[0035] To solve the problems of the prior art, embodiments of the present application provide a vehicle thermal management control method, device, system, electronic device, and vehicle. First, the vehicle thermal management control method provided by the embodiments of the present application will be introduced below.

[0036] Figure 1 The flowchart of the vehicle thermal management control method provided by an embodiment of the present application is shown. As Figure 1 shown, the vehicle thermal management control method provided by the embodiments of the present application is applied to a vehicle. The vehicle includes a first control valve and a heating source. The first control valve includes a first port and a plurality of second ports. The first port is communicated with the first flow passage of the vehicle, and each second port is communicated with the second flow passage of a to-be-heated component of the vehicle. The heating source is used to heat the working medium in the first flow passage. The method includes the following steps 101 - step 103, where:

[0037] Step 101, obtain a heating request, where the heating request includes the identifiers of M to-be-heated components and the heating parameters of the to-be-heated components, and M is a positive integer.

[0038] In this embodiment, a heating request is obtained. The heating request can be triggered by a user or the vehicle's battery system. For example, when the user turns on the heating mode of the vehicle's air conditioner, a heating request is triggered to heat the passenger compartment. At this time, the component to be heated is the heater core of the vehicle's air conditioner; or, when the ambient temperature where the vehicle is located is too low and it is detected that the battery temperature is lower than a preset value and the battery needs to be heated, the vehicle's battery system triggers a heating request to heat the battery. At this time, the component to be heated is the battery. In addition to the two single heating requests, there is also a dual heating request, that is, heating both the battery and the passenger compartment. At this time, the components to be heated include the battery and the heater core of the air conditioner.

[0039] Optionally, the vehicle includes an air conditioner controller, a battery controller, and an engine controller. The heating request can be sent from the air conditioner controller to the engine controller, or from the battery controller to the engine controller.

[0040] Among them, the heating request includes the identifiers of M components to be heated and the heating parameters of the components to be heated, where M is a positive integer.

[0041] Step 102, adjust the opening degrees of the multiple second ports of the first control valve according to the heating parameters of the M components to be heated.

[0042] See Figure 2 , the vehicle includes a first control valve and a heating source 201. The first control valve includes a first port 202 and multiple second ports 203. The first port 202 is connected to the first flow channel of the vehicle ( Figure 2 not shown in the figure), and each second port is connected to the second flow channel of a component to be heated in the vehicle ( Figure 2 not shown in the figure). As Figure 2 shown, one of the second ports 203 is connected to the second flow channel of the heater core 204 of the air conditioner, and another second port 203 is connected to the second flow channel of the battery 205; among them, the heating source 201 is used to heat the working medium in the first flow channel, and the working medium can be coolant.

[0043] In the above steps, adjusting the opening degrees of the multiple second ports of the first control valve according to the heating parameters of the M components to be heated and adjusting the opening degrees according to the actual heating requirements can meet the actual requirements.

[0044] Optionally, the first control valve can be controlled by the engine controller. The engine controller is used to adjust the opening degrees of the multiple second ports of the first control valve according to the heating parameters of the M components to be heated.

[0045] Step 103, during the process of heating the working medium in the first flow channel by using the heating source, control the operation of the water pump of the vehicle, so that the water pump controls the working medium to flow from the first flow channel through the first control valve to the second flow channel, and heat the component to be heated.

[0046] See Figure 2 , the vehicle further includes a water pump 206, and the water pump 206 is used to provide power for the flow of the working medium. During the process of heating the working medium in the first flow channel by using the heating source, control the operation of the water pump of the vehicle, so that the water pump controls the working medium to flow from the first flow channel through the first control valve to the second flow channel. Wherein, when the component to be heated is a battery, by controlling the operation of the water pump, the water pump controls the working medium to flow from the first flow channel through the second port corresponding to the battery of the first control valve to the second flow channel; when the component to be heated is a heater core, by controlling the operation of the water pump, the water pump controls the working medium to flow from the first flow channel through the second port corresponding to the heater core of the first control valve to the second flow channel; when the component to be heated includes a heater core and a battery, by controlling the operation of the water pump, the water pump controls the working medium to flow from the first flow channel through multiple second ports of the first control valve to the second flow channel.

[0047] Optionally, the water pump can be controlled by an engine controller, and the engine controller is used to control the operation of the water pump of the vehicle during the process of heating the working medium in the first flow channel by using the heating source.

