Description

Technical Field

[0001] The present invention relates to automotive component technology, and more particularly to a method, apparatus, electronic device, and storage medium for interrupting the regeneration of a particulate filter. Background Technology

[0002] With the widespread application of direct injection technology in gasoline engines, while improving fuel economy, it also results in higher particulate emissions compared to traditional port injection engines. A particulate filter, a ceramic filter installed in the exhaust system of a car engine, captures and filters particulate matter before it enters the atmosphere, reducing the amount of particulate matter emitted by the vehicle. After capturing a certain amount of particulate matter, the particulate filter needs to undergo combustion cleaning, i.e., regeneration.

[0003] Currently, the regeneration process of particulate filters is often manually interrupted based on human experience when it is deemed unsuitable to continue regeneration. However, this manual interruption method is prone to errors due to inaccurate judgments. For example, interrupting regeneration too early affects the regeneration effect, while interrupting it too late affects the lifespan of vehicle components, or even causes damage to them. Therefore, there is an urgent need for a method that can quickly and accurately control the interruption of particulate filter regeneration. Summary of the Invention

[0004] This invention provides a method, apparatus, electronic device, and storage medium for interrupting the regeneration of a particulate filter, enabling automatic determination of whether to interrupt regeneration during the particulate filter regeneration process without manual intervention, thereby improving the accuracy of particulate filter regeneration interruption and ensuring regeneration effect, user safety, and component lifespan.

[0007] The current correction factor is determined based on the engine model, the current ignition efficiency, and the current air-fuel ratio;

[0008] The remaining regeneration time is determined based on the engine model, the current correction factor, and the current engine power.

[0009] If the remaining time of the current regeneration is detected to meet the first regeneration interruption condition, the particle trap of the target vehicle is controlled to interrupt regeneration.

[0010] Secondly, embodiments of the present invention provide a particle trap regeneration interruption device, comprising:

[0011] The vehicle parameter acquisition module is used to acquire the engine model, current ignition efficiency, current air-fuel ratio and current engine power of the target vehicle during the particulate filter regeneration process.

[0014] The interruption regeneration control module is used to control the particle trap of the target vehicle to interrupt regeneration if it is detected that the remaining duration of the current regeneration meets the first regeneration interruption condition.

[0015] Thirdly, embodiments of the present invention provide an electronic device, the electronic device comprising:

[0016] One or more processors;

[0017] Memory, used to store one or more programs;

[0018] When the one or more programs are executed by the one or more processors, the one or more processors implement the particle trap regeneration interrupt method as provided in any embodiment of the present invention.

[0019] Fourthly, embodiments of the present invention provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the particle trap regeneration interruption method as provided in any embodiment of the present invention.

[0020] The technical solution of this invention involves acquiring the engine model, current ignition efficiency, current air-fuel ratio, and current engine power of the target vehicle during the particulate filter regeneration process; determining a current correction factor based on the engine model, current ignition efficiency, and current air-fuel ratio; determining the remaining regeneration time based on the engine model, current correction factor, and current engine power; and controlling the particulate filter of the target vehicle to interrupt regeneration if the remaining regeneration time meets a first regeneration interruption condition. This automatically determines whether to interrupt regeneration during the particulate filter regeneration process without manual intervention, improving the accuracy of particulate filter regeneration interruption, reducing damage to various components in the target vehicle during the regeneration process, ensuring both regeneration effectiveness and the service life of components in the target vehicle, thereby improving the safety of users in the target vehicle.

[0030] Example 1

[0031] Figure 1 This is a flowchart of a particulate filter regeneration interruption method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the regeneration of a target vehicle's particulate filter is automatically interrupted during the regeneration process. This method can be executed by a particulate filter regeneration interruption device, which can be implemented in hardware and / or software and can be configured in an electronic device. For example... Figure 1 As shown, the method includes:

[0032] S110. During the particulate filter regeneration process, obtain the engine model, current ignition efficiency, current air-fuel ratio and current engine power of the target vehicle.

[0033] The particulate filter can include a gasoline particulate filter (GPF) and a diesel particulate filter (DPF). The target vehicle can be a vehicle undergoing particulate filter regeneration. During the vehicle's operation, the particulate filter captures and filters particulate emissions before they enter the atmosphere, reducing the vehicle's soot particulate emissions. As the particulate filter captures an increasing amount of soot particles, the target vehicle needs to undergo particulate filter regeneration to ensure its proper operation and filtration effectiveness.

[0034] Specifically, after the target vehicle starts the particulate filter regeneration operation, the controller in the target vehicle can obtain the engine model, current ignition efficiency, current air-fuel ratio and current engine power of the target vehicle, and thus monitor the operating condition of the target vehicle in real time through the above parameters.

