Description

Technical Field

[0001] This application relates to the field of engine exhaust gas treatment technology, and in particular to a parking regeneration control method, system, medium and electronic equipment for an engine. Background Technology

[0002] To meet increasingly stringent emission standards, engines currently use DPF (Diesel Particulate Filter) devices to capture carbon particulate matter in exhaust. The process of removing the attached particles from the particulate filter is called regeneration. Parking regeneration is one type of regeneration method, which actively triggers the removal of carbon load from the particulate filter.

[0003] In related technologies, when the vehicle's operating conditions are not suitable for issuing a parking regeneration request, if there are regeneration requests much smaller than the parking regeneration interval, and the preset regeneration interval is not adjusted, it will result in the inability to issue a parking regeneration request. Consequently, the carbon load of the particulate filter will continue to increase, and if the carbon load exceeds the safety threshold, there is a risk of burnout, thereby reducing the safety factor of the particulate filter. Summary of the Invention

[0004] This application provides a parking regeneration control method, system, medium, and electronic device for an engine. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general description, nor is it intended to identify key / important components or describe the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0005] In a first aspect, embodiments of this application provide a parking regeneration control method for an engine, the method comprising:

[0006] Determine the total time elapsed between the current time of the operating vehicle and the last parking and regeneration time;

[0007] Calculate the carbon loading accumulation rate of the particulate filter when the total duration is greater than the preset regeneration time interval.

[0008] Based on the carbon loading accumulation rate, the preset regeneration time interval is adjusted to obtain the first regeneration time interval;

[0009] The first regeneration time interval is reset as the preset regeneration time interval, and the step of determining the total time from the current time of the running vehicle to the last parking regeneration time continues until the preset regeneration time interval is less than or equal to the preset minimum value, at which point the oxygen concentration of the vehicle's operating environment is determined.

[0010] The preset regeneration time interval, which is less than or equal to the preset minimum value, is corrected based on the oxygen concentration.

[0011] Based on the corrected preset regeneration time interval, the vehicle's engine is controlled to perform parking regeneration.

[0012] Optionally, determine the total time elapsed between the current time of the operating vehicle and the last parking regeneration time, including:

[0013] The total driving time of the vehicle is accumulated when the controller detects that the particulate filter is performing parking regeneration.

[0014] The total accumulated time is taken as the total time elapsed between the current time of the operating vehicle and the last time of parking and regeneration.

[0015] Optionally, the carbon loading accumulation rate of the particulate filter is calculated, including:

[0016] Obtain the carbon load accumulated on the particulate filter between the current time and the previous parking regeneration time;

[0017] Calculate the ratio between carbon loading and total duration;

[0018] The ratio is used as the carbon loading accumulation rate of the particulate filter.

[0019] Optionally, the preset regeneration time interval can be adjusted based on the carbon loading accumulation rate, including:

[0020] If the carbon loading accumulation rate exceeds a preset rate threshold, the preset regeneration time interval will be shortened by a preset duration; or,

[0021] If the carbon loading accumulation rate is less than a preset rate threshold, the preset regeneration time interval will be extended by a preset duration; or,

[0022] When the carbon load accumulation rate is equal to the preset rate threshold, the preset regeneration time interval is used as the parking regeneration time interval.

[0023] Optionally, determine the oxygen concentration of the vehicle's operating environment, including:

[0024] Determine whether the vehicle is currently in oxygen concentration monitoring mode;

[0025] When the vehicle is currently in oxygen concentration monitoring mode, oxygen concentration detection equipment is used to detect the oxygen concentration of the vehicle's operating environment.

[0026] Optionally, the method also includes:

[0027] If the vehicle is not currently under oxygen concentration monitoring conditions, determine whether oxygen concentration monitoring conditions should be activated in the current driving cycle.

[0028] If the oxygen concentration monitoring condition is not released in the current driving cycle, the number of times the monitoring is not released is automatically incremented by one, and the step of determining whether the oxygen concentration monitoring condition is released in the current driving cycle continues until the number of times the monitoring is not released exceeds the preset threshold. At this point, the vehicle's parking regeneration is triggered according to the preset minimum value, and the oxygen concentration in the current environment is detected during the cooling phase of the parking regeneration.

