Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
In some embodiments, the method for prompting maintenance of an air cleaner provided by the embodiment of the present application may be applied to an application environment as shown in fig. 1. The vehicle-mounted terminal 102 may communicate with the server 104 directly or indirectly through a wired or wireless network, which is not limited in this embodiment of the present invention. The in-vehicle terminal 102 and the server 104 may cooperatively execute the maintenance prompting method for the air cleaner in the embodiment of the present application. One implementation process of the method for prompting maintenance of the air cleaner is executed by the cooperation of the in-vehicle terminal 102 and the server 104.
Specifically, the in-vehicle terminal 102 may acquire the current intake pressure at the intake port of the intake system during the running of the vehicle in real time. The vehicle-mounted terminal 102 sends the current intake pressure to the server 104, and the server 104 obtains the corresponding current blockage degree of the air filter under the condition of the current intake pressure according to the difference degree between the current intake pressure and the first calibrated intake pressure when the air filter is not blocked and the second calibrated intake pressure when the air filter is fully blocked; and predicting the corresponding residual running distance of the air filter when the current blockage degree reaches the full blockage according to the current blockage degree and the running distance of the vehicle when the current blockage degree is reached. The vehicle-mounted terminal 102 sends the current intake pressure to the server 104 in real time, and the server 104 updates the current blockage degree and the remaining driving distance in real time and carries out maintenance prompt based on the current blockage degree and the remaining driving distance. It is to be appreciated that the server 104 can be integrated in the cloud.
In which 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, or the like, or a server specially used for prompting maintenance of the air filter, which is not limited in this embodiment. 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 basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a Network service, cloud communication, a middleware service, a domain name service, a security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like.
In some embodiments, described in conjunction with the above-described operating environment, a service reminder for an air cleaner is provided, as shown in FIG. 2. Taking the example that the method is applied to a computer device (the computer device may specifically be the vehicle-mounted terminal or the server in fig. 1), the method includes the following steps:
step 202, acquiring the current intake pressure at an air inlet of an air intake system in the running process of the vehicle in real time.
The air intake system may be a turbocharging system or a natural air intake system, which is not particularly limited in the embodiments of the present application. Taking the air intake system as a turbocharger system as an example, the air inlet of the air intake system may be an air inlet of a turbocharger. In addition, the current intake pressure may be obtained by installing a sensor at the intake port of the turbocharger in real time.
And 204, acquiring the corresponding current blockage degree of the air filter under the condition of the forward air pressure according to the difference degree between the current air pressure and the first calibrated air pressure when the air filter is not blocked and the second calibrated air pressure when the air filter is fully blocked respectively.
The first calibration intake air pressure and the second calibration intake air pressure may be obtained by a vehicle calibration process, where vehicle calibration refers to detecting accuracy of a used instrument by using a standard measuring instrument. In the embodiment of the present application, the intake pressure of the intake port of the turbocharger at full load of the engine may be acquired as the first calibrated intake pressure by using a completely new air cleaner (i.e., an unclogged air cleaner). The intake pressure of the intake port of the turbocharger at the time of full load of the engine is acquired as the second calibrated intake pressure by using the air cleaner that is fully clogged. And the difference degree between the current air inlet pressure and the first calibrated air inlet pressure and the difference degree between the current air inlet pressure and the second calibrated air inlet pressure can reflect the service condition of the air filter, and the corresponding current blockage degree of the air filter can be obtained.
And step 206, predicting the corresponding residual running distance of the air filter when the current blockage degree reaches the full blockage according to the current blockage degree and the running distance of the vehicle when the current blockage degree is reached.
It will be appreciated that the current congestion level may be linearly related to the distance traveled by the vehicle. Therefore, the linear correlation coefficient between the blocking degree and the traveled distance can be calculated according to the current blocking degree and the traveled distance of the vehicle reaching the current blocking degree, the remaining unblocked degree from the current blocking degree to the full blocking degree is determined, and the product of the linear correlation coefficient and the unblocked degree can be used as the corresponding remaining traveled distance of the air filter reaching the full blocking from the current blocking degree. The clogging degree may be expressed by a percentage or a score, which is not specifically limited in the embodiment of the present application.
