摘要
为了感知汽车姿态,利用MEMS传感器自主设计了一种车载微惯性测量单元(MIMU),详细介绍了三轴MEMS加速度计、三轴MEMS陀螺和正六面体的设计。该单元具有成本低、精度高、体积小,且便于标定等优点,可以方便地运用到汽车姿态实时监测系统中。给出了单元的标定方法,分析了其误差来源,建立误差模型以及自主设计了标定系统。实验结果表明:该单元能有效地消除信号干扰,具有满意的精度要求,可对运用该单元进行汽车姿态监测等提供理论研究与工程应用参考。
A set of vehicle micro inertial measurement unit（MIMU） is independently designed using MEMS sensors for vehicle attitude perception and design of three-axis MEMS accelerometer,three-axis MEMS gyro,and a cube are described in detail.The unit has advantages of low cost,high precision,small size and easy-to-calibration,which can apply to vehicle attitude real-time monitoring system.Calibration method of the unit is given,its error sources is analyzed and error models is set up,and calibration system is independently designed.The experiment shows that the unit can effectively eliminate signal interference and reach satisfied precision.It provides a reference for theoretical research and engineering application by using the unit for vehicle attitude monitoring.
