Abstract: A method of notifying an operator that a reductant tank associated with a machine is in a full state during filling of the reductant tank. The method includes receiving a signal indicative of a current level of the reductant within the reductant tank from an electronic control module of the machine. The method also includes comparing the current level of the reductant with a predetermined threshold. The method further includes determining if a full tank status of the reductant tank exists corresponding to the current level of the reductant being greater than the predetermined threshold. The method further includes triggering a notification based on the determination of the full tank status condition of the reductant tank. The notification is provided in such a manner to alert an operator positioned outside of the machine of the full tank status of the reductant tank.

Abstract translation: 通知操作者在与还原剂罐的填充期间，与机器相关联的还原剂槽处于完全状态的方法。 该方法包括从机器的电子控制模块接收指示还原剂箱内的还原剂的当前水平的信号。 该方法还包括将还原剂的当前水平与预定阈值进行比较。 该方法还包括确定是否存在与还原剂的当前水平大于预定阈值相对应的还原剂罐的满罐状态。 该方法还包括基于确定还原剂罐的满罐状态来触发通知。 提供通知以这样一种方式来提醒位于机器外部的操作者处于还原剂箱的满罐状态。
