Description

technical field

[0001] The invention relates to a drive system belonging to the technical field of hybrid vehicles and vehicle transmissions, more precisely, the invention relates to a hybrid drive system with a three-clutch automatic transmission and a control method. Background technique

[0002] The characteristics of energy saving and low emission of the hybrid drive system have aroused great concern in the automobile industry and become a focus of automobile research and development. The transmission in the hybrid powertrain is a key component to ensure that the engine and drive motor work in the speed range with the best output characteristics. In the hybrid drive system configuration, there are generally two ways to arrange the drive motor in the prior art: one is that the drive motor is placed before the transmission, and the other is that the drive motor is placed after the transmission. Two different positions of the drive motor Corresponds to two different hybrid...
