<p>In a construction vehicle 100, the response speed of control for preventing a drive force 120 from becoming excessively great when a high drive force task is being performed is improved. The construction vehicle 100 is provided with an engine 130, a clutch 140, a travel device 138, a work equipment 106, a drive force setting dial 162, and a controller 160; and the controller 160 includes: a theoretical value determination unit that determines a theoretical value, which is a value that the degree of engagement should assume in order to make the upper limit value of the drive force 120 be equal to a set drive force; an operational state determination unit that performs operational state determination for determining whether or not the work equipment is performing a task of a predetermined type and moreover the travel device 138 is outputting the drive force 120 in a predetermined travel direction; a drive force determination unit that performs drive force determination in which it is determined whether or not the drive force 120 is greater than the set drive force; and a degree of engagement reduction unit that, if the result of operational state determination and the result of drive force determination are both affirmative, reduces said degree of engagement so that it approaches the theoretical value.</p> |
