Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and specifically to a method, device, vehicle and storage medium for detecting and controlling water accumulation in an engine. Background Art

[0002] Oil emulsification is a phenomenon that occurs when the amount of water accumulated in the engine increases. The main reason for the oil emulsification phenomenon is that as the vehicle engine runs, the fuel in the engine cylinder will produce relatively more water after combustion; the water produced by the fuel combustion will flow into the engine crankcase through the gap between the piston and the cylinder liner, the piston ring opening, the gap between the piston ring and the cylinder liner, etc. When the amount of water accumulated in the engine crankcase (the amount of water accumulated in the engine) reaches a certain amount, the oil will emulsify.

[0003] Currently, there are many factors that affect the amount of water accumulated in the engine when the vehicle is running. However, the accuracy of the existing technology for detecting the amount of water accumulated in the engine is low, which affects the detection result of the amount of water accumulated in the engine, and then affects the engine's water removal operation, ultimately causing the engine oil to emulsify.

[0004] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Summary of the invention

[0005] In view of this, the present application provides a method, device, vehicle and storage medium for detecting and controlling the amount of water accumulated in an engine, so as to help solve the problem of low detection accuracy of the amount of water accumulated in the engine, which in turn affects the engine's water removal operation and ultimately causes engine oil emulsification.

[0006] In a first aspect, an embodiment of the present application provides a method for detecting water accumulation in an engine, the method comprising:

[0007] Determining a water production rate of the engine according to a current operating environment of the engine;

[0008] The amount of water accumulated in the engine is determined according to the water production rate and the current running time of the engine.

[0009] In the embodiment of the present application, the water production rate of the engine is first determined according to the current operating environment of the engine; then the amount of water accumulated in the engine is determined according to the water production rate and the current operating time of the engine. It can be understood that based on the water production rate and the current operating time of the engine, a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched water removal operation, thus avoiding the phenomenon of engine oil emulsification to a certain extent.

[0010] In a possible implementation, determining the water production rate of the engine according to the current operating environment of the engine includes:

[0011] The water production rate of the engine is determined according to the current oil temperature of the engine, the current ambient temperature and the current engine speed.

[0012] In an embodiment of the present application, based on the current oil temperature of the engine, the current ambient temperature and the current engine speed, a more accurate water production rate of the engine can be determined, and then a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched water removal operation, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0014] Obtaining an initial amount of water accumulated in the engine;

[0015] Determining the newly accumulated water volume of the engine according to the water production rate and the current running time of the engine;

[0016] The amount of water accumulated in the engine is determined according to the initial amount of water accumulated and the newly added amount of water accumulated.

[0017] Among them, the initial water accumulation of the engine refers to the water accumulation before the engine starts to calculate the water production rate; the water production rate of the engine is used to indicate the rate at which water is produced when the engine is running, and the current running time of the engine refers to a certain period of time when the engine is running.

[0018] In the embodiment of the present application, the initial water accumulation of the engine is first obtained; then the newly added water accumulation of the engine is determined according to the water production rate and the current running time of the engine; finally, the water accumulation of the engine is determined according to the initial water accumulation and the newly added water accumulation. It can be understood that a more accurate water accumulation of the engine can be determined according to the initial water accumulation and the newly added water accumulation; based on the more accurate water accumulation of the engine, the engine can perform a more matched water removal operation, avoiding the emulsification of the engine oil to a certain extent.

[0019] In a possible implementation, determining the newly accumulated water volume of the engine according to the water production rate and the current running time of the engine includes:

[0020] The water production rate and the current running time of the engine are integrated to determine the newly accumulated water volume of the engine.

[0021] In the embodiment of the present application, the water production rate and the current running time of the engine are integrated to more quickly and accurately determine the newly accumulated water volume of the engine, thereby improving the water removal rate of the engine.

[0025] When the amount of water accumulated in the engine is greater than the water accumulation threshold, a water removal operation of the engine is performed to reduce the amount of water accumulated in the engine.

