[0003] In related technologies, the lubrication design of related lubrication components of electric drive assemblies is based on statistics of the amount of oil added to the main lubrication components and on experience to give an approximate value for the total amount of oil added. In the face of the current situation of increasing number of lubrication components, it is not possible to effectively control the amount of oil added, resulting in insufficient lubrication of related lubrication components of electric drive assemblies due to insufficient oil added, causing component wear and shortened service life.

[0010] In one embodiment of the present invention, after determining the adjusted initial oil filling amount as the minimum oil filling amount of the simulated lubrication system under the current operating conditions, the oil filling method of the simulated lubrication system further includes: determining the difference between the maximum speed and the preset maximum speed based on the maximum speed under the operating conditions, and determining the difference between the minimum speed and the preset minimum speed based on the minimum speed under the operating conditions; if the numerical difference between the maximum speed difference and the minimum speed difference is outside the optimized difference threshold range, the minimum oil filling amount under the operating conditions is adjusted until the numerical difference between the maximum speed difference and the minimum speed is within the optimized difference threshold range, and the adjusted oil filling amount is determined as the optimized minimum oil filling amount of the lubrication system under the current operating conditions.

[0011] In one embodiment of the present invention, after generating the multi-condition control chart of the electronic oil pump, the method for determining the lubrication amount of the simulated lubrication system further includes: determining the lubrication amount range of each operating condition based on the minimum lubrication amount and the maximum lubrication amount of multiple operating conditions; storing the lubrication amount range of each operating condition, the assembly lubrication amount range, and the multi-condition control chart of the electronic oil pump to a preset storage unit, so as to perform at least one of the following data processing on the lubrication amount range of each operating condition, the assembly lubrication amount range, and the multi-condition control chart of the electronic oil pump: data display, data transmission, and data filtering.

[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings and specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0028] The term "and / or" used in this application describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0029] First, it should be noted that in this application, "this time" and "last time" refer to the current adjustment of the refueling amount when the speed range of the electronic oil pump does not meet the preset usage range, so that the speed range of the electronic oil pump meets the preset usage range and reaches the critical condition. The refueling amount adjusted in this instance is the refueling amount that meets the condition in this instance. When the refueling amount exceeds the critical condition, the refueling amount adjusted in this instance is the refueling amount of the previous adjustment value of the adjusted refueling amount.

[0030] This application also provides the following benefits: Firstly, it determines the upper limit of the lubrication amount based on the oil content of the vent plug, preventing oil leakage in the lubrication system due to over-lubrication, which could lead to component failure or reduced component efficiency. Secondly, it conducts different tests under different operating conditions to obtain the upper and lower limits of the lubrication amount under each condition, and determines the upper and lower limits of the lubrication amount for the entire lubrication system assembly based on these limits to ensure the normal operation of each component under various operating conditions. Thirdly, it optimizes the minimum lubrication amount by determining an optimized minimum lubrication amount based on the difference between the tested speed range and the preset speed range, ensuring that the electronic oil pump speed reaches its optimal operating state under the optimized minimum lubrication amount. Finally, it generates a multi-condition control chart for the electronic oil pump by comparing the speed range of the electronic oil pump with the overall speed range under various operating conditions, for reference during lubrication system optimization design and other operations.

[0031] Figure 1 This is a schematic diagram illustrating an exemplary system architecture as shown in an exemplary embodiment of this application.

[0032] Reference Figure 1As shown, the system architecture may include a control device 101, a vehicle-side device 102, and a computer device 103. The control device 101 is used to perform a lubrication test on the simulated lubrication system with an initial lubrication amount, monitor the test operating speed of the electronic oil pump of the lubrication system at the vehicle-side device 102, and provide the data to the computer device 102 for processing. The vehicle-side device 102 can be at least one of a physical vehicle, a digital twin vehicle, a simulated model vehicle, or a vehicle abstract architecture. The computer device 103 can be at least one of a microcomputer, an embedded computer, or a network computer. Technical personnel can use the computer device 103 to obtain the current operating condition preset speed range of the simulated lubrication system, determine the speed range difference based on the current operating condition preset speed range and the operating condition test operating speed range, adjust the initial lubrication amount according to the speed range difference until the operating condition test operating speed range meets the range requirement of the current operating condition preset speed range, and determine the adjusted initial lubrication amount as the minimum lubrication amount for the simulated lubrication system under the current operating condition.

