Description

Technical Field

[0001] This application relates to the field of vehicle emission control technology, and in particular to a DPF regeneration method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] Most of the particulate matter emitted by an engine consists of tiny carbon or carbide particles. A Diesel Particulate Filter (DPF) is a particulate filter installed in the engine system that captures and collects particulate matter generated during engine operation, preventing it from entering the air.

[0003] Typically, the carbon particles that a DPF can hold are limited. To prevent damage to the DPF, it needs to be regenerated, which reacts the captured carbon particles into CO2 and releases it into the atmosphere. DPF regeneration is divided into driving regeneration and parking regeneration. Compared to parking regeneration, driving regeneration offers better fuel economy and saves users waiting time; therefore, parking regeneration should be avoided as much as possible. However, the inventors discovered that for some vehicles that operate at low speeds and low loads for extended periods, it is difficult to initiate driving regeneration or to complete it successfully. Summary of the Invention

[0004] Based on this, embodiments of this application provide a DFP regeneration method, apparatus, device, and computer-readable storage medium that can save fuel consumption and improve the user's driving experience.

[0011] The correction module is used to correct the vehicle's regenerated carbon load threshold based on the operating condition indicators.

[0012] The control module is used to control the DPF regeneration according to the modified vehicle regeneration carbon load threshold.

[0015] The technical solution provided in this application determines the vehicle's operating condition indicators by analyzing the vehicle's driving data in the most recent time period. Based on these indicators, the vehicle's regenerative carbon load threshold is adjusted. Specifically, different regenerative carbon load thresholds are set for vehicles operating under different conditions, ensuring that the thresholds match the vehicle's actual operating conditions. For vehicles operating at low speeds and low loads for extended periods, adjusting the regenerative carbon load threshold allows them to quickly find suitable active regeneration opportunities, reducing the probability of missing these opportunities and requiring parking for regeneration. This saves fuel consumption and reduces user waiting time, improving the user's driving experience. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure.

[0021] The vehicle continuously monitors the carbon load in the DPF during driving. If the detected carbon load exceeds the driving regeneration carbon load threshold, it is determined that the vehicle needs to switch to driving regeneration mode. In driving regeneration mode, the engine degrades diesel combustion through the fuel and air systems and increases the amount of fuel injection to raise the DPF temperature. When the increased temperature meets the carbon deposit combustion temperature, the carbon deposits in the DPF can be fully burned. After the carbon deposits are fully burned, the amount of fuel injection is reduced and the vehicle switches back to normal driving mode.

[0022] However, for some vehicles that operate at low speeds and low loads for extended periods, such as sanitation trucks or dump trucks, it is difficult to find a suitable time for active regeneration. Often, they need to be stopped and manually switched to parking regeneration mode, increasing fuel consumption and user waiting time. Meanwhile, for vehicles that operate at high speeds and high loads for extended periods, such as tractor-trailers or long-haul trucks, frequent regeneration occurs, affecting not only the driving experience but also increasing fuel consumption. Therefore, the technical solution provided in this application aims to solve the technical problems existing in conventional technologies.

[0023] It should be noted that the DPF regeneration method provided in this application embodiment can be executed by a DPF regeneration device, which can be implemented in hardware and / or software, and is generally integrated into an electronic device. Optionally, the electronic device can be a cloud-based device or a control device in the vehicle. This application embodiment does not limit the specific form of the electronic device.

[0024] Figure 1 This is a schematic flowchart of a DPF regeneration method provided in an embodiment of this application. Figure 1 As shown, the method may include:

[0025] S101. Determine the vehicle's operating condition indicators based on the vehicle's driving data in the most recent time period.

[0026] Operating condition indicators refer to relevant metrics that reflect the vehicle's operating conditions within a recent time period. Examples include average operating speed, the percentage of time and mileage during which the vehicle speed exceeds a set speed value, and the percentage of time and mileage during which the Selective Catalytic Reduction (SCR) inlet temperature exceeds a set temperature value. Specifically, vehicle driving data from a period prior to the current time (e.g., driving data from the past month) can be obtained. This driving data includes, but is not limited to, vehicle speed, engine load, road conditions, and SCR inlet temperature. These driving data are statistically calculated according to a preset indicator calculation formula to obtain the vehicle's operating condition indicators for the recent time period.

[0027] S102. Based on the operating condition indicators, the vehicle's regenerated carbon load threshold is adjusted.

[0028] After obtaining the operating condition indicators, a corresponding regenerative carbon load threshold can be set for the vehicle based on these indicators. Thus, the regenerative carbon load threshold is not fixed but varies for vehicles operating under different conditions. Optionally, a correction value can be determined based on the operating condition indicators; this correction value can then be used to adjust the vehicle's regenerative carbon load threshold. For example, the correction value can be summed with the vehicle's regenerative carbon load threshold to obtain the corrected regenerative carbon load threshold.

[0029] As another optional implementation, S102 may include: determining a first correction factor based on operating condition indicators; and correcting the vehicle's driving carbon regeneration threshold according to the first correction factor.

