However, there is a certain difference between the predicted working condition and the actual working condition, so that the vehicle parts selected according to the predicted working condition are not matched with the actual working condition in the actual application. For example, if the predicted operating condition is more severe than the actual operating condition, the performance of the selected vehicle component is over-optimal, and the production cost of the vehicle component is over-high. If the actual working condition is more severe than the predicted working condition, the performance of the selected vehicle parts cannot meet the actual requirement, so that the maintenance cost of the vehicle parts in the quality guarantee period is too high. Thus, the overall cost of predicting operating conditions for a selected vehicle component is typically large.
