Problems solved by technology

[0002] At present, when the driver performs the lifting operation of the dump truck container, due to the influence of the environment, perception and other factors, he cannot intuitively understand the stability of the vehicle, nor can he make a correct analysis and judgment on the safety of the entire lifting process of the vehicle , it is easy to cause the hydraulic cylinder of the vehicle to be pulled out, which not only reduces the service life of the hydraulic cylinder, causes the carriage to overturn excessively, and even causes the entire vehicle to overturn, causing major personnel and property losses

Abstract

The invention discloses a control method and a control system for preventing backward tipping of a dump truck bed. The control method for preventing backward tipping of the dump truck bed comprises the steps of calculating a front axle loading rate of a dump truck and difference between a lifting moment of a hydraulic cylinder and a rotating moment of the truck bed; when the front axle loading rate does not exceed a first threshold and the difference between the lifting moment of the hydraulic cylinder and the rotating moment of the truck bed does not exceed a second threshold, enabling an alarm to give an alarm and enabling a display device to prompt a danger character; and when the front axle loading rate does not exceed the first threshold and the difference between the lifting moment of the hydraulic cylinder and the rotating moment of the truck bed exceeds the second threshold, forbidding the dump truck to lift. According to the control method and the control system for preventingbackward tipping of the dump truck bed, a risk that the hydraulic cylinder is drawn out during the lifting operation of the dump truck and a risk that the truck bed is excessively tilted backwards can be reduced, the service life of the hydraulic cylinder can be prolonged, and the safeties of the truck and a driver can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of dump trucks, and in particular relates to a control method and a control system for preventing backturning of a dump truck box. Background technique [0002] At present, when the driver performs the lifting operation of the dump truck container, due to the influence of the environment, perception and other factors, he cannot intuitively understand the stability of the vehicle, nor can he make a correct analysis and judgment on the safety of the entire lifting process of the vehicle , It is easy to cause the hydraulic cylinder of the vehicle to be pulled out, which not only reduces the service life of the hydraulic cylinder, causes the carriage to overturn excessively, and even causes the entire vehicle to overturn, causing significant personnel and property losses. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art field, the object o...
