In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0032] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Figures 1 to 6 The vehicle power system oil replacement reminder method of the present invention is described.

[0033] Figure 1 FIG. 1 is a flow chart of a method for reminding a vehicle power system to change oil provided by the present invention. Figure 1 As shown, the method includes the following steps 101 to 108.

[0034] In practical applications, the execution subject of the vehicle power system oil replacement reminder method can be a vehicle power system oil replacement reminder device, which can be implemented in many ways, for example, it can be implemented through a computer program, such as application software, etc.; or, for example, a chip, etc. It can also be implemented as a medium storing relevant computer programs, such as a U disk, a cloud disk, etc.; or, it can also be implemented through a physical device integrated or installed with relevant computer programs, such as a server, etc.

[0035] Step 101: Determine the current mileage correction interval time according to the current vehicle speed.

[0036] In practical applications, the vehicle speed can be acquired in real time through a vehicle speed sensor or other vehicle-mounted systems, and the mileage correction interval is dynamically determined based on the vehicle's current speed.

[0037] The mileage correction interval refers to the time period used to calculate and correct the mileage during the vehicle's driving process. In this embodiment, the mileage correction interval is dynamically determined according to the vehicle speed. For example, when the vehicle is driving at high speed, the speed is relatively stable and the fuel consumption changes slightly. A longer time interval (such as 15 minutes) can be set to calculate and correct the mileage. In contrast, when the vehicle is driving at low speed or in the city, the speed changes frequently and the fuel consumption fluctuates greatly. A shorter time interval (such as 5 minutes) needs to be set to more accurately calculate and correct the mileage.

[0038] It can be understood that by reasonably setting and dynamically adjusting the mileage correction interval, it can be ensured that the oil change reminder system can provide accurate and timely reminders under various driving conditions, helping users to better maintain the vehicle power system, extend its service life and maintain good performance.

[0039] Optionally, the vehicle speed is one of the main bases for determining the mileage correction interval. In addition, the current mileage correction interval can also be determined based on the vehicle's operating status parameters, such as acceleration, deceleration, climbing, congestion, etc.

[0040] Step 102: Calculate the actual mileage of the vehicle at the current mileage correction interval.

[0041] The actual mileage refers to the total distance actually traveled by the vehicle at the current mileage correction interval, usually in kilometers or miles. In practical applications, the calculated actual mileage will be used for subsequent mileage correction calculations. The actual mileage is corrected by combining the mileage correction factor and the oil change cycle factor to obtain a more accurate corrected mileage.

[0042] Specifically, the actual mileage under the current mileage correction interval can be calculated based on the current vehicle speed and the current mileage correction interval. For example, the actual mileage can be obtained by calculating the product of the current vehicle speed and the current mileage correction interval.

[0043] Step 103: Detect the operating condition type under the current mileage correction interval time.

[0044] As an example, the types of operating conditions involved in the present invention include but are not limited to: light-load operating conditions, heavy-load operating conditions, high-speed operating conditions, low-speed operating conditions, and severe operating conditions. Among them, light-load operating conditions refer to the vehicle load being light and driving smoothly. Heavy-load operating conditions refer to the vehicle load being heavy and may require greater power output. High-speed operating conditions refer to the vehicle driving at a higher speed, such as on a highway. Low-speed operating conditions refer to the vehicle driving at a lower speed, possibly on urban roads or congested roads. Severe operating conditions refer to conditions that are unfavorable to vehicle operation, such as extreme weather and complex road conditions.

[0045] Specifically, the present invention does not make any specific limitation on the detection of the operating condition type. In one example, an operating condition detection device is provided on the vehicle, and the operating condition detection device comprehensively evaluates the operating condition type under the current mileage correction interval time by combining data such as vehicle speed, engine speed, fuel consumption and ambient temperature. In another example, the operating condition detection device obtains GPS and navigation data, analyzes the vehicle's driving route based on the GPS and navigation data, and can detect the operating condition type under the current mileage correction interval time. In yet another example, the operating condition type of the vehicle can be inferred based on the vehicle's driving mode (such as economy mode, sports mode, etc.). For example, the vehicle may be in a high-load, high-speed operating condition in sports mode.

