Abstract

The present invention provides a method for predicting the remaining life of an on-board electronic system with a high degree of algorithm optimization and accurate prediction results, including the following steps B1. During the operation of the on-board electronic system, the load conditions and evaluation index data are collected in real time through sensors and stored in the host computer Memory; B2. Determine the critical value M0 of the evaluation index; B3. Resample the load condition and evaluation index every time Δt to obtain the current value Mj of the evaluation index, and calculate the current degradation rate vj of the evaluation index; B4. According to B2. The critical value of the evaluation index M0 in and B3. The current value of the evaluation index Mj and the degradation rate vj in B3. Calculate the remaining life Lj at each moment; B5. Calculate the activation energy change Pm; B6. When the activation energy change Pm has an inflection point and is the minimum When the value is set, the corresponding predicted lifetime is displayed and notified to the user.

Description

technical field [0001] The invention relates to the technical field of electronic system evaluation, in particular to a method for predicting the remaining life of a vehicle electronic system.
