Detailed Implementation

[0042] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 1 This is a schematic diagram of the architecture of the electronic and electrical system 10 according to an embodiment of this application. The electronic and electrical system 10 includes a first device 11, a second device 12, a first communication link 21, and a second communication link 22. The first communication link 21 communicatively connects the first device 11 and the second device 12, and the second communication link 22 communicatively connects the first device 11 and the second device 12. The first device 11 and the second device 12 can communicate with each other via the first communication link 21; or the first device 11 and the second device 12 can communicate with each other via the second communication link 22; or the first device 11 and the second device 12 can communicate with each other via the first communication link 21 and the second communication link 22.

[0044] When the electronic and electrical system 10 is in different operating states, the first device 11 and the second device 12 can communicate using different communication links. For example, when the first communication link 21 between the first device 11 and the second device 12 fails, the first device 11 and the second device 12 can communicate through the second communication link 22. Alternatively, when the first communication link 21 cannot support the communication requirements, the first device 11 and the second device 12 can communicate through the second communication link 22; or the first device 11 and the second device 12 can communicate through both the first communication link 21 and the second communication link 22 to better meet the transmission requirements between the first device 11 and the second device 12. This improves the reliability of the vehicle's electronic and electrical system 10.

[0045] Among them, the situation in which the first communication link 21 cannot support the transmission requirements may be, for example, but not limited to, the transmission resources of the first communication link 21 being insufficient to meet the transmission requirements between the first device 11 and the second device 12.

[0046] Optionally, the communication type of the first communication link 21 can be one of Ethernet communication, Controller Area Network (CAN) bus, fiber optic communication, WiFi communication, or Bluetooth communication.

[0047] Optionally, the communication method of the second communication link 22 is one of Ethernet communication, CAN communication, fiber optic communication, WiFi communication, and Bluetooth communication.

[0048] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0049] like Figure 1 In some possible embodiments, the communication type of the first communication link 21 and the second communication link 22 is the same.

[0050] For example, the first communication link 21 and the second communication link 22 can both be Ethernet communication; or the first communication link 21 can be CAN communication and the second communication link 22 can be CAN communication, etc. In such a scheme, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type. It can be understood that in such a scheme, the first communication link 21 and the second communication link 22 can form a ring loop, creating a path redundancy architecture. Furthermore, since the first communication link 21 and the second communication link 22 use the same communication type, switching between communication links can be performed more conveniently, simplifying the stability of the electronic and electrical system 10 and facilitating control.

[0051] Optional, such as Figure 1 The first device 11 and the second device 12 can be configured to be independent and mutually redundant. In a vehicle, the first device may include a cross-domain computing controller, and the second device may include a right-area controller. The cross-domain computing controller and the right-area controller adopt an inter-domain redundancy design. Both the cross-domain computing controller and the right-area controller can include power control functions, steering & braking functions, body control functions, and chassis control functions. When either of the two domain controllers malfunctions, the power control functions, steering & braking functions, body control functions, and chassis control functions can still operate normally.

[0052] Among them, such as Figure 2As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13. The third device 13 is connected to the first communication link 21 and is located between the first device 11 and the second device 12. Communication between the devices can be achieved through a loop formed by the first communication link 21 and the second communication link 22. For example, when a communication failure occurs between the first device 11 and the third device 13 in the first communication link 21, the third device 13 can communicate with the second device 12 via the link between the second device 12 and the third device 13 through the first communication link 21; or, the third device 13 can also communicate with the first device 11 via the second device 12 through the second communication link 22. As another example, when a communication failure occurs between the second device 12 and the third device 13 in the first communication link 21, the third device 13 can communicate with the first device 11 via the link between the first device 11 and the third device 13 through the first communication link 21; or, the third device 13 can also communicate with the second device 12 via the first device 11 through the second communication link 22.

[0053] It is understood that there are redundant communication paths between the two devices in the loop formed by the first communication link 21 and the second communication link 22. This ensures that if one communication path between the two devices fails, communication between the two devices can still be achieved through the other communication path.

