The invention discloses a hybrid power auxiliary transmission system of a direct-current locomotive and a control method of the hybrid power auxiliary transmission system. The hybrid power auxiliary transmission system comprises an internal combustion generator set, a traction motor loop and an auxiliary power supply system. The auxiliary power supply system comprises a bidirectional DC/DC module, a power battery and an auxiliary system; the auxiliary system comprises a DC/AC inversion module, a cooling fan motor, a traction ventilator motor, an air compressor motor and a DC/DC module. The internal combustion generator set is connected with the auxiliary power supply system through a traction motor loop; the two ends of the DC/AC inversion module are connected with the positive electrode and the negative electrode of the power battery respectively. The two ends of the DC/DC module are connected with the positive electrode and the negative electrode of the power battery respectively. Energy of a power battery and an internal combustion engine set of the direct-current locomotive can be mixed to supply power to the locomotive alternating-current auxiliary system; power can be supplied to a locomotive alternating current auxiliary system only through a power battery or an internal combustion engine set.
