[0037] In this embodiment, the structure of the vehicle communication system is as follows: Figure 1 See Figure 1The vehicle communication system includes a first communication node, a second communication node, a first channel and a second channel.

[0038] Reference Figure 1 , the first communication node and the second communication node may respectively include a microcontroller unit (MCU), and the first channel and the second channel may be channels based on different communication protocols, specifically, a wired channel or a wireless channel. For example, in this embodiment, the first channel is a controller area network bus (Controller Area Network, CAN), and the second channel is an in-vehicle Ethernet. In order to communicate through the first channel and the second channel, refer to Figure 1 The first communication node and the second communication node are respectively provided with a CAN controller for communicating through a first channel and an Ethernet controller for communicating through a second channel.

[0039] In this embodiment, the first channel and the second channel are both duplex channels, that is, the first communication node can send data to the second communication node through the first channel, and vice versa, the second communication node can send data to the first communication node through the first channel; similarly, the first communication node can send data to the second communication node through the second channel, and vice versa, the second communication node can send data to the first communication node through the second channel.

[0040] In this embodiment, the first communication node is used as a node that is sending data, and the second communication node is used as a node that is receiving data.

[0041] In this embodiment, the communication between the first communication node and the second communication node may be point-to-point, for example, the first communication node is a certain vehicle-mounted component (or a component of a component), and the second communication node is another vehicle-mounted component (or a component of a component), and communication is performed between the two vehicle-mounted components; the communication between the first communication node and the second communication node may also be in the form of a bus, for example Figure 2 As shown, the first communication node and the second communication node are common communication nodes, which are respectively connected to a plurality of vehicle-mounted components such as control devices, sensor devices and communication devices, thereby forming a bus for communication between these devices.

[0042] In this embodiment, when the vehicle-mounted communication system is working, the first communication node obtains the first data to be sent, such as A, B, C, D, and E. In this embodiment, A, B, C, D, and E can be in units of bits, bytes, data frames, messages, data packets, or processes, for example, A, B, C, D, and E can be respectively one bit, one byte, one data frame, one message, one data packet, or all data from the same software process or hardware, etc.

[0043] In this embodiment, the first communication node sends first data to be sent, such as A, B, C, D, and E, to the second communication node through the first channel; at the same time, the first communication node obtains the second data to be sent A' corresponding to the first data to be sent A, the second data to be sent B' corresponding to the first data to be sent B, the second data to be sent C' corresponding to the first data to be sent C, the second data to be sent D' corresponding to the first data to be sent, and the second data to be sent E' corresponding to the first data to be sent E, and sends the second data to be sent, such as A', B', C', D', and E', to the second communication node through the second channel.

[0044] In this embodiment, the first communication node can copy the first data to be sent A, B, C, D, E, etc., respectively, so as to obtain the second data to be sent A', B', C', D', E'. For example, the first communication node runs the communication middleware to copy the first data to be sent A, so as to obtain the corresponding second data to be sent A'. The second data to be sent A', B', C', D', E' obtained in this way are respectively the same as the corresponding first data to be sent A, B, C, D, E.

[0045] In this embodiment, the first communication node can compress the first data to be sent A, B, C, D, E, etc. respectively, so as to obtain the second data to be sent A', B', C', D', E'. For example, the first data to be sent A, B, C, D, E is data in image or audio format. The first communication node runs the communication middleware and compresses the first data to be sent A through an image compression algorithm or an audio compression algorithm, so as to obtain the corresponding second data to be sent A'. Although the second data to be sent A', B', C', D', E' obtained in this way are not completely the same as the corresponding first data to be sent A, B, C, D, E, they contain similar information, and the second communication node may decompress the received second data to be sent A', B', C', D', E' to obtain the same data as the first data to be sent A, B, C, D, E.