[0054] like Figure 3 As shown, in some other possible implementations, the electronic and electrical system further includes a fourth device 14, which is connected to the second communication link 22 and located between the first device 11 and the second device 12. Communication between the devices can be achieved through a loop formed by the first communication link 21 and the second communication link 22. For example, when a communication failure occurs between the first device 11 and the fourth device 14 in the second communication link 22, the fourth device 14 can communicate with the second device 12 via the link between the second device 12 and the fourth device 14; or, the fourth device 14 can also communicate with the first device 11 via the second device 12 and the first communication link 21. Again, for example, when a communication failure occurs between the second device 12 and the fourth device 14 in the second communication link 22, the fourth device 14 can communicate with the first device 11 via the link between the first device 11 and the fourth device 14; or, the fourth device 14 can also communicate with the second device 12 via the first device 11 and the first communication link 21.

[0055] It is understood that the first communication link 21 and the second communication link 22 form a ring communication network. Other devices can also be connected to the first communication link 21 and the second communication link 22, and there is redundant communication path between any two devices connected to the first communication link 21 or the second communication link. Equipping a vehicle with such a ring communication network can improve the reliability of communication between various devices in the vehicle's electronic and electrical system.

[0056] In the vehicle, the first device 11 may include a cross-domain computing controller, and the second device 12 may include a right area controller. Additionally, the vehicle 100 includes a front area controller, a rear area controller, a driving domain controller, and a cockpit domain controller. These controllers can be interconnected via Ethernet, CAN bus, and LIN bus to achieve multi-terminal, multi-path interconnection. Even if one of the Ethernet, CAN bus, or LIN bus connections between any two domain controllers is broken, a connection can still be established through the remaining Ethernet, CAN, or LIN bus connections. Alternatively, the connection to the disconnected domain controllers can be established through indirect connections with other domain controllers, thereby achieving path redundancy and bus redundancy between domain controllers.

[0057] like Figure 4 As shown, in some other possible embodiments, the communication types of the first communication link 21 and the second communication link 22 are different.

[0058] For example, the first communication link 21 can be Ethernet communication and the second communication link 22 can be CAN communication; or the first communication link 21 can be WiFi communication and the second communication link 22 can be fiber optic communication, etc. In such a scheme, the first communication link 21 and the second communication link 22 are redundant paths of different communication types, which can be constructed as bus redundancy. When the first communication link 21 fails or cannot support the transmission requirements, the second communication link 22 can be used to realize communication between the first device 11 and the second device 12.

[0059] It is understandable that in such a scheme, the first communication link 21 and the second communication link 22 can form different types of communication redundancy. When the first communication link 21 fails or cannot support the transmission requirements, the second communication link 22 can be used to realize communication between the first device 11 and the second device 12.

[0060] In addition, such as Figure 5 As shown, in some possible implementations, the electronic and electrical system 10 may also include a third device 13, which is connected to the first communication link 21 and located between the first device 11 and the second device 12. Communication between the devices can be achieved through the loop formed by the first communication link 21 and the second communication link 22.

[0061] like Figure 6 As shown, in some other possible implementations, the electronic and electrical system may also include a fourth device 14 connected to the second communication link 22, located between the first device 11 and the second device 12. Communication between the devices can be achieved through a loop formed by the first communication link 21 and the second communication link 22.

[0062] like Figure 7 As shown, in some possible embodiments, the electronic and electrical system 10 further includes a third communication link 23, wherein the third communication link 23 communicatively connects the first device 11 and the second device 12, and the third communication link 23 is used for communication between the first device 11 and the second device 12. The first device 11 and the second device 12 communicate with each other via at least one of the first communication link 21, the second communication link 22, and the third communication link 23.

[0063] For example, when the first communication link 21 between the first device 11 and the second device 12 fails, the first device 11 and the second device 12 can communicate through the second communication link 22 and / or the third communication link 23. As another example, when the first communication link 21 cannot support the communication requirements, the first device 11 and the second device 12 can communicate through the second communication link 22; or the first device 11 and the second device 12 can communicate through the third communication link 23; or the first device 11 and the second device 12 can also communicate through at least two of the first communication link 21, the second communication link 22, and the third communication link 23 to better meet the transmission requirements between the first device 11 and the second device 12. This can improve the reliability of the vehicle's electronic and electrical system 10.

