Abstract

The invention discloses a thermal management method and device of a brake disc, computer equipment and a storage medium. The thermal management method of the brake disc comprises the steps that a whole vehicle fluid mechanics model is used for calculating convective heat transfer coefficients of all positions on the brake disc at the current vehicle braking moment; obtaining the temperature of each position on the brake disc at the current vehicle braking moment and the vehicle speed at the current vehicle braking moment; according to the convective heat transfer coefficient and the temperature of each position on the brake disc and the vehicle speed of the vehicle, the temperature variation of each position on the brake disc is calculated; predicting a temperature peak value on the brake disc at the next moment according to the temperature variation and the temperature of each position on the brake disc; and when the temperature peak value on the brake disc at the next moment does not meet the preset temperature condition, a cooling system of the vehicle is controlled to cool the brake disc till the temperature peak value on the brake disc meets the preset temperature condition. According to the method, the heat dissipation effect of the brake disc is enhanced.
