[0001] This application claims priority to the Chinese patent application No. 202211214762.2, filed on September 30, 2022, entitled "Control method of vehicle, control device of vehicle and vehicle", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the technical field of vehicles, and more particularly, to a control method of vehicle, a control device of vehicle and a vehicle. BACKGROUND

[0003] Compared with other electric vehicles, range extended electric vehicles have the advantages of simple configuration system, higher cruising range, lower cost, etc., and have been widely used in the field of electric vehicles. Range extended electric vehicles are configured with a range extender, which can provide additional electric energy to increase the cruising range of the electric vehicle. The engine (e.g., a fuel engine, etc.) is used to drive the generator to generate electricity, thereby increasing the cruising range of the vehicle.

[0004] The configurable modes of the conventional range extended electric vehicle include a hybrid electric vehicle (HEV) mode and an electric vehicle (EV) mode. However, improper switching of modes often brings a bad experience to users. Therefore, how to improve the experience of users using the range extended electric vehicle is a technical problem to be solved. SUMMARY

[0005] Embodiments of the present application provide a control method of vehicle, a control device of vehicle and a vehicle, which can improve the experience of users using the range extended electric vehicle.

[0006] In a first aspect, a control method of vehicle is provided, the vehicle comprising a battery and a range extender, configurable modes of the vehicle comprising a first configurable mode, a second configurable mode and a third configurable mode, when the first configurable mode is activated, the range extender enters a first working mode when an actual SOC value of the battery is less than or equal to a first threshold value; in the first working mode, the range extender is configured to power the vehicle; when the second configurable mode is activated, the range extender enters the first working mode when the 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 configurable mode is activated, the range extender enters the first working mode or a second working mode when the actual SOC value of the battery is less than or equal to a third threshold value, the third threshold value being less than or equal to the first threshold value and greater than the second threshold value, in the second working mode, the range extender is configured to idle.

[0007] The method comprises: when the second configuration mode and the third configuration mode are in an activated state, and when 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 comprising a power requirement of the vehicle; and determining, according to the first state information, that the range extender enters the first working mode or the second working mode.

[0008] The range extender entering the first working mode can be described as the range extender starting up, and the range extender starting up means that the range extender is configured to supply power to the vehicle; and the range extender entering the second working mode can be described as the range extender prestarting up, and in the prestarting up state, the range extender is configured to idle, so that the range extender is in a state of being ready to output (i.e. an immediate power generation state).

[0009] In the embodiments of the present application, when the second configuration mode and the third configuration mode are in an activated state, the first state 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 is determined to enter the first working mode or the second working mode according to the first state information. On the one hand, the SOC threshold value at which the range extender enters the first working mode can be reduced to the second threshold value (i.e. the starting threshold value of the range extender is reduced to the second threshold value), so as to realize 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 working mode or the second working mode according to the first state information of the vehicle, so as to avoid the situation that the vehicle is insufficient in power due to state information during the process of battery priority power supply, thereby improving the user experience of using the range-extended electric vehicle.

[0010] In combination with the first aspect, in some implementations of the first aspect, the determining, according to the first state information, that the range extender enters the first working mode or the second working mode comprises: if the output power of the battery is greater than or equal to the power requirement of the vehicle, controlling the range extender to work in the second working mode; and if the output power of the battery is less than the power requirement of the vehicle, controlling the range extender to work in the first working mode.

[0011] In the embodiments of the present application, the range extender can be controlled to work in the second working mode when the output power of the battery is greater than or equal to the power requirement of the vehicle, and the range extender can be controlled to work in the first working mode when the output power of the battery is less than the power requirement of the vehicle, so as to ensure the power level of the vehicle and improve the user experience.

[0012] In combination with the first aspect, in some implementations of the first aspect, the method further comprises: obtaining a user instruction, the user instruction being used to indicate that the second configuration mode and the third configuration mode are activated; and controlling, according to the user instruction, that the second configuration mode and the third configuration mode are activated.

[0013] In the embodiments of the present application, the second configuration mode and the third configuration mode can be activated 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 own will, thereby improving the user experience.

