Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a vehicle exhaust gas treatment system, method, device, equipment and medium. Background Art

[0002] In order to purify vehicle exhaust gas and reduce the environmental pollution caused by vehicle exhaust gas, a three-way catalytic converter and a particulate trap for treating vehicle exhaust gas are generally provided on a vehicle. The three-way catalytic converter can purify harmful gases in vehicle exhaust gas. The particulate trap can capture particulate matter in vehicle exhaust gas.

[0003] In related technologies, vehicle exhaust gas treatment solutions usually arrange the three-way catalytic converter and the particulate trap on the vehicle in a fixed layout, and treat the vehicle exhaust gas through the three-way catalytic converter and the particulate trap. The layout is a close-coupled type or a rear-mounted type. The close-coupled type is to couple the three-way catalytic converter and the particulate trap together and install them behind the engine exhaust manifold of the vehicle. The rear-mounted type is to install the three-way catalytic converter behind the engine exhaust manifold of the vehicle, and then set the particulate trap at a position behind the three-way catalytic converter and far from the engine exhaust manifold.

[0004] According to the close-coupled type setting, the particulate trap is long-term close to the engine exhaust manifold, which will increase the exhaust back pressure of the engine, affect the power performance and fuel economy of the engine, and there is a risk of ablation of the particulate trap. According to the rear-mounted type setting, the particulate trap is long-term far from the engine exhaust manifold, the particulate trap is prone to carbon deposition, and the difficulty of the regeneration process of the particulate trap is increased. The vehicle exhaust gas treatment solutions in related technologies only arrange the three-way catalytic converter and the particulate trap on the vehicle in a fixed layout, so that the particulate trap is long-term close to or far from the engine exhaust manifold, affecting the working performance of the engine or the particulate trap.

Their structures and functions will be described below.

[0036] Among them, the engine exhaust manifold of the vehicle, the three-way catalytic converter 102, and the front-back moving mechanism 104 are sequentially arranged at intervals in the front-back direction of the vehicle. The particulate trap 103 is drivingly connected to the front-back moving mechanism 104 and can be driven by the front-back moving mechanism 104 to move in the front-back direction of the vehicle to a set position.

[0037] The three-way catalytic converter 102 is used to purify the exhaust gas discharged from the engine exhaust manifold.

[0038] The particulate trap 103 is used to capture particulate matter in the exhaust gas discharged from the engine exhaust manifold.

[0039] The control module 105 is configured to regularly obtain the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap 103; determine the target set position corresponding to the particulate trap 103 according to the current pressure information and the current temperature information; and send the identification information of the target set position to the front-back moving mechanism 104.

[0041] Optionally, the vehicle is a vehicle that needs to treat vehicle exhaust. The vehicle discharges exhaust through the engine exhaust manifold. The engine exhaust manifold, the three-way catalytic converter 102, and the front-back moving mechanism 104 of the vehicle are sequentially arranged at intervals in the front-back direction of the vehicle. The three-way catalytic converter 102 is arranged behind the engine exhaust manifold, and the front-back moving mechanism 104 is arranged behind the three-way catalytic converter 102. The intervals between the engine exhaust manifold, the three-way catalytic converter 102, and the front-back moving mechanism 104 can be set according to service requirements. The front, back, etc. indicated in the embodiments of the present invention refer to the orientation based on the vehicle itself. The vehicle head represents the front, and the vehicle tail represents the back.

[0042] Optionally, the three-way catalytic converter 102 is a device for purifying the exhaust discharged from the engine exhaust manifold. The three-way catalytic converter 102 can convert harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in the exhaust discharged from the engine exhaust manifold into harmless carbon dioxide, water, and nitrogen through oxidation and reduction, so as to purify the exhaust discharged from the engine exhaust manifold. The three-way catalytic converter 102 can be composed of a shock-absorbing layer, a carrier, and a catalyst.