[0048] In this embodiment, by obtaining a heating request, the heating request includes the identifiers of M components to be heated and the heating parameters of the components to be heated, where M is a positive integer; according to the heating parameters of the M components to be heated, adjust the opening degrees of multiple second ports of the first control valve; during the process of heating the working medium in the first flow channel by using the heating source, control the operation of the water pump of the vehicle, so that the water pump controls the working medium to flow from the first flow channel through the first control valve to the second flow channel, and heat the component to be heated. Through the above steps, the heated working medium can be conveyed to the corresponding component to be heated to provide heat for the component to be heated, and by adjusting the opening degree of the control valve, the flow rate of the working medium flowing to the component to be heated can be matched with the heating parameters of the component to be heated, avoiding heat waste or insufficient heat.

[0049] In an embodiment of the present application, step 103, according to the heating parameters of the M components to be heated, adjusting the opening degrees of the multiple second ports of the first control valve includes:

[0050] When only the heating parameter of one of the M parts to be heated includes a heating identifier, determine that the opening degree of the second port corresponding to the part to be heated is a first preset opening degree, and the opening degree of the second port corresponding to the other parts to be heated among the M parts to be heated is a second preset opening degree;

[0051] Adjust the opening degree of the second port corresponding to the part to be heated to the first preset opening degree, and adjust the opening degree of the second port corresponding to the other parts to be heated to the second preset opening degree, where the second preset opening degree is less than the first preset opening degree.

[0052] In this embodiment, when only the heating parameter of one of the M parts to be heated includes a heating identifier, for example, 1 is pre-set as the heating identifier, and the heating identifier is used to indicate heating of the part to be heated, indicating that only one part to be heated needs to be heated. Determine that the opening degree of the second port corresponding to this part to be heated is the first preset opening degree, while the other parts to be heated among the M parts to be heated do not need to be heated. Set the opening degree of the second port corresponding to the other parts to be heated among the M parts to be heated as the second preset opening degree, and the second preset opening degree is less than the first preset opening degree. For example, in order to avoid heat waste, the first preset opening degree can be set to fully open, and the second preset opening degree can be set to fully closed. All the flow only passes through the part to be heated with heating requirements, and only provides heat to the part to be heated with heating requirements, and does not provide heat to other parts to be heated.

[0053] In this embodiment, adjusting the valve opening degree according to the heating parameter can reasonably provide heat to the part to be heated with heating requirements.

[0054] In an embodiment of the present application, step 103, adjusting the opening degrees of the multiple second ports of the first control valve according to the heating parameters of the M parts to be heated includes:

[0055] When the heating parameters of at least two of the M parts to be heated include heating identifiers, determine the first working medium flow rate required to heat the at least two parts to be heated;

[0056] Adjust the opening degrees of the multiple second ports of the first control valve according to the first working medium flow rate.

[0057] In this embodiment, when the heating parameters of at least two of the M components to be heated include a heating identifier, the heating identifier is used to indicate heating of the components to be heated, indicating that at least two components to be heated need to be heated. Heating the components to be heated is achieved by heating the working medium and delivering the heated working medium to the second flow channel, thereby heating the components to be heated. In order to reasonably distribute heat to at least two components to be heated, the first working medium flow rate required to heat at least two components to be heated is calculated, and based on the first working medium flow rate, the opening degrees of multiple second ports of the first control valve are adjusted to provide heat for at least two components to be heated.

[0058] Optionally, the first control valve can be controlled by an engine controller, which is used to adjust the opening degrees of multiple second ports of the first control valve according to the first working medium flow rate.

[0059] By adjusting the opening degree of the control valve, the flow rate of the working medium flowing to the components to be heated can be effectively controlled, preventing waste or shortage of heat, and enabling the flow rate of the working medium flowing to the components to match the heating parameters of the components to be heated.

