Description

Communication method, device, storage medium and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 22, 2023, with application number 202311579173.9 and application name “A communication method and related device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to, but is not limited to, the field of vehicle communication technology, and in particular to a communication method, device, storage medium, and vehicle. Background Art

[0003] With the continuous development of intelligent connected vehicles and autonomous driving, the amount of communication data in vehicle networks is increasing rapidly, placing increasingly high demands on the reliability of controller data communication. When a vehicle communication network fails and data transmission is unable to proceed normally, communication redundancy design is required to ensure data transmission reliability.

[0004] In the related art, data that needs to be sent out through this network is not backed up and sent out through other networks, or data that multiple controllers need to send out is all sent out through multiple networks, which affects data transmission and poor user experience. Technical Solutions

[0005] Embodiments of the present application provide a communication method, apparatus, storage medium, and vehicle that, when the network status of a first network channel is abnormal, can determine the message type of a first message to be sent via the first network channel and send the first message via the first channel set or the second channel set. This ensures data redundancy and prevents a surge in network channel load, thereby improving the stability and reliability of data transmission and effectively enhancing the user experience.

[0006] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0007] In a first aspect, an embodiment of the present application provides a communication method, applied to a communication system, wherein the communication system includes N network channels, where N is an integer and N ≥ 3, and the method includes:

[0008] Acquire a first message, where the first message is assigned to be sent in a first network channel, and the first network channel is one of the N network channels;

[0009] Determining that a network status of the first network channel is abnormal;

[0010] If the message type of the first message is the first type, sending the first message through a first channel set, where the first channel set includes at least one network channel with a normal network status among the N network channels;

[0011] If the message type of the first message is the second type, the first message is sent through a second channel set, where the second channel set includes at least two network channels with normal network status among the N network channels, and the number of network channels included in the first channel set is less than the number of network channels included in the second channel set.

[0012] Optionally, the first message allocated to be sent in the first network channel includes messages that have not been sent yet and messages that have been sent successfully. The messages that have not been sent yet may also be messages scheduled to be sent in the first network channel.

[0013] In an embodiment of the present application, when the network status of the first network channel is abnormal, the communication system can send the first message through the first channel set or the second channel set based on the message type of the first message. For example, the message can be set to the first type or the second type, and different message types correspond to different backup sending methods.

[0014] In this way, for unimportant messages, their message type can be set to the first type, so that at least one is selected when sending in backup, for example, only one network channel with normal network status is selected for transmission, to avoid all network channels from backing up and sending the message, and to ensure that the load rate of the network channel will not surge. For more important messages, their message type can be set to the second type, so that at least two are selected when sending in backup, for example, all network channels with normal network status are selected for sending, thereby improving the success rate of message sending. In short, users can flexibly set the message type of the message and send the message in backup. On the one hand, it can prevent data loss and ensure the normal operation of the communication function. On the other hand, it can also ensure that the load rate of the network channel will not surge, ensuring data redundancy while improving the stability and reliability of data transmission, and effectively improving user experience.

[0015] In a possible implementation of the first aspect, the first type is a common message, and the second type is an important message.

[0016] In a possible implementation of the first aspect, the N network channels include the first network channel and at least one network channel having the same communication mode as the first network channel, and the communication mode of the network channels in the first channel set is the same as the communication mode of the first network channel.

[0017] In the above implementation, selecting a network channel with the same communication mode for data transmission can increase the speed of data transmission, and can also improve the stability and reliability of data transmission, which can effectively improve the user experience.

[0018] In a possible implementation manner of the first aspect, the first channel set includes all network channels among the N network channels, which have normal network status and the same communication mode as the first network channel.

[0019] In a possible implementation manner of the first aspect, the network channel in the first channel set is the network channel with the highest priority among the N network channels.

[0020] In this way, when the network status of the first network channel is abnormal, selecting a network channel with normal network status and the highest priority to send the first message can improve the stability and reliability of data transmission, and can also increase the speed of data transmission, which can effectively improve the user experience.

[0021] In another possible implementation manner of the first aspect, the network channel with the highest priority includes a network channel with the highest bit rate or the highest transmission rate among network channels with the same communication mode as the first network channel.

[0022] In this way, when the network status of the first network channel is abnormal, selecting a network channel with the same communication mode as the first network channel and the highest bit rate or the highest transmission rate to send the first message can improve the stability and reliability of data transmission, and can also increase the speed of data transmission, which can effectively improve the user experience.

[0023] In another possible implementation of the first aspect, at least two of the N network channels have the same communication mode as the first network channel, and the communication mode of the network channels in the second channel set is the same as the communication mode of the first network channel.

[0024] And / or, the N network channels include a network channel having a communication mode different from that of the first network channel, and the second channel set includes the network channels among the N network channels having a communication mode different from that of the first network channel.

[0025] In another possible implementation of the first aspect, the second channel set includes all network channels among the N network channels whose network status is normal and whose communication mode is the same as that of the first network channel.

