[0062] The following will be combined with the accompanying drawings to clearly and thoroughly describe the technical solutions in this application. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0063] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features reflected. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0064] In order to illustrate the technical solution provided by the embodiments of the present application, some terms involved in the embodiments of the present application are introduced below.

[0065] Electric proportional valve: Also known as electric two-position three-way valve, it has two positions (two positions) and three channels (three-way). This valve can control the conversion of fluid flow direction and is usually used in hydraulic systems to achieve forward and reverse control or unloading functions of actuators. The design of the two-position three-way valve allows it to quickly switch the flow path of the medium without fine adjustment, which improves the convenience of operation and saves energy. Electric control means that the opening of the two-position three-way valve can be controlled by electrical signals.

[0066] Cooling circuit: A cooling circuit is a system used to circulate a cooling medium (usually liquid or gas) in various mechanical equipment to remove heat. In a car engine, the main function of the cooling circuit is to absorb the excess heat generated by the engine during operation and transfer this heat to the radiator, which dissipates the heat to the external environment through air flow, thereby keeping the engine within a suitable operating temperature range.

[0067] Vehicle components: Devices that provide corresponding functions for the vehicle. For example, engines, air conditioners, electric motors, etc. are all vehicle components.

[0068] Duty cycle: refers to the proportion of time occupied by the effective part of the signal (usually high level or low level) in a pulse cycle. In electronic control systems, duty cycle control (also known as pulse width modulation technology) controls the working state of electronic equipment by adjusting the duty cycle of the signal.

[0069] Air conditioning pressure: The pressure in the air conditioning system is usually divided into high pressure and low pressure, which are crucial for the normal operation of the air conditioner. High pressure usually refers to the pressure from the exhaust port of the compressor to the pressure before the throttle valve, while low pressure refers to the pressure from the throttle valve outlet to the air intake port of the compressor. In the embodiment of the present application, the air conditioning pressure refers to high pressure, that is, the pressure from the exhaust port of the compressor to the pressure before the throttle valve.

[0070] After introducing some terms involved in the embodiments of the present application, the implementation environment of the embodiments of the present application is introduced below.

That is, in the second cooling circuit, the coolant, under the action of the electric pump 103, passes through the radiator of the second cooling system 102, the target three-way valve 104, the loop radiator 106, the electric pump 103 and the connecting valve 105 in sequence, and finally returns to the radiator of the second cooling system 102.

[0073] In addition to sharing the electric pump 103, the first cooling circuit and the second cooling circuit also share the circuit radiator 106. The working principle of the circuit radiator 106 is based on heat conduction. The larger surface area of ​​the circuit radiator 106 can dissipate heat into the air, thereby achieving the purpose of heat dissipation.

[0074] Also, see Figure 2 From the perspective of control unit architecture, the implementation environment of the heat dissipation method for vehicle components provided in the embodiment of the present application includes a first electronic control unit 201, a second electronic control unit 202 and a cooling system control unit 203.

[0076] The first electronic control unit 201 is used to control the first vehicle component corresponding to the first cooling system. The first electronic control unit 201 can obtain the first component working parameter of the first vehicle component and determine the heat dissipation requirement of the first vehicle component.

[0077] The second electronic control unit 202 is used to control the second vehicle component corresponding to the second cooling system. The second electronic control unit 202 can obtain the second component operating parameters of the second vehicle component and determine the heat dissipation requirement of the second vehicle component.

[0080] After introducing the implementation environment of the embodiment of the present application, the application scenario of the technical solution provided by the embodiment of the present application is introduced below. The technical solution provided by the embodiment of the present application can be applied to various types of vehicles, for example, the technical solution provided by the embodiment of the present application can be applied to electric vehicles, hybrid vehicles, and fuel vehicles, and the embodiment of the present application does not limit this.

[0081] After adopting the technical solution provided in the embodiment of the present application, the cooling circuits corresponding to the two vehicle components can share an electric pump, and the electric pump and the target three-way valve can be controlled according to the working status of the two vehicle components, so that the two vehicle components can achieve better heat dissipation effect.

[0082] After introducing the implementation environment and application scenarios of the embodiments of the present application, the technical solutions provided by the embodiments of the present application are introduced below. Figure 1The technical solution provided by the embodiment of the present application is applied to a target vehicle, which includes a first cooling system 101 and a second cooling system 102. The first cooling system 101 is used to dissipate heat for a first vehicle component, and the second cooling system 102 is used to dissipate heat for a second vehicle component. The first cooling system 101 dissipates heat through a first cooling circuit, and the second cooling system 102 dissipates heat through a second cooling circuit. The first cooling circuit and the second cooling circuit are connected through a target three-way valve 104. The first cooling circuit and the second cooling circuit share an electric pump 103. The target three-way valve 104 is used to control the flow rate of coolant in the first cooling circuit and the second cooling circuit. See Figure 3 Taking the execution subject as a cooling system control unit as an example, the method includes the following steps.

[0083] 301. A cooling system control unit obtains a first component operating parameter of the first vehicle component and a second component operating parameter of the second vehicle component.

[0084] Wherein, the first vehicle component and the second vehicle component are both vehicle components that need to dissipate heat when working, for example, the first vehicle component and the second vehicle component are any two of vehicle components such as an engine, an electric motor, a power battery, and an air conditioner. The first component working parameter is used to indicate the working state of the first vehicle component, and the second component working parameter is used to indicate the working state of the second vehicle component. The first cooling system is a cooling system for dissipating heat for the first vehicle component. When the first vehicle component is an engine, the first cooling system is a water-cooled intercooler system. The second cooling system is a cooling system for dissipating heat for the second vehicle component. When the second vehicle component is an air conditioner, the second cooling system is a condensation system of the air conditioner. The first cooling system and the second cooling system each have a radiator, and the first cooling system dissipates heat through the first cooling circuit, which means that the radiator of the first cooling system dissipates heat through the first cooling circuit, and when the first cooling system is a water-cooled intercooler system, the radiator of the first cooling system is a water-cooled intercooler; accordingly, the second cooling system dissipates heat through the second cooling circuit, which means that the radiator of the second cooling system dissipates heat through the second cooling circuit, and when the second cooling system is a condensation system of the air conditioner, the radiator of the second cooling system is an air conditioner condenser. The first cooling circuit and the second cooling circuit share an electric pump, which means that the coolant in the first cooling circuit and the second cooling circuit flows under the drive of one electric pump. In the embodiment of the present application, the target three-way valve controls the flow of the coolant in the first cooling circuit and the second cooling circuit by adjusting the opening, and the target three-way valve is an electrically controlled three-way valve, so the opening of the target three-way valve can be controlled by an electrical signal.

