Background Art

[0002] To ensure the trapping effect of the GPF (Gasoline Particulate Filter) on emission particles, the GPF in related technologies is usually equipped with a corresponding monitoring device to achieve real-time monitoring of the working state of the GPF. However, in this way, the installation of the monitoring device will bring additional cost burdens and space occupation problems. Furthermore, on the premise of realizing the detection of the GPF state, how to install the GPF, the monitoring device, and other components in the limited body space has become one of the problems to be solved urgently in the body design process. Summary of the Invention

[0005] The pressure detection component is configured to detect the current pressure of the gasoline particulate filter to determine the carbon accumulation state of the gasoline particulate filter, and the current pressure includes the current intake pressure or the current outlet pressure.

[0006] In this way, in the embodiment of the present application, the carbon accumulation state of the gasoline particulate filter can be determined through the current intake pressure of the gasoline particulate filter or the current outlet pressure of the gasoline particulate filter detected by the pressure detection component, thereby realizing the state detection and regeneration control of the gasoline particulate filter. Moreover, it is possible to avoid the situation where the current intake pressure and the current outlet pressure of the gasoline particulate filter need to be obtained simultaneously by the pressure detection component to realize the state detection and regeneration control of the gasoline particulate filter. Therefore, the function and structure of the pressure detection component are simplified, and the body space occupied by the pressure detection component is reduced, so that more body space resources can be allocated to the gasoline particulate filter or other gas treatment components in the vehicle exhaust gas treatment device to improve the vehicle exhaust gas treatment effect.

[0007] In some embodiments of the present application, the device further includes a cylinder body and a three-way catalytic converter, and the gasoline particulate filter and the three-way catalytic converter are sequentially arranged inside the cylinder body.

[0008] Thus, in the embodiments of the present application, the vehicle exhaust treatment device can be realized based on the three-way catalytic converter and the gasoline particulate filter sequentially arranged inside the cylinder, and the gas to be discharged from the vehicle can pass through the three-way catalytic converter and the gasoline particulate filter successively, thereby ensuring the reliable capture of particulate matters such as soot in the gas to be discharged from the vehicle, and further reducing the pollution of the vehicle gas such as the engine exhaust gas to the external environment of the vehicle.

[0020] According to the currently detected air pressure of the gasoline particulate filter, determine the carbon accumulation state of the gasoline particulate filter, wherein the currently detected air pressure is the current intake air pressure or the current exhaust air pressure.

[0021] Thus, in the embodiments of the present application, the carbon accumulation state of the gasoline particulate filter can be determined through the currently detected intake air pressure or the currently detected exhaust air pressure of the gasoline particulate filter detected by the air pressure detection component. Thereby, the state detection and regeneration control of the gasoline particulate filter are realized. Moreover, the situation of simultaneously obtaining the current intake air pressure and the current exhaust air pressure of the gasoline particulate filter through the air pressure detection component to realize the state detection and regeneration control of the gasoline particulate filter can be avoided. Therefore, the function and structure of the air pressure detection component are simplified, and the body space occupied by the air pressure detection component is reduced. Thus, more body space resources can be allocated to the gasoline particulate filter or other gas treatment components in the vehicle exhaust treatment device to improve the vehicle exhaust treatment effect.

[0022] In some embodiments of the present application, the step of determining the carbon accumulation state of the gasoline particulate filter according to the currently detected air pressure of the gasoline particulate filter includes:

[0024] Thus, in the embodiments of the present application, the carbon accumulation state of the gasoline particulate filter can be determined according to the currently detected air pressure and the preset air pressure, thereby realizing a robust determination of the carbon accumulation state of the gasoline particulate filter.

[0025] In some embodiments of the present application, the carbon accumulation state is used to indicate whether the gasoline particulate filter can be regenerated.

[0030] Thus, in the embodiments of the present application, it is possible to determine the current particulate matter loading of the gasoline particulate filter according to the current air pressure and the preset air pressure, and determine whether the gasoline particulate filter can be regenerated according to the current particulate matter loading, thereby ensuring a stable determination of whether the gasoline particulate filter can be regenerated.

[0031] In some embodiments of the present application, when the current air pressure is the current intake air pressure, the preset air pressure is the preset outlet air pressure, and when the current air pressure is the current outlet air pressure, the preset air pressure is the preset intake air pressure. Determining the current particulate matter loading of the gasoline particulate filter according to the current air pressure and the preset air pressure includes:

[0032] Determining the current particulate matter loading according to the pressure difference between the current air pressure and the preset air pressure.

[0033] Thus, in the embodiments of the present application, it is possible to determine the current particulate matter loading of the gasoline particulate filter according to the pressure difference between the current air pressure and the preset air pressure, thereby achieving a stable determination of the current particulate matter loading.

[0034] In some embodiments of the present application, determining the carbon accumulation state according to the current particulate matter loading includes:

[0035] When the current particulate matter loading is greater than or equal to the preset particulate matter loading threshold, determining that the gasoline particulate filter needs to be regenerated; and / or,

[0036] When the current particulate matter loading is less than the preset particulate matter loading threshold, determining that the gasoline particulate filter does not need to be regenerated.

[0037] Thus, in the embodiments of the present application, it is possible to determine that the gasoline particulate filter needs to be regenerated when the current particulate load is greater than or equal to a preset particulate load threshold; and / or determine that the gasoline particulate filter does not need to be regenerated when the current particulate load is less than the preset particulate load threshold, thereby ensuring a robust determination of the carbon accumulation state of the gasoline particulate filter.

[0038] In some embodiments of the present application, the method further includes:

[0039] When the gasoline particulate filter needs to be regenerated, regenerate the gasoline particulate filter.

[0040] Thus, in the embodiments of the present application, when the gasoline particulate filter needs to be regenerated, the gasoline particulate filter is regenerated, thereby ensuring timely regeneration of the gasoline particulate filter.

[0041] In some embodiments of the present application, the carbon accumulation state is used to indicate the execution result of the regeneration process of the gasoline particulate filter.

[0042] Thus, in the embodiments of the present application, the execution effect of the regeneration process of the gasoline particulate filter can be determined according to the current air pressure and the preset air pressure, so that timely monitoring of the regeneration process of the gasoline particulate filter can be realized, thereby ensuring the robust operation of the vehicle exhaust treatment system.

[0045] Thus, in the embodiments of the present application, the execution result of the regeneration process of the gasoline particulate filter can be determined after regenerating the gasoline particulate filter, thereby ensuring the effectiveness and reliability of the execution result of the regeneration process.

[0046] In some embodiments of the present application, the preset air pressure includes a preset intake air pressure and a preset outlet air pressure, and determining the carbon accumulation state according to the current air pressure and the preset air pressure includes:

[0047] According to the current air pressure and one of the preset intake air pressure and the preset outlet air pressure, determine a first air pressure difference;

[0048] According to the preset intake air pressure and the preset outlet air pressure, determine a second air pressure difference;

[0049] According to the first air pressure difference and the second air pressure difference, determine the carbon accumulation state.

