According to the calibrating requirements of force sensor on friction vehicle, a calibrating method for runway friction vehicle was proposed and the calibrating principle and method was analyzed. PC104 module was selected as the control core to complete calibrating experiments. Aiming at the nonlinearity of force sensor, the segment least square(LSQ) was adopted to fit data and the results of experiment validated its efficiency.