[0035] For example, if the driver is unable to control the target vehicle to regenerate the particulate filter, the vehicle can be driven to the nearest 4S dealership for a parking regeneration operation. For instance, the operator connects a diagnostic tool to the vehicle, sends a regeneration command through the tool, and sends an interrupt command when necessary, thus completing the parking regeneration. After the regeneration is complete, repairs can also be performed to address the driver's inability to control the particulate filter regeneration.

[0036] S120. Based on the engine model, current ignition efficiency, and current air-fuel ratio, determine the current correction factor.

[0037] Here, the correction factor can refer to a parameter used to adjust the parameter value. The correction factor can be understood as a correction parameter. The current correction factor can refer to a parameter used to correct for the current ignition efficiency and the current air-fuel ratio.

[0038] Specifically, the set of correction factors between ignition efficiency and air-fuel ratio in the target vehicle is determined based on the engine model, and the current correction factor corresponding to the current ignition efficiency and current air-fuel ratio is determined from the set of correction factors corresponding to the target vehicle based on the current ignition efficiency and current air-fuel ratio.

[0039] S130. Based on the engine model, current correction factor, and current engine power, determine the remaining duration of current regeneration.

[0040] The remaining regeneration time refers to the time required for the target vehicle to complete its ongoing regeneration operation. As regeneration continues, the remaining regeneration time should decrease. It can be understood as a countdown.

[0041] Specifically, the current correction factor and the current engine power are multiplied to determine the corrected current engine power. The corrected current engine parameters are then multiplied with preset parameters to determine the multiplication result. Based on the engine model, the correspondence between each multiplication result and the remaining regeneration time for the target vehicle is determined. Based on the determined multiplication results, the remaining regeneration time required for the target vehicle to regenerate is determined from this correspondence.

[0042] For example, when regeneration of the particle trap is activated, a timer can be started, which can display the remaining regeneration time in real time. If the remaining regeneration time drops to 0, a logic value of 1 is output. "1" indicates that a regeneration interrupt signal should be issued at this time. This bit has a high priority; the regeneration operation should be interrupted even if regeneration is not complete.

[0043] S140. If the remaining time of the current regeneration is detected to meet the first regeneration interruption condition, the particle trap of the target vehicle is controlled to interrupt regeneration.

[0044] The first regeneration interruption condition can refer to the condition under which the regeneration of the particulate trap must be stopped, thereby avoiding damage to certain components in the target vehicle or a reduction in their service life, while ensuring the safety of the people inside the vehicle.

[0045] Specifically, if the remaining regeneration time is detected to have reached a preset time, indicating that the remaining regeneration time meets the first regeneration interruption condition, the particle trap of the target vehicle is controlled to interrupt regeneration. For example, the preset time can be, but is not limited to, 0 seconds or the time required to interrupt regeneration.

[0046] The technical solution of this invention obtains the engine model, current ignition efficiency, current air-fuel ratio, and current engine power of the target vehicle during the particulate filter regeneration process; determines the current correction factor based on the engine model, current ignition efficiency, and current air-fuel ratio; determines the current remaining regeneration time based on the engine model, current correction factor, and current engine power; and controls the particulate filter of the target vehicle to interrupt regeneration if the current remaining regeneration time meets the first regeneration interruption condition. This automatically determines whether to interrupt regeneration during the particulate filter regeneration process without manual intervention, improving the accuracy of particulate filter regeneration interruption, reducing damage to various components in the target vehicle during the regeneration process, ensuring both regeneration effectiveness and the service life of components in the target vehicle, thereby improving the safety of users in the target vehicle.

[0047] Based on the above technical solution, the method further includes: if it is detected that the remaining time of the current regeneration does not meet the first regeneration interruption condition, then the target component information corresponding to the target component in the target vehicle is obtained, and the target component information includes the target operating parameters and / or the target component status; if it is detected that at least one target component information meets the second regeneration interruption condition, then the particle trap of the target vehicle is controlled to interrupt regeneration.

[0048] The target component can refer to an automotive part in the target vehicle that has precise requirements for its working environment or operating parameters. For example, the target component may include, but is not limited to, engines and turbochargers that have specific operating temperature requirements. Operating parameters can refer to the values ​​reached by the component during operation. For example, operating parameters may include, but are not limited to, vehicle speed and engine temperature. Component status can refer to the status information of the component. For example, engine status information may include, but is not limited to, whether the engine is operating normally or whether engine knocking has occurred. The second regeneration interruption condition can refer to the conditions under which the particulate filter regeneration stops based on the vehicle's operating conditions and the component's specifications.

[0049] Specifically, if the remaining regeneration time does not meet the first regeneration interruption condition, it indicates that the particulate filter regeneration has not yet been completed. In this case, the particulate filter regeneration continues, and the target component information corresponding to the target component in the target vehicle is acquired. If at least one target component information meets the second regeneration interruption condition, the particulate filter regeneration of the target vehicle can be interrupted even if the remaining regeneration time still does not meet the first regeneration interruption condition. This allows for automatic judgment on whether the particulate filter regeneration process should continue based on multiple pieces of information or parameters, improving the diversity of judgment criteria and the accuracy of particulate filter regeneration interruption, further ensuring regeneration effectiveness, user safety, and component lifespan.

