[0080] After introducing the implementation environment of the embodiments of the present application, the application scenarios of the technical solution provided by the embodiments of the present application are introduced. The technical solution provided by the embodiments of the present application can be applied in various vehicles, for example, the technical solution provided by the embodiments of the present application can be applied in electric vehicles, can also be applied in hybrid vehicles, and can also be applied in fuel vehicles, which are not limited by the embodiments of the present application.

[0081] After adopting the technical solution provided by the embodiments of the present application, the cooling circuits corresponding to two vehicle components can share one electric pump, and the control of the electric pump and the target three-way valve can be realized according to the working states 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 solution provided by the embodiments of the present application is introduced, which is described with reference to Figure 1The technical scheme provided by the embodiments of the present application is applied to a target vehicle, the target vehicle comprising a first cooling system 101 and a second cooling system 102, the first cooling system 101 being used for cooling a first vehicle component, the second cooling system 102 being used for cooling a second vehicle component, the first cooling system 101 cooling through a first cooling loop, the second cooling system 102 cooling through a second cooling loop, the first cooling loop and the second cooling loop being connected through a target three-way valve 104, the first cooling loop and the second cooling loop sharing an electric pump 103, the target three-way valve 104 being used for controlling the flow of cooling liquid in the first cooling loop and the second cooling loop, see Figure 3 The method comprises the following steps.

[0083] 301. The cooling system control unit acquires a first component working parameter of the first vehicle component and a second component working parameter of the second vehicle component.

[0084] The first vehicle component and the second vehicle component are both vehicle components that need to be cooled when working, for example, the first vehicle component and the second vehicle component are any two of an engine, an electric motor, a power battery, and an air conditioner. The first component working parameter is used to represent the working state of the first vehicle component, and the second component working parameter is used to represent the working state of the second vehicle component. The first cooling system is a cooling system used for cooling the first vehicle component. In the case that 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 used for cooling the second vehicle component. In the case that 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 cooling through the first cooling loop means that the radiator of the first cooling system cools through the first cooling loop. In the case that 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 cooling through the second cooling loop means that the radiator of the second cooling system cools through the second cooling loop. In the case that the second cooling system is a condensing system of the air conditioner, the radiator of the second cooling system is an air conditioner condenser. The first cooling loop and the second cooling loop sharing an electric pump means that the cooling liquid in the first cooling loop and the second cooling loop flows under the drive of one electric pump. In the embodiments of the present application, the target three-way valve controls the flow of cooling liquid in the first cooling loop and the second cooling loop by adjusting the opening degree. The target three-way valve is an electrically controlled three-way valve, and therefore the opening degree of the target three-way valve can be controlled through an electric signal.

[0085] 302、the cooling system control unit determines a target heat dissipation mode based on the first component working parameter and the second component working parameter, and adjusts the opening degree of the target three-way valve to a first target opening degree corresponding to the target heat dissipation mode, the target heat dissipation mode being a heat dissipation mode matching the current working states of the first vehicle component and the second vehicle component.

[0086] wherein the opening degree of the target three-way valve and the control mode 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 demand from the first heat dissipation demand of the first vehicle component and the second heat dissipation demand of the second vehicle component based on the target heat dissipation mode.

[0088] wherein the heat dissipation demand refers to the demand for heat dissipation capacity, in the embodiments of the present application, the heat dissipation demand can control the rotating speed of the electric pump, that is, the greater the heat dissipation demand, the greater the required heat dissipation capacity, so the coolant needs to flow at a faster speed, that is, the electric pump needs to provide a larger rotating speed; correspondingly, the smaller the heat dissipation demand, the smaller the required heat dissipation capacity, so the coolant needs to flow at a slower speed, that is, the electric pump needs to provide a smaller rotating 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 rotating speed corresponding to the first target heat dissipation demand.

