Description

Technical Field

[0001] This application relates to the field of vehicle wiring harness technology, and in particular to a wiring harness connection system, a vehicle control method, and a vehicle. Background Technology

[0002] As intelligent vehicle technology continues to advance, vehicles are able to perform more and more functions. To achieve these functions, more actuators (such as motors, solenoid valves, relays, sensors, etc.) need to be installed on the vehicle, which leads to increasingly complex wiring harness connections between the actuators and the vehicle's domain controller.

[0003] In related technologies, most actuators on a vehicle are connected to a domain controller via wiring harnesses. Since the domain controller is generally located in the center console of the vehicle, the wiring harness between actuators that are far away (such as the trunk motor) and the domain controller may need to cross the cabin, which undoubtedly increases the complexity of the wiring harness layout and also increases the cost of the wiring harness. Summary of the Invention

[0004] This application provides a wiring harness connection system, a vehicle control method, and a vehicle, which simplifies the wiring harness connection between actuators and domain controllers, reduces the complexity of wiring harness layout, and saves the cost of wiring harnesses.

[0005] In a first aspect, embodiments of this application provide a wiring harness connection system applied to a vehicle, the vehicle being divided into at least two areas; the wiring harness system includes a domain controller in the vehicle, actuators and relay devices disposed in the at least two areas, and a first wiring harness and a second wiring harness.

[0006] The domain controller can be a vehicle control unit (VCU), vehicle information unit (VIU), or vehicle domain controller (VDC) that implements vehicle control. It can also be an intelligent driving domain control unit or a mobile data center (MDC) used to implement intelligent driving or assisted driving functions. Actuators can be motors, solenoid valves, relays, sensors, lidar, distance sensors, millimeter-wave radar, etc. The relay device is a transfer device, and its specific form is not limited. The first and second wiring harnesses can be the same automotive wiring harness; to distinguish the connection relationship between the domain controller, actuators, and relay devices, the automotive wiring harness is named the first and second wiring harnesses.

[0007] In the wiring harness connection system of this application, the connection relationship between the domain controller, actuator, and relay device is as follows: for any one of at least two regions, the actuator in that region is connected to the relay device in that region via a first wiring harness, and the relay device in that region is connected to the domain controller via a second wiring harness, wherein the number of the second wiring harness is less than the number of the first wiring harness.

[0008] Regarding this connection, the domain controller, actuators, and relays function as follows: the domain controller controls the actuators; the relays forward signals and distribute power; and the actuators implement the vehicle's functions (such as window operation and trunk opening / closing). For example, the domain controller sends control signals and receives feedback signals; the relays send control signals to the corresponding actuators and send feedback signals from the actuators back to the domain controller; and the actuators respond to the control signals by performing corresponding operations and sending feedback signals of the performed operations to the relays.

[0009] Based on the above description, actuators within a region are only connected to the relay harnesses within that region, rather than directly to the domain controller harnesses. This undoubtedly shortens the harness connection distance and saves on the cost of the harnesses within that region. Furthermore, considering that each actuator is connected to its corresponding relay via at least one first harness, and that there are generally multiple actuators within a region, the number of first harnesses is relatively large. Therefore, the number of second harnesses is less than (or even significantly less than) the number of third harnesses (or, in other words, the number of harnesses between each relay and the domain controller is less than the number of harnesses between that relay and the actuator), reducing the number of harnesses that need to be directly connected to the domain controller, i.e., reducing the number of harnesses that need to cross the cabin, thereby reducing the complexity of the overall vehicle harness layout and simplifying the overall vehicle harness connection.

[0010] In one possible design, each of the at least two regions is equipped with a relay device. This design aims to enable the actuator in each region to connect to the relay device in its respective region, thereby shortening the wiring harness connection distance and saving on the cost of the wiring harness required in that region.

[0011] In one possible design, any two of the at least two regions do not overlap. This design ensures that no two of the at least two regions contain the same actuator, thus preventing an actuator from being located in different regions and guaranteeing the rationality of the wiring harness connection.