[0050] Based on the above technical solution, the target operating parameters include at least one of the following: fuel tank level, particulate filter temperature, vehicle speed, engine temperature, exhaust flow resistance pressure, and turbocharger temperature; the second regeneration interruption condition includes at least one of the following: fuel tank level is lower than the preset low fuel level, particulate filter temperature is lower than the desired regeneration temperature, vehicle speed is lower than the desired regeneration speed for a continuous period of time reaching the preset interruption period, engine temperature is higher than the engine's maximum operating temperature, exhaust flow resistance pressure is greater than the preset pressure threshold, and turbocharger temperature is higher than the turbocharger's maximum operating temperature.

[0051] To meet regeneration requirements, which necessitate sufficiently high exhaust temperatures, the engine typically increases fuel consumption. Therefore, regeneration must be interrupted when the fuel tank level falls below the preset low fuel level. Similarly, if the particulate filter temperature is below the desired regeneration temperature (meaning there is no regeneration requirement), regeneration must be interrupted. After regeneration is interrupted, if the vehicle speed remains above the desired regeneration speed for a preset duration, the regeneration interruption is lifted or regeneration is restarted. The maximum engine operating temperature can be calibrated to 105°C. When the turbocharger temperature exceeds its maximum operating temperature, regeneration must be immediately interrupted to avoid damaging the turbocharger.

[0052] Specifically, if the fuel tank level is detected to be lower than a preset low fuel level, the particulate filter of the target vehicle will be controlled to stop active regeneration; and / or if the particulate filter temperature is detected to be lower than the desired regeneration temperature, the particulate filter of the target vehicle will be controlled to stop active regeneration; and / or if the vehicle speed is detected to be lower than the desired regeneration speed for a continuous period of time that reaches a preset interruption duration, the particulate filter of the target vehicle will be controlled to stop active regeneration; and / or if the engine temperature is detected to be higher than the engine's maximum operating temperature, the particulate filter of the target vehicle will be controlled to stop active regeneration; and / or if the exhaust flow resistance pressure is detected to be greater than a preset pressure threshold, the particulate filter of the target vehicle will be controlled to stop active regeneration; and / or if the turbocharger temperature is detected to be higher than the turbocharger's maximum operating temperature, the particulate filter of the target vehicle will be controlled to stop active regeneration.

[0053] For example, if no regeneration λ value request is generated, it can be understood that the particulate filter has no regeneration requirement and regeneration needs to be interrupted. Here, λ value can refer to the air-fuel ratio.

[0054] Based on the above technical solution, the target component status includes at least one of the following: engine status, oxygen sensor status, throttle status, engine temperature sensor status, particulate filter temperature sensor status, crankshaft position sensor status, and camshaft position sensor status; the second regeneration interruption condition includes at least one of the following: the engine status is in a knocking state or a stopped state, the oxygen sensor status is in a protected mechanism triggered state, the throttle status is in a state where the opening cannot be adjusted, the engine temperature sensor status is in an error state, the particulate filter temperature sensor status is in an error state, the crankshaft position sensor status is in an error state, and the camshaft position sensor status is in an error state.

[0055] Among these, "knock state" refers to the state of the engine after it has experienced knocking. "Stopping state" refers to the state where the engine has stopped rotating. "Triggered protection mechanism" refers to the activation of the oxygen sensor and its components' protection. "Throttle valve state: unable to adjust opening" can be understood as the throttle valve malfunctioning, damaged, or not working properly, which will cause the vehicle to enter limp-home mode and limp-home. "Particulate filter temperature sensor" can include, but is not limited to, upstream and downstream particulate filter temperature sensors.

[0056] Specifically, if the engine is detected to be in a knocking or stalled state, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the oxygen sensor is detected to have triggered a protection mechanism, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the throttle is detected to be unable to adjust its opening, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the engine temperature sensor is detected to be in an error state, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the particulate filter temperature sensor is detected to be in an error state, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the crankshaft position sensor is detected to be in an error state, the particulate filter of the target vehicle is controlled to stop active regeneration; and / or if the camshaft position sensor is detected to be in an error state, the particulate filter of the target vehicle is controlled to stop active regeneration.

[0057] Example 2

[0058] Figure 2 This is a flowchart of a particle trap regeneration interruption method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of determining the remaining regeneration time. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0059] S210. During the particulate filter regeneration process, obtain the engine model, current ignition efficiency, current air-fuel ratio and current engine power of the target vehicle.

