The invention relates to a rotating transformer software decoding based electric power-assisted steering system. The rotating transformer software decoding based electric power-assisted steering system comprises a mechanical steering mechanism, a power-assisted mechanism and an electronic control unit; the power-assisted mechanism comprises a PMSM (Permanent Magnet Synchronous Motor) which is provided with a rotating transformer; the electronic control unit comprises an MCU (Micro Controller Unit) module, a rotating transformer signal processing module, a power driving module and a power supply module; the MCU module is connected with the power driving module and the rotating transformer signal processing module; rotating transformer signal processing module is connected with the rotating transformer; the power driving module is connected with the PMSM. According to the rotating transformer software decoding based electric power-assisted steering system, the expensive hardware decoding scheme is replaced by the low cost of spin variable software decoding scheme which is applied to the electric power-assisted steering system and accordingly the hardware cost of the electric power-assisted steering system is greatly reduced and the decoding algorithm is small in calculation amount and high in accuracy.