[0012] In one possible design, the at least two areas include multiple door areas. This design is for dividing the vehicle's doors into zones to simplify the process of zone division.

[0013] In one possible design, the number of door zones is the same as the number of doors in the vehicle. Alternatively, each door of the vehicle belongs to a separate zone, thus avoiding the wiring harness connecting the actuators on the doors to the relay devices crossing the cabin.

[0014] In one possible design, the relay device in each door area is positioned on the side of the corresponding door closest to its connection point with the vehicle body. This design takes into account that the domain controller is located on the vehicle body, thereby shortening the wiring harness connection distance between the relay device and the domain controller.

[0015] In one possible design, the at least two areas further include at least one area within the vehicle body area, the front compartment area, and the rear compartment area. This design divides the vehicle into areas to ensure the rationality of the vehicle's wiring harness connections.

[0016] In one possible design, the relay devices in the vehicle body area are respectively located at the positions of the front seats and the rear seats, the relay devices in the front compartment area are respectively located on both sides of the front of the vehicle and close to the domain controller, and the relay devices in the rear compartment area are located on either side of the rear of the vehicle.

[0017] Optionally, the at least two areas include four door areas, one body area, one front cabin area, and one rear cabin area. Each of the four door areas has one relay device, the body area has two relay devices, the front cabin area has two relay devices, and the rear cabin area has one relay device.

[0018] In one possible design, there are two domain controllers, and the relay devices in at least two areas are connected to one of the domain controllers via a second wiring harness according to the principle of proximity. This design can shorten the wiring harness connection distance between the relay devices and the domain controllers, thereby reducing the complexity of the vehicle's wiring harness layout and further saving the overall vehicle wiring harness cost. Optionally, one domain controller is located at the driver's seat and the other domain controller is located at the passenger's seat.

[0019] In one possible design, the first wiring harness includes one or more of the following: a Controller Area Network (CAN) bus, a Local Area Network (LIN) bus, a MOST bus, and a FlexRay bus; similarly, the second wiring harness includes one or more of the following: a Controller Area Network (CAN) bus, a Local Area Network (LIN) bus, a MOST bus, and a FlexRay bus.

[0020] Secondly, this application also provides a vehicle control method, which is applied to the relay device described in the first aspect above. Taking a first relay device as an example, the first relay device is disposed in a first area of ​​the vehicle, a first actuator is disposed in the first area, the first actuator is connected to the first relay device via a first wiring harness, and the first relay device is connected to a domain controller disposed on the vehicle via a second wiring harness; based on this, the method includes:

[0021] The first relay device receives a control signal from the domain controller, the control signal indicating the operation to be performed by the first actuator, the control signal including an identifier of the first actuator;

[0022] The first relay device sends the control signal to the first actuator based on the identifier of the first actuator, so that the first actuator performs the operation indicated by the control signal.

[0023] In one possible design, the method further includes: the first relay device receiving a feedback signal from a first actuator, the feedback signal indicating the execution status and / or execution result of the first actuator; the first relay device sending the feedback signal to the domain controller to cause the domain controller to respond to the feedback signal.

[0024] In one possible design, the relay device includes a first I / O interface and a second I / O interface. The first I / O interface is connected to one end of the first wiring harness, and the second I / O interface is connected to one end of the second wiring harness. The other end of the first wiring harness is connected to an actuator, and the other end of the second wiring harness is connected to a domain controller. Since the number of second wiring harnesses is less than the number of first wiring harnesses, the number of second I / O interfaces is less than the number of first I / O interfaces.

[0025] In one possible design, the first relay device further includes a forwarding module, which is used to send the control signal to the first actuator according to the identifier of the first actuator in the control signal; the forwarding module is also used to...

