%X 为提高汽车制动性能，以电子驻车制动器的摩擦片为研究对象，采用模拟退火算法与MISQP算法组合的优化方法，以制动力矩最大与摩擦片体积最小为目标函数。结果显示，制动力矩提升10.9%，摩擦片体积减小2.014 cm<sup>3</sup>。电子驻车制动器具有液压盘式制动与电子驻车制动两种制动模式，通过仿真分析与实车验证，结果显示，优化后的摩擦片结构在高速高附着系数路面的制动性能提升较为明显，液压盘式制动下的制动距离缩短1.08 m，电子驻车制动下的制动距离缩短6.16 m。<br />
In order to improve the braking performance of the electronic parking brake, a combination of simulated annealing algorithm and MISQP algorithm was used to optimize the friction disc, with the maximum braking torque and minimum friction disc volume as the objective functions. The results show that the braking torque is increased by 10.9% and the friction disc volume is reduced by 2.014 cm<sup>3</sup>. The electronic parking brake has two braking modes: hydraulic disc brake and electronic parking brake. Through simulation analysis and real vehicle verification, the results show that the braking performance of the optimized friction plate structure on the high-speed and high adhesion coefficient road surface is significantly improved, and the braking distance is shortened by 1.08 m under the hydraulic disc brake and 6.16 m under the electronic parking brake.
