Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to methods, apparatus, equipment and media for determining the efficiency of a user's driving vehicle assembly. Background Technology

[0002] Currently, many assembly full-condition efficiency tests are conducted on a test bench simulating WLTC / NEDC, measuring input and output torque and speed. This method has two problems: First, WLTC / NEDC conditions only represent the operating conditions of most users and cannot differentiate between the common road conditions of users in different regions. Second, because the torque coverage of assemblies is large, single-range torque and speed sensors are generally used during testing. To cover the full torque and speed range, large-range torque and speed sensors are selected, resulting in inaccurate determination of the vehicle's assembly efficiency and consequently, an inability to accurately match the corresponding optimization strategy to the user's vehicle. Therefore, improving the accuracy of determining the user's vehicle assembly efficiency has become a significant technical challenge. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a method, apparatus, equipment and medium for determining the efficiency of a user's vehicle assembly.

[0006] For each of the aforementioned regional operating conditions, multiple input torque characteristic information and multiple input speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the input power of the driving vehicle under the regional operating conditions.

[0007] For each of the aforementioned regional operating conditions, multiple output torque characteristic information and multiple output speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the output power of the driving vehicle under the regional operating conditions.

[0008] Based on the input power and output power of the driving vehicle under each of the aforementioned regional operating conditions, the overall efficiency of the driving vehicle under multiple regional operating conditions is determined.

[0009] In one possible implementation, for each of the aforementioned regional operating conditions, multiple input torque characteristic information and multiple input speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the input power of the driving vehicle under the regional operating conditions, including:

[0010] For each input torque feature, it is detected whether the input torque feature is less than the first torque information. If it is greater than the first torque information, it is detected whether the input torque feature is less than the second torque information. If it is greater than the second torque information, the target input torque feature under the working conditions of this region is determined based on the first torque sensor; wherein, the first torque information is less than the second torque information.

[0011] For each input speed characteristic information, it is detected whether the input speed characteristic information is less than the first speed information. If so, the target input speed characteristic information under the working conditions of this region is determined according to the first speed sensor.

[0014] If the input torque characteristic information is less than the first torque information, then the target input torque characteristic information under the working conditions of this region is determined based on the second torque sensor.

[0015] If the input torque characteristic information is less than the second torque information, the target input torque characteristic information under the working conditions of this region is determined according to the third torque sensor; wherein, the torque measurement range of the first torque sensor, the second torque sensor and the third torque sensor decreases in sequence.

[0016] In one possible implementation, determining the vehicle's overall efficiency under multiple regional operating conditions based on the vehicle's input and output power for each of the regional operating conditions includes:

[0022] The target optimization strategy for the vehicle corresponding to the overall efficiency of the vehicle is selected from a set of preset vehicle optimization strategies.

[0023] In one possible implementation, the operating state of the driving vehicle is determined by the following steps;

[0024] The vibration data of the drive axle package of the vehicle being driven is detected to see if it exceeds a preset vibration value during driving.

[0025] If the vibration exceeds the preset value, the vehicle's operating state is abnormal.

[0026] If the preset vibration value is not exceeded, then the temperature of the lubricating oil in the gear contact area of ​​the drive axle housing of the driving vehicle is detected to be within the preset temperature range during driving.

[0027] If the temperature is not within the preset temperature range, the vehicle is not operating properly.

[0028] If the temperature is within the preset range, the vehicle is operating normally.

[0029] In one possible implementation, the step of performing feature processing on multiple real-time vehicle data information under different regional operating conditions to determine vehicle characteristic information under different regional operating conditions includes:

[0030] Multiple real-time vehicle data information under different regional operating conditions are input into a pre-trained neural network model, and features are extracted from the multiple real-time vehicle data information under different regional operating conditions to determine the vehicle feature information under different regional operating conditions.

[0049] In order to enable those skilled in the art to use the content of this application and combine it with the specific application scenario of "determining the efficiency of the driving vehicle assembly", the following implementation method is given. For those skilled in the art, the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application.