[0026] In an embodiment of the present application, the amount of water accumulated in the engine is first determined; then, based on the amount of water accumulated in the engine, it is determined whether the amount of water accumulated in the engine is greater than a water accumulation threshold; when the amount of water accumulated in the engine is greater than the water accumulation threshold, an engine water removal operation is performed to reduce the amount of water accumulated in the engine, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0027] In a possible implementation, the method further includes:

[0028] When the amount of water accumulated in the engine is less than or equal to a water accumulation threshold, the amount of water accumulated in the engine is re-determined.

It can be understood that monitoring the amount of water accumulated in the engine when the engine is working can ensure that when the amount of water accumulated in the engine is greater than the water accumulation threshold, the engine is promptly controlled to perform a water removal operation (i.e., perform an engine water removal operation) to reduce the amount of water accumulated in the engine, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0030] In a possible implementation, when the amount of water accumulated in the engine is greater than the water accumulation threshold, performing an engine water removal operation includes:

[0031] When the amount of water accumulated in the engine is greater than the water accumulation threshold, determining a water removal requirement level according to the amount of water accumulated in the engine;

[0032] According to the water removal requirement level, performing a water removal operation of the engine that matches the water removal requirement level;

[0033] The level value of the water removal requirement level is positively correlated with the water removal rate of the water removal operation of the engine.

[0034] In the embodiment of the present application, when the amount of water accumulated in the engine is greater than the water accumulation threshold, the dewatering requirement level is first determined according to the amount of water accumulated in the engine; then, according to the dewatering requirement level, a dewatering operation of the engine matching the dewatering requirement level is performed. It can be understood that by determining dewatering operations corresponding to different dewatering requirement levels based on different amounts of water accumulated in the engine, the engine can perform a more matching dewatering operation, thereby improving the dewatering rate of the engine to a certain extent.

[0039] The water removal rate of the engine is used to indicate the rate at which water is removed when the engine is running.

[0040] In the embodiment of the present application, the engine water removal rate is first determined; then the engine water removal amount is determined based on the water removal rate and the current engine water removal time; finally, based on the engine water accumulation amount and the engine water removal amount, it is determined whether to stop the engine water removal operation. It can be understood that based on the engine water accumulation amount and the engine water removal amount, the engine water removal operation can be more accurately controlled to stop, which improves the engine water removal rate to a certain extent.

[0041] In a possible implementation, determining the amount of water removed from the engine according to the water removal rate and the current water removal time of the engine includes:

[0042] Integrating the water removal rate and the current water removal time of the engine to determine the water removal amount of the engine;

[0043] The current water removal time of the engine refers to a certain period of time when the water removal operation of the engine is performed.

[0046] Subtracting the amount of water accumulated in the engine from the amount of water removed to determine the remaining amount of water accumulated in the engine;

[0047] When the remaining water accumulation amount of the engine is less than or equal to the water accumulation amount threshold, the water removal operation of the engine is stopped.

[0048] In an embodiment of the present application, a subtraction operation is performed between the amount of water accumulated in the engine and the amount of water removed, thereby more quickly and accurately determining the remaining amount of water accumulated in the engine, thereby improving the water removal rate of the engine to a certain extent.

[0086] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0087] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0089] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0090] Oil emulsification is a phenomenon that occurs when the amount of water accumulated in the engine increases. The main reason for the oil emulsification phenomenon is that as the vehicle engine runs, the fuel in the engine cylinder will produce relatively more water after combustion; the water produced by the fuel combustion will flow into the engine crankcase through the gap between the piston and the cylinder liner, the piston ring opening, the gap between the piston ring and the cylinder liner, etc. When the amount of water accumulated in the engine crankcase (the amount of water accumulated in the engine) reaches a certain amount, the oil will emulsify. For ease of understanding, the specific application scenarios are first illustrated below.