[0033] Indicatively, after the computer device 103 receives information that the control device 101 has performed a lubrication test on the simulated lubrication system with an initial lubrication amount, monitors the test operating speed of the electronic oil pump of the lubrication system at the vehicle end 102, and obtains the current operating condition preset speed range of the simulated lubrication system, it determines the speed range difference based on the current operating condition preset speed range and the operating condition test operating speed range, and adjusts the initial lubrication amount until the operating condition test operating speed range meets the range requirements of the current operating condition preset speed range. The adjusted initial lubrication amount is then determined as the minimum lubrication amount of the simulated lubrication system under the current operating condition. The lower limit of the lubrication amount of the simulated lubrication system is determined based on the test speed range of the electronic oil pump and the preset speed range, so that the lubrication amount meets the minimum operating requirements of the simulated lubrication system, effectively improving the control of the lubrication amount and reducing component wear caused by insufficient lubrication amount in the lubrication system.

[0034] Figure 2 This is a flowchart illustrating an exemplary embodiment of the present application of a method for determining the amount of oil added to a simulated lubrication system. This method can be executed using a computational processing device, which may be... Figure 1 The computer device 103 shown is illustrated. (Refer to...) Figure 2 As shown, the flowchart of the method for determining the amount of oil added in the simulated lubrication system includes at least steps S210 to S20, which are described in detail below:

[0035] In step S210, the simulated lubrication system is lubricated with an initial amount of oil, and the test operating speed of the electronic oil pump of the simulated lubrication system is monitored to obtain the operating speed range under working conditions.

[0036] In one embodiment of this application, the initial refueling amount can be determined according to the requirements of the test environment, or it can be estimated in a preliminary simulation experiment. The specific method for determining the initial refueling amount can be adjusted according to the data requirements of the scheme in actual application. Here, the method for determining the initial refueling amount is not specifically limited.

[0037] In one embodiment of this application, the simulated lubrication system consists of a reducer, oil cooling components, a motor, etc., and is specifically used to evaluate the lubrication of components such as reducer gears, reducer bearings, reducer exhaust plugs, reducer input shaft splines, electronic oil pump inlet, motor oil injection rings, motor shafts, and motor bearings, so as to meet the minimum lubrication requirements of the simulated lubrication system.

[0038] In step S220, the current operating condition preset speed range of the simulated lubrication system is obtained, and the speed range difference is determined based on the current operating condition preset speed range and the operating condition test speed range.

[0039] In one embodiment of this application, the current operating condition is first determined based on the simulated lubrication system, and then the preset speed range of the current operating condition is obtained based on the current operating condition. The preset speed range of the current operating condition is the speed range of the electronic oil pump determined based on the test environment, the maximum operating capacity of the electronic oil pump, and the actual operating requirements. It can be set by those skilled in the art as needed.

[0040] In one embodiment of this application, the operating condition test speed range is less than or equal to the current operating condition preset speed range.

[0041] In one embodiment of this application, the speed range difference is determined based on the current operating condition preset speed range and the operating condition test running speed range, including but not limited to the maximum operating speed being greater than the preset maximum speed and the minimum operating speed being less than the preset minimum speed. Alternatively, taking the operating condition test running speed range as [minimum operating speed a, maximum operating speed b] and the current operating condition preset speed range as [preset minimum speed c, preset maximum speed d] as an example, the speed range difference is determined by identifying the minimum difference (ac) and the maximum difference (bd), and then using the numerical signs and magnitudes of the minimum and maximum differences as the speed range difference. Subsequently, when adjusting the initial refueling amount, the adjustment value can be a uniform adjustment at a preset amount, or the adjustment amount can be determined based on the magnitude of the difference, thereby adjusting the initial refueling amount. For example, different adjustment amounts can be preset for different difference magnitudes; when the difference is small, the adjustment amount is small, and when the difference is large, the adjustment amount is large.

[0042] In another embodiment of this application, the difference from the above embodiment is that determining the speed range difference based on the operating condition test speed range includes setting a speed range deviation threshold range in advance. If the difference between the operating condition test speed range and the preset speed range is outside the speed range deviation threshold range, the amount of fuel is reduced until the difference between the operating condition test speed range and the preset speed range is within the speed range deviation threshold range. Then, the adjusted amount of fuel is determined as the minimum amount of fuel.

[0043] In step S230, the initial oil filling amount is adjusted according to the difference in speed range until the speed range of the test operation meets the range requirement of the preset speed range of the current operating condition. The adjusted initial oil filling amount is then determined as the minimum oil filling amount of the simulated lubrication system under the current operating condition.

