Research of Attitude Measurement System for Vehicles Based on MEMS Sensors
In this paper, based on the study of a variety of Vehicles attitude measurement system, an attitude measurement system based on MEMS inertial sensors for vehicles is proposed, which can give A full rang e of Vehicles movement attitude information to th e fatigue warning system, and then improve the accuracy of the fatigue warning system. This system can get the attitude information of the carrier by collecting the data of sensors, and then get the attitude information which has been collected back to the car GPS speed measurement device. In this paper, the system program to use the Kalman filter to calibrate and compensate the accumulations of e rrors of the inertial syste m, at the sa me time, supp ort to i ncrease the Anti-interference ability and dynamic performance of the car GPS speed measurement device. Based on error model for INS and GPS attitude determination system for Kalman filter, error and measure equation for INS/GPS attitude determination integrated system can greatly obtain the better performance of integrated navigation system. At last, give the integrated information back to the ca r driver fatigue warning system, to obtain a more accurate early warning information.
