[0002] The target new energy vehicles mainly obtain heat sources through active motor heating, motor waste heat, air heat source, electric heater and compressor heat generation.

[0059] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0060] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0061] The vehicle control method, vehicle control device, vehicle and readable storage medium provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0062] Among them, the vehicle control method can be applied to a terminal, and can be specifically executed by hardware or software in the terminal.

[0063] The terminal includes a portable communication device such as a mobile phone or a tablet computer. It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer.

[0064] In the following various embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse and a joystick.

[0065] An embodiment of the present application provides a vehicle control method, the execution subject of the vehicle control method may be a vehicle, or may be a vehicle control device arranged on the vehicle, or may also be a server electrically connected to the vehicle, or may also be a user terminal communicatively connected to the vehicle, including but not limited to a mobile terminal and a non-mobile terminal.

[0066] like Figure 1 As shown, the vehicle control method includes: step 110 and step 120.

[0067] The vehicle includes a compressor heating module, an electric motor active heating module, and a water heating module.

[0068] Among them, the compressor heating module is a module for controlling the compressor heating, and the compressor can be a heat pump compressor.

[0069] The motor active heating module is a module that controls the motor to perform active heating.

[0070] The water heating module is a module that controls the heating of the water heater.

[0071] like Figure 2 As shown, the compressor heating module can be connected to the motor active heating module through a nine-way water valve; the motor active heating module can be connected to the water heating module through a nine-way water valve.

[0072] Step 110: Obtain the user scenario corresponding to the vehicle;

[0073] In this step, the user scenario is the actual scenario in which the user uses the vehicle.

[0074] The user scenario may include at least one of a vehicle heating scenario, a charging scenario, and an on-the-go thermal management scenario.

[0075] Driving heating scenarios are scenarios where heating is required while the vehicle is driving, such as scenarios where the cabin needs to be heated, scenarios where the battery needs to be heated, and scenarios where both the cabin and the battery need to be heated.

[0076] The charging scenario is a scenario for charging a vehicle, and may include: a plug-in charging sub-scenario or a plug-in scheduled charging sub-scenario.

[0077] The on-the-go thermal management scenario is the heat management scenario during vehicle driving.

[0078] It is understandable that the user can control components at different positions of the vehicle and adjust the parameters of the corresponding components to make the vehicle enter different working scenarios.

[0079] Of course, different work scenarios can exist separately or at the same time.

[0080] For example, the user can turn on the vehicle and drive it to put the vehicle in a driving heating scenario; the user can insert a charging gun into the vehicle to enable the vehicle to handle the charging scenario.

[0081] For example, the user is in the driving heating scenario and the on-the-way heat management scenario at the same time. In the actual execution process, the user scenario corresponding to the vehicle at the current collection time can be obtained through the control instructions received by the vehicle.

[0082] It is understandable that in different user scenarios, the objects that need to be heated in the vehicle, the heating temperature, and the corresponding control logic may be different.

[0083] Step 120: Based on the user scenario, control the working state of at least one of the compressor heating module, the motor active heating module and the water heating module.

[0084] In this step, the compressor heating module may generate heat through a compressor, and the compressor may include a heat pump compressor.

[0085] The motor active heating module can increase the power loss of the winding coil by updating the direct-axis current and quadrature-axis current of the motor; at the same time, the battery water circuit and the motor water circuit are connected in series to transfer the waste heat of the motor to the battery water circuit for heating.

[0086] The water heating module can use water as the heat transfer medium, heat it electrically, and supply heat through forced circulation of a high-temperature water pump.

[0087] The working status includes: on state or off state.

[0088] It is understandable that in different user scenarios, the objects that need to be heated in the vehicle, the heating temperature and the corresponding control logic may be different, so the corresponding heating modules that need to be controlled may also be different.

[0089] For a certain user scenario, one or more modules can be controlled.

[0090] Different user scenarios may have different corresponding numbers of control modules and types of modules.

[0091] For different user scenarios, when controlling the same heating module, the corresponding control logic may also be different.

[0092] In the actual implementation process, the module to be controlled can be selected based on the specific situation of the user scenario, the scenario requirements and the working parameters; and from the selected modules, the controller opening and closing state can be further used to control one or more of the compressor heating module, the motor active heating module and the water heating module to be turned on or off, so that the vehicle can work normally in the required user scenario.

[0093] For example, when the user scenario is a vehicle heating scenario, the compressor heating module, the motor active heating module and the water heating module are controlled to be turned on at the same time.

[0094] For another example, when the user scenario is a charging scenario, the compressor heating module and the motor active heating module are controlled to be turned on.

[0095] According to the vehicle control method provided in the embodiment of the present application, by determining the user scenario corresponding to the current acquisition moment of the vehicle, the heating demand required in the user scenario is effectively determined; in different scenarios, based on the heating demand required by the corresponding user scenario, one or more of the compressor module, the motor active heating module and the water heating module are controlled to cope with a variety of user scenarios, not just a single user scenario; and based on different scenarios, different control methods are selected to reasonably adjust the heat to ensure the user's comfort during vehicle use and reduce energy consumption.

[0096] In some embodiments, step 120 may further include:

[0097] When the user scenario is a driving heating scenario, the compressor heating module and the motor active heating module are controlled to be turned on, and based on the heating object, the working state of the water heating module is controlled.

[0098] In this embodiment, the heating object is an object with heating demand in the vehicle heating scenario.

