[0051] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0052] The following describes the solutions of the embodiments of the present invention in conjunction with the accompanying drawings.

[0053] The calculation premise of the oil addition amount of the present invention is to confirm the oil addition amount of the lubrication system based on the lubrication system that has been running; through the scheme of the present application, the oil addition amount that needs to be added to the lubrication system when setting the oil replenishment interval is confirmed.

[0054] See also Figure 1 A method for determining the amount of oil added to a lubrication system, the lubrication system comprising an oil pan and oil, the oil pan being located at the lower part of the lubrication system and used to contain the oil, the method comprising:

[0055] Step 110, obtaining the minimum oil volume in the oil pan, the minimum oil volume being obtained by the amount of suspended wall oil and the oil consumption of the engine within a set oil change cycle.

[0056] When determining how much oil needs to be added to the lubrication system, it is necessary to first determine the range in the oil pan that can store oil, so it is necessary to obtain the minimum amount of oil that can be stored in the oil pan (i.e., the minimum oil storage amount). When obtaining the minimum oil storage amount in the oil pan, since the lubrication system is in operation or has been in operation, there is a suspended amount of oil hanging on the wall in the lubrication system; in addition, since the addition of oil to the lubrication system or the inspection of the oil level is performed after a set time (the set time is the set oil change cycle), it is also necessary to consider the oil consumption within the set oil change cycle. In summary, when obtaining the minimum oil storage amount in the oil pan, the parameters that need to be considered are the suspended amount of oil hanging on the wall and the oil consumption of the engine within the set oil change cycle.

[0057] In the embodiment, the amount of suspended wall oil refers to: in the lubrication system, due to the operation of the lubrication system, there is oil hanging on the wall or suspended in the air in places such as the wall, oil channel and air (that is, the amount of oil that has not fallen into the oil pan). Therefore, when considering the minimum oil storage amount in the oil pan, the amount of suspended and wall oil needs to be taken into consideration.

[0058] Step 120, obtaining the maximum oil storage amount in the oil pan, the maximum oil storage amount is obtained by the upper limit of the engine oil.

[0059] When determining how much oil needs to be added to the lubrication system, it is necessary to determine the range in the oil pan that can store oil. Therefore, it is necessary to obtain the maximum amount of oil that can be stored in the oil pan (i.e., the maximum oil storage amount). When limiting the maximum oil storage amount, you can refer to the limit on the maximum vertical height of the oil.

[0060] Step 130 , obtaining the oil storage range of the oil pan according to the minimum oil storage amount and the maximum oil storage amount.

[0061] After obtaining the minimum oil storage amount and the maximum oil storage amount, the minimum oil storage amount and the maximum oil storage amount are combined to form an oil storage range, and the oil storage range is the range of the capacity of the engine oil that can be accommodated in the oil pan.

[0062] Step 140, obtaining the oil volume range that needs to be added to the oil pan according to the oil storage range.

[0063] After obtaining the oil storage interval, the oil volume in the current oil pan is determined to obtain the oil adding interval that needs to be added to the oil pan; therefore, when adding oil to the oil pan, it is sufficient to ensure that the amount of oil added is within the obtained oil adding interval. In some embodiments, when determining the amount of oil added, the middle value or the upper middle value of the oil adding interval is taken to determine the amount of oil that needs to be added.

[0064] By adopting the scheme of the present application, the oil amount in the oil pan of the lubrication system that has been running is obtained, and the minimum and maximum oil amounts in the oil pan are obtained. Then, the oil storage range in the oil pan can be obtained according to the minimum and maximum oil amounts in the oil pan, so as to know the oil amount range that needs to be added to the oil pan according to the oil storage range, so as to reasonably plan the oil addition amount when adding oil to the oil pan, to avoid the oil addition amount exceeding the oil amount range, that is, to avoid the oil amount in the oil pan after addition exceeding the oil storage range; the present invention realizes the on-demand provision of oil flow in the lubrication system, reduces the shaft power consumption of the oil pump, and thus is beneficial to reducing the fuel consumption of the engine.

[0065] Specifically, there is no fixed order for step 110 and step 120 , and the sequence numbers of step 110 and step 120 do not constitute a limitation on the execution order of the two steps.

[0066] In some embodiments of the present application, in step 110, obtaining the minimum oil volume in the oil pan includes:

[0067] Step 111, obtaining the initial oil addition amount and the first suspended wall oil amount in the oil pan, and obtaining the first minimum oil storage amount according to the difference between the initial oil addition amount and the first suspended wall oil amount; wherein the first suspended wall oil amount corresponds to the lubrication system being in a working state or just stopped state.

[0068] Since the purpose is to obtain the minimum oil storage volume in the oil pan, it is necessary to confirm the minimum amount of engine oil in the oil pan. Since the oil pan is located below the lubrication system and is used to receive the engine oil, the engine oil can be hung on the wall or suspended in the air at the corresponding position. Therefore, when the first suspended wall oil volume is the largest, the corresponding engine oil volume in the oil pan is the smallest; after the lubrication system stops running, part of the suspended and wall oil will flow into the oil pan. Therefore, when the lubrication system is in working state or has just stopped, the corresponding first suspended wall oil volume is the largest, and the oil volume in the oil pan is the smallest at this time; best, considering that part of the engine oil drips into the oil pan during shutdown, the first suspended wall oil volume can be taken to get the maximum value when the lubrication system is in working state.

