[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the accompanying drawings show exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0037] First, let’s explain the terms used in this application:

[0038] Core board: A circuit board that integrates a microprocessor, memory and some necessary interface circuits to realize computing and control functions.

[0039] Telematics Box (T-BOX): An in-vehicle communication module used to connect the vehicle to external networks. It typically includes components such as a GPS positioning system, a wireless communication interface, and a microcontroller. It monitors the vehicle's operating status in real time and exchanges data with other devices.

[0040] The Body Control Module (BCM) is an electronic control unit (ECU) that controls the vehicle's electrical systems and is a crucial component of the vehicle. The BCM's primary functions include controlling power windows, power mirrors, air conditioning, headlights, turn signals, anti-theft locking system, central locking, and defrost.

[0041] With the development of technology, users can use software on their mobile phones to remotely control some functions in the vehicle, such as turning on the air conditioner. Remote control of the vehicle is inseparable from the communication interaction between the T-BOX module and the BCM.

[0042] Currently, the T-BOX module and the BCM are usually set up separately and connected through a Controller Area Network (CAN) bus, resulting in a long communication link and low data transmission efficiency.

[0043] In view of this, an embodiment of the present invention provides a vehicle body domain controller, which connects the T-BOX module and the BCM board-to-board to form an integrated domain controller, thereby shortening the communication distance and improving the transmission efficiency. At the same time, the T-BOX module is no longer required to be set up separately, saving manufacturing costs.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0046] Figure 1 FIG. 1 shows a schematic structural diagram of a first embodiment of a vehicle body domain controller provided by the present invention; FIG. Figure 1 As shown, the vehicle body domain controller 100 provided by the present invention includes a T-BOX core board 101 and a vehicle body control core board 102 .

[0047] The T-BOX core board 101 is provided with a first board-to-board (BTB) connector 103 , and the body control core board 102 is provided with a second BTB connector 104 . The first BTB connector 103 is connected to the second BTB connector 104 .

[0048] By way of example, the T-BOX core board 101 represents the core board of a T-BOX module. The T-BOX core board may include components such as a memory, a microcontroller, a positioning antenna, and a communication module. The present invention does not limit the components included in the T-BOX core board. The T-BOX core board 101 is used to enable communication between the vehicle and an external network.

[0049] The body control core board 102 is a core board in the BCM. The body control core board may include components such as a microcontroller and a memory. The present invention does not limit the components included in the body control core board. The body control core board 102 is used to control the vehicle.

[0050] The first and second BTB connectors described above represent board-to-board connectors. The connection between the first and second BTB connectors represents the connection of two BTB connectors. In one possible implementation, the first BTB connector can function as a male connector, and the second BTB connector can function as a female connector. The first and second BTB connectors can be connected together by plugging, snapping, or magnetically connecting. It should be noted that the present invention does not limit how the first and second BTB connectors are connected.

[0051] In some possible implementations, the first BTB connector and the second BTB connector include a communication interface, which is connected together by the first BTB connector and the second BTB connector. The communication interfaces in the two connectors are turned on, and communication between the T-BOX core board and the body control core board can be achieved based on the first BTB connector and the second BTB connector.

[0052] For example, refer to Figure 2 As shown, Figure 2 A schematic diagram of a first BTB connector and a second BTB connector provided by the utility model is shown. The T-BOX core board may include at least one first communication interface; wherein the first communication interface may, for example, include one or more of the following: a serial peripheral interface (SPI), an integrated circuit bus interface (IIC), a general-purpose input / output interface (GPIO), and an Ethernet interface. It should be noted that the Ethernet interface may, for example, be a network port of a network card. The first communication interface is connected to the first BTB connector, for example, the pins of the first communication interface may be set on the first BTB connector to realize the connection between the first communication interface and the first BTB connector. It should be noted that, Figure 2 The example in which the first communication interface includes an SPI, a GPIO interface, and an Ethernet interface is used for illustration only.

[0053] refer to Figure 2As shown, the body control core board may include at least one second communication interface; wherein the second communication interface may, for example, include one or more of the following: Serial Peripheral Interface (SPI), Integrated Circuit Bus Interface (IIC), General-purpose input / output Interface (GPIO), Ethernet gateway interface. It should be noted that the Ethernet gateway interface may be, for example, a port of a gateway. The second communication interface is connected to the second BTB connector, for example, the pins of the second communication interface may be set on the second BTB connector to realize the connection between the second communication interface and the second BTB connector. It should be noted that, Figure 2 The second communication interface includes an SPI, a GPIO interface, and an Ethernet gateway interface as an example for illustration.

