The invention relates to the technical field of automobile detection, in particular to a urea liquid level warning method and computer equipment. The urea liquid level warning method is applied to an automobile ECU, and the urea liquid level warning method comprises the steps: acquiring the vehicle slope information; determining the liquid level correction information according to the vehicle gradient information; obtaining a urea liquid level value according to the urea liquid level measurement value and the liquid level correction information; and judging whether to give an alarm or not according to the urea liquid level value. The method has the advantages that the influence of gradient information on the urea liquid level numerical value is reduced, the urea liquid level numerical value is not prone to large-range fluctuation, and false alarm caused by the fact that the urea liquid level numerical value fluctuates to be too low is avoided.

    本申请涉及汽车检测技术领域,特别涉及一种尿素液位告警方法及计算机设备,所述尿素液位告警方法,应用于汽车ECU,其包括:获取车辆坡度信息;根据所述车辆坡度信息确定液位修正信息;根据尿素液位测量数值和所述液位修正信息得到尿素液位数值;根据所述尿素液位数值判断是否告警。本申请具有减小尿素液位数值受到坡度信息的影响,尿素液位数值不易大范围波动,避免了由于尿素液位数值波动至过低而误告警的优点。