[0069] Step 112, obtaining a second minimum oil level in the oil pan, the second minimum oil level corresponding to the oil pan being in a tilted state.

[0070] When obtaining the minimum oil volume in the oil pan, the state of the oil pan must also be considered, that is, whether the oil pan is in a tilted state. When the oil pan is tilted, it will affect the liquid level in the oil pan, thereby affecting the minimum oil volume in the oil pan. When the oil pan is in a tilted state, the corresponding state of the car includes: the car is climbing, accelerating, decelerating downhill, etc. During these operations that affect the liquid level of the car, the oil in the corresponding oil pan will tilt, but the oil will always remain in the oil pan and will not flow out of the oil pan.

[0071] Specifically, there is no fixed order for step 111 and step 112, and the sequence numbers of step 111 and step 112 do not constitute a limitation on the execution order of the two steps.

[0072] Step 113, obtaining the minimum oil storage amount through the first minimum oil storage amount and the second minimum oil storage amount.

[0073] In some embodiments of the present application, a first minimum oil level is obtained by a first suspended wall oil level in the oil pan, and a second minimum oil level is obtained by an inclined state of the oil pan. Since the working states corresponding to the first minimum oil level and the second minimum oil level need to be satisfied simultaneously in the oil pan, when the minimum oil level is obtained by the first minimum oil level and the second minimum oil level, it is necessary to obtain the minimum oil level based on the larger value of the first minimum oil level and the second minimum oil level to avoid the problem of too low oil level in the oil pan.

[0074] In some embodiments of the present application, in step 112, obtaining the second minimum oil level in the oil pan includes:

[0075] Step 112 - 1 , obtaining the lowest oil storage height of the oil in the oil pan when the oil pan is at the maximum lateral inclination or the maximum longitudinal inclination.

[0076] When the oil pan is tilted, the minimum oil storage height corresponding to the maximum tilt of the oil pan in two directions (i.e., the minimum oil storage height when the oil pan is at the maximum lateral tilt or the maximum longitudinal tilt) is obtained. Since the horizontal distribution of the corresponding oil may change when the oil pan is tilted, the minimum oil storage height in the oil pan is obtained based on the extreme values ​​of the two tilt angles in the oil pan. When obtaining the minimum oil storage height, the maximum lateral tilt oil volume is obtained based on the maximum lateral tilt of the oil pan, and the maximum longitudinal tilt oil volume is obtained based on the maximum longitudinal tilt of the oil pan. The larger value of the maximum lateral tilt oil volume and the maximum longitudinal tilt oil volume is taken, and the larger value is the minimum oil storage height of the oil in the oil pan.

[0077] Step 112-2, obtaining the second minimum oil storage volume in the oil pan according to the minimum oil storage height.

[0078] Based on the obtained minimum oil storage height, the second minimum oil storage volume in the corresponding oil pan can be obtained to facilitate subsequent further operations.

[0079] Specifically, there is no fixed order between step 112 - 1 and step 112 - 2 , and the sequence numbers of step 112 - 1 and step 112 - 2 do not constitute a limitation on the execution order of the two steps.

[0080] In some embodiments of the present application, in step 113, obtaining the minimum oil storage amount by using the first minimum oil storage amount and the second minimum oil storage amount includes:

[0081] Step 113 - 1 , obtaining a first oil storage amount of the engine oil in the oil pan when the lubrication system works normally.

[0082] When the lubrication system is operating normally, the corresponding oil pan is in normal operation, and a first oil storage amount in the oil pan in this case is obtained.

[0083] Step 113-2, obtaining a second oil storage amount of the engine oil in the oil pan after the lubrication system stops working for a set time.

[0084] After the lubrication system stops working and a set time has passed, the amount of oil in the oil pan is in a stable state, and part of the wall-hanging and suspended oil in the corresponding lubrication system will flow into the oil pan, thereby obtaining a second oil level; therefore, it is necessary to stipulate that the time node for obtaining the second oil level is after obtaining the set time when the lubrication system stops working; if the second oil level is obtained immediately after the lubrication system stops working, the value of the second oil level will be too large, and therefore it is necessary to obtain the second oil level after the lubrication system stops working for a set time, at which time the corresponding part of the wall-hanging and suspended oil will fall into the oil pan.

[0085] Step 113 - 3 , obtaining a second suspended wall oil amount according to the first oil storage amount and the second oil storage amount.

[0086] The second suspended wall oil amount is the difference between the first oil storage amount and the second oil storage amount, so the second suspended wall oil amount is the wall-hanging and suspended oil entering the oil pan during the period after the lubrication system stops working for a set time.

[0087] Step 113-4, obtaining the minimum oil storage volume by taking the larger value of the first minimum oil storage volume and the second minimum oil storage volume and the second suspended wall oil volume.