[0043] Optionally, the particulate trap 103 is a device for trapping particulate matter in the exhaust discharged from the engine exhaust manifold. The particulate trap 103 can trap particulate matter in the exhaust discharged from the engine exhaust manifold, perform a certain purification treatment on the exhaust discharged from the engine exhaust manifold, and avoid environmental pollution by the exhaust. The particulate trap 103 can be a gasoline particulate filter (GPF).

[0044] Optionally, the front-back moving mechanism 104 is a device for driving the particulate trap 103 to move to a set position in the front-back direction of the vehicle. The front-back moving mechanism 104 is arranged in the front-back direction of the vehicle. The particulate trap 103 is drivingly connected to the front-back moving mechanism 104 and can be driven by the front-back moving mechanism 104 to move to a set position in the front-back direction of the vehicle.

[0045] Optionally, a plurality of set positions corresponding to the particulate trap 103 are preset. Each set position is a position that the front-back moving mechanism 104 can drive the particulate trap 103 to move to in the front-back direction of the vehicle. All set positions are arranged behind the three-way catalytic converter 102. The distances between different set positions and the three-way catalytic converter 102 are different. The front-back moving mechanism 104 can drive the particulate trap 103 to move to each set position in the front-back direction of the vehicle.

[0046] Optionally, the set positions are sorted in ascending order of the distance from the three-way catalytic converter 102. The set position ranked first has the smallest distance from the three-way catalytic converter 102, and is the closest to the three-way catalytic converter 102 and the engine exhaust manifold. The set position ranked first is set as the head set position corresponding to the particulate trap 103. The head set position corresponding to the particulate trap 103 is the set position closest to the three-way catalytic converter 102 and the engine exhaust manifold. The set position ranked last has the largest distance from the three-way catalytic converter 102, and is the farthest from the three-way catalytic converter 102 and the engine exhaust manifold. The set position ranked last is set as the tail set position corresponding to the particulate trap 103. The tail set position corresponding to the particulate trap 103 is the set position farthest from the three-way catalytic converter 102 and the engine exhaust manifold.

[0047] Optionally, in the initial state, the particulate trap 103 is at the head set position corresponding to the particulate trap 103.

[0048] Optionally, the control module 105 is a device for controlling the front and rear moving mechanism 104 to drive the particulate trap 103 to move in the front and rear direction of the vehicle to a specified set position according to the pressure information and temperature information corresponding to the engine exhaust manifold and the particulate trap 103, so as to adjust the position of the particulate trap 103 during the process of treating the vehicle exhaust gas through the three-way catalytic converter 102 and the particulate trap 103, and ensure the working performance of the engine and the particulate trap 103. The control module 105 can be an electronic control unit (ECU) of the vehicle.

[0049] Optionally, the control module 105 periodically obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap 103, including: the control module 105 periodically obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap 103 at a preset time interval.

[0050] Optionally, the control module 105 obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap 103 every preset time interval. The preset time interval can be set according to service requirements. Exemplarily, the preset time interval is 1 minute, and the control module 105 obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap 103 every 1 minute.

[0051] Optionally, the current pressure information includes the current exhaust back pressure of the engine and / or the current differential pressure of the particulate trap 103. The current exhaust back pressure of the engine is the exhaust back pressure newly collected by an exhaust back pressure sensor provided on the engine. The current differential pressure of the particulate trap 103 is the differential pressure newly collected by a differential pressure sensor provided on the particulate trap 103.

[0052] Optionally, the control module 105 has respectively established communication connections with the exhaust back pressure sensor provided on the engine and the differential pressure sensor provided on the particulate trap 103, and can obtain the exhaust back pressure collected by the exhaust back pressure sensor and the differential pressure collected by the differential pressure sensor based on the established communication connections.