[0050] First, the applicable scenarios for this application will be introduced. This application can be applied to the field of automotive technology.

[0051] Research has revealed that current full-condition efficiency tests for many vehicle assemblies are conducted on test benches simulating WLTC / NEDC standards by measuring input and output torque and speed. This method has two problems: First, WLTC / NEDC standards only represent the operating conditions of most users and cannot differentiate between the common road conditions experienced by users in different regions. Second, because the torque range of vehicle assemblies is large, tests typically use single-range torque and speed sensors. To cover the full torque and speed range, large-range torque and speed sensors are often selected, leading to inaccurate determinations of the vehicle's overall efficiency and consequently, an inability to accurately match the user's vehicle with the appropriate optimization strategy. Therefore, improving the accuracy of determining the user's vehicle's overall efficiency has become a significant technical challenge.

[0052] Based on this, the embodiments of this application provide a method for determining the efficiency of a user's vehicle assembly. By extracting the user's driving habits under different regional operating conditions, and providing conditions for subsequent customization of vehicle assembly efficiency for different regional operating conditions, the determination of vehicle assembly efficiency is more accurate. By measuring torque and speed in segments, the accuracy of assembly efficiency determination is improved.

[0053] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for determining the efficiency of a user's driving vehicle assembly, provided as an embodiment of this application. Figure 1 As shown in the embodiments of this application, the method for determining the efficiency of a driving vehicle assembly includes:

[0054] S101: Determine the operating status of the user's vehicle during driving, acquire multiple real-time vehicle data information of the vehicle under different regional operating conditions when the operating status is normal, perform feature processing on the multiple real-time vehicle data information under different regional operating conditions, and determine the vehicle feature information under different regional operating conditions.

[0055] In this step, the working status of the user's vehicle during driving is determined, and multiple real-time vehicle data information of the vehicle with normal working status under different regional working conditions is obtained. Feature processing is performed on the multiple real-time vehicle data information under different regional working conditions to determine the vehicle feature information under different regional working conditions.

[0056] Here, regional operating conditions include urban operating conditions, suburban operating conditions, mountainous operating conditions, and comprehensive operating conditions.

[0057] Among them, real-time vehicle data information includes input torque information, output torque information, input speed information, and output speed information when driving the vehicle under different regional operating conditions.

[0058] In one possible implementation, the operating state of the driving vehicle is determined through the following steps:

[0059] A: Detect whether the vibration data of the drive axle package of the vehicle exceeds the preset vibration value during driving.

[0060] Here, the vibration data of the drive axle package of the vehicle being driven is detected to see if it exceeds the preset vibration value.

[0061] B: If the vibration exceeds the preset value, the vehicle is not operating properly; if the vibration does not exceed the preset value, the temperature of the lubricating oil in the gear contact area of ​​the drive axle housing of the vehicle is checked to see if it is within the preset temperature range during driving.

[0062] Here, if the vibration exceeds the preset value, the vehicle's operating condition is abnormal; if it does not exceed the preset vibration value, the temperature of the lubricating oil in the gear contact area of ​​the drive axle housing of the vehicle is checked to see if it is within the preset temperature range during driving.

[0063] The preset temperature range is 80±10℃.

[0064] C: If the temperature is not within the preset temperature range, the vehicle is not operating normally; if the temperature is within the preset temperature range, the vehicle is operating normally.

[0065] If the temperature is outside the preset range, the vehicle will not function properly; if it is within the preset range, the vehicle will function normally.

[0066] In a specific embodiment, a temperature sensor is installed on the drive axle housing to detect the temperature of the lubricating oil in the gear contact area within the drive axle housing. The temperature sensor is directly aligned with the contact area of ​​the master and driven gears to collect more accurate temperature data. The collected temperature information is fed back to the controller, which then controls the air cooler to maintain a temperature of T ± 5℃, where T is the optimal temperature for measuring efficiency. A vibration sensor is used to collect vibration data from the drive axle housing in real time to determine if the equipment is vibrating abnormally. If the vibration exceeds a set value, the equipment stops operating.

