AMT gear shifting optimization control system and method based on vehicle VCU architecture

The invention relates to an AMT gear shifting optimization control system and method based on a whole vehicle VCU framework. The AMT gear shifting optimization control system comprises a whole vehicle control system, a transmission control system, an engine control system, an electronic braking system, an automatic emergency braking system and a gear shifting control system. The transmission control system, the electronic braking system, the gear shifting control system and the automatic emergency braking system are electrically connected with the GW gateway through a PCAN bus. The whole vehicle control system and the engine control system are electrically connected with the GW gateway through an ECAN bus. The PCAN bus is electrically connected with the ECAN bus through a whole vehicle control system; a transmission control system judges whether to execute a jump gear strategy by judging an accelerator and a whole vehicle acceleration signal, if yes, an engine is called for braking in the jump gear and upshif
