor.
SOLUTION: This rolling-control means 24 of a plowing unit 4 on a tractor, based on a tilting sensor 15 and an inexpensive angular velocity sensor 23 is provided by installing a memorizing means 25 for memorizing a plurality of sampling outputted values detected by the angular velocity sensor 23, a zero-controlling means 26 for performing a calculating treatment of the plurality of memorized sampling outputted values for setting their mean value as zero, a judging means H for judging the high or low of the posture stability of a machine body 21, and a correcting means 28 at the controlling device 22 for actuating the zero-controlling means 26 when the posture stability of the machine body 21 is high and not actuating the zero-controlling means 26 when the posture stability of the machine body 21 is low.
