[0002] Hybrid vehicles are equipped with hybrid engines, which consist of an internal combustion engine and an electric motor. In actual use, the internal combustion engine and electric motor work together, resulting in the internal combustion engine's service life being shorter than that of the engine in a purely fuel-powered vehicle. For hybrid engines, the oil maintenance interval is determined by the time the vehicle's mileage exceeds a certain fixed mileage. However, this method is not very accurate in determining whether the oil needs to be changed, resulting in overly frequent oil changes.

It can be seen that the embodiment of the present application monitors the operating conditions of the hybrid engine of a hybrid vehicle in a low-temperature environment. If the hybrid engine does not have a driving state that meets the preset operating conditions for a long time, it is considered that the water content in the engine oil may be high.

DETAILED DESCRIPTION

[0034] The embodiments of the present application provide a hybrid vehicle monitoring method to solve the technical problem in the prior art of low accuracy in measuring whether the engine oil needs to be replaced based on a fixed mileage.

[0035] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows: In response to each oil change completion signal from the hybrid engine of a hybrid vehicle, the present embodiment monitors the actual accumulated sub-mileage of the hybrid engine at various operating power levels; determines the equivalent oil degradation sub-coefficient corresponding to each operating power level based on the preset oil change mileage and the actual accumulated sub-mileage; determines the actual oil degradation coefficient of the hybrid engine based on the equivalent oil degradation sub-coefficient corresponding to each operating power level; and outputs an oil change reminder signal if the actual oil degradation coefficient is greater than or equal to the preset oil change coefficient. Thus, the present embodiment quantifies the contribution of the actual accumulated sub-mileage corresponding to each operating power level to oil degradation, accumulates the degree of oil degradation of the hybrid engine at each operating power level, and determines whether an oil change is necessary based on the actual operating conditions of the hybrid engine. This improves the accuracy of the hybrid engine's oil change reminder, effectively extending the oil change cycle, increasing oil utilization, reducing oil waste, and lowering oil replacement costs.

[0036] In an embodiment of the present application, in response to a start-up command of the hybrid vehicle, an actual ambient temperature of the environment in which the hybrid vehicle is located is obtained; when the actual ambient temperature is less than a preset ambient temperature, historical operating data of the hybrid engine within a first historical period is obtained; the end time of the first historical period is the time when the hybrid vehicle responds to the start-up command; it is determined whether the historical operating data meets a preset operating condition, where the preset operating condition refers to an actual speed of the hybrid engine exceeding a preset speed and lasting for a time period greater than or equal to a first preset time period, or the preset operating condition refers to an actual water temperature of the hybrid engine exceeding a preset water temperature and lasting for a time period greater than or equal to a second preset time period; and when the historical operating data does not meet the preset operating condition, a reminder signal is output to force the hybrid engine to operate. It can be seen that the embodiment of the present application monitors the operating conditions of the hybrid engine of a hybrid vehicle in a low-temperature environment. If the hybrid engine does not have a driving state that meets the preset operating conditions for a long time, it is considered that the water content in the engine oil may be high. Therefore, the hybrid engine can be forced to operate at a higher load during the user's driving process to reduce the water content in the engine oil, extend the service life of the engine oil, and reduce the degree of corrosion caused by the water in the engine oil to the engine.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] First, the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0039] A hybrid vehicle is a vehicle that uses two or more power sources, typically a traditional internal combustion engine and an electric motor, to work together to improve fuel efficiency, reduce emissions, or enhance performance. A hybrid vehicle is equipped with a hybrid engine, a traditional internal combustion engine (gasoline or diesel) specifically optimized for hybrid powertrains. This engine works in tandem with an electric motor to achieve efficient power output.

[0040] Hybrid engines are similar to traditional internal combustion engines and require lubrication with engine oil. An important factor affecting the oil change cycle is the proportion of the engine operating under high load. If the engine is under high load for a long time, the oil performance deteriorates significantly, and the oil change cycle may be shorter, which means the corresponding maintenance mileage is shortened. For hybrid engines, since the internal combustion engine and the electric motor work together to drive the vehicle, the internal combustion engine in the hybrid engine is used for less time than the engine of a traditional pure fuel vehicle, and the load under high load operation is also less, so the corresponding oil maintenance cycle should be extended.

[0041] However, related technologies still use a fixed maintenance mileage method to determine whether the hybrid engine's oil needs to be replaced. This method causes the hybrid engine's oil to be replaced prematurely before its actual performance reaches the level where it needs to be replaced, resulting in relatively frequent oil replacement cycles. On the one hand, this reduces oil waste, but on the other hand, it also increases the cost of oil replacement.

[0042] In order to solve this problem, the present invention provides a hybrid vehicle monitoring method, which includes steps S11 to S14. Figure 1 .

[0043] Step S11 , in response to an oil change completion signal of a hybrid engine of a hybrid vehicle, monitoring actual accumulated sub-mileage corresponding to each operating power of the hybrid engine; Step S12, determining the equivalent oil degradation sub-coefficient corresponding to each operating power according to the preset oil change mileage corresponding to each operating power and the actual accumulated sub-mileage; Step S13, determining the actual oil degradation coefficient of the hybrid engine according to the equivalent oil degradation sub-coefficients corresponding to the respective operating powers; Step S14: outputting an oil change reminder signal when the actual oil degradation coefficient is greater than or equal to a preset oil change coefficient.

