[0029] As described in the background section, there is a problem in the prior art where vehicles cannot successfully regenerate. To solve the above-mentioned technical problem, embodiments of this application provide a regenerative exhaust gas processor, its control method, and a vehicle.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] This application provides a renewable exhaust gas processor, such as... Figure 1 As shown, the renewable exhaust gas processor includes:

[0032] The exhaust gas purification structure 10 includes a catalytic converter 11 and a particulate filter (Diesel Particulate Filter, abbreviated as DPF) 12. The input end of the particulate filter 12 is connected to the output end of the catalytic converter 11. The exhaust gas purification structure 10 is used to purify the input exhaust gas and output the purified exhaust gas.

[0033] Specifically, the catalytic converter 11 is a device that uses a catalyst to accelerate the rate of a chemical reaction, converting harmful gases into harmless gases. Specifically, the catalytic converter can be a Diesel Oxidation Catalyst (DOC), used to convert carbon monoxide and hydrocarbons in engine exhaust into water and carbon dioxide through an oxidation reaction. The particulate matter filter 12 is a device used to capture particulate matter (such as dust, soot, particles, etc.) in the atmosphere. It mainly uses physical or chemical methods to capture and fix the particulate matter on its surface, thereby purifying the air.

[0034] The heat insulation shell 14 has an input end connected to the output end of the exhaust gas purification structure 10, and the output end of the heat insulation shell 14 is connected to the external environment.

[0035] Specifically, the insulation shell has an accommodating space.

[0036] The containment structure 15 is located inside the heat-insulating shell 14. There is a tail gas flow channel 16 between the heat-insulating shell 14 and the containment structure 15. The output end of the containment structure 15 is connected to the input end of the catalytic converter 11. The containment structure 15 contains the target gas. During the process of the purified tail gas being discharged to the external environment through the tail gas flow channel 16, the purified tail gas heats the target gas in the containment structure 15.

[0037] Specifically, the receiving structure 15 is located within the receiving space of the insulation shell 14, with a gap between them, thereby forming the exhaust gas flow channel 16. The input end of the insulation shell 14 is also the input end of the exhaust gas flow channel 16. Therefore, the output end of the exhaust gas purification structure 10 is connected to the input end of the exhaust gas flow channel 16. The target gas can be any type of gas with combustion-supporting function, and can be a single gas or a mixture of gases, such as oxygen or air as the target gas.

[0038] In the above embodiment, the exhaust gas processor includes an exhaust gas purification structure comprising a catalytic converter and a particulate matter trap connected in sequence. The housing structure is located inside the insulation shell, and an exhaust gas flow channel is formed between the two. The output end of the housing structure is connected to the input end of the catalytic converter, and the output end of the exhaust gas purification structure is connected to the exhaust gas flow channel. The output end of the exhaust gas purification structure is connected to the external environment. After being purified by the exhaust gas purification structure, the exhaust gas can enter the exhaust gas flow channel and then be discharged to the atmosphere through the exhaust gas flow channel, thereby heating the target gas in the housing structure. This application sets up a receiving structure and an insulating shell to enclose the receiving structure at the output end of the exhaust gas purification structure. The exhaust gas purified by the exhaust gas purification structure enters the insulating shell, heating the target gas in the receiving structure. The heated target gas is then delivered to the input end of the catalytic converter to increase the temperature and gas input flow rate at the input end of the catalytic converter, ensuring that the input temperature and gas input flow rate of the catalytic converter meet the requirements, thereby meeting the requirements of the vehicle's on-road regeneration conditions. On-road regeneration is achieved by utilizing the higher temperature exhaust gas, avoiding the problem of the vehicle failing to successfully regenerate on-road, causing the particulate matter filter to overload, resulting in low engine efficiency or even abnormal operation. At the same time, it improves the exhaust gas utilization rate and reduces the maintenance cost of on-road regeneration.

[0039] In this context, "driving regeneration" refers to the process where particulate matter accumulates in the DPF (Discharge Propeller) during normal vehicle operation. As the amount of accumulated particulate matter gradually increases, it leads to increased exhaust resistance and reduced engine efficiency. To maintain the normal operating condition of the engine, the DPF needs to undergo periodic regeneration to remove the accumulated particulate matter. The inventors discovered that vehicles fail to successfully perform driving regeneration primarily because the exhaust temperature is insufficient to ignite the catalytic converter; additionally, insufficient exhaust flow may also be a cause, as it may not provide enough oxygen for the catalytic converter to ignite.