[0014] With reference to the first aspect, in some implementations of the first aspect, the method further includes: obtaining second state information of the vehicle, the second state information of the vehicle including a power-on state of the vehicle, a power state of the battery, and a first ambient temperature state in which the vehicle is located; determining whether the second state information of the vehicle meets an entering condition of the second configuration mode and the third configuration mode; if the second state information of the vehicle meets the entering condition, controlling to activate the second configuration mode and the third configuration mode; and if the second state information of the vehicle does not meet the entering condition, controlling to activate or maintain the first configuration mode.

[0015] In the embodiments of the present application, whether the second state information of the vehicle meets the entering condition of the second configuration mode and the third configuration mode can be determined based on the second state information of the vehicle, and the second configuration mode and the third configuration mode are activated when the entering condition is met, and are not activated when the entering condition is not met. Thus, the vehicle power deficiency can be avoided when the second state information does not meet the entering condition but is forced to enter, and the user experience can be improved.

[0016] With reference to the first aspect, in some 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 a speed state of the vehicle, a second ambient temperature state in which the vehicle is located, a climbing state of the vehicle, and a switch state of the second configuration mode of the vehicle; determining whether the third state information of the vehicle meets an exiting condition of the second configuration mode and the third configuration mode; if any of the third state information of the vehicle meets the exiting condition, controlling to exit the second configuration mode and the third configuration mode; and if none of the third state information of the vehicle meets the exiting condition, controlling to maintain the second configuration mode and the third configuration mode in the activated state.

[0017] In the embodiments of the present application, whether the third state information of the vehicle meets the exiting condition of the second configuration mode and the third configuration mode can be determined based on the third state information of the vehicle, and the second configuration mode and the third configuration mode are exited when the exiting condition is met, and are not exited when the exiting condition is not met, so as to avoid scenes with high power demand or high power performance demand, ensure the power performance of the vehicle, and improve the user experience.

[0019] In the embodiments of this application, when the range extender is working in the first working mode, the second configuration mode can also be activated; or, the second configuration mode and the third configuration mode can be activated. That is to say, when the range extender is working in the first working mode, it can also be forced to use battery power, thereby improving the user experience.

[0043] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.

[0044] The present application can be applied to a vehicle, which is a vehicle in a broad sense, and can be a traffic tool (such as a commercial vehicle, a passenger vehicle, a motorcycle, a flying vehicle, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), an agricultural device (such as a mower, a harvester, etc.), a recreational device, a toy vehicle, etc. The type of the vehicle is not limited in the embodiments of the present application. For example, the vehicle can be an airplane or a ship.

[0045] The embodiments of the present application can also be applied to other mobile devices in the fields of traffic, home, industry, construction, agriculture, entertainment, etc. The present application is not limited thereto. For ease of description, the vehicle is taken as an example for description in the following.

[0046] Figure 1 is an example of a functional block diagram of a vehicle 100 provided by an embodiment of the present application. As shown in Figure 1 The vehicle 100 can include a perception system 120, a display device 130 and a computing platform 150, wherein the perception system 120 can include several sensors for sensing environmental information about the surroundings of the mobile device 100, which can be road information, environmental temperature information, environmental brightness information, etc. For example, the perception system 120 can include a positioning system, which can be a global positioning system (GPS), a Beidou system or other positioning system, an inertial measurement unit (IMU), a laser radar, a millimeter wave radar, an ultrasonic radar and a camera device. The perception system 120 can also include sensors for monitoring the internal systems of the vehicle 100 (for example, an in-vehicle throttle depth, an in-vehicle air quality monitor, a fuel gauge, an oil temperature gauge, etc.).

