Description

Technical Field

[0001] The invention relates to the technical field of urea filter element maintenance, and in particular to a urea filter element maintenance reminder method, device, electronic equipment and storage medium. Background Art

[0002] At present, the emission regulations for heavy-duty commercial vehicles have been upgraded to China's sixth stage. The NOx emission requirement for the vehicle PEMS test must be below 0.69g / kWh, which puts higher requirements on the quality and concentration of urea. The concentration of urea is mainly monitored by the urea quality sensor. When the urea concentration is unqualified, the engine emissions will exceed the standard, and the engine will limit torque or even speed. When the quality of urea is poor, for example, the urea contains impurities, although the emissions will not exceed the standard, the impurities in the urea will cause the urea filter to be blocked. The blocked urea filter will cause the urea pump to fail to absorb the liquid, which will eventually lead to the failure of the urea pump to build pressure or even damage the urea pump.

[0003] Therefore, urea filter maintenance is also an important part of engine maintenance, and it may even have a more serious impact on post-processing components than unqualified urea quality, because the blockage of urea filter will cause irreversible damage to urea pump. The final result is often that the urea pump is damaged or leaks due to failure to replace urea filter in time, which is not worth the loss. In addition, since urea filter is installed in urea tank, many customers are unaware of the wearing part of urea filter, so it is very important to remind customers to maintain urea filter in time.

[0004] Therefore, how to remind users to replace urea filter elements in time has become an urgent problem to be solved. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0068] At present, the emission regulations for heavy-duty commercial vehicles have been upgraded to China's sixth stage. The NOx emission requirement for the vehicle PEMS test must be below 0.69g / kWh, which puts higher requirements on the quality and concentration of urea. The concentration of urea is mainly monitored by the urea quality sensor. When the urea concentration is unqualified, the engine emissions will exceed the standard, and the engine will limit torque or even speed. When the quality of urea is poor, for example, the urea contains impurities, although the emissions will not exceed the standard, the impurities in the urea will cause the urea filter to be blocked. The blocked urea filter will cause the urea pump to fail to absorb the liquid, which will eventually lead to the failure of the urea pump to build pressure or even damage the urea pump.

[0069] Therefore, urea filter maintenance is also an important part of engine maintenance, and it may even have a more serious impact on post-processing components than unqualified urea quality, because the blockage of urea filter will cause irreversible damage to urea pump. The final result is often that the urea pump is damaged or leaks due to failure to replace urea filter in time, which is not worth the loss. In addition, since urea filter is installed in urea tank, many customers are unaware of the wearing part of urea filter, so it is very important to remind customers to maintain urea filter in time.

[0070] Therefore, how to remind users to replace urea filter elements in time has become an urgent problem to be solved.

[0071] It should be noted that the method for urea filter maintenance reminder provided in the embodiment of the present application may be implemented by a device for urea filter maintenance reminder, and the device for urea filter maintenance reminder may be implemented as part or all of an electronic device through software, hardware, or a combination of software and hardware, wherein the electronic device may be a control device in the target vehicle. In the following method embodiments, the implementation subject is an electronic device as an example for explanation.

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

[0073] In this embodiment, a urea filter element maintenance reminder method is provided, which can be used in the above-mentioned electronic device. Figure 1 : is a flow chart of a urea filter element maintenance reminder method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0075] Optionally, the electronic device may read the attribute information of the target vehicle from the storage space to determine the vehicle type corresponding to the target vehicle.

[0076] Optionally, the electronic device may also receive a vehicle type corresponding to the target vehicle.

[0077] The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the vehicle type corresponding to the target vehicle.

[0078] Step S102, determining a preset condition corresponding to the target vehicle according to the vehicle type corresponding to the target vehicle.

[0079] Specifically, different vehicle types correspond to different preset conditions, and the electronic device can determine the preset conditions corresponding to the target vehicle according to the corresponding relationship between the vehicle type and the preset conditions.

[0080] This step will be described in detail below.

[0081] Step S103, obtaining parameter information of the target vehicle corresponding to the preset conditions.

