In addition, in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.
Before introducing the method for reminding the replacement of the spark plug provided by the embodiment of the application, some concepts or technical terms mentioned in the embodiment of the application are first briefly described.
(1) Spark plug: is an important element in an engine ignition system that can introduce high voltage into the engine cylinder and cause it to jump over the electrode gap to create a spark that ignites the combustible mixture in the cylinder.

Further, based on the above explanation of the concept or technical term, the following briefly describes the design concept of the embodiment of the present application:
the spark plug is mainly used for igniting the mixed gas in the engine cylinder, so that the mixed gas is burnt in the engine cylinder to do work to provide power for the vehicle. The spark plug provides ignition energy through the high-voltage coil, so that high-energy spark is formed between the center electrode and the side electrode of the spark plug, and then mixed gas in the engine cylinder is ignited, and the aging and abrasion degree of the spark plug can directly influence the combustion state in the engine cylinder.
Spark plugs may fail or even fail due to wear, electrode erosion or deposit buildup, such as carbon build-up, so periodic replacement of the spark plugs is required when the vehicle is traveling for a period of time. Currently, strategies for replacing spark plugs: 1. the spark plug is replaced by maintaining the vehicle for a predetermined time. 2. Is replaced when the engine fails, such as when the engine is in fire, or replaced when the spark plug fails, such as when the spark plug cannot normally generate high-energy sparks so that the engine can normally operate.
When the spark plug is replaced according to the first strategy, the spark plug is still usable due to only slight abrasion, so that the resource waste is caused. When the spark plug is replaced according to the second strategy, the engine aftertreatment system may be damaged, for example, the mixed gas is insufficiently combusted in the cylinder and is discharged into the engine aftertreatment system to continue to combust, so that the temperature of the engine aftertreatment system is too high to cause damage, and the exhaust emission exceeds the standard.
In view of this, in order to better determine the replacement time of the spark plug, bring better use experience to the user, the embodiment of the application provides a method for reminding the replacement of the spark plug, which specifically includes: firstly, obtaining actual use mileage of a spark plug; calculating the usable mileage of the spark plug according to the current spark plug gap value change curve and the spark plug gap threshold value of the spark plug, wherein the spark plug gap value change curve represents the corresponding relation between the spark plug gap value and the usable mileage; further judging whether the actual use mileage of the spark plug is greater than the usable mileage of the spark plug; if yes, sending out a spark plug replacement reminding message; if not, the current use state of the spark plug is maintained.
Referring to fig. 1, an optional application scenario schematic diagram provided in an embodiment of the present application is shown, where the application scenario includes: server and vehicle. The server and the vehicle can perform information interaction through a communication network, wherein the communication mode adopted by the communication network can comprise: wireless communication and wired communication.

Alternatively, the server may access the network by short-range wireless communication to communicate with the vehicle. Among these short-range wireless communication modes, for example, include wireless fidelity (Wireless Fidelity, wi-Fi) technology.
The number of communication devices involved in the system architecture is not limited, for example, more servers may be included, or other network devices may be further included, as shown in fig. 1, and only the servers and the vehicle are taken as examples to describe the above devices and their respective functions, which are briefly described below.

The vehicle may be any vehicle having an engine and a spark plug, for example, a vehicle using gasoline or the like as a fuel or a vehicle using natural gas, methanol or the like as a fuel.
Specifically, in the embodiment of the present application, the server is configured to obtain an actual use mileage of the spark plug; calculating the usable mileage of the spark plug according to the current spark plug gap value change curve and the spark plug gap threshold value of the spark plug, wherein the spark plug gap value change curve represents the corresponding relation between the spark plug gap value and the usable mileage; further judging whether the actual use mileage of the spark plug is greater than the usable mileage of the spark plug; if yes, sending out a spark plug replacement reminding message; if not, the current use state of the spark plug is maintained.
Based on the method, the usable mileage of the spark plug is predicted through the spark plug gap value change curve of the spark plug, so that a user can be timely reminded of replacing the spark plug when the actual usable mileage of the spark plug is close to the usable mileage of the spark plug, and the user experience is improved.
The following describes a method for reminding replacement of a spark plug according to an embodiment of the present application with reference to the above system architecture and the accompanying drawings.
