Beschreibung
Zusammenfassung:	The invention provides a control device for a work vehicle and a work vehicle. The present invention provides a control device for a work vehicle capable of reducing the travel speed of a machine bodywith good followability even when the load on a work device is sharply increased. A deceleration rate setting unit (61), a target swash plate position calculation unit (62) sets a target swash plateposition, which is the target position of the swash plate of the hydraulic pump (33), so as to decelerate the travel speed of the machine body from a speed corresponding to the position of the shift lever in accordance with the deceleration rate, in accordance with whether the load rate of the engine exceeds a reference value. Furthermore, the current supplied to the proportional decompression control valves (52, 53) of the HST is controlled so that the position of the swash plate of the hydraulic pump coincides with the position of the target swash plate. 本发明提供一种作业车辆用的控制装置及作业车辆。所述作业车辆用的控制装置即便针对作业装置的负荷的急剧增大，也能够以良好的追随性降
