Technical Field
[0002] Embodiments of the present application relate to the field of vehicle technology, and more specifically, to a vehicle control method, a vehicle control device, and a vehicle. Background Art
[0003] Compared to other electric vehicles, extended-range electric vehicles (EREVs) offer advantages such as a simpler system configuration, longer driving range, and lower costs, and are currently gaining widespread adoption in the electric vehicle sector. EREVs are equipped with a range extender, which provides additional power to increase the vehicle's range. The engine (e.g., a fuel-powered engine) drives a generator to generate electricity, thereby increasing the vehicle's range.
[0004] Traditional extended-range electric vehicles (EREVs) offer configurable modes, including hybrid electric vehicle (HEV) and pure electric vehicle (EV). However, improper mode switching often leads to a negative user experience. Therefore, improving the user experience with EREVs is a pressing technical challenge.
[0005] Summary of the Invention
[0006] The embodiments of the present application provide a vehicle control method, a control device, and a vehicle, which can improve the user experience of using an extended-range electric vehicle.
[0007] In a first aspect, a method for controlling a vehicle is provided. The vehicle includes a battery and a range extender. Configurable modes of the vehicle include a first configuration mode, a second configuration mode, and a third configuration mode. When the first configuration mode is activated, the range extender enters a first operating mode when an actual SOC value of the battery is less than or equal to a first threshold value. In the first operating mode, the range extender is configured to power the vehicle. When the second configuration mode is activated, the range extender enters the first operating mode when an actual SOC value of the battery is less than or equal to a second threshold value, the second threshold value being less than the first threshold value. When the third configuration mode is activated, the range extender enters the first operating mode or the second operating mode when the actual SOC value of the battery is less than or equal to a third threshold value, wherein the third threshold value is less than or equal to the first threshold value and greater than the second threshold value. In the second operating mode, the range extender is configured to idle.
[0008] The method includes: when the second configuration mode and the third configuration mode are in an activated state and the SOC value of the battery is less than or equal to the third threshold value, obtaining first state information of the vehicle, the first state information including the power demand of the vehicle; and determining whether the range extender enters the first operating mode or the second operating mode according to the first state information.
[0009] Among them, the range extender entering the first working mode can be described as starting the range extender, and the range extender starting makes the range extender configured to supply power to the vehicle; the range extender entering the second working mode can be described as pre-starting of the range extender, in which the range extender is configured to idle, so that the range extender is in a state ready to output (i.e., an immediate power generation state).
[0010] In an embodiment of the present application, when the second configuration mode and the third configuration mode are activated, the first status information of the vehicle can be obtained when the SOC value of the battery is less than or equal to the third threshold value, and the range extender can be determined to enter the first operating mode or the second operating mode based on the first status information. On the one hand, the SOC threshold for the range extender to enter the first operating mode can be lowered to the second threshold value (i.e., the start threshold of the range extender is lowered to the second threshold value), thereby achieving battery priority power supply. On the other hand, when the actual SOC value of the battery is less than or equal to the third threshold value, the range extender can be determined to enter the first operating mode or the second operating mode based on the first status information of the vehicle, thereby avoiding the situation where the vehicle's power is insufficient due to the status information during the battery priority power supply process, thereby improving the user experience of using the extended-range electric vehicle.
[0011] In combination with the first aspect, in certain implementations of the first aspect, determining, based on the first status information, that the range extender enters the first operating mode or the second operating mode includes: if the output power of the battery is greater than or equal to the power requirement of the vehicle, controlling the range extender to operate in the second operating mode; if the output power of the battery is less than the power requirement of the vehicle, controlling the range extender to operate in the first operating mode.
[0012] In an embodiment of the present application, when the output power of the battery is greater than or equal to the power requirement of the vehicle, the range extender can be controlled to operate in the second operating mode, and when the output power of the battery is less than the power requirement of the vehicle, the range extender can be controlled to operate in the first operating mode, thereby ensuring the power level of the entire vehicle and improving the user experience.
[0013] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: obtaining a user instruction, the user instruction being used to instruct activation of the second configuration mode and the third configuration mode; and controlling activation of the second configuration mode and the third configuration mode according to the user instruction.
[0014] In an embodiment of the present application, the activation of the second configuration mode and the third configuration mode can be controlled based on user instructions, that is, the user can decide whether to activate the second configuration mode and the third configuration mode according to his or her own wishes, thereby improving the user experience.