[0085] 302. The cooling system control unit determines a target cooling mode based on the operating parameters of the first component and the second component, and adjusts the opening of the target three-way valve to a first target opening corresponding to the target cooling mode, wherein the target cooling mode is a cooling mode that matches the current operating states of the first vehicle component and the second vehicle component.

[0086] Among them, the opening of the target three-way valve and the control method of the electric pump are different in different heat dissipation modes, so that the flow direction and flow rate of the coolant are different, thereby finely controlling the heat dissipation of the first cooling system and the second cooling system.

[0087] 303. The cooling system control unit determines a first target heat dissipation requirement from a first heat dissipation requirement of the first vehicle component and a second heat dissipation requirement of the second vehicle component based on the target heat dissipation mode.

[0088] Among them, the heat dissipation demand refers to the demand for heat dissipation capacity. In the embodiment of the present application, the heat dissipation demand can control the speed of the electric pump, that is, the greater the heat dissipation demand, the greater the required heat dissipation capacity, and the coolant needs to flow at a faster speed, that is, the electric pump needs to provide a larger speed; correspondingly, the smaller the heat dissipation demand, the smaller the required heat dissipation capacity, and the coolant needs to flow at a slower speed, that is, the electric pump needs to provide a smaller speed. Different heat dissipation modes correspond to different ways of determining the first target heat dissipation demand.

[0089] 304. The cooling system control unit controls the electric pump to rotate at a first target speed corresponding to the first target heat dissipation requirement.

[0090] Through the technical solution provided in the embodiment of the present application, the first component working parameters of the first vehicle component and the second component working parameters of the second vehicle component are obtained. Using the first component working parameters and the second component working parameters, the target heat dissipation mode is determined and the opening of the target three-way valve is adjusted to the first target opening corresponding to the target heat dissipation mode, thereby realizing dynamic management of the flow direction of the coolant. Based on the target heat dissipation mode, the first target heat dissipation demand of the first vehicle component and the second heat dissipation demand of the second vehicle component is determined, and the electric pump is controlled to rotate at the first target speed corresponding to the first target heat dissipation demand, thereby realizing the heat dissipation control of the two cooling systems by using one electric pump, which is relatively low in cost.

[0091] It should be noted that the above steps 301-304 are a simple description of the heat dissipation method of the vehicle component provided in the embodiment of the present application. The heat dissipation method of the vehicle component provided in the embodiment of the present application will be described in more detail below with reference to some examples. Figure 1The technical solution provided by the embodiment of the present application is applied to a target vehicle, which includes a first cooling system 101 and a second cooling system 102. The first cooling system 101 is used to dissipate heat for a first vehicle component, and the second cooling system 102 is used to dissipate heat for a second vehicle component. The first cooling system 101 dissipates heat through a first cooling circuit, and the second cooling system 102 dissipates heat through a second cooling circuit. The first cooling circuit and the second cooling circuit are connected through a target three-way valve 104. The first cooling circuit and the second cooling circuit share an electric pump 103. The target three-way valve 104 is used to control the flow rate of coolant in the first cooling circuit and the second cooling circuit. See Figure 4 Taking the execution subject as a cooling system control unit as an example, the method includes the following steps.

[0092] 401. A cooling system control unit obtains a first component operating parameter of the first vehicle component and a second component operating parameter of the second vehicle component.

[0093] Among them, the first vehicle component and the second vehicle component are both vehicle components that need to dissipate heat when working. For example, the first vehicle component and the second vehicle component are any two of the vehicle components such as the engine, the motor, the power battery and the air conditioner. The specific selection and setting is made by the technician according to the actual situation, and the embodiment of the present application does not limit this. The first component working parameter is used to indicate the working state of the first vehicle component, and the second component working parameter is used to indicate the working state of the second vehicle component. The first cooling system is a cooling system for dissipating heat for the first vehicle component. When the first vehicle component is an engine, the first cooling system is a water-cooled intercooler system. The second cooling system is a cooling system for dissipating heat for the second vehicle component. When the second vehicle component is an air conditioner, the second cooling system is a condensing system of the air conditioner. The first cooling system and the second cooling system each have a radiator. The first cooling system dissipates heat through the first cooling circuit, which means that the radiator of the first cooling system dissipates heat through the first cooling circuit. When the first cooling system is a water-cooled intercooler system, the radiator of the first cooling system is a water-cooled intercooler. Correspondingly, the second cooling system dissipates heat through the second cooling circuit, which means that the radiator of the second cooling system dissipates heat through the second cooling circuit. When the second cooling system is a condensing system of an air conditioner, the radiator of the second cooling system is an air conditioner condenser. The first cooling circuit and the second cooling circuit share an electric pump, which means that the coolant in the first cooling circuit and the second cooling circuit flows under the drive of an electric pump. In an embodiment of the present application, the target three-way valve controls the flow of the coolant in the first cooling circuit and the second cooling circuit by adjusting the opening. The target three-way valve is an electrically controlled three-way valve, so the opening of the target three-way valve can be controlled by an electrical signal. In an embodiment of the present application, the electric valve, the target three-way valve, the pipeline corresponding to the first cooling circuit, and the pipeline corresponding to the second cooling circuit constitute a cooling system for dissipating heat for the first cooling system and the second cooling system.

[0094] In a possible implementation, the cooling system control unit obtains a first component operating parameter of the first vehicle component from the first electronic control unit, and obtains a second component operating parameter of the second vehicle component from the second electronic control unit.

