[0038] To address the shortcomings of existing technologies, this invention discloses a control system for a vehicle-mounted multi-function steering wheel, such as... Figure 1 As shown, it includes: steering wheel physical buttons 1, vehicle central control unit control module 5, vehicle central control screen display module 3, vehicle voice control module 4, and various control modules of the vehicle ECU 2.

[0039] The steering wheel physical buttons 1 are used by end users to control the steering wheel and generate control signals to send to the vehicle central control host module 5.

[0040] The vehicle central control screen display module 3 is used to support the display of the human-machine interface, as well as to obtain the operation information of the terminal user on the human-machine interface and generate control signals to send to the vehicle central control host control module 5.

[0041] The vehicle-mounted voice control module 4 is used to collect the voice of the terminal user and convert it into a voice control signal, which is then sent to the vehicle-mounted central control host module 5.

[0042] Each control module 2 of the vehicle ECU includes multiple ECU function modules, which are used to acquire and control signals from different ECU function modules.

[0043] The vehicle central control unit 5 is used to collect control signals and voice control signals from the vehicle central control screen display module 3, the vehicle voice control module 4, and the steering wheel physical buttons 1, and to control different ECU function modules according to the corresponding signal content; it is also used to run a large operating system, support the application logic of the human-machine interface, the operation of the operating system application and the voice control module 4, and coordinate the allocation, control and management of the internal hardware and software resources of the vehicle.

[0044] In some specific embodiments, the control system also includes a vehicle CAN network 6.

[0045] The vehicle CAN network 6 is mainly used to connect the vehicle's in-vehicle central control unit 5, various ECU functional modules, and steering wheel physical button 1 module, etc.

[0046] The vehicle central control unit 5 sends and receives signals to and from the vehicle ECU control modules 2 and the physical buttons on the steering wheel via the CAN network; thus enabling the vehicle central control unit 5 to collect data from the vehicle's CAN network 6 in real time.

[0047] The vehicle central control unit 5 is connected to the vehicle central control screen display module 3 via the LVDS interface and the POWER interface;

[0048] The vehicle central control unit 5 is connected to the vehicle voice control module 4 via the IIC interface and the IIS interface.

[0049] In some specific embodiments, the vehicle-mounted central control unit 5 includes a SOC system and an MCU software module.

[0050] The SOC system is used to support the normal operation of functional modules. The vehicle central control host module 5 controls each ECU functional module through the MCU software module.

[0051] Among them, the SOC system is an operating system based on SOC, and the SOC system can support UI display.

[0052] In some specific embodiments, each control module 2 of the vehicle ECU includes: an instrument control module, an air conditioning control module, a window control module, a seat control module, and a rearview mirror control module;

[0053] Each control module 2 of the vehicle ECU is used to collect instrument signals and control the windows, air conditioning, seats and adjust the rearview mirrors.

[0054] Based on the same inventive concept, embodiments of the present invention also disclose a control method for a vehicle-mounted multi-function steering wheel, such as... Figure 2 As shown, it includes:

[0055] End users control the vehicle functions through the human-machine interface, voice input and physical buttons on the steering wheel 1, and the corresponding control signals are collected to the vehicle central control host control module 5;

[0056] The vehicle central control unit 5 controls different ECU function modules within each control module 2 of the vehicle ECU according to the received control signals;

[0057] The display of the human-machine interface is supported by the vehicle central control screen display module 3, and the operation information of the human-machine interface is sent to the vehicle central control host control module 5 through the vehicle central control screen display module 3.

[0058] The voice input by the end user is converted into control signals by the voice control module 4 and sent to the vehicle central control host control module 5.

[0059] In some specific embodiments, the vehicle central control unit 5 controls different ECU functional modules within each control module 2 of the vehicle ECU according to the received operation signals, including:

[0060] Generally, after the vehicle is powered on, when the vehicle central control unit 5 is in the default mode, the SOC system has not yet started and loaded, and the SOC system application cannot receive the control operation of the steering wheel physical buttons 1.

[0061] To enable control of the vehicle's air conditioning control module in default mode, after the vehicle is powered on, the MCU software module in the vehicle's central control unit 5 collects the button control signals from the steering wheel physical buttons 1 to the air conditioning control module via the vehicle's CAN network 6, processes them, and converts them into air conditioning control signals. The vehicle's central control unit 5 then sends these air conditioning control signals to the air conditioning control module. In default mode, the air conditioning control module can be controlled directly via the steering wheel physical buttons 1, enabling default operations such as air conditioning start-up, air conditioning fan speed adjustment, and air conditioning temperature adjustment.

[0062] After the SOC system in the vehicle central control unit module 5 is powered on and the SOC-based operating system loads and runs normally, the UI control module, system applications, and voice control module 4 based on the SOC operating system can all run normally. At this time, the SOC system can be controlled through the human-machine interface or voice input to enter different control modes, such as instrument control mode, window control mode, seat control mode, and rearview mirror control mode. When the SOC system enters a different control mode, the SOC system notifies the MCU software module to enter the corresponding control module.

[0063] In different control modes, the corresponding functional modules can be controlled by operating the physical button 1 on the steering wheel:

[0064] When the SOC system in the vehicle central control unit 5 is in instrument control mode, the physical buttons 1 on the steering wheel send control signals to the instrument control module 5. The vehicle central control unit 5 converts the control signals into instrument control signals and sends them to the instrument control module to realize the control operations of the instrument control module, including page up and down, setting selection, confirmation, and resetting the trip odometer.

[0065] Based on the same principle, when the SOC system is in the window control module, operating the physical button 1 on the steering wheel can realize the control operation of the window control module, including window adjustment, sunshade adjustment, etc.

[0066] When the SOC system is in seat control mode, operating the physical button 1 on the steering wheel can control the seat control module, including adjusting the seat.

[0067] When the SOC system is in rearview mirror control mode, operating the physical button 1 on the steering wheel can control the rearview mirror control module, including adjusting the seat rearview mirror, etc.

[0068] Because the CPU processor inside the vehicle central control unit 5 has powerful functions, it can integrate various custom control functions when conditions permit; the implementation of these control functions greatly improves the convenience, fun and playability of the end user during the driving process.

[0069] Based on the same inventive concept, embodiments of the present invention also provide a vehicle, including a control system for an in-vehicle multi-function steering wheel as described above, or using the aforementioned control method for an in-vehicle multi-function steering wheel to control different ECU functional modules.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
