Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a vehicle control method and a vehicle in the field of vehicle technology. Background Technology

[0002] The dual-mode hybrid electric power consumption reduction is an intelligent energy management strategy in hybrid electric vehicles. It aims to reduce the rate of fuel consumption and the rate of depletion of the power battery's charge (State of Charge, SOC) by controlling the switching between fuel and electricity (i.e., fuel-electric switching), thereby effectively reducing the energy consumption of the power battery and engine and improving driving range.

[0003] Currently, the traditional hybrid electric vehicle switching mode relies on fixed thresholds (such as fixed SOC threshold, fixed vehicle speed threshold, etc.) to control the switching between hybrid and electric power. However, this method makes the switching between hybrid and electric power inflexible, resulting in higher energy consumption for the whole vehicle.

[0004] Therefore, when the dual-mode of reducing both oil and electricity consumption is activated, how to effectively balance the energy consumption of oil and electricity in order to reduce the overall energy consumption of the vehicle is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides a vehicle control method and a vehicle, which can effectively balance the energy consumption of both oil and electricity and reduce the overall energy consumption of the vehicle when the dual-mode of reducing oil and electricity is activated.

[0006] Firstly, a vehicle control method is provided, comprising: when the vehicle's dual-mode power-off is activated, acquiring the vehicle's mileage parameters and the power battery's charge parameters; determining, based on the vehicle's mileage parameters and the power battery's charge parameters, whether a preset activation condition for an intermittent mode is met; if the preset activation condition is met, activating the intermittent mode; and when the intermittent mode is activated, controlling the engine to stop and supplying power to the drive motor in the vehicle through the power battery, so that the drive motor drives the vehicle.

[0007] In the embodiments of this application, when the vehicle's dual-mode power-fuel switching is activated, the vehicle's mileage parameters and the power battery's charge parameters are obtained; based on the vehicle's mileage parameters and the power battery's charge parameters, it is determined whether the preset activation conditions for the intermittent mode are met; if the preset activation conditions are met, the intermittent mode is activated; when the intermittent mode is activated, the engine is shut down, and the power battery supplies power to the drive motor in the vehicle, so that the drive motor drives the vehicle. Compared with the traditional dual-mode power-fuel switching that relies on a fixed threshold to control the switching between oil and electricity, this solution can shut down the engine and supply power to the drive motor in the vehicle through the power battery when the intermittent mode is activated, so that the drive motor drives the vehicle; and the solution determines whether the preset activation conditions for the intermittent mode are met based on the mileage parameters and the power battery's charge parameters, without relying on a fixed threshold to control the switching between oil and electricity; based on this, this solution can effectively balance the energy consumption of oil and electricity and reduce the overall vehicle energy consumption when the dual-mode power-fuel switching is activated, while the intermittent mode is activated.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the mileage parameters include: current cumulative mileage and latched mileage; the battery power parameters include: latched battery power and current actual battery power; obtaining the vehicle's mileage parameters and the power battery power parameters includes: if preset latching conditions are met, then using the actual battery power when the preset latching conditions are met as the latched battery power, and using the vehicle's cumulative mileage when the preset latching conditions are met as the latched mileage; during vehicle operation, obtaining the current actual battery power and the vehicle's current cumulative mileage.

[0009] In the embodiments of this application, by detecting whether the current driving condition of the vehicle meets the preset latching conditions, and using the actual battery level when the preset latching conditions are met as the latched battery level and the cumulative driving mileage as the latched mileage, a benchmark value is provided for whether to activate the intermittent mode in the future, thereby improving the reliability of activating the intermittent mode.

[0010] In combination with the first aspect and the above implementation methods, in some implementation methods of the first aspect, it is determined whether the preset activation conditions of the intermittent mode are met based on the vehicle's mileage parameters and the power battery's charge parameters. This includes: subtracting the latched charge from the current actual charge to obtain the charge difference; subtracting the latched mileage from the current cumulative mileage to obtain the mileage difference; and determining whether the preset activation conditions of the intermittent mode are met based on the charge difference and the mileage difference.

[0011] In the embodiments of this application, the timing of vehicle activation of intermittent mode can be accurately detected by the difference in battery power and the difference in mileage, thereby achieving the optimal dynamic balance of fuel and electricity consumption in the dual-mode of reduced fuel and electricity consumption and improving the vehicle's driving range.

[0012] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, determining whether the preset activation conditions of the intermittent mode are met based on the difference in battery power and the difference in mileage includes: if the difference in mileage is less than or equal to a preset mileage threshold and the difference in battery power is greater than or equal to a first preset battery power threshold, then the preset activation conditions of the intermittent mode are met; if the difference in mileage is greater than a preset mileage threshold and the difference in battery power is greater than or equal to a second preset battery power threshold and less than zero, then the preset activation conditions of the intermittent mode are met, where the first preset battery power threshold is a positive value and the second preset battery power threshold is a negative value.

[0013] In the embodiments of this application, by detecting whether the power difference is greater than or equal to a first preset power threshold, and whether the power difference is greater than or equal to a second preset power threshold and less than zero, it is possible to detect whether the current actual power level is abnormally rising or falling, or other abnormal power level changes. In the case of abnormal power level changes, an intermittent mode is activated to prioritize the discharge of the power battery, so as to dynamically adjust the power battery level and reduce fuel consumption, thereby effectively balancing fuel and electricity consumption to reduce the overall vehicle energy consumption.

[0014] In combination with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the preset latching conditions include: the dual-mode power reduction is changed from never being activated to being activated; or, the dual-mode power reduction is activated and the intermittent mode changes from being activated to being inactive; or, when the intermittent mode is activated, the difference between the current actual power and the latched power is greater than a third preset power threshold; or, when the intermittent mode is not activated, the difference between the current actual power and the latched power is less than a fourth preset power threshold.

[0015] In the embodiments of this application, by latching the current actual charge of the power battery and the cumulative mileage of the vehicle under various preset latching conditions, the latched charge and latched mileage of the latching mechanism can be calibrated in a timely manner, thereby improving the accuracy of the activation and exit timing of the trigger detection intermittent mode.

[0016] In conjunction with the first aspect and the above-described implementation methods, in some implementation methods of the first aspect, the method provided by the embodiments of this application further includes: when the dual-power mode is activated, obtaining the current actual power level and the current target power level of the power battery; determining the virtual target power level based on the current actual power level; and controlling the vehicle to operate in the dual-power mode based on the virtual target power level and the current target power level.

[0017] In the embodiments of this application, by determining a virtual target battery level, the target battery level of the vehicle can be further corrected when the dual-mode of reducing power consumption is activated. Then, the actual battery level can be adjusted based on the corrected target battery level to effectively balance the energy consumption of power consumption and reduce the overall energy consumption of the vehicle.

