In addition, the skilled person in the art can combine and combine the different embodiments or examples described in the present specification and the features of the different embodiments or examples, without contradiction.

[0053] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments. The following will be described in detail Figures 1 to 6 The vehicle power system oil change reminding method of the present application is described.

[0054] Figure 1 The vehicle power system oil change reminding method of the present application is described. Figure 1 As shown in the flowchart, the method comprises the following steps 101 to 108.

[0055] In practical applications, the execution subject of the vehicle power system oil replacement reminding method can be a vehicle power system oil replacement reminding device. The vehicle power system oil replacement reminding device can be implemented in various ways, such as through a computer program, for example, application software, etc.; or, for example, a chip, etc. It can also be implemented as a medium that stores a related computer program, such as a U disk, a cloud disk, etc.; or, it can also be implemented through an entity device that integrates or installs a related computer program, such as a server, etc.

[0056] Step 101, according to the current vehicle speed, determine the current driving mileage correction interval time.

[0057] In practical applications, the vehicle speed can be obtained in real time by a vehicle speed sensor or other vehicle-mounted systems, and the driving mileage correction interval time is dynamically determined according to the current vehicle speed.

[0058] In this embodiment, the driving mileage correction interval time is dynamically determined according to the vehicle speed. For example, when the vehicle is driving at high speed, the speed is relatively stable, the fuel consumption changes little, and a longer time interval (such as 15 minutes) can be set to calculate and correct the driving mileage. Conversely, when the vehicle is driving at low speed or in the city, the speed changes frequently, the fuel consumption fluctuates greatly, and a shorter time interval (such as 5 minutes) needs to be set to more accurately calculate and correct the driving mileage.

[0059] It can be understood that by reasonably setting and dynamically adjusting the driving mileage correction interval time, the oil replacement reminding system can provide accurate and timely reminders under various driving conditions, helping users better maintain the vehicle power system, prolong its service life and maintain good performance.

[0060] Optionally, the vehicle speed is one of the main bases for determining the driving mileage correction interval time. In addition, the current driving mileage correction interval time can also be determined according to the operating state parameters of the vehicle, such as acceleration, deceleration, climbing, congestion, etc.

[0061] Step 102, calculate the actual driving mileage of the vehicle in the current driving mileage correction interval time.

[0062] The actual driving mileage refers to the total distance actually driven by the vehicle in the current driving mileage correction interval time, usually in kilometers or miles. In practical applications, the actual driving mileage calculated will be used for subsequent mileage correction calculation. The actual driving mileage is corrected in combination with the mileage correction coefficient and the oil replacement period coefficient to obtain a more accurate corrected driving mileage.

[0063] Specifically, the actual driving distance under the current driving distance correction interval time can be calculated by correcting the interval time according to the current speed of the vehicle and the current driving distance correction interval time. For example, the actual driving distance can be obtained by calculating the product of the current speed of the vehicle and the current driving distance correction interval time.

[0064] Step 103, detecting the working condition type under the current driving distance correction interval time.

[0065] As an example, the working condition types involved in the present application include but are not limited to: light load working condition, heavy load working condition, high speed working condition, low speed working condition, and harsh working condition. The light load working condition refers to the light load of the vehicle and the smooth driving. The heavy load working condition refers to the heavy load of the vehicle and the possible need for greater power output. The high speed working condition refers to the driving of the vehicle at a high speed, for example, on a highway. The low speed working condition refers to the driving of the vehicle at a low speed, which can be on urban roads or congested sections. The harsh working condition refers to the conditions unfavorable to the operation of the vehicle, such as extreme weather and complex road conditions.

[0066] Specifically, the detection of the working condition type is not specifically limited in the present application. In one example, a working condition detection device is provided on the vehicle, which comprehensively evaluates the working condition type under the current driving distance correction interval time in combination with the data such as the vehicle speed, the engine speed, the fuel consumption, and the ambient temperature. In another example, the working condition detection device obtains GPS and navigation data, and analyzes the driving route of the vehicle based on the GPS and navigation data, so as to detect the working condition type under the current driving distance correction interval time. In yet another example, the working condition type of the vehicle can be inferred according to the driving mode of the vehicle (such as the economy mode, the sports mode, etc.). For example, the vehicle in the sports mode can be in a high load and high speed working condition.