[0091] See also Figure 1 , is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, the application scenario includes: a vehicle 101, wherein the vehicle 101 includes an engine. The vehicle 101 is also equipped with an electronic control unit (ECU). Specifically, when it is detected that the amount of water accumulated in the engine reaches a certain amount, the ECU promptly controls the engine to perform an engine water removal operation to avoid the occurrence of oil emulsification.

[0092] It can be understood that the engine water removal operation described above is the operation of removing the accumulated water in the engine crankcase. For the sake of brevity, this application will not elaborate on it here.

[0093] in addition, Figure 1 The vehicle 101 shown in the figure is only an exemplary description and should not be used as a limitation on the scope of protection of the present application. Of course, the present application does not specifically limit the type of engine. For example, the engine includes but is not limited to the engine of a hybrid vehicle, the engine of a traditional pure fuel vehicle, etc.

[0094] In the prior art, the detection accuracy of the amount of water accumulated in the engine is low, which in turn affects the engine's water removal operation and ultimately causes the engine oil to emulsify.

[0095] In response to the above problems, in an embodiment of the present application, the water production rate of the engine is first determined according to the current operating environment of the engine; then, the amount of water accumulated in the engine is determined according to the water production rate and the current operating time of the engine. It can be understood that based on the water production rate and the current operating time of the engine, a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched water removal operation, thereby avoiding the phenomenon of engine oil emulsification to a certain extent. Specifically, a detailed description is given below in conjunction with the accompanying drawings and specific embodiments. See. Figure 2 , is a flow chart of a method for detecting the amount of water accumulated in an engine provided in an embodiment of the present application. The method can be applied to Figure 1 In the application scenario shown, Figure 2 As shown, it mainly includes the following steps.

[0096] Step S201: Determine the water production rate of the engine according to the current operating environment of the engine.

[0097] In practical applications, the oil water content sensor is first used to detect the water production of the engine under different operating environments, and then the water production rate of the engine under different operating environments is determined; then the current operating environment of the engine is obtained; finally, the water production rate of the engine is determined based on the current operating environment of the engine.

[0098] Exemplarily, the relationship between the operating environment of the engine and the water production rate is shown in Table 1. It can be understood that when the current operating environment of the engine is operating environment A, the water production rate of the engine is determined to be water production rate A; similarly, when the current operating environment of the engine is operating environment B, the water production rate of the engine is determined to be water production rate B; similarly, when the current operating environment of the engine is operating environment C, the water production rate of the engine is determined to be water production rate A; and so on, and the embodiments of the present application will not be repeated here.

[0099] Table 1:

[0100] Engine operating environment Water production rate Operating Environment A Water production rate A Operating Environment B Water production rate B Operating Environment C Water production rate A Operating Environment D Water production rate C Operating Environment Water production rate D

[0101] It should be pointed out that the above table is only an exemplary description of the correspondence between the operating environment of the engine and the water production rate. In practical applications, those skilled in the art may set other correspondences between the operating environment of the engine and the water production rate, for example, a correspondence curve between the operating environment of the engine and the water production rate or a correspondence model between the operating environment of the engine and the water production rate.

[0102] It should be noted that the current operating environment of the engine described above is generally used to represent the internal and external working environment of the engine when the engine is in working state. It is understandable that the current operating environment of the engine includes: the fuel type of the engine (for example: No. 92 gasoline or No. 95 gasoline, etc.), the current oil temperature of the engine, the current ambient temperature and the current engine speed, etc. Of course, the current operating environment of the engine also includes other aspects, which are not specifically limited in this application.

[0103] In a possible implementation, the water production rate of the engine can be determined according to the current engine oil temperature, the current ambient temperature and the current engine speed. It is understandable that a more accurate water production rate of the engine can be determined according to the current engine oil temperature, the current ambient temperature and the current engine speed, and then a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched water removal operation, and to a certain extent avoid the phenomenon of engine oil emulsification.

[0104] Step S202: Determine the amount of water accumulated in the engine according to the water production rate and the current running time of the engine.

