摘　　要：将虚拟仪器技术应用于车辆制动性能的测试 ,给出了系统组成 ,进行了软件系统设计 ,研究了数值积分和数值微分算法在车速信号处理中应用 ,并将系统应用于实际 ,得到了车辆位移和制动减速度在制动过程中的变化情况。The virtual instrument technology is applied to the vehicle braking performance test, and the system components of testing instrument are presented. According to the software system designed by the authors, the applications of the numeric integration and derivative algorithm are investigated to the speed signal processing. By means of using this system in practice, the changing situations on vehicle displacement and deceleration are obtained in the braking process.