[0044] The present invention provides a hybrid vehicle monitoring method, primarily for monitoring the oil maintenance interval of a hybrid vehicle's hybrid engine. The method can be executed by a controller of the hybrid vehicle or by a remote device associated with the hybrid vehicle (e.g., a cloud server). The present invention uses the hybrid vehicle controller as an example for subsequent description.

[0045] Regarding step S11 , in response to an oil change completion signal of a hybrid engine of a hybrid vehicle, actual accumulated sub-mileages corresponding to respective operating powers of the hybrid engine are monitored.

[0046] When the hybrid engine completes an oil change, it outputs a corresponding oil change completion signal to mark the oil change mileage point. Each time the controller receives an oil change completion signal, it indicates that an oil change has occurred. Based on this, the controller executes steps S11 through S14 until the next oil change completion signal is received, at which point steps S11 through S14 are repeated, repeating this cycle to monitor whether the hybrid vehicle's hybrid engine has undergone an oil change.

[0047] Each time an oil change completion signal is received, the actual accumulated sub-mileage corresponding to each different operating power of the hybrid engine of the hybrid vehicle is monitored from the moment the oil change completion signal is received until the next time the oil change completion signal is received.

[0048] In the embodiments of the present application, the operating power can be divided into different intervals based on the maximum and minimum power values ​​of the internal combustion engine of the hybrid engine, and the operating power in the same interval can be recorded as the same power, while the operating power in different intervals can be recorded as different powers. The span of each power interval can be the same or different, and can be selected based on actual conditions. The span size of each power interval can be selected based on actual conditions, for example, it can be 0.1kW, 1kW, or 3kW, etc.

[0049] For example, if the maximum power of an internal combustion engine is 185kW and the minimum power is 9kW, the range from 9kW to 185kW can be divided into several power intervals, each with the same span, perhaps 1kW. Thus, 9kW (inclusive) to 10kW (exclusive) is the first interval, 10kW (inclusive) to 11kW (exclusive) is the second interval, and so on. If the operating power of the internal combustion engine at a certain moment is 9.55kW, then this operating power is classified into the first interval. If the operating power of the internal combustion engine at multiple moments is 9.1kW, 9.2kW, 9.3kW, 9.4kW, and 9.5kW, respectively, these operating powers all fall into the first interval and are therefore considered the same. If the operating power of the internal combustion engine at multiple moments is 9.1kW, 10.2kW, and 11.4kW, respectively, these operating powers fall into different power intervals and are therefore considered different.

[0050] The actual accumulated sub-mileage corresponding to each operating power refers to the cumulative mileage driven by the hybrid engine at that operating power during the period between the moment the oil change completion signal is received and the moment the next oil change completion signal is received. In other words, the actual accumulated sub-mileage corresponding to each operating power is typically the total mileage driven by the hybrid vehicle equipped with the hybrid engine at that operating power over multiple trips.

[0051] Specifically, the monitoring of the actual accumulated sub-mileage of the hybrid engine corresponding to each operating power includes steps S111 to S114.

[0052] Step S111, sequentially obtaining the dashboard mileage of the hybrid vehicle and the actual speed and actual torque of the hybrid engine at preset time intervals; Step S112, determining the operating power of the hybrid engine at the starting time according to the actual speed and actual torque obtained at the starting time for each of the preset time intervals; and using the operating power at the starting time as the operating power for the preset time interval at the starting time. Step S113, determining the actual travel sub-mileage of the preset time interval formed by the start time and the end time based on the instrument panel mileage at the start time and the instrument panel mileage at the end time; Step S114 : determining the sum of the actual driving sub-mileages within the preset time interval at the same operating power as the actual accumulated sub-mileage at the operating power.

[0053] Regarding step S111 , the dashboard mileage of the hybrid vehicle and the actual speed and actual torque of the hybrid engine are sequentially obtained at preset time intervals.

[0054] During hybrid engine operation, the actual speed, torque, and mileage displayed on the instrument panel are collected at a preset frequency. The preset frequency can be every 0.1 seconds or every 1 second, depending on the actual situation. The smaller the preset frequency, the higher the collection frequency, which means a larger amount of data to be processed, but the operating power obtained will be more detailed. The larger the preset frequency, the lower the collection frequency, which means a smaller amount of data to be processed, but the operating power obtained will be more rough.

[0055] The preset time interval is the time interval between two adjacent collection moments. The first collection moment corresponding to each preset time interval is recorded as the start time of the preset time interval, and the first collection moment corresponding to each preset time interval is recorded as the end time of the preset time interval. It is important to note that for the first preset time interval, its end time is the start time of the second preset time interval. For each subsequent preset time interval, its start time is the end time of the previous adjacent preset time interval, and its end time is the start time of the next adjacent preset time interval.

[0056] At the start and end of each preset time interval, the hybrid vehicle's dashboard mileage, as well as the actual speed and actual torque of the hybrid engine, are collected. The dashboard mileage refers to the total mileage of the hybrid vehicle since it was manufactured.

[0057] Regarding step S112, for the start time and end time corresponding to each of the preset time intervals, the operating power of the hybrid engine at the start time is determined based on the actual speed and actual torque obtained at the start time; and the operating power at the start time is used as the operating power of the preset time interval at the start time.

