The invention relates to a braking system suitable for a manpower-driven vehicle. The braking system comprises a warning lamp, an acceleration sensor and a processor which are arranged on the vehicle.The acceleration sensor is used for detecting braking acceleration Ab generated by braking and transmitting the acceleration Ab to the processor; the braking system further comprises an arithmetic mean filter and a dynamic low-pass filter which are used for removing noise signals generated by uneven ground; the braking system further comprises an automatic angle compensation system which is usedfor correcting the component acceleration G'of the gravitational acceleration G generated by the angle difference between the axis of the acceleration sensor and the driving direction of the vehicle;the processor is used for receiving the braking acceleration Ab and the component acceleration G ', carrying out data analysis, judging whether the braking acceleration reaches a threshold value or not, and outputting a braking enabling signal after the braking acceleration reaches the threshold value; and a warning lamp which is used for receiving the brake enabling signal and sending out a lightwarning. According to the system, the brake detection algorithm is simplified, the calculation amount is reduced, the performance and energy consumption requirements of the processor are reduced, andthe brake detection response time is reduced by 100ms.
