Description

Technical Field

[0001] The present application relates to the technical field of network management, and in particular to a network management method, electronic equipment, vehicle, computer-readable storage medium, and computer program product. Background Art

[0002] Traditional vehicle network management usually uses direct network management mode to send network management messages to put all electronic control units (ECUs) of the vehicle into a unified sleep state to reduce the energy consumption of the vehicle. This network management mode can effectively reduce unnecessary power consumption and improve battery efficiency.

[0003] However, in an emergency situation, the direct network management mode may control the sleep mode of the entire vehicle, which may cause the key emergency system functions to fail to wake up. For example, the vehicle cannot turn on the emergency lights in an emergency situation. If the entire vehicle ends the sleep mode to respond to the emergency system functions, it will generate high power consumption, and the vehicle emergency system functions (such as turning on the emergency lights) cannot continue to work for a long time, affecting the execution requirements and execution continuity of the vehicle functions under emergency conditions.

[0004] Therefore, the network management of existing vehicles has the problem of poor flexibility and cannot meet the execution requirements and execution continuity of vehicle functions under emergency conditions. Summary of the invention

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0047] Today, the traditional vehicle network management model mainly relies on direct network management strategies, that is, sending unified network management messages to control the electronic control unit (ECU) of the entire vehicle to enter a dormant state to reduce the vehicle's energy consumption. Although this method is effective under normal circumstances, it has significant shortcomings in certain situations:

[0048] In emergency situations, the traditional network management mode will put all ECU modules into a dormant state, which may cause the emergency system to fail to wake up and respond in time. For example, when the vehicle has a main battery failure or other emergency situations, key equipment such as emergency lights and alarm systems cannot work properly in the dormant state of the vehicle, which will reduce the vehicle's safety and emergency response capabilities.

[0049] The traditional network management model adopts a unified management strategy and cannot be flexibly adjusted according to different application scenarios and needs. In some cases, the vehicle may only need to keep some network modules awake. For example, in an emergency situation of an abnormal state, the vehicle only needs to wake up the emergency system to keep working, such as turning on the emergency lights, while other modules can continue to sleep. The traditional network management model cannot achieve the operation of making some modules sleep and other modules awake at the same time.

[0050] Although the direct network management mode can effectively reduce energy consumption by putting the vehicle into sleep mode when the power is cut off, the emergency function cannot be executed when the vehicle enters sleep mode under specific working conditions. If the vehicle exits sleep mode, all vehicle systems and components will be awakened. If only emergency functions are executed when the vehicle is awake, there will be a certain amount of energy waste, and the intelligent potential of the vehicle will not be fully utilized.

[0051] Based on the above problems, the present application provides a network management method, which first detects the state of the vehicle, and then can flexibly and accurately determine the network management mode corresponding to the vehicle's network according to the state of the vehicle. It can wake up the domain controller network related to the vehicle's emergency conditions when the vehicle is in an abnormal state according to the state change of the vehicle, and stop unnecessary network activities through the correct network management mode, so that the vehicle can continue to perform emergency functions based on the correct network mode in an abnormal state, and the network management mode can be implemented without complex adjustments or upgrades to the vehicle's hardware. Thereby, the flexibility of network management can be improved, so that the vehicle can still perform emergency functions normally under emergency conditions, and effectively reduce the overall power consumption of the vehicle and increase the execution time of the vehicle's emergency functions.

[0052] The present application is described below in conjunction with specific embodiments.

[0053] Figure 2 is a schematic diagram of a network management method provided by an embodiment of the present application, such as Figure 2 As shown, the method may include Figure 1 Steps S101 and S102 shown in the figure are described in detail below:

[0054] Step S101, detecting the state of the vehicle.

[0055] In the scenario of the present application, detecting the status of the vehicle may refer to monitoring the current operating status and environmental conditions of the vehicle to facilitate subsequent decisions on whether the vehicle enters or exits a local network management mode and selectively wakes up or sleeps certain electronic control units (ECUs).

[0056] In some embodiments, the gear state of the vehicle can be detected, and specifically, whether the gear state of the vehicle is in the "OFF gear" state is one of the key conditions for determining whether to enter the sleep mode. In the "OFF gear" state, the vehicle is usually in a non-operating state, and network management is required to reduce the power consumption of the vehicle.

