Heavy truck curve anti-rollover early warning system

Abstract

The invention discloses a heavy truck curve anti-rollover early warning system, and the method comprises the following steps: 1) setting the heavy truck curve anti-rollover early warning system basedon dynamic monitoring, wherein the system comprises a measurement device, an early warning device, a man-machine cooperation device, and a cloud computing connection device; and 2) capturing information such as road gradient and width and obstacles around the vehicle by using a camera, calculating vehicle roll acceleration by combining a carriage roll angle measured by an inclinometer and curve curvature and centroid height measured by a cloud end, and speculating roll early warning time and an influence result of roll on adjacent vehicles; and 3) judging an early warning level according to the centroid offset distance, the wheel camber angle and the carriage inclination angle, enabling the early warning device to act, and combining a cloud computing result to adopt an early warning response scheme under a man-machine synergistic effect. Compared with the prior art, the system can more safely solve the problems of keeping the heavy truck advancing at a high speed and preventing the heavy truck from rolling sideways on a curve lane.

Description

technical field [0001] The invention relates to a heavy truck safety monitoring device, in particular to a heavy truck curve anti-rollover early warning device based on dynamic detection. Background technique [0002] With the progress and development of society, the demand for load and speed of heavy-duty trucks is increasing. However, due to its high center of mass position, large mass and volume, rollover accidents are prone to occur when turning at high speeds and when road curvature is small. Rollover is a highly frequent and dangerous traffic accident, and it has a higher casualty rate than other forms of traffic accidents. According to the statistical report of the National Highway Traffic Safety Administration, the increase in the number of deaths caused by rollovers was significantly higher than that of collisions. In addition, while passenger car rollover accidents decreased, heavy truck fatal rollover accidents increased significantly. Vehicle rollover is divided...

AI Technical Summary

Problems solved by technology

Therefore, there are the following main problems in the current detection and early warning methods: first, the vehicle load changes and it is not convenient to measure the height of the center of mass when driving at high speed; second, the load transfer rate measured on a steep road surface has a large error with the actual situation , cannot be used as the basis for early warning data, so it cannot guarantee the safe high-speed driving of heavy trucks on curves
