The invention discloses a torque distribution method and device and an electric automobile, and relates to the technical field of automobile control. The method comprises the steps that the total demand torque of the electric automobile is determined according to the opening degree and the automobile speed of an accelerator pedal of the electric automobile; determining a target torque distribution proportion of a front-drive motor and a rear-drive motor of the electric vehicle according to the vehicle speed, the total demand torque, an expected proportion pre-configured by a user and a plurality of pre-stored torque distribution tables; and according to the target torque distribution proportion and the total demand torque, determining a first output torque of the front-drive motor and a second output torque of the rear-drive motor. According to the scheme, the torque is distributed for the front-drive motor and the rear-drive motor according to customer requirements, and the driving flexibility and the driving experience of a user are improved.