[0026] In the above implementation, selecting a network channel with the same communication mode for data transmission can increase the speed of data transmission, and can also improve the stability and reliability of data transmission, which can effectively improve the user experience.

[0027] In another possible implementation manner of the first aspect, the N network channels include a network channel having a communication mode different from that of the first network channel.

[0028] The second channel set further includes at least one network channel among the N network channels, whose network status is normal and whose communication mode is different from that of the first network channel.

[0029] In another possible implementation of the first aspect, the communication mode of the first network channel is one of CAN communication, CAN-FD communication, Ethernet communication, and optical fiber communication.

[0030] In this way, data can be transmitted through multiple communication methods. When a certain communication method is abnormal, data can also be transmitted through other communication methods. This can improve the stability and reliability of data transmission and effectively improve user experience.

[0031] In another possible implementation manner of the first aspect, the abnormal network status includes one or more of error frames, message timeout, and bus OFF in the N network channels.

[0032] In this way, the network status of each network channel can be monitored in real time. When an abnormality occurs in a network channel, backup can be sent in time to ensure data redundancy while improving the stability and reliability of data transmission, which can effectively improve user experience.

[0033] In another possible implementation of the first aspect, the method further includes:

[0034] Obtaining a list of messages scheduled to be sent on the network channels in the first channel set;

[0035] The sending the first message through the first channel set includes:

[0036] In response to the presence of a second message with the same content as the first message in the message list, the earlier of the original scheduled sending time of the first message and the original scheduled sending time of the second message is used as the time for sending the second message, and the second message is sent through the first channel set.

[0037] In another possible implementation of the first aspect, the method further includes:

[0038] Obtaining a list of messages scheduled to be sent on the network channel in the second channel set;

[0039] The sending the first message through the second channel set includes:

[0040] In response to the presence of a third message with the same content as the first message in the message list, the earlier of the original scheduled sending time of the first message and the original scheduled sending time of the third message is used as the time for sending the third message, and the third message is sent through the second channel set.

[0041] In this way, when the message scheduled to be sent on the network channel with normal network status has the same content as the first message, it will not be sent repeatedly, which can avoid resource waste, prevent repeated operations, and effectively improve user experience.

[0042] In another possible implementation of the first aspect, the method further includes:

[0043] In response to the abnormal network status of the first network channel, determining a load rate of each of the N network channels, where the load rate is determined based on one or more of a communication mode of the network channel, a number of unsent messages of the network channel, an estimated time required for the network channel to send all messages, a bit rate of the network channel, a transmission rate of the network channel, and a message delay duration of the network channel;

[0044] The network channels in the first channel set are the network channels with the lowest load rate among the N network channels, and the network channels in the second channel set are the network channels with a load rate lower than a first threshold among the N network channels, where the first threshold is predefined or pre-set.

[0045] In this way, when the network status of the first network channel is abnormal, the load rate of each network channel is determined based on multiple influencing factors, and the network channel with the lowest load rate is selected to send the first message. This can improve the stability and reliability of data transmission, and can also increase the speed of data transmission, which can effectively improve the user experience.

[0059] In another possible implementation of the second aspect, the second channel set includes all network channels among the N network channels whose network status is normal and whose communication mode is the same as that of the first network channel.

[0060] In another possible implementation of the second aspect, the N network channels include a network channel having a communication mode different from that of the first network channel.

[0061] The second channel set further includes at least one network channel among the N network channels, whose network status is normal and whose communication mode is different from that of the first network channel.

[0089] Implementation Methods of the Application

[0090] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0091] The following is an introduction to the system architecture used in the embodiments of this application. It should be noted that the system architecture and business scenarios described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided by this application. It is understood by those skilled in the art that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by this application are equally applicable to similar technical problems.

[0092] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1, communication system 10 includes multiple network channels. Figure 1 uses network channel 1, network channel 2, network channel 3, and network channel n as examples. The following is an exemplary introduction to the communication system and network channels.

[0093] The communication system 10 is a device with data exchange and data processing capabilities. Optionally, the communication system 10 can obtain messages, process messages, and control network channels to send messages. Exemplarily, the communication system 10 can be a controller or an electronic device.

[0094] A network channel is a channel or medium with data transmission capability, and a network channel can be used to send messages outward. The communication system 10 may have multiple network channels, such as network channel 1, network channel 2, network channel 3, and network channel n in FIG1 . Optionally, the communication mode used by the network channel for data transmission may include one of CAN (Controller Area Network), CAN-FD (CAN with Flexible Data rate), Ethernet, and optical fiber, or a combination of the above communication modes. Exemplarily, the network channel may be a CAN channel, an Ethernet channel, an optical fiber channel, a CAN-FD channel, and the like. That is, there may be multiple ports on the communication system 10, for example, there may be multiple Ethernet ports or CAN ports and other ports on the communication system 10.

[0095] Optionally, the communication system 10 may include multiple network channels using the same communication method. That is, some of the multiple network channels included in the communication system 10 may use the same communication method. For example, the communication system 10 may include a total of five network channels, including three CAN network channels, two Ethernet channels, and five network channels of other network types.

[0096] Furthermore, network channels with the same communication mode can be network channels with different communication transmission parameters but the same communication mode. For example, network channels with the same communication mode can be CAN network channels with different baud rates or Ethernet channels with different speeds, such as a 100M Ethernet channel and a 1000M Ethernet channel.

[0097] As a possible implementation, the communication system 10 can obtain a first message assigned to be sent in the first network channel. When the communication system 10 determines that the network status of the first network channel is abnormal, if the message type of the first message is the first type, the first message is sent through the first channel set; if the message type of the first message is the second type, the first message is sent through the second channel set.

[0098] In an embodiment of the present application, the communication system can, when the network status of the first network channel is abnormal, send the first message through the first channel set or the second channel set according to the message type of the first message. In this way, for unimportant messages, the message type can be set to the first type, so that at least one is selected during backup transmission, for example, only one network channel with a normal network status is selected for transmission, to avoid all network channels from performing backup transmission of the message, thereby ensuring that the load rate of the network channel does not surge. For more important messages, the message type can be set to the second type, so that at least two are selected during backup transmission, for example, all network channels with normal network status are selected for transmission, thereby improving the success rate of message transmission. In short, users can flexibly set the message type of the message and send the message for backup. On the one hand, this can prevent data loss and ensure the normal operation of the communication function. On the other hand, it can also ensure that the load rate of the network channel does not surge, while ensuring data redundancy, it can improve the stability and reliability of data transmission and effectively improve user experience.

[0099] For example, consider the in-vehicle communication scenario. Due to the ongoing development of intelligent connected vehicles and autonomous driving, the volume of communication data on vehicle networks is surging, increasing the pressure on communication systems. When a vehicle communication network fails and data transmission is impossible, the communication system can select a network channel with a normal network status to send messages of the first type, and select all network channels with normal network status to send messages of the second type. This ensures data transmission reliability through communication redundancy design and avoids a surge in network channel load.

[0100] The method of the embodiment of the present application is described in detail below.

[0101] Please refer to Figure 2, which is a flow chart of a communication method provided in an embodiment of the present application. Optionally, the method can be applied to a communication system, for example, the method can be applied to the communication system 10 shown in Figure 1.

[0102] The communication method shown in FIG2 may include multiple steps in steps S201-S204. It should be understood that for the convenience of description, this application describes the steps S201-S204 in this order, and is not intended to limit the execution to the above order. The embodiment of this application does not limit the order of execution, execution time, number of executions, etc. of the above one or more steps. Steps S201-S204 are as follows:

[0103] Step S201: The communication system obtains a first message.

[0104] The first message is assigned to be sent on a first network channel, which is one of multiple network channels included in the communication system. Optionally, the first message assigned to be sent on the first network channel includes messages that have not yet been sent and messages that have been successfully sent. The messages that have not yet been sent may also be messages scheduled to be sent on the first network channel.

[0105] A communication system is a device with data exchange and data processing capabilities. Optionally, the communication system can obtain messages, process messages, and send messages through network channels. For example, the communication system can be a controller. The communication system can include multiple network channels, which can be used to send messages outward. For relevant introductions to the communication system, please refer to the relevant introduction of Figure 1. In some embodiments, the number of network channels included in the communication system is expressed as M, where M is an integer and M≥2, that is, M=2, M=3, etc. Optionally, in some embodiments, M can also be an integer and M≥3.

[0106] A network channel is a channel or medium capable of data transmission. The communication methods used for data transmission over a network channel can include one or more of CAN, CAN-FD, Ethernet, or fiber optics. When a communication system includes multiple communication methods, the system can transmit data through these methods. In the event of an anomaly in one communication method, data can be transmitted through other communication methods. This improves the stability and reliability of data transmission and effectively enhances the user experience.

[0107] Multiple network channels can be represented on a communication system through multiple ports. A port is an outlet for the communication system to communicate with the outside world and is used for communication. For example, a communication system may include multiple Ethernet ports or CAN ports.

[0108] Optionally, the communication modes of some of the M network channels included in the communication system may be the same. Furthermore, the network channels with the same communication mode may be network channels with different network channel parameters but the same communication mode.

[0109] Step S202: The communication system determines that the network status of the first network channel is abnormal.

[0110] During operation, a network channel may experience various network states, such as normal or abnormal. Abnormal conditions include, but are not limited to, one or more of the following: error frames, message timeouts, and bus OFFs. As one possible implementation, the communication system may monitor the network state of each of the multiple network channels to determine the network state.

[0111] When a network channel experiences an abnormality, the communication system needs to back up and send messages assigned to the first network channel over other network channels. During backup transmission, the message type is related to the backup transmission method. The message type can be represented by one or more attributes of the message, and messages can be classified into multiple types based on these attributes.

[0112] Taking the example of a message type including a first type and a second type, as a possible implementation, the message may include a first field. When the first field takes a first value, the message type is the first type; when the first field takes a second value, the message type is the second type. Furthermore, the message type can be determined by multiple attributes, for example, by combining the values ​​of the first field and the second field. When the first field takes the second value and the second field takes the third value, the message type is the first type. It is understandable that the first type and the second type in this application are exemplary descriptions made to distinguish different message types. During the specific implementation process, the first type can be an ordinary message, and the second type can be an important message (or called a special message). Optionally, in some scenarios, the first type may include more than one type, and the second type may also include more than one type.

[0113] The backup sending mode is described below in conjunction with step S203 and step S204, taking the case where the message type includes the first type and the second type as an example.

[0114] Step S203: If the message type of the first message is the first type, the communication system sends the first message through the first channel set.

[0115] Specifically, the first message is assigned to be sent on a first network channel. When the network status of the first network channel is abnormal, if the message type of the first message is a first type, the first message is sent via a first channel set, where the first channel set includes at least one network channel with a normal network status among a plurality of network channels included in the communication system.

[0116] For ease of understanding, several possible implementations of the first channel set are listed below:

[0117] In the first embodiment, the first channel set includes at least one network channel with a normal network status among multiple network channels. Please refer to Figure 3A, which is a schematic diagram of a network channel provided in an embodiment of the present application. For example, as shown in Figure 3A, the communication system includes network channels 1 to 4. When network channel 1 fails, the first channel set is at least one network channel with a normal network status among the remaining three network channels, that is, any one or any several network channels with a normal network status among network channels 2 to 4.

[0118] In the second embodiment, the first channel set includes network channels with the same communication mode as the first network channel. Among them, the multiple network channels include a first network channel and at least one network channel with the same communication mode as the first network channel. Please refer to Figure 3B, which is a schematic diagram of another network channel provided in an embodiment of the present application. For example, as shown in Figure 3B, the communication system includes network channels 1 to 4, wherein network channel 1 and network channel 3 are Ethernet channels, and network channel 2 and network channel 4 are CAN channels. When network channel 1 fails, the first channel set includes network channels with the same communication mode as the first network channel, that is, the first channel set includes network channel 3 in Figure 3B. In this way, selecting network channels with the same communication mode for data transmission can increase the speed of data transmission, and can also improve the stability and reliability of data transmission.

[0119] Furthermore, the first channel set includes all network channels among the multiple network channels that have normal network status and have the same communication mode as the first network channel.

[0120] Exemplarily, the communication system includes network channels 1 to 6, wherein network channel 1, network channel 3 and network channel 5 are Ethernet channels, and network channel 2, network channel 4 and network channel 6 are CAN channels. When network channel 1 fails, the first channel set includes all network channels with the same communication mode as the first network channel, that is, the first channel set includes network channel 3 and network channel 5.

[0121] In a third embodiment, the first channel set includes the network channel with the highest priority among the network channels with normal network status among the multiple network channels. Optionally, the communication system can prioritize each of the multiple network channels, and the network channel with the highest priority can be the network channel with the highest bit rate or the highest transmission rate among the network channels with the same communication mode as the first network channel. Please refer to Figure 3C, which is a schematic diagram of another network channel provided in an embodiment of the present application. For example, as shown in Figure 3C, the communication system includes network channels 1-network channels 4, wherein network channels 1-network channels 3 are Ethernet channels and network channel 4 is a CAN channel. When network channel 1 (i.e., a 100M Ethernet channel) fails, network channels 2-network channels 4 are in normal network status. The first channel set includes the network channel with the highest priority among network channels 2-network channels 4, for example, the network channel with a higher transmission rate among network channel 2 (i.e., a 300M Ethernet channel) and network channel 3 (i.e., a 1000M Ethernet channel), so the first channel set includes network channel 3 (i.e., a 1000M Ethernet channel) in Figure 3C.

[0122] Priority is a parameter used by the communication system to determine the priority of data transmission through one or more of multiple network channels. During backup transmission, the network channel with the highest priority can be selected for backup transmission. Optionally, the priority of the network channel can be pre-set by the user or determined based on network channel parameters.

[0123] For ease of understanding, Table 1 shows, by way of example, a priority table of multiple possible network channels.

[0124] Table 1 Priority table of multiple network channels

[0125] As shown in Table 1, the priority order of network channels is 1, 2, ..., n, and so on. For example, network channel 1 has a priority of 4, network channel 2 has a priority of 2, network channel 3 has a priority of 3, and network channel 4 has a priority of 1, among which network channel 4 has the highest priority. For example, when network channel 1 fails and the network communication status of network channels 2, 3, and 4 are all normal, since network channel 4 has the highest priority, the first message can be sent through network channel 4.

[0126] Optionally, there may be more than one network channel with the highest priority. In this case, the first channel set includes more than one network channel with the highest priority.

[0127] In this way, selecting the network channel with the highest priority to send the first message can improve the stability and reliability of data transmission and can also increase the speed of data transmission.

[0128] In a fourth embodiment, the first channel set may further include a network channel with the lowest load rate among the multiple network channels. Optionally, the communication system may determine the load rate of each network channel among the multiple network channels when the network status of the first network channel is abnormal. The communication system may determine the load rate of the network channel based on one or more of the communication mode of the network channel, the number of unsent messages of the network channel, the estimated time required for the network channel to send all messages, the bit rate of the network channel, the transmission rate of the network channel, and the message delay duration of the network channel. For example, please refer to Figure 3D, which is a schematic diagram of another network channel provided in an embodiment of the present application. For example, as shown in Figure 3D, the communication system includes five network channels, namely network channel 1 to network channel 5. Network channel 1 is abnormal. At this time, the network status of the remaining four network channels are normal, among which the load rate of network channel 2 is 30%, the load rate of network channel 3 is 50%, the load rate of network channel 4 is 70%, and the load rate of network channel 5 is 75%. At this time, the first channel set can also include network channel 2, that is, the first channel set includes network channel 2 in Figure 3D, and the communication system can send the first message through network channel 2.

[0129] In this way, the load rate of each network channel is determined according to multiple channel parameters, and the network channel with the lowest load rate is selected to send the first message, which can improve the stability and reliability of data transmission and also increase the speed of data transmission.

[0130] It should be understood that the above embodiments are illustrative examples, and there may be more embodiments in the specific implementation process. In addition, multiple embodiments may be combined.

[0131] Optionally, the network channels in the first channel set belong to multiple network channels, the network status of the network channels in the first channel set is normal, the network channels in the first channel set have the same communication mode as the first network channel, and the network channels in the first channel set have the lowest load rate among the network channels that meet the above conditions. In this way, when the network status of the first network channel is abnormal, selecting a network channel with the same communication mode as the first network channel and the lowest load rate to send the first message can better improve the stability and reliability of data transmission, better increase the speed of data transmission, and effectively improve the user experience.

[0132] As one possible implementation, a first message is a message scheduled to be sent via a first network channel at a first time. The message type of the first message is a first type. The communication system obtains a list of first messages scheduled to be sent via network channels in a first channel set. If a second message with the same content as the first message exists in the first message list, the communication system uses the earlier of the originally scheduled sending time of the first message and the originally scheduled sending time of the second message as the time to send the second message. The communication system sends the second message via the first channel set.

[0133] Exemplarily, the communication system detects that network channel 1 is abnormal at the 6th second, and network channel 2 is normal. The first channel set includes network channel 2. The communication system obtains message 1 scheduled to be sent through network channel 1 at the 10th second. The message type of message 1 is the first type. The communication system obtains the first message list scheduled to be sent through network channel 2. For example, the first message list includes message 2, message 3, and message 4. The communication system detects that message 2 has the same content as message 1. Message 2 is scheduled to be sent through network channel 2 at the 15th second. Between the 10th second and the 15th second, the 10th second is an earlier moment. At this time, the communication system controls network channel 2 to send message 2 at the 10th second.

[0134] As another example, the communication system detects an anomaly in network channel 1 at the 6th second, while network channels 2 and 3 are normal. The first channel set includes network channels 2 and 3. The communication system obtains message 1, scheduled to be sent via network channel 1 at the 10th second. Message 1 is of the first type. The communication system obtains a first message list scheduled to be sent via the first channel set, i.e., a first message list scheduled to be sent via network channels 2 and 3. For example, the first message list includes message 2, message 3, and message 4. The communication system detects that message 2 and message 4 have the same content as message 1. Message 2 is scheduled to be sent via network channel 2 at the 15th second, and message 4 is scheduled to be sent via network channel 3 at the 8th second. Since the 8th second is earlier than the 10th second, the 15th second, and the 8th second, the communication system controls network channel 2 to send message 2 at the 8th second and controls network channel 3 to send message 4 at the 8th second. In other words, for any network channel in a normal network state, messages with the same content are not sent repeatedly.

[0135] In this way, when the message scheduled to be sent on the network channel with normal network status has the same content as the first message, it will not be sent repeatedly, which can avoid resource waste, prevent repeated operations, and effectively improve user experience.

[0136] Step S204: If the message type of the first message is the second type, the communication system sends the first message through the second channel set.

[0137] Step S204 introduces another backup transmission method. When the network status of the first network channel is abnormal, if the message type of the first message is of the second type, the first message is sent via the second channel set. The second channel set includes at least two network channels with normal network status from the multiple network channels included in the communication system. Exemplarily, the number of network channels in the second channel set is represented by K, where K is an integer greater than 1. It should be noted that the number of network channels included in the first channel set is smaller than the number of network channels included in the second channel set.

[0138] For ease of understanding, several possible implementations of the second channel set are listed below:

[0139] In the first embodiment, the second channel set includes at least two network channels with normal network status among the multiple network channels. For example, the second channel set includes all network channels with normal network status among the multiple network channels. Exemplarily, as shown in FIG3A , the communication system includes network channels 1 to 4. When network channel 1 fails, the second channel set includes all network channels with normal network status among the remaining three network channels, that is, the second channel set includes two or all of network channels 2 to 4 in FIG3A . For another example, the communication system includes 10 network channels, and network channel 1 is abnormal. At this time, the network status of the remaining nine network channels is normal. At this time, the second channel set can include two or all of the remaining nine network channels. In this way, the transmission success rate of the first message can be improved.

[0140] It should be noted that in order to facilitate the explanation of the different backup sending methods, K is limited to an integer greater than 1. In some possible scenarios, if the communication system only includes the first network channel and the third network channel, when the first network channel fails, all network channels with normal network status are only one third network channel, and the second channel set includes this third network channel, that is, this solution is also applicable to the case where K=1.

[0141] In the second embodiment, the communication mode of the network channels in the second channel set is the same as the communication mode of the first network channels.

[0142] Exemplarily, the communication system includes M network channels, at least two of which have the same communication mode as the first network channel, for example, N of the M network channels have the same communication mode as the first network channel.

[0143] Furthermore, the second channel set includes all network channels with normal network status among the N network channels, where N is an integer and N≥3.

[0144] In this case, M and N may be the same or different. When M>N, there is a network channel among the M network channels that uses a different communication method than the N network channels. For example, as shown in FIG3C , a communication system includes network channels 1 through 4, where network channels 1 through 3 are Ethernet channels and network channel 4 is a CAN channel. Network channels 1 through 3 use the same communication method. When network channel 1 fails, network channels 2 through 4 remain in a normal state. The second channel set includes the network channels among network channels 1 through 3 that have a normal network state, i.e., the second channel set includes network channels 2 and 3 in FIG3C . For another example, a communication system includes 10 network channels, with network channel 1 failing. At this time, the remaining nine network channels all have normal network states. Of the remaining nine network channels, three use the same communication method as network channel 1. In this case, the second channel set can include these three network channels that use the same communication method as network channel 1. In this way, selecting network channels with the same communication method for data transmission can increase the speed of data transmission and improve the stability and reliability of data transmission.

[0145] Furthermore, the second channel set includes network channels that have a different communication method from the first network channel. For example, when M>N, that is, among the M network channels, there is also a network channel that has a different communication method from the N network channels. In this case, the second channel set includes at least one network channel that has a different communication method from the first network channel, or the second channel set includes the N network channels and at least one network channel that has a different communication method from the first network channel. For example, the communication system includes 10 network channels, and network channel 1 is abnormal. At this time, the network status of the remaining 9 network channels are normal, among which 3 of the remaining 9 network channels have the same communication method as network channel 1. In this case, the second channel set can include these 3 network channels that have the same communication method as network channel 1, and / or the second channel set can include at least one network channel among the remaining 6 network channels.

[0146] In a third embodiment, the second channel set may further include a network channel whose load rate among the multiple network channels is lower than the first threshold. Optionally, the communication system may determine the load rate of each network channel among the multiple network channels when the network status of the first network channel is abnormal. The communication system may determine the load rate of the network channel based on one or more of the communication mode of the network channel, the number of unsent messages of the network channel, the estimated time required for the network channel to send all messages, the bit rate of the network channel, the transmission rate of the network channel, and the message delay time of the network channel. Optionally, the first threshold is used to indicate the condition that the load rate of the network channel needs to meet. The first threshold is predefined or pre-specified. For example, the first threshold may be a value lower than 60%, such as 55%, 40%, etc. Exemplarily, as shown in Figure 3D, the communication system includes 5 network channels, namely network channel 1 to network channel 5, and network channel 1 is abnormal. At this time, the network status of the remaining 4 network channels are normal, among which the load rate of network channel 2 is 30%, the load rate of network channel 3 is 50%, the load rate of network channel 4 is 70%, and the load rate of network channel 5 is 75%. The first threshold is a value lower than 60%. At this time, the second channel set can include network channel 2 and network channel 3.

[0147] In this way, the load rate of each network channel is determined according to multiple influencing factors, and a network channel with a load rate lower than a first threshold is selected to send the first message, which can improve the stability and reliability of data transmission and also increase the speed of data transmission.

[0148] It should be understood that the above embodiments are illustrative examples, and there may be more embodiments in the specific implementation process. In addition, multiple embodiments may be combined.

[0149] Optionally, the network channels in the second channel set belong to multiple network channels, the network status of the network channels in the second channel set is normal, the network channels in the second channel set have the same communication mode as the first network channel, and the network channels in the second channel set are network channels with a load rate lower than the first threshold among the network channels that meet the above conditions. In this way, when the network status of the first network channel is abnormal, selecting a network channel with the same communication mode as the first network channel and a load rate lower than the first threshold to send the first message can better improve the stability and reliability of data transmission, better increase the speed of data transmission, and effectively improve the user experience.

[0150] As one possible implementation, a first message is a message scheduled to be sent via a first network channel at a first time. The message type of the first message is a second type. The communication system obtains a list of second messages scheduled to be sent via a network channel in a second channel set. If a third message with the same content as the first message exists in the second message list, the communication system uses the earlier of the originally scheduled sending time of the first message and the originally scheduled sending time of the third message as the time to send the third message. The communication system sends the third message via the second channel set.

[0151] Exemplarily, the communication system includes 4 network channels. The communication system detects that network channel 1 is abnormal at the 6th second, and network channel 2, network channel 3 and network channel 4 are normal. The communication system obtains message 1 scheduled to be sent through network channel 1 at the 10th second. The message type of message 1 is the second type. The communication system obtains a second message list scheduled to be sent through network channel 2, network channel 3 and network channel 4. For example, the second message list includes 10 messages, namely message 2, message 3, message 4 and message 5. Among them, the communication system detects that message 4 has the same content as message 1. Message 4 is scheduled to be sent through network channel 3 at the 8th second. Between the 8th second and the 10th second, the 8th second is an earlier moment. At this time, the communication system controls network channel 3 to send message 4 at the 8th second.

[0152] As another example, the communication system detects an anomaly in network channel 1 at the 6th second, while network channels 2 and 3 are normal. The first channel set includes network channels 2 and 3. The communication system obtains message 1, scheduled to be sent via network channel 1 at the 10th second. Message 1 is of the first type. The communication system obtains a second message list, scheduled to be sent via network channels 2, 3, and 4. For example, the second message list includes 10 messages, namely, message 2, message 3, message 4, and message 5. The communication system detects that message 4 and message 6 have the same content as message 1. Message 4 is scheduled to be sent via network channel 3 at the 8th second, and message 6 is scheduled to be sent via network channel 4 at the 12th second. Since the 8th second is earlier than the 8th second, the 10th second, and the 12th second, the communication system controls network channel 3 to send message 4 at the 8th second and controls network channel 4 to send message 6 at the 8th second. In other words, for any network channel with a normal network status, messages with the same content are not sent repeatedly.

[0153] In this way, when the message scheduled to be sent on the network channel with normal network status has the same content as the first message, it will not be sent repeatedly, which can avoid resource waste, prevent repeated operations, and effectively improve user experience.

[0154] As a possible implementation method, when M=2, if network channel 1 is abnormal, regardless of whether the first message is of the first type or the second type, the communication system will back up and send the first message through network channel 2. At this time, the network channels selected by the two backup methods of the communication system for the first message of the first type and the first message of the second type are the same, but the selection logic corresponding to the two backup methods is different.

[0155] In the embodiment shown in FIG2 , when the network status of the first network channel is abnormal, the communication system can, based on the message type of the first message, send the first message through the first channel set or the second channel set. Thus, for unimportant messages, their message type can be set to the first type, so that at least one is selected during backup transmission, for example, only one network channel with a normal network status is selected for transmission, thereby preventing all network channels from performing backup transmission of the message and ensuring that the network channel load rate does not surge. For more important messages, their message type can be set to the second type, so that at least two are selected during backup transmission, for example, all network channels with normal network status are selected for transmission, thereby improving the success rate of message transmission. In short, users can flexibly set the message type of messages and back up the messages. This can prevent data loss and ensure the normal operation of communication functions on the one hand, and ensure that the network channel load rate does not surge on the other hand, ensuring data redundancy while improving the stability and reliability of data transmission, effectively improving the user experience.

[0156] The embodiment shown in FIG2 includes multiple possible solutions. For ease of understanding, one possible solution is described below. It should be understood that some of the terms and logic in the solution shown in FIG4 can refer to the embodiment shown in FIG2.

[0157] Please refer to Figure 4, which is a flow chart of another communication method provided in an embodiment of the present application. The method includes the following steps:

[0158] S1: The communication system divides the message types of the messages to be sent out into a first type and a second type.

[0159] The first type is different from the second type. Optionally, the second type may be a message of higher importance or a message selected by the user.

[0160] S2: The communication system determines the priorities of multiple network channels included in the communication system.

[0161] In some embodiments, the communication system may include M network channels, where M is an integer and M≥2, that is, M=2, M=3, etc. Optionally, in some embodiments, M may also be an integer and M≥3.

[0162] Optionally, the communication system may determine the priority of the network channel based on one or more of the communication mode of the network channel, the number of unsent messages of the network channel, the time expected to be required for the network channel to send all messages, the bit rate of the network channel, the transmission rate of the network channel, and the message delay duration of the network channel.

[0163] S3: The communication system monitors the network status of each network channel in real time.

[0164] When the network status of the network channel is normal, step S4 is executed; when the network status of the network channel is abnormal, step S5 is executed.

[0165] The abnormal network status includes one or more of the following abnormal conditions: error frames, message timeouts, and bus OFF in multiple network channels.

[0166] S4: The communication system sends a message through the logic control network channel according to the predetermined normal state.