[0082] Specifically, the electronic device can read the preset conditions, determine the parameter information of the target vehicle involved in the preset conditions, and then monitor the target vehicle to obtain the parameter information of the target vehicle corresponding to the preset conditions.

[0083] This step will be described in detail below.

[0084] Step S104, detecting whether the parameter information of the target vehicle meets the preset conditions.

[0085] Specifically, the electronic device can read the preset conditions and then detect whether the acquired parameter information of the target vehicle meets the preset conditions.

[0086] This step will be described in detail below.

[0087] Step S105: if the parameter information meets the preset conditions, it is determined that the urea filter element of the target vehicle needs maintenance, and a urea filter element maintenance prompt message is output.

[0088] Specifically, if the parameter information meets the preset conditions, the electronic device determines that the urea filter element of the target vehicle needs maintenance, and outputs urea filter element maintenance prompt information.

[0089] Optionally, the electronic device may display urea filter element maintenance reminder information through a display component in the target vehicle. Optionally, the electronic device may output urea filter element maintenance reminder voice information through a voice output component in the target vehicle.

[0090] The urea filter maintenance reminder method provided in the embodiment of the present application obtains the vehicle type corresponding to the target vehicle; according to the vehicle type corresponding to the target vehicle, the preset conditions corresponding to the target vehicle are determined, thereby ensuring the accuracy of the preset conditions corresponding to the determined target vehicle, so that it is possible to detect whether the target vehicle needs urea filter maintenance based on the preset conditions. Then, the parameter information of the target vehicle corresponding to the preset conditions is obtained; and the parameter information of the target vehicle is detected to see whether it meets the preset conditions, thereby ensuring the accuracy of the obtained detection results. If the parameter information meets the preset conditions, it is determined that the urea filter of the target vehicle needs maintenance, and the urea filter maintenance reminder information is output, thereby realizing timely reminders to the user to perform urea filter maintenance. It avoids untimely maintenance of the urea filter, which affects the normal driving of the engine of the target vehicle.

[0091] In this embodiment, a urea filter element maintenance reminder method is provided, which can be used in the above-mentioned electronic device. Figure 2 : is a flow chart of a urea filter element maintenance reminder method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0092] Step S201, obtaining the vehicle type corresponding to the target vehicle.

[0093] For details about this step, please refer to the above description of step S101, which will not be elaborated here.

[0094] Step S202: determining a preset condition corresponding to the target vehicle according to the vehicle type corresponding to the target vehicle.

[0095] Specifically, the vehicle type includes a road vehicle, and the above step S202 may include the following steps:

[0096] Step S2021: if the target vehicle is a road vehicle, determining that the preset condition corresponding to the target vehicle is the first preset condition.

[0097] Among them, road vehicles can represent vehicles with a large mileage, such as tractors, trucks, logistics vehicles, etc.

[0098] Specifically, the electronic device may determine that the preset condition corresponding to the target vehicle is the first preset condition according to the corresponding relationship between the road vehicle and the first preset condition.

[0099] Step S203, obtaining parameter information of the target vehicle corresponding to the preset conditions.

[0100] Specifically, the above step S203 may include the following steps:

[0101] Step S2031, obtaining the vehicle running mileage, vehicle running time and operating parameters of the urea pump corresponding to the target vehicle.

[0102] Among them, the vehicle mileage and vehicle operating time are the vehicle mileage and vehicle operating time reset after the last maintenance of the urea filter element.

[0103] Specifically, the electronic device can read the current total mileage data stored in the instrument control unit (ECU) and obtain the historical total mileage data corresponding to the last maintenance of the urea filter element. Then, the electronic device uses the current total mileage data to subtract the historical total mileage data to obtain the vehicle running mileage corresponding to the target vehicle.

[0104] The electronic device receives a message including the engine start time and the running time sent by the engine control unit (ECU) each time, and obtains each vehicle sub-running time. The electronic device can add up each vehicle sub-running time after the last maintenance of the urea filter element to obtain the vehicle running time corresponding to the target vehicle.

[0105] Specifically, the electronic device can obtain the operating parameters of the urea pump corresponding to the target vehicle through a communication connection with a sensor installed on the urea pump.

