Novel double-motor coupling power mechanism and control method thereof

The invention provides a novel double-motor coupling power mechanism and a control method thereof. The novel double-motor coupling power mechanism comprises a main driving motor and an auxiliary driving motor, wherein the main driving motor is provided with a first output shaft; the first output shaft is fixedly connected with a first sun gear; a first planet gear set is arranged on the outside ofthe first sun gear; a second planet gear set is arranged on the outside of the first planet gear set; the auxiliary driving motor is provided with a second output shaft which sleeves the outside of the first output shaft; the second output shaft is fixedly connected with a second sun gear; the second sun gear is engaged with the second planet gear set; a clutch is arranged between the first output shaft and the second output shaft; and brakes are separately arranged on the outside of the first output shaft and the outside of the second output shaft. By the two brakes and the clutch, power ofa power system does not in