[0099] The heating object includes at least one of a cabin and a battery.

[0100] The cabin may be a passenger compartment of the vehicle.

[0101] The heating object can be determined by the control command received by the vehicle.

[0102] It is understandable that in the driving heating scenario, it can be the cabin heating, the battery heating, or the cabin and the battery heating at the same time.

[0103] It is understandable that the working state of the water heating module may be different depending on the heating object.

[0104] In the actual execution process, when the control instruction received by the vehicle determines that the current user scenario is a driving heating scenario, the compressor heating module and the motor active heating module of the vehicle are controlled to be turned on.

[0105] In the actual implementation process, the vehicle can be controlled to reach the required temperature in the driving heating scenario through feedforward control and proportional integral (PI) control.

[0106] In the actual implementation process, when the only heating object is the cabin, the heating method is that both the compressor and the motor active heating are turned on, and based on the data related to the cabin and certain judgment conditions, it is determined whether the water heating module needs to be controlled to be turned on.

[0107] Similarly, when the only heating object is a battery, the heating method is to turn on both the compressor and the motor active heating, and based on the battery-related data and certain judgment conditions, determine whether it is necessary to control the water heating module to turn on.

[0108] According to the vehicle control method provided in the embodiment of the present application, by determining the user scenario, multiple modules of the vehicle are controlled to make the vehicle at the required temperature; when it is determined that the user scenario is a driving heating scenario, the compressor heating module and the motor active heating module are controlled to turn on, and the actual situation of the heating object at the current collection moment is determined, and the water heating module is controlled to actively heat the vehicle through the compressor and the motor, and auxiliary heating is performed through the water heater, so as to effectively make the vehicle at the required temperature for the driving heating scenario, meet the user experience, improve the use comfort and reduce energy consumption, and effectively save energy.

[0109] In some embodiments, based on the heating object, controlling the working state of the water heating module may further include:

[0110] In the case where the heating object includes a cabin or a battery, obtaining at least one working parameter associated with the heating object;

[0111] When it is determined based on at least one operating parameter associated with the heating object that the first target condition is met, the water heating module is controlled to turn on.

[0112] In this embodiment, when the heating object is a cabin, at least one working parameter associated with the heating object may include: actual air outlet temperature of the cabin, compressor speed and other parameters, ambient temperature of the vehicle environment and water temperature of the warm air circuit.

[0113] When the heating object is a battery, the at least one operating parameter associated with the heating object may include: battery water temperature, compressor speed and other parameters, ambient temperature of the vehicle environment and heating circuit water temperature.

[0114] The actual air outlet temperature is the air outlet temperature of the cabin at the current collection time.

[0115] The compressor speed is the speed of the compressor at the current acquisition moment.

[0116] The ambient temperature is the ambient temperature of the environment where the vehicle is located at the current collection time.

[0117] The water temperature of the warm air circuit is the water temperature of the branch where the warm air circuit is located at the current collection moment.

[0118] like Figure 2 As shown, the water temperature of the warm air circuit is the water temperature of the branch where the warm air water pump is located.

[0119] During the actual implementation process, the actual air outlet temperature of the cabin, the ambient temperature and the water temperature of the warm air circuit can be collected through the temperature sensor, and the speed of the compressor can be obtained through the speed sensor.

[0120] Of course, the actual air outlet temperature of the cabin, the speed of the compressor, the ambient temperature of the vehicle's environment, and the water temperature of the heating circuit can also be obtained by other means.

[0121] The first target condition is the condition for turning on the water heating module when the heating object has a heating demand.

[0122] The first target condition can be set accordingly based on the heating object.

[0123] In some embodiments, when the heating object is a cabin, the first target condition may include:

[0124] The difference between the actual air outlet temperature of the cabin and the target air outlet temperature is lower than the first target value.

[0125] In other embodiments, when the heating object is a cabin or a cabin, the first target condition may include:

[0126] The difference between the ambient temperature of the environment in which the vehicle is located and the target ambient temperature is lower than the second target value.

[0127] In some embodiments, when the heating object is a battery, the first target condition may include:

[0128] The difference between the battery water temperature and the target battery water temperature is lower than a third target value.

[0129] In some embodiments, when the heating object is a cabin, when it is determined based on at least one working parameter associated with the heating object that the first target condition is met, controlling the water heating module to turn on may also include:

[0130] When the difference between the actual air outlet temperature of the cabin and the target air outlet temperature is lower than the first target value and the compressor speed meets the maximum compressor speed, the water heating module is controlled to turn on.

[0131] In this embodiment, the target air outlet temperature is the air outlet temperature that the cabin needs to reach.

[0132] The target air outlet temperature may be determined based on a control instruction received by the vehicle, or may be customized by the user, or may be determined based on actual execution conditions. The specific value of the target air outlet temperature is not limited in this application.

[0133] The first target value is a preset value for determining the degree of difference between the actual outlet air temperature and the target outlet air temperature.

[0134] The first target value may be user-defined or determined based on actual conditions, and this application does not limit this.

[0135] The maximum compressor speed is the maximum speed that the compressor of the vehicle can reach.

[0136] During the actual execution process, after obtaining the actual air outlet temperature and the compressor speed, the difference between the actual air outlet temperature and the target air outlet temperature is compared, and the relationship between the compressor speed and the maximum compressor speed at the current collection moment of the vehicle is compared. Based on the comparison result, it is determined whether to turn on the water heating module to meet the heating needs of the cabin.