[0015] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: obtaining second state information of the vehicle, the second state information of the vehicle including the power-on state of the vehicle, the charge state of the battery, and the first ambient temperature state of the vehicle; determining whether the second state information of the vehicle meets the entry conditions of the second configuration mode and the third configuration mode; if the second state information of the vehicle meets the entry conditions, controlling the activation of the second configuration mode and the third configuration mode; if the second state information of the vehicle does not meet the entry conditions, controlling the activation or maintaining the first configuration mode.
[0016] In this embodiment of the present application, the second state information of the vehicle can be used to determine whether it meets the entry conditions of the second configuration mode and the third configuration mode. If it meets the conditions, activation is controlled, and if it does not meet the conditions, activation is not controlled. This can avoid the situation where the vehicle's power is insufficient when the second state information does not meet the entry conditions but forced entry is performed, thereby improving the user experience.
[0017] In combination with the first aspect, in certain implementations of the first aspect, when the second configuration mode and the third configuration mode are in an activated state, the method further includes: obtaining third state information of the vehicle, the third state information of the vehicle including the speed state of the vehicle, the second ambient temperature state of the vehicle, the climbing state of the vehicle, and the switch state of the second configuration mode of the vehicle; determining whether the third state information of the vehicle meets the exit conditions of the second configuration mode and the third configuration mode; if any item of the third state information of the vehicle meets the exit condition, controlling the exit from the second configuration mode and the third configuration mode; if none of the third state information of the vehicle meets the exit condition, controlling the keeping of the second configuration mode and the third configuration mode in an activated state.
[0018] In an embodiment of the present application, it is possible to determine whether the third state information of the vehicle complies with the second configuration mode and the exit conditions of the third configuration mode based on the third state information of the vehicle, and exit when it complies, and not exit when it does not comply, so as to avoid scenarios with large power requirements or large dynamic requirements, ensure the dynamic performance of the entire vehicle, and thus improve the user experience.
[0019] In combination with the first aspect, in certain implementations of the first aspect, when the range extender operates in the first operating mode, the method further includes: controlling activation of the second configuration mode; or controlling activation of the second configuration mode and the third configuration mode.
[0020] In an embodiment of the present application, when the range extender operates in the first operating mode, the second configuration mode may be controlled to be activated; or, the second configuration mode and the third configuration mode may be controlled to be activated. That is, when the range extender operates in the first operating mode, the battery may be forced to be used for power supply, thereby improving the user experience.

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
[0045] The present application scheme can be applied to vehicles, which are vehicles in a broad sense, and can be transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as mowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of the present application do not specifically limit the type of vehicle. For example, the vehicle can be a transportation vehicle such as an airplane or a ship.
[0046] The embodiments of the present application can also be applied to other mobile devices involved in the fields of transportation, home, industry, construction, agriculture, entertainment, etc., and the present application does not limit this. For ease of description, the following description is based on a vehicle as an example.
[0047] FIG1 is an example of a functional block diagram of a vehicle 100 provided in an embodiment of the present application. As shown in FIG1 , the vehicle 100 may include a perception system 120, a display device 130, and a computing platform 150, wherein the perception system 120 may include several sensors for sensing environmental information about the surroundings of the mobile device 100, such as road information, ambient temperature information, ambient brightness information, etc. For example, the perception system 120 may include a positioning system, which may be a global positioning system (GPS), a BeiDou system or other positioning systems, an inertial measurement unit (IMU), a laser radar, a millimeter wave radar, an ultrasonic radar, and a camera device. The perception system 120 may also include sensors of the internal systems of the monitored vehicle 100 (for example, in-vehicle throttle depth, in-vehicle air quality monitor, fuel gauge, oil temperature gauge, etc.).