[0106] Step S204, detecting whether the parameter information of the target vehicle meets the preset conditions.

[0107] Specifically, the above step S204 may include the following steps:

[0108] Step S2041, detecting whether the vehicle running mileage is greater than a preset running mileage.

[0109] Specifically, the electronic device may receive the preset running mileage input by the user, or may receive the preset running mileage sent by other devices. The electronic device may also set the preset running mileage according to the current state information of the target vehicle.

[0110] Specifically, the electronic device can obtain the current total mileage and total usage time of the target vehicle. The electronic device can also obtain the historical driving record of the target vehicle, as well as the maintenance record of the target vehicle (detailed to the time, items and replaced parts of each maintenance), the real-time status data of the key components of the vehicle (including engine performance indicators, brake system wear, tire condition, etc.), the use environment data of the target vehicle (such as the type of road conditions and climatic conditions frequently traveled on, etc.) and the driving habit data of the vehicle (average speed, frequency of sudden acceleration and sudden braking, etc.). Then, the electronic device inputs the current total mileage, total usage time, historical driving record, maintenance record, real-time status data of the key components of the vehicle, the use environment data of the target vehicle and the driving habit data of the vehicle into the target preset running mileage calculation model, and the target preset running mileage calculation model extracts features from the input data and outputs the preset running mileage corresponding to the target vehicle.

[0111] Exemplarily, the preset running mileage can be 30,000 kilometers, 31,000 kilometers, or other kilometres. The embodiment of the present application does not specifically limit the preset running mileage.

[0112] Then, the electronic device compares the vehicle running mileage with the preset running mileage to detect whether the vehicle running mileage is greater than the preset running mileage.

[0113] Step S2042, detecting whether the vehicle running time is greater than a preset vehicle running time threshold.

[0114] Specifically, the electronic device may receive a preset vehicle operation time threshold value input by a user, or may receive a preset vehicle operation time threshold value sent by other devices. The electronic device may also set a preset vehicle operation time threshold value according to current status information of the target vehicle.

[0115] Specifically, the electronic device can obtain the current total mileage and total usage time of the target vehicle. The electronic device can also obtain the historical driving record of the target vehicle, as well as the maintenance record of the target vehicle (detailed to the time, items and replaced parts of each maintenance), the real-time status data of the key components of the vehicle (including engine performance indicators, brake system wear, tire condition, etc.), the use environment data of the target vehicle (such as the type of road conditions and climatic conditions frequently traveled on, etc.) and the driving habit data of the vehicle (average speed, frequency of sudden acceleration and sudden braking, etc.). Then, the electronic device inputs the current total mileage, total usage time, historical driving record, maintenance record, real-time status data of the key components of the vehicle, the use environment data of the target vehicle and the driving habit data of the vehicle into the target preset vehicle operation time threshold calculation model, and the target preset vehicle operation time threshold calculation model extracts features from the input data and outputs the preset vehicle operation time threshold corresponding to the target vehicle.

[0116] Exemplarily, the preset vehicle operating time threshold may be 6 months, 5 months, or other durations. The embodiment of the present application does not specifically limit the preset vehicle operating time threshold.

[0117] Step S2043, detecting whether the operating parameters meet the preset operating parameter conditions.

[0118] Specifically, the operating parameters include the current speed of the urea pump. The above step S2043 may include the following steps:

[0119] Step a1, obtaining the current speed corresponding to the urea pump.

[0120] Specifically, the electronic device may obtain the current rotation speed corresponding to the urea pump based on a rotation speed sensor installed on the urea pump.

[0121] Step a2, comparing the current rotation speed with a preset rotation speed threshold.

[0122] Specifically, the electronic device can receive a preset speed threshold input by a user, or a preset speed threshold sent by other devices, or a preset speed threshold sent by other devices. The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the preset speed threshold.

[0123] Exemplarily, the preset speed threshold may be 3900 rpm, or 4000 rpm, or other values. The embodiment of the present application does not specifically limit the preset speed threshold.

[0124] The electronics then compare the current speed with a preset speed threshold.

