Description

technical field

[0001] The invention relates to the field of hybrid electric vehicle drive transmission, in particular to a hybrid electric vehicle drive system based on a planetary gear mechanism. Background technique

[0002] With the increasing global energy shortage and environmental pollution, the study of energy-saving and environmentally friendly new energy vehicles has become a current hot spot. Electric vehicles have the advantages of zero emissions, high energy utilization, simple structure, low noise and wide source of raw materials, and are one of the future development directions of the automobile industry. However, the development of traditional cars is restricted by battery technology. Because the domestic charging pile network cannot cover a large area, the battery cannot be charged in time, which limits the driving range of electric vehicles. In addition, the battery often In a state of deep discharge, during regenerative braking, the braking energy is quic...
