Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle intelligent control, and in particular to a particulate filter regeneration control method, an electronic device and a vehicle. BACKGROUND

[0002] The particulate filter is used to capture soot particles in diesel engine exhaust gas and reduce particulate matter emissions. As the vehicle mileage increases, more and more soot particles will be deposited in the particulate filter, causing the particulate filter to be blocked. Therefore, when the soot particles accumulate to a certain extent in the particulate filter, they must be burned off through a regeneration process. Conventional regeneration methods have some shortcomings, especially for users who often drive short distances and do not want to manually regenerate when parked. Regeneration is often interrupted, and long-term unsuccessful regeneration can cause engine failure. SUMMARY

[0003] Therefore, the purpose of the present application is to provide a particulate filter regeneration control method, an electronic device and a vehicle to improve the success rate of particulate filter regeneration and prevent frequent regeneration failure from causing engine failure.

[0004] To achieve the above purpose, the present application provides a particulate filter regeneration control method, comprising:

[0005] obtaining a historical number of parked regeneration times of the particulate filter;

[0006] in response to determining that the historical number of parked regeneration times is greater than or equal to a preset number of parked regeneration times, correcting a preset default soot loading threshold to obtain a target soot loading threshold, and performing regeneration control according to the target soot loading threshold and a real-time soot loading of the particulate filter, and determining a regeneration control result;

[0007] determining whether the particulate filter meets a forced regeneration condition based on the regeneration control result;

[0008] in response to determining that the particulate filter meets the forced regeneration condition, performing a forced regeneration strategy for the particulate filter.

[0009] Further, the regeneration control according to the target soot loading threshold and the real-time soot loading of the particulate filter comprises:

[0010] in response to determining that the real-time soot loading is greater than or equal to the target soot loading threshold, obtaining vehicle driving information, and determining whether the particulate filter meets a driving regeneration condition according to the vehicle driving information;

[0011] in response to determining that the particulate filter meets the driving regeneration condition, regenerating the particulate filter.

[0012] Since the real-time carbon load is greater than or equal to the target carbon load threshold, it indicates that the amount of soot particles accumulated in the particulate filter is already high. If the particulate filter meets the driving regeneration condition at this time, the particulate filter is regenerated, which can prevent too many soot particles from accumulating and reduce the risk of the particulate filter being blocked, thereby improving the running efficiency and reliability of the vehicle and improving the driving experience of the user.

[0013] Further, the vehicle driving information includes engine speed, vehicle speed, and running time length of automatic cruise; and the determining whether the particulate filter meets the driving regeneration condition according to the vehicle driving information comprises:

[0014] In response to determining that the engine speed is greater than or equal to a preset speed and the vehicle speed is greater than or equal to a preset vehicle speed, it is determined that the particulate filter meets the driving regeneration condition; or,

[0015] In response to determining that the engine speed is greater than or equal to a preset speed and the running time length is greater than or equal to a preset running time length, it is determined that the particulate filter meets the driving regeneration condition.

[0016] When the engine speed and the vehicle speed both meet the driving regeneration condition of the particulate filter, it indicates that the vehicle is in an efficient running state, the exhaust temperature is high, and the driving condition is good, which is conducive to the combustion and removal of soot particles in the particulate filter. By ensuring that the vehicle is in a running state for a long time before determining that the particulate filter meets the driving regeneration condition, it can ensure that the regeneration process has enough time to proceed, reduce the risk of the regeneration being interrupted, and improve the success rate of regeneration.

[0017] Further, the regenerating the particulate filter comprises:

[0018] determining a regeneration time of a historical single driving regeneration, and determining a driving regeneration time less than the regeneration time;

[0019] regenerating the particulate filter based on the driving regeneration time.

[0020] Since a shorter regeneration time reduces the interruption conditions that may be encountered during the regeneration process, such as stopping, decelerating, or other changes in the driving state, determining a driving regeneration time less than the regeneration time and regenerating the particulate filter based on the driving regeneration time can ensure that the regeneration process proceeds smoothly. If the soot particles in the particulate filter cannot be completely removed within the shorter driving regeneration time, the regeneration can continue in the next driving process that meets the driving regeneration condition. The phased regeneration ensures that the soot particles in the particulate filter can be completely removed eventually. Multiple shorter-time regeneration operations have a cumulative effect equivalent to one long-time regeneration, but are easier to complete in actual driving processes, thereby improving the overall success rate of regeneration.