[0047] The display device 130 is mainly divided into two categories, the first category is a vehicle-mounted display screen, and the second category is a projection display screen, such as a HUD. The vehicle-mounted display screen is a physical display screen and is an important component of the in-vehicle infotainment system. Multiple display screens can be arranged in the cabin, such as a digital instrument display screen, a center control screen, a display screen in front of a passenger (also referred to as a front passenger) at a co-driver position, a display screen in front of a left rear passenger, and a display screen in front of a right rear passenger, and even a vehicle window can be used as a display screen for display. The HUD, also known as a head-up display system, is mainly used to project vehicle speed, fuel level, navigation, and other information onto the windshield of the vehicle 100. After reflection by the windshield, a virtual image is formed at a certain distance in front of the driver's line of sight, so that the driver can see these information without lowering his head, thereby reducing the driver's line-of-sight shift time, avoiding pupil changes caused by the driver's line-of-sight shift, and improving driving safety and comfort. Among them, the HUD includes a combiner-HUD (C-HUD) system, a windshield-HUD (W-HUD) system, and an augmented reality-HUD (AR-HUD) system. At present, the traditional HUD mainly displays vehicle instrument information such as vehicle speed and fuel level; compared with the traditional HUD, the AR-HUD has a larger field of view and a farther screen, can fuse AR images with real environment information, enhances the driver's acquisition of road information, and realizes AR navigation, adaptive cruise control, lane departure warning, and other functions.

[0048] Some or all functions of the vehicle 100 can be controlled by the computing platform 150. The computing platform 150 can include one or more processors, such as processors 151 through 15n (n is a positive integer), which are circuits with the capability of processing signals. In one implementation, the processors can be circuits with the capability of reading and running instructions, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a kind of microprocessor), a digital signal processor (DSP), and the like. In another implementation, the processors can be circuits with the capability of implementing certain functions through a fixed or reconfigurable logical relationship of hardware circuits, such as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD) implemented hardware circuit, such as a field programmable gate array (FPGA). In the reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit. It can be understood that the processor loads instructions to implement the functions of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as a kind of ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), and the like. In addition, the computing platform 150 can also include a memory for storing instructions, and some or all of the processors 151 through 15n can call the instructions in the memory and execute the instructions to implement corresponding functions.

[0049] Figure 2 is an example diagram of a vehicle cabin scene provided by an embodiment of the present application. One or more cameras can be installed inside or outside the cabin to capture images inside or outside the cabin, such as a camera of a driver monitoring system (DMS), a camera of a cabin monitoring system (CMS), and a camera of a dashcam, Figure 2Taking a camera arranged at the A-pillar as an example. Among them, the camera for capturing the inside and outside of the cabin can be the same camera or different cameras. In addition, a vehicle display screen is arranged in the cabin, Figure 2 Taking a display screen arranged in the center control region as an example. Optionally, one or more of driving required information, audio and video entertainment information, vehicle configuration information, and the like can be displayed through the vehicle display screen; the vehicle display screen can also be used to realize human-vehicle interaction, for example, a user can click a related icon or input an instruction on the display screen to control the vehicle; for another example, the vehicle can pop up a message through the vehicle display screen to remind the user, or the vehicle can display operation options through the vehicle display screen for the user to select according to actual needs. It should be understood that the position of the camera in the cabin for collecting image information in the embodiments of the present application is not specifically limited. The camera can be located Figure 2 on the A-pillar as shown, can be located below the steering wheel, can be located on the B-pillar, or can be located near the rearview mirror, etc.

[0050] The background technology involved in the scheme of the present application will be briefly introduced below taking a range-extended electric vehicle as an example.

[0051] The range-extended electric vehicle includes a battery and a range extender. The range extender can provide additional electrical energy to increase the driving range of the vehicle. The range extender is essentially a combination of an engine (for example, a fuel engine, etc.) and a generator, which is used to drive the generator to generate electricity, thereby increasing the driving range of the vehicle. In order to reduce the cost of the vehicle, the capacity of the battery in the range-extended electric vehicle is generally small, so that the battery power is low at a low SOC (for example, below 20%), resulting in poor power performance when the battery is powered.

