The invention discloses a heavy truck braking system performance judgment method, which comprises the following steps of: acquiring the maximum braking deceleration which can be reached by a whole truck: acquiring a braking force distribution curve, and carrying out region division on the braking force distribution curve; and the locking conditions of front and rear wheels are judged according to the area where the beta line endpoint is located. When the braking performance of the whole automobile is estimated, the locking conditions of the front axle and the rear axle are judged according to the mutual relation of the F line, the R line and the beta line in the automobile theory, so that a solution is given theoretically for accurately calculating the braking performance, and rapid and accurate braking performance analysis is achieved.

    本发明公开一种重卡制动系统性能判定方法,包括:获取整车可达到的最大制动减速度,具体过程包括:获取制动力分配曲线,并对制动力分配曲线进行区域划分;依据β线端点所在区域判断前、后车轮的抱死情况。本申请在对整车制动性能进行预估时,根据汽车理论中的F线、R线与β线的相互关系,来判定前、后轴的抱死条件,从而为准确计算制动性能从理论上给出解决方案,实现快速、准确的制动性能分析。
