Hydrostatic transmission vehicle and hydrostatic transmission controller

摘要

A hydrostatic transmission vehicle comprises: a fuel adjustment position detection portion ( 681 ) which detects an operation position of a fuel adjustment portion ( 68 ); a deceleration operation position detection portion ( 691 ) which detects an operation quantity of a deceleration operation portion ( 69 ); and a controller ( 9 ) which controls a displacement of a hydrostatic transmission ( 7 ), and the controller ( 9 ) comprises: an operation state judgment portion ( 91 ) which judges operation states of the fuel adjustment portion ( 68 ) and the deceleration operation portion ( 69 ) based on detection values acquired by the fuel adjustment position detection portion ( 681 ) and the deceleration operation position detection portion ( 691 ); and a displacement control command generation portion ( 94 ) which generates a displacement control command which differs depending on a case where an engine revolution number is restricted by the fuel adjustment portion ( 68 ) and a case where an engine revolution number is restricted by the deceleration operation portion ( 69 ).