[0058] The engine's operating power can be calculated based on the engine's speed and torque at the same time. The specific calculation formula is as follows:

[0059] Where P is operating power in kilowatts (kW); T is engine torque in Newton meters (N·m); n is engine speed in revolutions per minute (r / min); and 9550 is a conversion constant (derived from the unit conversion).

[0060] The operating power of the hybrid engine at that starting moment can be determined based on the actual speed and torque collected at the start of each preset time interval. That is, the operating power at each starting moment can be determined based on the actual speed and torque collected at each starting moment. Because the actual speed and torque are only collected at the start and end of each preset time interval, the operating power cannot be determined for the moments between the start and end of each preset time interval. Therefore, in this embodiment of the present application, the operating power corresponding to the start of each preset time interval is used as the operating power for that preset time interval. In other words, the operating power at the start is used as the operating power for each moment within the preset time interval.

[0061] Regarding step S113, the actual travel sub-mileage of the preset time interval formed by the start time and the end time is determined according to the instrument panel mileage at the start time and the instrument panel mileage at the end time.

[0062] Based on the dashboard mileage at the start and end of a preset time interval, the actual travel sub-mileage corresponding to that time interval can be calculated. Specifically, the difference between the dashboard mileage at the end and the dashboard mileage at the start is used as the actual travel sub-mileage corresponding to the preset time interval.

[0063] Regarding step S114 , the sum of the actual driving sub-mileages within the preset time interval with the same operating power is determined as the actual accumulated sub-mileage of the operating power.

[0064] For each different operating power, the sum of the actual driving sub-mileages within the preset time interval with the same operating power is determined as the actual cumulative sub-mileage of the operating power, thus obtaining the actual cumulative sub-mileage corresponding to each operating power.

[0065] For example, a hybrid vehicle has been running for one hour after receiving the oil change completion signal. For each preset time interval of one second within this hour, the instrument panel mileage and the actual speed and actual torque of the hybrid engine corresponding to the start and end times are collected to determine the operating power and actual driving sub-mileage corresponding to each second. Assuming that the operating powers include P11, P12, and P13, the actual driving sub-mileage corresponding to all preset time intervals with an operating power of P11 are added together to obtain the actual cumulative sub-mileage corresponding to the operating power P11; the actual driving sub-mileage corresponding to all preset time intervals with an operating power of P12 are added together to obtain the actual cumulative sub-mileage corresponding to the operating power P12; the actual driving sub-mileage corresponding to all preset time intervals with an operating power of P13 are added together to obtain the actual cumulative sub-mileage corresponding to the operating power P13.

[0066] Since the actual accumulated sub-mileage corresponding to each operating power changes with the driving of the hybrid vehicle after the current oil change completion signal is received and before the next oil change completion signal is received, each time the actual accumulated sub-mileage corresponding to at least one operating power is updated, steps S12 to S14 need to be executed to update the status of whether the oil needs to be changed.

[0067] For the actual accumulated sub-mileage corresponding to each operating power obtained at a certain moment, step S12 may be continued.

[0068] Regarding step S12 , the equivalent oil degradation sub-coefficient corresponding to each operating power is determined based on the preset oil replacement mileage corresponding to each operating power and the actual accumulated sub-mileage.

[0069] Before determining the equivalent oil degradation sub-coefficient corresponding to each operating power according to the preset oil change mileage corresponding to each operating power and the actual accumulated sub-mileage, the method further includes: A database containing preset oil change mileages is queried according to each operating power to determine the preset oil change mileage corresponding to each operating power; the preset oil change mileage corresponding to the operating power represents that after the hybrid vehicle changes the oil, it operates at the operating power until a deterioration coefficient of the replaced oil in the hybrid vehicle is greater than or equal to the preset oil change coefficient.

[0070] The preset oil change mileage corresponding to each operating power refers to the mileage corresponding to the hybrid vehicle operating stably at the operating power until the oil deteriorates to a state requiring replacement.

[0071] The database containing the preset oil change mileages is obtained by the following steps: After the test vehicle's oil is replaced, the i-th preset power in the data sequence containing N operating powers is used as the preset power. i is sequentially traversed from 1 to N, where i and N are both positive integers. For each preset power, perform the following steps: controlling the test vehicle to operate at a preset power; During the operation of the test engine of the test vehicle, sampling the engine oil of the test engine according to a preset period to determine a sample value of engine oil degradation of the test engine; When the oil degradation sample value is greater than or equal to the preset oil replacement coefficient, controlling the test vehicle to stop running; The mileage of the test vehicle after the oil is replaced and before the test vehicle stops running is determined as the preset oil replacement mileage corresponding to the preset power; the test vehicle and the hybrid vehicle are of the same type.

[0072] A test vehicle of the same type as the hybrid vehicle is used to conduct a durability test on the bench. Specifically, the test vehicle is controlled to operate stably at a preset power. The preset power can be the power of the hybrid engine of the hybrid vehicle within the range of maximum operating power and minimum operating power. In actual operation, since the power span between the maximum operating power and the minimum operating power is large, if each power is subjected to a bench test, the test cycle is too redundant. In order to solve this problem, the power of some points within the range of maximum operating power and minimum operating power can be selected for bench durability testing. For example, the power of 30 points can be selected for bench durability testing, and then the multiple preset oil change mileages obtained from the bench durability tests of these points are fitted, and then the preset oil change mileage corresponding to each operating power within the range of maximum operating power and minimum operating power is obtained, so as to shorten the test cycle of the bench durability test and improve the test efficiency.

