PROBLEM TO BE SOLVED: To provide a working machine capable of calculating a moving speed with improved accuracy even when a current moving speed of a machine body cannot be calculated using signals from a GPS satellite.SOLUTION: A working machine speed (V) is correlated with a GPS speed (V) based on siganls from a GPS satellite obtained when the working machine speed (V) is detected. A correction function for correcting the working machine speed (V) is derived, and by using the derived correction function, an actual speed (V) of a machine body (2) is calculated. The working machine speed (V) is corrected using the derived correction function; therefore, even when signals from the GPS satellite cannot be used, the accuracy of the moving speed can be improved. |
