Description

Technical Field

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

[0002] With the rapid development of the automotive industry and the continuous progress of society, while striving for higher vehicle performance, higher demands are being placed on the driving experience and driving range. Currently, after a vehicle starts, its thermal management system often operates at maximum power. However, when the thermal management system operates at high power, it increases the vehicle's energy consumption, thereby reducing its driving range. Summary of the Invention

[0003] This application provides a vehicle control method and related apparatus that can improve the driving range of a vehicle.

[0004] In a first aspect, embodiments of this application provide a vehicle control method, which can be executed by a vehicle control device. The vehicle control device may be a device with control capabilities and / or computing capabilities, or a software and / or hardware module within a separate device.

[0005] The vehicle control method includes: a vehicle control device acquiring vehicle driving parameters and / or vehicle driving modes, the driving parameters including mileage and / or driving duration. The vehicle driving mode belongs to at least two driving modes, including a first driving mode and a second driving mode, wherein the energy consumption level of the first driving mode is lower than that of the second driving mode; when the value of the vehicle driving parameters is less than a first threshold, or when the vehicle driving mode is the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be lower than a second threshold.

[0006] The vehicle's mileage can be determined based on the vehicle's wheel speed sensors and wheel parameters, or based on the vehicle's navigation information. Wheel parameters may include the wheel's diameter or radius. The vehicle's driving time can be determined based on the vehicle's timer, or based on the vehicle's navigation information. The thermal management system may include at least one of the following: an air conditioner, a battery temperature control system, a seat heating device, or a contact heating device.

[0007] At least two driving modes must be available, and the energy consumption levels of any two driving modes must be different. For example, the at least two driving modes may include: Ecology Conservation Optimization (ECO) mode, Normal mode, and Sport mode. The Ecology Conservation Optimization mode has a lower energy consumption level than the Normal mode, and the Normal mode has a lower energy consumption level than the Sport mode. The vehicle's driving mode can be user-set or the default. The vehicle's driving mode can also be recommended to the user based on their driving habits.

[0008] The first threshold can be a pre-set threshold. If the vehicle's driving parameters are lower than the first threshold, it indicates that the vehicle has traveled a short distance or for a short duration, suggesting that the trip was short-distance.

[0009] The second threshold can be a pre-set threshold. The thermal management system can operate at different power levels. If the power of the thermal management system is less than the second threshold, it indicates that the thermal management system is operating at a lower power level, which can reduce the vehicle's power consumption.

[0010] In this embodiment, when the vehicle's driving parameters are low or the energy consumption level of the vehicle's driving mode is low, the thermal management system is controlled to operate at a lower power, thereby controlling the power of the thermal management system and preventing it from continuously operating at maximum power. This reduces the vehicle's power consumption, thereby increasing the vehicle's range and reducing unnecessary energy waste caused by short-distance travel.

[0011] In one possible implementation of the first aspect, when the driving parameters are less than a first threshold, or when the vehicle's driving mode is the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be lower than a second threshold. This can be achieved, but is not limited to, the following methods:

[0012] If the driving parameters are less than a first threshold, the vehicle control unit controls the power of the vehicle's thermal management system to be lower than a second threshold; or...

[0013] When the vehicle is in the first driving mode, the vehicle control unit controls the power of the vehicle's thermal management system to be lower than the second threshold; or,

[0014] When the driving parameter values ​​are less than the first threshold and the vehicle is in the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be lower than the second threshold.

[0015] In this embodiment, the power of the vehicle's thermal management system is controlled to be lower than a second threshold when any of the following conditions are met: Condition 1: The value of the driving parameter is less than a first threshold; Condition 2: The vehicle's driving mode is a first driving mode; Condition 3: The value of the driving parameter is less than the first threshold and the vehicle's driving mode is the first driving mode. Based on at least one of the vehicle's driving parameter values ​​and driving mode, the vehicle's thermal management system can be controlled to operate at a lower power, thereby reducing the vehicle's power consumption and increasing its driving range.

[0016] Optionally, when the values ​​of the driving parameters are less than the first threshold, the vehicle control device controls the power of the vehicle's thermal management system to be lower than the second threshold. This can be achieved, but is not limited to, the following methods:

[0017] When the driving parameter values ​​are less than the first threshold and the vehicle is in the second driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be lower than the second threshold.

[0018] In this embodiment, the vehicle's driving parameters are less than a first threshold, indicating that the vehicle's mileage or driving time is short, and the trip is short-distance. The vehicle's driving mode is the second driving mode, indicating that the energy consumption level of the driving mode is high. When the driving parameters are low and the energy consumption level of the driving mode is high, controlling the thermal management system to operate at lower power can reduce the vehicle's power consumption and increase its driving range.

[0019] Optionally, when the values ​​of the driving parameters are less than the first threshold, the vehicle control device controls the power of the vehicle's thermal management system to be lower than the second threshold. This can be achieved, but is not limited to, the following methods:

[0020] When the driving parameter values ​​are less than the first threshold and the vehicle is in the second driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold.

[0021] In this embodiment, when the driving parameters are small and the energy consumption level of the vehicle's driving mode is high, the thermal management system is controlled to operate at a higher power so that the power of the thermal management system is adapted to the energy consumption level of the vehicle's driving mode.

[0022] In one possible implementation of the first aspect, the vehicle control method further includes:

[0023] When the values ​​of driving parameters are greater than or equal to the first threshold, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold.

[0024] In this embodiment, if the vehicle's driving parameters are greater than or equal to a first threshold, it indicates that the vehicle's mileage and driving time are relatively long, suggesting a long-distance trip. When the driving parameters are high, the thermal management system is controlled to operate at higher power, thereby improving the user's long-distance travel experience.

[0025] In one possible implementation of the first aspect, when the value of the driving parameter is greater than or equal to a first threshold, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to a second threshold. This can be achieved, but is not limited to, the following methods:

[0026] When the value of the driving parameter is greater than or equal to the first threshold and the vehicle is in the second driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold.

[0027] In this embodiment, if the vehicle's driving parameters are greater than or equal to a first threshold, it indicates that the vehicle's mileage and driving time are relatively long, suggesting a long-distance trip. The vehicle is in a second driving mode, indicating a higher energy consumption level. When both the driving parameters and the driving mode have high energy consumption, controlling the thermal management system to operate at higher power not only improves the user's long-distance travel experience but also ensures that the thermal management system's power output matches the energy consumption level of the driving mode.

[0028] Optionally, when the values ​​of the driving parameters are greater than or equal to the first threshold, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold. This can be achieved, but is not limited to, the following methods:

[0029] When the value of the driving parameter is greater than or equal to the first threshold and the vehicle is in the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold.

[0030] In this embodiment of the application, when the driving parameters are large and the energy consumption level of the vehicle's driving mode is low, controlling the thermal management system to operate at a higher power can improve the user's long-distance travel experience.

[0031] Optionally, the above vehicle control method also includes:

[0032] When the value of the driving parameter is greater than or equal to the first threshold and the vehicle is in the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be less than the second threshold.

[0033] In this embodiment, when the driving parameters are large and the energy consumption level of the vehicle's driving mode is low, the thermal management system is controlled to operate at a lower power, so that the power of the thermal management system is adapted to the energy consumption level of the vehicle's driving mode.

[0034] In one possible implementation of the first aspect, the vehicle control method further includes:

[0035] When the vehicle is in the second driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be greater than or equal to the second threshold.

[0036] In this embodiment, the vehicle's driving mode is the second driving mode, indicating that the energy consumption level of the vehicle's driving mode is relatively high. When the energy consumption level of the vehicle's driving mode is high, the thermal management system is controlled to operate at a higher power, so that the power of the thermal management system is adapted to the energy consumption level of the vehicle's driving mode.

[0037] In one possible implementation of the first aspect, the thermal management system operates in a first mode or a second mode, where the power corresponding to the first mode is less than the power corresponding to the second mode.

[0038] In this embodiment, the power corresponding to the first mode can be either the average power or the maximum power of the first mode. The power corresponding to the second mode can be either the average power or the maximum power of the second mode. The power corresponding to the first mode being less than the power corresponding to the second mode can be either the maximum power of the first mode being less than the maximum power of the second mode, or the average power of the first mode being less than the average power of the second mode. The power ranges of the first mode and the second mode may or may not overlap; this embodiment does not impose any limitations on this.

[0039] When the thermal management system operates in the first mode, its power is a first power; when it operates in the second mode, its power is a second power. The first power is less than the second power. For example, when the thermal management system operates in the first mode, its power is below a second threshold; when it operates in the second mode, its power is greater than or equal to the second threshold.

[0040] In one possible implementation of the first aspect, when the vehicle's driving parameters include mileage, the vehicle's mileage belongs to a first mileage or a second mileage, the value of the first mileage is less than the value of the second mileage, the first mileage corresponds to a first mode, and the second mileage corresponds to a second mode.

