Anti-rollover early warning system for heavy trucks on curves

Abstract

A heavy truck curve anti-rollover early warning system, the method of the present invention includes the following steps: 1) setting a heavy truck curve anti-rollover early warning system based on dynamic monitoring, which includes: measuring device, early warning device, man-machine cooperation device and cloud computing connected device. 2) Use the camera to capture information such as road slope width and obstacles around the vehicle, and combine the vehicle roll angle measured by the inclinometer, the curvature of the curve and the height of the center of mass measured by the cloud to calculate the vehicle roll acceleration, and estimate the roll warning time and side Leaning towards neighboring vehicles affects the result. 3) Judging the warning level according to the offset distance of the center of mass, the wheel camber and the cabin tilt angle, the warning device works, and the early warning response plan under the human-machine synergy is adopted in combination with the cloud computing results. Compared with the prior art, the invention can more safely solve the problem of keeping a heavy truck moving forward at a high speed on a curve and preventing rollover.

Description

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

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
