[0002] With the development of electric vehicle technology, range extended vehicles, which combine the advantages of electric drive and traditional internal combustion engines, are gaining more and more attention.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] To address the shortcomings of existing thermal management control technologies, such as poor adaptability to various scenarios and susceptibility to insufficient thermal management power and battery depletion, this application provides a vehicle thermal management control method that integrates thermal management control strategies with the vehicle's operating modes. This method enhances the adaptability of thermal management control to different scenarios and prevents issues like insufficient thermal management power and battery depletion.

[0038] Figure 1 This is a flowchart illustrating a vehicle thermal management control method provided in an embodiment of this application. This method can be applied to vehicles and is typically executed by a controller on the vehicle. This controller can be connected to the vehicle's thermal management controller and send control signals to the thermal management controller. This method can also be executed by one or more electronic devices such as servers, smartphones, and laptops. These devices are communicatively connected to the vehicle and, after executing this method, send control signals to the vehicle to control the thermal management system.

[0039] Furthermore, the execution subject of this method can be either hardware or software. When the execution subject is hardware, it can be one or more of the aforementioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the execution subject is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are made here.

[0040] like Figure 1 As shown, the method specifically includes:

[0041] Step 101: Determine at least one current operating mode of the target vehicle.

[0042] In some embodiments, the target vehicle is the vehicle for which this method applies, and the vehicle can be of various types, such as a range-extended vehicle. The vehicle's operating mode can be preset, and different operating modes can correspond to different application scenarios.

[0043] The at least one working mode can correspond to different working mode categories respectively. For example, the working mode categories can include a scenario mode category, a whole vehicle mode category, an energy source mode category, a driving mode category, and the like. The scenario mode category can include an indoor exhibition vehicle mode, an outdoor exhibition vehicle mode, a camping mode, a sleep mode, and the like. The whole vehicle mode category can include a normal control mode, a remote interaction mode, a direct current charging mode, an alternating current charging mode, and the like. The energy source mode category can include a pure electricity priority mode, a fuel priority mode, an automatic mode, and the like. The driving mode category can include an economy mode, a comfort mode, a sports mode, and the like.

[0044] In step 102, a target working mode that meets a preset thermal management high-power working start condition is determined from the at least one working mode.

[0045] In some embodiments, the thermal management high-power working start condition is a prerequisite for driving a high-power driving device included in a thermal management system on the target vehicle. The thermal management system is a system for adjusting the temperature of various temperature-controlled areas on the target vehicle. Generally, the thermal management system includes an electric motor control system, a battery system, a passenger cabin air conditioning system, and the like. The high-power driving device is a device in the thermal management system that needs to be driven with high power, i.e., a device whose power exceeds a preset power threshold, such as an air conditioner, a fan, and the like. The preset power threshold can be set in advance according to the power consumption of each device included in the thermal management system. For example, the power consumption of each device within a certain period of time can be counted to determine the proportion of each device in the total power consumption of the thermal management system, and a corresponding power can be calculated as the preset power threshold according to a set lower limit of the proportion. The device whose power exceeds the preset power threshold needs to obtain more power from the battery, and needs to limit the upper limit of the power of the thermal management system when the device is running. The thermal management high-power working start condition is related to the current state of the vehicle in the at least one working mode. For different working modes, a corresponding thermal management high-power working start condition can be set, and when the vehicle state in one or more working modes matches the vehicle state defined by the corresponding thermal management high-power working start condition, the one or more working modes are determined as the target working mode.

[0046] For example, if the at least one working mode includes a camping mode, i.e., the user selects and starts the camping mode when using the target vehicle as a camping vehicle, and the remaining fuel amount of the vehicle is greater than zero, it is determined that the thermal management high-power working start condition is met, and the camping mode is determined as the target working mode. For another example, if the at least one working mode includes a remote interaction mode, i.e., the user interacts with the vehicle remotely through a mobile phone or the like, and the remaining battery power is greater than 20%, it is determined that the thermal management high-power working start condition is met, and the remote interaction mode is determined as the target working mode.

