The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art can understand,Figure 1 The structure shown does not constitute a limitation on the shift point determination device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0057] As Figure 1 shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a shift point determination program.

[0058] In Figure 1 the shift point determination device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the shift point determination device of the present invention may be provided in the shift point determination device. The shift point determination device calls the shift point determination program stored in the memory 1005 through the processor 1001 and executes the shift point determination method provided by the embodiments of the present invention.

[0059] The embodiments of the present invention provide a shift point determination method. Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of the shift point determination method of the present invention.

[0060] In this embodiment, the shift point determination method includes the following steps:

[0061] Step S10: Generate an initial shift line according to the user's shift line generation instruction.

[0062] It should be noted that the execution subject of the embodiments of the present invention is a platform for selecting and determining shift points, such as the MATLAB software platform, or other shift point determination platforms that can achieve the same or similar functions. This embodiment does not limit this, and this embodiment is described by taking the MATLAB software platform as an example. MATLAB is a commercial mathematical software produced by MathWorks, Inc. in the United States, mainly used for algorithm development, data visualization, data analysis, and numerical calculation, etc., and is widely used in many fields such as scientific research and engineering calculation.

[0063] The user's shift line generation instruction refers to that the user needs to upload the shift line file to be generated on the MATLAB software. After the background receives the shift line file uploaded by the user, it identifies the shift line file and generates an initial shift line.

[0064] Step S20: Obtain the test field rules in the test field data.

[0065] In this embodiment, the test site data is the site where vehicle emission comprehensive fuel consumption tests need to be carried out. Different test sites have different test site rules during tests. Therefore, the test site rules corresponding to different test site data can be obtained.

[0066] Specifically, obtaining the test site rules in the test site data may include: obtaining the user's test request; parsing the test request to obtain the corresponding test site data; obtaining the test site rules in the test site data.

[0067] It should be understood that when the user needs to conduct vehicle emission comprehensive fuel consumption tests, the user can click "Select Test Site" on the main tool interface of the MATLAB software and select the corresponding test site data in the test site selection interface directory that pops up to generate a test request. When the MATLAB software platform detects the user's test request, it parses the test request to obtain the corresponding test site data. For example, when the user selects Test Site A in the MATLAB software, a test request is generated, and the background parses the user's test request to obtain the content of Test Site A and extracts the corresponding test site rules from Test Site A. The test site rules may include the map information, test information, shift position information, etc. of Test Site A.

[0068] Step S30: Screen the initial shift line based on the test site rules to obtain shift points.

[0069] The positions of the shift points corresponding to different test site rules are also different. Therefore, after obtaining the test site rules, the initial shift line can be screened and marked based on the test site rules, and shift points can be marked on the shift line to obtain the marked shift points. The shift line can be quickly generated by the MATLAB software, and the shift points and the corresponding shift times can be quickly and accurately selected and determined according to the test site rules, facilitating subsequent tests based on the shift points.

[0070] In this embodiment, by generating an initial shift line according to the user's shift line generation instruction, obtaining the test site rules in the test site data, and screening the initial shift line based on the test site rules to obtain shift points, the shift points in the initial shift line can be quickly screened and determined, improving the efficiency of shift point determination and reducing time and labor costs.

[0071] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of the method for determining shift points of the present invention.

[0072] Based on the above first embodiment, step S10 of the method for determining shift points in this embodiment specifically includes:

[0073] Step S101: Parse the user's shift line generation instruction to obtain the import path.

[0074] It should be understood that the shift cable generation instruction is the instruction information generated after the user clicks the import shift cable button in the MATLAB software. When the user clicks the import shift cable button, a shift cable generation instruction is generated, and the background server parses the shift cable generation instruction and pops up the import path of the shift cable.

[0075] The import path is the original path where the shift cable data file is stored. For example, if the shift cable data file is stored in the documents on drive E of the computer, then the import path of the shift cable is the documents on drive E of the computer.

[0076] Step S102: Select the shift cable through the import path.

[0077] In a specific implementation, after obtaining the import path of the shift cable data file, all the shift cable data files stored in the import path can be obtained. For example, if the import path is the documents on drive E of the computer, then the documents on drive E of the computer can be opened and browsed through the import shift cable button in the MATLAB software, and the shift cables in the documents can be selected to determine the shift cables that the user needs to select, and the selection result is obtained.

[0078] Step S103: Select the software for generating the shift cable according to the selection result.