[0018] In combination with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the virtual target power is determined based on the current actual power, including: detecting the current state of the intermittent mode; if the current state is active, subtracting the current actual power from the first target value to obtain the virtual target power; if the current state is inactive, adding the current actual power to the second target value to obtain the virtual target power; wherein the first target value and the second target value are determined by the current ambient temperature and the engine coolant temperature.

[0019] In the embodiments of this application, by combining the current state of the intermittent mode, and then calculating the virtual target power in both the active and inactive states, the target power of the power battery can be further precisely adjusted, thereby effectively taking into account the energy consumption of both gasoline and electric vehicles and reducing the overall vehicle energy consumption.

[0020] Combining the first aspect and the above implementation methods, in some implementation methods of the first aspect, the vehicle is controlled to operate in a dual-power mode based on the virtual target power level and the current target power level, including: comparing the virtual target power level and the current target power level; if the virtual target power level is greater than the current target power level, the vehicle is controlled to operate in a dual-power mode with the virtual target power level; if the virtual target power level is less than or equal to the current target power level, the vehicle is controlled to operate in a dual-power mode with the current target power level.

[0021] In the embodiments of this application, by comparing the virtual target battery level and the current target battery level, it is determined whether to control the vehicle to operate in the dual-mode of reducing both oil and electricity based on the virtual target battery level or the current target battery level. This further enables the effective consideration of both oil and electricity energy consumption and reduces the overall vehicle energy consumption when the dual-mode of reducing both oil and electricity is activated.

[0022] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, the method provided by the embodiments of this application further includes: when the intermittent mode is activated, increasing the engine starting power threshold from the current power threshold to a first target power threshold; and when the intermittent mode is not activated, decreasing the engine starting power threshold from the current power threshold to a second target power threshold.

[0023] In the embodiments of this application, by dynamically adjusting the engine's starting power threshold, the ease of starting the engine can be controlled, thereby effectively balancing the energy consumption of both oil and electricity in the dual-mode of reducing oil and electricity consumption and lowering the overall vehicle energy consumption.

[0024] Secondly, a vehicle control device is provided, the control device comprising:

[0025] The acquisition module is used to acquire the vehicle's mileage parameters and the power battery's charge parameters when the vehicle's dual-mode (oil and electric) is activated.

[0026] The determination module is used to determine whether the preset activation conditions of the intermittent mode are met based on the vehicle's mileage parameters and the power battery's charge parameters.

[0027] The activation module is used to activate the intermittent mode when preset activation conditions are met.

[0028] The control module is used to stop the engine when the intermittent mode is activated, and to power the drive motor in the vehicle through the power battery so that the drive motor can drive the vehicle.

[0029] As one possible implementation, the acquisition module is specifically used to: if the preset latching conditions are met, use the actual charge of the power battery when the preset latching conditions are met as the latched charge, and use the cumulative mileage of the vehicle when the preset latching conditions are met as the latched mileage; during the vehicle's operation, acquire the current actual charge of the power battery and the current cumulative mileage of the vehicle.

[0030] As one possible implementation, a determination module is specifically used to subtract the latched power from the current actual power to obtain the power difference; subtract the latched mileage from the current cumulative mileage to obtain the mileage difference; and determine whether the preset activation conditions of the intermittent mode are met based on the power difference and the mileage difference.

[0031] As one possible implementation, the determining module is specifically used to determine that the preset activation condition of the intermittent mode is met if the mileage difference is less than or equal to a preset mileage threshold and the battery difference is greater than or equal to a first preset battery threshold; if the mileage difference is greater than a preset mileage threshold and the battery difference is greater than or equal to a second preset battery threshold and less than zero, then the preset activation condition of the intermittent mode is met, where the first preset battery threshold is a positive value and the second preset battery threshold is a negative value.

[0032] As one possible implementation, the acquisition module is also used to acquire the current actual charge and the current target charge of the power battery when the dual-power mode is activated; the determination module is also used to determine the virtual target charge based on the current actual charge; and the control module is also used to control the vehicle to operate in the dual-power mode based on the virtual target charge and the current target charge.

[0033] As one possible implementation, a determination module is used to detect the current state of the intermittent mode; if the current state is active, the current actual power is subtracted from the first target value to obtain the virtual target power; if the current state is inactive, the current actual power is added to the second target value to obtain the virtual target power; wherein, the first target value and the second target value are determined by the current ambient temperature and the engine coolant temperature.

[0034] As one possible implementation, the control module is specifically used to: compare the virtual target battery level with the current target battery level; if the virtual target battery level is greater than the current target battery level, control the vehicle to operate in a dual-power mode with reduced power consumption at the virtual target battery level; if the virtual target battery level is less than or equal to the current target battery level, control the vehicle to operate in a dual-power mode with reduced power consumption at the current target battery level.

[0035] As one possible implementation, the determining module is also used to increase the engine's starting power threshold from the current power threshold to a first target power threshold when the intermittent mode is activated; and to decrease the engine's starting power threshold from the current power threshold to a second target power threshold when the intermittent mode is not activated.

[0036] Thirdly, a vehicle is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the methods of the first aspect or any possible implementation thereof.

[0038] Fifthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof. Attached Figure Description

[0043] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0044] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0045] The dual-mode hybrid electric power consumption is an intelligent energy management strategy in hybrid electric vehicles. It aims to reduce the rate of fuel consumption and the rate of depletion of the power battery's charge by controlling the switching between fuel and electricity (i.e., the switching between fuel and electricity), thereby effectively reducing the energy consumption of the power battery and the engine and improving the driving range.

[0046] For example, such as Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for a dual-mode (fuel and electricity consumption reduction) provided in an embodiment of this application. Compared to when the dual-mode is not activated in vehicle 110, when the dual-mode is activated, the rate at which the battery charge and remaining fuel level in vehicle 110 decrease will decrease on the display interface 120, thereby reducing both fuel and electricity consumption to extend the vehicle's range.

[0047] Currently, the traditional hybrid electric vehicle switching mode relies on fixed thresholds (such as fixed SOC threshold, fixed vehicle speed threshold, etc.) to control the switching between hybrid and electric power. However, this method makes the switching between hybrid and electric power inflexible, resulting in higher energy consumption for the whole vehicle.

[0048] Therefore, when the dual-mode of reducing fuel consumption by both fuel and electricity is activated, how to effectively balance the energy consumption of fuel and electricity in order to reduce the overall energy consumption of the vehicle is a technical problem that urgently needs to be solved.

[0049] In view of this, embodiments of this application provide a vehicle control method and a vehicle. This method can control the engine to stop and drive the vehicle through the power battery when the intermittent mode is activated. The solution determines whether the preset activation conditions of the intermittent mode are met based on mileage parameters and power battery charge parameters, without relying on a fixed threshold to control the switching between oil and electricity. Based on this, this solution can dynamically control the engine to stop and supply power to the drive motor in the vehicle through the power battery when the intermittent mode is activated, so that the drive motor drives the vehicle. This effectively balances the energy consumption of oil and electricity and reduces the overall energy consumption of the vehicle when the dual oil and electricity reduction mode is activated.

