一种基于制动盘温度对车辆动态控制时的制动力补偿方法

The invention discloses a braking force compensation method based on a brake disc temperature during dynamic control of a vehicle, which comprises the steps of obtaining the brake disc temperature and an original braking force, wherein the brake disc temperature is calculated by a line control movable product according to an original signal of the vehicle, determining a basic compensation coefficient corresponding to the brake disc temperature from a compensation coefficient curve, constructing the compensation coefficient curve according to a corresponding relation between the brake disc temperature and the compensation coefficient, calculating a target braking force according to the basic compensation coefficient and the original braking force, carrying out temperature gradient correction on the target braking force, carrying out filtering treatment and limit control on the corrected target braking force, and outputting a final target braking force. According to the invention, through dynamic association of the temperature of the brake disc and the braking force compensation, accurate correction of the braking force in a full temperature section of-50 ℃ to 600 ℃ is realized, and meanwhile, the deviation of the braking force output is greatly reduced by combining with temperature gradient correction, so that the control precision is remarkably improved.
