Abstract
A drive control apparatus for a forklift. Based on the load state, it is determined whether to limit a maximum vehicle speed and an acceleration/deceleration during traveling of the forklift. Limitation contents regarding the maximum vehicle speed and the acceleration/deceleration is determined based on a determination result of whether to put the limitations. A speed of the engine is adjusted based on the determined limitation contents, thereby controlling driving of the forklift. When the determined limitation contents are changed, an acceleration/deceleration limitation value is selected from a plurality of acceleration/deceleration limitation values according to the pattern of the change of the limitation contents, and drive control related to the acceleration/deceleration is executed to limit the acceleration/deceleration of the forklift by using the selected acceleration/deceleration limitation value.