[0046] Optionally, for the detection method of the working condition type, in a possible implementation manner, the above step 103 includes: Calculate the average fuel consumption per 100 kilometers at the current mileage correction interval; The current operating condition type of the vehicle is determined based on the fuel consumption range of the average fuel consumption per 100 kilometers, and the fuel consumption range corresponds to the operating condition type one by one.

[0047] Specifically, the instantaneous fuel consumption per 100 kilometers at each moment within the current mileage correction interval is obtained. The instantaneous fuel consumption per 100 kilometers refers to the amount of fuel consumed by the vehicle for every 100 kilometers traveled at a certain moment or in a short period of time, usually in liters / 100 kilometers (L / 100km). It is one of the important indicators for measuring the fuel economy of a vehicle and can reflect the fuel consumption of the vehicle under specific driving conditions. For example, the instantaneous fuel consumption per 100 kilometers can be calculated based on the fuel flow and vehicle speed, and the instantaneous fuel consumption per 100 kilometers can also be calculated based on the fuel consumption and driving distance.

[0048] Furthermore, the average value of the instantaneous fuel consumption per 100 kilometers at all times within the current mileage correction interval is calculated to obtain the average fuel consumption per 100 kilometers within the current mileage correction interval. Optionally, when the current mileage correction interval is short, the instantaneous fuel consumption per 100 kilometers can be used as the average fuel consumption per 100 kilometers.

[0049] Furthermore, the current operating condition type of the vehicle is determined based on the fuel consumption range of the average fuel consumption per 100 kilometers, and the fuel consumption range corresponds to the operating condition type one by one.

[0050] For example, multiple fuel consumption ranges can be set from low to high, and each fuel consumption range corresponds to a working condition type. Specifically, after calculating the average fuel consumption per 100 kilometers, the fuel consumption range to which the average fuel consumption per 100 kilometers belongs is determined, and the working condition type corresponding to the fuel consumption range is used as the current working condition type of the vehicle.

[0051] Step 104: Determine the mileage correction coefficient at the current mileage correction interval according to the operating condition type.

[0052] The mileage correction factor represents the change in the oil deterioration rate under the corresponding operating condition type (or fuel consumption level). It can be understood that the mileage correction factor is used to adjust the actual mileage to reflect the actual degree of oil deterioration.

[0053] Specifically, from multiple operating condition types, a reference operating condition type is set, and the mileage correction factor corresponding to the reference operating condition type is set as a fixed reference value. The remaining operating condition types are compared with the reference operating condition type to calculate the corresponding mileage correction factor. For example, four fuel consumption ranges are set from low to high, and each fuel consumption range corresponds to a working condition type, that is, four working condition types are set, and the light load working condition is set as the reference working condition type, and the mileage correction factor corresponding to the light load working condition is set to 0. The remaining three working condition types are compared with the reference working condition type to calculate the corresponding mileage correction factor.

[0054] In this embodiment, there is no specific limitation on the calculation method of the mileage correction coefficient corresponding to the other operating condition types. In one example, the mileage correction coefficient is set to a fixed value for each operating condition type. For example, the mileage correction coefficient corresponding to the reference operating condition type is set to 0, and different values ​​are set for the other three operating condition types. In another example, the mileage correction coefficients corresponding to the other operating condition types can be dynamically calculated, and these coefficients can be dynamically adjusted based on the real-time monitored fuel consumption data and a preset calculation formula. For example, a linear or nonlinear function can be used to describe the relationship between fuel consumption and the mileage correction coefficient, and the corresponding mileage correction coefficient can be calculated based on the real-time fuel consumption data.

[0055] Step 105: For each power unit in the vehicle power system, determine the oil replacement cycle coefficient corresponding to the power unit according to the type of vehicle and the model of the power unit.

[0056] In this embodiment, the vehicle power system includes a plurality of power devices. For example, the power devices in the vehicle power system include, but are not limited to, an engine, a gearbox, and a drive axle. Accordingly, the models of the power devices include, but are not limited to, an engine model, a gearbox model, and a drive axle model.

[0057] Specifically, the oil replacement cycle coefficient is determined according to the type of vehicle and the model of the power unit. It is understood that the oil replacement cycle coefficient is used to correct the actual mileage to adapt to the characteristics of different vehicles and power system devices.

[0058] In actual applications, the vehicle type and the power unit do not change during the operation of the vehicle. Optionally, the oil replacement cycle coefficient can be determined according to either the vehicle type or the power unit model. Optionally, when the vehicle type and the power system device do not change, the oil replacement cycle coefficient can be set to a fixed value in advance.

