摘　　要：为了避免商用车车辆超载现象及其导致的事故,本文针对商用车加装的电子控制空气悬架系统(ECAS)进行了大量试验和研究,优化了控制策略、控制逻辑、系统布置和配置等方面,改善了车辆转弯稳定性、减少了制动前倾幅度和轮胎磨损。通过模拟仿真和实际测试,可以得到最优结果为:空压机开启时间为3.5 s、电磁阀频率为22 kHz和气压差为0.56 MPa时,系统响应最快,能耗最低。In order to avoid overloading of commercial vehicles and the accidents caused by it,this paper has carried out a lot of tests and researches on the electronic control air suspension system(ECAS)added to commercial vehicles,optimized the control strategy,control logic,system layout and configuration,improved the vehicle’s cornering stability,reduced the brake forward tilt amplitude and tire wear.Through simulation and actual test,the optimal results can be obtained as follows:when the opening time of the air compressor is 3.5 s,the frequency of the solenoid valve is 22 kHz and the air pressure difference is 0.56 MPa,the system has the fastest response and the lowest energy consumption.