[0105] In the embodiment of the present application, after the water production rate is determined, the amount of water accumulated in the engine is determined based on the water production rate and the current running time of the engine. The current running time of the engine generally refers to the time period from when the engine is started to the current moment. For example, if the engine is started at moment t1, then when it runs to the current moment t2, the current running time of the engine is t2-t1.

[0106] It should be pointed out that the amount of water accumulated in the engine includes not only the amount of new water accumulated in the engine during the current running time of the engine, but also the initial amount of water accumulated in the engine before the current running time.

[0107] Therefore, in practical applications, in order to determine the amount of water accumulated in the engine more accurately, in one possible implementation method, an initial amount of water accumulated in the engine can be preset; then, the amount of additional water accumulated in the engine is determined based on the water production rate and the current running time of the engine; finally, the amount of water accumulated in the engine is determined by adding the amount of additional water accumulated in the engine to the initial amount of water accumulated in the engine.

[0108] Exemplarily, the preset initial water accumulation amount of the engine is the initial water accumulation amount A of the engine. Specifically, the newly added water accumulation amount of the engine is determined according to the water production rate and the current running time of the engine; then the newly added water accumulation amount of the engine is added to the initial water accumulation amount A of the engine to determine the water accumulation amount of the engine.

[0109] However, in actual applications, the initial amount of water accumulated in the engine is usually not fixed, so a method of presetting the initial amount of water accumulated in the engine makes the determined amount of water accumulated in the engine have a large error. In response to the above problems, relevant sensors can be used to obtain the initial amount of water accumulated in the engine, so that the determined amount of water accumulated in the engine can be more accurate. Specifically, it is described in detail below in conjunction with specific embodiments. In one possible implementation method, the initial amount of water accumulated in the engine is first obtained; then, based on the water production rate and the current running time of the engine, the newly added amount of water accumulated in the engine is determined; finally, based on the initial amount of water accumulated and the newly added amount of water accumulated, the amount of water accumulated in the engine is determined. It can be understood that based on the initial amount of water accumulated and the newly added amount of water accumulated, a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched dehydration operation, which to a certain extent avoids the phenomenon of engine oil emulsification.

[0110] Among them, regarding the above-mentioned "determining the newly accumulated water volume of the engine according to the water production rate and the current running time of the engine", the newly accumulated water volume of the engine can be determined by integral calculation. Specifically, in a possible implementation, the water production rate and the current running time of the engine are integrated to determine the newly accumulated water volume of the engine.

[0111] Exemplarily, the water production rate is F and the current running time of the engine is T1. Wherein, T1=t1-t2, as mentioned above, t1 is the time when the engine is started, and t2 is the current time.

[0112] Of course, in actual applications, technicians in this field can also determine the amount of newly accumulated water in the engine by other means, and this application does not impose any specific restrictions on this.

[0113] In the embodiment of the present application, the water production rate and the current running time of the engine are integrated to more quickly and accurately determine the newly accumulated water volume of the engine, thereby improving the water removal rate of the engine.

[0114] In the embodiment of the present application, the water production rate of the engine is first determined according to the current operating environment of the engine; then, the amount of water accumulated in the engine is determined according to the water production rate and the current operating time of the engine. It can be understood that based on the water production rate and the current operating time of the engine, a more accurate amount of water accumulated in the engine can be determined; based on the more accurate amount of water accumulated in the engine, the engine can perform a more matched dewatering operation, thereby avoiding the phenomenon of engine oil emulsification to a certain extent. Corresponding to the above embodiment, the present application also provides a dewatering control method for an engine.

[0115] For ease of understanding, Figure 2 Based on this, the present application also provides a flow chart of a water removal control method for an engine. Specifically, see Figure 3 , is a flow chart of a water removal control method for an engine provided in an embodiment of the present application. After step S202, it also includes:

[0116] Step S301: Based on the amount of water accumulated in the engine, determine whether the amount of water accumulated in the engine is greater than a water accumulation threshold.