Referring to fig. 2, a flowchart of a method for reminding replacement of a spark plug according to an embodiment of the present application is shown, and a specific implementation flow of the method is as follows:
s21, acquiring actual use mileage of the spark plug;
in the embodiment of the application, the actual use mileage of the spark plug can be obtained by reading data in the engine by an electronic control unit (Electronic Control Unit, ECU) in the vehicle. The ECU, after reading the data in the engine, transmits the actual mileage of the ignition plug to the server.
S22, calculating the usable mileage of the spark plug according to the current spark plug gap value change curve and the spark plug gap threshold value of the spark plug;
in an alternative embodiment, the target ignition energy value of the target cylinder is first obtained under a preset operating condition. It should be noted that the target cylinder is a cylinder of a target ignition energy value to be measured, for example, the engine of the current vehicle is a four-cylinder engine, and thus, the target cylinder may be one cylinder of one cylinder, two cylinders, three cylinders, or four cylinders. Each cylinder needs to be detected separately when the target ignition energy value of the target cylinder is acquired. The target ignition energy value is the minimum ignition energy value required for the spark plug to ignite the mixture in the engine.
In the embodiment of the present application, when the target ignition energy value of the target cylinder is acquired, the engine is first set to the check spark plug gap mode. At this time, it is necessary to keep the engine running under a stable condition.
Specifically, the engine speed is set to a preset speed, such as 2000 rpm, 3000 rpm, or other stable speeds that enable the engine to run smoothly, the embodiment of the present application is not limited herein specifically, the vehicle in which the engine is located is set to N gear (neutral gear), the throttle valve and the ignition advance angle of the engine are set to preset parameters, the engine is not failed, and the target cylinder is in an unfired state. Setting the engine to a preset operating condition can obtain a more accurate and stable target ignition energy value.
In an alternative embodiment, the method for acquiring the target ignition energy value of the target cylinder under the preset working condition comprises the following steps:
firstly, acquiring the current ignition energy value of a target cylinder under a preset working condition. Specifically, the current ignition energy value of the target cylinder is specifically an ignition energy value generated by the ignition plug igniting the mixed gas in the target cylinder in the current engine operating state, such as 40 millijoules. The current ignition energy value is larger than the target ignition energy value.
Further, the current ignition energy value is successively reduced according to the preset value until the engine is in a misfire condition. Specifically, for example, the preset value is set to be 1 millijoule, the current ignition energy value is reduced by 1 millijoule each time according to the preset value, the engine is ignited after the current ignition energy value is reduced, whether the engine can successfully ignite under the condition of the current ignition energy value is judged, if the engine can successfully ignite, the current ignition energy value is continuously reduced according to the preset value, and if the engine can not successfully ignite, the current ignition energy value when the engine is in a fire state is obtained. The specific preset value is determined according to the actual application scenario, and is not specifically limited herein.
The current ignition energy value when the engine is in a misfire condition is taken as a target ignition energy value, for example, the current ignition energy value is successively reduced until the value is reduced by 35 mJ, and then 35 mJ is taken as the target ignition energy value when the engine is in the misfire condition.
By the method, the target ignition energy value is obtained under the preset working condition, and the accuracy of the current spark plug gap value obtained through the target ignition energy value can be ensured, so that the usable mileage of the spark plug can be accurately predicted.
In an alternative embodiment, the current spark plug gap value of the spark plug may be calculated from the spark plug breakdown voltage value and the target ignition energy value.
First, the breakdown voltage value of the spark plug at the time of ignition of the engine and the target ignition energy value are obtained by the ECU in the vehicle, for example, the breakdown voltage value of the spark plug at the current operating condition is 7000V and the target ignition energy value is 35 joules are obtained by the ECU.
Further, dividing the target ignition energy value by the breakdown voltage value yields a first value, such as 7000V divided by 35 joules, yielding a first value of 200, and then taking the multiple of the first value as the current spark plug gap value for the spark plug.
In the above alternative embodiment, the current spark plug gap value of the above spark plug may be obtained by the following calculation formula:
Figure BDA0004150973780000091
wherein G is gap For the gap distance between the central electrode and the side electrode of the spark plug, i.e. the spark plug gap value, V bd For breakdown voltage of spark plug, E bd The minimum energy value required for successful ignition of the spark plug, i.e., the target ignition energy value.
Further, after the current gap value of the spark plug is obtained, fitting the current spark plug gap value of the spark plug with points in a historical spark plug gap value change curve of the spark plug to obtain the current gap value change curve of the spark plug.
