Method and system for optimizing jerking feeling of power gear shifting

The invention discloses a method and system for optimizing the jerking feeling of power gear shifting. The system comprises an electric control device, the electric control device collects an accelerator signal, a pedal signal and a gear shifting signal and then judges whether the gear shifting signal is upshift or downshift or not, if the gear shifting signal is not upshift or downshift, existing control is maintained, and if the gear shifting signal is upshift or downshift, a rotating speed adjusting signal corresponding to increasing or decreasing is generated, and the current rotating speed of an engine is obtained; the rotating speed adjusting signal is transmitted to an engine control unit, and the engine control unit adjusts the rotating speed of the engine to the target rotating speed; meanwhile, the electric control device obtains the real-time rotating speed of the engine and judges whether the real-time rotating speed of the engine is the target rotating speed or not; if the real-time rotating spee
