Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an energy mode regulation method, device, vehicle, and storage medium. Background Technology

[0002] Currently, range-extended electric vehicles generally adopt rule-based energy management strategies. By preset battery SOC (State of Charge) thresholds, the vehicle's energy management mode is divided into operating modes such as "forced pure electric", "pure electric priority", "hybrid", and "fuel priority". At the human-machine interaction level, these modes are usually presented to users in the form of list menus with text descriptions for them to select manually.

[0003] The scheme has the following drawbacks: On the one hand, the strategic boundaries between different modes are blurred. For example, "forced pure electric" and "pure electric priority" have significant differences in economic performance and range, but the naming and descriptions are difficult to intuitively convey their usage scenarios and energy consumption characteristics. Similarly, "hybrid" and "fuel priority" have similar strategies in actual operation (such as mainly relying on the engine when cruising at high speeds), making it difficult for users to understand their functional differences. On the other hand, there is functional overlap in energy modes. For example, fuel priority and hybrid have similar strategies in high-speed scenarios, which increases the complexity of user choices and the risk of misoperation. Summary of the Invention

[0004] This application provides an energy mode adjustment method, device, vehicle, and storage medium to solve the problem that the boundaries of energy modes in related technologies are unclear, which leads to user confusion, resulting in a complex user experience and limited energy efficiency optimization.

[0010] Optionally, before identifying the energy mode selected by the user, the method further includes: obtaining the current charge level of the vehicle battery; if the current charge level is less than or equal to a first preset charge level, then locking the energy mode to the second energy mode.

[0011] Optionally, the target battery charge value is a preset value set according to different driving scenarios and / or a preset value set by the user, and the target battery charge value does not exceed a preset range.

[0012] A second aspect of this application provides an energy mode adjustment device, including an acquisition module for acquiring the current battery charge value of a vehicle and the energy mode selected by a user; a determination module for acquiring a second preset battery charge value and determining a target sub-energy mode of the vehicle based on the relationship between the current battery charge value and the first preset battery charge value when the user selects a first energy mode; acquiring a target battery charge value and a second preset battery charge value and determining the target sub-energy mode of the vehicle based on the relationship between the current battery charge value, the target battery charge value, and the second preset battery charge value when the user selects a second energy mode; and a control module for controlling the vehicle to drive according to the target sub-energy mode.

[0013] A third aspect of this application provides a vehicle, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the energy mode adjustment method of the first aspect.

[0014] A fourth aspect of this application provides a computer-readable storage medium having a computer program or instructions stored thereon, characterized in that, when the computer program or instructions are executed, they implement the energy mode regulation method of the first aspect.

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The energy mode adjustment method, apparatus, vehicle, and storage medium of this application are described below with reference to the accompanying drawings. Addressing the problems mentioned in the background art, such as unclear energy mode boundaries leading to user confusion, complex user experience, and limited energy efficiency optimization, this application provides an energy mode adjustment method. In this method, the current battery charge level of the vehicle and the energy mode selected by the user are obtained. When the user selects a first energy mode, a first preset charge level is obtained, and a target sub-energy mode of the vehicle is determined based on the relationship between the current charge level and the first preset charge level. When the user selects a second energy mode, a target battery charge level and a second preset charge level are obtained, and the target sub-energy mode of the vehicle is determined based on the relationship between the current charge level, the target battery charge level, and the second preset charge level. The vehicle is then controlled to operate according to the target sub-energy mode. This eliminates user ambiguity regarding energy modes, simplifies the operation process, and provides users with a more intention-oriented and uniquely selectable energy mode setting. Therefore, this solves the problems of unclear energy mode boundaries, user confusion, complex user experience, and limited energy efficiency optimization in related technologies.

[0020] Specifically, Figure 1 This is a flowchart illustrating an energy mode adjustment method provided in an embodiment of this application.

[0021] like Figure 1 As shown, the energy mode adjustment method includes the following steps: In step S101, the current battery charge level of the vehicle and the energy mode selected by the user are obtained.

[0022] There are two fixed energy modes available to users: the first energy mode and the second energy mode. In the first energy mode, the range extender is turned off first, and the vehicle is driven entirely by battery power. In the second energy mode, the vehicle integrates the functions of hybrid electric and fuel-priority modes, intelligently allocating energy between the power battery and the range extender. The first energy mode can be named "Forced Pure Electric" mode, and the second energy mode can be named "Intelligent Hybrid" mode. The specific names are set according to actual needs. The current battery charge value refers to the current state of charge of the vehicle battery, expressed as a percentage, reflecting the remaining usable battery power.

