Abstract
A work machine includes a vehicle body, a work implement, an attitude sensor, an object sensor, and a controller. The work implement is movably attached to the vehicle body. The attitude sensor detects the attitude of the work implement. The object sensor is attached to the work implement. The object sensor detects an object in a periphery of the work machine, and outputs a signal indicating a presence of the object. The controller sets a detection determination range of the object sensor. The controller determine the presence of the object in the detection determination range based on the signal from the object sensor. The controller calculates sensor attitude data including at least one of a position and an orientation of the object sensor, based on the attitude of the work implement. The controller modifies the detection determination range in accordance with the sensor attitude data.