[0060] S220. Based on the engine model, current ignition efficiency, and current air-fuel ratio, determine the current correction factor.

[0061] For example, S220 may include: determining a target two-dimensional chart from a preset set of two-dimensional charts based on the engine model; the two-dimensional chart includes a pre-calibrated correspondence between correction factors and ignition efficiency and air-fuel ratio; and determining a current correction factor from the target two-dimensional chart based on the current ignition efficiency and the current air-fuel ratio.

[0062] In a two-dimensional chart, the horizontal and vertical axes can be ignition efficiency or air-fuel ratio, respectively. For example, based on ignition efficiency (horizontal axis) and air-fuel ratio (vertical axis), a correction factor can be accurately determined from the two-dimensional chart. A preset set of two-dimensional charts refers to a collection of multiple pre-set two-dimensional charts. Each two-dimensional chart corresponds one-to-one with an engine model. A target two-dimensional chart refers to the two-dimensional chart corresponding to the engine model in a target vehicle.

[0063] S230. Determine the total engine power based on the current engine power and the power of multiple historical engines within a preset historical time period.

[0064] Within the preset historical timeframe, there are multiple historical moments. For example, the historical timeframe could be a period of time preceding the current moment. Each historical moment has a corresponding historical engine power. The total engine power can refer to the sum of the power outputs of multiple engines.

[0065] Specifically, the current engine power is added to the historical engine power within a preset historical time period to determine the total engine power corresponding to the target vehicle.

[0066] S240. Based on the engine model, current correction factor, and total engine power, determine the current remaining regeneration time.

[0067] Specifically, the current correction factor is multiplied by the total engine power to determine the corrected total engine power. Based on the engine model, the correspondence between the total engine power of each engine corresponding to the target vehicle and the remaining regeneration time is determined. Based on the determined corrected total engine power, the remaining regeneration time required for the target vehicle to regenerate is determined from this correspondence.

[0068] For example, S240 may include: determining a target one-dimensional chart from a preset set of one-dimensional charts based on the engine model; the one-dimensional chart includes a pre-calibrated correspondence between the corrected power and the countdown time; determining the corrected total engine power based on the current correction factor and the total engine power; and determining the current remaining regeneration time from the target one-dimensional chart based on the corrected total engine power.

[0069] In this context, the horizontal or vertical axis of the one-dimensional chart can be a pre-calibrated corrected power. For example, based on a pre-calibrated corrected power (horizontal or vertical axis), a countdown duration can be accurately determined from the one-dimensional chart. A preset set of one-dimensional charts can refer to a collection of multiple pre-set one-dimensional charts. Each one-dimensional chart corresponds one-to-one with an engine model. A target one-dimensional chart can refer to a one-dimensional chart corresponding to the engine model in a target vehicle.

[0070] S250. If the remaining time of the current regeneration is detected to meet the first regeneration interruption condition, the particle trap of the target vehicle is controlled to interrupt regeneration.

[0071] The technical solution of this invention determines the total engine power based on the current engine power and multiple historical engine power values ​​within a preset historical time period; it then determines the current remaining regeneration time based on the engine model, current correction factor, and total engine power. This allows for a more accurate determination of the current remaining regeneration time based on the sum of engine power over a period of time, avoiding the determination of a significantly different remaining regeneration time from the target vehicle based on the current engine power collected during a single period of large fluctuations. This further improves the accuracy of particulate filter regeneration interruption, reduces damage to various components in the target vehicle during the regeneration process, ensures the regeneration effect while also guaranteeing the service life of components in the target vehicle, and ultimately improves the safety of users in the target vehicle.

[0072] Based on the above technical solutions, Figure 3 An example diagram illustrating the process of determining the remaining regeneration time is provided. (See also...) Figure 3 Based on the current ignition efficiency and current air-fuel ratio, the current correction factor is determined from the target two-dimensional chart; based on the current engine power and multiple historical engine powers within a preset historical time period, the total engine power is determined; the current correction factor is multiplied by the total engine power to determine the corrected total engine power; based on the corrected total engine power, the current remaining regeneration time is determined from the target one-dimensional chart.

[0077] The technical solution of this invention obtains the engine model, current ignition efficiency, current air-fuel ratio, and current engine power of the target vehicle during the particulate filter regeneration process; determines the current correction factor based on the engine model, current ignition efficiency, and current air-fuel ratio; determines the current remaining regeneration time based on the engine model, current correction factor, and current engine power; and controls the particulate filter of the target vehicle to interrupt regeneration if the current remaining regeneration time meets the first regeneration interruption condition. This automatically determines whether to interrupt regeneration during the particulate filter regeneration process without manual intervention, improving the accuracy of particulate filter regeneration interruption, reducing damage to various components in the target vehicle during the regeneration process, ensuring both regeneration effectiveness and the service life of components in the target vehicle, thereby improving the safety of users in the target vehicle.
