Embodiment Construction

[0044] In the prior art, the user usually only knows that a component in the vehicle has been damaged when the vehicle is overhauled or maintained, or when the vehicle breaks down. In other cases, the user cannot know the failure probability of a certain component in the vehicle in time.

[0045] In order to solve the above problems, in the embodiment of the present invention, according to the collected driving behavior data in the vehicle within the preset first time period, the trained component wear model is used, and according to each component wear model in the component wear model, The first mapping relationship between the driving behavior and the wear degree obtains the wear degree of the parts within the preset first time period, and according to the second mapping relationship between the failure probability of the parts and the wear degree of the parts, Get the failure probability of the component. Different driving behaviors affect the wear rate of vehicle parts, ...

Abstract

Disclosed are a method, a device and a system for vehicle part fault probability estimation. The method includes acquiring driving behavior data of vehicle within a first duration preset, processing the driving behavior data within the first duration, inputting the processed driving behavior data to a part wear model has been trained, calculating the corresponding fault probability of parts at the end of the first duration according to the part wear model, and then outputting the fault probability. Input parameter of the part wear model includes driving behavior; the middle parameter refers to wear degree, the output parameter refers to the fault probability of the parts; the wear degree and the driving behavior are of first mapping relation, and the fault probability of the parts and the wear degree of the parts are of a second mapping relation. According to the scheme, by the method, the device and the system, the fault probability of vehicle parts can be acquired in time so as to improve driving safety.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a method, device and system for estimating the probability of failure of vehicle parts. Background technique [0002] With the improvement of people's living standards, more and more families own cars. As an important means of transportation, automobiles play an increasingly important role in people's lives. With the passage of time and continuous use, its various parts will show different degrees of wear and tear. [0003] Usually, the user can know the wear and tear of each component only when the vehicle is overhauled or maintained in a 4S shop, and then the probability of failure of the vehicle’s components can be estimated. For users who do not regularly overhaul or maintain the vehicle, only when the vehicle breaks down do they know that the parts in the vehicle have been damaged. [0004] In the prior art, it is difficult for users to know the failure probability ...