[0090] Through the technical solutions provided in the embodiments of the present application, the first component working parameter of the first vehicle component and the second component working parameter of the second vehicle component are obtained. The first component working parameter and the second component working parameter are used to determine a target heat dissipation mode and adjust the opening degree of the target three-way valve to a first target opening degree 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, a first target heat dissipation demand is determined from the first heat dissipation demand of the first vehicle component and the second heat dissipation demand of the second vehicle component, and the electric pump is controlled to rotate at a first target rotating speed corresponding to the first target heat dissipation demand, thereby realizing heat dissipation control of two cooling systems by using one electric pump, which is low in cost.

[0091] It should be noted that the steps 301-304 above are a simple description of the heat dissipation method of the vehicle component provided in the embodiments of the present application, and the heat dissipation method of the vehicle component provided in the embodiments of the present application will be described in more detail below in conjunction with some examples, see Figure 1The technical scheme provided by the embodiments of the present application is applied to a target vehicle, the target vehicle comprising a first cooling system 101 and a second cooling system 102, the first cooling system 101 being used for cooling a first vehicle component, the second cooling system 102 being used for cooling a second vehicle component, the first cooling system 101 cooling through a first cooling loop, the second cooling system 102 cooling through a second cooling loop, the first cooling loop and the second cooling loop being connected through a target three-way valve 104, the first cooling loop and the second cooling loop sharing an electric pump 103, the target three-way valve 104 being used for controlling the flow of cooling liquid in the first cooling loop and the second cooling loop, see Figure 4 The method comprises the following steps.

[0092] 401、The cooling system control unit obtains a first component working parameter of the first vehicle component and a second component working parameter of the second vehicle component.

[0093] The first vehicle component and the second vehicle component are both vehicle components that need to be cooled during operation, for example, the first vehicle component and the second vehicle component are any two of an engine, an electric motor, a power battery, and an air conditioner, which are selected and set by the skilled person according to the actual situation, and the embodiments of the present application do not limit this. The first component operating parameter is used to represent the operating state of the first vehicle component, and the second component operating parameter is used to represent the operating state of the second vehicle component. The first cooling system is a cooling system for cooling the first vehicle component. In the case where 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 cooling the second vehicle component. In the case where the second vehicle component is an air conditioner, the second cooling system is a condenser system of the air conditioner. The first cooling system and the second cooling system each have a radiator. The first cooling system cools through a first cooling circuit, that is, the radiator of the first cooling system cools through the first cooling circuit. In the case where 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 cools through a second cooling circuit, that is, the radiator of the second cooling system cools through the second cooling circuit. In the case where the second cooling system is a condenser 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, that is, the cooling liquid in the first cooling circuit and the second cooling circuit flows under the drive of one electric pump. In the embodiments of the present application, the target three-way valve controls the flow of the cooling liquid in the first cooling circuit and the second cooling circuit by adjusting the opening degree. The target three-way valve is an electrically controlled three-way valve, and therefore the opening degree of the target three-way valve can be controlled by an electric signal. In the embodiments 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 form a cooling system for cooling the first cooling system and the second cooling system.

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

[0095] The first electronic control unit is configured 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 an electric motor, the first electronic control unit is an electric motor control unit. The second electronic control unit is configured 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 working parameter is indicative of a working state of the first vehicle component, i.e., whether the first vehicle component is in or will be in a working state. Correspondingly, the second component working parameter is indicative of a working state of the second vehicle component, i.e., whether the second vehicle component is in or will be in a working state.

[0096] In this embodiment, the first component working parameter is obtained from the first electronic control unit, and the second component working parameter is obtained from the second electronic control unit. The efficiency of obtaining the working parameters is high.

[0097] Optionally, after step 401, steps 402-405 or steps 406 and 407 can be performed, and the embodiments of the present application do not limit this.

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

[0099] In different heat dissipation modes, the opening degree of the target three-way valve and the control mode of the electric pump are different, 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 embodiment, when the first component working parameter indicates that the first vehicle component is in a working state, and the second component working parameter 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, the first heat dissipation mode being a mode of dissipating heat from the first cooling system.