[0023] It is understood that the embodiments of this application first obtain the current charge value of the vehicle battery and the energy mode selected by the user. The energy mode has two fixed options: a first energy mode and a second energy mode. The current charge value of the vehicle battery and the energy mode selected by the user are used as the basis for the following energy mode adjustment.

[0024] In this embodiment of the application, before identifying the energy mode selected by the user, the method further includes: obtaining the current charge value of the vehicle battery; if the current charge value is less than or equal to a first preset charge value, then locking the energy mode to the second energy mode.

[0025] The first preset battery level is a set low battery threshold. When the current battery level of the vehicle is less than the first preset battery level, the first energy mode prioritizing pure electric power cannot be used. The first preset battery level is set according to actual needs and is not specifically limited here.

[0026] It is understood that, before identifying the energy mode selected by the user, this application embodiment needs to obtain the current charge value of the vehicle battery. If the current charge value is less than or equal to the first preset charge value, the energy mode is automatically locked to the second energy mode, and switching to the first energy mode is prohibited, so as to avoid the user's accidental operation when the battery is low, and at the same time ensure that the vehicle can still provide the necessary power through the range extender when the battery is low, so as to ensure driving safety and range capability.

[0027] It should be noted that the embodiments of this application also collect key parameters of the vehicle battery in real time, including SOC, SOH (State of Health), temperature gradient, etc., and complete data transmission through CAN (Controller Area Network) bus to monitor the battery status in real time through these parameters.

[0028] In step S102, when the user selects the first energy mode, a first preset energy value is obtained, and the target sub-energy mode of the vehicle is determined based on the relationship between the current energy value and the first preset energy value; when the user selects the second energy mode, a target battery energy value and a second preset energy value are obtained, and the target sub-energy mode of the vehicle is determined based on the relationship between the current energy value, the target battery energy value, and the second preset energy value.

[0029] The second preset battery level is a low battery threshold value, which can be set according to actual needs. It is not specifically limited here. The target battery level value will be described in detail below and will not be repeated here.

[0030] It is understood that the embodiments of this application adjust the energy mode through two different energy modes. When the user selects the first energy mode, a second preset energy value is obtained, and the target sub-energy mode to be executed by the vehicle is determined based on the relationship between the current battery energy value and the second preset energy value. When the user selects the second energy mode, the target battery energy value and the second preset energy value are obtained, and the relationship between the current energy value, the target battery energy value and the second preset energy value is comprehensively compared to dynamically decide the specific target sub-energy mode that the vehicle should enter, thereby realizing intelligent coordination and optimized allocation of oil and electric energy.

[0031] In this embodiment of the application, the target sub-energy mode includes a pure electric priority mode, a smart power supply mode, and a forced power supply mode, specifically: The pure electric priority mode includes turning off the range extender and relying entirely on the battery power to drive the vehicle; the intelligent power preservation mode includes calculating the output power of the vehicle battery and, when the target power is greater than the output power, activating the range extender to make up the difference; the forced power preservation mode includes activating the range extender, maintaining the vehicle's idling speed and charging the vehicle battery to maintain the current battery charge value to the target battery charge value.

[0032] It is understood that the target sub-energy modes in the embodiments of this application specifically include pure electric priority mode, intelligent power supply mode, and forced power supply mode. Pure electric priority mode means that the range extender is turned off and the vehicle is driven entirely by the power battery, maximizing the use of electric energy to improve economy. Intelligent power supply mode means that the current output power of the battery is calculated in real time. When the target power required by the vehicle exceeds the output power, the range extender is automatically started to make up the power difference, realizing the synergy of oil and electricity and on-demand energy supply. Forced power supply mode means that the range extender is actively started to continuously charge the power battery while maintaining the vehicle idling or low load driving until the battery charge recovers to the preset target battery charge value, ensuring the power reserve and system reliability in critical scenarios.

[0033] In this embodiment of the application, determining the target sub-energy mode of the vehicle based on the relationship between the current power value and the first preset power value includes: if the current power value is less than or equal to the first preset power value, controlling the vehicle to drive in a forced power-saving mode; if the current power value is greater than the first preset power value, controlling the vehicle to drive in a pure electric priority mode.

[0034] It is understood that, under the premise that the user selects the first energy mode, the specific target sub-energy mode to be executed is determined according to the relationship between the current power value and the first preset power value. Specifically, if the current power value is less than or equal to the first preset power value, it indicates that the battery power is at a low level. At this time, in order to avoid the power being depleted and affecting driving safety, the system automatically controls the vehicle to enter the forced power preservation mode, starts the range extender to charge and maintain basic driving. If the current power value is greater than the first preset power value, it is determined that the power is sufficient, and the vehicle is controlled to operate in pure electric priority mode, the range extender is turned off, and the vehicle is driven entirely by the battery to achieve optimal energy efficiency and driving economy.

