Description

Technical Field

[0001] This disclosure relates to the field of vehicle range testing technology, specifically to a vehicle range testing method, apparatus, equipment, and medium. Background Technology

[0002] When a vehicle is undergoing CLTC range testing, the final range is affected by many factors. One factor is the laboratory equipment and personnel operation, another is the condition of the product being tested, and the last factor is the BMS software strategy and the timing of entering the DS2 stage. The first two factors are beyond the control of the vehicle manufacturer during testing, leaving only the last factor, the BMS software strategy and the SOC value at which the vehicle enters the DS2 stage, which the manufacturer can control.

[0003] Existing technologies mainly optimize the discharge strategy but do not calibrate the SOC value when entering the DS2 stage, resulting in large errors in the endurance results. Furthermore, they do not control the energy of the CSSE stage, which can easily exceed 10% and lead to experimental failure. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this disclosure is to provide a vehicle range testing method, apparatus, computer equipment, and storage medium, thereby increasing the range under test conditions and effectively improving the accuracy and success rate of range testing.

[0024] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, data stored, data displayed, etc.) and signals involved in this disclosure are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0026] Figure 1 This is a schematic flowchart of a vehicle range testing method proposed in one embodiment of the present disclosure.

[0027] It should be noted that the vehicle range testing method in this embodiment is executed by a vehicle range testing device, which can be implemented by software and / or hardware. The device can be configured in a computer device, which may include, but is not limited to, a terminal, a server, etc. For example, the terminal may be a mobile phone, a PDA, etc.

[0028] like Figure 1 As shown, the vehicle range testing method includes:

[0029] S101: When the vehicle enters the discharge mode, determine the vehicle's first charge value at the corresponding moment.

[0030] The vehicle in question can refer to the vehicle to be tested for CLTC range, such as a new energy vehicle.

[0031] Among them, the discharge mode can refer to the mode in which the vehicle begins to discharge during the CLTC range test.

[0032] The first battery level value can refer to the battery level of the vehicle at the moment it enters discharge mode. For example, it can be expressed as a percentage.

[0033] In this embodiment of the disclosure, when the vehicle enters the discharge mode, the initial battery level of the vehicle at the corresponding moment is determined, which can be used to verify the initial battery level of the vehicle during the CLTC range test, so as to avoid the test results being affected by an unhealthy battery level.

[0034] S102: When the first battery level is greater than or equal to a preset battery level threshold, the time point at which the vehicle enters the discharge mode is determined as the first time point.

[0035] The preset battery threshold can refer to a pre-set battery level used to determine whether a vehicle is eligible for the CLTC range test. For example, it can be set to 99%, or it can be flexibly adjusted according to the application scenario without restriction.

[0036] The first time point can refer to the time when the vehicle enters the discharge mode.

[0037] In this embodiment of the disclosure, when the first power value is greater than or equal to a preset power threshold, the time point at which the vehicle enters the discharge mode is determined as the first time point, which can provide a time anchor point for subsequent real-time calculation to determine the first discharge energy of the vehicle.

[0038] S103: Monitor the vehicle's real-time battery level when the vehicle speed is within the target speed range.

[0039] The target speed range can refer to the speed range determined based on the target speed of the vehicle during the CLTC range test.

[0040] The real-time battery level can refer to the battery level determined by real-time monitoring of the vehicle.

[0041] In other words, in this embodiment of the present disclosure, when the vehicle speed is within the target speed range, the vehicle's battery level can be monitored in real time to obtain the real-time battery level.

[0042] S104: When the real-time power value is detected to be less than or equal to the target power value, the corresponding time point is determined as the second time point.

[0043] The target battery level can refer to the battery level at which a vehicle can enter the DS2 stage during the CLTC range test.

[0044] The second time point can refer to the time point when the real-time battery level of the vehicle is detected to be less than or equal to the target battery level.

[0045] Optionally, in some embodiments, the target speed range and target battery level are determined based on the following method: determining the vehicle model information; determining the target speed of the vehicle during the CLTC range test and the target battery level for entering the DS2 stage based on the model information; and determining the target speed range based on the target speed, wherein the target speed falls within the target speed range. Therefore, the target speed range and target battery level can be accurately and quickly determined by combining the vehicle model information, thereby ensuring the adaptability of the obtained target speed range and target battery level to the range test process.

[0046] For example, when the target vehicle speed is V1, the range (V1-5, V1+5) can be taken as the target vehicle speed range.

[0047] S105: Determine the first discharge energy of the vehicle between the first time point and the current time point, and the second discharge energy between the second time point and the current time point.

[0048] In other words, in this embodiment of the present disclosure, after determining the second time point, the first discharge energy of the vehicle between the current time point and the first time point, and the second discharge energy between the current time point and the second time point can be calculated in real time. This can provide reliable data support for subsequent determination of whether the vehicle needs to be subject to power limiting.