[0057] In some embodiments, it is possible to detect whether the vehicle has an emergency driving signal, such as a double flash light signal. When the vehicle is in an emergency state, some key systems or components of the vehicle need to remain in working state, and the working state of these systems can be triggered and maintained by the emergency signal.

[0058] In some embodiments, the local signals of each module inside the vehicle and the signals transmitted through the CAN bus can be detected to determine whether there are signal changes that affect entering sleep. For example, changes in CAN signals such as debug messages, diagnostic messages, and application messages may affect the wake-up requirements of certain modules.

[0059] In some embodiments, it can be determined whether a specific function of the vehicle requires continuous access to the bus. For example, certain diagnostic or monitoring functions of the vehicle may need to keep the network awake in order to obtain and respond to important vehicle status information in a timely manner.

[0060] In some embodiments, the above monitoring operations for the vehicle status can be performed in a certain order. For example, the gear status of the vehicle can be identified first. If the vehicle is in the "OFF gear", the next step of inspection is performed. Then check whether the emergency drive signal of the vehicle is activated. If the emergency signal is activated or valid, the vehicle needs to keep some systems in working state. Then detect the state changes of the local signal and CAN signal of the vehicle to determine whether there are signal changes that require continued network access or maintain the awake state. Finally, based on the detected vehicle status, it can be decided whether the vehicle enters or exits the local network management mode. For modules that meet the conditions, the network management system (also referred to as "system") can selectively maintain its working state, while other modules can enter sleep mode to save energy.

[0061] Through the above methods, this application can accurately detect the vehicle status and reduce the power consumption of the whole vehicle without affecting the emergency response capability of the vehicle. It can also improve the flexibility and adaptability of network management, which helps to maintain the safety and functional reliability of the vehicle in complex and changing emergency situations.

[0062] Step S102: Determine the network management mode corresponding to the network of the vehicle according to the state of the vehicle, so that the vehicle can continue to perform emergency functions based on the correct network mode in an abnormal state.

[0063] It can be understood that since the state of the vehicle in this scenario is used to determine whether to wake up or sleep certain electronic control units of the vehicle, it is possible to accurately determine which network management mode to use to control the corresponding electronic control unit based on the specific state of the vehicle.

[0064] In some embodiments, before executing step S102, the following steps may be performed preferentially:

[0065] First, if it is detected that the vehicle is not in the first network mode, a corresponding network management mode is determined for the vehicle;

[0066] Next, if the vehicle is already in the first network mode, the vehicle is controlled to maintain the first network mode for a preset time period, and a corresponding network management mode is determined for the vehicle after the preset time period.

[0067] In some embodiments, the system may first detect whether the vehicle is already in the first network mode. The first network mode refers to a local network management mode that the vehicle enters under certain conditions, so that only necessary ECU modules remain active to reduce power consumption. The vehicle's status signal, network message and other information can be used to determine whether the current vehicle's network mode meets the system's policy requirements.

[0068] Accordingly, if the detection result indicates that the vehicle is not in the first network mode, the system can determine and switch to the most appropriate network management mode for the vehicle based on the current vehicle status, environmental conditions and specific needs. This mode selection is based on the real-time status information of the vehicle and is intended to ensure that the vehicle can operate in the most optimized manner in non-emergency situations, reducing energy consumption or improving performance.

[0069] Accordingly, if the vehicle is already in the first network mode, the system can control the vehicle to maintain this mode within a preset time. The purpose of setting the preset duration is to ensure that the vehicle can operate stably in the short term and avoid unnecessary energy consumption or system instability that may be caused by frequent mode switching. After the preset duration ends, the system can re-evaluate the status of the vehicle. At this time, the vehicle's network management mode can be determined again based on the vehicle's current operating status, external environment, and functional requirements. This evaluation mechanism can ensure that the vehicle's network management strategy can be dynamically adjusted to adapt to changing usage conditions and vehicle status.

[0070] Through the above methods, this application uses flexible network management strategies to not only improve the adaptability and energy efficiency of the vehicle in different usage scenarios, but also increase the safety and reliability of the vehicle in emergency situations.

