The invention relates to the technical field of automobile brake system development, in particular to a vehicle brake disc control method and device.The method comprises the steps that a current wheel speed pulse signal, a wheel cylinder pressure signal and an environment temperature signal of a vehicle are obtained; estimating the current temperature of the brake disc according to the current wheel speed pulse signal, the wheel cylinder pressure signal and the environment temperature signal; and the optimal braking force of the brake disc is matched according to the current temperature, and the brake disc is controlled to output the optimal braking force. Therefore, the problems that in the related technology, due to the fact that gravitational potential energy does work, the temperature of the brake disc rises, an energy conservation mode needs to peel off gravitational potential energy to do work, the applicability and reliability of brake disc control are reduced, and the accuracy of brake disc control is
