DETAILED DESCRIPTION

[0079] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0080] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0081] It should be noted that, for example, 11-1 in the drawings of the present disclosure indicates that component 11 belongs to component 1, for example, Fig. 9 31-3 indicate that the first driving circuit belongs to the first control circuit, and other similar reference numerals appearing in the drawings also follow the above description.

[0082] The embodiment of the present application provides a vehicle 1000. Figure 1 As shown, the vehicle 1000 includes: an on-board module 200 and a control system 300. The on-board module 200 is coupled to the control system 300.

[0083] It can be understood that the vehicle-mounted module 200 is a general term for various electronic devices and systems installed on the vehicle 1000. The vehicle-mounted module 200 is responsible for collecting vehicle 1000 operating data, executing control instructions, and providing information and entertainment functions required by the driver and passengers.

[0084] Exemplarily, the vehicle-mounted module 200 may be a vehicle controller.

[0085] The control system 300 is the core part of the vehicle 1000 that is responsible for processing data, making decisions, and controlling the operation of the vehicle-mounted modules 200. It is a combination of one or more electronic control units (ECUs). The ECU receives sensor data from the vehicle-mounted modules 200, performs real-time processing and analysis, and then issues control instructions based on preset algorithms and logic. The control system 300 is also responsible for coordinating the operations of the various vehicle-mounted modules 200 to ensure that they can operate in coordination to achieve the overall performance and functions of the vehicle 1000.

[0086] The coupling between the vehicle-mounted module 200 and the control system 300 is usually achieved through electrical connections, including wires, buses (such as CAN bus, LIN bus, etc.) and wireless communication methods (such as Bluetooth, Wi-Fi, etc., although wireless communication in vehicle-mounted systems is mainly used for non-critical data transmission).

[0087] The purpose of the coupling is to ensure that the control system 300 can accurately receive sensor data from the on-board modules 200 and can send control instructions to these modules.

[0088] Therefore, the on-board module 200 and the control system 300 in the vehicle 1000 are two interdependent and tightly coupled parts, and the on-board module 200 and the control system 300 work together to ensure the safe, reliable and efficient operation of the vehicle 1000.

[0089] The embodiment of the present application also provides a control system 300. Figure 1 As shown, the control system 300 includes: a heating circuit 61, a cooling circuit 71 and a controller 100. The controller 100 is coupled to the heating circuit 61 and the cooling circuit 71 respectively.

[0090] The heating circuit is activated to provide heat when the ambient temperature in the vehicle is lower than the set value, thereby increasing the ambient temperature.

[0091] The cooling circuit 71 is activated when the ambient temperature in the vehicle is higher than a set value to absorb or transfer heat, thereby lowering the ambient temperature.

[0092] The controller 100 is responsible for receiving signals from the temperature sensor and, based on the comparison of these signals with the preset temperature value, deciding whether to activate the heating circuit or the cooling circuit 71, or keep both of them off. The controller 100 continuously monitors the current temperature of the system or environment. When the current temperature is lower than the set value, the controller 100 sends a signal to activate the heating circuit until the temperature reaches or exceeds the set value. When the current temperature is higher than the set value, the controller 100 sends a signal to activate the cooling circuit 71 until the temperature drops below the set value. If the temperature is within the allowable range of the set value, the controller 100 will keep both the heating circuit and the cooling circuit 71 off to save energy. The temperature regulation of the vehicle 1000 is achieved by precisely controlling the temperature and keeping the temperature stable.

[0093] In some embodiments, the controller 100 includes a housing 110 and an integrated substrate, and the integrated substrate is coupled to the heating circuit 61 and the cooling circuit 71 respectively.

[0094] The housing 110 is the external structure of the controller 100 and mainly plays the role of protection and support.

[0095] Exemplarily, the housing 110 is made of a material having good insulation, heat resistance, fire resistance and other properties to ensure the safety and stability of the controller 100 during operation.

[0096] The integrated substrate is the core component of the controller 100 and carries the main functions of the circuit. The integrated substrate integrates circuit elements, connecting lines, etc. through a specific process to form a compact and efficient circuit structure. In this description, the integrated substrate is coupled to the heating circuit and the cooling circuit 71 respectively, and the working state of the heating circuit and the cooling circuit 71 can be controlled as needed.