[0026] Thirdly, this application also provides a vehicle control method, which is applied to a domain controller as described in the first aspect above. The domain controller is connected to a first relay device via a second wiring harness. The first relay device is disposed in a first area of ​​the vehicle, and a first actuator is disposed in the first area. The first actuator is connected to the first relay device via the first wiring harness. The method includes:

[0027] The domain controller sends a control signal to the first relay device. The control signal indicates the operation that the first actuator needs to perform. The control signal includes an identifier of the first actuator. The identifier of the first actuator is used by the first relay device to send the control signal to the first actuator so that the first actuator performs the operation indicated by the control signal.

[0028] In one possible design, the method further includes:

[0029] The domain controller receives a feedback signal from the first relay device, the feedback signal being sent to the first relay device by the first actuator, the feedback signal indicating the execution status and / or execution result of the first actuator;

[0030] The domain controller responds to the feedback signal.

[0031] Fourthly, this application also provides a vehicle comprising the wiring harness connection system described in the first aspect above. The wiring harness connection system includes a domain controller, a first relay device, a first actuator, and a first wiring harness and a second wiring harness. The first actuator and the first relay device are disposed within a first region, which is any one of at least two regions into which the vehicle is divided. The domain controller is connected to the first relay device via the second wiring harness, and the first actuator is connected to the first relay device via the first wiring harness. The first relay device is used to implement the vehicle control method described in the second aspect above, and the domain controller is used to implement the vehicle control method described in the third aspect above.

[0032] In some embodiments, the vehicle includes a new energy vehicle, a hybrid vehicle, a range-extended electric vehicle, or a gasoline vehicle. The dimming glass design of this application can be applied to vehicles with different power types to reduce overall vehicle costs and ensure the user's driving experience.

[0033] The technical effects that can be achieved by the second, third and fourth aspects mentioned above can be described with reference to the technical effects that can be achieved by any design in the first aspect mentioned above, and the repetitions will not be discussed.

[0039] Figure 6 This is a flowchart illustrating a vehicle control method provided in an embodiment of this application. Detailed Implementation

[0040] As intelligent vehicle technology continues to advance, vehicles are able to perform more and more functions. To achieve these functions, more actuators (such as motors, solenoid valves, relays, sensors, etc.) need to be installed on the vehicle, which leads to increasingly complex wiring harness connections between the actuators and the vehicle's domain controller.

[0041] Please see Figure 1 , Figure 1 This diagram illustrates an application scenario applicable to an embodiment of this application. In this scenario, the vehicle includes a domain controller (represented by a black circle in the diagram) and multiple actuators (represented by black triangles in the diagram). The domain controller can be located on the center console of the vehicle, and the multiple actuators are located in different positions on the vehicle (such as the front door, rear door, and rear of the vehicle) based on their functions. The actuators are connected to the domain controller via wiring harnesses (described by dashed lines in the diagram).

[0042] As can be seen, the wiring harness between actuators that are far away (such as actuators at the rear door or the rear of the vehicle) and the domain controller needs to cross the cabin (such as the front and rear cabins), which undoubtedly increases the complexity of the wiring harness layout and also increases the cost of the wiring harness.

[0043] Therefore, embodiments of this application provide a wiring harness connection system to simplify the wiring harness connection between the actuator and the domain controller, reduce the complexity of the wiring harness layout, and save the cost required for the wiring harness.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0045] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0046] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0047] The wiring harness connection system in this application embodiment can be applied to vehicle-to-everything (V2X), long-term evolution-vehicle (LTE-V), and vehicle-to-vehicle (V2V) communication. For example, it can be applied to vehicles with driving mobility functions, or devices with driving mobility functions, such as intelligent transportation equipment, smart home devices, and robots. Optionally, the vehicle can be a car, truck, motorcycle, bus, ship, airplane, helicopter, lawnmower, recreational vehicle, amusement park vehicle, construction equipment, tram, golf cart, train, etc. This application embodiment does not limit the specific form of the vehicle.

