The invention discloses a distributed driving electronic differential self-adaptive control system. The system comprises a power supply device, an accelerator pedal, a steering wheel and corner sensor, a vehicle speed estimator, a signal preprocessor, an electronic differential controller, a motor controller, a wheel speed sensor, an accelerator pedal sensor, a brake pedal sensor, a driving motor,an input signal processing module, a whole vehicle driving control module and a driving torque output module; wherein the input signal processing module is connected with the whole vehicle driving control module, and the whole vehicle driving control module is connected with the driving torque output module. The whole vehicle coordination control model and strategy of a double-layer structure with the upper layer as the driving force distribution layer and the lower layer as the slip rate control layer are adopted. According to different driving conditions of an automobile, wheel equal powerdistribution control, a yaw moment control strategy based on fuzzy control and a self-adaptive electronic differential control strategy based on similar wheel slip rates are used for achieving multi-mode coordination control.