[0095] The first electronic control unit is used to control the first vehicle component. When the first vehicle component is an engine, the first electronic control unit is an engine control unit; when the first vehicle component is a motor, the first electronic control unit is a motor control unit. The second electronic control unit is used to control the second vehicle component. When the second vehicle component is an air conditioner, the second electronic control unit is an air conditioner control unit; when the second vehicle component is a power battery, the second electronic control unit is a battery control unit. The first component operating parameter can indicate the operating state of the first vehicle component, that is, whether the first vehicle component is in or will be in a working state. Correspondingly, the second component operating parameter can indicate the operating state of the second vehicle component, that is, whether the second vehicle component is in or will be in a working state.

[0096] In this implementation, the operating parameters of the first component are obtained from the first electronic control unit, and the operating parameters of the second component are obtained from the second electronic control unit. The efficiency of obtaining the operating parameters is relatively high.

[0097] Optionally, after step 401, either steps 402-405 or steps 406 and 407 may be performed, which is not limited in the embodiment of the present application.

[0098] 402. The cooling system control unit determines a target heat dissipation mode based on the operating parameters of the first component and the second component, where the target heat dissipation mode is a heat dissipation mode that matches the current operating states of the first vehicle component and the second vehicle component.

[0099] Among them, the opening of the target three-way valve and the control method of the electric pump are different in different heat dissipation modes, so that the flow direction and flow rate of the coolant are different, thereby finely controlling the heat dissipation of the first cooling system and the second cooling system.

[0100] In a possible implementation, when the first component operating parameter indicates that the first vehicle component is in a working state, and the second component operating parameter indicates that the second vehicle component is not in a working state, the cooling system control unit determines a first heat dissipation mode as the target heat dissipation mode, and the first heat dissipation mode is a mode for dissipating heat for the first cooling system.

[0101] Among them, the first vehicle component is in working state, and the second vehicle component is not in working state, which means that the first vehicle component needs to dissipate heat, and the second vehicle component does not need to dissipate heat. Therefore, the first heat dissipation mode for dissipating heat for the first cooling system is determined as the target heat dissipation mode to achieve sufficient heat dissipation of the first vehicle component. In other words, if the first vehicle component is in working state, then the first cooling system is also in working state. In the first heat dissipation mode, the first cooling system can dissipate heat, thereby improving the effect of heat dissipation of the first vehicle component.

[0102] In this embodiment, when the first vehicle component is in operation and the second vehicle component is not in operation, the first heat dissipation mode for dissipating heat from the first cooling system is determined as the target heat dissipation mode. While fully dissipating the heat of the first vehicle component, the waste of heat dissipation capacity on the second vehicle component is reduced or avoided, and the heat dissipation capacity of the heat dissipation system is fully utilized.

[0103] For example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component, and obtains a second working state indication mark from the working parameters of the second component, wherein the first working state indication mark is used to indicate the working state of the first vehicle component, and the second working state indication mark is used to indicate the working state of the second vehicle component. When the first working state indication mark indicates that the first vehicle component is in a working state, and the second working state indication mark indicates that the second vehicle component is not in a working state, the cooling system control unit determines the first heat dissipation mode as the target heat dissipation mode.

[0104] Taking the first vehicle component as an engine and the second vehicle component as an onboard air conditioner as an example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component and obtains a second working state indication mark from the working parameters of the second component. When the first working state indication mark indicates that the engine is in a working state and the second working state indication mark indicates that the onboard air conditioner is not in a working state, the cooling system control unit determines the first heat dissipation mode as the target heat dissipation mode, and the first heat dissipation mode is also called a single engine mode, that is, a mode for cooling the engine alone.

[0105] Another implementation of the above step 402 is described below.

[0106] In a possible implementation, when the first component operating parameter indicates that the first vehicle component is not in a working state, and the second component operating parameter indicates that the second vehicle component is in a working state, the cooling system control unit determines the second heat dissipation mode as the target heat dissipation mode, and the second heat dissipation mode is a mode for dissipating heat to the second cooling system.

[0107] Among them, the first vehicle component is not in working state, and the second vehicle component is in working state, which means that the first vehicle component does not need to dissipate heat, and the second vehicle component needs to dissipate heat. Therefore, the second heat dissipation mode for dissipating heat for the first cooling system is determined as the target heat dissipation mode to achieve sufficient heat dissipation of the second vehicle component. In other words, if the second vehicle component is in working state, then the second cooling system is also in working state. In the second heat dissipation mode, the second cooling system can dissipate heat, thereby improving the effect of heat dissipation for the second vehicle component.

[0108] In this embodiment, when the first vehicle component is not in working condition and the second vehicle component is in working condition, the second heat dissipation mode for dissipating heat to the second cooling system is determined as the target heat dissipation mode. While achieving sufficient heat dissipation of the second vehicle component, the waste of heat dissipation capacity on the first vehicle component is reduced or avoided, and the heat dissipation capacity of the heat dissipation system is fully utilized.

[0109] For example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component, and obtains a second working state indication mark from the working parameters of the second component, wherein the first working state indication mark is used to indicate the working state of the first vehicle component, and the second working state indication mark is used to indicate the working state of the second vehicle component. When the first working state indication mark indicates that the first vehicle component is not in a working state, and the second working state indication mark indicates that the second vehicle component is in a working state, the cooling system control unit determines the second heat dissipation mode as the target heat dissipation mode.

[0110] Taking the first vehicle component as an engine and the second vehicle component as an onboard air conditioner as an example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component and obtains a second working state indication mark from the working parameters of the second component. When the first working state indication mark indicates that the engine is not in a working state and the second working state indication mark indicates that the onboard air conditioner is in a working state, the cooling system control unit determines the second heat dissipation mode as the target heat dissipation mode, and the second heat dissipation mode is also called a single air conditioning mode, that is, a mode for cooling the air conditioner alone.

[0111] Another implementation of the above step 402 is described below.

[0112] In one possible implementation, when the first component operating parameter indicates that the first vehicle component is in a working state, and the second component operating parameter indicates that the second vehicle component is in a working state, the cooling system control unit determines a third heat dissipation mode as the target heat dissipation mode, and the third heat dissipation mode is a mode for dissipating heat to the first cooling system and the second cooling system.

