DETAILED DESCRIPTION

[0042] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0043] like Figure 1 , Figure 1 Schematic diagram of the architecture of an electronic and electrical system 10 involved in an embodiment of the present 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, wherein the first communication link 21 is communicatively connected to the first device 11 and the second device 12, and the second communication link 22 is communicatively connected to the first device 11 and the second device 12. The first device 11 and the second device 12 can communicate through the first communication link 21; or 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 first communication link 21 and the second communication link 22.

[0044] When the electronic and electrical system 10 is in different operating states, different communication links can be used for communication between the first device 11 and the second device 12. 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 with each other through the second communication link 22. For another example, when the first communication link 21 cannot support the communication requirements, the first device 11 and the second device 12 can communicate with each other through the second communication link 22; or the first device 11 and the second device 12 can communicate with each other through 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. Thereby, the reliability of the vehicle electronic and electrical system 10 can be improved.

[0045] The situation where the first communication link 21 cannot support the transmission demand may be, for example but not limited to, that the transmission resources of the first communication link 21 are insufficient to meet the transmission demand between the first device 11 and the second device 12 .

[0046] Optionally, the communication type of the first communication link 21 is one of Ethernet communication, controller area network bus (ie, Controller Area Network, CAN), optical fiber communication, WiFi communication, and Bluetooth communication.

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

[0048] The specific embodiments of the present application are described below in conjunction with 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 are the same.

[0050] For example, the first communication link 21 is Ethernet communication and the second communication link 22 is Ethernet communication; or, the first communication link 21 is CAN communication and the second communication link 22 is 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, forming a path redundancy architecture of the ring network architecture. In addition, since the first communication link 21 and the second communication link 22 use the same communication type, it is more convenient to switch the communication link, simplify the stability of the electronic and electrical system 10, and facilitate control.

[0051] Optional, such as Figure 1 , the first device 11 and the second device 12 can be set to be independent of each other and back up each other. In the vehicle, the first device can include a cross-domain computing controller, and the second device can include a right-region controller. The cross-domain computing controller and the right-region controller adopt an inter-domain redundancy design. The cross-domain computing controller and the right-region controller can both include power control functions, steering & braking functions, body control functions, and chassis control functions. When any of the two domain controllers has a problem, the power control function, steering & braking function, body control function, and chassis control function can still operate normally.

[0052] Among them, Figure 2As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13, which is connected to the first communication link 21 and is located between the first device 11 and the second device 12, and can realize communication between the devices through the ring loop formed by the first communication link 21 and the second communication link 22. For example, when a communication failure occurs between the first communication link 21 and the third device 13, 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 through the second device 12 and the second communication link 22. For another example, when a communication failure occurs between the second device 12 and the third device 13 through 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 through the second communication link 22 via the first device 11.

[0053] It can be understood that redundant communication paths are provided between the two devices in the ring loop formed by the first communication link 21 and the second communication link 22. This ensures that when one communication path between the two devices fails, the communication between the two devices can be achieved through another 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 is located between the first device 11 and the second device 12. The communication between the devices can be realized through the ring loop formed by the first communication link 21 and the second communication link 22. For example, when the second communication link 22 has a communication failure between the first device 11 and the fourth device 14, the fourth device 14 can communicate with the second device 12 via the link between the second device 12 and the fourth device 14 through the second communication link 22; or, the fourth device 14 can also communicate with the first device 11 through the first communication link 21 via the second device 12. For another example, when the second communication link 22 has a communication failure between the second device 12 and the fourth device 14, the fourth device 14 can communicate with the first device 11 via the link between the first device 11 and the fourth device 14 through the second communication link 22; or, the fourth device 14 can also communicate with the second device 12 through the first communication link 21 via the first device 11.

[0055] It can be understood that the first communication link 21 and the second communication link 22 form a ring-shaped communication network, other devices can be connected to the first communication link 21 and the second communication link 22, and any two devices connected to the first communication link 21 or the second communication link have redundant communication paths. Equipping a vehicle with such a ring-shaped 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. In addition, the vehicle 100 also includes a front area controller, a rear area controller, an intelligent driving domain controller, and a cockpit domain controller, wherein the cross-domain computing controller, the right area controller, the front area controller, the rear area controller, the intelligent driving domain controller, and the cockpit domain controller can be connected through Ethernet, CAN bus, and LIN bus to achieve multi-terminal and multi-path interconnection. When one of the connection paths in the Ethernet, CAN bus, and LIN bus between any two domain controllers is disconnected, the connection can still be achieved through the undisconnected Ethernet, CAN bus, and LIN bus. Or the connection of the domain controller can be achieved and disconnected through indirect connection of other domain controllers, thereby realizing path redundancy and bus redundancy functions 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 is Ethernet communication, and the second communication link 22 is CAN communication; or the first communication link 21 is WiFi communication, and the second communication link 22 is optical fiber communication, etc. In such a scheme, the first communication link 21 and the second communication link 22 are redundant paths of different communication types, and can be configured as bus redundancy. When the first communication link 21 fails or the first communication link 21 cannot support the transmission demand, the second communication link 22 can be used to realize the communication between the first device 11 and the second device 12.

