[0003] With the rapid development of new energy vehicles, hybrid vehicles are very popular. For hybrid vehicles, the engine inside the vehicle can perform multiple functions.

[0004] In related technologies, when the battery power of a hybrid vehicle is too low, the hybrid vehicle can start the engine to charge the battery. It can also start the engine when the hybrid vehicle needs to accelerate rapidly, so that the engine and the electric motor work together to drive the vehicle to meet the vehicle's power requirements.

[0005] However, when a hybrid vehicle is driven solely by the electric motor and the battery is always fully charged, the engine may not start for extended periods, which can lead to corrosion of internal engine parts and emulsification and deterioration of the engine oil, thus affecting the engine's lifespan.

[0030] When the vehicle's engine is not started and the time difference between the last engine start and the current time meets a specified duration, the vehicle control unit can obtain information such as the engine fuel tank level, the vehicle's total mileage, and the vehicle speed. If all three conditions are met, the vehicle's engine is started, entering self-maintenance mode. After starting, the internal engine parts operate, increasing the flow of lubricating oil and thus fully lubricating the internal engine components, achieving a maintenance effect. Furthermore, when the engine coolant temperature reaches a specified temperature, the engine is controlled to exit self-maintenance mode to avoid unnecessary power consumption. Additionally, if the engine fuel tank level and vehicle speed information...

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0040] Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] This application proposes an engine starting scheme that enables the engine of a hybrid vehicle to enter a self-maintenance mode without starting, provided certain conditions are met, thereby extending the engine's service life. For ease of understanding, some concepts involved in this application are explained below.

[0042] 1) A hybrid vehicle is a car that is equipped with both a traditional internal combustion engine (usually a gasoline or diesel engine) and an electric motor (electric motor) as power sources. This type of vehicle combines the engine and the electric motor to drive the vehicle, aiming to improve fuel efficiency and reduce emissions.

[0043] 2) HEV (Hybrid Electric Vehicle) mode is an operating mode for hybrid electric vehicles. In this mode, the vehicle automatically adjusts the combination of internal combustion engine (usually a gasoline or diesel engine) and electric motor according to actual driving conditions to achieve optimal fuel efficiency and performance.

[0044] 3) EV (Electric Vehicle) mode is an operating mode in which the vehicle relies entirely on the power provided by the electric motor for propulsion, without using the internal combustion engine. In this mode, the vehicle is powered and driven solely by the electric motor to achieve zero emissions.

[0045] 4) CAN (Controller Area Network) is a serial communication protocol bus standard for real-time applications. A CAN network allows multiple nodes on the network to send information simultaneously; any node can be a sender or receiver of messages.

[0046] It should be noted that this application may display prompt interfaces, pop-ups, or output voice prompts before and during the collection of user-related data (such as the engine start time of a vehicle). These prompt interfaces, pop-ups, or voice prompts are used to inform the user that their relevant data is being collected. This ensures that the application only begins the steps for collecting user-related data after receiving confirmation from the user regarding the prompt interface or pop-up; otherwise (i.e., without user confirmation), the steps for collecting user-related data end, meaning no user-related data is collected. In other words, all user data collected in this application is collected with the user's consent and authorization, and the collection, use, and processing of relevant user data must comply with the relevant laws, regulations, and standards of the relevant countries and regions.

[0047] Figure 1 is a system configuration diagram of an engine starting method according to an embodiment of this application. As shown in Figure 1, the hybrid vehicle 100 includes a vehicle control unit 100a, an engine 100b, and an instrument panel 100c.

[0048] In the system shown in Figure 1, the vehicle control unit 100a in the hybrid vehicle 100 monitors the start time of the engine 100b. When the engine 100b is not started, the vehicle control unit 100a can obtain the current time from the GPS (Global Positioning System) signal data corresponding to the hybrid vehicle 100, and subtract it from the last start time of the engine 100b to obtain the time difference between the current time and the last start time of the engine 100b. If the time difference is greater than a specified time difference, the vehicle control unit 100a obtains the engine fuel tank level, total mileage, and vehicle speed information of the hybrid vehicle 100. Historical time can be obtained through the non-volatile memory 01 corresponding to the hybrid vehicle 100. The hybrid vehicle 100 can obtain the engine fuel tank level information through the fuel pump control unit 02, the total mileage information through the instrument panel control unit 03, and the current vehicle speed information through the transmission system control unit 04.

