DETAILED DESCRIPTION
[0042] The technical solutions in some embodiments of the present disclosure will be described below with reference to the accompanying drawings.
[0043] Because vehicles incorporate a large number of high-end electronic and electrical components, communication between these components is critical, and the realization of various vehicle functions relies on the vehicle's electronic and electrical systems. If a failure occurs in the vehicle's electronic and electrical architecture, it may affect the entire vehicle's operation.
[0044] FIG1 is a schematic diagram of the architecture of an electronic and electrical system 10 according to some embodiments of the present disclosure. As shown in FIG1 , 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, while 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 via the first communication link 21; or the first device 11 and the second device 12 can communicate via the second communication link 22; or the first device 11 and the second device 12 can communicate via the first communication link 21 and the second communication link 22.
[0045] When the electronic and electrical system 10 is in different operating states, the first device 11 and the second device 12 may communicate with each other using different communication links.
[0046] 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 implement communication between the first device 11 and the second device 12 through the second communication link 22 .
[0047] For another example, when the first communication link 21 cannot support communication requirements, the first device 11 and the second device 12 can communicate via the second communication link 22; or the first device 11 and the second device 12 can communicate via the first communication link 21 and the second communication link 22, thereby better meeting the transmission requirements between the first device 11 and the second device 12. This can improve the reliability of the vehicle electronic and electrical system 10.
[0048] For example, the situation where the first communication link 21 cannot support the transmission requirement may include but is not limited to: the transmission resources of the first communication link 21 are insufficient to meet the transmission requirement between the first device 11 and the second device 12 .
[0049] In some embodiments, the communication type of the first communication link 21 may be one of Ethernet communication, Controller Area Network (CAN) communication, optical fiber communication, WiFi communication, and Bluetooth communication.
[0050] In some embodiments, the communication mode of the second communication link 22 can be one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and Bluetooth communication.
[0051] Some embodiments of the present disclosure are described below with reference to the accompanying drawings.
[0052] In some embodiments, as shown in FIG1 , the first communication link 21 and the second communication link 22 are of the same communication type.
[0053] 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 solution, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type.
[0054] It is understood that in such a solution, 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. Furthermore, because the first communication link 21 and the second communication link 22 use the same communication type, communication link switching can be more convenient, improving the stability of the electronic and electrical system 10 and facilitating control.
[0055] In some embodiments, as shown in 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 11 may include a cross-domain computing controller, and the second device 12 may include a right area controller. The cross-domain computing controller and the right area controller adopt an inter-domain redundancy design, and the cross-domain computing controller and the right area controller can both include power control functions, steering and braking functions, body control functions, and chassis control functions. When a problem occurs in any of the two domain controllers (such as the cross-domain computing controller and the right area controller), the power control function, steering and braking functions, body control functions, and chassis control functions can still operate normally.
[0056] In some examples, as shown in FIG2 , 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. In this way, communication between the devices can be achieved through the loop formed by the first communication link 21 and the second communication link 22.
[0057] For example, when a communication failure occurs in the first communication link 21 between the first device 11 and the third device 13, the third device 13 can communicate with the second device 12 via the first communication link 21 between the second device 12 and the third device 13; or, the third device 13 can also communicate with the first device 11 via the second device 12 through the second communication link 22.
[0058] For another example, when a communication failure occurs in the first communication link 21 between the second device 12 and the third device 13, the third device 13 can communicate with the first device 11 via the first communication link 21 between the first device 11 and the third device 13; or, the third device 13 can also communicate with the second device 12 via the first device 11 through the second communication link 22.
[0059] It is understandable 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, communication between the two devices can be achieved through the other communication path.
[0060] In other examples, as shown in FIG3 , the electronic and electrical system further includes a fourth device 14. The fourth device 14 is connected to the second communication link 22 and is located between the first device 11 and the second device 12. In this way, communication between the various devices can be achieved through the loop formed by the first communication link 21 and the second communication link 22.
[0061] For example, when a communication failure occurs in the second communication link 22 between the first device 11 and the fourth device 14, the fourth device 14 can communicate with the second device 12 via the second communication link 22 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.
[0062] For another example, when a communication failure occurs in the second communication link 22 between the second device 12 and the fourth device 14, the fourth device 14 can communicate with the first device 11 via the second communication link 22 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 through the first communication link 21.
