For a better understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Exemplary method
Referring to fig. 1, the flowchart of a method for early warning of cleaning of a urea tank according to an embodiment of the present application includes:
s101: and judging whether the concentration of the solution in the urea box is greater than or equal to a preset threshold value.
In the embodiment of the application, when the impurities in the urea box are more, the concentration of the solution in the urea box is larger, so that whether the impurities in the urea box are excessive can be judged according to the concentration of the solution in the urea box.
Specifically, the urea tank sensor can be used for detecting the concentration of the urea solution in the urea tank, the urea tank sensor measures the concentration of the urea solution according to the difference of the propagation speed of ultrasonic waves in the urea solutions with different concentrations, and when impurities in the urea solution are excessive, the measured value of the concentration probe is larger.
It should be noted that, in the embodiment of the present application, the size of the preset threshold is not particularly limited, and may be set by a person skilled in the art according to actual situations.
In a possible implementation manner, before judging whether the concentration of the solution in the urea tank is greater than a preset threshold, whether the state of the urea pump is in a reverse pumping state or not is judged, and if so, whether the concentration of the solution in the urea tank is greater than the preset threshold is judged.
The reverse pumping state of the urea pump refers to a state that the urea pump is adopted to reversely pump the urea solution in the urea pipeline, the urea pump and the urea nozzle back to the urea tank when the vehicle is in a power-off state.
When the driver adds the urea solution for the urea case, impurity such as some dusts, pebbles enter into the urea case easily, and under the action of gravity, these impurity can deposit in urea bottom of the case portion, when the urea pump begins to pour and takes out, urea solution that gushes out in urea case pipette mouth can break away the impurity of bottom, distributes around concentration probe, leads to concentration measurement value bigger than normal to the concentration that obtains the urea solution that can be more accurate.
This application embodiment utilizes urea case sensor to detect the urea solution concentration that obtains in the urea case when the urea pump is in the state of drawing backward, avoids impurity deposit in urea bottom of the case portion and the urea case sensor that leads to detect the urea solution concentration that obtains in the urea case little to do not carry out the washing of urea case, lead to when the operation impurity too much and the urea case level sensor jamming that leads to, faults such as urea pump damage take place.
In a possible implementation manner, before judging whether the concentration of the solution in the urea tank is greater than a preset threshold, judging whether the liquid level of the solution in the urea tank is below a set limit value, and if so, judging whether the concentration of the solution in the urea tank is greater than the preset threshold.
That is, in the embodiment of the present application, for economic reasons, when the urea solution in the urea tank is large, if the urea tank is cleaned at this time, the urea solution in the urea tank needs to be emptied, which results in large waste of the urea solution and high cost.
Therefore, in order to save cost, the urea tank can be cleaned when the liquid level of the solution in the urea tank is below the set limit value, so that the waste of the urea solution can be reduced, and the cost is saved. Specifically, in the embodiments of the present application, the size of the setting restriction may be set by a person skilled in the art according to actual situations, and the embodiments of the present application are not specifically limited herein.
S102: if the number is larger than or equal to the preset number, a cleaning early warning signal is preset.
In the embodiment of the application, when the concentration of the solution in the urea tank is greater than or equal to the preset threshold value, a cleaning early warning signal can be preset, so that early warning can be performed according to the cleaning early warning signal in the following process, and the urea tank is cleaned.
Because the solution concentration in the urea box can be monitored in real time, when the solution concentration in the urea box is detected to be larger than or equal to a preset threshold value, a vehicle is probably running, or the vehicle is in other states which are inconvenient to clean the urea box, and the urea box is not required to be cleaned at once at this moment, therefore, a preset cleaning early warning signal can be established firstly, and when the vehicle is in a state which can clean the urea box, the urea box is cleaned, so that the vehicle can run in a good state, and the fault is prevented.
Optionally, the preset cleaning early warning signal can be displayed to a user, so that the user can clean the urea box in time.
S103: and carrying out early warning according to the preset cleaning early warning signal.
In this application embodiment, can carry out the early warning according to predetermineeing and wash early warning signal to in time wash the urea case, avoid because of urea case level sensor jamming that impurity in the urea case too much leads to, trouble such as urea pump damage takes place, has prolonged the life of urea case, has realized engaging in the after maintenance to the timely abluent conversion of according to the situation, has reduced cost of maintenance.
In one possible implementation, different early warning modes can be adopted according to different states of the vehicle.
The utility model provides a mode can be according to predetermineeing and wash early warning signal, when the vehicle is electrified, adopts the vehicle to carry out the early warning from the storage battery of taking, and this kind of mode need not the vehicle and goes up the electricity and can carry out the early warning, has further improved the promptness of early warning to in order can in time carry out the washing of urea case, avoid the emergence of trouble.
The other mode can be according to predetermineeing and wash the early warning signal, early warning when the vehicle is electrified, need not to consume the electric quantity of vehicle from taking the storage battery like this, optionally, because after the vehicle is electrified, urea solution may have been added in the urea case again, consequently can further judge the liquid level of urea case when the vehicle is electrified, if the solution liquid level of urea case is less than or equal to when setting for the limit value, just carry out the early warning, avoid leading to emptying of urea case solution because of wasing the urea case, avoid extravagant.
The embodiment of the application provides a urea box cleaning early warning method, which comprises the following steps: and judging whether the concentration of the solution in the urea tank is greater than or equal to a preset threshold value, if so, presetting a cleaning early warning signal, and carrying out early warning according to the preset cleaning early warning signal. This application need not to increase extra equipment and cost promptly, can judge the impurity accumulative degree in the urea case through current urea case sensor, according to concentration signal, when concentration is unusual greatly, can in time remind the washing urea case, avoid because of the urea case level sensor jamming that the impurity in the urea case leads to, trouble such as urea pump damage takes place, the life of urea case has been prolonged, realized engaging in the after-maintenance to the timely abluent conversion of contingency, maintenance cost has been reduced.