[0125] Step a3: if the current rotation speed is greater than the preset rotation speed threshold, it is determined that the operating parameters meet the preset operating parameter conditions.

[0126] In an optional implementation, if the current rotation speed is greater than a preset rotation speed threshold, the electronic device determines that the operating parameter meets a preset operating parameter condition.

[0127] For example, Figure 3 As shown in the figure, it is a framework diagram of the maintenance reminder method of the urea filter element for high-speed standard-load highway vehicles. Figure 3 As shown, the main input quantities include: vehicle mileage, vehicle running time and urea pump speed. When the vehicle mileage exceeds 30,000 kilometers, the vehicle running time exceeds 6 months or the urea pump speed exceeds 3900 rpm, the urea pump maintenance status is set to 1, and the DCU sends a urea filter maintenance reminder message to the bus. The instrument parses the message content and synchronously displays "Please maintain the urea filter and liquid level sensor filter" on the instrument.

[0128] When the urea filter element and liquid level filter are maintained, they are reset through the diagnostic instrument, and the current vehicle mileage and vehicle running time are reset to an intermediate value written into the memory. The vehicle mileage and vehicle running time are cleared, the filter element maintenance reminder counter starts counting again, the DCU sends the message content reset, and the instrument text prompt disappears.

[0129] In another optional implementation, the operating parameter further includes a pressure difference of a urea pump; the above step a3 may include the following steps:

[0130] Step a31, detecting whether the corresponding liquid inlet pressure and liquid outlet pressure of the urea pump are both within the corresponding preset pressure range.

[0131] Specifically, the electronic device can continuously monitor the inlet pressure and outlet pressure corresponding to the urea pump according to a preset sampling frequency based on high-precision pressure sensors installed in the inlet pipe and outlet pipe of the urea pump.

[0132] Then, the electronic device compares the real-time collected inlet pressure and outlet pressure values ​​with the corresponding preset pressure ranges. If the inlet pressure value is within the corresponding preset range, and the outlet pressure value is also within the corresponding preset range, it is determined that the inlet pressure and outlet pressure of the urea pump are both in normal state;

[0133] If the inlet pressure value exceeds the corresponding preset range or the outlet pressure value exceeds the corresponding preset range, it is determined that the pressure of the urea pump is abnormal and further inspection and processing are required.

[0134] For example, the electronic device can receive the preset pressure ranges corresponding to the inlet pressure and outlet pressure input by the user. For example, the preset range of the inlet pressure of a urea pump of a certain brand of vehicle may be 3-5 bar, and the preset range of the outlet pressure may be 8-12 bar. If the inlet pressure is continuously lower than 3 bar or higher than 5 bar, or the outlet pressure is continuously lower than 8 bar or higher than 12 bar, it is necessary to check the urea pump and its related pipelines to see if there are problems such as blockage, leakage, pump body failure, etc.

[0135] Step a32: if the inlet pressure and outlet pressure corresponding to the urea pump are both within the corresponding preset pressure range, and the current speed is greater than the preset speed threshold, then the inlet pressure and outlet pressure corresponding to the urea pump are obtained.

[0136] Specifically, if the inlet pressure and outlet pressure corresponding to the urea pump are both within the corresponding preset pressure range, and the current speed of the urea pump is greater than the preset speed threshold, the electronic device collects the inlet pressure and outlet pressure corresponding to the urea pump again based on the high-precision pressure sensors installed in the inlet and outlet pipes of the urea pump.

[0137] Step a33, calculating the pressure difference between the liquid inlet pressure and the liquid outlet pressure.

[0138] Specifically, the electronic device uses the liquid outlet pressure to subtract the liquid inlet pressure to obtain the pressure difference.

[0139] Step a34, comparing the pressure difference with a preset pressure difference threshold.

[0140] Specifically, the electronic device can receive a preset pressure difference threshold value input by a user, or a preset pressure difference threshold value sent by other devices. The electronic device can also determine the preset pressure difference threshold value corresponding to the urea pump based on the property information of the urea pump. For example, for a certain type of urea pump, the pressure difference before and after the filter element is generally between 0.1-0.3 bar during normal operation. Then, the electronic device compares the pressure difference with the preset pressure difference threshold value.

