Description

technical field [0001] The invention belongs to the field of hybrid electric vehicles, in particular to an automobile multi-mode hybrid coupling device. Background technique [0002] In today's world, human beings are facing the two major challenges of energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis, and electric vehicles have become the development theme of the automobile industry. Among them, hybrid electric vehicles have excellent performance in terms of energy saving and environmental protection, technology maturity, and overall vehicle performance, and have become the direction of the industrialization of electric vehicles today. There are three types of drive systems for hybrid vehicles: series, parallel and hybrid. Series connection can realize the optimal control of the engine, but all the energy will be converted twice, and the loss is relatively large; parallel connection can achieve better transmis...