[0054] It should be noted that the communication interfaces in the BTB connector are set correspondingly. In other words, when the first BTB connector is connected to the second BTB connector, the communication interfaces in the BTB connector can be connected correspondingly. For example, the SPI interface in the first BTB connector is connected correspondingly to the SPI interface in the second BTB connector, and the Ethernet interface in the first BTB connector is connected correspondingly to the Ethernet gateway interface in the second BTB connector.

[0055] It should be noted that the present embodiment does not limit the type of communication interface included in the BTB connector, and it can be set according to actual needs. It should be understood that the present embodiment does not limit which communication interface is used to transmit data between the T-BOX core board and the vehicle body control core board quality inspection, and it is specifically related to the type of data transmitted.

[0056] In this way, the T-BOX core board and the body control core board are integrated into a body domain controller using the first BTB connector and the second BTB connector. This not only enables communication between the vehicle and the external network and control of the vehicle through the first BTB connector and the second BTB connector, shortening the communication link, but also saves costs such as the cost of setting up a separate T-BOX module shell.

[0057] In some possible implementations, the transmission of electrical signals can be achieved by connecting the first BTB connector and the second BTB connector. Therefore, after the vehicle is powered on, the body control core board can power the T-BOX core board based on the first BTB connector and the second BTB connector, eliminating the need to set up an additional power supply circuit between the vehicle power supply and the T-BOX core board, thereby saving vehicle costs.

[0058] In this embodiment, a T-BOX core board provided with a first BTB connector and a body control core board provided with a second BTB connector are physically connected with the body control core board using the first BTB connector and the second BTB connector, and integrated into a body domain controller. The T-BOX core board can communicate with the body control core board through the first BTB connector and the second BTB connector, without the need to use the CAN bus for communication, thereby shortening the communication link and improving the transmission efficiency. Moreover, the T-BOX core board and the body control core board are integrated into a body domain controller, without the need to set up a T-BOX module separately, thereby reducing the manufacturing cost.

[0059] Figure 3 FIG. 1 shows a schematic structural diagram of a second embodiment of a vehicle body domain controller provided by the present invention; FIG. Figure 3 As shown, the body domain controller 100 provided by the present invention includes a T-BOX core board 101, a body control core board 102 and a microcontroller unit (MCU) 106; the above-mentioned microcontroller 106 is arranged on the body control core board 102, and the T-BOX core board 101 and the body control core board 102 share the microcontroller 106.

[0060] The microcontroller 106 is connected to the second BTB connector 104 based on the second communication interface. Figure 3 As shown, the microcontroller 106 can be directly connected to the SPI interface and GPIO interface in the second BTB connector 104 through the SPI bus and GPIO bus respectively, and connected to the Ethernet gateway interface in the second BTB connector 104 through the port connected to the Ethernet gateway.

[0061] The microcontroller 106 may be a multi-core MCU. The embodiment of the present invention does not limit the number of cores of the MCU, and the number may be set according to actual needs. The MCU may be used to process the received data to obtain corresponding processing results.

[0062] For example, there is no need to set up a microcontroller on the T-BOX core board, and the same microcontroller 106 can be used together with the body control core board. The microcontroller can not only execute the communication-related processing logic from the T-BOX core board, but also execute the body control-related processing logic from the body control core board, such as lighting control, door lock control, air conditioning control, etc.

[0063] In this way, the body control core board and the T-BOX core board can share the same MCU, and the processing logic of the T-BOX core board can be executed by the MCU of the body control core board. There is no need to set up an MCU in the T-BOX core board, which saves the number of MCUs and thus saves manufacturing costs.

[0064] In this embodiment, a T-BOX core board provided with a first BTB connector and a body control core board provided with a second BTB connector are physically connected by using the first BTB connector and the second BTB connector. After being integrated into a body domain controller, the communication distance is shortened and the control logic of the T-BOX core board can be implemented by using the microcontroller of the body control core board. There is no need to set a microcontroller on the T-BOX core board, which reduces the number of microcontrollers and saves manufacturing costs.

The above-mentioned SoC chip is used to process data so that it can be sent to an external network or to a body control core board.

[0068] The antenna module 107 may include a communication antenna and a positioning antenna. The type of communication antenna corresponds to the type of mobile communication chip in the communication module. This antenna module is used to forward data. The antenna in the antenna module can be located anywhere in the vehicle and only needs to be connected to the communication module.

[0069] The memory 108 is used to store data required by the SoC chip. The memory can be a non-volatile memory, such as flash memory, one-time programmable (OTP) memory, electrically erasable programmable read-only memory (EEPROM), or an embedded multi-media card (EMMC). It should be noted that the embodiment of the present invention does not limit the type and capacity of the memory.

