Patent ID: 7959538

Claim:
A device for controlling an engine and a hydraulic pump of a working vehicle in which power of the engine is provided to a traveling power train and the hydraulic pump; driving wheels are driven through the traveling power train; and work equipment is operated through the hydraulic pump, the device comprising: accelerator operation means that sets a target speed of the engine according to an operation amount; engine speed adjusting means that adjusts a speed of the engine to an ordered target speed; hydraulic pump adjusting means that adjusts a displacement of the hydraulic pump so as to obtain an ordered discharge flow rate; acceleration amount detection means that detects that the operation amount of the accelerator operation means or the engine speed is a prescribed threshold value or higher; brake operation means that sets a braking force for a vehicle body according to an operation amount; brake means that generates the braking force so as to obtain the braking force set by the brake operation means; braking detection means that detects that the brake means is activated or that the brake operation means is operated; vehicle speed detection means that detects that a speed of the vehicle body is a prescribed threshold value or higher; and engine and hydraulic pump control means that provides the engine speed adjusting means with an order to decrease the target speed of the engine, and to cover a decrease in the discharge flow rate of the hydraulic pump due to the order, provides the hydraulic pump adjusting means with an order to maintain the discharge flow rate of the hydraulic pump, on conditions that the acceleration amount detection means detects that the operation amount of the accelerator operation means or the engine speed is the prescribed threshold value or higher; the braking detection means detects that the brake means is activated or that the brake operation means is operated; and the vehicle speed detection means detects that the speed of the vehicle body is the prescribed threshold value or higher.