[0048] Display devices 130 are primarily categorized into two types: in-vehicle displays; and projection displays, such as heads-up displays (HUDs). An in-vehicle display is a physical display and a crucial component of an in-vehicle infotainment system. Multiple displays can be installed within the cabin, including a digital instrument panel, a central control panel, a display in front of the front passenger (also known as the front passenger), a display in front of the left rear passenger, and a display in front of the right rear passenger. Even the vehicle windows can function as display screens. A head-up display (HUD), also known as a head-up display, projects information such as vehicle speed, fuel level, and navigation information onto the windshield of the vehicle 100. Reflected by the windshield, a virtual image forms a certain distance directly in front of the driver's line of sight, allowing the driver to view this information without having to lower their head. This reduces the driver's time spent shifting their gaze, avoids pupil changes caused by this shift, and improves driving safety and comfort. HUDs include combined head-up displays (C-HUD), windshield heads-up displays (W-HUD), and augmented reality heads-up displays (AR-HUD). At present, traditional HUD mainly displays vehicle instrument information such as vehicle speed and fuel level. Compared with traditional HUD, AR-HUD has a wider field of view and a farther screen. It can integrate AR images with real-world environment information, enhancing the driver's acquisition of road information and realizing functions such as AR navigation, adaptive cruise control, and lane departure warning.
[0049] Some or all functions of vehicle 100 may be controlled by computing platform 150. Computing platform 150 may include one or more processors, such as processors 151 to 15n (n is a positive integer). A processor is a circuit capable of processing signals. In one implementation, the processor may be a circuit capable of reading and executing instructions, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor may implement certain functions through the logical relationships of hardware circuits. The logical relationships of the hardware circuits may be fixed or reconfigurable. For example, the processor may be a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration file to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 150 can also include a memory for storing instructions. Some or all of the processors 151 to 15n can call the instructions in the memory and execute the instructions to achieve corresponding functions.
[0050] Figure 2 is an example diagram of a vehicle cabin scene provided by an embodiment of the present application. One or more cameras may be installed inside or outside the cabin to capture images inside or outside the cabin, such as cameras for a driver monitoring system (DMS), a cabin monitoring system (CMS), and a dashcam. Figure 2 uses a camera installed on the A-pillar as an example. The cameras used to capture images inside and outside the cabin can be the same camera or different cameras. In addition, the cabin is also equipped with an onboard display screen. Figure 2 uses a display screen installed in the center console area as an example. Optionally, the onboard display screen can display one or more of the following: required driving information, audio and video entertainment information, vehicle configuration information, etc.; the onboard display screen can also enable human-vehicle interaction. For example, the user can click on relevant icons or enter commands on the display screen to control the vehicle; for example, the vehicle can pop up a message on the onboard display screen to remind the user, or the vehicle can display operation options on the onboard display screen, allowing the user to select according to actual needs. It should be understood that the location of the camera that captures image information in the cabin in the embodiments of the present application is not specifically limited. The camera can be located on the A-pillar as shown in FIG2 , or below the steering wheel, or on the B-pillar, or near the rearview mirror, etc.
[0051] The following briefly introduces the background technology involved in this application scheme by taking an extended-range electric vehicle as an example.
[0052] An extended-range electric vehicle (EREV) consists of a battery and a range extender. The range extender provides additional electrical energy to increase the vehicle's range. Essentially, the range extender is a combination of an engine and a generator. The engine (e.g., a fuel engine) drives the generator to generate electricity, thereby increasing the vehicle's range. To reduce vehicle costs, the battery capacity in EREVs is generally small. Therefore, at low SOCs (e.g., below 20%), the battery charge is low, resulting in poor power performance when powered by the battery.
[0053] Traditional extended-range electric vehicles (EREVs) have two configurable modes: HEV and EV. When HEV mode is activated, the vehicle system typically sets a threshold. When the battery's actual SOC is greater than or equal to this threshold, the battery is used for power. When the battery's actual SOC is less than this threshold, the range extender is activated, using the engine to generate electricity. To ensure vehicle power, traditional solutions often set a high threshold (e.g., 20%). This means that when the battery's actual SOC is high, the range extender is forced to activate, preventing the user from using the remaining battery charge. This creates a poor user experience for cost-sensitive users. For example, if the user's current driving scenario does not require high power, they could reach their destination using the remaining 20% charge and then recharge at a charging station. However, due to the system's threshold setting, the system automatically switches to the range extender for power. However, the use of the range extender requires fuel, which increases vehicle costs and increases vehicle noise, vibration, and harshness (NVH), resulting in a poor user experience.
[0054] EV mode, also known as pure electric mode, when EV mode is activated, the start threshold of the range extender is low (for example, as low as 10%). Therefore, users who are sensitive to cost and noise can choose EV mode, so that even when the actual SOC value of the battery is lower than the above-mentioned 20% threshold, the battery can continue to be used for power supply. However, based on this mode, when the actual SOC value is between 10% and 20%, the vehicle's power will be insufficient. This has no effect on general urban roads, but in scenarios such as high speed, climbing, rapid acceleration, and low ambient temperature, the battery power supply cannot provide sufficient power to drive the vehicle, resulting in a poor user experience.