[0097] Through the above configuration, the controller 100 can operate efficiently, stably and safely.

[0098] In some embodiments, the control system 300 includes a heater 6 and a compressor 7. The heater 6 includes a heating circuit 61, and the compressor 7 includes a cooling circuit 71.

[0099] The heater 6 is used for heating, and the heater 6 contains a heating circuit 61. The heating circuit 61 is the core of the heater 6 and is responsible for generating heat.

[0100] The compressor 7 contains a refrigeration circuit 71 for driving the compressor 7 to work. The refrigeration circuit 71 is responsible for driving the compressor 7 to achieve the function of refrigeration or gas compression.

[0101] In a traditional air conditioning system, the compressor 7 and the heater 6 usually work relatively independently. The compressor 7 is mainly responsible for the refrigeration cycle, which reduces the temperature inside the vehicle by compressing the refrigerant, while the heater 6 is used for heating, which generates heat by consuming electrical energy to increase the temperature inside the vehicle. The compressor 7 and the heater 6 are often also independent in control, each with independent control logic and sensor system, which increases the complexity of the entire thermal management system and reduces reliability.

[0102] However, in the heat pump system, the common use conditions of the compressor 7 and the heater 6 have increased. The heat pump system is an efficient heating / cooling system that can achieve both cooling and heating functions by changing the circulation direction of the refrigerant. In the heating mode, the compressor 7 still plays the role of compressing the refrigerant, but the direction of the refrigerant circulation is opposite to that in the cooling mode, thereby absorbing the heat from the outside and releasing it into the vehicle. Under certain working conditions, in order to further improve the heating efficiency or meet specific heating needs, the heater 6 will work simultaneously with the compressor 7 to provide additional heat.

[0103] In the controller 100, although the compressor 7 and the heater 6 have different control logics and algorithms, they do have certain similarities to some extent. For example, both require precise temperature control and sensor feedback to achieve efficient energy conversion and regulation. In addition, with the development of automobile intelligence, the controller 100 is also increasingly inclined to integration and networking in order to realize more complex thermal management strategies and fault diagnosis functions.

[0104] Based on this, the present application provides a controller 100, such as Figure 2 As shown, it includes: a processor 5, a first power supply circuit 1, a first control circuit 3 and a second control circuit 4.

[0105] The first control circuit 3 is coupled to the first power supply circuit 1 and the processor 5 respectively, and is also used to couple to the heating circuit 61 .

[0106] The second control circuit 4 is coupled to the first power supply circuit 1 and the processor 5 respectively, and is also used to couple to the cooling circuit 71 .

[0107] The processor 5 is configured to: in response to a received control instruction, convert the first voltage input by the first power supply circuit 1 into a second voltage for driving the heating circuit 61 to operate through the first control circuit 3, and / or, in response to a received control instruction, convert the third voltage input by the first power supply circuit 1 into a fourth voltage for driving the refrigeration circuit 71 to operate through the second control circuit 4.

[0108] The processor 5 is a core component of the controller 100 and is responsible for receiving, parsing and executing control instructions. According to the instructions, the first control circuit 3 or the second control circuit 4 adjusts the voltage to drive the heating circuit 61 or the cooling circuit 71.

[0109] The first power supply circuit 1 provides power for the controller 100 , provides a stable power input, provides electrical energy for the entire controller 100 and its connected circuits, and converts voltage for the heating and cooling circuit 71 .

[0110] Exemplarily, the first power supply circuit 1 may be a high-voltage power supply loop.

[0111] According to the instruction of the processor 5 , the first control circuit 3 is responsible for converting the input first voltage into a second voltage suitable for the operation of the heating circuit 61 , so that the heating circuit 61 can operate at an appropriate voltage.

[0112] According to the instruction of the processor 5 , the second control circuit 4 is responsible for converting the input third voltage into a fourth voltage suitable for the operation of the refrigeration circuit 71 to meet the operation requirements of the refrigeration circuit 71 .

[0113] Exemplarily, the processor 5 may be a main chip (MCU).

