Measurement of a vehicle motion using a new 6-DOF accelerometer

This paper investigates a estimation method of angular velocities and attitude angles from acceleration signals. Our sensor system measures 6-DOF motions by resolving multiple acceleration signals. In this estimation, we combine the motion characteristic with a Kalman filter. Our method generates a required observational signal, and non-periodically corrects to the observational signal using detected translational accelerations with gravitational components. Finally, we investigated the proposed method in an experiment involving vehicle motion, and demonstrate that our sensor system and the proposed method perform well.