[0055] Based on this, an embodiment of the present application provides a vehicle control method that can prioritize battery power supply without affecting the power performance of the entire vehicle, thereby improving the user experience.
[0056] Before introducing the control method provided in the embodiments of the present application, it should be noted that the vehicle involved in the present application includes a battery and a range extender, and the configurable modes of the vehicle include a first configuration mode, a second configuration mode, and a third configuration mode. These three configuration modes are described below.
[0057] When the first configuration mode is activated, the range extender enters the first operating mode when the actual SOC value of the battery is less than or equal to a first threshold. In this first operating mode, the range extender is configured to power the vehicle. Specifically, when the first configuration mode is activated, when the actual SOC value of the battery is greater than the first threshold, the battery is used for power supply; when the actual SOC value of the battery is less than or equal to the first threshold, the range extender enters the first operating mode to power the vehicle (specifically, using the engine to generate electricity to power the vehicle). This first configuration mode can also be understood as the HEV mode described above, and the first threshold can be, for example, 20%. It should be noted that the phrase "when the first configuration mode is activated" can also be described as "in the first configuration mode" or "entering the first configuration mode." "The range extender enters the first operating mode" can also be described as "the range extender is activated." Range extender activation refers to the range extender being in a state of powering the vehicle, but this embodiment of the application does not distinguish between the two. It should be understood that the range extender powering the vehicle can be understood as the range extender powering the vehicle while the vehicle is in motion, providing power to the vehicle, or it can be understood as the range extender charging the vehicle's battery.
[0058] When the second configuration mode is activated, the range extender enters the first operating mode when the actual SOC value of the battery is less than or equal to the second threshold, and the second threshold is less than the first threshold. Specifically, when the second configuration mode is activated, when the actual SOC value of the battery is greater than the second threshold, the battery is used for power supply; when the actual SOC value of the battery is less than or equal to the second threshold, the range extender enters the first operating mode to power the vehicle. Because the second threshold is less than the first threshold, the battery can still be used for power supply when the actual SOC value of the battery is between the first threshold and the second threshold. The second configuration mode can also be understood as the above-mentioned EV mode. Based on the second configuration mode, the SOC threshold for the range extender to enter the first operating mode (i.e., the start-up threshold of the range extender) is lower, and the battery can be used for power supply first. The second threshold can be, for example, 10%. It should also be noted that the above-mentioned "when the second configuration mode is activated" can also be described as "in the second configuration mode" or "when entering the second configuration mode", and the embodiments of the present application do not distinguish between them.
[0059] When the third configuration mode is activated, the range extender enters the first or second operating mode when the actual battery SOC value is less than or equal to a third threshold. In the second operating mode, the range extender is configured to idle, wherein the third threshold is less than or equal to the first threshold and greater than a second threshold, which may be, for example, 15%. In other words, the range extender can enter both the first and second operating modes when the actual battery SOC value is less than or equal to the third threshold. "The range extender enters the second operating mode" can also be described as "pre-starting the range extender" or "pre-starting the engine." Starting the range extender essentially involves idling the range extender (or engine). This idling puts the range extender in a ready-to-run state, essentially preparing it for full operation. This third configuration mode can also be understood as a pre-start range extender mode. It should be noted that the phrase "when the third configuration mode is activated" can also be described as "in the third configuration mode" or "upon entering the third configuration mode." This embodiment of the present application does not distinguish between these two terms.
[0060] The above-mentioned first, second, and third thresholds are merely examples. In actual operation, they need to be determined in conjunction with specific circumstances, and this application does not impose any limitations thereon. For example, if the first threshold is 20% and the second threshold is 10%, and if the actual battery SOC value is between 15% and 20%, the vehicle's power performance in driving at high speeds, climbing a slope, rapid acceleration, or in low ambient temperatures will not be affected or will be slightly affected even if the battery is used for power. However, if the battery SOC value is below 15%, the vehicle's power performance in driving at high speeds, climbing a slope, rapid acceleration, or in low ambient temperatures will be seriously affected. In this case, the range extender can be pre-activated when the battery SOC value is below 15%, allowing the range extender to enter a state ready for output, so that the range extender can immediately enter a power generation state when encountering driving at high speeds, climbing a slope, rapid acceleration, or in low ambient temperatures.
