[0002] In emission regulations, particulate matter is an important indicator to measure vehicle emission levels. Faced with increasingly stringent emission regulations, gasoline engine vehicles have added particulate matter traps in the exhaust aftertreatment stage.

For example, the two frames shown in sequence can actually be performed substantially simultaneously or these frames can sometimes be performed in reverse order, depending on the functions / operations involved.

[0032] Among the methods of reducing particulate matter emissions from gasoline engines, the use of particulate matter filters has been adopted by more and more manufacturers. As mentioned above, gasoline engine particulate matter filters physically capture exhaust particulate matter, so the captured particulate matter needs to be burned by regeneration to avoid clogging the filter.

[0033] For the regeneration function, the key factors are the exhaust temperature and the amount of particulate matter (carbon load). The higher the exhaust temperature, the more conducive it is to regeneration, while the higher the carbon load, the more difficult it is to regenerate. Therefore, it is necessary to control the exhaust temperature in a reasonable way so that the carbon load is within a relatively easy regeneration range. In addition to controlling the engine ignition angle and coasting fuel cut-off behaviors, it is also necessary to give certain prompts to the driver, informing the driver that operating the vehicle in a certain way can play an important role in achieving the regeneration condition.

[0034] According to one embodiment of the present invention, on a vehicle equipped with a gasoline engine particulate matter filter, the exhaust temperature can be adjusted by controlling parameters such as the engine ignition angle and coasting fuel cut-off to meet the temperature requirements for regeneration of particulate matter in the filter. Secondly, based on the control of the engine's own parameters, one or more embodiments of the present invention add conditions for prompting the driver to intervene in the vehicle, so that the working conditions for particulate matter regeneration can be more easily achieved.

[0035] Reference now Figure 1 , Figure 1 FIG. 1 shows a schematic block diagram of a regeneration process driver prompting system 100 according to an embodiment of the present invention. Figure 1 As shown, the regeneration process driver prompting system 100 may include a first module 110 , a second module 120 , and a third module 130 . Optionally, the system 100 may further include a fourth module 140 .

[0036] The first module 110 may collect vehicle operating condition information, the current carbon load of the particulate matter trap, and external environment information, and may transmit the collected information to the second module 120 and the third module 130. The vehicle operating condition information may include, for example, one or more of the current engine exhaust temperature, the particulate matter trap operating temperature, the current engine workload, and the historical time of the active regeneration operation. The external environment information may include, for example, the external atmospheric pressure, the external temperature, etc.

[0037] In the system 100, the second module 120 can determine the first threshold value according to the first parameter preset by the system, the vehicle operating condition information collected by the first module 110, and the external environment information. Among them, the first threshold value is the critical value for prompting. It should be noted that the relevant operations, steps and principles for determining the first threshold value described in this article can be analogously applied to determining the second threshold value and the third threshold value. Correspondingly, there are second parameters and third parameters and second determination and third determination. In some examples according to the present invention, the first parameter (for example, and the second parameter, the third parameter) can be preset by the system, which can represent the size of the first threshold value (for example, and the corresponding second threshold value, the third threshold value) before the system is calibrated. The following describes this patent by taking the determination of the first threshold value as an example. In the system 100, the second module 120 can use information such as external environment information and historical data information of active regeneration operation to calibrate the first parameter (referred to as C1) predefined by the system, and transmit the calibrated value, that is, the first threshold value (referred to as TH1), to the third module 130. In some examples according to the present invention, the system can judge the current carbon load of the particulate matter trap by using a first threshold value (TH1) that changes continuously with factors such as the external environment and historical data of active regeneration operations, rather than using a constant threshold value to judge the current carbon load, thereby stimulating subsequent driver prompt operations and regeneration operations, which makes the judgment of the triggering conditions of the driver prompt operations and regeneration operations more flexible and accurate, and improves the flexibility and accuracy of the driver prompt system and the regeneration system. Specifically, as shown in the following formula, the second module 120 can calculate the penalty coefficient (denoted as K1) for the interruption of active regeneration based on the historical data information of the active regeneration operation:

[0038] K1= T1 / T2 (Formula 1)

[0039] Where T1 is the required time of the last active regeneration, and T2 is the actual execution time of the last active regeneration.

[0040] In the system 100, as shown in the following formula, the second module 120 can also determine and calculate the plateau correction coefficient (denoted as K2) according to the external environment information:

[0041] K2=1-K ef ×P (Formula 2)

[0042] Where P is the actual atmospheric pressure collected by the first module 110, K ef is the first coefficient. Optionally, the first coefficient K ef is a calibrable coefficient. Among them, when the first coefficient K ef A value of 0 means no plateau correction is performed, and K ef The calibration needs to ensure that the value of K2 is in the range of [0.7,1].

[0043] In the system 100, as shown in the following formula, the second module 120 can use the calculated penalty coefficient K1 and the plateau correction coefficient K2 to calibrate the first parameter C1 predefined by the system, and record the calibrated value as the first threshold TH1:

[0044] TH1=K1×K2×C1 / 1.6 (Formula 3).