[0067] In one possible implementation, the step of performing feature processing on multiple real-time vehicle data information under different regional operating conditions to determine vehicle characteristic information under different regional operating conditions includes:

[0068] Multiple real-time vehicle data information under different regional operating conditions are input into a pre-trained neural network model, and features are extracted from the multiple real-time vehicle data information under different regional operating conditions to determine the vehicle feature information under different regional operating conditions.

[0069] Here, multiple real-time vehicle data information under different regional operating conditions are input into a pre-trained neural network model. Feature extraction is performed on the multiple real-time vehicle data information under different regional operating conditions to determine the vehicle characteristic information under different regional operating conditions. This allows us to understand the user's driving habits and provides a guarantee for subsequent measurement of the vehicle assembly efficiency.

[0070] S102: For each of the aforementioned regional operating conditions, multiple input torque characteristic information and multiple input speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the input power of the driving vehicle under the regional operating conditions.

[0071] In this step, for each regional operating condition, multiple input torque characteristic information and multiple input speed characteristic information in the vehicle characteristic information under the regional operating condition are measured in segments to determine the input power of the vehicle under the regional operating condition.

[0072] In this segmented measurement, the corresponding torque sensor is determined based on the torque characteristic information, and the corresponding speed sensor is determined based on the speed characteristic information. For example, the third torque sensor N1 is a small-range sensor used to collect torque information of (0~n1) Nm, the second torque sensor N2 is a medium-range sensor used to collect torque information of (n1~n2) Nm, the first torque sensor N3 is a large-range sensor used to collect torque information of (n2~∞) Nm, the first speed sensor V1 is a small-range sensor used to collect speed information of (0~v1) r / min, and the second speed sensor V2 is a large-range sensor used to collect speed information of (v1~∞) r / min.

[0073] In one possible implementation, for each of the aforementioned regional operating conditions, multiple input torque characteristic information and multiple input speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the input power of the driving vehicle under the regional operating conditions, including:

[0074] a: For each input torque feature information, detect whether the input torque feature information is less than the first torque information. If it is greater than the first torque information, then detect whether the input torque feature information is less than the second torque information. If it is greater than the second torque information, then determine the target input torque feature information under the working conditions of this region based on the first torque sensor; wherein, the first torque information is less than the second torque information.

[0075] Here, for each input torque characteristic information, it is detected whether the input torque characteristic information is less than the first torque information. If it is greater than the first torque information, it is detected whether the input torque characteristic information is less than the second torque information. If it is greater than the second torque information, the target input torque characteristic information under the working conditions of this region is determined based on the first torque sensor.

[0076] The first torque information is less than the second torque information. The first torque information and the second torque information are determined based on the torque requirements of the assembly and the sensor capabilities. For example, the first torque information (n1) = 100 and the first torque information (n2) = 500.

[0077] Since all torque characteristic information is directly measured by a large-range torque sensor, the torque characteristic information may not be very accurate. Therefore, it is necessary to determine the corresponding torque sensor based on the torque characteristic information, the first torque information, and the second torque information, and then use the determined torque sensor to re-determine the target input torque characteristic information under the local operating conditions.

[0078] In one possible implementation, for each input torque characteristic information, it is detected whether the input torque characteristic information is less than a first torque information; if it is greater than the first torque information, it is detected whether the input torque characteristic information is less than a second torque information; if it is greater than the second torque information, the target input torque characteristic information under the operating conditions of the region is determined based on the first torque sensor, further comprising:

[0079] (1): If the input torque characteristic information is less than the first torque information, the target input torque characteristic information under the working conditions of the region is determined according to the second torque sensor.

[0080] Here, if the input torque characteristic information is less than the first torque information, the target input torque characteristic information under the working conditions of this region is determined based on the second torque sensor.

[0081] (2): If the input torque characteristic information is less than the second torque information, the target input torque characteristic information under the working conditions of this region is determined according to the third torque sensor; wherein, the torque measurement range of the first torque sensor, the second torque sensor and the third torque sensor decreases in sequence.