[0048] This application uses a four-door sedan as an example. Please refer to [link / reference]. Figure 2 , Figure 2 This is a schematic diagram illustrating the division of a vehicle into regions according to an embodiment of this application. The vehicle is divided into at least two regions (as shown by the dashed boxes in the diagram). It should be noted that the number of regions divided into the vehicle can be preset based on experience, and this application does not limit the number or method of region division.

[0049] In one possible implementation, at least two areas comprise only door areas, meaning the vehicle doors are divided into at least two door areas. Optionally, the number of door areas is the same as the number of vehicle doors, meaning each vehicle door belongs to one door area, thus avoiding the wiring harness connecting the actuators on the doors to the relay devices crossing the cabin. Alternatively, there may be multiple door areas; for example, the left-side door of the vehicle may belong to one door area, and the right-side door may belong to another door area; or, for example, the front doors of the vehicle may belong to one door area, and the rear doors may belong to another door area. This application does not limit the number or method of dividing the door areas.

[0050] In one possible implementation, at least two areas include, in addition to the door area, at least one of the following: a body area, a front compartment area, and a rear compartment area. For example, the vehicle is divided into a door area, a body area, a front compartment area, and a rear compartment area. Optionally, there may be only one front compartment area, one rear compartment area, and one body area. This is to avoid an excessive number of relay devices and wiring harnesses due to too many area divisions, thereby controlling costs.

[0051] It is understood that at least two areas can be freely divided according to needs. For example, at least two areas may only include the vehicle body area, the front compartment area, and the rear compartment area. Therefore, this application does not impose specific restrictions on the content included in at least two areas. This application will now use the example of at least two areas including the door area, the vehicle body area, the front compartment area, and the rear compartment area.

[0052] like Figure 2 The four-door vehicle shown comprises at least two areas: four door areas (door area 1, door area 2, door area 3, and door area 4), one front cabin area, one rear cabin area, and one body area (i.e., all areas of the vehicle other than the door areas, front cabin area, and rear cabin area). It is understood that the vehicle can be divided into more areas, such as a left front cabin area, a right front cabin area, a left rear cabin area, and a right rear cabin area, etc. This application does not limit the number of areas.

[0053] In one possible implementation, at least two regions do not overlap. This ensures that a location in the vehicle (or the location of an actuator) belongs to only one region, preventing an actuator from being located in different regions and guaranteeing the rationality of wiring harness connections.

[0054] Based on the aforementioned regions, the following describes the components included in the wiring harness connection system: the wiring harness system includes a domain controller in the vehicle, actuators and relays disposed in at least two regions, and a first wiring harness and a second wiring harness.

[0055] The domain controller can be a vehicle control unit (VCU), vehicle information unit (VIU), or vehicle domain controller (VDC) that implements vehicle control. It can also be a smart driving domain control unit or mobile data center (MDC) used to implement smart driving or driver assistance functions. Actuators can be motors (such as door lock motors, window motors, etc.), solenoid valves, relays, sensors, lidar, distance sensors, millimeter-wave radar, etc. A relay device is used for signal forwarding and power distribution; its specific form is not limited. The first and second wiring harnesses can be the same automotive wiring harness. To distinguish the connection relationship between the domain controller, actuators, and relay devices, the automotive wiring harness is named the first and second wiring harnesses.

[0056] Optionally, the first wiring harness may include one or more of the following: Controller Area Network (CAN) bus, Local Interconnect Network (LIN) bus, MOST bus, FlexRay bus, Peripheral Component Interconnect (PCI) bus, Extended Industry Standard Architecture (EISA) bus, Inter-Integrated Circuit (I2C) bus, etc. The bus can be categorized as an address bus, data bus, control bus, etc. For ease of illustration, the first wiring harness is represented by a thin solid line in the diagram below, but this does not imply that there is only one first bus or only one type of bus.