[0050] To illustrate the technical solution of this application, specific embodiments are described below. Figure 2 The vehicle control method provided in the embodiments of this application will be described in detail.

[0051] It should be understood that the embodiments of this application do not particularly limit the executing entity of the vehicle control method, as long as communication can be performed according to the vehicle control method of the embodiments of this application by running a program that records the code of the vehicle control method of the embodiments of this application. For example, the executing entity of the vehicle control method provided in the embodiments of this application can be a vehicle, or a vehicle controller in the vehicle, or a vehicle control device applied in the vehicle, such as a chip.

[0052] Figure 2 This is a flowchart illustrating a vehicle control method provided in an embodiment of this application. Figure 3 Including S201 to S204.

[0053] S201. When the vehicle's dual-mode (oil and electric) power reduction is activated, obtain the vehicle's mileage parameters and the power battery's charge parameters.

[0054] It should be understood that when the dual-mode power-saving system is activated, the vehicle can maintain its power performance while optimizing the switching between fuel and electricity to reduce both fuel consumption and battery drain, thereby effectively reducing overall energy consumption and improving range. For example, when the vehicle is traveling long distances at high speeds or needs to operate for extended periods, activating the dual-mode power-saving system allows the vehicle to maintain power output while maximizing energy savings.

[0055] For example, the mileage parameter may include the current cumulative mileage and the latched mileage. The current cumulative mileage may represent the total distance traveled by the vehicle since startup. The latched mileage may be used to represent the cumulative mileage marked during vehicle operation and under specific latching conditions (e.g., when the dual-mode power reduction is activated); the latched mileage may serve as a reference value during vehicle operation; for example, the latched mileage may be used to subsequently calculate the mileage difference in order to determine whether the vehicle meets the activation conditions of the intermittent mode, as detailed in the following embodiments.

[0056] For example, the power parameters include: latched power and current actual power. Current actual power can represent the remaining power of the battery (current state of charge) during vehicle operation; current actual power can be represented by SOC. Latched power can represent the actual power level marked under specific latching conditions (e.g., when the dual-mode power reduction is activated); latched power can serve as a reference quantity during vehicle operation. For example, latched power can be used to subsequently calculate the power difference to determine whether the battery's power change meets the activation conditions of the intermittent mode, as detailed in the following embodiments.

[0057] For example, the current actual charge level of the power battery can be obtained through the vehicle's Battery Management System (BMS).

[0058] For example, the cumulative mileage of a vehicle can be determined by the electronic control unit (ECU) in the vehicle.

[0059] S202. Based on the vehicle's mileage parameters and the power battery's charge parameters, determine whether the preset activation conditions for the intermittent mode are met.

[0060] For example, intermittent mode can be used to control the start-stop state of the engine and the driving state of the power battery, optimize the fuel and electricity consumption of the vehicle under specific driving conditions, and thus improve the energy efficiency and range of the whole vehicle.

[0061] For example, when the preset activation conditions are met, the intermittent mode will be activated, at which point the engine will stop and the vehicle will be driven by the power battery; when the preset activation conditions are not met, the engine will remain running to provide the necessary power output.

[0062] For example, the preset activation conditions can be conditions pre-configured by the vehicle or conditions set manually, and this application embodiment does not impose specific limitations on this.

[0063] For a detailed description of S202, please refer to the following embodiments, which will not be repeated here.

[0064] S203. Activate the intermittent mode if the preset activation conditions are met.

[0065] For example, when the dual-mode of reducing fuel consumption is activated, the intermittent mode is activated when the preset activation conditions are met. At this time, the engine can be shut down and the vehicle is driven by the power battery. That is, the vehicle does not consume fuel at this time, but only consumes electricity to drive the vehicle.

[0066] It is understood that in the embodiments of this application, the activation and deactivation of the intermittent mode are dynamic. Whether to activate the intermittent mode and when to deactivate it can be continuously detected based on real-time mileage and battery status.

[0067] S204. When the intermittent mode is activated, the engine is stopped and the drive motor in the vehicle is powered by the power battery so that the drive motor can drive the vehicle.

[0068] For example, when the intermittent mode is activated, the engine is stopped, and the power battery can serve as a power source for the vehicle, supplying power to the drive motor in the vehicle so that the drive motor can drive the vehicle.

[0069] For example, the vehicle continues to travel at a speed of 100 km / h, but the engine is off and the battery provides the necessary power.

[0070] Understandably, in the dual-mode of reducing both fuel and electricity consumption, by acquiring the vehicle's mileage parameters and the power battery's charge parameters, and dynamically activating the intermittent mode according to preset conditions, intelligent switching between fuel and electricity can be achieved, thereby optimizing the control method for reducing both fuel and electricity consumption.

[0071] In the embodiments of this application, when the vehicle's dual-mode power-fuel switching is activated, the vehicle's mileage parameters and the power battery's charge parameters are obtained; based on the vehicle's mileage parameters and the power battery's charge parameters, it is determined whether the preset activation conditions for the intermittent mode are met; if the preset activation conditions are met, the intermittent mode is activated; when the intermittent mode is activated, the engine is shut down, and the power battery supplies power to the drive motor in the vehicle, so that the drive motor drives the vehicle. Compared with the traditional dual-mode power-fuel switching that relies on a fixed threshold to control the switching between oil and electricity, this solution can shut down the engine and supply power to the drive motor in the vehicle through the power battery when the intermittent mode is activated, so that the drive motor drives the vehicle; and the solution determines whether the preset activation conditions for the intermittent mode are met based on the mileage parameters and the power battery's charge parameters, without relying on a fixed threshold to control the switching between oil and electricity; based on this, this solution can effectively balance the energy consumption of oil and electricity and reduce the overall vehicle energy consumption when the dual-mode power-fuel switching is activated, while the intermittent mode is activated.

[0072] In one possible embodiment of this application, the above-mentioned S201 includes: if a preset latching condition is met, then the actual charge of the power battery when the preset latching condition is met is taken as the latched charge, and the cumulative mileage of the vehicle when the preset latching condition is met is taken as the latched mileage; during the vehicle's operation, the current actual charge of the power battery and the current cumulative mileage of the vehicle are obtained.

[0073] For example, the preset latching conditions can be conditions pre-configured by the vehicle or conditions set manually, and this application embodiment does not impose specific limitations on this.

