Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a control method, system and device of a vehicle range extender, and a readable storage medium. BACKGROUND

[0002] A range-extended electric vehicle (REEV) is a special type of electric vehicle, which is mainly characterized by being equipped with a range extender for charging the battery pack when the battery power is insufficient, thereby extending the cruising range of the vehicle. Compared with traditional electric vehicles, the range-extended electric vehicle solves the problems of limited cruising range and insufficient charging facilities of electric vehicles through this way, and improves the practicality and flexibility of electric vehicles.

[0003] In related technologies, the starting condition of the range extender is usually set by timing or based on a single parameter (such as the remaining power of the vehicle). This way has the following problems: according to the existing control mechanism, the range extender will start at a fixed time, the user cannot know when to start, and cannot actively choose the appropriate time, resulting in a lack of personalization and rationality in the control of the range extender; secondly, the range extender may start directly when the temperature is too low, which is easy to cause parts wear; finally, some existing systems only rely on single parameters such as altitude or environmental temperature in different regions to adjust the temperature threshold, resulting in inaccurate temperature threshold setting, which cannot be used in complex and variable actual environments, resulting in the range extender starting under non-ideal conditions, and thus affecting the system life and operating efficiency. SUMMARY

[0004] The present application mainly provides a control method, system and device of a vehicle range extender, and a readable storage medium. The technical solution of the present application is as follows:

[0005] In a first aspect, a control method of a vehicle range extender is provided, the method comprising: determining a target starting time and a target working mode of the range extender according to personalized data of a user; determining a dynamic temperature threshold for starting the range extender based on a multi-dimensional parameter dynamic temperature threshold calculation model according to environmental information of an environment in which the vehicle is located; when the temperature of the range extender is less than the dynamic temperature threshold, performing temperature control on the range extender to make the temperature of the range extender reach the dynamic temperature threshold; when the temperature of the range extender is greater than or equal to the dynamic temperature threshold, controlling the range extender to start and work in the target working mode when the target starting time is reached; wherein the personalized data includes at least one of historical starting habits of the user, real-time driving route of the vehicle, and real-time weather data.

[0006] According to the above technical means, the target starting time and the working mode of the range extender are determined through the personalized data of the user, so that the personalization and adaptability of the starting strategy are improved. In combination with the environmental information, the multi-dimensional parameter dynamic temperature threshold calculation model is used, and factors such as the environmental temperature, humidity, atmospheric pressure and historical operation data are comprehensively considered to dynamically adjust the temperature threshold of the starting of the range extender. Compared with the way of setting the temperature threshold by relying on only a single parameter in the prior art, the way is more scientific and reasonable. When the temperature of the range extender does not reach the dynamic temperature threshold, heating treatment is performed first, so as to avoid the component wear caused by direct starting in the low-temperature state, thereby effectively prolonging the service life of the equipment and improving the safety and reliability of the system operation.

[0007] In some embodiments, the determining the target starting time and the target working mode of the range extender further includes: generating a range extender starting recommendation scheme based on the user personalized data, the recommendation scheme including a recommended starting time and a recommended working mode of the range extender; showing the range extender starting recommendation scheme to the user; in the case that the user accepts the recommendation scheme, determining the recommended starting time as the target starting time and the recommended working mode as the target working mode; in the case that the user does not accept the recommendation scheme, using a user-inputted customized starting time and a customized working mode as the target starting time and the target working mode.

[0008] According to the above technical means, the starting recommendation scheme is generated based on the user personalized data and is shown to the user, so that the user can flexibly choose whether to accept the recommendation scheme according to the own demand. If the user accepts, the intelligent recommended starting time and working mode are adopted, so that the intelligent degree of the vehicle and the user experience are enhanced. If the user does not accept, the user is allowed to customize the starting time and the working mode, so that the diversified use scenarios of different users can be met.

[0009] In some embodiments, the vehicle includes a temperature control unit, and the temperature control on the range extender to make the temperature of the range extender reach the dynamic temperature threshold includes: heating the range extender by using the temperature control unit; determining an expected heating duration according to the difference between the temperature of the range extender and the dynamic temperature threshold and the temperature rise rate of the temperature control unit; showing the remaining heating duration to the user according to the expected heating duration and the current time; and controlling the temperature control unit to stop heating in the case that the temperature of the range extender reaches the dynamic temperature threshold.

[0010] According to the above technical means, the range extender is heated by the temperature control unit, and the required heating time is accurately calculated according to the difference between the current temperature and the target temperature and the temperature rise rate, so as to realize fine control of the heating process. At the same time, the remaining heating time is fed back to the user, so that he can know the start preparation in advance and improve the use experience. When the temperature reaches the standard, the heating is automatically stopped to prevent overheating damage to the equipment and further protect the safety and stability of the system operation.