[0057] Similarly, the second wiring harness may include one or more of the following: CAN bus, LIN bus, MOST bus, FlexRay bus, PCI bus, EISA bus, I2C, etc. For ease of illustration, the second wiring harness is represented by a thick solid line in the figure below, but this does not imply that there is only one bus or one type of bus. It should be noted that, depending on the requirements, the first or second wiring harness may also include other types of buses, and this application does not limit the type of bus in the wiring harness.

[0058] In one possible implementation, a relay device is provided in each of at least two regions. This enables the actuators in each region to connect to the relay device in their respective region, thereby shortening the connection distance of the required wiring harness and saving the cost of the wiring harness in that region. It should be noted that the number of relay devices provided in each region can be determined based on the vehicle size and / or the number of actuators, thereby ensuring the real-time forwarding of signals by the relay devices and the reliability of power distribution. This application does not limit this aspect.

[0059] Optionally, one relay device is installed in each of the multiple door areas (this application takes four door areas as an example), two relay devices are installed in the body area, two relay devices are installed in the front compartment area, and one relay device is installed in the rear compartment area. Figure 2 The vehicle shown is an example where the VIU is a domain controller. Please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of a wiring harness connection system provided in an embodiment of this application. The system includes a domain controller (VIU as an example), actuators, and relay devices. Relay devices 1 and 2 belong to the front vehicle compartment area, relay device 3 belongs to door area 1, relay device 4 belongs to door area 2, relay device 5 belongs to door area 3, relay device 6 belongs to door area 4, relay devices 7 and 8 belong to the vehicle body area, and relay device 9 belongs to the rear vehicle compartment area. For any relay device, the actuator connected to that relay device via a wiring harness belongs to the same area. For example, the actuator connected to relay device 1 via a wiring harness belongs to the front vehicle compartment area. It should be noted that an actuator is a device installed on the vehicle to perform a certain function. This embodiment of the application does not limit the number of actuators; the illustrations simply use 2 or 3 actuators for illustration.

[0060] based on Figure 3 In the wiring harness connection system, the connection relationship between the domain controller, actuator, and relay device is as follows: For any one of at least two regions, the actuator in that region is connected to the relay device in that region via a first wiring harness (shown as a thin solid line in the diagram), and the relay device in that region is connected to the domain controller via a second wiring harness (shown as a thick solid line in the diagram). In other words, while in related technologies the actuator is directly connected to the domain controller, in this embodiment, the actuator is connected to the domain controller via a relay device.

[0061] It is understandable that the communication protocol between the actuator and the relay device is associated with the bus type contained in the first wiring harness. For example, if the first wiring harness contains a CAN bus, then the communication protocol between the actuator and the relay device includes the CAN bus protocol. Similarly, the communication protocol between the relay device and the domain controller is associated with the bus type contained in the second wiring harness.

[0062] Furthermore, the relay device includes a first input / output (I / O) interface and a second I / O interface; wherein, the first I / O interface is used to connect to one end of the first wiring harness, the second I / O interface is used to connect to one end of the second wiring harness, the other end of the first wiring harness is connected to the actuator, and the other end of the second wiring harness is connected to the domain controller.

[0063] The first I / O interface may include one or more of the following: High Definition Multimedia Interface (HDMI), Universal Serial Bus (USB) interface, General-purpose input / output (GPIO) interface, Universal Asynchronous Receiver and Transmitter (UART) interface, and Serial Peripheral Interface (SPI).

[0064] Similarly, the second I / O interface may include one or more of the following: HDMI, USB, GPIO, UART, and SPI. It should be noted that, depending on requirements, the first or second I / O interface may also include other types of interfaces; this application does not limit the type of interface in the relay device.

[0065] In this embodiment, the number of second wiring harnesses is less than the number of first wiring harnesses. Based on this, it can be understood that the number of second I / O interfaces is less than the number of first I / O interfaces.

