The invention relates to a driving controller for a permanent magnet fault-tolerant hub motor of an electric armoured car. The driving controller comprises a DSP system, an FPGA system, an isolation driving circuit, a fault-tolerant power driver and a signal conditioning circuit; the controller acquires phase winding current signals of the motor by utilizing a hall current sensor; a rotary transformer acquires position and rotation speed signals of a motor rotor; simultaneously, according to non-fault two-phase winding current signals of the motor, the position and rotation speed signals of the motor rotor are estimated by utilization of a sensor-less control method; the two detection methods of the position and the rotation speed of the motor rotor are redundantly backed up to each other;and therefore, the motor position / speed detection reliability is improved. The driving controller in the invention has good fault isolation capability and fault-tolerant running performance; the system conversion efficiency is high; and high-reliability, high-power, high-efficiency and small-volume performance requirements of the hub of the electric armoured car can be effectively satisfied.