[0050] Thus, in the embodiments of the present application, the first pressure difference can be determined according to the current air pressure and one of the preset intake air pressure and the preset outlet air pressure, the second pressure difference can be determined according to the preset intake air pressure and the preset outlet air pressure, and the regeneration processing result of the gasoline particulate filter can be determined according to the first pressure difference and the second pressure difference, thereby ensuring the robust determination of the execution result of the regeneration processing of the gasoline particulate filter.

[0051] In some embodiments of the present application, the determining the carbon accumulation state according to the first pressure difference and the second pressure difference includes:

[0052] When the ratio of the first pressure difference to the second pressure difference is greater than or equal to a preset ratio threshold, it is determined that the regeneration process of the gasoline particulate filter is executed normally; and / or,

[0053] When the ratio of the first pressure difference to the second pressure difference is less than the preset ratio threshold, it is determined that the regeneration process of the gasoline particulate filter is executed abnormally.

[0054] Thus, in the embodiments of the present application, when the ratio of the first pressure difference to the second pressure difference is greater than or equal to the preset ratio threshold, it can be determined that the regeneration process of the gasoline particulate filter is executed normally, and / or when the ratio of the first pressure difference to the second pressure difference is less than the preset ratio threshold, it can be determined that the regeneration process of the gasoline particulate filter is executed abnormally, thereby ensuring the reliable determination of the execution result of the regeneration process of the gasoline particulate filter.

[0055] In some embodiments of the present application, the method further includes:

[0056] When the regeneration process of the gasoline particulate filter is executed abnormally, a preset prompt message is fed back and / or the gasoline particulate filter is regenerated.

[0057] Thus, in the embodiments of the present application, when the regeneration process of the gasoline particulate filter is executed abnormally, a preset prompt message can be fed back and / or the gasoline particulate filter can be regenerated, thereby ensuring the robust operation of the vehicle.

Moreover, it can avoid the situation where it is necessary to simultaneously obtain the current intake air pressure and the current outlet air pressure of the gasoline particulate filter through the air pressure detection component to realize the state detection and regeneration control of the gasoline particulate filter. Therefore, the function and structure of the air pressure detection component are simplified, and the body space occupied by the air pressure detection component is reduced.

[0079] The following details the implementation manners of the present application. Examples of the implementation manners are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The implementation manners described below with reference to the accompanying drawings are exemplary only for explaining the implementation manners of the present application and should not be construed as limiting the implementation manners of the present application.

[0080] With the continuous development and progress of the vehicle industry, there have been significant improvements and strict definitions for the fuel efficiency and exhaust emission standards of gasoline vehicles, especially for the requirement of PN (Particulate Number).

[0081] Therefore, to adapt to the gradually changing fuel efficiency and exhaust emission standards of gasoline vehicles, related technologies have proposed a technology for capturing emission particles to reduce the emission particles of the whole vehicle, that is, a tail gas treatment device with a GPF (Gasoline Particulate Filter) as the core is set in the vehicle.

[0082] Among them, the exhaust gas treatment device consists of multiple key components, such as GPF, differential pressure sensor, differential pressure pipeline, etc. As the core, GPF is responsible for directly filtering solid particles in the exhaust gas. The differential pressure sensor and differential pressure pipeline play a crucial monitoring role. It can be understood that the design intention of the differential pressure sensor and differential pressure pipeline is to realize real-time monitoring of the working state of GPF by accurately measuring the pressure difference of the engine exhaust gas before and after flowing through GPF, such as monitoring whether GPF is blocked.

[0083] In the related technology, the differential pressure sensor and differential pressure pipeline in the exhaust gas treatment device usually adopt a dual-pipeline layout, that is, a set of differential pressure sensor and corresponding pipeline are respectively arranged at the front end and the rear end of GPF to measure the pressure difference of the engine exhaust gas before and after flowing through GPF.

[0084] To clearly illustrate the differential pressure sensor and differential pressure pipeline in the related technology, please refer to Figure 1 , Figure 1 which is a schematic diagram of the exhaust gas treatment device adopting a dual-pipeline layout. As Figure 1 shown, the exhaust gas treatment device includes a catalytic converter assembly 1, a differential pressure sensor 2, a differential pressure rubber hose 3, a differential pressure hard pipe 4, a differential pressure hard pipe base 5, a first three-way catalyst (TWC) 12, a second three-way catalyst 13, a GPF 14, a first end cone 15 and a second end cone 16.

[0085] Among them, the first end cone 15 is arranged at the front end of the cylinder body 11, and the second end cone 16 is arranged at the rear end of the cylinder body 11. The first three-way catalyst 12, the second three-way catalyst 13 and the GPF 14 are fixedly arranged inside the cylinder body. In the cylinder body 11, differential pressure hard pipes 4 are arranged before and after the GPF 14. The differential pressure hard pipes 4 are installed by screwing through the differential pressure hard pipe bases welded on the cylinder body and the housing. The other end of the differential pressure hard pipe 4 is connected to the differential pressure rubber hose through a buckle. The other end of the differential pressure rubber hose is connected to the differential pressure sensor.

[0086] Thus, the differential pressure sensor detects the gas pressure P 前 before flowing through the GPF 14 and the gas pressure P 后 after flowing through the GPF 14 through the differential pressure hard pipes 4 arranged before and after the GPF 14, and reads the exhaust gas flow rate at the same time. When (P 前 -P 后 ) is higher than the preset value, the GPF 14 performs active regeneration.

[0087] It can be understood that, as Figure 1In the exhaust gas treatment device shown, differential pressure rigid pipes need to be arranged both in front of and behind the GPF 14. At the same time, the distance between the second three-way catalytic converter 13 and the GPF 14 is usually greater than 25 mm (millimeters) to facilitate the arrangement of the differential pressure rigid pipes. Therefore, in the catalytic converter assembly 1 with limited volume, the volume of the catalytic converter is reduced. For example, the size of the second three-way catalytic converter 13 is 132.1 mm * 50 mm, and the size of the GPF 14 is 132.1 mm * 101.6 mm.

[0088] It can also be understood that, similar to Figure 1 Although the double-pipeline layout mode shown is technically mature and reliable, it inevitably brings additional cost burdens and space occupation problems. For example, due to the deployment of double sets of differential pressure sensors and their supporting pipelines, wire harnesses and other components, the material cost and assembly complexity increase accordingly, and more space needs to be occupied in the limited body space. Therefore, how to explore a more compact and efficient design solution while ensuring the monitoring accuracy and reliability has become one of the challenges currently faced by the vehicle industry.