[0071] In some embodiments, step S102 may include:

[0072] First, detecting the corresponding relationship between the state of the vehicle and the local network management condition;

[0073] Next, when it is detected that the state of the vehicle meets the local network management condition, the vehicle is controlled to adopt a first network mode of local network communication;

[0074] Finally, when it is detected that the state of the vehicle does not satisfy the local network management condition, the vehicle is controlled to adopt a second network mode of full network communication.

[0075] In some embodiments, the first network mode may be to control the first gateway to disconnect communication, and the second gateway other than the first gateway to maintain communication.

[0076] In some embodiments, the system may first monitor the current state of the vehicle to determine whether it meets the conditions for entering the local network management mode. For example, the conditions for entering the local network management mode may include multiple factors such as the gear state of the vehicle, emergency signals, and vehicle internal signals. For example, when the vehicle is in the "OFF gear" and an emergency function is required, the conditions for entering the local network management may be met.

[0077] Accordingly, when the vehicle status meets the local network management conditions, the system can control the vehicle to enter the first network mode. The first network mode can help the vehicle disconnect certain unnecessary network communications to save energy while retaining only the communications of critical systems. Among them, the first gateway can be the chassis network of the vehicle, and the second gateway can be the smart entry network and body network of the vehicle. For example, the chassis network of the vehicle is disconnected, while the smart entry network and the body network continue to communicate. In this way, the vehicle can quickly enter a low-power state when necessary, extend the working time of emergency equipment, and ensure the normal operation of key functions.

[0078] Accordingly, when the vehicle status no longer meets the local network management conditions, the system can switch the vehicle's network to the second network mode, that is, the full network communication mode. In this second network mode, all network modules resume normal communication to ensure the full functionality and operability of the vehicle. For example, when the vehicle is turned from "OFF gear" to "ON gear", the system will restore the chassis network communication. This second network mode can ensure that when the vehicle is operating normally, the various subsystems can interact normally and provide complete vehicle functions.

[0079] It can be understood that in the first network mode, the chassis network of the vehicle can be disconnected, which means that the chassis-related functions of the vehicle (such as suspension control or tire pressure monitoring) may be temporarily disabled in some cases to reduce unnecessary energy consumption of the vehicle. In the second network mode, the intelligent entry network and the body network of the vehicle can be controlled to maintain communication, which means that the functions related to the vehicle door locks, lighting control, in-vehicle infotainment system, etc. are still working normally, ensuring the basic operation and safety functions of the vehicle in an emergency state.

[0080] Through the above methods, the present application selectively disconnects and maintains network communications, enabling the vehicle to effectively reduce power consumption in emergency situations, extend battery life and the continuous operation time of emergency equipment. The network mode is flexibly adjusted according to the real-time detected vehicle status to improve the adaptability and intelligence level of the system. Under different working conditions, the safety of the vehicle and the normal operation of core functions are guaranteed, while unnecessary resource consumption is reduced, providing a flexible and efficient network management solution for the vehicle in a changing usage environment, which helps to improve the overall performance of the vehicle and user experience.

[0081] In some embodiments, the correspondence between the vehicle status and the local network management condition can be detected by:

[0082] First, detecting the dormant state of the vehicle and the reception state of a local network response signal;

[0083] Next, if the dormant state is activated and the local network response signal is received, detecting a corresponding relationship between the state of the vehicle and a target condition satisfying the influencing network shutdown;

[0084] Finally, if the target condition is met, the vehicle's state of receiving the message from the first gateway is detected, and if the vehicle does not receive the message from the first gateway, the local network management condition is met.

[0085] In some embodiments, the target condition may include: before the vehicle enters the sleep state, there is a local signal that affects the vehicle entering the sleep state, a CAN signal that affects the vehicle entering the sleep state, or at least one of the conditions of a specific function that requires continuous access to the vehicle bus.

[0086] In some embodiments, the system can first detect whether the vehicle has started the sleep state, and monitor whether a local network response signal is received. The start of the sleep state refers to a low-power mode that the vehicle enters when there is no active operation or when all network functions are not required. The local network response signal is a signal sent under specific conditions to wake up or keep certain network modules active.