[0049] When the engine fuel tank level, total mileage, and speed of the vehicle meet their respective specified conditions, the vehicle control unit 100a controls the engine 100b to enter a self-maintenance mode initiated for the purpose of engine maintenance. After entering the self-maintenance mode, the vehicle control unit 100a continuously monitors the temperature of the coolant in the engine 100b. If the coolant temperature exceeds a specified temperature, the vehicle control unit 100a controls the engine 100b to exit the self-maintenance mode.

[0050] If at least one of the engine fuel tank level and vehicle speed information fails to meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message will be displayed on the vehicle's instrument panel 100c to remind the user to actively start the engine for engine maintenance.

[0051] Figure 2 is a flowchart of an engine starting method according to an embodiment of this application. This engine starting method can be executed by the vehicle control unit in the hybrid vehicle, or by the computer device corresponding to the hybrid vehicle control unit. For example, the computer device can be the vehicle control unit 100a shown in Figure 1 above, or it can be other computer devices, such as a server, or a personal computer, etc. The engine starting method may include the following steps.

[0052] Step 210: When the vehicle's engine is not started and the time difference is greater than the specified time difference, obtain the current engine fuel tank level information, total mileage information, and vehicle speed information of the vehicle; the time difference is the difference between the current time and the historical time, and the historical time is the time when the vehicle's engine was last started.

[0053] In this embodiment of the application, when the hybrid vehicle is driven by an electric motor and there is no need to start the engine to charge the electric motor or provide driving force for the vehicle (e.g., rapid acceleration or high-speed driving), the vehicle control unit obtains the time of the last engine start of the hybrid vehicle (i.e., historical time) and the current time, and obtains the time difference by the difference between the last engine start time and the current time.

[0054] In this embodiment, the vehicle control unit can read the engine's last start time from the non-volatile memory (NVM) in the vehicle's engine control module (ECU), or it can read the engine's last start time from the cloud server corresponding to the vehicle control unit. The vehicle control unit can obtain the current time from the GPS signal data acquired by the vehicle.

[0055] Optionally, the vehicle control unit can send a fuel tank level request to the vehicle's fuel pump control unit via the CAN bus to obtain fuel tank level information.

[0056] Optionally, the vehicle control unit can send a total mileage request to the vehicle's instrument panel control unit via the CAN bus to obtain the total mileage information. Alternatively, the driver can directly observe the data displayed on the instrument panel to obtain the corresponding total mileage information.

[0057] Optionally, the vehicle control unit can send a speed acquisition request to the vehicle's drivetrain control unit via the CAN bus to obtain the current vehicle speed information. Alternatively, the driver can directly observe the data displayed on the instrument panel to obtain the vehicle's current speed information.

[0058] In this embodiment of the application, the vehicle control unit of the hybrid vehicle acquires three vehicle-related information items when the vehicle's engine is not started and the time difference is greater than a specified time difference, so as to facilitate the subsequent engine start of the vehicle. By combining multiple factors to determine whether to start the engine, the engine start strategy is optimized to ensure that the engine starts when necessary, while also avoiding the problem of accidental start.

[0059] Step 220: When the engine fuel tank level, total mileage, and speed of the vehicle meet their respective specified conditions, control the engine to enter self-maintenance mode; self-maintenance mode is a mode initiated for the purpose of maintaining the engine.

[0060] The specified conditions corresponding to the engine fuel tank level of the aforementioned vehicle may include that the amount of fuel corresponding to the engine fuel tank level is sufficient to support the hybrid vehicle's engine to start and run continuously for a specified period of time. For example, the conditions corresponding to the fuel amount may include: the amount of engine fuel stored in the vehicle is not less than 10% of the total fuel tank level.