[0137] For example, when it is determined that the actual air outlet temperature is 3 degrees lower than the target air outlet temperature and lasts for a certain period of time, and the compressor speed is the maximum compressor speed, it is determined to turn on the water heating module.

[0138] The certain duration can be customized based on actual execution conditions. For example, the certain duration can be 60 seconds, 80 seconds, or other values, which is not limited in this application.

[0139] In some embodiments, when the heating object is a cabin or a battery, when it is determined based on at least one working parameter associated with the heating object that the first target condition is met, controlling the water heating module to turn on may also include:

[0140] When the difference between the ambient temperature of the vehicle environment and the target ambient temperature is lower than the second target value, and the warm air circuit water temperature is lower than the target circuit water temperature, the water heating module is controlled to be turned on.

[0141] In this embodiment, the second target value is a preset value for determining the degree of difference between the ambient temperature and the target ambient temperature.

[0142] The second target value can be customized by the user or determined based on actual conditions, and this application does not limit this.

[0143] During the actual execution process, after obtaining the ambient temperature of the vehicle's environment and the water temperature of the warm air circuit, the difference between the ambient temperature and the target ambient temperature is compared, and the relationship between the water temperature of the warm air circuit and the target circuit water temperature is compared. Based on the comparison result, it is determined whether to turn on the water heating module to meet the heating needs of the cabin or battery.

[0144] For example, when the ambient temperature is lower than the target ambient temperature by -15 degrees and the water temperature of the warm air circuit is lower than 40 degrees, it is determined to turn on the water heating module.

[0145] In some embodiments, when the heating object is a battery, when it is determined based on at least one working parameter associated with the heating object that the first target condition is met, controlling the water heating module to turn on may also include:

[0146] When the difference between the battery water temperature and the target battery water temperature is lower than the third target value and the compressor speed meets the maximum compressor speed, the water heating module is controlled to turn on.

[0147] In this embodiment, the target battery water temperature is the water temperature that the battery needs to reach.

[0148] The target battery water temperature can be determined based on the control instructions received by the vehicle, or can be customized by the user, or can be determined by actual execution conditions. The specific value of the target air outlet temperature is not limited in this application.

[0149] The third target value is a preset value for determining the degree of difference between the battery water temperature and the target battery water temperature.

[0150] The third target value can be customized by the user or determined based on actual conditions, and this application does not limit this.

[0151] In the actual execution process, after obtaining the battery water temperature and the compressor speed, the difference between the battery water temperature and the target battery water temperature is compared, and the relationship between the compressor speed at the current acquisition moment of the vehicle and the maximum compressor speed is compared. Based on the comparison result, it is determined whether to turn on the water heating module to meet the heating needs of the battery.

[0152] For example, when it is determined that the battery water temperature is 3 degrees lower than the target battery water temperature and lasts for a certain period of time, and the compressor speed is the maximum compressor speed, it is determined to turn on the water heating module to meet the heating demand of the battery.

[0153] According to the vehicle control method provided in the embodiment of the present application, by obtaining the actual air outlet temperature of the cabin, the compressor speed, the ambient temperature of the vehicle's environment and the water temperature of the warm air circuit, the acquired data is compared with the given threshold value to determine whether to turn on the water heating module. Only when the active heating of the compressor and the motor cannot achieve the desired heating effect, auxiliary heating is performed through the water heating module, which effectively reduces energy consumption and saves energy.

[0154] In the actual implementation process, when it is determined that the user scenario is a driving heating scenario, different judgment methods can be selected to determine whether the water heating module needs to be turned on.

[0155] According to the vehicle control method provided in the embodiment of the present application, by acquiring the working parameters associated with the heating object and based on the correlation between the working parameters and the first target conditions corresponding to them, it is effectively determined whether the working parameters corresponding to the current collection moment meet the conditions for turning on the water heating module, and the heat of the vehicle is reasonably adjusted.

[0156] like Figure 6 As shown, in some embodiments, based on the heating object, controlling the working state of the water heating module may also include:

[0157] When the heating objects include the cabin and the battery, determine the priority of the cabin and the battery;

[0158] Based on the priority level, determine the corresponding allocation ratio of cabin and battery;

[0159] Based on the distribution ratio, the water heating module is controlled to distribute heat to the cabin and the battery.

[0160] In this embodiment, the heating objects include the cabin and the battery, and the cabin and the battery need to be heated at the same time.

[0161] The priority level is between cabin heating and battery heating.

[0162] The distribution ratio is the ratio of heat distribution to the cabin and the battery.

[0163] In some embodiments, when the heating object includes a cabin and a battery, determining the priority levels of the cabin and the battery may further include:

[0164] obtaining at least two of a battery temperature, a battery heating request, and a passenger compartment defrost request;

[0165] Priority is determined between passenger compartment heating and battery heating based on at least two of a battery temperature, a battery heating request, and a defrost request.

[0166] In this embodiment, the battery heating request is whether the battery needs to be heated.

[0167] The defrost request indicates whether the cabin needs to be defrosted.

[0168] It is understandable that whether a battery heating request and a defrost request are received can be determined by corresponding signals respectively.

[0169] In actual implementation, the battery temperature, the battery heating request and the defrost request may be obtained through corresponding sensors disposed on the vehicle or components receiving control instructions.

[0170] In actual implementation, when the battery temperature is greater than the first battery temperature and the battery receives a battery heating request, the priority level of the cabin is higher than the priority level of the battery.