[0035] In this embodiment of the application, the target battery charge value is a preset value set according to different driving scenarios and / or a preset value set by the user, and the target battery charge value does not exceed a preset range.

[0036] Among them, the target battery charge value refers to the specific charge level that the power battery is expected to maintain; the preset value set for different driving scenarios refers to the optimal target battery charge value automatically matched by the vehicle according to different driving scenarios, such as urban commuting, long-distance travel, and mountain driving. For example, the default target battery charge value for urban commuting is 30%, for long-distance travel it is 50%, and for mountain driving it is 60%; or, users can manually input or select the target charge value through the vehicle interface to meet their personalized needs; the preset range refers to the legal range of the target battery charge value (such as 15%~80%) set to ensure battery safety, lifespan, and vehicle performance. Settings exceeding this range will be automatically corrected.

[0037] It is understood that the embodiments of this application can be flexibly determined according to actual needs. Specifically, it can be automatically set by the system based on different driving scenarios (such as urban commuting scenarios, long-distance travel scenarios, and mountain driving scenarios), or it can be configured by the user through the human-machine interface. At the same time, in order to ensure battery safety and vehicle control stability, the target battery charge value is limited to a preset range defined by the system (e.g., 15%~80%). Any setting that exceeds this range will be automatically corrected or prompted as invalid, thereby improving the intelligent and personalized experience while ensuring the safety and reliability of vehicle energy management.

[0038] In this embodiment, determining the target sub-energy mode of the vehicle based on the relationship between the current battery level, the target battery level, and the second preset battery level includes: if the current battery level is less than or equal to the second preset battery level, and the second preset battery level is less than or equal to the target battery level, then controlling the vehicle to operate in a forced power-saving mode; if the current battery level is greater than the second preset battery level, and the current battery level is less than or equal to the target battery level, then controlling the vehicle to operate in an intelligent power-saving mode; if the current battery level is greater than the second preset battery level, and the current battery level is greater than the target battery level, then controlling the vehicle to operate in a pure electric priority mode.

[0039] It is understood that, in this embodiment of the application, when the user selects the second energy mode, the target sub-energy mode is intelligently determined based on the relationship between the current battery level, the target battery level, and the second preset battery level. Specifically, if the current battery level is less than or equal to the second preset battery level, and the second preset battery level is less than or equal to the target battery level, it indicates that the battery level is low and below the expected target battery level, requiring the activation of the forced power-saving mode to forcibly start the range extender to charge the battery and maintain basic driving. If the current battery level is greater than the second preset battery level and less than or equal to the target battery level, it indicates that the battery level is within a controllable range but has not yet reached the expected target battery level, then the intelligent power-saving mode is entered, and the range extender is called up as needed to make up for the power gap and dynamically maintain the battery level towards the target battery level. If the current battery level is greater than both the second preset battery level and the target battery level, it indicates that the battery level is sufficient and exceeds the maintenance requirements, and the pure electric priority mode can be switched to, the range extender is turned off, and battery driving is used first to achieve the best energy efficiency and driving economy.

[0040] In step S103, the vehicle is controlled to drive according to the target sub-energy mode.

[0041] It is understood that after determining the target sub-energy mode according to the aforementioned logic, the embodiments of this application will automatically execute the corresponding energy management strategy. That is, if the target sub-energy mode is the pure electric priority mode, the range extender will be turned off and the vehicle will be driven entirely by the power battery; if the target sub-energy mode is the intelligent power-saving mode, the power demand will be monitored in real time, and the range extender will be activated to dynamically make up the difference when the battery output is insufficient, so as to maintain a stable power level; if the target sub-energy mode is the forced power-saving mode, the range extender will be forcibly activated to charge the battery while ensuring basic driving, until the power level recovers to a safe level. Through the above control, the user only needs to select one of the first and second energy modes, and the vehicle can automatically confirm the target sub-energy mode and operate efficiently and safely according to the determined target sub-energy mode, thereby eliminating the user's cognitive ambiguity about the energy mode and simplifying the operation process.

[0042] The energy mode adjustment method proposed in this application integrates two easily understandable energy modes for user selection. During energy mode adjustment, the current battery charge level of the vehicle and the user-selected energy mode are obtained. When the user selects the first energy mode, a second preset charge level is obtained, and the target sub-energy mode of the vehicle is determined based on the relationship between the current charge level and the first preset charge level. When the user selects the second energy mode, the target battery charge level and the second preset charge level are obtained, and the target sub-energy mode of the vehicle is determined based on the relationship between the current charge level, the target battery charge level, and the second preset charge level. The vehicle is then controlled to operate according to the target sub-energy mode, eliminating user ambiguity regarding energy modes, simplifying the operation process, and providing users with a more intention-oriented and uniquely selectable energy mode setting.