[0087] Accordingly, if the vehicle has started the sleep state and received a local network response signal, the system can further detect the correspondence between the vehicle and the target conditions that affect the network shutdown. For example, the vehicle needs to request the network to stay awake to support certain key functions, the vehicle needs to respond to specific network messages, and the vehicle needs to continue to send certain network messages to maintain normal communication or monitoring status.

[0088] Specifically, the target condition that the vehicle needs to request the network to remain awake to support certain key functions refers to the situation where the vehicle is in the "OFF gear" state and the modules have not yet entered the bus pre-sleep mode, and the local signal changes of the modules need to continue to access the network and remain awake. In the "OFF gear" state, some functional modules (such as door locks and window controls) may be activated due to user operations, such as local signals involving CAN bus communication, which require the network to remain awake to perform corresponding operations.

[0089] For target conditions where the vehicle needs to respond to specific network messages, when the vehicle is in the "OFF" state, the module has not yet entered the bus pre-sleep mode. If the signals on the CAN bus change and these signals require the module to take action or respond, the network needs to continue to access. For example, when the vehicle is in diagnostic mode or maintenance mode, it may receive debug messages, diagnostic messages, or application messages. Such changes in CAN signals require the module to take corresponding actions or responses, so the network must remain awake.

[0090] For target conditions where the vehicle needs to continuously send certain network messages to maintain normal communication or monitoring status, when the vehicle is in the "OFF" state, some special functions require the module to continuously send messages to continuously inform its own status or maintain a certain status of the receiver. At this time, the network needs to remain awake. For example, some safety systems (such as anti-theft alarms) or monitoring systems (such as remote vehicle status monitoring) need to continuously send status information when the vehicle is in the "OFF" state in order to perform real-time monitoring or response.

[0091] In some embodiments, when the target conditions are met, the system can detect whether the vehicle receives a message from the first gateway. The first gateway refers to a specific vehicle subsystem network, such as whether the chassis network is communicating. If no message from the first gateway, that is, a message related to the chassis network, is received, it means that the network can be disconnected to enter the local network management mode, ensuring that certain network communications are selectively closed or restricted to reduce energy consumption without affecting the core functions of the vehicle.

[0092] As an example, in some cases, the vehicle needs to keep the network awake to ensure the continuous operation of vehicle safety functions (such as anti-theft systems) or infotainment systems. When the vehicle is in certain diagnostic or maintenance modes, it needs to respond to specific diagnostic messages. In some monitoring functions (such as remote vehicle status monitoring), the vehicle needs to continue to send status information to maintain the effectiveness of monitoring.

[0093] Through the above methods, through target condition detection and network strategy adjustment, the vehicle can minimize energy consumption while meeting emergency and basic functions. Ensuring that key functions can operate normally when needed, especially in complex and emergency environments, enhances the overall safety of the vehicle. Flexible detection and management mechanisms enhance the intelligence level of vehicle systems, enabling them to adapt to different usage scenarios and needs.

[0094] In some embodiments, the correspondence between the vehicle status and the local network management condition can be detected by:

[0095] First, if it is detected that the vehicle does not start the dormant state, the local network management condition is not met;

[0096] Then, if the dormant state is activated, the corresponding relationship between the state of the vehicle and the target condition is detected, and if the target condition is not satisfied, the local network management condition is not satisfied;

[0097] Next, if the target condition is met, detecting a reception status of the vehicle to the local network response signal, and if the vehicle fails to receive the local network response signal, the local network management condition is not met;

[0098] Finally, if the local network response signal is received, the vehicle's state of receiving the message from the first gateway is detected. If the message from the first gateway is not received, the local network management condition is not met.

[0099] In some embodiments, the system can first check whether the vehicle has entered a dormant state. If the vehicle has not started the dormant state, the vehicle does not meet the local network management conditions. It can be understood that the goal of local network management is to keep the network of some systems and modules of the vehicle awake after the vehicle enters the dormant state, so that the vehicle can still perform corresponding functions normally based on some modules that remain awake under emergency conditions, and shut down some networks to reduce unnecessary energy consumption and extend the time required to execute functions. Therefore, the vehicle entering a dormant state is a prerequisite for implementing local network management.