[0059] Optionally, in a possible implementation manner, the above step 105 specifically includes: Based on the type of vehicle and the model of the power unit, the MAP diagram is queried to obtain the oil replacement cycle coefficient corresponding to the power unit; wherein the MAP diagram is a corresponding relationship diagram between different vehicle types and different power unit models and the oil replacement cycle coefficient.

[0060] For example, there are m types of vehicles and n types of power unit models. Create an m times n MAP diagram (Matrix diagram). Based on the reference vehicle type and reference power unit model, the corresponding oil change cycle coefficient is 1. The remaining mn-1 types are compared with the basic value to calculate the corresponding oil change cycle coefficient.

[0061] First, define the MAP diagram. Specifically, establish an m×n matrix, where m represents the number of different vehicle types and n represents the number of different power unit models.

[0062] Further, a reference vehicle type and a reference power unit model are selected, and the combination of the reference vehicle type and the reference power unit model is taken as the basic value, and the corresponding oil change cycle coefficient is set to 1. This means that the oil change cycle of this basic combination does not need any adjustment.

[0063] Furthermore, for the remaining mn-1 combinations of vehicle types and power system device models in the MAP diagram, each needs to be compared with the base value to calculate the corresponding oil change cycle coefficient. For example, the calculation of the oil change cycle coefficient may be based on experimental data, statistical analysis, or expert experience to determine the specific impact of different vehicle types and power system device models on the oil change cycle.

[0064] On this basis, based on the type of vehicle and the model of the power unit, the oil change cycle coefficient corresponding to the power unit can be obtained by querying the MAP diagram.

[0065] Step 106: Based on the mileage correction coefficient at the current mileage correction interval and the oil replacement cycle coefficient corresponding to the power device, the actual mileage is corrected to obtain the corrected mileage corresponding to the power device at the current mileage correction interval.

[0066] Specifically, in a possible implementation manner, the above step 106 specifically includes: The product of the mileage correction coefficient at the current mileage correction interval, the oil replacement cycle coefficient corresponding to the power unit and the actual mileage is calculated to obtain the corrected mileage corresponding to the power unit at the current mileage correction interval.

[0067] Combined with the above description, the mileage correction factor is determined based on the current operating condition type, and the oil change cycle coefficient is determined based on the type of vehicle and the model of the power unit. Based on the mileage correction factor and the oil change cycle coefficient, the actual mileage is double-corrected, and the corrected mileage obtained can more comprehensively evaluate the actual deterioration of the oil. It can be understood that the mileage correction factor ensures the equivalence of mileage under different operating conditions, while the oil change cycle coefficient ensures the adaptability of the oil change cycle. The combined use of these two coefficients improves the accuracy of the oil change reminder, ensuring that the user is reminded to change the oil when it is about to reach the degradation limit.

[0068] It is understandable that based on the mileage correction coefficient and the oil change cycle coefficient corresponding to the power unit, the actual mileage is corrected to obtain the corrected mileage, and the mileage of different working conditions, different vehicles, and different power units can be corrected to a unified evaluation level, so that it is possible to accurately judge whether an oil change reminder is needed based on the corrected mileage. It can be seen that the vehicle power system oil change reminder method of the present application can meet the oil change reminder requirements of different working conditions, different vehicles, and different power units, and improve the accuracy and reliability of the oil change reminder.

[0069] Step 107: After the current driving process is completed, the total corrected mileage corresponding to the power device after the previous driving process is completed and the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process are accumulated and calculated to obtain the total corrected mileage corresponding to the power device after the current driving process is completed.

[0070] In practical applications, after each driving process, the total corrected mileage corresponding to the power device is updated. Specifically, before the vehicle starts the current driving process, the vehicle is powered on and the total corrected mileage corresponding to the power device after the last driving process is read. Furthermore, after the current driving process is completed, the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process is obtained. Furthermore, the total corrected mileage corresponding to the power device after the last driving process is completed and the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process are accumulated and calculated to obtain the total corrected mileage corresponding to the power device after the current driving process is completed.

[0071] Optionally, during each driving process, the corrected mileage corresponding to the power device at each mileage correction interval is cached, so that after the driving is completed, the corrected mileage corresponding to the power device at all mileage correction intervals during the driving process can be obtained.