[0101] The first vehicle component is in the working state, and the second vehicle component is not in the working state, which means that the first vehicle component needs to be cooled, and the second vehicle component does not need to be cooled. Therefore, the first cooling mode of cooling the first cooling system is determined as the target cooling mode to achieve sufficient cooling of the first vehicle component. In other words, the first vehicle component is in the working state, and the first cooling system is also in the working state. In the first cooling mode, the first cooling system can be cooled, thereby improving the cooling effect of the first vehicle component.

[0102] In this embodiment, in the case that the first vehicle component is in the working state and the second vehicle component is not in the working state, the first cooling mode of cooling the first cooling system is determined as the target cooling mode, which reduces or avoids wasting the cooling capacity to the second vehicle component in the case of achieving sufficient cooling of the first vehicle component, and the cooling capacity of the cooling system is fully utilized.

[0103] For example, the cooling system control unit obtains a first working state indication identifier from the first component working parameter and a second working state indication identifier from the second component working parameter. The first working state indication identifier is used to indicate the working state of the first vehicle component, and the second working state indication identifier is used to indicate the working state of the second vehicle component. In the case that the first working state indication identifier indicates that the first vehicle component is in the working state, and the second working state indication identifier indicates that the second vehicle component is not in the working state, the cooling system control unit determines the first cooling mode as the target cooling mode.

[0104] Taking the first vehicle component as an engine and the second vehicle component as a vehicle-mounted air conditioner as an example, the cooling system control unit obtains a first working state indication identifier from the first component working parameter and a second working state indication identifier from the second component working parameter. In the case that the first working state indication identifier indicates that the engine is in the working state, and the second working state indication identifier indicates that the vehicle-mounted air conditioner is not in the working state, the cooling system control unit determines the first cooling mode as the target cooling mode. The first cooling mode is also called a single-engine mode, that is, a mode of cooling the engine alone.

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

[0106] In a possible embodiment, in the case that the first component working parameter indicates that the first vehicle component is not in the working state, and the second component working parameter indicates that the second vehicle component is in the working state, the cooling system control unit determines the second cooling mode as the target cooling mode. The second cooling mode is a mode of cooling the second cooling system.

[0107] The first vehicle component is not in the working state, and the second vehicle component is in the working state, which means that the first vehicle component does not need to be cooled, and the second vehicle component needs to be cooled. Therefore, the second cooling mode of cooling the first cooling system is determined as the target cooling mode to achieve sufficient cooling of the second vehicle component. In other words, the second vehicle component is in the working state, and the second cooling system is also in the working state. In the second cooling mode, the second cooling system can be cooled, thereby improving the cooling effect of the second vehicle component.

[0108] In this embodiment, when the first vehicle component is not in the working state and the second vehicle component is in the working state, the second cooling mode of cooling the second cooling system is determined as the target cooling mode. In the case of achieving sufficient cooling of the second vehicle component, the cooling capacity is wasted to the first vehicle component, and the cooling capacity of the cooling system is fully utilized.

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

[0110] Taking the first vehicle component as the engine and the second vehicle component as the vehicle-mounted air conditioner as an example, the cooling system control unit obtains a first working state indication identifier from the first component working parameter and a second working state indication identifier from the second component working parameter. When the first working state indication identifier indicates that the engine is not in the working state, and the second working state indication identifier indicates that the vehicle-mounted air conditioner is in the working state, the cooling system control unit determines the second cooling mode as the target cooling mode. The second cooling mode is also called a single air conditioner mode, that is, a mode of cooling the air conditioner alone.

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

[0112] In one possible embodiment, when the first component working parameter indicates that the first vehicle component is in the working state, and the second component working parameter indicates that the second vehicle component is in the working state, the cooling system control unit determines a third cooling mode as the target cooling mode. The third cooling mode is a mode of cooling the first cooling system and the second cooling system.