[0100] In some embodiments, if the vehicle has entered the dormant state, the system can further check whether the vehicle meets the various target conditions mentioned above. If the vehicle does not meet any target conditions, it means that the vehicle also does not meet the conditions for entering the local network management, and no additional network activity is required.

[0101] In some embodiments, if the vehicle meets the target condition, the system can detect whether the vehicle receives a local network response signal, which is a signal used to confirm that certain network modules need to remain active. If no response signal is received, the local network management condition is not met, indicating that there is no external demand to maintain the activity of certain modules.

[0102] Correspondingly, if a local network response signal is received, the system can further detect whether a message from the first gateway (eg chassis network) is received. If no message from the first gateway is received, it means that the vehicle can enter the local network management condition, indicating that the vehicle can shut down certain networks to reduce energy consumption.

[0103] As an example only, in actual applications, the vehicle enters a dormant state when there is no active operation. The vehicle detects a door lock operation in the dormant state, indicating that the vehicle's state meets the target condition "the vehicle still needs to request the network to stay awake", and also detects a vehicle diagnostic information update, indicating that the vehicle's state meets the target condition "continue to send network messages". Then, the system can receive a local network response signal from the body network, indicating that communication needs to continue. If no message is received to the chassis network, the chassis network is allowed to sleep while other networks remain active.

[0104] The vehicle may include a first area corresponding to the driving area, and a second area outside the driving area.

[0105] In some embodiments, the local network response signal corresponding to the first area is an emergency driving signal, and the local network response signal corresponding to the second area is an indication signal indicating that the first area enters or exits the first network mode.

[0106] The first area usually refers to the area directly related to driving, including all systems and equipment in the cockpit. The network management of this area involves functions related to driving safety and operation. Since my country's traffic rules adopt right-hand driving, the driving area of ​​most vehicles is set on the left side of the vehicle, so the first area can also be called the "left domain".

[0107] Among them, the emergency drive signal is a signal used to trigger or maintain the key functions of the first area. For example, when the vehicle is in an emergency state, the driving area needs to be kept working first to ensure that the driver can control the vehicle and respond to emergencies in time. The emergency signal ensures that in an emergency situation, the key systems of the first area (such as steering and braking) remain active to ensure the driver's operation and safety.

[0108] The second area refers to other parts of the vehicle that are not directly related to driving operations, which may include the vehicle body, entertainment system, rear seat controls, etc. Since the second area is outside the first area, the second area may include the "rear area" and "right area" of the vehicle.

[0109] The local network response signal is used as an indication signal to indicate that the first area enters or exits the first network mode. The indication signal is used to determine the network status of the first area to determine the network activity of the second area. For example, when the first area enters sleep or low power mode, the second area can also adjust its network activity accordingly. Through the indication signal, the vehicle can dynamically coordinate the network activities of different areas to achieve overall energy consumption optimization and functional coordination.

[0110] It should be noted that since the first area is the driving area of ​​the vehicle, when the system executes the method of the present application, it will give priority to judging whether the first area enters or exits the local network management mode. After determining that the first area enters the first network mode of local network management, it will judge whether other second areas adopt the local network management mode.

[0111] As an example only, when the vehicle is driving at high speed, an emergency situation suddenly occurs and the driver triggers the emergency mode (such as emergency braking). The emergency drive signal can activate the network of the first area to ensure the normal operation of all driving-related systems and ensure that the driver can fully control the vehicle in an emergency. Correspondingly, when the vehicle enters sleep mode at a low speed and the first area does not need all functions to remain active, the second area confirms the state of the first area through an indication signal, and then enters the corresponding low-power mode to reduce unnecessary energy consumption in the second area and extend the battery life.

[0112] Through the above methods, the network management of vehicle area division can reduce unnecessary network activities and achieve higher energy efficiency while meeting safety requirements. The system can flexibly adjust network activities according to the needs and status of different areas to improve the overall intelligent management level of the vehicle. While ensuring driving safety, it can optimize energy consumption and improve the adaptability and performance of the vehicle in different usage scenarios.

