Description

Technical Field

[0001] This application relates to the field of diesel vehicle testing technology, and in particular to an evaluation method and apparatus for assessing the adaptability of diesel vehicles to road conditions based on carbon load balance. Background Technology

[0002] The particulate filter in a diesel vehicle is used to treat particulate matter in the diesel exhaust. As the mileage of a diesel vehicle increases, the carbon load in the particulate filter will continuously increase, which will affect engine power. Therefore, when the maximum permissible carbon load set for the diesel vehicle is exceeded, the particulate filter will be regenerated.

[0003] Diesel vehicles are designed for different road conditions. Before being put into use, a particulate filter carbon balance test must be conducted to determine whether the diesel vehicle is suitable for the corresponding road conditions. A diesel vehicle not matched to the corresponding road conditions will cause frequent particulate filter regeneration, resulting in fuel waste. Traditional technologies cannot assess the particulate filter carbon balance of diesel vehicles under different road conditions. Summary of the Invention

[0004] Therefore, it is necessary to provide a method and apparatus for evaluating the carbon load balance of diesel vehicles under different road conditions, which can assess the carbon load balance of particulate filters under different road conditions.

[0005] Firstly, this application provides a method for evaluating the road condition suitability of diesel vehicles based on carbon load balance. The method includes:

[0006] Determine the current test road conditions for the target diesel vehicle, and determine the target cyclic test conditions based on the current test road conditions;

[0007] Control the target diesel vehicle to regenerate the particulate filter, and when the temperature of the particulate filter in the target diesel vehicle reaches a preset temperature threshold, obtain the initial weight of the particulate filter.

[0008] Under the target cycle test conditions, a particulate filter carbon load balance test is conducted on the target diesel vehicle. The real-time weight of the particulate filter is obtained at preset time intervals, and the real-time weight gain is obtained by subtracting the initial weight from the real-time weight.

[0009] During the carbon load balance test of the particulate filter, if the real-time weight gain stops increasing before reaching the preset carbon load limit, it is determined that the target diesel vehicle has achieved carbon load balance of the particulate filter under the current test road conditions, and it is determined that the target diesel vehicle is suitable for the current test road conditions.

[0010] In one embodiment, the method further includes:

[0011] During the carbon load balance test of the particulate filter, if the real-time weight gain reaches the preset carbon load limit, the operating parameters of the particulate filter are adjusted, and the process returns to the step of controlling the target diesel vehicle to regenerate the particulate filter and continues.

[0012] In one embodiment, adjusting the operating parameters of the particle trap includes:

[0013] At least one of the temperature of the particulate trap or the gas concentration in the particulate trap is adjusted.

[0014] In one embodiment, the current test road condition is an urban driving condition, a suburban driving condition, or a highway driving condition; determining the target cyclic test conditions based on the current test road condition includes:

[0015] Given that the current test road condition is urban driving condition, the first 600 seconds of the WHTC cycle test conditions will be used as the target cycle test conditions.

[0016] Given that the current test road condition is a suburban working condition, the intermediate 600-second cycle test condition in the WHTC cycle process will be used as the target cycle test condition.

[0017] Given that the current test road condition is a high-speed condition, the last 600 seconds of the WHTC cycle test condition is taken as the target cycle test condition.

[0018] In one embodiment, the test road conditions are divided into multiple types, and there is a test sequence among the multiple test road conditions; the method further includes:

[0019] After determining that the target diesel vehicle is suitable for the current test road conditions, the current test road conditions are changed according to the test sequence, and the process returns to the step of determining the target cyclic test conditions based on the current test road conditions and continues to execute. The above process is repeated until all test road conditions have been tested.

[0020] In one embodiment, the target diesel vehicle is any one of the following categories of diesel vehicles equipped with a diesel engine: M2, M3, N1, N2, N3, or M1 category diesel vehicles with a total mass greater than 3500KG.

[0021] Secondly, this application also provides an evaluation device for diesel vehicle road condition adaptability based on carbon load balance. The device includes:

[0022] The test condition determination module is used to determine the current test road conditions of the target diesel vehicle and determine the target cyclic test conditions based on the current test road conditions.