[0113] The first vehicle component is in the working state, and the second vehicle component is in the working state, which means that the first vehicle component and the second vehicle component need to be cooled, and therefore, the third cooling mode in which the first cooling system and the second cooling system are cooled is determined as the target cooling mode to achieve sufficient cooling of the first vehicle component and the second vehicle component.

[0114] In this embodiment, in the case where the first vehicle component is in the working state and the second vehicle component is in the working state, the third cooling mode in which the first cooling system is cooled is determined as the target cooling mode to achieve sufficient cooling of the first vehicle component and the second vehicle component.

[0115] For example, the cooling system control unit obtains a first working state indication identifier from the first component working parameter and a second working state indication identifier from the second component working parameter, the first working state indication identifier indicating the working state of the first vehicle component, and the second working state indication identifier indicating the working state of the second vehicle component. In the case where the first working state indication identifier indicates that the first vehicle component is in the working state and the second working state indication identifier indicates that the second vehicle component is in the working state, the cooling system control unit determines the third cooling mode as the target cooling mode.

[0116] For example, the cooling system control unit obtains a first working state indication identifier from the first component working parameter and a second working state indication identifier from the second component working parameter, the first working state indication identifier indicating the working state of the first vehicle component, and the second working state indication identifier indicating the working state of the second vehicle component. In the case where the first working state indication identifier indicates that the first vehicle component is in the working state and the second working state indication identifier indicates that the second vehicle component is in the working state, the cooling system control unit determines the third cooling mode as the target cooling mode.

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

[0118] The correspondence between different cooling modes and the opening of the target three-way valve is set by the technician according to the actual situation, and the embodiments of the present application do not limit this. See Figure 1, the target three-way valve has an opening degree ranging from 0 to 100, and when the opening degree of the target three-way valve is 0, it indicates that the first cooling circuit is fully opened and the second cooling circuit is fully closed, i.e., 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 degree of the target three-way valve is 100, it indicates that the first cooling circuit is fully closed and the second cooling circuit is fully opened, i.e., 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 degree of the target three-way valve is 50, it indicates that the first cooling circuit and the second cooling circuit are both opened and have the same opening degree, and at this time, the first cooling system and the second cooling system can be cooled. In the embodiments of the present application, the first target opening degree is the first opening degree, the second opening degree or the third opening degree, which will be described below.

[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 degree of the target three-way valve to the first opening degree corresponding to the first heat dissipation mode, and the first opening degree is that the cooling liquid flow in the first cooling circuit is greater than that in the second cooling circuit.

[0120] There are two cases for the first cooling circuit having a greater cooling liquid flow than the second cooling circuit. The first case is that there is no cooling liquid in the second cooling circuit, i.e., the first cooling circuit is fully opened; the second case is that there is cooling liquid in the second cooling circuit, i.e., the first cooling circuit is partially opened. In the first case, the heat dissipation of the first cooling system can achieve the best effect; in the second case, the flexibility of the heat dissipation of the second cooling system can be reserved, i.e., once there is an additional heat dissipation demand of the second vehicle component, a quick response can be made.

[0121] In this implementation, when the target heat dissipation mode is the first heat dissipation mode, the opening degree of the target three-way valve is adjusted to the first opening degree to control the cooling liquid to flow more to the first cooling circuit, and focus on the heat dissipation of the first cooling system, thereby improving the heat dissipation effect of 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, and the first control instruction carries the first opening degree, and the first control instruction is used to instruct the target three-way valve to adjust the opening degree to the first opening degree. After receiving the first control instruction, the target three-way valve adjusts the opening degree to the first opening degree carried by the first control instruction.

[0123] The range of the opening degree of the target three-way valve is 0-100, where the opening degree of the target three-way valve is 0, indicating that the first cooling circuit is fully opened; the opening degree of the target three-way valve is 100, indicating that the first cooling circuit is fully closed; and the opening degree of the target three-way valve is 50, indicating that the first cooling circuit and the second cooling circuit are both opened and have the same opening degree. For example, the first opening degree is 0 or a value in the range of 0-50 (not including 50), such as 20, which is not limited in the embodiments of the application.

