The invention relates to the technical field of electric bicycles, and discloses a virtual torque generation method and a virtual torque sensor, a controller collects attitude and pedaling frequency and/or rotating speed signals, and generates a virtual torque signal depending on the input quantity; when signals of the attitude sensor are input and pedaling frequency and/or rotating speed signals exist, the controller outputs virtual torsion in proportion according to the size of the pitch angle and the speed of the pedaling frequency. According to the virtual torque generation method and the virtual torque sensor, a multi-axis attitude sensor is arranged and matched with a pedaling frequency and a speed signal, a virtual torque signal and riding torque of a virtual vehicle in different riding states are generated through a data fusion algorithm, and replacement of a high-end real torque sensor is achieved.