[0073] While the test vehicle is operating at a preset power level, the engine oil is sampled at a preset interval to determine the degree of oil degradation and thereby obtain an oil degradation sample value. The preset interval can be set based on actual conditions, for example, every 50 hours or every 1,500 kilometers.

[0074] The step of sampling the engine oil of the test engine according to a preset period and determining a sample value of the engine oil degradation of the test engine includes: obtaining original engine oil parameters before the engine oil is injected into the test vehicle; obtaining current engine oil parameters of the engine oil sampled from the test engine each time; The oil degradation sample value corresponding to the test engine at each sampling time is determined according to the original oil parameter and the corresponding current oil parameter each time.

[0075] Based on the original oil parameters before injection into the test vehicle and the current oil parameters obtained at each sampling, an oil degradation sample value corresponding to each sampling can be determined. The oil degradation sample value can be expressed as the ratio of the current oil parameter degradation compared to the original oil parameter to the maximum allowable degradation of the oil, specifically expressed as a percentage.

[0076] When the oil degradation sample value obtained from a certain sampling is greater than or equal to the preset oil replacement coefficient, the test vehicle is controlled to stop running, and the bench endurance test for the current corresponding preset power is ended.

[0077] The total mileage of the test vehicle from the time the oil is added to the time the oil deterioration reaches its maximum value is recorded as the preset oil change mileage for the preset power. The maximum oil deterioration value, also referred to as the preset oil change coefficient in this embodiment, can be 100%.

[0078] Furthermore, determining the equivalent oil degradation sub-coefficient corresponding to each operating power according to the preset oil change mileage corresponding to each operating power and the actual accumulated sub-mileage includes: The ratio between the actual accumulated sub-mileage corresponding to each operating power and the corresponding preset oil replacement mileage is determined as the equivalent oil degradation sub-coefficient corresponding to each operating power.

[0079] Specifically, the actual accumulated sub-mileage corresponding to a certain operating power is divided by the corresponding preset oil change mileage. The resulting ratio is the equivalent oil degradation sub-factor for that operating power. The equivalent oil degradation sub-factor can be expressed as a percentage.

[0080] The embodiment of the present application determines the contribution of the driving condition of each operating power to the oil degradation (that is, the equivalent oil degradation sub-coefficient) based on the actual accumulated sub-mileage corresponding to each operating power and the corresponding preset oil change mileage.

[0081] For example, the operating power levels are P1, P2, P3, P4, P5, and P6, and the corresponding preset oil change mileages are L1, L2, L3, L4, L5, and L6. The hybrid engine's operating power levels since the last oil change are P1, P2, P3, P4, P5, and P6, and the corresponding actual accumulated sub-mileages are K1, K2, K3, K4, K5, and K6. The contribution of each operating power level to oil degradation (i.e., the equivalent oil degradation sub-coefficient) is K1 / L1, K2 / L2, K3 / L3, K4 / L4, K5 / L5, and K6 / L6, respectively.

[0082] Regarding step S13 , the actual oil degradation coefficient of the hybrid engine is determined based on the equivalent oil degradation sub-coefficients corresponding to the respective operating powers.

[0083] The actual oil degradation coefficient of the hybrid engine is determined by adding the equivalent oil degradation sub-coefficients corresponding to each operating power. In other words, by adding the contribution of each operating power to oil degradation, the total contribution of all operating conditions of the hybrid engine to oil degradation, after receiving the oil change completion signal and before the current moment, is obtained, which is the actual oil degradation coefficient.

[0084] For example, the operating power levels are P1, P2, P3, P4, P5, and P6, and their corresponding preset oil change mileages are L1, L2, L3, L4, L5, and L6. The hybrid engine's operating power levels since the last oil change are P1, P2, P3, P4, P5, and P6, and their corresponding actual accumulated sub-mileages are K1, K2, K3, K4, K5, and K6. The contribution of each operating power level to oil degradation (i.e., the equivalent oil degradation sub-coefficient) is K1 / L1, K2 / L2, K3 / L3, K4 / L4, K5 / L5, and K6 / L6, respectively. The sum of K1 / L1, K2 / L2, K3 / L3, K4 / L4, K5 / L5, and K6 / L6 is the actual oil degradation sub-coefficient at the current moment.

[0085] Regarding step S14 , when the actual engine oil degradation coefficient is greater than or equal to the preset engine oil replacement coefficient, an engine oil replacement reminder signal is output.

[0086] The preset oil change factor may be 100%.

[0087] A determination is made as to whether the actual oil degradation coefficient is greater than or equal to a preset oil change coefficient. If so, indicating that the oil requires timely replacement, an oil change reminder signal is output, which may be voice-activated, to remind the user to promptly replace the oil. If the actual oil degradation coefficient is less than the preset oil change coefficient, steps S11 through S14 are executed again until the next oil change completion signal is received, at which point steps S11 through S14 are repeated.

