WORK VEHICLE
Document Type and Number:
Japanese Patent JP2020090920
Kind Code:
A
Abstract:
To provide a work vehicle capable of making an instruction for appropriately reducing an engine rotation speed especially while preventing a sudden rise in the engine rotation speed without instructing the erroneous engine rotation speed to the side of an engine 2 on the basis of an idea of fail safe in a case that there is abnormality in sensors 39 and 42 for detecting a manipulated variable of an accelerator lever 27 or an accelerator pedal 30.SOLUTION: Detection values of detection means 39 and 42 for detecting manipulated variables of an accelerator lever 27 and an accelerator pedal 30 are acquired and predetermined engine rotation speeds are set. A higher engine rotation speed of the set engine rotation speeds is instructed to the side of the engine 2. In a case that the presence of abnormality in the detection value of the detection means is determined, the setting of the engine rotation speed of the detection means in which the presence of abnormality is determined is set to a lowest engine rotation speed.SELECTED DRAWING: Figure 5