[0047] Step 103, determining the thermal management power limit value corresponding to the target working mode.

[0048] In some embodiments, the correspondence between the thermal management power limit value and the target working mode can be pre-set. For example, a fixed thermal management power limit value corresponding to each working mode can be set, or a thermal management power limit value calculation formula corresponding to each working mode can be set, and the formula is used to calculate the vehicle state parameters in the target working mode to obtain the thermal management power limit value.

[0049] Step 104, generating a signal allowing the high-power driving device to operate, and limiting the operating power of the thermal management system to not exceed the thermal management power limit value.

[0050] In some embodiments, after determining the thermal management power limit value, the electronic device executing the method can send the thermal management power limit value to the thermal management controller on the target vehicle, and generate a signal allowing the high-power driving device to operate. If the current high-power driving device is not operating, the electronic device can send a thermal management high-power start signal to the thermal management system after detecting the signal, and the thermal management controller can control the high-power driving device included in the thermal management system to adjust the temperature inside the vehicle. During the operation of the high-power driving device of the thermal management system, the thermal management controller can adjust the overall working current, working voltage and other parameters of the thermal management system, so that the power of the thermal management system as a whole does not exceed the above-mentioned thermal management power limit value, and ensures the power supply stability and safety of the target vehicle. If the current high-power driving device is operating, the electronic device can keep the operating state of the high-power driving device unchanged after detecting the signal allowing the high-power driving device to operate.

[0051] The vehicle thermal management control method provided by the embodiments of the present application determines at least one working mode of the target vehicle, determines the target working mode that meets the thermal management high-power working start condition from the at least one working mode, determines the thermal management power limit value corresponding to the target working mode, and finally generates a signal allowing the high-power driving device to operate, and operates the thermal management system according to the thermal management power limit value. The embodiments of the present application combine the control strategy of the thermal management system with the working mode of the vehicle, so that the thermal management system can be adaptively controlled according to different working modes, thereby helping to avoid problems such as insufficient thermal management power and vehicle power shortage, and improving the energy utilization efficiency and scene adaptability of thermal management operation.

[0052] In some optional implementation manners, as shown in Figure 2 Step 102 includes:

[0053] Step 1021, determining the working mode category to which each working mode in the at least one working mode belongs.

[0054] The at least one working mode can correspond to different working mode categories respectively. For example, the working mode categories can include a scenario mode category, a whole vehicle mode category, an energy mode category, a driving mode category, and the like.

[0055] At step 1022, based on the order of the thermal management priorities of the working mode categories, it is determined whether the working mode with the highest thermal management priority among the at least one working mode meets the corresponding thermal management high-power working start condition.

[0056] Generally, different working mode categories correspond to different thermal management priorities. For example, the working mode categories arranged in descending order of the thermal management priorities are as follows: the scenario mode category, the whole vehicle mode category, the energy mode category, and the driving mode category. The energy mode category and the driving mode category represent that the thermal management priorities of the two categories are the same. According to the thermal management priorities of the working mode categories to which the working modes belong, the working mode with the highest thermal management priority can be determined, and then the thermal management high-power working start condition corresponding to the working mode is obtained to determine whether the state of the target vehicle meets the thermal management high-power working start condition.

[0057] At step 1023, if the working mode with the highest thermal management priority meets the corresponding thermal management high-power working start condition, the working mode with the highest thermal management priority is determined as the target working mode.

[0058] As an example, if the working mode with the highest thermal management priority is the camping mode in the scenario mode category, and the corresponding thermal management high-power working start condition is that the remaining fuel amount is greater than zero. If the remaining fuel amount in the fuel tank of the target vehicle is greater than zero, the camping mode is determined as the target working mode. That is, in the camping mode, the range extender can be started to generate electricity, so that the vehicle has the ability to maintain the power and prevent the battery from being depleted, and at this time, the thermal management system can be started.

