Description

[0001] This application relates to the field of transmission technology, and in particular to a transmission lubricant quantity assessment device, method, computer equipment, and storage medium. Background Technology

[0002] The transmission is a crucial component of a vehicle's drivetrain. Its primary function is to safely and reliably transmit power by shifting between different gears. During power transmission, the transmission gears generate a significant amount of heat, which needs to be carried away by lubricating oil and exchanged with the outside air through the transmission housing. The amount of transmission lubricating oil is a core indicator for evaluating the lubrication performance of the transmission gears. Furthermore, the lifespan of the transmission is closely related to the amount of lubricating oil. Currently, both domestic and international automotive transmissions experience situations where the transmission lubricating oil level is low during actual use. Prolonged occurrence of this condition will affect the transmission's performance and lifespan.

[0003] To address this issue, transmissions undergo bench testing before being installed in actual vehicles.

Therefore, the exemplary terms “below” and “under” can include both above and below orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0051] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element.

[0053] In one embodiment, such as Figure 1 As shown, this application provides a transmission lubricant quantity assessment device. The transmission lubricant quantity assessment device includes: a simulation component 100, a transmission 200, a temperature measurement component 300, and a control component 400.

[0054] The simulation component 100 simulates the target load conditions of the vehicle, which may include engine speed, torque, and driving resistance during vehicle operation. The transmission 200 is connected to the simulation component 100 and operates at the target transmission gear under the drive of the simulation component 100. The temperature measurement component 300 measures the first temperature information of the lubricating oil in the transmission 200 under various candidate lubricating oil amounts, and the second temperature information of the transmission gears under various candidate lubricating oil amounts. The control component 400 is connected to the temperature measurement component 300 and determines the optimal lubricating oil amount for the target transmission gear based on the first and second temperature information for each candidate lubricating oil amount.

[0055] It is understandable that after the user determines the target gear of the transmission, the target load conditions such as engine speed, torque and vehicle driving resistance that the simulation component 100 should simulate are determined according to the target gear. The target load conditions are simulated by the simulation component 100 so that the transmission 200 works in the target gear under the drive of the simulation component 100.

[0056] In the application, the transmission 200 is connected to the simulation component 100. When the transmission 200 is engaged in the target gear and the amount of lubricating oil in the transmission 200 reaches the target value, the simulation component 100 is activated. The transmission 200 then operates in the target gear under the drive of the simulation component 100. When the first temperature information of the lubricating oil in the transmission 200 reaches the first preset temperature and the second temperature information of the transmission gears reaches the second preset temperature, the simulation component 100 is adjusted to simulate the engine's idling mode, thereby cooling the lubricating oil and transmission gears in the transmission 200. After the first temperature information of the lubricating oil and the second temperature information of the transmission gears drop to the third preset temperature, the target value of the lubricating oil in the transmission 200 is adjusted. The above operation is repeated until all candidate lubricating oil amounts have been tested. Based on the first and second temperature information of each candidate lubricating oil amount, the optimal lubricating oil amount matching the target gear is determined.

[0057] The aforementioned transmission lubricant quantity assessment device connects the transmission to a simulation component, causing the transmission to operate in a target gear under the drive of the simulation component. A temperature measurement component measures the first temperature of the transmission lubricant under various candidate lubricant quantities and the second temperature of the transmission gears under the same conditions. The device analyzes these temperatures and determines the optimal lubricant quantity based on the first and second temperature information. This optimal lubricant quantity is the most suitable for the target gear. Using this transmission lubricant quantity assessment device, the optimal lubricant quantity for different gears can be determined. Furthermore, based on the optimal lubricant quantity for each gear, the most suitable lubricant quantity for the transmission can be accurately assessed, thereby protecting the transmission's performance and extending its service life.

[0058] In one embodiment, such as Figure 2 As shown, the analog component 100 includes an input motor 101 and an output motor 102.

[0059] The input motor 101 is connected to the transmission 200 to simulate the engine speed and torque, driving the transmission 200 to work at the simulated speed and torque.