[0052] The configurable modes of the traditional range-extended electric vehicle include HEV mode and EV mode. When the HEV mode is activated, the vehicle system usually sets a threshold in advance, and uses battery power when the actual SOC value of the battery is greater than or equal to the threshold; when the actual SOC value of the battery is less than the threshold, the range extender is started to drive the generator with the engine. In order to ensure the power performance of the whole vehicle, the threshold set in the traditional scheme is usually high (for example, 20%), which means that the range extender is started forcibly when the actual SOC value of the battery is high, resulting in that the user cannot continue to use the remaining battery power, which causes a poor experience for users who are sensitive to the cost of using the vehicle. For example, if the user is currently driving in a scenario that does not require high power, the user can reach the destination based on the remaining 20% of the battery power and then charge through a charging pile, but due to the threshold setting of the system, the power supply is automatically switched to the range extender. The use of the range extender requires fuel, which increases the cost of using the vehicle, and increases the noise, vibration, and harshness (NVH) of the whole vehicle, resulting in a poor user experience.

[0053] EV mode, i.e. pure electric mode, when the EV mode is activated, the start threshold of the range extender is lower (for example, as low as 10%), therefore, the cost and noise sensitive users can choose the EV mode, so that the battery power supply can continue even when the actual SOC value of the battery is lower than the above-mentioned threshold of 20%. However, based on this mode, when the actual SOC value is between 10% and 20%, the vehicle power is insufficient, which has no effect on general urban roads, but in the scene of high speed, climbing, sudden acceleration, low temperature, etc., the battery power supply cannot provide enough power to drive the vehicle to run, resulting in poor user experience.

[0054] Therefore, based on this, the embodiment of the present application provides a control method of a vehicle, which can use battery power supply preferentially while not affecting the vehicle power, thereby improving the user experience.

[0055] Before introducing the control method provided by the embodiment 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. The three configuration modes are introduced as follows.

[0056] When the first configuration mode is activated, the range extender enters the first working mode when the actual SOC value of the battery is less than or equal to the first threshold, and in the first working mode, the range extender is configured to supply power to 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 working mode to supply power to the vehicle (specifically, the engine is used to drive the generator to supply power to the vehicle). The first configuration mode can also be understood as the above-mentioned HEV mode, and the first threshold can be 20%, for example. It should be noted that the above-mentioned "when the first configuration mode is activated" can also be described as "in the first configuration mode" or "when entering the first configuration mode"; "the range extender enters the first working mode" can also be described as "the range extender starts", which means that the range extender is in the state of supplying power to the vehicle, and the embodiment of the present application does not distinguish between them. It should be understood that the range extender supplying power to the vehicle can be understood as the range extender supplying power to the vehicle during vehicle running to provide power for the vehicle, or can be understood as the range extender charging the battery in the vehicle.

[0057] 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, and the second threshold value is less than the first threshold value. Specifically, when the second configuration mode is activated, the battery is used to supply power when the actual SOC value of the battery is greater than the second threshold value; the range extender enters the first operating mode to supply power to the vehicle when the actual SOC value of the battery is less than or equal to the second threshold value. Since the second threshold value is less than the first threshold value, the battery can still be used to supply power when the actual SOC value of the battery is in the interval between the first threshold value and the second threshold value. The second configuration mode can also be understood as the EV mode described above. Based on the second configuration mode, the SOC threshold value (i.e., the start threshold value of the range extender) at which the range extender enters the first operating mode is lower, and the battery can be preferentially used to supply power. The second threshold value may, for example, be 10%. It should 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 the second configuration mode is entered", and the embodiments of the present application do not distinguish between them.

[0058] 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, and the range extender is configured to idle in the second operating mode. The third threshold value is less than or equal to the first threshold value and greater than the second threshold value, and the second threshold value may, for example, be 15%. That is, the range extender can enter the first operating mode and the second operating mode when the actual SOC value of the battery is less than or equal to the third threshold value. The "range extender enters the second operating mode" can also be described as "range extender pre-start" or "engine pre-start". The essence of the start of the range extender is that the range extender (or engine) is configured to idle, and the range extender is in a state ready to output through idling, i.e., the range extender is pre-prepared for the preparation work before the formal operating state. The third configuration mode can also be understood as a pre-start range extender mode. It should be noted that the above-mentioned "when the third configuration mode is activated" can also be described as "in the third configuration mode" or "when the third configuration mode is entered", and the embodiments of the present application do not distinguish between them.