[0088] When considering the minimum oil storage volume, it is necessary to consider the second suspended wall oil volume that enters the oil pan after the lubrication system stops working for a set time. That is, in order to obtain the minimum oil storage volume, it is necessary to first take the larger value of the first minimum oil storage volume and the second minimum oil storage volume, and then add this larger value to the second suspended wall oil volume to obtain the minimum oil storage volume. Here, the calculation formula for the minimum oil storage volume can be listed as:

[0089] Minimum oil storage amount = MAX (first minimum oil storage amount, second minimum oil storage amount) + second suspended wall oil amount.

[0090] In some embodiments of the present application, the lubrication system includes an oil pump, which provides power for the oil to flow in the lubrication system; in step 111, obtaining the initial amount of oil added to the oil pan includes:

[0091] Step 111 - 1 , obtaining the amount of oil pumped by the oil pump within a set time.

[0092] When the oil pump is pumping oil, the initial oil addition amount can be calculated by monitoring the amount of oil pumped by the oil pump within a set time.

[0093] Step 111 - 2 , obtaining the number of cycles of the engine oil in the lubrication system within a set time.

[0094] After obtaining the amount of oil pumped by the oil pump within the set time, it is necessary to determine the number of cycles of the oil pump in the lubrication system within the set time in order to obtain the initial amount of oil added.

[0095] Step 111 - 3, obtaining the initial oil addition amount according to the pump oil amount and the number of cycles.

[0096] After obtaining the initial oil addition amount, the corresponding oil amount can be calculated according to the corresponding formula. The calculation formula for the initial oil addition amount can be:

[0097] Initial oil addition amount = pump oil amount / number of cycles.

[0098] In some embodiments of the present application, in step 111-1, obtaining the oil pumping amount of the oil pump within a set time includes:

[0099] The pump oil volume is obtained by simulation calculation under set conditions. The set conditions include:

[0100] The oil pressure requirements of each lubrication point, the length and inner diameter of each oil channel, the flow pressure difference data of each lubrication structure and the oil parameters used.

[0101] In the lubrication system, when obtaining the pump oil volume, it is necessary to take into account the relevant setting conditions. The setting conditions are the factors that affect the oil volume. Therefore, the setting conditions include: the oil pressure requirements of each lubrication point, which include oil pressure, speed, load and oil temperature; the length and inner diameter of each oil channel, which can be obtained through the 3D oil channel model; the flow pressure difference data of each lubrication structure, which includes pressure difference, flow and oil temperature; the parameters of the oil used, which include viscosity grade and quality grade.

[0102] In some embodiments of the present application, the initial oil addition amount in the oil pan and the first suspended wall oil amount are obtained, and the first suspended wall oil amount includes: the oil storage amount in the oil channel, the oil storage amount in the oil cooler, the oil storage amount in the oil filter, the wall oil storage amount and the suspended oil storage amount.

[0103] Since the first suspended wall oil amount is the amount of oil hanging on the wall and the suspended oil in the lubrication system, the first suspended wall oil amount needs to include the oil storage amount in the oil channel, the oil storage amount in the oil cooler, the oil storage amount in the oil filter, the oil storage amount on the wall and the suspended oil storage amount, etc.

[0104] In some embodiments of the present application, the lubrication system includes a crankshaft connecting rod envelope;

[0105] In step 120, the maximum oil volume in the oil pan is obtained, and the maximum oil volume is obtained by the maximum limit of the engine oil, including:

[0106] Step 121, determining the upper limit of the engine oil by setting a minimum distance between the engine oil level and the crankshaft connecting rod envelope.

[0107] In the prior art, there is a conventional setting for the minimum distance between the engine oil level and the crankshaft connecting rod envelope line to ensure that the engine oil can fully lubricate components such as the crankshaft and connecting rod. In this solution, the distance between the engine oil level and the crankshaft connecting rod envelope line is no less than 8mm, so the corresponding minimum distance set in this solution is 8mm. On the premise of knowing the set minimum distance, the upper limit of the engine oil can be determined based on this distance.

[0108] The minimum distance between the oil level in the lubrication system and the crankshaft connecting rod envelope is limited by the design of the oil dipstick and the dipstick tube and the requirements of the engine during operation. At the same time, this minimum distance is also affected by many factors such as the design and structure of the engine, the lubrication method, the performance of the oil, and the driving conditions. In order to ensure adequate lubrication and stable performance of the engine, the position of the oil level should be set and maintained strictly in accordance with the manufacturer's recommendations and requirements.

[0109] Step 122, obtaining the maximum oil storage amount according to the upper limit of the engine oil.

[0110] After knowing the upper limit of the engine oil, the maximum amount of oil stored in the oil pan can be known accordingly.

[0111] A device, see Figure 2 The device is used to judge the amount of oil added to the lubrication system, the lubrication system includes an oil pan, and the device includes a first oil amount detection module 210, a second oil amount detection module 220 and a judgment module 230:

[0114] The judgment module 230 is used to obtain the oil storage range of the oil pan according to the minimum oil storage amount and the maximum oil storage amount; and obtain the oil volume range that needs to be added to the oil pan according to the oil storage range.