[0171] In a case where the battery temperature is lower than the second battery temperature, the battery does not receive a battery heating request, and the cabin receives a defrost request, the priority level of the battery is higher than the priority level of the cabin.

[0172] The first battery temperature may be customized based on actual execution conditions. For example, the first battery temperature may be -18 degrees, -20 degrees, or other values, which are not limited in this application.

[0173] The second battery temperature may be customized based on actual execution conditions. For example, the second battery temperature may be -20 degrees, -22 degrees, or other values, which are not limited in this application.

[0174] Of course, there are other ways to determine the priority of cabins and batteries.

[0175] According to the vehicle control method provided in the embodiment of the present application, by obtaining the battery temperature, battery heating request and passenger compartment defrost request, the priority of the cabin and the battery is effectively determined, providing a reference factor for subsequent heat regulation.

[0176] Continue to refer Figure 6 In some embodiments, determining the allocation ratios of the cabin and the battery based on the priority levels may also include:

[0177] Obtaining the battery water temperature, and determining a target allocation threshold based on the priority level; the target allocation threshold includes: a first allocation threshold, a second allocation threshold, and a third allocation threshold;

[0178] When the actual air outlet temperature is not lower than the target air outlet temperature and the difference between the battery water temperature and the target battery water temperature is greater than the first allocation threshold, determining a first allocation ratio;

[0179] When the actual outlet air temperature is lower than the target outlet air temperature and the difference between the actual outlet air temperature and the target outlet air temperature is greater than a second allocation threshold, determining a second allocation ratio;

[0180] When the actual outlet air temperature is lower than the target outlet air temperature and the difference between the actual outlet air temperature and the target outlet air temperature is greater than a third allocation threshold, a third allocation ratio is determined.

[0181] In this embodiment, the target allocation threshold is a preset value determined based on the priority level to determine the allocation ratio.

[0182] It can be understood that the values ​​of the thresholds included in the target allocation threshold are different depending on the priority level.

[0183] The first allocation threshold, the second allocation threshold, and the third allocation threshold may be determined based on actual implementation conditions, and this application does not limit this.

[0184] The value of the third allocation threshold is smaller than the value of the second allocation threshold.

[0185] It is understandable that heat can be distributed through a three-way water valve.

[0186] In the actual implementation process, the opening ratio of the three-way water valve is 0-100, and the adjustment accuracy of the three-way water valve is 1%, among which, the first opening of the three-way water valve is 0, indicating that the water passing through the three-way water valve does not pass through the warm air circuit, the second opening of the three-way water valve is 95-100, indicating that all the water passing through the three-way water valve passes through the warm air, and the third opening of the three-way water valve is between 0-94, indicating that there is hot water in both the battery and the warm air circuit, and they are distributed in a certain proportion.

[0187] Continue to refer Figure 6 In the actual implementation process, the three-way water valve can ensure that heat is distributed to both the cabin and the battery based on the initial opening. At this time, the heat distributed based on the initial opening is biased towards the cabin, and the heat distributed to the battery is very small, for example, it may be 1% or 3%.

[0188] In the actual implementation process, the initial opening can be 94, 93 or other openings. The specific value can be determined based on the actual situation and is not limited in this application.

[0189] Then, heat is distributed based on the actual air outlet temperature and battery water temperature collected.

[0190] During the actual implementation process, when the priority level of the cabin is higher than the priority level of the battery, the target allocation thresholds can be determined to include: the first allocation threshold of 3 degrees, the second allocation threshold of 3 degrees, and the third allocation threshold of 2 degrees. When the actual air outlet temperature of the cabin is not lower than the target air outlet temperature, and the battery water temperature is 3 degrees lower than the target battery water temperature (ie, the first allocation threshold), the heat is distributed to the battery through the three-way water valve to achieve the first allocation ratio.

[0191] When the actual air outlet temperature is 3 degrees lower than the target air outlet temperature (ie, the second allocation threshold), heat is added to the cabin through the three-way water valve to achieve the second allocation ratio.

[0192] When the actual air outlet temperature is 2 degrees lower than the target air outlet temperature (ie, the third allocation threshold), the three-way water valve stops adjusting and is locked to achieve the third allocation ratio.

[0193] Based on the actual air outlet temperature and battery water temperature, the judgment process is repeated continuously to adjust the heat.

[0194] In the actual implementation process, when the battery priority is higher than the cabin priority, in order to ensure that the cabin has a certain temperature, the cabin outlet air temperature is also required to be at least 35 degrees when the battery is given priority. The control target of the compressor module is the target battery water temperature of the battery, and the water heating module also controls the target battery water temperature of the battery. The three-way water valve controls the passenger compartment outlet air temperature to be no less than 35 degrees through proportional adjustment.

[0195] When the battery priority is higher than the cabin priority, the target allocation thresholds can be determined to include: the first allocation threshold of 3 degrees, the second allocation threshold of 6 degrees, and the third allocation threshold of 5 degrees. When the actual air outlet temperature of the cabin reaches the target air outlet temperature (such as 40 degrees) and the battery water temperature is 3 degrees lower than the target battery water temperature (ie, the first allocation threshold), the three-way water valve is used to control the heat distribution to the battery to achieve the first allocation ratio.

[0196] When the actual air outlet temperature of the cabin is 6 degrees lower than the target air outlet temperature (ie, the second allocation threshold), heat is added to the cabin through the three-way water valve to achieve the second allocation ratio.