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

[0125] In a possible embodiment, when the target heat dissipation mode is the second heat dissipation mode, the cooling system control unit adjusts the opening degree of the target three-way valve to a second opening degree corresponding to the second heat dissipation mode, where the cooling liquid flow in the second cooling circuit is greater than the opening degree of the first cooling circuit.

[0126] There are two cases where the cooling liquid flow in the second cooling circuit is greater than the first cooling circuit. The first case is that there is no cooling liquid in the first cooling circuit, that is, the second cooling circuit is fully opened. The second case is that there is cooling liquid in the first cooling circuit, that is, the second cooling circuit is partially opened. In the first case, the heat dissipation of the second cooling system can achieve the best effect. In the second case, the flexibility of heat dissipation of the first cooling system can be retained, that is, once there is an additional heat dissipation requirement of 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 degree of the target three-way valve is adjusted to the second opening degree to control the cooling liquid to flow more to the second cooling circuit, focus on the heat dissipation of the second cooling system, thereby improving the heat dissipation effect of 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, where the second control instruction carries the second opening degree, and the second control instruction is used to instruct the target three-way valve to adjust the opening degree to the second opening degree. After receiving the second control instruction, the target three-way valve adjusts the opening degree to the second opening degree carried by the second control instruction.

[0129] For example, when the target cooling mode is the third cooling mode, the opening degree of the target three-way valve is adjusted to a third opening degree corresponding to the third cooling mode, and the third opening degree is equal to the opening degree of the second cooling circuit.

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

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

[0132] In this implementation, when the target cooling mode is the third cooling mode, the opening degree of the target three-way valve is adjusted to the third opening degree to control the cooling liquid to flow uniformly to the first cooling circuit and the second cooling circuit, so as to achieve the heat dissipation of the first cooling system and the second cooling system, thereby achieving the heat dissipation of the first vehicle component and the second vehicle component.

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

[0134] For example, when the target cooling mode is the third cooling mode, the opening degree of the target three-way valve is adjusted to a third opening degree corresponding to the third cooling mode, and the third opening degree is equal to the opening degree of the second cooling circuit.

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

[0136] The heat dissipation requirement refers to a requirement for heat dissipation capacity. In the embodiments of the present application, the heat dissipation requirement can control the rotating speed of the electric pump. That is, the greater the heat dissipation requirement, the greater the required heat dissipation capacity, and then the cooling liquid needs to flow at a faster speed, that is, the electric pump needs to provide a greater rotating speed. Correspondingly, the smaller the heat dissipation requirement, the smaller the required heat dissipation capacity, and then the cooling liquid needs to flow at a slower speed, that is, the electric pump needs to provide a smaller rotating speed. Different heat dissipation modes correspond to different ways of determining the first target heat dissipation requirement. In some embodiments, the heat dissipation requirement is positively correlated with the power of the electric pump.

[0137] In a possible implementation, 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 of dissipating heat for the first cooling loop, and therefore, when determining the first heat dissipation requirement, the first heat dissipation requirement of the first vehicle component is 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, 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 of dissipating heat for the second cooling loop, and therefore, when determining the second heat dissipation requirement, the second heat dissipation requirement of the second vehicle component is 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% power.

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

[0142] Determining the first target heat dissipation requirement as the greater one between the first heat dissipation requirement and the second heat dissipation requirement can ensure that both the first heat dissipation requirement and the second heat dissipation requirement can be met, thereby achieving sufficient heat dissipation for the first cooling system and the second cooling system.

[0143] In order to more clearly illustrate the above embodiments, the ways of determining the first heat dissipation requirement and the second heat dissipation requirement are described below.