[0063] It is 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. A redundant communication path exists between any two devices connected to the first communication link 21 or the second communication link. Equipping a vehicle with such a ring-shaped communication network can improve the reliability of communication between various components in the vehicle's electrical and electronic systems.
[0064] 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. 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 interconnected by Ethernet, CAN bus, and local area interconnect network (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.
[0065] In other embodiments, as shown in FIG. 4 , the communication types of the first communication link 21 and the second communication link 22 are different.
[0066] For example, the first communication link 21 may be Ethernet communication, and the second communication link 22 may be CAN communication; or the first communication link 21 may be WiFi communication, and the second communication link 22 may be fiber optic communication. In such a solution, 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. If the first communication link 21 fails or cannot support transmission requirements, the second communication link 22 can be used to enable communication between the first device 11 and the second device 12.
[0067] It can be understood that in such a solution, 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.
[0068] In addition, in some examples, as shown in FIG5 , the electronic and electrical system 10 may further include 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. In this way, communication between the various devices can be achieved through the loop formed by the first communication link 21 and the second communication link 22.
[0069] In other examples, as shown in FIG6 , the electronic and electrical system may further include a fourth device 14. The fourth device 14 is connected to the second communication link 22 and is located between the first device 11 and the second device 12. In this way, communication between the various devices can be achieved through the loop formed by the first communication link 21 and the second communication link 22.
[0070] 7 , the electronic and electrical system 10 further includes a third communication link 23 . The third communication link 23 communicatively connects the first device 11 and the second device 12 . The third communication link 23 is used for communication between the first device 11 and the second device 12 .
[0071] For example, 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 .
[0072] It should be noted that “at least one of A, B and C” has the same meaning as “at least one of A, B or C”, both including the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.
[0073] 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 at least one of the second communication link 22 or the third communication link 23.
[0074] For another example, when the first communication link 21 cannot support communication requirements, the first device 11 and the second device 12 can communicate via the second communication link 22; or the first device 11 and the second device 12 can communicate via the third communication link 23; or the first device 11 and the second device 12 can also communicate via 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 electronic and electrical system 10.
[0075] In some embodiments of the present disclosure, a redundant communication link is provided between the first device 11 and the second device 12. This 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 inability of the communication link to meet communication requirements.
[0076] In some examples, as shown in FIG8 , 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. In this way, communication between the various 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.
[0077] For example, when a communication failure occurs in the first communication link 21 between the first device 11 and the third device 13, the third device 13 can communicate with the second device 12 via the first communication link 21 between the second device 12 and the third device 13; 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 third communication link 23 between the second device 12 and the third device 13; or, the third device 13 can also communicate with the first device 11 via the third communication link 23 between the first device 11 and the third device 13, etc.
[0078] In other examples, as shown in FIG9 , the electronic and electrical system 10 further includes a fourth device 14. The fourth device 14 is connected to the second communication link 22 and is located between the first device 11 and the second device 12. In this way, communication between the various 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.
[0079] For example, when a communication failure occurs in the second communication link 22 between the first device 11 and the fourth device 14, the fourth device 14 can communicate with the second device 12 via the second communication link 22 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 at least one of the first communication link 21 or the third communication link 23.
[0080] In some embodiments, 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.
[0081] In some examples, as shown in FIG10 , 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 from the first communication link 21, thereby creating a path redundancy and bus redundancy architecture. For example, the first communication link 21 may be Ethernet communication, the second communication link 22 may be Ethernet communication, and the third communication link 23 may be CAN communication; or the first communication link 21 may be WiFi communication, the second communication link 22 may be WiFi communication, and the third communication link 23 may be fiber optic communication.
[0082] It will be appreciated that in such a solution, the first communication link 21 and the second communication link 22 can form a ring-shaped loop. The third communication link 23 forms a communication link of a different communication type outside the ring network. Furthermore, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type. If the first communication link 21 fails or cannot support transmission requirements, the second communication link 22 can be used to enable communication between the first device 11 and the second device 12. Furthermore, if the ring network communication link formed by the first communication link 21 and the second communication link 22 fails or cannot support transmission requirements, the third communication link 23 can be used to enable communication between the first device 11 and the second device 12.
[0083] In other examples, as shown in FIG11 , 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 fiber optic communication, and the third communication link 23 is WiFi communication, etc.
[0084] It is understood that in such a solution, the first communication link 21 and the third communication link 23 can form a ring loop, while the second communication link 22 forms a communication link of a different communication type outside the ring network, thereby forming a path redundancy and bus redundancy architecture.