[0072] Optionally, in a possible implementation manner, after the above step 107, the above method further includes: After the current driving process is completed, the total corrected mileage corresponding to the power unit is stored.

[0073] In this embodiment, after the current driving process is completed, the total corrected mileage corresponding to the power unit is stored so that the total corrected mileage corresponding to the power unit after the last driving process is read after the next power-on, thereby accumulating and updating the total corrected mileage, thereby improving the accuracy and reliability of the oil change reminder.

[0074] Step 108: If the total corrected mileage corresponding to the power unit after the current driving process has reached a preset replacement mileage, an oil replacement prompt message is output to the user.

[0075] The preset replacement mileage refers to the oil replacement cycle mileage determined based on factors such as vehicle type, power unit model, oil type, and the maintenance cycle recommended by the manufacturer. The purpose of determining the preset replacement mileage is to ensure that the oil is used in the best condition, extend the service life of the power unit, and maintain the performance of the vehicle.

[0076] For example, the preset replacement mileage of the engine oil of a vehicle is 10,000 kilometers. After the current driving, the total corrected mileage of the engine reaches 10,500 kilometers, and the oil replacement reminder information is output to the user.

[0077] It can be understood that by comparing the total corrected mileage corresponding to the power unit with the preset replacement mileage, if the total corrected mileage reaches or exceeds the preset replacement mileage, the oil change reminder is triggered, which can remind the user to change the oil in time to ensure that the power unit operates in the best condition, thereby extending the service life of the power unit and maintaining vehicle performance.

[0078] Specifically, in a possible implementation manner, outputting the oil replacement prompt information to the user in the above step 108 specifically includes: The oil change reminder information is sent to the instrument panel so that the instrument panel displays the oil change reminder information to the user; wherein the oil change reminder information includes: the total corrected mileage corresponding to the power unit after the end of this driving process, the estimated remaining mileage or estimated remaining time before the next oil change, and the model of the power unit.

[0079] In this embodiment, the oil change reminder information is sent to the instrument panel and displayed to the user, and the reminder information includes details such as the total corrected mileage, the estimated remaining mileage or time, the power unit model, etc. The user can intuitively see the total corrected mileage corresponding to the power unit after the current driving process through the instrument panel, and clearly understand the current oil usage and mileage without additional query or calculation, which improves the convenience and intuitiveness of information acquisition. Optionally, in a possible implementation manner, the above method further includes: At each oil change, the total corrected mileage corresponding to the power unit is initialized to zero.

[0080] In this embodiment, after each oil change, the oil usage of the power unit starts over, and initializing the total corrected mileage to zero can ensure that the calculation of the next oil change cycle starts from zero, avoiding cumulative errors and improving the accuracy and reliability of the oil change reminder.

[0081] In order to better understand the vehicle power system oil replacement reminder method of the present application, it is described below with reference to specific examples.

[0082] Specifically, a real vehicle test was conducted under half-load conditions with the vehicle speed varying between 50km / h and 80km / h to verify the effectiveness of the vehicle power system oil replacement reminder method of the present application. The power device in the vehicle power system includes: an engine, a gearbox and a drive axle. Among them, Figure 2 It is a schematic diagram of the change of the mileage provided by the present invention. Figure 3 It is a schematic diagram of the change of fuel consumption provided by the present invention. Figure 4 This is a total mileage correction effect diagram of the engine oil change reminder system provided by the present invention. Figure 5It is a total mileage correction effect diagram of the transmission oil replacement reminder system provided by the present invention. Figure 6 It is a total mileage correction effect diagram of the drive axle oil replacement reminder system provided by the present invention.

[0083] In the vehicle power system oil replacement reminder method provided in this embodiment, the actual mileage is corrected by comprehensively considering multiple factors such as vehicle speed, working condition type, vehicle type and power unit model to obtain the corrected mileage. The corrected mileage can more accurately reflect the actual use and deterioration degree of the oil. Further, after each driving, the total corrected mileage is updated, and it is determined whether the total corrected mileage reaches the preset replacement mileage. If the preset replacement mileage is reached, the oil replacement reminder information is output to the user, thereby improving the accuracy of the oil replacement reminder. Furthermore, accurate oil replacement reminders ensure that the oil is replaced in time when it approaches the degradation limit, avoiding the increased wear of power system components caused by oil degradation, thereby extending the service life of components such as the engine, gearbox, and drive axle, and improving the stability and safety of the vehicle system. In summary, it can be seen that the solution of this embodiment improves the accuracy of the oil replacement reminder, thereby improving the stability and safety of the vehicle system.

