[0034] Embodiment 1

[0035] Figure 1 A flowchart of an engine calibration method is provided for Embodiment 1 of the present invention. This embodiment is applicable to the virtual calibration of the engine. This method can be executed by an engine calibration device, which can be implemented in the form of hardware and / or software, and the engine calibration device can be configured in a computer. As Figure 1 shown, the method includes:

[0036] S110. Obtain the pre-established initial engine software functions and calculate the function calibration results corresponding to the respective initial engine software functions.

[0037] Among them, the engine refers to the device that provides power in an automobile. Engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids, etc. In this embodiment, a diesel engine is taken as an example for illustration. The initial engine software function refers to the software function in the existing Electronic Control Unit (ECU). The initial engine software function can be cylinder deactivation and Diesel Particle Filter (DPF) regeneration, etc. Cylinder deactivation means closing some cylinders under partial load. By cylinder deactivation, the load rate of the working cylinders can be increased, thereby achieving the purpose of fuel saving. DPF regeneration refers to the process of oxidizing the soot in the diesel particle filter. In this embodiment, only cylinder deactivation and DPF regeneration are taken as examples for illustration, and the software functions are not limited. The function calibration result refers to the calibration result corresponding to the initial engine software function, and the function calibration result includes the lowest cost of the corresponding initial engine software function. Pre-establishment refers to the process of summarizing the existing software functions.

[0038] Figure 2 The flowchart of an engine calibration method provided in Embodiment 1 of the present invention is as follows. Step S110 mainly includes the following steps S111 to step S113:

[0039] S111. Obtain the pre-established initial engine software functions.

[0040] S112. Calibrate the cost elements of each initial engine software function.

[0041] Among them, the cost elements include procurement cost, site cost, maintenance cost, material cost, labor cost, manufacturing cost, service cost, and test cost; calibration refers to virtual calibration, and virtual calibration means calibration on the platform according to the established software functions. The platform includes a Model in Loop (MIL) test platform and a Hardware in Loop (HIL) test platform. The procurement cost is divided according to the two platforms, and the procurement cost includes freight, installation fees, etc.; the site cost refers to the space cost required for virtual calibration, and the space required for different establishment methods of virtual calibration is also different; the maintenance cost refers to the regular maintenance required for virtual calibration, and the equipment and software need to be maintained and upgraded, and the relevant costs for repairing faults; the material cost refers to the material cost consumed by virtual calibration. For example, if real loads are used in virtual calibration, customized special load boxes, components, and wiring harnesses, etc. these consumable materials are required; the labor cost is due to the need for virtual calibration modeling engineers who understand electronic control knowledge, mathematical modeling, and simulation modeling. The required labor cost can be calculated according to the development stage and the maximum workload; the manufacturing cost refers to the cost of transforming and upgrading the virtual calibration platform; the service cost refers to the costs in aspects such as training and technical consultation, and the test cost refers to the costs generated by virtual calibration modeling for bench and vehicle tests, as well as occupying the bench, water, electricity, oil, gas, and bench engineers, etc. After obtaining the pre-established initial engine software functions, the cost elements for calibrating each initial engine software function can be targeted.

[0042] S113. Obtain cost data based on the cost elements, and calculate the function calibration result according to the cost data. Optionally, calculating the function calibration result according to the cost data includes: respectively calculating the Model in Loop test result and the Hardware in Loop test result of the cost data; taking the minimum value of the Model in Loop test result and the Hardware in Loop test result as the function calibration result.

[0043] Specifically, based on the calibrated cost elements, cost data related to the cost elements can be obtained. The purpose of obtaining the cost data is to ensure the data source and accuracy, and at the same time obtain the lowest cost data information. The following Table 1 shows an example of the cost data obtained for the software function of cylinder deactivation:

[0044] Table 1

[0045]

[0046] Among them, the procurement cost in the cost data of the HIL platform is hardware + software, and the cost data in the MIL platform is software; the site cost in the cost data of the HIL platform is 15 square meters of effective space, and there is no cost data in the MIL platform; the maintenance cost in the cost data of the HIL platform is the hardware maintenance cost, and the cost data in the MIL platform is the software upgrade cost; the material cost in the cost data of the HIL platform is the ECU, wiring harness and load box, and there is no cost data in the MIL platform; the labor cost in the cost data of the HIL platform is the development cycle of an average of 3 full-time engineers for 3 months, and the labor cost data in the MIL platform is half of that in the HIL platform; the manufacturing cost in the cost data of the HIL platform is that it needs to be transformed and upgraded, and the cost data in the MIL platform is that no transformation and upgrade is required; the test cost in the cost data of the HIL platform is the test bench and test bench engineer, and there is no cost data in the MIL platform.

