<p><P>PROBLEM TO BE SOLVED: To provide a vehicle speed control apparatus of a working vehicle for preventing sudden acceleration when a vehicle speed moves from a state of not reaching to a target speed, due to a heavy load, to a state of releasing the load, and reducing a resultant shock and eliminating uncomfortable operational feeling. <P>SOLUTION: The apparatus comprises an operation variable detecting means for detecting operation variable of accelerator means of the working vehicle, an actual vehicle speed detecting means for detecting an actual vehicle speed of the working vehicle, a measuring means for measuring a load of the working vehicle, and a controller for performing a first control for controlling the vehicle speed so that a difference between the target vehicle speed and the actual vehicle speed of the working vehicle becomes zero according to a load measured by the measuring means after setting the target vehicle speed corresponding to the operation variable detected by the operation variable detecting means, or a second control for controlling the vehicle speed of the working vehicle so that the difference between a corrected target vehicle speed and the actual vehicle speed becomes zero after correcting the target vehicle speed to a low value corresponding to the actual vehicle speed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