[0113] In some embodiments, the method of the present application may further include:

[0114] First, when it is detected that the state of the vehicle in the first network mode no longer satisfies the local network management condition, the network of the vehicle is controlled to exit the first network mode and adopt the second network mode;

[0115] Next, when it is detected that the state of the vehicle already in the second network mode satisfies the local network management condition, the network of the vehicle is controlled to exit the second network mode and adopt the first network mode.

[0116] In some embodiments, the system may continuously monitor the state of the vehicle, and when it is detected that the state of the vehicle no longer meets the local network management conditions, the vehicle is controlled to exit the first network mode. For example, some signal changes of the vehicle no longer require the network to remain awake, and the emergency drive signal or indication signal indicates that the current network state does not need to be maintained.

[0117] When the partial network management conditions are no longer met, the system can control the vehicle to exit the first network mode of partial network management and switch to the second network mode, i.e., the full network management mode, to restore normal communication of all network modules. By exiting the first network mode, the vehicle restores full network functions, ensuring that the vehicle can provide full operability and functionality when energy consumption optimization is not required.

[0118] In some embodiments, when it is detected that the vehicle in the second network mode meets the local network management condition, the network management mode of the vehicle needs to be switched, for example, when an emergency function signal or other required network activity that the vehicle needs to maintain is detected to be reduced, or a signal change of a target condition indicates that a low power consumption mode can be entered.

[0119] When the partial network management conditions are met, the system can control the vehicle to exit the second network mode and switch to the first network mode, namely the partial network management mode, so that the vehicle only keeps the necessary network modules active to reduce energy consumption. By entering the first network mode, the vehicle can significantly reduce energy consumption without affecting key functions, thereby extending battery life and the operating time of emergency equipment.

[0120] As an example only, when the vehicle stops driving and the driver restarts the vehicle or starts certain operations, causing the signal state to change, local management is no longer needed. At this time, the vehicle network returns to full network mode, and all functions operate normally to support the driver's operational needs. Correspondingly, when the vehicle enters a long-term parking state, the driver turns off most of the vehicle's functions and only needs to maintain basic monitoring and safety functions. At this time, the vehicle network switches to local management mode, limiting unnecessary network activities and reducing energy consumption.

[0121] It can be seen from this that the embodiment of the present application first detects the status of the vehicle, and then can flexibly and accurately determine the network management mode corresponding to the vehicle's network based on the status of the vehicle. It can wake up the domain controller network related to the vehicle's emergency conditions when the vehicle is in an abnormal state according to the state changes of the vehicle, and stop unnecessary network activities through the correct network management mode, so that the vehicle can continue to perform emergency functions based on the correct network mode in an abnormal state, thereby improving the flexibility of network management, allowing the vehicle to still perform emergency functions normally under emergency conditions, and effectively reducing the overall power consumption of the vehicle to increase the execution time of the vehicle's emergency functions.

[0122] See also Figure 2 , Figure 2 This is a schematic diagram of a network management mode provided in an exemplary embodiment of the present application. Figure 2 Describe the contents in detail.

[0123] When the vehicle is not enabled or the network is inactive, the system enters bus sleep mode to reduce the energy consumption of the vehicle. When the vehicle is in normal operation, the vehicle's domain controller manages the "local area network" status to achieve efficient network operation and energy saving.

[0124] Figure 2 The LAN=0 mark means that the current domain controller is not in the local network management state, and the domain controller maintains normal communication with all networks. When the conditions for entering the local area network are met, the state of the domain controller will switch to the local network management mode, that is, the mark is LAN=1, indicating that the domain controller is in the local network management state and may stop communicating with non-essential networks to save energy.

[0125] In some embodiments, when the system detects duplicate messages in the network or certain conditions are triggered, the system may enter the duplicate message mode to ensure network stability and accuracy. When all local network management conditions are invalid, the system will enter the preparation sleep mode to prepare for the vehicle to enter the bus sleep mode.

[0126] In some embodiments, when it is detected that all target conditions for entering local network management are invalid, the system can exit the local network management mode and switch to normal operation or enter the sleep preparation mode. When any target condition is valid, the system can remain in the local network management mode (local area network = 1) to optimize the use of network resources.