[0041] When the vehicle's driving parameters include driving time, the vehicle's driving time belongs to either the first driving time or the second driving time. The value of the first driving time is less than the value of the second driving time. The first driving time corresponds to the first mode, and the second driving time corresponds to the second mode.

[0042] The first mileage value can be a specific mileage value or a mileage range. The second mileage value can also be a specific mileage value or a mileage range. If both the first and second mileage values ​​are mileage ranges, the first mileage value being less than the second mileage value can be either the maximum value of the mileage range corresponding to the first mileage value being less than the maximum value of the mileage range corresponding to the second mileage value, or the median value of the mileage range corresponding to the first mileage value being less than the median value of the mileage range corresponding to the second mileage value.

[0043] The first driving time can be a specific duration or a time interval. The second driving time can also be a specific duration or a time interval. If both the first and second driving times are time intervals, the first driving time being less than the second driving time can be due to either the maximum value of the first driving time interval being less than the maximum value of the second driving time interval, or the median value of the first driving time interval being less than the median value of the second driving time interval.

[0044] In this embodiment, there is a first correspondence between the vehicle's driving parameters and the operating mode of the thermal management system. The vehicle control device can determine the operating mode of the thermal management system based on the vehicle's driving parameters and this first correspondence.

[0045] For example, when the vehicle's driving parameters include mileage, the first correspondence is used to indicate the correspondence between at least two mileage ranges and at least two driving modes. The at least two mileage ranges include either the first mileage or the second mileage, and the at least two driving modes include the first mode and the second mode, with the first mileage corresponding to the first mode and the second mileage corresponding to the second mode. If the vehicle's mileage is the first mileage, the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is below a second threshold. If the vehicle's mileage is the second mileage, the vehicle control device determines that the thermal management system is operating in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0046] For example, when the vehicle's driving parameters include driving duration, the first correspondence is used to indicate the correspondence between at least two driving durations and at least two modes. The at least two driving durations include either the first driving duration or the second driving duration mentioned above, and the at least two modes include the first mode mentioned above and the second mode mentioned above. The first driving duration corresponds to the first mode, and the second driving duration corresponds to the second mode. If the vehicle's driving duration is the first driving duration, the vehicle control device determines that the thermal management system operates in the first mode, and the power of the thermal management system is below a second threshold. If the vehicle's driving duration is the second driving duration, the vehicle control device determines that the thermal management system operates in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0047] In one possible implementation of the first aspect, when the vehicle's driving parameters include mileage and driving time, the vehicle's mileage belongs to a first mileage or a second mileage, and the vehicle's driving time belongs to a first driving time or a second driving time.

[0048] When the vehicle's mileage is within the first mileage or the vehicle's driving time is within the first driving time, the vehicle's driving parameters correspond to the first mode.

[0049] When the vehicle's mileage and driving time both fall within the second mileage and second driving time range, the vehicle's driving parameters correspond to the second mode.

[0050] In this embodiment, there is a first correspondence between the vehicle's driving parameters and the operating mode of the thermal management system. The vehicle control device can determine the operating mode of the thermal management system based on the vehicle's driving parameters and this first correspondence.

[0051] For example, when the vehicle's driving parameters include mileage, a first correspondence is used to indicate the correspondence between at least two mileages and at least two driving modes, and to indicate the correspondence between at least two driving durations and at least two driving modes. The at least two mileages include either the first mileage or the second mileage; the at least two driving durations include either the first driving duration or the second driving duration; and the at least two driving modes include both the first mode and the second mode. The first mileage corresponds to the first mode, and the second mileage corresponds to the second mode. The first driving duration corresponds to the first mode, and the second driving duration corresponds to the second mode. If the vehicle's mileage is the first mileage and the vehicle's driving duration is the first driving duration, the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is below a second threshold. If the vehicle's mileage is the first mileage and the vehicle's driving duration is the second driving duration, the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is below the second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the first driving time range, the vehicle control unit determines that the thermal management system is operating in the first mode, and the power of the thermal management system is lower than the second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the second driving time range, the vehicle control unit determines that the thermal management system is operating in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0052] In this embodiment, the driving parameters of the vehicle correspond to the mode with the lowest power among the modes corresponding to driving mileage and driving time, which can reduce the power consumption of the vehicle and thus improve the driving range of the vehicle.

[0053] Optionally, if the vehicle's mileage falls within a first mileage range and the vehicle's driving time falls within a second driving time range, the vehicle control device determines that the thermal management system operates in a second mode, and the power of the thermal management system is greater than or equal to a second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the first driving time range, the vehicle control device determines that the thermal management system operates in a second mode, and the power of the thermal management system is greater than or equal to a second threshold.

[0054] In this embodiment, the driving parameters of the vehicle correspond to the mode with the highest power among the modes corresponding to driving mileage and driving time, which can improve the user's travel experience.

[0055] In another possible implementation of the first aspect, the first correspondence is pre-set.

[0056] In this embodiment, the first correspondence is preset, and the working mode of the thermal management system can be quickly determined based on the first correspondence and the vehicle's driving parameters.

[0057] In another possible implementation of the first aspect, when the vehicle's driving mode is a first driving mode, the thermal management system can operate in either the first or second mode. When the vehicle's driving mode is a second driving mode, the thermal management system can operate in either the first or second mode.

[0058] In this embodiment, under the same driving mode, the thermal management system can operate in at least two different power modes, thereby supporting the dynamic adjustment of the power of the thermal management system under the driving mode, thereby achieving higher energy management efficiency and reducing the power consumption of the vehicle.

[0059] In another possible implementation of the first aspect, the power of the vehicle's thermal management system is obtained based on the vehicle's driving parameters and / or driving mode, as well as an artificial intelligence (AI) model. For example, the vehicle control unit inputs the vehicle's driving parameters into the AI ​​model to obtain the power of the vehicle's thermal management system.

[0060] In this embodiment, the vehicle control device inputs the vehicle's driving parameters into the AI ​​model to obtain the power of the vehicle's thermal management system. The power of the vehicle's thermal management system can be quickly obtained based on the vehicle's driving parameters and the AI ​​model.

[0061] Optionally, the above driving parameters may also include road condition parameters. Road condition parameters may include at least one of the following: whether the road surface is icy, whether the road surface is wet, whether the road surface is bumpy, and whether there is traffic congestion.

[0062] In another possible implementation of the first aspect, the vehicle control method further includes: the vehicle control device determining the state of at least one of the following based on the vehicle's driving parameters: vehicle lights, windows, curtains, and sunroof.

[0063] The status of vehicle lights can include whether the vehicle lights are on and their power output. The status of vehicle windows can include whether the windows are open or closed. The status of the sunroof can include whether it is open or closed. The status of vehicle curtains can include whether they are open or closed.

[0064] When the vehicle's driving parameters are low, the status of the vehicle's lights, windows, curtains, and sunroof can be controlled to reduce the vehicle's power consumption.

[0065] In another possible implementation of the first aspect, the vehicle's mileage is determined based on the vehicle's wheel speed sensors, and the vehicle's travel time is determined based on the vehicle's timer.

[0066] In this embodiment, the mileage is determined based on the vehicle's wheel speed sensors. The mileage changes in real time during vehicle operation, improving the reliability of the mileage measurement compared to a predicted mileage, thus enhancing the accuracy of determining the target mode based on the mileage. The driving time is determined based on the vehicle's timer, also changing in real time during vehicle operation. Compared to a predicted driving time, this improves the reliability of the driving time measurement, further enhancing the accuracy of determining the target mode based on the driving time. The target mode can dynamically change with the mileage, thereby dynamically adjusting the power of the thermal management system to achieve higher energy management efficiency and reduce vehicle energy consumption.

[0067] In another possible implementation of the first aspect, the vehicle's mileage and / or driving time are determined based on the vehicle's navigation information.

[0068] In this embodiment, the vehicle's mileage and travel time can be determined using the vehicle's navigation information. The navigation information can estimate the current mileage and travel time, thereby accurately determining the vehicle's mileage and travel time, and consequently accurately determining the power of the thermal management system.

[0069] In another possible implementation of the first aspect, the vehicle's mileage includes: the mileage already traveled after the vehicle is started, or the mileage already traveled after the thermal management system is started; the driving time includes: the driving time already traveled after the vehicle is started, or the driving time already traveled after the thermal management system is started.

[0070] In this embodiment, the vehicle's mileage can be the mileage already traveled since the vehicle started, or the mileage already traveled since the thermal management system started. The vehicle's mileage is the distance traveled during the current trip, not the total mileage, which can reduce the power consumption during the current trip. The vehicle's driving time can be the driving time already traveled since the vehicle started, or the driving time already traveled since the thermal management system started. The vehicle's driving time is the duration of the current trip, not the total driving time, which can reduce the power consumption during the current trip.

[0071] In another possible implementation of the first aspect, the thermal management system includes at least one of the following: an air conditioner, a battery temperature control system, a seat heating device, and a contact heating device.

[0072] In this embodiment, the thermal management system can control the temperature set by the air conditioner, control the temperature of the battery through the battery temperature control system, control the temperature of the seat through the seat heating device, and control the temperature of the steering wheel, fireplace, etc. through the contact heating device, thereby controlling the temperature of the cooling or heating devices in the vehicle.