[0079] It should be understood that after the user selects the corresponding shift cable, the corresponding software for generating the shift cable can be selected in the generation shift cable tool column of the MATLAB software. The software for generating the shift cable includes: ACCESS software, AVL_CRUSE software, and AVL_DRIVE software, etc., and it can also be other software that can generate shift cables. This embodiment does not limit this. The MATLAB software can update the software for generating the shift cable in real time according to the user's needs. When the user does not find the required software for generating the shift cable on the software selection interface for the shift cable, feedback can be sent to the background server of the MATLAB software, and the server updates the software for generating the shift cable in real time according to the user's feedback information.

[0080] Step S104: Generate the shift cable based on the software to obtain the initial shift cable.

[0081] In this embodiment, after the software for generating the shift cable is selected, the shift cable is processed by the selected software to generate the initial shift cable. After the user selects the software for generating the shift cable, the MATLAB software will automatically generate the shift cable according to the selected software to obtain the initial shift cable.

[0082] In this embodiment, the instruction for the user's shift cable is parsed to obtain the import path; the shift cable is selected according to the import path; the software for generating the shift cable is selected according to the selection result; and the shift cable is generated based on the software to obtain the initial shift cable, so that the shift cable to be generated can be quickly generated according to the import path to obtain the initial shift cable.

[0083] Reference Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of the shift point determination method of the present invention.

[0084] Based on the above first embodiment, step S30 of the shift point determination method in this embodiment specifically includes:

[0085] Step S301: Obtain the curve information of the comprehensive fuel consumption and vehicle speed in the test field rules.

[0086] It should be understood that there is relevant information for comprehensive fuel consumption testing in the test field rules. When the user selects the test field, the curve information of the comprehensive fuel consumption and vehicle speed to be tested in the corresponding test field rules can be obtained and the curve information can be identified.

[0087] Step S302: Read the generated initial shift cable information.

[0088] Step S303: Perform screening and marking at the corresponding positions on the curve information based on the initial shift cable information to obtain the shift points.

[0089] It should be noted that after obtaining the curve information, the shift point positions can be marked and screened on the curve information according to the shift cable information in the initial shift cable to obtain the shift points. The table in the generated initial shift cable is read through MATLAB software, and the shift points in the shift cable are marked according to the test field rules to obtain the shift points.

[0090] Before the test, the generated initial shift cable is introduced into the test operation table. The operation table reads the initial shift cable information and marks the shift points at the corresponding positions on the curve of the comprehensive fuel consumption and vehicle speed on the screen of the test roller, so that the test personnel can perform shift operations during the test.

[0091] In this embodiment, by obtaining the curve information of the comprehensive fuel consumption and vehicle speed in the test field rules; reading the generated initial shift cable information; performing screening and marking at the corresponding positions on the curve information based on the initial shift cable information to obtain the shift points, the shift points can be quickly and accurately determined from the initial shift cable, improving the efficiency and accuracy of shift point generation.

[0092] Reference Figure 5 , Figure 5Schematic flowchart of the fourth embodiment of the shift point determination method according to the present invention.

[0093] Based on the above first embodiment, after the step S30, the shift point determination method of this embodiment further includes:

[0094] Step S31: Conduct a comprehensive fuel consumption test through the shift point and obtain test data.

[0095] In this embodiment, after generating the shift point, a generated shift point table is obtained. The shift point table contains time information and gear information for the comprehensive fuel consumption test. For example, at the first second of the comprehensive fuel consumption test, the gear is 0, and at the 30th second of the comprehensive fuel consumption test, the gear is 5. The comprehensive fuel consumption test can be carried out through the above shift point and the information of the shift time to obtain test data.

[0096] When conducting the comprehensive fuel consumption test, it is necessary to first connect the corresponding calibration equipment to collect data. After the equipment is connected, the driver and automotive calibration software need to be installed synchronously. For example, INCA software, or other software that can perform automotive calibration can also be used. This embodiment takes INCA software as an example for illustration. After installing the driver and automotive calibration software, it is also necessary to connect the calibration equipment to the OBD (On Board Diagnostics) port of the vehicle, and collect XCP (Explicit Control Protocol) data and CAN bus (Controller Area Network) data through the INCA software, so as to obtain test file data in the format of ".mdf" or ".dat".

[0097] Step S32: Obtain shift parameters based on the test data.

[0098] The shift parameters include at least one of time, gear, vehicle speed, engine speed, and engine load.

[0099] It should be noted that when conducting the comprehensive fuel consumption test, the collected data includes test data such as time information, gear information, vehicle speed information, engine speed information, and engine load information.

[0100] After the user completes the comprehensive fuel consumption test, the collected test data can be imported into the MATLAB software platform. The user can choose to import one or more test data for comparison and analysis.