[0061] Based on the above three configurations, the vehicle control method provided by the embodiment of the present application is described in detail below in conjunction with Figure 3. Figure 3 is an example diagram of a vehicle control method provided by an embodiment of the present application. It should be understood that method 300 can be executed by one or more processors in the computing platform 150 described above. As shown in Figure 3, method 300 includes steps S310 and S320, which are described in detail below.
[0062] Optionally, before executing method 300 , the second configuration mode and the third configuration mode may be activated first, that is, the control enters the second configuration mode and the third configuration mode.
[0063] In one implementation, the vehicle can be controlled to enter the second and third configuration modes based on user operations. Specifically, the user can send a command to the vehicle, which is used to activate (i.e., control the vehicle to enter) the second and third configuration modes; the vehicle then receives the user command and controls the activation (i.e., controls the vehicle to enter) the second and third configuration modes according to the user command.
[0064] In practice, icons for entering the second and third configuration modes can be set on the vehicle's in-cabin display screen (see icons 1 and 2 in FIG. 4 ). Users can send a command to the vehicle by clicking the icons for entering the second and third configuration modes on the in-cabin display screen. Alternatively, users can click the "Settings" icon on the in-cabin display screen and select a vehicle mode in the in-cabin settings system to instruct the vehicle to enter the second and third configuration modes. Alternatively, buttons for entering the second and third configuration modes can be set in the vehicle's in-cabin (see buttons 1 and 2 in FIG. 5 ). Users can send a command to the vehicle by clicking or toggling the buttons for entering the second and third configuration modes. Alternatively, users can send a command to the vehicle via voice, for example, by sending the voice message "Interactive assistant, please enter the second and third configuration modes!" (see FIG. 6 ) to instruct the vehicle to enter the second and third configuration modes. It should be understood that the above methods are merely examples and do not constitute a limitation on the present application.
[0065] The second and third configuration modes can be implemented via a single icon or button. Clicking the icon or button controls entry into the second and third configuration modes. Alternatively, two icons or buttons can be used to control entry into the second and third configuration modes, respectively. For example, a user can enter the second configuration mode by clicking the icon or button for the second configuration mode, and enter the third configuration mode by clicking the icon or button for the third configuration mode.
[0066] Optionally, after the vehicle receives the user's instruction, it can remind the user to confirm again whether to enter the second configuration mode and the third configuration mode through the vehicle display screen or voice prompt (see Figure 7). It should be understood that the second confirmation can prevent the user from entering the second configuration mode and the third configuration mode due to accidental touch.
[0067] Optionally, the above-mentioned user sending instructions to the vehicle can be the user actively sending instructions to the vehicle, or the user sending instructions to the vehicle after a reminder or selection initiated by the vehicle (for example, the vehicle can, after power-on, consult the user through human-vehicle interaction whether to enter the second configuration mode and the third configuration mode; for example, when driving in the first configuration mode, the vehicle can remind the user when it detects that the range extender is about to be started or has been started, allowing the user to operate according to his or her own wishes).
[0068] In another implementation, the vehicle may intelligently control the entry into the second and third configuration modes. For example, the vehicle may autonomously enter the second and third configuration modes based on the current scene and vehicle status; or, for another example, the vehicle may prioritize the activation of the second and third configuration modes. This application does not limit this.
[0069] Optionally, when the range extender is operating in the first operating mode (i.e., when it is activated), the second configuration mode can be activated; or the second configuration mode and the third configuration mode can be activated (i.e., the vehicle can be controlled to enter the second configuration mode; or the vehicle can be controlled to enter the second configuration mode and the third configuration mode) to enter the battery-powered state. In other words, when the range extender is activated, the battery power supply can be forced to be used, thereby improving the user experience.
[0070] S310: Acquire first state information of the vehicle. Specifically, when the second configuration mode and the third configuration mode are activated and the SOC value of the battery is less than or equal to a third threshold, the first state information of the vehicle can be acquired.
