Abstract

The invention discloses a power shunting hybrid power coupling mechanism and a control method thereof. The coupling mechanism comprises an engine, a motor, a compound planetary gear mechanism, clutches and a shaft gear system; the compound planetary gear mechanism is a double-row compound planetary mechanism, wherein a first planetary carrier is connected with a second inner gear ring, and a firstinner gear ring is connected with a second planet carrier; and the motor is connected with a second sun gear. According to the power shunting hybrid power coupling mechanism, a pure electric power mode, two hybrid power modes and three power shunting modes can be arranged, the mode can be switched through opening and closing between the clutches and the operation of a brake, so that the power efficiency can be effectively improved, and the economy is improved; and the engine and the motor of the whole mechanism are connected through the planetary gear, so that the adjustable range of the speed ratio is wide, the size of the motor can be reduced, and the operating range of the engine can be optimized.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a power-split hybrid coupling mechanism and a control method thereof. Background technique [0002] The power of automobiles has always been the research focus of major manufacturers. With the improvement of technology, the source of automobile power has also developed from the original single internal combustion engine to diversification. At present, many new energy technologies have emerged. New energy vehicles include pure electric vehicles. , hybrid vehicles, fuel cell vehicles. However, pure electric vehicles are subject to battery technical problems, and it is difficult to break through in a short time. Fuel cell vehicles are limited by issues such as energy preparation and storage, and it is difficult to promote them in the short term. In recent years, hybrid vehicles have been the focus of various car companies. [0003] Generally speaking, the efficie...