[0117] In practical applications, in order to more accurately control the engine to perform the water removal operation, after determining the amount of water accumulated in the engine through the method embodiment described above, it is also necessary to determine whether the amount of water accumulated in the engine is greater than the water accumulation threshold. The water accumulation threshold is the boundary value for the engine to perform the water removal operation. It can be understood that in order to ensure the normal operation of the engine, the water accumulation threshold is less than or equal to the maximum value of the amount of water accumulated in the engine under the normal working state of the engine.

[0118] The water accumulation threshold is a value pre-set by a person skilled in the art. Of course, the user can also adjust the water accumulation threshold according to actual needs, and this application does not impose any specific restrictions on this.

[0119] Step S302: When the amount of water accumulated in the engine is greater than the water accumulation threshold, a water removal operation is performed on the engine to reduce the amount of water accumulated in the engine.

[0120] In the embodiment of the present application, when the amount of water accumulated in the engine is greater than the water accumulation threshold, the engine water removal operation is performed. Specifically, when the amount of water accumulated in the engine is greater than the water accumulation threshold, a relevant control instruction is output to control the engine to perform the water removal operation, thereby reducing the amount of water accumulated in the engine.

[0121] Exemplarily, the water accumulation threshold is 10ml. When the water accumulation in the engine is 12ml, since 12ml>10ml, that is, the water accumulation in the engine is greater than the water accumulation threshold, relevant control instructions are output at this time to control the engine to perform water removal operation; similarly, when the water accumulation in the engine is 13ml, since 13ml>10ml, that is, the water accumulation in the engine is greater than the water accumulation threshold, relevant control instructions are output at this time to control the engine to perform water removal operation; similarly, when the water accumulation in the engine is 9ml, since 9ml<10ml, that is, the water accumulation in the engine is less than the water accumulation threshold, relevant control instructions will not be output at this time to control the engine to perform water removal operation.

[0122] Specifically, in a possible implementation, when the amount of water accumulated in the engine is less than or equal to the water accumulation threshold, the amount of water accumulated in the engine is re-determined. It can be understood that when the amount of water accumulated in the engine is less than or equal to the water accumulation threshold, the engine water accumulation detection method corresponding to step S201-step S202 described above is re-executed to re-determine the amount of water accumulated in the engine.

[0123] Exemplarily, the water accumulation threshold is 10 ml. When the water accumulation in the engine is 9 ml, since 9 ml < 10 ml, that is, the water accumulation in the engine is less than the water accumulation threshold, the embodiment of the method for detecting the water accumulation in the engine corresponding to step S201-step S202 described above is re-executed to redetermine the water accumulation in the engine; similarly, when the water accumulation in the engine is 7 ml, since 7 ml < 10 ml, that is, the water accumulation in the engine is less than the water accumulation threshold, the embodiment of the method for detecting the water accumulation in the engine corresponding to step S201-step S202 described above is re-executed to redetermine the water accumulation in the engine.

[0124] In the embodiment of the present application, when the amount of water accumulated in the engine is less than or equal to the water accumulation threshold, the amount of water accumulated in the engine is re-determined, and the amount of water accumulated in the engine when the engine is working can be effectively monitored. It can be understood that monitoring the amount of water accumulated in the engine when the engine is working can ensure that when the amount of water accumulated in the engine is greater than the water accumulation threshold, the engine is promptly controlled to perform a water removal operation (i.e., perform an engine water removal operation) to reduce the amount of water accumulated in the engine, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0125] It should be noted that different amounts of water accumulated in different engines correspond to different water removal requirements. Therefore, in practical applications, in order to enable the engine to perform a more efficient water removal operation, the engine can be controlled to remove water at different water removal efficiencies according to the different amounts of water accumulated in the engine.

[0126] Specifically, in a possible implementation, when the amount of water accumulated in the engine is greater than the water accumulation threshold, firstly, the dewatering requirement level is determined according to the amount of water accumulated in the engine; then, according to the dewatering requirement level, the dewatering operation of the engine matching the dewatering requirement level is performed. Among them, the level value of the dewatering requirement level is positively correlated with the dewatering rate of the dewatering operation of the engine. It can be understood that the larger the level value of the dewatering requirement level (i.e., the more urgent the engine dewatering is), the faster the dewatering rate of the corresponding engine dewatering operation is.