[0011] In some embodiments, the method further comprises: in the case that the temperature of the range extender is greater than the safety temperature threshold, controlling the range extender to remain in the shutdown state, and sending an over-temperature warning information to the user, the over-temperature warning information being used to prompt the user that the temperature of the range extender is too high.

[0012] According to the above technical means, when the temperature of the range extender exceeds the safety range, its start is prohibited, and warning information is sent to the user in time to prevent abnormal operation of the equipment in a high-temperature environment and ensure good self-protection ability. The push of the warning information also helps the user to take measures in time, such as checking the equipment state or contacting the maintenance service, thereby further improving the system safety.

[0013] In some embodiments, the method further comprises: during the operation of the range extender, controlling the operating temperature of the range extender by the temperature control unit to keep the operating temperature of the range extender stable; wherein the operating temperature of the range extender is greater than or equal to the dynamic temperature threshold and less than the safety temperature threshold.

[0014] According to the above technical means, after the range extender starts, its operating temperature is regulated by the temperature control unit to maintain between the dynamic temperature threshold and the safety temperature threshold, so as to avoid affecting the performance or causing damage to the equipment due to excessive temperature fluctuation. This closed-loop control method helps to improve the stability and efficiency of the vehicle range extension system operation, and also enhances its durability and reliability.

[0015] In some embodiments, before determining the target start time and the target working mode of the range extender according to the user's individualized data, the method further comprises: receiving a voice control instruction sent by a person in the vehicle, the voice instruction being used to instruct to start the range extender; verifying the voice control instruction and the voiceprint of the target user of the vehicle pre-recorded; in the case that it is determined that the voice control instruction is the control instruction sent by the target user, determining the target start time and the target working mode according to the individualized data.

[0016] According to the above technical means, based on the voice control function and combined with the voiceprint recognition technology, it is ensured that only the authorized user can operate the range extender to start, and misoperation is effectively prevented. Meanwhile, the voice control is combined with the personalized data to realize a more natural and convenient human-computer interaction mode, and the usability and safety of the control method are improved.

[0017] In some embodiments, the environmental information includes at least one of the following: ambient temperature, humidity, atmospheric pressure, and historical operation data of the vehicle.

[0018] According to the above technical means, by introducing multiple parameters such as ambient temperature, humidity, and atmospheric pressure, a more scientific and reasonable dynamic temperature threshold calculation model is constructed, which can more accurately evaluate the influence of the current environment on the start of the range extender and improve the safety and reliability of the start of the range extender.

[0030] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application

[0031] In the following description, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subset of all possible embodiments, and can be combined with each other without conflict.

[0032] In the following description, the terms "first\second\third" are only used to distinguish different objects, and do not represent a specific order of the objects, and do not have a limitation of sequence. It can be understood that "first\second\third" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application, and are not intended to limit the present application.

[0034] Range-Extended Electric Vehicle (REEV) is a special type of electric vehicle, which is mainly characterized by being equipped with a range extender for charging the battery pack when the battery power is insufficient, thereby extending the cruising range of the vehicle. Compared with traditional electric vehicles, REEV solves the problem of limited cruising range and insufficient charging facilities of electric vehicles through this way, and improves the practicality and flexibility of electric vehicles.

[0035] In the normal driving process, the REEV mainly relies on the electric energy in the battery pack to drive the electric motor to realize pure electric driving; when the battery power is low to a certain threshold, the range extender will start to drive the generator to generate power to charge the battery pack or directly power the electric motor, thereby extending the cruising ability of the vehicle.

[0036] In the related art, the starting condition of the range extender is usually set by timing or based on a single parameter (such as the remaining power of the vehicle). The problem of this way is: according to the existing control mechanism, the range extender will start regularly, and the user cannot know when to start (it may be in the morning at-20℃ or in the afternoon at 40℃), nor can the user actively choose the appropriate time, so that the control of the range extender lacks individualization and rationality. Secondly, the range extender may start directly when the temperature is too low, which is easy to cause parts wear. Finally, some existing systems only rely on a single parameter such as altitude or environmental temperature in different regions to adjust the temperature threshold, resulting in inaccurate temperature threshold setting, which cannot be used in complex and variable actual environment, resulting in the range extender starting under non-ideal conditions, thereby affecting the system life and operating efficiency.

