摘要： A work vehicle includes a cooling fan that selectively and/or periodically runs in reverse in order to discharge accumulated dirt or debris from one or more coolers. The reverse activation of the fan is prevented from initiating when the operator of the running vehicle is outside the operator cab in the vicinity of the coolers. In an exemplary embodiment, activation of a parking brake interrupts or prevents reverse activation of the fan, though a fuel door sensor may also be used. A minimum engine speed may be specified to ensure adequate power for maximum fan power during the reverse operation.

摘要： A method of controlling a work vehicle on a worksite. Receiving a weather data indicative of a rainfall of the worksite. Receiving a design topography data indicative of the worksite in a final configuration. Receiving a current topography data. Determining a low elevation location on the worksite that may accumulate water from the rainfall. Comparing the rainfall to a rainfall threshold. Devising a temporary design topography data and communicating the temporary design topography data to the work vehicle if the rainfall threshold is met.