[0029] Optionally, the method also includes:

[0030] Adjust the vehicle's engine performance parameters based on the oxygen concentration.

[0031] Secondly, embodiments of this application provide a parking regeneration control system for an engine, the system comprising:

[0032] The total duration determination module is used to determine the total duration from the current time of the running vehicle to the last parking and regeneration time;

[0033] The carbon load accumulation rate calculation module is used to calculate the carbon load accumulation rate of the particulate filter when the total duration is greater than the preset regeneration time interval.

[0034] The first regeneration time interval correction module is used to correct the preset regeneration time interval according to the carbon loading accumulation rate to obtain the first regeneration time interval;

[0035] The oxygen concentration determination module is used to reset the first regeneration time interval as the preset regeneration time interval and continue to execute the step of determining the total time from the current time of the running vehicle to the last parking regeneration time until the preset regeneration time interval is less than or equal to the preset minimum value, and then determine the oxygen concentration of the vehicle's operating environment.

[0036] The second regeneration time interval correction module is used to correct the preset regeneration time interval that is less than or equal to the preset minimum value based on the oxygen concentration.

[0037] The parking regeneration control module is used to control the vehicle's engine to perform parking regeneration based on a modified preset regeneration time interval.

[0038] Thirdly, embodiments of this application provide a computer storage medium storing multiple instructions adapted for loading and execution of the above-described method steps by a processor.

[0039] Fourthly, embodiments of this application provide an electronic device that may include: a processor and a memory; wherein the memory stores a computer program adapted to be loaded by the processor and executed by the above-described method steps.

[0040] The technical solutions provided in this application embodiment may include the following beneficial effects:

[0041] In this embodiment, the engine's parking regeneration control system first calculates the carbon load accumulation rate when the total time elapsed between the current moment and the last parking regeneration moment is greater than a preset regeneration time interval. Then, based on the carbon load accumulation rate, the preset regeneration time interval is corrected to obtain a first regeneration time interval. Next, the first regeneration time interval is used again as the preset regeneration time interval, and the above steps continue until the preset regeneration time interval is less than or equal to a preset minimum value, at which point the oxygen concentration of the vehicle's operating environment is determined. Finally, based on the oxygen concentration, the preset regeneration time interval less than or equal to the preset minimum value is corrected, and based on the corrected preset regeneration time interval, the vehicle's engine is controlled to perform parking regeneration. Because this application dynamically adjusts the regeneration time interval through multi-level adjustments of the carbon load accumulation rate and oxygen concentration, it achieves self-adaptation of parking regeneration to operating conditions and the operating environment, preventing the particulate filter from burning out due to excessive carbon load, thereby improving the safety factor of the particulate filter.

[0052] This application provides a parking regeneration control method, system, medium, and electronic equipment for an engine to solve the problems existing in the aforementioned related technologies. In the technical solution provided by this application, because the regeneration time interval is dynamically adjusted in multiple levels by the carbon load accumulation rate and oxygen concentration, parking regeneration achieves self-adaptation to operating conditions and environment, preventing the particulate filter from burning out due to excessive carbon load, thereby improving the safety factor of the particulate filter. The following is a detailed description using exemplary embodiments.

[0053] The following will be combined with the appendix Figure 1 - Appendix Figure 2 This application provides a detailed description of the engine parking regeneration control method provided in its embodiments. This method can be implemented using a computer program and can run on a parking regeneration control system for an engine based on the von Neumann architecture. This computer program can be integrated into the application or run as a standalone utility application.

[0054] Please see Figure 1 This is a flowchart illustrating a parking regeneration control method for an engine, as provided in this application embodiment. Figure 1 As shown, the method in this application embodiment may include the following steps:

[0055] S101, determine the total time elapsed between the current time of the running vehicle and the last parking regeneration time;

[0056] Among them, the previous parking regeneration time is the time recorded when parking regeneration occurred before the current time, and parking regeneration occurring before the current time can be denoted as Z1.

[0057] In this embodiment, when the controller detects that the current driving cycle has completed parking regeneration Z1, it clears the accumulated parking regeneration time interval T1 and records the time of Z1, and restarts the timing starting from the time of Z1. The accumulated time can be stored in the controller.

