[0037] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0038] Traditional window control systems have evolved from manual control to electric and intelligent ones. Common power windows in cars offer enhanced convenience, and some high-end models are equipped with features like anti-pinch and automatic window closing. However, these control systems still lack support for remote control.

[0039] An embodiment of the present disclosure provides a vehicle window control system. By integrating an intelligent network controller in a cockpit domain controller, the cockpit domain controller can receive window control instructions sent from the cloud through the intelligent network controller, transmit the instructions to the body domain controller through a gateway, and the body domain controller parses the instructions into window control signals and sends them to the window actuators, thereby realizing remote control of the vehicle windows.

[0040] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 A structural block diagram of a vehicle window control system according to an embodiment of the present disclosure is shown.

[0042] According to the embodiments of the present disclosure, Figure 1 As shown, a window control system 100 is provided, characterized in that it includes: a body domain controller 110; a window actuator 111 connected to the body domain controller 110; a cockpit domain controller 120 integrated with an intelligent network controller 121; and a gateway 130 connected between the body domain controller 110 and the cockpit domain controller 120; wherein the cockpit domain controller 120 is used to receive a first window control instruction sent from the cloud through the intelligent network controller 121, and send the first window control instruction to the body domain controller 110 through the gateway 130, and the body domain controller 110 is used to send a window control signal to the window actuator 111 based on the received window control instruction, so that the window actuator 111 performs window control.

[0043] Therefore, by integrating the intelligent network controller 121 in the cockpit domain controller 120, the cockpit domain controller 120 can receive the window control instructions sent from the cloud through the intelligent network controller 212, transmit the instructions to the body domain controller 110 through the gateway 130, and the body domain controller 110 parses it into a window control signal and sends it to the window actuator 111, thereby realizing remote control of the window.

[0044] In some embodiments, the body domain controller 110 may be used to control various body functions, including but not limited to controlling vehicle lights (such as headlights, taillights, interior lights, etc.), door locks, windows, sunroofs, wipers, trunks, etc.

[0045] In some embodiments, the body domain controller 110 may be an intelligent body domain controller (IBCU).

[0046] In some embodiments, the cockpit domain controller 120 may be used to control various electronic information system functions in the vehicle's smart cockpit, such as a central control system, an in-vehicle infotainment system, an instrument system, and the like.

[0047] In some embodiments, the cockpit domain controller 120 may be an in-vehicle infotainment (IVI) system.

[0048] In some embodiments, the body domain controller 110 and the cockpit domain controller 120 may communicate through a gateway 130 .

[0049] In some embodiments, the gateway 130 may be a CAN gateway, an Ethernet gateway, or a hybrid gateway.

[0050] In some embodiments, the gateway 130 may be communicatively connected to the vehicle body domain controller 110 and the cockpit domain controller 120 via a CAN bus or an Ethernet line.

[0051] In some embodiments, the intelligent connected controller 121 integrated in the cockpit domain controller 120 can be an intelligent terminal device that integrates vehicle body network and wireless communication functions.

[0052] In some embodiments, the intelligent connected controller 121 may be a vehicle-mounted telematics terminal (Telematics Box, TBOX).

[0053] In some embodiments, the first window control instruction may be a window control instruction triggered by a user through a mobile terminal such as a mobile phone or a smart watch and transmitted to the cloud.

[0054] In some embodiments, the cockpit domain controller 120 can receive a first window control instruction transmitted from the cloud through the intelligent network controller 121, and in response to receiving the first window control instruction, send the instruction to the body domain controller 110 through the gateway 130; in response to receiving the first window control instruction from the cockpit domain controller 120, the body domain controller 110 can parse the first window control instruction, and generate a window control signal based on the window control information contained in the first window control instruction, and transmit it to the window actuator 111, so that the window actuator 111 completes the corresponding window control.

[0055] In some embodiments, there may be multiple window actuators 111 , and each window actuator corresponds to a window on the vehicle.

[0056] In some embodiments, the first window control instruction may include control instructions and control information for each window, wherein the control information may include window opening setting information, for example.

[0057] In some embodiments, the gateway in the window control system of the present disclosure may be integrated with an Ethernet switch, through which the body domain controller and the cabin domain controller communicate, thereby further improving the data transmission efficiency within the system.

[0058] In some embodiments, the vehicle body domain controller and the cockpit domain controller can be respectively connected to the gateway via Ethernet lines of any transmission rate.

[0059] In some embodiments, the vehicle body domain controller and the cockpit domain controller may be respectively connected to the gateway via Gigabit Ethernet.

[0060] In some embodiments, the vehicle body domain controller and the cockpit domain controller can each be connected to the gateway via a cable that complies with the Gigabit Ethernet standard (1000Base-T1), thereby further improving the data transmission efficiency within the system.

