Problems solved by technology

The energy consumed when the boom is raised and lowered not only makes the engineering vehicle at a higher energy consumption level, but also increases the heat dissipation load of the hydraulic system of the engineering vehicle.
If only the same boom speed is used under loading conditions, it will affect the loading performance and the smoothness and comfort of the driver's operation to a certain extent

Abstract

The invention discloses an engineering vehicle and a movable arm control method and device of the engineering vehicle. The movable arm control method of the engineering vehicle comprises the steps that the displacement of a movable arm oil cylinder under the current working condition is obtained; the height of a movable arm under the current working condition is determined according to the displacement of the movable arm oil cylinder; the flow of hydraulic oil in the movable arm is determined according to the height of the movable arm. Therefore, the speed of the movable arm can be self-adaptively adjusted according to the change of the height of the movable arm, and the loading performance of transshipment equipment and the operation smoothness and comfort of a driver are improved. For example, when the height of the movable arm is large, namely the lifting distance of the movable arm is long, the speed of the movable arm can be increased by increasing the flow of the hydraulic oil in the movable arm so that the loading efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent engineering vehicles, in particular to an engineering vehicle, a method and a device for controlling a boom of an engineering vehicle. Background technique [0002] There are many working conditions in the loading operation of engineering vehicles, such as loading on flat ground, loading on platforms, and digging deep trenches. Different loading conditions have different requirements for the loading height. For example, under some loading conditions, the lifting distance of the boom is short, and under some loading conditions, the lifting distance of the boom is long. The energy consumed when the boom is raised and lowered not only makes the engineering vehicle at a higher energy consumption level, but also increases the heat dissipation load of the hydraulic system of the engineering vehicle. If only the same boom speed is used under loading conditions, it will affect the loading performance...