[0053] Optionally, the current temperature information includes the current temperature of the engine, the current temperature of the particulate trap 103, the current temperature of the first end set position corresponding to the particulate trap 103, and / or the current temperature of the second end set position corresponding to the particulate trap 103. The current temperature of the engine is the temperature newly collected by a temperature sensor provided on the engine. The current temperature of the particulate trap 103 is the temperature newly collected by a temperature sensor provided on the particulate trap 103. The current temperature of the first end set position corresponding to the particulate trap 103 is the temperature newly collected by a temperature sensor provided on the first end set position corresponding to the particulate trap 103. The current temperature of the second end set position corresponding to the particulate trap 103 is the temperature newly collected by a temperature sensor provided on the second end set position corresponding to the particulate trap 103.

[0054] Optionally, the control module 105 has respectively established communication connections with the temperature sensor provided on the engine, the temperature sensor provided on the particulate trap 103, the temperature sensor provided on the first end set position corresponding to the particulate trap 103, and the temperature sensor provided on the second end set position corresponding to the particulate trap 103, and can obtain the temperatures collected by the above temperature sensors based on the established communication connections.

[0055] Optionally, after each acquisition of the current pressure information and the current temperature information corresponding to the engine exhaust manifold and the particulate trap 103, the control module 105 determines the target set position corresponding to the particulate trap 103 according to the current pressure information and the current temperature information. The target set position corresponding to the particulate trap 103 is the set position that the particulate trap 103 needs to be in at the current moment to ensure that the engine and the particulate trap 103 can maintain good working performance.

[0056] Optionally, the control module 105 determines a target setting position corresponding to the particulate trap 103 according to the current pressure information and the current temperature information, including: the control module 105 determines whether the engine is running; if the engine is running, the control module 105 determines whether the current exhaust back pressure of the engine is greater than a preset exhaust back pressure threshold; if the current exhaust back pressure of the engine is greater than the preset exhaust back pressure threshold, the control module 105 determines a target setting position corresponding to the particulate trap 103 according to a rear-end setting position corresponding to the particulate trap 103.

[0057] Optionally, the control module 105 determines whether the engine is running, including: the control module 105 obtains the working state of the vehicle's engine; if the working state of the vehicle's engine is a running state, the control module 105 determines that the engine is running; if the working state of the vehicle's engine is a non-running state, the control module 105 determines that the engine is not running.

[0058] Optionally, the working state of the engine is information set in the engine for indicating whether the engine is running. The working state of the engine is a running state or a non-running state. The working state of the engine being a running state indicates that the engine is running; the working state of the engine being a non-running state indicates that the engine is not running. The control module 105 has established a communication connection with the engine and can obtain the working state of the engine based on the established communication connection.

[0059] Optionally, if the engine is not running, indicating that the engine, the three-way catalyst 102, and the particulate trap 103 are not in a working state, and the control module 105 does not need to adjust the position of the particulate trap 103, then the control module 105 does not perform subsequent operations and waits for the next acquisition of the current pressure information and the current temperature information corresponding to the engine exhaust manifold and the particulate trap 103.

[0060] Optionally, if the current exhaust back pressure of the engine is greater than the preset exhaust back pressure threshold, indicating that the setting position where the particulate trap 103 is located at the current moment is relatively close to the engine exhaust manifold, resulting in a relatively large exhaust back pressure of the engine, and the particulate trap 103 needs to move to a setting position farther from the engine exhaust manifold, then the control module 105 determines a target setting position corresponding to the particulate trap 103 according to a rear-end setting position corresponding to the particulate trap 103.

[0061] Optionally, the rear-end set position corresponding to the particulate filter 103 is at least one of the set positions that is behind the set position where the particulate filter 103 is located at the current moment among all the set positions. The control module 105 determines the target set position corresponding to the particulate filter 103 according to the rear-end set position corresponding to the particulate filter 103, including: obtaining a set position from among the set positions that are behind the set position where the particulate filter 103 is located at the current moment as the target set position corresponding to the particulate filter 103. Thus, when the set position where the particulate filter 103 is located at the current moment is relatively close to the engine exhaust manifold, resulting in a relatively high exhaust back pressure of the engine and the particulate filter 103 needing to move to a set position farther from the engine exhaust manifold, a set position farther from the engine exhaust manifold is determined as the set position that the particulate filter 103 needs to be in at the current moment, so as to ensure that the engine and the particulate filter 103 can maintain good working performance.