[0113] Among them, the first vehicle component is in a working state, and the second vehicle component is in a working state, which means that both the first vehicle component and the second vehicle component need to dissipate heat. Therefore, the third heat dissipation mode for dissipating heat for the first cooling system and the second cooling system is determined as the target heat dissipation mode to achieve sufficient heat dissipation for the first vehicle component and the second vehicle component.

[0114] In this embodiment, when the first vehicle component is in operation and the second vehicle component is in operation, the third heat dissipation mode for dissipating heat from the first cooling system is determined as the target heat dissipation mode to achieve sufficient heat dissipation for the first vehicle component and the second vehicle component.

[0115] For example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component, and obtains a second working state indication mark from the working parameters of the second component, wherein the first working state indication mark is used to indicate the working state of the first vehicle component, and the second working state indication mark is used to indicate the working state of the second vehicle component. When the first working state indication mark indicates that the first vehicle component is in a working state, and the second working state indication mark indicates that the second vehicle component is in a working state, the cooling system control unit determines the third heat dissipation mode as the target heat dissipation mode.

[0116] Taking the first vehicle component as an engine and the second vehicle component as an onboard air conditioner as an example, the cooling system control unit obtains a first working state indication mark from the working parameters of the first component and obtains a second working state indication mark from the working parameters of the second component. When the first working state indication mark indicates that the engine is in a working state and the second working state indication mark indicates that the onboard air conditioner is in a working state, the cooling system control unit determines the third heat dissipation mode as the target heat dissipation mode, and the third heat dissipation mode is also called a dual-circuit mode, that is, a mode for dissipating heat for both the engine and the air conditioner.

[0117] 403. The cooling control unit adjusts the opening of the target three-way valve to a first target opening corresponding to the target heat dissipation mode.

[0118] The corresponding relationship between different heat dissipation modes and the target three-way valve opening is set by technicians according to actual conditions, and this embodiment of the application does not limit this. Figure 1, the opening of the target three-way valve ranges from 0 to 100. When the opening of the target three-way valve is 0, it means that the first cooling circuit is fully opened and the second cooling circuit is fully closed, that is, the heat dissipation of the first cooling system is fully opened and the heat dissipation of the second cooling system is fully closed; correspondingly, when the opening of the target three-way valve is 100, it means that the first cooling circuit is fully closed and the second cooling circuit is fully opened, that is, the heat dissipation of the first cooling system is fully closed and the heat dissipation of the second cooling system is fully opened. In addition, when the opening of the target three-way valve is 50, it means that both the first cooling circuit and the second cooling circuit are opened and the opening degrees are the same. At this time, heat can be dissipated by the first cooling system and the second cooling system. In the embodiment of the present application, the first target opening is the first opening, the second opening or the third opening, which will be explained below respectively.

[0119] In a possible implementation, when the target heat dissipation mode is the first heat dissipation mode, the cooling system control unit adjusts the opening of the target three-way valve to a first opening corresponding to the first heat dissipation mode, and the first opening is an opening in which the coolant flow in the first cooling circuit is greater than that of the second cooling circuit.

[0120] There are two situations in which the coolant flow rate in the first cooling circuit is greater than that in the second cooling circuit. The first situation is that there is no coolant in the second cooling circuit, that is, the first cooling circuit is fully opened; the second situation is that there is coolant in the second cooling circuit, that is, the first cooling circuit is partially opened. In the first situation, the heat dissipation of the first cooling system can achieve the best effect; in the second situation, the flexibility of heat dissipation of the second cooling system can be retained, that is, once the second vehicle component has additional heat dissipation requirements, it can respond quickly.

[0121] In this embodiment, when the target heat dissipation mode is the first heat dissipation mode, the opening of the target three-way valve is adjusted to the first opening to control the coolant to flow more to the first cooling circuit, focusing on the heat dissipation of the first cooling system, thereby improving the heat dissipation effect on the first vehicle component.

[0122] For example, when the target heat dissipation mode is the first heat dissipation mode, the cooling system control unit sends a first control instruction to the target three-way valve, the first control instruction carries the first opening, and the first control instruction is used to instruct the target three-way valve to adjust the opening to the first opening. After receiving the first control instruction, the target three-way valve adjusts the opening to the first opening carried by the first control instruction.

[0123] Taking the opening range of the target three-way valve as 0 to 100, when the opening of the target three-way valve is 0, it indicates that the first cooling circuit is fully open; when the opening of the target three-way valve is 100, it indicates that the first cooling circuit is fully closed; when the opening of the target three-way valve is 50, it indicates that both the first cooling circuit and the second cooling circuit are opened and have the same opening degree. For example, the first opening is 0 or a value between 0 and 50 (excluding 50), such as 20, and the embodiments of the present application are not limited to this.

[0124] Another implementation of the above step 403 is described below.

[0125] In a possible implementation, when the target cooling mode is the second cooling mode, the cooling system control unit adjusts the opening of the target three-way valve to a second opening corresponding to the second cooling mode, and the second opening is an opening in which the coolant flow in the second cooling circuit is greater than that of the first cooling circuit.

[0126] There are two situations in which the coolant flow rate in the second cooling circuit is greater than that in the first cooling circuit. The first situation is that there is no coolant in the first cooling circuit, that is, the second cooling circuit is fully opened; the second situation is that there is coolant in the first cooling circuit, that is, the second cooling circuit is partially opened. In the first situation, the heat dissipation of the second cooling system can achieve the best effect; in the second situation, the flexibility of heat dissipation of the first cooling system can be retained, that is, once there is an additional heat dissipation demand for the first vehicle component, a quick response can be made.

[0127] In this embodiment, when the target heat dissipation mode is the second heat dissipation mode, the opening of the target three-way valve is adjusted to the second opening to control the coolant to flow more to the second cooling circuit, focusing on the heat dissipation of the second cooling system, thereby improving the heat dissipation effect on the second vehicle component.

[0128] For example, when the target heat dissipation mode is the second heat dissipation mode, the cooling system control unit sends a second control instruction to the target three-way valve, the second control instruction carries the second opening, and the second control instruction is used to instruct the target three-way valve to adjust the opening to the second opening. After receiving the second control instruction, the target three-way valve adjusts the opening to the second opening carried by the second control instruction.