[0073] The battery's temperature control system includes a heating element and a cooling device. When the battery temperature is too low, the heating element can heat the battery; when the battery temperature is too high, the cooling device can cool the battery.

[0074] Seat heating devices can include heating the seats. When the temperature inside the vehicle is low, the seat heating device can raise the temperature of the seats, thereby improving the user's riding experience.

[0075] Contact heating devices may include any one or more combinations of the following: positive temperature coefficient (PTC) heaters, negative temperature coefficient (NTC) thermistors, liquid heaters, air heaters, and electric heaters.

[0076] In another possible implementation of the first aspect, at least one object includes a first object and a second object, and the thermal management system is used to control the power corresponding to the first object and the power corresponding to the second object; the priority of the first object is greater than the priority of the second object, and the power corresponding to the first object is greater than the power corresponding to the second object.

[0077] In this embodiment of the application, the thermal management system can control higher priority objects to have higher power, thereby ensuring that the temperature of higher priority objects is preferentially regulated, thereby improving the cooling or heating effect of higher priority objects.

[0078] Secondly, embodiments of this application provide a vehicle control device, which includes a unit for performing the method as described in any of the first aspects.

[0079] In one possible implementation, the device includes:

[0080] The communication unit is used to acquire the vehicle's driving parameters and / or driving mode, including driving mileage and / or driving time; the vehicle's driving mode includes a first driving mode or a second driving mode, wherein the energy consumption level of the first driving mode is lower than that of the second driving mode.

[0081] The processing unit is used to control the power of the vehicle's thermal management system to be lower than a second threshold when the value of the vehicle's driving parameters is less than a first threshold or when the vehicle's driving mode is a first driving mode.

[0082] Regarding the processing unit and communication unit of the second aspect and any possible implementation, the steps performed thereon can be referred to the corresponding implementation of the first aspect.

[0083] For the technical effects of the second aspect and any possible implementation, please refer to the description of the technical effects corresponding to the first aspect and the corresponding implementation.

After the information is output by the processor, it may require further processing before reaching the transceiver. Similarly, when the processor receives input information, the transceiver (or communication interface, or transmitting module) receives the information and inputs it to the processor. Furthermore, after the transceiver receives the information, it may require further processing before being input to the processor.

[0111] The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that, unless otherwise specified or logically conflicting, the terminology and / or descriptions between the various embodiments of this application are consistent and can be mutually referenced, and technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0112] It should be understood that in this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0113] It should be noted that, in this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0114] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various information, thereby reducing instruction overhead to some extent. The information to be instructed can be sent as a whole or divided into multiple sub-information units, and the sending period and / or timing of these sub-information units can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information units can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.

[0115] It should be noted that in this application, "send" can be understood as "output" and "receive" can be understood as "input". "Send information to A", where "to A" simply indicates the direction of information transmission, and A is the destination, does not limit "send information to A" to a direct transmission over the air interface. "Send information to A" includes sending information directly to A, as well as sending information indirectly to A through a transmitter. Therefore, "send information to A" can also be understood as "outputting information destined for A". Similarly, "receive information from A" indicates that the source of the information is A, including receiving information directly from A, as well as receiving information indirectly from A through a receiver. Therefore, "receive information from A" can also be understood as "inputting information from A".

[0116] The terminology used in the embodiments of this application will be explained below.

[0117] A thermal management system is a system used to manage the temperature of various components of a vehicle. Through integrated system design, the thermal management system optimizes the heat exchange process of various vehicle components and regulates the flow of heat energy in subsystems such as the powertrain, heat pump system, and battery pack.

[0118] An electronic control unit (ECU) can collect sensor data, process the collected sensor data, and output commands or data.

[0119] Improving the driving range of vehicles (such as electric vehicles, hybrid vehicles, and gasoline vehicles) is a key focus during vehicle development. When a vehicle has been stationary for a considerable period, the thermal management system needs time to adjust the interior temperature to a comfortable level. To enhance the passenger experience, the thermal management system often operates at maximum power after the vehicle is started. However, high-power operation increases energy consumption, thus reducing the driving range. For example, when a user travels short distances, if the interior and battery temperatures have just reached or not yet reached their target temperatures, energy is wasted, resulting in higher energy consumption for short trips.

[0120] In one possible implementation, heating or cooling power is dynamically adjusted based on the vehicle's real-time temperature to optimize energy consumption. While real-time adjustment of heating or cooling power can improve energy efficiency, the effect of real-time adjustment is limited during short trips due to rapid temperature changes in the vehicle and battery, and may still lead to energy waste.

[0121] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a vehicle system provided in an embodiment of this application. Figure 1 As shown, the vehicle system 100 includes: a vehicle control unit 10, an ECU 20, and a thermal management system 30. The number of ECUs 20 can be one or more. Figure 1 Taking ECU20 as an example, where there is one ECU20.

[0122] The vehicle control unit 10 is a device with control and / or computing capabilities. The vehicle control unit 10 can obtain the vehicle's driving parameters from the ECU 20 and control the power of the vehicle's thermal management system based on the vehicle's driving parameters and / or the vehicle's driving mode.

[0123] As an example of hardware implementation, the vehicle control device 10 may include at least one processor, which is a module with processing capabilities. In one implementation, the processor includes circuitry capable of reading and executing instructions, such as an arithmetic logic unit (ALU), processor core, central processing unit (CPU), microprocessor, microcontroller unit (MCU), graphics processing unit (GPU), image signal processor (ISP), or digital signal processor (DSP). In another implementation, the processor implements certain functions through the logical relationships of hardware circuitry, which may be fixed or reconfigurable. For example, the processor may be a hardware circuitry implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In reconfigurable hardware circuitry, the process of the processor loading a configuration document and configuring the hardware circuitry can be understood as the process of the processor loading instructions to implement the corresponding functions. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. In some implementations, the vehicle control device 10 includes at least one processor integrated as a system-on-chip (SOC), which is commonly referred to as an SOC by those skilled in the art. The SOC may include at least one processor, and when the SOC includes multiple processors, the types of processors can be different, such as including a CPU and an NPU.

[0124] As an example of software implementation, the vehicle control device 10 may include software functional units. As another example of a software functional unit, the vehicle control device 10 includes one or more of the following: an executable computer program, computer code, or computer instructions, where "executable" means capable of running on a processor or computing instance. As yet another example of a software functional unit, the vehicle control device 10 includes a computing instance, which may include a virtual machine or a container. A virtual machine is a computer system with complete hardware system functionality simulated by software, running in an isolated environment. A container is an isolated environment obtained by packaging applications and application dependencies.

[0125] For example, the vehicle control device 10 may include any of the following: a vehicle controller, a driving controller, or a domain controller.

[0126] ECU20 can collect sensor data, process the collected sensor data, and output commands or data. ECU20 can determine the vehicle's mileage based on the vehicle's wheel speed sensors and wheel parameters, and ECU20 can also determine the vehicle's driving time based on the vehicle's timer. ECU20 can send the vehicle's driving parameters (mileage and / or driving time) to the vehicle control unit 10.

[0127] The thermal management system 30 is a system used to manage the temperature of various components of a vehicle. Through integrated system design, the thermal management system 30 optimizes the heat exchange process of various vehicle components and regulates the heat flow of subsystems such as the powertrain, heat pump system, and battery pack. The thermal management system can control the temperature of various components through methods such as water cooling, liquid cooling, air cooling, and PTC heating. For example, the thermal management system 30 may include at least one of the following: an air conditioner, a battery temperature control system, a seat heating device, and a contact heating device. The thermal management system 30 can control the power of the air conditioner, the battery temperature control system, the seat heating device, and the contact heating device.

[0128] The above description of the vehicle system and the modules can be applied to the embodiments described below.

[0129] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a vehicle control method provided in an embodiment of this application. Figure 2 As shown, this vehicle control method is applied to the aforementioned vehicle system 100, for example, executed by the vehicle control device 10. The vehicle control method includes steps 201 to 202. The order of steps presented here is merely an example; the embodiments of this application are also applicable to other order of step execution, multiple executions of one or more steps, etc.

[0130] 201. The vehicle control unit acquires the vehicle's driving parameters and / or the vehicle's driving mode.

[0131] A vehicle control device is a device with control and / or computing capabilities. For example, a vehicle control device may be the vehicle control device 10 described above.

[0132] The driving parameters include mileage and / or driving time.

[0133] The driving time of a vehicle is the duration of a single trip. The driving time can be determined based on the vehicle's timer or navigation information.

[0134] A vehicle's mileage is the distance it travels in a single trip. The mileage can be determined based on wheel speed sensors and wheel parameters, or based on navigation information. Wheel parameters can include the wheel's diameter or radius. For example, S1 = 2π × d1 × n1 × T, where S1 is the vehicle's mileage, d1 is the wheel diameter (d1 can be in meters), n1 is the wheel's rotational speed (n1 can be in revolutions per second), and T is the vehicle's travel time.

