It can be understood that the onboard terminal 110 is not necessarily a single electronic device, but may also be any collection of devices or circuits that can execute the above-mentioned computer program alone or in combination.

[0040] In the vehicle terminal 110, the processor 10 may include a central processing unit (CPU), a graphics processing unit (GPU), a programmable logic device, a dedicated processor system, a microcontroller or a microprocessor. As an example but not limitation, the processor 10 may also include an analog processor, a digital processor, a microprocessor, a multi-core processor, a processor array or a network processor, etc.

[0041] In the vehicle-mounted terminal 110, the processor 10 can run a computer program stored in the memory 20, which can be divided into one or more modules / units (such as computer program 1, computer program 2, ...), and the one or more modules / units are stored in the memory 20 and executed by the processor 10 to complete the present invention.

[0044] In a specific example, the vehicle terminal 110 may be, but is not limited to, a vehicle controller (VCU). The above is only a specific example and is flexibly configured according to user needs in actual applications and is not limited here.

[0045] In one embodiment, Figure 2 As shown, a vehicle bus routing control method is provided, and the method is applied to Figure 1 The vehicle-mounted terminal 110 is taken as an example to illustrate, including the following steps 201 to 204.

[0046] Step 201, obtaining a dynamic routing table of the current working condition of the vehicle.

[0047] Among them, the vehicle operating conditions include static state, started but not driven state and driving state; the current vehicle operating condition is the vehicle operating condition at the current moment. Specifically, the dynamic routing table is used to count the node parameter information of each node in the vehicle topology diagram. It is understandable that the node parameter information of each node in the dynamic routing table will be dynamically updated in real time. The vehicle topology diagram is used to describe the entire topology of the vehicle network. Different nodes correspond to different vehicle equipment. In a specific example, the vehicle equipment includes a vehicle stability system, an electric power steering module, an airbag module, an engine control system, a battery sensor, a dual-clutch transmission, a direction rotation sensor, a mobile headlight, an intelligent entry and start system, a steering column lock, a speed limit display system, an instrument, a power management system, a body controller, an automatic zoned air conditioner, 3G, DVD, a radio, GPS and a seat module audio and video entertainment system. The above is only a specific example, which is flexibly set according to user needs in actual applications and is not limited here.

[0048] Specifically, the node parameter information of each node includes the bus load rate of the corresponding node, the routing priority from the corresponding node to the corresponding next node, the message data from the corresponding node to the corresponding next node, the communication fault diagnosis parameters from the corresponding node to the corresponding next node, and the node function parameter array from the corresponding node to the corresponding next node. The node function parameter array includes the function parameters of each node from the corresponding node to the corresponding next node. Characterizing the function parameters of each node by the node function parameter array can reduce the number of times the node parameter information is sent and improve the bus utilization. The vehicle terminal 110 can obtain the dynamic routing table of the current working condition of the vehicle.

[0049] In a specific example, the node parameter information of each node also includes the node name of the corresponding node, the node address of the corresponding node, the node name of each next node of the corresponding node, and the node address of each next node of the corresponding node. Specifically, the node address is a node address code, and the smaller the node address code number, the higher the corresponding routing priority. Node function parameters include current monitoring values ​​and voltage monitoring values, etc. In addition, the number of the next node of each node can be one or more. The above is only a specific example, which is flexibly set according to user needs in actual applications and is not limited here.

[0050] In one embodiment, if Figure 3 As shown, obtaining a dynamic routing table of the current working condition of the vehicle includes steps 301 to 303.

[0051] Step 301, obtaining the current working condition of the vehicle, the vehicle topology diagram and the communication demand information of each node.

[0052] Step 302: Analyze the vehicle topology diagram and each communication demand information to obtain parameter information of each node.

[0053] Step 303: Generate a dynamic routing table based on the current working condition of the vehicle and parameter information of each node.

[0054] Specifically, the vehicle terminal 110 obtains the current operating condition of the vehicle, the vehicle topology diagram and the communication demand information of each node; then, the vehicle topology diagram and the communication demand information are analyzed to obtain the parameter information of each node; then, a dynamic routing table is generated according to the current operating condition of the vehicle and the parameter information of each node, thereby improving the convenience and efficiency of obtaining the dynamic routing table of the current operating condition of the vehicle.

