摘　　要：为了获取半主动悬架控制中车辆的垂直速度,在分析真实垂直速度信号成分的基础上,提出一种基于垂直加速度计算速度的积分滤波电路和仿真研究方法。本文基于SimScape建立了电气仿真模型,设计了硬件滤波电路,通过离线仿真和硬件在环测试完成了积分滤波电路的开发,并对真实随机路面工况加速度信号进行软硬件处理。实验结果表明,通过软硬件积分滤波系统的信号与离线积分滤波的真实信号保持了较高的一致性,从而验证了积分滤波系统的准确性。To solve the issue of getting vertical speed for semi-active suspension control, an integral filter circuit and simulation method for vertical speed calculation are put forward based on the analysis of real signal components. The electrical simulation model with SimScape for off-line simulation is constructed. The hardware of the filter circuit for Hardware-In-the-Loop （HIL） test is designed. The integral filter circuit system is exploited through real vehicle acceleration signal. The acceleration signal under the real random road condition is processed through off-line calculation. Experiment result show that the signal obtained from the integral filter circuit system simulation is in high consistent with the signal obtained by HIL test, justifying the integral filter circuit system.
