[0047] In the embodiments of the present application, Figure 1 This is one of the flow charts of a control method of a thermal management system provided in an embodiment of the application. The method may include S101 to S105:

[0048] S101. When the scene service layer receives a first request for at least one scene, the scene service layer sends a first request to the system service layer, where the first request instructs the thermal management system to work.

[0049] In an embodiment of the present application, the thermal management system includes a scene service layer, a system service layer, an enhanced service layer, an atomic service layer, an abstract service layer and a basic service layer.

[0050] In an embodiment of the present application, the scene service layer may include multiple scenes, different scenes correspond to different thermal management requirements, and thermal management of the scene can be achieved by receiving a first request of at least one scene.

[0051] In some embodiments, the first request refers to a request for performing thermal management on a scene. The first request may be for performing thermal management on one scene, or the first request may be for performing thermal management on multiple scenes.

[0052] In an embodiment of the present application, multiple scenes of the scene service layer are mainly arranged and set according to the requirements of the thermal management system, customized requirements and special functional requirements. When the scene service layer receives a first request for at least one scene, the first request is sent to the system service layer through the scene service layer.

[0053] S102: When the system service layer receives the first request, the system service layer determines a first management object by calling the system service layer, where the first management object indicates an object that needs to be thermally managed.

[0054] In the embodiments of the present application, there is no limitation on the first management object. In short, it is an object that can participate in thermal management. In some embodiments, the first management object may include battery thermal management, equipment thermal management, passenger compartment thermal management, thermal management energy management, thermal management state management, etc. Equipment thermal management may include electric drive thermal management, engine thermal management, and electronic control thermal management, etc.

[0055] In some embodiments, the system service layer mainly abstracts the functions of the thermal management system. The system service layer includes multiple management objects. The thermal management of a scene in the scene service layer can be achieved by calling multiple management objects in the system service layer.

[0056] In an embodiment of the present application, the scene service layer can implement thermal management of the scene under the first request by calling the first management object of the system service layer.

[0057] In some embodiments, the scenario service performs scenario orchestration by calling battery thermal management, device thermal management, and passenger compartment thermal management.

[0058] S103: Based on the first management object, call the enhanced service layer through the system status management object of the system service layer to determine at least one control unit in the enhanced service layer.

[0059] In an embodiment of the present application, in addition to the first management object, the system service layer also includes a system status management object. The system status management object judges the calling information of the first management object again based on the status, energy and other information of the thermal management system to determine whether the first management object can be called.

[0060] In some embodiments, the enhanced service layer may provide an interface for system service calls, and the control unit in the enhanced service layer may be called by multiple management objects in the system service layer at the same time.

[0061] In the embodiment of the present application, the control unit in the enhanced service layer is not limited, and in short, it is a unit that can control the thermal management actuator. The control unit mainly completes the control of the actuator, and the control logic is implemented in the enhanced service layer.

[0062] In some embodiments, the control units in the enhanced service layer may include a compressor control unit, an expansion valve control unit, a fan control unit, a water pump control unit, a water valve control unit, and a thermal management state control unit.

[0063] In an embodiment of the present application, based on the first management object, the enhanced service layer is called through the system status management object of the system service layer. After the enhanced service layer performs priority arbitration, input parameter verification and other operations on the call from the system service layer, at least one control unit in the enhanced service layer is determined.

[0064] S104, based on at least one control unit, determining a first executor that executes a task of at least one control unit by calling an atomic service layer;

[0065] S105 . Based on the first actuator, drive the first driving hardware through the abstract service layer and / or the basic service layer, where the first driving hardware is used to participate in the operation of the thermal management system.

[0066] In the embodiment of the present application, the atomic service layer mainly calls the open interface of the enhanced service layer and calls at least one first executor in the atomic service layer.

[0067] In the embodiment of the present application, the first actuator is not limited, and in short, it is an actuator that can perform thermal management.

[0068] In some embodiments, the first actuator may include a compressor atom, an expansion valve atom, a fan atom, a water pump atom, a stop valve atom, etc.

[0069] Exemplarily, the temperature atomic service provides temperature signals for the thermal management system, the pressure atomic service provides pressure signals for the thermal management system, and the basic service provides signals provided by other controllers required in the compressor calculation process, such as CAN or LIN signals.