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

[0145] The first component working parameter can be used to represent the heat dissipation requirement of the first vehicle component in addition to representing the working state of the first vehicle component, i.e., the first component working parameter comprises a first heat dissipation requirement determining parameter in addition to a first working state indicating identifier, and the first heat dissipation requirement determining parameter is associated with the type of the first vehicle component.

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

[0147] For example, the first vehicle component is an engine, and the first cooling system is a water-cooled intercooler system of the engine, which is used to cool the intake air temperature of the engine. Accordingly, the first heat dissipation requirement determining parameter comprises a target intake air temperature and an actual intake air temperature of the engine. The first electronic control unit determines the first heat dissipation requirement 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 working parameter of the second vehicle component. The second electronic control unit determines a second heat dissipation requirement of the second vehicle component based on the second component working parameter.

[0149] The second component working parameter can be used to represent the heat dissipation requirement of the second vehicle component in addition to representing the working state of the second vehicle component, i.e., the second component working parameter comprises a second heat dissipation requirement determining parameter in addition to a second working state indicating identifier, and the second heat dissipation requirement determining parameter is associated with the type of the second vehicle component.

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

[0151] For example, the second vehicle component is an air conditioner, and the second cooling system is a condenser system of the air conditioner. Accordingly, the second heat dissipation requirement parameter comprises an air conditioner pressure and a 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 the vehicle speed.

[0152] Wherein, the air conditioning pressure is the pressure from the exhaust port of the compressor to the front of the throttle valve, one example of the relationship between the air conditioning pressure, the vehicle speed and the second heat dissipation requirement is shown in Table 1 below.

[0153] Table 1

[0154]

[0155] Wherein, up indicates uphill or acceleration, and down indicates downhill or deceleration.

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

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

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

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

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

[0161] In the third cooling mode, in the case that the temperature of the first vehicle component is abnormal, the opening degree of the target three-way valve is adjusted to the second target opening degree to increase the flow of the coolant in the first cooling circuit, so as to improve the cooling effect of the first vehicle component.

[0162] For example, in the case that the target cooling mode is the third cooling mode, in response to the first fault flag, the cooling system control unit reacquires the first cooling demand of the first vehicle component and the second component working parameter of the second vehicle component. In the case that the reacquired first cooling demand and the reacquired second component working parameter meet the first preset condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the second target opening degree.

[0163] The first preset condition is set by the technician according to the actual situation, and the embodiments of the present application are not limited thereto.

[0164] For example, in the case that the target cooling mode is the third cooling mode, in response to the first fault flag, the cooling system control unit reacquires the first cooling demand of the first vehicle component and the second component working parameter of the second vehicle component. In the case that the reacquired first cooling demand is greater than or equal to the cooling demand threshold, and the second cooling demand determining parameter in the second component working parameter meets the first preset sub-condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the second target opening degree.

[0165] The cooling demand threshold and the first preset sub-condition are set by the technician according to the actual situation, and the embodiments of the present application are not limited thereto.

[0166] For example, in the case that the target cooling mode is the third cooling mode, in response to the first fault flag, the cooling system control unit reacquires the first cooling demand of the first vehicle component and the second component working parameter of the second vehicle component. In the case that the reacquired first cooling demand is greater than or equal to the cooling demand threshold, and the second cooling demand determining parameter in the second component working parameter meets the first preset sub-condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the second target opening degree.

[0167] The air conditioner pressure threshold is set by the technician according to the actual situation, such as 2.1 MPa, and the embodiments of the present application are not limited thereto.

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

[0169] The cooling system control unit increases the first heat dissipation requirement 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 rotating speed corresponding to the second target heat dissipation requirement.

[0170] The first heat dissipation requirement reacquired is increased in a case where the first fault flag bit is detected, that is, in a case where the temperature of the first vehicle component is abnormal, the first heat dissipation requirement of the first vehicle component is actively increased, so as to increase the second target heat dissipation requirement, so that the electric pump can work at a greater power, and the opening of the target three-way valve is adjusted to the second target opening, so as to improve the heat dissipation effect of the first vehicle component.

