Background Art

[0002] With the rapid development of the new energy vehicle industry, pure electric control systems are being used more and more widely in the automotive industry, and the functions and demands of vehicles are increasing. As an indispensable part, electric compressors and heaters also occupy a relatively important position in the body layout.

[0003] However, at present, most electric compressors and heaters of electric vehicles adopt a split design, and the compressor and heater have their own controller cabin, controller, high and low voltage connectors and controller cover, which makes the wiring harness and components redundant, and the system integration is not high, which increases the hardware cost. In terms of vehicle layout, the increase in wiring harness length and complexity will also lead to a more dispersed vehicle layout. Summary of the invention

[0004] In view of this, the present invention aims to propose an integrated control system of a compressor and a heater, so as to improve the integration height of the thermal system and reduce the hardware cost.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An integrated control system for a compressor and a heater includes a control assembly, wherein the control assembly includes a first controller and a second controller;

[0007] A high-voltage power connector and a low-voltage power connector are integrated on the first controller, and a high-voltage wiring harness and a low-voltage wiring harness are connected between the first controller and the second controller;

[0008] A first insulated gate bipolar transistor drive circuit is integrated on the first controller, and the first insulated gate bipolar transistor drive circuit is connected to one of the compressor and the heater;

[0009] A second insulated gate bipolar transistor drive circuit is integrated on the second controller, and the second insulated gate bipolar transistor drive circuit is connected to the other of the compressor and the heater.

[0010] Furthermore, a first microcontroller unit, a first watchdog, a first clock module and a first analog-to-digital converter are integrated on the first controller; and a first wiring harness for transmitting a second insulated gate bipolar transistor drive signal is connected between the first controller and the second controller.

[0011] Furthermore, a second wiring harness for transmitting a second insulated gate bipolar transistor temperature signal is connected between the first controller and the second controller; and / or a third wiring harness for transmitting a second insulated gate bipolar transistor current signal is connected between the first controller and the second controller.

[0012] Furthermore, a first CAN transceiver and / or a first LIN transceiver is integrated on the first controller.

[0014] Furthermore, a first CAN transceiver is integrated on the first controller, and a second CAN transceiver is integrated on the second controller; a CAN bus connector is integrated on the first controller, and a fourth wiring harness for transmitting CAN signals is connected between the first controller and the second controller.

This can help improve the integration level of the compressor and the heater, reduce the number of connectors and wiring harnesses used, reduce hardware costs, and also help optimize the wiring harness layout.

[0020] In addition, the first wiring harness connected between the first controller and the second controller is used to transmit a driving signal, and the driving instruction is transmitted to the second insulated gate bipolar transistor driving circuit on the second controller through the first wiring harness, so that the setting of the MCU in the second controller can be reduced. The second wiring harness provided can be conducive to feeding back the temperature information of the second controller to the first micro control unit, and the third wiring harness provided can be conducive to feeding back the current information of the second controller to the first micro control unit, so that the first controller and the second controller can further improve the degree of system integration, reduce the number of hardware, and reduce hardware costs by sharing the first micro control unit.

A fifth wiring harness is provided between the first controller and the second controller, and the first controller and the second controller can share a LIN bus connector, thereby reducing the number of LIN bus connectors used.

[0023] In addition, the two sides of the controller housing are respectively connected to the compressor housing and the heater housing, so that the compressor and the heater housing are connected and share a control component accommodating space. On the one hand, the number of controller covers can be reduced and the hardware weight can be reduced.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] Embodiment 1

[0048] This embodiment relates to an integrated control system of a compressor and a heater, which can improve the integration height of a thermal system and reduce hardware costs.

[0049] In terms of overall composition, Figure 1and Figure 2 As shown, the integrated control system of the compressor and the heater of this embodiment mainly includes a control component, which includes a first controller 10 and a second controller 20. Among them, the first controller 10 is integrated with a high-voltage power connector 1 and a low-voltage power connector 2, and a high-voltage wiring harness 11 and a low-voltage wiring harness 12 are connected between the first controller 10 and the second controller 20. The first controller 10 is integrated with a first insulated gate bipolar transistor drive circuit 101, and the first insulated gate bipolar transistor drive circuit 101 is connected to one of the compressor and the heater. The second controller 20 is integrated with a second insulated gate bipolar transistor drive circuit 201, and the second insulated gate bipolar transistor drive circuit 201 is connected to the other of the compressor and the heater.

