Title:

METHOD OF SELECTING AUTOMATIC OPERATION MODE OF WORKING MACHINE

Document Type and Number:

WIPO Patent Application WO/1993/009300

Kind Code:

A1

Abstract:

Even when a bucket is changed to an optional special bucket, a path control as intended by an operator can be automatically performed without making correction for the nose angle of the original bucket. For this purpose, in an operation mode determining section (9), there is calculated the possibility (U2) of an operation mode being a nose fixing mode depending on how much a bucket attitude angle ($g(g)) is deviated from a predetermined angle, and there is also calculated the possibility (U1) of an operation mode being a mode for fixing an angle to the ground depending on a magnitude of a value for computing an allowable angle held with respect to the ground, whereby an operation mode during the automatic path control can be automatically determined through the comparation between these two possibilities (U1, U2).