[0197] When the actual air outlet temperature of the cabin is 5 degrees lower than the target air outlet temperature (ie, the third distribution threshold), the three-way water valve stops adjusting and is locked to achieve the third distribution ratio.

[0198] When the passenger compartment air outlet temperature reaches the target value of 38 degrees (calibrated value) and the battery water temperature is 3 degrees lower than the target battery water temperature, the heat distribution to the battery side is repeatedly adjusted.

[0199] Based on the actual air outlet temperature and battery water temperature, the judgment process is repeated continuously to adjust the heat.

[0200] According to the vehicle control method provided in the embodiment of the present application, the target allocation threshold required for allocating heat to the water heating module is determined by the priority levels of the cabin and the battery, and the allocation ratios corresponding to the cabin and the battery are effectively determined based on the actual air outlet temperature of the cabin and the correlation between the battery water temperature and the threshold value corresponding to the cabin and the battery. The heat of the water heating module is reasonably allocated to the cabin and the battery, and this allocation method can ensure the temperature required by the user during driving, ensure the user's comfort, and enhance the user experience.

[0201] like Figure 6 As shown, when both the cabin and the battery have heating requests, the priority levels of the cabin and the battery are determined first.

[0202] When the cabin priority is high, the cabin heating temperature requirement is met first. At this time, the three-way water valve can ensure that the cabin and the battery are heated at the same time based on the initial opening 94, but the battery allocation ratio is very small, perhaps 1%.

[0203] When the cabin reaches the target air outlet temperature and lasts for 60 seconds, and the battery water temperature is 3 degrees lower than the target battery water temperature, the three-way water valve performs PI adjustment based on the deviation between the target battery water temperature and the actual collected battery water temperature to distribute heat to the battery.

[0204] It is understandable that during the adjustment process, it is necessary to avoid large fluctuations in the temperature of the cabin so as to avoid affecting the user's driving experience.

[0205] After PI adjustment, because heat is distributed to the battery, the actual air outlet temperature of the cabin may be 2 degrees lower than the target air outlet temperature. At this time, the three-way water valve can stop adjusting and be in a locked state.

[0206] When the actual air outlet temperature continues to decrease and the actual air outlet temperature of the cabin is 3 degrees lower than the target air outlet temperature, the three-way water valve performs PI adjustment based on the deviation between the actual air outlet temperature of the cabin and the target air outlet temperature to distribute heat to the cabin.

[0207] During the actual execution process, real-time judgment is made based on the actual air outlet temperature of the cabin and the heat is adjusted to meet the heating needs of the cabin and batteries.

[0208] Continue to refer Figure 6 When the battery has a higher priority than the cabin, the battery heating temperature requirement is met first, but it is still necessary to ensure that the passenger cabin has a certain air outlet temperature, namely the target air outlet temperature.

[0209] In the actual implementation process, the requested air outlet temperature and the target air outlet temperature of the cabin can be determined first, and based on the correlation between different requested air outlet temperatures and target air outlet temperatures, a specific heat distribution method can be determined.

[0210] When the battery is given priority and the requested air outlet temperature of the cabin is lower than the target air outlet temperature, the opening of the three-way water valve is PI controlled based on the deviation between the target air outlet temperature and the requested air outlet temperature of the cabin, giving priority to ensuring the heat of the cabin and allocating the remaining heat to the battery. At this time, the maximum opening limit of the three-way water valve can be 94. This adjustment method can avoid giving all the heat to the cabin, resulting in no heating flow to the battery.

[0211] It is understandable that the requested air outlet temperature may be a temperature instruction issued by the user through the air conditioner of the vehicle.

[0212] When the battery is given priority and the requested air outlet temperature of the cabin is higher than the target air outlet temperature, the three-way water valve is controlled based on the target air outlet temperature of the cabin, giving priority to ensuring the heat of the cabin and distributing the remaining heat to the battery. At this time, the maximum opening limit of the three-way water valve can be 94. This adjustment method can avoid allocating all heat to the cabin, resulting in a situation where the battery has no heat.

[0213] When the actual air outlet temperature of the cabin reaches the target air outlet temperature (such as 38 degrees) and remains at the actual air outlet temperature for 60 seconds, and the battery water temperature is 3 degrees lower than the target battery water temperature, the three-way water valve performs PI adjustment based on the target battery water temperature and the actual battery water temperature to distribute heat to the battery.

[0214] It is understandable that during this adjustment process, it is also necessary to avoid large fluctuations in the temperature of the cabin so as to avoid affecting the user's driving comfort.

[0215] After distributing heat to the battery, if the actual air outlet temperature of the cabin subsequently drops below 35 degrees, the three-way water valve will stop adjusting and remain locked.

[0216] When the actual air outlet temperature of the cabin continues to decrease, for example, when the actual air outlet temperature of the cabin is lower than 34 degrees, the three-way water valve performs PI adjustment based on the deviation between the actual air outlet temperature of the cabin and the target air outlet temperature, and continuously makes judgments based on the collected actual air outlet temperature of the cabin and the battery temperature, and distributes heat through the three-way water valve.

[0217] According to the vehicle control method provided in the embodiment of the present application, by determining the priorities of the cabin and the battery, different heat distribution methods are selected. When the cabin priority level is high and the battery priority level is high, the specific distribution ratio is determined based on the actual air outlet temperature, the battery water temperature and different target distribution thresholds, respectively, to reasonably distribute the heat of the water heating module to the cabin and the battery, thereby further reducing energy consumption while ensuring the comfort of the cabin.

