Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engine cooling system control, and particularly relates to a deformation detection method and device of an engine thermostat, an electronic device and a medium. BACKGROUND

[0002] In response to the trend of energy saving and emission reduction of automobiles, heat management modules are gradually used in automobile engines to replace traditional thermostats to control the flow rate of coolant in the circulating branch of the engine cooling system, so as to achieve temperature control and better fuel consumption and emission effects.

[0003] Currently, there are two commonly used methods for diagnosing the deformation of the thermostat valve body in the heat management module. The first method is to specify the replacement period of the thermostat valve in the heat management module in the vehicle maintenance manual. However, this method cannot monitor the valve body in real time for abnormalities. Once the valve body boundary changes, the water temperature control accuracy will be affected, and there is a safety hazard. The second method is that when the vehicle prompts a coolant abnormality, the instrument panel displays an abnormal coolant temperature, prompting the driver to go to a repair shop for replacement. However, the coolant abnormality cannot determine whether the thermostat valve in the heat management module is damaged, and it is also possible that the water pump or fan system has a problem. Therefore, this method cannot accurately identify the aging abnormality of the valve body, and there is a safety hazard.

[0004] Therefore, it is very important to accurately determine the aging abnormality of the thermostat valve body. SUMMARY

[0005] The present application provides a deformation detection method and device of an engine thermostat, an electronic device and a medium, to accurately determine the aging abnormality of the thermostat valve body and avoid safety hazards caused by valve body aging.

[0006] According to an aspect of the present application, a deformation detection method of an engine thermostat is provided, which comprises:

[0007] detecting whether the thermostat valve satisfies a preset enabling condition matched with the operating state of the thermostat valve, the preset enabling condition being used to determine whether to perform deformation detection on the thermostat valve;

[0008] if the preset enabling condition is satisfied, a constant force is applied to the thermostat valve for a preset time length;

[0009] determining a current valve body position corresponding to the end of valve body movement of the thermostat valve within the preset time length;

[0010] determining the deformation degree of the thermostat valve based on the current valve body position and a current boundary position of the thermostat valve, the current boundary position being a boundary limit value that can be reached by the valve body movement of the thermostat valve, and the boundary position adopted by the valve body of the thermostat valve being different in different operating states.

[0011] According to another aspect of the present invention, a deformation detection device for an engine thermostat valve is provided, the device comprising:

[0012] The detection module is used to detect whether the thermostat valve meets the preset enable conditions that match the operating state of the thermostat valve. The preset enable conditions are used to determine whether to perform deformation detection on the thermostat valve.

[0013] The judgment module is used to apply a constant force to the thermostat valve for a preset duration if the condition is met.

[0014] The position determination module is used to determine the current valve body position corresponding to the end of the valve body movement within a preset time period;

[0015] The deformation degree determination module is used to determine the deformation degree of the thermostatic valve based on the current valve body position and the current boundary position of the thermostatic valve. The current boundary position is the boundary limit that the valve body of the thermostatic valve can reach by movement. The boundary position adopted by the valve body of the thermostatic valve is different in different operating states.

[0016] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0017] At least one processor; and

[0018] A memory communicatively connected to the at least one processor; wherein,

[0019] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the deformation detection method for the engine thermostat valve according to any embodiment of the present invention.

[0020] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the deformation detection method of the engine thermostat valve according to any embodiment of the present invention.

[0021] The technical solution of this invention detects whether the thermostat valve meets a preset enabling condition that matches its operating state. If it does, a constant force is applied to the thermostat valve for a preset duration. The current valve body position is determined at the end of the valve body movement within the preset duration. The degree of deformation of the thermostat valve is determined based on the current valve body position and the current boundary position of the thermostat valve. This technical solution, after determining that the thermostat valve meets the preset enabling condition that matches its operating state, accurately determines the degree of deformation of the thermostat valve by comparing the current valve body position with the current boundary position. This achieves accurate determination of aging abnormalities in the thermostat valve body and avoids safety hazards caused by valve body aging.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," and "current," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Example 1

[0034] Figure 1 This is a flowchart illustrating a deformation detection method for an engine thermostat valve according to an embodiment of the present invention. This embodiment is applicable to situations where the deformation degree of the thermostat valve is detected under different operating conditions. The method can be executed by an engine thermostat valve deformation detection device, which can be implemented in hardware and / or software. This engine thermostat valve deformation detection device can be configured in an electronic device that includes an engine thermostat valve deformation detection method. Figure 1 As shown, the method includes:

[0035] S110. Detect whether the thermostat valve meets the preset enable conditions that match the operating state of the thermostat valve. The preset enable conditions are used to determine whether to perform deformation detection on the thermostat valve.

[0036] The operating state of the thermostat valve can include a first operating state and a second operating state. The first operating state is the process in which the valve body of the thermostat valve moves to the maximum opening degree, and the second operating state is the process in which the valve body of the thermostat valve moves to the minimum opening degree.

