Dynamic torque acquisition system for power-assisted bicycle

The utility model discloses a dynamic torque acquisition system for a power-assisted bicycle. The dynamic torque acquisition system comprises an angle sensor, a pressure sensor I, a pressure sensor II, a memory, a singlechip, a torque sensor and an MCU (Microprogrammed Control Unit), the signal output ends of the angle sensor, the first pressure sensor and the second pressure sensor are all connected with the single-chip microcomputer. The system can more accurately reflect the pedaling force condition of a rider, when one pedal moves anticlockwise in the 12 o'clock direction to the 6 o'clock direction and the pressure sensed by the pressure sensor on the pedal is larger than a threshold value in the storage, the single-chip microcomputer controls the torque sensor to be started at the moment, the torque sensor collects torque information, and the pedal is driven by the single-chip microcomputer to rotate. Compared with an existing torque acquisition system, the pedal force acquisition system has the advantag