[0061] The specified conditions corresponding to the total mileage of the above-mentioned vehicles may include the total mileage being no less than a certain specified threshold. For example, the specified conditions corresponding to the total mileage of the above-mentioned vehicles may include: the total mileage of the vehicles is no less than 1000km.

[0062] The specified conditions corresponding to the vehicle speed mentioned above may include a speed that is not lower than a certain specified threshold. For example, the specified conditions corresponding to the vehicle speed mentioned above may include: the current vehicle speed is higher than 30km / h.

[0063] In this embodiment, the self-maintenance condition described above is for engine maintenance. When the vehicle meets specified conditions, the vehicle control unit executes relevant maintenance procedures to control engine startup and achieve engine maintenance. This engine-maintenance-oriented startup condition can refer to a situation where the vehicle is driven by an electric motor, the power provided by the electric motor meets the vehicle's current power needs (e.g., the vehicle is not traveling at high speed, or the vehicle is not accelerating rapidly), and the vehicle's battery has sufficient charge. Whether the vehicle's battery is sufficiently charged can be determined using a charge percentage threshold. For example, if the battery percentage is below this threshold, the engine will be triggered to charge the battery; if the battery percentage is above the threshold, it can be determined that the vehicle's battery has sufficient charge.

[0064] In this embodiment of the application, by limiting the vehicle's engine to start when the fuel level in the engine tank meets a specified condition, it can be ensured that there is enough fuel in the engine to support engine start-up and maintain operation for a specified duration. At the same time, if the vehicle speed driven by the electric motor meets a specified speed, starting the engine at this time can make the driver feel that it is reasonable.

[0065] Step 230: If the temperature of the coolant in the engine is higher than the specified temperature, control the engine to exit the self-maintenance mode.

[0066] In this embodiment of the application, after the engine enters the self-maintenance mode, the vehicle control unit can monitor the temperature of the coolant through the temperature sensor in the engine cooling system. After obtaining the temperature of the coolant, it compares it with a preset specified temperature (e.g., 85°C). If the temperature of the coolant is greater than the specified temperature, the vehicle control unit controls the engine to exit the self-maintenance mode.

[0067] In this embodiment, after the engine enters the self-maintenance mode, the heat generated during engine startup causes the lubricating oil to form a protective film inside the engine, preventing direct contact between internal engine components. The higher temperature makes the lubricating oil thinner and increases its fluidity, thereby covering a wider area of ​​internal parts and ensuring that the internal engine components are adequately lubricated. Based on this, when the temperature of the coolant in the engine reaches a specified temperature, it indicates that the engine has completed self-maintenance. By limiting the specified temperature conditions, the engine can exit the self-maintenance mode, ensuring that the engine is effectively lubricated while avoiding unnecessary engine operation, thereby achieving efficient engine maintenance.

[0068] Step 240: If at least one of the engine fuel tank level and vehicle speed information does not meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message is displayed on the vehicle's instrument panel. The first reminder message is used to remind the user to actively start the engine to perform engine maintenance.

[0069] In this embodiment of the application, when the total mileage of the vehicle meets the corresponding specified conditions, and the engine fuel tank level meets the specified conditions or the vehicle speed information meets the specified speed, a first reminder message is displayed on the vehicle's instrument panel.

[0070] It should be noted that, in the embodiments of this application, the first reminder message used to remind the user to actively start the engine for engine maintenance is not limited to being displayed on the vehicle's dashboard. It can also be prompted to the user through at least one of the following methods: voice broadcast, vibration of the vehicle's steering wheel or driver's seat, color of the vehicle's interior lights, or a mobile device bound to the vehicle (such as a mobile phone connected to the vehicle via Bluetooth).

[0071] Optionally, if at least one of the engine fuel tank level and vehicle speed information does not meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message is played through the vehicle's audio equipment. The first reminder message is used to remind the user to actively start the engine to perform engine maintenance.