[0037] To solve the problems of unreasonable starting time, lack of temperature protection mechanism and poor user interaction experience in the existing vehicle range extender control method, the present application provides an intelligent control method based on user individualization data and environmental information. The intelligent and individualized recommendation and accurate control of the starting time and working mode of the range extender are realized, thereby effectively improving the system operating efficiency, prolonging the service life of the equipment, and significantly improving the user experience.

[0038] In view of the above problems, the present application provides a vehicle range extender control method and device, an electronic device and a readable storage medium. The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Figure 1 is a schematic flowchart of the vehicle range extender control method provided by the present application, Figure 1 The method in comprises steps S110-S140.

[0040] In step S110, the target starting time and the target working mode of the range extender are determined according to the user's individualization data.

[0041] In the embodiments of the present application, the personalized data can be non-universal data such as driving behavior, driving route preference, and weather response characteristics related to a specific user. The personalized data can be at least one of historical starting habits of the user, real-time driving route of the vehicle, and real-time weather data. For example, the user can tend to start early during the rush hour to avoid running out of power; or, according to the driving route of the vehicle, when the distance to the charging pile at the destination is short, the user will tend to stop the range extender to reduce fuel consumption; or, in low-temperature weather, the user will tend to start the range extender early to heat the air in the vehicle through the residual heat generated by the operation of the range extender to ensure the comfort of driving.

[0042] The target starting time is the optimal starting time recommended according to the personalized data. For example, in a low-temperature environment, the vehicle range extender control system will recommend that the user start the range extender when the remaining power is greater than 40% so as to have enough time to complete the heating process; for example, when it is determined according to the driving route that the vehicle is far from the destination, the range extender control system will recommend that the user start the range extender early to avoid the situation of battery power shortage.

[0043] The target working mode refers to the working mode of the range extender after starting, which can include different working speeds, different output powers, etc. of the range extender. Different working modes can be suitable for different scenarios. For example, in cold weather, the range extender is controlled to work in a low-speed mode at the initial stage of starting; for example, in the case of low current power of the vehicle, the range extender is controlled to work in a high-speed mode to improve the power generation.

[0044] In step S120, a dynamic temperature threshold value for starting the range extender is determined based on the environmental information of the vehicle environment and a multi-dimensional parameter dynamic temperature threshold value calculation model.

[0045] In the embodiments of the present application, the environmental information includes but is not limited to parameters such as environmental temperature, humidity, and atmospheric pressure. The above-mentioned multiple parameters directly affect the starting performance and safety of the range extender. For example, in a high-humidity environment, the starting process of the range extender has great difficulty, so the environmental temperature needs to be increased to ensure normal starting; in the plateau area, due to the low atmospheric pressure, the combustion efficiency of the range extender is low, so the temperature threshold value needs to be appropriately increased.

[0046] The multi-dimensional parameter dynamic temperature threshold calculation model is a mathematical model that can comprehensively consider various environmental factors and dynamically adjust the temperature required for the range extender to start. The multi-dimensional parameter dynamic temperature threshold calculation model takes environmental temperature, humidity, atmospheric pressure and other data as input variables, and outputs a dynamically changing temperature threshold through a pre-set algorithm and model parameters. In the case of high humidity, the vehicle range extender control system will automatically increase the dynamic temperature threshold to ensure that the range extender can start in the best state; in low-altitude areas, the vehicle range extender control system can optimize the dynamic temperature setting according to historical operation data to improve energy efficiency.

[0047] In step S130, when the temperature of the range extender is less than the dynamic temperature threshold, the temperature of the range extender is controlled to reach the dynamic temperature threshold.

[0048] In specific implementation, when the range extender temperature is detected to be lower than the dynamically calculated dynamic temperature threshold, the vehicle range extender control system will automatically start the temperature control device until the temperature meets the standard. The temperature control device may, for example, include a PTC ceramic heating sheet, which has the advantages of fast temperature rise, low energy consumption, high safety, etc. For example, in an extremely cold environment of-30℃, the vehicle range extender control system will start the heating function according to the dynamic temperature threshold to raise the temperature of the range extender above the dynamic temperature threshold.

[0049] The vehicle range extender control system will accurately calculate the heating time according to the difference between the current temperature and the target temperature, and control the heating device to operate at appropriate power. At the same time, the vehicle range extender control system will also continuously monitor the temperature change of the range extender to ensure that the range extender operates within a safe range. This way not only improves the starting efficiency, but also helps to prolong the service life of the equipment.

[0050] In step S140, when the temperature of the range extender is greater than or equal to the dynamic temperature threshold, the range extender is controlled to start and work in the target working mode when the target starting opportunity is reached.

