[0031] Figure 2 is another structural diagram of a seat control device provided by the present disclosure. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following makes an explanation of the exemplary embodiments of the present application with reference to the drawings, including various details of the embodiments of the present application to facilitate understanding. It should be considered that they are only exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted below.

[0033] Please refer to Figure 1 , Figure 1 is a structural diagram of a seat control device provided by the present disclosure, as shown in Figure 1As shown in the figure, the seat control device includes: a seat controller 10, a body domain controller 20, a target key device 30, and an in-vehicle infotainment system 40;

[0034] The first output end of the seat controller 10 is connected to the first input end of the body domain controller 20 through a Local Interconnect Network (LIN) bus;

[0035] The first output end of the body domain controller 20 is connected to the first input end of the seat controller 10 through the LIN bus. The second output end of the body domain controller 20 is connected to the first input end of the target key device 30 through a Controller Area Network (CAN) bus. The third output end of the body domain controller 20 is connected to the first input end of the in-vehicle infotainment system 40 through the CAN bus;

[0036] The first output end of the target key device 30 is connected to the second input end of the body domain controller 20 through the CAN bus;

[0037] The first output end of the in-vehicle infotainment system 40 is connected to the third input end of the body domain controller 20 through the CAN bus.

[0038] In the solution of the present utility model, there are multiple control methods for setting the state of the vehicle seat. First, the body domain controller 20 and the seat controller 10 are bidirectionally connected through the LIN bus, and the target key device 30 and the body domain controller 20 are bidirectionally connected through the CAN bus. Therefore, the user can control the seat controller 10 by operating the target key device 30. Similarly, the in-vehicle infotainment system 40 is also bidirectionally connected to the body domain controller 20 through the CAN bus. Therefore, the user can also control the seat controller 10 by controlling the in-vehicle infotainment system 40. Through the setting of this structure, the convenience and intelligent control requirements of the user for adjusting the vehicle seat are met. In addition, through the method of communication message transmission by the body domain controller 20, when adding control methods for the vehicle seat, only the software of the body domain controller 20 needs to be upgraded. After receiving the new control instruction, it is converted into the same LIN message information and sent to the seat controller 10, which can ensure the generalization of the hardware and software in the seat control device, thereby improving the convenience of the seat control device.

[0039] Among them, the target key device 30 can include various modes or intensity levels for the user to choose from. For example, the target key device 30 can include buttons corresponding to eight sports modes, and buttons corresponding to three intensities (high intensity, medium intensity, and low intensity). Of course, the virtual buttons on the in-vehicle infotainment system 40 can also correspond one-to-one to the buttons included in the target key device 30.

[0040] It should be noted that for the convenience of users to control the vehicle seat, an indicator light can be set on the buttons of the target key controller 30, that is, when the indicator light is on, it means that the vehicle seat is in the working state, and when the indicator light is off, it means that the vehicle seat is in the non-working state.

[0041] For the convenience of understanding, the following is an example of the process for the user to operate the above seat control device:

[0042] 1) The user operates the target key controller 30, and the target key controller 30 sends the message of the selected mode or intensity gear through the CAN bus to the body domain controller 20.

[0043] 2) The body domain controller 20 converts the CAN message into a corresponding LIN message and sends it to the seat controller 10.

[0044] 3) The seat controller 10 performs seat adjustment control according to the received LIN message and feeds back the executed mode or gear intensity LIN message to the body domain controller 20.

[0045] 4) The body domain controller 20 converts the received LIN message into a corresponding CAN message and synchronously sends it to the target key controller 30 and the in-vehicle infotainment system 40.

[0046] 5) The target key controller 30 lights up the corresponding indicator light according to the received CAN message, and the in-vehicle infotainment system 40 can light up the corresponding virtual button according to the received CAN message.

[0047] 6) When the user operates the physical switch of the target key controller 30 to turn off the massage function of the vehicle seat, the message of the off command is transmitted according to steps 1) to 5) until the display light of the target key controller 30 and the virtual button light of the in-vehicle infotainment system 40 go out.

[0048] Optionally, please refer to Figure 2 , Figure 2 which is another structural diagram of a seat control device provided by the present disclosure. The device further includes: a voice controller 50;

[0049] The first output end of the voice controller 50 is connected to the fourth input end of the body domain controller 20 through the CAN bus, and the first input end of the voice controller 50 is connected to the fourth output end of the body domain controller 20 through the CAN bus.

[0050] In this embodiment, the voice controller 50 and the body domain controller 20 are bidirectionally connected via the CAN bus. Therefore, the user can describe the required mode or intensity level for the vehicle seat by voice. The voice controller 50 recognizes it and converts it into a specified message and transmits it to the body domain controller 20. The body domain controller 20 converts the CAN message into a corresponding LIN message and sends it to the seat controller 10, thereby realizing the seat massage function. Of course, when the user turns off the massage function of the vehicle seat by voice, it is also controlled by message transmission. By this method, it provides convenience for the user in controlling the vehicle seat and further improves the safety of the driver during driving.

[0051] Optionally, the device further includes: a sensor;

[0052] The sensor is disposed at a first position of the vehicle seat. The first output end of the sensor is connected to the fifth input end of the body domain controller 20 via the CAN bus, and the first input end of the sensor is connected to the fifth output end of the body domain controller 20 via the CAN bus;

[0053] Wherein, the sensor is used to detect the speed information of the vehicle and transmit it to the body domain controller 20.

[0054] In this embodiment, by setting the above sensor to obtain the driving state of the user. For example, when the vehicle is accelerating, the above sensor can detect the vehicle acceleration, thereby transmitting a signal message to the body domain controller 20, and then controlling the seat controller 10, that is, controlling the lumbar support motor of the seat to work and straightening the backrest, thereby improving the convenience of the seat control device.