[0067] Optionally, for the detection method of the working condition type, in one possible implementation, the above step 103 includes:

[0068] calculating the average fuel consumption per 100 kilometers under the current driving distance correction interval time;

[0069] determining the current working condition type of the vehicle according to the fuel consumption range in which the average fuel consumption per 100 kilometers is located, the fuel consumption range corresponding to the working condition type one by one.

[0070] Specifically, the instantaneous fuel consumption at each time point in the current driving mileage correction interval is obtained. The instantaneous fuel consumption refers to the fuel consumption of the vehicle per 100 kilometers in a certain time or a short time, usually in units of liters per 100 kilometers (L / 100km). It is one of the important indicators for measuring the fuel economy of the vehicle, and can reflect the fuel consumption of the vehicle under certain driving conditions. For example, the instantaneous fuel consumption can be calculated based on fuel flow and vehicle speed, and the instantaneous fuel consumption can also be calculated based on fuel consumption and driving distance.

[0071] Further, the average value of the instantaneous fuel consumption at all time points in the current driving mileage correction interval is calculated to obtain the average fuel consumption per 100 kilometers in the current driving mileage correction interval. Alternatively, when the current driving mileage correction interval is small, the instantaneous fuel consumption can be used as the average fuel consumption per 100 kilometers.

[0072] Further, according to the fuel consumption range in which the average fuel consumption per 100 kilometers is located, the current working condition type of the vehicle is determined, and the fuel consumption range and the working condition type are one-to-one corresponding.

[0073] For example, a plurality of fuel consumption ranges can be set from low to high, and each fuel consumption range corresponds to a working condition type. Specifically, after the average fuel consumption per 100 kilometers is calculated, 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 determined as the current working condition type of the vehicle.

[0074] Step 104, determining the mileage correction coefficient in the current driving mileage correction interval according to the working condition type.

[0075] The mileage correction coefficient represents the change of the oil deterioration rate under the corresponding working condition type (or fuel consumption level). It can be understood that the mileage correction coefficient is used to adjust the actual driving mileage to reflect the actual degree of oil deterioration.

[0076] Specifically, a reference working condition type is set from a plurality of working condition types, and the mileage correction coefficient corresponding to the reference working condition type is set as a fixed reference value. The mileage correction coefficients corresponding to the remaining working condition types are calculated compared with the reference working condition type. For example, four fuel consumption ranges are set from low to high, and each fuel consumption range corresponds to a working condition type, i.e. four working condition types are set, and the light load working condition is set as the reference working condition type, and the mileage correction coefficient corresponding to the light load working condition is set as 0. The mileage correction coefficients corresponding to the remaining three working condition types are calculated compared with the reference working condition type.

[0077] In this embodiment, the calculation method of the mileage correction coefficient corresponding to the remaining working condition types is not specifically limited. In one example, the mileage correction coefficient is set to a fixed value for each working condition type, for example, the mileage correction coefficient corresponding to the reference working condition type is set to 0, and different values are set for the remaining three working condition types. In another example, the mileage correction coefficients corresponding to the remaining working condition types can be dynamically calculated, and these coefficients can be dynamically adjusted according to the real-time monitored fuel consumption data and the preset calculation formula. For example, a linear or nonlinear function can be used to describe the relationship between fuel consumption and mileage correction coefficient, and the corresponding mileage correction coefficient is calculated according to the real-time fuel consumption data.

[0078] In step 105, for each power device in the vehicle power system, a oil replacement period coefficient corresponding to the power device is determined according to the type of the vehicle and the model of the power device.

[0079] 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: engine, gearbox, drive axle. Correspondingly, the model of the power device includes but is not limited to: engine model, gearbox model, drive axle model.

[0080] Specifically, the oil replacement period coefficient is determined according to the type of the vehicle and the model of the power device. It can be understood that the oil replacement period coefficient is used to correct the actual mileage to adapt to the characteristics of different vehicles and power system devices.

[0081] In practical application, the type of the vehicle and the power device do not change during the operation of the vehicle. Alternatively, the oil replacement period coefficient can be determined according to any one of the type of the vehicle or the model of the power device. Alternatively, the oil replacement period coefficient can be set to a fixed value in advance under the condition that the type of the vehicle and the power system device do not change.