[0059] The first threshold, the second threshold and the third threshold are only examples, and in actual operation, they need to be confirmed in combination with specific conditions, and the present application does not limit this. For example, in the case where the first threshold is 20% and the second threshold is 10%, if the actual SOC value of the battery is between 15% and 20%, even if the battery is used for power supply, it will not affect or slightly affect the power performance of the vehicle in the scenarios of high speed, climbing, sudden acceleration, low temperature environment, etc., but when it is lower than 15%, it will seriously affect the power performance of the vehicle in the scenarios of high speed, climbing, sudden acceleration, low temperature environment, etc., then it can be set that when it is lower than 15%, the range extender can be pre-started, so that the range extender enters the state of preparing to output, so that when the scenarios of high speed, climbing, sudden acceleration, low temperature environment, etc. are encountered, the range extender can immediately enter the power generation state.

[0060] Based on the above three configuration modes, the control method of the vehicle provided by the embodiments of the present application will be described in detail below. Figure 3 The control method of the vehicle provided by the embodiments of the present application will be described in detail below. Figure 3 is an example diagram of a control method of a vehicle provided by the embodiments of the present application. It should be understood that the method 300 can be executed by one or more processors in the computing platform 150 described above. As shown in Figure 3 , the method 300 includes steps S310 and S320, which will be described in detail below.

[0061] Optionally, before executing the method 300, the second configuration mode and the third configuration mode can be activated, that is, controlled to enter the second configuration mode and the third configuration mode.

[0062] In an implementation mode, the vehicle can be controlled to enter the second configuration mode and the third configuration mode based on user operation. Specifically, the user can send an instruction to the vehicle, which is used to instruct to activate (that is, control the vehicle to enter) the second configuration mode and the third configuration mode; then the vehicle obtains the user instruction and controls to activate (that is, control the vehicle to enter) the second configuration mode and the third configuration mode according to the user instruction.

[0063] In actual operation, the entering icons of the second configuration mode and the third configuration mode (see icons 1 and 2 in Figure 4 ) can be set on the vehicle display screen in the vehicle cabin, and the user can send an instruction to the vehicle by clicking the entering icons of the second configuration mode and the third configuration mode on the vehicle display screen to instruct the vehicle to enter the second configuration mode and the third configuration mode. Alternatively, the user can click the "setting" icon on the vehicle display screen to select the mode of the vehicle in the vehicle setting system to instruct the vehicle to enter the second configuration mode and the third configuration mode. Alternatively, the entering buttons of the second configuration mode and the third configuration mode (see Figure 5(Buttons 1 and 2 in the image) Users can send commands to the vehicle to enter the second and third configuration modes by clicking or toggling the enter buttons. Alternatively, users can send voice commands to the vehicle to enter the second and third configuration modes; for example, a user can send the voice command, "Interactive assistant, please enter the second and third configuration modes!" (see [link]). Figure 6 This is used 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 solution presented in this application.

[0064] The second and third configuration modes described above can be accessed via a single icon or button; that is, clicking the icon or button will control entry into either the second or third configuration mode. Alternatively, two icons or two buttons can be used to control entry into the second and third configuration modes respectively; that is, the 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.

[0065] Optionally, after the vehicle receives the user's instruction, it can remind the user to confirm again whether they need to enter the second and third configuration modes via an in-vehicle display screen or voice prompt (see [link]). Figure 7 It should be understood that secondary confirmation can prevent users from accidentally entering the second and third configuration modes.

[0066] Optionally, the above-mentioned user sending instructions to the vehicle can be initiated by the user, or it can be initiated by the user after the vehicle has made a reminder or selection (for example, after the vehicle is powered on, it can consult the user through human-vehicle interaction whether to enter the second configuration mode and the third configuration mode; or, 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 start or has already started, allowing the user to operate according to their own wishes).