[0060] The output motor 102 is used to simulate the driving resistance of a vehicle.

[0061] In the application, the input end of the transmission 200 can be connected to the input motor 101 via the bracket 500, and the output end of the transmission 200 is connected to the output motor 102. After the transmission 200 is engaged in the target gear and lubricating oil is added to the transmission, the input motor 101 and the output motor 102 are started. The input motor 101 can simulate the engine speed and torque, and the output motor 102 can simulate the vehicle's driving resistance, so that the transmission 200 works under simulated load conditions. This makes the matching degree between the transmission lubricating oil and the transmission working gear 202 measured in the bench verification stage closer to the matching degree between the transmission lubricating oil and the transmission working gear 202 during the actual operation of the vehicle.

[0062] In one embodiment, the transmission includes a plurality of gears, wherein each gear corresponds to a different transmission gear, the gear corresponding to the transmission gear is a working gear, and the target transmission gear is one of the transmission gears.

[0063] The control component 400 is also used to obtain the optimal lubricating oil quantity for each transmission gear and determine the target lubricating oil quantity based on the optimal lubricating oil quantity for each transmission gear.

[0064] It is understood that the transmission 200 contains multiple gears, each corresponding to a different gear position. During vehicle operation, the transmission gears need to be adjusted to change the vehicle speed. By connecting the transmission 200 to the simulation component 100, when the transmission 200 is engaged in the target gear and the amount of lubricating oil in the transmission 200 reaches a candidate lubricating oil level, the transmission 200 operates under the drive of the simulation component 100. The temperature measurement component 300 detects the first and second temperature information at this candidate lubricating oil level. When the first temperature of the lubricating oil in the transmission 200 reaches a first preset temperature, and the second temperature of the transmission working gear 202 reaches a second preset temperature, the simulation component 100 is adjusted to simulate the engine's idling mode, thereby cooling the lubricating oil in the transmission 200 and the transmission working gear 202. After the first temperature of the lubricating oil in the transmission 200 and the second temperature of the transmission working gear 202 drop to a third preset temperature, the lubricating oil in the transmission 200 is adjusted to another candidate lubricating oil quantity, and the above operation is repeated until all candidate lubricating oil quantities have been tested. Based on the first and second temperature information under each candidate lubricating oil quantity, the optimal lubricating oil quantity matching the target gear is determined. Then, by adjusting the target gear of the transmission 200, the above operation is repeated until the optimal lubricating oil quantity corresponding to each gear is determined, and then the target lubricating oil quantity can be determined by combining the optimal lubricating oil quantities corresponding to each gear. The target lubricant quantity can be determined comprehensively based on factors such as the frequency of transmission gear usage and the main purpose of the vehicle, according to historical data. For example, the usage frequency of each transmission gear within a predetermined time period can be obtained, and the gear with the highest usage frequency can be identified as the target transmission gear, with the optimal lubricant quantity corresponding to the target transmission gear being determined as the target lubricant quantity. Alternatively, the percentage of times each transmission gear is used within a predetermined time period can be obtained, and this percentage can be determined as its corresponding weight. The target lubricant quantity is then determined based on the weight of each transmission gear and the optimal lubricant quantity. The percentage of times a transmission gear is used represents the proportion of the number of times a particular transmission gear is used within a unit of time to the total number of times all transmission gears are used within the same unit of time.

[0065] For example, a transmission has three gears: A, B, and C. Within a predetermined period of one week, gear A is used 20 times, and the optimal lubricant quantity for gear A is 5L; gear B is used 45 times, and the optimal lubricant quantity for gear B is 6L; gear C is used 30 times, and the optimal lubricant quantity for gear C is 7L. Then, gear B, which has the highest usage frequency, is determined as the target transmission gear, and the optimal lubricant quantity of 7L for the target transmission gear is determined as the target lubricant quantity. Again, for example, a transmission has three gears: A, B, and C. Within a predetermined period of one week, gear A is used 20% of the time, and the optimal lubricant quantity for gear A is 5L; gear B is used 50% of the time, and the optimal lubricant quantity for gear B is 6L; gear C is used 30% of the time, and the optimal lubricant quantity for gear C is 7L. The usage frequency of each gear is then determined as the corresponding weight. Based on the weight of each gear and the optimal lubricating oil quantity, the target lubricating oil quantity is determined to be 20%*5+50%*6+30%*7=6.1L.