[0114] Through the above-mentioned configuration, compared with the situation where the compressor 7 and the heater 6 each have independent controllers 100, the number of controllers 100 is reduced, the utilization rate of components is improved, and the communication and interaction between the controllers 100 are reduced; and the controller 100 of the present application integrates multiple components including a processor 5, a first power supply circuit 1, a first control circuit 3 and a second control circuit 4, thereby achieving a high degree of functional integration; and according to the received control instructions, the processor 5 can flexibly adjust and control the working state of the heating and cooling circuit 71, so that the controller 100 can meet different temperature control requirements and improve the reliability of the controller 100; and, through the reasonable configuration of the control circuit and the processor 5, the function of the controller 100 can be expanded, and the reliability of the controller 100 can be further improved; and the control strategy can also be flexibly adjusted according to different requirements, so as to be suitable for a variety of control scenarios.

[0115] In some embodiments, Figure 3-4 As shown, the first control circuit 3 includes a first drive circuit 31 and a first switch circuit 32. The second control circuit 4 includes a second drive circuit 41 and a second switch circuit 42.

[0116] like Figure 3 As shown, the first switch circuit 32 is coupled to the first power supply circuit 1 and the first drive circuit 31 respectively, and is also used to couple to the heating circuit 61 .

[0117] like Figure 4As shown, the second switch circuit 42 is coupled to the first power supply circuit 1 and the second drive circuit 41 respectively, and is also used to couple to the cooling circuit 71 .

[0118] The first driving circuit 31 and the second driving circuit 41 are respectively coupled to the processor 5 .

[0119] Exemplarily, the first driving circuit 31 and the second driving circuit 41 may be IGBT drivers.

[0120] It can be understood that the first drive circuit 31 in the first control circuit 3 is responsible for controlling the opening and closing of the first switch circuit 32, thereby controlling the on and off of the heating circuit 61. The first switch circuit 32 is connected between the first power supply circuit 1 and the first drive circuit 31, and is also connected to the heating circuit 61, that is, when the first drive circuit 31 issues an instruction, the first switch circuit 32 will be opened or closed, thereby allowing or preventing current from passing through the heating circuit 61.

[0121] The second drive circuit 41 of the second control circuit 4 is responsible for controlling the opening and closing of the second switch circuit 42, thereby controlling the on and off of the refrigeration circuit 71. The second switch circuit 42 is connected between the first power supply circuit 1 and the second drive circuit 41, and is also connected to the refrigeration circuit 71, that is, when the second drive circuit 41 issues an instruction, the second switch circuit 42 will be opened or closed, thereby allowing or preventing current from passing through the refrigeration circuit 71.

[0122] That is, when the processor 5 detects that the ambient temperature is lower than the set value, it will send an instruction to the first drive circuit 31 to activate the first switch circuit 32, thereby allowing current to pass through the heating circuit 61 to increase the ambient temperature. On the contrary, when the processor 5 detects that the ambient temperature is higher than the set value, it will send an instruction to the second drive circuit 41 to activate the second switch circuit 42, thereby allowing current to pass through the cooling circuit 71 to reduce the ambient temperature.

[0123] Through the above-mentioned settings, the controller 100 can flexibly control the heating and cooling systems through the coordinated work of the first control circuit 3 and the second control circuit 4, thereby achieving precise control of the ambient temperature; at the same time, through the settings of the first switch circuit 32 and the second switch circuit 42, the system can efficiently switch the heating and cooling modes according to the instructions of the processor 5, thereby meeting different temperature control requirements and further improving the reliability of the controller 100.

[0124] In some embodiments, the first switch circuit 32 includes at least one insulated gate bipolar transistor IGBT.

[0125] It can be understood that the main function of the first switching circuit 32 is to control the on and off of the current to achieve control of the heating circuit 61. It can quickly switch the state of the heating circuit 61 according to the instructions of the processor 5. IGBT, as an element connecting the battery and the heating circuit 61, can accurately control the switching of the current to ensure that the heating circuit 61 obtains an appropriate amount of current when needed, and effectively controls the switching of high voltage and high current. It is suitable for driving the heating circuit 61. The use of IGBT can improve the efficiency of the switching circuit and reduce energy loss. At the same time, it can withstand higher voltage and current to ensure the stable operation of the heating circuit 61; and the fast switching characteristics of the IGBT make the heating process more precise, which helps to achieve better temperature control. Therefore, the above setting enables the controller 100 to quickly respond to the instructions of the processor 5 and achieve precise control of the heating process.