[0043] The energy mode adjustment method is further described below through a specific embodiment.

[0044] In this embodiment, the first energy mode is named the forced pure electric mode, and the second energy mode can be named the intelligent electric hybrid mode.

[0045] The layout of the energy mode HMI (Human-Machine Interface) interface in this embodiment is as follows: Figure 2 As shown, it can provide users with more intention-oriented and more unique energy mode settings.

[0046] Specifically, the forced pure electric mode turns off the range extender and relies entirely on battery power to drive the vehicle, meeting the user's need for pure electric driving in scenarios where charging is convenient. It also clearly informs the user that the forced pure electric mode is unavailable when the battery level is below 5%, preventing users from accidentally operating it when the battery is low. The intelligent electric hybrid mode integrates the features of hybrid electric and some fuel priority modes. When the battery level is between 20% and 70%, the vehicle intelligently allocates energy usage between the power battery and the range extender.

[0047] This embodiment implements pattern determination through a three-level data fusion architecture, specifically including a basic data layer, a logic determination layer, and an execution instruction layer. The basic data layer includes a battery management system and a target battery charge setting module. The battery management system collects key battery parameters in real time, including SOC, SOH, and temperature gradient, and transmits the data via a CAN bus. Each battery module is equipped with two temperature sensors to ensure accurate temperature monitoring. The target battery charge value can be preset by the user, ranging from 15% to 80%, with a step value of 5%. The system can also set default values ​​according to different scenarios, such as 30% for urban commuting, 50% for long-distance travel, and 60% for mountain driving, providing users with convenient initial settings.

[0048] The logic decision layer determines the applicable mode based on the mode decision matrix, as shown in Table 1. Table 1 is a correspondence table between the current battery level, the target battery level, and the applicable mode.

[0049] Table 1

[0050] The execution instruction layer is used to output control signals to critical components, including: Send control commands to the range extender ECU (Electronic Control Unit): Based on the current energy strategy, output the start / stop command and target power setting value of the range extender to adjust the engine power generation to meet the driving or charging needs; Control the high-voltage distribution box: dynamically switch the high-voltage power supply path between the power battery and the range extender. For example, disconnect the high-voltage output of the range extender in pure electric mode, and connect and coordinate the dual-source power supply in hybrid mode. Adjusting the DC / DC converter: Switching the power source of the 12V low-voltage system according to the system status (such as being powered by the power battery via DC / DC converter, or being powered by it as an auxiliary power source when the range extender is running), to ensure the stable operation of the low-voltage electrical system (lights, ECU, HMI, etc.).

[0051] Figure 3 This is a flowchart of the energy mode adjustment method in this embodiment. In this embodiment, the first preset power value is set to 5%, and the second preset power value is set to 20%. Figure 3 As shown, the specific process of the energy mode adjustment method in this embodiment is as follows: 1. Users select an energy mode.

[0052] 2. If the user selects the "forced pure electric" energy mode, then determine the relationship between the current power value and the first preset power value.

[0053] If the current battery level is less than or equal to 5%, it indicates that the battery level is low. To prevent the battery from running out and affecting driving safety, the system automatically controls the vehicle to enter a forced power-saving mode and performs the following actions: Force the range extender to start and lock the mode to ensure normal vehicle operation.

[0054] If the current battery level is greater than 5%, the battery is considered sufficient, and the following actions are performed: Disconnect the range extender's fuel solenoid valve to cut off the fuel supply; Close the battery-driven main relay to connect the power battery circuit; A DC / AC (DC / AC Inverter) converter supplies power to drive a motor.

[0055] 3. If the user selects "Intelligent Hybrid" mode, the system will determine the relationship between the current battery level, the target battery level, and the second preset battery level. If the current battery level is less than or equal to 20%, and the second preset battery level is less than or equal to the target battery level, it indicates that the battery level is low and below the expected target battery level. In this case, the forced power-saving mode needs to be activated to forcibly start the range extender to charge the battery and maintain basic driving, performing the following actions: Set the range extender control parameters, including: setting the minimum speed to ensure stable power generation; setting the power generation to meet the driving and charging needs; and enabling the range extender to achieve dynamic power optimization.