[0051] When the range extender temperature reaches or exceeds the dynamically calculated dynamic temperature threshold and the target starting opportunity is reached, the vehicle range extender control system will start the range extender according to the target working mode. For example, in the case of user acceptance of the pre-heating mode, the vehicle range extender control system will complete the heating within a pre-set time and start the range extender after confirming that the temperature meets the standard, to ensure that the range extender operates in the best state.

[0052] According to the above technical means, the target starting time and working mode of the range extender are determined through the personalized data of the user, so that the personalization and adaptability of the starting strategy are improved. In combination with environmental information, the temperature threshold of the range extender starting is dynamically adjusted by using a multi-dimensional parameter dynamic temperature threshold calculation model, which is more scientific and reasonable than the way of setting the temperature threshold by relying on only a single parameter in the prior art. Further, when the temperature of the range extender does not reach the dynamic temperature threshold, heating treatment is performed first, so as to avoid component wear caused by direct starting in a low-temperature state, thereby effectively prolonging the service life of the equipment and improving the safety and reliability of system operation.

[0053] In some embodiments, with reference to Figure 2 The foregoing step S110 of determining the target starting time and target working mode of the range extender based on the personalized data of the user further includes steps S111-S114.

[0054] In step S111, a range extender starting recommendation scheme is generated based on the personalized data, and the recommendation scheme includes a recommended starting time and a recommended working mode of the range extender.

[0055] The personalized data of the user refers to a set of data collected and analyzed by the system in relation to the user's use habits, behavior preferences and vehicle operating environment. Through intelligent analysis of the personalized data of the user, the user's starting preferences in different scenarios can be identified, such as whether the user tends to start the range extender when the battery is low, whether the user often travels at a certain time period, etc.

[0056] In step S112, the range extender starting recommendation scheme is presented to the user.

[0057] The way of presenting the range extender starting recommendation scheme includes two main forms of voice prompts and mobile phone application program interface displays.

[0058] The voice prompt mode can be played through the vehicle-mounted voice system to inform the user of the recommended starting time and mode, and at the same time, the voiceprint binding technology can be used to ensure that only authorized users can receive the relevant instructions.

[0059] The mobile phone APP provides a more intuitive graphical interface, and the user can see detailed recommendations on the screen, such as the estimated starting time, the recommended working mode, and the basis for the recommended working mode, etc.

[0060] In step S113, in the case where the user accepts the range extender starting recommendation scheme, the recommended starting time is determined as the target starting time, and the recommended working mode is determined as the target working mode.

[0061] When the user chooses to accept the range extender starting recommendation scheme recommended by the system, the system will automatically set the recommended starting time and working mode as the final execution parameters.

[0062] In step S114, in the case that the user does not accept the recommended scheme, the actual and target working modes are started with the user-inputted customized starting time and customized working mode as the target.

[0063] If the user rejects the range extender starting recommendation scheme recommended by the system, the user can select to manually input the customized starting time and working mode. At this time, the system will no longer rely on the recommendation logic, but will operate according to the parameters set by the user. The way in which the user selects to manually input the customized starting time and working mode gives the user higher control, and the user can flexibly adjust the starting strategy of the range extender in special situations.

[0064] According to the above technical means, the starting recommendation scheme is generated based on the user personalized data and is displayed to the user, so that the user can flexibly select whether to accept the recommended scheme according to the user's own needs. If the user accepts, the intelligent recommended starting time and working mode are adopted, which enhances the intelligent degree of the system and the user experience; if the user does not accept, the user is allowed to customize the starting time and working mode, which improves the controllability and flexibility of the system and meets the diversified use scenarios of different users.

[0065] In some embodiments, the vehicle further comprises a temperature control unit. Referring to Figure 3 , the aforementioned step S130, the temperature control unit is used to control the temperature of the range extender so that the temperature of the range extender reaches the dynamic temperature threshold, and the step S130 further comprises steps S131-S134.

[0066] In step S131, the temperature control unit is used to heat the range extender.

[0067] The temperature control unit refers to a device for controlling the temperature of the range extender of the vehicle, which includes heating and cooling functions. In this embodiment, when the temperature of the range extender does not reach the preset dynamic temperature threshold, the temperature control unit starts the PTC ceramic heating sheet to heat the core components of the range extender.

[0068] In actual application, when the system detects that the temperature of the range extender is lower than the dynamic temperature threshold, the intelligent control center will automatically activate the heating module in the temperature control unit to heat the range extender, so that the engine will not be directly started due to low temperature, reducing the mechanical wear of the engine and prolonging the service life of the engine.

[0069] In step S132, the expected heating duration is determined according to the difference between the temperature of the range extender and the dynamic temperature threshold, and the temperature rise rate of the temperature control unit.

