This invention discloses a
radar-coordinated braking control method for electric-assist bicycles in complex road conditions, relating to the field of electric-assist bicycle control technology. The method includes acquiring
radar-detected rear target signals, determining the presence of
collision risk based on the
changing trend of the rear target signals, and identifying the
movement pattern of the rear targets; acquiring the rider's pedaling torque
signal; when a
collision risk is determined, predicting the moment when the rider's pedaling torque will begin to decrease based on the
changing trend of the rear target signals; at the predicted moment, initiating mechanical braking pre-pressure and simultaneously reducing the motor's assist output. This invention utilizes residual assist to provide soft support for the rider's
body posture, compensating for the
instability caused by the forward shift of the center of gravity, and solving the timing conflict problem between braking intervention and rider posture changes in existing technologies. This improves braking efficiency in dangerous rear-end scenarios while enhancing the stability and smoothness of the riding process.