[0062] Optionally, after the control module 105 determines whether the current exhaust back pressure of the engine is greater than a preset exhaust back pressure threshold, it further includes: if the current exhaust back pressure of the engine is less than or equal to the preset exhaust back pressure threshold, the control module 105 determines whether the current temperature of the particulate filter 103 is less than a preset temperature threshold; if the current temperature of the particulate filter 103 is less than the preset temperature threshold, the control module 105 determines the tail-end set position corresponding to the particulate filter 103 as the target set position corresponding to the particulate filter 103.

[0063] Optionally, if the current temperature of the particulate filter 103 is less than the preset temperature threshold, indicating that the particulate filter 103 needs to move to the set position farthest from the engine exhaust manifold, the control module 105 determines the tail-end set position corresponding to the particulate filter 103 as the target set position corresponding to the particulate filter 103.

[0064] Optionally, after determining whether the current temperature of the particulate filter 103 is less than the preset temperature threshold, it further includes: if the current temperature of the particulate filter 103 is greater than or equal to the preset temperature threshold and the regeneration mode of the particulate filter 103 is active regeneration, the head-end set position corresponding to the particulate filter 103 is determined as the target set position corresponding to the particulate filter 103.

[0065] Optionally, the regeneration method of the particulate trap 103 is the method by which the particulate trap 103 processes the particulate matter in the particulate trap 103. The regeneration method of the particulate trap 103 is active regeneration or passive regeneration. Active regeneration means that the engine controller actively adjusts the engine parameters to make the temperature and oxygen content in the particulate trap 103 reach the conditions required for active regeneration, and burns the particulate matter in the particulate trap 103. Passive regeneration means that when the temperature and oxygen content in the particulate trap 103 reach the conditions required for active regeneration, the particulate matter in the particulate trap 103 is burned without actively adjusting the engine parameters.

[0066] Optionally, if the current temperature of the particulate trap 103 is greater than or equal to the preset temperature threshold, and the regeneration method of the particulate trap 103 is active regeneration, indicating that the particulate trap 103 needs to move to the setting position closest to the engine exhaust manifold, the control module 105 determines the first-end setting position corresponding to the particulate trap 103 as the target setting position corresponding to the particulate trap 103.

[0067] Optionally, after determining whether the current temperature of the particulate trap 103 is less than the preset temperature threshold, it further includes: if the current temperature of the particulate trap 103 is greater than or equal to the preset temperature threshold, and the regeneration method of the particulate trap 103 is passive regeneration, then obtain a setting position from the setting positions in front of the setting position where the particulate trap 103 is located at the current moment as the target setting position corresponding to the particulate trap 103. If the current temperature of the particulate trap 103 is greater than or equal to the preset temperature threshold, and the regeneration method of the particulate trap 103 is passive regeneration, it indicates that the particulate trap 103 needs to move to a setting position closer to the engine exhaust manifold.

[0068] Optionally, after the control module 105 determines the target setting position corresponding to the particulate trap 103, it sends the identification information of the target setting position to the front-back moving mechanism 104, so that after the front-back moving mechanism 104 receives the identification information of the target setting position, it drives the particulate trap 103 to move to the target setting position along the front-back direction of the vehicle. Thus, in the process of treating vehicle exhaust gas through the three-way catalytic converter 102 and the particulate trap 103, the setting position where the particulate trap 103 needs to be at the current moment is determined according to the pressure information and temperature information corresponding to the engine exhaust manifold and the particulate trap 103, and then the setting position where the particulate trap 103 is located is adjusted to the setting position where the particulate trap 103 needs to be at the current moment, ensuring that the engine and the particulate trap 103 can maintain good working performance.