[0047] Specifically, after obtaining the cost data, the controller can calculate the model-in-the-loop test results and hardware-in-the-loop test results of the cost data respectively. The calculation method is to select the corresponding cost data according to the formula preset by the user. The user refers to the staff or technicians who perform engine virtual calibration.

[0048] Exemplarily, the user can set the cost = basic modeling (this machine) + basic modeling (post-processing) + special function modeling + HIL system + open-loop debugging + closed-loop debugging + test bench debugging + MIL system + virtual calibration equipment cost + calibration. Among them, basic modeling (this machine) = test cost [test bench cost (rental, maintenance, water, electricity, oil, gas, etc.) + labor cost (DOE scheme design, 15 working days of a test engineer) + prototype and sample (prototype trial production cost, sensor installation, consumables)] + data analysis (data processing and analysis labor) + modeling (45 working days of a modeling engineer); basic modeling (post-processing) = test cost [test bench cost (rental, maintenance, water, electricity, oil, gas, etc.) + labor cost (DOE scheme design, 15 working days of a test engineer) + prototype and sample (prototype trial production cost, sensor installation, consumables) + small sample test cost (about 100,000)] + data analysis (data processing and analysis labor) + modeling (45 working days of a modeling engineer); special function modeling = test cost (DOE design, special test conditions, test labor according to specific conditions) + data analysis (data processing and analysis labor) + modeling (working hours of a modeling engineer according to specific conditions) HIL system = design cost (board card resource design) + installation cost (average 3 working days) + load box manufacturing (according to requirements) + wiring harness customization cost

[0049] Specifically, the controller calculates the model-in-the-loop test results and hardware-in-the-loop test results of the cost data respectively; and makes the cost lowest and the profit optimal through planning, that is, the function calibration result is calculated by using the following formula (1):

[0050]

[0051] Among them, profit represents the functional calibration result, ti represents the development cycle of each function, and ti should be greater than 0 and less than the maximum total development cycle. That is, the minimum profit value in the model-in-the-loop test result and the hardware-in-the-loop test result is used as the functional calibration result.

[0052] S120. Establish a functional calibration table for the engine according to the functional calibration result.

[0053] Specifically, after the controller determines the functional calibration results corresponding to each initial engine software function, a functional calibration table for the engine can be established. Among them, the functional calibration table includes the calibration results corresponding to each initial engine software. Further, through the functional calibration table, it can be further determined whether the corresponding software function exists and the corresponding calibration result. The following Table 2 shows the schematic of the functional calibration table:

[0054] Table 2

[0055] Software function Function calibration result Cylinder deactivation 10 (HIL) DPF regeneration 20 (MIL)

[0056] Among them, the functional calibration result corresponding to the software function of cylinder deactivation is 10, and the platform is HIL; the functional calibration result corresponding to DPF regeneration is 20, and the platform is MIL.

[0057] S130. Obtain each software function to be calibrated of the engine to be calibrated, and determine the final calibration result of the engine to be calibrated according to the functional calibration table and each software function to be calibrated.

[0058] Specifically, after the functional calibration table is established, the controller looks up the table for each software function to be calibrated of the engine to be calibrated obtained. When there is a matching software function in the functional calibration table, the calibration result corresponding to the software function in the functional calibration table can be output.

[0059] The technical solution of the embodiment of the present invention calculates the functional calibration result corresponding to the initial engine software function, and then establishes a functional calibration table for the engine according to the calculation result. Since the functional calibration table contains the functional calibration results corresponding to each initial engine software function, the final calibration result of the engine to be calibrated can be determined through the functional calibration table and each software function to be calibrated obtained, saving the workload of manual calibration and improving the calibration accuracy, thereby reducing the development cycle and development cost of the engine.