[0037] Specifically, the preset enabling conditions are different when the thermostat is in different operating states. When it is in the first operating state, it matches the first preset enabling condition, and when it is in the second operating state, it matches the second preset enabling condition. That is, when the thermostat is in the first operating state, it is determined whether the current operating condition of the thermostat meets the first preset enabling condition in order to accurately detect the degree of deformation. When the thermostat is in the second operating state, it is determined whether the current operating condition of the thermostat meets the second preset enabling condition in order to accurately detect the degree of deformation.

[0038] S120. If satisfied, a constant force will be applied to the thermostat valve for a preset duration.

[0039] Specifically, when the thermostat valve meets the preset enable conditions that match its operating state, it means that the degree of deformation of the thermostat valve can be detected. First, the valve body motor needs to provide a constant force to the valve body (such as a constant PWM drive signal) and continue to apply it for a preset duration to obtain information for subsequent detection. When the thermostat valve is in different operating states, the duration of application can be determined according to the current operating state, and can be the same or different.

[0040] S130. Determine the current valve body position corresponding to the end of the valve body movement within the preset time period.

[0041] Specifically, when the thermostat moves within a preset time period, the amount of movement change of the thermostat is acquired at preset time intervals. If the amount of movement change is less than the preset movement change threshold and continues for the preset time, the current opening of the thermostat is taken as the current position of the valve body. The preset movement time is to avoid the situation where the amount of movement change is less than the preset movement change threshold due to the sudden stop of the valve body. This may be caused by the movement being uneven, rather than by the deformation of the valve body. Therefore, maintaining the preset movement time can ensure that the inability to move forward is indeed due to the deformation of the thermostat, thus avoiding incorrect judgment.

[0042] S140. Determine the degree of deformation of the thermostatic valve based on the current valve body position and the current boundary position of the thermostatic valve.

[0043] The current boundary position is the boundary limit that the valve body of the thermostat can reach by moving. The boundary position of the valve body of the thermostat is different in different operating states.

[0044] Specifically, by obtaining the current valve body position and the current boundary position of the thermostat valve, the degree of deformation of the thermostat valve can be determined by comparing the difference between the two with a preset difference. When the thermostat valve is in the first operating state, the first boundary position is used as the current boundary position; when the thermostat valve is in the second operating state, the first boundary position is used as the current boundary position. The first boundary position represents the maximum opening that the thermostat valve could achieve in the previous first operating state, and the second boundary position represents the minimum opening that the thermostat valve could achieve in the previous second operating state.

[0045] The technical solution of this invention detects whether the thermostat valve meets a preset enabling condition that matches its operating state. If it does, a constant force is applied to the thermostat valve for a preset duration. The current valve body position is determined at the end of the valve body movement within the preset duration. The degree of deformation of the thermostat valve is determined based on the current valve body position and the current boundary position of the thermostat valve. This technical solution, after determining that the thermostat valve meets the preset enabling condition that matches its operating state, accurately determines the degree of deformation of the thermostat valve by comparing the current valve body position with the current boundary position. This achieves accurate determination of aging abnormalities in the thermostat valve body and avoids safety hazards caused by valve body aging.

[0046] Example 2

[0047] Figure 2 This is a flowchart illustrating a deformation detection method for an engine thermostat valve according to an embodiment of the present invention. This embodiment provides a detailed description of the degree of deformation of the thermostat valve when it is in its first operating state. Figure 2 As shown, the method includes:

[0048] S210. When the thermostat is in the first operating state, after determining that the thermostat meets the first preset enabling condition, a constant force is applied to the thermostat for a preset duration.

[0049] For details, see Figure 3 When the thermostat is in its first operating state, the engine is started, and the engine start-up end time t and the desired opening degree θ of the thermostat are obtained. e1 and actual opening θ a1 The start-up end time is the time from engine start-up to stable rotation, and the first operating state is the process of the thermostat valve body moving to its maximum opening. If the start-up end time is greater than a preset time, and the desired opening is greater than the first preset desired opening θ1, and the actual opening is greater than the first preset actual opening θ2, and the actual opening is within the first preset opening range, then the thermostat valve is determined to meet the first preset enabling condition. The first preset opening range is determined based on the desired opening and the preset error opening. For example, the first preset opening range can be θ... e1 -δ1<θ a1 <θ e1 +δ1.

[0050] S220. Determine the current valve body position corresponding to the end of the valve body movement within the preset time period.

[0051] Specifically, within a preset time period, the movement change of the thermostat valve is acquired at preset time intervals; if the movement change is less than a preset movement change threshold and continues for a preset movement time, the current opening degree of the thermostat valve is taken as the current valve body position.

[0052] S230. Determine the degree of deformation of the thermostatic valve based on the current valve body position and the first boundary position of the thermostatic valve.

