Description

Technical Field

[0001] This disclosure relates to the field of engine aftertreatment, and more particularly to a method for detecting a particulate filter, electronic equipment, and vehicle. Background Technology

[0002] With the rapid development of vehicle technology, vehicles have become an important means of transportation in people's daily lives. During vehicle operation, particulate filters are mainly used to reduce particulate matter in vehicle exhaust pollution. A particulate matter sensor is installed after the particulate filter to monitor its particulate matter collection performance.

[0003] The performance of particulate traps is usually tested when carbon accumulation in the particulate sensor reaches a certain level, triggering regeneration. This results in a long testing time and low testing efficiency. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to propose a detection method, electronic equipment and vehicle for particulate traps, in order to solve the current problems of long detection time and low detection efficiency of particulate traps.

[0005] To achieve the above objectives, a first aspect of this disclosure provides a method for detecting particulate matter in a particulate filter, wherein a particulate sensor connected to the particulate filter for detecting particulate matter emitted from the rear end of the particulate filter is provided in a vehicle, the method comprising:

[0006] The engine obtains the initial carbon load level value corresponding to a preset time in the current driving cycle, and the first average carbon load level value corresponding to a preset driving cycle segment, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle.

[0007] If the particulate sensor is determined to be in a non-regenerative state, and in response to the condition that the average carbon load level is greater than a preset carbon load level threshold and the initial carbon load level is greater than the preset carbon load level threshold, the detection result of the particulate trap is determined to be normal operation, wherein the particulate trap is connected to the engine.

[0008] Based on the same inventive concept, a second aspect of this disclosure provides a detection device for a particle trap, comprising:

[0009] The data acquisition module is configured to acquire the initial carbon load level value of the engine within a preset time period in the current driving cycle, and the first average carbon load level value corresponding to a preset driving cycle segment, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle.

[0010] The detection module is configured to determine that the particulate sensor is in a non-regenerative state, and in response to the condition that the average carbon load level value is greater than a preset carbon load level threshold and the initial carbon load level value is greater than the preset carbon load level threshold, determine that the detection result of the particulate trap is normal operation, wherein the particulate trap is connected to the engine.

[0011] Based on the same inventive concept, a third aspect of this disclosure proposes an electronic device, including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor, when executing the computer program, implements the detection method of the particle trap as described above.

[0012] Based on the same inventive concept, a fourth aspect of this disclosure provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to execute the detection method of the particle trap as described above.

[0013] Based on the same inventive concept, the fifth aspect of this disclosure provides a vehicle including a detection device for a particulate trap as described in the second aspect, an electronic device as described in the third aspect, or a storage medium as described in the fourth aspect.

[0014] As can be seen from the above, this disclosure proposes a detection method, electronic equipment, and vehicle for a particulate filter. The vehicle is equipped with a particulate filter connected to the engine to collect and reduce particulate matter in exhaust emissions from the vehicle engine. A particulate sensor connected to the particulate filter is also provided to detect particulate matter emitted from the rear end of the particulate filter. The method involves acquiring the initial carbon load level of the engine within a preset time period in the current driving cycle, and the first average carbon load level corresponding to a preset driving cycle segment, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle. When the particulate sensor is determined to be in a non-regenerative state, the average carbon load level and the initial carbon load level are compared with preset carbon load level thresholds. When both the average carbon load level and the initial carbon load level are greater than the preset carbon load level threshold, the detection result for the particulate filter is determined to be normal operation, indicating that the particulate filter is performing well. This solution allows for performance testing of the particulate filter before the particulate sensor undergoes regeneration. This eliminates the need to wait for carbon buildup to trigger regeneration before testing, thus shortening testing time and improving detection efficiency. Simultaneously, it reduces the number of particulate sensor regeneration cycles, extending the sensor's lifespan. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] The following are definitions of terms used in this disclosure:

[0023] OBD: On-Board Diagnostics (OBD) system monitors the engine's operation at all times to see if the car's exhaust emissions exceed the standard. If they do, it will immediately issue a warning.

[0024] PM sensor: Particulate matter sensor.