[0074] For example, during vehicle operation, the current actual battery charge and current cumulative mileage of the power battery can be periodically collected. When preset latching conditions are met, the actual battery charge when the preset latching conditions are met is used as the latched charge, and the cumulative mileage of the vehicle when the preset latching conditions are met is used as the latched mileage. Then, the current actual battery charge and current cumulative mileage of the power battery are periodically collected again until the preset latching conditions are met again. Then, the actual battery charge when the preset latching conditions are met is used as the latched charge, and the cumulative mileage of the vehicle when the preset latching conditions are met is used as the latched mileage.

[0075] For example, the preset latching conditions may include multiple preset latching conditions; each time any preset latching condition is detected to be met, the latched battery level and latched mileage can be updated. That is to say, the execution action 1, which uses the actual battery level when the preset latching conditions are met as the latched battery level, may not be the first execution; the vehicle may already have a latched battery level stored before, and the value of the latched battery level can be updated after executing action 1. Similarly, the execution action 2, which uses the vehicle's cumulative mileage when the preset latching conditions are met as the latched mileage, may not be the first execution; the vehicle may already have a latched mileage stored before, and the value of the latched mileage can be updated after executing action 2.

[0076] Understandably, given a fixed amount of latched power and a fixed mileage, the vehicle can determine the activation conditions for the intermittent mode based on these fixed amounts of latched power and mileage.

[0077] For example, in the dual-reduction mode (fuel and electricity), the vehicle can determine whether the activation conditions for intermittent mode are met based on the difference between the current accumulated mileage and the latched mileage (mileage difference) and the difference between the current actual battery charge and the latched battery charge (battery charge difference). If the activation conditions for intermittent mode are met, the vehicle will shut down the engine and power the drive motor through the battery to drive the vehicle, thereby achieving a dual reduction in fuel and electricity consumption. By acquiring battery and mileage parameters in real time using the above method, and combining them with preset latching and activation conditions, the vehicle can dynamically adjust the activation strategy of intermittent mode to optimize overall vehicle energy consumption.

[0078] For a detailed description of the preset latching conditions, please refer to the following embodiments, which will not be repeated here.

[0079] In the embodiments of this application, by detecting whether the current driving condition of the vehicle meets the preset latching conditions, and using the actual battery level when the preset latching conditions are met as the latched battery level and the cumulative driving mileage as the latched mileage, a benchmark value is provided for whether to activate the intermittent mode in the future, thereby improving the reliability of activating the intermittent mode.

[0080] In one possible embodiment of this application, the preset latching condition is any one of the following conditions:

[0081] Scenario 1: The dual-mode of reducing oil and electricity power has been activated instead of being previously activated.

[0082] For example, when a vehicle switches from a non-electric dual-mode (e.g., pure electric mode, economy mode) to an electric dual-mode, if the electric dual-mode is detected to have changed from being inactive to being active, the current actual charge of the power battery and the current cumulative mileage of the vehicle can be recorded and determined as the latched charge, and the current cumulative mileage can be determined as the latched mileage.

[0083] For example, when the dual-mode reduction of oil and electricity is changed from never being activated to being inactive, the above-mentioned actions of determining the latched power and latched mileage may be triggered for the first time at this time.

[0084] Understandably, when the dual-mode power reduction system changes from unactivated to activated, it indicates that the vehicle has just entered the dual-mode power reduction system. In order to measure whether entering the dual-mode power reduction system can effectively reduce the rate of fuel consumption and the power battery's charge consumption, it is necessary to trigger the locking of the current actual charge and the current cumulative mileage to obtain the locked charge and locked mileage, so as to determine whether the preset activation conditions of the intermittent mode are met. For example, to determine whether the preset activation conditions are met, it is necessary to comprehensively determine the charge difference obtained by subtracting the locked charge from the current actual charge and the mileage difference obtained by subtracting the locked mileage from the current cumulative mileage.

[0085] For example, when the vehicle is driving in hybrid mode and the hybrid power mode is not activated, the current actual battery charge and current cumulative mileage can be collected in real time. If the current actual battery charge (SOC) is 70% and the vehicle's cumulative mileage is 500 km, and the hybrid power mode is detected to be activated, the preset latching conditions are met. The battery charge at the time of activation (70%) and the vehicle's cumulative mileage at the time of activation (500 km) are used as the latched charge and mileage, respectively. As the vehicle continues to travel, the vehicle's BMS can continue to monitor the current actual battery charge. For example, after the vehicle has traveled 100 km, the battery charge may drop to 65%, and this 65% becomes the current actual charge. The vehicle's ECU continuously calculates the cumulative mileage; after traveling 100 km, the cumulative mileage may increase to 600 km.

[0086] Scenario 2: The dual-mode of reducing oil and electricity is activated and the intermittent mode changes from activated to inactive.

[0087] For example, if the dual-mode power reduction is activated and the intermittent mode changes from activated to inactive, the vehicle may already have previously determined latched battery level and latched mileage stored in it. In this case, the stored latched battery level and latched mileage can be updated to obtain the updated latched battery level and latched mileage.

[0088] Understandably, when both the hybrid and intermittent modes are activated, the engine shuts down, and the vehicle's battery discharges to power the drive motor, which then drives the vehicle. This causes the actual battery level to drop rapidly. When the intermittent mode changes from active to inactive, it indicates that the intermittent mode is now inactive. At this point, the engine can start, and the vehicle may charge the battery, thus fulfilling the intermittent mode activation conditions again. Therefore, to facilitate further assessment of whether the preset activation conditions for intermittent mode are met after the current moment, the current battery level and accumulated mileage can be re-locked.

[0089] For example, when the dual-mode power descent control is activated and the intermittent mode switches from active to inactive (e.g., when the State of Charge (SOC) drops to the threshold at which the intermittent mode was exited), the current actual battery charge and current cumulative mileage can be collected in real time. If the current actual battery charge is 58% and the vehicle's cumulative mileage is 750km, and the intermittent mode is detected changing from active to inactive (if the intermittent mode is active, then the dual-mode power descent control is active), the stored charge (e.g., previously stored charge could be 70%) can be updated to the current actual charge (58%), and the stored mileage (e.g., previously stored mileage was 600km) can be updated to the cumulative mileage (750km).

[0090] Case 3. When the intermittent mode is activated, the difference between the current actual power and the latched power is greater than the third preset power threshold.

[0091] For example, the third preset battery threshold can be a value pre-configured by the vehicle or a value set manually. This application embodiment does not impose specific restrictions on this.

[0092] For example, the third preset battery threshold can be a positive value; for example, the third preset battery threshold is 2%.

[0093] Understandably, if the difference between the current actual power and the latched power is greater than the third preset power threshold, it can be assumed that even when the intermittent mode is activated, the current actual power of the power battery is still increasing. In this case, it can be assumed that the vehicle is currently in a plug-in charging state (for example, the vehicle is currently being charged by an external charging station), or the vehicle is currently on a long downhill section and is charging the power battery through the energy recovery function.