[0088] In summary, the present embodiment monitors the actual accumulated sub-mileage of the hybrid engine at various operating power levels in response to each oil change completion signal from the hybrid engine of a hybrid vehicle; determines the equivalent oil degradation sub-coefficient corresponding to each operating power level based on the preset oil change mileage and the actual accumulated sub-mileage; determines the actual oil degradation coefficient of the hybrid engine based on the equivalent oil degradation sub-coefficient corresponding to each operating power level; and outputs an oil change reminder signal if the actual oil degradation coefficient is greater than or equal to the preset oil change coefficient. Thus, the present embodiment quantifies the contribution of the actual accumulated sub-mileage corresponding to each operating power level to oil degradation, accumulates the degree of oil degradation of the hybrid engine at each operating power level, and determines whether an oil change is necessary based on the actual operating conditions of the hybrid engine. This improves the accuracy of the hybrid engine's oil change reminder, effectively extending the oil change cycle, improving oil utilization, reducing oil waste, and lowering oil replacement costs.

[0089] Furthermore, in addition to the aforementioned impact of hybrid engine load on oil change intervals, another factor influencing the oil change interval is the water content in the oil. Increased water content in the oil can, in severe cases, cause corrosion of metal components within the engine. It can also lead to poor lubrication and accelerated engine wear. In winter or other low-temperature conditions, when hybrid vehicles are frequently started and the engine is not fully warmed up, the water content in the oil can increase dramatically, impacting the hybrid engine's service life and compromising the lubrication effectiveness of the oil.

[0090] In order to solve the above problems, the embodiment of the present application further provides the following optimization method based on the above-mentioned oil maintenance monitoring method, which is specifically executed after the hybrid vehicle receives a start command each time. The method includes steps S21 to S24, such as Figure 2 shown.

[0091] Step S21, in response to a start instruction of the hybrid vehicle, obtaining an actual ambient temperature of an environment in which the hybrid vehicle is located; Step S22, when the actual ambient temperature is lower than a preset ambient temperature, obtaining historical operating data of the hybrid engine within a first historical period; the end time of the first historical period is the time when the hybrid vehicle responds to the start instruction; Step S23, determining whether the historical operating data satisfies a preset operating condition, where the preset operating condition refers to the actual speed of the hybrid engine exceeding a preset speed and lasting for a time period greater than or equal to a first preset time period, or the preset operating condition refers to the actual water temperature of the hybrid engine exceeding a preset water temperature and lasting for a time period greater than or equal to a second preset time period; Step S24: When the historical operating data does not satisfy the preset operating condition, a reminder signal is output to force the hybrid engine to operate.

[0092] Regarding step S21 , in response to a start instruction of the hybrid vehicle, an actual ambient temperature of an environment in which the hybrid vehicle is located is acquired.

[0093] In response to the start-up command of the hybrid vehicle, the actual ambient temperature of the current environment of the hybrid vehicle is obtained to determine whether the hybrid vehicle is in a low-temperature environment. Specifically, the actual ambient temperature is compared with the preset ambient temperature. If the actual ambient temperature is lower than the preset ambient temperature, it is determined that the hybrid vehicle is in a low-temperature environment, and then step S22 can be continued. If the actual ambient temperature is greater than or equal to the preset ambient temperature, it is determined that the hybrid vehicle is not in a low-temperature environment. The preset ambient temperature can be selected according to actual conditions, for example, it can be 1°C, 5°C, 10°C, etc. The higher the preset ambient temperature is set, the easier it is to trigger the execution of steps S21-step S23 provided in the embodiment of the present application, which can also ensure that the water content of the engine oil is relatively low to a certain extent.

[0094] Regarding step S22, when the actual ambient temperature is lower than the preset ambient temperature, historical operating data of the hybrid engine in a first historical period is obtained; the end time of the first historical period is the time when the hybrid vehicle responds to the start instruction.

[0095] The first historical period may be a time period starting from the moment when the hybrid vehicle responds to the start instruction and having a third preset duration. The third preset duration may be set according to actual conditions, for example, 15 days.

[0096] The historical operating data matches the preset operating condition, and the preset operating condition and the historical operating data will be described in step S23.

[0097] After obtaining the historical operating data of the hybrid engine in the first historical period, step S23 may be continued.

[0098] Regarding step S23, it is determined whether the historical operating data meets the preset operating conditions, where the preset operating conditions refer to the actual speed of the hybrid engine exceeding the preset speed and lasting for a time greater than or equal to a first preset time, or the preset operating conditions refer to the actual water temperature of the hybrid engine exceeding the preset water temperature and lasting for a time greater than or equal to a second preset time.

[0099] Define the preset operating condition. The preset operating condition refers to the operating condition in which the hybrid engine can minimize the water content in the engine oil. There are two specific ways to measure whether it is the preset operating condition.

[0100] One approach is to measure the hybrid engine's speed. If the hybrid engine's actual speed exceeds a preset speed for a duration greater than or equal to a first preset time, the hybrid engine is considered to have met the preset operating condition. The preset speed can be a relatively high speed, specifically exceeding 1000 rpm. The first preset time can be 3 minutes or longer, for example, 10 minutes.

[0101] Another approach is to measure the engine's water temperature. If the hybrid engine's actual water temperature exceeds a preset temperature and remains above a second preset time, the hybrid engine is considered to have met the preset operating condition. The preset water temperature can be 90°C or higher, and the second preset time can be 3 minutes or longer, for example, 10 minutes.