[0066] In one embodiment, such as Figure 2 As shown, the temperature measurement component 300 includes: a first temperature sensor and a second temperature sensor 301.

[0067] The first temperature sensor is connected to the control component 400 and is used to measure the first temperature information of the lubricating oil in the transmission 200 under various candidate lubricating oil quantities.

[0068] The second temperature sensor 301 is connected to the control component 400 and is used to measure the second temperature information of the transmission working gear 202 under various candidate lubricating oil quantities.

[0069] In application, if the amount of lubricating oil in the transmission 200 is too low, the heat on the gear surface cannot be adequately carried away by the lubricating oil, resulting in high gear surface temperature and accelerated gear wear. Conversely, if the amount of lubricating oil in the transmission 200 is too high, it will cause excessive heat generation in the gears, leading to excessively high gearbox temperature. This will also accelerate lubricating oil deterioration and further exacerbate gear wear. Therefore, when the amount of lubricating oil in the transmission is mismatched with the working gears, the temperature of both the lubricating oil and the working gears 202 will be excessively high, accelerating gear wear.

[0070] It is understandable that when the transmission 200 is engaged in the target gear and the amount of lubricating oil in the transmission 200 reaches the target value, the simulation component 100 drives the transmission 200 to work in the target gear. The first temperature sensor measures the first temperature information of the lubricating oil in the transmission 200 under various candidate lubricating oil amounts, and the second temperature sensor 301 measures the second temperature information of the transmission working gear 202 under various candidate lubricating oil amounts. By obtaining the first temperature information of the lubricating oil in the transmission 200 and the second temperature information of the transmission working gear 202 under various candidate lubricating oil amounts in the target gear, the matching degree between each candidate lubricating oil amount and the target gear can be analyzed, and the optimal lubricating oil amount that best matches the target gear can be determined.

[0071] In one embodiment, such as Figure 2 As shown, the control component 400 also includes: a working condition adjustment element and a lubricating oil quantity determination element.

[0072] The operating condition adjustment element is connected to the simulation component 100 and is used to control the state parameters of the simulation component 100 to adjust the load conditions simulated by the simulation component 100. The operating condition adjustment element can be a torque measurement unit 401. The state parameters include rolling resistance F. f air resistance F w Slope resistance F i and acceleration resistance F j .

[0073] The transmission 200 is mounted on the bracket 500. The input end of the transmission 200 is connected to the input motor 101, and the output end of the transmission 200 is connected to the torque measuring unit 401 and the output motor 102 via the drive shaft 600. The torque measuring unit 401 includes a rolling resistance F. f air resistance F w Slope resistance F i and acceleration resistance F j The setting module. Since the load conditions corresponding to each target gear of the transmission 200 are different, the speed and torque of the input motor 101 and the driving resistance ∑F of the output motor 102 can be dynamically adjusted in real time by adjusting the parameters of each setting module, so as to adjust the simulated load conditions of the input motor 101 and the output motor 102. By adjusting the parameters of each setting module, the load conditions of the transmission 200 under each target gear can be simulated, so that the matching degree between the transmission lubricating oil and the transmission working gear 202 measured in the bench verification stage is closer to the matching degree between the transmission lubricating oil and the transmission working gear 202 during actual vehicle operation. Wherein, ∑F=F f +F w +F i +F j .

[0074] The lubricating oil quantity determination element determines a first temperature curve for each candidate lubricating oil quantity based on first temperature information, determines a second temperature curve for each candidate lubricating oil quantity based on second temperature information, determines the temperature difference between the first and second temperature information for each candidate lubricating oil quantity, and determines the optimal lubricating oil quantity for the target transmission gear based on the temperature difference information. The lubricating oil quantity determination element may include a wireless receiver 402.

