Comprehensive early warning decision-making method for passenger car safety based on typical dangerous working conditions

Abstract

The invention discloses a comprehensive early warning decision-making method for operating passenger cars based on typical dangerous working conditions, including: 1) determining the indicators of typical dangerous working conditions, and establishing a matrix model S of early warning indicators; 2) selecting causal monitoring parameters, and building a monitoring matrix model R , the specific monitoring parameter value, to obtain the specific monitoring matrix Ri; 3) establish a weight matrix model K, S=RK according to the monitoring parameter value, establish a specific weight matrix Ki; 4) compare the specific monitoring matrix Ri with the weight matrix Ki 5) According to the size of the matrix Si, determine which working condition the current danger is mainly caused by. The larger the value, the more serious the danger. This method takes large commercial passenger cars as the research object, selects typical dangerous working conditions, selects typical monitoring parameters, establishes weights, and multiplies the real-time monitoring variable matrix with the weight matrix to obtain the real-time driving condition matrix. Select the corresponding dangerous working conditions for early warning, so as to achieve the effect of early warning.

Description

technical field [0001] The invention relates to vehicle safety early warning technology, in particular to a comprehensive early warning decision-making method for operating passenger cars based on typical dangerous working conditions. Background technique [0002] With the rapid development of highway traffic and the growth of car ownership, road traffic accidents have increased sharply, and the traffic safety situation has become increasingly severe. Statistics from the United Nations show that more than 1.2 million people die in traffic accidents all over the world every year, and millions of people are injured, and the number of traffic accident deaths in my country ranks first in the world for more than 10 consecutive years, especially the special and serious cases of mass deaths and injuries. Traffic accidents occur frequently. Statistics on vehicle traffic accidents show that, in 2009, serious traffic accidents caused by operating passenger vehicles that resulted in th...

Problems solved by technology

Most of the existing vehicle safety early warning technologies are researched on a single dangerous working condition, and the coupling effect between various operating parameters and typical dangerous states of the vehicle is not comprehensively considered for comprehensive early warning decision-making.
