Sensing The Vehicle Dash Through Gps

[Full Text]



Lway Faisal Abdulrazak



Vehicle Dash, GPS, Sensor, Acceleration error.



most vehicular application calculating a vehicle speed is very important. In this paper when GPS is not available vehicle speed is calculated by using sensor in the smartphone. Vehicle speed is estimated by calculating the accelerometer and find the acceleration error since it leads to large deviation between calculated speed and the real speed. The acceleration error can be corrected at a point called reference point. Vehicle speed is exactly known through reference point. In urban environment which includes many turn, passing through uneven roads to eliminate the acceleration error caused by estimated speed deviation and to derive reference point. Estimation error on real time in local road is 32mph and in offline is 0.75mph and the GPS average error is 3.1mph and 2.8mph.