[0045] The second module 120 can transmit the first threshold TH1 to the third module 130 for making a first judgment. Optionally, the third module 120 can make a first judgment only when the current system meets certain preconditions. The preconditions include, for example, but are not limited to, one or more of the following: first, the current engine exhaust temperature is greater than or equal to the particulate matter trap operating temperature; second, the current engine load is lower than a certain calibration value. The calibration value can be determined by the vehicle operating condition information and external environment information collected by the second module 120. It should be noted that the relevant operations, steps and principles for making the first judgment described in this article can be analogously applied to making the second judgment and the third judgment. It can be understood that the second threshold can be calculated using the second parameter accordingly, and the second judgment can be made accordingly; the third threshold can be calculated using the third parameter accordingly, and the third judgment can be made accordingly. Specifically, in the system 100, the third module 130 can compare the current carbon load with the first threshold TH1 (for example, and the second threshold, the third threshold) to make a first judgment (for example, and the second judgment, the third judgment) respectively. The specific judgment process is exemplarily described as follows.

[0046] If the third module 130 determines that the current carbon load is less than the first threshold TH1 (for example, Figure 2 As shown, it is 120%) ， Then the system can enter the silent stage. In the silent stage, since the carbon load in the particulate matter trap is at a low level, it is in the passive regeneration stage. The passive regeneration described in this article means that there is no need to intervene in the engine state, and the particulate matter regeneration process can be satisfied through normal operation. In this process, no prompt is required for the driver. That is, the third module 130 does not need to generate any prompt information in the silent stage.

[0047] If the third module 130 determines that the current carbon load is greater than or equal to the first threshold TH1 (for example, Figure 2As shown, it is 120%), the system can enter the driver prompt 1 stage. In the driver prompt 1 stage, the particulate matter collector has accumulated a certain amount of particulate matter, and a part of the particulate matter needs to be burned through active regeneration. From the perspective of promoting active regeneration, the fourth module 130 can send a first prompt request to the instrument through the CAN bus, and this request signal can be defined as "Driver Prompt 1". When the signal is sent on the bus, the instrument can remind the driver in text form that the particulate matter capture device is regenerating, and ask the driver to continue driving. In this way, the driver can be reminded to keep the vehicle in driving state as much as possible to avoid the engine being interrupted by parking or shutting down during active regeneration, resulting in incomplete combustion of particulate matter.

[0048] If the third module 130 determines that the current carbon load is greater than or equal to the second threshold TH2 (for example, Figure 2 As shown, it is 160%), the system can enter the driver prompting stage 2. As mentioned above, the second threshold TH2 can be calculated in a manner similar to the first threshold TH1, that is, calculated by the following formula:

[0049] TH2=K1×K2×C2 / 1.6 (Formula 4)

[0050] Where C2 is a second parameter predefined by the system. In the driver prompting stage 2, the particles in the trap have accumulated to a certain amount (e.g. Figure 2 As shown, more than 160%), active regeneration and combustion of particulate matter must be performed in time to avoid clogging the collector. The fourth module 140 can send a second prompt request to the instrument through the CAN bus, and this request signal can be defined as "Driver Prompt 2". When the signal is sent on the bus, the instrument needs to remind the driver in text that the particulate matter capture device is regenerating and requires the driver to continue driving, and it can be accompanied by a buzzer to assist the reminder. Compared with "Driver Prompt 1", "Driver Prompt 2" requires the driver to keep the vehicle in driving status, and the prompt needs to be more stringent. This is because in this case, relying solely on engine status control can no longer maintain sufficient exhaust temperature, and the vehicle needs to remain in driving status to meet the external demand for particulate matter regeneration.

[0051] If the third module 130 determines that the current carbon load is greater than or equal to the third threshold TH3 (for example, Figure 2 As shown, it is 180%), the system can enter the driver prompting stage 3. As mentioned above, the third threshold TH3 can be calculated in a manner similar to the first threshold TH1, that is, calculated by the following formula:

[0052] TH3=K1×K2×C3 / 1.6 (Formula 5)

[0053] C3 is the second parameter predefined by the system. In the driver prompting stage 3, the particulate matter in the trap has reached a level that is difficult to be burned and eliminated by regeneration. Therefore, in the driver prompting stage 2, the condition for triggering the engine fault light is added. The engine fault light can be directly triggered by the third module 130. At this stage, the driver needs to continue driving to avoid further aggravation of the blockage of the particulate matter trap due to the decrease in exhaust temperature. At the same time, the engine fault light reminds the driver to send the vehicle to the maintenance station for further treatment.

[0054] At the same time, the third module 130 can determine whether the current vehicle operating condition meets the stop condition, and stop sending the prompt information when the stop condition is met. For example, the stop condition may include one or more of the following: (1) the regeneration operation has been completed; (2) the engine load is sufficient to drive the regeneration operation and there is no need to prompt the driver temporarily; (3) the engine is shut down; and (4) the GPF particulate matter trap sensor is faulty.