[0046] In this embodiment, by setting the first channel and the second channel, the first communication node can send the first data to be sent to the second communication node through the first channel, and send the second data to be sent to the second communication node through the second channel, wherein the second data to be sent is obtained by means of copying or compression and corresponds to the first data to be sent. In this way, the second communication node can obtain multiple copies of data corresponding to the first data to be sent through multiple channels. In this way, when a certain channel fails, the second communication node may still obtain the data corresponding to the first data to be sent, thereby improving the stability of communication; since there are more channels to ensure the transmission of data, the extra time consumption for waiting for recovery when a single channel fails is reduced, which is beneficial to reducing data transmission delay.

[0047] In this embodiment, after receiving the first data to be sent and the corresponding second data to be sent, the second communication node retains one of the data and discards the other.

[0048] For example, after receiving the first data to be sent A and the corresponding second data to be sent A', the second communication node retains the first data to be sent A and discards the second data to be sent A', or retains the second data to be sent A' and discards the first data to be sent A. Specifically, the second communication node can obtain the reception time of the first data to be sent A and the second data to be sent A'. If it is determined according to the reception time that the first data to be sent A is received first and the second data to be sent A' is received later, then the second communication node retains the first data to be sent A and discards the second data to be sent A'.

[0049] By having the second communication node retain one of the data and discard the other data, multiple transmission and selective reception of data between the first communication node and the second communication node can be achieved, thereby improving the utilization rate of the channel bandwidth and optimizing the data transmission delay.

[0050] In this embodiment, when the first communication node sends each first to-be-sent data to the second communication node through the first channel, the following steps are specifically performed:

[0051] S1A. Detect the current driving task information of the car;

[0052] S2A obtains the correlation between each first data to be sent and the current driving task information;

[0053] S3A sorts the first data to be sent in descending order according to the degree of association;

[0054] S4A. Form a first sending queue with the sorted first data to be sent, and send it to the second communication node through the first channel.

[0055] In step S1A, the first communication node can detect the current driving task information of the vehicle where the on-board communication system is located from the vehicle management system, where the current driving task information represents information related to the driving task currently being performed by the vehicle where the on-board communication system is located, such as real-time driving speed, driving mode (automatic driving or manual driving), component usage status (for example, the car headlights are currently in use), etc.

[0056] In step S2A, the first communication node respectively detects the correlation between the first data to be sent A and the current driving task information, the correlation between the first data to be sent B and the current driving task information, the correlation between the first data to be sent C and the current driving task information, the correlation between the first data to be sent D and the current driving task information, and the correlation between the first data to be sent E and the current driving task information.

[0057] In step S3A, the first communication node sorts the first data to be sent A, B, C, D, and E in descending order according to the correlation obtained in step S2A. In this embodiment, it is assumed that the sorted first data to be sent are A, B, C, D, and E, that is, the correlation between the first data to be sent A and the current driving task information is the highest, the correlation between the first data to be sent B and the current driving task information is the second highest, the correlation between the first data to be sent C and the current driving task information is the third highest, the correlation between the first data to be sent D and the current driving task information is the second lowest, and the correlation between the first data to be sent E and the current driving task information is the lowest.

[0058] In step S4A, the first communication node forms a first transmission queue with the first data to be transmitted A, B, C, D, and E in the order of A, B, C, D, and E, and transmits the first data to be transmitted to the second communication node through the first channel in this order. Specifically, the first communication node first transmits the first data to be transmitted A to the second communication node through the first channel, and after transmitting the first data to be transmitted A, transmits the first data to be transmitted B to the second communication node through the first channel, and after transmitting the first data to be transmitted B, transmits the first data to be transmitted C to the second communication node through the first channel... Finally, transmits the first data to be transmitted E to the second communication node through the first channel.