[0101] After obtaining the test data, the shifting parameters such as time, gear position, vehicle speed, engine speed, and engine load in the test data can be read. The user can search for the variable parameters to be analyzed or viewed at the variable selection, determine the variable parameters to be viewed, and can also add and delete variable parameters in the interface.

[0102] Step S33: Generate an analysis graph of time-gear position-vehicle speed based on the shifting parameters.

[0103] In a specific implementation, when the user needs to view the test analysis graph of shifting time, gear position, and vehicle speed, when selecting the shifting parameters as time, gear position, and vehicle speed, an analysis graph of time-gear position-vehicle speed is generated, as Figure 6 shown, Figure 6 which is the analysis graph of time-gear position-vehicle speed in this embodiment, Figure 6 where the abscissa is the time parameter, the left ordinate is the gear position parameter, the right ordinate is the vehicle speed parameter, 1 in the analysis graph refers to the vehicle speed change curve, and 2 refers to the gear position change curve.

[0104] Step S34: Analyze the time, gear position, and vehicle speed to obtain optimized data.

[0105] After obtaining the time-gear position-vehicle speed analysis graph, it can be analyzed whether the corresponding time points in the curves in the graph can be optimized. When it is analyzed that a certain time point needs to be optimized, the specific time point can be determined to obtain the optimized data. The optimized data can include the specific time point and the corresponding shifting parameters.

[0106] Step S35: Update the initial shifting line with the optimized data.

[0107] After obtaining the optimized data, it is possible to return to the parameter table for modification, input the corresponding parameters into the shifting line generation tool, and update the initial shifting line to achieve the optimization of the initial shifting line.

[0108] Furthermore, when the analysis graph that the user needs to view is the relationship graph of engine load, vehicle speed, and time, an analysis graph of time-engine load-vehicle speed can be generated based on the shifting parameters; analyze the time, engine load, and vehicle speed to obtain optimized data.

[0109] As Figure 7 shown, Figure 7 which is the analysis graph of time-engine load-vehicle speed in this embodiment, Figure 7The abscissa is the time parameter, the left side of the ordinate is the engine load parameter, and the right side of the ordinate is the vehicle speed parameter. In the analysis graph, 3 refers to the vehicle speed change curve, and 4 refers to the engine load change curve. The user can analyze the variable parameters in the time-engine load-vehicle speed analysis graph and determine whether optimization is needed. When the user needs to optimize the parameters, the specific time point and the corresponding parameter information can be determined to obtain the optimization data. The parameter table can be returned for modification, and the corresponding parameters can be input into the shift line generation tool to update the initial shift line and achieve the optimization of the initial shift line.

[0110] Correspondingly, when the analysis graph that the user needs to view is the relationship graph of engine speed, vehicle speed, and time, the time-engine speed-vehicle speed analysis graph can be generated based on the shift parameters; the time, engine speed, and vehicle speed are analyzed to obtain the optimization data.

[0111] As Figure 8 shown, Figure 8 This is the time-engine speed-vehicle speed analysis graph in this embodiment. Figure 8 The abscissa is the time parameter, the left side of the ordinate is the engine speed parameter, and the right side of the ordinate is the vehicle speed parameter. In the analysis graph, 5 refers to the vehicle speed change curve, and 6 refers to the engine speed change curve. The user can analyze the variable parameters in the time-engine speed-vehicle speed analysis graph and determine whether optimization is needed. When the user needs to optimize the parameters, the specific time point and the corresponding parameter information can be determined to obtain the optimization data. The parameter table can be returned for modification, and the corresponding parameters can be input into the shift line generation tool to update the initial shift line and achieve the optimization of the initial shift line.

[0112] As Figure 9 shown, Figure 9 This is the overall flow schematic diagram of the shift point determination method. After the user imports the shift line, the software for generating the shift line is selected to generate the initial shift line, and the test field data is selected to obtain the test field rules of the test field data. The initial shift line is marked and screened through the test field rules, the shift points are exported, and the comprehensive fuel consumption test is carried out through the shift points to generate the test data. The test data is imported into the software to select the variables to be viewed, the analysis graph is generated, and the variables are analyzed to obtain the optimization data so as to optimize the initial shift line.

[0113] In this embodiment, comprehensive fuel consumption tests are carried out through the shift points, and test data are obtained; based on the test data, shift parameters are obtained; based on the shift parameters, an analysis chart of time-gear-vehicle speed is generated; the time, gear, and vehicle speed are analyzed to obtain optimization data; the initial shift line is updated through the optimization data, and the initial shift line can be optimized by analyzing the specific time points that need to be optimized and the improvability, so as to obtain the optimal shift line, and the test data can be quickly analyzed to realize the timely and convenient optimization of the shift line.