[0129] Taking the opening range of the target three-way valve as 0 to 100, when the opening of the target three-way valve is 0, it indicates that the second cooling circuit is fully open; when the opening of the target three-way valve is 100, it indicates that the second cooling circuit is fully closed; when the opening of the target three-way valve is 50, it indicates that both the second cooling circuit and the first cooling circuit are opened and have the same opening degree. For example, the second opening is 100 or a value between 50 and 100 (excluding 100), such as 80, and the embodiments of the present application are not limited to this.

[0130] Another implementation of the above step 403 is described below.

[0131] In a possible implementation, when the target cooling mode is the third cooling mode, the cooling system control unit adjusts the opening of the target three-way valve to a third opening corresponding to the third cooling mode, and the third opening is the opening of the second cooling circuit at which the coolant flow in the first cooling circuit is equal to the coolant flow in the first cooling circuit.

[0132] In this embodiment, when the target heat dissipation mode is the third heat dissipation mode, the opening of the target three-way valve is adjusted to the third opening to control the coolant to flow evenly to the first cooling circuit and the second cooling circuit, thereby achieving heat dissipation of the first cooling system and the second cooling system, thereby achieving heat dissipation of the first vehicle component and the second vehicle component.

[0133] For example, when the target heat dissipation mode is the third heat dissipation mode, the cooling system control unit sends a third control instruction to the target three-way valve, the third control instruction carries the third opening, and the third control instruction is used to instruct the target three-way valve to adjust the opening to the third opening. After receiving the third control instruction, the target three-way valve adjusts the opening to the third opening carried by the third control instruction.

[0134] Taking the opening range of the target three-way valve as 0 to 100, when the opening of the target three-way valve is 0, it indicates that the first cooling circuit is fully open; when the opening of the target three-way valve is 100, it indicates that the first cooling circuit is fully closed; when the opening of the target three-way valve is 50, it indicates that both the first cooling circuit and the second cooling circuit are opened and have the same opening degree. For example, the third opening is 50.

[0135] 404. The cooling system control unit determines a first target heat dissipation requirement from a first heat dissipation requirement of the first vehicle component and a second heat dissipation requirement of the second vehicle component based on the target heat dissipation mode.

[0136] Among them, the heat dissipation demand refers to the demand for heat dissipation capacity. In the embodiment of the present application, the heat dissipation demand can control the rotation speed of the electric pump, that is, the greater the heat dissipation demand, the greater the required heat dissipation capacity, and the coolant needs to flow at a faster speed, that is, the electric pump needs to provide a larger rotation speed. Correspondingly, the smaller the heat dissipation demand, the smaller the required heat dissipation capacity, and the coolant needs to flow at a slower speed, that is, the electric pump needs to provide a smaller rotation speed. Different heat dissipation modes correspond to different ways of determining the first target heat dissipation demand. In some embodiments, the heat dissipation demand is positively correlated with the power of the electric pump.

[0137] In a possible implementation manner, when the target heat dissipation mode is the first heat dissipation mode, the cooling system control unit determines the first heat dissipation requirement as the first target heat dissipation requirement.

[0138] The first heat dissipation mode is a mode for dissipating heat for the first cooling circuit, so when determining the first heat dissipation requirement, the first heat dissipation requirement of the first vehicle component can be considered. In some embodiments, the first heat dissipation requirement is expressed in the form of a percentage. For example, when the first heat dissipation requirement is 50%, it means that the electric pump needs to work at 50% power.

[0139] In a possible implementation manner, when the target heat dissipation mode is the second heat dissipation mode, the cooling system control unit determines the second heat dissipation requirement as the first target heat dissipation requirement.

[0140] The second heat dissipation mode is a mode for dissipating heat for the second cooling circuit, so when determining the second heat dissipation requirement, the second heat dissipation requirement of the second vehicle component can be considered. In some embodiments, the second heat dissipation requirement is expressed in the form of a percentage. For example, when the second heat dissipation requirement is 80%, it means that the electric pump needs to work at 80% of the power.

[0141] In a possible implementation manner, when the target heat dissipation mode is the third heat dissipation mode, the cooling system control unit determines the larger heat dissipation requirement between the first heat dissipation requirement and the second heat dissipation requirement as the first target heat dissipation requirement.

[0142] Among them, determining the first target heat dissipation demand as the larger one of the first heat dissipation demand and the second heat dissipation demand can ensure that both the first heat dissipation demand and the second heat dissipation demand can be met, thereby achieving sufficient heat dissipation of the first cooling system and the second cooling system.

[0143] In order to explain the above implementation more clearly, the first heat dissipation requirement and the second heat dissipation requirement are explained below.

[0144] In a possible implementation, the first electronic control unit obtains a first component operating parameter of the first vehicle component, and the first electronic control unit determines a first heat dissipation requirement of the first vehicle component based on the first component operating parameter.

[0145] Among them, in addition to being used to indicate the working state of the first vehicle component, the first component working parameter can also be used to indicate the heat dissipation requirement of the first vehicle component. That is, in addition to including the first working state indication mark, the first component working parameter also includes a first heat dissipation requirement determination parameter, and the first heat dissipation requirement determination parameter is associated with the type of the first vehicle component.

[0146] For example, the first electronic control unit obtains a first component operating parameter of the first vehicle component, obtains a first heat dissipation requirement determination parameter from the first component operating parameter, and determines a first heat dissipation requirement of the first vehicle component based on the first heat dissipation requirement determination parameter.

[0147] Taking the first vehicle component as an engine as an example, the first cooling system is a water-cooled intercooler system of the engine, and the water-cooled intercooler system is used to cool the intake air temperature of the engine. Accordingly, the first heat dissipation demand determination parameter includes the target intake air temperature and the actual intake air temperature of the engine. The first electronic control unit determines the first heat dissipation demand of the first vehicle component based on the temperature difference between the target intake air temperature and the actual intake air temperature.

[0148] In a possible implementation, the second electronic control unit obtains a second component operating parameter of the second vehicle component, and the second electronic control unit determines a second heat dissipation requirement of the second vehicle component based on the second component operating parameter.