[0055] In this embodiment, the current operating condition of the vehicle, the vehicle topology diagram and the communication demand information of each node are obtained; then, the vehicle topology diagram and the communication demand information are analyzed to obtain the parameter information of each node; then, a dynamic routing table is generated according to the current operating condition of the vehicle and the parameter information of each node, thereby improving the convenience and efficiency of obtaining the dynamic routing table of the current operating condition of the vehicle.

[0056] In one embodiment, if Figure 3 As shown, obtaining a dynamic routing table of the current working condition of the vehicle also includes step 300.

[0057] Step 300, in response to the upload operation of the vehicle demand file, the vehicle demand file is screened and processed to obtain the vehicle topology diagram and various communication demand information.

[0058] Specifically, when uploading the vehicle demand file, the vehicle terminal 110 performs information screening on the vehicle demand file to obtain the vehicle topology diagram and various communication demand information, thereby improving the efficiency and convenience of obtaining the vehicle topology diagram and various communication demand information.

[0059] In this embodiment, in response to the upload operation of the whole vehicle demand file, the whole vehicle demand file is screened and processed to obtain the whole vehicle topology structure diagram and various communication demand information, thereby improving the efficiency and convenience of obtaining the whole vehicle topology structure diagram and various communication demand information.

[0060] Step 202, obtain the current node and the corresponding target next node of the statistical vehicle topology diagram, query and process the node parameter information corresponding to the current node according to the current node and the target next node to obtain the target fault diagnosis parameters, and determine whether there is a communication fault from the current node to the target next node according to the target fault diagnosis parameters.

[0061] The target next node is the next node corresponding to the current highest routing priority of the current node. The target fault diagnosis parameter is the communication fault diagnosis parameter corresponding to the current node to the target next node.

[0062] Specifically, the vehicle terminal 110 obtains the current node and the corresponding target next node of the statistical vehicle topology structure diagram, obtains the target fault diagnosis parameters after querying and processing the node parameter information corresponding to the current node according to the current node and the target next node, and determines whether there is a communication failure from the current node to the target next node based on the target fault diagnosis parameters.

[0063] In one embodiment, if Figure 4 As shown, obtaining the target next node corresponding to the current node includes steps 401 to 405.

[0064] Step 401, obtaining the current next node corresponding to the current node.

[0065] Step 402: Query and process the node parameter information corresponding to the current node according to the current node and the current next node corresponding to the current node to obtain the second target routing priority.

[0066] Step 403: Determine whether the second target routing priority is the current highest routing priority of the current node.

[0067] Step 404: If the second target routing priority is the current highest routing priority of the current node, the current next node corresponding to the current node is determined as the target next node.

[0068] Step 405: If the second target routing priority is not the current highest routing priority of the current node, determine the target next node according to the current highest routing priority of the current node.

[0069] Among them, the second target routing priority is the routing priority from the current node to the current next node corresponding to the current node. Specifically, the current next node corresponding to the current node is obtained; then, the second target routing priority is obtained after querying and processing the node parameter information corresponding to the current node according to the current node and the current next node corresponding to the current node; then, it is determined whether the second target routing priority is the current highest routing priority of the current node; then, if the second target routing priority is the current highest routing priority of the current node, the current next node corresponding to the current node is determined as the target next node; finally, if the second target routing priority is not the current highest routing priority of the current node, the target next node is determined according to the current highest routing priority of the current node, which improves the efficiency and convenience of obtaining the target next node corresponding to the current node.

[0070] In this embodiment, the current next node corresponding to the current node is obtained; then, the second target routing priority is obtained after querying the node parameter information corresponding to the current node based on the current node and the current next node corresponding to the current node; then, it is determined whether the second target routing priority is the current highest routing priority of the current node; then, if the second target routing priority is the current highest routing priority of the current node, the current next node corresponding to the current node is determined as the target next node; finally, if the second target routing priority is not the current highest routing priority of the current node, the target next node is determined according to the current highest routing priority of the current node, thereby improving the efficiency and convenience of obtaining the target next node corresponding to the current node.

[0071] Step 203, if there is no communication failure from the current node to the target next node, the target bus load rate is obtained by querying the node parameter information corresponding to the current node according to the current node, and it is determined whether the target bus load rate is greater than the load rate threshold.

[0072] The target bus load rate is the bus load rate of the current node. When there is no communication failure from the current node to the target next node, the vehicle terminal 110 obtains the target bus load rate after querying the node parameter information corresponding to the current node according to the current node, and determines whether the target bus load rate is greater than the load rate threshold.

[0073] Step 204: if the target bus load rate is less than the load rate threshold, the current node is controlled to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node.