[0060] Embodiment 2

[0061] Figure 3This is a flow chart of an engine calibration method provided in the second embodiment of the present invention. This embodiment adds a process of determining the final calibration result of the engine to be calibrated based on the function calibration table and the functions of each software to be calibrated. The specific contents of steps S210-S220 are roughly the same as those of steps S110-S120 in the first embodiment, so they will not be described in detail in this embodiment. Figure 3 As shown, the method includes:

[0062] S210: Acquire pre-established initial engine software functions, and calculate function calibration results corresponding to each initial engine software function.

[0063] Optionally, the function calibration results corresponding to each initial engine software function are calculated, including: calibrating the cost elements of each initial engine software function, where the cost elements include procurement cost, site cost, maintenance cost, material cost, labor cost, manufacturing cost, service cost and testing cost; obtaining cost data based on the cost elements, and calculating the function calibration results according to the cost data.

[0064] Optionally, calculating the function calibration result based on the cost data includes: separately calculating the model-in-the-loop test result and the hardware-in-the-loop test result of the cost data; and taking the minimum value of the model-in-the-loop test result and the hardware-in-the-loop test result as the function calibration result.

[0065] S220: Create an engine function calibration table based on the calibration results.

[0066] S230: Obtain various software functions to be calibrated of the engine to be calibrated.

[0067] S240: Match each software function to be calibrated with the function calibration table to determine whether the software function to be calibrated is located in the function calibration table. If so, execute S250; otherwise, execute S260.

[0068] S250: Use the function calibration result matched in the function calibration table as the target calibration result.

[0069] Specifically, when the controller obtains the software functions to be calibrated of the engine to be calibrated, it will match each software function to be calibrated with the function calibration table, that is, it will determine whether the function calibration table contains the software function to be calibrated. If it does, the function calibration result corresponding to the software function in the function calibration table will be used as the target calibration result.

[0070] S260. Regulate each software function to be calibrated that has no matching results as an updated software function; calibrate cost elements for each updated software function, obtain cost data based on the cost elements, and calculate an updated calibration result based on the cost data; and use each updated calibration result as a target calibration result.

[0071] Specifically, when the function calibration table does not include the software function to be calibrated, the controller will regard each software function to be calibrated without a matching result as an updated software function, and recalibrate the cost elements of each updated software function. The cost elements include procurement cost, site cost, maintenance cost, material cost, labor cost, manufacturing cost, service cost, and test cost. Then, based on the cost elements, the corresponding cost data is obtained, and the model-in-the-loop test results and hardware-in-the-loop test results of the cost data are calculated respectively. The minimum value of the model-in-the-loop test results and the hardware-in-the-loop test results is used as the updated calibration result, and the calculated updated calibration result is used as the target calibration result.

[0072] Optionally, after calculating the updated calibration result according to the cost data, it includes: adding the updated calibration result and the corresponding updated software function to the function calibration table.

[0073] Specifically, when the updated calibration result is determined, the controller can add the updated calibration result and the corresponding updated software function to the function calibration table to update the function calibration table. It should be noted that when the cost data changes, the function calibration table will also be updated to ensure the accuracy of the function calibration table.

[0074] S270. Generate the final calibration result according to each target calibration result.

[0075] Optionally, generating the final calibration result according to each target calibration result includes: obtaining the weight value corresponding to each target calibration result; multiplying each target calibration result by the corresponding weight value and adding the products in sequence to generate the final calibration result.

[0076] Specifically, the weight value is input by the R & D personnel according to the importance of each target calibration result in the controller. The controller will multiply each target calibration result by the corresponding weight value and then add the products to obtain the final calibration result. For example, if the weight value corresponding to target calibration result 1 is 0.4 and the weight value corresponding to target calibration result 2 is 0.6, then the final calibration result = 0.4 * target calibration result 1 + 0.6 * target calibration result 2.

[0077] In the technical solution of the embodiment of the present invention, by calculating the function calibration result corresponding to the initial engine software function, and then establishing a function calibration table for the engine according to the calculation result. Since the function calibration table contains the function calibration results corresponding to each initial engine software function, the final calibration result of the engine to be calibrated can be determined through the function calibration table and each software function to be calibrated obtained, saving the workload of manual calibration while improving the calibration accuracy, thereby reducing the development cycle and development cost of the engine. And when there is no matching result in the function calibration table, the calculated updated software function and the corresponding updated calibration result can be added to the function calibration table to realize the update of the function calibration table, so as to facilitate better calibration in the future.