[0067] In another implementation, the vehicle can intelligently control the entry into the second and third configuration modes. For example, the vehicle can spontaneously enter the second and third configuration modes based on the current scenario and vehicle status; or the vehicle can be set to prioritize the activation of the second and third configuration modes, which is not limited in this application.

[0068] Optionally, when the range extender works in the first working mode (i.e. in the starting case), the second configuration mode can also be controlled to be activated; or the second configuration mode and the third configuration mode are controlled to 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), so as to enter the battery-powered state. That is to say, in the starting case of the range extender, the battery-powered state can also be forced to be used, so as to improve the experience of the user.

[0069] In S310, first state information of the vehicle is acquired. Specifically, when the second configuration mode and the third configuration mode are in the activated state, and the SOC value of the battery is less than or equal to the third threshold value, the first state information of the vehicle can be acquired.

[0070] Optionally, the first state information can include a power demand state of the vehicle. It should be understood that when the vehicle is in different scenes, different power demands can be corresponded. For example, in the scenes of high speed, climbing, sudden acceleration, etc., the power demand is high, and correspondingly, the power performance requirement of the vehicle is high; in the scene of smooth driving on urban traffic road, the power demand is low, and correspondingly, the power performance requirement of the vehicle is low.

[0071] In actual operation, the size of the power demand can be distinguished based on the accelerator depth and the holding time at the depth. Specifically, when the accelerator depth is large and the duration is long, it is considered that the current power demand is large; otherwise, it is considered that the current power demand is small.

[0072] Optionally, the first state information can also include information such as an ambient temperature state of the vehicle, which is not limited.

[0073] In S320, it is determined 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 that it is determined whether the range extender needs to be in the pre-starting state or the output state according to the first state information of the vehicle. Or it can be understood that it is determined whether the range extender enters the output state from the pre-starting 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, the range extender is controlled to enter the second working mode first, and if it is determined again according to the updated first state information during the subsequent vehicle driving that the range extender needs to enter the first working mode, the range extender can be controlled to switch from the second working mode to the first working mode (i.e. from the pre-starting state to the output state).

[0074] In the embodiments of the present application, when the second configuration mode and the third configuration mode are in the activated state, the first state information of the vehicle can be acquired when the SOC value of the battery is less than or equal to the third threshold value, and the first working mode or the second working mode of the range extender is determined according to the first state information. On the one hand, the SOC threshold value of the range extender entering the first working mode can be reduced to the second threshold value (i.e., the start threshold value of the range extender is reduced to the second threshold value), so as to realize the 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 first working mode or the second working mode of the range extender can be determined according to the first state information of the vehicle, so as to avoid the situation that the vehicle power is insufficient due to the state information in the process of the battery priority power supply, thereby improving the user experience of using the range extender electric vehicle.

[0075] Optionally, the range extender can be controlled to work in the first working mode or switched from the second working mode to the first working mode (i.e., switched from the pre-start state to the output state) when the power demand of the vehicle is greater than or equal to the preset value. When the power demand of the vehicle is less than the preset value, the range extender is controlled to work in the second working mode (i.e., in the pre-start state).

[0076] Optionally, the range extender can be controlled to work in the second working mode (i.e., in the pre-start state) when the output power of the battery is greater than or equal to the power demand of the vehicle; and the range extender is controlled to work in the first working mode or switched from the second working mode to the first working mode (i.e., switched from the pre-start state to the output state) when the output power of the battery is less than the power demand of the vehicle, so as to ensure the power level of the vehicle and improve the user experience. It should be understood that the output power of the battery is affected by the battery power and the temperature of the environment. Generally, the lower the battery power is, the lower the output power of the battery is.

[0077] Optionally, in actual operation, the range extender can also be controlled to enter the output state from the pre-start state when the accelerator depth is greater than the preset value (for example, 70%) and the duration is greater than the preset value (for example, 3s), and vice versa.