[0064] In this application, a redundant communication link is provided between the first device 11 and the second device 12. This solution can avoid communication abnormalities between the first device 11 and the second device 12 due to communication link failure or inability of the communication link to meet communication requirements.

[0065] Among them, such as Figure 8As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13. The third device 13 is connected to the first communication link 21 and the third communication link 23, and is located between the first device 11 and the second device 12. Communication between the devices can be achieved through the redundant design of the first communication link 21, the second communication link 22, and the third communication link 23. For example, when a communication failure occurs between the first device 11 and the third device 13 in the first communication link 21, the third device 13 can communicate with the second device 12 via the link between the second device 12 and the third device 13 through the first communication link 21; or, the third device 13 can also communicate with the first device 11 via the second device 12 through the second communication link 22; or, the third device 13 can also communicate with the second device 12 via the link between the second device 12 and the third device 13 through the third communication link 23; or, the third device 13 can also communicate with the first device 11 via the link between the first device 11 and the third device 13 through the third communication link 23, etc.

[0066] like Figure 9 As shown, in some other possible implementations, the electronic and electrical system 10 further includes a fourth device 14 connected to the second communication link 22, located between the first device 11 and the second device 12. Communication between the devices can be achieved through a redundant design of the first communication link 21, the second communication link 22, and the third communication link 23. For example, when a communication failure occurs between the first device 11 and the fourth device 14 in the second communication link 22, the fourth device 14 can communicate with the second device 12 via the link between the second device 12 and the fourth device 14; or, the fourth device 14 can also communicate with the first device 11 via the second device 12, through the first communication link 21 and / or the third communication link 23.

[0067] Optionally, the communication type of the third communication link 23 can be one of Ethernet communication, CAN communication, fiber optic communication, WiFi communication, or Bluetooth communication. The communication types of the first communication link 21, the second communication link 22, and the third communication link 23 can be set to be different for each other, or at least the same for both.

[0068] like Figure 10As shown, in some possible implementations, the first communication link 21 and the second communication link 22 have the same communication type, while the third communication link 23 has a different communication type than the first communication link 21, constructing a path redundancy and bus redundancy architecture. For example, the first communication link 21 is Ethernet communication, the second communication link 22 is Ethernet communication, and the third communication link 23 is CAN communication; or the first communication link 21 is WiFi communication, the second communication link 22 is WiFi communication, and the third communication link 23 is fiber optic communication, etc. It can be understood that in such a scheme, the first communication link 21 and the second communication link 22 can form a ring loop. The third communication link 23 forms a communication link of a different communication type outside the ring network. In this scheme, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type. When the first communication link 21 fails or cannot support the transmission requirements, the second communication link 22 can be used to realize communication between the first device 11 and the second device 12. When the ring network communication link formed by the first communication link 21 and the second communication link 22 fails or cannot support the transmission requirements, the third communication link 23 can be used to realize the communication between the first device 11 and the second device 12.

[0069] like Figure 11 In other possible implementations, the first communication link 21 and the second communication link 22 have different communication types, while the third communication link 23 has the same communication type as the first communication link 21. For example, the first communication link 21 may be Ethernet communication, the second communication link 22 may be CAN communication, and the third communication link 23 may be Ethernet communication; or the first communication link 21 may be WiFi communication, the second communication link 22 may be fiber optic communication, and the third communication link 23 may be WiFi communication, etc. It can be understood that in such a scheme, the first communication link 21 and the third communication link 23 can form a ring loop. The second communication link 22 forms a communication link of a different communication type outside the ring network, constructing a path redundancy and bus redundancy architecture.