[0061] In some embodiments, the intelligent connected controller communicates with the cloud via a wireless network or a mobile network.

[0062] In some embodiments, the above-mentioned window control system may further include: a central control screen connected to the cockpit domain controller, wherein the cockpit domain controller is used to receive a second window control instruction from the central control screen and send the second window control instruction to the body domain controller through the gateway.

[0063] Therefore, by setting up a central control screen, users can control the car windows through the central control screen, thereby further improving the convenience of users controlling the car windows.

[0064] In some embodiments, the central control screen can be connected to the cockpit domain controller via CAN bus or Ethernet.

[0065] In some embodiments, the cockpit domain controller can be connected to the central control screen via a low-voltage differential signaling (LVDS) bus, which can further improve data transmission efficiency while reducing system power consumption.

[0066] In some embodiments, the user interface on the central control screen can provide users with a window control soft switch, for example, consisting of multiple sliders, each corresponding to a set percentage of window opening. In response to the user adjusting the opening of one or more windows using the sliders, the central control screen can send a corresponding second window control instruction to the cabin domain controller, which then transmits the instruction to the body domain controller via a gateway. In response to receiving the second window control instruction from the cabin domain controller, the body domain controller can parse the second window control instruction and generate a window control signal based on the window control information contained in the second window control instruction. The signal is then transmitted to the window actuator, causing the window actuator to complete the corresponding window control.

[0067] In some embodiments, the window control system may further include a window status sensor connected to the body domain controller. The window status sensor is configured to collect window opening information and transmit the window opening information to the body domain controller. The body domain controller is configured to transmit the window opening information to the cabin domain controller via a gateway. The cabin domain controller is configured to upload the window opening information to the cloud. Thus, by collecting window opening information through the sensor and uploading it to the cloud via the cabin domain controller, users can remotely view the current status of the windows.

[0068] In some embodiments, there may be multiple window status sensors, each corresponding to a window on the vehicle and used to collect window opening information of the corresponding window.

[0069] In some embodiments, the body domain controller can obtain the window opening information collected by each window status sensor in real time, and upload the window opening information to the cloud through the gateway and the cockpit domain controller, thereby synchronizing the window opening information to the user's mobile terminal in real time, allowing the user to remotely view the current status of the window.

[0070] In some embodiments, the vehicle body domain controller can upload the acquired window opening information to the cloud in real time. In some embodiments, after acquiring the window opening information of each window, the vehicle body domain controller can also determine whether the window opening information has changed, and in response to changes in the window opening information, upload the latest window opening information to the cloud.

[0071] In some embodiments, the cockpit domain controller can also be used to transmit window opening information to the central control screen, so that the central control screen can display the window opening information. Therefore, displaying the current window opening information on the central control screen can make the user more intuitively aware of the current state of the window, improving the user experience.

[0072] In some embodiments, the window status sensor and the window actuator may be connected to the vehicle body domain controller via hard wires, respectively.

[0073] Figure 2 A structural block diagram of a vehicle window control system according to an exemplary embodiment of the present disclosure is shown.

[0074] In some exemplary embodiments, Figure 2As shown, the window control system 200 may include: a body domain controller 210; a window actuator 211 and a window status sensor 212 connected to the body domain controller 210; a cockpit domain controller 220 integrated with an intelligent network controller 221; a central gateway 230 connected between the body domain controller 210 and the cockpit domain controller 220, and wherein the central gateway 230 is integrated with an Ethernet switch (Switch) 231; and a central control screen 240 connected to the cockpit domain controller 220 via an LVDS bus.

[0075] The vehicle body domain controller 210 is connected to the window actuator 211 and the window status sensor 212 through hard wires. The window actuator 211 is used to open and close the window, and the window status sensor 212 is used to collect window opening information.

[0076] The body domain controller 210 and the cockpit domain controller 220 can be connected to the central gateway 230 via Gigabit Ethernet.

[0077] The intelligent connected controller 221 in the cockpit domain controller 220 can communicate with the cloud via a mobile network or wireless network. The cockpit domain controller 220 can obtain window control commands transmitted from the cloud and the central control screen 240, and send these commands to the body domain controller 210 via the central gateway 230. In response to receiving the window control commands from the cockpit domain controller 220, the body domain controller 210 can parse the window control commands and generate window control signals based on the window control information contained in the window control commands. The signals are then transmitted to the window actuator 211, which then controls the windows accordingly.

[0078] The body domain controller 210 can obtain the window opening information of each window in real time through the window status sensor 212, and send the window opening information to the cockpit domain controller 220 via the gateway 230. The cockpit domain controller 220 then uploads the window opening information to the cloud via the intelligent network controller 221, so that the user can view the real-time status of the window through the mobile terminal; at the same time, the cockpit domain controller 220 sends the window opening information to the central control screen 240 via the LVDS bus, so that the central control screen 240 can display the real-time status of the window in the user interface.