[0078] It should be understood that the engine will have a time delay when starting, which can be up to tens of seconds. If the actual SOC value of the battery is less than or equal to the third threshold value, and the starting of the range extender is started in a scene with high power demand, the vehicle power will be insufficient during the starting process, resulting in poor user experience. In the scheme of the present application, if there is no high-power scene when the actual SOC value of the battery is less than or equal to the third threshold value, the range extender can be pre-started, and whether the range extender needs to enter the output state (i.e., whether it enters the output state from the pre-started state) is determined based on the first state information of the vehicle. When a high-power scene is encountered, the range extender can directly enter the output state (i.e., the power generation state), avoiding the situation of insufficient vehicle power caused by the delay of the range extender output.

[0079] It should be understood that the purpose of pre-starting the range extender is to make the temperature of the cooling medium of the engine reach a preset value (for example, 70℃), based on which the range extender can be in a state ready for output. Therefore, for the pre-starting of the range extender, if the actual temperature of the cooling medium of the engine in the range extender is less than the preset value (for example, 70℃), 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 cooling medium of the engine has reached the preset value, the engine does not need to idle, and the range extender can also be in a state ready for output. Therefore, whether the engine needs to idle during pre-starting can be determined based on the temperature of the cooling medium.

[0080] Optionally, the second configuration mode and the third configuration mode can also include an entry condition. The second configuration mode and the third configuration mode can be activated only when the entry condition is met.

[0081] 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 condition of the second configuration mode and the third configuration mode; if the second state information of the vehicle meets the entry condition, the second configuration mode and the third configuration mode are activated (i.e., the vehicle is controlled to enter); if the second state information of the vehicle does not meet the entry condition, the first configuration mode is activated or maintained (i.e., the vehicle is controlled to enter).

[0082] Optionally, the second state information of the vehicle can include the power-on state of the vehicle, the state of charge of the battery, and the first ambient temperature state in which the vehicle is located, etc.

[0083] For example, it can be set that the entry condition is 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 in which the vehicle is located is greater than a preset value (for example, 10℃), and the entry condition is not met when any of the above conditions is not met.

[0084] Optionally, the second state information of the vehicle listed above is only an example, and more or less state information can be included in practice, which needs to be determined in combination with the actual driving scene of the vehicle, and the present application does not limit this. Based on this, the entering condition can also be adjusted with 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, and correspondingly, the entering condition can also include that the vehicle driving speed is lower than a preset value, and the predicted high-speed driving duration is shorter than a preset value, so as to meet the entering condition.

[0085] In the embodiments of the present application, whether the second state information of the vehicle meets the entering condition of the second configuration mode and the third configuration mode can be determined based on the second state information of the vehicle, and when it meets, the activation (i.e. entering) is controlled, and when it does not meet, the activation (i.e. not entering) is not controlled. Thus, the situation of insufficient vehicle power can be avoided when the second state information does not meet the entering condition but is forced to enter, and thus the user experience can be improved.

[0086] Optionally, the second configuration mode and the third configuration mode can also include an exit condition, and 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.

[0087] Specifically, after the vehicle enters the second configuration mode and the third configuration mode (i.e. when the second configuration mode and the third configuration mode of the vehicle are in the activated state), the third state information of the vehicle can be obtained, and then it is determined whether the third state information of the vehicle meets the exit condition of the second configuration mode and the third configuration mode; if any of the third state information of the vehicle meets the exit condition, the second configuration mode and the third configuration mode are controlled to exit; if none of the third state information of the vehicle meets the exit condition, the second configuration mode and the third configuration mode are controlled to remain in the activated state.

[0088] Exemplarily, the third state information of the vehicle can include the speed state of the vehicle, the second ambient temperature state in which the vehicle is located, the climbing state of the vehicle, the switch state of the second configuration mode of the vehicle, etc.

[0089] Exemplarily, the second configuration mode and the third configuration mode can be exited when any of the following exit conditions is met, and not exited when none of the following exit conditions is met.

