The embodiment of the invention provides a torque signal processing method, an EPS sensor and a storage medium, and the method comprises the steps: determining the duty ratio of a first PWM signal according to a first voltage collected by a first torque sensor, an average initial voltage and a conversion coefficient; and determining the duty ratio of the second PWM signal according to the second voltage collected by the second torque sensor, the average initial voltage and the conversion coefficient. Calculating an average initial voltage according to a first initial voltage collected by the first torque sensor and a second initial voltage collected by the second torque sensor when the torque is 0, and calculating a conversion coefficient according to the first voltage collected by the first torque sensor, the second voltage collected by the second torque sensor, the average initial voltage and the conversion coefficient; a duty cycle of the first PWM signal and a duty cycle of the second PWM signal are determined. The initial voltage adopts the average initial voltage, so that the offset of the torque detected by the two torque sensors relative to the theoretical value can be averaged, and the error of the duty ratio of the actually output PWM signal is small.