[0089] Based on the above possible problems, please refer to Figure 2 , an embodiment of the present application provides a vehicle exhaust gas treatment device 1000. The vehicle exhaust gas treatment device 1000 includes a gasoline particulate filter 1100 and a gas pressure detection component 1200. The gas pressure detection component 1200 is configured to detect the current gas pressure of the gasoline particulate filter 1100 to determine the carbon accumulation state of the gasoline particulate filter 1100. The current gas pressure includes the current intake gas pressure or the current exhaust gas pressure.

[0090] Specifically, in the embodiment of the present application, the vehicle exhaust gas treatment device 1000 can detect the intake gas pressure or the exhaust gas pressure of the gasoline particulate filter 1100 at the current moment through the gas pressure detection component 1200, that is, the current intake gas pressure or the current exhaust gas pressure. Moreover, the vehicle exhaust gas treatment device 1000 can determine the carbon accumulation state of the gasoline particulate filter 1100 through the current intake gas pressure or the current exhaust gas pressure.

[0091] Thus, in the embodiment of the present application, the carbon accumulation state of the gasoline particulate filter 1100 can be determined by the current intake air pressure detected by the air pressure detection component 1200 or the current outlet air pressure of the gasoline particulate filter 1100, thereby realizing the state detection and regeneration control of the gasoline particulate filter 1100. Moreover, it is possible to avoid the situation where the current intake air pressure and the current outlet air pressure of the gasoline particulate filter 1100 need to be obtained simultaneously by the air pressure detection component 1200 to realize the state detection and regeneration control of the gasoline particulate filter 1100. Therefore, the function and structure of the air pressure detection component 1200 are simplified, and the body space occupied by the air pressure detection component 1200 is reduced, so that more body space resources can be allocated to the gasoline particulate filter 1100 or other gas treatment components in the vehicle exhaust treatment device 1000 to improve the vehicle exhaust treatment effect.

[0092] In one example, the current air pressure of the gasoline particulate filter 1100 is the current intake air pressure of the gasoline particulate filter 1100. Furthermore, the vehicle exhaust treatment device 1000 can determine the air pressure difference before and after the vehicle exhaust passing through the gasoline particulate filter 1100 according to the calibrated outlet air pressure of the gasoline particulate filter 1100 pre-calibrated, so as to determine the carbon accumulation state of the gasoline particulate filter 1100, such as determining whether the gasoline particulate filter 1100 needs active regeneration.

[0093] In one example, the current air pressure of the gasoline particulate filter 1100 is the current outlet air pressure of the gasoline particulate filter 1100. Furthermore, the vehicle exhaust treatment device 1000 can determine the air pressure difference before and after the vehicle exhaust passing through the gasoline particulate filter 1100 according to the calibrated intake air pressure of the gasoline particulate filter 1100 pre-calibrated, so as to determine the carbon accumulation state of the gasoline particulate filter 1100, such as determining whether the gasoline particulate filter 1100 needs active regeneration.

[0094] In one example, the current air pressure of the gasoline particulate filter 1100 is the current outlet air pressure of the gasoline particulate filter 1100. Furthermore, the vehicle exhaust treatment device 1000 can determine whether the "current outlet air pressure of the gasoline particulate filter 1100" matches the "calibrated outlet air pressure of the gasoline particulate filter 1100 pre-calibrated" according to the calibrated outlet air pressure of the gasoline particulate filter 1100 pre-calibrated, so as to determine the carbon accumulation state of the gasoline particulate filter 1100, such as determining whether the gasoline particulate filter 1100 needs active regeneration.

[0095] In one example, the air pressure detection component 1200 includes a sensor for detecting air pressure.

[0096] Please refer to again Figure 2, in some embodiments of the present application, the vehicle exhaust treatment device 1000 further includes a cylinder body 1300 and a three-way catalytic converter 1400. The gasoline particulate filter 1100 and the three-way catalytic converter 1400 are sequentially arranged inside the cylinder body 1300.

[0097] Specifically, to further improve the treatment effect of the vehicle's exhaust gas to be discharged, in the embodiments of the present application, the vehicle exhaust treatment device 1000 further includes a three-way catalytic converter 1400. Furthermore, based on the three-way catalytic converter 1400 and the gasoline particulate filter 1100 sequentially arranged inside the cylinder body 1300, when the vehicle's exhaust gas to be discharged, such as the engine-generated gas, is discharged along the cylinder body 1300 to the external environment of the vehicle, the engine-generated gas can be sequentially treated by the three-way catalytic converter 1400 and the gasoline particulate filter 1100, thereby ensuring that the vehicle exhaust treatment device 1000 can robustly capture particulate matters such as soot in the vehicle engine exhaust gas, and thus reducing the pollution of vehicle gases such as engine exhaust gas to the external environment of the vehicle.

[0098] In this way, in the embodiments of the present application, the vehicle exhaust treatment device 1000 can be realized based on the three-way catalytic converter 1400 and the gasoline particulate filter 1100 sequentially arranged inside the cylinder body 1300, and the vehicle's exhaust gas to be discharged can sequentially pass through the three-way catalytic converter 1400 and the gasoline particulate filter 1100, thereby ensuring the reliable capture of particulate matters such as soot in the vehicle's exhaust gas to be discharged, and further reducing the pollution of vehicle gases such as engine exhaust gas to the external environment of the vehicle.

[0099] In some embodiments of the present application, the three-way catalytic converter 1400 includes a pre-stage three-way catalytic converter 1410 and a post-stage three-way catalytic converter 1420. The pre-stage three-way catalytic converter 1410, the gasoline particulate filter 1100, and the post-stage three-way catalytic converter 1420 are sequentially arranged inside the cylinder body 1300.

[0100] Specifically, to further improve the treatment effect of the vehicle's exhaust gas to be discharged, in the embodiments of the present application, the vehicle exhaust treatment device 1000 may include a pre-stage three-way catalytic converter 1410 and a post-stage three-way catalytic converter 1420. Furthermore, based on the pre-stage three-way catalytic converter 1410, the gasoline particulate filter 1100, and the post-stage three-way catalytic converter 1420 sequentially arranged inside the cylinder body 1300, when the vehicle gas such as engine exhaust gas is discharged along the cylinder body 1300 to the external environment of the vehicle, the engine exhaust gas can be sequentially treated by the pre-stage three-way catalytic converter 1410, the gasoline particulate filter 1100, and the post-stage three-way catalytic converter 1420, thereby ensuring that the vehicle exhaust treatment device 1000 can robustly capture particulate matters such as soot in the vehicle engine exhaust gas, and thus reducing the pollution of vehicle gases such as engine exhaust gas to the external environment of the vehicle.

[0101] Thus, in the embodiments of the present application, the vehicle exhaust treatment device 1000 can be implemented based on the pre-stage three-way catalytic converter 1410, gasoline particulate filter 1100, and post-stage three-way catalytic converter 1420 sequentially arranged inside the cylinder body 1300, and the gas to be discharged in the vehicle can pass through the pre-stage three-way catalytic converter 1410, gasoline particulate filter 1100, and post-stage three-way catalytic converter 1420 in sequence, thereby further ensuring the reliable capture of particulate matters such as soot in the gas to be discharged from the vehicle, and further reducing the pollution of vehicle gases such as engine exhaust gases to the external environment of the vehicle.

