[0002] The current car gateway routing is achieved by building a static routing table in the car gateway.

Once there are new signals in the ECU (Electronic Control Unit) under the vehicle gateway, it is necessary to update the communication matrix table and regenerate the static routing table used by the vehicle gateway; and the static routing table is hard-coded into the vehicle gateway code, so the vehicle gateway program needs to be upgraded again at this time.

[0045] The current car gateway routing is achieved by building a static routing table in the car gateway. When the car gateway receives a CAN message from a CAN channel, it directly queries the static routing table to obtain the destination channel corresponding to the message, and then sends it out from the destination channel.

[0046] This implementation has the following problems:

[0047] 1. The generation of static routing tables is rather troublesome. It is necessary to determine all signal forwarding paths when designing the vehicle network, form a standard communication matrix table, and then use tools to convert the matrix table into a static routing table for vehicle gateway forwarding, and finally load the table into the vehicle gateway.

[0048] 2. The maintenance of static routing tables is troublesome. Once there is a new signal in the ECU connected to the car gateway, the communication matrix table needs to be updated and the static routing table used by the car gateway needs to be regenerated. In many cases, the static routing table is hard-coded into the car gateway code, and the car gateway program needs to be upgraded again. This will lead to a complex version management problem. The software versions of each ECU of the whole vehicle, the versions of the communication matrix table, and the versions of the car gateway program need to be consistent, which is very costly to maintain and prone to errors.

[0049] 3. When matching a new car model, the car gateway program needs to be modified and adapted more because the communication matrix table has changed a lot.

[0050] Based on the above-mentioned defects, this application proposes a new dynamic routing system for automobile gateways, which replaces the implementation method of static routing tables by automatic registration, thereby solving the defects caused by static routing table technology. In this method, since the routing information is not set in advance, it is called dynamic routing, but it is quite different from traditional dynamic routing. Traditional dynamic routing usually uses routing protocols to publish node information to the routing domain by flooding, thereby realizing the release of routing information. However, this application only requires the ECU to register the CAN_ID it needs to the automobile gateway, build a routing information table in the automobile gateway, and guide message forwarding.

[0051] Figure 1 This is a simplified schematic diagram of the network topology of the automotive electronic and electrical architecture, which is only used to illustrate the design ideas of this application. Figure 1 The car gateway in the figure contains a dynamic routing table, which is represented by a dotted box. The dynamic routing table has the same function as the previous static routing table, which is used to guide message forwarding. The difference is that the static routing table is fixed, and the dynamic routing table is registered by the ECU to the car gateway after the car gateway and the downstream ECU are started.

[0052] See also Figure 1 , this embodiment provides a vehicle gateway dynamic routing system, including: a vehicle gateway and at least one electronic control unit (hereinafter referred to as ECU to represent the electronic control unit), the vehicle gateway includes at least one data transmission channel, and the electronic control unit is connected to the at least one data transmission channel;

[0053] The automobile gateway includes a dynamic routing table, which includes an association relationship between an electronic control unit and a data transmission channel; the automobile gateway is used to complete data transmission between a source electronic control unit and a target electronic control unit based on the dynamic routing table;

[0054] In an embodiment of the present application, the dynamic routing table is obtained by registering the association between the logical address of the electronic control unit and the data transmission channel, wherein the logical address of the electronic control unit is obtained by parsing the registration request message carrying the logical address of the electronic control unit received by the automobile gateway.

[0055] In a vehicle network, each ECU has a unique logical address, which is used to identify and distinguish different ECUs in the network. This logical address is usually determined during the hardware or firmware design phase of the ECU and programmed into the ECU during the production process. For example, the logical address of the engine control unit (ECU-Engine) in a smart car is "0x01", which is written into the ECU in advance.

[0056] When an ECU is first connected to the vehicle network or needs to be re-registered (for example, after a software update), a registration request message is constructed after the automotive gateway and ECU are started. This message contains the logical address of the ECU (such as CANID), and possibly other necessary information, such as the type of ECU, the supported communication protocol version, security credentials (such as encryption keys or certificates), etc. The ECU sends the registration request message to the automotive gateway in the vehicle network through its communication interface (such as CAN interface, Ethernet interface, etc.). The automotive gateway is a key device in the vehicle network, responsible for data forwarding and routing management between different network segments.