[0149] Among them, in addition to being used to indicate the working state of the second vehicle component, the second component operating parameters can also be used to indicate the heat dissipation requirements of the second vehicle component. That is, in addition to including the second working state indication mark, the second component operating parameters also include a second heat dissipation requirement determination parameter, and the second heat dissipation requirement determination parameter is associated with the type of the second vehicle component.

[0150] For example, the second electronic control unit obtains a second component operating parameter of the second vehicle component, obtains a second heat dissipation requirement determination parameter from the second component operating parameter, and determines a second heat dissipation requirement of the second vehicle component based on the second heat dissipation requirement determination parameter.

[0151] Taking the second vehicle component as an air conditioner as an example, the second cooling system is a condensing system of the air conditioner, and accordingly, the second heat dissipation requirement parameter includes air conditioner pressure and vehicle speed. The second electronic control unit determines the second heat dissipation requirement of the second vehicle component based on the air conditioner pressure and vehicle speed.

[0152] The air conditioning pressure is the pressure from the exhaust port of the compressor to the pressure before the throttle valve. An example of the relationship between the air conditioning pressure, the vehicle speed and the second heat dissipation demand is shown in the following Table 1.

[0153] Table 1

[0154]

[0155] Among them, up means going uphill or accelerating, and down means going downhill or decelerating.

[0156] 405. The cooling system control unit controls the electric pump to rotate at a first target speed corresponding to the first target heat dissipation requirement.

[0157] The corresponding relationship between the heat dissipation requirement and the speed of the electric pump is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. For example, if the first target heat dissipation requirement is a percentage within (0% to 100%), then the first target speed can be directly queried using the percentage of the first target heat dissipation requirement.

[0158] Optionally, after step 405, any one of the following two steps can be performed.

[0159] Step 1. When the target heat dissipation mode is the third heat dissipation mode, in response to the first fault flag, the cooling system control unit adjusts the opening of the target three-way valve to a second target opening, and the second target opening is that the coolant flow in the first cooling circuit is greater than the opening of the second cooling circuit. The first fault flag indicates that the first vehicle component has a temperature abnormality.

[0160] Among them, the third heat dissipation mode is a mode for dissipating heat to the first cooling system and the second cooling system. In the third heat dissipation mode, the opening of the target three-way valve is the third opening. When the target three-way valve is at the second target opening and the first opening, the coolant flow in the first cooling circuit is greater than that in the second cooling circuit. The first opening and the second target opening can be the same or different. The first opening and the second target opening are set by the technician according to the actual situation, and the embodiment of the present application does not limit this. Adjusting the opening of the target three-way valve from the third opening to the second target opening will increase the flow of coolant in the first cooling circuit. The abnormal temperature of the first vehicle component also means that the temperature of the first vehicle component is not within the normal range, which usually means that the temperature of the first vehicle component is too high. The opening of the target three-way valve is adjusted to the second target opening to improve the heat dissipation effect of the first vehicle component.

[0161] In the above embodiment, in the third heat dissipation mode, when a temperature abnormality occurs in the first vehicle component, the opening of the target three-way valve is adjusted to the second target opening to increase the flow rate of the coolant in the first cooling circuit, thereby improving the heat dissipation effect of the first vehicle component.

[0162] For example, when the target heat dissipation mode is the third heat dissipation mode, in response to the first fault flag, the cooling system control unit reacquires the first heat dissipation requirement of the first vehicle component and the second component operating parameter of the second vehicle component. When the reacquired first heat dissipation requirement and the reacquired second component operating parameter meet the first preset condition, the cooling system control unit adjusts the opening of the target three-way valve to the second target opening.

[0163] Among them, the first preset condition is set by technical personnel according to actual conditions, and the embodiment of the present application does not limit this.

[0164] For example, when the target heat dissipation mode is the third heat dissipation mode, in response to the first fault flag, the cooling system control unit reacquires the first heat dissipation demand of the first vehicle component and the second component operating parameter of the second vehicle component. When the reacquired first heat dissipation demand is greater than or equal to the heat dissipation demand threshold, and the second heat dissipation demand determination parameter in the second component operating parameter meets the first preset sub-condition, the cooling system control unit adjusts the opening of the target three-way valve to the second target opening.

[0165] Among them, the heat dissipation requirement threshold and the first preset sub-condition are set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0166] Taking the first vehicle component as an engine and the second vehicle component as an air conditioner as an example, when the target heat dissipation mode is the third heat dissipation mode, in response to the first fault flag, the cooling system control unit reacquires the first heat dissipation demand of the engine and the second component operating parameter of the air conditioner, and the second component operating parameter includes the air conditioning pressure of the air conditioner. When the reacquired first heat dissipation demand is greater than or equal to the heat dissipation demand threshold, and the air conditioning pressure is less than the air conditioning pressure threshold, the cooling system control unit adjusts the opening of the target three-way valve to the second target opening.

[0167] Among them, the air-conditioning pressure threshold is set by technicians according to actual conditions, such as being set to 2.1 MPa, etc., and the embodiments of the present application do not limit this.

[0168] Optionally, after step 1 above, at least one of the following two steps can be performed.

[0169] Step A: The cooling system control unit increases the first heat dissipation requirement that is reacquired to obtain a third heat dissipation requirement of the first vehicle component. The cooling system control unit determines a second target heat dissipation requirement based on the third heat dissipation requirement and the second heat dissipation requirement of the second vehicle component. The cooling system control unit controls the electric pump to rotate at a second target speed corresponding to the second target heat dissipation requirement.

[0170] Among them, increasing the re-acquired first heat dissipation demand is performed when the first fault flag is detected, that is, when the temperature abnormality occurs in the first vehicle component, the first heat dissipation demand of the first vehicle component is actively increased, thereby increasing the overall second target heat dissipation demand, which can control the electric pump to work at a higher power, and cooperate with the previous action of adjusting the opening of the target three-way valve to the second target opening, which can improve the heat dissipation effect of the first vehicle component.

