CONTROL METHOD FOR EXECUTING A FLOATING FUNCTION OF A BOOM OF A WORK VEHICLE, A CORRESPONDING CONTROL SYSTEM, AND A WORK VEHICLE COMPRISING SUCH A CONTROL SYSTEM

摘要

A control method for executing a floating function of a boom (5) in a work vehicle (1), comprising the steps of: • - determining that a predetermined floating function activation command has been inputted by the operator by means of a command input means (30); • - when it is determined that the floating function activation command has been inputted by the operator: • a) acquiring, a signal or data indicative of the current position of the boom along a travel path of the boom over time, wherein the travel path include a first section between a boom full extension position and a deceleration position, a second section between the deceleration position and a grounding position, and a third section between the grounding position and a full retract position; • b) moving the boom from the current position, determined based on the signal or data indicative of the position of the boom, to the full retract position, wherein: • I) when the boom is in the first section, moving the boom according to a first rate of actuation of the boom by means of a first value of driving current; II) when the boom is in the second section, moving the boom according to a second rate of actuation of the boom, lower than said first rate of actuation of the boom, by means of a second value of driving current; III) when the boom is in the third section, moving the boom according to the force of gravity, with a null-rate of actuation of the boom by means of a third value of driving current.
