ODOMETRY ERROR CORRECTION METHOD OF FOUR-WHEEL VEHICLES CAPABLE OF IMPROVING THE ACCURACY OF FOUR-WHEEL VEHICLE POSITION RECOGNITION IN AUTOMATIC VEHICLE OPERATION

摘要

PURPOSE: An odometry error correction method of four-wheel vehicles is provided to accurately correct odometry errors due to systematic errors without adding a sensor.;CONSTITUTION: A systematic error correction model is established by modeling with respect to systematic errors of four-wheel vehicles according to the driving along a test track(S41). A correction target four-wheel vehicle drives along the test track(S42). A systematic error parameter is calculated(S46). The calculated systematic error parameter is applied to the systematic error correction model(S47). The systematic error of four-wheel vehicle is corrected.;COPYRIGHT KIPO 2012
