A system and method for evaluating vehicle operation risk

Abstract

The invention belongs to the technical field of automobile safety, and discloses a system and method for evaluating the running risk of automobiles. The probability of occurrence of the fault type, the severity of the fault type after occurrence, and the detection degree of the fault type, determine the risk priority number of the component corresponding to the fault type; thus obtain three evaluation indicators for each component: risk priority number, The degree of hazard and maintenance cost; the entropy weight of the three evaluation indexes of each component is determined according to the entropy weight method; the entropy weight of the component is determined according to the three evaluation indexes of each component and the entropy weight of the three evaluation indexes. The final risk index; according to the final risk index of the component, the priority of early warning of the component is determined; an objective and accurate risk evaluation can be performed on the automobile.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to an evaluation system and method for automobile operation risks. Background technique [0002] In recent years, the number of motor vehicles in my country has grown rapidly. At the same time, road traffic accidents occur frequently, causing serious damage to people's lives and properties. With the development of economy and society, people's safety awareness has been enhanced, and higher requirements have been put forward for the safety of automobile operation, especially the cognition and early warning of automobile operation risks are urgently needed. [0003] At present, automobile safety evaluation mainly focuses on the subjective evaluation or detection evaluation of some performance and indicators of automobiles, such as the evaluation of braking system, steering system, safety auxiliary facilities, etc. For example, Huang Yonghe and Pan Jianliang of Ch...

Problems solved by technology

[0004] However, judging from the current technical situation of the industry, the safety technology evaluation of automobiles is mainly realized through the performance detection and subjective evaluation of various technical conditions of automobiles. It lacks the dynamic cognition of automobile operating conditions, that is, it cannot Real-time evaluation of the safety performance of the vehicle based on the vehicle's operating conditions, such as driving mileage, maintenance and other factors closely related to the safety of the vehicle's operation