[0094] It is also understandable that when the intermittent mode is activated, if the actual current charge of the power battery is still rising, the judgment period for judging the locked charge and locked mileage can be reset by updating the locked charge and locked mileage. This avoids interference from non-driving factors in judging when the intermittent mode exits, thereby improving the reliability of determining when the intermittent mode exits.

[0095] For example, when the dual-mode power reduction and intermittent mode are activated, the current actual power level of the power battery collected each time can be compared with the stored power level. If the difference between the current actual power level and the stored power level is greater than the third preset power level threshold (e.g., 2%), the stored power level (e.g., the previous stored power level could be 60%) can be updated to the current actual power level (63%). In addition, the stored mileage (e.g., the previous stored mileage was 600km) can be updated to the cumulative driving mileage (620km).

[0096] Case 4. When the intermittent mode is not activated, the difference between the current actual power and the latched power is less than the fourth preset power threshold.

[0097] For example, the fourth preset battery threshold can be a value pre-configured by the vehicle or a value set manually. This application embodiment does not impose specific restrictions on this.

[0098] For example, the fourth preset battery threshold can be a negative value; for instance, the fourth preset battery threshold is -3.5%.

[0099] Understandably, if the difference between the current actual charge and the latched charge is less than the second preset charge threshold, it indicates that the current actual charge of the power battery is decreasing rapidly and is in a low-speed priority power consumption state. In this case, there is no need to activate the intermittent mode to prioritize the use of the power battery to provide power output to the vehicle.

[0100] It is also understandable that when the intermittent mode is not activated, if the current actual charge of the power battery is detected to be decreasing at an accelerated rate (by subtracting the latched charge from the current actual charge and comparing the charge difference with the fourth preset charge threshold), the judgment period for the latched charge and latched mileage can be reset by updating the latched charge and latched mileage. This avoids interfering with the judgment on whether the intermittent mode needs to be activated, thereby improving the reliability of determining when the intermittent mode should be activated.

[0101] For example, when the intermittent mode is not activated, the current actual charge of the power battery collected each time can be compared with the stored charge. If the difference between the current actual charge and the stored charge is less than the fourth preset charge threshold (e.g., -3.5%), the stored charge (e.g., the previous stored charge could be 60%) can be updated to the current actual charge (56%). The stored mileage (e.g., the previous stored mileage was 600km) can be updated to the cumulative driving mileage (650km).

[0102] In the embodiments of this application, by latching the current actual charge of the power battery and the cumulative mileage of the vehicle under various preset latching conditions, the latched charge and latched mileage of the latching mechanism can be calibrated in a timely manner, thereby improving the accuracy of the activation and exit timing of the trigger detection intermittent mode.

[0103] In one possible embodiment of this application, S202 includes: subtracting the latched power from the current actual power to obtain a power difference; subtracting the latched mileage from the current cumulative mileage to obtain a mileage difference; and determining whether the preset activation conditions of the intermittent mode are met based on the power difference and the mileage difference.

[0104] For example, the actual change in the battery charge within a preset cumulative driving mileage can be determined by using the difference in charge and the difference in mileage.

[0105] As an example, if the actual charge of the power battery changes rapidly, it means that there is no need to activate the intermittent mode. In this case, the conventional oil-electric dual-reduction mode can still be used to achieve a balance in the oil-electric switching.

[0106] As another example, if the actual charge of the power battery changes slowly, it indicates that the intermittent mode needs to be activated to allow the power battery to discharge first, thereby ensuring the balance of switching between oil and electric power under the dual oil-electric power reduction mode.

[0107] In the embodiments of this application, the timing of vehicle activation of intermittent mode can be accurately detected by the difference in battery power and the difference in mileage, thereby achieving the optimal dynamic balance of fuel and electricity consumption in the dual-mode of reduced fuel and electricity consumption and improving the vehicle's driving range.

[0108] In one possible embodiment of this application, determining whether the preset activation conditions for the intermittent mode are met based on the difference in battery power and the difference in mileage includes the following two methods:

[0109] Method 1. If the mileage difference is less than or equal to the preset mileage threshold and the battery difference is greater than or equal to the first preset battery threshold, then the preset activation conditions of the intermittent mode are met.

[0110] The first preset power threshold is a positive value.

[0111] For example, the first preset battery threshold can be a value pre-configured by the vehicle or a manually calibrated value; this application embodiment does not impose specific limitations on this. For instance, the first preset battery threshold can be 1%.

[0112] For example, the first preset battery threshold can be a threshold determined by the current ambient temperature and engine coolant temperature. For instance, the first preset battery threshold can be positively correlated with both the current ambient temperature and engine coolant temperature; specifically, if the current ambient temperature is higher and the engine coolant temperature is higher, the first preset battery threshold is higher; if the current ambient temperature is lower and the engine coolant temperature is lower, the first preset battery threshold is lower.

[0113] For example, the preset mileage threshold can be a value pre-configured by the vehicle or a value manually calibrated; this application embodiment does not impose specific limitations on this. For example, the preset mileage threshold is 15km.

[0114] As one possible implementation, the preset mileage threshold can also be a value determined by the driving mode and the current actual battery level. In this case, the preset mileage threshold can also be referred to as forced intermittent mileage. For example, as shown in Table 1, Table 1 is a table illustrating the correspondence between the preset mileage threshold and the driving mode and the current actual battery level provided in an embodiment of this application. Table 1 is only an illustrative example of the correspondence between the preset mileage threshold and the driving mode and the current actual battery level; the specific correspondence can be determined by the actual scenario.

[0115] Table 1. Correspondence between preset mileage threshold, driving mode, and current actual battery level.

[0116]

[0117] For example, with a current battery level of 20%, if the driving mode is any one of Standard, Sport, 4WD, Snow, Mud, Sand, or Eco, the preset mileage threshold can be 18km; with a current battery level of 40%, if the driving mode is any one of Standard, Sport, 4WD, Snow, Mud, Sand, or Eco, the preset mileage threshold can be 15km; with a current battery level of 60%, if the driving mode is Standard, Sport, or 4WD... If the driving mode is any one of the following: Snow mode, Mud mode, Sand mode, or Economy mode, the preset mileage threshold can be 15km; if the current actual battery level is 80%, and the driving mode is any one of the following: Standard mode, Sport mode, 4WD mode, Snow mode, Mud mode, Sand mode, or Economy mode, the preset mileage threshold can be 12km; if the current actual battery level is 100%, and the driving mode is any one of the following: Standard mode, Sport mode, 4WD mode, Snow mode, Mud mode, Sand mode, or Economy mode, the preset mileage threshold can be 12km.