[0069] Optionally, the identification information of the set position is information used to uniquely identify the set position. The identification information of the set position may be a digital number. The identification information of different set positions is different. After receiving the identification information of any set position, the front-back moving mechanism 104 drives the particulate trap 103 to move in the front-back direction of the vehicle to this set position.

[0070] Optionally, after receiving the identification information of the target set position, the front-back moving mechanism 104 drives the particulate trap 103 to move in the front-back direction of the vehicle to the target set position, including: after receiving the identification information of the target set position, the front-back moving mechanism 104 determines whether the set position where the particulate trap 103 is located at the current moment is the same as the target set position according to the identification information of the target set position; if the set position where the particulate trap 103 is located at the current moment is not the same as the target set position, the front-back moving mechanism 104 drives the particulate trap 103 to move in the front-back direction of the vehicle to the target set position; if the set position where the particulate trap 103 is located at the current moment is the same as the target set position, the front-back moving mechanism 104 determines that the particulate trap 103 has been in the target set position and does not perform subsequent operations.

[0071] Optionally, the front-back moving mechanism 104 determines whether the set position where the particulate trap 103 is located at the current moment is the same as the target set position according to the identification information of the target set position, including: the front-back moving mechanism 104 determines whether the identification information of the set position where the particulate trap 103 is located at the current moment is the same as that according to the identification information of the target set position; if the identification information of the set position where the particulate trap 103 is located at the current moment is the same as that according to the identification information of the target set position, it is determined that the set position where the particulate trap 103 is located at the current moment is the same as the target set position; if the identification information of the set position where the particulate trap 103 is located at the current moment is not the same as that according to the identification information of the target set position, it is determined that the set position where the particulate trap 103 is located at the current moment is not the same as the target set position.

[0072] In the technical solution of the embodiment of the present invention, during the process of treating vehicle exhaust gas by the three-way catalytic converter and the particulate trap, the control module periodically obtains the current pressure information and the current temperature information corresponding to the engine exhaust manifold and the particulate trap. According to the current pressure information and the current temperature information, the target set position corresponding to the particulate trap is determined, and then the identification information of the target set position is sent to the front-back moving mechanism, so that after receiving the identification information of the target set position, the front-back moving mechanism drives the particulate trap to move to the target set position along the front-back direction of the vehicle, solving the problem that in the vehicle exhaust gas treatment solution of the related technology, the three-way catalytic converter and the particulate trap are arranged on the vehicle only in a fixed arrangement manner, so that the particulate trap is always relatively close to or far from the engine exhaust manifold for a long time, affecting the working performance of the engine or the particulate trap. The beneficial effect is achieved that during the process of treating vehicle exhaust gas by the three-way catalytic converter and the particulate trap, the set position that the particulate trap needs to be in at the current moment can be continuously determined according to the pressure information and the temperature information corresponding to the engine exhaust manifold and the particulate trap, and the particulate trap can be driven to move to the set position that the particulate trap needs to be in at the current moment along the front-back direction of the vehicle, so that the particulate trap can be continuously adjusted to the set position that the particulate trap needs to be in at the current moment, ensuring that the engine and the particulate trap can maintain good working performance.

The embodiment of the present invention is applicable to the situation of adjusting the position of the particulate trap according to the pressure information and the temperature information corresponding to the engine exhaust manifold and the particulate trap during the process of treating vehicle exhaust gas by the three-way catalytic converter and the particulate trap, and ensuring the working performance of the engine and the particulate trap. This method can be applied to the control module in the vehicle exhaust gas treatment system provided in the above embodiments of the present invention. As Figure 2 shown, the method of this embodiment specifically includes:

[0077] Step 201: Regularly obtain the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap.