[0126] In some embodiments, the first switch circuit 32 includes at least two cascaded insulated gate bipolar transistors (IGBTs).

[0127] It can be understood that by cascading multiple IGBTs, control of higher power or voltage can be achieved, so that the first switch circuit 32 can operate under conditions higher than the rated voltage of a single IGBT; moreover, two or more IGBTs can work in series to increase the withstand voltage and reduce the risk of short-circuit failure (for example, short-circuit failure of two IGBTs at the same time), thereby improving the reliability of the entire controller 100 and meeting the requirements of multiple temperature zones of the entire vehicle ( Figure 5 The temperature zones shown in FIG. 1 are double temperature zones, which can be increased or decreased according to actual needs to meet: single temperature zone, double temperature zones, three temperature zones, four temperature zones, etc.). Therefore, through the above settings, the control of the controller 100 on the heating circuit 61 can be effectively improved, the response speed and reliability of the controller 100 can be enhanced, and the heating circuit 61 can be ensured to operate stably and efficiently.

[0128] In some embodiments, Figure 5 As shown, the controller 100 further includes: a first detection circuit 8 and a second detection circuit 9 .

[0129] The first detection circuit 8 is coupled to the processor 5. The first detection circuit 8 includes at least one of the following: a first temperature detection circuit, a second temperature detection circuit, or a first drive voltage detection circuit. The first temperature detection circuit is used to detect the temperature of the first switch circuit 32, the second temperature detection circuit is used to detect the temperature of the heating circuit 61, and the first drive voltage detection circuit is used to detect the drive voltage of the first switch circuit 32.

[0130] The second detection circuit 9 is coupled to the processor 5. The second detection circuit 9 includes at least one of the following: a third temperature detection circuit or a second drive voltage detection circuit. The third temperature detection circuit is used to detect the temperature of the second switch circuit 42, and the second drive voltage detection circuit is used to detect the drive voltage of the second switch circuit 42.

[0131] It can be understood that the first detection circuit 8 is coupled to the processor 5 so that the processor 5 can obtain the detected temperature and voltage information in real time and make corresponding control adjustments. Among them, the first temperature detection circuit is used to detect the temperature of the first switch circuit 32. Excessive temperature may cause IGBT or circuit failure, which can ensure the safe and stable operation of the first switch circuit 32. The second temperature detection circuit is used to detect the temperature of the heating circuit 61 to ensure that the heating process does not exceed the safe operating temperature, and the heating intensity can also be adjusted to meet different needs. The first drive voltage detection circuit is used to monitor the drive voltage of the first switch circuit 32 to ensure that the IGBT operates within a reasonable voltage range, thereby improving efficiency and reducing the risk of damage.

[0132] The second detection circuit 9 is coupled to the processor 5 to ensure the normal operation of the refrigeration system, wherein the third temperature detection circuit is used to detect the temperature of the second switch circuit 42 to ensure that the refrigeration system operates within a safe temperature range to prevent equipment failure. The second drive voltage detection circuit is used to monitor the drive voltage of the second switch circuit 42 to keep the system in an optimal working state.

[0133] Therefore, through the above settings, the first detection circuit 8 and the second detection circuit 9 both provide real-time temperature and voltage monitoring data for the processor 5 to analyze and adjust the heating or cooling mechanism as needed to ensure the safety and reliability of the controller 100.

[0134] In some embodiments, Figure 5 As shown, the first power supply circuit 1 includes a first filter circuit 11 and a first connector 12 .

[0135] The first filter circuit 11 is coupled between the first control circuit 3 and the first connector 12. The first connector 12 is used to couple the first filter circuit 11 to an external first power supply.

[0136] It can be understood that the first power supply circuit 1 is mainly composed of two parts: the first filter circuit 11 and the first connector 12. Among them, the first filter circuit 11 is located between the first control circuit 3 and the first connector 12, and plays a role in filtering the power supply to ensure the stability and reliability of the power supply. By filtering out the clutter and interference in the power supply, the first filter circuit 11 can effectively protect the subsequent circuit from damage and improve the performance of the entire system. The first connector 12 transmits the filtered power signal to the external device, and also provides a way for the external device to access the system power supply. The first connector 12 can ensure the safety and stability of the power connection through the convenience of plugging and unplugging and the reliability of contact.

