| Abstract: | In order to achieve the safety operation state monitoring and solve the problem of monitoring body motion gesture of vehicle, the principle of Gyroscope-free Strap-down Inertial Navigation System （GFSINS） used in aircraft navigation is introduced in this article. A monitoring model of vehicle body motion gesture, which is based on three-dimensional accelerometer at cube＇s four vertices, is structured. The design and implementation of vehicle embedded intelligent acceleration sensor unit is studied. The experimental results show that the speed measurement error of the intelligent acceleration sensor unit is 1.98% and response time is 0.38S, which meet the application requirements. |