[0059] It should be noted that if the working mode with the highest thermal management priority does not meet the corresponding thermal management high-power working start condition, it is determined that there is no target working mode that meets the thermal management high-power working start condition.

[0060] As an example, if the working mode with the highest thermal management priority is the camping mode, but the current remaining fuel amount is zero, it is determined that the current thermal management high-power working start condition is not met, that is, there is no target working mode. For another example, if the working mode with the highest thermal management priority is the indoor exhibition mode (the vehicle is parked indoors) in the scenario mode category, it is determined that the thermal management high-power working start condition is not met, that is, the indoor environment does not support starting the range extender, and the battery power cannot be maintained, and at this time, there is no target working mode.

[0061] The embodiment sets the thermal management priority of the working mode, realizes the thermal management high-power working start condition judgment of the working mode with high thermal management priority, avoids the conflict of starting thermal management between different working modes, and improves the accuracy of the timing and scene of starting the thermal management system.

[0062] In some optional implementations, as shown in Figure 3 Step 103 includes:

[0063] Step 1031, determining the available basic power of the battery of the target vehicle and the power generation of the range extender of the target vehicle.

[0064] The available basic power is the maximum power that the battery can provide except for the necessary power consumption. For example, the total power consumed by each power-consuming device can be collected, and then the available discharge power of the battery is subtracted from the total power consumed to obtain the available basic power.

[0065] The power generation of the range extender of the target vehicle can be calculated by collecting the bus current I GCU , bus voltage U GCU , that is, the power generation P GCU = I GCU * U GCU / 1000. Wherein, the unit of I GCU is A, the unit of U GCU is V, and the unit of P GCU is kW.

[0066] It should be noted that in some working modes, the range extender needs to be prohibited from starting (for example, in the sleep mode, in order to protect the safety of passengers, the range extender is prohibited from starting), and therefore the power generation at this time is 0.

[0067] Step 1032, calculating the available basic power and the power generation according to a preset thermal management power control strategy corresponding to the target working mode to obtain a thermal management power limit.

[0068] The thermal management power control strategy can be preset, and the parameters of the control strategy are related to the state of the target vehicle in the target working mode.

[0069] For example, the state parameters such as the remaining power of the target vehicle and the temperature in the target vehicle can have a corresponding relationship with the parameters of the thermal management power control strategy, and the corresponding relationship can be represented in the form of a table, a calculation formula, etc. Through the corresponding relationship, the parameter of the thermal management power control strategy corresponding to the current state parameter of the target vehicle can be determined.

[0070] As an example, the thermal management power control strategy is shown in the following formula (1):

[0071] P h =Min[a*(P b +b*P GCU ),15kW] (1)

[0072] wherein p h represents the thermal management power, P b represents the available base power, P GCU represents the power generation, 15kW represents the set upper limit power, which can be set arbitrarily according to the demand, Min[] represents the minimum value of each item in the brackets, and a and b are parameters of the thermal management control strategy.

[0073] After obtaining the parameters a, b, the available base power and the power generation, the thermal management power limit value can be calculated through formula (1).

[0074] The embodiment can realize accurate calculation of the thermal management power limit value for the target working mode by setting the thermal management power control strategy, so that the operation of the thermal management system can be accurately matched with the target working mode, thereby improving the scene adaptability of the operation of the thermal management system.

[0075] In some optional implementation manners, as shown in FIG. 10B, step 1031 includes: Figure 4

[0076] Step 10311, determining the available discharge power of the battery and the voltage conversion power of the target vehicle.

[0077] The available discharge power of the battery can be calculated by collecting the voltage and current of the output end of the battery. The voltage conversion power can be calculated by collecting the output voltage and current of the voltage conversion device (DC-DC device) on the vehicle. The voltage conversion device is used to convert the direct current voltage output by the battery to obtain the voltage required by each electrical device on the vehicle.