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

[0060] In addition, if Figure 5 As shown, in some possible implementations, the electronic and electrical system 10 may further include a third device 13, which 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 ring 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 further include a fourth device 14, which is connected to the second communication link 22 and is located between the first device 11 and the second device 12. Communication between the devices can be achieved through the ring 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 is communicatively connected to 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 through 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 achieve communication between the first device 11 and the second device 12 through the second communication link 22 and / or the third communication link 23. For another example, when the first communication link 21 cannot support the communication demand, 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, so as to better meet the transmission demand between the first device 11 and the second device 12. Thereby, the reliability of the vehicle electrical and electronic system 10 can be improved.

[0064] In the present application, a redundant communication link is provided between the first device 11 and the second device 12. Such a solution can avoid abnormal communication between the first device 11 and the second device 12 due to a failure of the communication link between the first device 11 and the second device 12 or the communication link cannot meet the communication requirements.

[0065] Among them, Figure 8As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13, which 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. The communication between the devices can be realized 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 communication link 21 and the third device 13, 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 and 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 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 Fig. 9 As 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 is located between the first device 11 and the second device 12. The 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 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 through the second communication link 22; 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 is one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and 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 from each other, or at least two of them can be the same.

[0068] like Fig.10As shown, in some possible implementations, the first communication link 21 and the second communication link 22 have the same communication type, and the third communication link 23 has a different communication type from the first communication link 21, and a path redundancy and bus redundancy architecture is constructed, 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 optical fiber 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. And the third communication link 23 forms a communication link of a different communication type outside the ring network. 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 the first communication link 21 cannot support the transmission demand, the second communication link 22 can be used to realize the 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 demand, the third communication link 23 can be used to realize the communication between the first device 11 and the second device 12.

[0069] like Fig.11 In some other possible implementations, the communication types of the first communication link 21 and the second communication link 22 are different, and the communication type of the third communication link 23 is the same as the communication type of the first communication link 21, for example, the first communication link 21 is Ethernet communication, the second communication link 22 is CAN communication, and the third communication link 23 is Ethernet communication; or the first communication link 21 is WiFi communication, the second communication link 22 is optical fiber communication, and the third communication link 23 is 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. It is constructed into a path redundancy and bus redundancy architecture.

[0070] like Fig.12 As shown, in some possible embodiments, the electronic and electrical system 10 also includes a third communication link 23 and a fourth communication link 24, 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, and the fourth communication link 24 communicatively connects the first device 11 and the second device 12, and the fourth communication link 24 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 with each other through the second communication link 22, the third communication link 23 and / or the fourth communication link 24. For another example, when the first communication link 21 cannot support the communication demand, the first device 11 and the second device 12 can communicate with each other 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 with each other 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, so as to better meet the transmission demand between the first device 11 and the second device 12. Thereby, the reliability of the vehicle electrical and electronic system 10 can be improved.

[0073] Among them, Fig.13 As shown, in some possible implementations, the electronic and electrical system 10 further includes a third device 13, which 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. The communication between the devices can be realized through the 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 communication link 21 and the third device 13, the third device 13 can communicate with the second device 12 via the link between the second device 12 and the third device 13 via 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 via 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 via the third communication link 23, etc.

[0074] like Fig.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 and is located between the first device 11 and the second device 12. The communication between the devices can be realized through the 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 through the second communication link 22; 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 through the fourth communication link 24; 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 through the fourth communication link 24, etc.

[0075] Optionally, the communication type of the third communication link 23 is one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and Bluetooth communication. Optionally, the communication type of the fourth communication link 24 is one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and Bluetooth communication. Among them, 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 in pairs, or at least two of them are the same. A Gigabit dual Ethernet ring network can be used between the first device and the second device, and a unique dual-ring topology structure design is used to achieve transmission path redundancy. Even if a connection is interrupted, the signal can still be transmitted stably, the breakpoint can be continued, and the link is more optimized.