[0058] Furthermore, during the timing process, when the controller detects that the current driving cycle has completed parking regeneration Z2, it indicates that the second parking regeneration has occurred at the current moment. At this time, the vehicle driving time accumulated in the controller is used as the total time from the current moment to the previous parking regeneration moment.

[0059] In one possible implementation, when the controller detects that the particle trap is performing parking regeneration, the total driving time of the vehicle is accumulated; the accumulated total time is used as the total time from the current time of the running vehicle to the last parking regeneration time.

[0060] S102, Calculate the carbon loading accumulation rate of the particulate filter when the total duration is greater than the preset regeneration time interval;

[0061] The preset regeneration time interval is the parking regeneration time interval set by the engineer for the particulate filter under standard operating conditions when the vehicle leaves the factory, for example, 900 hours.

[0062] In one possible implementation, when the total duration is greater than a preset regeneration time interval, the carbon load accumulation rate R of the particulate trap is calculated by the time interval T1 between two regenerations and the carbon load in the particulate trap between two regenerations.

[0063] Specifically, when calculating the carbon load accumulation rate of the particulate filter, the carbon load accumulated on the particulate filter between the current time and the previous parking regeneration time is first obtained; then the ratio between the carbon load and the total duration is calculated; finally, the ratio is used as the carbon load accumulation rate of the particulate filter.

[0064] S103, Based on the carbon loading accumulation rate, the preset regeneration time interval is corrected to obtain the first regeneration time interval;

[0065] In this embodiment of the application, when the preset regeneration time interval is adjusted according to the carbon load accumulation rate, if the carbon load accumulation rate is greater than the preset rate threshold, the preset regeneration time interval is shortened by a preset duration; or, if the carbon load accumulation rate is less than the preset rate threshold, the preset regeneration time interval is extended by a preset duration; or, if the carbon load accumulation rate is equal to the preset rate threshold, the preset regeneration time interval is used as the parking regeneration time interval.

[0066] The preset rate threshold can be set based on the historical carbon load accumulation data of the particulate filter, and there is no limitation here.

[0067] For example, when the carbon load accumulation rate R is greater than the threshold Rt, it is considered that the particulate filter accumulation rate of this vehicle is too high, and there is a risk of filter burnout at this parking regeneration interval. Therefore, the parking regeneration interval is reduced according to the carbon load accumulation rate R, and the reduced value is used as the latest parking regeneration interval.

[0068] For example, when the carbon load accumulation rate R is less than the threshold Rt, it is considered that the particulate filter accumulation rate of this vehicle is too slow. At this time, the parking regeneration interval will cause energy loss. Therefore, it is necessary to extend the parking regeneration interval and use the extended parking regeneration interval as the latest parking regeneration interval time.

[0069] S104, the first regeneration time interval is reset as the preset regeneration time interval, and the step of determining the total time from the current time of the running vehicle to the last parking regeneration time continues until the preset regeneration time interval is less than or equal to the preset minimum value, and the oxygen concentration of the vehicle's operating environment is determined.

[0070] In this embodiment, the first regeneration time interval is reset as the preset regeneration time interval, and the step of determining the total time elapsed between the current time of the operating vehicle and the previous parking regeneration time continues. This enables dynamic adjustment of the vehicle's parking regeneration time interval, allowing it to adapt to different operating conditions. If the preset regeneration time interval continues to decrease during the dynamic adjustment process until it is less than or equal to the preset minimum value, it is suspected that the vehicle's operating environment is harsh and the oxygen concentration is too low than normal. Therefore, oxygen concentration detection is required.

[0071] The preset minimum value is the driving time interval corresponding to the target oxygen concentration that is lower than the normal oxygen concentration value in harsh environments. This time interval can be set by the user based on different oxygen concentrations tested in actual harsh environment scenarios, and is not limited here.

[0072] In one possible implementation, it is first determined whether the vehicle is currently in oxygen concentration monitoring mode; then, if the vehicle is currently in oxygen concentration monitoring mode, oxygen concentration detection equipment is used to detect the oxygen concentration of the vehicle's operating environment. For example, if the accelerator pedal opening, brake pedal opening, vehicle speed, and engine temperature are all in oxygen concentration monitoring mode during this driving cycle, then the oxygen concentration in the current environment is detected by devices such as NOx sensors.