[0135] In this embodiment, the vehicle's driving time is determined based on the vehicle's timer, and the vehicle's mileage is determined based on the vehicle's wheel speed sensors and wheel parameters. This ensures high real-time performance and reliability of the driving time and mileage. Even when the user's mileage and driving time cannot be predicted through navigation information, the power of the thermal management system can be effectively adjusted to reduce vehicle power consumption, increase the vehicle's range, and minimize unnecessary energy waste caused by short-distance travel.

[0136] The vehicle's driving mode belongs to at least two driving modes, including a first driving mode and a second driving mode, wherein the energy consumption level of the first driving mode is lower than that of the second driving mode.

[0137] At least two driving modes must be available, and the energy consumption levels of any two driving modes must be different. For example, the at least two driving modes may include: Eco mode, Standard mode, and Sport mode. Specifically, Eco mode has a lower energy consumption level than Standard mode, and Standard mode has a lower energy consumption level than Sport mode. The vehicle's driving mode can be user-set or the default. The vehicle's driving mode can also be recommended to the user based on their driving habits.

[0138] In one possible implementation, the vehicle's mileage includes: the mileage already traveled after the vehicle starts, or the mileage already traveled after the thermal management system starts; the driving time includes: the driving time already traveled after the vehicle starts, or the driving time already traveled after the thermal management system starts.

[0139] In this embodiment, the vehicle's mileage can be the mileage already traveled since the vehicle started, or the mileage already traveled since the thermal management system started. The vehicle's mileage is the distance traveled during the current trip, not the total mileage, which can reduce the power consumption during the current trip. The vehicle's driving time can be the driving time already traveled since the vehicle started, or the driving time already traveled since the thermal management system started. The vehicle's driving time is the duration of the current trip, not the total driving time, which can reduce the power consumption during the current trip.

[0140] 202. When the values ​​of the vehicle's driving parameters are less than the first threshold or the vehicle's driving mode is the first driving mode, the vehicle control device controls the power of the vehicle's thermal management system to be lower than the second threshold.

[0141] The first threshold can be a pre-set threshold. If the vehicle's driving parameters are lower than the first threshold, it indicates that the vehicle has traveled a short distance or for a short duration, suggesting that the trip was short-distance.

[0142] The second threshold can be a pre-set threshold. The thermal management system can operate at different power levels. If the power of the thermal management system is less than the second threshold, it indicates that the thermal management system is operating at a lower power level, which can reduce the vehicle's power consumption.

[0143] A thermal management system is a system used to manage the temperature of various components of a vehicle. For example, a thermal management system can be the thermal management system 30 described above. A thermal management system can include at least one of the following: an air conditioning system, a battery temperature control system, a seat heating device, or a contact heating device. The thermal management system can be used to control the temperature of the vehicle's air conditioning system, battery, steering wheel, seats, and fireplace.

[0144] In this embodiment, when the vehicle's driving parameters are low or the energy consumption level of the vehicle's driving mode is low, the thermal management system is controlled to operate at a lower power, thereby controlling the power of the thermal management system and preventing it from continuously operating at maximum power. This reduces the vehicle's power consumption, thereby increasing the vehicle's range and reducing unnecessary energy waste caused by short-distance travel.

[0145] In one possible implementation, the thermal management system operates in one of at least two modes, including a first mode and a second mode, wherein the power corresponding to the first mode is less than the power corresponding to the second mode.

[0146] In this embodiment, the power corresponding to the first mode can be either the average power or the maximum power of the first mode. The power corresponding to the second mode can be either the average power or the maximum power of the second mode. The power corresponding to the first mode being less than the power corresponding to the second mode can be either the maximum power of the first mode being less than the maximum power of the second mode, or the average power of the first mode being less than the average power of the second mode. The power ranges of the first mode and the second mode may or may not overlap; this embodiment does not impose any limitations on this.

[0147] When the thermal management system operates in the first mode, its power is the first power; when it operates in the second mode, its power is the second power. The first power is less than the second power. For example, when the thermal management system operates in the first mode, its power is below a second threshold; when it operates in the second mode, its power is greater than or equal to the second threshold. The first power can be greater than or equal to 0; when the first power is 0, the thermal management system is not activated.

[0148] In one possible implementation, when the vehicle's driving parameters include mileage, the vehicle's mileage belongs to one of at least two types of mileage, including a first mileage and a second mileage, wherein the value of the first mileage is less than the value of the second mileage, the first mileage corresponds to a first mode, and the second mileage corresponds to a second mode.

[0149] When the vehicle's driving parameters include driving time, the vehicle's driving time belongs to at least one of two driving times, including a first driving time and a second driving time. The value of the first driving time is less than the value of the second driving time. The first driving time corresponds to the first mode, and the second driving time corresponds to the second mode.

[0150] The first mileage value can be a specific mileage value or a mileage range. The second mileage value can also be a specific mileage value or a mileage range. If both the first and second mileage values ​​are mileage ranges, the first mileage value being less than the second mileage value can be either the maximum value of the mileage range corresponding to the first mileage value being less than the maximum value of the mileage range corresponding to the second mileage value, or the median value of the mileage range corresponding to the first mileage value being less than the median value of the mileage range corresponding to the second mileage value.

[0151] The first driving time can be a specific duration or a time interval. The second driving time can also be a specific duration or a time interval. If both the first and second driving times are time intervals, the first driving time being less than the second driving time can be due to either the maximum value of the first driving time interval being less than the maximum value of the second driving time interval, or the median value of the first driving time interval being less than the median value of the second driving time interval.

[0152] In one possible implementation, after the vehicle control device acquires the vehicle's driving parameters, it determines the operating mode of the thermal management system based on the vehicle's driving parameters.

[0153] The vehicle control unit determines the operating mode of the thermal management system based on the vehicle's driving parameters, which can be achieved in the following three ways.

[0154] Method 1: There is a first correspondence between the vehicle's driving parameters and the operating mode of the thermal management system. The vehicle control device acquires the vehicle's driving parameters and determines the operating mode of the thermal management system based on the driving parameters and this first correspondence.

[0155] In this embodiment of the application, the first correspondence is used to indicate the correspondence between at least two sets of driving parameters and at least two modes. The driving parameters of the vehicle belong to one of the at least two sets of driving parameters, the working mode of the thermal management system belongs to one of the at least two modes, the values ​​of any two sets of driving parameters are different, and the power corresponding to any two modes is different.

[0156] The first correspondence can be stored in the memory of the vehicle control device (e.g., non-volatile memory). The values ​​of any two of the at least two sets of driving parameters are different, and the values ​​of the at least two sets of driving parameters can cover the possible values ​​of the vehicle's driving parameters. When the values ​​of the vehicle's driving parameters change dynamically, each driving parameter can belong to one of the at least two sets of driving parameters. The vehicle control device can determine the mode corresponding to the vehicle's driving parameters based on the first correspondence and the vehicle's driving parameters, and can quickly determine the operating mode of the thermal management system based on the first correspondence and the vehicle's driving parameters.

[0157] When the vehicle's driving parameters include the vehicle's mileage, at least two sets of driving parameters include at least two types of mileage, and each set of driving parameters may include one type of mileage; when the vehicle's driving parameters include the vehicle's driving time, at least two sets of driving parameters include at least two types of driving time, and each set of driving time may include one type of driving time; when the vehicle's driving parameters include both the vehicle's mileage and driving time, at least two sets of driving parameters include at least two types of mileage and at least two types of driving time, and each set of driving parameters may include one type of mileage and one type of driving time.

[0158] Optionally, the first correspondence is preset, and the working mode of the thermal management system can be quickly determined based on the first correspondence and the vehicle's driving parameters.

[0159] In Method 1, the vehicle control device determines the operating mode of the thermal management system based on the vehicle's driving parameters and the first correspondence, as can be seen in any of the following three examples.

[0160] Example 1: When the vehicle's driving parameters include mileage, a first correspondence is used to indicate the correspondence between at least two mileage ranges and at least two driving modes. The at least two mileage ranges include either the first mileage or the second mileage, and the at least two driving modes include the first mode and the second mode. The first mileage corresponds to the first mode, and the second mileage corresponds to the second mode. If the vehicle's mileage is the first mileage, the vehicle control device determines that the thermal management system operates in the first mode, and the power of the thermal management system is below a second threshold. If the vehicle's mileage is the second mileage, the vehicle control device determines that the thermal management system operates in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0161] When the vehicle's driving parameters include its mileage, the first correspondence exists in tabular form, as shown in Table 1. Table 1 is a correspondence table for at least two types of mileage and at least two driving modes.

[0162] Table 1

[0163] mileage model Power corresponding to the mode Mileage 1 Mode 1 P1 Mileage 2 Mode 2 P2 Mileage 3 Mode 3 P3

[0164] As shown in Table 1, if the vehicle's mileage is mileage 1, then the mode corresponding to mileage 1 is mode 1, and the power corresponding to mode 1 is P1. If the vehicle's mileage is mileage 2, then the mode corresponding to mileage 2 is mode 2, and the power corresponding to mode 2 is P2. If the vehicle's mileage is mileage 3, then the mode corresponding to mileage 3 is mode 3, and the power corresponding to mode 3 is P3. Wherein, P1 < P2 < P3.

