摘要
为了给汽车安全控制系统提供准确的行驶姿态数据,设计了基于集成微机电系统(IMEMS)传感器的虚拟仪器检测系统。系统采用IMEMS传感器采集车身姿态参数,在虚拟仪器平台下对数据进行分析处理,使用卡尔曼滤波器对测量值进行估计,并在实车工况下对检测系统进行测试。结果表明:系统能够很好地满足汽车行驶姿态检测的要求,具有可靠的实时性。
In order to provide accurate vehicle attitude parameters for vehicle safety control system,a virtual instrument detecting system based on IMEMS sensor is designed.An IMEMS sensor is used to collect vehicle attitude parameters in the system.Data analysis and processing is conducted on the virtual instrument platform.Kalman filter is adopted to estimate the measurement values.The detecting system is test in real vehicle running condition.The results show that the system can meet the requirement of vehicle attitude detection very well,and it is reliable real-time.