[0127] It is understandable that in order to determine the dewatering requirement level, the corresponding relationship between the amount of water accumulated in the engine and the dewatering requirement level can be pre-stored in the relevant control module. Exemplarily, 0<water accumulation A<a and a<water accumulation B<b; the relationship between the amount of water accumulated in the engine and the dewatering requirement level is shown in Table 2. It is understandable that when the amount of water accumulated in the engine is water accumulation A, since 0<water accumulation A<a, the dewatering requirement level is determined to be dewatering requirement level I; similarly, when the amount of water accumulated in the engine is water accumulation B, since a<water accumulation B<b, the dewatering requirement level is determined to be dewatering requirement level II; and so on, the embodiments of the present application will not be repeated here.

[0128] Table 2:

[0129]

[0130]

[0131] It should be pointed out that the above table is only an exemplary illustration of the correspondence between the amount of water accumulated in the engine and the level of water removal requirement. In actual applications, those skilled in the art may set other correspondences between the amount of water accumulated in the engine and the level of water removal requirement, for example, a correspondence curve between the amount of water accumulated in the engine and the level of water removal requirement or a correspondence model between the amount of water accumulated in the engine and the level of water removal requirement.

[0132] As described above, after the dewatering requirement level is determined, it is also necessary to perform a dewatering operation of the engine that matches the dewatering requirement level according to the dewatering requirement level. Specifically, a corresponding relationship between the dewatering requirement level and the dewatering operation is pre-stored in the relevant control module. After the dewatering requirement level is determined, the dewatering requirement level is compared with the pre-stored corresponding relationship between the dewatering requirement level and the dewatering operation, and then the dewatering operation of the engine that matches the dewatering requirement level is determined.

[0133] Exemplarily, the dewatering operation corresponding to dewatering requirement level I is dewatering operation A; the dewatering operation corresponding to dewatering requirement level II is dewatering operation B; and the dewatering operation corresponding to dewatering requirement level III is dewatering operation C. When it is determined that the dewatering requirement level is dewatering requirement level I, the dewatering requirement level I is compared with the pre-stored correspondence between the dewatering requirement level and the dewatering operation, and then the dewatering operation of the engine matching the dewatering requirement level I is determined to be dewatering operation A; similarly, when it is determined that the dewatering requirement level is dewatering requirement level II, the dewatering requirement level II is compared with the pre-stored correspondence between the dewatering requirement level and the dewatering operation, and then the dewatering operation of the engine matching the dewatering requirement level II is determined to be dewatering operation B; similarly, and so on, which will not be elaborated in this application.

[0134] In an embodiment of the present application, a more accurate water removal requirement level (the urgency of engine water removal) can be determined based on the amount of water accumulated in the engine; based on the more accurate water removal requirement level, the engine can perform a more matched water removal operation, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0135] In an embodiment of the present application, first, after determining the amount of water accumulated in the engine through the method embodiment described above, a judgment is made as to whether the amount of water accumulated in the engine is greater than a water accumulation threshold; then, when the amount of water accumulated in the engine is greater than the water accumulation threshold, an engine water removal operation is performed to reduce the amount of water accumulated in the engine, thereby avoiding the phenomenon of engine oil emulsification to a certain extent.

[0136] In practical applications, in order to more accurately control the engine to stop the water removal operation, in one possible implementation method, the engine's water removal rate is first determined; then the engine's water removal amount is determined based on the water removal rate and the engine's current water removal time; finally, based on the engine's water accumulation amount and the engine's water removal amount, it is determined whether to stop the engine's water removal operation.

[0137] Specifically, in a possible implementation, the engine water removal rate is determined according to the current operating environment of the engine and / or the water removal requirement level. Of course, those skilled in the art may also determine the engine water removal rate in other ways according to actual needs, and this application does not make specific restrictions on this.