And step 208, updating the current congestion degree and the remaining driving distance in real time, and performing real-time maintenance prompt based on the current congestion degree and the remaining driving distance.
In consideration of the fact that a user may need to know the maintenance condition of the air filter in real time, the current blockage degree and the remaining driving distance can be updated in real time, and then corresponding maintenance prompt is carried out. The prompt mode may be that when the user drives the vehicle, the user performs a broadcast prompt through the vehicle-mounted terminal, which is not specifically limited in this embodiment of the application.
According to the maintenance prompting method of the air filter, the replacement period of the air filter is usually related to the dust concentration, and compared with the maintenance opportunity for determining the air filter based on the dust concentration calibration value, the maintenance prompting method of the air filter can avoid the fact that the dust concentration calibration value is different actually due to different environments and regions, and therefore maintenance prompting is inaccurate due to the fact that a unified 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 in the jam alarm and can only remind the user to change air cleaner under the complete circumstances of blockking up of air cleaner, through in time judging the opportunity that needs to change air cleaner and carry out the maintenance suggestion according to real-time current admission pressure to can avoid appearing leading to the problem that the oil consumption is high and the vehicle discharges not up to standard because of not changing air cleaner.
In some embodiments, obtaining a current intake pressure at an intake of an intake system of a vehicle during operation comprises:
acquiring a plurality of intake pressures acquired in each driving period aiming at a plurality of driving periods of the vehicle in the driving process; and selecting the minimum intake pressure from a plurality of intake pressures correspondingly acquired in each driving period, and selecting the minimum value from all the minimum intake pressures as the current intake pressure.
Specifically, the intake pressure at the intake port of the intake system may be monitored in real time by a pressure sensor during vehicle travel. For a series of intake pressures monitored, it is understood that the series of intake pressures are arranged in a time series. Thus, the whole monitoring process can be divided into a plurality of driving periods, and the intake pressure monitored in each driving period can be determined. For a certain driving period, a plurality of intake pressures in the driving period may be determined, and the minimum intake pressure Pn may be selected from them. Thus, a minimum intake pressure Pn can be generated for each driving session, and a plurality of driving sessions may form a series Pn. And selecting the minimum value from a series of Pn to obtain the current intake pressure. It should be noted that the intake pressure is usually a negative value, and the minimum intake pressure refers to the intake pressure with the largest absolute value.
In the above embodiment, the minimum intake pressure in a period of time can be selected, and the minimum intake pressure can possibly reflect the true blocking degree of the air filter in the period of time most, 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 the current blockage level of the air filter under the condition of the forward air pressure according to the difference degrees between the current intake pressure and a first calibrated intake pressure of the air filter when the air filter is unblocked and a second calibrated intake pressure of the air filter when the air filter is fully blocked respectively comprises:
calculating a first difference value 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 value 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 blockage degree according to the ratio of the first difference value to 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, ξ is the current blockage, Pnmin is the current intake pressure. It should be noted that the result obtained by calculating the above formula is a percentage, and in an actual implementation process, the result obtained by calculating the above formula may be multiplied by 100, so as to obtain a result in a score form, which is not specifically limited in this embodiment of the present application.
In the above embodiment, the first calibrated intake pressure and the second calibrated intake pressure may be respectively the intake upper limit value and the intake lower limit value of the air cleaner under the limit condition, so that the linear relationship of the intake pressure is obtained according to the upper limit value and the intake lower limit value, and the current blockage degree of the air cleaner can be accurately calculated.
In some embodiments, predicting a remaining travel distance of the air cleaner corresponding to the current clogging degree when the air cleaner is fully clogged, based on the current clogging degree and a travel distance of the vehicle when the current clogging degree is reached, includes:
acquiring the current non-blocking degree according to the current blocking degree; and calculating the ratio of the current non-jamming degree to the current jamming degree, and taking the product of the ratio and the traveled distance as the remaining traveled distance.
Specifically, the above calculation process may refer to the following formula (2):
in the above formula, L The residue is left Indicating the remaining driving distance, xi being the current degree of congestion, L Has already been used for Indicating the distance traveled. It should be noted thatTo be calculated by (100- ξ), primarily because ξ takes the current degree of obstruction in the form of a score.