[0070] The predicted heating duration is a time prediction value calculated by calculating the temperature difference between the current temperature of the range extender and the target temperature (i.e., the dynamic temperature threshold) and combining the temperature rise rate of the temperature control unit. For example, if the current temperature of the range extender is -5°C, the dynamic temperature threshold is 10°C, and the average temperature rise rate of the temperature control unit is 2.5°C / min, the predicted heating duration is about 6 minutes.

[0071] At step S133, the remaining heating duration is displayed to the user according to the preset heating duration and the current time.

[0072] In this embodiment, the system subtracts the calculated predicted heating duration from the current time to obtain the remaining heating time, and informs the user through voice broadcast or mobile phone APP push. For example, after the system detects that the temperature of the range extender is lower than the dynamic temperature threshold, the user will receive a prompt message: heating, estimated to be 3 minutes.

[0073] At step S134, the temperature control unit is controlled to stop heating when the temperature of the range extender reaches the dynamic temperature threshold.

[0074] When the temperature of the range extender reaches or exceeds the dynamic temperature threshold, the system will immediately control the temperature control unit to stop heating and enter a standby state. The process of heating the range extender and reaching the dynamic temperature threshold not only improves the response speed of the system, but also effectively avoids the problems of energy waste and equipment aging caused by excessive heating. In addition, the system will continue to monitor the temperature change of the range extender to ensure that the temperature of the range extender is stable within a safe range.

[0075] According to the above technical means, the range extender is heated by the temperature control unit, and the heating duration required is accurately calculated according to the difference between the current temperature and the target temperature and the temperature rise rate, so as to realize fine control of the heating process. At the same time, the remaining heating duration is fed back to the user, so that he can know the start preparation in advance and improve the use experience. When the temperature reaches the standard, the heating is automatically stopped to prevent overheating and damage the equipment, further ensuring the safety and stability of the system operation.

[0076] In some embodiments, the range extender control method further comprises: in the case that the temperature of the range extender is greater than the safety temperature threshold, controlling the range extender to remain in a shutdown state and sending an over-temperature warning message to the user.

[0077] The safety temperature threshold refers to the maximum operating temperature limit allowed by the range extender in the normal working state, which is usually dynamically calculated according to the engine material tolerance, historical operation data and environmental parameters. The safety temperature threshold is not fixed, but is dynamically calculated by a multi-dimensional parameter dynamic temperature threshold calculation model considering factors such as environmental temperature, humidity, atmospheric pressure, etc., to ensure that reasonable protection standards are provided under different working conditions.

[0078] The over-temperature early warning information is a feedback signal for prompting the user that the range extender temperature is abnormal. The form of the over-temperature early warning information can include voice broadcast, mobile phone APP pop-up window notification, instrument panel warning light and the like. The over-temperature early warning information not only informs the user that there is a risk at present, but also can be accompanied by specific operation suggestions, such as please turn off the range extender and wait for cooling or please contact the service center as soon as possible. The real-time feedback mechanism of the over-temperature early warning information enhances the user's sense of control over the system state and improves the transparency and safety in the use process.

[0079] When it is detected that the internal temperature of the range extender exceeds the set safety temperature threshold, the system will immediately stop the operation of the range extender to prevent damage or failure of the range extender components caused by high temperature. At the same time, the system pushes the over-temperature early warning information through the voice module or the mobile phone APP to remind the user that the current range extender is in an overheated state, and suggests checking the cooling system, waiting for cooling before trying to start again or contacting the maintenance personnel for processing. This mechanism effectively avoids damage to the equipment caused by continuous high-temperature operation and improves the stability and safety of the system.

[0080] According to the above technical means, when the temperature of the range extender exceeds the safety range, the system automatically prohibits the start of the range extender and sends early warning information to the user in time to prevent abnormal operation of the equipment in a high-temperature environment and ensure that the system has good self-protection ability. In addition, the push of the early warning information is also helpful for the user to take measures in time, such as checking the equipment state or contacting the repair service, thereby further improving the safety of the system.

[0081] In some embodiments, the method of controlling the range extender further comprises: during the operation of the range extender, controlling the operating temperature of the range extender by the temperature control unit to keep the operating temperature of the range extender stable; wherein the operating temperature of the range extender is greater than or equal to the dynamic temperature threshold and less than the safety temperature threshold.

[0082] As mentioned above, the temperature control unit refers to a hardware or software system for monitoring and adjusting the operating temperature of the range extender, which usually includes a temperature sensor, a heating / cooling device and an intelligent control module. The temperature control unit collects the temperature data of the key components (such as the engine cylinder and the cooling liquid pipeline) inside the range extender in real time and adjusts the temperature according to the preset control strategy to ensure that the range extender always operates in the best temperature range. For example, in a low-temperature environment, the temperature control unit can start the PTC ceramic heating sheet for heating; in a high-temperature environment, it can cool down through the forced air cooling system.