[0171] For example, the cooling system control unit adds the first heat dissipation requirement reacquired and the heat dissipation requirement increment to obtain a third heat dissipation requirement of the first vehicle component. The cooling system control unit determines the second target heat dissipation requirement as the higher heat dissipation requirement between 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 rotating speed corresponding to the second target heat dissipation requirement.

[0172] In a case where the second component working parameter of the second vehicle component meets a third preset condition and lasts for a time longer than a first preset time, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening.

[0173] The second component working parameter of the second vehicle component meeting the third preset condition and lasting for a time longer than the first preset time indicates that the heat dissipation requirement of the second vehicle component increases rapidly, and the intensity of heat dissipation of the second cooling system needs to be increased. The third preset condition and the first preset time are set by technicians according to actual conditions, for example, the first preset time is set to 60s, and the present application is not limited in this regard. Adjusting the opening of the target three-way valve from the second target opening to the third opening means adjusting the flow of the coolant in the first cooling loop and the second cooling loop from the first cooling loop being greater than the second cooling loop to the first cooling loop being equal to the second cooling loop, so as to realize uniform heat dissipation of the first cooling system and the second cooling system.

[0174] For example, in a case where the second heat dissipation requirement determination parameter in the second component working parameter meets the third preset condition and lasts for a time longer than the first preset time, the cooling system control unit adjusts the opening of the target three-way valve from the second target opening to the third opening, so as to improve the heat dissipation effect of the second cooling system.

[0175] For example, the first vehicle component is an engine, and the second vehicle component is an air conditioner. The second component working parameter includes an air conditioner pressure of the air conditioner. In a case where the air conditioner pressure is greater than or equal to an air conditioner pressure threshold and the duration is greater than a first preset duration, the cooling system control unit adjusts the opening degree of the target three-way valve from the second target opening degree to the third opening degree.

[0176] In a case where the target cooling mode is a third cooling mode, the cooling system control unit adjusts the opening degree of the target three-way valve to a third target opening degree in response to a second fault flag. The third target opening degree is an opening degree at which the cooling liquid flow in the second cooling loop is greater than that in the first cooling loop. The second fault flag indicates that the second vehicle component has a temperature anomaly.

[0177] The third cooling mode is a cooling mode in which the first cooling system and the second cooling system are cooled. In the third cooling mode, the opening degree of the target three-way valve is the third opening degree. In the third target opening degree and the second opening degree, the cooling liquid flow in the first cooling loop is less than that in the second cooling loop. The second opening degree and the third target opening degree can be the same or different. The second opening degree and the third target opening degree are set by the technician according to the actual situation, and the embodiments of the present application do not limit this. Adjusting the opening degree of the target three-way valve from the third opening degree to the third target opening degree increases the flow of the cooling liquid in the second cooling loop. The temperature anomaly of the second vehicle component indicates that the temperature of the second vehicle component is not within the normal range. Generally, it means that the temperature of the second vehicle component is too high. Adjusting the opening degree of the target three-way valve to the third target opening degree improves the cooling effect of the second vehicle component.

[0178] In the above embodiment, in the third cooling mode, the opening degree of the target three-way valve is adjusted to the third target opening degree in a case where the second vehicle component has a temperature anomaly, so as to increase the flow of the cooling liquid in the second cooling loop, thereby improving the cooling effect of the second vehicle component.

[0179] For example, in a case where the target cooling mode is the third cooling mode, the cooling system control unit reacquires the second cooling demand of the second vehicle component and the first component working parameter of the first vehicle component in response to the second fault flag. In a case where the reacquired second cooling demand and the reacquired first component working parameter meet a second preset condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the third target opening degree.

[0180] The second preset condition is set by the technician according to the actual situation, and the embodiments of the present application do not limit this.