[0070] like Figure 12 As shown, in some possible embodiments, the electronic and electrical system 10 further includes a third communication link 23 and a fourth communication link 24, wherein the third communication link 23 is communicatively connected to the first device 11 and the second device 12 and is used for communication between the first device 11 and the second device 12, and the fourth communication link 24 is communicatively connected to the first device 11 and the second device 12 and is used for communication between the first device 11 and the second device 12.

[0071] The first device 11 and the second device 12 communicate with each other through at least one of the first communication link 21, the second communication link 22, the third communication link 23 and the fourth communication link 24.

[0072] For example, when the first communication link 21 between the first device 11 and the second device 12 fails, the first device 11 and the second device 12 can communicate through the second communication link 22, the third communication link 23, and / or the fourth communication link 24. As another example, when the first communication link 21 cannot support the communication requirements, the first device 11 and the second device 12 can communicate through the second communication link 22, the third communication link 23, or the fourth communication link 24; or the first device 11 and the second device 12 can also communicate through at least two of the first communication link 21, the second communication link 22, the third communication link 23, and the fourth communication link 24 to better meet the transmission requirements between the first device 11 and the second device 12. This can improve the reliability of the vehicle's electronic and electrical system 10.

[0073] Among them, such as Figure 13 As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13. The third device 13 is connected to the first communication link 21 and the third communication link 23, located between the first device 11 and the second device 12. Communication between the devices can be achieved through a redundant design of the first communication link 21, the second communication link 22, the third communication link 23, and the fourth communication link 24. For example, when a communication failure occurs between the first device 11 and the third device 13 in the first communication link 21, the third device 13 can communicate with the second device 12 via the link between the second device 12 and the third device 13 through the first communication link 21; or, the third device 13 can also communicate with the first device 11 via the second device 12 through the second communication link 22 and / or the fourth communication link 24; or, the third device 13 can also communicate with the second device 12 via the link between the second device 12 and the third device 13 through the third communication link 23; or, the third device 13 can also communicate with the first device 11 via the link between the first device 11 and the third device 13 through the third communication link 23, etc.

[0074] like Figure 14As shown, in some other possible implementations, the electronic and electrical system 10 further includes a fourth device 14, which is connected to the second communication link 22 and the fourth communication link 24, located between the first device 11 and the second device 12. Communication between the devices can be achieved through a redundant design of the first communication link 21, the second communication link 22, the third communication link 23, and the fourth communication link 24. For example, when a communication failure occurs between the first device 11 and the fourth device 14 in the second communication link 22, the fourth device 14 can communicate with the second device 12 via the link between the second device 12 and the fourth device 14; or, the fourth device 14 can also communicate with the first device 11 via the second device 12 through the first communication link 21 and / or the third communication link 23; or, the fourth device 14 can also communicate with the second device 12 via the link between the second device 12 and the fourth device 14; or, the fourth device 14 can also communicate with the first device 11 via the link between the first device 11 and the fourth device 14, etc.

[0075] Optionally, the communication type of the third communication link 23 can be one of Ethernet communication, CAN communication, fiber optic communication, WiFi communication, or Bluetooth communication. Optionally, the communication type of the fourth communication link 24 can be one of Ethernet communication, CAN communication, fiber optic communication, WiFi communication, or Bluetooth communication. The communication types of the first communication link 21, the second communication link 22, the third communication link 23, and the fourth communication link 24 can be set to be different for each pair, or at least the same for two. A gigabit dual-Ethernet ring network can be used between the first device and the second device, achieving transmission path redundancy with a unique dual-ring topology design. Even if a connection is interrupted, stable signal transmission can still be maintained, interrupted transmission can be resumed, and the link is more optimized.