[0023] The starting weight acquisition module is used to control the target diesel vehicle to regenerate the particulate filter and acquire the starting weight of the particulate filter when the temperature of the particulate filter in the target diesel vehicle reaches a preset temperature threshold.

[0024] The weight gain acquisition module is used to conduct a particulate filter carbon load balance test on the target diesel vehicle under the target cycle test conditions, acquire the real-time weight of the particulate filter at preset time intervals, and subtract the initial weight from the real-time weight to obtain the real-time weight gain.

[0025] The adaptation module is used to determine that the target diesel vehicle has achieved carbon load balance of the particulate filter under the current test road conditions if the real-time weight gain no longer increases before reaching the preset carbon load limit during the carbon load balance test of the particulate filter, and to determine that the target diesel vehicle is adapted to the current test road conditions.

[0026] Thirdly, this application also provides a computer device. The computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the steps of the methods in any of the above embodiments.

[0027] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, implements the steps of the methods in any of the above embodiments.

[0028] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, implements the steps of the methods in any of the above embodiments.

[0029] The aforementioned evaluation method and apparatus for assessing diesel vehicle suitability for road conditions based on carbon load balance determines the current test road conditions of the target diesel vehicle and, based on the current test road conditions, determines the target cyclic test conditions. Under the target cyclic test conditions, a particulate filter carbon load balance test is conducted on the target diesel vehicle. The real-time weight of the particulate filter is acquired at preset time intervals. The real-time weight gain is obtained by subtracting the initial weight of the particulate filter acquired under certain conditions from the real-time weight gain. During the particulate filter carbon load balance test, if the real-time weight gain stops increasing before reaching the preset carbon load upper limit, it is determined that the target diesel vehicle has achieved particulate filter carbon load balance under the current test road conditions, and the target diesel vehicle is deemed suitable for the current test road conditions. Compared to traditional technologies that cannot evaluate the carbon load balance of particulate filters for diesel vehicles under different road conditions, this application first determines the current test road conditions that match the target diesel vehicle, and then determines the target cycle test conditions based on the current test road conditions. This ensures that the carbon load balance test of the particulate filter is carried out on the target diesel vehicle under the target cycle test conditions, and obtains the compatibility between the target diesel vehicle and the current test road conditions. This allows for the evaluation of the carbon load balance of the particulate filter for diesel vehicles under different test road conditions. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] In this embodiment, a method for evaluating the adaptability of diesel vehicles to road conditions based on carbon load balance is provided. This embodiment uses the application of this method to computer equipment as an example for illustration. It can be understood that this method can also be applied to servers, and can also be applied to systems including computer equipment and servers, and can be implemented through the interaction between computer equipment and servers.

[0036] Figure 1 This is a flowchart illustrating the diesel vehicle road condition adaptation evaluation method based on carbon load balance provided in the embodiments of this application. The method is applied in computer equipment or a server. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0037] S101, determine the current test road conditions of the target diesel vehicle, and determine the target cycle test conditions based on the current test road conditions.

[0038] The current test road conditions represent the actual road conditions that the target diesel vehicle would encounter in real life, and can be set manually. The target cycle test conditions are cycle test conditions with certain set standards corresponding to the current test road conditions, and can be set manually, usually according to nationally unified standards.

[0039] S102, control the target diesel vehicle to regenerate the particulate filter, and obtain the initial weight of the particulate filter when the temperature of the particulate filter in the target diesel vehicle reaches the preset temperature threshold.

[0040] Particulate filter regeneration refers to the secondary combustion of carbon particles collected in the particulate filter. The preset temperature threshold is manually set, for example, it can be set to 180 degrees Celsius. The starting weight is the weight measured after particulate filter regeneration, assuming the particulate filter temperature in the target diesel vehicle reaches the preset temperature threshold.