[0102] In addition, it can be understood that the number of the pre-stage three-way catalytic converters 1410 and the number of the post-stage three-way catalytic converters 1420 can both be set according to actual situations, for example, both are set to 1.

[0103] In some embodiments of the present application, the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 are arranged at intervals inside the cylinder body 1300, and the distance between the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 is between 5 mm and 40 mm.

[0104] Specifically, in the embodiments of the present application, when the air pressure detection component 1200 is used to detect the intake air pressure of the gasoline particulate filter 1100, there is no need to leave a large gap between the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 for the layout of the differential pressure pipeline. Furthermore, in the embodiments of the present application, the distance between the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 can be between 5 mm and 40 mm.

[0105] Thus, in the embodiments of the present application, the distance between the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 can be between 5 mm and 40 mm, so as to simplify the structure of the vehicle exhaust treatment device 1000.

[0106] In addition, it can be understood that since the air pressure detection component 1200 is used to detect one of the intake air pressure and the outlet air pressure of the gasoline particulate filter 1100, compared with the differential pressure sensor and the differential pressure pipeline arranged in the double-pipeline layout in the related art, the body space occupied by the air pressure detection component 1200 is relatively small. Therefore, the volume of other components of the vehicle exhaust treatment device 1000 except the air pressure detection component 1200 can be increased correspondingly.

[0107] For example, in one example, when the air pressure detection component 1200 is used to detect the intake air pressure of the gasoline particulate filter 1100, there is no need to leave a large gap between the gasoline particulate filter 1100 and the post-stage three-way catalytic converter 1420 for arranging the differential pressure pipeline. Therefore, the volume of the post-stage three-way catalytic converter 1420 can be increased accordingly, that is, the height of the post-stage three-way catalytic converter 1420 is greater than or equal to 132.1 mm, and the width of the post-stage three-way catalytic converter 1420 is greater than or equal to 70 mm. In other words, the size of the post-stage three-way catalytic converter 1420 is greater than or equal to 132.1 mm * 70 mm, and the size is larger than that of the second three-way catalytic converter 13 with a size of 132.1 mm * 50 mm in the related art above.

[0108] In some embodiments of the present application, the air pressure detection component 1200 includes an air pressure sensor 1210 and an air pipeline 1220. The air pressure sensor 1210 is connected to the cylinder body 1300 through the air pipeline 1220 to detect the current air pressure.

[0109] Specifically, in the embodiment of the present application, the air pressure detection component 1200 is composed of an air pressure sensor 1210 and an air pipeline 1220. The air pipeline 1220 is connected to the cylinder body 1300. Furthermore, the air pressure sensor 1210 can detect the current air pressure of the gasoline particulate filter 1100 through the air pipeline 1220.

[0110] For a clearer description of the air pressure sensor 1210 in the embodiments of the present application, please refer to Figure 3 , Figure 3 which is a schematic diagram of the air pressure sensor in some embodiments of the present application. That is, the air pressure sensor 1210 in the embodiments of the present application can be as Figure 3 shown.

[0111] In this way, in the embodiment of the present application, the air pressure detection component 1200 can be realized by the air pressure sensor 1210 and the air pipeline 1220.

[0112] In some embodiments of the present application, the air pipeline 1220 includes a hard pipe 1221, a rubber pipe 1222, and a hard pipe base 1223. The hard pipe base 1223 is fixedly arranged on the cylinder body 1300. One end of the hard pipe 1221 is connected to the hard pipe base 1223, and the other end of the hard pipe 1221 is connected to the air pressure sensor 1210 through the rubber pipe 1222.

[0113] Specifically, in this embodiment of the present application, the air pipeline 1220 includes a hard tube 1221, a rubber tube 1222, and a hard tube base 1223. The hard tube base 1223 is responsible for securing the hard tube 1221 and connecting the hard tube 1221 to the cylinder 1300. Furthermore, a section of the hard tube 1221 is fixed to the hard tube base 1223, while the other end of the hard tube 1221 is connected to one end of the rubber tube 1222. The other end of the rubber tube 1222 is connected to the air pressure sensor 1210. Consequently, the air pressure sensor 1210 can detect the current air pressure of the gasoline particulate filter 1100 through the sequentially connected rubber tube 1222, the hard tube 1221, and the cylinder 1300.

[0114] To more clearly illustrate the hard tube 1221, the rubber tube 1222 and the hard tube base 1223 in the embodiment of the present application, please refer to Figure 4 、 Figure 5 and Figure 6 , Figure 4 This is a schematic diagram of a hard tube in some embodiments of the present application. Figure 5 This is a schematic diagram of a hose in some embodiments of the present application. Figure 6 This is a schematic diagram of a hard pipe base in some embodiments of the present application, that is, the hard pipe 1221 in the embodiment of the present application can be as follows Figure 4 As shown, the hose 1222 in the embodiment of the present application can be as Figure 5 As shown, the hard tube base 1223 in the embodiment of the present application can be as Figure 6 shown.

[0115] In such Figure 5 In one example shown, the air line 1220 in the embodiment of the present application further includes a hose ferrule 1224 for limiting the movement of the hose 1222 .

[0116] It is understandable that in Figure 2 In the vehicle exhaust treatment device 1000 shown, the hard tube base 1223 is arranged on the cylinder 1300, between the front-stage three-way catalytic converter 1410 and the gasoline particulate filter 1100. Furthermore, the air pressure sensor 1210 can detect the intake air pressure of the gasoline particulate filter 1100 through the rubber hose 1222, the hard tube 1221 and the cylinder 1300 connected in sequence.

[0117] It can also be understood that when a vehicle exhaust treatment device 1000 of other shapes or structures is used, the hard tube base 1223 is arranged on the cylinder 1300, between the rear-stage three-way catalytic converter 1410 and the gasoline particulate filter 1100. Furthermore, the air pressure sensor 1210 can detect the outlet air pressure of the gasoline particulate filter 1100 through the rubber hose 1222, the hard tube 1221 and the cylinder 1300 that are connected in sequence.

[0118] In addition, it can also be understood that compared with the dual-pipeline layout in the related art, the embodiment of the present application can reduce one differential pressure pipeline. Therefore, the materials of one differential pressure rubber hose, buckle, differential pressure hard pipe, and differential pressure hard pipe base can be reduced, so the cost is relatively low and the weight is relatively small.

[0119] In this way, in the embodiment of the present application, the air pressure detection component 1200 can be realized through the air pressure sensor 1210, hard pipe 1221, rubber hose 1222, and hard pipe base 1223.