[0082] Alternatively, in one possible implementation, the above step 105 specifically includes:

[0083] According to the type of the vehicle and the model of the power device, a MAP chart is queried to obtain the oil replacement period coefficient corresponding to the power device; wherein, the MAP chart is a corresponding relationship chart of different vehicle types and different power device models and oil replacement period coefficients.

[0084] For example, the vehicle type is divided into m types, and the power device model is divided into n types. An m by n MAP chart (Matrix chart) is established. Based on the reference vehicle type and the reference power device model, the corresponding oil replacement period coefficient is 1, and the remaining mn-1 types are compared with the base value to calculate the corresponding oil replacement period coefficient.

[0085] First, a MAP chart is defined, specifically, an m x n matrix is established, where m represents the number of different vehicle types, and n represents the number of different power device models.

[0086] Further, a reference vehicle type and a reference power device model are selected, and the combination of the reference vehicle type and the reference power device model is taken as the base value, and the corresponding oil change period coefficient is set to 1. This means that the oil change period of this base combination does not need any adjustment.

[0087] Further, for the remaining mn-1 combinations of vehicle types and power system device models in the MAP chart, each needs to be compared with the base value to calculate the corresponding oil change period coefficient. For example, the calculation of the oil change period coefficient can be based on experimental data, statistical analysis or expert experience to determine the specific influence of different vehicle types and power device models on the oil change period.

[0088] On this basis, based on the type of vehicle and the model of the power device, the MAP chart is queried to obtain the oil change period coefficient corresponding to the power device.

[0089] Step 106, based on the mileage correction coefficient under the current driving mileage correction interval time and the oil change period coefficient corresponding to the power device, correct the actual driving mileage to obtain the corrected driving mileage corresponding to the power device under the current driving mileage correction interval time.

[0090] Specifically, in one possible implementation, the above step 106 specifically includes:

[0091] Calculating the product of the mileage correction coefficient under the current driving mileage correction interval time, the oil change period coefficient corresponding to the power device, and the actual driving mileage to obtain the corrected driving mileage corresponding to the power device under the current driving mileage correction interval time.

[0092] In combination with the above description, the mileage correction coefficient is determined according to the current working condition type, and the oil change period coefficient is determined based on the type of vehicle and the model of the power device. Based on the mileage correction coefficient and the oil change period coefficient, the actual driving mileage is corrected twice to obtain the corrected driving mileage, which can more comprehensively evaluate the actual deterioration of the oil. It can be understood that the mileage correction coefficient ensures the equivalence of driving mileage under different working conditions, and the oil change period coefficient ensures the adaptability of the oil change period. The use of these two coefficients improves the accuracy of the oil change reminder and ensures that the user is reminded to change the oil when it is about to reach the deterioration limit.

[0093] It can be understood that the actual driving mileage is corrected based on the mileage correction coefficient and the oil replacement period coefficient corresponding to the power device to obtain the corrected driving mileage, the driving mileage of different working condition types, different vehicles and different power devices can be corrected to a unified evaluation level, so that it can be judged whether the oil replacement reminder is needed according to the corrected driving mileage. Therefore, the vehicle power system oil replacement reminding method can meet the oil replacement reminding needs of different working condition types, different vehicles and different power devices, and improve the accuracy and reliability of the oil replacement reminding.

[0094] In step 107, after the current driving is completed, the total corrected driving mileage corresponding to the power device after the last driving process is completed is accumulated with the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process to obtain the total corrected driving mileage corresponding to the power device after the current driving process is completed.

[0095] In actual application, the total corrected driving mileage corresponding to the power device is updated after each driving is completed. Specifically, before the vehicle starts the current driving, the vehicle is powered on, and the total corrected driving mileage corresponding to the power device after the last driving process is completed is read. Further, after the current driving is completed, the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process is obtained. Further, the total corrected driving mileage corresponding to the power device after the last driving process is completed is accumulated with the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process to obtain the total corrected driving mileage corresponding to the power device after the current driving process is completed.

[0096] Optionally, in each driving process, the corrected driving mileage corresponding to the power device at each driving mileage correction interval time is cached, so that the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the driving process is obtained after the driving is completed.