[0165] In this context, mileage 1 can be a specific mileage value (e.g., 8 kilometers) or a mileage range (e.g., 5-10 kilometers). Similarly, mileage 2 and mileage 3 can also be specific mileage values ​​or mileage ranges; this embodiment does not impose any limitations. P1 can be a specific power value or a power range. Similarly, P2 and P3 can also be specific power values ​​or power ranges; this embodiment does not impose any limitations. Table 1 can be stored in the memory of the vehicle control device (e.g., non-volatile memory).

[0166] In one possible example, mileage 1 is (0, 5], mileage 2 is (5, 10], and mileage 3 is (10, +∞), all in kilometers. For instance, if the vehicle's mileage is 3 kilometers, it belongs to mileage 1, and the corresponding thermal management system operates in mode 1. If the vehicle's mileage is 8 kilometers, it belongs to mileage 2, and the corresponding thermal management system operates in mode 2. If the vehicle's mileage is 15 kilometers, it belongs to mileage 3, and the corresponding thermal management system operates in mode 3.

[0167] Table 1 is an example of a possible correspondence between at least two driving ranges and at least two driving modes. The number of at least two driving ranges and the number of at least two driving modes can be flexibly set as needed, and this embodiment does not impose any limitations.

[0168] In this embodiment of the application, the vehicle control device can determine the working mode of the thermal management system corresponding to the vehicle's mileage based on Table 1 and the vehicle's mileage, and can quickly determine the working mode of the thermal management system based on the first correspondence and the vehicle's mileage.

[0169] Example 2: When the vehicle's driving parameters include driving duration, a first correspondence is used to indicate the correspondence between at least two driving durations and at least two driving modes. The at least two driving durations include either the first driving duration or the second driving duration mentioned above, and the at least two driving modes include the first driving mode and the second driving mode mentioned above. The first driving duration corresponds to the first driving mode, and the second driving duration corresponds to the second driving mode. If the vehicle's driving duration falls within the first driving duration, the vehicle control device determines that the thermal management system operates in the first driving mode, and the power of the thermal management system is below a second threshold. If the vehicle's driving duration falls within the second driving duration, the vehicle control device determines that the thermal management system operates in the second driving mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0170] When the vehicle's driving parameters include the vehicle's driving time, the first correspondence exists in tabular form, as shown in Table 2. Table 2 is a correspondence table for at least two driving times and at least two driving modes.

[0171] Table 2

[0172] driving time model Power corresponding to the mode Duration 1 Mode 1 P1 Duration 2 Mode 2 P2 Duration 3 Mode 3 P3

[0173] As shown in Table 2, if the vehicle's driving time is duration 1, then the mode corresponding to duration 1 is mode 1, and the power corresponding to mode 1 is P1. If the vehicle's driving time is duration 2, then the mode corresponding to duration 2 is mode 2, and the power corresponding to mode 2 is P2. If the vehicle's driving time is duration 3, then the mode corresponding to duration 3 is mode 3, and the power corresponding to mode 3 is P3. Wherein, P1 < P2 < P3.

[0174] In this context, duration 1 can be a specific duration value (e.g., 10 minutes) or a duration range (e.g., 8-15 minutes). Similarly, duration 2 and duration 3 can also be specific duration values ​​or duration ranges; this embodiment does not impose any limitations. P1 can be a specific power value or a power range. Similarly, P2 and P3 can also be specific power values ​​or power ranges; this embodiment does not impose any limitations. Table 2 can be stored in the memory of the vehicle control device (e.g., non-volatile memory).

[0175] In one possible example, duration 1 is (0, 8], duration 2 is (8, 15], and duration 3 is (15, +∞), all in minutes. For instance, if the vehicle's travel time is 5 minutes, then the travel time belongs to duration 1, and the corresponding thermal management system operating mode is mode 1. If the vehicle's travel time is 10 minutes, then the travel time belongs to duration 2, and the corresponding thermal management system operating mode is mode 2. If the vehicle's travel time is 20 minutes, then the travel time belongs to duration 3, and the corresponding thermal management system operating mode is mode 3.

[0176] Table 2 is an example of a possible correspondence between at least two driving durations and at least two driving modes. The number of at least two driving durations and at least two driving modes can be flexibly set as needed, and this embodiment does not impose any limitations.

[0177] In this embodiment of the application, the vehicle control device can determine the working mode of the thermal management system corresponding to the vehicle's driving time based on Table 2 and the vehicle's driving time, and can quickly determine the working mode of the thermal management system based on the first correspondence and the vehicle's driving time.

[0178] Example 3: When the vehicle's driving parameters include mileage and driving time, the mileage belongs to at least two types of mileage, including a first mileage and a second mileage. Similarly, the driving time belongs to at least two types of driving times, including a first driving time and a second driving time. If either the mileage or the driving time is the first mileage or the first driving time, the vehicle's driving parameters correspond to the first mode. If both the mileage and the driving time are the second mileage or the second driving time, the vehicle's driving parameters correspond to the second mode.

[0179] In this embodiment, there is a first correspondence between the vehicle's driving parameters and the operating mode of the thermal management system. The vehicle control device can determine the operating mode of the thermal management system based on the vehicle's driving parameters and this first correspondence.

[0180] For example, when the vehicle's driving parameters include mileage and driving time, a first correspondence is used to indicate the correspondence between at least two mileages and at least two driving modes, and to indicate the correspondence between at least two driving times and at least two driving modes. The at least two mileages include the aforementioned first mileage or the aforementioned second mileage; the at least two driving times include the aforementioned first driving time or the aforementioned second driving time; and the at least two driving modes include the aforementioned first mode and the aforementioned second mode. The first mileage corresponds to the first mode, and the second mileage corresponds to the second mode. The first driving time corresponds to the first mode, and the second driving time corresponds to the second mode. If the vehicle's mileage is the first mileage and the vehicle's driving time is the first driving time, then the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is lower than a second threshold. If the vehicle's mileage is the first mileage and the vehicle's driving time is the second driving time, then the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is lower than the second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the first driving time range, the vehicle control unit determines that the thermal management system is operating in the first mode, and the power of the thermal management system is lower than the second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the second driving time range, the vehicle control unit determines that the thermal management system is operating in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0181] In this embodiment, the driving parameters of the vehicle correspond to the mode with the lowest power among the modes corresponding to driving mileage and driving time, which can reduce the power consumption of the vehicle and thus improve the driving range of the vehicle.

[0182] Optionally, if the vehicle's mileage falls within a first mileage range and the vehicle's driving time falls within a second driving time range, the vehicle control device determines that the thermal management system operates in a second mode, and the power of the thermal management system is greater than or equal to a second threshold. If the vehicle's mileage falls within the second mileage range and the vehicle's driving time falls within the first driving time range, the vehicle control device determines that the thermal management system operates in a second mode, and the power of the thermal management system is greater than or equal to a second threshold.

[0183] In this embodiment, the driving parameters of the vehicle correspond to the mode with the highest power among the modes corresponding to driving mileage and driving time, which can improve the user's travel experience.

[0184] When the vehicle's driving parameters include mileage and driving time, the first correspondence exists in tabular form, as shown in Table 3. Table 3 is a table showing the correspondence between at least two types of mileage, at least two types of driving time, and at least two driving modes.

[0185] Table 3

[0186] mileage driving time model Power corresponding to the mode Mileage 1 Duration 1 Mode 1 P1 Mileage 2 Duration 2 Mode 2 P2 Mileage 3 Duration 3 Mode 3 P3

[0187] As shown in Table 3, if the vehicle's mileage is mileage 1 and the vehicle's driving time is duration 1, then the operating mode of the thermal management system corresponding to the vehicle's driving parameters is Mode 1, and the power corresponding to Mode 1 is P1. If the vehicle's mileage is mileage 2 and the vehicle's driving time is duration 2, then the operating mode of the thermal management system corresponding to the vehicle's driving parameters is Mode 2, and the power corresponding to Mode 2 is P2. If the vehicle's mileage is mileage 3 and the vehicle's driving time is duration 3, then the operating mode of the thermal management system corresponding to the vehicle's driving parameters is Mode 3, and the power corresponding to Mode 3 is P3. Wherein, P1 < P2 < P3.

[0188] Mileage 1, Mileage 2 and Mileage 3 have different values, as do Duration 1, Duration 2 and Duration 3.

[0189] In this context, mileage 1 can be a specific mileage value (e.g., 8 kilometers) or a mileage range (e.g., 5-10 kilometers). Similarly, mileage 2 and mileage 3 can also be specific mileage values ​​or mileage ranges. Duration 1 can be a specific duration value (e.g., 10 minutes) or a duration range (e.g., 8-15 minutes). Similarly, duration 2 and duration 3 can also be specific duration values ​​or duration ranges. P2 and P3 can also be specific power values ​​or power ranges; this embodiment does not impose any limitations. Table 3 can be stored in the memory of the vehicle control device (e.g., non-volatile memory).