[0079] In some embodiments, the vehicle body domain controller and the cockpit domain controller communicate based on the SOME / IP protocol.

[0080] In some embodiments, the body domain controller and the cockpit domain controller are respectively integrated with the SOME / IP protocol stack, wherein the SOME / IP protocol stack in the body domain controller is used to package the window opening information obtained by the body domain controller into a SOME / IP message, and

[0081] Therefore, communication through the SOME / IP protocol can further improve data transmission efficiency and reliability. The SOME / IP message can carry more comprehensive window control information and window status information, making window control more convenient and efficient.

[0082] Figure 3 A schematic diagram illustrating communication based on the SOME / IP protocol according to an exemplary embodiment of the present disclosure is shown.

[0083] In some exemplary embodiments, Figure 3 As shown in the figure, communication based on the SOME / IP protocol is service-oriented. A window service can be predefined, where the body domain controller is the provider of the window service (i.e., the server), and the cockpit domain controller is the consumer of the window service (i.e., the client). The cockpit domain controller can call the window service of the body domain controller via Ethernet.

[0084] The window service interface element type can include Method type and Event type. The cockpit domain controller can send a window control request to the body domain controller through the Method interface, and the body domain controller notifies the window status information through the Event interface.

[0085] When the system is started, the body domain controller and the cockpit domain controller first establish a connection through the service discovery mechanism to complete the client's service subscription to the server.

[0086] When a window is opened or closed, the window soft switch on the central control screen or mobile terminal interface is operated (the soft switch consists of four sliders, one for each window's opening percentage). After receiving the window opening percentages, the client-side cockpit domain controller packages this information into a SOME / IP Method request message and sends it to the server-side body domain controller via the Ethernet bus. The Method request message carries a structured data structure, including the following: the left front window opening setting information, the right front window opening setting information, the left rear window opening setting information, and the right rear window opening setting information.

[0087] The server-side body domain controller parses the Method request message and converts it into control instructions for the four windows. It then sends them to the window actuators for execution, thereby controlling the opening of the four windows.

[0088] The server-side body domain controller also determines whether the window opening and closing is successful and sends this information back to the client-side cockpit domain controller via a Method response message. The central control screen or mobile terminal interface will display a message indicating "window opening and closing successfully" or "window opening and closing failed."

[0089] The body domain controller uses window sensors to collect real-time information about the position and status of the four windows. When the server-side body domain controller detects a change in the position of a window, it immediately packages the current opening information of the four windows into a SOME / IP Event message and notifies the client-side cockpit domain controller of this SOME / IP Event message, which is then fed back to the central control screen to display the opening status of the four windows. The Event message carries a structured data structure containing the opening status of the left front window, the right front window, the left rear window, and the right rear window.

[0090] The intelligent network controller (TBOX) will also obtain the opening status information of the four windows in real time and upload it to the cloud via the mobile network or Wi-Fi. The cloud will send the opening information of the four windows to the mobile terminal, and the user can view the opening information of the four windows in the corresponding application interface of the mobile terminal.

[0091] In some exemplary embodiments, the packaging and parsing of the above-mentioned messages may be implemented by a message conversion module based on the SOME / IP protocol integrated in the vehicle body domain controller and the cockpit domain controller.

[0092] Based on the application of the SOME / IP communication protocol and the pre-defined window service, the subscription and publication of the window service are realized through the service discovery mechanism, so that data can be exchanged between the client and the server only when the client requests or the server notifies a specific subscriber (that is, service-oriented communication). Compared with the automotive electrical and electronic architecture (E / E architecture) in the related technology, in which each electronic control unit (ECU) communicates through signals, service-oriented communication enables controllers to exchange data only when there is a need, which can greatly reduce bandwidth waste.

[0093] In addition, when the window function needs to be upgraded or expanded, only the relevant service interface needs to be updated. Other controllers calling the service will not be affected, enhancing the scalability of the system. The window control system takes into account the application scenario of window service calls based on SOME / IP protocol communication. The window control and window opening status data are transmitted between domain controllers via Ethernet SOME / IP. Different from the traditional bus-type network that transmits information through the CAN bus, it improves the transmission rate and realizes high-bandwidth communication, making window control more convenient and efficient.

[0094] According to an embodiment of the present disclosure, an autonomous driving vehicle is also provided, comprising any of the above-mentioned window control systems.

[0095] Any window control system of the embodiments of the present disclosure can be applied to the autonomous driving vehicles in the embodiments of the present disclosure and can achieve the same technical effects. To avoid repetition, they will not be described here.