[0057] After receiving the registration request message from the ECU, the automotive gateway parses the registration request message to obtain the logical address and other relevant information of the ECU in the registration request message. Then the logical address of the ECU in the received request message is associated with the data transmission channel (such as a specific CAN ID range, Ethernet port or VLAN) to form an association relationship, and then the association relationship is registered to obtain a dynamic routing table. This dynamic routing table is the basis for the automotive gateway to make data packet forwarding decisions. It contains information such as the logical addresses, supported communication protocols, and data transmission channels of all ECUs in the network.

[0058] When the source ECU needs to access the target ECU, the corresponding target data transmission channel can be determined through the CANID and dynamic routing table of the target ECU, and the source ECU obtains the corresponding data from the target ECU through the target data transmission channel.

[0059] In the embodiment of the present application, the routing system further includes: a non-volatile memory for storing the dynamic routing table.

[0060] When the car gateway is reset due to some abnormal reason, the previous dynamic routing table information will be lost. This problem can be solved by writing the dynamic routing table to FLASH. FLASH usually refers to the flash memory in the microcontroller. It is a non-volatile memory used to store program code and some resident numbers. The data will not be lost even after power failure. When the car gateway starts, it first loads the dynamic routing information from FLASH, and then receives the request from the downstream ECU for real-time update, which can also speed up the construction of the dynamic routing table.

[0061] The present application replaces the implementation method of the static routing table by automatic registration, thereby solving the defects of the static routing table in that the construction and maintenance are troublesome.

[0062] See also Figure 2 , Figure 2 Flow chart of a method for constructing a dynamic routing table according to an embodiment of the present application. Figure 2 As shown, a method for constructing a dynamic routing table includes steps S210 to S230:

[0063] Step S210, sending a registration request message to the automobile gateway, wherein the registration request message carries the logical address of the electronic control unit;

[0064] In a vehicle network, each ECU has a unique logical address, which is used to identify and distinguish different ECUs in the network. This logical address is usually determined during the hardware or firmware design phase of the ECU and programmed into the ECU during the production process. For example, the logical address of the engine control unit (ECU-Engine) in a smart car is "0x01", which is written into the ECU in advance.

[0065] When an ECU is first connected to the vehicle network or needs to be re-registered (for example, after a software update), a registration request message is constructed after the automotive gateway and ECU are started. This message contains the logical address of the ECU (such as CANID), and possibly other necessary information, such as the type of ECU, the supported communication protocol version, security credentials (such as encryption keys or certificates), etc. The ECU sends the registration request message to the automotive gateway in the vehicle network through its communication interface (such as CAN interface, Ethernet interface, etc.). The automotive gateway is a key device in the vehicle network, responsible for data forwarding and routing management between different network segments.

[0066] Step S220, receiving and parsing the registration request message to obtain the logical address of the electronic control unit, associating the logical address of the electronic control unit with the data transmission channel and registering them to obtain a dynamic routing table;

[0067] After receiving the registration request message from the ECU, the automotive gateway parses the registration request message to obtain the logical address and other relevant information of the ECU in the registration request message. Then the logical address of the ECU in the received request message is associated with the data transmission channel (such as a specific CAN ID range, Ethernet port or VLAN) to form an association relationship, and then the association relationship is registered to obtain a dynamic routing table. This dynamic routing table is the basis for the automotive gateway to make data packet forwarding decisions. It contains information such as the logical addresses, supported communication protocols, and data transmission channels of all ECUs in the network.

[0068] During the registration process, the automotive gateway may also perform security checks to verify the identity and permissions of the ECU to ensure that only legitimate ECUs can access the network and participate in communications.