[0078] Optionally, the regularly obtaining the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap includes: regularly obtaining the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap at a preset time interval; wherein, the current pressure information includes the current exhaust back pressure of the engine and / or the current differential pressure of the particulate trap; the current temperature information includes the current temperature of the engine, the current temperature of the particulate trap, the current temperature at the set position at the head end corresponding to the particulate trap, and / or the current temperature at the set position at the tail end corresponding to the particulate trap.

[0079] Optionally, the control module obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap every preset time interval. The preset time interval can be set according to service requirements. Exemplarily, the preset time interval is 1 minute, and the control module obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap every 1 minute.

[0080] Optionally, the current exhaust back pressure of the engine is the exhaust back pressure newly collected by the exhaust back pressure sensor provided on the engine. The current differential pressure of the particulate trap is the differential pressure newly collected by the differential pressure sensor provided on the particulate trap. The control module has established communication connections with the exhaust back pressure sensor provided on the engine and the differential pressure sensor provided on the particulate trap respectively, and can obtain the exhaust back pressure collected by the exhaust back pressure sensor and the differential pressure collected by the differential pressure sensor based on the established communication connections.

[0081] Optionally, the current temperature of the engine is the temperature newly collected by the temperature sensor provided on the engine. The current temperature of the particulate trap is the temperature newly collected by the temperature sensor provided on the particulate trap. The current temperature at the set position at the head end corresponding to the particulate trap is the temperature newly collected by the temperature sensor provided at the set position at the head end corresponding to the particulate trap. The current temperature at the set position at the tail end corresponding to the particulate trap is the temperature newly collected by the temperature sensor provided at the set position at the tail end corresponding to the particulate trap.

[0082] Optionally, the control module has established communication connections with the temperature sensor provided on the engine, the temperature sensor provided on the particulate trap, the temperature sensor provided at the set position at the head end corresponding to the particulate trap, and the temperature sensor provided at the set position at the tail end corresponding to the particulate trap respectively, and can obtain the temperatures collected by the above temperature sensors based on the established communication connections.

[0083] Step 202: Determine a target setting position corresponding to the particulate trap according to the current pressure information and the current temperature information.

[0084] Optionally, the determining a target setting position corresponding to the particulate trap according to the current pressure information and the current temperature information includes: determining whether the engine is running; if the engine is running, determining whether a current exhaust back pressure of the engine is greater than a preset exhaust back pressure threshold; and if the current exhaust back pressure of the engine is greater than the preset exhaust back pressure threshold, determining a target setting position corresponding to the particulate trap according to a rear-end setting position corresponding to the particulate trap.

[0085] Optionally, the determining whether the engine is running includes: obtaining an operating state of an engine of a vehicle; if the operating state of the engine of the vehicle is an operating state, determining that the engine is running; and if the operating state of the engine of the vehicle is a non-operating state, determining that the engine is not running.

[0086] Optionally, the operating state of the engine is information set in the engine for indicating whether the engine is running. The operating state of the engine is an operating state or a non-operating state. The operating state of the engine being an operating state indicates that the engine is running; and the operating state of the engine being a non-operating state indicates that the engine is not running. The control module has established a communication connection with the engine and can obtain the operating state of the engine based on the established communication connection.

[0087] Optionally, if the engine is not running, it indicates that the engine, the three-way catalyst, and the particulate trap are not in an operating state. The control module does not need to adjust the position of the particulate trap, so the control module does not perform subsequent operations and waits for the next acquisition of the current pressure information and the current temperature information corresponding to the engine exhaust manifold and the particulate trap.

[0088] Optionally, if the current exhaust back pressure of the engine is greater than the preset exhaust back pressure threshold, it indicates that the setting position where the particulate trap is located at the current moment is relatively close to the engine exhaust manifold, resulting in a relatively large exhaust back pressure of the engine. The particulate trap needs to move to a setting position farther from the engine exhaust manifold. Then, the control module determines a target setting position corresponding to the particulate trap according to a rear-end setting position corresponding to the particulate trap.