[0025] DPF: Diesel Particulate Filter (DPF) is a ceramic filter installed in the emission system of a diesel engine that captures particulate matter before it enters the atmosphere.

[0026] PM: Particulate matter.

[0027] PN: Particle number.

[0028] With the upgrading of emission regulations for light-duty vehicles, the emission limits for gaseous pollutants and solid particulate matter have been gradually tightened. To meet the requirements of emission regulations on particulate matter, particulate filters are added to exhaust aftertreatment systems to treat particulate matter (PM) and particulate number (PN) in vehicle exhaust. Simultaneously, a particulate sensor is added after the particulate filter to monitor its particulate collection performance; the particulate filter's particulate collection efficiency (filtration efficiency) characterizes its performance.

[0029] The particulate filter's efficiency can be calculated using the cumulative carbon cycles or carbon loading levels of the upstream and downstream particulate sensors. However, using two particulate sensors is costly. To save on overall vehicle costs, carbon particulate emissions upstream of the particulate filter are calculated using a carbon model. Therefore, only one particulate sensor is installed downstream of the particulate filter, and the carbon particulate emissions upstream of the particulate filter are replaced by a carbon model from the engine outlet. When the carbon loading level of the downstream particulate sensor reaches 100% spontaneous regeneration, the carbon loading level of the virtual particulate sensor directly reflects the particulate filter's efficiency.

[0030] Currently, a virtual particulate matter sensor (i.e., an engine soot emission model) upstream of the particulate filter is used to measure soot. If the carbon load level of the virtual particulate matter sensor is less than the fault diagnosis threshold, the particulate filter can be considered to have a fault of low collection efficiency. That is, the performance of the particulate filter is usually tested only when the carbon accumulation in the particulate matter sensor reaches a certain level and triggers regeneration, resulting in long detection time and low detection efficiency.

[0031] Based on the above description, this embodiment proposes a detection method for a particulate matter trap. The vehicle is equipped with a particulate matter sensor connected to the particulate matter trap for detecting particulate matter emitted from its downstream end. Figure 1 As shown, the method includes:

[0032] Step 101: Obtain the initial carbon load level value of the engine within a preset time period in the current driving cycle, and the first average carbon load level value corresponding to the preset driving cycle segment, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle.

[0033] In practice, a particulate filter is installed inside the vehicle. The particulate filter is installed in the ceramic filter of the diesel engine emission system and is connected to the engine. It can capture particulate matter before it enters the atmosphere, and is mainly used to reduce particulate matter and particle number in vehicle exhaust pollution.

[0034] Carbon particulate emissions upstream of the particulate trap are calculated and determined using a carbon model, which serves as a virtual particulate sensor. A particulate sensor is installed downstream of the particulate trap.

[0035] When the engine starts running, as the exhaust temperature rises, the particulate matter sensor releases its dew point, initializes and regenerates, and then enters the measurement state after regeneration.

[0036] The initial carbon load level of the engine within a preset time period in the current driving cycle is obtained. This initial carbon load level represents the carbon load level emitted by the engine within the preset time period of the current driving cycle, and its magnitude is equal to the sum of the carbon load level captured by the particulate filter and the carbon load level not captured by the particulate filter (leaked). A driving cycle includes engine start, vehicle operation, engine shutdown, and power-on.

[0037] The preset time is determined by the model of the particulate matter sensor, and the preset time is the trigger regeneration time corresponding to the particulate matter sensor. For example, the preset time is 150 seconds.

[0038] A first average carbon load level corresponding to a preset driving cycle segment is obtained, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle. It is understood that carbon particles in the upstream virtual particulate matter sensor and the downstream particulate matter sensor accumulate over time; therefore, the initial carbon load level gradually increases over the preset time period, and the first average carbon load level also gradually increases over time until the particulate matter sensor triggers regeneration.

[0039] For example, a driving cycle segment includes the current driving cycle and the two driving cycles preceding the current driving cycle, that is, a total of three driving cycles.

[0040] Specifically, the process of determining the first average carbon loading level includes:

[0041] The number of driving cycles contained in the driving cycle segment and the first carbon load level value corresponding to each driving cycle are obtained, wherein the first carbon load level value is the carbon load level value corresponding to the entire driving cycle. The first carbon load level values ​​corresponding to all driving cycles are summed, and the sum is compared with the number of driving cycles to obtain the first average carbon load level value corresponding to the driving cycle segment.