[0073] Furthermore, if the vehicle is not currently in oxygen concentration monitoring mode, the system first determines whether oxygen concentration monitoring has been activated in the current driving cycle. If oxygen concentration monitoring has not been activated in the current driving cycle, the count of unactivated monitoring is automatically incremented by one, and the process of determining whether oxygen concentration monitoring has been activated in the current driving cycle continues until the count exceeds a preset threshold. At this point, parking regeneration is triggered based on a preset minimum value, and the oxygen concentration in the current environment is detected during the cooling phase of parking regeneration. For example, if the vehicle is not in oxygen concentration monitoring mode during operation, the count N of unactivated monitoring is incremented by one per driving cycle. This continues until the accumulated count N > the threshold Nt. The parking regeneration time interval is then adjusted to Tn (a smaller value), and parking regeneration is triggered as quickly as possible using this value, with the oxygen concentration in the current environment detected during the cooling phase of parking regeneration.

[0074] The preset threshold number is a value set for the number of times parking regeneration can be actively triggered when the vehicle is not in oxygen concentration monitoring mode. The preferred value is 5 times. When the vehicle is not in oxygen concentration monitoring mode after accumulating 5 times, parking regeneration can be actively triggered.

[0075] S105, based on the oxygen concentration, correct the preset regeneration time interval which is less than or equal to the preset minimum value.

[0076] In this embodiment, after determining the oxygen concentration in the current vehicle's operating environment, a preset regeneration time interval less than or equal to a preset minimum value can be precisely corrected, and the vehicle's engine performance parameters can be adjusted according to the oxygen concentration. Ultimately, the vehicle can operate based on the corrected engine operating parameters to adapt to the current oxygen concentration environment, and the engine can be controlled to perform parking regeneration according to the corrected parking regeneration time interval.

[0077] For example Figure 2 As shown, Figure 2This is a schematic block diagram of the engine parking regeneration control process provided in this application. First, it is determined whether the vehicle has completed the first parking regeneration N1. If not, the system waits for the vehicle to complete the first parking regeneration. If it has, the vehicle's driving time T1 is accumulated based on the time of the first parking regeneration and stored in the controller. If the vehicle's driving time T1 is greater than the preset parking regeneration time interval Tt, it indicates that the second parking regeneration has been completed. Then, the carbon load accumulation rate needs to be calculated based on the driving time T1 of the two parking regenerations and the carbon load during the two parking regenerations. If the carbon load accumulation rate is greater than or less than a preset threshold, the regeneration time interval needs to be expanded or reduced to T2 based on the accumulation rate and stored in the controller EE. The above operation continues. If the regeneration time interval T2 keeps decreasing until it is less than or equal to the preset minimum value, it is determined whether the current vehicle operating environment is in an oxygen concentration monitoring condition. If so, the oxygen concentration Co in the current environment is detected. If not, the number of monitoring cycles N that have not been released is incremented by 1 per driving cycle. Until the cumulative number of times N > threshold Nt, the parking regeneration time interval is adjusted to Tn (a smaller value), and parking regeneration is triggered as soon as possible using this value; the oxygen concentration Co in the current environment is detected through the cooling stage of parking regeneration; after obtaining the oxygen concentration in the current environment, the parking regeneration time interval can be adjusted to T3 according to the current oxygen concentration, and the engine performance parameters can be adjusted according to the ambient oxygen concentration to control the engine operation based on the adjusted parameters.

[0078] It should be noted that this application is based on the sequential modification of the parking regeneration time interval to achieve step-by-step protection of the particulate filter, preventing the filter from burning out due to excessive carbon load, and at the same time preventing fuel waste due to excessively short regeneration time intervals.

[0079] S106, based on the corrected preset regeneration time interval, controls the vehicle's engine to perform parking regeneration.

[0080] In this embodiment of the application, after obtaining the corrected preset regeneration time interval based on step S103 or step S105, the vehicle's engine can be controlled to perform parking regeneration based on the corrected preset regeneration time interval obtained in step S103 or step S105.

