The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] It should be noted that the drawings provided in this embodiment only illustrate the basic concept of the present invention schematically. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, number, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0032] Please refer to Figure 1As shown in the figure, with the rapid development of new energy vehicles, the thermal management system, as a core component, plays a crucial role in the vehicle's performance, energy efficiency, and driving comfort. In the prior art, the thermal management system usually adopts a distributed layout, consisting of an electric compressor assembly, a heater assembly, and a thermal management controller independently. The electric compressor assembly includes a compressor controller and a compressor pump body, and the heater assembly includes a heater controller and a heater core. The high-voltage and low-voltage harnesses of the whole vehicle are respectively connected to the high- and low-voltage connectors of the compressor and the heater via connectors to achieve functions such as high-voltage power supply, high-voltage interlock, and low-voltage power supply. The thermal management controller controls the compressor and the heater through control lines to achieve the thermal management goal of the whole vehicle. However, the above-mentioned prior system has many drawbacks. On the one hand, the system integration degree is low, resulting in a large amount of redundancy in the harness and components, which not only directly increases the hardware cost, but also increases the harness length and complexity due to the distributed layout, thereby reducing the space utilization rate and production assembly efficiency of the whole vehicle; on the other hand, the complex harness connection also increases the risk of system failures, reduces the reliability and safety of the thermal management system, and is difficult to meet the growing requirements of the new energy vehicle market for high performance, high integration, and low cost of the thermal management system.

The integrated controller 20 is connected to the compressor pump body 30 and the heater core 40 through communication lines, and can accurately control the two according to the instructions issued by the thermal management controller 10. The installation method of the integrated controller 20 is flexible. It can be integrally installed with the compressor pump body 30 to form a compressor assembly, or integrally installed with the heater core 40 to form a heater assembly. This design not only improves the system integration degree, but also improves the space utilization rate and production assembly efficiency of the whole vehicle, providing strong support for the lightweight and high-efficiency development of new energy vehicles. The following embodiments will be described by taking the integrated controller 20 and the compressor pump body 30 as an example of integral installation to form a compressor assembly.

The first low-voltage connector 23 is responsible for connecting the thermal management controller 10, the low-voltage power supply, the ground wire, and the heater core 40 to build a communication bridge between the system and the vehicle's electrical network and other key components, ensuring the accurate transmission of control signals and the real-time feedback of the working state, enabling each component to work together and maintaining the stable operation of the thermal management system.

[0035] Please refer to Figure 1 As shown in the figure, in this embodiment, the first high-voltage connector 21 is 2-pin, which are HV+ and HV- respectively, and are connected to the positive and negative high voltages of the vehicle respectively to achieve high-voltage power supply; the second high-voltage connector 22 is 2-pin, which are HV+ and HV- respectively, and are connected to the HV+ and HV- pins of the third high-voltage connector 41 on the heater core 40 respectively to achieve high-voltage power supply for the heater; the first low-voltage connector 23 is 5-pin, which are 12V power supply, GND, control line pin, first core temperature detection pin, and second core temperature detection pin respectively.

[0036] A third high-voltage connector 41 and a second low-voltage connector 42 are provided on the heater core 40. Among them, the third high-voltage connector 41 is 2-pin, which are HV+ and HV- respectively, and are used to connect to the second high-voltage connector 22 of the compressor respectively to achieve high-voltage power supply for the core; the second low-voltage connector 42 is 2-pin, which are the first core temperature detection pin and the second core temperature detection pin respectively, and are used to connect to the first core temperature detection pin and the second core temperature detection pin of the first low-voltage connector 23 of the compressor to achieve feedback of the core temperature.

With this design, the integrated controller 20 can obtain the temperature data of the heater core 40 in real time, and accurately control the heater based on this data to ensure its stable operation within a safe temperature range, effectively preventing failures caused by abnormal temperatures, such as overheating damage. At the same time, the temperature data feedback can also help the thermal management controller optimize the thermal management strategy, improve the vehicle's thermal management efficiency, and enhance the driving comfort. In this embodiment, the integrated control module 20 is further configured to: receive the temperature T of the heater core detected through the first core temperature detection interface and the second core temperature detection interface; when T|>ΔT threshold, trigger over-temperature protection and report a fault. This mechanism ensures the accuracy and reliability of temperature monitoring, provides accurate data for the thermal management controller, helps optimize the thermal management strategy, improves the vehicle's thermal management efficiency, and enhances the driving comfort.

[0038] It can be understood that, in this embodiment, the heater core 40 is only connected to the second high-voltage connector 41 through two high-voltage lines, and is connected to the first core temperature detection interface and the second core temperature detection interface through two temperature detection lines. This system realizes the efficient integrated control of the compressor and the heater through an innovative integrated controller design and an optimized high- and low-voltage circuit connection method, reduces the number of controllers and wire harness connections, and lowers the hardware cost and system complexity.