[0190] For example, mileage 1 is (0, 5], mileage 2 is (5, 10], and mileage 3 is (10, +∞), all in kilometers. Duration 1 is (0, 8], duration 2 is (8, 15], and duration 3 is (15, +∞), all in minutes. For instance, if a vehicle's mileage is 3 kilometers and its duration is 5 minutes, then the mileage belongs to mileage 1, the duration belongs to duration 1, and the corresponding thermal management system operates in mode 1. If a vehicle's mileage is 8 kilometers and its duration is 10 minutes, then the mileage belongs to mileage 2, the duration belongs to duration 2, and the corresponding thermal management system operates in mode 2. If a vehicle's mileage is 15 kilometers and its duration is 20 minutes, then the mileage belongs to mileage 3, the duration belongs to duration 3, and the corresponding thermal management system operates in mode 3.

[0191] In Table 3, the first correspondence is used to indicate the correspondence between at least two mileage parameters and at least two modes, and to indicate the correspondence between at least two duration parameters and at least two modes. The vehicle control device determines the operating mode of the thermal management system based on the vehicle's driving parameters and the first correspondence. Specifically, this can be achieved in ways including but not limited to: the vehicle control device determines the mode corresponding to the vehicle's driving mileage based on the correspondence between at least two mileage parameters and at least two modes; the vehicle control device determines the mode corresponding to the vehicle's driving time based on the correspondence between at least two duration parameters and at least two modes; wherein, the operating mode of the thermal management system is the mode with the lowest power among the modes corresponding to the driving mileage and the modes corresponding to the driving time.

[0192] For example, mileage 1 is (0, 5], mileage 2 is (5, 10], and mileage 3 is (10, +∞), all in kilometers. Duration 1 is (0, 8], duration 2 is (8, 15], and duration 3 is (15, +∞), all in minutes. For instance, if a vehicle's mileage is 3 kilometers and its duration is 10 minutes, then the mileage belongs to mileage 1, the duration belongs to duration 2, the mode corresponding to the mileage is mode 1, and the mode corresponding to the duration is mode 2. Therefore, the thermal management system operates in the mode with the lowest power consumption between mode 1 and mode 2, i.e., mode 1. In this embodiment, the thermal management system operates in the mode with the lowest power consumption between the mode corresponding to the mileage and the mode corresponding to the duration, which can further reduce the power consumption of the thermal management system, thereby reducing the vehicle's power consumption and improving its driving range.

[0193] In this embodiment, the vehicle control device can determine the working mode of the thermal management system corresponding to the vehicle's driving parameters based on Table 3, the vehicle's mileage and driving time, and can quickly determine the working mode of the thermal management system based on the first correspondence and the vehicle's mileage and driving time.

[0194] In one possible example, the power of the thermal management system is positively correlated with the values ​​of the vehicle's driving parameters. When the values ​​of the vehicle's driving parameters are low, the thermal management system operates at a lower power; when the values ​​of the driving parameters are high, the thermal management system operates at a higher power. The power corresponding to the target mode can be dynamically adjusted according to the vehicle's driving parameters, thereby achieving dynamic regulation of the thermal management system's power, resulting in higher energy management efficiency and ultimately reducing the vehicle's power consumption.

[0195] Method 2: The vehicle control device acquires the vehicle's driving parameters and determines the operating mode of the thermal management system based on the driving parameters and corresponding thresholds.

[0196] In Method 2, the vehicle control device acquires the vehicle's driving parameters and determines the working mode of the thermal management system based on the driving parameters and corresponding thresholds. This can be done in any of the following three scenarios.

[0197] Scenario 1: When the vehicle's driving parameters include its mileage, the vehicle control unit acquires the mileage and determines the operating mode of the thermal management system based on the mileage, a first mileage threshold, and other relevant factors. The first mileage threshold can be a pre-set threshold. It can be stored in the vehicle control unit's memory (e.g., non-volatile memory). For example, the first mileage threshold could be set to 5 kilometers.

[0198] In one possible example, if the vehicle's mileage is less than a first mileage threshold, the thermal management system is determined to operate in mode 1; if the vehicle's mileage is greater than or equal to the first mileage threshold, the thermal management system is determined to operate in mode 2. The power output corresponding to mode 1 is less than the power output corresponding to mode 2.

[0199] In this embodiment of the application, after obtaining the vehicle's mileage, the vehicle's mileage can be compared with the first mileage threshold to determine the working mode of the thermal management system, which can quickly determine the working mode of the thermal management system.

[0200] When the vehicle's driving parameters include the vehicle's mileage, the aforementioned first threshold can be the aforementioned first mileage threshold.

[0201] In another possible example, when the vehicle's mileage is less than a first mileage threshold, the thermal management system is determined to operate in mode 1; when the vehicle's mileage is greater than or equal to the first mileage threshold and less than a second mileage threshold, the thermal management system is determined to operate in mode 2; and when the vehicle's mileage is greater than or equal to the second mileage threshold, the thermal management system is determined to operate in mode 3. The power corresponding to mode 1 is less than the power corresponding to mode 2, and the power corresponding to mode 2 is less than the power corresponding to mode 3. The first mileage threshold and the second mileage threshold can be stored in the memory of the vehicle control device (e.g., non-volatile memory). For example, the first mileage threshold can be set to 5 kilometers, and the second mileage threshold can be set to 10 kilometers.

[0202] In this embodiment of the application, after obtaining the vehicle's mileage, the vehicle's mileage can be compared with the first mileage threshold and the second mileage threshold to determine the working mode of the thermal management system, which can quickly determine the working mode of the thermal management system.

[0203] In scenario 2, when the vehicle's driving parameters include the vehicle's driving time, the vehicle control device obtains the vehicle's driving time and determines the operating mode of the thermal management system based on the driving time, a first duration threshold, and the parameters.

[0204] In one possible example, if the vehicle's driving time is less than a first duration threshold, the thermal management system is determined to operate in mode 1; if the vehicle's driving time is greater than or equal to the first duration threshold, the thermal management system is determined to operate in mode 2. The power output corresponding to mode 1 is less than the power output corresponding to mode 2.

[0205] In this embodiment of the application, after obtaining the vehicle's driving time, the driving time of the vehicle can be compared with the first time threshold to determine the working mode of the thermal management system, which can quickly determine the working mode of the thermal management system.

[0206] When the vehicle's driving parameters include the vehicle's driving time, the aforementioned first threshold can be the aforementioned first duration threshold.

[0207] In another possible example, if the vehicle's driving time is less than a first time threshold, the thermal management system is determined to operate in mode 1; if the vehicle's driving time is greater than or equal to the first time threshold and less than a second time threshold, the thermal management system is determined to operate in mode 2; and if the vehicle's driving time is greater than or equal to the second time threshold, the thermal management system is determined to operate in mode 3. The power corresponding to mode 1 is less than the power corresponding to mode 2, and the power corresponding to mode 2 is less than the power corresponding to mode 3.

[0208] In this embodiment of the application, after obtaining the vehicle's driving time, the size of the vehicle's driving time relative to the first time threshold and the second time threshold can be determined, thereby determining the working mode of the thermal management system, which can quickly determine the working mode of the thermal management system.

[0209] In scenario 3, when the vehicle's driving parameters include the vehicle's mileage and driving time, the vehicle control device acquires the vehicle's mileage and driving time, and determines the working mode of the thermal management system based on the mileage, driving time, first mileage threshold, and first duration threshold.

[0210] In one possible example, if the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is less than a first duration threshold, the thermal management system is determined to operate in mode 1; if the vehicle's mileage is greater than or equal to the first mileage threshold and the vehicle's driving time is greater than or equal to the first duration threshold, the thermal management system is determined to operate in mode 2. The power output corresponding to mode 1 is less than the power output corresponding to mode 2.

[0211] In one possible implementation, the thermal management system is determined to operate in Mode 1 when the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is greater than or equal to a first driving time threshold. Similarly, the thermal management system is determined to operate in Mode 1 when the vehicle's mileage is greater than or equal to the first mileage threshold and the vehicle's driving time is less than the first driving time threshold.

[0212] In another possible implementation, the thermal management system is determined to operate in mode 2 when the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is greater than or equal to a first driving time threshold. The thermal management system is also determined to operate in mode 2 when the vehicle's mileage is greater than or equal to the first mileage threshold and the vehicle's driving time is less than the first driving time threshold.

[0213] In this embodiment of the application, after obtaining the vehicle's mileage and driving time, it is possible to determine the size of the vehicle's mileage relative to a first mileage threshold and the size of the vehicle's driving time relative to a first driving time threshold, thereby determining the working mode of the thermal management system. This allows for the rapid determination of the working mode of the thermal management system.