[0078] Step 10312, subtracting the voltage conversion power from the available discharge power to obtain the available base power.

[0079] Specifically, the formula for calculating the available base power is shown in formula (2) as follows:

[0080] P b =P BMSMAX -P DCDC (2)

[0081] wherein P BMSMAX is the available discharge power, and P DCDC is the voltage conversion power.

[0082] ​The embodiment can obtain the available basic power by calculating the available discharge power and voltage conversion power of the battery, accurately determine the power currently available for the target vehicle to support the operation of the thermal management system, and thus provide the thermal management system with electric energy according to the actual scene.

[0083] In some optional implementations, as shown in FIG. 10B, step 1032 includes: Figure 5

[0084] Step 10321, determining the remaining power of the battery.

[0085] Generally, the remaining power can be represented by the obtained SOC (State of Charge) value, that is, the percentage of the remaining power in the total power.

[0086] Step 10322, obtaining the target temperature set for the thermal management system and the actual temperature at a preset position on the target vehicle, and calculating the temperature difference between the target temperature and the actual temperature.

[0087] The target temperature is the expected temperature in the vehicle set by the user, and the preset position can be arbitrarily set. Generally, it can be the position of the seat in the vehicle close to the head of the passenger. For example, the temperature T1 near the head of the front seat and the temperature T2 near the head of the rear seat can be obtained, and then the average value of T1 and T2 is calculated as the actual temperature.

[0088] Since the thermal management system can work in a cooling or heating mode, the temperature difference can be the absolute value of the difference between the target temperature and the actual temperature.

[0089] Step 10323, determining the first parameter corresponding to the remaining power from a preset first parameter corresponding table, and determining the second parameter corresponding to the temperature difference from a preset second parameter corresponding table.

[0090] The first parameter corresponding table is a table representing the correspondence between the remaining power and the first parameter, and the second parameter corresponding table is a table representing the correspondence between the temperature difference and the second parameter.

[0091] When calibrating the first parameter corresponding table, calibration can be performed on the actual vehicle. Under the premise of ensuring the normal operation of the thermal management system, the first parameter is adjusted so that the power provided by the battery can meet the operation of the thermal management system, and the remaining power is maintained as much as possible, so as to obtain the first parameter corresponding to different remaining powers.

[0092] When calibrating the second parameter corresponding table, calibration can be performed on the actual vehicle. Under the condition of different temperature differences between the actual temperature and the target temperature, the second parameter is adjusted so that the temperature difference is quickly reduced to less than a certain temperature, so as to obtain the second parameter under different temperature difference conditions.​

[0093] At step 10324, the available base power and the generated power are calculated based on the first parameter and the second parameter to obtain the thermal management power limit.

[0094] The first parameter corresponds to the remaining power, and thus the first parameter can be used to limit the output power of the battery to ensure the basic performance of the vehicle. For example, as shown in the above formula (1), a is the first parameter. The second parameter corresponds to the temperature difference, and thus the second parameter can be used to meet the power requirement of the thermal management system. For example, as shown in the above formula (1), b is the second parameter, which is multiplied by the generated power to reflect the degree of influence of the generated power on the temperature difference. According to the first parameter and the second parameter, a formula as shown in formula (1) can be used to calculate the thermal management power limit. It should be noted that the formula shown in formula (1) is only one implementation of the thermal management power control strategy, and any method that uses the first parameter to limit the output power of the battery and uses the second parameter to reflect the degree of influence of the generated power on the temperature difference for thermal management power calculation is within the scope of the present embodiment.

[0095] The present embodiment determines the first parameter and the second parameter of the thermal management power control strategy by setting the first parameter corresponding table and the second parameter corresponding table, and can calculate the corresponding thermal management power limit according to the actual remaining power and the temperature difference of the target vehicle. The accuracy of the calculated thermal management power limit and the matching with the actual scene are higher.