[0141] Step a35, if the pressure difference is greater than the preset pressure difference threshold, then record the first duration of the pressure difference being greater than the preset pressure difference threshold, and record the second duration of the current rotation speed being greater than the preset rotation speed threshold.

[0142] Specifically, if the pressure difference is greater than the preset pressure difference threshold, a first duration during which the pressure difference is greater than the preset pressure difference threshold is recorded, and a second duration during which the current rotation speed is greater than the preset rotation speed threshold is recorded.

[0143] Step a36: If the first duration is greater than the first preset duration, and / or the second duration is greater than the second preset duration, it is determined that the operating parameter meets the preset operating parameter condition.

[0144] Specifically, the electronic device may receive a first preset duration and a second preset duration input by a user. Then, the electronic device compares the first duration with the first preset duration, and compares the second duration with the second preset duration. If the first duration is greater than the first preset duration, and / or the second duration is greater than the second preset duration, it is determined that the operating parameter meets the preset operating parameter condition.

[0145] Step S2044, if the vehicle running mileage is greater than the preset running mileage, and / or the vehicle running time is greater than the preset vehicle running time threshold, and / or the running parameters meet the preset running parameter conditions, it is determined that the parameter information of the target vehicle meets the preset conditions.

[0146] Specifically, if the vehicle running mileage is greater than the preset running mileage, and / or the vehicle running time is greater than the preset vehicle running time threshold, and / or the running parameters meet the preset running parameter conditions, it is determined that the parameter information of the target vehicle meets the preset conditions.

[0147] Step S205: If the parameter information meets the preset conditions, it is determined that the urea filter element of the target vehicle needs maintenance, and a urea filter element maintenance prompt message is output.

[0148] In an optional implementation of the present application, after a preset time period after outputting the urea filter maintenance reminder information, the electronic device obtains the current speed and the inlet and outlet pressures corresponding to the urea pump, and calculates the pressure difference between the inlet and outlet pressures. If the current speed is less than the preset speed threshold, and the pressure difference is less than the preset pressure difference threshold, the electronic device determines that the urea filter has been maintained. The electronic device records the current total mileage corresponding to when the urea filter has been maintained, and resets the vehicle running time.

[0149] The urea filter element maintenance reminder method provided in the embodiment of the present application, if the target vehicle is a road vehicle, determines that the preset condition corresponding to the target vehicle is the first preset condition; then, obtains the vehicle mileage, vehicle running time and operating parameters of the urea pump corresponding to the target vehicle, ensuring the accuracy of the obtained vehicle mileage, vehicle running time and operating parameters of the urea pump corresponding to the target vehicle. Then, it can be determined that the urea filter element of the target vehicle needs maintenance based on the vehicle mileage, vehicle running time and operating parameters of the urea pump. Detect whether the vehicle mileage is greater than the preset mileage; detect whether the vehicle running time is greater than the preset vehicle running time threshold; obtain the current speed corresponding to the urea pump; compare the current speed with the preset speed threshold; if the current speed is greater than the preset speed threshold, detect whether the corresponding inlet pressure and outlet pressure of the urea pump are both within the corresponding preset pressure range, so that it can be detected whether the corresponding inlet pressure and outlet pressure of the urea pump are in a stable state. If the inlet pressure and outlet pressure corresponding to the urea pump are both within the corresponding preset pressure range, it is determined that the inlet pressure and outlet pressure corresponding to the urea pump are in a stable state, and the current speed is greater than the preset speed threshold, then the inlet pressure and outlet pressure corresponding to the urea pump are obtained, ensuring the accuracy of the obtained inlet pressure and outlet pressure corresponding to the urea pump. Calculate the pressure difference between the inlet pressure and the outlet pressure; compare the pressure difference with the preset pressure difference threshold; if the pressure difference is greater than the preset pressure difference threshold, record the first duration of the pressure difference greater than the preset pressure difference threshold, and record the second duration of the current speed greater than the preset speed threshold, so that it can be detected whether the operating parameters meet the preset operating parameter conditions according to the first duration and the second duration. If the first duration is greater than the first preset duration, and / or the second duration is greater than the second preset duration, it is determined that the operating parameters meet the preset operating parameter conditions, ensuring the accuracy of the determined operating parameters meeting the preset operating parameter conditions. If the vehicle's mileage is greater than the preset mileage, and / or the vehicle's running time is greater than the preset vehicle running time threshold, and / or the operating parameters meet the preset operating parameter conditions, then the parameter information of the target vehicle is determined to meet the preset conditions, ensuring the accuracy of the parameter information of the determined target vehicle meeting the preset conditions. Based on the vehicle's mileage, vehicle running time, and the operating parameters of the urea pump, the method determines that the urea filter element of the target vehicle needs maintenance and outputs urea filter element maintenance reminder information. This ensures the timeliness of outputting the urea filter element maintenance reminder information.