[0120] In some embodiments of the present application, an intake end cone 1500 is provided at the intake end of the cylinder body 1300, and an outlet end cone 1600 is provided at the outlet end of the cylinder body 1300.

[0121] Specifically, in order to optimize the air flow distribution, reduce the exhaust back pressure, and adapt to the compact layout, in the embodiment of the present application, an intake end cone 1500 can be provided at the intake end of the cylinder body 1300, and an outlet end cone 1600 can be provided at the outlet end of the cylinder body 1300.

[0122] In this way, in the embodiment of the present application, an intake end cone 1500 can be provided at the intake end of the cylinder body 1300, and an outlet end cone 1600 can be provided at the outlet end of the cylinder body 1300. Thus, during the process that the vehicle exhaust gas is discharged along the cylinder body 1300 to the vehicle outer environment, the air flow distribution can be optimized to a certain extent, the exhaust back pressure can be reduced, and the cylinder body 1300 can be adapted to the compact body space to a certain extent.

[0123] Please refer to Figure 7 , corresponding to the above vehicle exhaust gas treatment device, the embodiment of the present application further provides a vehicle control method, which is applied to the above vehicle exhaust gas treatment device, and the method includes:

[0124] 01: Determine the carbon accumulation state of the gasoline particulate filter according to the currently detected air pressure of the gasoline particulate filter, where the current air pressure is the current intake air pressure or the current outlet air pressure.

[0125] The embodiment of the present application further provides an electronic device, which includes a memory and a processor. The vehicle control method of the embodiment of the present application can be realized by the electronic device of the embodiment of the present application. Specifically, a computer program is stored in the memory, and the processor is used to determine the carbon accumulation state of the gasoline particulate filter according to the currently detected air pressure of the gasoline particulate filter, where the current air pressure is the current intake air pressure or the current outlet air pressure.

[0126] Specifically, in the embodiment of the present application, a vehicle (or an electronic device, or a vehicle exhaust treatment system) can detect the current intake air pressure or the current outlet air pressure of a gasoline particulate filter in the vehicle exhaust treatment device according to the air pressure detection component in the above vehicle exhaust treatment device, and determine the carbon accumulation state of the gasoline particulate filter according to the current intake air pressure or the current outlet air pressure of the gasoline particulate filter. For example, it can be determined whether the gasoline particulate filter can be regenerated according to the current intake air pressure or the current outlet air pressure of the gasoline particulate filter.

[0127] It can be understood that the structure and working principle of the vehicle exhaust treatment device can be referred to the previous text. To avoid repetition, it will not be repeated here.

[0128] In this way, in the embodiment of the present application, the carbon accumulation state of the gasoline particulate filter can be determined through the current intake air pressure of the gasoline particulate filter or the current outlet air pressure of the gasoline particulate filter detected by the air pressure detection component, thereby realizing the state detection and regeneration control of the gasoline particulate filter. Moreover, it can avoid the situation where it is necessary to simultaneously obtain the current intake air pressure and the current outlet air pressure of the gasoline particulate filter through the air pressure detection component to realize the state detection and regeneration control of the gasoline particulate filter. Therefore, the function and structure of the air pressure detection component are simplified, and the body space occupied by the air pressure detection component is reduced, so that more body space resources can be allocated to the gasoline particulate filter or other gas treatment components in the vehicle exhaust treatment device to improve the vehicle exhaust treatment effect.

[0129] Please refer to Figure 8 , in some embodiments of the present application, step 01 includes:

[0130] 010: Determine the carbon accumulation state according to the current air pressure and the preset air pressure, where the preset air pressure is determined according to the current exhaust gas flow rate of the vehicle engine.

[0131] The processor in the embodiment of the present application is further configured to determine the carbon accumulation state according to the current air pressure and the preset air pressure, where the preset air pressure is determined according to the current exhaust gas flow rate of the vehicle engine.

[0132] Specifically, in the embodiment of the present application, the vehicle can determine the carbon accumulation state of the gasoline particulate filter at the current moment according to the current intake air pressure or the current outlet air pressure of the gasoline particulate filter detected by the air pressure detection component, in combination with the preset air pressure determined by using the current exhaust gas flow rate of the vehicle engine.

[0133] In one example, when the preset air pressure can indicate that the gasoline particulate filter is not carbon-accumulated, when the vehicle engine delivers gas to the gasoline particulate filter with different exhaust gas flow rates, the air pressure P before the gas passes through the gasoline particulate filter 前理论 , and the air pressure P after the gas passes through the gasoline particulate filter后理论 To illustrate the embodiments of the present application more clearly, please refer to Figure 9 , Figure 9 which is a schematic diagram of an application scenario in some embodiments of the present application. That is, as Figure 9 shown, a fresh or unsooted gasoline particulate filter can be used to measure the air pressure value P before the gas passes through the gasoline particulate filter at different exhaust gas flow rates 前 , and the air pressure value P after the gas passes through the gasoline particulate filter 后 . The measured air pressure value P 前 and the air pressure value P 后 are respectively used as the inputs of P 前理论 and P 后理论 to complete the theoretical air pressure calibration. Based on this, when the vehicle engine delivers gas to the gasoline particulate filter at different exhaust gas flow rates, the pressure drop of the gas before and after passing through the unsooted gasoline particulate filter can be determined, that is, (P 前理论 -P 后理论 ).

[0134] In one example, the soot accumulation state corresponding to the "pressure difference between the current air pressure and the preset air pressure" can be determined according to the pressure difference between the current air pressure and the preset air pressure, and the pre-calibrated pressure difference - soot accumulation state mapping data.

[0135] Furthermore, in one example, specifically, in the embodiments of the present application, when the air pressure detection component of the vehicle detects the current intake air pressure of the gasoline particulate filter, the vehicle can calculate the pressure difference between the current intake air pressure and the preset outlet air pressure according to the current intake air pressure and the preset outlet air pressure determined by the exhaust gas flow rate of the vehicle engine, and determine the soot accumulation state corresponding to the "pressure difference between the current air pressure and the preset air pressure" according to the pre-calibrated pressure difference - soot accumulation state mapping data.

[0136] Alternatively, when the air pressure detection component of the vehicle detects the current outlet air pressure of the gasoline particulate filter, the vehicle can calculate the pressure difference between the current outlet air pressure and the preset intake air pressure according to the current outlet air pressure and the preset intake air pressure determined by the exhaust gas flow rate of the vehicle engine, and determine the soot accumulation state corresponding to the "pressure difference between the current air pressure and the preset air pressure" according to the pre-calibrated pressure difference - soot accumulation state mapping data.

[0137] In this way, in the embodiments of the present application, the soot accumulation state of the gasoline particulate filter can be determined according to the current air pressure and the preset air pressure, thereby realizing a robust determination of the soot accumulation state of the gasoline particulate filter.

