摘　　要：设计了一种以飞思卡尔MC9S08GB60单片机为控制核心的汽车电控空气悬架系统。着重阐述了其硬件电路系统和具体电路设计,并对软件设计要点进行了介绍。通过在实验室进行台架测试,验证了本系统相对于被动悬架系统有效的改善了悬架动行程,车轮动载荷及车身垂直加速度三项重要指标,在实现车身高度调节控制的同时改善了车辆乘坐的舒适型。且电路结构简单,稳定性好,有实用应用的价值。The Vehicle＇s electronically controlled air suspension system were designed, which use a microcontroller Freescale MC9S08GB60.Emphasizes the circuit of the hardware system, meanwhile, introduces the key point on the software design. The bench test in laboratory certified that the ECAS relative passivity-suspension , it improved three impotent index arm effectively, which are suspension＇s moving distance, acceleration in vertical and the cartwheel moving loading, it improve the vehicle＇s ride comfortable when controlling the ride height. The system is simple structure stability and practical.
