Clustering analysis-based double-semi-dragging vehicle driving stability automatic identification and warning system

Abstract

The invention relates to a clustering analysis-based double-semi-dragging vehicle driving stability automatic identification and warning system. The clustering analysis-based double-semi-dragging vehicle driving stability automatic identification and warning system comprises a test data collecting module, a data pre-treatment module, an off-line clustering analysis module, an online identification module, a vehicle real-time data collecting module and a decision executing module. The output end of the test data collecting module is connected to the input end of the off-line clustering analysis module through a test data pre-treatment module; one output end of the off-line clustering analysis module is connected with the input end of the online identification module, and the other output end of the off-line clustering analysis module is connected with the decision executing module; the output end of the vehicle real-time data collecting module is connected with the input end of the online identification module through a real-time data pre-treatment module, and the output end of the online identification module is connected with the input end of the decision executing module. The clustering analysis-based double-semi-dragging vehicle driving stability automatic identification and warning system performs off-line clustering analysis on pre-treated collected test data, achieves classification of vehicle driving states through K-Means clustering analysis and then takes corresponding safety measures according to classification results.

Description

technical field [0001] The invention belongs to the technical field of driving safety of automobiles and trains, and relates to an automatic identification and early warning system for the driving stability of double semi-trailers based on cluster analysis. Background technique [0002] The double-semi-trailer car train is composed of a tractor and two semi-trailers. During the driving process of the car, on the one hand, the car-train transport has high productivity, large load capacity, and high quality utilization coefficient. The manufacturing cost of the trailer is low and the engine fuel consumption rate is low. Low cost, easy maintenance, suitable for long-distance transportation, and can conveniently realize section transportation, drop-and-hook transportation, and roll-on-roll transportation. On the other hand, with the globalization of economy and trade, the frequent transportation of goods between regions has increased the demand for long-distance transport vehicl...

AI Technical Summary

Problems solved by technology

The defects of this patented technology are: 1. High requirements and strong dependence on road marking lines. If the traffic marking lines disappear, the system will not work. 2. Only rely on the lateral swing parameters between the tractor and trailer to judge There is little basis for the lateral running stability of the train, and the reliability is poor