[0085] In some embodiments, as shown in FIG12 , the electronic and electrical system 10 further includes a third communication link 23 and a fourth communication link 24. The third communication link 23 communicatively connects the first device 11 and the second device 12, and is used for communication between the first device 11 and the second device 12. The fourth communication link 24 communicatively connects the first device 11 and the second device 12, and is used for communication between the first device 11 and the second device 12.
[0086] 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 , the third communication link 23 and the fourth communication link 24 .
[0087] 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 at least one of the second communication link 22, the third communication link 23 or the fourth communication link 24.
[0088] For another example, when the first communication link 21 cannot support communication requirements, the first device 11 and the second device 12 can communicate via the second communication link 22, the third communication link 23, or the fourth communication link 24. Alternatively, the first device 11 and the second device 12 can communicate via 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 electronic and electrical system 10.
[0089] In some examples, as shown in FIG13 , 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. In this way, communication between the various devices can be achieved 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.
[0090] For example, when a communication failure occurs in the first communication link 21 between the first device 11 and the third device 13, the third device 13 can communicate with the second device 12 via the first communication link 21 between the second device 12 and the third device 13; or, the third device 13 can also communicate with the first device 11 via the second device 12, through at least one of the second communication link 22 or the fourth communication link 24; or the third device 13 can also communicate with the second device 12 via the third communication link 23 between the second device 12 and the third device 13; or, the third device 13 can also communicate with the first device 11 via the third communication link 23 between the first device 11 and the third device 13, etc.
[0091] In other examples, as shown in FIG14 , the electronic and electrical system 10 further includes a fourth device 14. The fourth device 14 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. Redundant design of the first communication link 21, the second communication link 22, the third communication link 23, and the fourth communication link 24 can be used to implement communication between the various devices.
[0092] For example, when a communication failure occurs in the second communication link 22 between the first device 11 and the fourth device 14, the fourth device 14 can communicate with the second device 12 via the second communication link 22 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 at least one of the first communication link 21 or the third communication link 23; or, the fourth device 14 can also communicate with the second device 12 via the fourth communication link 24 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 fourth communication link 24 between the first device 11 and the fourth device 14, etc.
[0093] In some embodiments, the communication type of the third communication link 23 may be one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and Bluetooth communication. The communication type of the fourth communication link 24 may be one of Ethernet communication, CAN communication, optical fiber communication, WiFi communication, and Bluetooth communication.
[0094] Here, 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 two of them can be the same. A Gigabit dual Ethernet ring network can be used between the first and second devices, achieving transmission path redundancy through a unique dual-ring topology design. Even if a connection is interrupted, signal transmission can still be maintained stably, and transmission can be resumed at the breakpoint, further optimizing the link.
[0095] In some embodiments, as shown in Figure 15, 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.
[0096] 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.
[0097] It will be appreciated that in such a solution, 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. This creates a path redundancy and bus redundancy architecture. Furthermore, the first communication link 21 and the second communication link 22 are redundant paths of the same communication type. If the first communication link 21 fails or cannot support transmission requirements, the second communication link 22 can be used to enable communication between the first device 11 and the second device 12. Furthermore, if the ring network communication link formed by the first communication link 21 and the second communication link 22 fails or cannot support transmission requirements, the third communication link 23 and the fourth communication link 24 can be used to enable communication between the first device 11 and the second device 12.
[0098] In some embodiments, 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 still be carried out through the other parallel bus, thereby improving the reliability of bus communication. For example, one of the ring networks (such as the ring network architecture composed of the first communication link 21 and the second communication link 22) can be a Gigabit Ethernet bus; the other ring network (such as the ring network architecture composed of the third communication link 23 and the fourth communication link 24) can be a CAN bus with Flexible Data rate (CANFD).
[0099] In other embodiments, as shown in Figure 16, 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.
[0100] 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.
[0101] It is understood that in such a solution, 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, which is constructed to achieve path redundancy and bus redundancy.
[0102] In some embodiments, the electronic and electrical system 10 satisfies at least one of the following conditions: the first device 11 may include at least one of a controller, a sensor, and an actuator; or the second device 12 may include at least one of a controller, a sensor, and an actuator. Combined with the aforementioned architecture of at least one of path redundancy or bus redundancy, stable communication between the first device 11 and the second device 12 can be maintained. Even if a communication link between the first device 11 and the second device 12 fails or cannot support transmission requirements, communication can still be carried out through other communication links, thereby maintaining the stability of the electronic and electrical system 10.