[0171] For example, the cooling system control unit adds the first heat dissipation demand and the heat dissipation demand increment to obtain a third heat dissipation demand of the first vehicle component. The cooling system control unit determines the higher heat dissipation demand of the third heat dissipation demand and the second heat dissipation demand of the second vehicle component as the second target heat dissipation demand. The cooling system control unit controls the electric pump to rotate at a second target speed corresponding to the second target heat dissipation demand.

[0172] Step B: When the operating parameter of the second component of the second vehicle component meets the third preset condition and lasts for a duration greater than the first preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening.

[0173] Among them, the operating parameters of the second component of the second vehicle component meet the third preset condition and the duration is greater than the first preset duration, indicating that the heat dissipation demand of the second vehicle component has increased sharply, and it is necessary to increase the intensity of heat dissipation of the second cooling system. The third preset condition and the first preset duration are set by technical personnel according to actual conditions, such as setting the first preset duration to 60s, etc., which is not limited in the embodiments of the present application. Adjusting the opening of the target three-way valve from the second target opening to the third opening is to adjust the flow rate of the coolant in the first cooling circuit and the second cooling circuit from the first cooling circuit being greater than the second cooling circuit to the first cooling circuit being equal to the second cooling circuit, thereby achieving uniform heat dissipation of the first cooling system and the second cooling system.

[0174] For example, when the second heat dissipation demand determination parameter in the second component working parameter meets the third preset condition and lasts for a duration greater than the first preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening to improve the heat dissipation effect of the second cooling system.

[0175] Taking the first vehicle component as the engine and the second vehicle component as the air conditioner as an example, the working parameters of the second component include the air conditioning pressure of the air conditioner. When the air conditioning pressure is greater than or equal to the air conditioning pressure threshold and lasts for a duration greater than a first preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening.

[0176] Step 2. When the target heat dissipation mode is the third heat dissipation mode, in response to the second fault flag, the cooling system control unit adjusts the opening of the target three-way valve to a third target opening, where the coolant flow in the second cooling circuit is greater than the opening of the first cooling circuit, and the second fault flag indicates that a temperature abnormality occurs in the second vehicle component.

[0177] Among them, the third heat dissipation mode is a mode for dissipating heat to the first cooling system and the second cooling system. In the third heat dissipation mode, the opening of the target three-way valve is the third opening. When the target three-way valve is at the third target opening and the second opening, the coolant flow in the first cooling circuit is less than that in the second cooling circuit. The second opening and the third target opening can be the same or different. The second opening and the third target opening are set by the technician according to the actual situation, and the embodiment of the present application does not limit this. Adjusting the opening of the target three-way valve from the third opening to the third target opening will increase the flow of coolant in the second cooling circuit. The abnormal temperature of the second vehicle component also means that the temperature of the second vehicle component is not within the normal range, which usually means that the temperature of the second vehicle component is too high. The opening of the target three-way valve is adjusted to the third target opening to improve the heat dissipation effect of the second vehicle component.

[0178] In the above embodiment, in the third heat dissipation mode, when a temperature abnormality occurs in the second vehicle component, the opening of the target three-way valve is adjusted to a third target opening to increase the flow rate of coolant in the second cooling circuit, thereby improving the heat dissipation effect on the second vehicle component.

[0179] For example, when the target heat dissipation mode is the third heat dissipation mode, in response to the second fault flag, the cooling system control unit reacquires the second heat dissipation requirement of the second vehicle component and the first component operating parameter of the first vehicle component. When the reacquired second heat dissipation requirement and the reacquired first component operating parameter meet the second preset condition, the cooling system control unit adjusts the opening of the target three-way valve to the third target opening.

[0180] Among them, the second preset condition is set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0181] For example, when the target heat dissipation mode is the third heat dissipation mode, in response to the second fault flag, the cooling system control unit reacquires the second heat dissipation demand of the second vehicle component and the first component operating parameter of the first vehicle component. When the reacquired second heat dissipation demand is greater than or equal to the heat dissipation demand threshold, and the first heat dissipation demand determination parameter in the first component operating parameter meets the second preset sub-condition, the cooling system control unit adjusts the opening of the target three-way valve to the third target opening.

[0182] Among them, the heat dissipation requirement threshold and the second preset sub-condition are set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0183] Taking the first vehicle component as an engine and the second vehicle component as an air conditioner as an example, when the target heat dissipation mode is the third heat dissipation mode, in response to the second fault flag, the cooling system control unit reacquires the second heat dissipation demand of the air conditioner and the first component operating parameter of the engine, and the first component operating parameter includes the actual intake air temperature of the engine. When the reacquired second heat dissipation demand is greater than or equal to the heat dissipation demand threshold, and the actual intake air temperature is less than the intake air temperature threshold, the cooling system control unit adjusts the opening of the target three-way valve to the third target opening.

[0184] Among them, the intake air temperature threshold is set by technical personnel according to actual conditions, such as being set to 70°C, etc., and this embodiment of the present application does not limit this.

[0185] Optionally, after the above step 2, at least one of the following two steps can be performed.

[0186] Step C: The cooling system control unit increases the reacquired second heat dissipation requirement to obtain a fourth heat dissipation requirement of the second vehicle component. The cooling system control unit determines a third target heat dissipation requirement based on the fourth heat dissipation requirement and the first heat dissipation requirement of the first vehicle component. The cooling system control unit controls the electric pump to rotate at a third target speed corresponding to the third target heat dissipation requirement.

[0187] Among them, increasing the re-acquired second heat dissipation demand is performed when the second fault flag is detected, that is, when the temperature abnormality occurs in the second vehicle component, the second heat dissipation demand of the second vehicle component is actively increased, thereby increasing the overall third target heat dissipation demand, which can control the electric pump to work at a higher power, and cooperate with the previous action of adjusting the opening of the target three-way valve to the third target opening, which can improve the heat dissipation effect of the second vehicle component.

[0188] For example, the cooling system control unit adds the reacquired second heat dissipation demand to the heat dissipation demand increment to obtain a fourth heat dissipation demand of the second vehicle component. The cooling system control unit determines the higher heat dissipation demand between the fourth heat dissipation demand and the first heat dissipation demand of the first vehicle component as the third target heat dissipation demand. The cooling system control unit controls the electric pump to rotate at a third target speed corresponding to the third target heat dissipation demand.