[0070] In some embodiments, the atomic service layer receives and converts the compressor speed, expansion valve opening, fan speed, water valve angle and other signals input by the enhanced service layer, and sends the control instruction of the first actuator to the first actuator by calling the abstract service layer or the basic service layer. As an isolation layer, the atomic service layer can shield the influence of the abstract service layer on the enhanced service layer and the system service layer.

[0071] Exemplarily, the compressor control unit is called to issue a speed request that satisfies the cooling of the passenger compartment and the battery. During this process, the compressor control calls temperature atoms, pressure atoms, and basic services to participate in the calculation.

[0072] In the embodiment of the present application, the abstract service layer and / or the basic service layer can drive the corresponding first driving hardware according to the first actuator. The first driving hardware is used to participate in the operation of the thermal management system and implement the thermal management of the first request.

[0073] It can be understood that, when the scene service layer receives the first request of at least one scene, the scene service layer sends the first request to the system service layer, determines the first management object of the system service layer, calls the enhanced service layer through the system state management object of the system service layer, determines at least one control unit in the enhanced service layer, determines the first actuator that executes the task of at least one control unit through the call to the atomic service layer, and drives the first driver hardware through the abstract service layer and / or the basic service layer based on the first actuator, and the first driver hardware is used to participate in the work of the thermal management system. In the thermal management system, the minimum functional logic is encapsulated into a service, and a scene service layer, a system service layer, an enhanced service layer, an atomic service layer, an abstract service layer and a basic service layer are formed. In the thermal management system, the functions of the thermal management system are abstracted and the core functions are packaged, so that the scene service can meet the scene arrangement by calling the corresponding functional modules, and then, the thermal management system can be customized according to user needs. The service interface of each level is called to realize the call between different levels, and then the interaction of different functional logics and data is realized, and the personalized intelligent customization of the thermal management system is realized, which improves the flexibility and openness of the thermal management system.

[0074] In some embodiments, Figure 2 As shown, S103 may include S201 to S203:

[0075] S201. Acquire first information of a system energy management object of a system service layer through a system status management object, where the first information indicates energy of a thermal management system.

[0076] In the embodiment of the present application, the system service layer includes not only the first management object and the system state management object, but also the system energy management object, which manages the energy state of the thermal management system.

[0077] In the embodiment of the present application, the first information is information generated after the system energy management object manages the energy state of the thermal management system, and the first information indicates the current energy state of the thermal management system.

[0078] In some embodiments, the system status management object of the system service layer can judge the current energy of the thermal management system based on the first information, and determine whether to perform thermal management on the first management object.

[0079] S202. Acquire second information fed back by the enhanced service layer through the system status management object; the second information indicates the high pressure state, operation state and fault state of the thermal management system.

[0080] In the embodiment of the present application, the second information indicates the collection of the high pressure state, the operating state and the fault state of the current thermal management system. The control unit in the enhanced service layer can generate the second information and send the second information to the system state management object of the system service layer, so that the system state management object can determine whether to call the control unit in the enhanced service layer according to the second information.

[0081] S203: Based on the first management object, the first information, and the second information, call the enhanced service layer through the second management object of the system service layer to determine at least one control unit in the enhanced service layer.

[0082] In an embodiment of the present application, the system status management object of the system service layer determines the current energy of the thermal management system based on the first information, and determines the current state (high voltage state, operating state, and fault state) of the thermal management system based on the second information, and determines whether to call the control unit of the enhanced service layer required by the first management object through comprehensive consideration of the current energy and state of the thermal management system.

[0083] For example, a schematic diagram of a thermal management system is shown in FIG. Figure 3As shown, the scenario service layer includes scenario 1, scenario 2, scenario 3 and scenario 4; the first management object in the system service layer includes battery thermal management 10, electric drive thermal management 11, and passenger compartment thermal management 12; the system energy management object in the system service layer is system energy management 13; and the system state management object in the system service layer is system state management 14; the control unit in the enhanced service layer includes compressor control 20, expansion valve control 21, fan control 22, water pump control 24, and thermal management state control 25. The system state management 14 receives information from the first management object, the first information from the system energy management 13, and the second information fed back by the thermal management state control 25 in the enhanced service layer, and determines the call to the enhanced service layer after comprehensive judgment. The first actuator in the atomic service layer includes compressor atom 31, expansion valve atom 32, water pump atom 33, stop valve atom 34, fan atom 35, water valve atom 36, temperature atom 37 and pressure atom 38; the abstract service layer mainly communicates with the hardware through the I / O interface; the basic service layer can transfer information between the system service layer, enhanced service layer and atomic service layer.

