Automobile operation risk evaluation system and method

Abstract

The invention belongs to the automobile safety technology field and discloses an automobile operation risk evaluation system and method. The method comprises steps that a to-be-evaluated automobile model is determined, and statistics data of all the automobiles having models same as the to-be-evaluated automobile model is acquired; according to generation probability of a fault type, a harshness degree after generation of the fault type and a detection degree of the fault type, the risk priority number of a part corresponding to the fault type is determined; three evaluation indexes of each part are acquired, including the risk priority, a hazard degree and maintenance cost; entropy weights of the three evaluation indexes of each part are determined according to an entropy weight algorithm; according to the three evaluation indexes of each part and the entropy weights of the three indexes, a final risk index of the part is determined; an early warning priority of the part is determined according to the final risk index of the part; and objective and accurate automobile risk evaluation can be carried out.

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
