Engine active throttle shovel control method and loader

Abstract

The invention relates to a loader, in order to solve the problem that the engine accelerator needs to be manually controlled during the shoveling operation of the existing loader; it provides an engine active throttle shovel control method and a loader, wherein the control method is to select and set through the accelerator gear knob The default speed value of the engine during shovel operation; during the forward process, the control unit controls the engine to run at the default speed value and obtains the accelerator pedal stroke and brake pedal stroke; when the engine speed value corresponding to the accelerator pedal stroke is greater than the default speed value Control the engine speed to increase with the accelerator pedal, but not to decrease with the release of the accelerator pedal, and control the engine to maintain the current speed, the default speed or the idle speed according to the stroke of the brake pedal. In the present invention, the active throttle control is adopted, so that the engine control is more accurate, and the labor intensity of the driver is reduced at the same time.

Description

technical field [0001] The present invention relates to a loader, more particularly, to an engine active throttle shovel control method and a loader. Background technique [0002] A loader is a widely used earth-moving machine, mainly used for short-distance transfer of materials. When the loader is working, the action of the working device and the accelerator during the shovel loading process are very important, which can directly affect the working efficiency of the loader shovel and the fuel consumption of the machine. Material shovel loading refers to the action of closing the bucket after the bucket is inserted into the pile and the lifting action of the boom that cooperates with the action of closing the bucket. [0003] As we all know, when the loader driver operates the loader for shoveling operations, he needs to operate the control handles of the bucket and boom several times to complete a shovel operation. The operation requires high technical level of the drive...
