Classification: CPC E  G | IPC E  G

Claim 3:
4. The construction machine according to claim 1, wherein the plurality of movable parts include:
a boom coupled to the upper revolving structure;
an arm coupled to a tip end side of the boom; and
a working tool coupled to a tip end side of the arm,
the plurality of inertial sensors include:
a first inertial sensor that is mounted on the boom and uses a first axis of the three coordinate axes as a determining coordinate axis;
a second inertial sensor that is mounted on the arm and uses a second axis of the three coordinate axes as a determining coordinate axis; and
a third inertial sensor that is mounted on the working tool and uses a third axis of the three coordinate axes as a determining coordinate axis, and
the controller determines the first inertial sensor as a boom inertial sensor in case an angular velocity of the first axis is equal to or more than a first axis determination threshold value and the plurality of movable parts are operated, determines the second inertial sensor as an arm inertial sensor in case an angular velocity of the second axis is equal to or more than a second axis determination threshold value, and determines the third inertial sensor as a working tool inertial sensor in case an angular velocity of the third axis is equal to or more than a third axis determination threshold value.