[0081] It should be noted that when controlling the vehicle's engine to perform parking regeneration based on the corrected preset regeneration time interval obtained in step S103, if the preset regeneration time interval is greater than the preset minimum value, the vehicle's engine will continue to be controlled to perform parking regeneration based on the corrected preset regeneration time interval obtained in step S103. If the preset regeneration time interval is less than or equal to the preset minimum value, the vehicle's engine will be controlled to perform parking regeneration based on the corrected preset regeneration time interval obtained in step S105.

[0082] In this embodiment, the engine's parking regeneration control system first calculates the carbon load accumulation rate when the total time elapsed between the current moment and the previous parking regeneration moment is greater than a preset regeneration time interval. Then, based on the carbon load accumulation rate, the preset regeneration time interval is corrected to obtain a first regeneration time interval. Next, the first regeneration time interval is used again as the preset regeneration time interval, and the above steps continue until the preset regeneration time interval is less than or equal to a preset minimum value, at which point the oxygen concentration of the vehicle's operating environment is determined. Finally, based on the oxygen concentration, the preset regeneration time interval that is less than or equal to the preset minimum value is corrected. Because this application dynamically adjusts the regeneration time interval through multiple levels of carbon load accumulation rate and oxygen concentration, it achieves self-adaptation of parking regeneration to operating conditions and the operating environment, preventing the particulate filter from burning out due to excessive carbon load, thereby improving the safety factor of the particulate filter.

[0107] The preset regeneration time interval, which is less than or equal to the preset minimum value, is corrected based on the oxygen concentration.

[0108] Based on the corrected preset regeneration time interval, the vehicle's engine is controlled to perform parking regeneration.

[0109] In one embodiment, when the processor 1001 determines the total time elapsed between the current moment of the running vehicle and the last parking regeneration moment, it specifically performs the following operations:

[0110] The total driving time of the vehicle is accumulated when the controller detects that the particulate filter is performing parking regeneration.

[0111] The total accumulated time is taken as the total time elapsed between the current time of the operating vehicle and the last time of parking and regeneration.

[0117] If the carbon loading accumulation rate exceeds a preset rate threshold, the preset regeneration time interval will be shortened by a preset duration; or,

[0118] If the carbon loading accumulation rate is less than a preset rate threshold, the preset regeneration time interval will be extended by a preset duration; or,

[0119] When the carbon load accumulation rate is equal to the preset rate threshold, the preset regeneration time interval is used as the parking regeneration time interval.

[0124] If the vehicle is not currently under oxygen concentration monitoring conditions, determine whether oxygen concentration monitoring conditions should be activated in the current driving cycle.

[0125] If the oxygen concentration monitoring condition is not released in the current driving cycle, the number of times the monitoring is not released is automatically incremented by one, and the step of determining whether the oxygen concentration monitoring condition is released in the current driving cycle continues until the number of times the monitoring is not released exceeds the preset threshold. At this point, the vehicle's parking regeneration is triggered according to the preset minimum value, and the oxygen concentration in the current environment is detected during the cooling phase of the parking regeneration.

[0126] In one embodiment, the processor 1001 also performs the following operations:

[0127] Adjust the vehicle's engine performance parameters based on the oxygen concentration.

[0128] In this embodiment, the engine's parking regeneration control system first calculates the carbon load accumulation rate when the total time elapsed between the current moment and the previous parking regeneration moment is greater than a preset regeneration time interval. Then, based on the carbon load accumulation rate, the preset regeneration time interval is corrected to obtain a first regeneration time interval. Next, the first regeneration time interval is used again as the preset regeneration time interval, and the above steps continue until the preset regeneration time interval is less than or equal to a preset minimum value, at which point the oxygen concentration of the vehicle's operating environment is determined. Finally, based on the oxygen concentration, the preset regeneration time interval less than or equal to the preset minimum value is corrected, and based on the corrected preset regeneration time interval, the vehicle's engine is controlled to perform parking regeneration. Because this application dynamically adjusts the regeneration time interval through multiple levels of carbon load accumulation rate and oxygen concentration, it achieves self-adaptation of parking regeneration to operating conditions and the operating environment, preventing the particulate filter from burning out due to excessive carbon load, thereby improving the safety factor of the particulate filter.

The engine parking regeneration control program can be stored in a computer-readable storage medium. When executed, the program can include the processes of the embodiments of the above methods.