[0072] For example, if the engine fuel tank level is below a specified condition, but the total mileage meets the specified condition, the vehicle's audio system will play the corresponding voice message for the first reminder, such as "Engine fuel level is low, please add fuel!", to remind the user to add fuel to the engine so that the engine fuel tank level meets the specified condition. The voice message will stop playing once the engine fuel tank level meets the specified condition.

[0073] For example, if the current vehicle speed does not meet the specified speed, but the total mileage information meets the specified conditions, the vehicle's audio equipment plays the voice content corresponding to the first reminder message, such as "The current speed is too low, please accelerate!", to remind the user to accelerate so that the current speed meets the specified conditions. The voice content played by the audio equipment stops playing after the vehicle speed meets the specified conditions.

[0074] Optionally, if at least one of the engine fuel tank level and vehicle speed information does not meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message is issued through vibration of the vehicle's steering wheel or driver's seat. The first reminder message is used to remind the user to actively start the engine to perform engine maintenance.

[0075] It should be noted that in the above embodiment of the application, vibration is emitted when the steering wheel detects that the user's hands are on the steering wheel; and vibration is emitted when the driver's seat detects that the user is sitting in the driver's seat.

[0076] For example, if the engine fuel tank level is below a specified condition, but the total mileage meets the specified condition, the vehicle control unit detects that the user is sitting in the driver's seat. At this time, the driver's seat vibrates. The intensity of the vibration is positively correlated with the difference between the current engine fuel tank level and the specified condition. The greater the difference between the current engine fuel tank level and the specified condition, the greater the vibration intensity, in order to remind the user to add engine fuel. After the engine fuel tank level meets the specified condition after adding fuel, the vibration disappears.

[0077] For example, if the current vehicle speed does not meet the specified speed, but the total mileage information meets the specified conditions, the vehicle control unit detects that the user is sitting in the driver's seat. At this time, the driver's seat vibrates, and the vibration intensity is inversely proportional to the current vehicle speed. The lower the current vehicle speed, the greater the vibration intensity, in order to remind the user to accelerate. Once the current vehicle speed meets the specified speed, the vibration disappears.

[0078] In this embodiment of the application, when the vehicle's steering wheel or driver's seat vibrates, the vehicle's dashboard can display the text content corresponding to the first reminder information, and the vehicle's audio equipment can play the voice content corresponding to the first reminder information.

[0079] Optionally, if at least one of the engine fuel tank level and vehicle speed information does not meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message is sent through a mobile device bound to the vehicle (such as a mobile phone connected to the vehicle via Bluetooth). The first reminder message is used to remind the user to actively start the engine to perform engine maintenance.

[0080] For example, if the fuel level in the vehicle's engine tank does not meet the specified conditions, but the total mileage information meets the specified conditions, the vehicle control unit can send the text message "Engine fuel level is low, please add fuel!" to the mobile device currently bound to the vehicle to remind the user to add engine fuel.

[0081] For example, if the current vehicle speed does not meet the specified speed, but the total mileage information meets the specified conditions, the vehicle control unit can send the text content corresponding to the first reminder message "Current speed is too low, please accelerate!" to the mobile device currently bound to the vehicle, so as to remind the user to accelerate and make the current speed meet the specified conditions.

[0082] Optionally, if at least one of the engine fuel tank level and vehicle speed information does not meet the corresponding specified conditions, but the total mileage information meets the corresponding specified conditions, a first reminder message is issued through the color of the vehicle's interior lights. The first reminder message is used to remind the user to actively start the engine to perform engine maintenance.

[0083] For example, if the engine fuel tank level is below a specified level, but the total mileage meets the specified conditions, the interior lights will turn red to remind the user to add fuel to the engine and bring the engine fuel tank level to the specified level. The lights will then turn off once the engine fuel tank level meets the specified conditions.

[0084] For example, if the current vehicle speed does not meet the specified speed, but the total mileage information meets the specified conditions, the lights inside the vehicle will turn green to remind the user to accelerate so that the current speed meets the specified conditions. The lights will turn off after the speed meets the specified conditions.

[0085] In this embodiment of the application, when the interior lights of the vehicle are turned on, the vehicle's dashboard can display the text content corresponding to the first reminder information, and the vehicle's audio equipment can play the voice content corresponding to the first reminder information.

