摘　　要：以某匹配感载比例阀的车辆为例,以理想利用附着系数曲线为目标,以ECE制动法规为约束条件,利用非支配排序遗传算法对车辆在空载、半载和满载状态下的制动性能进行了多目标优化,得到了满足设计要求和性能最优的感载比例阀静特性曲线。This paper takes a vehicle with SABS as example,using NSGA-II to carry out multi-objective optimization to the braking performance of vehicle under empty-loading,half-loading and full-loading conditions with ideal usage of adhesion coefficient curve as target,ECE braking regulation as restraint condition,and obtains the optimal SABS which satisfies the requirement of design and performance.