[0118] For example, when the mileage difference is less than or equal to a preset mileage threshold and the power difference is greater than or equal to a first preset power threshold, it can be determined that the current actual power of the power battery has risen abnormally (therefore, in the dual-power mode, the power battery power and fuel quantity should decrease). At this time, it can be determined that the preset activation conditions of the intermittent mode are met, thereby activating the intermittent mode and prioritizing the use of electricity to reduce fuel consumption.

[0119] For example, if the latched battery capacity is 60% and the latched mileage is 500km, after sequentially latching the battery capacity and mileage, the vehicle's cumulative mileage is 510km, and the current actual battery capacity is 63%. At this point, it is detected that if the mileage difference (10km) is less than or equal to the preset mileage threshold (15km), the battery capacity difference (3%) is greater than the first preset battery capacity threshold (1%). At this point, it is determined that the preset activation conditions of the intermittent mode are met, and the intermittent mode is activated to control the engine to stop, and the vehicle drives the vehicle through pure electric drive.

[0120] Method 2. If the mileage difference is greater than the preset mileage threshold and the battery difference is greater than or equal to the second preset battery threshold and less than zero, then the preset activation conditions of the intermittent mode are met.

[0121] The second preset power threshold is a negative value.

[0122] For example, the second preset battery threshold can be a value pre-configured by the vehicle or a manually calibrated value; this application embodiment does not impose specific limitations on this. For instance, the second preset battery threshold can be -3.5%.

[0123] As one possible implementation, the second preset battery threshold can be a value determined by the vehicle's driving mode. In this case, the second preset battery threshold can also be referred to as the forced intermittent SOC threshold. For example, as shown in Table 2, Table 2 is a correspondence table between a driving mode and a second preset battery threshold provided in an embodiment of this application. Table 2 is only an illustrative example of the correspondence between driving modes and the second preset battery threshold; the specific correspondence can be determined by the actual scenario.

[0124] Table 2. Correspondence between driving modes and the second preset battery threshold.

[0125] Driving Mode Second preset power threshold Standard mode -3.5％ Sports Mode -3.5％ Four-wheel drive mode -3.5％ Snow mode -3.4％ Mud mode -3.5％ Sandy mode -3.2％ economic model -3.5％ ... ...

[0126] For example, when the driving mode is Standard, Sport, 4WD, Mud, or Eco, the second preset battery threshold can be -3.5%; when the driving mode is Snow, the second preset battery threshold can be -3.4%; and when the driving mode is Sand, the second preset battery threshold can be -3.2%.

[0127] For example, when the mileage difference is greater than a preset mileage threshold and the power difference is greater than or equal to a second preset power threshold and less than zero, it can be determined that the current actual power of the power battery is decreasing at a lower rate than expected, and forced power consumption is required. At this time, it can be determined that the preset activation conditions of the intermittent mode are met, thereby activating the intermittent mode and prioritizing power consumption to reduce fuel consumption.

[0128] For example, if the latched battery level is 60% and the latched mileage is 500km; after sequentially latching the battery level and mileage, the vehicle's current cumulative mileage is 520km, and the current actual battery level is 58%; at this point, it is detected that if the mileage difference (20km) is less than or equal to the preset mileage threshold (15km), the battery level difference (-2%) is greater than the second preset battery level threshold (-3.5%). At this point, it is determined that the preset activation conditions for the intermittent mode are met, and the intermittent mode is activated to control the engine to stop. The vehicle then uses the battery to power the drive motor in the vehicle, so that the drive motor can drive the vehicle.

[0129] In the embodiments of this application, by detecting whether the power difference is greater than or equal to a first preset power threshold, and whether the power difference is greater than or equal to a second preset power threshold and less than zero, it is possible to detect whether the current actual power level is abnormally rising or falling, or other abnormal power level changes. In the case of abnormal power level changes, an intermittent mode is activated to prioritize the discharge of the power battery, so as to dynamically adjust the power battery level and reduce fuel consumption, thereby effectively balancing fuel and electricity consumption to reduce the overall vehicle energy consumption.

[0130] As one possible approach, when the intermittent mode is activated, the current actual power level is subtracted from the latched power level to obtain the power difference; based on the power difference, it is determined whether the preset exit conditions of the intermittent mode are met.

[0131] For example, the preset exit condition can be a condition pre-configured by the vehicle or a condition set manually. This application embodiment does not impose specific limitations on this.

[0132] For example, determining whether the preset exit condition of the intermittent mode is met based on the power difference may include: if the power difference is less than a fifth preset power threshold, then the preset exit condition of the intermittent mode is met.

[0133] For example, the fifth preset battery threshold can be a value pre-configured by the vehicle or a manually set value; this application embodiment does not impose specific limitations on this. For instance, the fifth preset battery threshold could be -3.5%.

[0134] For example, the fifth preset battery threshold can also be a value determined by the current ambient temperature, engine coolant temperature, and driving mode.

[0135] For example, when the intermittent mode is activated, if the latched power is 58% and the latched range is 520km, and the current actual power of the power battery is 54%, and the detected power difference (-4%) is less than the fifth preset power threshold (-3.5%), then it is determined that the preset exit condition of the intermittent mode is met, and thus the intermittent mode is exited.

[0136] Optionally, when the dual-mode power reduction is discontinued, the intermittent mode can be switched from active to inactive.

[0137] As one possible implementation, the method provided in this application embodiment further includes: when the power drive mode is detected to be the target hybrid mode, the current actual battery level is less than a sixth preset battery level threshold, the current vehicle speed is greater than a preset vehicle speed, and the current target battery level is greater than a preset target battery level threshold, the dual-mode of reducing both oil and electricity is activated.

[0138] For example, the target hybrid mode can be an intelligent hybrid mode, which can dynamically optimize the control strategy for the coordinated operation of the power source through intelligent algorithms.

[0139] For example, the target battery threshold can be a value pre-configured by the vehicle or a value set manually; this application embodiment does not impose specific limitations on this.

[0140] For example, the sixth preset battery threshold can be a value pre-configured by the vehicle or a value set manually. This application embodiment does not impose specific limitations on this.

[0141] As one possible implementation, the sixth preset battery threshold can be determined by the vehicle's driving mode. For example, as shown in Table 3, Table 3 is a correspondence table between a driving mode and a sixth preset battery threshold provided in an embodiment of this application. Table 3 is only an illustrative example of the correspondence between driving modes and the sixth preset battery threshold; the specific correspondence can be determined by the actual scenario.

[0142] Table 3. Correspondence between driving modes and the sixth preset battery threshold.

[0143] Driving Mode Sixth preset power threshold Standard mode 90％ Sports Mode 90％ Four-wheel drive mode 90％ Snow mode 90％ Mud mode 90％ Sandy mode 90％ economic model 80％ ... ...

[0144] For example, when the driving mode is Standard, Sport, 4WD, or Mud mode, the sixth preset battery threshold can be 90%. When the driving mode is Eco mode, the sixth preset battery threshold can be 80%.