[0021] Further, the regeneration control result comprises a success number of successful regenerations and a failure number of failed regenerations; and the determining whether the particulate filter meets the forced regeneration condition based on the regeneration control result comprises:

[0022] in response to determining that the real-time carbon load is less than the calibrated carbon load threshold, determining that the forced regeneration condition is not met;

[0023] in response to determining that the real-time carbon load is greater than or equal to the calibrated carbon load threshold, determining the success number of successful regenerations and the failure number of failed regenerations;

[0024] determining a regeneration success rate according to the success number and the failure number;

[0025] in response to determining that the regeneration success rate is less than or equal to a preset success rate, determining that the forced regeneration condition is met;

[0026] in response to determining that the regeneration success rate is greater than the preset success rate, determining that the forced regeneration condition is not met.

[0027] By determining a regeneration success rate according to the success number of successful regenerations and the failure number of failed regenerations, if it is determined that the regeneration success rate is less than or equal to a preset success rate, it indicates that the current regeneration strategy fails to effectively remove the soot particles in the particulate filter, which is usually caused by the interruption of the driving regeneration process. At this time, it is determined that the forced regeneration condition is met, and the forced regeneration strategy for the particulate filter is executed to ensure that the soot particles in the particulate filter are effectively removed. Not only does this ensure that the soot particles in the particulate filter are completely removed, preventing the particulate filter from being clogged and the engine from malfunctioning, but it also improves the operating efficiency and reliability of the vehicle.

[0028] Further, the method further comprises:

[0029] in response to determining that the success number is greater than or equal to a preset number, resetting the historical number of parked regenerations to zero.

[0030] When the success number is greater than or equal to a preset number, it indicates that the regeneration process is successful multiple times, and at the same time, it indicates that the vehicle has good driving conditions in the recent period of time. Therefore, the historical number of parked regenerations is reset to zero, and the vehicle normally executes the driving regeneration strategy, thereby optimizing the regeneration frequency and timing and improving the user driving experience.

[0031] Further, the executing the forced regeneration strategy for the particulate filter comprises:

[0032] in response to determining that the vehicle is in a parked state and the engine is in an idle state, controlling the single injection amount and the injection frequency of fuel injected into the cylinder according to the temperature required for the regeneration of the particulate filter, and prohibiting other operations on the vehicle except for exiting the forced regeneration strategy;

[0033] In response to determining that the particulate trap regeneration is completed, exiting the forced regeneration strategy.

[0034] During the forced regeneration, other operations of the vehicle are prohibited except for exiting the regeneration strategy, ensuring that the engine and exhaust system are operated in a stable working condition to provide continuous high-temperature exhaust gas, thereby ensuring the smooth progress of the regeneration process and avoiding the risk of interrupted regeneration process, thereby avoiding the diesel engine oil dilution and engine failure caused by frequent regeneration failure.

[0035] Further, before the obtaining the historical number of parked regeneration of the particulate trap, comprising:

[0036] Obtaining the detected carbon load of the particulate trap;

[0037] In response to determining that the detected carbon load is greater than or equal to the default carbon load threshold, determining to perform on-road regeneration on the particulate trap;

[0038] In response to determining that the detected carbon load is greater than or equal to the calibrated carbon load threshold, determining to perform parked regeneration on the particulate trap; the calibrated carbon load threshold is greater than the default carbon load threshold.

[0039] After obtaining the detected carbon load of the particulate trap, performing on-road regeneration or parked regeneration according to the default carbon load threshold and the calibrated carbon load threshold, so that the soot particles are effectively removed, thereby ensuring the normal operation of the particulate trap and preventing the particulate trap from being blocked and the engine from failing.

[0040] Based on the same inventive concept, the application also provides an electronic device, comprising a memory, a processor and a computer program stored in the memory and executable by the processor, wherein the processor implements the method as described above when executing the computer program.

[0041] Based on the same inventive concept, the application also provides a vehicle, comprising the electronic device as described above.