[0040] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the thermal management controller 10 sends a control signal to the integrated controller 20 through the bus according to the real-time thermal load demand of the vehicle. The integrated controller 20 receives the control signal of the thermal management controller 10, controls the compressor pump body 30 to operate according to the target through the internal circuit. The integrated controller 20 accurately regulates the operating state of the compressor pump body 30 accordingly, and feeds back the working state and fault state information to the thermal management controller 10 through the bus pin, ensuring the efficient and reliable operation of the thermal management system, and improving the thermal management efficiency and safety of the vehicle. The control signals include but not limited to:

[0049] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the thermal management controller 10 sends a control signal to the integrated controller 20 via the bus according to the real-time thermal load demand of the vehicle. The integrated controller 20 receives the control signal from the thermal management controller 10, controls the heater core 40 to operate according to the target through this control signal, accurately regulates the operating state of the heater core 40 by the integrated controller 20, and feeds back the operating status and fault status information of the heater core 40 to the thermal management controller 10 via the bus pin, ensuring the efficient and reliable operation of the thermal management system and improving the thermal management efficiency and safety of the vehicle.

[0058] Heater serial number: Feed back the compressor serial number information;

[0059] Heater part number: Feed back the compressor part number information.

[0060] Please refer to Figure 1 As shown, in this embodiment, a high-voltage interlock module is integrated in the integrated controller 20. This module ensures the safety of high-voltage power supply by monitoring the voltage and current of the high-voltage circuit. Specifically, the high-voltage interlock module is configured to: Real-time monitor the output voltage and output current of the first high-voltage connector and / or the second high-voltage connector, and feed them back to the thermal management controller through the bus; When it is detected that the voltage or current of any one of the first high-voltage connector and the second high-voltage connector is not within the preset range, the thermal management controller controls to cut off the high-voltage power supply.

[0061] In this embodiment, when abnormal voltage or current is detected, the thermal management controller responds quickly, promptly disconnects the high-voltage power supply circuit, prevents the expansion of faults, protects key components such as the compressor and heater in the thermal management system from damage, and improves the safety and reliability of the entire thermal management system. For example, the high-voltage interlock module includes a voltage sampling circuit for collecting the output voltage and a current sampling circuit for collecting the output current, and feeds back to the thermal management controller through a bus. The thermal management controller controls whether to disconnect the high-voltage power supply according to the voltage and current. The voltage sampling circuit is connected to the HV+ and HV- pins in the first high-voltage connector and / or the second high-voltage connector, and is used to monitor the voltage level in the high-voltage circuit in real time to ensure that the voltage is within a safe range; the current sampling circuit is connected to the HV+ and HV- pins in the first high-voltage connector and / or the second high-voltage connector, and is used to monitor the current in the high-voltage circuit in real time to ensure that the current is within the rated range and prevent overload or short-circuit conditions. The high-voltage interlock module composed of these two circuits enables the system to monitor the operating state of the high-voltage circuit in real time. When the monitored voltage or current is not within the preset range, the protection mechanism will be triggered, and the thermal management controller will promptly control the disconnection of the high-voltage power supply circuit, thereby effectively protecting key components such as the compressor and heater in the thermal management system from damage and ensuring the safety and reliability of the entire thermal management system. Of course, a current sensor can also be used to collect current, and this current sensor can directly reuse the existing current sensor in the system.

[0062] In this embodiment, the high-voltage interlock module in the integrated controller 20 adopts the methods of voltage detection and current detection, and can monitor the voltage and current conditions in the high-voltage circuit in real time. When the high-voltage interlock module detects abnormal voltage or current, such as the situation where the voltage or current is not within the preset range and may endanger the system safety, the thermal management controller will quickly respond, trigger the disconnection mechanism of the high-voltage power supply, and promptly cut off the high-voltage power supply, thereby achieving effective protection of the high-voltage system, preventing faults or safety accidents caused by high-voltage abnormalities, and ensuring the safe operation of the thermal management system and the whole vehicle. For example, the detection process is as follows:

[0063] Collect voltage and current;

[0064] Judge whether the voltage is normal;

[0065] If the voltage is not normal, control to cut off the high-voltage power supply and report the fault;

[0066] If the voltage is normal, judge whether the current is normal;

[0067] If the current is normal, work normally;

[0068] If the current is not normal, control to cut off the high-voltage power supply and report the fault.

[0069] It can be understood that the traditional high-voltage interlock loop contains multiple potential failure points. For example, failures may occur in 4 connectors and two wire harnesses. In this embodiment, the software high-voltage interlock function is applied to replace the traditional hard-wired high-voltage interlock, and there is no dedicated interlock circuit, which further simplifies the system structure and enhances the reliability and safety of the system.

