Description

Technical Field

[0002] With the rapid development of intelligent, electric, and connected vehicles, the number of automotive electronic and electrical equipment has increased dramatically compared to traditional vehicles, leading to the deployment of more control units (ECUs) in the electronic and electrical architecture. This means an increase in the number of messages in the bus, increased network complexity, and even the development of multiple gateway frameworks such as a central gateway and subnets. Furthermore, due to the complex and ever-changing vehicle environment, the global network management side coordinates the network status of various nodes to control the communication behavior between nodes, thereby increasing vehicle safety and stability. At the same time, local network management further improves energy efficiency.

[0003] Currently, network management of the central gateway, sub-gateways, and subnet controllers involves timing issues. The use of network management message suspension and timeout mechanisms to achieve coordinated sleep results in time differences between subnets and communication fault monitoring between controllers.

[0064] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0065] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0066] The main solution of this application embodiment is as follows: The control unit acquires a target scene signal, obtains the control unit status based on the target scene signal, generates a target scene message based on the target scene signal, and sends the target scene message to the regional gateway through the subnet segment; the regional gateway receives the target scene message, obtains the regional gateway status based on the target scene message, and sends the target scene message to the central gateway based on the backbone network; the central gateway receives the target scene message, obtains the central gateway status based on the target scene message; and local network collaborative control is achieved based on the control unit status, the regional gateway status, and the central gateway status.

[0067] In this embodiment, for ease of description, the following description will focus on identifying local network collaborative control devices as the execution subject.

[0068] With the rapid development of intelligent, electric, and connected vehicles, the number of electronic and electrical components in automobiles has increased dramatically compared to traditional vehicles, leading to the deployment of more control units (ECUs) within the electronic and electrical architecture. This means an increase in the number of messages on the bus, increased network complexity, and even the development of multiple gateway frameworks such as a central gateway and subnets. Furthermore, due to the complex and ever-changing vehicle environment, the global network management side coordinates the network status of various nodes to control the communication behavior between nodes, thereby increasing vehicle safety and stability. At the same time, local network management further enhances energy efficiency.

[0069] Currently, network management of the central gateway, sub-gateways, and subnet controllers involves timing issues. The use of network management message suspension and timeout mechanisms to achieve coordinated sleep results in time differences between subnets and communication fault monitoring between controllers. If the sleep interval between different subnets is long, it can lead to false fault recording.

[0070] This application provides a solution that generates a target scenario message by determining the currently active scenario, and sends the target scenario message to various control units, regional gateways, and central gateways. Each node can then identify whether the target scenario message activates it, thus avoiding the timeout mechanism of the regional gateway and central gateway during the control process that causes a sleep / activation time difference between nodes, and achieving rapid response and collaborative control among the nodes.

[0071] As can be seen from the above embodiments, this application discloses a local network cooperative control method: the control unit acquires a target scene signal, obtains the control unit state based on the target scene signal, generates a target scene message based on the target scene signal and sends it to the regional gateway; the regional gateway receives the target scene message, obtains the regional gateway state based on the target scene message and sends it to the central gateway; the central gateway receives the target scene message and obtains the central gateway state based on the target scene message; local network cooperative control is realized based on the control unit state, the regional gateway state, and the central gateway state; this method generates a message through the currently active scene, sends the message to each control unit, regional gateway, and central gateway, etc., and each node identifies the message to determine whether to activate / dormant the node, avoiding the activation / dormant time difference between each node caused by the timeout mechanism of the regional gateway and the central gateway during the control process, and realizing fast response and cooperative control between each node.

[0072] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or local network collaborative control device capable of performing the above functions. The following description uses a local network collaborative control device as an example to illustrate this embodiment and the subsequent embodiments.

[0073] Based on this, embodiments of this application provide a local network cooperative control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the local network cooperative control method of this application.

[0074] In this embodiment, the local network cooperative control method is applied to a local network cooperative control system, which includes a central gateway, at least one regional gateway, and at least one control unit. The central gateway and the regional gateway are connected via a backbone network, and the regional gateway and the control unit are connected via a subnet segment. The method includes steps S10 to S40:

[0075] Step S10: Obtain the target scene signal through the control unit, obtain the control unit status based on the target scene signal, generate a target scene message based on the target scene signal, and send the target scene message to the area gateway through the subnet segment.

[0076] Understandably, a control unit can be a controller for various vehicle functions installed in the vehicle's electronic and electrical architecture, such as a turn signal controller, Bluetooth controller, seat status controller, etc.