[0214] In another possible example, if the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is less than a first duration threshold, the thermal management system is determined to operate in Mode 1. If the vehicle's mileage is greater than or equal to the first mileage threshold and less than a second mileage threshold, and the vehicle's driving time is greater than or equal to the first duration threshold and less than the second duration threshold, the thermal management system is determined to operate in Mode 2. If the vehicle's mileage is greater than or equal to the second mileage threshold and the vehicle's driving time is greater than or equal to the second duration threshold, the thermal management system is determined to operate in Mode 3. The power corresponding to Mode 1 is less than the power corresponding to Mode 2, and the power corresponding to Mode 2 is less than the power corresponding to Mode 3.

[0215] In one possible implementation, the thermal management system is determined to operate in Mode 1 when the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is greater than or equal to a first duration threshold and less than a second duration threshold. The thermal management system is also determined to operate in Mode 1 when the vehicle's mileage is greater than or equal to the first mileage threshold and less than the second mileage threshold, and the vehicle's driving time is less than the first duration threshold. The thermal management system is further determined to operate in Mode 2 when the vehicle's mileage is greater than or equal to the second mileage threshold and the vehicle's driving time is greater than or equal to the second duration threshold. The thermal management system is also determined to operate in Mode 1 when the vehicle's mileage is greater than or equal to the second mileage threshold and the vehicle's driving time is less than the first duration threshold.

[0216] In another possible implementation, when the vehicle's mileage is less than a first mileage threshold and the vehicle's driving time is greater than or equal to a first duration threshold and less than a second duration threshold, the thermal management system is determined to operate in mode 2. When the vehicle's mileage is greater than or equal to the first mileage threshold and less than the second mileage threshold, and the vehicle's driving time is less than the first duration threshold, the thermal management system is determined to operate in mode 2. When the vehicle's mileage is greater than or equal to the first mileage threshold and less than the second mileage threshold, and the vehicle's driving time is greater than or equal to the second duration threshold, the thermal management system is determined to operate in mode 3. When the vehicle's mileage is greater than or equal to the second mileage threshold, and the vehicle's driving time is greater than or equal to the first duration threshold and less than the second duration threshold, the thermal management system is determined to operate in mode 3. When the vehicle's mileage is less than the first mileage threshold and the vehicle's driving time is greater than or equal to the second duration threshold, the thermal management system is determined to operate in mode 3. When the vehicle's mileage is greater than or equal to the second mileage threshold and the vehicle's driving time is less than the first duration threshold, the thermal management system is determined to operate in mode 3.

[0217] In this embodiment of the application, after obtaining the vehicle's mileage and driving time, it is possible to determine the magnitude of the vehicle's mileage relative to the first mileage threshold and the second mileage threshold, and to determine the magnitude of the vehicle's driving time relative to the first driving time threshold and the second driving time threshold, thereby determining the working mode of the thermal management system. This allows for the rapid determination of the working mode of the thermal management system.

[0218] Method 3: The vehicle control device inputs the vehicle's driving parameters into the AI ​​model to obtain the working mode of the thermal management system.

[0219] The AI ​​model can learn the correspondence between driving parameters and the operating mode of the thermal management system. This AI model can be a trained model that can output the operating mode of the thermal management system based on the input driving parameters of the vehicle.

[0220] In this embodiment, the vehicle control device inputs the vehicle's driving parameters into the artificial intelligence (AI) model to obtain the working mode of the thermal management system. The working mode of the thermal management system can be quickly obtained based on the vehicle's driving parameters and the AI ​​model.

[0221] Optionally, the above driving parameters may also include road condition parameters. Road condition parameters may include at least one of the following: whether the road surface is icy, whether the road surface is wet, whether the road surface is bumpy, and whether there is traffic congestion.

[0222] In this embodiment, the driving parameters may also include road condition parameters, thereby taking into account the impact of road condition parameters on the working mode of the thermal management system, thus conforming to actual vehicle usage scenarios and improving the reliability of the working mode of the thermal management system output by the AI ​​model.

[0223] In one possible implementation, after the vehicle control device acquires the vehicle's driving mode, the vehicle control device determines the operating mode of the thermal management system based on the vehicle's driving mode.

[0224] The vehicle control unit determines the operating mode of the thermal management system based on the vehicle's driving mode, which can be achieved in the following ways.

[0225] There is a second correspondence between the vehicle's driving mode and the operating mode of the thermal management system. The vehicle control device acquires the vehicle's driving mode, and determines the operating mode of the thermal management system based on the vehicle's driving mode and this first correspondence.

[0226] For example, the second correspondence is used to indicate the correspondence between at least two driving modes and at least two modes. The at least two driving modes include either the first driving mode or the second driving mode described above, and the at least two modes include both the first mode and the second mode described above, with the first driving mode corresponding to the first mode and the second driving mode corresponding to the second mode. If the vehicle's driving mode is the first driving mode, the vehicle control device determines that the thermal management system is operating in the first mode, and the power of the thermal management system is below a second threshold. If the vehicle's driving mode is the second driving mode, the vehicle control device determines that the thermal management system is operating in the second mode, and the power of the thermal management system is greater than or equal to the second threshold.

[0227] The second correspondence can exist in tabular form, as shown in Table 4. Table 4 is a table showing the correspondence between at least two driving modes and at least two modes.

[0228] Table 4

[0229] Driving Mode model Power corresponding to the mode Driving Mode 1 Mode 1 P1 Driving Mode 2 Mode 2 P2 Driving Mode 3 Mode 3 P3

[0230] As shown in Table 4, if the vehicle's driving mode is driving mode 1, then the corresponding mode is Mode 1, and the power corresponding to Mode 1 is P1. If the vehicle's driving mode is driving mode 2, then the corresponding mode is Mode 2, and the power corresponding to Mode 2 is P2. If the vehicle's driving mode is driving mode 3, then the corresponding mode is Mode 3, and the power corresponding to Mode 3 is P3. Wherein, P1 < P2 < P3.

[0231] Here, P1 can be a specific power value or a power range. Similarly, P2 and P3 can also be specific power values ​​or power ranges, and this application embodiment does not limit them. Table 1 can be stored in the memory of the vehicle control device (e.g., non-volatile memory).

[0232] In one possible example, driving mode 1 is eco mode, driving mode 2 is standard mode, and driving mode 3 is sport mode. For instance, if the vehicle's driving mode is eco mode, the corresponding thermal management system operates in mode 1. If the vehicle's driving mode is standard mode, the corresponding thermal management system operates in mode 2. If the vehicle's driving mode is sport mode, the corresponding thermal management system operates in mode 3.

[0233] Table 4 is an example of a table showing at least two possible driving modes and their corresponding relationships. The number of at least two driving modes and the number of at least two modes can be flexibly set as needed, and this embodiment does not impose any limitations.

[0234] In this embodiment, the vehicle control device can determine the operating mode of the thermal management system corresponding to the vehicle's driving mode based on Table 4 and the vehicle's driving mode, and can quickly determine the operating mode of the thermal management system based on the second correspondence and the vehicle's driving mode.

[0235] In one possible implementation, after the vehicle control device acquires the vehicle's driving parameters and driving mode, it determines the operating mode of the thermal management system based on the vehicle's driving mode.

[0236] The vehicle control unit determines the operating mode of the thermal management system based on the vehicle's driving parameters and driving mode, which can be achieved in the following ways.

[0237] There is a first correspondence between the vehicle's driving parameters and the operating mode of the thermal management system. The vehicle control device acquires the vehicle's driving parameters and determines the corresponding mode based on the driving parameters and this first correspondence.

[0238] There is a second correspondence between the vehicle's driving mode and the operating mode of the thermal management system. The vehicle control device acquires the vehicle's driving mode, and determines the mode corresponding to the vehicle's driving mode based on the first correspondence.

[0239] The vehicle control unit determines the operating mode of the thermal management system based on the mode corresponding to the vehicle's driving parameters and the mode corresponding to the vehicle's driving mode.

[0240] Specifically, the vehicle control device determines the mode corresponding to the vehicle's driving parameters based on the vehicle's driving parameters and the first correspondence. The vehicle control device also determines the mode corresponding to the vehicle's driving mode based on the vehicle's driving mode and the first correspondence. These details can be found in the above embodiments and will not be repeated here.

[0241] The vehicle control device determines the operating mode of the thermal management system based on the mode corresponding to the vehicle's driving parameters and the mode corresponding to the vehicle's driving mode. This can be achieved through any of the following methods.

[0242] Method 1: The thermal management system can operate in the mode corresponding to the vehicle's driving parameters or the mode corresponding to the vehicle's driving mode, which is the mode with the lowest power consumption, thereby reducing the vehicle's power consumption.

[0243] Alternatively, the thermal management system can operate in the mode that corresponds to the vehicle's driving parameters or the mode with the highest power output, thereby improving the user's riding experience.

[0244] Method 3: The vehicle control unit determines the operating mode of the thermal management system based on the priority of driving parameters and the priority of the driving mode. Specifically, if the priority of the driving parameters is greater than the priority of the driving mode, the thermal management system operates in the mode corresponding to the driving parameters. If the priority of the driving parameters is less than the priority of the driving mode, the thermal management system operates in the mode corresponding to the driving mode.

