Method, device and equipment for evaluating reliability performance of whole vehicle and medium

Abstract

The invention discloses a vehicle reliability performance evaluation method, device and equipment and a medium. The method comprises the following steps: acquiring historical test data of a to-be-evaluated vehicle type; according to the historical test data, determining a reliability test scheme of the to-be-evaluated vehicle type in the current test stage; according to the reliability test scheme, performing a whole vehicle reliability test of the current test stage on the to-be-evaluated vehicle model to obtain reliability test data of the current test stage; and according to the reliability test data and the acquired reliability target data, determining a reliability level assessment result of the to-be-assessed vehicle type. According to the application, the whole vehicle reliability performance verification of the vehicle is directly associated with the vehicle market reliability index, so that the reliability performance achievement risk of the vehicle is evaluated during the test, and the market reliability level estimation after the whole vehicle reliability test of the vehicle is completed is realized; therefore, the reliability performance verification of the whole automobile is matched with the market user to use to the maximum extent, and the maximum economic benefit of the verification cost is realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an evaluation method, device, equipment and medium for the reliability performance of a complete vehicle. Background technique [0002] As one of the most important performances of a car, the reliability of the car has been widely valued by OEMs and market users. During the research and development stage of the car, a large number of vehicle reliability tests will be done to test the reliability level of the car. The reliability test of the whole vehicle will cost the OEM a lot of manpower, material resources and financial resources. [0003] The current automobile reliability test scheme design mainly relies on the development experience of the main engine factory itself, and the correlation with the feedback from the actual vehicle used by the market users is not strong. In the automobile reliability test, it is impossible to evaluate the performance of the automobile afte...
