The invention discloses a semitrailer AEB control method considering road adhesion and load change disturbance, and the method comprises the steps: firstly providing an improved safety distance calculation model, then carrying out the early warning distance calculation, and then providing an AEB grading early warning and braking control strategy. According to the method, the influence of load change and road adhesion of the semitrailer train is considered, and the safety braking distance model is improved, so that the braking control strategy is more suitable for the use scene of the semitrailer train, and meanwhile, the adaptability of the AEB control algorithm to the road surface is improved. 本发明公开一种考虑路面附着和负载变化扰动的半挂车AEB控制方法，首先提出改进的安全距离计算模型，再进行预警距离计算，再提出AEB分级预警、制动控制策略。本发明考虑半挂车列车负载变化和路面附着的影响，对安全制动距离模型提出改进，使得制动控制策略更加切合半挂车列车的使用场景，同时提高了AEB控制算法对路面的自适应性。