[0066] The number of first wire harnesses refers to the number of wire harnesses between the relay device and the actuators it needs to connect to. The number of first wire harnesses is positively correlated with the number of actuators. Generally, an actuator requires at least one first wire harness to connect to the relay device; that is, each actuator is connected to its corresponding relay device through at least one first wire harness. For ease of description, this embodiment of the application uses the example of one actuator requiring one first wire harness, meaning the number of first wire harnesses is the same as the number of actuators.

[0067] The number of second wiring harnesses refers to the number of wiring harnesses between the relay device and the domain controller. It should be noted that the number of second wiring harnesses is determined considering factors such as signal real-time requirements, the number of actuators, and power distribution requirements. Since the domain controller generally does not send a large number of control signals simultaneously, and some actuators have low latency requirements for control signals, the number of second wiring harnesses is set to be less than the number of first wiring harnesses. In other words, the number of wiring harnesses between each relay device and the domain controller (the number of second wiring harnesses) is less than (or less than) the number of wiring harnesses between that relay device and the actuators it is connected to (or the number of actuators, i.e., the number of first wiring harnesses).

[0068] In summary, compared to related technologies where each actuator connects directly to the domain controller, each actuator connects only to the relay device within its assigned area. This undoubtedly shortens the wiring harness connection distance and saves on wiring harness costs. Furthermore, considering that each actuator connects to its corresponding relay device via at least one first wiring harness, and that there are typically multiple actuators within an area, the number of first wiring harnesses is relatively large. Therefore, because the number of wiring harnesses between the relay device and the domain controller is reduced, the number of wiring harnesses that need to directly connect to the domain controller is decreased, meaning the number of wiring harnesses that need to cross the cabin is reduced. This reduces the complexity of the overall vehicle wiring harness layout and simplifies the overall vehicle wiring harness connection.

[0069] In one possible implementation, there are two domain controllers, VIU0 and VIU1. (See reference) Figure 3 At least two relay devices within a given area are connected to one of the domain controllers via a second wiring harness, following the principle of proximity. For example, relay device 1 is closest to VIU0, so relay device 1 is connected to VIU0 via the second wiring harness. This shortens the wiring harness connection distance between the relay device and the domain controller, thereby reducing the complexity of the vehicle's wiring harness layout and further saving on the vehicle's wiring harness cost.

[0070] In the embodiments of this application, the location of the domain controller and actuators on the vehicle depends on the vehicle design and the specific functions implemented, and this application does not limit this. For example, the domain controller may be located in the central control position of the vehicle, and the actuators may be located in the doors, seats, trunk, etc. Optionally, there may be two domain controllers, one of which may be located in the driver's seat and the other in the passenger seat.

[0071] The location of the relay device on the vehicle can be determined based on the vehicle design and the location of the domain controller. Figure 3 Please refer to the vehicle shown. Figure 4 , Figure 4This is a schematic diagram illustrating the location of a relay device on a vehicle, as provided in an embodiment of this application. The relay device in each door area is positioned on the side of the corresponding door closest to its connection point with the vehicle body, thus shortening the wiring harness distance between the relay device in the door area and the domain controller. Relay devices in the vehicle body area are located at the positions of the front and rear seats, ensuring a short wiring harness distance between the actuators and the relay devices within the vehicle body area. Relay devices in the front compartment area are located on both sides of the front of the vehicle, close to the domain controller, further shortening the wiring harness distance between the relay devices in the front compartment area and the domain controller. Relay devices in the rear compartment area are located on either side of the rear of the vehicle.