[0041] S103, under the target cycle test conditions, a carbon load balance test of the particulate filter is carried out on the target diesel vehicle. The real-time weight of the particulate filter is obtained at preset time intervals, and the real-time weight gain is obtained by subtracting the initial weight from the real-time weight.

[0042] The preset duration is set manually and is not limited in specific terms; for example, the preset duration can be set to 5 hours.

[0043] S104. During the carbon load balance test of the particulate filter, if the real-time weight gain stops increasing before reaching the preset carbon load limit, it is determined that the target diesel vehicle has achieved carbon load balance of the particulate filter under the current test road conditions, and the target diesel vehicle is suitable for the current test road conditions.

[0044] The preset carbon load limit is set manually.

[0045] The diesel vehicle adaptability assessment method based on carbon load balance provided in this embodiment determines the current test road conditions of the target diesel vehicle and determines the target cyclic test conditions based on the current test road conditions. Under the target cyclic test conditions, a particulate filter carbon load balance test is conducted on the target diesel vehicle. The real-time weight of the particulate filter is obtained at preset time intervals. The real-time weight gain is obtained by subtracting the initial weight of the particulate filter obtained under certain conditions from the real-time weight gain. If the real-time weight gain stops increasing before reaching the preset carbon load limit during the particulate filter carbon load balance test, it is determined that the target diesel vehicle has achieved particulate filter carbon load balance under the current test road conditions, and the target diesel vehicle is adapted to the current test road conditions. Compared to traditional technologies that cannot evaluate the carbon load balance of particulate filters for diesel vehicles under different road conditions, this embodiment first determines the current test road conditions that match the target diesel vehicle, and then determines the target cycle test conditions based on the current test road conditions. This ensures that the carbon load balance test of the particulate filter is carried out on the target diesel vehicle under the target cycle test conditions, and obtains the compatibility between the target diesel vehicle and the current test road conditions. This allows for the evaluation of the carbon load balance of the particulate filter for diesel vehicles under different test road conditions.

[0046] In one embodiment, the method further includes:

[0047] If the real-time weight gain reaches the preset carbon load limit during the carbon load balance test of the particulate filter, the operating parameters of the particulate filter will be adjusted, and the process will return to the step of regenerating the particulate filter in the target diesel vehicle and continue.

[0048] In this embodiment, if the real-time weight gain reaches the preset carbon load limit, it indicates that the target diesel vehicle has not achieved carbon load balance of the particulate filter under the current test road conditions. At this time, by adjusting the usage parameters of the particulate filter, the target diesel vehicle can achieve carbon load balance of the particulate filter under the current test road conditions. This ensures that the target diesel vehicle is adapted to the current test road conditions, rather than directly replacing the engine of the target diesel vehicle. This improves the utilization rate of the engine of the target diesel vehicle and improves the overall performance of the target diesel vehicle.

[0049] In one embodiment, adjusting the operating parameters of the particulate trap includes:

[0050] Adjust at least one of the particulate filter temperature or the gas concentration in the particulate filter.

[0051] The gas concentration in the particulate filter is the nitrogen oxide gas concentration, which includes both nitric oxide and nitrogen dioxide. In some embodiments, the temperature of the particulate filter is adjusted by increasing the temperature of the particulate filter; the gas concentration in the particulate filter is adjusted by increasing the proportion of nitrogen dioxide in the nitrogen oxide gas.

[0052] In this embodiment, the temperature of the particulate filter and the gas concentration in the particulate filter affect the regeneration of the particulate filter. Adjusting at least one of the particulate filter temperature or the gas concentration in the particulate filter can improve the performance of the adjusted particulate filter, thereby further ensuring that the target diesel vehicle can adapt to the current test road conditions.

[0053] In one embodiment, the current test road condition is an urban test, a suburban test, or a highway test; the target cyclic test conditions are determined based on the current test road condition, including:

[0054] Under the current test road conditions of urban conditions, the test conditions of the first 600 seconds of the WHTC cycle will be used as the target cycle test conditions.

[0055] Given that the current test road conditions are suburban conditions, the intermediate 600-second cycle test conditions in the WHTC cycle process will be used as the target cycle test conditions.