[0049] S106: Determine the ratio of the second discharge energy to the first discharge energy, and when the ratio is greater than or equal to a preset threshold, limit the power of the vehicle.

[0050] The preset threshold can be flexibly set according to the application scenario. For example, it can be configured to 9.5% or 9%, without any restrictions.

[0051] In other words, in this embodiment of the present disclosure, after determining the second discharge energy and the first discharge energy, the ratio of the second discharge energy to the first discharge energy can be determined, and the obtained ratio can be compared with a preset threshold, thereby providing a reliable triggering basis for subsequent power limiting processing of the vehicle.

[0052] In this embodiment, when the vehicle enters discharge mode, a first battery level is determined at the corresponding moment; when the first battery level is greater than or equal to a preset battery level threshold, the time point at which the vehicle enters discharge mode is determined as a first time point; when the vehicle speed is within the target speed range, the real-time battery level is monitored; when the real-time battery level is detected to be less than or equal to the target battery level, the corresponding time point is determined as a second time point; the first discharge energy of the vehicle between the first time point and the current time point, and the second discharge energy between the second time point and the current time point are determined; the ratio of the second discharge energy to the first discharge energy is determined; when the ratio is greater than or equal to a preset threshold, the vehicle's power is limited. This increases the driving range under test conditions and effectively improves the accuracy and success rate of range testing.

[0053] Figure 2 This is a schematic flowchart of a vehicle range testing method according to another embodiment of this disclosure.

[0054] like Figure 2 As shown, the vehicle range testing method includes:

[0055] S201: When the vehicle enters the discharge mode, determine the vehicle's first charge value at the corresponding moment.

[0056] S202: When the first battery level is greater than or equal to a preset battery level threshold, the time point at which the vehicle enters the discharge mode is determined as the first time point.

[0057] S203: Monitor the vehicle's real-time battery level when the vehicle speed is within the target speed range.

[0058] The descriptions of S201-S203 can be found in the above embodiments, and will not be repeated here.

[0059] S204: Determine the lookup voltage value of the target power value in the target association table.

[0060] The target association table can refer to a pre-configured table used to indicate the relationship between vehicle battery level, cell voltage, and bus current data.

[0061] Optionally, in some embodiments, the bus current data of the vehicle at the target speed can be determined; the open-circuit voltage change data corresponding to the vehicle's battery cells and the bus current data can be obtained; and a target association table can be generated based on the bus current data and the open-circuit voltage change data. This ensures that the obtained target association table accurately indicates the correlation between the bus current data and the open-circuit voltage change data.

[0062] Among them, the voltage value in the table lookup table can refer to the voltage value associated with the target power value in the target association table.

[0063] In this embodiment of the disclosure, when the lookup voltage value of the target power value is determined in the target association table, reliable data support can be provided for subsequently correcting the real-time power value to the target power value.

[0064] S205: When the real-time battery level is detected to be greater than the target battery level, determine the minimum voltage of a single battery cell in the vehicle.

[0065] In other words, in this embodiment of the present disclosure, when the real-time power value is detected to be greater than the target power value, the minimum voltage of the vehicle's battery cell can be determined, thereby providing reliable data support for subsequently correcting the real-time power value to the target power value.

[0066] S206: When the lowest voltage of a single battery cell in the vehicle is less than or equal to the voltage value looked up in the table, the real-time battery level will be corrected to the target battery level.

[0067] In other words, this embodiment of the present disclosure can determine the lookup voltage value of the target battery level in the target association table; when the real-time battery level is detected to be greater than the target battery level, the minimum voltage of a single battery cell in the vehicle is determined; when the minimum voltage of a single battery cell in the vehicle is less than or equal to the lookup voltage value, the real-time battery level is corrected to the target battery level. Therefore, when the real-time battery level is greater than the target battery level, it is possible to determine whether the real-time battery level needs correction based on the comparison between the minimum voltage of a single battery cell and the lookup voltage value, thereby effectively improving the robustness of the testing process.

[0068] S207: When the real-time power value is detected to be less than or equal to the target power value, the corresponding time point is determined as the second time point.

[0069] S208: Determine the first discharge energy of the vehicle between a first time point and the current time point, and the second discharge energy between a second time point and the current time point.

[0070] S209: Determine the ratio of the second discharge energy to the first discharge energy, and when the ratio is greater than or equal to a preset threshold, perform power limiting on the vehicle.

[0071] The descriptions of S207-S209 can be found in the above embodiments, and will not be repeated here.

[0072] In this embodiment, the target battery level is determined by looking up the voltage value in a target association table. When the real-time battery level is found to be greater than the target battery level, the minimum voltage of a single battery cell in the vehicle is determined. When the minimum voltage of a single battery cell in the vehicle is less than or equal to the lookup voltage value, the real-time battery level is corrected to the target battery level. Therefore, when the real-time battery level is greater than the target battery level, the comparison between the minimum voltage of a single battery cell and the lookup voltage value can be used to determine whether the real-time battery level needs correction, thereby effectively improving the robustness of the testing process.