[0218] In some embodiments, the motor active heating module includes a motor circuit module and a low-temperature heat dissipation module; controlling the compressor heating module and the motor active heating module to turn on may also include:

[0219] Control the motor circuit module to open;

[0220] Determining a target water temperature corresponding to the chiller based on at least one operating parameter corresponding to the vehicle;

[0221] Based on the target water temperature, the working state of the low-temperature heat dissipation module is controlled.

[0222] In this embodiment, at least one operating parameter corresponding to the vehicle is a parameter related to temperature during the driving process of the vehicle.

[0223] The target water temperature corresponding to the chiller is the outlet water temperature of the chiller.

[0224] During the actual execution process, the target water temperature corresponding to the chiller can be obtained from at least one operating parameter corresponding to the collected vehicle.

[0225] The low-temperature heat dissipation module is a module that dissipates heat through a low-temperature radiator.

[0226] In actual implementation, the target water temperature may be compared with the ambient temperature to control the working state of the low-temperature heat dissipation module.

[0227] like Figure 2 As shown, the working state of the low-temperature heat dissipation module can be controlled by the nine-way valve.

[0228] The nine-way valve can include six working modes, among which modules four and five can be used in heating conditions, and other modules can be used in cooling conditions, etc.

[0229] Among them, the connection method of each port in mode four is: 1-3, 4-2, 8-6, 5-7, 9 is not connected.

[0230] The connection method of each port in mode five is: 1-3, 4-2, 8-6, 5-9, 7 is blocked.

[0231] When the target water temperature is not lower than the ambient temperature, Figure 3As shown, the low-temperature heat dissipation module can be turned on through the nine-way valve control mode five, that is, the heat passing through the chiller passes through the radiator.

[0232] It can be understood that when the target water temperature corresponding to the chiller is not lower than the ambient temperature, the low-temperature heat dissipation module is controlled to be turned on to dissipate the heat.

[0233] If the target water temperature corresponding to the chiller is not lower than the ambient temperature and the low-temperature heat dissipation module is not turned on, then in this user scenario, it will not be able to absorb the heat from the environment and will lose heat.

[0234] In the actual implementation process, when the target water temperature corresponding to the chiller is lower than the ambient temperature, such as Figure 4 As shown, the nine-way valve can be used to control mode four, which is to close the low-temperature heat dissipation module, that is, the heat passing through the chiller does not pass through the radiator.

[0235] In the actual implementation process, Figure 2 , Figure 3 as well as Figure 4 The thermal management systems shown include: Figure 5 The front-end heat dissipation module shown includes a low-temperature radiator and a fan.

[0236] According to the vehicle control method provided in the embodiment of the present application, the working state of the low-temperature heat dissipation module is controlled by controlling the relationship between the target water temperature corresponding to the chiller and the ambient temperature when the motor circuit module is turned on. When the target water temperature corresponding to the chiller is not lower than the ambient temperature, the low-temperature heat dissipation module is turned on to absorb ambient heat, thereby effectively reducing heat loss.

[0237] In some embodiments, controlling the motor circuit module to start may further include:

[0238] Acquire at least one working parameter associated with the heating object;

[0239] Calculating a first target water temperature based on at least one operating parameter associated with the heating object;

[0240] Based on the first target water temperature, the motor is controlled to actively start heating.

[0241] In this embodiment, the at least one operating parameter may include: a temperature parameter and an energy consumption parameter.

[0242] For example, when the user scenario is a driving heating scenario and the heating object is a cabin, the working parameters may include data corresponding to parameters such as ambient temperature, air conditioning setting mode, vehicle speed, and energy consumption.

[0243] When the user scenario is a driving heating scenario and the heating object is a battery, the working parameters may include data such as ambient temperature, vehicle speed, and energy consumption.

[0244] The first target water temperature is the temperature with the lowest energy consumption during the heating process of the motor active heating module.

[0245] The first target water temperature can be obtained through the neural network model.

[0246] The first target water temperature may be a variable iteratively optimized temperature.

[0247] In the actual implementation process, when the vehicle leaves the factory, a relatively reasonable initial value can be given based on a certain working condition. The control software calculates the energy consumption of the heating system for each driving through the system heating energy consumption calculation module. The system heating energy consumption includes the active heating energy consumption of the motor, the energy consumption of the compressor, and the energy consumption of the positive temperature coefficient (PTC) heater. Through neural network self-learning and iteration, the motor active heating target water temperature with the lowest heating system energy consumption in the corresponding user scenario is obtained.

[0248] During the actual implementation process, the motor active heating module performs heating with the first target water temperature as the control target.

[0249] According to the vehicle control method provided in the embodiment of the present application, by inputting the data under the user scenario into the neural network model, the motor active heating target water temperature that minimizes the energy consumption of the heating system can be obtained, and the energy utilization rate of the vehicle can be effectively improved based on the target temperature.

[0250] In some embodiments, step 120 may further include:

[0251] When the user scenario is a charging scenario and / or an in-transit thermal management scenario, the operating state of the motor active heating module is controlled based on at least one operating parameter corresponding to the vehicle.

[0252] In this embodiment, the operating parameters are operating parameters corresponding to the vehicle in a charging scenario or operating parameters in an on-the-go thermal management scenario.