[0060] In an embodiment of the present application, the two components to be heated include: the battery of the vehicle and the air conditioner heater core;

[0061] Adjusting the opening degrees of multiple second ports of the first control valve according to the first working medium flow rate includes:

[0062] Obtaining a first correction coefficient corresponding to the first working medium flow rate in the first correspondence relationship, where the first correspondence relationship includes multiple working medium flow rates of the battery and the correction coefficient corresponding to each working medium flow rate;

[0063] Obtaining a second correction coefficient corresponding to the working speed of the first water pump in the second correspondence relationship, where the second correspondence relationship includes multiple working speeds and the correction coefficient corresponding to each working speed, and the first water pump is used to provide power for the working medium of the battery;

[0064] Obtaining a third correction coefficient corresponding to the temperature of the working medium in the first flow channel in the third correspondence relationship, where the third correspondence relationship includes the temperatures of multiple working media and the correction coefficient corresponding to each working medium temperature;

[0065] Multiplying the first correction coefficient, the second correction coefficient, and the third correction coefficient to obtain the first opening degree of the second port corresponding to the battery;

[0066] Adjust the opening degree of the second port corresponding to the battery to the first opening degree, and adjust the opening degree of the second port corresponding to the air-conditioning warm air core to the second opening degree, where the second opening degree is the opening degree obtained by subtracting the first opening degree from the third preset opening degree.

[0067] In this embodiment, a first correspondence, a second correspondence, and a third correspondence are preset. Among them, the first correspondence includes the flow rates of multiple working media of the battery and the correction coefficient corresponding to each working medium flow rate; the second correspondence includes multiple working speeds and the correction coefficient corresponding to each working speed; the third correspondence includes the temperatures of multiple working media and the correction coefficient corresponding to the temperature of each working medium.

[0068] In the above steps, obtain the first correction coefficient corresponding to the first working medium flow rate in the first correspondence; obtain the second correction coefficient corresponding to the working speed of the first water pump in the second correspondence. Refer to Figure 2 , where the first water pump 208 is used to provide power for the working medium of the battery; further, obtain the third correction coefficient corresponding to the temperature of the working medium in the first flow channel in the third correspondence.

[0069] Multiply the first correction coefficient, the second correction coefficient, and the third correction coefficient to obtain the first opening degree of the second port corresponding to the battery. The second port corresponding to the battery refers to the second port communicating with the second flow channel of the battery; adjust the opening degree of the second port corresponding to the battery to the first opening degree. According to the third preset opening degree minus the first opening degree, obtain the second opening degree, and adjust the opening degree of the second port corresponding to the warm air core to the second opening degree. The third preset opening degree is set according to the actual situation.

[0070] Alternatively, multiply the first correction coefficient, the second correction coefficient, and the third correction coefficient to obtain the opening degree ratio of the second port corresponding to the battery. Subtract the opening degree ratio from the preset ratio to obtain the opening degree ratio of the second port corresponding to the warm air core. Then, adjust the opening degree of the second port corresponding to the battery according to the opening degree ratio of the second port corresponding to the battery, and adjust the opening degree of the second port corresponding to the warm air core according to the opening degree ratio of the second port corresponding to the warm air core.

[0071] By calculating in the above manner, a more accurate working medium flow rate can be obtained, thereby effectively adjusting the opening degree of the control valve. Precise valve opening control can reduce energy consumption.

[0072] In an embodiment of the present application, the two components to be heated include: the battery of the vehicle and the air-conditioning warm air core; the heating parameters include: the target heating temperature, the lowest temperature of the battery cells, and the average temperature of the battery cells.

[0073] Determining the first working medium flow rate required to heat the at least two components to be heated includes:

[0074] Determining the flow rate corresponding to both the lowest temperature of the battery cell and the in-vehicle ambient temperature in the fourth corresponding relationship as the first flow rate, where the fourth corresponding relationship includes multiple lowest temperatures, multiple in-vehicle ambient temperatures, and the flow rate corresponding to each combination of the lowest temperature and the in-vehicle ambient temperature;

[0075] Multiplying the first flow rate, the fourth correction factor, the fifth correction factor, and the sixth correction factor to obtain the first working medium flow rate, where the fourth correction factor is determined by the temperature of the working medium in the first flow passage, the fifth correction factor is determined by the in-vehicle ambient temperature of the vehicle, and the sixth correction factor is determined by the target heating temperature and the outlet temperature of the heater of the vehicle.

[0076] In this embodiment, the two components to be heated include the vehicle's battery and the air-conditioning heater core, and the heating parameters include the target heating temperature, the lowest temperature of the battery cells, and the average temperature of the battery cells.

[0077] Preset the fourth corresponding relationship, which includes multiple lowest temperatures, multiple in-vehicle ambient temperatures, and the flow rate corresponding to each combination of the lowest temperature and the in-vehicle ambient temperature; determine the flow rate corresponding to both the lowest temperature of the battery cell and the in-vehicle ambient temperature in the fourth corresponding relationship as the first flow rate.

