摘　　要：为实现两桥客车电控空气悬架系统侧跪控制,采用汽车动力学仿真软件TruckSim和逻辑控制软件Simulink&Stateflow开发客车侧跪控制策略。通过TruckSim搭建客车整车车体模型,Simulink构建的电控空气悬架模型,包括空气弹簧模型、储气罐模型、管路模型、电磁阀模型等,借助Simulink&Stateflow建立侧跪控制策略仿真模型,仿真实验结果表明,侧跪前后客车车身高度和气囊压力发生明显变化,车身侧倾角从0°增加至2°,乘客上下车更便利。In order to achieve the kneeling control of the two-axle bus equipped with an electronically controlled air suspension,the vehicle dynamics simulation software TruckSim and the logic control software Simulink&Stateflow were used to develop the bus kneeling control strategy.The full vehicle model of the bus was built using TruckSim,and the electronic control air suspension model,including the air spring model,air tank model,pipeline model,and solenoid valve model,was constructed using Simulink.The simulation model for kneeling control strategy was established with the help of Simulink&Stateflow.Simulation experiments verified the bus kneeling control strategy.The results showed significant changes in bus body height and airbag pressure before and after kneeling,with the body roll angle increasing from 0°to 2°,making it more convenient for passengers to get on and off the bus.