[0150] In this embodiment, a urea filter element maintenance reminder method is provided, which can be used in the above-mentioned electronic device. Figure 4 : is a flow chart of a urea filter element maintenance reminder method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0151] Step S301, obtaining the vehicle type corresponding to the target vehicle.

[0152] For details about this step, please refer to the above description of step S201, which will not be elaborated here.

[0153] Step S302: determining a preset condition corresponding to the target vehicle according to the vehicle type corresponding to the target vehicle.

[0154] Specifically, the vehicle type includes an engineering vehicle, and the above step S302 may include the following steps:

[0155] Step S3021: If the target vehicle is an engineering vehicle, determine that the preset condition corresponding to the target vehicle is the second preset condition.

[0156] Among them, engineering vehicles are used to represent vehicles with more operating states and less mileage, such as mixer trucks, muck trucks, pump trucks, cranes, etc.

[0157] Specifically, the electronic device may determine that the preset condition corresponding to the target vehicle is the second preset condition according to the corresponding relationship between the engineering vehicle and the second preset condition.

[0158] Step S303, obtaining parameter information of the target vehicle corresponding to the preset conditions.

[0159] Specifically, the above step S303 may include the following steps:

[0160] Step S3031, obtaining the urea pump operation time, vehicle operation time and operation parameters of the urea pump corresponding to the target vehicle.

[0161] The urea pump operating time and the vehicle operating time are the urea pump operating time and the vehicle operating time reset after the last maintenance of the urea filter element.

[0162] Specifically, the electronic device can read the current total mileage data stored in the instrument control unit (ECU) and obtain the historical total mileage data corresponding to the last maintenance of the urea filter element. Then, the electronic device uses the current total mileage data to subtract the historical total mileage data to obtain the vehicle running mileage corresponding to the target vehicle.

[0163] Specifically, the electronic device receives a message including the urea pump start time and the running time sent by the engine control unit (ECU) each time, and obtains each urea pump running time. The electronic device can add up each urea pump running time after the last maintenance of the urea filter element to obtain the urea pump running time corresponding to the target vehicle.

[0164] Specifically, the electronic device can obtain the operating parameters of the urea pump corresponding to the target vehicle through a communication connection with a sensor installed on the urea pump.

[0165] Step S304, detecting whether the parameter information of the target vehicle meets the preset conditions.

[0166] Specifically, the above step S304 may include the following steps:

[0167] Step S3041, detecting whether the urea pump operation time is greater than a preset urea pump operation time threshold.

[0168] Specifically, the electronic device may receive a preset urea pump operation time threshold value input by a user, or may receive a preset urea pump operation time threshold value sent by other devices. The electronic device may also set a preset urea pump operation time threshold value according to current state information of the target vehicle.

[0169] Specifically, the electronic device can obtain the current total mileage and total usage time of the target vehicle, and the electronic device can also obtain the historical driving record of the target vehicle, and then input the current total mileage, total usage time and historical driving record of the target vehicle into the target preset urea pump operation time threshold calculation model, and the target preset urea pump operation time threshold calculation model extracts features from the current total mileage, total usage time and historical driving record of the target vehicle, and outputs the preset urea pump operation time threshold corresponding to the target vehicle. Among them, the preset urea pump operation time threshold corresponding to the target vehicle can be updated according to the current total mileage, total usage time and historical driving record of the target vehicle.

