Abstract: An early warning method for hot spots of a brake disc includes: acquiring a mixed vibration signal generated when the brake disc is braked; separating the mixed vibration signal to obtain multiple separated vibration signals; and screening the multiple separated vibration signals to obtain hot spot determination signals. The hot spot determination signals are configured to determine formation of the hot spots on the brake disc. By separating the mixed vibration signal generated when the brake disc is braked, the multiple separated vibration signals can be obtained. Each of the multiple separated vibration signals is screened to obtain the hot spot determination signal that reflect whether the hot spots are formed on the brake disc, and the hot spot early warning result is reliable. The early warning method can effectively improve the accuracy of hot spot early warning for brake discs.
