Based on SAS software platform,the move contrail fitting equation of automobile gear shifting manipulator is constructed with applying method of stepwise regression analysis.The correctness of the equation is proved and all the effect factor is analysed.The experiment data indicate that the equation preferably fit the precision request of manipulator displacement measurement.
