The invention belongs to the technical field of brake energy recovery, and particularly relates to an electric automobile brake-by-wire energy recovery coordination control system and method. The system comprises a braking intention recognition module, a braking mode judgment module, a braking force distribution module and a braking force control module. An arbitration coordination mechanism between the active safety function and braking energy recovery is established, coordination control over the multiple active safety functions is achieved, and the stability of the vehicle can be guaranteed while braking energy recovery is guaranteed; and an electro-hydraulic braking coordination and mode switching transition control method is designed in the braking force control module, so that the braking force response is more stable, the braking force jerking is reduced during mode switching, and the comfort of a driver and passengers is improved. The problems that a driver feels uncomfortable when the braking energy of the electric automobile is recovered, and the active safety function and the braking recovery are coordinated are solved.
