The invention relates to a vehicle brake disc temperature prediction method and related equipment. The method comprises the steps that operation parameters, friction pair parameters and environment parameters of a vehicle are acquired; according to the operation parameters, the friction pair parameters, the environment parameters and a preset heat conduction law, a heat conduction model of the brake disc of the vehicle is constructed; according to the operation parameters, the friction pair parameters, the environment parameters and a preset cooling law, a heat dissipation model of the brake disc is constructed; the heat conduction model and the heat dissipation model are fused into a temperature prediction model of the brake disc; acquiring a real-time braking state of the vehicle; and predicting the brake temperature of the brake disc according to the real-time brake state and the temperature prediction model. The problems that in the friction process of the brake disc, when the thermocouple is abraded, the temperature of the thermocouple and the temperature of the brake disc making contact with the thermocouple rise, the accuracy of the obtained temperature of the brake disc is low, and the safety of the vehicle brake disc is insufficient are solved.