[0253] Working parameters may include: ambient temperature, motor water temperature, motor body temperature, charge state, and predicted time, etc.

[0254] The working states of the motor active heating module include: turning on the motor active heating module and turning off the motor active heating module.

[0255] In the actual implementation process, the corresponding working parameters of the vehicle can be obtained through sensors and other devices on the vehicle, so as to determine the working state of the motor active heating model based on the working parameters.

[0256] According to the vehicle control method provided in the embodiment of the present application, by determining the specific situation of the user scenario and based on the obtained working parameters of the vehicle, the working state of the motor active heating module is effectively controlled, and based on the real-time data of the vehicle, the heat is reasonably managed to improve the rationality of thermal management and reduce heat loss.

[0257] In some embodiments, when the user scenario is a charging scenario and / or a thermal management scenario in transit, controlling the working state of the motor active heating module based on at least one working parameter corresponding to the vehicle may also include:

[0258] When the user scenario is a charging scenario, a charging sub-scenario is determined; the charging sub-scenario includes a plug-in charging sub-scenario or a plug-in scheduled charging sub-scenario;

[0259] In the plug-in charging sub-scenario, and when it is determined based on at least one operating parameter that the second target condition is met, controlling the motor active heating module to turn on;

[0260] In the plug-in charging reservation sub-scenario, and when it is determined based on at least one operating parameter and the reservation information that the third target condition is met, the motor active heating module is controlled to turn on.

[0261] In this embodiment, the charging sub-scenario is one of the charging scenarios.

[0262] It is understandable that the operating parameters required to determine the conditions for starting the motor active heating module will be different depending on the charging sub-scenario.

[0263] When the charging sub-scenario is a plug-in charging sub-scenario, the operating parameters may include: state of charge, ambient temperature, motor water temperature, and motor body temperature.

[0264] When the charging sub-scenario is a plug-in scheduled charging sub-scenario, the working parameters may include: scheduled time, heating request, motor water temperature, and motor body temperature.

[0265] The second target condition is the condition that needs to be met for the motor active heating module to be turned on in the plug-in charging sub-scenario.

[0266] The second target condition may include a condition that the state of charge needs to meet, a condition that the ambient temperature needs to meet, a condition that the motor water temperature needs to meet, and a condition that the motor body temperature needs to meet.

[0267] The third target condition is the condition that needs to be met for the motor active heating module to be turned on in the plug-in scheduled charging sub-scenario.

[0268] During the actual execution process, when it is determined that the current user scenario is a charging scenario, and the charging sub-scenario is further determined to be a plug-in charging sub-scenario, when it is determined that the difference between the state of charge and the target state of charge is lower than a first value, the ambient temperature is lower than a second value, the motor water temperature is lower than a third value, and the motor body temperature is lower than a fourth value, the motor active heating module can be controlled to turn on.

[0269] For example, when it is determined that the difference between the current state of charge and the target state of charge of 90% is less than 1%, and the ambient temperature is less than 5 degrees, the motor water temperature is less than 10 degrees, and the motor body temperature is less than 70 degrees, the motor active heating module is controlled to turn on.

[0270] In the actual execution process, when it is determined that the current user scenario is a charging scenario, and the charging sub-scenario is further determined to be a plug-in appointment charging sub-scenario, when the cabin has a heating request and the motor body temperature is lower than the fourth value, it is determined to turn on the motor active heating module.

[0271] For example, 10 minutes before the user is about to use the car, the cabin is judged to have a heating request based on the cabin set temperature, and the motor water temperature and the motor body temperature are detected at the same time; if the cabin has a heating request and the motor body temperature is lower than 70 degrees, it is determined to turn on the motor active heating module.

[0272] It is understandable that turning on the motor active heating module can heat the motor water temperature to 20 degrees or the motor body temperature to 80 degrees. Meeting either of the two can ensure that during cold start driving, when the user turns on the air conditioner for heating, the heat pump can absorb heat from the motor circuit, saving energy while quickly heating up.

[0273] According to the vehicle control method provided in the embodiment of the present application, by determining the charging sub-scenario under the charging scenario, based on the working parameters required for the charging sub-scenario and the corresponding conditions, it is determined whether to turn on the motor active heating module, thereby effectively ensuring that during cold start driving, when the user turns on the air conditioner for heating, the heat pump can absorb heat from the motor circuit, saving energy while quickly heating up.

[0274] In some embodiments, when the user scenario is a charging scenario and / or a thermal management scenario in transit, controlling the working state of the motor active heating module based on at least one working parameter corresponding to the vehicle may also include:

[0275] When the user scenario is an on-the-go thermal management scenario, and when it is determined based on at least one operating parameter that a fourth target condition is satisfied, determining a target time for adjusting a temperature associated with the motor to a target temperature;

[0276] Based on the target time, the motor active heating module is controlled to turn on.

[0277] In this embodiment, when the user scenario is an on-the-go thermal management scenario, the operating parameters may include: ambient temperature, motor water temperature, and motor body temperature.

[0278] The fourth target condition is a condition for determining the start time of the motor active heating module.

[0279] The target temperature is the temperature that the motor-related temperature needs to reach.

[0280] The target temperature may be user-defined or determined based on actual execution conditions, and this application does not limit this.

