Example 1:
as shown in fig. 1, embodiment 1 of the present invention provides an automobile drive system, which includes an engine 1, an engine output shaft 2, a motor 3, a power coupling mechanism 4, and a transmission input shaft 8, where the power coupling mechanism 4 includes a clutch 7, a lockup clutch 5, and a planetary gear mechanism 6, and the planetary gear mechanism 6 includes a carrier 61, a planetary gear 62, a sun gear 63, and a ring gear 64.

The lockup clutch 5 is disposed between the rotor of the motor 3 and the planetary gear mechanism 6, one end of the lockup clutch 5 is connected with the rotor of the motor 3 and the sun gear 63, the other end of the lockup clutch 5 is respectively connected with the gear ring 64 and the transmission input shaft 8 into a whole, and the lockup clutch 5 is used for being selectively engaged or disengaged to realize an engine and motor common driving mode. Specifically, the locking clutch is engaged to lock the planetary mechanism, and the engine power and the motor power jointly drive the planetary mechanism to integrally rotate.
The power coupling mechanism 4 is used for coupling the power of the engine 1 and the motor 7, and is connected with a transmission 9 through the transmission input shaft 8. Specifically, the transmission 9 is a torque converter-less automatic transmission or a continuously variable transmission.
In the embodiment of the invention, a damping spring assembly 10 is further arranged between the planet carrier 61 and the engine output shaft 2, and the damping spring assembly 10 is used for controlling the engine vibration and reducing the vibration hazard. Specifically, since the impact and the inertia force of the reciprocating motion caused by the combustion of the fuel in the engine generate complex vibration conditions, not only can damage the parts of the automobile itself and deteriorate the working performance or even shorten the service life of the automobile, but also can seriously affect the normal operation of other on-board equipment and instruments and reduce the comfort, so that the vibration hazard of the engine needs to be reduced. The damping spring assembly 10 is used for connecting power transmission between the engine output shaft 2 of the engine 1 and the planetary gear mechanism 6, and a spring for buffering and damping is arranged in the damping spring assembly 10, so that the vibration of the engine can be effectively controlled within a certain range through the damping assembly.

N2+K*N1-(K+1)*N3＝0；
N3 equals 0;
n2 ═ motor speed;
