Abstract

See full text

A type of an object is determined and the movement direction of the object is predicted on the basis of a sensing result of the object sensed by an on-machine obstacle sensor. Information relating to the object that is the object sensed by the on-machine obstacle sensor and has been determined to have moved to the outside of a sensing range of the on-machine obstacle sensor is immediately deleted from an environment map on the basis of the type and the movement direction of the object. This can properly process information on the object that has gotten out of the sensing range, according to the cause of the object getting out of the sensing range.