[0084] The vehicle power system oil replacement reminder device provided by the present invention is described below. The vehicle power system oil replacement reminder device described below and the vehicle power system oil replacement reminder method described above can correspond to each other.

[0085] In practical applications, there are many ways to implement the vehicle power system oil replacement reminder device, for example, it can be implemented through a computer program, such as application software, etc.; or, for example, a chip, etc. It can also be implemented as a medium storing relevant computer programs, such as a USB disk, a cloud disk, etc.; or it can also be implemented through a physical device integrated or installed with relevant computer programs, such as a server, etc.

[0086] Figure 7 FIG. 1 is a schematic diagram of the structure of the vehicle power system oil replacement reminder device provided by the present invention. Figure 7 As shown, the vehicle power system oil replacement reminder device includes: a first determination module 71, a calculation module 72, a detection module 73, a second determination module 74, a third determination module 75, a correction module 76, an accumulation module 77 and a prompt module 78.

[0087] The first determination module 71 is used to determine the current mileage correction interval according to the current vehicle speed.

[0088] In practical applications, the vehicle speed can be acquired in real time through a vehicle speed sensor or other vehicle-mounted systems, and the mileage correction interval is dynamically determined based on the vehicle's current speed.

[0089] The mileage correction interval refers to the time period used to calculate and correct the mileage during the vehicle's driving process. In this embodiment, the mileage correction interval is dynamically determined according to the vehicle speed. For example, when the vehicle is driving at high speed, the speed is relatively stable and the fuel consumption changes slightly. A longer time interval (such as 15 minutes) can be set to calculate and correct the mileage. In contrast, when the vehicle is driving at low speed or in the city, the speed changes frequently and the fuel consumption fluctuates greatly. A shorter time interval (such as 5 minutes) needs to be set to more accurately calculate and correct the mileage.

[0090] It can be understood that by reasonably setting and dynamically adjusting the mileage correction interval, it can be ensured that the oil change reminder system can provide accurate and timely reminders under various driving conditions, helping users to better maintain the vehicle power system, extend its service life and maintain good performance.

[0091] Optionally, the vehicle speed is one of the main bases for determining the mileage correction interval. In addition, the current mileage correction interval can also be determined based on the vehicle's operating status parameters, such as acceleration, deceleration, climbing, congestion, etc.

[0092] The calculation module 72 is used to calculate the actual mileage of the vehicle at the current mileage correction interval.

[0093] The actual mileage refers to the total distance actually traveled by the vehicle at the current mileage correction interval, usually in kilometers or miles. In practical applications, the calculated actual mileage will be used for subsequent mileage correction calculations. The actual mileage is corrected by combining the mileage correction factor and the oil change cycle factor to obtain a more accurate corrected mileage.

[0094] Specifically, the actual mileage under the current mileage correction interval can be calculated based on the current vehicle speed and the current mileage correction interval. For example, the actual mileage can be obtained by calculating the product of the current vehicle speed and the current mileage correction interval.

[0095] The detection module 73 is used to detect the operating condition type under the current mileage correction interval.

[0096] As an example, the types of operating conditions involved in the present invention include but are not limited to: light-load operating conditions, heavy-load operating conditions, high-speed operating conditions, low-speed operating conditions, and severe operating conditions. Among them, light-load operating conditions refer to the vehicle load being light and driving smoothly. Heavy-load operating conditions refer to the vehicle load being heavy and may require greater power output. High-speed operating conditions refer to the vehicle driving at a higher speed, such as on a highway. Low-speed operating conditions refer to the vehicle driving at a lower speed, possibly on urban roads or congested roads. Severe operating conditions refer to conditions that are unfavorable to vehicle operation, such as extreme weather and complex road conditions.

[0097] Specifically, the present invention does not make any specific limitation on the detection of the operating condition type. In one example, an operating condition detection device is provided on the vehicle, and the operating condition detection device comprehensively evaluates the operating condition type under the current mileage correction interval time by combining data such as vehicle speed, engine speed, fuel consumption and ambient temperature. In another example, the operating condition detection device obtains GPS and navigation data, analyzes the vehicle's driving route based on the GPS and navigation data, and can detect the operating condition type under the current mileage correction interval time. In yet another example, the operating condition type of the vehicle can be inferred based on the vehicle's driving mode (such as economy mode, sports mode, etc.). For example, the vehicle may be in a high-load, high-speed operating condition in sports mode.