[0075] In the application, multiple temperature difference intervals and multiple equilibrium time intervals can be set. A weight X is assigned to the temperature difference, and a weight Y is assigned to the equilibrium time. Corresponding evaluation scores are set for each temperature difference interval and equilibrium time interval. The final score is the sum of the product of the evaluation score corresponding to the temperature difference for each candidate lubricating oil quantity and the weight X of the temperature difference, and the product of the evaluation score corresponding to the equilibrium time and the weight Y of the equilibrium time. Finally, the optimal lubricating oil quantity is determined from among the candidate lubricating oil quantities based on the final score of each candidate lubricating oil quantity. Where X + Y = 1.

[0076] For example, the temperature difference is weighted at 0.6, and the balancing time is weighted at 0.4. When the balancing time between the transmission oil temperature and the transmission gear temperature is less than 60 minutes, the corresponding oil quantity score is 100; when the balancing time is between 60 and 90 minutes, the corresponding oil quantity score is 80; when the balancing time is between 90 and 120 minutes, the corresponding oil quantity score is 60; and when the balancing time is more than 120 minutes, the corresponding oil quantity score is 40. When the temperature difference between the transmission lubricating oil and the transmission working gears is 0℃-2℃, the corresponding score for the lubricating oil quantity is 100; when the temperature difference is 2℃-4℃, the corresponding score for the lubricating oil quantity is 80; when the temperature difference is 4℃-6℃, the corresponding score for the lubricating oil quantity is 60; and when the temperature difference is greater than 6℃, the corresponding score for the lubricating oil quantity is 40. When the candidate lubricating oil quantities for the target transmission gear are 5L and 6L, if the candidate lubricating oil quantity is 5L, the equilibrium time between the transmission lubricating oil temperature and the transmission working gear temperature is 70 minutes, and the temperature difference between the transmission lubricating oil and the transmission working gear is 1℃, then the final score for the candidate lubricating oil quantity of 5L is 0.6*100+0.4*80=92; if the candidate lubricating oil quantity is 6L, the equilibrium time between the transmission lubricating oil temperature and the transmission working gear temperature is 55 minutes, and the temperature difference between the transmission lubricating oil and the transmission working gear is 3℃, then the final score for the candidate lubricating oil quantity of 6L is 0.6*80+0.4*100=88. Therefore, when the candidate lubricating oil quantities are 5L and 6L, the candidate lubricating oil quantity of 5L is the optimal lubricating oil quantity that best matches the target transmission gear.

[0077] It can be understood that by measuring the first temperature information of the lubricating oil in the transmission 200 under various candidate lubricating oil quantities using a first temperature sensor, and measuring the second temperature information of the transmission working gear 202 under various candidate lubricating oil quantities using a second temperature sensor 301, the first temperature information of the lubricating oil in the transmission 200 and the second temperature information of the transmission working gear 202 under various candidate lubricating oil quantities for the target gear can be obtained. The lubricating oil quantity determining element can then determine the first temperature curve of the target gear under each candidate lubricating oil quantity based on the first temperature information of the target gear under each candidate lubricating oil quantity, and determine the second temperature curve of the target gear under each candidate lubricating oil quantity based on the second temperature information of the target gear under each candidate lubricating oil quantity. By analyzing the temperature curves, the temperature difference information between the first and second temperature information can be obtained. The temperature difference information includes the temperature difference after the first and second temperature information are balanced and the balance time between the first and second temperature information. Based on the analyzed temperature difference information, and through pre-set weights and evaluation scores, the final score for each candidate lubricant quantity can be calculated. A higher final score indicates a higher degree of matching between the candidate lubricant quantity and the target gear. By comparing the final scores, the optimal lubricant quantity for the target transmission gear can be determined. Furthermore, the optimal lubricant quantity for each target gear of the transmission can be determined. Combining this with factors such as vehicle usage, the target lubricant quantity best matched to the transmission can be comprehensively determined, thereby protecting the transmission's performance and extending its service life.