[0050] In such a structure, by making the first controller 10 and the second controller 20 share a set of high-voltage power connectors 1 and low-voltage power connectors 2, as well as a set of high-voltage wiring harnesses 11 and low-voltage wiring harnesses 12, and one of the first controller 10 and the second controller 20 is a compressor controller, and the other is a heater controller, it is beneficial to improve the integration level of the compressor and the heater, reduce the use of connectors and wiring harnesses, reduce hardware costs, and also help optimize the wiring harness layout.

[0051] It should be noted that Figure 1 and Figure 2 The following are two exemplary schematic diagrams designed based on the above design ideas. Figure 1 and Figure 2 In the figure, a first insulated gate bipolar transistor driving circuit 101 integrated on a first controller 10 is connected to a first control object 100, and a second insulated gate bipolar transistor driving circuit 201 integrated on a second controller 20 is connected to a second control object 200, and the first control object 100 and the second control object 200 are compressors or heaters.

[0052] It is worth pointing out that the first controlled object 100 may be a compressor, and the second controlled object 200 may be a heater. Of course, the first controlled object 100 may also be a heater, and the second controlled object 200 may be a compressor. That is, one of the first controller 10 and the second controller 20 is a compressor controller, and the other is a heater controller.

[0053] In addition, it should be noted that the MCU (Microcontroller Unit), ADC (Analog to digital converter), AC (Air-conditioning controller), PDU (Power Distribution Unit), and IGBT (Insulated Gate Bipolar Transistor) driving circuits mentioned in the following of this embodiment can all adopt existing mature technologies.

[0054] Below Figure 1 An integrated control system is described in detail in FIG. Figure 1 As shown, a high voltage power connector 1 and a low voltage power connector 2 are integrated on the first controller 10, and a high voltage wire harness 11 and a low voltage wire harness 12 are connected between the first controller 10 and the second controller 20. A first insulated gate bipolar transistor drive circuit 101 is integrated on the first controller 10, and the first insulated gate bipolar transistor drive circuit 101 is connected to the first control object 100. A second insulated gate bipolar transistor drive circuit 201 is integrated on the second controller 20, and the second insulated gate bipolar transistor drive circuit 201 is connected to the second control object 200.

[0055] Moreover, the first microcontroller unit 102, the first watchdog 103, the first clock module 104 and the first analog-to-digital converter 105 are also integrated on the first controller 10. Moreover, a first wiring harness 13 for transmitting the second insulated gate bipolar transistor drive signal is connected between the first controller 10 and the second controller 20. At this time, the drive instruction can be transmitted to the second insulated gate bipolar transistor drive circuit 201 on the second controller 20 through the first wiring harness 13, so that the setting of the MCU in the second controller 20 can be reduced.

[0056] As a preferred embodiment, a second wire harness 14 for transmitting the temperature signal of the second insulated gate bipolar transistor is also connected between the first controller 10 and the second controller 20. The second wire harness 14 can be used to feed back the temperature information of the second controller 20 to the first micro control unit 102.

[0057] As a preferred embodiment, a third wire harness 15 for transmitting the current signal of the second insulated gate bipolar transistor is also connected between the first controller 10 and the second controller 20. The third wire harness 15 is arranged to facilitate the current information of the second controller 20 to be fed back to the first micro control unit 102.

[0058] At this time, the second wiring harness 14 and the third wiring harness 15 are set at the same time, so that the first controller 10 and the second controller 20 share the first microcontroller unit 102, that is, share one MCU. This can reduce the number of MCU settings and further improve the system's integration level, reduce the amount of hardware, and reduce hardware costs.