[0076] like Figure 15As shown, in some possible implementations, the first communication link 21 and the second communication link 22 have the same communication type, the third communication link 23 has a different communication type than the first communication link 21, and the fourth communication link 24 has the same communication type as the third communication link 23. For example, the first communication link 21 is Ethernet communication, the second communication link 22 is Ethernet communication, the third communication link 23 is CAN communication, and the fourth communication link 24 is CAN communication; or the first communication link 21 is WiFi communication, the second communication link 22 is WiFi communication, the third communication link 23 is fiber optic communication, and the fourth communication link 24 is fiber optic communication, etc. It can be understood that in such a scheme, the first communication link 21 and the second communication link 22 can form a loop. The third communication link 23 and the fourth communication link 24 can also form a loop, thus forming a dual-ring network architecture. This constructs a path redundancy and bus redundancy architecture. In such a scheme, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type. When the first communication link 21 fails or cannot support the transmission requirements, the second communication link 22 can be used to realize communication between the first device 11 and the second device 12. When the ring network communication link formed by the first communication link 21 and the second communication link 22 fails or cannot support the transmission requirements, the third communication link 23 and the fourth communication link 24 can be used to realize communication between the first device 11 and the second device 12.

[0077] This allows for the parallel deployment of ring links of different communication types, forming a two-layer ring network. Even if one bus malfunctions and becomes unusable, communication can still be maintained through the parallel other bus, improving the reliability of bus communication. For example, one ring network (a ring network architecture consisting of the first and second communication links) can be a gigabit Ethernet bus; the other ring network (a ring network architecture consisting of the third and fourth communication links) can be a CANFD bus.

[0078] like Figure 16As shown, in some other possible implementations, the communication types of the first communication link 21 and the second communication link 22 are different, the communication type of the third communication link 23 is the same as that of the first communication link 21, and the communication type of the fourth communication link 24 is the same as that of the second communication link 22. For example, the first communication link 21 is Ethernet communication, the second communication link 22 is CAN communication, the third communication link 23 is Ethernet communication, and the fourth communication link 24 is CAN communication; or the first communication link 21 is WiFi communication, the second communication link 22 is fiber optic communication, the third communication link 23 is WiFi communication, and the fourth communication link 24 is fiber optic communication, etc. It can be understood that in such a scheme, the first communication link 21 and the third communication link 23 can form a loop. The second communication link 22 and the fourth communication link 24 can also form a loop, thus forming a dual-ring network architecture. This constructs a path redundancy and bus redundancy architecture.

[0079] In some possible embodiments, the first device 11 may include at least one of a controller, a sensor, and an actuator, and / or the second device 12 may include at least one of a controller, a sensor, and an actuator. By combining the aforementioned path redundancy and / or bus redundancy architecture, stable communication between the first device 11 and the second device 12 can be maintained. Even if one communication link between the first device 11 and the second device 12 fails or cannot support transmission requirements, communication can still be maintained through other communication links, thus maintaining the stability of the electronic and electrical system 10.

[0080] The first device 11 and the second device 12 can be different devices. For example, the first device 11 is a controller and the second device 12 is a sensor; or the first device 11 is a controller and the second device 12 is an actuator, etc., which can realize stable communication between different devices.

[0081] Alternatively, the first device 11 and the second device 12 can be configured as identical devices. For example, the first device 11 can be a controller, and the second device 12 can be a controller; or the first device 11 can be a sensor, and the second device 12 can be a sensor, etc. Furthermore, the first device 11 and the second device 12 can be configured to be independent of each other and serve as backups for each other, forming a device redundancy architecture. Combined with the aforementioned path redundancy and / or bus redundancy architecture, a double redundancy or triple redundancy architecture can be formed.

[0082] In some possible embodiments, the first device 11 is a domain controller, and / or the second device 12 is a domain controller. Combined with the aforementioned path redundancy and / or bus redundancy architecture, stable communication between the first device 11 and the second device 12 can be maintained. Even if one communication link between the first device 11 and the second device 12 fails or cannot support transmission requirements, communication can still be maintained through other communication links, thus maintaining the stability of the electronic and electrical system 10.

[0083] The first device 11 and the second device 12 can be used to perform the same function. For example, the first device 11 can be used to perform a first function, and the second device 12 can also be used to perform the first function. The first device 11 and the second device 12 are redundant. When the first device 11 fails or cannot support business requirements, the first function can be performed through the second device 12.

[0084] The first device 11 and the second device 12 can be configured to be independent of each other and serve as backups for each other, forming a device redundancy architecture. Combined with the aforementioned path redundancy and / or bus redundancy architecture, a double redundancy or triple redundancy architecture can be formed.