[0040] The solution described in this application utilizes purified exhaust gas to heat the target gas, and then introduces the heated target gas into the catalytic converter through the input end of the catalytic converter. This not only increases the temperature of the gas entering the catalytic converter but also increases the flow rate of the gas entering the catalytic converter, thereby effectively solving the problem of vehicles being unable to successfully regenerate due to the aforementioned reasons.

[0041] The containing structure described in this application can specifically be a bottle-shaped structure, a can-shaped structure, a cylinder-shaped structure, or other structures. The shape of the heat-insulating shell can be adapted to the containing structure; for example, if the containing structure is a gas cylinder, the heat-insulating shell is also a bottle-shaped structure.

[0042] To achieve better insulation performance, the insulation shell may specifically include an inner insulation cylinder, an outer insulation cylinder fitted over the inner insulation cylinder, and an insulation cavity partition located between the inner and outer insulation cylinders. The inner insulation cylinder has a accommodating space to house the accommodating structure. Furthermore, to ensure more uniform heating, none of the outer walls of the accommodating structure contact the inner wall of the inner insulation cylinder, allowing the exhaust gas flow channel to enclose the accommodating structure, thus enabling the gas entering the exhaust gas flow channel to heat the accommodating structure more evenly.

[0043] In one exemplary embodiment, such as Figure 2 As shown, the renewable exhaust gas processor further includes a valve structure 13, which includes three ports. The output end of the exhaust gas purification structure 10 is connected to the external environment through the first and second ports of the valve structure 13, and the output end of the exhaust gas purification structure 10 is connected to the input end of the insulation shell 14 through the first and third ports of the valve structure 13. In this embodiment, by setting the valve structure between the exhaust gas purification structure and the insulation shell, when the exhaust gas temperature is high, the opening and closing of the three-port valve structure can control the exhaust gas purified by the exhaust gas purification structure to enter the insulation shell, thereby heating the target gas in the containment structure. The heated target gas is then delivered to the input end of the catalytic converter, further ensuring that the vehicle can successfully regenerate while driving, and further avoiding the problem of the particulate matter filter being overloaded due to the vehicle's inability to successfully regenerate, resulting in low engine efficiency or even abnormal operation. In addition, when the exhaust gas temperature is low and cannot heat the target gas, the opening and closing of the three-port valve structure can open the passage from the exhaust gas purification structure through the valve structure to the atmosphere, and close the passage from the exhaust gas purification structure through the valve structure and the insulation shell to the atmosphere, so that the lower temperature exhaust gas is directly discharged to the external environment after purification without affecting the target gas in the containment structure.

[0044] Specifically, the valve structure 13 may include a three-way valve. When the output end of the particulate matter collector 12 is the output end of the exhaust gas purification structure 10, the output end of the particulate matter collector 12 is connected to the external environment through the first port and the second port of the valve structure 13 in sequence.

[0045] In one of the alternative solutions, such as Figure 2As shown, the regenerative exhaust gas processor further includes a pump assembly 22 located in the communication channel between the output end of the housing structure 15 and the input end of the catalytic converter 11. The pump assembly 22 is used to pump the target gas in the housing structure 15 into the catalytic converter 11. By providing the target gas with the power to flow to the catalytic converter through the pump assembly, it is further ensured that the target gas can smoothly enter the catalytic converter through the input end of the catalytic converter.

[0046] According to another exemplary embodiment of this application, such as Figure 2 As shown, the regenerative exhaust gas processor further includes a heating structure 17 located in the communication channel between the output end of the receiving structure 15 and the input end of the catalytic converter 11. The heating structure 17 is used to heat the target gas in the communication channel. When the temperature of the heated target gas cannot meet the input temperature requirements of the catalytic converter, the heating structure heats the target gas, ensuring a higher temperature at the input end of the catalytic converter. This further guarantees successful vehicle regeneration and avoids problems such as low engine efficiency or even abnormal operation caused by unsuccessful regeneration.

[0047] Specifically, the heating structure can be any suitable type of heater, such as a heating grid, heating coil, etc.