[0059] In addition, in this embodiment, the first controller 10 is also integrated with a first CAN transceiver 106 and a first LIN transceiver 107. This can reduce the number of CAN transceivers and LIN transceivers used. The first controller 10 and the second controller 20 share a CAN transceiver and a LIN transceiver, which can further improve the integration of the system, reduce the number of hardware, and make the wiring harness layout simpler, while also further reducing the hardware cost.

[0060] It is understandable that, in addition to sharing the CAN transceiver and the LIN transceiver, the first controller 10 and the second controller 20 may also only share the CAN transceiver, or only share the LIN transceiver, which is also feasible.

[0061] like Figure 1 As shown, the first controller 10 in the dashed frame and the second controller 20 in the dotted frame are different in structure. Among them, the second controller 20 does not integrate circuit modules such as MCU, CAN transceiver, LIN transceiver, etc. This part of the circuit module is shared with the first controller 10. The respective request signals of the first controller 10 and the second controller 20 are transmitted through the low-voltage power connector 2, the CAN bus connector 3 and the LIN bus connector, and are transmitted to the communication module, namely the CAN transceiver and the LIN transceiver. According to the communication protocol identification, the respective drive circuits are controlled respectively through the shared first micro control unit 102. Similarly, the feedback signal is also sent to the upper controller through the same communication module using the CAN bus connector 3 and the LIN bus connector 4.

[0062] and, Figure 1 In the integrated control system of the compressor and the heater shown, only one low-voltage power connector 2 is provided, and the low-voltage power connector 2 is provided on the first controller 10, and the low-voltage power connector 2 is used to connect to the low-voltage power supply. The low-voltage power supply is connected to the first controller 10 through the low-voltage power connector 2, and provides low-voltage electricity to the first controller 10. One end of the low-voltage wiring harness 12 is connected to the low-voltage output port of the first controller 10, and the other end is connected to the low-voltage input port of the second controller 20, and the low-voltage electricity is provided to the second controller 20 through the low-voltage wiring harness 12.

[0063] and, Figure 1In the integrated control system of the compressor and heater shown, only one high-voltage power supply connector 1 is provided. The high-voltage power supply is connected to the first controller 10 through the high-voltage power supply connector 1 to provide high voltage electricity to the first controller 10. One end of the high-voltage wiring harness 11 is connected to the high-voltage output port of the first controller 10, and the other end is connected to the high-voltage input port of the second controller 20 to provide high voltage electricity to the second controller 20 through the high-voltage wiring harness 11.

[0064] The IGBT driving circuit on the first controller 10, i.e., the first insulated gate bipolar transistor driving circuit 101, can be directly driven by the first micro control unit 102, and the IGBT temperature and system information are also directly transmitted to the first micro control unit 102. The IGBT driving circuit on the second controller 20, i.e., the second insulated gate bipolar transistor driving circuit 201, is transmitted through the first wiring harness 13, and at the same time, the system feedback signal such as the IGBT temperature of the second controller 20 is transmitted to the first micro control unit 102 through the second wiring harness 14 and the third wiring harness 15.

[0065] Below Figure 2 An integrated control system as shown in FIG is described in detail. Figure 2 As shown, the first controller 10 and the second controller 20 are identical in structure.

[0066] The first controller 10 integrates a first micro control unit 102, a first watchdog 103, a first clock module 104 and a first analog-to-digital converter 105. Similarly, the second controller 20 integrates a second micro control unit 202, a second watchdog 203, a second clock module 204 and a second analog-to-digital converter 205.

[0067] In addition, the first controller 10 is integrated with a first CAN transceiver 106, and similarly, the second controller 20 is also integrated with a second CAN transceiver 206. The first controller 10 is integrated with a CAN bus connector 3, and a fourth wiring harness 16 for transmitting CAN signals is connected between the first controller 10 and the second controller 20. The fourth wiring harness 16 is provided for transmitting CAN signals, and enables the first controller 10 and the second controller 20 to share a CAN bus connector 3, thereby reducing the number of CAN bus connectors 3 used.

