<P>PROBLEM TO BE SOLVED: To solve such a problem that when outside air temperature is extremely low, regeneration of a DPF (Diesel Particulate Filter) fails because the temperature of the DPF itself decreases regardless of stopping driving of a fan affecting the DPF. <P>SOLUTION: A working vehicle mounts a diesel engine E and a diesel particulate filter 46b that captures a particulate matter PM in exhaust gas, and is configured to control regeneration for removing the particulate matter PM in the diesel particulate filter 46b. The vehicle includes an outside air temperature sensor 70 detecting outside air temperature, and determines an engine speed during controlling regeneration of the diesel particulate filter 46b in accordance with a detection value of the outside air temperature sensor 70. The vehicle is configured to increase an engine speed under the condition of a lower outside air temperature than an engine speed under the condition of a higher outside temperature indicated by detection values of the outside air temperature sensor 70 based on a predetermined threshold M. <P>COPYRIGHT: (C)2012,JPO&INPIT |