[0053] Specifically, the first boundary position of the thermostat valve is obtained, and the difference between the current valve body position and the first boundary position is used as the first parameter Δ1. If the first parameter Δ1 is within the first preset difference range, that is, the first parameter satisfies Th1<Δ1<Th2, then the current valve body position is used as the updated first boundary position. If the first boundary position is greater than the first preset boundary threshold, it indicates that the deformation of the current thermostat valve is small, and it does not need to be replaced and can continue to be used. The updated first boundary position is used as the first boundary position for the next detection.

[0054] If the first parameter satisfies Th1<Δ1<Th2, but the first boundary position is less than the first preset boundary threshold, then it is determined that the thermostatic valve is deformed abnormally and the valve body is severely aged and needs to be replaced.

[0055] If Δ1 > Th2, it means there is an error in the detection data, and this detection should be discarded.

[0056] If Δ1 < Th1, it means that the deformation of the thermostat valve is very small and can be ignored. Continue to use the first boundary position for subsequent testing.

[0057] The technical solution of this invention, when the thermostat valve is in the first operating state, after determining that the thermostat valve meets the first preset enabling condition, applies a constant force to the thermostat valve for a preset duration, determines the current valve body position corresponding to the end of the valve body movement within the preset duration, and determines the degree of deformation of the thermostat valve based on the current valve body position and the first boundary position of the thermostat valve, thereby accurately determining the aging abnormality of the thermostat valve body and avoiding safety hazards caused by valve body aging.

[0058] Example 3

[0059] Figure 4 This is a flowchart illustrating a deformation detection method for an engine thermostat valve according to an embodiment of the present invention. This embodiment provides a detailed description of the degree of deformation of the thermostat valve when it is in a second operating state. Figure 4 As shown, the method includes:

[0060] S310. When the thermostat valve is in the second operating state, after determining that the thermostat valve meets the first preset enabling condition, a constant force is applied to the thermostat valve for a preset duration.

[0061] For details, see Figure 5 When the thermostat is in its second operating state, the engine is started, and the engine start-up end time t and the desired opening degree θ of the thermostat are obtained. e2 and actual opening θa2 The start-up end time is the time from engine start-up to stable operation, and the second operating state is the process of the thermostat valve body moving towards its maximum minimum opening. If the start-up end time is greater than the preset time, and the desired opening is less than the second preset desired opening θ3, and the actual opening is less than the second preset actual opening θ4, and the actual opening is within the second preset opening range, then the thermostat valve is determined to meet the second preset enabling condition. The second preset opening range is determined based on the desired opening and the preset error opening, and the second preset opening range can be θ. e2 -δ2<θ a2 <θ e2 +δ2.

[0062] S320. Determine the current valve body position corresponding to the end of the valve body movement within the preset time period.

[0063] Specifically, within a preset time period, the movement change of the thermostat valve is acquired at preset time intervals; if the movement change is less than a preset movement change threshold and continues for a preset movement time, the current opening degree of the thermostat valve is taken as the current valve body position.

[0064] S330. Determine the degree of deformation of the thermostatic valve based on the current valve body position and the second boundary position of the thermostatic valve.

[0065] Specifically, the second boundary position of the thermostat valve is obtained, and the difference between the current valve body position and the second boundary position is used as the second parameter Δ2. If the second parameter is within the second preset difference range, that is, the second parameter satisfies Th3<Δ2<Th4, then the current valve body position is used as the updated second boundary position. If the updated second boundary position is greater than the second preset boundary threshold, it indicates that the deformation of the current thermostat valve is small, and it does not need to be replaced and can continue to be used. The updated second boundary position is used as the first boundary position for the next detection.

[0066] If the second parameter satisfies Th3<Δ2<Th4, and the updated second boundary position is less than the second preset boundary threshold, then it is determined that the thermostatic valve is deformed abnormally and the valve body is severely aged and needs to be replaced.

[0067] If Δ2 > Th4, it indicates that there is an error in the detection data, and this detection should be discarded.

[0068] If Δ2 < Th3, it means that the deformation of the thermostat valve is very small and can be ignored. Continue to use the first boundary position for subsequent testing.

[0069] The technical solution of this invention, when the thermostat valve is in the second operating state, after determining that the thermostat valve meets the second preset enabling condition, applies a constant force to the thermostat valve for a preset duration, determines the current valve body position corresponding to the end of the valve body movement within the preset duration, and determines the degree of deformation of the thermostat valve based on the current valve body position and the second boundary position of the thermostat valve, thereby accurately determining the aging abnormality of the thermostat valve body and avoiding safety hazards caused by valve body aging.

[0075] The deformation degree determination module 440 is used to determine the deformation degree of the thermostatic valve based on the current valve body position and the current boundary position of the thermostatic valve.
