Abstract

A construction machine includes: an engine driving at least one hydraulic pump configured to supply operating oil to a hydraulic actuator; an exhaust adjustment mechanism adjusting a flow rate of exhaust from the engine; and a control device controlling the exhaust adjustment mechanism. The control device determines whether or not a first downhill traveling condition and/or a second downhill traveling condition are/is satisfied. When at least one of the first downhill traveling condition and the second downhill traveling condition is satisfied, the control device controls the exhaust adjustment mechanism such that the exhaust adjustment mechanism executes exhaust brake.