[0086] In this embodiment, when the total mileage of the vehicle meets the corresponding specified conditions, if a specified number of the other two conditions (engine fuel tank level and vehicle speed information) used to control the hybrid vehicle to enter the self-maintenance mode do not meet the corresponding specified conditions, the vehicle control unit can display a first reminder message to the user through the instrument panel to remind the user to actively start the engine. After receiving the first reminder message, the user can perform the specified operation according to the specific content of the first reminder message to actively start the engine, which expands the engine starting method and further improves the efficiency of engine self-maintenance.

[0087] It should be noted that, in the embodiments of this application, the above-mentioned vehicle is a hybrid vehicle as an example. Hybrid vehicles are not limited to traditional hybrid electric vehicles (HEVs), but also include plug-in hybrid electric vehicles (PHEVs) and range-extended hybrid electric vehicles, etc.

[0088] In this embodiment, when the vehicle's engine is not started and the time difference between the last engine start time and the current time meets a specified duration, the vehicle control unit can obtain information on the engine fuel tank level, the vehicle's total mileage, and the vehicle speed. If all three conditions are met, the vehicle's engine is started, putting the engine into self-maintenance mode. After starting, the internal parts of the engine operate, which enhances the flow of lubricating oil, thereby fully lubricating the internal parts and achieving the effect of engine maintenance. Furthermore, when the engine coolant temperature reaches a specified temperature, the engine is controlled to exit self-maintenance mode to avoid unnecessary power consumption. Additionally, if the engine fuel tank level and vehicle speed are both within a specified time range, the vehicle control unit can obtain information on the engine fuel tank level, total mileage, and vehicle speed. If at least one of the speed information does not meet the corresponding specified condition, but the total mileage information meets the corresponding specified condition, then the first reminder information is displayed on the vehicle's instrument panel. This effectively reminds the user to actively start the engine, thereby ensuring that the vehicle's engine can be maintained in a timely manner. In the above solution, the vehicle control unit can actively control the vehicle's engine to enter / exit the self-maintenance mode, and can also prompt the user to actively start the engine. In the engine self-maintenance scenario, it provides two engine starting methods: automatic engine starting and prompting the user to manually start the engine. This improves the engine starting efficiency in the engine self-maintenance scenario and can effectively achieve the engine maintenance effect.

[0089] Based on the solutions shown in the above embodiments, in some embodiments, the specified conditions corresponding to the fuel tank level of the vehicle's engine include: the fuel tank level of the vehicle's engine is higher than a specified level.

[0090] For example, the specified liquid level height can indicate that once the fuel in the vehicle's engine fuel tank reaches this height, the fuel in the engine fuel tank can support the engine's start-up and operation for a specified duration.

[0091] Based on Figure 2, the above solution also includes step 250. Please refer to Figure 3, which is a flowchart of an engine starting method provided in an embodiment of this application. Details are as follows:

[0092] Step 250: If the fuel level in the vehicle's engine fuel tank is not higher than the specified level, a second reminder message will be displayed on the vehicle's instrument panel. The second reminder message is used to remind the user to add fuel so that the engine can enter the self-maintenance mode normally.

[0093] In this embodiment of the application, the second reminder message for reminding the user to refuel is not limited to being displayed on the vehicle's dashboard. It can also be sent to the user through at least one of the following methods: voice broadcast, vibration of the vehicle's steering wheel or driver's seat, color of the vehicle's interior lights, or a mobile device bound to the vehicle (such as a mobile phone connected to the vehicle via Bluetooth).

[0094] The second reminder message may include a specified fuel level, allowing users to clearly understand the target amount of fuel to be added and to refuel efficiently.

[0095] For example, if the engine fuel tank level is 3% and the target fuel level is 10%, the second reminder message could be the text "Current engine fuel tank level is 3%, target level is 10%, fuel is low, please add fuel!"

