The invention relates to a position-sensorless full-speed control method for an embedded permanent magnet hub motor. The method comprises the following steps: acquiring an operation signal of a target motor; determining the current operation condition of the target motor according to the operation signal and a preset condition judgment model; the operation condition comprises a zero-low-speed condition and a medium-high-speed condition; determining a rotor angle estimation position of the target motor by adopting a corresponding operation mode according to the operation condition; and controlling the operation of the target motor according to the rotor angle estimation position. By adopting the method, the full-speed control of the position-sensorless wheel hub motor under different working conditions can be realized.