[0055] Figure 2 FIG. 1 shows an exemplary parameter correspondence table according to an embodiment of the present invention. Figure 3 , Figure 3 A schematic flow chart of a regeneration process driver prompting method 300 according to an embodiment of the present invention is shown.

[0056] In step S310 of the method 100, vehicle operating condition information, current carbon load of the particulate matter trap, and external environment information may be collected. The vehicle operating condition information may include, for example, one or more of the current engine exhaust temperature, the particulate matter trap operating temperature, the current engine workload, and the history of active regeneration operation. The external environment information may include, for example, external atmospheric pressure, external temperature, etc.

[0057] In step S320, the first threshold value (for example, as well as the second threshold value and the third threshold value) can be determined according to the first parameter preset by the system, the collected vehicle operating condition information and the external environment information. The penalty coefficient K1 for interruption of active regeneration can be calculated by using the formula 1 as described above. The plateau correction coefficient K2 can also be calculated by using the formula 2 as described above. Further, the first threshold value TH1 can be calculated by using the formula 3 as described above. Further, the second threshold value TH2 can be calculated by using the formula 4 as described above. Further, the third threshold value TH3 can be calculated by using the formula 5 as described above.

[0058] In step S330, a first judgment (for example, a second judgment, a third judgment) can be made based on the current carbon load and a first threshold value (for example, a second threshold value, a third threshold value), and a prompt message can be generated. Optionally, in S330, the above judgment can be made only when certain preconditions are met. The preconditions include, for example, but are not limited to, one or more of the following: first, the current engine exhaust temperature is greater than or equal to the particulate matter collector operating temperature; second, the current engine load is lower than a certain calibration value. The calibration value can be determined by vehicle operating condition information and external environment information. Specifically, step S330 can exemplarily include the following steps.

[0059] If it is determined that the current carbon load is less than the first threshold TH1 (for example, Figure 2 As shown, it is 120%) ， The system can enter the silent stage. In the silent stage, since the carbon load in the particulate matter filter is at a low level, it is in the passive regeneration stage. That is, there is no need to intervene in the engine state, and the particulate matter regeneration process can be satisfied through normal operation. No prompts are required to the driver during this process.

[0060] If it is determined that the current carbon load is greater than or equal to the first threshold TH1 (for example, Figure 2 As shown in the figure, it is 120%), then the driver prompt stage 1 can be entered. In the driver prompt stage 1, a part of the particulate matter needs to be burned by active regeneration. From the perspective of promoting active regeneration, the first prompt request can be sent to the instrument through the CAN bus, and this request signal can be defined as "driver prompt 1". When this signal is sent on the bus, the instrument can remind the driver in text form that the particulate matter capture device is regenerating and ask the driver to continue driving.

[0061] If it is determined that the current carbon load is greater than or equal to the second threshold TH2 (for example, Figure 2 As shown in the figure, it is 160%), then the driver prompt stage 2 can be entered. In the driver prompt stage 2, active regeneration and combustion of particulate matter must be carried out in time to avoid clogging the trap. A second prompt request can be sent to the instrument through the CAN bus, and this request signal can be defined as "Driver Prompt 2". When this signal is sent on the bus, the instrument needs to remind the driver in text form that the particulate matter trap is being regenerated, requiring the driver to continue driving, and it can be accompanied by a buzzer to assist the reminder.

[0062] If it is determined that the current carbon load is greater than or equal to the third threshold TH3 (for example, Figure 2As shown in the figure, it is 180%), then it can enter the driver prompt stage 3. In the driver prompt stage 3, the particulate matter in the trap has reached a level that is difficult to be burned and eliminated by regeneration. Therefore, in the driver prompt stage 2, the condition for triggering the engine fault light is added. In this stage, the driver needs to continue driving to avoid further aggravation of the blockage of the particulate matter trap due to the decrease in exhaust temperature. At the same time, the engine fault light reminds the driver to send the vehicle to the repair station for further treatment.

[0063] It should be noted that the above four driver prompting stages are shown in the form of examples and are not intended to limit the prompting stages to the above four stages. Specifically, the system 100 may include one or more stages. In some embodiments of the present invention, on a vehicle equipped with a gasoline engine particulate matter filter, the above-mentioned several stages of prompting can ensure that the particulate matter filter system is always in an efficient and safe working state.

[0064] In addition, it is also possible to determine whether the current vehicle operating condition satisfies a stop condition, and stop sending the prompt information when the stop condition is met. For example, the stop condition may include one or more of the following: (1) the regeneration operation has been completed; (2) the engine load is sufficient to drive the regeneration operation and there is no need to prompt the driver temporarily; (3) the engine is shut down; and (4) the GPF particulate matter trap sensor is faulty.