[0127] Figure 2 By describing the vehicle's network state transitions and conditional logic, it can reflect how the domain controllers in various areas of the vehicle monitor network status and signals to optimize network management and reduce vehicle energy consumption. The above entire process can ensure efficient management and operation of the vehicle network under different operating conditions.

[0128] See also Figure 3 , Figure 3 1 is a schematic diagram of detecting the switching of the network management mode of the first area provided in an exemplary embodiment of the present application, specifically the process of the network management mode of the first area controller of the vehicle, that is, the left domain controller. The process of switching the network management mode of the vehicle will be described in detail below.

[0129] In some embodiments, when the vehicle meets all of the following conditions, the left domain controller can enter the first network mode of local network management:

[0130] (1) Detection of OFF gear: The vehicle is in a stopped state and the controller detects that the vehicle gear is OFF;

[0131] (2) Emergency drive signal is valid: The emergency drive signal is received, such as the hard-wire signal triggering of the double flash lights.

[0132] (3) All target conditions are invalid: except for the emergency drive signal, other signal conditions, such as local signal changes, CAN signal changes, and special function requirements, are invalid.

[0133] (4) Connection channel restriction: Only network management messages from the right domain or the back domain are received, and no other network management messages are received.

[0134] It can be understood that in this case, the signal position of the left domain local area network is set to 0x510_3.1=1, and the network ID can be set according to the actual situation, indicating that the local network management state has been entered. In the local network management mode, the left domain maintains the communication between the intelligent entry network and the vehicle body network, and stops sending messages on other network channels.

[0135] In some embodiments, the left domain controller may exit the first network mode of local network management and return to the second network mode of full network communication under any of the following conditions:

[0136] (1) ON gear is detected: The vehicle is in the starting state and the gear is switched from OFF gear to ON gear.

[0137] (2) Invalid emergency drive signal: No valid emergency drive signal is received.

[0138] (3) Any target condition is valid: Other signal conditions, such as local signal change, CAN signal change, and special function requirements become valid.

[0139] (4) Receiving other network management messages: In addition to the right domain, other network management messages are received.

[0140] In the above case, the signal position of the left domain local area network can be set to 0x510_3.1=0, and the left domain network of the vehicle exits the first network mode of local network management and resumes the second network mode of full network communication.

[0141] like Figure 3 As shown, the specific steps are as follows:

[0142] Step 201 , check whether the first network mode has been entered, if yes, proceed to step 202 , if no, proceed to step 208 .

[0143] Step 202: Maintain the first network mode, disconnect the first gateway from communication, and maintain communication with other gateways, and proceed to step 203. That is, currently maintain the local network management mode, stop chassis network message sending, and maintain intelligent network communication.

[0144] Step 203, detect whether the vehicle is in the OFF gear, if so, proceed to step 204, if not, proceed to step 207, and exit the first network mode.

[0145] Step 204, check whether all target conditions are invalid, if yes, proceed to step 205, if no, proceed to step 207, exit the first network mode.

[0146] Step 205 , detect whether the emergency driving signal is received, if yes, proceed to step 206 , if no, proceed to step 207 .

[0147] Step 206, detect whether the first gateway receives the message, if yes, proceed to step 207, exit the first network mode, if no, return to step 202, continue to maintain the second gateway communication.

[0148] Step 207: exit the first network mode.

[0149] Step 208 , detect whether the vehicle is in the OFF gear, if so, proceed to step 209 , if not, proceed to step 213 , and the vehicle enters the normal working mode.

[0150] Step 209, detect whether the emergency driving signal is received, if yes, proceed to step 210, if no, proceed to step 212, retain the original direct network management logic, that is, maintain the second network mode.

[0151] Step 210, check whether all target conditions are invalid, if yes, proceed to step 211, if no, proceed to step 212, and maintain the second network mode.

[0152] Step 211, detect whether the first gateway receives the message, if so, proceed to step 212, maintain the second network mode, if not, return to step 202, and adopt the first network mode.

[0153] Step 212: Maintain the second network mode.

[0154] Step 213: Perform normal working mode.

[0155] In this way, the first area of ​​the vehicle can optimize network communications under specific conditions to improve energy efficiency and emergency response capabilities, ensuring flexible adaptation and energy consumption optimization of the vehicle under different working conditions.