[0089] Optionally, the backend set position corresponding to the particulate filter is at least one of the set positions that is behind the set position where the particulate filter is located at the current moment among all the set positions. The control module determines the target set position corresponding to the particulate filter according to the backend set position corresponding to the particulate filter, including: obtaining a set position from among the set positions that are behind the set position where the particulate filter is located at the current moment as the target set position corresponding to the particulate filter.

[0090] Thus, when the set position where the particulate filter is located at the current moment is relatively close to the engine exhaust manifold, resulting in a relatively high exhaust back pressure of the engine and the particulate filter needing to move to a set position farther from the engine exhaust manifold, a set position farther from the engine exhaust manifold is determined as the set position where the particulate filter needs to be at the current moment to ensure that the engine and the particulate filter can maintain good working performance.

[0091] Optionally, after determining whether the current exhaust back pressure of the engine is greater than a preset exhaust back pressure threshold, it further includes: if the current exhaust back pressure of the engine is less than or equal to the preset exhaust back pressure threshold, determining whether the current temperature of the particulate filter is less than a preset temperature threshold; if the current temperature of the particulate filter is less than the preset temperature threshold, determining the tail-end set position corresponding to the particulate filter as the target set position corresponding to the particulate filter.

[0092] Optionally, if the current temperature of the particulate filter is less than the preset temperature threshold, indicating that the particulate filter needs to move to the set position farthest from the engine exhaust manifold, the control module determines the tail-end set position corresponding to the particulate filter as the target set position corresponding to the particulate filter.

[0093] Optionally, after determining whether the current temperature of the particulate filter is less than the preset temperature threshold, it further includes: if the current temperature of the particulate filter is greater than or equal to the preset temperature threshold and the regeneration mode of the particulate filter is active regeneration, determining the head-end set position corresponding to the particulate filter as the target set position corresponding to the particulate filter.

[0094] Optionally, the regeneration method of the particulate filter is the method by which the particulate filter processes the particulate matter in the particulate filter. The regeneration method of the particulate filter is active regeneration or passive regeneration. Active regeneration means that the engine controller actively adjusts the engine parameters to make the temperature and oxygen content in the particulate filter reach the conditions required for active regeneration, and burns the particulate matter in the particulate filter. Passive regeneration means that when the temperature and oxygen content in the particulate filter reach the conditions required for active regeneration, the particulate matter in the particulate filter is burned without actively adjusting the engine parameters.

[0095] Optionally, if the current temperature of the particulate filter is greater than or equal to the preset temperature threshold and the regeneration method of the particulate filter is active regeneration, indicating that the particulate filter needs to move to the setting position closest to the engine exhaust manifold, the control module determines the first-end setting position corresponding to the particulate filter as the target setting position corresponding to the particulate filter.

[0096] Optionally, after determining whether the current temperature of the particulate filter is less than the preset temperature threshold, it further includes: if the current temperature of the particulate filter is greater than or equal to the preset temperature threshold and the regeneration method of the particulate filter is passive regeneration, obtain a setting position from among the setting positions in front of the setting position where the particulate filter is located at the current moment as the target setting position corresponding to the particulate filter. If the current temperature of the particulate filter is greater than or equal to the preset temperature threshold and the regeneration method of the particulate filter is passive regeneration, it indicates that the particulate filter needs to move to a setting position closer to the engine exhaust manifold.

[0097] Step 203: Send the identification information of the target setting position to the front-back moving mechanism, so that after receiving the identification information of the target setting position, the front-back moving mechanism drives the particulate filter to move in the front-back direction of the vehicle to the target setting position.

[0098] Optionally, after the control module determines the target setting position corresponding to the particulate filter, it sends the identification information of the target setting position to the front-back moving mechanism, so that after receiving the identification information of the target setting position, the front-back moving mechanism drives the particulate filter to move in the front-back direction of the vehicle to the target setting position.

