Abstract
When a vehicle speed of a wheel loader () is determined to be not higher than a reference value (Yes) in step Sand a forward/reverse command switch () is determined to have been switchingly operated (Yes) in step S, the routine advances to step Swhere an increment ΔN of engine speed according to an engine load factor is determined. In step S, the increment ΔN of engine speed is then added to a target engine speed Na corresponding to a depression stroke of an accelerator pedal (), the thus-determined Na=Na+ΔN is set as a new target engine speed Na, and a target engine speed command iis sent to an engine controller ().