[0102] The specific data included in the historical operating data depends primarily on whether the preset operating conditions are measured using speed or water temperature. If speed is used to measure the preset operating conditions, the historical operating data may include: the hybrid engine's actual speed during the first historical period and the duration that the actual speed exceeded the preset speed. If water temperature is used to measure the preset operating conditions, the historical operating data may include: the hybrid engine's actual water temperature during the first historical period and the duration that the actual water temperature exceeded the preset water temperature.

[0103] Regarding step S24 , when the historical operating data does not satisfy the preset operating condition, a reminder signal forcing the hybrid engine to operate is output.

[0104] If historical operating data does not meet the preset operating conditions, a reminder signal can be output to force the hybrid engine to operate, alerting the user that the hybrid engine's oil needs to be warmed up. If historical operating data does not meet the preset operating conditions, this indicates that the hybrid vehicle's hybrid engine's oil needs to be dehydrated promptly. This means controlling the hybrid engine's operation until the preset operating conditions are met. By forcing the hybrid engine to operate, moisture in the oil evaporates into the crankcase and is discharged through the crankcase ventilation system, thereby reducing the oil's water content.

[0105] The aforementioned steps S21 to S24 may also be specifically performed in the following implementation manner. The main difference lies in step S22, which, when the actual ambient temperature is lower than the preset ambient temperature, obtains historical operating data of the hybrid engine within the first historical period, including: When the actual ambient temperature is lower than the preset ambient temperature, determining whether the duration of the first historical period exceeds a third preset duration; When the duration of the first historical period exceeds the third preset duration, the historical operating data of the hybrid engine in the first historical period is obtained.

[0106] In combination with the above content, in order to distinguish it from the first historical period in step S22, in steps SA1 to SA3, the first historical period is replaced by the third historical period.

[0107] Step SA1, in response to a start instruction of the hybrid vehicle, obtaining an actual ambient temperature of an environment in which the hybrid vehicle is located; Step SA2: When the actual ambient temperature is less than a preset ambient temperature and the third historical period exceeds a third preset duration, obtaining historical operating data corresponding to the hybrid engine within the third historical period; the third historical period is the period between the time when the hybrid engine last met a preset operating condition and the time when the start command is currently received, the preset operating condition being when the actual speed of the hybrid engine exceeds a preset speed and lasts for a period greater than or equal to a first preset duration, or the preset operating condition being when the actual water temperature of the hybrid engine exceeds a preset water temperature and lasts for a period greater than or equal to a second preset duration; Step SA3: If the historical operating data does not satisfy the preset operating condition, outputting a reminder signal forcing the hybrid engine to operate.

[0108] Regarding step SA1, in response to the start-up instruction of the hybrid vehicle, the actual ambient temperature of the current environment of the hybrid vehicle is obtained to determine whether the hybrid vehicle is in a low-temperature environment. Specifically, the actual ambient temperature is compared with the preset ambient temperature. If the actual ambient temperature is lower than the preset ambient temperature, it is determined that the hybrid vehicle is in a low-temperature environment, and then step SA2 can be continued. If the actual ambient temperature is greater than or equal to the preset ambient temperature, it is determined that the hybrid vehicle is not in a low-temperature environment. The preset ambient temperature can be selected according to actual conditions, for example, it can be 1°C, 5°C, 10°C, etc. The higher the preset ambient temperature is set, the easier it is to trigger the execution of steps SA1 to SA3 provided in the embodiment of the present application, and to a certain extent, it can ensure that the water content of the engine oil is relatively low.

[0109] Regarding step SA2, a preset operating condition is first defined. The preset operating condition refers to an operating condition in which the hybrid engine can minimize the water content in the engine oil. Specifically, two methods can be used to measure whether it is the preset operating condition.

[0110] One approach is to measure the hybrid engine's speed. If the hybrid engine's actual speed exceeds a preset speed for a duration greater than or equal to a first preset time, the hybrid engine is considered to have met the preset operating condition. The preset speed can be a relatively high speed, specifically exceeding 1000 rpm. The first preset time can be 3 minutes or longer, for example, 10 minutes.

[0111] Another approach is to measure the engine's water temperature. If the hybrid engine's actual water temperature exceeds a preset temperature and remains above a second preset time, the hybrid engine is considered to have met the preset operating condition. The preset water temperature can be 90°C or higher, and the second preset time can be 3 minutes or longer, for example, 10 minutes.

[0112] Next, a third historical period is defined. In this embodiment, the period between the last time the hybrid engine met the preset operating conditions and the moment the start command is currently received is recorded as the third historical period. The last time the preset operating conditions were met is a pre-stored time, which will be described in detail later.

[0113] Finally, step SA2 is explained. When the third historical period exceeds the third preset duration, the historical operating data of the hybrid engine in the third historical period is obtained. The third preset duration can be set according to actual conditions, for example, it can be 15 days. What specific data the historical operating data includes is mainly based on whether the speed angle is selected to measure the preset operating conditions or the water temperature angle is selected to measure the preset operating conditions. If the speed angle is used to measure the preset operating conditions, the historical operating data may include: the actual speed of the hybrid engine in the third historical period and the duration that the actual speed exceeds the preset speed. If the water temperature angle is used to measure the preset operating conditions, the historical operating data may include: the actual water temperature of the hybrid engine in the third historical period and the duration that the actual water temperature exceeds the preset water temperature.