[0098] Optionally, regarding the detection method of the working condition type, in a possible implementation manner, the detection module 73 is specifically used to: Calculate the average fuel consumption per 100 kilometers at the current mileage correction interval; The current operating condition type of the vehicle is determined based on the fuel consumption range of the average fuel consumption per 100 kilometers, and the fuel consumption range corresponds to the operating condition type one by one.

[0099] Specifically, the instantaneous fuel consumption per 100 kilometers at each moment within the current mileage correction interval is obtained. The instantaneous fuel consumption per 100 kilometers refers to the amount of fuel consumed by the vehicle for every 100 kilometers traveled at a certain moment or in a short period of time, usually in liters / 100 kilometers (L / 100km). It is one of the important indicators for measuring the fuel economy of a vehicle and can reflect the fuel consumption of the vehicle under specific driving conditions. For example, the instantaneous fuel consumption per 100 kilometers can be calculated based on the fuel flow and vehicle speed, and the instantaneous fuel consumption per 100 kilometers can also be calculated based on the fuel consumption and driving distance.

[0100] Furthermore, the average value of the instantaneous fuel consumption per 100 kilometers at all times within the current mileage correction interval is calculated to obtain the average fuel consumption per 100 kilometers within the current mileage correction interval. Optionally, when the current mileage correction interval is short, the instantaneous fuel consumption per 100 kilometers can be used as the average fuel consumption per 100 kilometers.

[0101] Furthermore, the current operating condition type of the vehicle is determined based on the fuel consumption range of the average fuel consumption per 100 kilometers, and the fuel consumption range corresponds to the operating condition type one by one.

[0102] For example, multiple fuel consumption ranges can be set from low to high, and each fuel consumption range corresponds to a working condition type. Specifically, after calculating the average fuel consumption per 100 kilometers, the fuel consumption range to which the average fuel consumption per 100 kilometers belongs is determined, and the working condition type corresponding to the fuel consumption range is used as the current working condition type of the vehicle.

[0103] The second determination module 74 is used to determine the mileage correction coefficient at the current mileage correction interval according to the operating condition type.

[0104] The mileage correction factor represents the change in the oil deterioration rate under the corresponding operating condition type (or fuel consumption level). It can be understood that the mileage correction factor is used to adjust the actual mileage to reflect the actual degree of oil deterioration.

[0105] Specifically, from multiple operating condition types, a reference operating condition type is set, and the mileage correction factor corresponding to the reference operating condition type is set to a fixed reference value. The remaining operating condition types are compared with the reference operating condition type to calculate the corresponding mileage correction factor. For example, four fuel consumption ranges are set from low to high, and each fuel consumption range corresponds to a working condition type, that is, four working condition types are set, and the light load working condition is set as the reference working condition type, and the mileage correction factor corresponding to the light load working condition is set to 0. The remaining three working condition types are compared with the reference working condition type to calculate the corresponding mileage correction factor.

[0106] In this embodiment, there is no specific limitation on the calculation method of the mileage correction coefficient corresponding to the other operating condition types. In one example, the mileage correction coefficient is set to a fixed value for each operating condition type. For example, the mileage correction coefficient corresponding to the reference operating condition type is set to 0, and different values ​​are set for the other three operating condition types. In another example, the mileage correction coefficients corresponding to the other operating condition types can be dynamically calculated, and these coefficients can be dynamically adjusted based on the real-time monitored fuel consumption data and a preset calculation formula. For example, a linear or nonlinear function can be used to describe the relationship between fuel consumption and the mileage correction coefficient, and the corresponding mileage correction coefficient can be calculated based on the real-time fuel consumption data.

[0107] The third determination module 75 is used to determine, for each power device in the vehicle power system, an oil replacement cycle coefficient corresponding to the power device according to the type of the vehicle and the model of the power device.

[0108] In this embodiment, the vehicle power system includes a plurality of power devices. For example, the power devices in the vehicle power system include, but are not limited to, an engine, a gearbox, and a drive axle. Accordingly, the models of the power devices include, but are not limited to, an engine model, a gearbox model, and a drive axle model.