[0042] From the above, the particle trap regeneration control method, electronic device and vehicle provided by the application can be seen, wherein the method comprises: acquiring a historical parked regeneration number of the particle trap; in response to determining that the historical parked regeneration number is greater than or equal to a preset parked regeneration number, correcting a preset default carbon load threshold to obtain a target carbon load threshold, and performing regeneration control according to the target carbon load threshold and a real-time carbon load of the particle trap, and determining a regeneration control result; the regeneration process is triggered when the soot particles accumulate to a lower level, preventing the soot particles from accumulating to a too high level and reducing the risk of particle trap blockage; judging whether the particle trap meets a forced regeneration condition based on the regeneration control result; in response to determining that the particle trap meets the forced regeneration condition, performing a forced regeneration strategy for the particle trap. The regeneration process is prevented from being interrupted, ensuring the success of the regeneration process, avoiding diesel engine oil dilution and engine failure caused by frequent regeneration, and improving the reliability and durability of the engine.

[0048] In order to make the purpose, technical solutions and advantages of the application more clear, the application will be further described in detail below in combination with specific embodiments and with reference to the drawings.

[0050] In the prior art, the particulate filter (PFT) is a key component in diesel engine emission control systems. Its primary function is to capture soot particles from diesel engine exhaust, reducing particulate matter emissions and meeting increasingly stringent emission regulations. As vehicle mileage increases, more and more soot particles accumulate in the PFT, causing PFT blockage. This increases vehicle exhaust backpressure, resulting in poor exhaust flow, reduced power, increased fuel consumption, and even engine failure. Therefore, when soot particles accumulate to a certain level in the PFT, they must be burned through a regeneration process to prevent the PFT from clogging or burning due to excessive carbon deposits. Conventional PFT regeneration methods primarily include driving regeneration mode and parked regeneration mode. When the vehicle's operating conditions meet the PFT's driving regeneration requirements, the vehicle automatically initiates active PFT regeneration without user intervention. However, when the vehicle's operating conditions do not meet the driving regeneration requirements, the user is prompted to manually initiate active PFT regeneration, known as parked regeneration, while the vehicle is idling. However, this conventional regeneration method has some shortcomings, especially for users who often drive short distances and are unwilling to regenerate manually when parking. Driving regeneration is often interrupted, manual parking regeneration takes a long time, and parking regeneration is also easily interrupted. Failure to regenerate successfully for a long time may cause engine failure.

[0051] Based on the above problems, the applicant finds that: obtaining the historical number of parked regeneration of the particulate filter; in response to determining that the historical number of parked regeneration is greater than or equal to a preset number of parked regeneration, modifying a preset default carbon load threshold to obtain a target carbon load threshold, and performing regeneration control according to the target carbon load threshold and the real-time carbon load of the particulate filter, and determining the regeneration control result; judging whether the particulate filter meets the forced regeneration condition based on the regeneration control result; in response to determining that the particulate filter meets the forced regeneration condition, executing the forced regeneration strategy for the particulate filter. To improve the regeneration success rate of the particulate filter during vehicle driving and under idling conditions, to prevent frequent regeneration failure from causing diesel engine oil dilution and engine failure, to improve the reliability and durability of the engine, and to improve the driving experience of the user.

[0052] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] The present application provides a particulate filter regeneration control method, as shown in some embodiments, the method is executed by a vehicle controller or a data processor set independently of the vehicle controller, and subsequent embodiments are all exemplarily illustrated by taking the vehicle controller as an example; the method comprises: Figure 1

[0054] S101, obtaining the historical number of parked regeneration of the particulate filter;

[0055] In specific implementation, the electronic control unit of the vehicle will monitor and record the regeneration condition of the particulate filter in real time, including the type of each regeneration (on-road regeneration or parked regeneration), the start time and end time of the regeneration, and whether the regeneration is successful or not. Parked regeneration refers to the particulate filter regeneration process performed by the vehicle in a stationary state. It is usually started when the vehicle is idling, and the engine burns and removes the soot particles in the particulate filter through specific operations (such as increasing the exhaust temperature). The trigger of parked regeneration is usually due to the fact that the vehicle fails to meet the conditions for on-road regeneration during driving, or on-road regeneration is interrupted many times, resulting in a high level of carbon load in the particulate filter, which needs to be removed through parked regeneration. Understanding the historical number of parked regeneration helps to evaluate the use of the vehicle and the regeneration efficiency of the particulate filter. If the number of parked regeneration is too high, it may indicate that the driving conditions of the vehicle are not conducive to the on-road regeneration, or the regeneration efficiency of the particulate filter is low. Therefore, the historical number of parked regeneration of the particulate filter is obtained, and data support is provided for the optimization of the regeneration strategy of the particulate filter based on the historical number of parked regeneration.