[0114] Regarding step SA3 , if the historical operating data does not meet the preset operating conditions, a reminder signal forcing the hybrid engine to operate may be output to remind the user that the hybrid engine oil needs to be warmed up for maintenance.

[0115] In other words, if the period between the last time the hybrid engine met the preset operating conditions and the current time exceeds the third preset duration, the hybrid vehicle's hybrid engine's oil needs to be dehydrated. This means the hybrid engine is forced to operate until the preset operating conditions are met. By forcing the hybrid engine to run, moisture in the oil evaporates into the crankcase and is discharged through the crankcase ventilation system, thereby reducing the oil's water content.

[0116] Furthermore, the embodiment of the present application also provides another solution, which is applicable to the situation where the historical operating data does not meet the preset working conditions, specifically: When the historical operating data does not satisfy the preset operating condition, obtaining navigation data input by the user; determining target driving data of the hybrid vehicle according to the navigation data; the target driving data including at least one of an expected driving mileage and an expected driving duration; When the target driving data exceeds the preset driving data, controlling the internal combustion engine of the hybrid engine to travel according to a trend that satisfies the preset operating condition; When the target driving data does not exceed the preset driving data, a reminder signal for forcing the hybrid engine to operate is output.

[0117] Based on the target driving data in the navigation data entered by the user, such as the estimated mileage and / or estimated driving duration, a determination is made as to whether the target driving data exceeds the preset driving data. The preset driving data is based on the aforementioned preset operating conditions and specifically refers to the base driving mileage and / or base driving duration corresponding to the hybrid engine being able to achieve the preset operating conditions.

[0118] If the target driving data exceeds the preset driving data, the internal combustion engine of the hybrid vehicle will be directly controlled to operate while the hybrid vehicle is driving according to the navigation, regardless of the remaining power of the hybrid vehicle's power battery, so that the internal combustion engine drives according to the trend of meeting the preset operating conditions. As the internal combustion engine runs, when the state of the internal combustion engine meets the preset operating conditions, conventional driving mode can be used, that is, the electric motor and internal combustion engine provide power according to actual driving needs.

[0119] If the target driving data does not exceed the preset driving data, a reminder signal is output to force the hybrid engine to operate, reminding the user that the hybrid engine's oil needs to be warmed up. This can be done via voice notification, and the specific content can be customized based on actual circumstances. For example, it could be: "The engine was recently briefly started in a non-warm-up state, and it is recommended that the hybrid vehicle remain in operation to drain the hybrid engine's oil and extend its lifespan."

[0120] Furthermore, after the aforementioned output of the reminder signal forcing the hybrid engine to operate, the method further includes steps S31 to S33.

[0121] Step S31, in response to a shutdown command of the hybrid vehicle, determining whether the hybrid engine has an operating state that satisfies the preset operating condition in a second historical period; the second historical period being the period between the time when the start command was last received and the time when the shutdown command was last received; Step S32: accumulating the number of times the reminder signal forcing the hybrid engine to operate is output when the operating state meeting the preset operating condition does not exist in the second historical period; Step S33: when there is an operating state that meets the preset operating condition in the second historical period, the output times are cleared.

[0122] Regarding step S31, in response to the shutdown command of the hybrid vehicle, it is determined whether the hybrid engine has an operating state that meets the preset operating conditions in a second historical period; the second historical period refers to the period between the time when the start command was last received and the time when the shutdown command was last received.

[0123] First, a second historical period is defined. The second historical period is the period between the time the start command was most recently received and the time the shutdown command was most recently received. When the hybrid vehicle receives the shutdown command, it is determined whether the hybrid engine has been operating in a state that meets a preset operating condition within the second historical period.

[0124] Regarding step S32 , when there is no operating state that meets the preset operating condition during the second historical period, the number of outputs of the reminder signal forcing the hybrid engine to operate is accumulated.

[0125] If the second historical period does not have an operating state that meets the preset operating condition, it is considered that the user has not responded to the reminder signal for forcing the hybrid engine to run, and the number of times the reminder signal is output is accumulated.

[0126] Regarding step S33, when there is an operating state that meets the preset operating condition in the second historical period, the output times are cleared to zero.

[0127] If there is an operating state that meets the preset operating condition in the second historical period, it is considered that the user has performed a hot engine maintenance operation on the hybrid engine in accordance with the reminder signal for forcing the hybrid engine to run, that is, the user has performed a forced dewatering operation on the engine oil. The number of outputs of the reminder signal is reset to zero, and the time when the shutdown command was most recently received is used as the updated time when the preset operating condition was last met, and the updated time when the preset operating condition was last met is stored for use in the aforementioned step SA2.

[0128] After each hybrid vehicle receives and responds to the start command, the method further includes: determining whether the output frequency of the reminder signal forcing the hybrid engine to operate exceeds a preset frequency; When the output times exceed the preset times, an oil change reminder signal is output.

[0129] The preset number of times can be 3 times, and the oil change reminder signal is output, which can be played through voice to remind the user to change the oil in time.