[0068] In addition, the first controller 10 is integrated with a first LIN transceiver 107, and similarly, the second controller 20 is also integrated with a second LIN transceiver 207. The first controller 10 is integrated with a LIN bus connector 4, and a fifth wiring harness 17 for transmitting LIN signals is connected between the first controller 10 and the second controller 20. At this time, the setting of the fifth wiring harness 17 enables the first controller 10 and the second controller 20 to share a LIN bus connector 4, thereby reducing the number of LIN bus connectors 4 used.

[0069] Figure 2 In the integrated control system of the compressor and the heater shown, the first controller 10 and the second controller 20 share the high voltage power connector 1, the low voltage power connector 2, the CAN bus connector and the LIN bus connector. This is also conducive to improving the integration of the compressor and the heater, reducing the number of connectors and wiring harnesses used, and reducing hardware costs.

[0070] In this embodiment, as a preferred implementation, the integrated control system of the compressor and the heater also includes a controller housing 5, in which a storage space for accommodating the control components is provided, and two sides of the controller housing 5 are respectively connected to the compressor housing 6 and the heater housing 7.

[0071] For ease of description, the structure after the compressor and the heater are integrated is referred to as a compressor heater integrated unit 300. Figure 3 As shown, the controller housing 5 can be, for example, a partial housing on the compressor and a partial housing on the heater, so that after the two partial housings are snapped together, a storage space for accommodating the control component is formed, that is, a storage space for accommodating the first controller 10 and the second controller 20.

[0072] Of course, it is understandable that the controller housing 5 can also be provided separately, and a storage space for accommodating the control components is formed in the controller housing 5. In this case, the two ends of the controller housing 5 are respectively connected to the compressor housing 6 and the heater housing 7.

[0073] In this embodiment, the compressor and the heater are designed to be integrated so that the compressor controller and the heater controller share a control component accommodation space. This can reduce the number of controller covers and the weight of the hardware on the one hand, and reduce the system volume on the other hand, while also reducing the hardware cost.

[0074] In addition, it should be mentioned that the structures not mentioned in the compressor and the heater, such as the internal components of the compressor and the internal components of the heater, can all refer to the structures in the prior art.

[0075] The integrated control system of the compressor and heater of this embodiment can improve the integration level of the compressor and the heater, reduce the number of connectors and wiring harnesses used, reduce hardware costs, and is also conducive to optimizing the wiring harness layout and has a good use effect.

[0076] Embodiment 2

[0077] The present embodiment relates to an integrated control method for a compressor and a heater, which is implemented by the integrated control system for a compressor and a heater of the first embodiment, and the control method specifically includes: the current of the high-voltage power supply is transmitted to the first controller 10 through the high-voltage power supply connector 1, and the high-voltage current of the first controller 10 is transmitted to the second controller 20 through the high-voltage wiring harness 11. The current of the low-voltage power supply is transmitted to the first controller 10 through the low-voltage power supply connector 2, and the low-voltage current of the first controller 10 is transmitted to the second controller 20 through the low-voltage wiring harness 12.

[0078] Also, the first controller 10 transmits a driving current to one of the compressor and the heater through the first insulated gate bipolar transistor driving circuit 101. The second controller 20 transmits a driving current to the other of the compressor and the heater through the second insulated gate bipolar transistor driving circuit 201.

[0079] The integrated control method of the compressor and the heater of this embodiment is conducive to optimizing the control strategy, improving the integration of the system, and reducing the hardware cost.

[0080] Embodiment 3

[0081] This embodiment relates to a vehicle, on which the integrated control system of the compressor and the heater described in the first embodiment is provided.

[0082] like Figure 4 As shown, the PDU on the vehicle is connected to the high-voltage power connector 1 on the compressor heater assembly 300 through the high-voltage wire harness 11, and the AC is connected to the low-voltage power connector 2 on the compressor heater assembly 300 through the low-voltage wire harness 12. In this way, the compressor heater assembly 300 can share a high-voltage power supply and a low-voltage power supply, which also makes the wiring harness setting outside the compressor heater assembly 300 more concise, and facilitates the improvement of the wiring harness layout.

[0083] The vehicle of this embodiment and the integrated control system of the compressor and the heater as described above have the same beneficial effects as those of the prior art.

[0084] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