[0078] In one embodiment, such as Figure 2 As shown, the temperature measurement component 300 also includes a wireless transmitter 302.

[0079] The wireless transmitter 302 is located on the gearbox 200 and connected to the control component 400, and is used to receive the second temperature information measured by the temperature measurement component 300.

[0080] The control component 400 also includes a wireless receiver 402.

[0081] The wireless receiver 402 is used to receive each first temperature information and each second temperature information, and to plot the first temperature curve of the transmission lubricating oil under each candidate lubricating oil amount, and the second temperature curve of the transmission gear under each candidate lubricating oil amount.

[0082] In the application, the wireless transmitter 302 is connected to the second temperature sensor 301 to receive the second temperature information measured by the temperature measurement component 300 and transmit the second temperature information to the wireless receiver 402. Simultaneously, the first temperature sensor located within the transmission 200 directly transmits the detected first temperature information of the lubricating oil within the transmission 200 to the wireless receiver 402. After receiving the first and second temperature information, the wireless receiver 402 can generate a first temperature curve for the transmission lubricating oil at various candidate lubricating oil amounts, and a second temperature curve for the transmission gears 202 at various candidate lubricating oil amounts. By transmitting the received second temperature information measured by the temperature measurement component 300 to the wireless receiver 402 via the wireless transmitter 302, the second temperature information can be transmitted in real time even during the operation of the transmission gears 202, ensuring the reliability and effectiveness of the second temperature information transmission.

[0083] In one embodiment, such as Figure 3 As shown, the second temperature sensor 301 includes a detection head 303 and a signal transmission line. The surface of the gear is provided with a mounting hole, and the detection head 303 is disposed in the mounting hole.

[0084] The transmission 200 also includes an output shaft 203 and an output flange 201. The output shaft 203 is connected to the transmission gear, and the surface of the output shaft 203 is provided with grooves. The signal transmission line is located in the grooves and extends along the grooves. The transmission output flange 201 is provided with a connecting through hole, which communicates with the grooves. The signal transmission line passes through the connecting through hole and connects to the wireless transmitter 302.

[0085] It is understandable that before assembling the transmission 200, holes should be drilled on the surface of the transmission gears, grooves should be drilled on the surface of the transmission output shaft 203, and holes should be drilled in the transmission output flange 201. The detection head 303 and signal transmission line of the second temperature sensor 301 should be arranged in the shaft gear so that the detection head 303 can detect the second temperature information of the transmission working gear 202. It can be sealed with high temperature and oil resistant glue to prevent the detection head 303 and signal transmission line of the second temperature sensor 301 from being damaged during the operation of the transmission working gear 202. At the same time, the signal transmission line of the second temperature sensor 301 should be led out to the outer end of the transmission 200 and connected to the wireless transmitter 302 so that the second temperature sensor 301 can transmit the second temperature information of the transmission working gear 202 to the wireless transmitter 302, and then the wireless transmitter 302 will send the second temperature information of the transmission working gear 202 to the wireless receiver 402.

[0086] Based on the above embodiments, in one embodiment, such as Figure 2As shown, the transmission lubricating oil level assessment device includes: an input motor 101, an output motor 102, a transmission 200, a first temperature sensor, a second temperature sensor 301, a wireless transmitter 302, a torque measurement unit 401, and a lubricating oil level determination element. The lubricating oil level determination element may include a wireless receiver 402.

[0087] The input motor 101 is connected to the transmission 200 to simulate the engine's speed and torque, driving the transmission 200 to operate at the simulated speed and torque. The output motor 102 is used to simulate the vehicle's driving resistance.

[0088] The input motor 101 is located at the front end of the bracket 500. The input motor 101 is used to simulate the speed and torque of the engine. The bracket 500 is used to mount the transmission 200. The input end of the transmission is connected to the input motor 101. The output end of the transmission 200 is connected to the torque measurement unit 401 and the output motor 102 through the drive shaft 600. The output motor 102 is located at the rear end of the torque measurement unit 401. The output motor 102 can simulate the driving resistance of a car. The torque measurement unit 401 can adjust the speed and torque of the input motor 101 and the driving resistance of the output motor 102.