[0097] Optionally, in a possible implementation, after step 107, the method further includes:

[0098] The total corrected driving mileage corresponding to the power device after the current driving process is completed is stored.

[0099] In the embodiment, the total corrected driving mileage corresponding to the power device after the current driving process is completed is stored, so that the total corrected driving mileage corresponding to the power device after the last driving process is completed is read after the next power-on, and the total corrected driving mileage is accumulated and updated, thereby improving the accuracy and reliability of the oil replacement reminding.

[0100] Step 108: If the total modified driving mileage corresponding to the power device after the current driving process ends reaches the preset replacement mileage, output oil replacement prompt information to the user.

[0101] The preset replacement mileage refers to the oil replacement period mileage determined according to factors such as vehicle type, power device model, oil type, and manufacturer-recommended maintenance period. The purpose of determining the preset replacement mileage is to ensure that the oil is used in the best state, prolong the service life of the power device, and maintain the performance of the vehicle.

[0102] For example, the preset replacement mileage of the engine oil of a certain vehicle is 10,000 kilometers. After the current driving ends, the total modified driving mileage of the engine reaches 10,500 kilometers, and the oil replacement prompt information is output to the user.

[0103] It can be understood that by comparing the total modified driving mileage corresponding to the power device with the preset replacement mileage, if the total modified driving mileage reaches or exceeds the preset replacement mileage, the oil replacement prompt is triggered, which can timely remind the user to replace the oil, so as to ensure that the power device operates in the best state, thereby prolonging the service life of the power device and maintaining the performance of the vehicle.

[0104] Specifically, in one possible implementation, the step 108 of outputting the oil replacement prompt information to the user specifically includes:

[0105] The oil replacement prompt information is sent to the instrument panel, so that the instrument panel displays the oil replacement prompt information to the user; wherein the oil replacement prompt information includes the total modified driving mileage corresponding to the power device after the current driving process ends, the estimated remaining mileage or estimated remaining time to the next oil replacement, and the model of the power device.

[0106] In this embodiment, the oil replacement prompt information is sent to the instrument panel and displayed to the user, and the prompt information includes detailed content such as the total modified driving mileage, the estimated remaining mileage or time, and the model of the power device. The user can intuitively see the total modified driving mileage corresponding to the power device after the current driving process ends through the instrument panel, clearly understand the current use of the oil and the driving mileage, without the need for additional inquiry or calculation, thereby improving the convenience and intuitiveness of information acquisition.

[0107] Optionally, in one possible implementation, the method further includes:

[0108] At each oil replacement, the total modified driving mileage corresponding to the power device is initialized to zero.

[0109] In this embodiment, after each oil replacement, the oil usage of the power device is restarted, and initializing the total modified driving mileage to zero can ensure that the calculation of the next oil replacement period starts from zero, avoid accumulated errors, and improve the accuracy and reliability of the oil replacement reminder.

[0110] In order to better understand the vehicle power system oil replacement reminding method of the present application, the following will be described in conjunction with specific examples.

[0111] Specifically, in the semi-load working condition, the vehicle test is carried out when the vehicle speed changes between 50km / h and 80km / h, to verify the effectiveness of the vehicle power system oil replacement reminding 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 is a schematic diagram of the change of driving mileage provided by the present application. Figure 3 is a schematic diagram of the change of oil consumption provided by the present application. Figure 4 is a total mileage correction effect diagram of the engine oil replacement reminding system provided by the present application. Figure 5 is a total mileage correction effect diagram of the gearbox oil replacement reminding system provided by the present application. Figure 6 is a total mileage correction effect diagram of the drive axle oil replacement reminding system provided by the present application.

[0112] In the vehicle power system oil replacement reminding method provided by the present embodiment, the actual driving mileage is modified by comprehensively considering multiple factors such as vehicle speed, working condition type, vehicle type and power device model, to obtain the modified driving mileage, which can more accurately reflect the actual usage and degradation of the oil. Further, after each driving is completed, the total modified driving mileage is updated, and it is judged whether the total modified driving mileage reaches the preset replacement mileage. If the total modified driving mileage reaches the preset replacement mileage, the oil replacement prompt information is output to the user, which improves the accuracy of the oil replacement reminder. Further, the accurate oil replacement reminder ensures that the oil is replaced in time when it is close to the degradation limit, avoids the aggravation of the wear of the power system components caused by the degradation of the oil, thereby prolongs the service life of the engine, gearbox, drive axle and other components, and improves the stability and safety of the vehicle system. In summary, the scheme of the present embodiment improves the accuracy of the oil replacement reminder, and further improves the stability and safety of the vehicle system.