[0078] Preset the first mapping relationship, the second mapping relationship, and the third mapping relationship. Among them, the first mapping relationship includes multiple target working medium temperatures, multiple working medium temperature differences, and the correction factor corresponding to each combination of the target working medium temperature and the working medium temperature difference. Calculate the difference between the target working medium temperature corresponding to the heating request and the temperature of the working medium in the first flow passage to obtain the working medium temperature difference, and obtain the correction factor corresponding to both the target working medium temperature corresponding to the heating request and the working medium temperature difference in the first mapping relationship as the fourth correction factor;

[0079] Among them, the second mapping relationship includes multiple in-vehicle ambient temperatures and the correction factor corresponding to each in-vehicle ambient temperature. Obtain the correction factor corresponding to the in-vehicle ambient temperature of the vehicle in the second mapping relationship as the fifth correction factor.

[0080] Among them, the third mapping relationship includes multiple heating temperatures and multiple outlet temperatures, and the correction factor corresponding to each combination of the heating temperature and the outlet temperature. Obtain the correction factor corresponding to both the target heating temperature and the outlet temperature of the vehicle's heater in the third mapping relationship as the sixth correction factor, where the heat source includes a heater.

[0081] Multiply the first flow rate, the fourth correction coefficient, the fifth correction coefficient, and the sixth correction coefficient to obtain the first working medium flow rate.

[0082] In the case of dual heating, by calculating in the above manner, a more accurate working medium flow rate can be obtained, so as to effectively adjust the opening degree of the control valve and provide the respective required heat for the air-conditioning heater core and the battery.

[0083] In an embodiment of the present application, the heating source includes: the engine of the vehicle and the heater of the vehicle;

[0084] Before controlling the water pump of the vehicle to operate during the process of heating the working medium in the first flow passage by using the heating source, the method further includes:

[0085] When the temperature of the working medium in the first flow passage is less than or equal to a preset temperature, use the heater to heat the working medium in the first flow passage;

[0086] When the temperature of the working medium in the first flow passage is greater than the preset temperature, or when the opening degree of the engine exhaust gas recirculation valve is a fourth preset opening degree, use the engine to heat the working medium in the first flow passage.

[0087] The heating source includes the engine of the vehicle and the heater of the vehicle. Before using the heating source to heat the working medium in the first flow passage, it is necessary to determine which heating source to use for heating. If the temperature of the working medium in the first flow passage is less than or equal to the preset temperature, that is, the temperature of the working medium of the engine is less than or equal to the preset temperature, at this time, use the heater to heat the working medium in the first flow passage; if the temperature of the working medium in the first flow passage is greater than the preset temperature, that is, the temperature of the working medium of the engine is greater than the preset temperature, at this time, use the engine to heat the working medium in the first flow passage; or, when the exhaust gas recirculation (EGR) system is working and the opening degree of the engine exhaust gas recirculation valve is a fourth preset opening degree, at this time, use the engine to heat the working medium in the first flow passage.

[0088] Optionally, when the difference between the temperature of the working medium in the first flow passage and the outlet temperature of the heater is less than a threshold value, use the heater to heat the working medium in the first flow passage; or, when the difference between the temperature of the working medium in the first flow passage and the target water temperature of the heater is less than a threshold value, use the heater to heat the working medium in the first flow passage.

[0089] Optionally, when the temperature of the working medium in the first flow channel is greater than the calibration threshold, and the difference between the temperature of the working medium in the first flow channel and the outlet temperature of the heater is greater than the calibration threshold, the engine is used to heat the working medium in the first flow channel; or, when the difference between the temperature of the working medium in the first flow channel and the target water temperature of the heater is greater than the threshold, the engine is used to heat the working medium in the first flow channel.

[0090] Optionally, if the temperature of the working medium in the first flow channel is high enough, i.e., greater than the preset value, or the temperature of the working medium in the first flow channel is greater than the target water temperature of the heater, the engine is used to heat the working medium in the first flow channel.

[0091] Alternatively, if the temperature of the working medium in the first flow channel is not high enough, i.e., less than the preset value, and the heater is fault-free, after waiting for a preset duration, the heater is used to heat the working medium in the first flow channel. Alternatively, after waiting for a preset duration, if the difference between the outlet temperature of the heater and the target water temperature of the coolant heater is large, the engine is used to heat the working medium in the first flow channel. If the difference between the outlet temperature of the heater and the target water temperature of the coolant heater is small, the heater is switched to heat the working medium in the first flow channel.

