A multi-mode electric drive system includes a Ravigneaux planetary mechanism, a first motor, a second motor, and a system output shaft, where the first motor is connected to a second sun gear of the Ravigneaux planetary mechanism, the second motor is connected to a first sun gear of the Ravigneaux planetary mechanism, a ring gear of the Ravigneaux planetary mechanism is connected to a corresponding housing through a first lock-up clutch, the first sun gear of the Ravigneaux planetary mechanism is connected to the corresponding housing through a second lock-up clutch, and a planet carrier of the Ravigneaux planetary mechanism is connected to the system output shaft. A vehicle including the electric drive system is also disclosed. Based on the working principle of the Ravigneaux planetary mechanism, working states of the first lock-up clutch and the second lock-up clutch are controlled to enable the multi-mode electric drive system to operate in different pure electric drive modes, such that the system can be adjusted to a suitable drive mode based on the actual situation. When the system operates in a suitable drive mode, the operating efficiency of the system can be ensured.