[0096] In this embodiment, when the amount of fuel in the engine is insufficient to support engine startup and continuous operation for a specified duration, the vehicle control unit can issue a second reminder message through the instrument panel to remind the user to add fuel. This allows the user to quickly understand the current fuel level of the vehicle and replenish fuel in a timely manner, enabling the vehicle to reach the conditions for entering self-maintenance mode as soon as possible, improving engine starting efficiency, and thus effectively ensuring the maintenance effect of the engine.

[0097] Based on the solutions shown in the above embodiments, in some embodiments, the vehicle control unit internally includes a self-maintenance flag signal bit, the self-maintenance flag signal in the self-maintenance flag signal bit is used to indicate whether the vehicle's engine enters or exits the self-maintenance condition; the vehicle control unit in the hybrid vehicle displays self-maintenance condition prompt information on the vehicle's instrument panel according to the self-maintenance flag signal; the self-maintenance condition prompt information includes a first prompt information or a second prompt information; the first prompt information is used to indicate whether the engine enters the self-maintenance condition; the second prompt information is used to indicate whether the engine exits the self-maintenance condition.

[0098] In this embodiment, the vehicle control unit includes a self-maintenance flag signal bit for monitoring the engine status. The self-maintenance flag signal bit is a binary signal bit that can be set to "0" or "1" to indicate whether the engine is currently in or out of self-maintenance mode. For example, "0" can indicate that the engine has exited self-maintenance mode or is not in self-maintenance mode, while "1" can indicate that the engine has entered self-maintenance mode or is currently in self-maintenance mode. Conversely, "1" can indicate that the engine has exited self-maintenance mode or is not in self-maintenance mode, while "0" can indicate that the engine has entered self-maintenance mode or is currently in self-maintenance mode.

[0099] The vehicle control unit determines the specific prompt information (first prompt information or second prompt information) corresponding to the self-maintenance condition prompt information based on the information indicated by the self-maintenance indicator. After determining the specific prompt information corresponding to the self-maintenance condition prompt information, the first prompt information or the second prompt information is displayed on the vehicle's instrument panel to indicate whether the engine is currently in or out of self-maintenance condition.

[0100] In this embodiment of the application, the self-maintenance condition prompt information used to indicate whether the engine enters or exits the self-maintenance condition is not limited to being displayed on the vehicle's dashboard. It can also remind the user through at least one of the following methods: voice broadcast, vibration intensity of the vehicle's steering wheel or driver's seat, color of the vehicle's interior lights, or a mobile device bound to the vehicle (such as a mobile phone connected to the vehicle via Bluetooth).

[0101] In this embodiment of the application, the vehicle's instrument panel can promptly obtain the status of the engine entering or exiting the self-maintenance mode by using the self-maintenance flag signal indicated by the self-maintenance flag signal bit, and display it on the instrument panel so that the user can quickly understand the current status of the engine.

[0102] Based on the solutions shown in the above embodiments, in some embodiments, before the vehicle control unit in the hybrid vehicle displays the self-maintenance status prompt information on the vehicle's instrument panel according to the self-maintenance flag signal, the vehicle control unit in the hybrid vehicle controls the self-maintenance flag signal to be set to 1 when the engine enters the self-maintenance status, so that the vehicle's instrument panel displays the first prompt information; when the engine exits the self-maintenance status, it controls the self-maintenance flag signal to be set to 0, so that the vehicle's instrument panel displays the second prompt information.

[0103] In this embodiment, the vehicle control unit can detect the engine status through various sensors. After detecting that the engine has automatically started and entered self-maintenance mode, it controls the binary signal bit in the self-maintenance flag signal bit to change to "1" and sends a command to the vehicle's instrument panel to display a first prompt message indicating that the engine has entered self-maintenance mode. When detecting that the engine has exited self-maintenance mode, it controls the binary signal bit in the self-maintenance flag signal bit to change to "0" and sends a command to the vehicle's instrument panel to display a second prompt message indicating that the engine has exited self-maintenance mode.

[0104] In this embodiment of the application, the vehicle's dashboard displays a first or second prompt message corresponding to the signal on the self-maintenance flag signal position, enabling the user to understand the current engine status more quickly.