[0092] When the temperature of the working medium in the first flow channel is less than or equal to the preset temperature, the engine is used to heat the working medium in the first flow channel, that is, the engine controller is used to control the engine to heat the working medium in the first flow channel.

[0093] When the temperature of the working medium in the first flow channel is greater than the preset temperature, or the opening of the engine exhaust gas recirculation valve is the fourth preset opening, the heater is used to heat the working medium in the first flow channel, that is, the engine controller is used to control the heater to heat the working medium in the first flow channel.

[0094] The engine controller determines the heater enabling conditions as follows: there is a heating request, the inlet temperature of the heater is lower than the preset protection temperature, the working medium water temperature of the engine cannot meet the heating demand, the energy management conditions are met, the flow rate of the working medium in the first flow channel is sufficient, the heater is fault-free, the water pump corresponding to the heater, i.e., the third water pump, and the water pump corresponding to the engine, i.e., the second water pump, are both fault-free, and the first control valve is fault-free. When all the above conditions are met, the engine controller sends an enabling request to the heater to start the heater to heat the working medium in the first flow channel.

[0095] A temperature sensor is preset to monitor the temperature of the working medium through the temperature sensor. It is mainly used to turn off the heater or reduce the power of the heater to prevent the heater from overheating. For example, when the temperature of the working medium exceeds 120 °C, the power of the heater is reduced; when the temperature of the working medium is lower than 115 °C, the power of the heater is restored; when the temperature of the working medium exceeds 125 °C, the heater is turned off, and when the temperature of the working medium is lower than 115 °C, the power of the heater is restored. The temperature can be set according to the actual situation and is not limited to the above values.

[0096] To prevent internal dry burning of the heater, the following requirements are preset: When starting, the water pump corresponding to the heater should start a few seconds earlier than the heater, such as 5 seconds, to ensure a stable water flow before starting the heater; the working medium needs to ensure at least a preset flow rate, such as 4 L / min, to start the heater. When the low working medium temperature system cannot meet the preset flow rate, the heater can also operate at a reduced load. Once the working medium temperature rises, a flow rate greater than the preset flow rate is required; when the heater is in the working state, it is necessary to ensure a stable water flow, and the water pump corresponding to the heater cannot stop suddenly; after the heater stops working, the water pump corresponding to the heater needs to run continuously for a period of time, such as more than 10 seconds, to avoid damaging the heater due to the remaining heat not being taken away by the working medium in time.

[0097] When there is a fault in the water pump corresponding to the heater, or, when there is a fault in the first control valve, or, when the heater reports a fault, or, when there is a fault in the water pump corresponding to the engine, the heater is controlled to stop working.

[0098] When using the heater to heat the working medium in the first flow channel, if the requested power of the heater is greater than the allowable power, such as the requested power is greater than 8 kw, and the temperature difference between the inlet and outlet of the heater is small, such as the temperature difference is less than 3 °C, then the engine is used to heat the working medium in the first flow channel; when using the engine to heat the working medium in the first flow channel, if the outlet temperature of the heater is lower than the target temperature of the heater, then the engine is used to heat the working medium in the first flow channel.

[0099] Using the engine or the heater as the heat source can meet the heating requirements of the component to be heated.

[0100] In an embodiment of the present application, the heating parameters include: the target heating temperature; the vehicle includes a second control valve, and the second control valve includes a third port and a fourth port; the first flow channel includes a first channel, a second channel, and a third channel.

[0105] Adjusting the working power of the heater to the second working power to heat the working medium in the first flow channel;

[0106] Controlling the third port to close and the fourth port to open so that the working medium flows from the third channel through the fourth port, the second channel, the heater, and the first control valve to the second flow channel to heat the component to be heated.

Specifically, the PID power is calculated according to the first value, the P-term coefficient, the I-term coefficient, and the D-term coefficient. Among them, the P-term coefficient is obtained by looking up a table according to the in-vehicle ambient temperature and the air volume of the air conditioner.