[0056] If the current battery level is greater than 20% and less than or equal to the target battery level, it indicates that the battery level is within a controllable range but has not yet reached the desired target battery level. In this case, the intelligent power-saving mode is activated, and the range extender is used as needed to supplement the power gap, dynamically maintaining the battery level towards the target battery level, and performing the following actions: Real-time acquisition of the drive motor's required power; Calculate the battery's output power. When the required power exceeds the current power, activate the range extender to make up the difference and ensure stable power supply.

[0057] If the current battery level is greater than 20% and the target battery level, it indicates that the battery has sufficient charge and exceeds the maintenance requirements. You can switch to pure electric priority mode, turn off the range extender, and prioritize battery power to achieve optimal energy efficiency and driving economy. Perform the following actions: The range extender is completely shut down, and the fuel line solenoid valve is de-energized.

[0058] Next, the energy mode adjustment device proposed according to the embodiments of this application is described with reference to the accompanying drawings.

[0059] Figure 4 This is a block diagram of an energy mode adjustment device according to an embodiment of this application.

[0060] like Figure 4 As shown, the energy mode adjustment device 10 includes: an acquisition module 201, a determination module 202, and a control module 203.

[0061] The acquisition module 201 is used to acquire the current battery level of the vehicle and the energy mode selected by the user; the determination module 202 is used to acquire a second preset battery level when the user selects the first energy mode, and determine the target sub-energy mode of the vehicle based on the relationship between the current battery level and the first preset battery level; when the user selects the second energy mode, it acquires the target battery level and the second preset battery level, and determines the target sub-energy mode of the vehicle based on the relationship between the current battery level, the target battery level, and the second preset battery level; the control module 203 is used to control the vehicle to drive according to the target sub-energy mode.

[0062] In this embodiment of the application, a judgment module is also included, wherein the judgment module is further configured to: obtain the current charge value of the vehicle battery before identifying the energy mode selected by the user; if the current charge value is less than or equal to a first preset charge value, then lock the energy mode as the second energy mode.

[0063] In the embodiments of this application, the target sub-energy mode includes pure electric priority mode, intelligent power supply mode and forced power supply mode.

[0064] In this embodiment, the pure electric priority mode includes turning off the range extender and relying entirely on the battery power to drive the vehicle; the intelligent power preservation mode includes calculating the output power of the vehicle battery and, when the target power is greater than the output power, starting the range extender to make up the difference in power; the forced power preservation mode includes starting the range extender, maintaining the vehicle idling speed and charging the vehicle battery to maintain the current battery charge value to the target battery charge value.

[0065] In this embodiment of the application, the determining module 202 is further configured to: if the current battery level is less than or equal to the first preset battery level, control the vehicle to drive in a forced power-saving mode; if the current battery level is greater than the first preset battery level, control the vehicle to drive in a pure electric priority mode.

[0066] In this embodiment of the application, the determining module 202 is further configured to: if the current battery level is less than or equal to a second preset battery level, and the second preset battery level is less than or equal to a target battery level, then control the vehicle to drive in a forced power-saving mode; if the current battery level is greater than the second preset battery level, and the current battery level is less than or equal to a target battery level, then control the vehicle to drive in an intelligent power-saving mode; if the current battery level is greater than the second preset battery level, and the current battery level is greater than a target battery level, then control the vehicle to drive in a pure electric priority mode.

[0067] In this embodiment of the application, the target battery charge value is a preset value set according to different driving scenarios and / or a preset value set by the user, and the target battery charge value does not exceed a preset range.

[0068] The energy mode adjustment device proposed in this application integrates two easily understandable energy modes for user selection. During energy mode adjustment, it acquires the current battery charge level of the vehicle and the user-selected energy mode. When the user selects the first energy mode, it acquires a second preset charge level and determines the vehicle's target sub-energy mode based on the relationship between the current charge level and the first preset charge level. When the user selects the second energy mode, it acquires the target battery charge level and the second preset charge level and determines the vehicle's target sub-energy mode based on the relationship between the current charge level, the target battery charge level, and the second preset charge level. By controlling the vehicle to operate according to the target sub-energy mode, it eliminates user ambiguity regarding energy modes, simplifies the operation process, and provides users with a more intention-oriented and uniquely selectable energy mode setting.

[0069] It should be noted that the foregoing explanation of the energy mode adjustment method embodiment also applies to the energy mode adjustment device of this embodiment, and will not be repeated here.

[0071] When the processor 302 executes the program, it implements the energy mode adjustment method provided in the above embodiments.

[0072] Furthermore, the vehicle also includes: Communication interface 303 is used for communication between memory 301 and processor 302.

[0073] The memory 301 is used to store computer programs that can run on the processor 302.