[0056] ​S102, in response to determining that the historical parked regeneration number is greater than or equal to the preset parked regeneration number, correcting a preset default carbon load threshold to obtain a target carbon load threshold, and performing regeneration control according to the target carbon load threshold and the real-time carbon load of the particulate filter, and determining a regeneration control result;

[0057] In specific implementation, when it is determined that the historical parked regeneration number is greater than or equal to the preset parked regeneration number (for example, the preset parked regeneration number can be set to 2), the preset default carbon load threshold is corrected. The default carbon load threshold is a threshold for determining whether to perform on-road regeneration when the vehicle is normally judged. That is, when the detected carbon load is greater than or equal to the default carbon load threshold (for example, the default carbon load threshold can be set to 18g), it is determined to perform on-road regeneration on the particulate filter. However, when it is determined that the historical parked regeneration number is greater than or equal to the preset parked regeneration number, the preset default carbon load threshold is corrected to obtain a target carbon load threshold, that is, the default carbon load threshold is reduced to obtain the target carbon load threshold (for example, the target carbon load threshold can be set to 80% of the default carbon load threshold). Since the target carbon load threshold is less than the default carbon load threshold, when the regeneration control is performed according to the target carbon load threshold and the real-time carbon load of the particulate filter, the sensitivity of triggering the regeneration of the particulate filter can be improved, so that the regeneration process is triggered when the carbon soot particles accumulate to a lower level. At the same time, the time of a single regeneration can be reduced, and the success rate of regeneration can be improved. After the regeneration control is performed according to the target carbon load threshold and the real-time carbon load of the particulate filter (the real-time carbon load is measured in real time by a differential pressure sensor and other monitoring devices), the regeneration control result needs to be determined. The regeneration control result includes the number of successful regeneration and the number of failed regeneration, etc. The regeneration control result can provide a reliable basis for subsequent regeneration strategy.

[0058] S103, determining whether the particulate filter meets a forced regeneration condition based on the regeneration control result;

[0059] In specific implementation, the regeneration control result includes the number of successful regeneration and the number of failed regeneration, etc. Based on the regeneration control result, it is determined whether the particulate filter meets the forced regeneration condition. The regeneration process of the particulate filter can be effectively managed, and the particulate filter can be cleaned in time under the condition of high carbon load. Engine failure caused by blockage of the particulate filter can be prevented, and the reliability and durability of the vehicle can be improved.

[0060] S104, in response to determining that the particulate filter meets the forced regeneration condition, performing a forced regeneration strategy for the particulate filter.

[0061] In a specific implementation, when it is determined that the particulate filter meets the forced regeneration condition, a forced regeneration strategy for the particulate filter is performed, that is, when the vehicle is in a parking state and the engine is in an idle state, the single injection amount and injection frequency of fuel injected into the cylinder are controlled according to the temperature required for regeneration of the particulate filter, and other operations of the vehicle are prohibited except for exiting the forced regeneration strategy, to prevent the regeneration process from being interrupted, ensure that the particulate filter is regenerated successfully at one time, and avoid diesel engine oil dilution and engine failure caused by frequent regeneration.

[0062] In the embodiment, when the historical parking regeneration times are greater than or equal to the preset parking regeneration times, the target carbon loading threshold is obtained by reducing the default carbon loading threshold, the regeneration process is triggered when the soot particles accumulate to a lower level, the soot particles are prevented from accumulating to a high level, and the risk of particulate filter plugging is reduced. When it is determined that the particulate filter meets the forced regeneration condition, the forced regeneration strategy is performed, the regeneration process is prevented from being interrupted, the success of the regeneration process is ensured, diesel engine oil dilution and engine failure caused by frequent regeneration are avoided, and the reliability and durability of the engine are improved.