[0096] In some optional implementations, the first parameter corresponding table includes a first power corresponding relationship table and a first temperature corresponding relationship table, and the second parameter corresponding table includes a second power corresponding relationship table and a second temperature corresponding relationship table.

[0097] Step 10323 can be performed according to the following two cases:

[0098] Case one, if the target working mode is a mode indicating that the target vehicle is parked outdoors, the parameter corresponding to the remaining power is determined as the first parameter from the preset first power corresponding relationship table, and the parameter corresponding to the temperature difference is determined as the second parameter from the first temperature corresponding relationship table.

[0099] The outdoor parking mode is various modes in the scenario of long-time parking of the vehicle outdoors. For example, the outdoor parking mode can include a camping mode, an exhibition vehicle mode, etc. The first power corresponding relationship table and the first temperature corresponding relationship table can be calibrated in advance in the outdoor parking mode.

[0100] As an example, a in the above formula (1) is the first parameter, and the first power corresponding relationship table is shown in Table 1 below:

[0101] Table 1

[0102] SOC a 10％ 0 20％ 0.8 30％ 0.9 40％ 1

[0103] In Table 1, as the remaining power increases, the value of a gradually increases, that is, the more the remaining power, the higher the power that the battery can provide to the thermal management system, so that the thermal management system can more efficiently adjust the temperature; the less the remaining power, the less power that the battery can provide to the thermal management system, reducing the risk of battery depletion.

[0104] Optionally, in Table 1, when the SOC is greater than 40%, a is 1.

[0105] In the above formula (1), b is a second parameter, T is an actual temperature, T m is a target temperature, |T-T m | is a temperature difference, and the first temperature correspondence table is shown in Table 2 as follows:

[0106] Table 2

[0107] |T-T m |]]> b |T-T m |≤5℃]]> 0.7 5°C < |T-T m |≤10°C 0.8 10 < |T-T m |]]> 0.9

[0108] In Table 2, the greater the temperature difference, the greater the value of the second parameter, indicating that a higher power can be obtained from the power generation power of the range extender to provide to the thermal management system, improving the temperature control efficiency of the thermal management system.

[0109] Case two, if the target working mode is not a mode indicating that the target vehicle is parked outdoors, first, from the at least two driving modes contained in the preset second power correspondence table, determine the first target field corresponding to the current driving mode of the target vehicle.

[0110] Wherein, the working mode is not a mode indicating that the target vehicle is parked outdoors, that is, the target vehicle may be in a driving state, at this time, the first parameter can be determined according to the driving mode. The second power correspondence table can be calibrated in advance under different driving modes. Different driving modes occupy different fields in the second power correspondence table.

[0111] As an example, a in the above formula (1) is a first parameter, and the second power correspondence table is shown in Table 3 as follows:

[0112] Table 3

[0113] SOC a (ECONOMY mode) a (COMFORT mode) a (SPORT mode) 5％ 0 0 0 10％ 0.5 0.6 0.7 20％ 0.8 0.8 0.9 40％ 1 1 1

[0114] In Table 3, each column corresponds to a driving mode, i.e., each column is a field, and in the same driving mode, the value of a gradually increases with the increase of the remaining power, i.e., the more the remaining power, the higher the power that the battery can provide to the thermal management system, so that the thermal management system can more efficiently adjust the temperature; the less the remaining power, the less the power that the battery can provide to the thermal management system, thereby reducing the risk of battery depletion. For the same remaining power, the more the driving mode is biased towards sports, the higher the power required by the thermal management system, and the larger the corresponding first parameter value.

[0115] Then, from the first target field, the parameter corresponding to the remaining power is determined as the first parameter.

[0116] For example, if the current driving mode is the economy mode, the column corresponding to the economy mode in the above Table 3 is the first target field, and if the current remaining power is 20%, the first parameter is 0.8.