[0048] In some other embodiments, such as Figure 1 and Figure 2 As shown, the renewable exhaust gas processor further includes at least the following components:

[0049] One-way venting valve 18, one end of which is connected to the receiving structure 15 and the other end of which is connected to the external environment. When the pressure in the receiving structure 15 is greater than the preset pressure value, the one-way venting valve 18 is used to discharge the target gas in the receiving structure 15 to the external environment.

[0050] Specifically, the one-way venting valve can be a one-way mechanical valve that automatically opens to release part of the target gas when the pressure is greater than the preset pressure value; the one-way venting valve can also be a one-way electronic valve that is switched on and off by control.

[0051] The first temperature sensor 19 is located at the input end of the catalytic converter 11 and is used to collect the temperature value at the input end of the catalytic converter 11.

[0052] The second temperature sensor 20 is located at the output end of the containment structure 15 and is used to collect the temperature value of the target gas in the containment structure 15.

[0053] In the embodiment, the gas pressure in the containment structure is adjusted by the one-way venting valve to avoid excessive pressure in the containment structure caused by heating the purified exhaust gas, thus ensuring the safe operation of the regenerative exhaust gas processor. The input temperature of the catalytic converter is collected by the first temperature sensor, and the temperature value of the target gas in the containment structure is collected by the second temperature sensor. The valve structure and the heating structure can be accurately controlled by these two temperatures.

[0054] Specifically, such as Figure 1 and Figure 2 As shown, the exhaust gas purification structure further includes a Selective Catalytic Reduction (SCR) structure 21. The input end of the SCR structure 21 is connected to the output end of the particulate matter trap 12, and the output end of the SCR structure 21 is the output end of the exhaust gas purification structure 10. The SCR structure is used to selectively react with NO in the exhaust gas using a reducing agent under the action of a catalyst. x The reaction produces non-toxic and pollution-free nitrogen and water, further purifying the exhaust gas.

[0055] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 3 This is a hardware structure block diagram of a mobile terminal for a control method of a renewable exhaust gas processor according to an embodiment of the present invention. Figure 3 As shown, a mobile terminal may include one or more ( Figure 3 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 3 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal. For example, the mobile terminal may also include components that are larger than... Figure 3 The more or fewer components shown, or having the same Figure 3 The different configurations shown.

[0056] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the control method of the renewable exhaust gas processor in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the method described. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof. The transmission device 106 is used to receive or send data via a network. Specific examples of such networks may include wireless networks provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0057] This embodiment provides a control method for a renewable exhaust gas processor that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0058] Figure 4 This is a flowchart generated according to the control method of the regenerative exhaust gas processor according to the embodiments of this application, wherein the specific structure of the regenerative exhaust gas processor is as follows: Figure 1 As shown. Figure 4 As shown, the method includes the following steps:

[0059] Step S201: When the temperature at the input end of the catalytic converter is greater than the first temperature threshold, the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell is controlled to be opened, so that the exhaust gas enters the insulation shell through the exhaust gas purification structure, so as to heat the target gas in the containment structure and then discharge it to the external environment through the insulation shell.

[0060] Specifically, the temperature at the input end of the catalytic converter is the same as the temperature of the input exhaust gas.

[0061] Step S202: When the temperature at the input end of the catalytic converter is less than or equal to the second temperature threshold and the temperature at the output end of the containment structure is greater than the third temperature threshold, at least the output end of the containment structure is controlled to open, so that the heated target gas enters the catalytic converter through the input end of the catalytic converter, and the first temperature threshold and the third temperature threshold are greater than the second temperature threshold.

[0062] Specifically, the temperature at the output end of the containment structure is the temperature of the target gas. When the input temperature of the catalytic converter is low and the temperature of the target gas is high, vehicle regeneration may fail. In this case, controlling the output end of the containment structure to open allows the high-temperature target gas in the containment structure to enter the catalytic converter through the input end, thus heating the exhaust gas at the input end of the catalytic converter and increasing the oxygen content of the exhaust gas. This application does not limit the relationship between the first temperature threshold and the third temperature threshold. The first temperature threshold can be greater than the third temperature threshold, or it can be equal to the third temperature threshold.