[0113] The vehicle power system oil replacement reminding device provided by the present application will be described below. The vehicle power system oil replacement reminding device described below can be referred to in conjunction with the vehicle power system oil replacement reminding method described above.

[0114] In practical applications, the vehicle power system oil replacement reminding device can be implemented in various ways, such as through a computer program, for example, application software, etc.; or, for example, a chip, etc. It can also be implemented as a medium that stores a related computer program, such as a U disk, a cloud disk, etc.; or, it can also be implemented through an entity device that integrates or installs a related computer program, such as a server, etc.

[0115] Figure 7 is a structural schematic diagram of the vehicle power system oil replacement reminding device provided by the present application, as Figure 7 shown, the vehicle power system oil replacement reminding device comprises 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 prompting module 78.

[0116] The first determination module 71 is configured to determine the current driving distance correction interval time according to the current vehicle speed.

[0117] In practical applications, the vehicle speed can be obtained in real time through a vehicle speed sensor or other vehicle-mounted systems, and the driving distance correction interval time is dynamically determined according to the current vehicle speed.

[0118] Among them, the driving distance correction interval time refers to the time period for calculating and correcting the driving distance during the driving of the vehicle. In this embodiment, the driving distance correction interval time is dynamically determined according to the vehicle speed. For example, when the vehicle is driving at high speed, the vehicle speed is relatively stable, the fuel consumption changes little, and a longer time interval (such as 15 minutes) can be set to calculate and correct the driving distance. In contrast, when the vehicle is driving at low speed or in the city, the vehicle speed changes frequently, the fuel consumption fluctuates greatly, and a shorter time interval (such as 5 minutes) needs to be set to more accurately calculate and correct the driving distance.

[0119] It can be understood that by reasonably setting and dynamically adjusting the driving distance correction interval time, the oil replacement reminding system can provide accurate and timely reminders under various driving conditions, helping users to better maintain the vehicle power system, prolong its service life and maintain good performance.

[0120] Optionally, the vehicle speed is one of the main bases for determining the driving distance correction interval time, in addition to which, the current driving distance correction interval time can also be determined according to the operating state parameters of the vehicle, such as acceleration, deceleration, climbing, congestion, etc.

[0121] The above calculation module 72 is configured to calculate the actual driving distance of the vehicle in the current driving distance correction interval time.

[0122] The actual mileage refers to the total distance actually traveled by the vehicle in 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 in combination with the mileage correction coefficient and the oil replacement period coefficient to obtain a more accurate corrected mileage.

[0123] Specifically, the actual mileage in the current mileage correction interval can be calculated according to 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.

[0124] The detection module 73 is configured to detect the working condition type in the current mileage correction interval.

[0125] For example, the working condition types disclosed in the present application include but are not limited to light load working condition, heavy load working condition, high speed working condition, low speed working condition, and harsh working condition. The light load working condition refers to a condition in which the vehicle is lightly loaded and travels smoothly. The heavy load working condition refers to a condition in which the vehicle is heavily loaded and may require greater power output. The high speed working condition refers to a condition in which the vehicle travels at a high speed, for example, on a highway. The low speed working condition refers to a condition in which the vehicle travels at a low speed, for example, on urban roads or congested sections. The harsh working condition refers to a condition in which the vehicle is adversely affected by, for example, extreme weather or complex road conditions.

[0126] Specifically, the detection of the working condition type is not specifically limited in the present application. In one example, a working condition detection device is provided on the vehicle, which comprehensively evaluates the working condition type in the current mileage correction interval based on data such as vehicle speed, engine speed, fuel consumption, and ambient temperature. In another example, the working condition detection device obtains GPS and navigation data, and analyzes the driving route of the vehicle based on the GPS and navigation data to detect the working condition type in the current mileage correction interval. In yet another example, the working condition type of the vehicle can be inferred according to the driving mode of the vehicle (e.g., economy mode, sports mode, etc.). For example, the vehicle in sports mode may be in a high load and high speed working condition.