[0156] See also Figure 4 , Figure 4 1 is a schematic diagram of detecting the switching of the network management mode of the second area provided in an exemplary embodiment of the present application, specifically the process of the network management mode of the second area controller of the vehicle, that is, the right / rear domain controller. The process of switching the network management mode of the vehicle will be described in detail below.

[0157] In some embodiments, the second regional controller, i.e., the right / rear domain controller, may enter the first network mode of local network management when the following conditions are simultaneously met:

[0158] (1) Detection of OFF gear: The vehicle is in a stopped state, and the right / rear domain controller detects that the vehicle gear position is OFF.

[0159] (2) The left domain local area network signal position is 0x510_3.1=1: indicating that the left domain is already in the local network management mode.

[0160] (3) All target Tianjian are invalid: It means that the vehicle currently does not need additional network activities, such as local signal changes, CAN signal changes, and special function requirements.

[0161] (4) Only left domain network management messages received: Indicates that the vehicle does not receive other network management messages from the right / rear domain.

[0162] In this case, the signal position of the right / rear domain local area network is set to 0x511_3.1=1, indicating that the local network management state has been entered. The right / rear domain maintains the communication between the smart entry network and the body network, but stops sending messages on other network channels and stops forwarding messages between the smart entry network and the body network.

[0163] In some embodiments, the right / rear domain controller may exit the local network management mode when any of the following conditions are met:

[0164] (1) ON gear is detected: the vehicle is in the starting state.

[0165] (2) The left domain local area network signal position is 0x510_3.1=0: the left domain exits the local network management mode.

[0166] (3) Any one of the target conditions is valid: it means that the vehicle currently requires additional network activity.

[0167] (4) Receiving other network management messages: Indicates that in addition to the left domain, other network management messages from the right / back domain will also be received.

[0168] In this case, the signal position of the right / rear domain local area network is set to 0x511_3.1=0, the first network mode of local network management is exited, and the second network mode of full network communication is restored.

[0169] like Figure 4 As shown, the specific steps are as follows:

[0170] Step 301 , check whether the first network mode has been entered, if yes, proceed to step 302 , if no, proceed to step 308 .

[0171] Step 302: Maintain the first network mode, disconnect the first gateway from communication, and maintain communication with other gateways, and proceed to step 303. That is, currently maintain the local network management mode, stop chassis network message sending, and maintain intelligent network communication.

[0172] Step 303, check whether the vehicle is in the OFF gear, if so, proceed to step 304, if not, proceed to step 307, and exit the first network mode.

[0173] Step 304, check whether all target conditions are invalid, if yes, proceed to step 305, if no, proceed to step 307, exit the first network mode.

[0174] Step 305 , detect whether the second gateway has received the message, that is, detect whether the vehicle's intelligent network has received the message 0x510_3.1=1, if yes, proceed to step 306 , if no, proceed to step 307 .

[0175] Step 306, detect whether the first gateway receives the message, if yes, proceed to step 307, exit the first network mode, if no, return to step 302, continue to maintain the second gateway communication.

[0176] Step 307: exit the first network mode.

[0177] Step 308 , detect whether the vehicle is in the OFF gear, if so, proceed to step 309 , if not, proceed to step 313 , and the vehicle enters the normal working mode.

[0178] Step 309, detect whether the first gateway receives the message, that is, detect whether the intelligent network receives the message 0x510_3.1=1, if yes, go to step 310, if not, go to step 312, retain the original direct network management logic, that is, maintain the second network mode.

[0179] Step 310, check whether all target conditions are invalid, if yes, proceed to step 311, if no, proceed to step 312, and maintain the second network mode.

[0180] Step 311, detect whether the first gateway receives the message, if so, proceed to step 312, maintain the second network mode, if not, return to step 302, and adopt the first network mode.

[0181] Step 312: Maintain the second network mode.

[0182] Step 313: Perform normal working mode.

[0183] Through the above methods, the present application can provide a flexible network management mechanism for the domain controllers in various areas of the vehicle, achieve energy efficiency optimization and functional guarantee of the entire vehicle, and extend the normal working time of key modules in emergency situations.