[0063] In the above embodiment, when the temperature at the input end of the catalytic converter is greater than a first temperature threshold, the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell is first opened, so that the exhaust gas enters the insulation shell through the exhaust gas purification structure and is then discharged to the external environment, thereby heating the target gas in the containment structure; then, when the temperature at the input end of the catalytic converter is less than or equal to a second temperature threshold and the temperature at the output end of the containment structure is greater than a third temperature threshold, at least the output end of the containment structure is opened, so that the heated target gas enters the catalytic converter through the input end of the catalytic converter. This application addresses the issue of exhaust gas temperature. When the exhaust gas temperature is high, it controls the connection of the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell, allowing the purified exhaust gas to enter the insulation shell and heat the target gas within the structure. When the input end temperature of the catalytic converter is low and the target gas temperature is high, the target gas is delivered to the input end of the catalytic converter to increase the temperature and gas flow rate at the catalytic converter input end. This ensures that the input temperature and gas flow rate of the catalytic converter meet the requirements, thereby satisfying the vehicle's on-road regeneration requirements. By utilizing the high-temperature exhaust gas, on-road regeneration is achieved, avoiding the problem of vehicle failure to successfully regenerate on-road, causing particulate matter filter overload, resulting in low engine efficiency or even abnormal operation. At the same time, it improves exhaust gas utilization and reduces the maintenance cost of on-road regeneration.

[0064] According to some exemplary embodiments of this application, such as Figure 2As shown, the renewable exhaust gas processor also includes a valve structure 13, which has three ports. The output end of the exhaust gas purification structure 10 is connected to the external environment through the first and second ports of the valve structure 13. The output end of the exhaust gas purification structure 10 is connected to the input end of the insulation shell 14 through the first and third ports of the valve structure 13. Controlling the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell to open, so that the exhaust gas enters the insulation shell through the exhaust gas purification structure, includes: controlling the first and third ports of the valve structure to open and controlling the second port of the valve structure to close, so that the exhaust gas enters the insulation shell through the exhaust gas purification structure and the valve structure. In this embodiment, a valve structure is provided between the exhaust gas purification structure and the insulation shell. When the first and third ports of the valve structure are open and the second port is closed, the passage from the exhaust gas purification structure, through the valve structure and the insulation shell to the atmosphere is open, and the passage from the exhaust gas purification structure, through the valve structure to the atmosphere is closed. When the exhaust gas temperature is high, the valve structure controls the opening and closing of the exhaust gas, allowing it to pass through the exhaust gas purification structure and the valve structure and then enter the exhaust gas flow channel between the insulation shell and the housing structure in the insulation shell. This heats the target gas in the housing structure, further ensuring that the vehicle can successfully regenerate while driving, and further preventing the vehicle from failing to regenerate while driving, causing the particulate matter filter to overload, resulting in low engine efficiency or even abnormal operation.

[0065] In one alternative, such as Figure 2 As shown, the regenerative exhaust gas processor also includes a pump assembly 22, located in the communication channel between the output end of the containment structure 15 and the input end of the catalytic converter 11. The pump assembly 22 is used to pump the target gas in the containment structure 15 into the catalytic converter 11, at least controlling the output end of the containment structure to open, including controlling the output end of the containment structure to open and controlling the pump assembly to start working, so as to pump the heated target gas into the catalytic converter. Simultaneously opening the output end of the containment structure and activating the pump assembly to provide the target gas with the power to flow to the catalytic converter further ensures that the target gas can smoothly enter the catalytic converter through the input end.

[0066] Specifically, the method further includes: when the temperature at the input end of the catalytic converter is less than or equal to the first temperature threshold, controlling the first and second ports of the valve structure to open and the third port of the valve structure to close, so that the exhaust gas is discharged to the external environment through the exhaust gas purification structure and the valve structure. In this embodiment, when the exhaust gas temperature is low, it cannot heat the target gas. At this time, controlling the first and second ports of the valve structure to open and the third port to close opens the passage from the exhaust gas purification structure and through the valve structure to the atmosphere, and closes the passage from the exhaust gas purification structure and through the valve structure and the insulation shell to the atmosphere. This allows the low-temperature exhaust gas to be directly discharged to the external environment after purification without affecting the target gas in the containment structure.