[0042] For example, the number of driving cycles included in the driving cycle segment is three, namely driving cycle A, driving cycle B and driving cycle C. The first carbon load level value corresponding to driving cycle A is 900%, the first carbon load level value corresponding to driving cycle B is 600%, and the first carbon load level value corresponding to driving cycle C is 750%. Therefore, the first average carbon load level value corresponding to the driving cycle segment is 750%.

[0043] Step 102: Determine that the particulate sensor is in a non-regenerative state. In response to the condition that the first average carbon load level value is greater than a preset carbon load level threshold and the initial carbon load level value is greater than the preset carbon load level threshold, determine that the detection result of the particulate trap is normal operation, wherein the particulate trap is connected to the engine.

[0044] In practice, the particulate filter is a periodic regeneration device. As particulate matter accumulates in the particulate filter, the carbon particles in the filter undergo periodic regeneration after reaching a certain concentration. This regeneration involves increasing the exhaust temperature, causing the particulate matter in the filter to combine with oxygen in the exhaust, resulting in an oxidation reaction that removes the accumulated particulate matter. During regeneration, the internal temperature of the particulate filter is typically between 550°C and 650°C, and can reach 1100°C under extreme idling conditions.

[0045] When the particulate sensor is in non-regenerating mode, the first average carbon loading level and the initial carbon loading level are compared with preset carbon loading level thresholds. If both the first average carbon loading level and the initial carbon loading level are greater than the preset carbon loading level threshold, it indicates that the particulate trap does not have a problem with decreased trapping performance, and the detection result of the particulate trap is determined to be normal operation.

[0046] In this embodiment, the preset carbon load level threshold is set by the user according to actual needs. For example, the preset carbon load level threshold is 550%.

[0047] The above scheme incorporates a particulate filter in the vehicle, connected to the engine, to collect and reduce particulate matter in exhaust emissions from the vehicle engine. A particulate sensor connected to the particulate filter is also included to detect particulate matter emitted from the rear end of the particulate filter. The system acquires the initial carbon load level of the engine within a preset time period in the current driving cycle, and the first average carbon load level for a preset driving cycle segment, where the preset driving cycle segment includes the current driving cycle and at least one adjacent driving cycle. When the particulate sensor is determined to be in a non-regenerative state, the first average carbon load level and the initial carbon load level are compared with preset carbon load level thresholds. If both the first average carbon load level and the initial carbon load level are greater than the preset carbon load level threshold, the particulate filter is considered to be operating normally, indicating good performance. This solution allows for performance testing of the particulate filter before the particulate sensor undergoes regeneration. This eliminates the need to wait for carbon buildup to trigger regeneration before testing, thus shortening testing time and improving detection efficiency. Simultaneously, it reduces the number of particulate sensor regeneration cycles, extending the sensor's lifespan.

[0048] In some embodiments, after step 102, the method further includes:

[0049] Step 103: Send a sleep command to the particulate matter sensor to control the particulate matter sensor to enter sleep mode.

[0050] In practice, once the particle trap's detection result indicates normal operation, a sleep command is sent to the particulate sensor to control it to enter sleep mode. This sleep command can be a direct instruction from the vehicle's electronic controller to the particulate sensor, or it can be an instruction sent from the vehicle's electronic controller to the particulate sensor's controller, which in turn sends the instruction to the particulate sensor's controller.

[0051] The above scheme controls the particulate matter sensor to enter a dormant state after confirming that the particulate matter collector is operating normally. This prevents the particulate matter sensor from continuing to accumulate carbon, which could trigger regeneration, causing unnecessary wear and tear on the particulate matter sensor and reducing its lifespan.

[0052] In some embodiments, the method further includes:

[0053] Step 10A: In response to the fact that the first average carbon loading level value is not greater than a preset carbon loading level threshold and the initial carbon loading level value is greater than the preset carbon loading level threshold, the first resistance value sent by the particulate matter sensor is received.

