【摘要】汽车运动姿态测量正朝着实验平台体积更小化、数据更全面化等方向发展.为了得到更准确、稳定的数据,进行了应用MEMS陀螺仪和加速度计的汽车运动姿态测量.利用卡尔曼滤波算法将MEMS陀螺仪和加速度计输出的数据进行滤波融合,经姿态解算后传至上位机,通过上位机界面实时显示三轴的加速度、角速度和角度,形成存储文件并保存在存储模块中,为研究汽车在不同运动姿态下的运动规律,提高汽车行驶安全性能提供一定的参考依据.%The measurement of vehicle motion attitude is developing towards smaller size and more comprehensive data.In order to get more accurate and stable data,the vehicle motion attitude measurement based on MEMS gyroscope and accelerometer was carried out.Firstly,the Calman filter is used to filter the output data of gyroscope and accelerometer,and after the algorithm is solved,the data will be transmitted to the host computer.Secondly,the three axis acceleration,angle velocity and angle are displayed by host computer interface live,and the storage file is constructed and stored in the memory module.The study will provide references for researching the motion law of the vehicle in different motion states and the improvement of vehicle driving safety. 【总页数】7页(48-54)