[0073] Figure 3 This is a schematic flowchart of a vehicle range testing method according to another embodiment of this disclosure.

[0074] like Figure 3 As shown, the vehicle range testing method includes:

[0075] S301: Determine the charging process data of the vehicle before conducting the CLTC range test, including the initial charge value, the final charge value, and the charging energy value.

[0076] The initial charge value can refer to the charge value of the vehicle when it first starts charging.

[0077] The final battery level can refer to the battery level when the vehicle exits charging mode.

[0078] Among them, charging energy value can refer to the cumulative energy value acquired by the vehicle during the charging process.

[0079] S302: Determine the result of the charging energy value based on the initial power value and the final power value, wherein the result is used to indicate whether the charging energy value is valid.

[0080] Optionally, in some embodiments, when determining the charging energy value based on the initial and final power values, the charging energy value may be determined to be valid if the initial power value is less than 1% and the final power value is equal to 100%, otherwise the charging energy value may be determined to be invalid.

[0081] In other words, in this embodiment of the disclosure, charging process data of the vehicle before conducting the CLTC range test can be determined. This charging process data includes an initial charge level, a final charge level, and a charging energy value. Based on the initial and final charge levels, a determination result for the charging energy value is made, indicating whether the charging energy value is valid. Therefore, a reliable basis for determining whether the charging energy value can be applied to the vehicle testing process can be provided.

[0082] S303: When the vehicle enters discharge mode, determine the vehicle's first charge level at the corresponding moment.

[0083] S304: When the first battery level is greater than or equal to a preset battery level threshold, the time point at which the vehicle enters the discharge mode is determined as the first time point.

[0084] S305: Monitors the vehicle's real-time battery level when the vehicle speed is within the target speed range.

[0085] For details on S303-S305, please refer to the above embodiments, and they will not be repeated here.

[0086] S306: If the determination result indicates that the charging energy value is valid, then when the real-time power value is detected to be greater than the target power value, the first discharge energy of the vehicle between the first time point and the current time point is determined.

[0087] In other words, in this embodiment of the present disclosure, if the determination result indicates that the charging energy value is valid, then when the real-time power value is detected to be greater than the target power value, the first discharge energy of the vehicle between the first time point and the current time point can be determined, thereby providing reliable data support for the subsequent determination of the vehicle's used power value.

[0088] S307: Determine the vehicle's used power level based on the vehicle's charging and discharging efficiency, charging energy value, and first discharge energy.

[0089] The used battery level indicates the amount of battery power the vehicle has used since entering discharge mode. This used battery level can be expressed as a percentage.

[0090] Among these, the vehicle's charging and discharging efficiency can be obtained by testing the vehicle in advance.

[0091] In this embodiment of the disclosure, when the used power value of the vehicle is determined based on the vehicle's charging and discharging efficiency, charging energy value, and first discharging energy, reliable data support can be provided for subsequently correcting the real-time power value to the target power value.

[0092] S308: When the sum of the target power value and the used power value is greater than or equal to 1, the real-time power value will be corrected to the target power value.

[0093] It is understandable that when the sum of the target battery value and the used battery value is greater than or equal to 1, it indicates that the vehicle's actual battery value at the current moment is less than or equal to the target battery value. Therefore, the real-time battery value can be corrected to the target battery value.

[0094] In other words, in this embodiment of the present disclosure, if the determination result indicates that the charging energy value is valid, then when the real-time power value is detected to be greater than the target power value, the first discharge energy of the vehicle between the first time point and the current time point is determined; based on the charging energy value and the first discharge energy, the used power value of the vehicle is determined; when the sum of the target power value and the used power value is greater than or equal to 1, the real-time power value is corrected to the target power value. Therefore, when the determination result indicates that the charging energy value is valid, the real-time power value of the vehicle can be corrected by combining the charging energy value, thereby further improving the robustness of the vehicle testing process.

[0095] S309: When the real-time power value is detected to be less than or equal to the target power value, the corresponding time point is determined as the second time point.

[0096] S310: Redetermine the first discharge energy of the vehicle between the first time point and the current time point, and the second discharge energy between the second time point and the current time point.

[0097] S311: Determine the ratio of the second discharge energy to the first discharge energy, and when the ratio is greater than or equal to a preset threshold, perform power limiting on the vehicle.

[0098] For details on S309-S311, please refer to the above embodiments, and they will not be repeated here.