[0054] In practice, as the engine runs, the carbon particles leaking from the rear end of the particulate filter will gradually accumulate between the two electrodes of the particulate sensor. Eventually, the carbon particles bridge the two electrodes, causing the resistance of the two electrodes of the particulate sensor to decrease. When the resistance decreases to a certain value, the particulate sensor is regenerated.

[0055] If, during particulate matter sensor regeneration, it is determined that the first average carbon load level is greater than a preset carbon load level threshold, and the initial carbon load level is also greater than the preset carbon load level threshold, it indicates that the particulate trap may be faulty and further judgment is required. At this time, the first resistance value sent by the particulate matter sensor is received.

[0056] The specific situations where the first average carbon loading level value is not greater than the preset carbon loading level threshold, and the initial carbon loading level value is greater than the preset carbon loading threshold, include:

[0057] Case 1: The first average carbon loading level is greater than the preset carbon loading level threshold, and the initial carbon loading level is less than the preset carbon loading level threshold.

[0058] Scenario 2: The first average carbon loading level is greater than the preset carbon loading level threshold, and the initial carbon loading level is equal to the preset carbon loading level threshold.

[0059] Scenario 3: The first average carbon loading level is less than the preset carbon loading level threshold, and the initial carbon loading level is greater than the preset carbon loading level threshold.

[0060] Case 4: The first average carbon loading level is equal to the preset carbon loading level threshold, and the initial carbon loading level is greater than the preset carbon loading level threshold.

[0061] Case 5: The first average carbon loading level is less than the preset carbon loading level threshold, and the initial carbon loading level is also less than the preset carbon loading level threshold.

[0062] Case 6: The first average carbon loading level is less than the preset carbon loading level threshold, and the initial carbon loading level is equal to the preset carbon loading level threshold.

[0063] Case 7: The first average carbon loading level is equal to the preset carbon loading level threshold, and the initial carbon loading level is less than the preset carbon loading level threshold.

[0064] Case 8: The first average carbon loading level is equal to the preset carbon loading level threshold, and the initial carbon loading level is equal to the preset carbon loading level threshold.

[0065] Step 10B: Determine that the first resistance value is less than a preset resistance threshold, send a regeneration command to the particulate matter sensor, and control the particulate matter sensor to regenerate.

[0066] In practice, as the engine runs, the carbon particles leaking from the rear end of the particulate filter will gradually accumulate between the two electrodes of the particulate sensor. Finally, the carbon particles bridge the two electrodes, making the resistance of the two electrodes of the particulate sensor smaller.

[0067] After receiving the first resistance value from the particulate matter sensor, the first resistance value is compared with a preset resistance threshold. When the first resistance value is less than the preset resistance threshold, a regeneration command is sent to the particulate matter sensor, triggering the particulate matter sensor to regenerate.

[0068] Step 10C: Determine the second average carbon load level value of the engine corresponding to the preset driving cycle segment when the particulate sensor is regenerated, and determine the detection result of the particulate trap based on the second average carbon load level value.

[0069] In practice, when the particulate matter sensor is regenerated, the engine obtains the second average carbon load level value corresponding to the preset driving cycle segment, at which time carbon accumulation occurs again due to the particulate matter sensor.

[0070] When the carbon load level of the downstream particulate sensor reaches the regeneration threshold, the second average carbon load level of the virtual particulate sensor directly reflects the efficiency of the particulate filter. The filter's collection efficiency is expressed by the formula:

[0071]

[0072] For example, when the particle sensor downstream of the particle trap spontaneously regenerates, if the second average carbon load level of the virtual particle sensor is 1000%, it means the particle trap's collection efficiency is 90%; if the second average carbon load level of the virtual particle sensor is 550%, it means the particle trap's collection efficiency is 82%. Therefore, there is no need to calculate the actual collection efficiency of the particle trap; it is only necessary to compare the carbon load level value of the virtual particle sensor with the preset carbon load level threshold.

[0073] The performance of the particle trap was tested based on the obtained second average carbon load level value, and the test results were obtained.