[0105] Based on the solutions shown in the above embodiments, in some embodiments, when the engine enters the self-maintenance mode, the vehicle control unit in the hybrid vehicle controls the self-maintenance flag signal to be set to 1; sends the self-maintenance flag signal to the vehicle's CAN network, so that the vehicle's instrument panel control unit receives the self-maintenance flag signal through the CAN network and displays the first prompt information on the vehicle's instrument panel according to the self-maintenance signal.

[0106] In this embodiment, after the engine enters the self-maintenance mode, the vehicle control unit controls the self-maintenance flag signal to be set to 1, indicating that the engine has entered the self-maintenance state. Then, the self-maintenance flag signal 1 is encapsulated into a CAN message and sent to the vehicle's instrument panel via the CAN network. After receiving the CAN message, the instrument panel parses the CAN message, obtains the self-maintenance flag signal 1 in the CAN message, and searches for the first prompt information that matches the self-maintenance flag signal 1 in the database of the vehicle control unit, and displays it.

[0107] In this embodiment of the application, the vehicle's dashboard can display a first prompt message based on the self-maintenance indicator signal 1, enabling the user to quickly understand that the engine has entered the self-maintenance condition and improving the efficiency of engine maintenance.

[0108] Based on the solutions shown in the above embodiments, in some embodiments, when the engine exits the self-maintenance mode, the vehicle control unit in the hybrid vehicle controls the self-maintenance flag signal to be set to 0; and sends the self-maintenance flag signal to the vehicle's CAN network, so that the vehicle's instrument panel control unit can receive the self-maintenance flag signal through the CAN network and display a second prompt message on the vehicle's instrument panel according to the self-maintenance signal.

[0109] In this embodiment, after the engine exits the self-maintenance mode, the vehicle control unit controls the self-maintenance flag signal to be set to 0, and then encapsulates the self-maintenance flag signal 0 into a CAN message and sends it to the vehicle's instrument panel via the CAN network. After receiving the CAN message, the instrument panel parses the CAN message, obtains the self-maintenance flag signal 0, and searches for a second prompt message that matches the self-maintenance flag signal 0 in the database corresponding to the vehicle control unit, and displays it.

[0110] In this embodiment of the application, the vehicle's dashboard can display a second prompt message based on the self-maintenance indicator signal, allowing the user to quickly understand that the engine has exited the self-maintenance mode, thereby improving the efficiency of engine maintenance.

[0111] Based on the steps in the embodiments of Figures 2 to 3 above, this application embodiment shows a self-maintenance strategy control method for hybrid vehicle engines.

[0112] This solution, by developing an engine self-maintenance function, can effectively avoid the lubrication risks associated with hybrid or range-extended vehicles due to prolonged engine inactivity.

[0113] This solution can extend the service life of a vehicle's engine and also improve software redundancy.

[0114] Regarding the engine self-maintenance function, this solution mainly calculates based on GPS time, engine coolant temperature, vehicle door and hood status, mileage, and vehicle speed. In addition, considering the vehicle's sleep mode, a sleep memory function has been specifically developed to prevent the engine from being accidentally started. If the driver's vehicle battery has a high charge (default 30%), the vehicle will automatically return to EV mode after the self-maintenance is completed.

[0115] I. Time Calculation

[0116] The vehicle controller first reads the current real-time date information from the GPS signal received by the vehicle, and then outputs the current time as the first time into the memory, that is, it is saved as the historical time in the above embodiment. After the vehicle is locked and put into sleep mode, the memory value (historical time) will be solidified in the hardware. If the engine is started, the date (year, month, day) of this start will be re-output as a new memory value to overwrite the previous memory value, and it will be saved after the vehicle is locked and put into sleep mode.

[0117] II. Start-up Time Difference Calculation

[0118] After the engine starts successfully, the current start time is stored as a memory value in the NVM area of ​​the controller. Each time the vehicle is driven by the electric motor and the engine is not started, the corresponding date will be compared with the date stored in the NVM area, i.e., the time difference. If the time difference meets the preset value, the conditions for engine start are met.

