The invention discloses an auxiliary braking system of an electric bicycle and an implementation method. The auxiliary braking system comprises a microprocessor, a brushless direct current motor vector controller, a pressure sensor, an A/D conversion circuit, an input module, a speed sensor and an acceleration sensor. On the basis of a brushless direct current motor adopted by an electric bicycle, electromagnetic torque output by a motor is accurately adjusted through vector control, the electromagnetic torque of the motor, braking torque of a brake and friction force of the ground jointly act on tires, a PID parameter setting device is used for setting parameters of a PID controller of a system, and the optimal control effect is obtained. By accurately controlling the electromagnetic torque of the brushless direct current motor, the slip rate of the electric bicycle is adjusted, the shortest braking distance is obtained, and the braking safety of the bicycle is improved.