[0189] Step D: When the operating parameter of the first component of the first vehicle component meets the fourth preset condition and lasts for a duration greater than the second preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the third target opening to the third opening.

[0190] Among them, the first component operating parameter of the first vehicle component meets the fourth preset condition and the duration is greater than the second preset duration, indicating that the heat dissipation demand of the first vehicle component has increased sharply, and it is necessary to increase the intensity of heat dissipation of the first cooling system. The fourth preset condition and the second preset duration are set by technical personnel according to actual conditions, such as setting the second preset duration to 90s, etc., which is not limited in the embodiment of the present application. Adjusting the opening of the target three-way valve from the second target opening to the third opening is to adjust the flow rate of the coolant in the first cooling circuit and the second cooling circuit from the second cooling circuit being greater than the first cooling circuit to the first cooling circuit being equal to the second cooling circuit, thereby achieving uniform heat dissipation of the first cooling system and the second cooling system.

[0191] For example, when the first heat dissipation demand determination parameter in the first component working parameter meets the fourth preset condition and lasts for a duration greater than the second preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening.

[0192] Taking the first vehicle component as an engine and the second vehicle component as an air conditioner as an example, the working parameters of the first component include the actual intake air temperature of the engine. When the actual intake air temperature is greater than or equal to the actual intake air temperature threshold and lasts for a duration greater than a second preset duration, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening to improve the heat dissipation effect of the first cooling system.

[0193] 406. When the first component operating parameter indicates that the first vehicle component is not in an operating state, and the second component operating parameter indicates that the second vehicle component is not in an operating state, the cooling system control unit adjusts the opening of the target three-way valve to a third opening, and the third opening is an opening at which the coolant flow in the first cooling circuit is equal to the second cooling circuit.

[0194] Among them, when both the first vehicle component and the second vehicle component are not working, the opening of the target three-way valve is adjusted to the third opening, so that the opening of the target three-way valve can be adjusted immediately when the first vehicle component or the second vehicle component starts to work subsequently.

[0195] 407. The cooling system control unit controls the electric pump to stop working.

[0196] Among them, both the first vehicle component and the second vehicle component are not working, so there is no need for heat dissipation. At this time, the electric pump is controlled to stop working to save energy.

[0197] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0198] Through the technical solution provided in the embodiment of the present application, the first component working parameters of the first vehicle component and the second component working parameters of the second vehicle component are obtained. Using the first component working parameters and the second component working parameters, the target heat dissipation mode is determined and the opening of the target three-way valve is adjusted to the first target opening corresponding to the target heat dissipation mode, thereby realizing dynamic management of the flow direction of the coolant. Based on the target heat dissipation mode, the first target heat dissipation demand of the first vehicle component and the second heat dissipation demand of the second vehicle component is determined, and the electric pump is controlled to rotate at the first target speed corresponding to the first target heat dissipation demand, thereby realizing the heat dissipation control of the two cooling systems by using one electric pump, which is relatively low in cost.

[0201] The opening determination module 502 is used to determine the target cooling mode based on the working parameters of the first component and the working parameters of the second component, and to adjust the opening of the target three-way valve to a first target opening corresponding to the target cooling mode, wherein the target cooling mode is a cooling mode that matches the current working states of the first vehicle component and the second vehicle component.

[0202] The heat dissipation requirement determination module 503 is used to determine a first target heat dissipation requirement from a first heat dissipation requirement of the first vehicle component and a second heat dissipation requirement of the second vehicle component based on the target heat dissipation mode.

[0203] The control module 504 is used to control the electric pump to rotate at a first target speed corresponding to the first target heat dissipation requirement.

[0204] In a possible implementation, the opening determination module 502 is used to determine the first heat dissipation mode as the target heat dissipation mode when the first component operating parameter indicates that the first vehicle component is in an operating state, and the second component operating parameter indicates that the second vehicle component is not in an operating state, and the first heat dissipation mode is a mode for dissipating heat to the first cooling system. When the first component operating parameter indicates that the first vehicle component is not in an operating state, and the second component operating parameter indicates that the second vehicle component is in an operating state, the second heat dissipation mode is determined as the target heat dissipation mode, and the second heat dissipation mode is a mode for dissipating heat to the second cooling system. When the first component operating parameter indicates that the first vehicle component is in an operating state, and the second component operating parameter indicates that the second vehicle component is in an operating state, the third heat dissipation mode is determined as the target heat dissipation mode, and the third heat dissipation mode is a mode for dissipating heat to the first cooling system and the second cooling system.

[0205] In a possible implementation, the first target opening is a first opening, a second opening or a third opening, and the opening determination module 502 is used to adjust the opening of the target three-way valve to a first opening corresponding to the first cooling mode when the target cooling mode is the first cooling mode, and the first opening is an opening at which the coolant flow in the first cooling circuit is greater than that of the second cooling circuit.

[0206] In a possible implementation, the control module 504 is further used to, when the target heat dissipation mode is the third heat dissipation mode, in response to the first fault flag, adjust the opening of the target three-way valve to a second target opening, the second target opening being the opening of the coolant flow in the first cooling circuit greater than the opening of the second cooling circuit, and the first fault flag indicating that the temperature of the first vehicle component is abnormal. When the target heat dissipation mode is the third heat dissipation mode, in response to the second fault flag, adjust the opening of the target three-way valve to a third target opening, the third target opening being the opening of the coolant flow in the second cooling circuit greater than the opening of the first cooling circuit, and the second fault flag indicating that the temperature of the second vehicle component is abnormal.

[0207] In a possible implementation, the control module 504 is further configured to, in response to the first fault flag, reacquire the first heat dissipation requirement of the first vehicle component and the second component operating parameter of the second vehicle component.

In response to the second fault flag, the second heat dissipation requirement of the second vehicle component and the first component operating parameter of the first vehicle component are reacquired. When the reacquired second heat dissipation requirement and the reacquired first component operating parameter meet the second preset condition, the opening of the target three-way valve is adjusted to the third target opening.