[0063] In some embodiments, as shown in FIG. 1, the regeneration control according to the target carbon loading threshold and the real-time carbon loading of the particulate filter includes: Figure 2

[0064] S201, in response to determining that the real-time carbon loading is greater than or equal to the target carbon loading threshold, obtaining vehicle driving information, and determining whether the particulate filter meets a driving regeneration condition according to the vehicle driving information;

[0065] In a specific implementation, the real-time carbon loading refers to the amount of soot particles currently accumulated in the particulate filter, which can be monitored in real time by a differential pressure sensor or the like. When the real-time carbon loading is greater than or equal to the target carbon loading threshold, it indicates that the amount of soot particles accumulated in the particulate filter is already high, and regeneration is needed. At this time, vehicle driving information is obtained, and whether the particulate filter meets a driving regeneration condition is determined according to the vehicle driving information. The vehicle driving information includes, but is not limited to, engine speed, vehicle speed, and automatic cruise running time; whether the particulate filter meets the driving regeneration condition is determined by the engine speed, vehicle speed, and automatic cruise running time. Since the target carbon loading threshold is less than the default carbon loading threshold, when the regeneration control is performed according to the target carbon loading threshold and the real-time carbon loading of the particulate filter, the sensitivity of triggering the particulate filter regeneration can be improved, so that the regeneration process is triggered when the soot particles accumulate to a lower level, and the accumulation of too many soot particles is avoided.

[0066] S202, in response to determining that the particulate filter meets the driving regeneration condition, the particulate filter is regenerated.

[0067] ​In particular, when it is determined that the particulate filter meets the driving regeneration condition, the particulate filter is regenerated. The driving regeneration refers to a process of burning and removing the soot particles in the particulate filter by controlling the operation of the engine to increase the exhaust temperature during the driving of the vehicle. The specific operation usually includes: increasing the fuel injection amount or adjusting the injection timing to increase the exhaust temperature, controlling the operating parameters of the engine to make the exhaust temperature reach the temperature required for the regeneration of the particulate filter, and under the action of high temperature, the soot particles react with oxygen to generate carbon dioxide, which is discharged with the exhaust gas, and the regeneration is completed.

[0068] In this embodiment, since the target carbon load threshold is less than the default carbon load threshold, the regeneration process can be triggered when the soot particles accumulate to a lower level. By triggering the regeneration in advance, the accumulation of soot particles is prevented, the risk of clogging of the particulate filter is reduced, the operating efficiency and reliability of the vehicle are improved, and the driving experience of the user is also improved.

[0069] In some embodiments, the vehicle driving information includes the engine speed, the vehicle speed, and the operating time length of the automatic cruise; and the determination of whether the particulate filter meets the driving regeneration condition according to the vehicle driving information includes:

[0070] In response to determining that the engine speed is greater than or equal to a preset speed and the vehicle speed is greater than or equal to a preset vehicle speed, it is determined that the particulate filter meets the driving regeneration condition.

[0071] In particular, when it is determined that the engine speed is greater than or equal to a preset speed (for example, the preset speed can be set to 750 r / min) and the vehicle speed is greater than or equal to a preset vehicle speed (for example, the preset vehicle speed can be set to 60 Km / h), it is determined that the particulate filter meets the driving regeneration condition. Generally, the engine speed greater than or equal to the preset speed is accompanied by a higher exhaust temperature, which is beneficial to the regeneration of the particulate filter, and the vehicle speed greater than or equal to the preset speed indicates that the current driving condition of the vehicle is good, and there is a high probability that the vehicle needs to be driven for a long time, which provides sufficient time for driving regeneration, and it can be determined that the particulate filter meets the driving regeneration condition.

[0072] In response to determining that the engine speed is greater than or equal to a preset speed and the operating time length is greater than or equal to a preset operating time length, it is determined that the particulate filter meets the driving regeneration condition.

[0073] In specific implementation, when it is determined that the engine speed is greater than or equal to a preset speed (for example, the preset speed can be set to 750 r / min) and the running duration is greater than or equal to a preset running duration (for example, the preset running duration can be set to 1 min), it is determined that the particulate filter meets the driving regeneration condition. Generally, when the engine speed is greater than or equal to the preset speed, the exhaust temperature is high, which is conducive to the regeneration of the particulate filter. When the running duration of the automatic cruise is greater than or equal to the preset running duration, it indicates that the current driving condition of the vehicle is good, and the vehicle is probably in a state of long-time driving. Therefore, sufficient time is provided for driving regeneration, and it can be determined that the particulate filter meets the driving regeneration condition. The success rate of regeneration is improved, so as to effectively remove the soot particles in the particulate filter, prevent the particulate filter from being blocked and the engine from failing, and also reduce the number of parking regeneration, improve the operation efficiency of the vehicle and the driving experience of the user.