[0117] Then, from the second temperature corresponding relationship table, the second target field corresponding to the current energy mode of the target vehicle is determined from the at least two energy modes included in the second temperature corresponding relationship table.

[0118] Wherein, the working mode is not a mode indicating that the target vehicle is parked outdoors, i.e., indicating that the target vehicle can be in a driving state, at which time the second parameter can be determined according to the energy mode. The second temperature corresponding relationship table can be calibrated in advance under different energy modes. Different energy modes occupy different fields in the second temperature corresponding relationship table.

[0119] As an example, b in the above formula (1) is the second parameter, and the second temperature corresponding relationship table is shown in Table 4 below:

[0120] Table 4

[0121] |T-T m |]]> b (BATTERY PRIORITY) b (AUTO) b (FUEL PRIORITY) |T-T m |≤5℃]]> 0.5 0.7 0.7 5°C < |T-T m |≤10°C 0.6 0.8 0.8 10 < |T-T m |]]> 0.7 0.8 0.9

[0122] In Table 4, each column corresponds to an energy mode, and the pure-electricity priority mode refers to that the vehicle preferentially uses the battery power to meet the driving demand and reduces the use of fuel as much as possible. When the battery power is reduced to a certain level (for example, 15%), the range extender is started to supply power. The fuel priority mode refers to that, in order to maintain the driving performance, when the battery power is lower than a certain level (for example, 70%), the range extender is started to supply power. The automatic mode refers to that the vehicle automatically switches between the pure-electricity driving and the fuel driving according to the current driving condition, the battery power and other factors. In Table 4, each column is a field, and in the same energy mode, as the temperature difference increases, the value of the second parameter gradually increases, indicating that a higher power can be obtained from the power generation of the range extender to provide the thermal management system, thereby improving the temperature control efficiency of the thermal management system. For the same temperature difference, the more the energy mode is biased towards the fuel, the higher the power that can be obtained from the range extender, and the greater the value of the second parameter. For the same row in Table 4, in the pure-electricity priority mode, the starting frequency of the range extender is low, and therefore, the value of the parameter b is small, and the power obtained by the thermal management system from the range extender is low. In the automatic mode and the fuel priority mode, the value of the parameter b is large, and the power obtained by the thermal management system from the range extender is high.

[0123] Finally, the parameter corresponding to the temperature difference is determined as the second parameter from the second target field.

[0124] For example, if the current energy mode is the pure-electricity priority, the column corresponding to the pure-electricity priority in Table 4 above is the second target field, and if the current temperature difference is 6℃, the first parameter is 0.6.

[0125] In this embodiment, by judging whether the vehicle is in an outdoor parking scene or a non-outdoor parking scene, the corresponding power-quantity corresponding relationship table and the temperature corresponding relationship table are obtained, so that the obtained parameter can be more matched with the actual scene of the vehicle, and the scene adaptability of the calculated thermal management power limit value is higher.

[0126] In some optional implementation manners, step 1022 can be performed as follows:

[0127] If the working mode with the highest thermal management priority is a mode representing that the target vehicle is parked outdoors in the scene mode category, when the remaining fuel quantity of the target vehicle is greater than the preset fuel quantity, the mode of parking outdoors is determined as the target working mode.

[0128] As an example, the scene mode can include an indoor exhibition vehicle mode, an outdoor exhibition vehicle mode, a camping mode, a sleep mode and the like. The camping mode and the outdoor exhibition vehicle mode above, that is, belong to the mode of parking outdoors. When the target vehicle is parked outdoors, the range extender can be started to generate power, and therefore, when a certain amount of fuel is determined to be remaining, the thermal management system can be started, the range extender can continuously charge the battery, and battery power loss can be avoided.

[0129] If the work mode with the highest thermal management priority is the sleep mode in the scenario mode category, the sleep mode is determined as the target work mode when the remaining power of the battery of the target vehicle is greater than or equal to a first preset power (for example, 20%).