[0074] Specifically, when the target bus load rate is less than the load rate threshold, the vehicle terminal 110 controls the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, thereby achieving that when the bus load rate is low and there is no communication failure, the current node with the highest routing priority can obtain bus access rights to send messages, thereby improving real-time performance and reliability.

[0075] In the above-mentioned vehicle bus routing control method, a dynamic routing table of the current working condition of the vehicle is obtained; the dynamic routing table is used to count the node parameter information of each node in the vehicle topology diagram; the node parameter information includes the bus load rate of the corresponding node, the routing priority from the corresponding node to the corresponding next node, the message data from the corresponding node to the corresponding next node, the communication fault diagnosis parameters from the corresponding node to the corresponding next node, and the node function parameter array from the corresponding node to the corresponding next node; the node function parameter array includes the node function parameters from the corresponding node to the corresponding next node; then, the current node and the corresponding target next node of the statistical vehicle topology diagram are obtained, and the target fault diagnosis parameters are obtained after querying the node parameter information corresponding to the current node according to the current node and the target next node, and it is judged whether there is a connection from the current node to the target next node according to the target fault diagnosis parameters. Communication failure; the target next node is the next node corresponding to the current highest routing priority of the current node; the target fault diagnosis parameter is the communication fault diagnosis parameter corresponding to the current node to the target next node; then, if there is no communication failure from the current node to the target next node, the target bus load rate is obtained after querying the node parameter information corresponding to the current node according to the current node, and it is determined whether the target bus load rate is greater than the load rate threshold; the target bus load rate is the bus load rate of the current node; finally, if the target bus load rate is less than the load rate threshold, the current node is controlled to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, so that when the bus load rate is low and there is no communication failure, the current node with the highest routing priority can obtain bus access rights to send messages, thereby improving real-time performance and reliability.

[0076] In one embodiment, if Figure 5 As shown, after controlling the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, it also includes steps 501 and 502.

[0077] Step 501, querying and processing the node parameter information corresponding to the current node according to the current node to obtain the routing priorities of the current node, and judging whether there are the eliminated routing priorities according to the routing priorities of the current node.

[0078] Among them, the routing priorities after elimination are the routing priorities of the current node after eliminating the current highest routing priority of the current node; the vehicle terminal 110 obtains the routing priorities of the current node after querying and processing the node parameter information corresponding to the current node according to the current node, and determines whether there are routing priorities after elimination according to the routing priorities of the current node.

[0079] Step 502, if there are routing priorities after elimination, update the current highest routing priority of the current node according to the routing priorities after elimination, update the target next node according to the current highest routing priority of the current node, and return to the node parameter information corresponding to the current node according to the current node and the target next node to obtain the target fault diagnosis parameters after querying and processing.

[0080] Specifically, when there are various routing priorities after elimination, the vehicle terminal 110 updates the current highest routing priority of the current node according to the various routing priorities after elimination, updates the target next node according to the current highest routing priority of the current node, and returns to the step of obtaining the target fault diagnosis parameters after querying and processing the node parameter information corresponding to the current node according to the current node and the target next node, so that each routing priority is controlled by the vehicle bus routing in turn, which improves the convenience and efficiency of the vehicle bus reason control and ensures reliability.

[0081] In this embodiment, after querying the node parameter information corresponding to the current node according to the current node, the routing priorities of the current node are obtained, and it is determined whether there are routing priorities after elimination according to the routing priorities of the current node; then, if there are routing priorities after elimination, the current highest routing priority of the current node is updated according to the routing priorities after elimination, and the target next node is updated according to the current highest routing priority of the current node, and the target fault diagnosis parameters are obtained after querying the node parameter information corresponding to the current node according to the current node and the target next node, so that the routing priorities are controlled in turn by the vehicle bus routing, which improves the convenience and efficiency of the vehicle bus reason control and ensures reliability.

[0082] In one embodiment, if Figure 5 As shown, the node parameter information also includes a node name of the corresponding node, a node address of the corresponding node, a node name of the next node of the corresponding node, and a node address of the next node of the corresponding node;

[0083] Among them, after controlling the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, it also includes:

[0084] Step 503, if the routing priorities after elimination do not exist, the current node is updated to the target next node, and the target next node corresponding to the current node is obtained after querying the node parameter information corresponding to the current node according to the current node, and returns to the target fault diagnosis parameters obtained after querying the node parameter information corresponding to the current node according to the current node and the target next node.