[0083] The dynamic temperature threshold refers to the upper limit of the temperature range calculated in real time according to multi-dimensional parameters (such as ambient temperature, humidity, atmospheric pressure, user historical operation data, etc.), which is used to determine whether the range extender is allowed to enter the normal working state. The dynamic temperature threshold is not fixed and will be dynamically adjusted by the system according to the current operating environment and user behavior habits. For example, in cold weather, the system sets a higher dynamic temperature threshold to ensure that the engine is fully preheated before starting; in a high-temperature environment, the system will appropriately lower the dynamic temperature threshold to avoid overheating damage.

[0084] The safety temperature threshold refers to the maximum temperature limit at which the range extender can still operate safely in extreme conditions. When the operating temperature of the range extender exceeds the safety temperature threshold, the control system will trigger a protection mechanism, suspend the operation of the range extender, and send a prompt message to the user, suggesting that the user check the equipment. The safety temperature threshold is usually set by engineers according to the hardware design limits and long-term operation experience, which has strong conservatism and safety.

[0085] Controlling the temperature of the range extender between the dynamic temperature threshold and the safety temperature threshold can ensure that the range extender will not be affected in performance due to low temperature, nor will it be damaged due to high temperature.

[0086] According to the above technical means, after the range extender starts, the system continuously regulates its operating temperature through the temperature control unit to maintain it between the dynamic temperature threshold and the safety temperature threshold, avoiding performance impact or equipment damage due to excessive temperature fluctuations. This closed-loop control method helps to improve the stability and efficiency of system operation, while also enhancing the durability and reliability of the equipment.

[0087] In some embodiments, referring to Figure 4 Before the foregoing step S110, the range extender control method further includes steps S410-S420.

[0088] In step S410, a voice control instruction sent by a person in the vehicle is received, and the voice control instruction is used to instruct to start the range extender.

[0089] The voice control instruction refers to the operation command issued by the user to the system through voice, such as starting the range extender. The vehicle-mounted voice recognition system can collect and analyze the voice control instruction and use it as an input signal for the vehicle-mounted control system to perform corresponding operations.

[0090] In step S420, the voice control instruction and the voiceprint of the target user pre-recorded are verified.

[0091] In the case where it is determined that the voice control instruction is a control instruction sent by the target user, the foregoing step S110 is performed.

[0092] In the embodiments of the present application, the target user can be the vehicle owner or other authorized users authorized by the owner. The voiceprint verification refers to comparing the voice control instruction with the voiceprint information of the owner or other authorized users pre-recorded to confirm whether the voice control instruction is issued by an authorized user after receiving the voice control instruction.

[0093] If the comparison result is a match, the voice control instruction is determined to be a legal instruction, and the subsequent operation process is executed. If the comparison result is a mismatch, the voice control instruction is determined to be an invalid instruction, and the instruction will not be responded. The process of voiceprint verification effectively prevents the situation of misoperation or malicious operation by unauthorized personnel, and enhances the security of the system.

[0094] According to the above technical means, the control method supports voice control function, and combines with voiceprint recognition technology to ensure that only authorized users can operate the range extender to start, effectively preventing misoperation. At the same time, the voice control is combined with personalized data to realize a more natural and convenient human-computer interaction mode, and the usability and security of the system are improved.

[0095] In some embodiments, the environmental information involved in the foregoing step S120 includes at least one of environmental temperature, humidity, and atmospheric pressure.

[0096] The environmental temperature refers to the current temperature value of the external space where the vehicle is located, which is usually obtained by a temperature sensor installed outside the vehicle. The environmental temperature directly affects the thermodynamic performance of the engine during cold start. For example, in a low-temperature environment, the viscosity of engine lubricating oil increases, resulting in increased starting resistance and easy wear of parts; while in a high-temperature environment, it may cause overheating risk.

[0097] Humidity represents the moisture content of the air in the environment where the vehicle is located, usually expressed in percentage. High humidity will reduce air density, affect combustion efficiency, and may cause internal condensation or condensation water accumulation in the engine, thereby increasing the difficulty of starting. Especially in cold and humid environments, ice may form on the surface of the engine cylinder, further exacerbating the cold start problem.