[0071] Optionally, the first state information may include the vehicle's power demand. It should be understood that different power requirements may apply to different vehicle scenarios. For example, in scenarios such as high speed, hill climbing, and rapid acceleration, the power demand is higher, and accordingly, the vehicle's dynamic performance requirements are higher. In smooth urban traffic, the power demand is lower, and accordingly, the vehicle's dynamic performance requirements are lower.
[0072] In actual operation, the power demand can be distinguished based on the throttle depth and the duration at that depth. Specifically, when the throttle depth is large and the duration is long, the current power demand is considered large; otherwise, the current power demand is considered small.
[0073] Optionally, the first status information may also include information such as the ambient temperature status of the vehicle, without limitation.
[0074] S320, determines whether the range extender enters the first working mode or the second working mode according to the first state information of the vehicle. It can also be understood as determining whether the range extender needs to be in the pre-start state or the output state according to the first state information of the vehicle. Alternatively, it can be understood as determining whether the range extender enters the output state from the pre-start state according to the first state information of the vehicle. It should be understood that when the actual SOC value of the battery is just less than the third threshold value, if it is determined according to the first state information at that time that the range extender needs to enter the second working mode, then the range extender is controlled to enter the second working mode first. If, during the subsequent vehicle driving process, it is determined that the range extender needs to enter the first working mode according to the updated first state information, the range extender can be controlled to switch from the second working mode to the first working mode (that is, switch from the pre-start state to the output state).
[0075] In an embodiment of the present application, when the second configuration mode and the third configuration mode are activated, the first status information of the vehicle can be obtained when the SOC value of the battery is less than or equal to the third threshold value, and the range extender can be determined to enter the first operating mode or the second operating mode based on the first status information. On the one hand, the SOC threshold for the range extender to enter the first operating mode can be lowered to the second threshold value (i.e., the start threshold of the range extender is lowered to the second threshold value), thereby achieving battery priority power supply. On the other hand, when the actual SOC value of the battery is less than or equal to the third threshold value, the range extender can be determined to enter the first operating mode or the second operating mode based on the first status information of the vehicle, thereby avoiding the situation where the vehicle's power is insufficient due to the status information during the battery priority power supply process, thereby improving the user experience of using the extended-range electric vehicle.
[0076] Optionally, when the vehicle's power demand is greater than or equal to a preset value, the range extender can be controlled to operate in the first operating mode, or switched from the second operating mode to the first operating mode (i.e., switching from the pre-start state to the output state). When the vehicle's power demand is less than the preset value, the range extender can be controlled to operate in the second operating mode (i.e., in the pre-start state).
[0077] Optionally, when the battery's output power is greater than or equal to the vehicle's power requirement, the range extender can be controlled to operate in the second operating mode (i.e., in the pre-start state); when the battery's output power is less than the vehicle's power requirement, the range extender can be controlled to operate in the first operating mode, or switch from the second operating mode to the first operating mode (i.e., switching from the pre-start state to the output state), thereby ensuring the vehicle's power level and improving the user experience. It should be understood that the battery's output power is affected by the battery charge and the ambient temperature. Generally, the lower the battery charge and the lower the ambient temperature, the lower the battery's output power.
[0078] Optionally, in actual operation, when it is detected that the throttle depth is greater than a preset value (for example, 70%) and the duration is greater than a preset value (for example, 3s), the range extender is controlled to enter the output state from the pre-start state, otherwise it remains in the pre-start state.
[0079] It should be understood that there will be a time delay when the engine is started, which can be as long as tens of seconds. If the range extender is started only when the actual SOC value of the battery is less than or equal to the third threshold and a high power demand scenario is encountered, the vehicle will have insufficient power during the startup process, resulting in a poor user experience. In the present application, when the actual SOC value of the battery is less than or equal to the third threshold, if there is no high power scenario, the range extender can be pre-started, and based on the first state information of the vehicle, it is determined whether the range extender should enter the output state (i.e., whether to enter the output state from the pre-start state), so that when a high power demand scenario is encountered, the range extender can directly enter the output state (i.e., the power generation state), avoiding the situation where the vehicle has insufficient power due to the untimely output of the range extender.
[0080] It should be understood that the purpose of pre-starting the range extender is to bring the temperature of the engine's cooling medium to a preset value (e.g., 70°C). Based on this preset temperature, the range extender can be in a state ready for output. Therefore, for pre-starting the range extender, if the actual temperature of the engine's cooling medium in the range extender is less than the preset value (e.g., 70°C), the engine needs to be put into an idle state until the temperature of the cooling medium reaches the preset value. If the actual temperature of the engine's cooling medium has already reached the preset value, the engine does not need to be idle, and the range extender can also be in a state ready for output. Therefore, the temperature of the cooling medium can be used to determine whether the engine needs to be idle during pre-start.