[0082] Here, if the input torque characteristic information is less than the second torque information, the target input torque characteristic information under the working conditions of this region is determined based on the third torque sensor.

[0083] The torque measurement ranges of the first torque sensor, the second torque sensor, and the third torque sensor decrease sequentially.

[0084] b: For each input speed characteristic information, detect whether the input speed characteristic information is less than the first speed information. If so, determine the target input speed characteristic information under the operating conditions of this region based on the first speed sensor. If not, determine the target input speed characteristic information under the operating conditions of this region based on the second speed sensor.

[0085] Here, for each input speed characteristic information, it is detected whether the input speed characteristic information is less than the first speed information. If so, the target input speed characteristic information under the working conditions of this region is determined according to the first speed sensor. If not, the target input speed characteristic information under the working conditions of this region is determined according to the second speed sensor.

[0086] Here, the first speed information is determined based on the speed requirements of the assembly and the sensor capability, and can be 100 r / min.

[0087] The speed measurement range of the first speed sensor is smaller than that of the second speed sensor.

[0088] c: Based on the target input torque characteristic information and the target input speed characteristic information under the operating conditions of this region, the input power of the driving vehicle under the operating conditions of this region is determined.

[0089] Here, the input power of the vehicle under the operating conditions of this region is determined based on the target input torque characteristic information and the target input speed characteristic information.

[0090] Here, the process of determining the input power of the vehicle under the operating conditions of this region based on the target input torque characteristic information and the target input speed characteristic information can be achieved by existing technical means, so this part will not be elaborated here.

[0091] S103: For each of the aforementioned regional operating conditions, multiple output torque characteristic information and multiple output speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the output power of the driving vehicle under the regional operating conditions.

[0092] In this step, for each regional operating condition, multiple output torque characteristic information and multiple output speed characteristic information in the vehicle characteristic information under the regional operating condition are measured in segments to determine the output power of the driving vehicle under the regional operating condition.

[0093] In one possible implementation, for each of the aforementioned regional operating conditions, multiple output torque characteristic information and multiple output speed characteristic information in the vehicle characteristic information under the regional operating conditions are measured in segments to determine the output power of the driving vehicle under the regional operating conditions, including:

[0094] i: For each output torque characteristic information N, detect whether the output torque characteristic information is less than the third torque information n3. If it is greater than the third torque information n3, then detect whether the input torque characteristic information is less than the fourth torque information n4. If it is greater than the fourth torque information n4, then determine the target input torque characteristic information N_out under the operating conditions of this region based on the fourth torque sensor N4; wherein, the third torque information is less than the fourth torque information. If the output torque characteristic information N is less than the third torque information n3, then determine the target output torque characteristic information N_out under the operating conditions of this region based on the fifth torque sensor N5. If the output torque characteristic information N is less than the fourth torque information n4, then determine the target output torque characteristic information under the operating conditions of this region based on the sixth torque sensor N6; wherein, the torque measurement range of the fourth torque sensor N4, the fifth torque sensor N5, and the sixth torque sensor N6 decreases sequentially.

[0095] ii: For each of the output speed characteristic information V, detect whether the output speed characteristic information V is less than the second speed information v2. If so, determine the target output speed characteristic information V_out under the operating conditions of this region based on the third speed sensor V3. If not, determine the target output speed characteristic information V_out under the operating conditions of this region based on the fourth speed sensor V4.

[0096] iii: Based on the target output torque characteristic information N_out and the target output speed characteristic information V_out under the operating conditions of this region, the output power P_out of the driving vehicle under the operating conditions of this region is determined.

[0097] The process for determining the output power of a vehicle under local operating conditions is the same as the process for determining the output power of a vehicle, and will not be repeated here.

[0098] For further details, please refer to Figure 2 , Figure 2 This is a schematic diagram of the drive axle of a driving vehicle provided in an embodiment of this application. Figure 2 As shown, the structure includes a drive axle housing, a controller, multiple torque sensors, multiple speed sensors, a temperature sensor, and a vibration sensor. The first, second, and third torque sensors, the first and second speed sensors are installed at the input end of the drive axle housing, while the fourth, fifth, and sixth torque sensors, the third and fourth speed sensors are installed at the output end of the drive axle housing. The controller collects and controls the data from these multiple sensors.