[0138] In some embodiments of the present application, the soot accumulation state is used to indicate whether the gasoline particulate filter needs to be regenerated.

[0139] Specifically, in the embodiments of the present application, the vehicle can determine whether the gasoline particulate filter needs to be regenerated at the current moment according to the current intake air pressure or the current exhaust air pressure of the gasoline particulate filter detected by the air pressure detection component, in combination with the preset air pressure determined by using the current exhaust gas flow of the vehicle engine.

[0140] It can be understood that when the particulate matter trapped and accumulated in the gasoline particulate filter increases, the resistance of the vehicle exhaust gas flowing through the gasoline particulate filter by the particulate matter in the gasoline particulate filter becomes greater and greater, and the pressure difference before and after the vehicle exhaust gas flows through the gasoline particulate filter becomes greater and greater. Furthermore, if there is a large amount of particulate matter accumulated in the gasoline particulate filter and it lasts for a long time, the exhaust back pressure will increase significantly, which will limit the power output of the engine, increase fuel consumption, and may cause damage to the gasoline particulate filter in severe cases, such as perforation, displacement, etc.

[0141] Therefore, when the pressure difference before and after the vehicle exhaust gas flows through the gasoline particulate filter reaches a threshold value, it can be considered that the resistance of the particulate matter accumulated inside the gasoline particulate filter to the vehicle exhaust gas is relatively large, so the gasoline particulate filter can be controlled to perform active regeneration.

[0142] In one example, the vehicle can adjust the operating parameters of the engine, such as delaying the ignition time, increasing the fuel injection amount, etc., to increase the exhaust gas temperature, thereby promoting the combustion of the particulate matter in the gasoline particulate filter to reduce the resistance of the particulate matter in the gasoline particulate filter to the vehicle exhaust gas.

[0143] In this way, in the embodiments of the present application, it is possible to determine whether the gasoline particulate filter needs to be regenerated according to the current air pressure and the preset air pressure, so as to realize the timely execution of the regeneration process of the gasoline particulate filter, thereby ensuring the stable operation of the vehicle exhaust gas treatment system.

[0144] Please refer to Figure 10 , in some embodiments of the present application, step 010 includes:

[0145] 0100: Determine the current particulate matter loading of the gasoline particulate filter according to the current air pressure and the preset air pressure;

[0146] 0101: Determine the carbon accumulation state according to the current particulate matter loading.

[0147] The processor in the embodiments of the present application is further configured to determine the current particulate matter loading of the gasoline particulate filter according to the current air pressure and the preset air pressure, and to determine the carbon accumulation state according to the current particulate matter loading.

[0148] Specifically, in the embodiments of the present application, the vehicle can determine the particulate matter loading of the gasoline particulate filter at the current moment, that is, the above-mentioned current particulate matter loading, according to the current intake air pressure or the current exhaust air pressure of the gasoline particulate filter detected by the air pressure detection component, in combination with the preset air pressure determined by using the current exhaust gas flow rate of the vehicle engine.

[0149] Further, the vehicle can determine whether the gasoline particulate filter needs to be regenerated at the current moment according to the current particulate matter loading of the gasoline particulate filter, or rather, determine the carbon accumulation state of the gasoline particulate filter at the current moment.

[0150] In one example, the vehicle can determine the current particulate matter loading of the gasoline particulate filter according to a pre-set program or function for implementing the particulate matter loading calculation algorithm, in combination with the current air pressure and the preset air pressure.

[0151] In this way, in the embodiments of the present application, the current particulate matter loading of the gasoline particulate filter can be determined according to the current air pressure and the preset air pressure, and whether the gasoline particulate filter needs to be regenerated can be determined according to the current particulate matter loading, thereby ensuring a robust determination of whether the gasoline particulate filter can be regenerated.

[0152] In some embodiments of the present application, when the current air pressure is the current intake air pressure, the preset air pressure is the preset exhaust air pressure, and when the current air pressure is the current exhaust air pressure, the preset air pressure is the preset intake air pressure. Furthermore, step 0100 includes:

[0153] Determine the current particulate matter loading according to the pressure difference between the current air pressure and the preset air pressure.

[0154] The processor in the embodiments of the present application is further configured to determine the current particulate matter loading according to the pressure difference between the current air pressure and the preset air pressure.

[0155] Specifically, in the embodiments of the present application, when the air pressure detection component detects the current intake air pressure of the gasoline particulate filter, the vehicle can calculate the pressure difference between the current intake air pressure and the preset exhaust air pressure according to the current intake air pressure and the preset exhaust air pressure determined by the exhaust gas flow rate of the vehicle engine, and determine the current particulate matter loading of the gasoline particulate filter according to the pressure difference.

[0156] Alternatively, when the air pressure detection component detects the current exhaust air pressure of the gasoline particulate filter, the vehicle can calculate the pressure difference between the current exhaust air pressure and the preset intake air pressure according to the current exhaust air pressure and the preset intake air pressure determined by the exhaust gas flow rate of the vehicle engine, and determine the current particulate matter loading of the gasoline particulate filter according to the pressure difference.

[0157] In one example, the vehicle can call the pre-calibrated pressure difference - particulate matter load mapping data to determine the particulate matter load corresponding to "the pressure difference between the current outlet air pressure and the preset inlet air pressure", which is the current particulate matter load in the embodiments of the present application.

[0158] In one example, the vehicle can call the pre-set carbon load model and input the pressure difference between the current outlet air pressure and the preset inlet air pressure into the carbon load model, thereby obtaining the carbon load calculation result output by the carbon load model, which is the current particulate matter load in the embodiments of the present application.

[0159] In this way, in the embodiments of the present application, the current particulate matter load of the gasoline particulate filter can be determined according to the pressure difference between the current air pressure and the preset air pressure, thereby realizing the robust determination of the current particulate matter load.

[0160] In some embodiments of the present application, step 0101 includes:

[0161] When the current particulate matter load is greater than or equal to the preset particulate matter load threshold, it is determined that the gasoline particulate filter needs to be regenerated; and / or,

[0162] When the current particulate matter load is less than the preset particulate matter load threshold, it is determined that the gasoline particulate filter does not need to be regenerated.

[0163] The processor in the embodiments of the present application is further configured to determine that the gasoline particulate filter needs to be regenerated when the current particulate matter load is greater than or equal to the preset particulate matter load threshold, and / or is configured to determine that the gasoline particulate filter does not need to be regenerated when the current particulate matter load is less than the preset particulate matter load threshold.

[0164] Specifically, in the embodiments of the present application, the vehicle can determine that the gasoline particulate filter has captured enough particulate matter in the past time when the current particulate matter load is greater than or equal to the preset particulate matter load threshold, and the quantity of particulate matter at the current moment can affect the particulate matter capture performance of the gasoline particulate filter to a certain extent. Furthermore, the vehicle can determine that the gasoline particulate filter at the current moment needs to be regenerated.