[0077] It should be understood that the target scenario signal can be a signal generated when a vehicle user performs relevant operations based on the current driving needs of the vehicle. For example, when a vehicle is about to turn left at an intersection, it turns on the left turn signal, and at this time the vehicle's turn signal control unit receives the left turn scenario signal.

[0078] It should be noted that the target scene signal can be obtained by different control units. For example, the left turn scene signal can be obtained by the turn signal control unit, and the Bluetooth connection scene signal can be obtained by the Bluetooth controller, etc.

[0079] It should be understood that the control unit can be active or dormant. When a user activates a function, the controller corresponding to that function receives a scene signal and identifies the controller's state as active; when a user deactivates a function, the controller corresponding to that function receives a scene signal and identifies the controller's state as dormant.

[0080] It should be noted that the target scene is triggered by the target scene signal, but the target scene may not only involve this one control unit, but may also involve other control units, area gateways, central gateways, etc.

[0081] It should be noted that a target scene message is generated based on the target scene signal. The target scene message format can be found in Table 1 below:

[0082]

[0083] Among them, Byte2 to Byte7 of the message are scene groups, and scene 1 to scene 48 are defined according to different functions. If scene 48 is activated based on the target scene signal, then the processing bit of "scene 48" in the table is "0x1", which means that scene 48 is activated.

[0084] It should be noted that in the local network collaborative control system, the control unit is connected to the regional gateway through a subnet segment. It should be emphasized that when the control unit under the regional gateway is activated, the regional gateway will be activated, and the central gateway of the regional gateway will also be activated.

[0085] It should be further explained that the central gateway includes at least one regional gateway connected to the backbone network, and the backbone network connects the central gateway and at least one regional gateway; the regional gateway includes at least one control unit connected to a subnet segment, and the subnet segment connects at least one regional gateway and at least one control unit. For specific structural relationships, please refer to [reference needed]. Figure 2 , Figure 2 The structural relationship diagram of a single control unit includes a central gateway, a regional gateway 1 connected to the central gateway via the main network, and a control unit (i.e., the ECU in the diagram) connected to the regional gateway 1 via a subnet segment.

[0086] In one feasible implementation, obtaining the target scene signal through the control unit in step S10 may include steps A1001~A1002:

[0087] Step A1001: Obtain vehicle control commands through the control unit.

[0088] It should be noted that vehicle control commands can be voice control commands input by the user, such as turning on the air conditioner, starting the vehicle, closing the windows, turning off the music, etc.

[0089] Step A1002: Generate a target scene signal according to the vehicle control command. The target scene signal includes a target scene activation signal and a target scene sleep signal, so that the local network cooperative control system controls the central gateway, regional gateway and control unit to activate or sleep in coordination based on the target scene activation signal and the target scene sleep signal.

[0090] Understandably, the target scene signal can be a signal generated when the current scene is determined based on vehicle control commands.

[0091] It should be noted that the target scene signal generates a message and sends the message to each node of the local network collaborative control system (control unit node, regional gateway node, central gateway node). The message is transmitted between the nodes very quickly, in milliseconds. After receiving the message, each node activates or suspends its activity based on the target scene in the message. If the target scene is related to the node, the node will activate or suspend its activity synchronously.

[0092] In this embodiment, by transmitting the target scenario message between each node, the node itself determines whether to activate or hibernate based on the target scenario message. This avoids the traditional activation / hibernation transmission method, where the regional gateway needs to send a hibernation signal to the central gateway, wait for the central gateway to time out, and then send a hibernation signal back to each control unit. The timeout response is calculated in seconds, resulting in a long delay and a long time difference between the hibernation time of the central gateway and each control unit.

[0093] The above is only a feasible implementation method for obtaining the target scene signal through the control unit in step S10 of this embodiment. This embodiment does not specifically limit the specific implementation method for obtaining the target scene signal through the control unit in step S10.

[0094] Step S20: Receive the target scenario message through the regional gateway, obtain the regional gateway status based on the target scenario message, and send the target scenario message to the central gateway based on the backbone network.

[0095] Understandably, the status of a regional gateway includes active and dormant states.

[0096] Understandably, the relationship between the area gateway and each control unit can be understood as follows: if any one or more control units under the area gateway are activated, the area gateway will also be activated. Simply put, as long as a control unit is activated, the area gateway connected to that control unit will definitely be activated; if all control units under the area gateway are dormant, the area gateway will be dormant.