[0137] Therefore, through the coordinated work of the first power supply circuit 1 through the first filter circuit 11 and the first connector 12, the quality of the power supply is optimized, reliable connection and stable power supply with the external first power supply are achieved, stable voltage input is ensured to the controller 100, and safety and reliability are enhanced, providing a strong guarantee for the normal operation of the controller 100.

[0138] In some embodiments, Figure 5 As shown, the controller 100 further includes: a first current sampling circuit 81 and a second current sampling circuit 91 .

[0139] The first current sampling circuit 81 is coupled between the processor 5 and the first switch circuit 32 .

[0140] The second current sampling circuit 91 is coupled between the processor 5 and the second switch circuit 42 .

[0141] It can be understood that the first current sampling circuit 81 is located between the processor 5 and the first switching circuit 32, so that the processor 5 can monitor the current condition of the first switching circuit 32 in real time and feed back the current value to the processor 5. The processor 5 can adjust the operating state of the first switching circuit 32 according to the sampled current data, such as automatically reducing the load or cutting off the circuit when the current exceeds a preset value to prevent overload or damage.

[0142] The second current sampling circuit 91 is also located between the processor 5 and the second switch circuit 42, so that the processor 5 can monitor the current condition of the second switch circuit 42 in real time and feed back the current value to the processor 5. The processor 5 can optimize the working state of the refrigeration circuit 71 based on the sampled current data, such as adjusting the refrigeration power or switch state in time when the current changes, to ensure the safe and efficient operation of the refrigeration circuit 71.

[0143] Through the above settings, the first current sampling circuit 81 and the second current sampling circuit 91 provide the controller 100 with key current monitoring capabilities, so that the processor 5 can acquire and analyze current data in real time, enhance the dynamic adjustment capability and protection function of the controller 100, ensure the safety and efficiency of the heating and cooling process, improve the reliability and safety of the controller 100, and thus ensure the stable operation of the entire controller 100.

[0144] In some embodiments, a first safety capacitor X1 is coupled between the first filter circuit 11 and the first current sampling circuit 81. A second safety capacitor X2 is coupled between the first filter circuit 11 and the second current sampling circuit 91. A third safety capacitor Y1 is coupled between the first filter circuit 11 and the ground point in the controller 100.

[0145] A fourth safety capacitor Y2 is coupled between the first current sampling circuit 81 and a ground point in the controller 100 .

[0146] A fifth safety capacitor Y3 is coupled between the second current sampling circuit 91 and a ground point in the controller 100 .

[0147] Exemplarily, the first safety capacitor X1, the second safety capacitor X2, the third safety capacitor Y1, the fourth safety capacitor Y2 and the fifth safety capacitor Y3 may be film capacitors having good high temperature resistance.

[0148] Exemplarily, the first safety capacitor X1 and the second safety capacitor X2 may be X capacitors.

[0149] Exemplarily, the third safety capacitor Y1 , the fourth safety capacitor Y2 , and the fifth safety capacitor Y3 may be Y capacitors.

[0150] For example, Figure 7 As shown, when the controller 100 includes a refrigeration circuit 71, a first safety capacitor X1 is coupled between the first filter circuit 11 and the first current sampling circuit 81. A third safety capacitor Y1 is coupled between the first filter circuit 11 and a ground point in the controller 100. A fourth safety capacitor Y2 is coupled between the first current sampling circuit 81 and a ground point in the controller 100.

[0151] It can be understood that the first safety capacitor X1 provides a stable power input for the first current sampling circuit 81, and at the same time plays a role in isolation and improving anti-interference ability, ensuring the accuracy of current sampling. The second safety capacitor X2 can stabilize the power supply and prevent unnecessary signal interference, ensuring the reliability of the current information received by the processor 5. The third safety capacitor Y1 provides grounding protection for the first filter circuit 11, ensuring the electrical safety of the system, and also helps to reduce the impact of noise on the first filter circuit 11 and improve stability. The fourth safety capacitor Y2 plays a role in filtering and stabilizing the first current sampling signal, and also ensures that the first current sampling circuit 81 is safely grounded, reducing the current measurement error caused by the ground loop. The fifth safety capacitor Y3 can ensure that the signal of the second current sampling circuit 91 is stable and safe, so that the controller 100 can resist the fluctuations and interference of the first power supply circuit 1 of the whole vehicle, mainly for the battery pulse heating function, thereby improving the monitoring accuracy and reliability of the entire controller 100 and realizing platform development.

