The invention provides an acceleration control method for a plug-in hybrid electric vehicle, relates to the field of whole vehicle electric control system control, and aims to monitor not only the opening degree of an accelerator pedal but also the starting rate of the accelerator pedal when working condition parameters of the vehicle meet preset working conditions so as to judge whether a driver has a rapid acceleration request or not. When it is monitored that the starting speed of the accelerator pedal is large, it is indicated that a driver has an urgent acceleration request, at the moment, the corresponding relation between the opening degree of the accelerator pedal and the output torque is updated, and the gain torque relation table is used for replacing the original torque relation table; the output torque corresponding to the same accelerator pedal opening degree in the gain torque relation table is larger than the output torque in the original torque relation table. And finally, the motor output tor
