The invention discloses a power acceleration control method for a series-parallel hybrid electric vehicle, which comprises the following steps of: S1, monitoring the acceleration state of a full accelerator of the vehicle so as to obtain the acceleration state data of the vehicle; s2, the maximum wheel end driving torque in the vehicle series connection mode is calculated; s3, the maximum wheel end torque of the vehicle in the parallel connection mode is calculated; s4, predicting the state of the next speed sampling point of the vehicle; and S5, state prediction is carried out on a plurality of subsequent continuous speed sampling points according to the step S4, whether series-parallel connection switching is carried out or not is comprehensively judged based on data of the sampling points, and whether the vehicle needs to adjust an acceleration strategy or not is judged by collecting various kinds of information under the vehicle running state and predicting state information of the vehicle at a plurality of subsequent collecting points. The power acceleration control method of the series-parallel configuration hybrid electric vehicle has the effect of ensuring that the power assembly system of the vehicle can exert the optimal acceleration capability.
