Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In some embodiments, the maintenance prompting method of the air filter provided by the embodiment of the application can be applied to an application environment as shown in fig. 1. The vehicle terminal 102 may directly or indirectly communicate with the server 104 through a wired or wireless network, which is not limited in particular by the embodiment of the present application. The vehicle-mounted terminal 102 and the server 104 may cooperatively execute the maintenance prompting method of the air cleaner in the embodiment of the present application. One of the implementation procedures when the in-vehicle terminal 102 and the server 104 cooperatively execute the maintenance prompting method of the air cleaner will now be exemplified.
Specifically, the in-vehicle terminal 102 may acquire the current intake pressure at the intake port of the intake system of the vehicle during running in real time. The vehicle-mounted terminal 102 sends the current air inlet pressure to the server 104, and the server 104 obtains the corresponding current blocking degree of the air filter under the current air inlet pressure according to the difference degree between the current air inlet pressure and the first calibrated air inlet pressure of the air filter when the air filter is not blocked and the second calibrated air inlet pressure of the air filter when the air filter is fully blocked; and predicting the corresponding residual driving distance when the air filter is fully blocked by the current blocking degree according to the current blocking degree and the driving distance of the vehicle when the current blocking degree is reached. The in-vehicle terminal 102 transmits the current intake air pressure to the server 104 in real time, and the server 104 updates the current clogging degree and the remaining travel distance in real time and performs maintenance prompt based on the current clogging degree and the remaining travel distance. It is understood that the server 104 may be integrated in the cloud.
Wherein the in-vehicle terminal 102 may be mounted on a vehicle. The server 104 may be a background server corresponding to software, a web page, an applet, etc., or a server dedicated to performing maintenance prompt of the air cleaner, which is not limited in the embodiment of the present application. The server 104 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), basic cloud computing services such as big data and artificial intelligent platforms, and the like.
In some embodiments, in conjunction with the above description of the implementation, as shown in FIG. 2, a maintenance cue for the air cleaner is provided. Taking as an example that the method is applied to a computer device (the computer device may be a vehicle-mounted terminal or a server in fig. 1 specifically), the method includes the following steps:
step 202, acquiring the current air inlet pressure of an air inlet system of the vehicle in a running process in real time.
The air intake system may be a turbo-charging system or a natural air intake system, which is not particularly limited in the embodiment of the present application. Taking an intake system as an example of a turbocharger system, the intake port of the intake system may be an intake port of a turbocharger. In addition, the current intake air pressure may be obtained by mounting a sensor at the intake port of the turbocharger for real-time detection.
And 204, acquiring the corresponding current blockage degree of the air filter under the condition of the current air inlet pressure according to the difference degree between the current air inlet pressure and the first calibrated air inlet pressure of the air filter when the air filter is not blocked and the second calibrated air inlet pressure of the air filter when the air filter is fully blocked.
The first calibration air inlet pressure and the second calibration air inlet pressure can be obtained in a vehicle calibration process, and vehicle calibration refers to detection of accuracy of a used instrument by using a standard metering instrument. In the embodiment of the application, the air intake pressure of the air intake of the turbocharger at the full load of the engine can be obtained as the first calibrated air intake pressure by using a brand new air cleaner (i.e., an unplugged air cleaner). By using the fully blocked air cleaner, the intake pressure of the intake port of the turbocharger at the time of full load of the engine is obtained as the second nominal intake pressure. The difference degree between the current air inlet pressure and the first and second calibrated air inlet pressures can reflect the use condition of the air filter, and the corresponding current blocking degree of the air filter can be obtained.
And step 206, predicting the corresponding residual driving distance when the air filter is fully blocked by the current blocking degree according to the current blocking degree and the driving distance of the vehicle when the current blocking degree is reached.
It is understood that the current jam level may have a linear relationship with the distance traveled by the vehicle. Therefore, the linear correlation coefficient between the blockage degree and the driving distance can be calculated according to the current blockage degree and the driving distance of the vehicle when the current blockage degree is reached, the current blockage degree is determined to the left unblocked degree of full blockage, and the product of the linear correlation coefficient and the unblocked degree can be used as the corresponding residual driving distance when the air filter reaches full blockage from the current blockage degree. The blocking degree may be expressed in terms of a percentage, or may be expressed in terms of a score, which is not particularly limited in the embodiment of the present application.
And step 208, updating the current blocking degree and the residual driving distance in real time, and carrying out real-time maintenance prompt based on the current blocking degree and the residual driving distance.
Considering that a user may need to know the to-be-maintained condition of the air filter in real time, the current blocking degree and the residual driving distance can be updated in real time, and then corresponding maintenance prompt is carried out. The prompting mode may be that the vehicle-mounted terminal broadcasts the prompt when the user drives the vehicle, which is not particularly limited in the embodiment of the application.