In the above embodiment, since the remaining uncongested degree of the air cleaner 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 cleaner 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 service prompt based on the current congestion level and the remaining travel distance includes:
and pushing the current jam degree and the residual running distance to a display terminal, and displaying the current jam degree and the residual running distance through the display terminal.
It will be appreciated that the maintenance need may be prompted to the user in a variety of ways. In this application embodiment, can be through with present jam degree and surplus distance of traveling propelling movement to user terminal, rethread user terminal shows to the user can be according to present jam degree and surplus distance of traveling, knows again too much to be of a specified duration and needs to maintain air cleaner.
Above-mentioned embodiment, through to the present jam degree of display terminal propelling movement and surplus distance of traveling to show through display terminal, thereby can in time let the user know air cleaner's situation of use and subsequent maintenance opportunity, and then can avoid appearing leading to the problem that the oil consumption is high and the vehicle discharges not up to standard because of not changing air cleaner.
In some embodiments, obtaining the current degree of restriction of the air cleaner under the condition of the forward air pressure based on the degree of difference between the current intake air pressure and a first calibrated intake air pressure of the air cleaner when the air cleaner is not restricted and a second calibrated intake air pressure of the air cleaner when the air cleaner is fully restricted respectively further comprises:
judging whether the current air inlet pressure is smaller than a first calibrated air inlet pressure or not; and if the current intake pressure is smaller than the first calibrated intake pressure, acquiring the corresponding current blockage 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 when the air filter is not blocked and the second calibrated intake pressure when the air filter is fully blocked respectively.
Specifically, it can be seen from the above embodiment that the first calibrated intake air pressure is actually the intake air pressure measured when the air cleaner is not clogged. It is understood that the first calibrated intake air pressure is actually the maximum value of the intake air pressure in combination with the case where the intake air pressure is negative since the air cleaner is not clogged. As the degree of clogging of the air cleaner increases, the absolute value of the intake pressure only increases, and the intake pressure itself decreases. It is understood that the current intake pressure is at least less than the first calibrated intake pressure, indicating that the engine may be operating at full load, and that the present embodiment is also performing a maintenance evaluation under the assumption that the engine is operating at full load. Therefore, the current blocking degree is obtained when the current air inlet pressure is smaller than the first calibrated air inlet pressure, namely the engine is ensured to operate in a full-load state.
In the above embodiment, since the current congestion degree of the air cleaner can be obtained only when the current intake pressure is smaller than the first calibrated intake pressure, it can be ensured that the engine is subjected to maintenance evaluation in a full-load state, and the accuracy of the evaluation can be further improved.
For convenience of understanding, as shown in fig. 3, the method for prompting maintenance of an air cleaner according to the present application will now be described with reference to the foregoing embodiments, and includes the following steps:
step 302, aiming at a plurality of driving periods, selecting the minimum intake pressure from a plurality of intake pressures correspondingly collected in each driving period.
And step 304, selecting the minimum value from all the minimum intake pressures as the current intake pressure.
And 306, calculating a first difference value 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 value 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 acquiring the current blocking degree according to the ratio of the first difference value to the second difference value.
And 308, acquiring the current non-jamming degree according to the current jamming degree, calculating the ratio of the current non-jamming degree to the current jamming degree, and taking the product of the ratio and the distance traveled as the remaining travel distance.
And 310, pushing the current congestion degree and the remaining driving distance to a display terminal, and displaying the current congestion degree and the remaining driving distance through the display terminal.
In the above embodiment, since the replacement period of the air cleaner is usually related to the dust concentration, and compared with the maintenance opportunity for determining the air cleaner based on the dust concentration calibration value, the maintenance prompt is not accurate due to the fact that the dust concentration calibration values are actually different in different environments and regions, and thus, the maintenance prompt is inaccurate due to the adoption of the unified 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 in the jam alarm and can only remind the user to change air cleaner under the complete circumstances of blockking up of air cleaner, through in time judging the opportunity that needs to change air cleaner and carry out the maintenance suggestion according to real-time current admission pressure to can avoid appearing leading to the problem that the oil consumption is high and the vehicle discharges not up to standard because of not changing air cleaner.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the method, so specific limitations in the following embodiments of the maintenance prompting device for one or more air filters can be referred to the limitations on the maintenance prompting method for the air filter, and details are not described herein again.