[0056] Under the current test road conditions of high speed, the test conditions of the last 600 seconds of the WHTC cycle are used as the target cycle test conditions.

[0057] The WHTC cycle is the engine emission test cycle proposed in the European Stage 6 emission standards.

[0058] In this embodiment, the target cycle test conditions are determined based on the current test road conditions, and the cycle test conditions in the WHTC cycle process are determined as the target cycle test conditions. This ensures the accuracy of the target cycle test conditions and avoids the target diesel vehicle being unable to adapt to the current test road conditions in actual use due to inaccurate target cycle test conditions.

[0059] In one embodiment, the test road conditions are divided into multiple types, and there is a test sequence among the multiple test road conditions; the method further includes:

[0060] After determining that the target diesel vehicle is suitable for the current test road conditions, change the current test road conditions according to the test sequence, and return to the step of determining the target cyclic test conditions based on the current test road conditions and continue to execute. Repeat the above process until all test road conditions have been tested.

[0061] The test road conditions include urban driving conditions, suburban driving conditions, highway driving conditions, urban fully loaded driving conditions, suburban fully loaded driving conditions, highway fully loaded driving conditions, urban empty driving conditions, suburban empty driving conditions, highway empty driving conditions, and port cycle driving conditions, without specific limitations. Corresponding test road conditions are set for different target diesel vehicles. For example, the test road conditions for mail trucks are set as suburban driving conditions and highway driving conditions.

[0062] In this embodiment, when the target diesel vehicle is subjected to multiple test road conditions, the target diesel vehicle can achieve carbon load balance of the particulate filter under each test road condition, ensuring that the target diesel vehicle is suitable for all test road conditions.

[0063] In one embodiment, the target diesel vehicle is any one of the following categories of diesel vehicles equipped with a diesel engine: M2, M3, N1, N2, N3, or M1 category diesel vehicles with a gross vehicle weight greater than 3500KG.

[0064] The categories are as follows: M1: Passenger vehicles with no more than 9 seats, including the driver's seat; M2: Passenger vehicles with no more than 9 seats, including the driver's seat, and a maximum design gross vehicle weight of no more than 5,000 kg; M3: Passenger vehicles with no more than 9 seats, including the driver's seat, and a maximum design gross vehicle weight of more than 5,000 kg; N1: Freight vehicles with a maximum design gross vehicle weight of no more than 3,500 kg; N2: Freight vehicles with a maximum design gross vehicle weight of more than 3,500 kg but not exceeding 12,000 kg; N3: Freight vehicles with a maximum design gross vehicle weight of more than 12,000 kg.

[0065] In this embodiment, the target diesel vehicle is set as a heavy-duty diesel vehicle. This mismatch is more obvious in heavy-duty diesel vehicles, and the existing technology cannot evaluate the carbon load balance of the particulate filter of heavy-duty diesel vehicles under different test road conditions. Setting it as a heavy-duty diesel vehicle allows for more targeted testing and improves resource utilization.

[0066] Here, the method for evaluating the road condition suitability of diesel vehicles based on carbon load balance is described in detail. Taking a heavy-duty diesel mail truck as an example, a flowchart illustrating the road condition suitability evaluation process for a heavy-duty diesel mail truck in one embodiment is shown below. Figure 2 As shown, it includes the following:

[0067] S201, determine the test road conditions for heavy-duty diesel mail trucks and determine the test sequence for the test road conditions.

[0068] The test road conditions included suburban and expressway conditions. The test sequence was to conduct the suburban condition test first, followed by the expressway condition test.

[0069] S202, Determine the target cyclic test conditions based on suburban working conditions.

[0070] The target cycle test conditions are the intermediate 600-second cycle test conditions in the WHTC cycle process.

[0071] S203, control the heavy-duty diesel mail truck to regenerate the particulate filter. When the temperature of the particulate filter in the heavy-duty diesel mail truck reaches the preset temperature threshold, obtain the initial weight of the particulate filter. Under the intermediate 600-second cycle test conditions in the WHTC cycle process, conduct a carbon load balance test on the heavy-duty diesel mail truck particulate filter. Obtain the real-time weight of the particulate filter at preset intervals, and subtract the initial weight from the real-time weight to obtain the real-time weight gain.

