Abstract

The invention discloses a hybrid driving system with a three-clutch automatic transmission and a control method thereof. In order to solve a problem of the traditional hybrid driving system that total powers of an engine and a driving motor cannot be sufficiently utilized or the driving motor cannot always operate within an optimal output characteristic rotation speed range, the hybrid driving system with the three-clutch automatic transmission comprises a first power converter, a starter / generator integrated machine, an engine, a fourth clutch, a driving motor, an energy storage device, a second power converter, the three-clutch automatic transmission, a differential mechanism, a fourth clutch output shaft end gear, a driving motor output shaft end gear and a transmission input shaft end gear, wherein the transmission input shaft end gear is mounted on a transmission input shaft of the three-clutch automatic transmission; and the fourth clutch output shaft end gear, the driving motor output shaft end gear and the transmission input shaft end gear are engaged with each other in sequence. The invention further provides a control method for the three-clutch automatic transmission.

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...