Specifically, in the embodiment of the present application, detecting the use condition of the spark plug is performed in accordance with a prescribed mileage. For example, the spark plugs are tested at a frequency of once every 10000 km, so that a current spark plug gap value of one spark plug, such as 0.3mm, is possible at 10000 km. As shown in fig. 3, the use mileage of the spark plug is set as the abscissa and the current spark plug gap value of the spark plug is set as the ordinate, whereby a smooth curve can be generated in the coordinate system, and whereby the curve can be a function of the correspondence between the spark plug gap value and the use mileage.
Further, according to the detection frequency at 20000 km, the current spark plug gap value of a spark plug can be obtained, so that a corresponding coordinate can be obtained, and the coordinate obtained at 20000 km is fitted with the coordinate obtained at 10000 km, so that an approximately linear smooth curve can be obtained. In the process, the change state of the gap value of the spark plug is more and more stable along with the increase of the use mileage, so that the obtained curve can more accurately predict the current use mileage of the spark plug.
It will be appreciated that the spark plug is tested according to the specified mileage, a smooth curve that is approximately linear is obtained by fitting the actual mileage used at each test and the spark plug clearance value to points in the historical spark plug clearance value change curve, a function of the spark plug clearance value and the actual mileage used is obtained from the curve, and the usable mileage of the spark plug can be predicted by substituting the spark plug clearance threshold value into the function. With the increase of fitting times, the function can be understood to be optimized, so that the available mileage of the spark plug obtained according to the spark plug gap threshold value of the spark plug is more accurate.
S23, judging whether the actual use mileage of the spark plug is greater than the usable mileage of the spark plug;
the step S22 is used for predicting the available mileage of the spark plug when the different available mileage of the spark plug is used, then comparing the actual available mileage with the predicted available mileage, and if the actual available mileage of the spark plug is larger than the predicted available mileage, then turning to the step S24. If the actual mileage of the spark plug is less than the predicted usable mileage, the process proceeds to step S25.
By the method, a user can be timely reminded of replacing the spark plug, potential safety hazards are eliminated, and reliable operation of the engine is ensured.
S24, sending out a spark plug replacement reminding message;
specifically, the usable mileage of the spark plug is predicted by the spark plug gap value change curve, and then the predicted usable mileage of the spark plug is compared with the current actual usable mileage. The spark plug is excessively worn to cause the excessive spark plug gap value, so that the available mileage of the spark plug is shortened, for example, the current actual use mileage is 50000 km, and the predicted available mileage is less than the current actual use mileage due to the reason, so that the server sends a spark plug replacement reminding message to the user. In the embodiment of the application, the server may display the spark plug replacement reminding message through the central control screen, or display the spark plug replacement reminding message on the dashboard, or display the spark plug replacement reminding message in other alternative manners, which is not limited in detail herein.
S25, maintaining the current use state of the spark plug.
If the running state of the engine is good and the abrasion to the spark plug is small in the using process of the vehicle, the predicted usable mileage of the spark plug according to the change curve of the gap value of the spark plug is larger than the actual usable mileage of the spark plug at the moment, the condition that the use of the spark plug does not reach the upper limit is indicated, and the current use state of the spark plug can be kept for use.
It should be noted that, when the engine includes a plurality of cylinders, the detection process of the service condition of the spark plug in each cylinder is consistent with that described in the steps in the embodiments of the present application, when the engine includes a plurality of cylinders, the service condition of the spark plug corresponding to one cylinder may be detected, and then the service data of the spark plug corresponding to the cylinder may be returned to the server, or the service data of all the spark plugs may be returned to the server after the service conditions corresponding to the spark plugs in all the cylinders are detected. When the spark plug needs to be replaced, the server can specifically inform the user of the spark plug needing to be replaced, so that maintenance personnel can save the process of disassembling and assembling the spark plug to judge whether the spark plug needs to be replaced.
Based on the method, the accumulated detection of the gap value of the spark plug is used for generating a change curve of the gap value of the spark plug, so that the quantification of the gap value of the spark plug is realized, a user can be reminded of replacing the spark plug at a proper time, potential safety risks are eliminated, the engine can stably run, and meanwhile, the resource waste caused by replacing the spark plug when the spark plug does not reach the upper use limit is avoided.