[0130] In summary, in response to a start command of the hybrid vehicle, the embodiment of the present application obtains the actual ambient temperature of the environment in which the hybrid vehicle is located; when the actual ambient temperature is less than a preset ambient temperature, historical operating data of the hybrid engine within a first historical period is obtained; the end time of the first historical period is the time when the hybrid vehicle responds to the start command; it is determined whether the historical operating data meets a preset operating condition, where the preset operating condition refers to the actual speed of the hybrid engine exceeding the preset speed and the duration is greater than or equal to a first preset duration, or the preset operating condition refers to the actual water temperature of the hybrid engine exceeding the preset water temperature and the duration is greater than or equal to a second preset duration; and when the historical operating data does not meet the preset operating condition, a reminder signal is output to force the hybrid engine to operate. It can be seen that the embodiment of the present application monitors the operating conditions of the hybrid engine of a hybrid vehicle in a low-temperature environment. If the hybrid engine does not have a driving state that meets the preset operating conditions for a long time, it is considered that the water content in the engine oil may be high. Therefore, the hybrid engine can be forced to operate at a higher load during the user's driving process to reduce the water content in the engine oil, extend the service life of the engine oil, and reduce the degree of corrosion caused by the water in the engine oil to the engine.

[0131] Based on the same inventive concept, the present application provides the following embodiments: Figure 3 A hybrid vehicle monitoring device is shown, the device comprising: an actual accumulated sub-mileage determining module 31 for monitoring the actual accumulated sub-mileage corresponding to each operating power of the hybrid engine of the hybrid vehicle in response to an oil change completion signal of the hybrid engine; an equivalent oil degradation sub-coefficient determining module 32 for determining the equivalent oil degradation sub-coefficient corresponding to each operating power according to the preset oil change mileage corresponding to each operating power and the actual accumulated sub-mileage; an actual oil degradation coefficient determination module 33 for determining an actual oil degradation coefficient of the hybrid engine according to the equivalent oil degradation sub-coefficients corresponding to the respective operating powers; The oil change reminder module 34 is configured to output an oil change reminder signal when the actual oil degradation coefficient is greater than or equal to a preset oil change coefficient.

[0134] In some embodiments of the present application, based on the aforementioned solution, the device further includes a preset oil change mileage acquisition module, which is used to: Before determining the equivalent oil deterioration sub-coefficient corresponding to each operating power based on the preset oil change mileage corresponding to each operating power and the actual accumulated sub-mileage, a database containing preset oil change mileages is queried based on each operating power to determine the preset oil change mileage corresponding to each operating power; the preset oil change mileage corresponding to the operating power represents that after the hybrid vehicle has changed its oil, it operates at the operating power until the deterioration coefficient of the oil replaced in the hybrid vehicle is greater than or equal to the preset oil change coefficient.

[0135] In some embodiments of the present application, based on the aforementioned scheme, the device also includes a preset oil change mileage determination module, which is used to: after the test vehicle changes its oil, use the i-th preset power in the data sequence containing N operating powers as the preset power, i traverses from 1 to N in sequence, i and N are both positive integers, and perform the following steps for each preset power: control the test vehicle to operate at the preset power; during the operation of the test engine of the test vehicle, sample the oil of the test engine according to a preset period to determine the oil deterioration sample value of the test engine; when the oil deterioration sample value is greater than or equal to the preset oil change coefficient, control the test vehicle to stop running; determine the mileage of the test vehicle in the period from the oil change to the stop of the test vehicle as the preset oil change mileage corresponding to the preset power; the test vehicle and the hybrid vehicle are of the same type.

As long as those skilled in the art implement the electronic device used by the information processing method in the embodiment of this application, it falls within the scope of protection to be provided by this application.

[0147] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: In response to each oil change completion signal from the hybrid engine of a hybrid vehicle, the present embodiment monitors the actual accumulated sub-mileage of the hybrid engine at various operating power levels; determines the equivalent oil degradation sub-coefficient corresponding to each operating power level based on the preset oil change mileage and the actual accumulated sub-mileage; determines the actual oil degradation coefficient of the hybrid engine based on the equivalent oil degradation sub-coefficient corresponding to each operating power level; and outputs an oil change reminder signal if the actual oil degradation coefficient is greater than or equal to the preset oil change coefficient. Thus, the present embodiment quantifies the contribution of the actual accumulated sub-mileage corresponding to each operating power level to oil degradation, accumulates the degree of oil degradation of the hybrid engine at each operating power level, and determines whether an oil change is necessary based on the actual operating conditions of the hybrid engine. This improves the accuracy of the hybrid engine's oil change reminder, effectively extending the oil change cycle, increasing oil utilization, reducing oil waste, and lowering oil replacement costs.

[0148] In an embodiment of the present application, in response to a start-up command of the hybrid vehicle, an actual ambient temperature of the environment in which the hybrid vehicle is located is obtained; when the actual ambient temperature is less than a preset ambient temperature, historical operating data of the hybrid engine within a first historical period is obtained; the end time of the first historical period is the time when the hybrid vehicle responds to the start-up command; it is determined whether the historical operating data meets a preset operating condition, where the preset operating condition refers to an actual speed of the hybrid engine exceeding a preset speed and lasting for a time period greater than or equal to a first preset time period, or the preset operating condition refers to an actual water temperature of the hybrid engine exceeding a preset water temperature and lasting for a time period greater than or equal to a second preset time period; and when the historical operating data does not meet the preset operating condition, a reminder signal is output to force the hybrid engine to operate.