[0097] Understandably, regional gateways are connected to the central gateway via the backbone network. The central gateway can connect to multiple regional gateways through one backbone network, or it can connect to multiple regional gateways through multiple backbone networks respectively.

[0098] In one feasible implementation, obtaining the area gateway status based on the target scenario message in step S20 may include steps A2001~A2003:

[0099] Step A2001: Parse the target scene message to obtain the scene status of each scene, including active state and dormant state.

[0100] It is understandable that parsing the target scenario message can involve each node identifying the identifier of each scenario in the message. Referring to Table 1 above, the identifier can be 0x0 or 0x1, and the node can determine whether each scenario is in an active or dormant state based on the identifier.

[0101] Step A2002: Obtain the associated scenarios of the regional gateway, and obtain the associated scenario status based on the scenario status of each scenario.

[0102] Understandably, the associated scenario can be a scenario where the regional gateway changes as the scenario changes.

[0103] It should be understood that each node can have one or more related scenarios. For example, the scenario related to the voice control unit can be related to the navigation scenario (the navigation scenario requires voice broadcast of the navigation route), the music playback scenario (speaker sound), etc.

[0104] It should be noted that the associated scene state can be one or more of the various scenes.

[0105] Step A2003: Obtain the regional gateway status based on the associated scenario status.

[0106] It should be noted that when all associated scene states are in a dormant state, the regional gateway state is also in a dormant state; if any one or more scene states are in an active state, the regional gateway state is also in an active state.

[0107] In this embodiment, by parsing the target scenario messages, the current state (active or dormant) of each scenario is accurately identified, thereby enabling granular control of different functional modules inside the vehicle. This improves the system's flexibility and adaptability, allowing the vehicle to respond more efficiently to different driving conditions and user needs, parse scenario messages in real time and adjust the regional gateway state accordingly, and respond quickly to changes.

[0108] The above is only a feasible implementation method for obtaining the regional gateway status based on the target scenario message in step S20 of this embodiment. This embodiment does not specifically limit the specific implementation method for obtaining the regional gateway status based on the target scenario message in step S20.

[0109] Step S30: Receive the target scenario message through the central gateway and obtain the central gateway status based on the target scenario message.

[0110] Understandably, the central gateway status can include both active and dormant states.

[0111] It should be noted that the relationship between the central gateway and the regional gateways can be compared to the relationship between the regional gateways and the control unit. If any one or more regional gateways under the central gateway are active, then the central gateway must be active and all regional gateways under the central gateway must be in a dormant state before the central gateway can enter a dormant state.

[0112] Step S40: Implement local network collaborative control based on the status of the control unit, the status of the regional gateway, and the status of the central gateway.

[0113] It is understandable that local network collaborative control based on the control unit status, the regional gateway status, and the central gateway status can be achieved by each node directly changing its status according to the status of the scenario related to each node in the message. The message transmission speed between nodes is fast, which enables collaborative control of each node.

[0114] This embodiment provides a local network collaborative control method. By determining the currently active scenario, a target scenario message is generated and sent to various control units, regional gateways, and central gateways. Each node can independently identify whether the target scenario message activates it. This avoids the timeout mechanism of the regional gateway and central gateway during the control process, which would cause a time difference between the dormant and active nodes, thus achieving rapid response and collaborative control among the nodes.

[0115] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 After step S10, the local network cooperative control method further includes steps S101 to S103:

[0116] Step S101: Send the target scenario message to the first target control unit through the subnet segment. The first target control unit is a control unit connected to the control unit through the same subnet segment.

[0117] Understandably, the target control unit and the control unit are connected to the area gateway through the same subnet segment.

[0118] It should be noted that the system architecture for a local network collaborative control system with multiple control units within the same subnet segment can be referenced. Figure 4 In the diagram, both ECU1 and ECU2 are connected to the regional gateway through subnet segments. If ECU1 is a control unit, then ECU1 acquires the target scene signal, generates a target scene message, and sends the target scene message to ECU2 (the target control unit) and the regional gateway through the subnet segment.

[0119] Step S102: The first target control unit receives the target scene message and obtains the status of the first target control unit based on the target scene message.

[0120] Understandably, the state of the first target control unit includes an active state and a dormant state. At this time, the state of the regional gateway can be understood as being affected by both the first target control unit and the control unit. However, in practice, the associated scenarios of ECU1 and ECU2 are both taken as the associated scenarios of the regional gateway. Therefore, regardless of whether ECU1 or ECU2 is active, the regional gateway will be activated because the associated scenario is active. Conversely, if ECU1 is dormant and ECU2 is dormant at the same time, the regional gateway will be dormant.