[0074] With the above scheme, when the conditions for normal operation of the particulate trap are not met, such that the average carbon load level is greater than the preset carbon load level threshold and the initial carbon load level is greater than the preset carbon load level threshold, the particulate sensor is regenerated based on the resistance value of the particulate sensor, and a second average carbon load level is reacquired when regeneration is triggered, so as to realize the detection of the particulate trap.

[0075] In some embodiments, step 10C specifically includes:

[0076] Step 10C1: Obtain the preset fault threshold.

[0077] Step 10C2: Determine that the second average carbon load level is less than or equal to the fault threshold, and determine that the detection result of the particle trap is faulty.

[0078] In practice, a preset fault threshold is obtained, and the second average carbon load level is compared with the preset fault threshold. When the second average carbon load level is less than or equal to the fault threshold, it indicates that the particle trap has a low collection efficiency and that the particle trap is faulty; that is, the detection result of the particle trap is determined to be faulty.

[0079] In some embodiments, after determining that the particulate filter is faulty, a prompt message is output. This prompt message alerts the user to the faulty particulate filter, allowing the user to inspect and repair both the particulate filter and the engine. Specifically, the prompt message may be displayed in at least one of the following ways: a continuously illuminated malfunction indicator light, a flashing malfunction indicator light, a voice prompt, a text prompt, or an image prompt.

[0080] When the prompt message is displayed as a text or image, its display location includes at least one of the following: HUD display, instrument panel display, central control screen display, window display, and in-vehicle equipment linkage. The HUD display is a head-up display.

[0081] For example, the prompt message is displayed by the fault light remaining on:

[0082] The vehicle is equipped with a fault light to indicate a malfunction. When a fault is detected in the particulate filter, the fault light will be illuminated. The illuminated color is set to the primary color, such as yellow.

[0083] Another example is that the prompt message is displayed by a flashing malfunction indicator light:

[0084] The vehicle is equipped with a fault light to indicate a malfunction. When a fault is detected in the particulate filter, the fault light inside the vehicle will flash, and the light color will be set to yellow.

[0085] In another example, the prompt message is delivered via voice reminder:

[0086] When a malfunction is detected in the particle trap, the voice message "Attention! Particle trap malfunction" is output.

[0087] In another example, the prompt message is presented as a text reminder, and the prompt message is displayed on the central control screen:

[0088] When a malfunction is detected in the particulate filter, the system outputs the text message "Attention! The particulate filter is currently malfunctioning" and displays the message on the central control screen.

[0089] In some embodiments, step 10C specifically includes:

[0090] Step 10CA: Obtain the preset fault threshold.

[0091] Step 10CB: Determine that the second average carbon load level is greater than the fault threshold and less than the preset carbon load level threshold, and send an initialization command to the particulate matter sensor to control the particulate matter sensor to initialize.

[0092] In practice, a preset fault threshold is obtained, and the second average carbon load level is compared with the preset fault threshold. When the second average carbon load level is greater than the fault threshold but less than the preset carbon load level threshold, it means that the current second average carbon load level cannot determine whether the particulate trap is operating normally or has a fault. At this time, an initialization command is sent to the particulate sensor to control the particulate sensor to initialize, so that the first average carbon load level can be re-obtained and the detection result of the particulate trap can be determined based on the new first average carbon load level value.

[0093] Step 10CC: Determine the new initial carbon load level value of the engine within a preset time period in the current driving cycle, and the new first average carbon load level value corresponding to the preset driving cycle segment, until the detection result of the particulate filter is determined to be normal operation or faulty based on the new initial carbon load level value and the new first average carbon load level value.

[0094] In practice, the new initial carbon load level value of the engine within a preset time period in the current driving cycle and the new first average carbon load level value corresponding to the preset driving cycle segment are re-acquired, and the new initial carbon load level value and the new first average carbon load value are compared with the preset carbon load level threshold respectively.

[0095] If both the new initial carbon load level and the new first average carbon load level are greater than the preset carbon load level threshold, the detection result of the particulate trap is determined to be normal operation, and a sleep command is sent to the particulate sensor.

[0096] If both the new initial carbon load level and the new first average carbon load level are greater than the preset carbon load level threshold, then when the particulate sensor is regenerated, the engine's new second average carbon load level corresponding to the preset driving cycle segment is determined, and the detection result of the particulate trap is determined based on the new second average carbon load level.