[0281] During the actual execution process, after obtaining the ambient temperature, motor water temperature and motor body temperature, each temperature can be compared with its corresponding numerical value. When each temperature is based on its corresponding numerical value, the time required for the motor water temperature and motor body temperature at the current collection moment to reach the corresponding target temperature is calculated. Based on the required time and the time corresponding to the vehicle arriving at the target location, the target time for starting the motor active heating module is determined.

[0282] It will be appreciated that the amount of power consumed and the time required can be calculated by thermal management control software.

[0283] For example, in the on-the-way thermal management scenario, when the ambient temperature at the current collection moment is lower than 5 degrees, the motor water temperature is lower than 10 degrees, and the motor body temperature is lower than 70 degrees, the power consumed when the motor water temperature is heated to 20 degrees or the motor body temperature is heated to 80 degrees is calculated. At the same time, the time required to heat the motor water temperature to 20 degrees or the motor body temperature to 80 degrees is also calculated, so that the motor active heating module can be turned on in advance when approaching the destination.

[0284] According to the vehicle control method provided in the embodiment of the present application, through the correlation relationship between the working parameters in the in-transit thermal management scenario and the fourth target condition, when it is determined that the working parameters at the current collection moment meet the fourth target condition, the power and time required for the working parameters at the current collection moment to reach the target temperature are calculated, so as to determine the time suitable for turning on the motor active heating module, to ensure that when the vehicle arrives at the target location, the temperature related to the motor meets the target requirement, thereby improving the user experience and avoiding excessive energy waste in the environment, effectively saving energy.

[0285] In some embodiments, the method may further include:

[0286] Based on at least one of the actual state of charge of the battery, the battery temperature, and the motor temperature, a charging function heating strategy is output.

[0287] In this embodiment, during the actual implementation, it can be stated in the user manual of the vehicle that the user can save charging time and charging costs when choosing to charge the vehicle with the hot car.

[0288] During the actual implementation process, if the user chooses to charge the car with the heat on, the battery state of charge, battery temperature and motor temperature can be collected. When it is determined that the battery state of charge is lower than the target state of charge, the battery temperature is higher than the target battery temperature and the motor temperature is higher than the target motor temperature, the charging function heating strategy is output.

[0289] The charging function heating strategy can be used to estimate the cost and time saved by charging under the working parameters corresponding to the current collection time.

[0290] The charging function heating strategy can be output to the vehicle's instrument cluster.

[0291] According to the vehicle control method provided in the embodiment of the present application, by reminding the user to select a hot car for charging, and when it is determined that a hot car is selected for charging, the time and cost that can be saved by charging under the working parameters are output based on the actual charge state of the battery, the battery temperature and the motor temperature, thereby improving the economy of the vehicle and reducing the user's cost of use.

[0292] The vehicle control method provided in the embodiment of the present application can be executed by a vehicle control device. In the embodiment of the present application, the vehicle control device provided in the embodiment of the present application is described by taking the vehicle control method executed by the vehicle control device as an example.

[0293] An embodiment of the present application also provides a vehicle control device.

[0294] like Figure 7 As shown, the vehicle control device includes: a first processing module 710 and a second processing module 720 .

[0295] The first processing module 710 is used to obtain a user scenario corresponding to the vehicle; the user scenario includes at least one of a driving heating scenario, a charging scenario, and an on-the-way thermal management scenario;

[0296] The second processing module 720 is used to control the working state of at least one of the compressor heating module, the motor active heating module and the water heating module based on the user scenario.

[0297] According to the vehicle control device provided in the embodiment of the present application, by

[0298] In some embodiments, the second processing module 720 may also be used to:

[0299] When the user scenario is a driving heating scenario, the compressor heating module and the motor active heating module are controlled to be turned on, and based on the heating object, the working state of the water heating module is controlled; the heating object includes at least one of the cabin and the battery.

[0300] In some embodiments, the second processing module 720 may also be used to:

[0301] In the case where the heating object includes a cabin or a battery, obtaining at least one working parameter associated with the heating object;

[0302] When it is determined based on at least one operating parameter associated with the heating object that the first target condition is met, the water heating module is controlled to turn on.

[0303] In some embodiments, the second processing module 720 may also be used to:

[0304] When the heating objects include the cabin and the battery, determine the priority of the cabin and the battery;

[0305] Based on the priority level, determine the corresponding allocation ratio of cabin and battery;

[0306] Based on the distribution ratio, the water heating module is controlled to distribute heat to the cabin and the battery.

[0307] In some embodiments, the second processing module 720 may also be used to:

[0308] Control the motor circuit module to open;

[0309] Determining a target water temperature corresponding to the chiller based on at least one operating parameter corresponding to the vehicle;

[0310] Based on the target water temperature, the working state of the low-temperature heat dissipation module is controlled.

[0311] In some embodiments, the second processing module 720 may also be used to:

[0312] When the user scenario is a charging scenario and / or an in-transit thermal management scenario, the operating state of the motor active heating module is controlled based on at least one operating parameter corresponding to the vehicle.

[0313] In some embodiments, the second processing module 720 may also be used to:

[0314] When the user scenario is a charging scenario, a charging sub-scenario is determined; the charging sub-scenario includes a plug-in charging sub-scenario or a plug-in scheduled charging sub-scenario;

[0315] In the plug-in charging sub-scenario, and when it is determined based on at least one operating parameter that the second target condition is met, controlling the motor active heating module to turn on;

[0316] In the plug-in charging reservation sub-scenario, and when it is determined based on at least one operating parameter and the reservation information that the third target condition is met, the motor active heating module is controlled to turn on.
