Anti-rollover control method and control system for balanced heavy forklift

Abstract

The invention discloses an anti-rollover control method and control system for a balanced heavy forklift. The method comprises the following steps: obtaining the current speed of a forklift, and determining the dynamic parameters of the first stage of the forklift; determining dynamic parameters of the second stage of the forklift according to the dynamic parameters of the first 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 transverse load transfer rate of the forklift; and providing a preset transverse load transfer rate threshold value of the forklift and adjusting transverse load transfer rate parameters of the forklift to enable the current transverse load transfer rate of the forklift to be within the preset transverse load transfer rate threshold value of the vehicle. The control method and control system can prevent rollover of a balanced heavy forklift.

Description

Technical field[0001]The invention relates to the technical field of vehicle control, in particular to a rollover prevention control method and control system for a balanced heavy forklift.Background technique[0002]Due to the inclination of the support plane, the frame swings, so that the forklift's support plane does not coincide with the driving plane, and it is prone to lateral instability or even rollover under the influence of centrifugal force when turning, causing hidden dangers to the safety of operators and cargo. Due to the complex working environment of forklifts, especially in high-speed steering and high-lifting conditions, the risk of lateral instability or even rollover is likely to occur, causing casualties and economic losses. Therefore, the steering safety of forklifts needs to be improved during the working process.Summary of the invention[0003]The purpose of the present invention is to provide a counterbalanced heavy forklift anti-rollover control method and cont...

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.