[0145] For example, the preset vehicle speed can be a value pre-configured by the vehicle or a value set manually. This application embodiment does not impose specific limitations on this.

[0146] As one possible implementation, the preset vehicle speed can be a value determined by the driving mode and the current actual battery level. For example, as shown in Table 4, Table 4 is a table illustrating the correspondence between preset vehicle speed, driving mode, and current actual battery level provided in an embodiment of this application. Table 4 is only an illustrative example of the correspondence between preset vehicle speed, driving mode, and current actual battery level; the specific correspondence can be determined by the actual scenario. The unit of preset vehicle speed is km / h.

[0147] Table 4. Correspondence between current vehicle speed, driving mode, and current actual battery level.

[0148]

[0149] For example, when the driving mode is any one of Standard, Sport, 4WD, Snow, Mud, or Sand, and the current battery level is any one of 20%, 40%, 60%, 80%, or 100%, the preset speed is 70 km / h. When the driving mode is Eco, and the current battery level is any one of 20%, 40%, 60%, 80%, or 100%, the preset speed is 60 km / h.

[0150] As one possible implementation, the method provided in this application embodiment further includes: controlling the dual-mode power reduction to exit when the power drive mode is not the target hybrid mode, or the current actual battery level is greater than the seventh preset battery level threshold, or the current vehicle speed is the first preset value, or the current target battery level is the first preset value.

[0151] For example, the first preset value can be a value pre-configured by the vehicle or a value set manually; this application embodiment does not impose specific limitations on this. For instance, the first preset value can be 0.

[0152] For example, the seventh preset battery level threshold can be the sum of the sixth preset battery level threshold and the second preset value. The second preset value can be a value pre-configured by the vehicle or a manually set value; this embodiment does not impose specific limitations on this. For example, the second preset value could be 2%.

[0153] In one possible embodiment of this application, the method provided by the embodiments of this application further includes: when the intermittent mode is activated, increasing the engine starting power threshold from the current power threshold to a first target power threshold; and when the intermittent mode is not activated, decreasing the engine starting power threshold from the current power threshold to a second target power threshold.

[0154] For example, the first target power threshold and the second target power threshold can be values ​​pre-configured by the vehicle or values ​​set manually; this application embodiment does not impose specific limitations on this. The first target power threshold can be greater than the second target power threshold.

[0155] For example, when the engine triggers the starting power threshold, the engine can be started and power is generated by the engine fuel, which is transmitted to the wheels through mechanical components such as the crankshaft, gearbox, and drive shaft to drive the vehicle.

[0156] As an example, when the intermittent mode is activated, it can be determined that the power battery should be used to provide power output to the vehicle. At this time, by increasing the current power threshold, for example, by increasing the current power threshold to the first target power threshold, the engine is not easy to start, thereby enabling the power battery to be used to power the drive motor in the vehicle so that the drive motor can drive the vehicle.

[0157] As another example, when the intermittent mode is not activated, it can be determined that the engine fuel is used first to generate power to provide power output to the vehicle. At this time, the current power threshold can be reduced, for example, by reducing the current power threshold to the second target power threshold. The engine is easy to start, thereby achieving the goal of using the engine fuel to generate power to provide power output to the vehicle.

[0158] In the embodiments of this application, by dynamically adjusting the engine's starting power threshold, the ease of starting the engine can be controlled, thereby effectively balancing the energy consumption of both oil and electricity in the dual-mode of reducing oil and electricity consumption and lowering the overall vehicle energy consumption.

[0159] In one possible embodiment of this application, the method provided in this application further includes: when the dual-power mode is activated, obtaining the current actual power level and the current target power level of the power battery; determining the virtual target power level based on the current actual power level; and controlling the vehicle to operate in the dual-power mode based on the virtual target power level and the current target power level.

[0160] For example, a power battery has a target charge level that needs to be maintained, usually expressed as a percentage, such as 10% to 70%. The target charge level is used to keep the actual charge level of the power battery within a reasonable range, avoiding overcharging or over-discharging, thereby extending the battery's lifespan. The current target charge level, also known as the original target charge level, refers to the target charge level determined without considering the activation of the dual-mode throttling system. This original target charge level is affected by factors such as driving mode, ambient temperature, and vehicle speed. The virtual target charge level refers to an additional target charge level set considering the activation of the dual-mode throttling system.

[0161] For example, when the dual-mode power reduction is activated, either the virtual target power or the current target power can be selected as the target power used during the operation of the dual-mode power reduction, so that the power battery power is maintained at the target power selected from the virtual target power and the current target power during the operation of the dual-mode power reduction.

[0162] Regarding how to determine the virtual target power based on the current actual power level, and how to control the vehicle to operate in a dual-power mode based on the virtual target power level and the current target power level, please refer to the following embodiments, which will not be repeated here.

[0163] In the embodiments of this application, by determining a virtual target battery level, the target battery level of the vehicle can be further corrected when the dual-mode of reducing power consumption is activated. Then, the actual battery level can be adjusted based on the corrected target battery level to effectively balance the energy consumption of power consumption and reduce the overall energy consumption of the vehicle.

[0164] In one possible embodiment of this application, determining the virtual target power based on the current actual power consumption includes: detecting the current state of the intermittent mode; if the current state is active, subtracting the current actual power consumption from a first target value to obtain the virtual target power consumption; if the current state is inactive, adding the current actual power consumption to a second target value to obtain the virtual target power consumption.

[0165] The first and second target values ​​are determined by the current ambient temperature and engine coolant temperature.

[0166] As an example, if the intermittent mode is currently active, the engine is off, and the vehicle powers the drive motor via the battery to propel the vehicle. To minimize the current actual battery level, extend the pure electric range, and reduce the frequency of engine start-stop, the current actual battery level can be subtracted from a first target value to obtain a virtual target battery level. For example, if the first target value is 7%, and the current actual battery level is 60%, then the virtual target battery level could be 53%.

[0167] As another example, if the current state of intermittent mode is inactive, and the engine is running while the battery is charging or in hybrid mode, there is no need to forcibly reduce the current actual battery level to prioritize power conservation for subsequent power demands. Therefore, the current actual battery level can be added to a second target value to obtain a virtual target battery level. For example, if the second target value is 0%, and the current actual battery level is 60%, then the virtual target battery level can be 60%.

[0168] In the embodiments of this application, by combining the current state of the intermittent mode, and then calculating the virtual target power in both the active and inactive states, the target power of the power battery can be further precisely adjusted, thereby effectively taking into account the energy consumption of both gasoline and electric vehicles and reducing the overall vehicle energy consumption.