[0245] The priority of driving parameters can be determined based on either the method of obtaining the driving parameters or the value of the driving parameters.

[0246] For example, driving parameters determined based on the vehicle's navigation information have a higher priority than driving parameters determined based on the vehicle's wheel speed sensors and / or timers. The lower the value of a driving parameter, the higher its priority.

[0247] The priority of driving modes can be determined based on either the setting method of the driving mode or the energy consumption level of the driving mode.

[0248] For example, the driving mode set by the user has a higher priority than the driving mode recommended to the user based on their driving habits. The driving mode recommended to the user based on their driving habits has a higher priority than the default driving mode. The lower the energy consumption level of a driving mode, the higher its priority.

[0249] In one possible implementation, the operating mode or power of the thermal management system can be determined in any of the following three ways.

[0250] (1) The vehicle control device determines the operating mode or power of the thermal management system based on the vehicle's driving parameters and / or the vehicle's driving mode.

[0251] (2) The working mode or power of the thermal management system is set by the user.

[0252] (3) The working mode or power of the thermal management system is determined by the thermal management system based on the ambient temperature and the temperature of the objects included in the thermal management system.

[0253] Method (1) can be found in the above embodiments.

[0254] In one possible implementation, the vehicle control method further includes: the vehicle control device determining the state of at least one of the following based on the vehicle's driving parameters: vehicle lights, windows, curtains, and sunroof.

[0255] The status of vehicle lights can include whether the vehicle lights are on and their power output. The status of vehicle windows can include whether the windows are open or closed. The status of the sunroof can include whether it is open or closed. The status of vehicle curtains can include whether they are open or closed.

[0256] When the vehicle's driving parameters are low, the status of the vehicle's lights, windows, curtains, and sunroof can be controlled to reduce the vehicle's power consumption.

[0257] Optionally, the power consumption of vehicle lights is positively correlated with the vehicle's driving parameters. The lower the values ​​of the vehicle's driving parameters, the lower the power consumption of the vehicle lights, which can reduce unnecessary energy waste caused by short-distance travel.

[0258] Optionally, when the vehicle's driving parameters are below a first threshold, the windows and sunroof can be kept closed. When the vehicle's mileage or travel time is short, keeping the windows and sunroof closed prevents them from affecting the cooling or heating performance of the thermal management system, thereby reducing vehicle power consumption and minimizing unnecessary energy waste during short trips.

[0259] Optionally, the curtains can be kept open when the outside temperature of the vehicle is lower than a first set temperature, the vehicle is exposed to sunlight, and the vehicle's driving parameters are below a first threshold. For example, in winter when there is sunlight and the vehicle needs heating, the curtains can be kept open when the vehicle's mileage or driving time is short, allowing sunlight to enter the vehicle and helping the interior temperature rise quickly, thereby reducing the vehicle's power consumption and minimizing unnecessary energy waste caused by short trips.

[0260] Optionally, the curtains can be kept closed when the outside temperature of the vehicle is higher than a second set temperature, the vehicle is exposed to sunlight, and the vehicle's driving parameters are below a first threshold. For example, in summer when there is sunlight and the vehicle needs cooling, the curtains can be kept closed when the vehicle's mileage or driving time is short to prevent sunlight from entering the vehicle and help the interior temperature drop quickly, thereby reducing the vehicle's power consumption and minimizing unnecessary energy waste caused by short trips.

[0261] The first threshold can be a preset threshold. The first set temperature is lower than the second set temperature.

[0262] In one possible implementation, the thermal management system includes at least one of the following: an air conditioner, a battery temperature control system, a seat heating device, and a contact heating device.

[0263] In this embodiment, the thermal management system can control the temperature set by the air conditioner, control the battery temperature through a battery temperature control system, control the seat temperature through a seat heating device, and control the temperature of the steering wheel, fireplace, etc., through a contact heating device, thereby controlling the temperature of the cooling or heating devices in the vehicle. For example, the thermal management system can control the temperature of these objects through water cooling, liquid cooling, air cooling, PTC heating, etc.

[0264] In one possible implementation, at least one object includes a first object and a second object, and the thermal management system is used to control the power corresponding to the first object and the power corresponding to the second object; the priority of the first object is greater than the priority of the second object, and the power corresponding to the first object is greater than the power corresponding to the second object.

[0265] In this embodiment, the thermal management system can control higher-priority objects to have higher power, thereby ensuring that the temperature of higher-priority objects is preferentially regulated, thus improving the cooling or heating effect of higher-priority objects. For example, in winter, when the vehicle battery has low remaining charge, the battery has higher priority, allowing it to have higher power and quickly raise its temperature to its optimal operating temperature range, thereby improving the battery's charging and discharging efficiency. Similarly, in summer, when the battery has low remaining charge, the battery has higher priority, allowing it to have higher power and quickly lower its temperature to its optimal operating temperature range, thereby improving the battery's charging and discharging efficiency. The optimal operating temperature range of the battery can be preset. The optimal operating temperature range of the battery is related to the battery type and chemical characteristics.

[0266] above Figure 2 Several possible implementation methods are introduced below, in conjunction with... Figure 3 and Figure 4This section introduces some possible implementation methods. The following... Figure 3 and Figure 4 For any unexplained meanings or logic in the illustrated embodiments, please refer to the preceding description.

[0267] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating another vehicle control method provided in an embodiment of this application. Figure 3 As shown, this vehicle control method is applied to the aforementioned vehicle system 100, for example, executed by the vehicle control device 10. The vehicle control method includes steps 301 to 303. The order of steps presented here is merely an example; the embodiments of this application are also applicable to other order of step execution, multiple executions of one or more steps, etc.

[0268] 301. The vehicle control device obtains the vehicle's mileage and driving time, and obtains the vehicle's driving mode.

[0269] Driving modes can include any of the following: Eco mode, Standard mode, Sport mode, Snow mode, and Mountain mode. The driving mode selected by the user can be the user's current driving mode, the default driving mode, or a driving mode recommended based on the user's driving habits.

[0270] 302. When the vehicle's mileage is less than a first mileage threshold, or the vehicle's driving time is less than a first driving time threshold, and the vehicle's driving mode is the first driving mode, the vehicle control device controls the thermal management system to operate in the first mode.

[0271] The first duration threshold and the second duration threshold can be found in the description of the above embodiments.

[0272] 303. When the vehicle's mileage exceeds the first mileage threshold, the vehicle's driving time exceeds the first driving time threshold, and the vehicle's driving mode is the second driving mode, the vehicle control device controls the thermal management system to operate in the second mode.

[0273] For example, the first driving mode can be the energy-saving mode, and the second driving mode can be the standard mode.

[0274] In this embodiment, after the user selects a driving mode, the working mode of the thermal management system can be dynamically adjusted according to the vehicle's mileage and driving time, as well as the vehicle's driving mode, in order to achieve higher energy management efficiency and reduce vehicle energy consumption.

[0275] Please see Figure 4 , Figure 4 This is a flowchart illustrating yet another vehicle control method provided in an embodiment of this application. Figure 4As shown, this vehicle control method is applied to the aforementioned vehicle system 100, for example, executed by the vehicle control device 10. The vehicle control method includes steps 401 to 404. The order of steps presented here is merely an example; the embodiments of this application are also applicable to other order of step execution, multiple executions of one or more steps, etc.

[0276] 401. After the vehicle is started, the vehicle control unit controls the thermal management system to operate in the first mode.

[0277] The first mode is the mode with the lowest power consumption among the operating modes of the thermal management system.

[0278] 402, The vehicle control device obtains the vehicle's mileage and driving time.

[0279] 403. When the vehicle's mileage is less than a first mileage threshold or the vehicle's driving time is less than a first duration threshold, the vehicle control device controls the thermal management system to operate in the first mode.

[0280] The first duration threshold and the second duration threshold can be found in the description of the above embodiments.

[0281] 404. When the vehicle's mileage exceeds the first mileage threshold and the vehicle's driving time exceeds the first duration threshold, the vehicle control device controls the thermal management system to operate in the second mode.

[0282] The power corresponding to the first mode is less than the power corresponding to the second mode. The first and second duration thresholds can be found in the description of the above embodiments.

[0283] The second mode can be a user-defined mode. Alternatively, the second mode can be a mode determined by the thermal management system based on the ambient temperature and the temperatures of the objects included in the thermal management system.

[0284] In this embodiment, after the vehicle starts, the vehicle's thermal management system can be set to operate in a first mode with the lowest power consumption by default, thereby reducing the vehicle's power consumption immediately after startup. If the vehicle's mileage exceeds a first mileage threshold and the vehicle's driving time exceeds a first duration threshold, the thermal management system can be reverted to a second mode. This embodiment can dynamically adjust the thermal management system's operating mode based on the vehicle's mileage and driving time to achieve higher energy management efficiency and reduce vehicle energy consumption.