[0070] Please refer to Figure 1 As shown, in this embodiment, the integrated controller 20 is built with a fault diagnosis module, which has the ability to monitor the operating status of the compressor and heater in real time and diagnose faults. Once various faults occur in the compressor or heater, such as storage faults, communication loss, overcurrent faults, high-voltage overvoltage faults, high-voltage undervoltage faults, IGBT open-circuit faults, IGBT short-circuit faults, overload faults, RAM faults, ROM faults, etc., the fault diagnosis module can quickly and accurately diagnose the fault type and promptly feedback the detailed fault information to the thermal management controller. After receiving the fault information, the thermal management controller will take corresponding measures for fault handling and repair according to the severity and type of the fault, such as reducing the power of the compressor or heater, starting the standby mode or reminding the driver to perform maintenance, etc., so as to effectively reduce the impact of the fault on the vehicle operation, improve the overall reliability and safety of the system, and ensure the stable driving of the vehicle.

[0071] Please refer to Figure 1 As shown, in this embodiment, efficient information interaction is carried out between the thermal management controller 10 and the integrated controller 20 through the bus. The bus includes various types such as LIN (Local Interconnect Network), CAN (Controller Area Network), and CANFD (CAN with Flexible Data-rate). The LIN bus is suitable for scenarios with relatively low transmission rate requirements and has the characteristics of low cost and simple structure; the CAN bus has a relatively high transmission rate and reliability and can meet general real-time requirements; while the CANFD bus further improves the data transmission rate and bandwidth on the basis of CAN and is suitable for application scenarios with extremely high real-time requirements. By selecting different types of buses, the system of the present invention can flexibly adapt to the diverse communication requirements and different thermal management control strategies in new energy vehicles, ensure fast, stable and reliable information interaction between the thermal management controller and the integrated controller, and thus guarantee the efficient operation of the entire thermal management system. The thermal management controller 10 sends various control signals to the integrated controller 20 via the bus according to the actual thermal load condition of the vehicle. The integrated controller 20 accurately regulates the operating status of the compressor pump body 30 and the heater core 40 according to the received signals, and real-time feedbacks the working status and fault information via the bus pins to form an efficient closed-loop control, further improving the thermal management efficiency and safety of the vehicle.

[0072] Please refer to Figure 1 As shown, in this embodiment, the integrated controller establishes a stable connection with the compressor pump body and the heater core through hard wires, achieving direct control and status monitoring of both. Specifically, the integrated controller receives the target operation instructions from the thermal management controller, and precisely regulates parameters such as the rotational speed and power of the compressor pump body, and the operating power of the heater core via hard wires, ensuring that both operate stably according to the predetermined targets. At the same time, the integrated controller is also responsible for real-time collecting the working status data of the compressor pump body and the heater core, including but not limited to operating parameters such as the current power, high-voltage voltage, low-voltage voltage, actual rotational speed, actual operating current, and various fault status information, such as overcurrent, over-temperature, IGBT fault, etc., and timely feedbacks this data to the thermal management controller, providing comprehensive and accurate system operation information for the thermal management controller, so that it can dynamically adjust the control strategy according to the actual operating conditions, optimize the working status of the thermal management system, improve the energy efficiency and driving comfort of the vehicle, and ensure the efficient and stable operation of the vehicle thermal management system.

[0073] It can be understood that the thermal management controller 10 includes but is not limited to a separate thermal management controller, a domain controller integrating thermal management control functions, etc. The heater types include water heaters, air heaters, etc. The heater technical solutions include PTC heaters, thin-film heaters, etc.

[0074] The present invention also proposes a vehicle, which includes the compressor and heater control integration system described in the above embodiment. To avoid repetition, it will not be elaborated here.

[0075] The compressor and heater control integration system of the present invention can be widely applied to various new energy vehicles. In actual applications, through the innovative integrated controller design and optimized high- and low-voltage circuit connection methods, the system realizes the efficient integrated control of the compressor and the heater, reduces the number of controllers and wire harness connections, and lowers the hardware cost and system complexity. The application of the software high-voltage interlock function further simplifies the system structure and enhances the reliability and safety of the system. The design of the core temperature detection line realizes the real-time monitoring of the working status of the heater, ensuring that the heater operates within a safe range. In addition, the efficient information interaction between the integrated controller and the thermal management controller enables the thermal management system to flexibly adjust the thermal management strategy according to the actual needs of the vehicle, optimize the working status of the thermal management system, improve the energy efficiency and driving comfort of the vehicle. By applying the thermal management system of the present invention in the vehicle, the thermal management performance and integration degree of the vehicle can be effectively improved, meeting the requirements of new energy vehicles for high-performance, high-integration and low-cost thermal management systems, and promoting the development of the new energy vehicle industry.
