An Adaptive Trend Index-Driven Remaining Useful Life Prediction Method for Renewable Energy Vehicle Reducers

Algorithm 2

Remaining useful life prediction.

	Input: All trend index (TI).
(1)	For i = t:10: T.
(2)	Carry out the initial value fitting of the parameters through TI [1: t].
(3)	while
(4)
(5)	Importance sampling
(6)	Weight update
(7)	Resampling
(8)	State estimation
(9)	End.
(10)	Calculate the residual life according to formula (8).
(11)	End.
	Output: Prediction results distribution of residual life.
