[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] In a first aspect, an embodiment of the present application provides a vehicle status detection method.

[0038] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of a vehicle status detection method of the present application. Figure 1 As shown, the vehicle state detection method includes:

[0039] Step S10: deploy Ethernet OAM for multiple components of the vehicle that require status detection.

[0040] In this embodiment, the multiple components of the vehicle refer to the software and hardware with independent functions in the entire vehicle system, including but not limited to the engine, transmission, suspension, braking system and air-conditioning system. In order to ensure the safety and reliability of the vehicle, it is necessary to timely detect the functional status of each component of the vehicle and the communication status between each component. OAM (Operation Administration and Maintenance), Ethernet OAM is the operation management and maintenance for Ethernet. Ethernet OAM is a tool for monitoring network faults. Its main functions include: link performance monitoring: monitoring various performance of the link, including measurement of packet loss, delay and jitter, as well as statistics of various types of traffic; fault detection and alarm: detecting the connectivity of the link by sending detection messages, and notifying the network administrator in time when a link fails; loop test: detecting link failures by looping back non-Ethernet OAM protocol messages. In this embodiment, Ethernet OAM is deployed for multiple components of the vehicle that need to perform status detection. The chips of the corresponding vehicle components need to support the relevant protocols for deploying Ethernet OAM. The protocols mainly include the Y.1731 protocol of the ITU-T organization and the 802.1ag protocol of the IEEE organization. If multiple components of the vehicle need to support Ethernet OAM and CAN communication at the same time, the chips of the corresponding vehicle components need to support the Y.1731 protocol, the 802.1ag protocol and the CAN communication protocol at the same time. Among them, 802.1ag is a standard proposed by IEEE for error management in Carrier Ethernet networks, also known as Connectivity Fault Management (CFM), which provides five functions such as path discovery, fault detection, fault confirmation and location, fault notification and fault recovery. Y.1731 is an OAM protocol proposed by the ITU-T standards organization. It not only includes the content specified by IEEE 802.1ag, but also adds more OAM message combinations, including AIS (Alarm Indication Signal), RDI (Remote Defect Indication), LCK (Locked Signal), test signal, APS (Automatic Protection Switching), MCC (Maintenance Communication Channel), EXP (Experimental OAM), vendor-specific VSP (Vendor Specific OAM) fault management, and packet loss management and delay evaluation for performance monitoring.

[0041] Step S20, obtaining status information of multiple components of the vehicle and communication status between the multiple components through Ethernet OAM.

[0042] In this embodiment, the status information of multiple components of the vehicle and the communication status between multiple components are obtained based on Ethernet OAM, for example, the status information of the component is obtained through the status flag bit carried in the message sent by each component, and the link status between multiple components is determined through the continuity detection function and loopback function of Ethernet OAM. Compared with vehicles using CAN communication, vehicles using Ethernet OAM can flexibly adopt various Ethernet network architectures to establish communication connections between various components of the vehicle. Through the mechanism of Ethernet OAM, the status information of multiple components of the vehicle and the communication status between multiple components can be quickly obtained. Compared with vehicles using CAN communication, it has higher status and fault detection efficiency, which is of great significance for improving the safety and reliability of the vehicle.

[0043] In this embodiment, Ethernet OAM is deployed for multiple components of the vehicle that need to be state-detected. The chip of the corresponding vehicle component needs to support the relevant protocols for deploying Ethernet OAM. The protocols mainly include the Y.1731 protocol of the ITU-T organization and the 802.1ag protocol of the IEEE organization. If multiple components of the vehicle need to support Ethernet OAM and CAN communication at the same time, the chip of the corresponding vehicle component needs to support the Y.1731 protocol, the 802.1ag protocol and the CAN communication protocol at the same time. For example, the status information of the component is obtained through the status flag bit carried in the message sent by each component, and the link status between multiple components is determined by the continuity detection function and loopback function of Ethernet OAM. Compared with vehicles using CAN communication, vehicles using Ethernet OAM can flexibly adopt various Ethernet network architectures to establish communication connections between various components of the vehicle. Through the mechanism of Ethernet OAM, the status information of multiple components of the vehicle and the communication status between multiple components can be quickly obtained. Compared with vehicles using CAN communication, it has higher status and fault detection efficiency, which is of great significance for improving the safety and reliability of the vehicle.

[0044] Further, in one embodiment, referring to Figure 2 , Figure 2 For this application Figure 1 The detailed flow chart of step S10 is as follows: Figure 2 As shown, step S10 includes:

[0045] Step S101, deploying Ethernet OAM communication protocols for multiple components of a vehicle that need to be checked for status;

[0046] Step S102, creating a maintenance domain for multiple components of the vehicle that need to be checked for status;

[0047] Step S103, configuring a maintenance set for the maintenance domain;

[0048] Step S104, configuring maintenance endpoints for the maintenance set, wherein each vehicle component corresponds to a maintenance endpoint.

[0049] In this embodiment, Ethernet OAM communication protocols are deployed for multiple components of the vehicle that need to be state-detected, and the protocols mainly include the Y.1731 protocol of the ITU-T organization and the 802.1ag protocol of the IEEE organization. In this embodiment, the Ethernet OAM mechanism can be implemented based on CFD (Connectivity Fault Detection). CFD follows the CFM (Connectivity Fault Management) protocol of IEEE802.1ag and the Y.1731 protocol of ITU-T. It is an end-to-end OAM mechanism for a layer 2 network, which is mainly used to detect link connectivity in a layer 2 network, and to confirm and locate faults when faults occur. Applicable layer 2 networks include Ethernet networks based on VLAN (Virtual Local Area Network) and layer 2 VPN (Virtual Private Network) networks based on MPLS (Multi-Protocol Label Switching). Specifically, a maintenance domain MD (Maintenance Domain) is created for multiple components of the vehicle that need to be checked for status. The maintenance domain MD refers to a network or a part of a network covered by connectivity error detection, and is identified by the "MD name". Then, a maintenance association MA (Maintenance Association) is configured for the maintenance domain MD. The maintenance association MA is a part of the maintenance domain MD. A maintenance domain MD can be divided into one or more maintenance association MAs, which are identified by "MD name + MA name". In an Ethernet network, a maintenance association MA can serve a specified VLAN or not serve any VLAN, which are respectively called maintenance association MAs with VLAN attributes and maintenance association MAs without VLAN attributes. In a Layer 2 VPN network, a maintenance association MA can only serve a specified cross-connection or virtual switching instance.Then configure the maintenance association End Point (MEP) for the MA. The MEP belongs to the maintenance point (MP). The maintenance point MP is configured on the interface and belongs to a maintenance association MA. The maintenance point MP also includes the maintenance intermediate point (MIP). The MEP determines the boundary of the MA. The maintenance endpoint MEP is identified by the "ID". In the Ethernet network, the maintenance set MA to which the maintenance endpoint MEP belongs determines the VLAN to which the message sent by the maintenance endpoint MEP belongs. In the Layer 2 VPN network, the maintenance set MA to which the maintenance endpoint MEP belongs determines the cross-connection or virtual switching instance to which the message sent by the maintenance endpoint MEP belongs. The maintenance endpoint MEP has directionality and is divided into two types: inward MEP and outward MEP: the inward MEP will not send CFD protocol messages through the interface where it is located. In the Ethernet network, the inward MEP broadcasts CFD protocol messages through all other interfaces in the VLAN served by the MA to which it belongs. In the Layer 2 VPN network, the inward MEP broadcasts CFD protocol messages through all other interfaces in the cross-connection or virtual switching instance to which it belongs, and the outward MEP directly sends CFD protocol messages outward through the interface where it is located. The maintenance intermediate point MIP is located inside the maintenance set MA and cannot actively send CFD protocol messages, but can process and respond to CFD protocol messages. The maintenance intermediate point MIP is automatically created by the device and can cooperate with MEP to complete functions similar to ping (Packet Internet Groper) and tracert (route tracking). The maintenance set MA to which the maintenance intermediate point MIP belongs determines the VLAN to which the message that the maintenance intermediate point MIP can receive belongs. The maintenance intermediate point MIP configuration is only effective in the Ethernet network and not in the Layer 2 VPN network. The maintenance endpoint MEP list is a collection of local MEPs that are allowed to be configured and remote MEPs that need to be monitored in the same maintenance set MA. It limits the selection range of the maintenance endpoint MEP in the maintenance set MA. All maintenance endpoint MEPs in the same maintenance set MA on different devices should be included in this list, and the MEP IDs are not repeated. If the maintenance endpoint MEP receives a CCM (Continuity Check Message) message from a remote device and the MEP carried by the message is not in the MEP list of the same MA, the message is discarded. Among them, when configuring the communication of each maintenance endpoint MEP, the physical address of the device is configured to represent the corresponding vehicle component, so that each vehicle component corresponds to a maintenance endpoint.

[0050] Furthermore, in one embodiment, step S20 includes:

[0051] The connectivity status between the maintenance endpoints is detected by sending continuity detection messages between the maintenance endpoints to determine the communication status between the vehicle components corresponding to the maintenance endpoints.

[0052] In this embodiment, the connectivity failure between the maintenance endpoint MEPs may be caused by equipment failure or configuration error. The continuity check (CC) function is used to detect the connectivity status between the maintenance endpoint MEPs. The implementation of this function is as follows: the maintenance endpoint MEP periodically sends CCM messages, and other maintenance endpoint MEPs in the same maintenance set MA receive the messages and thereby learn the remote status. If the maintenance endpoint MEP does not receive the CCM message sent by the remote MEP within 3.5 CCM message sending cycles, it is considered that there is a problem with the link and a log report will be output. When multiple maintenance endpoint MEPs in the maintenance domain MD send CCM messages, multi-point to multi-point link detection is implemented, where the CCM message is a multicast message. Since each vehicle component corresponds to a maintenance endpoint, the connectivity status between the maintenance endpoints is detected by sending continuity check messages between the maintenance endpoints, so that the communication status between the vehicle components corresponding to the maintenance endpoints can be determined.

[0053] Furthermore, in one embodiment, step S20 further includes:

[0054] The source maintenance endpoint sends a loopback message to the target maintenance endpoint to detect the link status between the source maintenance endpoint and the target maintenance endpoint, so as to determine the communication status between the vehicle components respectively corresponding to the source maintenance endpoint and the target maintenance endpoint.

[0055] In this embodiment, the loopback (LB) function of Ethernet OAM is similar to the ping function of the IP (Internet Protocol) layer, which is used to verify the connection status between the source maintenance endpoint MEP and the target maintenance endpoint MP. The implementation method of this function is: the source maintenance endpoint MEP sends an LBM (Loopback Message) message to the target maintenance endpoint MP, and checks the link status based on whether the LBR (Loopback Reply) message fed back by the other end can be received. The LBM message is divided into two types of messages: multicast and unicast. The device supports sending and processing unicast LBM messages, but does not support sending but can process multicast LBM messages. LBR is a unicast message. Therefore, the source maintenance endpoint sends a loopback message to the target maintenance endpoint to detect the link status between the source maintenance endpoint and the target maintenance endpoint, so as to determine the communication status between the vehicle components corresponding to the source maintenance endpoint and the target maintenance endpoint.

[0056] Furthermore, in one embodiment, step S20 further includes:

[0057] The status information of the vehicle component corresponding to the maintenance endpoint is obtained through the status flag bit carried in the message sent by each maintenance endpoint.

[0058] In this embodiment, during the Ethernet OAM communication process of each maintenance endpoint, each maintenance endpoint may carry a status flag in the message sent, where the status flag is used to indicate the current functional status of the maintenance endpoint, such as whether the current functional status is normal or abnormal or is in a certain type of fault. Since each vehicle component corresponds to a maintenance endpoint, the status information of the vehicle component corresponding to the maintenance endpoint can be determined by parsing the status flag carried in the message.

[0059] Further, in one embodiment, referring to Figure 3 , Figure 3 Another flow chart of an embodiment of the vehicle status detection method of the present application is as follows: Figure 3 As shown, after step S20, the following steps are included:

[0060] Step S30, displaying status information of multiple components on a vehicle instrument panel.

[0061] In this embodiment, the status information of multiple components is displayed on the vehicle instrument panel, so that the driver can understand and grasp the safety status of the vehicle in real time.

[0062] Furthermore, in one embodiment, the vehicle state detection method further includes:

[0063] Enable or disable the Ethernet OAM function according to the received instructions.

[0064] In this embodiment, the Ethernet OAM function is turned on or off according to the received instructions, which means that the Ethernet OAM function can be turned on or off according to the instructions, where the instructions can come from the driver and the network administrator, and can be sent to the Ethernet OAM in the form of a command line. After receiving the instructions, the Ethernet OAM controls the turning on or off of its own functions.

[0077] The source maintenance endpoint sends a loopback message to the target maintenance endpoint to detect the link status between the source maintenance endpoint and the target maintenance endpoint, so as to determine the communication status between the vehicle components respectively corresponding to the source maintenance endpoint and the target maintenance endpoint.
