Abstract: A method for controlling the acceleration of a hybrid transmission is provided to assist a motor output by using a generator in a driving mode of an electrical vehicle, thereby improving the motor output in initial starting, or when a driver requires rapid acceleration. An effort signal of an acceleration pedal is detected from an electro throttle control(ETC)(S1). The effort signal is analyzed, and it is determined whether or not the effort signal corresponds to a condition for rapid acceleration(S2). A charge amount of a battery is detected if the condition is satisfied(S3). A clutch is operated so that a driving mode of an electrical vehicle is maintained if the condition is not satisfied(S4). It is determined whether or not the charge amount of the battery exceeds a preset reference value(S5). The driving mode of the electrical vehicle is maintained if the charge amount of the battery does not exceed the reference value. A motor and a generator are controlled under the same power source in a release state of the clutch if the charge amount of the battery exceeds the reference value(S6). A vehicle speed is detected. It is determined whether or not the detected vehicle speed reaches a preset vehicle speed in a driving mode(S8). An engine is controlled as a main power source through the generator in the operational state of the clutch if the detected vehicle speed reaches the preset vehicle speed(S9).