[0152] Therefore, through the above settings, the configuration of multiple safety capacitors effectively reduces power supply noise and signal interference, ensuring that the first current sampling circuit 81 and the second current sampling circuit 91 can accurately reflect the actual current state; it can also absorb excess current when the voltage exceeds the safety threshold to prevent overvoltage from damaging circuit components, thereby enhancing the safety and reliability of the controller 100.

[0153] In some embodiments, Figure 1 to Figure 4 As shown, the controller 100 further includes: a second power supply circuit 2. The second power supply circuit 2 is coupled to the processor 5, and is used to couple the processor 5 to an external second power supply.

[0154] Exemplarily, the second power supply circuit 2 may be a low-voltage power supply circuit.

[0155] It can be understood that the second power supply circuit 2 is coupled to the processor 5 to ensure that the processor 5 can obtain stable voltage and current from the external second power supply, so that the processor 5 can maintain stable operation under various circumstances, thereby improving the safety and reliability of the system.

[0156] In some embodiments, Figure 4 As shown, the second power supply circuit 2 includes a second filter circuit 21 and a second connector 22. The second filter circuit 21 is coupled between the second connector 22 and the processor 5.

[0157] It can be understood that the second filter circuit 21 has good filtering characteristics, can effectively reduce the noise introduced by the external power supply, can filter the received power supply voltage, smooth the output voltage, reduce the noise and interference in the power supply voltage, ensure that the processor 5 obtains stable power supply, help protect the processor 5 from power supply fluctuations, and enhance the anti-interference ability of the system. The second connector 22 is used to connect the external second power supply to the second filter circuit 21, ensuring the safety of the power supply when connecting and disconnecting, helping to reduce equipment damage caused by improper operation, and ensuring reliable input of power.

[0158] Therefore, through the above settings, the quality of the power supply voltage for the controller 100 can be improved, damage to the processor 5 due to voltage spikes or troughs can be avoided, the accuracy of data and the timeliness of the response of the processor 5 can be improved, thereby further improving the reliability of the entire system.

[0159] In some embodiments, the controller 100 further includes a communication circuit 10 . A first end of the communication circuit 10 is coupled to the processor 5 , and a second end of the communication circuit 10 is used to couple to the vehicle-mounted module 200 .

[0160] It can be understood that the communication circuit 10 is a bridge for the controller 100 to exchange information with the vehicle-mounted module 200, and can receive input data from the vehicle-mounted module 200 and send output data from the processor 5 to the vehicle-mounted module 200. A portion of the communication circuit 10 is directly connected to the processor 5 so that the processor 5 can send and receive data through the communication circuit 10. This connection is usually achieved through an internal bus or a dedicated interface. Another portion of the communication circuit 10 is connected to an interface of the external vehicle-mounted module 200, so that the communication circuit 10 communicates with the vehicle-mounted module 200.

[0161] Through the above settings, the controller 100 can efficiently collect and process information from various parts of the vehicle 1000, make corresponding control instructions, and then send the control instructions to the corresponding actuator through the communication circuit 10. Through flexible communication and data transmission capabilities, support is provided for the complexity and versatility of the vehicle 1000 control system 300.

[0162] In some embodiments, Figure 4 As shown, the communication circuit 10 includes a first communication sub-circuit 101 and a second communication sub-circuit 102 .

[0163] The first end of the first communication sub-circuit 101 and the first end of the second communication sub-circuit 102 are respectively coupled to the processor 5 .

[0164] The second end of the first communication sub-circuit 101 and the second end of the second communication sub-circuit 102 are respectively used to be coupled to the vehicle-mounted module 200 .

