A Strapdown Measurement of Vehicle Posture
Vehicle bodywork posture measurement has been a gordian technique in automotive．This paper presented a non-gyro bodywork posture measurement program．Using only one triaxial acceleration transducer with wheel speed encoders it provided a solution of calculating real-time bodywork posture．A lot of streamlining had been made within this program in order to assurance system for real-time performance．Concretely it gave an example of hardware implementation circuit through using LPC1758 as MCU and MMA7260 as triaxial accelerometer, as well as the noise filtering solusion for the circuit．This strapdown measurement has the advantages of high reliability，adaptability and good real-time performance，its precision meets the necessary accuracy requirement of normal application.