[0076] like Fig.15As shown, in some possible implementations, the communication type of the first communication link 21 and the second communication link 22 is the same, the communication type of the third communication link 23 is different from the communication type of the first communication link 21, and the communication type of the fourth communication link 24 is the same as the communication type of 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 optical fiber communication, and the fourth communication link 24 is optical fiber 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 and the fourth communication link 24 can also form a ring loop, thereby forming a dual-ring network architecture. It is constructed into 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 requirement, the second communication link 22 can be used to realize the 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 requirement, the third communication link 23 and the fourth communication link 24 can be used to realize the communication between the first device 11 and the second device 12.

[0077] Among them, ring links of different communication types can be set up in parallel to form a double-layer ring network. Even if one of the buses fails to communicate due to an abnormality, communication can be carried out through another parallel bus, which improves the reliability of bus communication. For example, one of the ring networks (the ring network architecture composed of the first communication link and the second communication link) can be a Gigabit Ethernet bus; the other ring network (the ring network architecture composed of the third communication link and the fourth communication link) can be a CANFD bus.

[0078] like Fig.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 the communication type of the first communication link 21, and the communication type of the fourth communication link 24 is the same as the communication type 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 optical fiber communication, the third communication link 23 is WiFi communication, and the fourth communication link 24 is optical fiber 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 and the fourth communication link 24 can also form a ring loop, thereby forming a dual-ring network architecture. It is constructed into 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 includes at least one of a controller, a sensor, and an actuator. In combination with the aforementioned architecture of path redundancy and / or bus redundancy, stable communication between the first device 11 and the second device 12 can be maintained. When a communication link between the first device 11 and the second device 12 fails or cannot support transmission requirements, communication can still be performed through other communication links, and the stability of the electronic and electrical system 10 can be maintained.

[0080] Among them, 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 achieve stable communication between different devices.

[0081] In addition, the first device 11 and the second device 12 may also be configured as the same device, for example, the first device 11 is a controller and the second device 12 is a controller; or, the first device 11 is a sensor and the second device 12 is a sensor, etc. Furthermore, the first device 11 and the second device 12 may be configured to be independent of each other and back up each other to form a device redundancy architecture, and combined with the aforementioned path redundancy and / or bus redundancy architecture, a double redundancy or triple redundancy architecture is 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. When a communication link between the first device 11 and the second device 12 fails or cannot support transmission requirements, communication can still be performed through other communication links, thereby maintaining the stability of the electronic and electrical system 10.

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

[0084] The first device 11 and the second device 12 can be configured to be independent of each other and back up each other to form a device redundancy architecture, and combined with the aforementioned path redundancy and / or bus redundancy architecture to form a double redundancy or triple redundancy architecture.

[0085] The first device 11 and the second device 12 may adopt 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 may be different domain controllers. At least one of the first device 11 and the second device 12 may include a power control function, a steering & braking function, a body control function, and a chassis control function. When a problem occurs in any one of the two domain controllers, the power control function, the steering & braking function, the body control function, and the chassis control function can still operate normally.

[0086] For another example, the first device 11 is a cross-domain computing controller, the second device 12 is a right area controller, and a brake network link 25 may be connected between the first device 11 and the second device 12, and the brake network link 25 may be configured to be connected to signals such as a brake and a brake pedal; in addition, a power network link 26 may be connected between the first device 11 and the second device 12, and the power network link 26 may be configured to be connected to signals such as an accelerator and a powertrain.

[0087] In some possible embodiments, the first device 11 is configured to implement the first function, and the second device 12 is configured to implement the first function when the first device 11 is in the first state. When a single device is in the first state, the other can take over the control to ensure the reliable operation of safety-related functions such as parking brakes and collision unlocking, greatly improving safety and stability. Among them, the first device 11 and the second device 12 can be set to be independent of each other and back up each other to form a device redundancy architecture, combined with the aforementioned path redundancy and / or bus redundancy architecture, to form a double redundancy or triple redundancy architecture.

[0088] The first state includes a fault state, or a state where the first device 11 cannot meet the service demand alone, so that when a single device fails or cannot meet the demand, another device takes over or multiple devices operate together, so as to further improve the stability of the electronic and electrical system 10.

[0089] The first function may include at least one of a power control function, a steering function, a braking function, a body control function, and a chassis control function, so as to maintain the control function, 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 may be the first domain controller of the vehicle, and the second device 12 may be the cross-domain computing controller of the vehicle to maintain the stable operation of the vehicle. The first domain controller may be a smart driving domain controller, a cockpit domain controller, a right area controller, a front area controller, and a rear area controller, etc., and stable communication between the cross-domain computing controller and the smart 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 may be achieved through the aforementioned path redundant links and / or bus redundant wiring harnesses.