[0097] Repeat the determination process described in step 10CC above until the detection result of the particulate trap is determined to be either normal operation or malfunction based on the new initial carbon load level value and the new first average carbon load level value.

[0098] In some embodiments, step 101 specifically includes:

[0099] Step 1011: Obtain at least one target operating condition information contained within a preset time period in the current driving cycle.

[0100] Step 1012: For each target operating condition information, the target operating condition information is input into a pre-built engine carbon emission model. After processing by the engine carbon emission model, the target carbon load level value corresponding to the target operating condition information is output. Each target operating condition information corresponds to a target carbon load level value.

[0101] In specific implementation, at least one target operating condition information is acquired within a preset time period in the current driving cycle. This operating condition information refers to the working status of the vehicle during transportation. Based on the vehicle's motion, the operating conditions mainly include: starting, acceleration, constant speed, deceleration, turning, uphill / downhill driving, and parking. Based on the driver's control method, the operating conditions mainly include: gear shifting, coasting (disengaged coasting, neutral coasting, accelerated coasting, stationary coasting), braking (emergency braking, speed-controlled braking, and brake braking), throttle control, steering, and reversing. Based on load conditions, the operating conditions mainly include: unloaded, fully loaded (equal to rated load), and overloaded (exceeding rated load).

[0102] For each target operating condition, the target operating condition information is input into a pre-built engine soot model, which is a soot particulate matter model. The input of the soot model is the operating condition information, and the output is the carbon load level value corresponding to the operating condition information. The target operating condition information is input into the pre-built engine soot model, processed by the engine soot emission model, and the target carbon load level value corresponding to the target operating condition information is output. Each target operating condition corresponds to one target carbon load level value.

[0103] Step 1013: Accumulate the target carbon load level values ​​corresponding to all target operating condition information to obtain the initial carbon load level value corresponding to the preset time in the current driving cycle.

[0104] In practice, after determining the target carbon load level value corresponding to each target operating condition, the target carbon load level values ​​corresponding to all target operating conditions are accumulated, and the accumulated value is the initial carbon load level value corresponding to the preset time in the current driving cycle.

[0105] For example, the target operating condition information includes operating condition information A, operating condition information B, and operating condition information C. The target carbon load level value corresponding to each target operating condition information is determined, that is, the target carbon load level value corresponding to operating condition information A is 200%, the target carbon load level value corresponding to operating condition information B is 300%, and the target carbon load level value corresponding to operating condition information C is 250%. The target carbon load level values ​​corresponding to all target operating condition information are summed to obtain an initial carbon load level value of 750%.

[0106] In some embodiments, prior to step 102, the method further includes:

[0107] Step 10a: Obtain the initial resistance value of the particulate matter sensor.

[0108] In some embodiments, step 102 specifically includes:

[0109] If the initial resistance value is determined to be greater than or equal to a preset resistance threshold, the particulate matter sensor is determined to be in a non-regenerative state.

[0110] In practice, the initial resistance value of the particulate matter sensor is obtained and compared with a preset resistance threshold. When the initial resistance value is greater than or equal to the preset resistance threshold, the particulate matter sensor is in a non-regenerative state.

[0111] In some embodiments, after step 10a, the method further includes:

[0112] Step 10b1: Determine that the initial resistance value is less than the preset resistance threshold, determine that the particulate matter sensor is in regeneration state, and obtain the fault threshold.

[0113] In practice, when the first resistance value is less than a preset resistance threshold, a regeneration command is sent to the particulate matter sensor, triggering the particulate matter sensor to regenerate. At this time, the particulate matter sensor is in regeneration mode and obtains a preset fault threshold, which is then used to compare the first average carbon load level value with the fault threshold to determine whether the particulate matter collector has a fault.

[0114] Step 10b2: Determine that the first average carbon load level value is greater than the fault threshold and less than the preset carbon load level threshold, and send an initialization command to the particulate matter sensor to control the particulate matter sensor to initialize.