[0067] In this embodiment, as Figure 2 As shown, the regenerative exhaust gas processor further includes a heating structure 17 located in the communication channel between the output end of the housing structure 15 and the input end of the catalytic converter 11. The heating structure 17 is used to heat the target gas in the communication channel. The method further includes: when the temperature at the input end of the catalytic converter is less than or equal to a first temperature threshold and the temperature at the output end of the housing structure is less than or equal to a third temperature threshold, controlling the heating structure to turn on to heat the exhaust gas and / or the target gas at the input end of the catalytic converter. In this embodiment, when the exhaust gas temperature is low and the target gas temperature is also low, the heating structure heats the exhaust gas and / or the target gas at the input end of the catalytic converter to increase the temperature and gas input flow rate at the input end of the catalytic converter, ensuring that the input temperature and gas input flow rate of the catalytic converter meet the requirements. This further ensures successful vehicle regeneration and avoids the problem of vehicle failure to successfully regenerate, causing particulate matter filter overload, resulting in low engine efficiency or even abnormal operation.

[0068] Specifically, when the temperature at the input end of the catalytic converter is less than or equal to the first temperature threshold and the temperature at the output end of the containment structure is less than or equal to the third temperature threshold, only the heating structure can be controlled to open, or the output end of the containment structure can be controlled to open in addition to controlling the heating structure to open.

[0069] In addition, the renewable exhaust gas processor further includes: a gas flow sensor located at the input end of the catalytic converter and on the side of the housing structure away from the catalytic converter where the housing structure is connected to the input end of the catalytic converter. The gas flow sensor is used to collect the gas flow rate at the input end of the catalytic converter. The method further includes: controlling the output end of the housing structure to open when the gas flow rate at the input end of the catalytic converter is less than a predetermined flow rate.

[0070] Controlling the opening of the output end of the containment structure when the gas flow rate at the input end of the catalytic converter is less than a predetermined flow rate includes: controlling the opening of the output end of the containment structure when the gas flow rate at the input end of the catalytic converter is less than a predetermined flow rate and the temperature at the output end of the containment structure is greater than a third temperature threshold; and controlling the opening of the output end of the containment structure and the heating structure when the gas flow rate at the input end of the catalytic converter is less than a predetermined flow rate and the temperature at the output end of the containment structure is less than or equal to the third temperature threshold.

[0071] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the control method of the renewable exhaust gas processor of this application will be described in detail below with reference to specific embodiments.

[0072] This embodiment relates to a specific control method for a renewable exhaust gas processor, wherein the renewable exhaust gas processor is as follows: Figure 2 As shown, Figure 5 As shown, the control method includes the following steps:

[0073] Step S1: When the vehicle is running at an exhaust gas temperature greater than the preset temperature value 1, the exhaust gas enters the outer layer of the containment structure (i.e., the exhaust gas flow channel) through the valve structure to heat the gas inside the containment structure; when the vehicle is running at an exhaust gas temperature less than or equal to the preset temperature value 1, the exhaust gas is directly discharged into the atmosphere through the valve structure; the outer layer of the containment structure is made of heat insulation material, which can ensure that the gas temperature inside the containment structure is at a higher temperature.

[0074] Step S2: When the vehicle starts regeneration while driving, if the regeneration conditions are met, the strategy will not intervene and normal regeneration will proceed. The exhaust gas will pass through the outer layer of the containment structure to heat the containment structure. When the pressure inside the containment structure is greater than the preset pressure value, the gas will be discharged through the one-way vent valve.

[0075] Step S3: When the vehicle's exhaust gas temperature is less than or equal to the preset temperature value 2 and the exhaust gas flow rate is less than or equal to the preset flow rate value due to idling or deceleration, the pump unit will work to introduce the high-temperature gas in the containment structure into the DOC input terminal to maintain the temperature and exhaust gas volume required for regeneration.

[0076] Step S4: When the vehicle is in a low-temperature condition for a long time and the gas temperature inside the containment structure is less than or equal to the preset temperature value 2, the heating structure in front of DOC will work to ensure that the gas temperature meets the preset temperature value 1 requirement.

[0077] Step S5: Based on the above operations, DOC can achieve vehicle regeneration under any operating conditions.