[0074] In the embodiment, when the engine speed and the vehicle speed both meet the preset conditions, the vehicle is in an efficient operation state, the exhaust temperature is high, and the driving condition is good, which is conducive to the combustion and removal of soot particles in the particulate filter. By ensuring the running duration of the automatic cruise, it can be ensured that the regeneration process has sufficient time, the risk of interruption of regeneration is reduced, and the success rate of regeneration is improved.

[0075] In some embodiments, the regeneration of the particulate filter comprises:

[0076] determining a regeneration time of a historical single driving regeneration, and determining a driving regeneration time less than the regeneration time of the historical single driving regeneration;

[0077] In specific implementation, the historical single driving regeneration time refers to the time required to complete a regeneration in the past driving regeneration process. The historical single driving regeneration time can be the average value or the median of the historical regeneration time. Based on the historical single driving regeneration time, a shorter driving regeneration time is determined, that is, the driving regeneration time is less than the regeneration time of the historical single driving regeneration. For example, if the regeneration time of the historical single driving regeneration is 22 minutes, 15 minutes can be set as the driving regeneration time.

[0078] regenerating the particulate filter based on the driving regeneration time.

[0079] In the implementation, the particulate filter is regenerated based on the driving regeneration time, and the driving regeneration time is less than the regeneration time of the historical single driving regeneration, so that the success rate of single regeneration can be improved, and the regeneration is not interrupted, and the target carbon loading threshold is less than the default carbon loading threshold, so that the regeneration control is performed according to the target carbon loading threshold and the real-time carbon loading of the particulate filter, the sensitivity of triggering the regeneration of the particulate filter is improved, and the regeneration process is triggered when the soot particles accumulate to a low level, so that if the soot particles in the particulate filter cannot be completely removed within the driving regeneration time, the regeneration can be continued in the next driving process that meets the driving regeneration condition, so that the soot particles in the particulate filter can be completely removed.

[0080] In the embodiment, the short regeneration time reduces the interruption conditions that can be encountered in the regeneration process, such as parking, deceleration or other changes in driving state, and ensures the smooth progress of the regeneration process. Because the target carbon loading threshold is less than the default carbon loading threshold, the regeneration process can be triggered when the soot particles accumulate to a low level, and the sensitivity of triggering the regeneration is improved. By triggering the regeneration when the carbon loading is low, the accumulated carbon is processed in advance, the accumulation of soot particles is prevented, and the risk of clogging of the particulate filter is reduced. If the soot particles in the particulate filter cannot be completely removed within the short driving regeneration time, the regeneration can be continued in the next driving process that meets the driving regeneration condition. The phased regeneration ensures that the soot particles in the particulate filter can be completely removed. The cumulative effect of multiple short-time regeneration operations is equivalent to a long-time regeneration, but the regeneration is more likely to be completed in actual driving process, and the overall success rate of the regeneration is improved.

[0081] In some embodiments, the regeneration control result includes a success number of successful regeneration and a failure number of failed regeneration; and the determining whether the particulate filter meets the forced regeneration condition based on the regeneration control result includes:

[0082] determining that the forced regeneration condition is not met in response to determining that the real-time carbon loading is less than the calibrated carbon loading threshold;

[0083] In the implementation, the real-time carbon loading refers to the amount of soot particles currently accumulated in the particulate filter, which can be monitored in real time by a differential pressure sensor or the like. The calibrated carbon loading threshold is greater than the default carbon loading threshold (for example, the calibrated carbon loading threshold can be set to 120% of the default carbon loading threshold), and is used to determine whether the accumulation amount of soot particles in the particulate filter reaches a degree requiring forced regeneration. If it is determined that the real-time carbon loading is less than the calibrated carbon loading threshold, it indicates that the accumulation amount of soot particles in the particulate filter does not reach the degree requiring forced regeneration, and it is determined that the forced regeneration condition is not met.

[0084] determining a success number of successful regenerations and a failure number of failed regenerations in response to determining that the real-time carbon loading is greater than or equal to the calibrated carbon loading threshold;

[0085] In specific implementation, if it is determined that the real-time carbon loading is greater than or equal to the calibrated carbon loading threshold, it indicates that the amount of accumulated soot particles in the particulate filter is relatively large, and the success number of successful regenerations and the failure number of failed regenerations are determined. The success number of successful regenerations refers to the number of times of successfully removing soot particles in the particulate filter in the past driving regeneration processes, and the failure number of failed regenerations refers to the number of times of failing to effectively remove soot particles in the particulate filter in the past driving regeneration processes.

