Advantages: Differentially control and supply power to the two motors of the front and rear wheels of the power-assisted bicycle. The content of the differential control is the pre-set model function processing.

The invention discloses a voltage differential control moped system with a gear signal and a speed signal input successively, and belongs to front wheel and rear wheel difference distributing assisting bicycle power supply controller systems for differentially supplying assisting power. The system comprises two wheels and two motors of an electric assisting bicycle and a gear signal manual controller, and further comprises a differential distributor, and the differential distributor comprises three modules connected in sequence. The first module carries out numeric comparison processing on a gear signal ID, a feedback control signal current IA and a feedback control signal current IB. The second module carries out model function processing on the data of the first module. The third module inputs a bicycle uniform speed signal IS into a data distributor (10), control data are processed with speed signal elements added, and a controller A and a controller B obtain the gear signal ID, the feedback control signal current IA, the feedback control signal current IB and the bicycle uniform speed signal IS. The system has the advantages that differential control power supply is respectively carried out on the two motors of the front wheel and the rear wheel of the assisting bicycle, and the content of differential control is preset model function processing.