[0165] In addition, in the embodiments of the present application, when the current particulate matter load is less than the preset particulate matter load threshold, the vehicle determines that the gasoline particulate filter has not captured enough particulate matter in the past time, and the quantity of particulate matter at the current moment has not significantly affected the particulate matter capture performance of the gasoline particulate filter. Furthermore, the vehicle can determine that the gasoline particulate filter at the current moment does not need to be regenerated.

[0166] It can be understood that the specific size of the preset particulate matter loading threshold can be determined according to information such as vehicle model, engine parameters, and gasoline particulate filter specifications.

[0167] Thus, in the embodiments of the present application, it can be determined that the gasoline particulate filter can be regenerated when the current particulate matter loading is greater than or equal to the preset particulate matter loading threshold; and / or it can be determined that the gasoline particulate filter does not need to be regenerated when the current particulate matter loading is less than the preset particulate matter loading threshold, thereby ensuring a robust determination of the carbon accumulation state of the gasoline particulate filter.

[0168] In some embodiments of the present application, the vehicle control method further includes:

[0169] When the gasoline particulate filter can be regenerated, perform a regeneration process on the gasoline particulate filter.

[0170] The processor in the embodiments of the present application is further configured to perform a regeneration process on the gasoline particulate filter when the gasoline particulate filter needs to be regenerated.

[0171] Specifically, in the embodiments of the present application, when the vehicle determines that the gasoline particulate filter needs to be regenerated, the gasoline particulate filter can be regenerated.

[0172] In one example, the vehicle can adjust the operating parameters of the engine, such as delaying the ignition timing, increasing the fuel injection volume, etc., to increase the exhaust gas temperature, thereby promoting the combustion of particulate matter in the gasoline particulate filter to reduce the obstruction of the particulate matter in the gasoline particulate filter to the vehicle's exhaust gas, thereby realizing the regeneration process for the gasoline particulate filter.

[0173] Thus, in the embodiments of the present application, when the gasoline particulate filter can be regenerated, perform a regeneration process on the gasoline particulate filter, thereby ensuring the timely regeneration of the gasoline particulate filter.

[0174] To more clearly illustrate the process of "determining whether the gasoline particulate filter can be regenerated" in the embodiments of the present application, please refer to Figure 9 and Figure 11 , Figure 11 which is a schematic diagram of the vehicle control method in some embodiments of the present application, that is, as Figure 11 shown, in the embodiments of the present application, during the vehicle operation, the pressure P of the vehicle's exhaust gas flowing through the gasoline particulate filter is collected by the air pressure detection component 前 , and at the same time, the exhaust gas flow rate of the engine at the current moment is read.

[0175] Then, according to the current flow rate, retrieve the theoretically calibrated pressure P corresponding to the exhaust gas flow rate of the engine at the current moment after the vehicle's to-be-exhausted gas passes through the non-carbon-accumulated gasoline particulate filter. 后理论 , and based on P 前 and P 后理论 calculate the pressure drop P1 at the current moment, that is:

[0176] P1 = P 前 - P 后理论

[0177] Then, according to the pressure drop P1 and the carbon loading model, calculate the current carbon loading of the gasoline particulate filter at the current moment.

[0178] Next, determine the magnitude relationship between the current carbon loading and the preset target carbon loading. Among them, if the target carbon loading ≥ the target carbon loading, it indicates that the carbon accumulation amount in the gasoline particulate filter has reached the condition for activating the active regeneration function of the gasoline particulate filter, and active regeneration needs to be started. On the contrary, when the target carbon loading < the target carbon loading, it indicates that the carbon accumulation amount in the gasoline particulate filter has not reached the condition for activating the active regeneration function of the gasoline particulate filter, and the vehicle continues to drive normally.

[0179] In some embodiments of the present application, the carbon accumulation state is used to indicate the execution result of the regeneration treatment of the gasoline particulate filter.

[0180] Specifically, in the embodiments of the present application, the vehicle can determine the execution result after the last regeneration treatment of the gasoline particulate filter according to the current intake air pressure or the current outlet air pressure of the gasoline particulate filter detected by the air pressure detection component, in combination with the preset air pressure determined by using the current exhaust gas flow rate of the vehicle engine.

[0181] In one example, the execution results of the regeneration treatment of the gasoline particulate filter include two types, namely normal execution and abnormal execution.

[0182] Thus, in the embodiments of the present application, the execution effect of the regeneration treatment of the gasoline particulate filter can be determined according to the current air pressure and the preset air pressure, so that the timely monitoring of the regeneration treatment of the gasoline particulate filter can be realized, thereby ensuring the stable operation of the vehicle exhaust gas treatment system.

[0183] In some embodiments of the present application, step 010 includes:

[0184] After the regeneration treatment of the gasoline particulate filter, determine the carbon accumulation state according to the current air pressure and the preset air pressure.

[0185] The processor in the embodiments of the present application is further configured to determine the carbon accumulation state according to the current air pressure and the preset air pressure after the regeneration treatment of the gasoline particulate filter.

[0186] Specifically, to ensure the effectiveness and reliability of the execution effect of the regeneration process, in the embodiment of the present application, after the vehicle performs a regeneration process on the gasoline particulate filter, it can determine the execution result after the last regeneration process of the gasoline particulate filter according to the current intake air pressure or the current exhaust air pressure of the gasoline particulate filter detected by the air pressure detection component, in combination with the preset air pressure determined by using the current exhaust gas flow of the vehicle engine.

[0187] Thus, in the embodiment of the present application, after performing a regeneration process on the gasoline particulate filter, the execution result of the regeneration process of the gasoline particulate filter can be determined, thereby ensuring the effectiveness and reliability of the execution result of the regeneration process.

[0188] Please refer to Figure 12 , in some embodiments of the present application, the preset air pressure includes a preset intake air pressure and a preset exhaust air pressure. Furthermore, step 010 includes:

[0189] 0102: Determine a first air pressure difference according to the current air pressure and one of the preset intake air pressure and the preset exhaust air pressure;

[0190] 0103: Determine a second air pressure difference according to the preset intake air pressure and the preset exhaust air pressure;

[0191] 0104: Determine the carbon accumulation state according to the first air pressure difference and the second air pressure difference.

[0192] The processor in the embodiment of the present application is further configured to determine a first air pressure difference according to the current air pressure and one of the preset intake air pressure and the preset exhaust air pressure, determine a second air pressure difference according to the preset intake air pressure and the preset exhaust air pressure, and determine the carbon accumulation state according to the first air pressure difference and the second air pressure difference.

[0193] Specifically, in the embodiment of the present application, when the air pressure detection component detects the current intake air pressure of the gasoline particulate filter, the vehicle can calculate the first air pressure difference between the current intake air pressure and the preset exhaust air pressure in combination with the preset exhaust air pressure and the preset exhaust air pressure determined by the exhaust gas flow of the vehicle engine. Alternatively, when the air pressure detection component detects the current exhaust air pressure of the gasoline particulate filter, the vehicle can calculate the first air pressure difference between the current exhaust air pressure and the preset intake air pressure in combination with the preset exhaust air pressure and the preset exhaust air pressure determined by the exhaust gas flow of the vehicle engine.