[0170] Exemplarily, the preset urea pump operation time threshold may be 600 hours, or 580 hours, or other durations. The embodiment of the present application does not specifically limit the preset urea pump operation time threshold.

[0171] Then, the electronic device compares the urea pump operation time with a preset urea pump operation time threshold value to detect whether the urea pump operation time is greater than the preset urea pump operation time threshold value.

[0172] Step S3042, detecting whether the vehicle running time is greater than a preset vehicle running time threshold.

[0173] For details about this step, please refer to the above description of step S2042 and will not be repeated here.

[0174] Step S3043, detecting whether the operating parameters meet the preset operating parameter conditions.

[0175] For details about this step, please refer to the above description of step S2043, which will not be repeated here.

[0176] Step S3044: if the urea pump operation time is greater than the preset urea pump operation time threshold, and / or the vehicle operation time is greater than the preset vehicle operation time threshold, and / or the operation parameter meets the preset operation parameter condition, it is determined that the parameter information of the target vehicle meets the preset condition.

[0177] Specifically, if the urea pump operating time is greater than a preset urea pump operating time threshold, and / or the vehicle operating time is greater than a preset vehicle operating time threshold, and / or the operating parameters meet the preset operating parameter conditions, it is determined that the parameter information of the target vehicle meets the preset conditions.

[0178] Step S305: If the parameter information meets the preset conditions, it is determined that the urea filter element of the target vehicle needs maintenance, and a urea filter element maintenance prompt message is output.

[0179] For details about this step, please refer to the above description of step S205, which will not be elaborated here.

Figure 5 As shown, the main input quantities include: urea pump operation time, vehicle operation time and urea pump speed. When the urea pump operation time exceeds 600 hours, the vehicle operation time exceeds 2 months or the urea pump speed exceeds 3900 rpm, the urea pump maintenance status is set to 1, and the DCU sends a urea filter maintenance reminder message to the bus. The instrument parses the message content and synchronously displays "Please maintain the urea filter and liquid level sensor filter" on the instrument. When the urea filter and liquid level filter are maintained, they are reset through the diagnostic instrument, and the current vehicle mileage and vehicle operation time are reset to an intermediate value written to the memory. The vehicle mileage and vehicle operation time are cleared, the filter maintenance reminder counter starts counting again, the DCU sends the message content reset, and the instrument text prompt disappears.

[0181] In an optional implementation of the present application, after a preset time period after outputting the urea filter maintenance reminder information, the electronic device obtains the current speed and the inlet and outlet pressures corresponding to the urea pump, and calculates the pressure difference between the inlet and outlet pressures. If the current speed is less than the preset speed threshold, and the pressure difference is less than the preset pressure difference threshold, the electronic device determines that the urea filter has been maintained. The electronic device records the current total mileage corresponding to when the urea filter has been maintained, and resets the vehicle running time.

Obtain the urea pump operation time, vehicle operation time and operation parameters of the urea pump corresponding to the target vehicle, and ensure the accuracy of the acquired urea pump operation time, vehicle operation time and operation parameters of the urea pump corresponding to the target vehicle, so that the urea filter element of the target vehicle needs maintenance according to the urea pump operation time, vehicle operation time and operation parameters of the urea pump corresponding to the target vehicle, and output urea filter element maintenance reminder information. Detect whether the urea pump operation time is greater than the preset urea pump operation time threshold; detect whether the vehicle operation time is greater than the preset vehicle operation time threshold; detect whether the operation parameters meet the preset operation parameter conditions; if the urea pump operation time is greater than the preset urea pump operation time threshold, and / or the vehicle operation time is greater than the preset vehicle operation time threshold, and / or the operation parameters meet the preset operation parameter conditions, then determine that the parameter information of the target vehicle meets the preset conditions, and ensure the accuracy of the determined parameter information of the target vehicle meeting the preset conditions.