[0086] determining a success rate of regeneration according to the success number and the failure number;

[0087] In specific implementation, the success rate of regeneration is calculated according to the success number of successful regenerations and the failure number of failed regenerations. The calculation formula of the success rate of regeneration is as follows: success rate of regeneration = success number of successful regenerations / (success number of successful regenerations + failure number of failed regenerations) * 100%.

[0088] determining that the forced regeneration condition is met in response to determining that the success rate of regeneration is less than or equal to a preset success rate;

[0089] In specific implementation, if it is determined that the success rate of regeneration is less than or equal to a preset success rate (for example, the preset success rate can be set to 60%), it indicates that the current regeneration strategy fails to effectively remove soot particles in the particulate filter, which is usually caused by interruption of the driving regeneration process. At this time, it is determined that the forced regeneration condition is met, and the forced regeneration strategy for the particulate filter is executed to ensure that soot particles in the particulate filter are effectively removed. Not only is it ensured that soot particles in the particulate filter are thoroughly removed to prevent the particulate filter from being blocked and the engine from malfunctioning, but also the running efficiency and reliability of the vehicle are improved.

[0090] determining that the forced regeneration condition is not met in response to determining that the success rate of regeneration is greater than the preset success rate.

[0091] In specific implementation, if the success rate of regeneration is greater than the preset success rate, it indicates that the current driving regeneration strategy can effectively remove soot particles in the particulate filter, which is sufficient to maintain the normal operation of the particulate filter, and no additional forced regeneration strategy needs to be executed. Therefore, it is determined that the forced regeneration condition is not met, unnecessary forced regeneration operation is avoided, and interference with vehicle operation is reduced.

[0092] In this embodiment, the effectiveness of the current regeneration strategy can be evaluated by calculating the regeneration success rate. The regeneration success rate is calculated based on the number of successful and failed regenerations, providing an objective evaluation index. If the regeneration success rate is lower than the preset success rate, forced regeneration is triggered to ensure that the soot particles are completely removed.

[0093] In some embodiments, the method further comprises:

[0094] In response to determining that the number of successes is greater than or equal to the preset number of times, resetting the historical number of parked regenerations to zero.

[0095] In specific implementation, when the number of successes is greater than or equal to the preset number of times (for example, the preset number of times can be set to 20 times), it indicates that the regeneration process is successful multiple times, i.e., the strategy of regenerating the particulate filter when the particulate filter meets the driving regeneration condition is successfully executed multiple times, and it also indicates that the vehicle has good driving conditions in the recent period of time. Therefore, the historical number of parked regenerations is reset to zero, and the vehicle normally executes the driving regeneration strategy, i.e., in response to determining that the carbon load detected is greater than or equal to the default carbon load threshold, it is determined to perform driving regeneration on the particulate filter.

[0096] In this embodiment, by resetting the historical number of parked regenerations to zero when the number of successful regenerations reaches or exceeds the preset number of times, the regeneration strategy can be dynamically adjusted, the regeneration frequency and timing can be optimized, the user driving experience can be improved, the engine and the particulate filter can be protected, the fuel economy can be optimized, and the basis for data support and strategy optimization can be provided. Not only does it ensure that the soot particles in the particulate filter are effectively removed, preventing the particulate filter from being clogged and the engine from malfunctioning, but it also improves the operating efficiency and reliability of the vehicle.

[0097] In some embodiments, the execution of the forced regeneration strategy for the particulate filter comprises:

[0098] In response to determining that the vehicle is in a parked state and the engine is in an idle state, controlling the single injection amount and injection frequency of fuel injected into the cylinder according to the temperature required for the regeneration of the particulate filter, and prohibiting other operations on the vehicle except for exiting the forced regeneration strategy;

[0099] In implementation, the vehicle stationary state refers to the vehicle being in a stationary state without traveling, which is usually confirmed by a vehicle speed sensor, and the vehicle speed being zero indicates the vehicle is stationary. The engine idle state refers to the engine operating at a stable speed, which is suitable for regenerative operation. The particulate filter regeneration requires high exhaust gas temperature to burn off the accumulated soot particles, and in order to achieve the required regeneration temperature, the single injection amount and injection frequency of fuel injection into the cylinder are controlled to increase the exhaust gas temperature; during forced regeneration, in order to ensure the smooth progress of the regeneration process, other operations on the vehicle are prohibited except for exiting the forced regeneration strategy; for example, the driver is prohibited from accelerating, decelerating or other operations that affect engine load, and the operation of other systems (such as air conditioning, entertainment system, etc.) is prohibited to avoid affecting the regeneration process, and the purpose of prohibiting other operations is to ensure that the engine and exhaust system operate in a stable working condition to provide continuous high-temperature exhaust gas to complete the regeneration.