According to the maintenance prompting method for the air filter, the replacement period of the air filter is generally related to the dust concentration, and compared with the maintenance time of determining the air filter based on the dust concentration calibration value, the maintenance prompting method can avoid the fact that the dust concentration calibration value is different in practice due to different environments and regions, so that the maintenance prompting is inaccurate due to the fact that the uniform dust concentration calibration value is adopted. In addition, the judgment is not needed to be carried out by combining the working condition of the engine, so that the judgment flow of the maintenance time can be simplified, and the treatment efficiency is improved. Finally, compare and only indicate the user and change air cleaner under the condition that air cleaner fully blocks up in the jam alarm, through in time judging the opportunity that needs to change air cleaner and carry out the maintenance suggestion according to real-time current air inlet pressure to can avoid appearing leading to the oil consumption high and the problem that the vehicle emission is not up to standard because of not changing air cleaner.
In some embodiments, obtaining a current intake pressure at an intake port of an intake system of a vehicle during operation includes:
acquiring a plurality of intake pressures acquired in each driving period for a plurality of driving periods during which the vehicle is driving; and selecting the minimum air inlet pressure from a plurality of air inlet pressures correspondingly acquired in each driving period, and selecting the minimum value from all the minimum air inlet pressures as the current air inlet pressure.
Specifically, the intake pressure at the intake port of the intake system may be monitored in real time by the pressure sensor during running of the vehicle. With respect to the series of intake pressures that are monitored, it is understood that the series of intake pressures are arranged in time series. Thus, the entire monitoring process can be divided into a plurality of travel periods, and the intake pressure monitored for each travel period can be determined. For a certain one of the travel periods, a plurality of intake pressures in the travel period may be determined, and the minimum intake pressure Pn may be selected therefrom. Thus, each travel period can generate a minimum intake pressure Pn, and a plurality of travel periods can form a series of Pn. The current intake pressure is obtained by selecting the minimum value from the series Pn. The intake pressure is usually a negative value, and the minimum intake pressure is the intake pressure with the largest absolute value.
In the above embodiment, since the minimum intake pressure in a period of time can be selected, the minimum intake pressure may most reflect the actual blocking degree of the air filter in the period of time, so that the time when the air filter needs to be replaced can be accurately determined, and accurate reminding can be performed.
In some embodiments, obtaining a corresponding current clogging degree of the air cleaner under the current intake pressure according to a degree of difference between the current intake pressure and a first calibrated intake pressure of the air cleaner when the air cleaner is not clogged and a second calibrated intake pressure of the air cleaner when the air cleaner is fully clogged, respectively, includes:
calculating a first difference between the current air inlet pressure and a first calibrated air inlet pressure of the air filter when the air filter is not blocked, and calculating a second difference between the current air inlet pressure and a second calibrated air inlet pressure of the air filter when the air filter is fully blocked; and obtaining the current blocking degree according to the ratio between the first difference value and the second difference value.
Specifically, the above calculation process may refer to the following formula (1):
in the above formula, P0 is the first calibrated intake pressure, P100 is the second calibrated intake pressure, ζ is the current clogging degree, and Pnmin is the current intake pressure. It should be noted that, the calculated result of the above formula is a percentage, and the calculated result may be multiplied by 100 in the actual implementation process, so as to obtain a result in a score form, which is not particularly limited in the embodiment of the present application.
In the above embodiment, since the first calibrated intake pressure and the second calibrated intake pressure are respectively the upper limit value and the lower limit value of the intake air of the air filter under the limit condition according to the first calibrated intake pressure and the second calibrated intake pressure, the current clogging degree of the air filter can be accurately calculated according to the linear relationship between the upper limit value and the upper limit value.
In some embodiments, predicting a corresponding remaining travel distance for the air cleaner from the current restriction to a full restriction based on the current restriction and the travel distance of the vehicle when the current restriction is reached, comprises:
obtaining the current unblocked degree according to the current blocked degree; and calculating the ratio between the current unblocking degree and the current blocking degree, and taking the product of the ratio and the travelled distance as the residual travelled distance.
Specifically, the above calculation process may refer to the following formula (2):
in the above formula, L The remainder is Indicating the residual driving distance, and xi is the current blocking degree, L Has already been provided with Indicating the distance travelled. It should be noted that the calculation is performed by (100- ζ), mainly because ζ is the current blockage level in the form of a score.
In the above embodiment, since the remaining uncongested degree of the air filter from the current congestion degree to the full congestion can be quantified by the difference between the constant and the current congestion degree, the corresponding remaining travel distance of the air filter from the current congestion degree to the full congestion can be accurately predicted according to the linear relationship between the current congestion degree and the travel distance of the vehicle.