[0138] Regarding the above-mentioned “determining the amount of water removed from the engine according to the water removal rate and the current water removal time of the engine”, it should also be pointed out that the current water removal time of the engine is generally the time period from when the engine performs the water removal operation to the current water removal time. For example, if the time when the engine performs the water removal operation is time t3, then when it runs to the current water removal time t4, the current running time of the engine is t4-t3.

[0139] Specifically, in a possible implementation, an integration operation is performed on the water removal rate and the current water removal time of the engine to determine the water removal amount of the engine.

[0140] Exemplarily, the water removal rate is G, and the current water removal time of the engine is T2. Wherein, T2=t3-t4, as mentioned above, t3 is the time when the engine performs the water removal operation, and t4 is the current water removal time.

[0141] In the embodiment of the present application, based on the amount of water accumulated in the engine and the amount of water removed from the engine, it can be determined whether to stop the engine water removal operation. It can be understood that according to the amount of water accumulated in the engine and the amount of water removed from the engine, the engine water removal operation can be more accurately controlled to stop.

[0142] Of course, in practical applications, those skilled in the art may also determine the amount of water removed from the engine by other means, and this application does not impose any specific limitation on this.

[0143] Regarding the above-mentioned "determining whether to stop the engine's water removal operation based on the amount of water accumulated in the engine and the amount of water removed from the engine", in one possible implementation method, the amount of water accumulated in the engine and the amount of water removed are subtracted to determine the remaining amount of water accumulated in the engine; when the remaining amount of water accumulated in the engine is less than or equal to a water accumulation threshold value, the engine's water removal operation is stopped.

[0144] Exemplarily, the water accumulation threshold is 10 ml. When the water accumulation in the engine is 9 ml, since 9 ml < 10 ml, that is, the remaining water accumulation in the engine is less than or equal to the water accumulation threshold, the engine water removal operation is stopped at this time; similarly, when the water accumulation in the engine is 11 ml, since 11 ml > 10 ml, that is, the remaining water accumulation in the engine is greater than the water accumulation threshold, the engine water removal operation is continued at this time.

[0145] Of course, in practical applications, those skilled in the art may also determine the amount of remaining water in the engine by other means, and this application does not impose any specific restrictions on this.

[0146] In an embodiment of the present application, a subtraction operation is performed between the amount of water accumulated in the engine and the amount of water removed, thereby more quickly and accurately determining the remaining amount of water accumulated in the engine, thereby improving the water removal rate of the engine to a certain extent.

[0147] It should also be pointed out that, in a possible implementation, when it is detected that the engine oil needs to be replaced, the engine water removal operation will also be stopped.

[0148] In the embodiment of the present application, based on the amount of water accumulated in the engine and the amount of water removed from the engine, the engine can be more accurately controlled to stop the water removal operation, thereby improving the water removal rate of the engine to a certain extent.

[0149] It can be understood that the engine's water removal rate is obtained based on the engine's current working environment; based on the engine's water removal rate and the engine's current water removal time, a more accurate engine water removal amount can be determined; based on the engine's water accumulation amount and a more accurate engine water removal amount, the engine can be more accurately controlled to stop the water removal operation, thereby improving the engine's water removal rate to a certain extent.

[0150] In practical applications, the remaining amount of water in the engine can be determined based on the amount of water accumulated in the engine and the amount of water removed from the engine. Then, it is determined whether to stop the engine water removal operation based on the remaining amount of water accumulated in the engine. It can be understood that a more accurate remaining amount of water in the engine can be determined based on the amount of water accumulated in the engine and the amount of water removed from the engine. Based on the more accurate remaining amount of water accumulated in the engine, the engine can be more accurately controlled to stop the water removal operation, thereby improving the engine water removal rate to a certain extent.

If the amount of water accumulated in the engine is less than or equal to the water accumulation threshold, execute step S404; if the amount of water accumulated in the engine is greater than the water accumulation threshold, execute step S405.

[0156] Step S404: Re-determine the amount of water accumulated in the engine.
