The embodiment of the invention provides a distributed driving electric vehicle fault limp maneuvering enhancement control method and system, and relates to the technical field of data processing. The method comprises the steps that current vehicle parameters and hub motor fault information are obtained; calculating the current vehicle parameters based on a preset expected state estimation model to obtain a vehicle state control target; the current vehicle parameters and the vehicle state control target are calculated based on a preset optimization control model, and the direct yawing moment and the active front wheel turning angle are obtained; determining an initial torque adjustment parameter corresponding to the hub motor fault information; torque compensation distribution information is determined based on the hub motor fault information and the direct yawing moment; integrating the initial torque adjustment parameter and the torque compensation distribution information to obtain target torque adjustment information; and determining the target torque adjustment information and the active front wheel rotation angle as current control information of the distributed driving electric vehicle. The driving stability of the vehicle can be improved.