[0169] In one possible embodiment of this application, controlling the vehicle to operate in a dual-power mode based on a virtual target power level and a current target power level includes: comparing the virtual target power level and the current target power level; if the virtual target power level is greater than the current target power level, controlling the vehicle to operate in a dual-power mode with the virtual target power level; if the virtual target power level is less than or equal to the current target power level, controlling the vehicle to operate in a dual-power mode with the current target power level.

[0170] For example, when the virtual target battery level and the current target battery level are inconsistent, the difference between the two can be compared to determine whether to use the virtual or current target battery level to control the vehicle's operation in a dual-mode (fuel-electric reduction) to adapt to various operating conditions. For instance, in low-temperature environments, the virtual target battery level might be lowered due to the low engine coolant temperature, while the current target battery level might be higher. In this case, a more reasonable control target needs to be selected based on the comparison results.

[0171] As an example, if the virtual target battery level is greater than the current target battery level, the vehicle will be controlled to operate in a dual-charge mode with the virtual target battery level. For instance, if the virtual target battery level is 53% and the current target battery level is 50%, the dual-charge mode will be operated with the virtual target battery level. Specifically, the target battery level used during the operation of the dual-charge mode will be set to the virtual target battery level of 53%, so that the battery level will be maintained around the aforementioned virtual target battery level of 53% during the operation of the dual-charge mode.

[0172] As another example, if the virtual target battery level is less than the current target battery level, the vehicle will be controlled to operate in a dual-charge mode with the current target battery level. For instance, if the virtual target battery level is 53% and the current target battery level is 56%, the current target battery level will be used to operate in the dual-charge mode. Specifically, the target battery level used during the operation of the dual-charge mode will be set to 56% of the current target battery level, so that the battery level remains around 56% during the operation of the dual-charge mode.

[0173] For example, in low-temperature environments, if the current target battery level increases to 85% due to environmental adjustments, but the virtual target battery level decreases to 58% due to engine coolant temperature reduction, the vehicle will be controlled to operate in a dual-power reduction mode, with the current target battery level serving as the baseline.

[0174] To illustrate further, under high-temperature and high-speed conditions, if the current target battery level drops to 20% due to vehicle speed adjustment, but the virtual target battery level is adjusted to 27% due to the risk of battery overheating, the vehicle will be controlled to operate in a dual-power reduction mode based on the virtual target battery level.

[0175] In the embodiments of this application, by comparing the virtual target battery level and the current target battery level, it is determined whether to control the vehicle to operate in the dual-mode of reducing both oil and electricity based on the virtual target battery level or the current target battery level. This further enables the effective consideration of both oil and electricity energy consumption and reduces the overall vehicle energy consumption when the dual-mode of reducing both oil and electricity is activated.

[0176] It should be understood that the above examples are provided to help those skilled in the art understand the embodiments of this application, and are not intended to limit the embodiments of this application to the specific values ​​or scenarios exemplified. Those skilled in the art can obviously make various equivalent modifications or variations based on the above examples, and such modifications or variations also fall within the scope of the embodiments of this application.

[0177] The above text combined Figures 1 to 2 The vehicle control method provided in the embodiments of this application is described in detail below; the following will be combined with Figure 3 and Figure 4 The apparatus embodiments of this application are described in detail below. It should be understood that the apparatus in the embodiments of this application can perform the various methods described in the foregoing embodiments of this application, that is, the specific working processes of the various products described below can be referred to the corresponding processes in the foregoing method embodiments.

[0178] The following is combined with Figure 3 The vehicle control device provided in the embodiments of this application will be described in detail.

[0179] like Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a vehicle control device provided in an embodiment of this application.

[0180] For example, such as Figure 3 As shown, the control device includes:

[0181] The acquisition module 310 is used to acquire the vehicle's mileage parameters and the power battery's charge parameters when the vehicle's dual-mode power reduction is activated.

[0182] The determination module 320 is used to determine whether the preset activation conditions of the intermittent mode are met based on the vehicle's mileage parameters and the power battery's charge parameters.

[0183] Activation module 330 is used to activate the intermittent mode when preset activation conditions are met;

[0184] The control module 340 is used to control the engine to stop when the intermittent mode is activated, and to power the drive motor in the vehicle through the power battery so that the drive motor can drive the vehicle.

[0185] As one possible implementation, the acquisition module 310 is specifically used to: if the preset latching conditions are met, use the actual charge of the power battery when the preset latching conditions are met as the latched charge, and use the cumulative mileage of the vehicle when the preset latching conditions are met as the latched mileage; during the vehicle's operation, acquire the current actual charge of the power battery and the current cumulative mileage of the vehicle.

[0186] As one possible implementation, module 320 is specifically used to subtract the latched power from the current actual power to obtain the power difference; subtract the latched mileage from the current cumulative mileage to obtain the mileage difference; and determine whether the preset activation conditions of the intermittent mode are met based on the power difference and the mileage difference.

[0187] As one possible implementation, the determining module 320 is specifically used to determine that the preset activation condition of the intermittent mode is met if the mileage difference is less than or equal to a preset mileage threshold and the power difference is greater than or equal to a first preset power threshold; if the mileage difference is greater than a preset mileage threshold and the power difference is greater than or equal to a second preset power threshold and less than zero, then the preset activation condition of the intermittent mode is met, where the first preset power threshold is a positive value and the second preset power threshold is a negative value.

[0188] As one possible implementation, the acquisition module 310 is also used to acquire the current actual charge and the current target charge of the power battery when the dual-power mode is activated; the determination module 320 is also used to determine the virtual target charge based on the current actual charge; and the control module 340 is also used to control the vehicle to operate in the dual-power mode based on the virtual target charge and the current target charge.

[0189] As one possible implementation, the determining module 320 is specifically used to detect the current state of the intermittent mode; if the current state is an active state, the current actual power is subtracted from the first target value to obtain the virtual target power; if the current state is an inactive state, the current actual power is added to the second target value to obtain the virtual target power; wherein, the first target value and the second target value are determined by the current ambient temperature and the engine coolant temperature.

[0190] As one possible implementation, the control module 340 is specifically used to: compare the virtual target battery level with the current target battery level; if the virtual target battery level is greater than the current target battery level, control the vehicle to operate in a dual-power mode with reduced power consumption at the virtual target battery level; if the virtual target battery level is less than or equal to the current target battery level, control the vehicle to operate in a dual-power mode with reduced power consumption at the current target battery level.

[0191] As one possible implementation, the determining module 320 is also configured to, when the intermittent mode is activated, increase the engine starting power threshold from the current power threshold to a first target power threshold; and when the intermittent mode is not activated, decrease the engine starting power threshold from the current power threshold to a second target power threshold.

[0192] It should be noted that the vehicle control device provided in the above embodiments is only illustrated by the division of the above functional modules when executing the vehicle control method. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above.

[0193] Furthermore, the vehicle control device and vehicle control method embodiments provided in the above embodiments belong to the same concept.