[0072] S204. Determine whether the heavy-duty diesel mail truck is suitable for suburban working conditions based on the real-time weight gain. If it is suitable, proceed to step S206; if it is not suitable, proceed to step S205.

[0073] S205, adjust the operating parameters of the particle trap and return to step S203 to continue execution.

[0074] S206, change the suburban operating condition to the high-speed operating condition, and determine the target cycle test conditions based on the high-speed operating condition.

[0075] The target cycle test conditions are the last 600 seconds of the WHTC cycle test conditions.

[0076] S207 controls the heavy-duty diesel mail truck to regenerate the particulate filter. When the temperature of the particulate filter in the heavy-duty diesel mail truck reaches the preset temperature threshold, the initial weight of the particulate filter is obtained. Under the test conditions of the last 600 seconds of the WHTC cycle, the carbon load balance test of the particulate filter is carried out on the heavy-duty diesel mail truck. The real-time weight of the particulate filter is obtained at preset intervals, and the real-time weight gain is obtained by subtracting the initial weight from the real-time weight.

[0077] S208: Determine whether the heavy-duty diesel mail truck is suitable for high-speed operation based on the real-time weight gain. If not, adjust the operating parameters of the particulate filter and return to step S207 to continue execution.

[0078] The method for assessing the adaptability of diesel vehicles to road conditions based on carbon load balance provided in this embodiment can assess the carbon load balance of diesel vehicles, shift the risk forward, optimize the carbon load level of diesel engines, effectively identify risks, improve engine adaptability, and effectively shorten the engine development cycle.

[0079] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0080] Based on the same inventive concept, this application also provides a carbon load balance-based diesel vehicle road condition assessment device for implementing the aforementioned carbon load balance-based diesel vehicle road condition assessment method. The solution provided by this device is similar to the implementation described in the above method. Therefore, the specific limitations of one or more embodiments of the carbon load balance-based diesel vehicle road condition assessment device provided below can be found in the limitations of the carbon load balance-based diesel vehicle road condition assessment method described above, and will not be repeated here.

[0081] See Figure 3 , Figure 3 This is a structural block diagram of a diesel vehicle road condition adaptation evaluation device based on carbon load balance provided in this application embodiment. The device 300 includes: a test condition determination module 301, an initial weight acquisition module 302, a weight gain acquisition module 303, and an adaptation module 304, wherein:

[0082] The test condition determination module 301 is used to determine the current test road conditions of the target diesel vehicle and determine the target cyclic test conditions based on the current test road conditions.

[0083] The starting weight acquisition module 302 is used to control the target diesel vehicle to regenerate the particulate filter. When the temperature of the particulate filter in the target diesel vehicle reaches a preset temperature threshold, the starting weight of the particulate filter is acquired.

[0084] The weight gain acquisition module 303 is used to conduct a particulate filter carbon load balance test on a target diesel vehicle under target cycle test conditions. It acquires the real-time weight of the particulate filter at preset time intervals and subtracts the initial weight from the real-time weight to obtain the real-time weight gain.

[0085] The adapter module 304 is used to determine that the target diesel vehicle has achieved carbon load balance of the particulate filter under the current test road conditions if the real-time weight gain no longer increases before reaching the preset carbon load limit during the particulate filter carbon load balance test, and to determine that the target diesel vehicle is adapted to the current test road conditions.