[0127] Optionally, for the detection method of the working condition type, in one possible implementation, the detection module 73 is specifically configured to:

[0128] calculate the average fuel consumption per 100 kilometers in the current mileage correction interval;

[0129] determine the current working condition type of the vehicle according to the fuel consumption range in which the average fuel consumption per 100 kilometers falls, wherein the fuel consumption range and the working condition type are in one-to-one correspondence.

[0130] Specifically, the instantaneous fuel consumption at each time point in the current driving mileage correction interval is obtained. The instantaneous fuel consumption refers to the fuel consumption of the vehicle per 100 kilometers in a certain time or a short time, usually in units of liters per 100 kilometers (L / 100km). It is one of the important indicators for measuring the fuel economy of the vehicle, and can reflect the fuel consumption of the vehicle under certain driving conditions. For example, the instantaneous fuel consumption can be calculated based on fuel flow and vehicle speed, and the instantaneous fuel consumption can also be calculated based on fuel consumption and driving distance.

[0131] Further, the average value of the instantaneous fuel consumption at all time points in the current driving mileage correction interval is calculated to obtain the average fuel consumption per 100 kilometers in the current driving mileage correction interval. Alternatively, when the current driving mileage correction interval is small, the instantaneous fuel consumption can be used as the average fuel consumption per 100 kilometers.

[0132] Further, according to the fuel consumption range in which the average fuel consumption per 100 kilometers is located, the current working condition type of the vehicle is determined, and the fuel consumption range and the working condition type are one-to-one corresponding.

[0133] For example, a plurality of fuel consumption ranges can be set from low to high, and each fuel consumption range corresponds to a working condition type. Specifically, after the average fuel consumption per 100 kilometers is calculated, 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 determined as the current working condition type of the vehicle.

[0134] The second determination module 74 is configured to determine the mileage correction coefficient in the current driving mileage correction interval according to the working condition type.

[0135] The mileage correction coefficient represents the change of the oil deterioration rate under the corresponding working condition type (or fuel consumption level). It can be understood that the mileage correction coefficient is used to adjust the actual driving mileage to reflect the actual degree of oil deterioration.

[0136] Specifically, a reference working condition type is set from a plurality of working condition types, and the mileage correction coefficient corresponding to the reference working condition type is set as a fixed reference value. The mileage correction coefficients corresponding to the other working condition types are calculated compared with the reference working condition type. For example, four fuel consumption ranges are set from low to high, and each fuel consumption range corresponds to a working condition type, i.e. four working condition types are set, and the light load working condition is set as the reference working condition type, and the mileage correction coefficient corresponding to the light load working condition is set as 0. The mileage correction coefficients corresponding to the other three working condition types are calculated compared with the reference working condition type.

[0137] In this embodiment, the calculation method of the mileage correction coefficient corresponding to the remaining working condition types is not specifically limited. In one example, the mileage correction coefficient is set to a fixed value for each working condition type, for example, the mileage correction coefficient corresponding to the reference working condition type is set to 0, and different values are set for the remaining three working condition types. In another example, the mileage correction coefficients corresponding to the remaining working condition types can be dynamically calculated, and these coefficients can be dynamically adjusted according to the real-time monitored fuel consumption data and the preset calculation formula. For example, a linear or nonlinear function can be used to describe the relationship between fuel consumption and mileage correction coefficient, and the corresponding mileage correction coefficient is calculated according to the real-time fuel consumption data.

[0138] The third determination module 75 is configured to determine, for each power device in the vehicle power system, an oil replacement period coefficient corresponding to the power device according to the type of the vehicle and the model of the power device.

[0139] 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. Correspondingly, the model of the power device includes but is not limited to an engine model, a gearbox model, and a drive axle model.

[0140] Specifically, the oil replacement period coefficient is determined according to the type of the vehicle and the model of the power device. It can be understood that the oil replacement period coefficient is used to correct the actual mileage to adapt to the characteristics of different vehicles and power system devices.