[0081] Optionally, the second configuration mode and the third configuration mode may further include entry conditions. Only when the entry conditions are met can the second configuration mode and the third configuration mode be activated.
[0082] Specifically, the second state information of the vehicle can be obtained first; then it is determined whether the second state information of the vehicle meets the entry conditions of the second configuration mode and the third configuration mode; if the second state information of the vehicle meets the entry conditions, the second configuration mode and the third configuration mode are controlled to be activated (i.e., the vehicle is controlled to enter); if the second state information of the vehicle does not meet the entry conditions, the first configuration mode is controlled to be activated or maintained (i.e., the vehicle is controlled to enter).
[0083] Optionally, the second status information of the vehicle may include the power-on status of the vehicle, the power status of the battery, and the first ambient temperature status of the vehicle.
[0084] For example, it can be set that the entry conditions are met when the vehicle is in a high-voltage power-on state, the actual SOC value of the battery is greater than a preset value (for example, 10%), and the ambient temperature of the vehicle is greater than a preset value (for example, 10°C). If any one of the conditions is not met, the entry conditions are not met.
[0085] Optionally, the second state information of the vehicle listed above is only an example. In practice, it may include more or less state information, which needs to be determined in combination with the actual driving scenario of the vehicle. This application does not limit this. Based on this, the entry conditions can also be adjusted according to the second state information. For example, the second state information of the vehicle can also include whether it is in a high-speed driving state. Correspondingly, the entry conditions can also include that the vehicle's driving speed is lower than a preset value, and the predicted duration of high-speed driving is shorter than a preset value. Only when the entry conditions are met.
[0086] In the embodiment of the present application, it is possible to determine whether the second state information of the vehicle meets the entry conditions of the second configuration mode and the third configuration mode based on the second state information of the vehicle. If it meets the conditions, activation is controlled (i.e., entry is allowed); if it does not meet the conditions, activation is controlled (i.e., entry is not allowed). This can avoid the situation where the vehicle's power is insufficient when the second state information does not meet the entry conditions but entry is forced, thereby improving the user experience.
[0087] Optionally, the second configuration mode and the third configuration mode may further include an exit condition. When the second configuration mode and the third configuration mode are in the activated state, if the exit condition is met, the vehicle is controlled to exit the second configuration mode and the third configuration mode.
[0088] Specifically, after the vehicle enters the second configuration mode and the third configuration mode (that is, when the second configuration mode and the third configuration mode of the vehicle are in an activated state), the third state information of the vehicle can also be obtained, and then it is determined whether the third state information of the vehicle meets the exit conditions of the second configuration mode and the third configuration mode; if any item of the third state information of the vehicle meets the exit conditions, the control exits the second configuration mode and the third configuration mode; if none of the third state information of the vehicle meets the exit conditions, the control keeps the second configuration mode and the third configuration mode in an activated state.
[0089] For example, the third state information of the vehicle may include the speed state of the vehicle, the second ambient temperature state of the vehicle, the climbing state of the vehicle, the switch state of the second configuration mode of the vehicle, etc.
[0090] Exemplarily, it can be set that when the third state information of the vehicle meets any of the following exit conditions, the second configuration mode and the third configuration mode are exited, and when none of the following exit conditions are met, the second configuration mode and the third configuration mode are not exited.
[0091] Exemplarily, the exit conditions may include: being in a high-speed operating condition (for example, the vehicle speed is greater than a preset value, such as 135km / h; and the high-speed duration is greater than a preset value, such as 5s), a climbing condition (for example, the vehicle power demand is greater than a preset value, such as 60kW; and the duration is greater than a preset value, such as 30s), a rapid acceleration condition (for example, the vehicle power demand is greater than a preset value, such as 150kW; and the rapid acceleration duration is greater than a preset value, such as 5s; and the cumulative number of times within 60s is greater than a preset value, such as 3 times), the ambient temperature is less than or equal to a preset value (for example, 10°C), receiving a forced shutdown of the second configuration mode, etc. The above exit conditions are only examples and do not constitute a limitation to the present application scheme.