[0103] In some examples, the first device 11 and the second device 12 may be different devices. For example, the first device 11 may be a controller and the second device 12 may be a sensor; or the first device 11 may be a controller and the second device 12 may be an actuator. In this way, stable communication between different devices can be achieved.
[0104] Of course, in other examples, 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.
[0105] Furthermore, 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 at least one of the aforementioned path redundancy or bus redundancy architecture to form a double redundancy or triple redundancy architecture.
[0106] In some embodiments, at least one of the first device 11 or the second device 12 is a domain controller. Combined with the aforementioned architecture of at least one of path redundancy or bus redundancy, 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 carried out through other communication links, thereby maintaining the stability of the electronic and electrical system 10.
[0107] 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 redundant. If the first device 11 fails or cannot support service requirements, the second device 12 can implement the first function.
[0108] 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 at least one of the aforementioned path redundancy or bus redundancy architectures, a double redundancy or triple redundancy architecture is formed.
[0109] 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.
[0110] For example, the first device 11 and the second device 12 may be different domain controllers. At least one of the first device 11 or the second device 12 may include power control functions, steering and braking functions, body control functions, and chassis control functions. If a problem occurs in either of the two domain controllers, the power control functions, steering and braking functions, body control functions, and chassis control functions may still operate normally.
[0111] For another example, the first device 11 is a cross-domain computing controller, and the second device 12 is a right-domain controller. A brake network link can be connected between the first device 11 and the second device 12. This brake network link can be configured to connect to signals such as the brake and brake pedal. In addition, a power network link can be connected between the first device 11 and the second device 12. This power network link can be configured to connect to signals such as the throttle and powertrain.
[0112] In some embodiments, the first device 11 is configured to implement a first function, and the second device 12 is configured to implement the first function when the first device 11 is in a first state. When a single device is in the first state, the other device can take over control, ensuring the reliable operation of related functions such as parking brakes and collision unlocking, greatly improving reliability and stability. The first device 11 and the second device 12 can be configured to be independent and mutually backed up, forming a device redundancy architecture. Combined with at least one of the aforementioned path redundancy or bus redundancy architectures, this can form a dual-redundancy or triple-redundancy architecture.
[0113] The first state includes a fault state, or a state where the first device 11 cannot meet business requirements alone, so that when a single device fails or cannot meet the requirements, another device takes over or multiple devices operate together to further improve the stability of the electronic and electrical system 10.
[0114] The first function may include at least one of a power control function, a steering function, a braking function, a body control function, or a chassis control function, so as to maintain the control function, steering function, braking function, body control function, chassis control function, etc. of the electronic and electrical system 10.
[0115] In some embodiments, the first device 11 may be a first domain controller of the vehicle, and the second device 12 may be a cross-domain computing controller of the vehicle to maintain stable operation of the vehicle. The first domain controller may be a smart driving domain controller, a cockpit domain controller, a right region controller, a front region controller, and a rear region controller, etc. 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 region controller, between the cross-domain computing controller and the front region controller, or between the cross-domain computing controller and the rear region controller may be achieved through at least one of the aforementioned path redundant links or bus redundant wiring harnesses.
[0116] In some embodiments, 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.
[0117] In some embodiments, 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.
[0118] In some embodiments, as shown in FIG17 , 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. A first communication link 21 connects the cross-domain computing controller, the rear region controller, and the right region controller; a second communication link 22 connects the cross-domain computing controller, the front region controller, and the right region controller; a third communication link 23 connects the cross-domain computing controller, the rear region controller, and the right region controller; and a fourth communication link 24 connects the cross-domain computing controller, the front region controller, and the right region controller.
[0119] The first communication link 21 may be of the same communication type as the second communication link 22 , the third communication link 23 may be of the same communication type as the fourth communication link 24 , and the first communication link 21 may be of a different communication type than the third communication link 23 .
[0120] In addition, the electronic and electrical system 10 may further include a fifth device 15 and a sixth device 16. The first device 11, the fifth device 15, and the sixth device 16 may be connected via a communication link to form a ring network redundant architecture. For example, the fifth device 15 may be an intelligent driving domain controller, and the sixth device 16 may be a cockpit domain controller. The cross-domain computing controller, the intelligent driving domain controller, and the cockpit domain controller may be connected via a communication link to form a ring network architecture.