[0059] In this embodiment, the principle of executing steps S1A-S4A is that the correlation between the first data to be sent and the current driving task information indicates the correlation between the first data to be sent and the current driving task (for example, if the specific content of the current driving task information is "turn on the headlights", the correlation between the first data to be sent A with the specific content of "left headlight failure" and the current driving task information will be higher than the correlation between the first data to be sent B with the specific content of "image captured by the front camera" and the current driving task information). The first sending queue obtained by this sorting will enable the first communication node to preferentially send the first data to be sent with a high correlation with the current driving task through the first channel, thereby providing data transmission services for the current driving task and reducing the possibility that the current driving task cannot obtain necessary data due to excessive transmission delay or channel failure.

[0060] In this embodiment, when the first communication node sends each second to-be-sent data to the second communication node through the second channel, the first communication node specifically performs the following steps:

[0061] S1B. Get the maximum value of all associations;

[0062] S2B. When the maximum value of all associations is greater than or equal to the threshold, the first transmission mode is selected, otherwise, the second transmission mode is selected;

[0063] S3B. When the first transmission mode is selected, the second data to be transmitted are sorted in the same order according to the order of the first data to be transmitted in the first transmission queue;

[0064] S4B. The sorted second data to be sent form a second transmission queue, which is sent to the second communication node through the second channel;

[0065] S5B. When the second transmission mode is selected, the order of each first data to be transmitted in the first transmission queue is used as the reference sorting, and the reference sorting is performed out of order to obtain out of order sorting;

[0066] S6B sorts the second data to be sent according to the out-of-order sorting;

[0067] S7B. Form a second sending queue with the sorted second data to be sent, and send it to the second communication node through the second channel.

[0068] In step S1B, the maximum value of all the associations is obtained and compared with a preset threshold. In this embodiment, a fixed threshold is set. If the maximum value of all the associations is greater than or equal to the threshold, it can be determined that "the maximum value of all the associations is larger". On the contrary, if the maximum value of all the associations is less than the threshold, it can be determined that "the maximum value of all the associations is smaller".

[0069] In step S2B, if it is determined that "the maximum value of all associations is greater than or equal to the threshold", that is, "the maximum value of all associations is larger", then the first communication node chooses to execute the first sending mode, that is, jumps to execute steps S3B-S4B; conversely, if it is determined that "the maximum value of all associations is less than the threshold", that is, "the maximum value of all associations is smaller", then the first communication node chooses to execute the second sending mode, that is, jumps to execute steps S5B-S7B.

[0070] In this embodiment, if the first communication node chooses to execute the first sending mode, that is, to execute steps S3B-S4B, then refer to Figure 3 In step S3B, the first communication node sorts the second data to be sent in the same order as the first data to be sent in the sorted first sending queue, that is, A, B, C, D, E; for example, the first data to be sent A is ranked first in the first sending queue, and the second data to be sent A' corresponding to the first data to be sent A is also ranked first in the second sending queue, the first data to be sent B is ranked second in the first sending queue, and the second data to be sent B' corresponding to the first data to be sent B is also ranked second in the second sending queue... Thus, the second data to be sent are arranged in the second sending queue in the order of A', B', C', D', E'.

[0071] In step S4B, the first communication node sends to the second communication node through the second channel in the order A', B', C', D', E' in the second sending queue. Specifically, the first communication node can simultaneously send the first data to be sent A, B, C, D, E through the first channel, and send the second data to be sent in the order of A', B', C', D', E' through the second channel, that is, the first communication node can simultaneously send the first data to be sent A and the second data to be sent A', and after completing the sending, simultaneously send the first data to be sent B and the second data to be sent B'...

[0072] In this embodiment, if the first communication node chooses to execute the second sending mode, that is, to execute steps S5B-S7B, then refer to Figure 4In step S5B, the first communication node uses the order of the first data to be sent in the first sending queue, that is, A, B, C, D, E, as the reference order, performs random reordering on the reference order, and obtains a random order. Figure 4 As shown, A, B, C, D, and E are reordered (only to obtain a different order, not to perform actual data reordering on the first sending queue), and the obtained reorder is B, A, D, E, C, that is, the first data to be sent C ranks first in the reorder, and the second data to be sent C' corresponding to the first data to be sent C also ranks first in the second sending queue; the first data to be sent E ranks second in the reorder, and the second data to be sent E' corresponding to the first data to be sent E also ranks second in the second sending queue...Thus, step S6B is executed to arrange the second data to be sent into the second sending queue in the order of C', E', D', A', and B'.