[0030] For example, for vehicles whose operating condition indicators are greater than the first preset indicator value, i.e., vehicles that operate at high speed and high load for extended periods (such as tractor trucks or long-haul trucks), a larger first correction factor can be set (e.g., a first correction factor greater than 1 under this operating condition) to increase the vehicle's carbon load threshold for regeneration, thereby extending the active regeneration interval as much as possible while ensuring regeneration power and avoiding frequent regeneration. For vehicles whose operating condition indicators are less than the second preset indicator value, i.e., vehicles that operate at low speed and low load for extended periods (such as sanitation vehicles or dump trucks), a smaller first correction factor can be set (e.g., a first correction factor less than 1 under this operating condition) to reduce the vehicle's carbon load threshold for regeneration, enabling such vehicles to quickly find a suitable active regeneration opportunity during operation. For vehicles whose operating condition indicators are greater than or equal to the second preset indicator value and less than or equal to the first preset indicator value, the vehicle's carbon load threshold used in the previous regeneration can be maintained.

[0031] Understandably, when a vehicle leaves the factory, its regenerative carbon load threshold is fixed. As the vehicle continues to operate, its driving data is analyzed periodically to obtain operating condition indicators. These indicators are then used to adjust the regenerative carbon load threshold so that it is adapted to the vehicle's most recent operating conditions. In other words, the regenerative carbon load threshold is no longer fixed but varies for vehicles operating under different conditions.

[0032] S103. Control DPF regeneration according to the revised vehicle regeneration carbon load threshold.

[0033] After obtaining the revised driving regeneration carbon load threshold, the DPF can be controlled to regenerate based on the revised driving regeneration carbon load threshold during vehicle operation. For example, if the vehicle's carbon load is detected to exceed the aforementioned revised driving regeneration carbon load threshold, it indicates that carbon deposits need to be cleaned, otherwise it will affect engine performance. At this time, the vehicle can be controlled to enter driving regeneration mode to regenerate the DPF.

[0034] As an optional implementation, the process of controlling DPF regeneration based on the modified driving regeneration carbon load threshold may include: monitoring the vehicle's real-time operating data when the vehicle's carbon load is detected to be greater than the modified driving regeneration carbon load threshold; and controlling DPF regeneration when it is determined that the real-time operating data meets the preset regeneration conditions.

[0035] Real-time operating data refers to data used to reflect the current operating conditions of the vehicle, which may include, but is not limited to, vehicle speed, current road type, engine load, and SCR inlet temperature.

[0036] During vehicle operation, when the vehicle's carbon load is detected to be greater than the corrected driving-based regeneration carbon load threshold, the vehicle's real-time operating data is monitored. If the real-time operating data confirms that the preset regeneration conditions are met, DPF regeneration is then controlled. For example, if the vehicle's carbon load is detected to be greater than the corrected driving-based regeneration carbon load threshold, and it is detected that the vehicle is traveling on a highway for more than a preset duration, while the SCR inlet temperature is higher than a preset temperature value, then DPF regeneration can be controlled.

[0037] When the carbon load of a vehicle exceeds the modified driving regeneration carbon load threshold, by monitoring and analyzing the vehicle's real-time operating data, the vehicle can regenerate the DPF in a more suitable environment (such as when the DPF temperature is higher), thereby improving the DPF regeneration power and economy.

[0038] The DPF regeneration method provided in this application determines the vehicle's operating condition indicators by analyzing the vehicle's driving data in the most recent time period. Based on these indicators, the method corrects the vehicle's driving regeneration carbon load threshold. Specifically, it sets different driving regeneration carbon load thresholds for vehicles operating under different conditions, ensuring that the thresholds match the actual operating conditions of the vehicle. For vehicles that operate at low speeds and low loads for extended periods, adjusting the driving regeneration carbon load threshold allows them to quickly find suitable active regeneration opportunities, reducing the probability of missing these opportunities and requiring parking regeneration. This saves fuel consumption and reduces waiting time for the user, improving the driving experience.

[0039] Figure 2This is another schematic flowchart illustrating the DPF regeneration method provided in this application embodiment. Based on the above embodiments, this embodiment further refines the relevant operations described above, such as... Figure 2 As shown, the method may include:

[0040] S201. Obtain the vehicle speed, SCR inlet temperature, road type, total mileage, and total driving time of the vehicles collected in the most recent time period.

[0041] Specifically, the vehicle is equipped with onboard sensors that can collect data on vehicle speed, SCR inlet temperature, and road type. Corresponding counters can be used to collect the vehicle's total mileage and total driving time in the most recent time period.

[0042] S202, determine the percentage of time during which the vehicle speed is greater than the set speed value within the total driving time, the percentage of time during which the SCR inlet temperature is greater than the set temperature value, the percentage of time during which the vehicle speed is greater than the set speed value within the specified driving road type, and the percentage of mileage during which the vehicle speed is greater than the set speed value within the total driving mileage.