[0078] The method implements closed-loop control based on temperature to determine whether to pump air, which can effectively solve the problem of vehicles failing to regenerate successfully under urban conditions and avoid DPF overload.

[0079] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0080] This application also provides a control device for a renewable exhaust gas processor. It should be noted that the control device for the renewable exhaust gas processor in this application can be used to execute the control method for a renewable exhaust gas processor provided in this application. This device is used to implement the embodiments and preferred embodiments described herein; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0081] The control device for the renewable exhaust gas processor provided in the embodiments of this application will be described below.

[0082] Figure 6 This is a schematic diagram of a control device for a renewable exhaust gas processor according to an embodiment of this application, wherein the specific structure of the renewable exhaust gas processor is as follows: Figure 1 As shown. Figure 6 As shown, the device includes:

[0083] The first control unit 100 is used to control the pipeline from the output end of the exhaust gas purification structure to the input end of the heat insulation shell to be opened when the temperature at the input end of the catalytic converter is greater than the first temperature threshold, so that the exhaust gas enters the heat insulation shell through the exhaust gas purification structure, so as to heat the target gas in the containment structure and then discharge it to the external environment through the heat insulation shell.

[0084] Specifically, the temperature at the input end of the catalytic converter is the same as the temperature of the input exhaust gas.

[0085] The second control unit 200 is configured to, when the temperature at the input end of the catalytic converter is less than or equal to a second temperature threshold and the temperature at the output end of the containment structure is greater than a third temperature threshold, at least control the output end of the containment structure to open, so that the heated target gas enters the catalytic converter through the input end of the catalytic converter, wherein the first temperature threshold and the third temperature threshold are greater than the second temperature threshold.

[0086] Specifically, the temperature at the output end of the containment structure is the temperature of the target gas. When the input temperature of the catalytic converter is low and the temperature of the target gas is high, vehicle regeneration may fail. In this case, controlling the output end of the containment structure to open allows the high-temperature target gas in the containment structure to enter the catalytic converter through the input end, thus heating the exhaust gas at the input end of the catalytic converter and increasing the oxygen content of the exhaust gas. This application does not limit the relationship between the first temperature threshold and the third temperature threshold. The first temperature threshold can be greater than the third temperature threshold, or it can be equal to the third temperature threshold.

[0087] In the above embodiment, when the temperature at the input end of the catalytic converter is greater than a first temperature threshold, the first control unit controls the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell to be opened, so that the exhaust gas enters the insulation shell through the exhaust gas purification structure and is then discharged to the external environment, thereby heating the target gas in the containment structure; when the temperature at the input end of the catalytic converter is less than or equal to a second temperature threshold and the temperature at the output end of the containment structure is greater than a third temperature threshold, the second control unit controls at least the output end of the containment structure to be opened, so that the heated target gas enters the catalytic converter through the input end of the catalytic converter. This application addresses the issue of exhaust gas temperature. When the exhaust gas temperature is high, it controls the connection of the pipeline from the output end of the exhaust gas purification structure to the input end of the insulation shell, allowing the purified exhaust gas to enter the insulation shell and heat the target gas within the structure. When the input end temperature of the catalytic converter is low and the target gas temperature is high, the target gas is delivered to the input end of the catalytic converter to increase the temperature and gas flow rate at the catalytic converter input end. This ensures that the input temperature and gas flow rate of the catalytic converter meet the requirements, thereby satisfying the vehicle's on-road regeneration requirements. By utilizing the high-temperature exhaust gas, on-road regeneration is achieved, avoiding the problem of vehicle failure to successfully regenerate on-road, causing particulate matter filter overload, resulting in low engine efficiency or even abnormal operation. At the same time, it improves exhaust gas utilization and reduces the maintenance cost of on-road regeneration.

[0088] The control device for the renewable exhaust gas processor includes a processor and a memory. The first control unit and the second control unit, etc., are all stored as program units in the memory, and the processor executes the program units stored in the memory to achieve the corresponding functions. All modules are located in the same processor; alternatively, the modules may be located in different processors in any combination.

[0089] The processor contains a kernel, which retrieves the corresponding program units from memory. One or more kernels can be configured, and adjusting kernel parameters can at least address the problem of vehicles failing to regenerate successfully in existing technologies.

[0090] The memory may include non-permanent memory in computer-readable media, such as random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