[0121] Step S103: Implement local network collaborative control based on the control unit status, the first target control unit status, the regional gateway status, and the central gateway status.

[0122] Understandably, the local network collaborative control system at this time includes multiple nodes such as control unit, first target control unit, regional gateway, and central gateway. Based on the target scenario message, the messages are quickly transmitted among the nodes to achieve collaborative control of the nodes.

[0123] It should be emphasized that in this embodiment, the first target control unit only refers to the control unit connected to the control unit through the same subnet segment, and there is no limitation on the number of the first target control units, which can also include multiple units.

[0124] This embodiment provides a local network collaborative control method, in which the control unit sends the target scene message to the first target control unit and the regional gateway connected in the same subnet segment, and then the regional gateway sends the target scene message to the central gateway. Based on the transmission of the scene message to each node, collaborative control of each node is realized.

[0125] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 After step S20, the local network cooperative control method further includes steps S201-S203:

[0126] Step S201: Send the target scenario message to the second target control unit through the target subnet segment. The second target control unit is connected to the area gateway through the target subnet segment.

[0127] It is understood that the target subnet segment and the subnet segment are respectively connected to the area gateway. There can be one or more target subnet segments. This embodiment only describes one subnet segment. The collaborative control method of other subnet segments is similar to that of the target subnet segment.

[0128] It should be noted that the system architecture for control units connected to multiple subnets under the same area gateway in a local network collaborative control system can refer to [reference needed]. Figure 6 In the diagram, ECU1 and ECU2 are both connected to the regional gateway via subnet segments. ECU1 is the control unit, ECU2 is the first control unit, and ECU3 is the second control unit. ECU1 and ECU2 are connected to the regional gateway via subnet segments, and ECU3 is connected to the regional gateway via a target subnet segment. If ECU1 acquires a target scene signal, generates a target scene message, and sends the target scene message to ECU2 (the first target control unit) and the regional gateway via a subnet segment, the regional gateway will then send the target scene message to ECU3 via the target subnet segment.

[0129] Step S202: The second target control unit receives the target scene message and obtains the status of the second target control unit based on the target scene message.

[0130] Understandably, the state of the second target control unit includes an active state and a dormant state.

[0131] It should be understood that the second target control unit is not directly connected to the control unit. After the area gateway receives the target scenario message, the area gateway then sends the target scenario message to the second target control unit to realize the transmission of the target scenario message between the various control units.

[0132] Step S203: Implement local network collaborative control based on the control unit status, the second target control unit status, the regional gateway status, and the central gateway status.

[0133] Understandably, the local network collaborative control system at this time includes multiple nodes such as control units, first target control units, second control units, regional gateways, and central gateways. Based on the target scenario messages, the messages are quickly transmitted among the nodes to achieve collaborative control of the nodes.

[0134] It should be understood that the second target control unit is connected to the area gateway through the target subnet segment, similar to how the control unit and the first control unit are connected to the area gateway through a subnet segment. Other control units may be connected to the area gateway and the second target control unit through the target subnet segment.

[0135] This embodiment provides a local network collaborative control method. After the control unit sends the target scene message to the regional gateway, the regional gateway sends the target scene message to the second target control unit through the target subnet segment. The regional gateway then sends the target scene message to the central gateway through the backbone network. Based on the transmission of the scene message to each node, collaborative control of each node is achieved.

[0136] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 7 After step S30, the local network cooperative control method further includes steps S301 to S305:

[0137] Step S301: The target scenario message is sent to the reference area gateway through the central gateway. The reference area gateway and the central gateway are connected through the reference backbone network.

[0138] It is understood that the backbone network and the reference backbone network are respectively connected to the central gateway. There can be one or more reference area gateways. This embodiment only describes the reference area gateway. The collaborative control method of other multiple reference area gateways is similar to that of the reference area gateway.

[0139] It should be noted that the system architecture of a local network collaborative control system, which includes multiple regional gateways connected to the backbone network under the same central gateway, can refer to [reference needed]. Figure 8 In the diagram, the regional gateway and the reference regional gateway are connected to the central gateway through the backbone network and the reference backbone network, respectively. If ECU1 is a control unit, it is transmitted to the central gateway through the subnet segment, regional gateway, and backbone network. The central gateway then sends the target scenario message to the reference regional gateway, which then sends it to each of its subordinate control units.