[0099] Thus, in the process of treating vehicle exhaust gas through a three-way catalytic converter and a particulate trap, the set position that the particulate trap needs to be in at the current moment is determined according to the pressure information and temperature information corresponding to the engine exhaust manifold and the particulate trap, and then the set position where the particulate trap is located is adjusted to the set position that the particulate trap needs to be in at the current moment, ensuring that the engine and the particulate trap can maintain good working performance.

[0100] Optionally, the identification information of the set position is the information used to uniquely identify the set position. The identification information of the set position can be a digital number. The identification information of different set positions is different. After receiving the identification information of any set position, the front-back moving mechanism drives the particulate trap to move in the front-back direction of the vehicle to this set position.

[0101] Optionally, after receiving the identification information of the target set position, the front-back moving mechanism driving the particulate trap to move in the front-back direction of the vehicle to the target set position includes: after receiving the identification information of the target set position, the front-back moving mechanism determines whether the set position where the particulate trap is located at the current moment is the same as the target set position according to the identification information of the target set position; if the set position where the particulate trap is located at the current moment is not the same as the target set position, the front-back moving mechanism drives the particulate trap to move in the front-back direction of the vehicle to the target set position; if the set position where the particulate trap is located at the current moment is the same as the target set position, the front-back moving mechanism determines that the particulate trap is already in the target set position and does not perform subsequent operations.

[0102] Optionally, the front-back moving mechanism determining whether the set position where the particulate trap is located at the current moment is the same as the target set position according to the identification information of the target set position includes: the front-back moving mechanism determines whether the identification information of the set position where the particulate trap is located at the current moment is the same as that according to the identification information of the target set position; if the identification information of the set position where the particulate trap is located at the current moment is the same as that according to the identification information of the target set position, it is determined that the set position where the particulate trap is located at the current moment is the same as the target set position; if the identification information of the set position where the particulate trap is located at the current moment is not the same as that according to the identification information of the target set position, it is determined that the set position where the particulate trap is located at the current moment is not the same as the target set position.

[0103] The technical solution of the embodiment of the present invention obtains the current pressure information and current temperature information corresponding to the engine exhaust manifold and the particulate trap at regular intervals; then determines the target set position corresponding to the particulate trap according to the current pressure information and the current temperature information; and sends the identification information of the target set position to the front-back moving mechanism, so that after receiving the identification information of the target set position, the front-back moving mechanism drives the particulate trap to move to the target set position along the front-back direction of the vehicle, solving the problem that the vehicle exhaust gas treatment solution in the related art only arranges the three-way catalytic converter and the particulate trap on the vehicle in a fixed arrangement manner, resulting in the particulate trap being relatively close to or far from the engine exhaust manifold for a long time, affecting the working performance of the engine or the particulate trap. The beneficial effect is achieved that during the process of treating vehicle exhaust gas by the three-way catalytic converter and the particulate trap, the set position where the particulate trap needs to be at the current moment can be continuously determined according to the pressure information and temperature information corresponding to the engine exhaust manifold and the particulate trap, and the particulate trap can be driven to move to the set position where the particulate trap needs to be at the current moment along the front-back direction of the vehicle, so as to continuously adjust the particulate trap to the set position where the particulate trap needs to be at the current moment, ensuring that the engine and the particulate trap can maintain good working performance.

The beneficial effect is achieved that during the process of treating the vehicle exhaust gas by the three-way catalytic converter and the particulate trap, the set position that the particulate trap needs to be in at the current moment can be continuously determined according to the pressure information and the temperature information corresponding to the engine exhaust manifold and the particulate trap, and the particulate trap can be driven to move in the front-back direction of the vehicle to the set position that the particulate trap needs to be in at the current moment, so as to continuously adjust the particulate trap to the set position that the particulate trap needs to be in at the current moment, ensuring that the engine and the particulate trap can maintain good working performance.