[0141] In actual application, the type of the vehicle and the power device do not change during the operation of the vehicle. Alternatively, the oil replacement period coefficient can be determined according to any one of the type of the vehicle or the model of the power device. Alternatively, the oil replacement period coefficient can be set to a fixed value in advance under the condition that the type of the vehicle and the power system device do not change.

[0142] Alternatively, in one possible implementation, the third determination module 75 is specifically configured to:

[0143] query a MAP diagram to obtain the oil replacement period coefficient corresponding to the power device based on the type of the vehicle and the model of the power device; wherein the MAP diagram is a corresponding relationship diagram of different vehicle types and different power device models and the oil replacement period coefficient.

[0144] For example, the vehicle type is divided into m types, and the power device model is divided into n types. An m by n MAP diagram (Matrix diagram) is established. Based on the reference vehicle type and the reference power device model, the corresponding oil replacement period coefficient is 1, and the remaining mn-1 types are compared with the base value to calculate the corresponding oil replacement period coefficient.

[0145] First, a MAP chart is defined, specifically, an m x n matrix is established, where m represents the number of different vehicle types, and n represents the number of different power device models.

[0146] Further, a reference vehicle type and a reference power device model are selected, and the combination of the reference vehicle type and the reference power device model is taken as the base value, and the corresponding oil change period coefficient is set to 1. This means that the oil change period of this base combination does not need any adjustment.

[0147] Further, for the remaining mn-1 combinations of vehicle types and power system device models in the MAP chart, each needs to be compared with the base value to calculate the corresponding oil change period coefficient. For example, the calculation of the oil change period coefficient can be based on experimental data, statistical analysis or expert experience to determine the specific influence of different vehicle types and power device models on the oil change period.

[0148] On this basis, based on the type of vehicle and the model of the power device, the MAP chart is queried, and the oil change period coefficient corresponding to the power device can be obtained.

[0149] The above-mentioned correction module 76 is used to correct the actual driving mileage based on the mileage correction coefficient at the current driving mileage correction interval and the oil change period coefficient corresponding to the power device, and obtain the corrected driving mileage corresponding to the power device at the current driving mileage correction interval.

[0150] Specifically, in one possible implementation, the above-mentioned correction module 76 is specifically used to:

[0151] Calculate the product of the mileage correction coefficient at the current driving mileage correction interval, the oil change period coefficient corresponding to the power device, and the actual driving mileage, to obtain the corrected driving mileage corresponding to the power device at the current driving mileage correction interval.

[0152] In combination with the above description, the mileage correction coefficient is determined according to the current working condition type, and the oil change period coefficient is determined based on the type of vehicle and the model of the power device. Based on the mileage correction coefficient and the oil change period coefficient, the actual driving mileage is double corrected to obtain the corrected driving mileage, which can more comprehensively evaluate the actual deterioration of the oil. It can be understood that the mileage correction coefficient ensures the equivalence of the driving mileage under different working conditions, and the oil change period coefficient ensures the adaptability of the oil change period. The use of these two coefficients improves the accuracy of the oil change reminder and ensures that the user is reminded to change the oil when it is about to reach the deterioration limit.

[0153] It can be understood that the actual driving mileage is corrected based on the mileage correction coefficient and the oil replacement period coefficient corresponding to the power device to obtain the corrected driving mileage, the driving mileage of different working condition types, different vehicles and different power devices can be corrected to a unified evaluation level, so that it can be judged whether the oil replacement reminder is needed according to the corrected driving mileage. Therefore, the vehicle power system oil replacement reminding method can meet the oil replacement reminding needs of different working condition types, different vehicles and different power devices, and improve the accuracy and reliability of the oil replacement reminding.

[0154] The accumulation module 77 is configured to accumulate the total corrected driving mileage corresponding to the power device after the last driving process and the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process to obtain the total corrected driving mileage corresponding to the power device after the current driving process.

[0155] In actual application, the total corrected driving mileage corresponding to the power device is updated after each driving. Specifically, before the current driving of the vehicle starts, the vehicle is powered on, and the total corrected driving mileage corresponding to the power device after the last driving process is read. Further, after the current driving ends, the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process is obtained. Further, the total corrected driving mileage corresponding to the power device after the last driving process and the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the current driving process are accumulated to obtain the total corrected driving mileage corresponding to the power device after the current driving process.