[0140] It should be emphasized that there is also a scenario where the reference area gateway and the area gateway are connected to the central gateway through the same backbone network. In this structure, after the area gateway receives the target scenario message, it synchronously sends the target scenario message to the central gateway and the reference area gateway. Then, the reference area gateway sends the target scenario message to the following control unit nodes.

[0141] In step S302, the reference area gateway receives the target scenario message and obtains the reference area gateway status based on the target scenario message.

[0142] Understandably, the reference area gateway status includes active and dormant states.

[0143] It should be understood that when there are multiple regional gateways, the state of the central gateway is related to the state of each regional gateway. However, in practice, the associated scenarios of the regional gateways and the associated scenarios of the reference regional gateways are both considered as associated scenarios of the regional gateways. Therefore, regardless of whether the regional gateway or the reference regional gateway is activated, the regional gateway will be activated because the state of the associated scenario is active. Conversely, if the regional gateway is dormant and the reference regional gateway is also dormant, then the regional gateway will be dormant.

[0144] It should be emphasized that in this embodiment, the reference area gateway refers only to the area gateway connected to the central gateway through another backbone network. The number of reference area gateways is not limited; there can be one or more.

[0145] In step S303, the reference area gateway sends a target scenario message to the reference control unit through a reference subnet segment, and the reference control unit is connected to the reference area gateway through the reference subnet segment.

[0146] Understandably, there can be multiple reference area gateways, each reference area gateway can connect to multiple reference subnets, and each subnet can connect to multiple reference control units.

[0147] It should be emphasized that each reference control unit can also be a control unit. Simply put, each control unit can acquire target scene signals and generate target scene messages. In a local network collaborative control system, multiple control units can simultaneously generate target scene messages for transmission within the system.

[0148] Step S304: The reference control unit receives the target scene message and obtains the reference control unit status based on the target scene message.

[0149] Understandably, the reference control unit state can include active and dormant states.

[0150] It should be noted that the reference subnet segment may include a first reference subnet segment and a second reference subnet segment, the reference control unit includes a first reference control unit and a second reference control unit, and the reference subnet segment includes a first reference subnet segment and a second reference subnet segment.

[0151] Step S305: Implement local network collaborative control based on the control unit status, the area gateway status, the central gateway status, the reference area gateway status, and the reference control unit status.

[0152] It should be emphasized that the process of the reference control unit receiving the target scenario message and obtaining the reference control unit status based on the target scenario message includes: the reference area gateway sending the target scenario message to the first reference control unit through a first reference subnet segment, the first reference control unit being connected to the reference area gateway through the first reference subnet segment; the first reference control unit receiving the target scenario message and obtaining the first reference control unit status based on the target scenario message; the reference area gateway sending the target scenario message to the second reference control unit through a second reference subnet segment, the first reference control unit being connected to the reference area gateway through the second reference subnet segment; the second reference control unit receiving the target scenario message and obtaining the second reference control unit status based on the target scenario message; and using the first reference control unit status and the second reference control unit status as the reference control unit status.

[0153] Among these, it is understandable that reference Figure 8The relationship between the reference area gateway and the first reference subnet segment, the second reference subnet segment, the first reference control unit, and the second reference control unit in the diagram is similar to the relationship between the area gateway and the subnet segment, the target subnet segment, the control unit, the first target control unit, and the second target control unit, and can be understood in a similar way.

[0154] This embodiment provides a local network collaborative control method. After the control unit sends the target scene message to the regional gateway, the regional gateway sends the target scene message to the second target control unit through the target subnet segment. The regional gateway then sends the target scene message to the central gateway through the backbone network. The central gateway then sends the target scene message to other regional gateways, which in turn send it to their subordinate control units. Based on the transmission of the scene message to each node, collaborative control of each node is achieved.

[0155] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the local network cooperative control method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0156] This application also provides a local network cooperative control device; please refer to [reference needed]. Figure 9 The local network collaborative control device includes:

[0157] The message generation module 10 is used to obtain a target scene signal through the control unit, obtain the control unit status based on the target scene signal, generate a target scene message based on the target scene signal, and send the target scene message to the area gateway through the subnet segment;

[0158] The message transmission module 20 is used to receive target scenario messages through the regional gateway, obtain the regional gateway status based on the target scenario messages, and send the target scenario messages to the central gateway based on the backbone network.

[0159] The message transmission module 20 is also used to receive target scenario messages through the central gateway and obtain the central gateway status based on the target scenario messages;

[0160] The collaborative control module 30 is used to implement local network collaborative control based on the status of the control unit, the status of the regional gateway, and the status of the central gateway.