[0099] S104: Based on the input power and output power of the driving vehicle under each of the regional operating conditions, determine the overall efficiency of the driving vehicle under multiple regional operating conditions.

[0100] In this step, the overall efficiency of the vehicle under multiple regional operating conditions is determined based on the input power and output power of the vehicle under each regional operating condition.

[0101] The overall efficiency rate is the efficiency of driving vehicles under all regional operating conditions.

[0102] In one possible implementation, determining the vehicle's overall efficiency under multiple regional operating conditions based on the vehicle's input and output power for each of the regional operating conditions includes:

[0103] I: The input power of the driving vehicle under each of the aforementioned regional operating conditions is accumulated and summed to determine the target input power.

[0104] Here, the input power of the driving vehicle under each regional operating condition is accumulated and summed to determine the target input power.

[0105] II: The output power of the driving vehicles under each of the aforementioned regional operating conditions is accumulated and summed to determine the target output power.

[0106] Here, the output power of the driving vehicle under each regional operating condition is accumulated and summed to determine the target output power.

[0107] III: Determine the efficiency for each region's operating conditions based on the target input power and the target output power for each region's operating conditions.

[0108] Here, the efficiency under each regional operating condition is determined by dividing the target output power of each region by the corresponding target input power.

[0109] IV: The efficiency under multiple regional operating conditions is accumulated and summed to determine the overall efficiency of the driving vehicle under the multiple regional operating conditions.

[0110] Here, the efficiency under multiple regional operating conditions is accumulated and summed to determine the overall efficiency of the vehicle under multiple regional operating conditions.

[0111] In one possible implementation, after determining the vehicle assembly efficiency under multiple regional operating conditions based on the input and output power of the vehicle for each of the regional operating conditions, the vehicle assembly efficiency determination method further includes:

[0112] The target optimization strategy for the vehicle corresponding to the overall efficiency of the vehicle is selected from a set of preset vehicle optimization strategies.

[0113] Here, the corresponding driving vehicle target optimization strategy is selected from a number of preset driving vehicle optimization strategies based on the overall efficiency of the driving vehicle.

[0114] Among these, vehicle driving optimization strategies can be as follows: If the user frequently drives in suburban or highway areas, resulting in a higher proportion of high-speed driving conditions, high-efficiency ball bearings can be used to reduce bearing friction losses, low-viscosity lubricating oil can be used to reduce oil churning losses, small-ratio gears and small offset distances can be used to reduce meshing friction losses, and low oil levels or active lubrication can be used to reduce oil churning losses. If the user frequently drives in mountainous areas, resulting in a higher proportion of high torque, the vehicle should be equipped with tapered bearings with greater load-bearing capacity, or a combination of tapered bearings and ball bearings, which increases the viscosity of the lubricating oil.

[0115] For further details, please refer to Figure 3 This is a schematic diagram illustrating a method for determining the efficiency of a user's driving vehicle assembly, provided in an embodiment of this application. Figure 3As shown, the system detects whether the vibration data of the drive axle housing of the vehicle exceeds the preset vibration value during driving. If so, the measurement ends. If so, the system detects whether the temperature of the lubricating oil in the gear contact area of ​​the drive axle housing of the vehicle is within the preset temperature range during driving. If not, the temperature of the lubricating oil in the gear contact area is readjusted. If so, the system performs feature processing on multiple real-time vehicle data under different regional operating conditions to determine the vehicle characteristic information under different regional operating conditions. The system detects whether the input torque characteristic information N of each region's operating condition is less than the first torque information n1. If so, the second torque sensor N2 determines the target input torque characteristic information N_in. Otherwise, it detects whether N is less than the second torque information n2. If so, the third torque sensor N3 determines the target input torque characteristic information N_in.