[0109] Specifically, the oil replacement cycle coefficient is determined according to the type of vehicle and the model of the power unit. It is understood that the oil replacement cycle coefficient is used to correct the actual mileage to adapt to the characteristics of different vehicles and power system devices.

[0110] In actual applications, the vehicle type and the power unit do not change during the operation of the vehicle. Optionally, the oil replacement cycle coefficient can be determined according to either the vehicle type or the power unit model. Optionally, when the vehicle type and the power system device do not change, the oil replacement cycle coefficient can be set to a fixed value in advance.

[0111] Optionally, in a possible implementation manner, the third determining module 75 is specifically configured to: Based on the type of vehicle and the model of the power unit, the MAP diagram is queried to obtain the oil replacement cycle coefficient corresponding to the power unit; wherein the MAP diagram is a corresponding relationship diagram between different vehicle types and different power unit models and the oil replacement cycle coefficient.

[0112] For example, there are m types of vehicles and n types of power unit models. Create an m times n MAP diagram (Matrix diagram). Based on the reference vehicle type and reference power unit model, the corresponding oil change cycle coefficient is 1. The remaining mn-1 types are compared with the basic value to calculate the corresponding oil change cycle coefficient.

[0113] First, define the MAP diagram. Specifically, establish an m×n matrix, where m represents the number of different vehicle types and n represents the number of different power unit models.

[0114] Further, a reference vehicle type and a reference power unit model are selected, and the combination of the reference vehicle type and the reference power unit model is taken as the basic value, and the corresponding oil change cycle coefficient is set to 1. This means that the oil change cycle of this basic combination does not need any adjustment.

[0115] Furthermore, for the remaining mn-1 combinations of vehicle types and power system device models in the MAP diagram, each needs to be compared with the base value to calculate the corresponding oil change cycle coefficient. For example, the calculation of the oil change cycle coefficient may be based on experimental data, statistical analysis, or expert experience to determine the specific impact of different vehicle types and power system device models on the oil change cycle.

[0116] On this basis, based on the type of vehicle and the model of the power unit, the oil change cycle coefficient corresponding to the power unit can be obtained by querying the MAP diagram.

[0117] The correction module 76 is used to correct the actual mileage based on the mileage correction coefficient at the current mileage correction interval and the oil replacement cycle coefficient corresponding to the power unit, and obtain the corrected mileage corresponding to the power unit at the current mileage correction interval.

[0118] Specifically, in a possible implementation manner, the correction module 76 is specifically used to: The product of the mileage correction coefficient at the current mileage correction interval, the oil replacement cycle coefficient corresponding to the power unit and the actual mileage is calculated to obtain the corrected mileage corresponding to the power unit at the current mileage correction interval.

[0119] Combined with the above description, the mileage correction factor is determined based on the current operating condition type, and the oil change cycle coefficient is determined based on the type of vehicle and the model of the power unit. Based on the mileage correction factor and the oil change cycle coefficient, the actual mileage is double-corrected, and the corrected mileage obtained can more comprehensively evaluate the actual deterioration of the oil. It can be understood that the mileage correction factor ensures the equivalence of mileage under different operating conditions, while the oil change cycle coefficient ensures the adaptability of the oil change cycle. The combined use of these two coefficients improves the accuracy of the oil change reminder, ensuring that the user is reminded to change the oil when it is about to reach the degradation limit.

[0120] It is understandable that based on the mileage correction coefficient and the oil change cycle coefficient corresponding to the power unit, the actual mileage is corrected to obtain the corrected mileage, and the mileage of different working conditions, different vehicles, and different power units can be corrected to a unified evaluation level, so that it is possible to accurately judge whether an oil change reminder is needed based on the corrected mileage. It can be seen that the vehicle power system oil change reminder method of the present application can meet the oil change reminder requirements of different working conditions, different vehicles, and different power units, and improve the accuracy and reliability of the oil change reminder.

[0121] The accumulation module 77 is used to accumulate the total corrected mileage corresponding to the power device after the last driving process and the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process after the current driving process is completed, so as to obtain the total corrected mileage corresponding to the power device after the current driving process is completed.