[0098] Atmospheric pressure reflects the atmospheric pressure level of the location where the vehicle is located, which is usually measured by an air pressure sensor installed outside the vehicle. Atmospheric pressure is closely related to altitude. In high-altitude areas, due to low air pressure, the oxygen concentration decreases, which will affect the combustion efficiency of the engine. Therefore, the system will dynamically adjust the starting strategy according to the change of atmospheric pressure to ensure safe and efficient starting operation under different altitude conditions.

[0099] According to the above technical means, by introducing multiple parameters such as ambient temperature, humidity and atmospheric pressure, a more scientific and reasonable dynamic temperature threshold calculation model is constructed, which can more accurately evaluate the influence of the current environment on the start of the range extender and improve the safety and reliability of the start of the range extender.

[0100] The technical solutions provided by the present application will be further described below in combination with examples.

[0101] The technical solutions provided by the embodiments of the present application aim to solve the following technical problems in the related art:

[0102] (1) The traditional range extender is automatically started like an alarm clock, and the user cannot know when to start (it may be in the early morning of minus 20 DEG C or in the afternoon of 40 DEG C high temperature), and the historical starting habits, driving routes and weather of the user are not considered, and the starting time lacks individualization and rationality.

[0103] (2) The engine may be directly started when the temperature is too low, like pouring cold water on a frozen person in winter, which causes parts to wear.

[0104] (3) The user can only wait for the system to automatically start, and cannot actively choose the appropriate time, nor can he plan to start in advance according to the driving route and weather.

[0105] (4) Some existing systems only rely on a single parameter of altitude in different regions to adjust the temperature threshold, and do not comprehensively consider multiple factors such as ambient temperature, humidity, atmospheric pressure and historical operation data, resulting in inaccurate temperature threshold setting and inability to adapt to complex and variable actual environment.

[0106] In view of the above technical problems, the present application provides a vehicle range extender control system 500, as shown in Figure 5 The control system 500 includes a voice control module 510, an intelligent recommendation module 520, a temperature sensing unit 530, an intelligent control center 540, a heating / cooling device 550 and a multi-dimensional parameter sensor group 560.

[0107] The voice control module 510 can be arranged on the steering wheel or center console of the vehicle, and is used to identify voice instructions. The voice instructions may be, for example, "start the range extender", "stop running" and the like.

[0108] In the technical solutions of the present application, the voice control module 510 can also respond to the voiceprint input by the owner or authorized user based on voiceprint binding technology, thereby preventing misoperation by others.

[0109] The intelligent recommendation module 520 includes: a historical starting habit recording unit for recording relevant information of each time the user starts the range extender, including battery power, time, weather, etc., and analyzing the user's historical starting habits based on these data. A driving route analysis unit for obtaining the user's driving route information, combining traffic conditions and historical data to analyze the impact of the driving route on the range extender start. A weather data acquisition unit for acquiring real-time weather data through the network, including temperature, humidity, wind speed, precipitation, etc., to provide reference for the starting strategy. A starting actual and mode recommendation algorithm for analyzing the best starting time and mode under different conditions according to the user's historical starting habits, driving route and weather data. For example, in cold weather and long driving route, the "pre-heating" mode is recommended; when the power is sufficient and the weather is good, the "delayed start" mode can be recommended.

[0110] The temperature sensing unit 530 can be provided in the engine cylinder or the cooling liquid pipeline, and its detection range can be, for example, -40℃-150℃, which covers the extreme environment of vehicle operation.

[0111] The intelligent control center 540 is deployed with a multi-dimensional parameter dynamic temperature threshold calculation model, which takes environmental temperature, humidity, atmospheric pressure, historical operation data, etc. as input, and dynamically calculates the temperature threshold of the range extender start through a preset algorithm and model parameters. For example, in a humid environment, the difficulty of engine start may increase, and the model will appropriately increase the temperature threshold; in the plateau area with low atmospheric pressure, the temperature threshold is adjusted comprehensively in combination with historical operation data and current atmospheric pressure.

[0112] The intelligent control center 540 is also used to allow starting when the engine temperature reaches the dynamically calculated temperature threshold in combination with the results of the multi-dimensional parameter dynamic temperature threshold calculation model. At the same time, according to the starting time and mode provided by the intelligent recommendation module, the user is advised, and if the user accepts, the corresponding starting operation is performed, so as to ensure that the engine starts in the appropriate temperature range and reduces wear and tear.

[0113] The heating / cooling device 550 is used to heat through PTC ceramic heating sheets at low temperature, and to cool through forced air cooling system at high temperature.

[0114] The multi-dimensional parameter sensor group 560 includes: a humidity sensor installed outside the vehicle for real-time detection of environmental humidity; an atmospheric pressure sensor installed outside the vehicle for measuring atmospheric pressure; a historical operation data storage unit for storing historical data such as past starting time, environmental parameters at starting time, and running time of the range extender, to provide data support for dynamic temperature threshold calculation.