[0099] In this embodiment, charging process data of the vehicle before the CLTC range test is determined. This charging process data includes initial battery level, final battery level, and charging energy value. Based on the initial and final battery levels, a determination result for the charging energy value is established, indicating whether the charging energy value is valid. This provides a reliable basis for determining whether the charging energy value can be applied to the vehicle testing process. If the determination result indicates that the charging energy value is valid, when the real-time battery level is detected to be greater than the target battery level, the first discharge energy of the vehicle between the first time point and the current time point is determined. Based on the charging energy value and the first discharge energy, the vehicle's used battery level is determined. When the sum of the target battery level and the used battery level is greater than or equal to 1, the real-time battery level is corrected to the target battery level. Therefore, when the determination result indicates that the charging energy value is valid, the real-time battery level can be corrected by combining it with the charging energy value, thereby further improving the robustness of the vehicle testing process.

[0100] In summary, as described in the above embodiments, Figure 4 As shown, Figure 4 Based on the data setting flowchart proposed in this disclosure, the maximum vehicle speed requirement V1 (i.e., the target vehicle speed), the bus circuit I1 (i.e., the bus current data) at vehicle speed V1, the I1-*OCV table (i.e., the target association table), the optimal SOC value for the vehicle to enter the DS2 stage is SOC1 (i.e., the target charge value) and the vehicle charging and discharging efficiency A (i.e., the vehicle charging and discharging efficiency) can be determined based on the steps shown in the figure.

[0101] like Figure 5 As shown, Figure 5 According to a test procedure diagram proposed in this disclosure, the vehicle can be discharged to 0% SOC first, and then fully charged for a standard range test.

[0102] like Figure 6 As shown, Figure 6 According to another test procedure diagram proposed in this disclosure, the standard range test can be conducted directly after the vehicle is fully charged without considering the initial charge value of the vehicle before charging.

[0103] For example, in this embodiment of the present disclosure, when the vehicle is charging, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the charging strategy proposed in this disclosure. W1 represents the aforementioned charging energy value.

[0104] When the preset battery threshold is 99% and the preset threshold is 9.5%, such as Figure 8 As shown, Figure 8 This is a schematic diagram of the discharge strategy proposed in this disclosure. Other power limiting amplitudes can also be used when limiting the power of the vehicle, and there are no restrictions on this.

[0105] Figure 9 This is a schematic diagram of the structure of a vehicle range testing device according to an embodiment of the present disclosure.

[0106] like Figure 9 As shown, the vehicle range testing device 90 includes:

[0107] The first determining module 901 is used to determine the first charge value of the vehicle at the corresponding time when the vehicle enters the discharge mode.

[0108] The second determining module 902 is used to determine the time point when the vehicle enters the discharge mode as the first time point when the first power value is greater than or equal to a preset power threshold.

[0109] The monitoring module 903 is used to monitor the real-time battery level of the vehicle when the vehicle speed is within the target speed range.

[0110] The third determining module 904 is used to determine the corresponding time point as the second time point when the real-time power value is detected to be less than or equal to the target power value;

[0111] The fourth determining module 905 is used to determine the first discharge energy of the vehicle between the first time point and the current time point, and the second discharge energy between the second time point and the current time point;

[0112] The fifth determining module 906 is used to determine the ratio of the second discharge energy to the first discharge energy, and to limit the power of the vehicle when the ratio is greater than or equal to a preset threshold.

[0113] It should be noted that the foregoing explanation of the vehicle range testing method also applies to the vehicle range testing device in this embodiment, and will not be repeated here.

[0114] In this embodiment, when the vehicle enters discharge mode, a first battery level is determined at the corresponding moment; when the first battery level is greater than or equal to a preset battery level threshold, the time point at which the vehicle enters discharge mode is determined as a first time point; when the vehicle speed is within the target speed range, the real-time battery level is monitored; when the real-time battery level is detected to be less than or equal to the target battery level, the corresponding time point is determined as a second time point; the first discharge energy of the vehicle between the first time point and the current time point, and the second discharge energy between the second time point and the current time point are determined; the ratio of the second discharge energy to the first discharge energy is determined; when the ratio is greater than or equal to a preset threshold, the vehicle's power is limited. This increases the driving range under test conditions and effectively improves the accuracy and success rate of range testing.

Figure 10 The computer device 12 shown is merely an example and should not be construed as limiting the functionality and scope of use of the embodiments disclosed herein.

The components of the computer device 12 may include, but are not limited to: one or more processors or processing units 16, system memory 28, and a bus 18 connecting different system components (including system memory 28 and processing unit 16).

This communication can be performed via input / output (I / O) interface 22. Furthermore, computer device 12 can also communicate with one or more networks (e.g., local area network (LAN), wide area network (WAN), and / or public networks, such as the Internet) via network adapter 20. As shown, network adapter 20 communicates with other modules of computer device 12 via bus 18. It should be understood that, although not shown in the figures, other hardware and / or software modules can be used in conjunction with computer device 12, including but not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data backup storage systems.