[0122] In practical applications, after each driving process, the total corrected mileage corresponding to the power device is updated. Specifically, before the vehicle starts the current driving process, the vehicle is powered on and the total corrected mileage corresponding to the power device after the last driving process is read. Furthermore, after the current driving process is completed, the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process is obtained. Furthermore, the total corrected mileage corresponding to the power device after the last driving process is completed and the corrected mileage corresponding to the power device at all mileage correction intervals during the current driving process are accumulated and calculated to obtain the total corrected mileage corresponding to the power device after the current driving process is completed.

[0123] Optionally, during each driving process, the corrected mileage corresponding to the power device at each mileage correction interval is cached, so that after the driving is completed, the corrected mileage corresponding to the power device at all mileage correction intervals during the driving process can be obtained.

[0124] Optionally, in a possible implementation manner, the above device further includes: The storage module is used to store the total corrected mileage corresponding to the power device after the current driving process is completed.

[0125] In this embodiment, after the current driving process is completed, the total corrected mileage corresponding to the power unit is stored so that the total corrected mileage corresponding to the power unit after the last driving process is read after the next power-on, thereby accumulating and updating the total corrected mileage, thereby improving the accuracy and reliability of the oil change reminder.

[0126] The prompt module 78 is used to output oil replacement prompt information to the user if the total corrected mileage corresponding to the power unit after the current driving process ends reaches a preset replacement mileage.

[0127] The preset replacement mileage refers to the oil replacement cycle mileage determined based on factors such as vehicle type, power unit model, oil type, and the maintenance cycle recommended by the manufacturer. The purpose of determining the preset replacement mileage is to ensure that the oil is used in the best condition, extend the service life of the power unit, and maintain the performance of the vehicle.

[0128] For example, the preset replacement mileage of the engine oil of a vehicle is 10,000 kilometers. After the current driving, the total corrected mileage of the engine reaches 10,500 kilometers, and the oil replacement reminder information is output to the user.

[0129] It can be understood that by comparing the total corrected mileage corresponding to the power unit with the preset replacement mileage, if the total corrected mileage reaches or exceeds the preset replacement mileage, the oil change reminder is triggered, which can remind the user to change the oil in time to ensure that the power unit operates in the best condition, thereby extending the service life of the power unit and maintaining vehicle performance.

[0130] Specifically, in a possible implementation manner, when the prompt module 78 is used to output the oil replacement prompt information to the user, it is specifically used to: The oil change reminder information is sent to the instrument panel so that the instrument panel displays the oil change reminder information to the user; wherein the oil change reminder information includes: the total corrected mileage corresponding to the power unit after the end of this driving process, the estimated remaining mileage or estimated remaining time before the next oil change, and the model of the power unit.

[0131] In this embodiment, the oil replacement prompt information is sent to the instrument panel and displayed to the user, and the prompt information includes details such as the total corrected mileage, the estimated remaining mileage or time, the power unit model, etc. The user can intuitively see the total corrected mileage corresponding to the power unit after the current driving process through the instrument panel, and clearly understand the current oil usage and mileage without additional query or calculation, which improves the convenience and intuitiveness of information acquisition.

[0132] Optionally, in a possible implementation manner, the above device further includes: The initialization module is used for initializing the total corrected mileage corresponding to the power unit to zero each time the oil is replaced.

[0133] In this embodiment, after each oil change, the oil usage of the power unit starts over, and initializing the total corrected mileage to zero can ensure that the calculation of the next oil change cycle starts from zero, avoiding cumulative errors and improving the accuracy and reliability of the oil change reminder.

[0134] In the vehicle power system oil replacement reminder device provided in this embodiment, the actual mileage is corrected by comprehensively considering multiple factors such as vehicle speed, working condition type, vehicle type and power unit model to obtain the corrected mileage. The corrected mileage can more accurately reflect the actual use and deterioration degree of the oil. Further, after each driving, the total corrected mileage is updated, and it is determined whether the total corrected mileage reaches the preset replacement mileage. If the preset replacement mileage is reached, the oil replacement reminder information is output to the user, thereby improving the accuracy of the oil replacement reminder. Furthermore, accurate oil replacement reminders ensure that the oil is replaced in time when it approaches the degradation limit, avoiding the increased wear of power system components caused by oil degradation, thereby extending the service life of components such as the engine, gearbox, and drive axle, and improving the stability and safety of the vehicle system. In summary, it can be seen that the solution of this embodiment improves the accuracy of the oil replacement reminder, thereby improving the stability and safety of the vehicle system.
