汽车列车电控制动系统制动力分配的控制算法

摘要

为汽车列车提出了一种基于滑移率的电控制动系统制动力分配算法,即根据不同情况,使牵引车后轮和半挂车车轮的目标滑移率随牵引车前轮滑移率而变化.运用Matlab/Simulink和Trucksim软件进行列车在高附着和低附着路面上行驶的联合仿真,结果表明该算法能缩短汽车列车的制动距离,提高了制动稳定性.%A slip-rate-based braking force distribution algorithm is proposed for the electric braking system of combination vehicle, in which the objective slip rates of tractor's rear wheels and semitrailer's wheels change with the slip rate of tractor's front wheel. A co-simulation with Matlab/Simulink and Trucksim software on vehicle running on both high and low adhesion roads is performed. The results show that the algorithm can shorten the braking distance of combination vehicle, enhancing its braking stability.