[0092] In an embodiment of the present application, it is possible to determine whether the third state information of the vehicle complies with the second configuration mode and the exit conditions of the third configuration mode based on the third state information of the vehicle, and exit when it complies, and not exit when it does not comply, so as to avoid scenarios with large power requirements or dynamic requirements, ensure the dynamic performance of the entire vehicle, and thus improve the user experience.
[0093] It should be understood that in actual applications, it is also possible to control the system to only enter the second configuration mode and not enter the third configuration mode. This application does not limit this.
[0094] A specific implementation method involved in the embodiment of the present application is exemplarily introduced below with reference to Figure 8. It should be understood that the process 800 shown in Figure 8 is only an example and does not constitute a limitation on the solution of the present application.
[0095] FIG8 is an example diagram of a vehicle control process according to an embodiment of the present application. As shown in FIG8 , the process 800 includes steps S801 to S811 , which are described below.
[0096] S801, power on the vehicle.
[0097] S802: Determine whether the user selects the second configuration mode or the third configuration mode. If the user selects the second configuration mode or the third configuration mode, continue to S803; if the user does not select the second configuration mode or the third configuration mode, execute S810 and maintain the first configuration mode.
[0098] S803: Determine whether the user confirms to enter.
[0099] Specifically, after the user selects the second or third configuration mode, a pop-up window appears on the vehicle's central control screen, prompting the user to confirm whether to enter the second or third configuration mode. If the user confirms again, the process continues with S804. If the user does not confirm or cancels the entry, the process continues with S810, maintaining the first configuration mode.
[0100] S804: Determine whether the entry conditions are met. Specifically, determine whether the entry conditions for the second configuration mode and the third configuration mode are met. If so, proceed to S805; if not, proceed to S810 and maintain the first configuration mode.
[0101] S805: Entering the second configuration mode and the third configuration mode. That is, the vehicle operates in the second configuration mode and the third configuration mode.
[0102] S806: Determine whether the system preset exit condition is met. If so, continue to execute S807; if not, continue to execute S805 to maintain the second configuration mode and the third configuration mode.
[0103] S807: Exit the second configuration mode and the third configuration mode, and enter the first configuration mode.
[0104] S808: Determine whether the user has chosen to exit voluntarily. If the user has chosen to exit voluntarily, proceed to step S809; if not, proceed to step S805 to maintain the second configuration mode and the third configuration mode.
[0105] Optionally, the user may actively choose to exit both the second configuration mode and the third configuration mode; or may actively choose to exit only the third configuration mode and maintain the second configuration mode.
[0106] S809: Exit according to the user's selection and enter the mode selected by the user. Specifically, if the user chooses to exit the third configuration mode, it means that the mode selected by the user is the second configuration mode; if the user chooses to exit the second configuration mode and the third configuration mode, it means that the mode selected by the user is the first configuration mode.
[0107] S810: Maintain the first configuration mode.
[0108] S811, the entire vehicle is powered off.
[0109] After the vehicle arrives at the destination, the entire vehicle needs to be powered off.
[0110] It should be noted that, based on the above step S805, if the exit conditions S806 and S808 are not met during the entire operation of the vehicle, then when arriving at the destination, power can be directly turned on based on the second configuration mode and the third configuration mode.
[0111] Optionally, when the vehicle is powered off, the vehicle can memorize the configuration mode before power off, so that the vehicle can continue to be controlled based on the configuration mode the next time the vehicle is powered on; or the vehicle may not memorize the configuration mode before power off, and directly control the vehicle based on the system default configuration mode the next time the vehicle is powered on. This embodiment of the present application does not limit this.

When the first configuration mode is activated, the range extender enters a first operating mode when the actual SOC value of the battery is less than or equal to a first threshold value. In the first operating mode, the range extender is configured to power the vehicle. When the second configuration mode is activated, the range extender enters the first operating mode when the actual SOC value of the battery is less than or equal to a second threshold value, where the second threshold value is less than the first threshold value. When the third configuration mode is activated, the range extender enters either the first operating mode or the second operating mode when the actual SOC value of the battery is less than or equal to a third threshold value.

[0118] Optionally, when the range extender is in the activated state, the processing module 920 may also be configured to control the activation of the vehicle to enter the second configuration mode; or control the activation of the vehicle to enter the second configuration mode and the third configuration mode.