[0119] III. Self-maintenance activation and deactivation

[0120] Once the time difference condition is met, the controller will issue a set condition. To avoid triggering by some infrequent operating conditions, some restrictions have been added, as follows:

[0121] 1. The fuel level in the engine fuel tank must be above a certain limit.

[0122] 2. The mileage must be greater than the set value.

[0123] 3. The vehicle speed exceeds the required value.

[0124] Once all three conditions are met, the self-maintenance mechanism will be activated, the engine starting condition will be set, and the engine will automatically ignite and start according to the set condition. At the same time, the vehicle's instrument panel will also display the HEV mode, allowing the internal parts of the engine to be fully lubricated.

[0125] To avoid ineffective lubrication, the engine will automatically exit self-maintenance mode and complete one maintenance cycle once the engine coolant temperature reaches the set value.

[0126] IV. Restore to EV mode

[0127] After the engine self-maintenance conditions are completed, the self-maintenance conditions are set to 0, and the engine start conditions are also set to 0. If the vehicle's power battery charge is greater than 30% at this time, the instrument panel will automatically switch back to EV mode due to the change in start conditions.

[0128] V. Time Memory

[0129] The time after the engine starts will be temporarily stored in the NVM area as a new time. After the user locks the car, the start time temporarily stored in the NVM area will be kept in the NVM area until the engine is started again.

[0130] Through the above approach, the engine self-maintenance strategy has undergone multi-sample, multi-redundancy testing, ensuring that there will be no accidental engine start-up. Drivers can enjoy the power and quietness of a hybrid vehicle without worrying about engine stability.

[0131] Please refer to Figure 4, which is a schematic diagram of engine self-maintenance entry and exit provided in an embodiment of this application. As shown in Figure 4, the line segment corresponding to "Preparation" indicates that the vehicle is fully connected to high voltage and has the ability to drive. Here, high voltage means that the current vehicle voltage is sufficient to support the vehicle's ability to be driven by the electric motor alone, which can be 330V-360V; the line segment corresponding to "Fuel Level" indicates the fuel level in the vehicle's fuel tank; the line segment corresponding to "Vehicle Speed" indicates the vehicle's driving speed, calculated by ESP (Electronic Stability Program); the line segment corresponding to "Engine Coolant Temperature" indicates the engine coolant temperature; "Current Time" indicates the current GPS time obtained by the vehicle controller through the CAN network; "Memory Time" indicates the date of the last engine start, recorded in the controller's NVM; the line segment corresponding to "Self-Maintenance Flag" indicates a binary flag bit sent by the vehicle controller to the CAN network when the self-maintenance conditions are met. 0 indicates invalid, i.e., the self-maintenance conditions are not met; 1 indicates valid, i.e., the self-maintenance conditions are met.

[0132] In this embodiment, the hybrid vehicle is powered on normally, ensuring the vehicle enters a ready state. After the vehicle is powered on and enters the ready state, the controller obtains the current time and the memory time (i.e., the engine's last start time), calculates the difference, and determines whether the time difference meets the conditions. During this process, the driver drives normally and safely. After the vehicle speed exceeds the preset value, the fuel tank level meets the conditions, and the mileage reaches the required level, the engine is started. After the engine starts, the engine self-maintenance flag is set to 1, and signal 1 is sent to the CAN network. The CAN network sends this signal to the vehicle's instrument panel. After receiving the signal, the instrument panel displays a prompt message on the screen: "Engine self-maintenance in progress." After the engine starts, once the engine coolant temperature meets the preset value, the self-maintenance condition is exited, and the self-maintenance flag is set to 0. After the instrument panel receives the engine self-maintenance signal and sets it to 0, the prompt message on the screen is not displayed.

[0133] In this embodiment of the application, in order to avoid problems or risks caused by the engine not starting for a long time, the above solution makes an initial setting in the software to force the engine to start once when the driver's driving environment meets the conditions, so as to protect the internal parts of the engine and extend the service life of the engine.