[0089] The transmission 200 includes multiple gears, each gear corresponding to a different transmission gear. The gear corresponding to the transmission gear is a working gear, and the target transmission gear is one of the transmission gears. The transmission 200 is used to operate in the target transmission gear under the drive of the simulation component 100.

[0090] A first temperature sensor is connected to a wireless receiver 402 to measure the first temperature information of the lubricating oil in the transmission 200 under various candidate lubricating oil amounts. A second temperature sensor 301 is connected to the wireless receiver 402 to measure the second temperature information of the transmission working gear 202 under various candidate lubricating oil amounts. A wireless transmitter 302 is located on the transmission 200 and connected to the wireless receiver 402 to receive the second temperature information measured by the second temperature sensor 301. The second temperature sensor 301 includes a detection head 303 and a signal transmission line. The surface of the transmission gear has a mounting hole, and the detection head 303 is disposed in the mounting hole. The transmission 200 also includes an output shaft and an output flange. The output shaft is connected to the transmission gear, and the surface of the output shaft has a groove. The signal transmission line is located in the groove and extends along the groove. The transmission output flange 201 has a connecting through hole that communicates with the groove. The signal transmission line passes through the connecting through hole and connects to the wireless transmitter 302.

[0091] A first temperature sensor is installed inside the transmission 200. The first temperature sensor can collect the temperature of the lubricating oil inside the transmission 200 in real time and send the first temperature information to the wireless receiver 402. The second temperature sensor 301 includes a detection head 303, which is mounted on the surface of the transmission working gear 202. The signal transmission line of the second temperature sensor 301 is led out to the outside of the transmission 200 and connected to the wireless transmitter 302, so that the second temperature information of the transmission working gear 202 detected by the second temperature sensor 301 is transmitted to the wireless transmitter 302. The wireless transmitter 302 is fixed on the transmission output flange 201, and the second temperature information transmitted by the wireless transmitter 302 is received by the wireless receiver 402.

[0092] With the transmission 200 engaged in the target gear and the target lubricating oil value added to the transmission 200, the parameters of the torque measurement unit 401 setting module are set to adjust the speed and torque of the input motor 101 and the driving resistance of the output motor 102, simulating the load condition of the transmission 200 in the target gear. After the parameters of the torque measurement unit 401 setting module are set, the input motor 101 and the output motor 102 are started, and the transmission 200 can then work in the target gear under the drive of the input motor 101 and the output motor 102. The first temperature sensor directly sends the first temperature information of the lubricating oil in the transmission 200 to the wireless receiver 402. The second temperature sensor 301 detects the temperature of the transmission working gear 202 through the detection head 303 and sends the second temperature information of the transmission working gear 202 detected through the wireless transmitter 302 to the wireless receiver 402.

[0093] When the first temperature of the lubricating oil in the transmission 200 reaches a first preset temperature and the second temperature of the transmission working gear 202 reaches a second preset temperature, the parameters of the torque measurement unit 401 setting module are adjusted to simulate an idle mode for the input motor 101 and output motor 102, thereby cooling the lubricating oil in the transmission 200 and the transmission working gear 202. Simultaneously, the wireless receiver records the first temperature of the lubricating oil in the transmission 200 and the second temperature of the transmission working gear 202, and plots and records the first temperature curve of the lubricating oil in the transmission 200 and the second temperature curve of the transmission working gear 202 based on these temperature information. After the first temperature of the lubricating oil in the transmission 200 and the second temperature of the transmission working gear 202 drop to a third preset temperature, the target value of the lubricating oil in the transmission 200 is adjusted, and the above operation is repeated until the quantities of all candidate lubricating oils have been tested. By analyzing the first temperature curve of the lubricating oil in the transmission 200 under various candidate lubricating oil amounts and the second temperature curve of the transmission working gear 202 under various candidate lubricating oil amounts, the temperature difference and temperature equilibrium time of the lubricating oil in the transmission 200 and the transmission gear are analyzed to obtain the optimal lubricating oil amount that best matches the target gear.