[0085] The first device 11 and the second device 12 can employ an inter-domain redundancy design. The first device 11 and the second device 12 belong to different functional domains. For example, the first device 11 and the second device 12 can be different domain controllers. At least one of the first device 11 and the second device 12 can include power control functions, steering & braking functions, body control functions, and chassis control functions. When either of the two domain controllers malfunctions, the power control functions, steering & braking functions, body control functions, and chassis control functions can still operate normally.

[0086] For example, the first device 11 is a cross-domain computing controller, and the second device 12 is a right-area controller. A braking network link 25 can be connected between the first device 11 and the second device 12. The braking network link 25 can be configured to connect to signals such as brakes and brake pedals. In addition, a power network link 26 can be connected between the first device 11 and the second device 12. The power network link 26 can be configured to connect to signals such as throttle and powertrain.

[0087] In some possible embodiments, the first device 11 is configured to perform a first function, and the second device 12 is configured to perform the first function when the first device 11 is in a first state. When a single device is in the first state, the other can take over control, ensuring the reliable operation of safety-related functions such as parking brake and collision unlocking, greatly improving safety and stability. The first device 11 and the second device 12 can be configured to be independent and serve as backups for each other, forming a device redundancy architecture. Combined with the aforementioned path redundancy and / or bus redundancy architecture, this forms a double-redundancy or triple-redundancy architecture.

[0088] The first state includes a fault state, or a state in which the first device 11 cannot meet the business requirements on its own. This is so that when a single device fails or cannot meet the requirements, another device can take over or multiple devices can operate together to further improve the stability of the electronic and electrical system 10.

[0089] The first function may include at least one of the following: power control function, steering function, braking function, body control function, and chassis control function. This is to maintain the control functions, steering function, braking function, body control function, and chassis control function of the electronic and electrical system 10.

[0090] In some possible embodiments, the first device 11 can be the first domain controller of the vehicle, and the second device 12 can be the cross-domain computing controller of the vehicle to maintain stable vehicle operation. The first domain controller can be a driving domain controller, a cockpit domain controller, a right area controller, a front area controller, and a rear area controller, etc., and can achieve stable communication between the cross-domain computing controller and the driving domain controller, between the cross-domain computing controller and the cockpit domain controller, between the cross-domain computing controller and the right area controller, between the cross-domain computing controller and the front area controller, or between the cross-domain computing controller and the rear area controller through the aforementioned path redundancy links and / or bus redundancy harnesses.

[0091] In some possible embodiments, the electronic and electrical system 10 further includes a third device 13 connected to the first communication link 21, located between the first device 11 and the second device 12. The third device 13 may include at least one of a controller, a sensor, and an actuator; alternatively, the third device 13 may also be a front area controller of the vehicle.

[0092] In some embodiments, the electronic and electrical system 10 further includes a fourth device 14 connected to the second communication link 22, located between the first device 11 and the second device 12. The fourth device 14 may include at least one of a controller, a sensor, and an actuator. Alternatively, the fourth device 14 may be a rear area controller of the vehicle.

[0093] like Figure 17In some possible embodiments, the first device 11 can be a cross-domain computing controller, the second device 12 can be a right area controller, the third device 13 can be a rear area controller, and the fourth device 14 can be a front area controller. A first communication link 21 connects the cross-domain computing controller, the rear area controller, and the right area controller; a second communication link connects the cross-domain computing controller, the front area controller, and the right area controller; a third communication link connects the cross-domain computing controller, the rear area controller, and the right area controller; and a fourth communication link connects the cross-domain computing controller, the front area controller, and the right area controller. The first communication link can have the same communication type as the second communication link, the third communication link can have the same communication type as the fourth communication link, and the first communication link can have a different communication type than the third communication link.

