The invention relates to a hybrid vehicle compound planetary gear set dynamic coupling mechanism. The hybrid vehicle compound planetary gear set dynamic coupling mechanism comprises an engine, a first planetary gear set, a second planetary gear set, a first motor and a second motor; the first planetary gear set is composed of a first sun gear, a first planet carrier, a first tooth ring and a planetary gear; the second planetary gear set is composed of a second sun gear, a second planet carrier, a second tooth ring and a planetary gear; the first tooth ring of the first planetary gear set is connected with the engine through a clutch, the first planet carrier is fixed on a vehicle frame, and the first sun gear is fixedly connected with a rotor of the first motor; the second sun gear of the second planetary gear set is fixedly connected with the first tooth ring of the first planetary gear set, the second planet carrier is fixed on the vehicle frame, the second tooth ring is fixedly connected with a rotor of the second motor, and the second tooth ring is combined with a differential mechanism in order to output power. According to the invention, the function that the engine can directly drive the vehicle, multiple dynamic coupling and mode switching can be achieved, and the implementation structure of the hybrid vehicle compound planetary gear set dynamic coupling mechanism is simple in structure and low in control demand.