[0108] Calculating the first working power according to the in-vehicle ambient temperature, the air-conditioning evaporator temperature, the air volume of the air conditioner, the specific heat capacity, the power loss, and the battery heating power. The first working power is expressed as:

[0109] P = (T1 - T2) × A × S - P1 + P2 (1)

[0110] Where P is the first working power, T1 is the in-vehicle temperature of the vehicle, T2 is the air-conditioning evaporator temperature, A is the air volume of the air conditioner, S is the specific heat capacity, P1 is the power loss, and P2 is the battery heating power. The power loss and the battery heating power can be preset values.

[0126] It should be noted that when using the engine 2011 for heating, if the component to be heated is the air-conditioning heater core 204, then control the second port 203 communicating with the second flow channel of the air-conditioning heater core 204 to open, and control the second port 203 communicating with the second flow channel of the battery 205 to close; if the component to be heated is the battery 205, then control the second port 203 communicating with the second flow channel of the battery 205 to open, and control the second port 203 communicating with the second flow channel of the air-conditioning heater core 204 to close; if the components to be heated include the air-conditioning heater core 204 and the battery 205, then control the second port 203 communicating with the second flow channel of the air-conditioning heater core 204 to open, and control the second port 203 communicating with the second flow channel of the battery 205 to open.

[0127] When using the engine for heating, the working rotational speed can be accurately calculated in the above manner, and by controlling the opening or closing of the ports of the control valve, the heated working medium can flow to the component to be heated to provide heat for it.

[0128] In an embodiment of the present application, the heating source includes: the engine of the vehicle and the heater of the vehicle; the water pump includes: a second water pump configured for the engine and a third water pump configured for the heater, and both the second water pump and the third water pump are used to provide power for the flow of the working medium in the first flow channel;

[0129] During the process of using the heating source to heat the working medium in the first flow channel, controlling the water pump of the vehicle to operate includes:

[0130] During the process of heating the working medium in the first flow channel by using the engine, control the operation of the second water pump according to a second rotational speed, where the second rotational speed is determined by the first working medium flow rate;

[0131] and / or,

[0132] During the process of heating the working medium in the first flow channel by using the heater, control the operation of the third water pump according to a first duty ratio, where the first duty ratio is determined by the first working medium flow rate and the inlet water temperature of the heater.

[0133] See Figure 3 , the heating source includes the vehicle's engine 2011 and the vehicle's heater 2012, the vehicle's water pumps include the second water pump 2061 and the third water pump 2062, the second water pump 2061 is configured for the engine 2011, the third water pump 2062 is configured for the heater 2012, and both the second water pump and the third water pump are used to provide power for the flow of the working medium in the first flow channel.

Specifically, obtain the rotational speed corresponding to the first working medium flow rate in a fourth mapping relationship as the second rotational speed. The fourth mapping relationship includes multiple working medium flow rates and the rotational speed corresponding to each working medium flow rate. Control the operation of the second water pump according to the second rotational speed, that is, adjust the working rotational speed of the second water pump to the second rotational speed. The second water pump is used when heating the working medium by using the engine.

[0135] and / or;

[0136] During the process of heating the working medium in the first flow channel by using the heater, determine a first duty ratio according to the first working medium flow rate and the inlet water temperature of the heater. Specifically, obtain the duty ratio corresponding to both the first working medium flow rate and the inlet water temperature of the heater in a fifth mapping relationship as the first duty ratio. Among them, the fifth mapping relationship includes multiple working medium flow rates, multiple inlet water temperatures, and the duty ratio corresponding to each working medium flow rate and each inlet water temperature; control the operation of the third water pump according to the first duty ratio, and adjust the operation of the water pump through the duty ratio.

[0138] By calculating the duty ratio or rotational speed, the operation of the water pump can be reasonably controlled, improving the overall performance and reliability.

[0139] See Figure 3 , for the first water pump 208, a heat exchanger 207 is provided in the third heating passage, and the heat exchanger 207 is connected to the second flow passage of the battery 205; taking the heater as an example, when heating is performed using the heater 2012, if the component to be heated is the battery 205, the second port 203 communicating with the second flow passage of the battery 205 is controlled to open, so that the working medium flows from the third passage through the fourth port 210, the second passage, the heater 2012, and the second port 203 of the first control valve communicating with the second flow passage of the battery 205 to the second flow passage. When the working medium passes through the heat exchanger 207, heat exchange will occur, thereby heating the working medium of the battery in the third heating passage.