[0094] Based on the same inventive concept, such as Figure 4 As shown, this application also provides a method for evaluating the quantity of transmission lubricating oil, which includes:

[0095] S401: When the transmission is operating in the target transmission gear under the drive of the simulation component, acquire the first temperature information of the lubricating oil in the transmission under multiple candidate lubricating oil amounts, and the second temperature information of the transmission working gears under multiple candidate lubricating oil amounts, wherein the simulation component is used to simulate the target load condition.

[0096] S402: Determine the optimal lubricating oil quantity for the target transmission gear based on the first and second temperature information for each candidate lubricating oil quantity.

[0097] The transmission lubricant quantity assessment method can be applied to the transmission lubricant quantity assessment device described in any of the above embodiments.

[0098] In the application, the transmission 200 is connected to the simulation component 100. When the transmission 200 is engaged in the target gear and the amount of lubricating oil in the transmission 200 reaches the target value, the simulation component 100 is activated, and the transmission can then operate in the target gear under the drive of the simulation component 100. When the first temperature information of the lubricating oil in the transmission 200 reaches the first preset temperature and the second temperature information of the transmission working gear 202 reaches the second preset temperature, the simulation component 100 is adjusted to simulate the engine idling mode, so as to cool down the lubricating oil in the transmission 200 and the transmission working gear 202. After the first temperature information of the lubricating oil in the transmission 200 and the second temperature information of the transmission working gear 202 drop to the third preset temperature, the target value of the lubricating oil in the transmission 200 is adjusted, and the above operation is repeated until all candidate lubricating oil amounts have been tested. Based on the first and second temperature information of each candidate lubricating oil amount, the optimal lubricating oil amount matching the target gear is determined.

[0099] The aforementioned transmission lubricant quantity assessment method acquires first temperature information of the transmission lubricant under multiple candidate lubricant quantities, and second temperature information of the transmission working gears under multiple candidate lubricant quantities. Based on the first and second temperature information for each candidate lubricant quantity, it determines the optimal lubricant quantity for the target transmission gear, thus finding the lubricant quantity that best matches the target gear. Therefore, based on this method, the optimal lubricant quantity for different transmission gears can be determined, and the optimal lubricant quantity for each gear can be accurately assessed to determine the lubricant quantity that best matches the transmission, thereby protecting the transmission's performance and extending its service life.

[0100] In one embodiment, the method for evaluating transmission lubricating oil quantity further includes the steps of: obtaining the optimal lubricating oil quantity for each of the transmission gears, and determining the target lubricating oil quantity based on the optimal lubricating oil quantity for each of the transmission gears.

[0101] It is understood that the transmission 200 contains multiple gears, each corresponding to a different gear. During vehicle operation, the gear needs to be adjusted to change the vehicle's speed. By connecting the transmission 200 to the simulation component 100, the transmission 200 can operate under the drive of the simulation component 100 when the target gear is engaged and the amount of lubricating oil in the transmission reaches the target value. When the first temperature information of the lubricating oil in the transmission 200 reaches the first preset temperature and the second temperature information of the transmission working gear 202 reaches the second preset temperature, the simulation component 100 is adjusted to simulate the engine's idling mode, thereby cooling the lubricating oil in the transmission 200 and the transmission working gear 202. After the first temperature information of the lubricating oil in the transmission 200 and the second temperature information of the transmission working gear 202 drop to the third preset temperature, the target value of the lubricating oil in the transmission 200 is adjusted, and the above operation is repeated until all candidate lubricating oil amounts have been tested. Based on the first and second temperature information of each candidate lubricating oil amount, the optimal lubricating oil amount matching the target gear is determined. Then, by adjusting the target gear of the transmission, repeat the above operation until all the target gears to be tested have been tested. Then, the optimal lubricating oil quantity for each target gear can be obtained. Finally, the target lubricating oil quantity of the transmission can be determined by combining the optimal lubricating oil quantity corresponding to each gear.

