ABSTRACT:
A traveling operation detecting portion detects traveling operation and non-traveling operation selectively. The traveling operation corresponds to operator operation that involves traveling of an industrial vehicle. The non-traveling operation corresponds to operator operation that does not involve the traveling of the industrial vehicle. An upper setting portion selectively sets a first engine speed upper limit and a second engine speed upper limit, which are different from each other, as an upper limit of an acceptable speed range of an engine in correspondence with a detection result of the traveling operation detecting portion. Thus, maximum advantage of the performance of the engine is ensured in correspondence with operation of the industrial vehicle.