[0140] In an embodiment of the present application, the first working medium flow rate is determined according to one of the following:

[0141] When the heating parameter includes a target heating temperature and the component to be heated is the vehicle air-conditioning heater core, the flow rate corresponding to the target heating temperature and the temperature of the working medium of the engine in the seventh correspondence relationship is determined as the second flow rate, and, the second flow rate is added to the compensation flow rate to obtain the first working medium flow rate. The seventh correspondence relationship includes a plurality of target heating temperatures, a plurality of temperatures of the working medium, and the working medium flow rates respectively corresponding to each target heating temperature and each temperature of the working medium. The compensation flow rate is determined by the air volume of the vehicle blower and the vehicle interior ambient temperature;

[0142] Or,

[0143] When the heating parameters include the minimum temperature of the battery cells in the vehicle's battery and the average temperature of the battery cells, and the component to be heated is the battery, the flow rate corresponding to the minimum temperature of the battery cells in the battery and the average temperature of the multiple battery cells in the eighth corresponding relationship is determined as the third flow rate; and, the third flow rate, the seventh correction coefficient, and the eighth correction coefficient are multiplied to obtain the first working medium flow rate. The eighth corresponding relationship includes multiple minimum temperatures, multiple average temperatures, and the working medium flow rate corresponding to each minimum temperature and each average temperature. The seventh correction coefficient is determined by the temperature of the working medium, and the eighth correction coefficient is determined by the ambient temperature where the battery is located;

[0144] Or,

[0145] When the heating parameters include the target heating temperature, the minimum temperature of the battery cells in the battery, and the average temperature of the battery cells, and the components to be heated are the vehicle's air-conditioning heater core and the battery, the flow rate corresponding to the minimum temperature of the battery cells and the vehicle's interior ambient temperature in the fourth corresponding relationship is determined as the first flow rate. The fourth corresponding relationship includes multiple minimum temperatures, multiple interior ambient temperatures, and the flow rate corresponding to each minimum temperature and each interior ambient temperature; the first flow rate, the fourth correction coefficient, the fifth correction coefficient, and the sixth correction coefficient are multiplied to obtain the first working medium flow rate. The fourth correction coefficient is determined by the temperature of the working medium in the first flow passage, the fifth correction coefficient is determined by the vehicle's interior ambient temperature, and the sixth correction coefficient is determined by the target heating temperature and the outlet temperature of the vehicle's heater.

[0146] Among them, a seventh corresponding relationship is preset. The seventh corresponding relationship includes multiple target heating temperatures, multiple temperatures of the working medium, and the working medium flow rate corresponding to each target heating temperature and each temperature of the working medium. The second flow rate is determined according to the seventh corresponding relationship, so that the second flow rate is used to calculate the first working medium flow rate. Here, the first working medium flow rate is the working medium flow rate required to heat the air-conditioning heater core. Specifically, when the heating parameters include the target heating temperature and the component to be heated is the vehicle's air-conditioning heater core, the flow rate corresponding to the target heating temperature and the temperature of the working medium of the engine in the seventh corresponding relationship is determined as the second flow rate.

[0147] In addition, a sixth mapping relationship is preset. The sixth mapping relationship includes multiple blower air volumes, multiple interior ambient temperatures, and the compensation flow rate corresponding to each blower air volume and each interior ambient temperature; the compensation flow rate corresponding to the vehicle's blower air volume and the vehicle's interior ambient temperature in the sixth mapping relationship is obtained; the compensation flow rate and the second flow rate are added to obtain the first working medium flow rate.

[0148] Alternatively,

[0149] Preset an eighth correspondence relationship, which includes a plurality of minimum temperatures, a plurality of average temperatures, and the working medium flow rates respectively corresponding to each minimum temperature and each average temperature; determine a third flow rate according to the eighth correspondence relationship, so that the third flow rate calculates the first working medium flow rate according to this, where the first working medium flow rate is the working medium flow rate required to heat the battery. Specifically, when the heating parameters include the minimum temperature of the battery cells in the vehicle's battery and the average temperature of the battery cells, and the component to be heated is the battery, the flow rate corresponding to the minimum temperature of the battery cells in the battery and the average temperature of the multiple battery cells in the eighth correspondence relationship is determined as the third flow rate.

