The invention discloses a series-parallel hybrid power vehicle energy management method based on a double-layer optimization framework. The method comprises the following steps: determining working modes of a vehicle power system, wherein the working modes comprise a pure electric mode, a series mode, a parallel economic mode, a parallel power mode and an engine direct drive mode; performing mode switching according to the working mode switching threshold value; optimizing the working mode switching threshold value by taking optimal fuel economy and emission performance as a target to obtain an optimal working mode switching threshold value; performing reverse solution on energy distribution of the generalized series connection mode and the generalized parallel connection mode by adopting dynamic programming, and performing forward optimization according to the working mode of the power system to obtain an energy distribution result; the generalized series mode comprises a pure electric mode and a series mode; the generalized parallel mode comprises a parallel economic mode, a parallel power mode and an engine direct drive mode; and working mode switching is carried out according to the optimal working mode switching threshold value, and energy distribution is carried out according to an energy distribution result corresponding to the optimal working mode switching threshold value.