[0130] The sleep mode is a work mode selected by a user in a sleep scenario in a vehicle, and in the sleep mode, each device on the target vehicle operates according to a preset state corresponding to the sleep mode. For example, in the sleep mode, the driving motor, the range extender, and the like on the target vehicle are set to be prohibited from starting, the vehicle door is prohibited from being unlocked from the outside, and only the functions such as the seat, the light, the audio and video entertainment, and the like are reserved. When the target vehicle is in the sleep mode, the passengers in the vehicle can sleep in the vehicle, and at this time, in order to ensure the safety of the passengers in the vehicle, the range extender is usually prohibited from starting. Therefore, it is necessary to determine that the remaining power is greater than or equal to the first preset power, and the starting of the thermal management mode is allowed. The first preset power can be a fixed value set in advance, or can be set by the user. Optionally, a range of adjustable remaining power can be set in advance, and the user can adjust the first preset power within the range.

[0131] If the work mode with the highest thermal management priority is the normal control mode in the vehicle mode category, the normal control mode is determined as the target work mode when the range extender of the target vehicle is in a startable state, or the remaining power is greater than or equal to a second preset power.

[0132] The vehicle mode category can include the normal control mode, the remote interaction mode, the direct current charging mode, the alternating current charging mode, and the like. The normal control mode is a mode selected by the target vehicle in a normal driving scenario, for example, in a non-charging state, when it is detected that the user sits in the driving seat and the vehicle is in a powered-on state, the vehicle can be automatically switched to the normal control mode. In the normal control mode, the user needs to enter the vehicle to start the range extender and other devices in the vehicle. At this time, if the range extender is in a startable state (the range extender is set to be in a startable state after the vehicle is powered on by the user entering the vehicle), the range extender can generate power to charge the battery, thereby avoiding the battery from being discharged. Alternatively, if the remaining power is greater than or equal to the second preset power, it is determined that the battery power is sufficient to supply the thermal management system at this time.

[0133] The second preset power can be the same as or different from the first preset power. For example, the second preset power is 20%. The second preset power can be a fixed value set in advance, or can be set by the user. Optionally, a range of adjustable remaining power can be set in advance, and the user can adjust the second preset power within the range.

[0134] If the work mode with the highest thermal management priority is the charging mode in the vehicle mode category, the charging mode is determined as the target work mode.

[0135] The charging mode is a mode selected by the target vehicle automatically when charging. The charging mode can include a direct current charging mode and an alternating current charging mode. In any charging mode, the thermal management system does not consume the battery power completely, and the thermal management system can be started at this time.

[0136] If the working mode with the highest thermal management priority is the remote interaction mode in the vehicle mode category, and the remaining power is greater than or equal to the third preset power, the normal control mode is determined as the target working mode.

[0137] The remote interaction mode is a mode in which the user interacts with the target vehicle through a mobile phone or the like. At this time, the range extender is usually not allowed to be started, and therefore, it is necessary to determine that the remaining power reaches a certain value to allow the thermal management mode to be started. The third preset power can be the same as or different from the first preset power and the second preset power. For example, the third preset power is 20%. The third preset power can be a fixed value set in advance or set by the user. Optionally, a range of the remaining power can be set in advance, and the user can adjust the third preset power within the range.

[0138] It should be understood that, since the working modes in the energy mode category and the driving mode category need to be started in the normal control mode in the vehicle mode category, the starting conditions of the thermal management high-power working mode in the energy mode category and the driving mode category are the same as the starting conditions of the thermal management high-power working mode in the normal control mode.

[0139] The embodiment makes the applicable scenarios of the thermal management system more specific by determining whether the starting conditions of the thermal management high-power working mode are met according to the state of the vehicle in various working modes, which helps to improve the scenario adaptability of the thermal management system control.
