摘要
The objective of the invention is to output a warning concerning urea water level which can be easily monitored by the operator. Provided is a device to output urea water level warning for utility vehicle (1) that performs exhaust gas treatment using urea water in a urea water tank (42) the device comprising: a urea water level detection unit (23) that detects the quantity of urea water remaining in the urea water tank (42); an operating time measuring unit (24) that measures the operating time of the utility vehicle (1); a unit urea water consumption calculation unit (11A) that computes the unit urea water consumption per predetermined unit of operating time based on the quantity of urea water remaining; a urea water time remaining calculation unit (11B) that calculates the average urea water consumption based on unit urea water consumption within a predetermined operating time in the past by deducting from the unit urea water consumption the unit urea water consumption calculated when a specific phenomenon occurs and calculates the urea water time remaining indicating the time until a urea water level warning is emitted based on the average urea water consumption and the current urea water level; and an output processing unit (11C) that outputs guidance for the urea water time remaining.