[0085] Specifically, when the routing priorities after elimination do not exist, the vehicle-mounted terminal 110 updates the current node to the target next node, obtains the target next node corresponding to the current node after querying the node parameter information corresponding to the current node according to the current node, and returns to obtain the target fault diagnosis parameters after querying the node parameter information corresponding to the current node according to the current node and the target next node, thereby completing the update of the current node, improving the convenience and efficiency of vehicle bus reason control, and ensuring reliability.

[0086] In this embodiment, if the routing priorities after elimination do not exist, the current node is updated to the target next node, and the target next node corresponding to the current node is obtained after querying the node parameter information corresponding to the current node according to the current node, and then returned to the target fault diagnosis parameters obtained after querying the node parameter information corresponding to the current node according to the current node and the target next node, thereby completing the update of the current node, improving the convenience and efficiency of vehicle bus reason control, and ensuring reliability.

[0087] In one embodiment, if Figure 6 As shown, the method further includes step 601.

[0088] Step 601, if there is a communication failure from the current node to the target next node, the routing priority corresponding to the current node to the target next node is adjusted to the current lowest routing priority of the current node, and returned to the routing priorities of the current node obtained after querying the node parameter information corresponding to the current node according to the current node.

[0089] Specifically, when there is a communication failure from the current node to the next target node, the vehicle-mounted terminal 110 adjusts the routing priority corresponding to the current node to the next target node to the current lowest routing priority of the current node, and returns to the routing priorities of the current node obtained after querying the node parameter information corresponding to the current node according to the current node, thereby avoiding the communication failure from the current node to the next target node affecting the normal sending of message data by other nodes in the vehicle topology diagram, thereby improving reliability.

[0090] In this embodiment, if there is a communication failure from the current node to the next target node, the routing priority corresponding to the current node to the next target node is adjusted to the current lowest routing priority of the current node, and returned to the current node after querying the node parameter information corresponding to the current node to obtain the routing priorities of the current node, thereby avoiding the communication failure from the current node to the next target node affecting the normal sending of message data by other nodes in the vehicle topology diagram, thereby improving reliability.

[0091] In one embodiment, if Figure 6 As shown, the method further includes step 602.

[0092] Step 602, if the target bus load rate is greater than or equal to the load rate threshold, the routing priority corresponding to the current node to the target next node is adjusted to the second target routing priority, and returned to the routing priorities of the current node obtained after querying the node parameter information corresponding to the current node according to the current node.

[0093] Among them, the second routing priority is a routing priority one level lower than the current highest routing priority of the current node. When the target bus load rate is greater than or equal to the load rate threshold, the vehicle terminal 110 adjusts the routing priority corresponding to the current node to the target next node to the second target routing priority, and returns to the current node after querying the node parameter information corresponding to the current node to obtain the routing priorities of the current node, so that the current node sends the message data and node function parameter array corresponding to the current node to the target next node in the second routing priority, dynamically adjusts the route, avoids retransmission and collision caused by high load, reduces the probability of collision and retransmission, and improves reliability.

[0094] In this embodiment, if the target bus load rate is greater than or equal to the load rate threshold, the routing priority corresponding to the current node to the target next node is adjusted to the second target routing priority, and returned to the current node after querying the node parameter information corresponding to the current node to obtain the routing priorities of the current node, so that the current node sends the message data and node function parameter array corresponding to the current node to the target next node in the second routing priority, dynamically adjusts the route, avoids retransmission and collision caused by high load, reduces the probability of collision and retransmission, and improves reliability.

[0095] In one embodiment, if Figure 7 As shown, the method further includes step 701.

[0096] Step 701 , when controlling the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, monitor and feed back the target bus load rate and target fault diagnosis parameters.

[0097] Specifically, when the vehicle-mounted terminal 110 controls the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, it monitors and feeds back the target bus load rate and target fault diagnosis parameters, so that debugging and optimization can be performed based on the feedback target bus load rate and target fault diagnosis parameters, thereby ensuring the reliability and scalability of the technology.

[0098] In this embodiment, when controlling the current node to send the message data and node function parameter array corresponding to the current node to the target next node to the target next node, the target bus load rate and target fault diagnosis parameters are monitored and fed back, so that debugging and optimization can be performed based on the feedback target bus load rate and target fault diagnosis parameters, thereby ensuring the reliability and scalability of the technology.

[0099] It should be understood that although Figure 2-7 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.