[0044] In one embodiment of this application, the operating condition test speed range is less than or equal to the current operating condition preset speed range. Adjusting the initial fuel filler quantity based on the speed range difference includes at least one of the following: if the highest operating speed is greater than the preset highest speed, the initial fuel filler quantity is reduced until the highest operating speed is less than or equal to the preset highest speed, and the lowest operating speed is greater than or equal to the preset lowest speed; in this case, the adjusted fuel filler quantity is determined as the minimum fuel filler quantity for the current operating condition. If the lowest operating speed is less than the preset lowest speed, the initial fuel filler quantity is increased until the lowest operating speed is greater than or equal to the preset lowest speed, and the highest operating speed is less than or equal to the preset highest speed; in this case, the adjusted fuel filler quantity is determined as the minimum fuel filler quantity for the current operating condition. The highest and lowest operating speeds can be determined based on the operating condition test speed range, and the preset highest and lowest operating speeds can be determined based on the current operating condition preset speed range.

[0045] In one embodiment of this application, after determining the adjusted initial oil filling amount as the minimum oil filling amount of the simulated lubrication system under the current operating conditions, the oil filling method of the simulated lubrication system further includes determining the difference between the maximum speed under the operating conditions and the preset maximum speed, and determining the difference between the minimum speed under the operating conditions and the preset minimum speed; if the difference between the maximum speed difference and the minimum speed difference is outside the optimized difference threshold range, the minimum oil filling amount under the operating conditions is adjusted until the difference between the maximum speed difference and the minimum speed is within the optimized difference threshold range, and then the adjusted oil filling amount is determined as the optimized minimum oil filling amount of the lubrication system under the current operating conditions. For example, if the operating speed range for the test is [minimum operating speed a, maximum operating speed b], and the current preset operating speed range is [preset minimum speed c, preset maximum speed d], where a is greater than or equal to c and b is less than or equal to d, and the difference between the values ​​of ac and db is outside the optimized difference threshold range, then the initial lubrication amount is adjusted until the difference between the values ​​of ac and db is within the optimized difference threshold range, thus obtaining the optimized minimum lubrication amount for the lubrication system under the current operating conditions.

[0046] In one embodiment of this application, the adjustment value for increasing or decreasing the initial refueling amount can be determined by directly setting the increase or decrease value according to the accuracy requirements, such as increasing or decreasing the refueling amount by 0.1L each time. Alternatively, the refueling amount can be adjusted by increasing or decreasing the value arithmetically, such as 0.1L, 0.08L, 0.06L, 0.04L, etc., or by decreasing the value proportionally, such as 0.1L, 0.05L, 0.025L, 0.0125L, etc. Thus, the adjustment amount of the refueling amount can be specifically set according to the accuracy requirements of the numerical value in actual applications, and no specific limitation is made on the adjustment amount of the refueling amount here.

[0047] In one embodiment of this application, after performing a lubrication test on the simulated lubrication system with an initial lubrication amount, the method for determining the lubrication amount of the simulated lubrication system further includes: monitoring the oil content of the vent plug of the simulated lubrication system; if the oil content of the vent plug is oily, then reducing the initial lubrication amount until the oil content of the vent plug is no longer oily, and determining the adjusted lubrication amount as the maximum lubrication amount under the current operating conditions; if the oil content of the vent plug is no longer oily, then increasing the current lubrication amount until the oil content of the vent plug is oily, and determining the previously adjusted lubrication amount as the maximum lubrication amount under the current operating conditions.

[0048] In one embodiment of this application, if the oil-containing state of the vent plug is not oil-free, the current oil filling amount is increased until the oil-containing state of the vent plug is oil-containing. After determining the previously adjusted oil filling amount as the maximum oil filling amount of the lubrication system under the current operating conditions, the method for determining the oil filling amount of the simulated lubrication system further includes: adjusting the current operating conditions of the simulated lubrication system to obtain the minimum oil filling amount and the maximum oil filling amount of multiple operating conditions of the simulated lubrication system; determining the minimum oil filling amount of the assembly with the largest value among the minimum oil filling amounts of multiple operating conditions; determining the maximum oil filling amount of the assembly with the smallest value among the maximum oil filling amounts of multiple operating conditions; and determining the assembly oil filling amount range based on the minimum oil filling amount and the maximum oil filling amount of the assembly.

[0049] In one embodiment of this application, after determining the assembly lubrication quantity range based on the assembly's minimum and maximum lubrication quantities, the method for determining the lubrication quantity of the simulated lubrication system further includes performing a lubrication test on the simulated lubrication system using the assembly's minimum lubrication quantity, monitoring the test operating speed of the electronic oil pump in the simulated lubrication system, and obtaining the assembly's test operating speed range; performing a lubrication test on the simulated lubrication system using the minimum lubrication quantities for multiple operating conditions, monitoring the test operating speed of the electronic oil pump in the simulated lubrication system, and obtaining the operating condition test operating speed range for multiple operating conditions; and generating a multi-condition control chart for the electronic oil pump based on the assembly test operating speed range, the operating condition test operating speed ranges for multiple operating conditions, the assembly's minimum lubrication quantity, and the minimum lubrication quantities for multiple operating conditions.