[0073] Specifically, when executing step S5B to perform random reordering on the benchmark order, the random ordering can be obtained by random reordering. For example, taking A, B, C, D, E as the benchmark ordering, in addition to the possibility of obtaining the above-mentioned random ordering such as B, A, D, E, C, it is also possible to obtain a random ordering such as D, A, B, C, E or B, D, E, A, C; the random ordering can also be obtained by reverse reordering. For example, taking A, B, C, D, E as the benchmark ordering, the reverse order can be obtained, that is, E, D, C, B, A, as the random ordering.

[0074] In step S7B, the first communication node sends to the second communication node through the second channel in the order C', E', D', A', B' in the second sending queue. Specifically, the first communication node can simultaneously send the first data to be sent A, B, C, D, E through the first channel, and send the second data to be sent through the second channel in the order of C', E', D', A', B', that is, the first communication node can simultaneously send the first data to be sent A and the second data to be sent C', and after completing the sending, simultaneously send the first data to be sent B and the second data to be sent E'...

[0075] In this embodiment, the principle of executing steps S1B-S7B is that: when it is determined that "the maximum value of all correlations is greater than or equal to the threshold value", that is, "the maximum value of all correlations is larger", it indicates that "there is data with a larger correlation with the current driving task in the first data to be sent / the second data to be sent to be sent", that is, the data to be sent is required by the current driving task, then the first sending mode is executed. In the first sending mode, the first communication node sends each first data to be sent and each second data to be sent to the second communication node through the first channel and the second channel in the same corresponding order, so that it can be ensured that each data to be sent is sent in the order of correlation from high to low, and the sending order of the first channel and the second channel is the same, which can ensure the success rate of data sending; when it is determined that "the maximum value of all correlations is greater than or equal to the threshold value", it indicates that "there is data with a larger correlation with the current driving task in the first data to be sent / the second data to be sent to be sent", that is, the data to be sent is required by the current driving task, then the first sending mode is executed. In the first sending mode, the first communication node sends each first data to be sent and each second data to be sent to the second communication node through the first channel and the second channel in the same corresponding order, so that it can be ensured that each data to be sent is sent in the order of correlation from high to low, and the sending order of the first channel and the second channel is the same, which can ensure the success rate of data sending; is less than the threshold value", that is, when "the maximum value of all correlations is small", it indicates that "the first data to be sent / the second data to be sent to be sent have a small correlation with the current driving task", that is, the data to be sent may not be urgently needed for the current driving task, then the second sending mode is executed. In the second sending mode, the first communication node sends each first data to be sent and each second data to be sent to the second communication node through the first channel and the second channel respectively in a corresponding different order, so that the first data to be sent and the second data to be sent sent by the first channel and the second channel in the same time period are different, so that the first channel and the second channel form a parallel channel, which can increase the data sending rate of the first channel and the second channel combined, thereby quickly sending each first data to be sent and each second data to be sent to the second communication node.

[0076] In this embodiment, the first communication node can only set the first sending mode, so that when the first communication node sends each second data to be sent to the second communication node through the second channel, it is not necessary to execute steps S1B-S2B and S5B-S7B, and there is no need to determine whether to execute the first sending mode, and steps S3B-S4B can be directly executed; the first communication node can also only set the second sending mode, so that when the first communication node sends each second data to be sent to the second communication node through the second channel, it is not necessary to execute steps S1B-S4B, and there is no need to determine whether to execute the second sending mode, and steps S5B-S7B can be directly executed.

[0077] In this embodiment, the vehicle-mounted communication system can be installed on the car, making the vehicle-mounted communication system an integral part of the car, so that the car has the effects of strong communication stability of vehicle-mounted components and low transmission delay data.