[0150] In addition, preset a seventh mapping relationship and an eighth mapping relationship. Among them, the seventh mapping relationship includes the temperatures of a plurality of working media and the correction coefficients respectively corresponding to the temperatures of each working medium, as the seventh correction coefficients; the eighth mapping relationship includes the ambient temperatures where a plurality of batteries are located and the correction coefficients respectively corresponding to each ambient temperature; obtain the correction coefficient corresponding to the current working medium temperature in the seventh mapping relationship as the seventh correction coefficient; and obtain the correction coefficient corresponding to the current ambient temperature where the battery is located in the eighth mapping relationship as the eighth correction coefficient. Further, multiply the third flow rate, the seventh correction coefficient, and the eighth correction coefficient to obtain the first working medium flow rate.

[0151] Alternatively,

[0152] When the heating parameters include the minimum temperature of the battery cells in the vehicle's battery and the average temperature of the battery cells, the component to be heated is the battery, and the battery is in a charging state, the flow rate corresponding to the minimum temperature of the battery cells in the battery and the average temperature of the multiple battery cells in the ninth correspondence relationship is determined as the fourth flow rate; and multiply the fourth flow rate, the ninth correction coefficient, and the tenth correction coefficient to obtain the first working medium flow rate. The ninth correspondence relationship includes a plurality of minimum temperatures, a plurality of average temperatures, and the working medium flow rates respectively corresponding to each minimum temperature and each average temperature. The ninth correction coefficient is determined by the temperature of the working medium, and the tenth correction coefficient is determined by the ambient temperature where the battery is located.

[0153] Alternatively, when the component to be heated is the battery and a preset function is activated, obtain a fourth correction coefficient and the requested flow rate when the preset function is activated, and multiply the requested flow rate by the fourth correction coefficient to obtain the first working medium flow rate. The activation of the preset function means the function of using the engine to heat the battery during a driving cycle.

[0154] Among them, a first mapping relationship is preset. The first mapping relationship includes the temperatures of multiple target working media, the temperature differences of multiple working media, and the correction coefficients respectively corresponding to the temperatures of each target working media and the temperature differences of the working media. Calculate the difference between the temperature of the target working media corresponding to the heating request and the temperature of the working media in the first flow channel to obtain the temperature difference of the working media. Obtain the correction coefficient corresponding to the temperature of the target working media and the temperature difference of the working media corresponding to the heating request in the first mapping relationship as the fourth correction coefficient.

[0155] Preset a fourth correspondence relationship. The fourth correspondence relationship includes multiple minimum temperatures, multiple vehicle interior environment temperatures, and the flow rates respectively corresponding to each minimum temperature and each vehicle interior environment temperature. Determine the flow rate corresponding to the minimum temperature of the battery cell and the vehicle interior environment temperature in the fourth correspondence relationship as the first flow rate. Thus, the first flow rate is used to calculate the first working medium flow rate, where the first working medium flow rate is the flow rate of the working medium required to heat the battery and the air conditioner heater core. Specifically, when the heating parameters include the target heating temperature, the minimum temperature of the battery cells, and the average temperature of the battery cells, and the component to be heated is the air conditioner heater core and the battery of the vehicle, multiply the first flow rate, the fourth correction coefficient, the fifth correction coefficient, and the sixth correction coefficient to obtain the first working medium flow rate.

[0156] In addition, a first mapping relationship, a second mapping relationship, and a third mapping relationship are preset. Among them, the first mapping relationship includes the temperatures of multiple target working media, the temperature differences of multiple working media, and the correction coefficients respectively corresponding to the temperatures of each target working media and the temperature differences of the working media. Calculate the difference between the temperature of the target working media corresponding to the heating request and the temperature of the working media in the first flow channel to obtain the temperature difference of the working media. Obtain the correction coefficient corresponding to the temperature of the target working media and the temperature difference of the working media corresponding to the heating request in the first mapping relationship as the fourth correction coefficient.

[0157] Among them, the second mapping relationship includes multiple vehicle interior environment temperatures and the correction coefficients respectively corresponding to each vehicle interior environment temperature. Obtain the correction coefficient corresponding to the vehicle interior environment temperature in the second mapping relationship as the fifth correction coefficient.

[0158] Among them, the third mapping relationship includes multiple heating temperatures and multiple outlet temperatures, and the correction coefficients respectively corresponding to each heating temperature and each outlet temperature. Obtain the correction coefficient corresponding to the target heating temperature and the outlet temperature of the vehicle heater in the third mapping relationship as the sixth correction coefficient.

[0159] Using correction coefficients in the calculation can quickly obtain a relatively reasonable estimation result, saving calculation time and effort and improving work efficiency.
