Problems solved by technology

[0002] Due to the inclination angle of the support plane, the frame swings, so that the support plane of the forklift does not coincide with the driving plane, and it is prone to lateral instability or even rollover due to the influence of centrifugal force during steering, causing potential safety hazards for operators and cargo
Due to the complex working environment of forklifts, especially in high-speed steering and high-lifting cargo conditions, the danger of lateral instability or even rollover is prone to occur, resulting in casualties and economic losses. Therefore, the steering safety of forklifts in the working process needs to be improved urgently.

Abstract

The invention discloses an anti-rollover control method and control system of a balanced heavy forklift, comprising the following steps: obtaining the current speed of the forklift, and determining the dynamic parameters of the first stage of the forklift; Dynamic parameters, determining the dynamic parameters of the second stage of the forklift; according to the dynamic parameters of the first stage and the dynamic parameters of the second stage, obtaining the two-stage lateral load transfer rate of the forklift; providing a preset The threshold value of the lateral load transfer rate of the forklift and the parameters of the lateral load transfer rate of the forklift are adjusted so that the current lateral load transfer rate of the forklift is within the preset threshold value of the lateral load transfer rate of the vehicle. The invention can realize the anti-rollover control method and control system of the counterweight forklift.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an anti-rollover control method and control system for a balanced heavy forklift. Background technique [0002] Due to the inclination angle of the support plane, the frame swings, so that the support plane of the forklift does not coincide with the driving plane, and it is prone to lateral instability or even rollover due to the influence of centrifugal force during steering, causing potential safety hazards for operators and cargo. Due to the complex working environment of forklifts, especially in high-speed steering and high-lifting cargo conditions, it is prone to lateral instability or even rollover, resulting in casualties and economic losses. Therefore, the steering safety of forklifts in the working process needs to be improved urgently. Contents of the invention [0003] The purpose of the present invention is to provide an anti-rollover control method and cont...