In some embodiments, the maintenance prompt based on the current congestion level and the remaining distance travelled includes:
pushing the current blocking degree and the residual driving distance to the display terminal, and displaying the current blocking degree and the residual driving distance through the display terminal.
It will be appreciated that the maintenance requirements may be prompted to the user in a variety of ways. In the embodiment of the application, the current blocking degree and the residual running distance can be pushed to the user terminal, and then displayed through the user terminal, so that a user can know how much more maintenance needs to be performed on the air filter according to the current blocking degree and the residual running distance.
In the above embodiment, the current blocking degree and the remaining driving distance are pushed to the display terminal, and the current blocking degree and the remaining driving distance are displayed through the display terminal, so that a user can know the use condition of the air filter and the subsequent maintenance time in time, and further the problems that the oil consumption is high and the vehicle emission does not reach the standard due to the fact that the air filter is not replaced can be avoided.
In some embodiments, before obtaining the corresponding current clogging degree of the air filter under the condition of the current intake pressure according to the difference degrees between the current intake pressure and the first calibrated intake pressure of the air filter when the air filter is not clogged and the second calibrated intake pressure of the air filter when the air filter is fully clogged, the method further comprises:
judging whether the current air inlet pressure is smaller than the first calibrated air inlet pressure or not; and under the condition of being smaller than the preset air pressure, executing the step of acquiring the corresponding current blockage degree of the air filter under the condition of the current air pressure according to the difference degrees between the current air pressure and the first calibrated air pressure of the air filter when the air filter is not blocked and the second calibrated air pressure of the air filter when the air filter is fully blocked.
Specifically, from the above-described embodiments, it is known that the first nominal intake pressure is actually the intake pressure that is measured when the air cleaner is not clogged. It will be appreciated that the first nominal intake pressure is actually the maximum intake pressure, since the air cleaner is not plugged, in combination with the negative intake pressure. With the increasing degree of clogging of the air cleaner, the absolute value of the intake air pressure is only increased, and the intake air pressure itself is decreased. It will be appreciated that the current intake pressure only indicates that the engine may be operating at full load if it is at least less than the first calibrated intake pressure, and that embodiments of the present application also provide for maintenance evaluations under the assumption that the engine is operating at full load. Therefore, only when the current air inlet pressure is smaller than the first calibrated air inlet pressure, the engine is ensured to operate in a full-load state, and the current blocking degree is acquired.
In the above embodiment, the current congestion degree of the air filter may be obtained only when the current intake pressure is smaller than the first calibrated intake pressure, so that maintenance and evaluation of the engine in a full load state may be ensured, and further accuracy of the evaluation may be improved.
For easy understanding, as shown in fig. 3, a maintenance prompting method of the air cleaner according to the present application will be described with reference to the above embodiments, and includes the following steps:
step 302, selecting a minimum intake pressure from a plurality of intake pressures acquired correspondingly for each driving period for a plurality of driving periods.
And 304, selecting the minimum value from all the minimum air inlet pressures as the current air inlet pressure.
Step 306, calculating a first difference between the current air inlet pressure and a first calibrated air inlet pressure of the air filter when the air filter is not blocked, calculating a second difference between the current air inlet pressure and a second calibrated air inlet pressure of the air filter when the air filter is fully blocked, and obtaining the current blocking degree according to a ratio between the first difference and the second difference.
Step 308, according to the current blockage degree, obtaining the current unblocked degree, calculating the ratio between the current unblocked degree and the current blocked degree, and taking the product of the ratio and the travelled distance as the remaining travelling distance.
Step 310, pushing the current blocking degree and the residual driving distance to the display terminal, and displaying the current blocking degree and the residual driving distance through the display terminal.
In the above embodiment, since the replacement period of the air cleaner is also generally related to the dust concentration, it is possible to avoid the dust concentration calibration value from being actually different depending on the environment and region, and thus to avoid inaccurate maintenance prompts due to the adoption of the uniform dust concentration calibration value, compared to the determination of the maintenance timing of the air cleaner based on the dust concentration calibration value. In addition, the judgment is not needed to be carried out by combining the working condition of the engine, so that the judgment flow of the maintenance time can be simplified, and the treatment efficiency is improved. Finally, compare and only indicate the user and change air cleaner under the condition that air cleaner fully blocks up in the jam alarm, through in time judging the opportunity that needs to change air cleaner and carry out the maintenance suggestion according to real-time current air inlet pressure to can avoid appearing leading to the oil consumption high and the problem that the vehicle emission is not up to standard because of not changing air cleaner.

The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.

The implementation of the solution provided by the device is similar to that described in the above method, so the specific limitation in the embodiments of the maintenance prompting device for one or more air filters provided below may be referred to the limitation of the maintenance prompting method for an air filter hereinabove, and will not be repeated herein.