[0165] It can be understood that the first end of the first communication subcircuit 101 is coupled to the processor 5, so that the processor 5 can communicate with the external device through the first communication subcircuit 101. The second end of the first communication subcircuit 101 is used to couple to the vehicle-mounted module 200 to achieve data transmission and reception. The first end of the second communication subcircuit 102 is coupled to the processor 5, in parallel with the first communication subcircuit 101, to provide another communication path for the processor 5. The second end of the second communication subcircuit 102 is coupled to the vehicle-mounted module 200, and can exchange data with other components of the vehicle-mounted system.

[0166] By configuring two communication sub-circuits at the same time as mentioned above, the system can process multiple signals from the vehicle-mounted module 200 at the same time, thereby improving the bandwidth and efficiency of data transmission. If one of the communication sub-circuits fails, the other sub-circuit can take over immediately to ensure the continuous communication capability of the system, and provide a powerful communication interface for the controller 100, ensuring that the processor 5 can effectively conduct two-way data exchange with the vehicle-mounted module 200. This redundant and flexible structure improves the reliability and response speed of the controller 100.

[0167] In some embodiments, the first communication sub-circuit 101 is a LIN communication circuit 10 , and the second communication sub-circuit 102 is a CAN communication circuit 10 .

[0168] It can be understood that the first communication subcircuit 101 is a LIN (Local Interconnect Network) communication circuit 10. The LIN network usually adopts a master-slave structure, in which the master device is responsible for scheduling, and the slave devices on the bus transmit data according to the instructions of the master device. The LIN circuit design is relatively simple, the required hardware cost is low, and the single-host structure makes network design and implementation easy; and it is suitable for control tasks with low communication frequency and no high-speed response requirements.

[0169] The second communication subcircuit 102 is designed as a CAN (Controller Area Network) communication circuit. CAN communication adopts a multi-host structure. Each node can communicate with each other without the need for scheduling by the master node. The CAN protocol supports a priority mechanism to ensure that high-priority messages can be transmitted in a timely manner, which is suitable for critical applications that require timely response. The CAN network has a powerful error detection mechanism that can isolate problem nodes when errors occur to ensure the stability of the overall system.

[0170] Through the above settings, the controller 100 can effectively meet the communication requirements of different levels of the vehicle system. LIN supports simple and cost-effective control tasks, while CAN ensures high-speed and high-reliability communication between key components, thereby improving the communication flexibility of the controller 100.

[0171] Moreover, the communication circuit 10 is compatible with CAN and LIN, ensuring the platform development of the controller 100. The communication between the two is integrated into one controller 100. When the heat pump system needs to use the compressor 7 and the heater 6 at the same time, the communication mode of the compressor 7-controller 100-heater 6 is simplified to the communication mode of the integrated controller of the two-vehicle thermal management controller, thereby reducing the communication loop and the communication cycle, eliminating the technical barriers caused by the long communication cycle of the two independent controllers in the non-integrated solution, and facilitating the control and development of more complex thermal management systems. At the same time, the lines connecting the controller 100 to the compressor 7 and the heater 6 are simplified to the connecting lines within the controller 100, reducing the number of nodes and improving reliability.

[0172] For the above-mentioned controller 100, the control principle of the compressor 7 of the present application is: when the first power supply circuit 1, the second power supply circuit 2, the vehicle-mounted module 200, the controller 100, the compressor 7 and the heater 6 are connected, the controller 100 receives the signal from the vehicle-mounted module 200 and the signal from the second detection circuit 9, and controls the second drive circuit 41 through logical operations to realize the control of the second control circuit 4, thereby realizing the control of the compressor 7; Fig.10 In the figure, the circuits related to the communication circuit 10 are connected by dotted lines, and the second control circuit 4 is connected by thick solid lines.

[0173] For the above-mentioned controller 100, the control principle of the heater 6 of the present application is: when the first power supply circuit 1, the second power supply circuit 2, the vehicle-mounted module 200, the controller 100, the compressor 7 and the heater 6 are connected, the controller 100 receives the signal of the vehicle-mounted module 200 and the signal of the first detection circuit 8, and then controls the first drive circuit 31 through logical operation to realize the control of the first control circuit 3, thereby realizing the control of the heater 6; Fig. 9 In FIG. 1 , the circuits related to the communication circuit 10 are connected by dotted lines, and the first control circuit 3 is connected by thick solid lines. Figure 6 As shown, after adopting the integrated solution, the heater is only a core structure, which realizes control, communication, heating and other functions by connecting with the controller 100; the core structure development difficulty and development cycle are relatively short, and this integrated solution can better meet the requirements of short cycle and multiple configurations of the whole vehicle.