[0094] In addition, the electronic and electrical system 10 may also include a fifth device 15 and a sixth device 16. The first device, the fifth device 15 and the sixth device 16 can be connected to form a ring network redundancy architecture through a communication link. The fifth device 15 can be an intelligent driving domain controller and the sixth device 16 can be a cockpit domain controller. The cross-domain computing controller, the intelligent driving domain controller and the cockpit domain controller can be connected to form a ring network architecture through a communication link.

[0095] Figure 17 This is a schematic diagram of the path redundancy and bus redundancy structure of a triple redundancy architecture based on domain controllers according to the present invention. The present invention adopts a dual-ring network communication link and achieves transmission path redundancy with a unique dual-ring topology design. Even if the connection in one domain is interrupted, the communication connection between domain controllers can still be achieved through other paths, maintaining stable signal transmission, allowing for resumed transmission from interrupted points, and optimizing the link.

[0096] The cross-domain computing controller and the front area controller can communicate via Ethernet path. If the Ethernet path fails and direct communication via Ethernet is not possible, communication between the cross-domain computing controller and the back area controller can still be achieved through the Ethernet connection between the cross-domain computing controller and the back area controller, and then through the Ethernet bridge of the back level.

[0097] Furthermore, a gigabit Ethernet bus can be used between the cross-domain computing controller and the front area controller, and can be deployed in parallel with the CAN bus, Flexible Data Rate CAN bus (CANFD), or Local Interconnect Network (LIN) to form a two-layer ring network and achieve bus redundancy. The cross-domain computing controller, right area controller, front area controller, rear area controller, intelligent driving domain controller, and cockpit domain controller are interconnected via Ethernet, CAN bus, CANFD bus, and LIN bus. Even if one of the Ethernet / CAN / LIN bus connections between any two domain controllers is broken, a connection can still be established through the parallel, unbroken Ethernet / CAN / CANFD / LIN buses.

[0098] In addition, the first device 11 may include at least one of the following: power controller 101, steering & braking controller 102, body controller 103, and chassis controller 104. The second device may be the same as the first device. The first device and the second device are independent of each other. That is, the first device and the second device can communicate with other components equally. The first device and the second device are backups for each other. When the first device fails, the second device can be used to replace the first device. When the second device fails, the first device can be used to replace the second device.

[0099] This invention proposes a multi-redundancy architecture based on domain controllers. This redundancy architecture, with at least two communication links between the first and second devices, allows critical vehicle subsystems to be deployed simultaneously on two independent domain controllers, serving as backups for each other. The triple redundancy architecture based on domain controllers sets up the vehicle's gigabit-level Ethernet bus and CANFD bus in parallel, forming a two-layer ring network.

[0100] In some specific examples of the present invention Figure 18 This is a schematic diagram of the inter-domain redundancy structure of a triple redundancy architecture based on domain controllers, which adopts an AMP architecture (asymmetric multi-processing) with core-sharing deployment. One system runs on both the first and second devices, ensuring functional safety through dual-core lockstep computation. By drawing biomimetic inspiration from the octopus heart, it innovatively deploys safety-critical subsystems simultaneously on two independent domain controllers, serving as backups for each other.

[0101] Figure 18The cross-domain computing controller and the right area controller employ an inter-domain redundancy design. Both controllers include power control, steering & braking, body control, and chassis control functions. If either controller fails, these functions will continue to operate normally. In the event of a single controller failure, the other can take over control, ensuring reliable operation of safety-related functions such as parking brake and collision unlocking, significantly improving safety and stability.

[0102] The communication types of each communication link in this application are not limited to the examples in the above embodiments. The types and functions of each device in this application are not limited to the examples in the above embodiments.

[0103] The present invention also provides a vehicle 100, including the aforementioned electronic and electrical system 10. The vehicle 100 of the present invention can simultaneously deploy safety-critical subsystems on two independent domain controllers, serving as backups for each other. Combined with the aforementioned dual-ring network architecture, this forms a three-layer redundancy. In the event of a single controller failure, the other can take over control. In the event of a communication link failure, communication can be maintained through redundant communication links, ensuring that safety-related functions such as parking brake and collision unlocking still operate reliably, greatly improving the safety and stability of the system.