[0156] Optionally, in each driving process, the corrected driving mileage corresponding to the power device at each driving mileage correction interval time is cached, so that the corrected driving mileage corresponding to the power device at all driving mileage correction interval times in the driving process is obtained after the driving ends.

[0157] Optionally, in a possible implementation, the device further includes:

[0158] The storage module is configured to store the total corrected driving mileage corresponding to the power device after the current driving process.

[0159] In the embodiment, the total corrected driving mileage corresponding to the power device is stored after the current driving process, so that the total corrected driving mileage corresponding to the power device after the last driving process is read after the next power-on, and the total corrected driving mileage is accumulated and updated, thereby improving the accuracy and reliability of the oil replacement reminding.

[0160] The prompt module 78 is configured to output the oil replacement prompt information to the user if the total corrected driving mileage corresponding to the power device after the current driving process ends reaches the preset replacement mileage.

[0161] The preset replacement mileage refers to a replacement mileage of the oil determined according to factors such as a vehicle type, a power device model, an oil type, and a manufacturer-recommended maintenance period. The purpose of determining the preset replacement mileage is to ensure that the oil is used in an optimal state, prolong the service life of the power device, and maintain the performance of the vehicle.

[0162] For example, the preset replacement mileage of the engine oil of a vehicle is 10,000 kilometers. After the current driving process ends, the total corrected driving mileage of the engine reaches 10,500 kilometers. Then, the oil replacement prompt information is output to the user.

[0163] It can be understood that by comparing the total corrected driving mileage corresponding to the power device with the preset replacement mileage, if the total corrected driving mileage reaches or exceeds the preset replacement mileage, the oil replacement prompt is triggered, which can timely remind the user to replace the oil, so as to ensure that the power device operates in an optimal state, thereby prolonging the service life of the power device and maintaining the performance of the vehicle.

[0164] Specifically, in a possible implementation, when the prompt module 78 is used to output the oil replacement prompt information to the user, the prompt module 78 is specifically configured to:

[0165] send the oil replacement prompt information to an instrument panel, so that the instrument panel displays the oil replacement prompt information to the user; wherein the oil replacement prompt information includes the total corrected driving mileage corresponding to the power device after the current driving process ends, the predicted remaining mileage or predicted remaining time to the next oil replacement, and the model of the power device.

[0166] In this embodiment, the oil replacement prompt information is sent to the instrument panel and displayed to the user, and the prompt information includes detailed content such as the total corrected driving mileage, the predicted remaining mileage or time, and the model of the power device. The user can intuitively see the total corrected driving mileage corresponding to the power device after the current driving process ends through the instrument panel, and clearly understand the use of the current oil and the driving mileage, without the need for additional inquiry or calculation, thereby improving the convenience and intuitiveness of information acquisition.

[0167] Optionally, in a possible implementation, the device further includes:

[0168] An initialization module configured to initialize the total corrected driving mileage corresponding to the power device to zero each time the oil is replaced.

[0169] In this embodiment, after each oil replacement, the oil usage of the power device is restarted, and initializing the total modified driving mileage to zero can ensure that the calculation of the next oil replacement period starts from zero, avoid accumulated errors, and improve the accuracy and reliability of the oil replacement reminder.

[0170] The vehicle power system oil replacement reminder device provided in this embodiment can modify the actual driving mileage by comprehensively considering multiple factors such as vehicle speed, working condition type, vehicle type, and power device model, obtain modified driving mileage, and more accurately reflect the actual usage and degradation of the oil. Further, after each driving is completed, the total modified driving mileage is updated, and it is determined whether the total modified driving mileage reaches the preset replacement mileage. If the total modified driving mileage reaches the preset replacement mileage, the oil replacement prompt information is output to the user, and the accuracy of the oil replacement reminder is improved. Further, the accurate oil replacement reminder ensures that the oil is replaced in time when it is close to the degradation limit, avoids the aggravation of the wear of the power system components caused by the degradation of the oil, thereby prolongs the service life of the engine, the transmission, the drive axle, and other components, and improves the stability and safety of the vehicle system. In summary, the scheme of this embodiment improves the accuracy of the oil replacement reminder, and further improves the stability and safety of the vehicle system.