[0174] Based on the above, there are three control processes of the controller 100 of the present application:

[0175] 1. Independently control the operation of the compressor 7. When the first power supply circuit 1 and the second power supply circuit 2 are connected correspondingly, and the communication circuit 10 (CAN or LIN) is connected to the upper vehicle-mounted module 200 and the communication is correct, the processor 5 controls the second drive circuit 41 related to the compressor 7 according to the second detection circuit 9 and the communication circuit 10 signal, so that the compressor 7 can be operated in the refrigeration system. That is, after receiving the request signal for the independent operation of the compressor 7, the operation of the product is controlled and monitored according to the control specifications.

[0176] 2. Independently control the operation of the heater 6. When the first power supply circuit 1 and the second power supply circuit 2 are connected respectively and the communication circuit 10 (CAN or LIN) is connected to the upper vehicle-mounted module 200 and the communication is correct, the processor 5 controls the first drive circuit 31 related to the heater 6 according to the first detection circuit 8 and the communication circuit 10 signal to realize the heat conversion of the heater 6 assembly. That is, after receiving the request signal for the independent operation of the heater 6, the operation of the product is controlled and monitored according to the control specifications.

[0177] 3. Control the operation of the compressor 7 and the heater 6 at the same time. When the first power supply circuit 1 and the second power supply circuit 2 are connected respectively and the communication circuit 10 (CAN or LIN) is connected to the upper vehicle-mounted module 200 and the communication is correct, the processor 5 controls the first drive circuit 31 related to the heater 6 and the second drive circuit 41 related to the compressor 7 according to the signals of the first detection circuit 8, the second detection circuit 9 and the communication circuit 10, so as to realize the simultaneous operation of the compressor 7 and the heater 6. That is, the request signals for the operation of the heater 6 and the compressor 7 are received at the same time, and the operation of the product is controlled and monitored according to the control specifications.

[0178] Through the above, the communication, control, signal acquisition and other functions of the compressor 7 and the heater 6 can be implemented in the software or application layer, and modular development and matching can be carried out according to the requirements of the thermal management system.

[0179] Therefore, in terms of platformization, the controller 100 can realize the control of compressors 7 and heaters 6 of various specifications; in terms of performance, the controller 100 transfers the cost of the integrated (or shared) part to important or critical electrical components, improves the performance and reliability of such electrical components, and eliminates communication barriers; in terms of quality, the controller 100 transfers the cost of the integrated (or shared) part to important or critical characteristics, performs certain redundant designs, reduces failure modes, and improves quality performance; in terms of cost, the controller 100 simplifies the system principles and wiring harness principles of the entire vehicle, and reduces the cost of the entire vehicle.

[0180] In some embodiments, Figure 8As shown, a heat dissipation structure 120 and a first switch circuit 32 are disposed on the same surface of a housing 110 of the controller 100 , and the second switch circuit 42 is disposed on the heat dissipation surface 72 of the compressor 7 .

[0181] A heat dissipation structure 120 is provided on the same surface of the housing 110 of the controller 100, and the heat dissipation structure 120 is used to dissipate the heat generated by the controller 100. The first switch circuit 32 is also provided on the heat dissipation structure 120 to ensure that the first switch circuit 32 does not overheat when the heater operates independently. The second switch circuit 42 is provided on the heat dissipation surface 72 of the compressor 7, thereby realizing effective heat management and power supply control, and helping to ensure that the heater 6 and the compressor 7 can maintain a safe and stable working state while operating efficiently.

[0182] The embodiment of the present application provides a control method. Figure 2 , refer to Fig.11 , the control method includes: S1~S2.

[0183] S1: In response to the received control instruction, the first control circuit 3 converts the first voltage input by the first power supply circuit 1 into a second voltage for driving the heating circuit 61 to work.

[0184] S2: In response to the received control instruction, the second control circuit 4 converts the third voltage input by the first power supply circuit 1 into a fourth voltage for driving the refrigeration circuit 71 to work.

[0185] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