[0194] In addition, the vehicle can calculate the second air pressure difference between the preset intake air pressure and the preset exhaust air pressure to represent the air pressure difference before and after the vehicle's exhaust gas to be discharged flows through the gasoline particulate filter when the regeneration process of the gasoline particulate filter is executed normally.

[0195] Thus, the vehicle can determine the regeneration process result of the gasoline particulate filter according to the first air pressure difference and the second air pressure difference.

[0196] In one example, when the difference between the first air pressure difference and the second air pressure difference is less than or equal to a preset threshold value, the regeneration process of the gasoline particulate filter is normal; otherwise, it is abnormal.

[0197] Thus, in the embodiment of the present application, the first air pressure difference can be determined according to the current air pressure and one of the preset intake air pressure and the preset outlet air pressure, the second air pressure difference can be determined according to the preset intake air pressure and the preset outlet air pressure, and the regeneration process result of the gasoline particulate filter can be determined according to the first air pressure difference and the second air pressure difference, thereby ensuring the robust determination of the execution result of the regeneration process of the gasoline particulate filter.

[0198] In some embodiments of the present application, step 0104 includes:

[0199] When the ratio of the first air pressure difference to the second air pressure difference is greater than or equal to a preset ratio threshold value, it is determined that the regeneration process of the gasoline particulate filter is executed normally; and / or,

[0200] When the ratio of the first air pressure difference to the second air pressure difference is less than the preset ratio threshold value, it is determined that the regeneration process of the gasoline particulate filter is executed abnormally.

[0201] Specifically, in the embodiment of the present application, the vehicle can determine whether the regeneration process of the gasoline particulate filter is executed normally or abnormally according to the magnitude relationship between the ratio of the first air pressure difference to the second air pressure difference and the preset ratio threshold value.

[0202] Specifically, when the ratio of the first air pressure difference to the second air pressure difference is greater than or equal to the preset ratio threshold value, the vehicle can determine that the regeneration process of the gasoline particulate filter is executed normally.

[0203] And when the ratio of the first air pressure difference to the second air pressure difference is less than the preset ratio threshold value, the vehicle can determine that the regeneration process of the gasoline particulate filter is executed abnormally.

[0204] In one example, the preset ratio threshold value is 90%, or 0.9.

[0205] In one example, the value range of the preset ratio threshold value is [0.9, 1], or rather, the value range of the preset ratio threshold value is [90%, 100%].

[0206] Thus, in the embodiment of the present application, when the ratio of the first air pressure difference to the second air pressure difference is greater than or equal to the preset ratio threshold value, it can be determined that the regeneration process of the gasoline particulate filter is executed normally, and / or when the ratio of the first air pressure difference to the second air pressure difference is less than the preset ratio threshold value, it can be determined that the regeneration process of the gasoline particulate filter is executed abnormally, thereby ensuring the reliable determination of the execution result of the regeneration process of the gasoline particulate filter.

[0207] In some embodiments of the present application, the vehicle control method further includes:

[0208] In the case where the regeneration process of the gasoline particulate filter is executed abnormally, a preset prompt message is fed back and / or the gasoline particulate filter is regenerated.

[0209] The processor in the embodiments of the present application is further configured to, in the case where the regeneration process of the gasoline particulate filter is executed abnormally, feed back a preset prompt message and / or regenerate the gasoline particulate filter.

[0210] Specifically, in the embodiments of the present application, when the regeneration process of the gasoline particulate filter is executed abnormally, the vehicle can feed back a preset prompt message to the user, the vehicle repair shop, or a server communicatively connected to the vehicle, etc., to prompt that the regeneration process of the gasoline particulate filter in the vehicle is executed abnormally. And / or, when the regeneration process of the gasoline particulate filter is executed abnormally, the vehicle also controls the gasoline particulate filter to perform a regeneration process again to attempt to restore the particulate trapping performance of the gasoline particulate filter.

[0211] Thus, in the embodiments of the present application, a preset prompt message can be fed back and / or the gasoline particulate filter can be regenerated in the case where the regeneration process of the gasoline particulate filter is executed abnormally, thereby ensuring the stable operation of the vehicle.

[0212] For a clearer description of the specific execution logic of the process of "determining the execution result of the regeneration process of the gasoline particulate filter" in the embodiments of the present application, please refer to Figure 13 , Figure 13 which is a schematic flow chart of the vehicle control method in some embodiments of the present application, that is, as Figure 13 shown, in the embodiments of the present application, the pressure P of the vehicle's exhaust gas to be discharged before flowing through the gasoline particulate filter is collected by a pressure detection component 前 , and the exhaust gas flow rate of the engine at the current moment is read simultaneously. This pressure is the actual pressure before the GPF at the current flow rate.

[0213] Then, according to the current flow rate, the theoretical pressure P of the vehicle's exhaust gas to be discharged after flowing through the uncarbonized gasoline particulate filter corresponding to the exhaust gas flow rate of the engine at the current moment, which is pre-calibrated, is retrieved 后理论 , and based on P 前 and P 后理论 the pressure drop P2 at the current moment is calculated, that is:

[0214] P2 = P 前 - P 后理论

[0215] And, according to the current flow rate, retrieve the theoretically calibrated pressure P corresponding to the exhaust gas flow rate of the engine at the current moment before the vehicle's exhaust gas flows through the unsooted gasoline particulate filter 前理论 , and calculate P 前理论 and P 后理论 The pressure difference P3 to characterize the pressure difference before and after the vehicle's exhaust gas flows through the unsooted gasoline particulate filter under ideal conditions, that is:

[0216] P3 = P 前理论 - P 后理论

[0217] Next, calculate the regeneration degree X, that is:

[0218] X = P3 / P2

[0219] Finally, according to the magnitudes of X and n, determine the execution effect of the regeneration treatment of the vehicle's gasoline particulate filter at that moment. Among them, n ranges from 90% to 100% according to the calibration strategy and changes in the gasoline particulate filter product.

[0220] If X ≥ n, the regeneration treatment is successfully executed, indicating that the pressure difference P2 after the regeneration treatment of the gasoline particulate filter is close to the pressure difference P3 before and after the vehicle's exhaust gas flows through the unsooted gasoline particulate filter under theoretical conditions.

[0221] On the contrary, if X < n, that is, the regeneration treatment is executed abnormally, indicating that the pressure difference P2 after the regeneration treatment of the gasoline particulate filter is far from the pressure difference P3 before and after the vehicle's exhaust gas flows through the unsooted gasoline particulate filter under theoretical conditions, and a fault can be reported accordingly.