[0100] In response to determining that the particulate filter regeneration is completed, the forced regeneration strategy is exited.

[0101] In implementation, the regeneration process continues until the soot particles in the particulate filter are effectively removed, i.e. the differential pressure of the particulate filter returns to normal, and when the soot particles in the particulate filter are burned off, the differential pressure will decrease significantly and return to normal. When the particulate filter regeneration is completed, the forced regeneration strategy is exited, and the restrictions on the vehicle and engine are removed to allow the driver to perform normal driving operations.

[0102] In this embodiment, during forced regeneration, other operations on the vehicle are prohibited except for exiting the regeneration strategy, ensuring that the engine and exhaust system operate in a stable working condition to provide continuous high-temperature exhaust gas and ensure the smooth progress of the regeneration process. By prohibiting the driver from accelerating, decelerating or other operations that affect engine load, and prohibiting the operation of other systems (such as air conditioning, entertainment system, etc.), the risk of interruption of the regeneration process is avoided, ensuring the continuity and effectiveness of the regeneration process. Stable regeneration working condition and continuous high-temperature exhaust gas reduce the risk of interruption of the regeneration process, improve the success rate of regeneration, and avoid frequent regeneration failure leading to diesel engine oil dilution and engine failure.

[0103] In some embodiments, before the obtaining the historical number of parked regenerations of the particulate filter, comprising:

[0104] Obtaining the detected carbon load of the particulate filter;

[0105] In implementation, the carbon load refers to the mass of the soot particles accumulated in the particulate filter, usually in grams (g). The carbon load reflects the degree of clogging of the particulate filter and is an important parameter for determining the need for regeneration. The carbon load in the particulate filter can be calculated by detecting the pressure difference between the two ends of the particulate filter, i.e., the detected carbon load. The accumulation of soot particles increases the pressure difference of the particulate filter, and the greater the pressure difference, the higher the detected carbon load. By obtaining the detected carbon load of the particulate filter, the accumulation of soot particles in the particulate filter can be accurately determined.

[0106] In response to determining that the detected carbon load is greater than or equal to the default carbon load threshold, it is determined to perform on-road regeneration on the particulate filter.

[0107] In implementation, when the detected carbon load is greater than or equal to the default carbon load threshold, it indicates that the accumulation of soot particles in the particulate filter has reached a degree that requires regeneration, and it is determined to perform on-road regeneration on the particulate filter, preventing the particulate filter from being clogged and ensuring the normal operation of the particulate filter.

[0108] In response to determining that the detected carbon load is greater than or equal to the calibrated carbon load threshold, it is determined to perform off-road regeneration on the particulate filter; the calibrated carbon load threshold is greater than the default carbon load threshold.

[0109] In implementation, off-road regeneration is a regeneration operation performed when the vehicle is stationary, aiming to completely remove soot particles in the particulate filter. Off-road regeneration is usually triggered when there is a large accumulation of soot particles and on-road regeneration cannot effectively remove them. When it is determined that the detected carbon load is greater than or equal to the calibrated carbon load threshold (which is greater than the default carbon load threshold), it is determined to perform off-road regeneration on the particulate filter; this enables more thorough regeneration when there is a large accumulation of soot particles, preventing the particulate filter from being clogged and ensuring the normal operation of the particulate filter.

[0110] In this embodiment, by performing on-road regeneration or off-road regeneration according to the default carbon load threshold and the calibrated carbon load threshold after obtaining the detected carbon load of the particulate filter, the regeneration process can be accurately managed, ensuring that soot particles are effectively removed, preventing the particulate filter from being clogged, improving the operating efficiency and reliability of the vehicle, reducing user intervention, optimizing fuel economy, not only ensuring the normal operation of the particulate filter and preventing the particulate filter from being clogged and engine failure, but also improving the driving experience of the user.