[0115] In specific implementation, when the first average carbon load level is greater than the fault threshold but less than the preset carbon load level threshold, it means that the current first average carbon load level cannot determine whether the particulate trap is operating normally or malfunctioning. At this time, an initialization command is sent to the particulate sensor to control it to initialize, so that the average carbon load level can be re-acquired and the detection result of the particulate trap can be determined based on the new average carbon load level.

[0116] Step 10b3: Determine the new initial carbon load level value of the engine within a preset time period in the current driving cycle, and the new first average carbon load level value corresponding to the preset driving cycle segment, until the detection result of the particulate filter is determined to be normal operation or faulty based on the new initial carbon load level value and the new first average carbon load level value.

[0117] In practice, the new initial carbon load level value of the engine within a preset time period in the current driving cycle and the new first average carbon load level value corresponding to the preset driving cycle segment are re-acquired, and the new initial carbon load level value and the new first average carbon load value are compared with the preset carbon load level threshold respectively.

[0118] If both the new initial carbon load level and the new first average carbon load level are greater than the preset carbon load level threshold, the detection result of the particulate trap is determined to be normal operation, and a sleep command is sent to the particulate sensor.

[0119] If both the new initial carbon load level and the new first average carbon load level are not greater than the preset carbon load level threshold, then when the particulate sensor is regenerated, the engine's new first average carbon load level corresponding to the preset driving cycle segment is determined, and the detection result of the particulate trap is determined based on the new first average carbon load level.

[0120] Repeat the determination process described in step 10b3 above until the detection result of the particulate trap is determined to be either normal operation or malfunction based on the new initial carbon load level value and the new first average carbon load level value.

[0121] or,

[0122] Step 10b4: Determine that the first average carbon load level is less than or equal to the fault threshold, and determine that the detection result of the particle trap is faulty.

[0123] In specific implementation, when the first average carbon load level value is less than or equal to the fault threshold, it indicates that the particulate filter has a low collection efficiency and that the particulate filter is faulty. That is, the detection result of the particulate filter is determined to be faulty, and a prompt message is sent. The prompt message is used to remind the user that the particulate filter is faulty so that the user can check and repair the particulate filter and the engine.

[0124] Based on the same inventive concept, another embodiment of this disclosure proposes a detection method for a particle trap, such as... Figure 2 As shown, the method specifically includes:

[0125] Step 201: After initializing the particulate matter sensor and passing the dew point test, regeneration is performed.

[0126] In practice, when the engine is started and running, as the exhaust temperature rises, the particulate matter sensor releases its dew point, undergoes initialization and regeneration, and then enters the measurement state.

[0127] Step 202: Obtain the initial carbon load level value of the engine within a preset time period in the current driving cycle, and the first average carbon load level value corresponding to the preset driving cycle segment.

[0128] In specific implementation, the initial carbon load level value of the engine within a preset time period in the current driving cycle is obtained, wherein the initial carbon load level value represents the carbon load level value emitted by the engine within the preset time period in the current driving cycle. A first average carbon load level value corresponding to a preset driving cycle segment is obtained, wherein the preset driving cycle segment includes the current driving cycle and at least one driving cycle adjacent to the current driving cycle.

[0129] Step 203: Determine whether the particulate matter sensor is in regeneration mode.

[0130] In practice, the initial resistance value of the particulate matter sensor is obtained, and the initial resistance value is compared with a preset resistance threshold to determine whether the particulate matter sensor is in a regeneration state.

[0131] Step 204: Determine that the initial resistance value is greater than or equal to a preset resistance threshold, the particulate matter sensor is in a non-regenerative state, and compare the initial carbon load level value and the first average carbon load level value with the preset carbon load level threshold respectively.

[0132] In practice, the initial resistance value of the particulate matter sensor is obtained and compared with a preset resistance threshold. When the initial resistance value is greater than or equal to the preset resistance threshold, the particulate matter sensor is in a non-regenerative state, and the first average carbon loading level value and the initial carbon loading level value are compared with the preset carbon loading level threshold respectively.

[0133] Step 205: In response to the condition that the first average carbon loading level value is greater than the preset carbon loading level threshold and the initial carbon loading level value is greater than the preset carbon loading level threshold, the detection result of the particle trap is determined to be normal operation.