[0070] The above-mentioned user identity card 109 is used to provide mobile communication network services for the vehicle body domain controller. The user identity card can be a traditional user identity card (Subscriber Identity Module, SIM card), which needs to be inserted into the card slot of the device for use; it can also be an embedded SIM card (embedded-Subscriber Identity Module, eSIM card), which is an electronic version of the SIM card. It can be directly integrated into the device and does not need to be inserted into the card slot of the device like a traditional SIM card.

[0071] The backup battery 111 is used to power the T-BOX core board when the vehicle is not powered on. It should be noted that the embodiment of the present invention does not limit the type of the backup battery, for example, it can be a lithium battery or a supercapacitor. Optionally, the backup battery can be integrated into the T-BOX core board or located elsewhere in the vehicle, which is not limited in the embodiment of the present invention. Figure 4 The backup battery is shown as being located elsewhere on the vehicle.

[0072] The battery management module 110 is used to manage the backup battery of the T-BOX core board. This battery management module may include, for example, a controller, temperature sensor, and voltage sensor to ensure the safety and lifespan of the backup battery. It should be noted that this utility model does not limit the structure of the battery management module; it can be configured based on actual needs.

[0073] The audio input and output module 112 may include, for example, a microphone, a speaker, an encoder, and a decoder. The audio input and output module is used to decode the received audio information and encode the output audio information. It should be noted that the microphone, speaker, and other devices in the audio input and output module may be located in the vehicle's cabin, and the encoder and decoder may be integrated into the T-BOX core board.

[0074] In some possible implementations, reference Figure 4 As shown, the above-mentioned body control core board 102 can also include at least one controller area network CAN bus transceiver 115, and the CAN bus transceiver 115 is connected to the microcontroller 106 and the body function module 116 respectively. The body control core board 102 and the body function module 116 share the microcontroller 106.

[0075] The above-mentioned body function module 116 represents a module that controls the behavior function of the body, for example, it can be a seat function module, a window function module, a tailgate function module, a rear wing function module, a side step function module, an electric sliding door function module, etc., and can be specifically set according to actual needs.

[0076] The CAN bus transceiver 115 is an electronic component used for CAN bus communication, which can realize the conversion between digital signals and differential signals transmitted on the CAN bus so that the signals can be processed by the MCU, or the signals can be transmitted on the CAN bus.

[0077] The microcontroller 106 can not only execute the processing logic related to the body control from the body control core board, but also execute the processing logic corresponding to the body functional modules, such as seat control, tailgate control, etc.

[0078] In this way, the body domain controller can realize that the body function module and the body control core board share the same microcontroller based on the CAN bus. The processing logic of the body function module can be executed by the microcontroller of the body control core board. There is no need to set up a microcontroller in the body function module. The body function module only needs to execute the corresponding driving logic based on the processing results returned by the microcontroller, which saves the number of microcontrollers and thus saves manufacturing costs.

[0079] In some possible implementations, reference Figure 4 As shown, the body control core board 102 may further include an Ethernet gateway 113 , a network connector 114 and at least one CAN bus transceiver 115 .

[0080] The Ethernet gateway is connected to the microcontroller and the network connector respectively; the CAN bus transceiver is connected to the microcontroller and the network connector respectively; wherein the network connector is connected to at least one type of communication line.

[0081] The Ethernet gateway 113 is used to realize data transmission between different networks inside the vehicle and ensure mutual communication between various control units.

[0082] The network connector 114 is used to connect various types of communication lines, allowing different types of communication lines to be connected to the Ethernet gateway. Examples of communication lines include 100Base-T1, 1000Base-T1, local area network (LIN) bus, and CAN bus, but are not limited in this embodiment of the present invention.

[0083] In this way, the T-BOX core board can be connected to the Ethernet gateway through the internal communication interface (Ethernet interface) in the BTB connector without the need for CAN bus communication, further shortening the communication link between the T-BOX core board and the Ethernet gateway and improving transmission efficiency.

[0084] Optionally, the vehicle body control core board may further include a GPIO interface, which is connected to a network connector for communicating with the vehicle body functional module.

[0085] Figure 5 The structure diagram of the fourth embodiment of the vehicle body domain controller provided by the present utility model is shown; Figure 5 As shown, the body domain controller also includes a body function module 116; a third BTB connector 117 is provided on the body function module 116, and a fourth BTB connector 118 is provided on the body control core board 102.

The connection between the fourth and third BTB connectors is similar to the connection between the first and second BTB connectors described above and will not be further described here.

[0087] The above-mentioned microcontroller can not only execute the processing logic related to body control from the body control core board, but also execute the processing logic corresponding to the body functional modules, such as seat control, tailgate control, etc.

The processing logic of the body function module can be executed by the microcontroller of the body control core board. There is no need to set up a microcontroller in the body function module.
