Problems solved by technology

[0002] The urea tank is a tank used to store urea solution. When adding urea solution to the urea tank, some impurities such as dust and stones are easy to enter the urea tank. If there are too many impurities in the urea tank, it may cause many failures Occurrence, such as urea tank liquid level sensor sticking, urea pump damage, etc.

Abstract

The invention provides a urea box cleaning early warning method, device and system and a medium, and the method comprises the steps: judging whether the concentration of a solution in a urea box is greater than or equal to a preset threshold value, if yes, presetting a cleaning early warning signal, and carrying out early warning according to the preset cleaning early warning signal. According to the method, extra equipment and cost do not need to be added, the impurity accumulation degree in the urea box can be judged through the existing urea box sensor, cleaning of the urea box can be reminded in time according to the concentration signal when the concentration is too large and abnormal, the phenomenon that the liquid level sensor of the urea box is stuck due to excessive impurities in the urea box is avoided, and the service life of the urea box is prolonged. And the service life of the urea box is prolonged, the change from post-maintenance to timely cleaning according to conditions is realized, and the maintenance cost is reduced.

Description

technical field [0001] The present application relates to the field of vehicle engineering, in particular to a method, device, system and medium for cleaning and early warning of a urea tank. Background technique [0002] The urea tank is a tank for storing urea solution. When adding urea solution to the urea tank, some impurities such as dust and stones can easily enter the urea tank. If there are too many impurities in the urea tank, it may cause many failures. Occurs, such as urea tank liquid level sensor stuck, urea pump damage and so on. [0003] Therefore, how to remind to clean the urea tank in time is a technical problem to be solved in this field. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of this application is to provide an early warning method, device, system and medium for cleaning the urea tank, which can prompt the cleaning of the urea tank in time and avoid the occurrence of failures. [0005] To achieve the above object, the applicati...