[0134] In practice, when the first average carbon load level value is greater than the preset carbon load level threshold and the initial carbon load level value is greater than the preset carbon load level threshold, it indicates that the particle trap does not have a problem with decreased trapping performance, and the detection result of the particle trap is determined to be normal operation.

[0135] Step 206: In response to the fact that the first average carbon loading level value is not greater than the preset carbon loading level threshold and the initial carbon loading level value is greater than the preset carbon loading level threshold, the first resistance value sent by the particulate matter sensor is received.

[0136] In practice, if it is determined that the first average carbon load level is greater than the preset carbon load level threshold, and the initial carbon load level is also greater than the preset carbon load level threshold, it indicates that the particle trap may be faulty and further judgment is required. At this time, the first resistance value sent by the particulate sensor is received.

[0137] Step 207: Determine that the first resistance value is less than a preset resistance threshold, control the particulate matter sensor to regenerate, and obtain the second average carbon load level value.

[0138] In practice, as the engine runs, the carbon particles leaking from the rear end of the particulate filter will gradually accumulate between the two electrodes of the particulate sensor. Finally, the carbon particles bridge the two electrodes, making the resistance of the two electrodes of the particulate sensor smaller.

[0139] After receiving the first resistance value from the particulate matter sensor, the first resistance value is compared with a preset resistance threshold. When the first resistance value is less than the preset resistance threshold, a regeneration command is sent to the particulate matter sensor, triggering the particulate matter sensor to regenerate. The second average carbon load level of the engine corresponding to the preset driving cycle segment is obtained during particulate matter sensor regeneration.

[0140] Step 208: Determine that the second average carbon load level is less than or equal to the fault threshold, and determine that the detection result of the particle trap is faulty; determine that the second average carbon load level is greater than the fault threshold and less than the preset carbon load level threshold, and return to step 201.

[0141] In practice, a preset fault threshold is obtained, and the second average carbon load level is compared with the preset fault threshold. When the second average carbon load level is less than or equal to the fault threshold, it indicates that the particle trap has a low collection efficiency and that the particle trap is faulty; that is, the detection result of the particle trap is determined to be faulty.

[0142] When the second average carbon load level is greater than the fault threshold but less than the preset carbon load level threshold, it is impossible to determine whether the particulate trap is operating normally or malfunctioning based on the current second average carbon load level. In this case, return to step 201, send an initialization command to the particulate sensor to initialize it, so that the first average carbon load level can be re-acquired and the detection result of the particulate trap can be determined based on the new first average carbon load level.

[0143] Step 209: Determine that the initial resistance value is less than the preset resistance threshold, determine that the particulate matter sensor is in regeneration state, and obtain the fault threshold.

[0144] In practice, when the first resistance value is less than a preset resistance threshold, a regeneration command is sent to the particulate matter sensor, triggering the particulate matter sensor to regenerate. At this time, the particulate matter sensor is in regeneration mode and obtains a preset fault threshold, which is then used to compare the first average carbon load level value with the fault threshold to determine whether the particulate matter collector has a fault.

[0145] Step 210: Determine that the first average carbon load level is greater than the fault threshold and less than the preset carbon load level threshold, then return to step 201; determine that the first average carbon load level is less than or equal to the fault threshold, and determine that the detection result of the particle trap is faulty.

[0146] In specific implementation, when the first average carbon load level is greater than the fault threshold but less than the preset carbon load level threshold, it is impossible to determine whether the particulate trap is operating normally or malfunctioning based on the current first average carbon load level. At this point, the process returns to step 201, sending an initialization command to the particulate sensor to initialize it, so that the first average carbon load level can be re-acquired and the detection result of the particulate trap can be determined based on the new first average carbon load level.

[0147] When the first average carbon load level is less than or equal to the fault threshold, it indicates that the particulate filter has a low collection efficiency and that the particulate filter is faulty. That is, the detection result of the particulate filter is determined to be faulty, and a prompt message is sent to the user to inform the user that the particulate filter is faulty so that the user can check and repair the particulate filter and the engine.

[0148] It should be noted that the method of this disclosure embodiment can be executed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this disclosure embodiment, and the multiple devices will interact with each other to complete the method described.