[0102] In one embodiment, determining the optimal lubricating oil quantity for a target transmission gear based on first temperature information and second temperature information for each candidate lubricating oil quantity includes: determining a first temperature curve for each candidate lubricating oil quantity based on the first temperature information for each candidate lubricating oil quantity; determining a second temperature curve for each candidate lubricating oil quantity based on the second temperature information for each candidate lubricating oil quantity; determining temperature difference information between the first temperature information and the second temperature information for each candidate lubricating oil quantity based on the first temperature curve and the second temperature curve; and determining the optimal lubricating oil quantity for the target transmission gear based on the temperature difference information for each candidate lubricating oil quantity.

[0103] It can be understood that by measuring the first temperature information of the lubricating oil in the transmission under various candidate lubricating oil quantities using a first temperature sensor, and measuring the second temperature information of the transmission working gear 202 under various candidate lubricating oil quantities using a second temperature sensor 301, the first temperature information of the lubricating oil in the transmission 200 and the second temperature information of the transmission working gear 202 under various candidate lubricating oil quantities for the target gear can be obtained. The lubricating oil quantity determining element can then determine the first temperature curve of the target gear under each candidate lubricating oil quantity based on the first temperature information of the target gear under each candidate lubricating oil quantity, and determine the second temperature curve of the target gear under each candidate lubricating oil quantity based on the second temperature information of the target gear under each candidate lubricating oil quantity. By analyzing the temperature curves, the temperature difference information between the first and second temperature information can be obtained. The temperature difference information includes the temperature difference after the first and second temperature information are balanced and the balance time between the first and second temperature information.

[0104] Based on the analyzed temperature difference information, and through pre-set weights and evaluation scores, the final score for each candidate lubricant quantity can be calculated. A higher final score indicates a higher degree of matching between the candidate lubricant quantity and the target gear. By comparing the final scores, the optimal lubricant quantity for the target transmission gear can be determined. Furthermore, the optimal lubricant quantity for each target gear of the transmission can be determined. Combining this with factors such as vehicle usage, the most suitable lubricant quantity for the transmission can be comprehensively determined, thereby protecting the transmission's performance and extending its service life.

[0105] In one embodiment, the transmission lubricant quantity assessment method further includes: acquiring first temperature information and second temperature information, and plotting a first temperature curve of the transmission lubricant at each candidate lubricant quantity based on the first temperature information of the transmission lubricant at each candidate lubricant quantity detected by the first temperature sensor; and plotting a second temperature curve of the transmission working gear at each candidate lubricant quantity based on the second temperature information of the transmission working gear at each candidate lubricant quantity detected by the second temperature sensor and transmitted to the wireless transmitter.

[0106] In the application, by acquiring the first temperature information of the transmission lubricating oil under each candidate lubricating oil quantity detected by the first temperature sensor and the second temperature information of the transmission working gear 202 under each candidate lubricating oil quantity detected by the second temperature sensor 301 and transmitted to the wireless transmitter 302, the wireless receiver 402 can plot the first temperature curve of the transmission lubricating oil under each candidate lubricating oil quantity and the second temperature curve of the transmission working gear 202 under each candidate lubricating oil quantity. By analyzing the temperature curves, the temperature difference information between the first and second temperature information is obtained. Based on the analyzed temperature difference information, and through pre-set weights and evaluation scores, the final score of each candidate lubricating oil quantity can be calculated. The larger the final score, the higher the matching degree between the candidate lubricating oil quantity corresponding to the final score and the target gear. By comparing the size of the final scores, the optimal lubricating oil quantity of the target transmission gear can be obtained. Furthermore, the optimal lubricating oil quantity of each target gear of the transmission can be obtained. Combined with factors such as vehicle usage, the most suitable lubricating oil quantity for the transmission can be comprehensively determined, thereby protecting the performance of the transmission and extending its service life.