[0090] Exemplarily, the exit condition may include, for example, being in a high-speed working condition (e.g., a vehicle speed is greater than a preset value, such as 135 km / h; and a high-speed duration is greater than a preset value, such as 5 s), a climbing working condition (e.g., a vehicle power demand is greater than a preset value, such as 60 kW; and a duration is greater than a preset value, such as 30 s), an urgent acceleration working condition (e.g., a vehicle power demand is greater than a preset value, such as 150 kW; and an urgent acceleration duration is greater than a preset value, such as 5 s; and a cumulative number within 60 s is greater than a preset value, such as 3 times), an ambient temperature is less than or equal to a preset value (e.g., 10℃), receiving a forced closing of the second configuration mode, and the like. The above exit conditions are merely examples and do not constitute a limitation on the scheme of the present application.

[0091] In the embodiments of the present application, whether the third state information of the vehicle meets the exit condition of the second configuration mode and the third configuration mode can be determined based on the third state information of the vehicle, and the exit condition is exited when it is met, and is not exited when it is not met, so as to avoid a scene with a greater power demand or dynamic demand, and ensure the dynamic of the vehicle, thereby improving the experience of the user.

[0092] It should be understood that in actual application, only the second configuration mode can be entered, and the third configuration mode is not entered, which is not limited by the present application.

[0093] The following will be described in combination with Figure 8 A specific implementation mode related to the embodiments of the present application is exemplarily introduced. It should be understood that Figure 8 The flow 800 shown is merely an example and does not constitute a limitation on the scheme of the present application.

[0094] Figure 8 is an example of a control flow of a vehicle provided by the embodiments of the present application. As Figure 8 shown, the flow 800 includes steps S801 to S811, which will be introduced as follows.

[0095] S801, the vehicle is powered on.

[0096] S802, it is judged whether the user selects the second configuration mode and the third configuration mode. If the user selects the second configuration mode and the third configuration mode, S803 is continued to be executed; if the user does not select the second configuration mode and the third configuration mode, S810 is executed to maintain the first configuration mode.

[0097] S803, it is judged whether the user confirms to enter.

[0098] Specifically, after the user selects the second configuration mode and the third configuration mode, the user is prompted by a pop-up window of the vehicle-mounted central control screen to confirm again whether to enter the second configuration mode and the third configuration mode. If the user confirms again, S804 is continued; if the user does not confirm or cancels the entry, S810 is executed to maintain the first configuration mode.

[0099] S804, determining whether the entering condition is met. Specifically, it is determined whether the entering condition of the second configuration mode and the third configuration mode is met. If yes, S805 is continued; if no, S810 is executed to maintain the first configuration mode.

[0100] S805, entering the second configuration mode and the third configuration mode. That is, the vehicle runs in the second configuration mode and the third configuration mode.

[0101] S806, determining whether the system preset exit condition is met. If yes, S807 is continued; if no, S805 is continued to maintain the second configuration mode and the third configuration mode.

[0102] S807, exiting the second configuration mode and the third configuration mode and entering the first configuration mode.

[0103] S808, determining whether the user actively selects to exit. If the user selects to actively exit, S809 is continued; if no, S805 is continued to maintain the second configuration mode and the third configuration mode.

[0104] Optionally, the user can actively select to exit the second configuration mode and the third configuration mode; or can actively select to exit only the third configuration mode and maintain the second configuration mode.

[0105] S809, exiting according to the user selection and entering the mode selected by the user. Specifically, if the user selects to exit the third configuration mode, it means that the mode selected by the user is the second configuration mode; if the user selects 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.

[0106] S810, maintaining the first configuration mode.

[0107] S811, powering off the whole vehicle.

[0108] After the vehicle arrives at the destination, the whole vehicle needs to be powered off.

[0109] It should be noted that, based on the above step S805, if the exit conditions S806 and S808 are not met during the whole running process of the vehicle, the vehicle can be directly powered off based on the second configuration mode and the third configuration mode when arriving at the destination.

[0110] Optionally, when the whole vehicle is powered off, the vehicle can memorize the configuration mode in which the vehicle is before being powered off, so that the vehicle can continue to be controlled based on the configuration mode next time the whole vehicle is powered on; or the vehicle can also not memorize the configuration mode in which the vehicle is before being powered off, and directly control the vehicle based on the default configuration mode of the system next time the whole vehicle is powered on, and the embodiments of the application do not limit this.