[0084] It can be understood that the first information of the system energy management object of the system service layer is obtained through the system status management object, the second information fed back by the enhanced service layer is obtained through the system status management object, and based on the first management object, the first information and the second information, the enhanced service layer is called through the second management object of the system service layer to determine at least one control unit in the enhanced service layer. Based on this, the system status management object can judge the current energy of the thermal management system according to the first information, and judge the current state (high voltage state, operating state and fault state) of the thermal management system according to the second information, so that the system status management object can fully obtain the current information of the thermal management system and make a comprehensive judgment whether it can safely and reasonably call the control unit of the enhanced service layer, thereby improving the safety and effectiveness of the thermal management system control.

[0085] In some embodiments, the method further comprises:

[0086] The third information is sent to the system service layer, the enhanced service layer, and the atomic service layer through the basic service layer, and the third information represents general functional information related to the thermal management system.

[0087] In the embodiment of the present application, the third information is not limited. In short, it is general functional information that can be used in the system service layer, enhanced service layer, and atomic service layer.

[0088] In some embodiments, the third information may be information such as a current threshold, a temperature threshold, etc.

[0089] In an embodiment of the present application, the third information can be sent to the system service layer, the enhanced service layer, and the atomic service layer through the basic service layer.

[0090] It can be understood that general functional information (third information) representing the thermal management system is sent to the system service layer, enhanced service layer, and atomic service layer through the basic service layer, and the general functional information is set in the basic service layer, so that when it is needed at different levels, the basic service layer can be called to obtain the third information, thereby avoiding repeated setting of general functions at each level and avoiding code redundancy at different levels. In turn, the modularity and reusability of the thermal management system are improved, and the efficiency of thermal management system development is improved.

[0091] In some embodiments, the method further comprises:

[0092] The fourth information sent by at least one service layer among the system service layer, the enhanced service layer, and the atomic service layer is received through the basic service layer, and the fourth information is sent to any service layer among the system service layer, the enhanced service layer, and the atomic service layer, wherein the fourth information indicates information transmitted between different service layers.

[0093] In the embodiment of the present application, there is mutual information (fourth information) transmission between the system service layer, the enhanced service layer, and the atomic service layer, and the basic service layer can realize information transmission across multiple layers.

[0094] In the embodiment of the present application, the fourth information is not limited. In short, it is information that can be transmitted between the system service layer, the enhanced service layer, and the atomic service layer.

[0095] In an embodiment of the present application, the fourth information may come from the basic service layer receiving system service layer, enhanced service layer, and at least one service layer of the atomic service layer, receive the fourth information through the basic service layer, and send the fourth information to the service layer that needs to be transmitted.

[0096] In some embodiments, the transmission of the fourth information may achieve cross-level transmission.

[0097] Exemplarily, the system service layer receives the fourth information sent by the system service layer, and sends the fourth information directly to the atomic service layer without passing through the enhanced service layer.

[0098] It can be understood that the basic service layer, as a communication medium of the thermal management system, can receive the fourth information sent by at least one service layer among the system service layer, the enhanced service layer, and the atomic service layer, and transmit the information to any service layer among the system service layer, the enhanced service layer, and the atomic service layer, thereby realizing communication between different levels in the thermal management system, including cross-layer communication, avoiding the need to transmit signals layer by layer, and improving the timeliness of the thermal management system.

[0099] In some embodiments, the method further comprises:

[0100] The notification information of the abstract service layer is received through the atomic service layer, and the notification information is converted into data to obtain first numerical information with a physical type; the notification information indicates electrical characteristic information; the first numerical information is used to participate in the logical control of the enhanced service layer.

[0101] In the embodiments of the present application, there is no limitation on the notification information. In short, it is information indicating electrical characteristics, such as voltage, current, resistance and other information. The notification information is generated by the abstract service layer. The abstract service layer may have a service layer of an I / O interface, which is connected to the hardware for thermal management through the I / O interface. Therefore, the type of the notification information matches the abstract service layer interface. For example, the notification information may be represented in binary.

[0102] In the embodiment of the present application, the first numerical information is not limited. In short, it is information that can participate in the logical control of the enhanced service layer, for example, numerical information of voltage and current.

