The invention relates to a highly reliable dual redundancy electric steering gear control device. The device includes a bus interface, a control core, a motor driver module, a sensor interface, a rotary transformer interface, a control power interface, a three-phase motor interface, a power supply circuit and a power supply interface. The control core through the bus interface receives a control instruction from a flight control system, and transmits the controlled quantity, direction signal and virtual Hall signal to the motor driver module; the motor driver module outputs to the motor through the three-phase motor interface to drive the motor to run, and the motor through a reducer to complete the diversion. The invention employs the dual redundancy digital bus to communicate with the flight control system and receive diversion instruction transmitted by the flight control system, so as to realize dual redundancy bus redundancy logic, commutation control of a brushless direct current motor and closed loop control of the front wheel diversion in the internal part.