[0086] The diesel vehicle road condition assessment device based on carbon load balance provided in this embodiment determines the current test road conditions of the target diesel vehicle and determines the target cyclic test conditions based on the current test road conditions. Under the target cyclic test conditions, a particulate filter carbon load balance test is performed on the target diesel vehicle. The real-time weight of the particulate filter is obtained at preset time intervals. The real-time weight gain is obtained by subtracting the initial weight of the particulate filter obtained under certain conditions from the real-time weight gain. If the real-time weight gain stops increasing before reaching the preset carbon load upper limit during the particulate filter carbon load balance test, it is determined that the target diesel vehicle has achieved particulate filter carbon load balance under the current test road conditions, and the target diesel vehicle is determined to be suitable for the current test road conditions. Compared to traditional technologies that cannot evaluate the carbon load balance of particulate filters for diesel vehicles under different road conditions, this embodiment first determines the current test road conditions that match the target diesel vehicle, and then determines the target cycle test conditions based on the current test road conditions. This ensures that the carbon load balance test of the particulate filter is carried out on the target diesel vehicle under the target cycle test conditions, and obtains the compatibility between the target diesel vehicle and the current test road conditions. This allows for the evaluation of the carbon load balance of the particulate filter for diesel vehicles under different test road conditions.

[0093] The suburban test condition unit is used to take the intermediate 600-second cycle test conditions in the WHTC cycle as the target cycle test conditions when the current test road condition is suburban.

[0094] The high-speed test unit is used to take the last 600 seconds of the WHTC cycle test conditions as the target cycle test conditions when the current test road condition is a high-speed test condition.

[0095] Optionally, the test road conditions are divided into multiple types, and there is a test sequence among the multiple test road conditions; the device 300 also includes:

[0096] The test completion module is used to change the current test road conditions according to the test sequence after determining that the target diesel vehicle is suitable for the current test road conditions, and return to the step of determining the target cyclic test conditions based on the current test road conditions and continue to execute, repeating the above process until all test road conditions have been tested.

[0097] Optionally, the target diesel vehicle can be any one of the following categories of diesel vehicles equipped with diesel engines: M2, M3, N1, N2, N3, or M1 with a gross vehicle weight greater than 3500KG.

[0098] The various modules in the aforementioned diesel vehicle road condition adaptation assessment device based on carbon load balance can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the corresponding operations of each module.

The memory stores a computer program, and the processor executes the computer program to implement the steps of the diesel vehicle road condition assessment method based on carbon load balance provided in the above embodiment:

[0102] Determine the current test road conditions for the target diesel vehicle, and determine the target cycle test conditions based on the current test road conditions;

[0103] Control the target diesel vehicle to regenerate the particulate filter, and obtain the initial weight of the particulate filter when the temperature of the particulate filter in the target diesel vehicle reaches a preset temperature threshold.

[0104] Under the target cycle test conditions, a carbon load balance test of the particulate filter was carried out on the target diesel vehicle. The real-time weight of the particulate filter was obtained at each preset time interval, and the real-time weight gain was obtained by subtracting the initial weight from the real-time weight.

[0105] During the carbon load balance test of the particulate filter, if the real-time weight gain stops increasing before reaching the preset carbon load limit, it is determined that the target diesel vehicle has achieved carbon load balance of the particulate filter under the current test road conditions, and the target diesel vehicle is deemed to be suitable for the current test road conditions.

[0108] In one embodiment, the processor, when executing a computer program, also performs the following steps:

[0109] Adjust at least one of the particulate filter temperature or the gas concentration in the particulate filter.

[0110] In one embodiment, the processor, when executing a computer program, also performs the following steps:

[0111] The current test road conditions are urban, suburban, or highway conditions; when the current test road conditions are urban conditions, the first 600 seconds of the WHTC cycle test conditions will be used as the target cycle test conditions.

[0112] Given that the current test road conditions are suburban conditions, the intermediate 600-second cycle test conditions in the WHTC cycle process will be used as the target cycle test conditions.

[0113] Under the current test road conditions of high speed, the test conditions of the last 600 seconds of the WHTC cycle are used as the target cycle test conditions.

After determining that the target diesel vehicle is suitable for the current test road conditions, the current test road conditions are changed according to the test sequence, and the process is repeated from the step of determining the target cyclic test conditions based on the current test road conditions to the next step. The above process is repeated until all test road conditions have been tested.

[0116] In one embodiment, the processor, when executing a computer program, also performs the following steps:
