<p><P>PROBLEM TO BE SOLVED: To carry out efficient regeneration of a diesel particulate filter provided in a discharge path of exhaust gas. <P>SOLUTION: The working vehicle is equipped with a diesel engine provided with a diesel particulate filter 46b collecting particulate matter PM in exhaust gas. In the working vehicle, an amount of soot to be discharged is estimated and calculated based on values detected by an engine rotation sensor R which detects the rotation number of the engine and a fuel injection amount sensor Q which detects a fuel injection amount, using a soot detection map 68. Further, if a value detected by an altitude sensor P which detects an altitude at which the working vehicle is located takes a value equal to or more than a prescribed value, the amount of soot to be discharged is subjected to correction and is then estimated and calculated using an altitude correction map 69. The diesel particulate filter 46b is regenerated based on the corrected, calculated, and estimated amount of soot. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