[0121] Figure 17 is a schematic diagram of path and bus redundancy in a triple-redundant architecture based on a domain controller according to the present disclosure. Some embodiments of the present disclosure utilize dual-ring network communication links, achieving transmission path redundancy through a unique dual-ring topology design. Even if one connection is interrupted, communication between domain controllers can still be established through other paths, maintaining stable signal transmission, enabling resumable transmission at breakpoints, and optimizing links.
[0122] The cross-domain computing controller and the front-region controller can communicate via Ethernet. When an Ethernet path anomaly occurs and direct communication via Ethernet is impossible, communication between the cross-domain computing controller and the rear-region controller can still be achieved through the Ethernet connection between the cross-domain computing controller and the rear-region controller, and then through the subsequent Ethernet bridging to achieve communication between the cross-domain computing controller and the front-region controller.
[0123] In addition, a Gigabit Ethernet bus can be used between the cross-domain computing controller and the front zone controller, running in parallel with the CAN bus, CANFD bus, or LIN bus to form a double-layer ring network and achieve bus redundancy. The cross-domain computing controller, right zone controller, front zone controller, rear zone controller, intelligent driving domain controller, and cockpit domain controller are interconnected via Ethernet, CAN bus, CANFD bus, and LIN bus. If one of the Ethernet, CAN bus, CANFD bus, or LIN bus connections between any two domain controllers is disconnected, they can still be connected via the parallel Ethernet, CAN bus, CANFD bus, or LIN bus.
[0124] Furthermore, as shown in FIG18 , the first device 11 may include at least one of a powertrain controller 101, a steering and braking controller 102, a body controller 103, or a chassis controller 104. The second device 12 may be identical to the first device 11, and the first and second devices 11, 12 are independent of each other. In other words, the first and second devices 11, 12 can communicate equally with other components, and the first and second devices 11, 12 serve as backups for each other. If the first device 11 fails, the second device 12 can replace the first device 11; if the second device 12 fails, the first device 11 can replace the second device 12.
[0125] Some embodiments of the present disclosure propose a domain controller-based multi-redundancy architecture with at least two communication links between a first device 11 and a second device 12. This architecture allows the simultaneous deployment of critical vehicle subsystems on two independent domain controllers, providing mutual backup. This domain controller-based triple-redundancy architecture parallelizes the vehicle's Gigabit Ethernet bus and the CANFD bus, forming a dual-layer ring network.
[0126] In some embodiments of the present disclosure, FIG18 is a schematic diagram of the inter-domain redundancy structure of a triple-redundant architecture based on a domain controller. As shown in FIG18 , an asymmetric multi-processing (AMP) architecture is employed for core deployment, with a single system running on both first device 11 and second device 12, ensuring functional reliability through dual-core lockstep operation. By incorporating bionic elements from the octopus heart, this innovative approach allows the simultaneous deployment of critical vehicle subsystems on two independent domain controllers, providing mutual backup.
[0127] In Figure 18, the cross-domain computing controller (e.g., first device 11) and the right-domain controller (e.g., second device 12) employ an inter-domain redundant design. Both the cross-domain computing controller and the right-domain controller include powertrain control, steering and braking, body control, and chassis control functions. If a problem occurs in either domain controller, the powertrain, steering and braking, body control, and chassis control functions will continue to operate normally. If a single controller fails, the other controller can take over control, ensuring the reliable operation of related functions such as parking brake and collision release, greatly improving reliability and stability.
[0128] The communication type of each communication link in some embodiments of the present disclosure is not limited to the examples in the above embodiments. The type and function of each device in some embodiments of the present disclosure are not limited to the examples in the above embodiments.
[0129] Some embodiments of the present disclosure also provide a vehicle 100 (as shown in FIG18 ), including the aforementioned electronic and electrical system 10. The vehicle 100 of some embodiments of the present disclosure can simultaneously deploy key subsystems on two independent domain controllers, which serve as backups for each other. Combined with the above-mentioned dual ring network architecture, a three-layer redundancy is formed. When a single controller fails, the other can take over control. When a communication link fails, communication can be carried out through a redundant communication link to ensure that related functions such as parking brake and collision unlocking can still operate reliably, greatly improving the reliability and stability of the system.