[0103] In an embodiment of the present application, notification information of the abstract service layer is received through the atomic service layer, and the notification information is converted into numerical information required by the atomic layer (first numerical information with a physical type). That is to say, data type conversion can be achieved in the atomic service layer, and the notification information of the abstract service layer is converted into the first numerical information after data conversion, so that the enhanced service layer can obtain the first numerical information through the atomic service layer and use the first numerical information to perform logical control of the control unit.

[0104] It should be noted that the first actuator of the atomic service layer has hardware differences, including differences in control interfaces, control signal types, control ranges, etc. The atomic service layer mainly solves the problem of hardware differences of the first actuator by converting notification information into data.

[0105] For example, when the first actuator of the atomic service layer is a compressor atom, the compressor atom converts the physical value of the control signal according to the compressor hardware type. In the actual process, there are hardware differences such as differences in compressor manufacturers, control signals, and control ranges. In order to avoid such differences, it is necessary to convert the control signal according to the compressor hardware type and convert them into voltage control signals under the same range.

[0106] It can be understood that data type conversion can be achieved in the atomic service layer, and the notification information of the abstract service layer can be converted into first numerical information after data conversion, so that the control unit of the enhanced service layer can obtain the first numerical information that can be directly used through the atomic service layer for logical control. Based on this, the atomic service layer eliminates hardware differences through data conversion capabilities, thereby improving the feasibility and accuracy of control and signal transmission of the thermal management system.

[0107] In some embodiments, the method further comprises:

[0108] The first numerical information of the atomic service layer is received through the enhanced service layer.

[0109] In the embodiment of the present application, the atomic service layer can realize data type conversion, and the notification information of the abstract service layer is converted into the first numerical information after data conversion. The first numerical information of the atomic service layer is received through the enhanced service layer, so that the enhanced service layer can obtain the first numerical information through the atomic service layer, and use the first numerical information to perform logical control of the control unit.

[0110] Exemplarily, the enhanced service layer receives the voltage and current (first numerical information) of the atomic service layer, and performs logical control on the fan control unit and water valve control unit in the enhanced service layer according to the voltage and current, thereby controlling the fan speed and the switch status of the water valve.

[0115] In an embodiment of the present application, the atomic service layer may generate a first control instruction, where the first control instruction is used to drive at least one hardware so that the hardware can implement the thermal management of the first request.

[0116] In the embodiment of the present application, both the abstract service layer and the basic service layer can be called by the atomic service layer to send control instructions to the corresponding hardware to perform thermal management control. Among them, for the hardware controlled by CAN / LIN communication, the corresponding basic service is called to send the first control instruction to the corresponding control hardware, and for the hardware controlled by the VIU controller, the corresponding abstract service is called to send the first control instruction to the underlying driver, and the underlying driver controls the hardware action. In other words, the abstract service layer and / or the basic service layer are called according to the control type of the hardware.

The first control instruction is used to control the first actuator, and the first actuator drives the hardware participating in the first request. According to the type of the hardware, the service layer (abstract service layer and basic service layer) that meets the hardware communication requirements is selected to realize the communication requirements of different hardware, improve the compatibility of the thermal management system with hardware, and drive the first driver hardware through the abstract service layer to realize the separation of control and calculation of the abstract service layer, effectively avoid the disturbance caused by the first driver hardware to other levels, and enhance the accuracy and stability of the thermal management control logic.

[0118] In some embodiments, the method further comprises:

[0119] In the case where the abstract service layer and / or the basic service layer drives the first driving hardware, information of the first driving hardware is fed back to the atomic service layer.

[0120] In an embodiment of the present application, the abstract service layer and / or the basic service layer receives a call from the atomic service layer, which indicates the first driver hardware that the abstract service layer needs to drive, thereby determining the first driver hardware. By controlling the first driver hardware, the thermal management of the first request is implemented, and the abstract service layer and / or the basic service layer also feeds back the information of the first driver hardware to the atomic service layer, so that the abstract service layer can more accurately determine the first control instruction of the first actuator.

[0121] It can be understood that the information of the first driver hardware is fed back to the atomic service layer through the abstract service layer and / or the basic service layer, so that after the atomic service layer obtains the information of the first driver hardware, it can more accurately determine the first control instruction of the first actuator based on the information, thereby effectively improving the accuracy of the first control instruction.