[0050] In one embodiment of this application, the multi-condition control diagram of the electronic oil pump mainly reflects the distribution of motor efficiency and motor speed under different operating conditions and different oil filling amounts, and is also known as the multi-condition map of the electronic oil pump.

[0051] In one embodiment of this application, after generating the multi-condition control chart of the electronic oil pump, the method for determining the lubrication amount of the simulated lubrication system further includes determining the lubrication amount range of each operating condition based on the minimum lubrication amount and the maximum lubrication amount of multiple operating conditions; storing the lubrication amount range of each operating condition, the assembly lubrication amount range, and the multi-condition control chart of the electronic oil pump to a preset storage unit, so as to perform at least one of the following data processing: data display, data transmission, and data filtering on the lubrication amount range of each operating condition, the assembly lubrication amount range, and the multi-condition control chart of the electronic oil pump.

[0052] The beneficial effects provided by this application include: determining the lower limit of the lubrication quantity of the simulated lubrication system based on the test speed range and preset speed range of the electronic oil pump, so as to ensure that the lubrication quantity meets the minimum operating requirements of the simulated lubrication system, effectively improving the control of the lubrication quantity, and reducing component wear caused by insufficient lubrication quantity; determining the upper limit of the lubrication quantity based on the oil content of the vent plug, avoiding oil leakage due to over-lubrication, which could cause component failure or reduce component efficiency; secondly, conducting different tests under different operating conditions to obtain the upper and lower limits of the lubrication quantity under each operating condition, and determining the upper and lower limits of the lubrication quantity of the entire lubrication system based on the upper and lower limits of the lubrication quantity under each operating condition, so as to meet the normal operation of each component under each operating condition; furthermore, determining the optimized minimum lubrication quantity based on the difference between the test speed range and the preset speed range of the operating condition, so that the electronic oil pump speed reaches the optimal operating state under the optimized minimum lubrication quantity; and generating a multi-condition control chart of the electronic oil pump based on the speed range of the electronic oil pump and the speed range of the entire system under each operating condition, for reference during operations such as lubrication system optimization design.

[0053] Please see Figure 3 , Figure 3 This is an exemplary embodiment of the present application illustrating the execution flowchart of a specific simulation lubrication system lubrication quantity determination method. This method can be applied to... Figure 2 The implementation environment is illustrated, and is specifically executed by control device 101 and / or vehicle terminal 102 and / or computer device 103 within that implementation environment. It should be understood that the method can also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments; this embodiment does not limit the implementation environment to which the method is applicable.

[0054] like Figure 3 As shown, the designed lubrication system is input, and the structure is designed according to the lubrication system design. Then, simulation analysis is performed. After the analysis, the range of oil filling volume and the electronic oil pump speed map are output.

[0055] In one specific embodiment of this application, the simulation analysis includes obtaining and outputting the lower limit of the oil filling amount. This process includes first conducting a lubrication experiment to determine whether the oil pump speed is within the operating oil pump speed range. If the oil pump speed does not meet the operating oil pump speed range, the oil filling amount is reduced and the above steps are repeated until the oil pump speed meets the operating oil pump speed range and the lower limit of the oil filling amount is output. In this specific embodiment, the threshold for the operating oil pump speed range is 0 rpm. When the speed range is greater than or equal to 0 rpm, the oil filling amount is reduced. In this specific embodiment, the amount of oil filling reduced is 0.1L. When the speed range is less than 0 rpm, the oil volume of the previous cycle is output as the lower limit of the oil filling amount.

[0056] In one specific embodiment of this application, after simulation analysis, an air exchange test is also performed to determine whether there is oil in the exhaust plug. If there is no oil, the amount of oil added is increased. In this specific embodiment, the amount of oil added is increased by 0.1L until there is oil in the exhaust plug. Then, the upper limit of the amount of oil added is output. The upper limit of the amount of oil added is the amount of oil in the previous cycle.

The filter in the electronic oil pump processes the lubricating oil and transmits the processed lubricating oil to the gear transmission part for lubrication. On the other hand, the processed lubricating oil is transmitted to the oil cooler and then transmitted to the motor stator and motor rotor for lubrication. Finally, the lubricated lubricating oil is circulated back to the reducer oil chamber.