[0115] Figure 6Schematic diagram of a flow chart of a range extender control method based on the above control system. Figure 6 The method includes steps S601-S618.

[0116] In step S601, it is determined whether the user's control mode is voice control, and if so, step S602 is executed.

[0117] In step S602, when the control mode is determined to be voice control, the voice control module receives a voice instruction input by the user. The voice instruction may be, for example, "start the range extender."

[0118] In step S603, the voice control module performs voiceprint verification on the received voice command. If the voiceprint verification passes, step S604 is executed; otherwise, the range extender is refused to start.

[0119] In step S604, temperature detection is started.

[0120] In step S605, the temperature of the range extender is detected by the temperature sensor unit, and the ambient humidity, ambient temperature, atmospheric pressure and other data are obtained through the multi-dimensional parameter sensor group, and the user's startup history habits, driving routes and weather data are obtained from the intelligent recommendation module.

[0121] In step S606, the intelligent control center inputs the acquired multi-dimensional parameters into a multi-dimensional parameter dynamic temperature threshold calculation model to calculate the dynamic temperature threshold for starting the range extender under the current circumstances.

[0122] In step S607, it is determined whether the range extender temperature meets the standard. If the range extender temperature meets the standard, step S608 is executed; otherwise, step S610 is executed.

[0123] In step S608 , the range extender is started.

[0124] In step S609, the startup status of the range extender is fed back to the user through voice broadcast and APP push.

[0125] In step S610 , when the temperature of the range extender does not meet the standard, the range extender is heated by using a heating / heat dissipation device.

[0126] In step S611, the heating time is calculated according to the range extender temperature, the dynamic temperature threshold and the temperature rise rate.

[0127] In step S612, the PTC ceramic heating plate of the heating / heating device is controlled to heat the range extender.

[0128] In step S613 , the temperature of the range extender is monitored in real time during the heating process to confirm whether the temperature of the range extender meets the standard.

[0129] According to the foregoing step S601, if the control mode is non-voice control, step S614 is executed to start intelligent recommendation.

[0130] In step S615, personalized data such as historical starting habits, implemented driving routes, and current weather are analyzed.

[0131] In step S616, a recommended scheme is generated.

[0132] In step S617, the recommended scheme is presented to the user, and it is determined whether the user accepts the recommended scheme. If the user accepts the recommended scheme, step S604 is executed. Otherwise, step S618 is executed.

[0133] In step S618, based on user input, the starting scheme (target starting time and target working mode) target starting time and target working mode are adjusted.

[0134] After the above adjustment is completed, step S604 is executed.

[0135] Compared with the prior art, the above technical solution provided by the present application has the following advantages:

[0136] The control method in the prior art is single, and the present application provides two ways of voice control and intelligent recommended starting, which can be actively selected by the user, and the intelligent recommendation is more personalized and reasonable.

[0137] The method can realize intelligent temperature control in a large range (such as -15℃-100℃), and introduces a multi-dimensional parameter dynamic temperature threshold calculation model, so that the temperature threshold setting is more scientific and reasonable.

[0138] The forced detection is performed before the range extender starts, and the starting condition is dynamically adjusted in combination with multi-dimensional parameters, considering user habits, driving routes, and weather, which avoids damage in low / high temperature and has higher safety.

[0139] The prior art lacks personalization and adaptability, and the method of the present application automatically recommends the starting time and mode according to user historical starting habits, driving routes, and weather data, which better adapts to different users and environments.

[0140] In order to verify the effectiveness of the technical solution of the present application, typical scene tests are performed:

[0141] In an extremely cold environment of -30℃, the system automatically adjusts the heating strategy according to a multi-dimensional parameter dynamic temperature threshold calculation model, comprehensively considers environmental humidity, atmospheric pressure, historical operation data, user historical starting habits, driving route and weather data and other factors, starts after the engine is heated to an appropriate temperature, can reduce engine wear by 80%, and prolongs the service life of the engine. At the same time, according to the user's driving route and weather conditions, the starting time is reasonably recommended to avoid starting too early at unnecessary times.

[0142] In a complex environment of high temperature and high humidity, abnormal atmospheric pressure, the system accurately judges through a multi-dimensional parameter dynamic temperature threshold calculation model, refuses to start the range extender at 110℃, and pushes a maintenance reminder to the service center, avoiding damage to the engine in high temperature, and improving the reliability of the system. And combined with the user's historical starting habits and driving route, the system provides subsequent starting suggestions for the user.
