Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to a control system and a control method for a dual-motor automatic transmission of a pure electric vehicle. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, pure electric vehicles, as energy-saving and environment-friendly vehicles, have received more and more attention from the government and enterprises. And with the rapid development of automotive electronics, automotive intelligence is the general trend. Although the electric vehicle manual transmission has a simple structure and low cost, it has the problems of inconvenient operation, low maximum speed, and insufficient power for climbing, especially for starting on a hill. Contents of the invention [0003] The purpose of the present invention is to provide a pure electric vehicle dual-motor automatic transmission control system and its control meth...