[0043] By statistically calculating the vehicle speed over the total driving time, the following percentages are obtained: the first percentage of time during which the vehicle speed exceeds the set speed value, and the second percentage of time during which the vehicle speed exceeds the set speed value. Similarly, by statistically calculating the SCR inlet temperature, the percentage of time during which the SCR inlet temperature exceeds the set temperature value is obtained. Finally, the percentage of time during which the vehicle travels on designated roads within the total driving time is also calculated. The designated road type can be a road type with certain speed requirements, such as highways, national roads, and / or provincial roads.

[0044] S203. Determine the second correction factor corresponding to the first time percentage, the second time percentage, the third time percentage, and the mileage percentage.

[0045] Optionally, the second correction factor is directly proportional to the operating condition indicators "first time percentage", "second time percentage", "third time percentage", and "mileage percentage", respectively. That is, the greater the proportion of time the vehicle spends at higher speeds within the total driving time, the greater the second correction factor corresponding to the "first time percentage" of the operating condition indicator, and vice versa; the greater the proportion of time the vehicle spends at higher SCR inlet temperatures within the total driving time, the greater the second correction factor corresponding to the "second time percentage" of the operating condition indicator, and vice versa; the greater the proportion of time the vehicle spends on designated roads within the total driving time, the greater the second correction factor corresponding to the "third time percentage" of the operating condition indicator, and vice versa; the greater the proportion of mileage the vehicle spends at higher speeds within the total mileage, the greater the second correction factor corresponding to the "mileage percentage" of the operating condition indicator, and vice versa.

[0046] S204. Determine the first correction factor based on each of the second correction factors.

[0047] After obtaining the second correction factor corresponding to each operating condition indicator, the first correction factor can be determined by multiplying the second correction factors or by other calculation methods.

[0048] S205. Based on the first correction factor, the vehicle's regenerated carbon load threshold is corrected.

[0049] After obtaining the first correction factor, a preset calculation method can be used to calculate the first correction factor and the vehicle's driving carbon load threshold to obtain the corrected driving carbon load threshold. Optionally, the first correction factor can be multiplied by the vehicle's driving carbon load threshold to obtain the corrected driving carbon load threshold.

[0050] S206. Control DPF regeneration according to the revised vehicle regeneration carbon load threshold.

[0051] In this embodiment, the first correction factor is determined by the proportion of time during which the vehicle's speed exceeds a set speed value, the proportion of time during which the SCR inlet temperature exceeds a set temperature value, the proportion of time during which the vehicle's speed exceeds a set speed value within the total driving time in the most recent period, and the proportion of time during which the vehicle's speed exceeds a set speed value within the total driving mileage. This means that the first correction factor for the vehicle's regenerative carbon load threshold is determined by comprehensively considering multiple operating condition indicators, making the determined first correction factor more compatible with the vehicle's operating conditions. Thus, using the first correction factor to correct the vehicle's regenerative carbon load threshold ensures the adaptability of the corrected threshold. Furthermore, for vehicles operating at high speeds and high loads, a larger first correction factor is set, increasing the vehicle's regenerative carbon load threshold and extending the active regeneration interval for such vehicles to avoid frequent regeneration. For vehicles operating at low speeds and low loads, a smaller first correction factor is set, lowering the vehicle's regenerative carbon load threshold, enabling such vehicles to quickly find suitable active regeneration opportunities during driving, reducing the probability of missing active regeneration opportunities and requiring parking regeneration, thus saving fuel consumption and user waiting time.

[0052] In some embodiments, the vehicle speed, SCR inlet temperature, total mileage, and total driving time collected in the most recent time period can also be obtained. The mileage percentage of the vehicle speed within different speed ranges within the total mileage can be determined to obtain the speed distribution mileage percentage. The time percentage of the vehicle speed within different speed ranges within the total driving time can be determined to obtain the speed distribution time percentage. The time percentage of the SCR inlet temperature within different temperature ranges within the total driving time can be determined to obtain the SCR inlet temperature distribution time percentage. Then, the correction factors corresponding to the speed distribution mileage percentage, the speed distribution time percentage, and the SCR inlet temperature distribution time percentage are determined. Using the correction factors corresponding to the speed distribution mileage percentage, the speed distribution time percentage, and the SCR inlet temperature distribution time percentage, a total correction factor is determined. The total correction factor is then used to correct the vehicle regeneration carbon load threshold.

[0053] Of course, the vehicle's carbon load threshold can also be corrected by combining other operating conditions indicators of the vehicle in the most recent time period. The above-mentioned speed distribution mileage ratio, speed distribution time ratio, and SCR inlet temperature distribution time ratio are just examples. As long as the method of correcting the vehicle's carbon load threshold by using indicators that can reflect the vehicle's operating conditions is within the protection scope of the embodiments of this application.

[0054] In some scenarios, vehicles collect driving data through onboard sensors and transmit this data to the cloud via corresponding communication modules. The cloud analyzes the vehicle's driving data over a recent period to obtain vehicle operating condition indicators. Using these indicators, the cloud corrects the vehicle's regenerative carbon load threshold and controls DPF regeneration based on this corrected threshold. Leveraging the cloud's computing power to correct the regenerative carbon load threshold further improves the accuracy of the calculated threshold.
