Work vehicle including diesel particulate filter (DPF) regeneration control

A work vehicle, comprising:

• a diesel particulate filter (DPF) system configured to collect particulate matter contained in exhaust gas from an engine;
• a selective catalytic reduction (SCR) system including a reductant stored in a reductant storage tank, the SCR system configured to add the reductant to the exhaust gas so as to reduce nitrogen oxide contained in the exhaust gas;
• and
• a control unit configured to:
• execute a DPF renewal control whereby particulate matter collected and deposited in the DPF system is burned and removed using heat from the exhaust gas, and
• execute an SCR reference operation restricting control configured to restrict a fuel injection amount of an injector, restrict a rotational speed of the engine, restrict a maximum torque rotational speed of the engine, or reduce an output of the engine when an amount of the reductant stored in the reductant storage tank is a preset amount or less or when an abnormality occurs in the SCR system,
• wherein the control unit is further configured to prioritize the DPF renewal control over the SCR reference operation restricting control.
