Active transport vehicle rollover prevention system on basis of air suspensions adjustment

Abstract

The invention provides an active transport vehicle rollover prevention system on the basis of air suspension adjustment, belongs to the technical field of active transport vehicle safety control and particularly relates to active rollover prevention control technologies for road transport vehicles which are mainly applied to passenger transport and freight transport. The active transport vehicle rollover prevention system comprises an air compressor, vehicle body height sensors, air suspensions, vehicle body height control electromagnetic valves, an air treatment device and the like. The active transport vehicle rollover prevention system has the advantages that whether a running transport vehicle is under rollover hazardous conditions or not is preliminarily judged by the control system and accordingly can be prevented from being suddenly rolled over; acceleration signals, steering wheel angle signals, vehicle body height signals and vehicle speed signals of the transport vehicle are acquired by the various sensors of the control system, the signals acquired from the vehicle in current states are converted, computed, analyzed and judged, the air compressor, the vehicle body height control electromagnetic valves and exhaust valves are controlled, accordingly, the heights of two sides of a frame can be adjusted, the transport vehicle can be prevented from being suddenly rolled over in running procedures, and the running safety of the transport vehicle can be improved.

Description

technical field [0001] The invention relates to the field of active safety control of transport vehicles, in particular to an active anti-rollover control system for transport vehicles based on air suspension adjustment. . Background technique [0002] In recent years, with the rapid development of China's transportation industry, the active safety control technology of passenger and freight-based road transport vehicles is relatively lacking. Most transport vehicles are only equipped with a set of ABS safety systems, and the center of mass of transport vehicles is high, the body is long, and the high-speed Rollover is more likely to occur while driving. Once a rollover accident occurs, it will cause serious casualties and property losses; when a high-speed transport vehicle turns, it will generate centrifugal force, which will cause the center of gravity of the transport vehicle to shift, resulting in pressure on one side of the transport vehicle. As the pressure rises, t...

[0002] In recent years, with the rapid development of China's transportation industry, the active safety control technology of passenger and freight-based road transport vehicles is relatively lacking. Most transport vehicles are only equipped with a set of ABS safety systems, and the center of mass of transport vehicles is high, the body is long, and the high-speed Rollover is more likely to occur while driving. Once a rollover accident occurs, it will cause serious casualties and property losses; when a high-speed transport vehicle turns, it will generate centrifugal force, which will cause the center of gravity of the transport vehicle to shift, resulting in pressure on one side of the transport vehicle. As the pressure rises, the pressure on the other side decreases. The increase in the pressure on one side of the suspension leads to an increase in deformation, and the decrease in the pressure on the suspension on the other side reduces the deformation, which makes one side of the transport vehicle rise and the other side lower. , causing the tendency of the transport vehicle to roll over; when the transport vehicle makes a sharp turn to avoid the emergency situation ahead, the possibility of the transport vehicle rolling over increases, which is most likely to cause casualties and property losses; the existing transport vehicle air suspension The system is mainly used for vibration reduction during vehicle driving, and does not have the function of anti-rollover control