[0181] For example, in a case where 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. In a case where the reacquired second heat dissipation requirement is greater than or equal to the heat dissipation requirement threshold value and the first heat dissipation requirement determination parameter in the first component operating parameter meets the second preset sub-condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the third target opening degree.

[0182] The heat dissipation requirement threshold value and the second preset sub-condition are set by a technician according to actual conditions, and embodiments of the present application do not limit this.

[0183] For example, in a case where 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. In a case where the reacquired second heat dissipation requirement is greater than or equal to the heat dissipation requirement threshold value and the first heat dissipation requirement determination parameter in the first component operating parameter meets the second preset sub-condition, the cooling system control unit adjusts the opening degree of the target three-way valve to the third target opening degree.

[0184] The intake air temperature threshold value is set by a technician according to actual conditions, for example, set to 70°C, and embodiments of the present application do 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 rotating speed corresponding to the third target heat dissipation requirement.

[0187] The increase in the reacquired second heat dissipation requirement is performed in a case where the second fault flag is detected, that is, in a case where the temperature of the second vehicle component is abnormal, the second heat dissipation requirement of the second vehicle component is actively increased, thereby increasing the overall third target heat dissipation requirement, which can control the electric pump to work at a greater power, and cooperate with the action of adjusting the opening degree of the target three-way valve to the third target opening degree, thereby improving the heat dissipation effect of the second vehicle component.

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

[0189] Step D, when the first component operating parameter of the first vehicle component meets the fourth preset condition and lasts for longer than the second preset time length, the cooling system control unit adjusts the opening degree of the target three-way valve from the third target opening degree to the third opening degree.

[0190] The first component operating parameter of the first vehicle component meeting the fourth preset condition and lasting for longer than the second preset time length indicates that the heat dissipation requirement of the first vehicle component increases sharply, and at this time, the intensity of heat dissipation of the first cooling system needs to be increased. The fourth preset condition and the second preset time length are set by technicians according to actual conditions, for example, the second preset time length is set to 90s, and the present application embodiment is not limited to this. Adjusting the opening degree of the target three-way valve from the second target opening degree to the third opening degree means adjusting the flow of the cooling liquid in the first cooling loop and the second cooling loop from the second cooling loop being greater than the first cooling loop to the first cooling loop being equal to the second cooling loop, so as to realize uniform heat dissipation of the first cooling system and the second cooling system.

[0191] For example, when the first heat dissipation requirement determination parameter in the first component operating parameter meets the fourth preset condition and lasts for longer than the second preset time length, the cooling system control unit adjusts the opening degree of the target three-way valve from the second target opening degree to the third opening degree.

[0192] For example, when the first component operating parameter includes the actual intake temperature of the engine, and the actual intake temperature is greater than or equal to the actual intake temperature threshold and lasts for longer than the second preset time length, the cooling system control unit adjusts the opening degree of the target three-way valve from the second target opening degree to the third opening degree 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 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 adjusts the opening degree of the target three-way valve to the third opening degree, and the third opening degree is the opening degree of the first cooling loop in which the flow of the cooling liquid is equal to that of the second cooling loop.

[0194] Wherein, when neither the first vehicle component nor the second vehicle component is working, the opening degree of the target three-way valve is adjusted to a third opening degree, so as to adjust the opening degree of the target three-way valve in time 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] Wherein, when neither the first vehicle component nor the second vehicle component is working, there is no heat dissipation demand, and the electric pump is controlled to stop working to save energy.

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

[0198] Through the technical solutions provided by the embodiments of the present application, the first component working parameter of the first vehicle component and the second component working parameter of the second vehicle component are obtained. The first component working parameter and the second component working parameter are used to determine the target heat dissipation mode and adjust the opening degree of the target three-way valve to the first target opening degree corresponding to the target heat dissipation mode, so as to realize dynamic management of the flow direction of the cooling liquid. Based on the target heat dissipation mode, the first target heat dissipation demand in the first 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, so as to realize heat dissipation control of two cooling systems by using one electric pump, which is low in cost.