[0091] In some possible embodiments, the electronic and electrical system 10 further includes a third device 13, which is connected to the first communication link 21 and is 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. In addition, the third device 13 may also be a front zone controller of the vehicle.

[0092] In addition, in some embodiments, the electronic and electrical system 10 further includes a fourth device 14, which is connected to the second communication link 22 and is 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. In addition, the fourth device 14 may be a rear area controller of the vehicle.

[0093] like Fig.17In some possible embodiments, the first device 11 may be a cross-domain computing controller, the second device 12 may be a right region controller, the third device 13 may be a rear region controller, and the fourth device 14 may be a front region controller. The first communication link 21 connects the cross-domain computing controller, the rear region controller, and the right region controller; the second communication link connects the cross-domain computing controller, the front region controller, and the right region controller; the third communication link connects the cross-domain computing controller, the rear region controller, and the right region controller; the fourth communication link connects the cross-domain computing controller, the front region controller, and the right region controller. Among them, the first communication link may be the same as the communication type of the second communication link, the third communication link may be the same as the communication type of the fourth communication link, and the first communication link may be different from the communication type of the third communication link.

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

[0095] Fig.17 This is a schematic diagram of the path redundancy & bus redundancy structure of a triple redundant architecture based on a domain controller of the present invention. The present invention adopts a dual-ring network communication link and realizes transmission path redundancy with a unique dual-ring topology structure design. Even if the connection in one domain is interrupted, the communication connection between domain controllers can still be realized through other paths, maintaining stable signal transmission, and the breakpoint can be continued, and the link is more optimized.

[0096] Among them, the cross-domain computing controller and the front-region controller can communicate via Ethernet. When an abnormality occurs in the Ethernet path and direct communication via Ethernet is impossible, the Ethernet connection between the cross-domain computing controller and the rear-region controller can still be used, and then the communication between the cross-domain computing controller and the front-region controller can be achieved through the rear-level Ethernet bridging.

[0097] In addition, a Gigabit Ethernet bus can be used between the cross-domain computing controller and the front area controller, and set up in parallel with the CAN bus, CAN bus with Flexible Data rate (CANFD) or Local Interconnect Network (LIN) to form a double-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 by multiple buses through Ethernet, CAN bus, CANFD bus and LIN bus. When one of the Ethernet / CAN bus / LIN bus connections between any two domain controllers is disconnected, the connection can still be achieved through the parallel Ethernet / CAN bus / CANFD bus / LIN bus that is not disconnected.

[0098] In addition, the first device 11 may include at least one of a power controller 101, a steering & braking controller 102, a body controller 103 and a chassis controller 104, and 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 on an equal footing, and the first device and the second device backup 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] The present invention proposes a multiple redundant architecture based on a domain controller, a redundant architecture with at least two communication links between a first device and a second device, which can simultaneously deploy the key subsystems of the vehicle on two independent domain controllers to back up each other. The triple redundant architecture based on the domain controller sets up the vehicle-mounted Gigabit Ethernet bus and the CANFD bus in parallel to form a double-layer ring network.

[0100] In some specific examples of the present invention, Fig.18 This is a schematic diagram of the domain redundancy structure of a triple redundant architecture based on a domain controller of the present invention. It adopts AMP architecture (asymmetric multi-processing) core deployment, runs a system on both the first device and the second device, and ensures functional safety in a dual-core lock-step operation manner. By learning from the bionics of the octopus heart, the safety-critical subsystem is innovatively deployed on two independent domain controllers at the same time to back up each other.

[0101] Fig.18The middle cross-domain computing controller and the right regional controller adopt an inter-domain redundancy design. Both the cross-domain computing controller and the right regional controller include power control functions, steering & braking functions, body control functions, and chassis control functions. When any of the two domain controllers has a problem, the power control function, steering & braking function, body control function, and chassis control function can still operate normally. When a single controller fails, the other can take over control to ensure the reliable operation of safety-related functions such as parking brakes and collision unlocking, greatly improving safety and stability.

[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 the safety-critical subsystem on two independent domain controllers, which back up each other, and form a three-layer redundancy in combination with the above-mentioned dual ring network architecture. When a single controller fails, the other can take over the control. When a communication link fails, communication can be carried out through a redundant communication link to ensure that safety-related functions such as parking brakes and collision unlocking can still operate reliably, greatly improving the safety and stability of the system.
