The invention discloses a device and a method for judging AMT vehicle clutch half joint. The device comprises a signal collecting unit and an electronic control unit, wherein the signal collecting unit comprises an engine speed sensor, a speed change gear shaft speed sensor and a clutch position sensor which are respectively connected with an electronic control unit. The control unit is used for collecting a clutch position signal sent by the clutch position sensor when the engine speed is less than a first preset value after an AMT vehicle enters P shift and the absolute value of the speed change gear shaft speed difference is less than a second preset value. The invention can improve the accuracy of collected clutch half joint, thereby improving the running smoothness of the vehicle, reducing clutch wear, prolonging clutch service life, ensuring steady running of the engine and reducing engine speed fluctuation.