[0167] S5: The communication system sends the message according to the abnormal state. If the message type of the message is the first type, the message is sent through the network channel with the highest priority that is of the same type and in normal network status. If the message type is the second type, the message is sent through multiple network channels of the same type and in normal network status.

[0168] The network channels of the same type may be network channels with the same communication mode.

[0169] In the embodiment shown in FIG4 , the communication system can classify the message types of messages to be sent out into a first type and a second type, and determine the priorities of multiple network channels included in the communication system. The communication system can monitor the network status of each network channel in real time. When the network status is normal, the message is sent according to a predetermined normal state sending logic. When the network status is abnormal, the message is sent according to an abnormal state. If the message type of a message is the first type, the message is sent via the highest priority network channel with the same communication mode as the network channel and the normal network status. If the message type of a message is the second type, the message is sent via multiple network channels with the same communication mode as the network channel and the normal network status. In this way, the first message can be backed up and sent, preventing data loss and ensuring the normal operation of the communication function. It can also ensure that the load rate of the network channel does not surge, ensuring data redundancy while improving the stability and reliability of data transmission, effectively enhancing the user experience.

[0170] The above describes in detail the method of the embodiment of the present application. The following provides an apparatus of the embodiment of the present application.

[0171] Please refer to Figure 5, which is a schematic diagram of the structure of a processing device provided in an embodiment of the present application. The processing device 50 may include an acquisition device 501 and a processor 502. The processing device 50 is used to implement the aforementioned communication method, such as the communication method in the embodiments shown in Figures 2 and 4.

[0172] In a possible implementation, the processing device is included in a communication system, and the communication system includes N network channels, where N is an integer and N≥3.

[0173] The acquisition device 501 is used to obtain a first message, where the first message is assigned to be sent in a first network channel, and the first network channel is one of the N network channels;

[0174] The processor 502 is configured to:

[0176] If the message type of the first message is the first type, sending the first message through the first channel set, where the first channel set includes at least one network channel with a normal network status among the N network channels;

[0177] If the message type of the first message is the second type, the first message is sent through the second channel set, the second channel set includes at least 2 network channels with normal network status among the N network channels, and the number of network channels included in the first channel set is less than the number of networks included in the second channel set.

[0178] In a possible implementation, the first type is a common message, and the second type is an important message.

[0179] In a possible implementation, the N network channels include a first network channel and at least one network channel having the same communication mode as the first network channel, and the communication mode of the network channels in the first channel set is the same as that of the first network channel.

[0180] In a possible implementation, the first channel set includes all network channels among the N network channels, which have normal network status and the same communication mode as the first network channel.

[0181] In a possible implementation, the network channel in the first channel set is the network channel with the highest priority among the N network channels.

[0182] In a possible implementation, the network channel with the highest priority includes a network channel with the highest bit rate or the highest transmission rate among network channels with the same communication mode as the first network channel.

[0183] In a possible implementation, at least two of the N network channels have the same communication mode as the first network channel, and the communication mode of the network channels in the second channel set is the same as the communication mode of the first network channel.

[0184] And / or, the N network channels include a network channel having a communication mode different from that of the first network channel, and the second channel set includes the network channels among the N network channels having a communication mode different from that of the first network channel.

[0186] In a possible implementation, the N network channels include a network channel having a communication mode different from that of the first network channel.

[0187] The second channel set further includes at least one network channel among the N network channels, whose network status is normal and whose communication mode is different from that of the first network channel.

[0188] In a possible implementation, the communication mode of the first network channel is one of CAN communication, CAN-FD communication, Ethernet communication, and optical fiber communication.

[0189] In a possible implementation manner, the abnormal network status includes one or more of the following: error frames occurring in N network channels, message timeout, and bus OFF.

[0190] In a possible implementation, the acquisition device 501 is further configured to obtain a list of messages scheduled to be sent on the network channel in the first channel set;

[0191] The processor 502 is also used to, when there is a second message with the same content as the first message in the message list, use the earlier of the original scheduled sending time of the first message and the original scheduled sending time of the second message as the time for sending the second message, and send the second message through the first channel set.

[0192] In a possible implementation, the acquisition device 501 is further configured to obtain a list of messages scheduled to be sent on the network channel in the second channel set;

[0193] The processor 502 is also used to, when there is a third message with the same content as the first message in the message list, use the earlier of the original scheduled sending time of the first message and the original scheduled sending time of the third message as the time for sending the third message, and send the third message through the second channel set.

[0194] In one possible implementation, the processor 502 is further configured to, when the network status of the first network channel is abnormal, determine a load rate of each of the N network channels, where the load rate is determined based on one or more of a communication mode of the network channel, a number of unsent messages of the network channel, an estimated time required for the network channel to send all messages, a bit rate of the network channel, a transmission rate of the network channel, and a message delay duration of the network channel.

[0195] The second network channel is the network channel with the lowest load rate among the N network channels, and the multiple third network channels are network channels with load rates lower than a first threshold among the N network channels. The first threshold is predefined or pre-set.