[0072] In summary, the following section uses a car door as an example to illustrate the differences between this application and related technologies. Please refer to [link / reference]. Figure 5 , Figure 5 This is a schematic diagram of a wiring harness for connecting an actuator on a vehicle door to a domain controller, provided in an embodiment of this application. Figure 5 Figure A in the diagram shows a direct connection between the actuator (represented by a black triangle in the diagram) and the domain controller (represented by a black circle in the diagram). Figure 5 Figure B in the diagram shows the connection between the actuator and the domain controller via a relay device (represented by a black square pattern in the diagram). The dashed line represents the wiring harness connecting the two devices. Figure 5 Taking three actuators as an example, let's assume... Figure 5 Figure A in the middle and Figure 5 In diagram B, the wiring harness path from the actuator to the connection point between the door and the body is the same (let the path distance be n), and the wiring harness path from the connection point between the door and the body to the domain controller is the same (let the path distance be m). Figure 5 In diagram B, the number of wiring harnesses between the relay device and the domain controller is one. Therefore, Figure 5 The required wire harness length L in diagram A is... A It is 3n+3m. Figure 5 The required wire harness length L in diagram B is... B It is 3n+1m. Therefore, it can be seen that... Figure 5 Figure B in the middle and Figure 5 Compared to Figure A in the previous version, the wiring harness connection of the entire vehicle is simplified, thereby reducing the complexity of the wiring harness layout and saving the cost required for the wiring harness.

[0073] Based on the above structure, the functions of the domain controller, relay device, and actuator are described below.

[0074] In this embodiment, the domain controller controls the actuators, the relay device forwards signals and distributes power, and the actuators implement the functions of the vehicle. These functions include, but are not limited to, the following: window operation, trunk operation, door locking / unlocking, and engine ignition. This embodiment does not limit the specific functions described herein.

[0075] Furthermore, the domain controller is used to send control signals and receive feedback signals, while the relay device is used to send control signals to the corresponding actuators and to send feedback signals from the actuators back to the domain controller. The actuators are used to respond to the control signals, perform corresponding operations, and send feedback signals to the relay device. The control signals indicate the operations that the actuators need to perform, and the feedback signals indicate the execution status and / or execution results of the actuators.

[0076] For an example, consider a domain controller, a first relay device, and a first actuator on a vehicle as the main execution components. Please refer to 6. Figure 6 This is a flowchart illustrating a vehicle control method provided in an embodiment of this application. A first actuator and a first relay device are disposed within a first region, which can be any of the aforementioned at least two regions (such as the left front door region). The first relay device and the first actuator are both disposed within the first region. It is understood that the first region may also include a second relay device, a second actuator, and more relay devices and actuators, which will not be elaborated upon here. A domain controller (such as a domain controller located in the driver's seat of the vehicle) is connected to the first relay device via a second wiring harness, and the first actuator is connected to the first relay device via a first wiring harness. Based on this, the method includes the following:

[0077] Step 601: The domain controller sends a control signal to the first relay device. The control signal indicates the operation that the first actuator needs to perform. The control signal includes the identifier of the first actuator.

[0078] based on Figure 2 For example, the first relay device is relay device 3 in door area 1, and the first actuator is the driver's side door window motor. The domain controller sends a control signal to relay device 3 in the door area, which instructs the driver's side door window motor to lower the driver's side door window. This control signal includes an identifier for the driver's side door window motor.

[0079] Step 602: The first relay device sends a control signal to the first actuator according to the identifier of the first actuator.

[0080] Based on the above example, the relay device 3 sends the control signal to the window motor of the driver's side door according to the identification of the window motor of the driver's side door.

[0081] Step 603: The first actuator performs the operation indicated by the control signal.

[0082] Based on the above example, the driver's side door window motor is powered on, and the driver's side door window is lowered.

[0083] Step 604: The first actuator sends a feedback signal to the first relay device, the feedback signal indicating the execution status and / or execution result of the first actuator.

[0084] Based on the above example, the feedback signal indicates that the driver's side door window has been successfully lowered, as well as the state of the lowering (e.g., the window is lowered by 50%).

[0085] Step 605: The first relay device forwards the feedback signal to the domain controller.

[0086] Step 606: The domain controller responds with a feedback signal.

[0087] Based on the above example, after the domain controller responds to the feedback signal, it can provide a prompt on the information indicated by the feedback signal, such as displaying on the screen that the window has been successfully lowered and that the window has been lowered to 50%. This application does not limit the prompting method.