[0069] Figure 3 FIG. 1 is a functional block diagram of a dynamic routing system for an automobile gateway according to an embodiment of the present application. Figure 3As shown, the two channels channel1 and channel2 of the car gateway are connected to ECU1-1, ECU1-2 and ECU2-1, ECU2-2 respectively. Assume that ECU1-1 needs to receive the message of CANID1-1, ECU1-2 needs to receive the message of CANID1-2, ECU2-1 needs to receive the message of CANID2-1, and ECU2-2 needs to receive the message of CANID2-2.

[0070] It should be noted that the message ID that an ECU needs to receive is determined when the vehicle network is designed. Often an ECU needs to receive more than one message type, and the message type can be identified by CANID.

[0071] It should be noted that an ECU can correspond to more than one data transmission channel. When ECUs located in different channels initiate registration requests for the same CANID to the automotive gateway, multiple destination channels will be created in the same entry in the dynamic routing table. Table 1 shows the table structure of the dynamic routing table, indicating that an ECU can correspond to multiple data transmission channels.

[0072] Table 1

[0073] Destination CAN_ID Destination Channel CAN_ID1 Channel1_1[,Channel1_2,…Channel1_N] CAN_ID2 Channel2_1[,Channel2_2,…Channel2_N]

[0074] Step S230: Send a registration success message to the ECU.

[0075] After the automotive gateway completes the creation of the dynamic routing table, it generates a successful registration message and then returns the successful registration message to the ECU.

[0076] Once the logical address of the ECU is successfully registered in the dynamic routing table and all necessary checks have passed, the automotive gateway will generate a successful registration message. This successful registration message will be sent back to the ECU that initiated the registration request, notifying it that it has successfully registered in the vehicle network and can start normal communication activities. After the ECU receives the successful registration message, the ECU will confirm and update its internal state, preparing for subsequent data transmission and communication tasks.

[0077] After successful registration, the automotive gateway will continue to monitor the communication activities in the network and perform operations such as route optimization, fault detection and recovery as needed to ensure the stable operation of the vehicle network. The automotive gateway may also maintain an online status list of ECUs to record which ECUs are currently active and which may have failed or disconnected, so that corresponding processing can be performed when necessary.

[0078] The present application replaces the implementation method of the static routing table by automatic registration, thereby solving the defects of the static routing table in that the construction and maintenance are troublesome.

[0079] In one embodiment of the present application, the method further includes: if the ECU does not receive a registration success message returned by the automobile gateway within a set time period, sending a registration request message to the automobile gateway again through the ECU.

[0080] If the ECU starts and initializes before the car gateway, the registration request message sent by the ECU may be lost, so the ECU will continue to send registration request messages before receiving the registration success message from the car gateway. Specifically, after the CAN driver in the ECU is initialized, a timer task can be started to send a registration request to the car gateway. After receiving the registration success message, the timer task is closed. If no registration success message is received, the timer task will be executed continuously.

[0081] In one embodiment, the association relationship between the electronic control unit and the data transmission channel includes:

[0082] The association between an electronic control unit and a data transmission channel;

[0083] The association between an electronic control unit and multiple data transmission channels.

[0084] When an ECU is associated with a data transmission channel, it means that the ECU sends data outward through the data transmission channel, or receives data sent by other ECUs.

[0085] When an ECU is associated with multiple data transmission channels, it means that the ECU will send data outward through the multiple data transmission channels, or receive data sent by multiple other ECUs.

[0086] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0087] See also Figure 4 , Figure 4 Flow chart of a data processing method according to an embodiment of the present application. Figure 4 As shown, a data processing method includes:

[0088] Step S410, receiving a request message sent by a source electronic control unit through a vehicle gateway, wherein the request message carries a logical address of a target electronic control unit;

[0089] Step S520, parsing the request message to obtain the logical address of the target electronic control unit, and determining the target data transmission channel based on the logical address of the target ECU and a dynamic routing table; wherein the dynamic routing table is constructed by the aforementioned method for constructing the dynamic routing table;

[0090] In one embodiment of the present application, the step of determining the target data transmission channel based on the logical address of the target electronic control unit and the dynamic routing table includes:

[0091] Calling the dynamic routing table;

[0092] Based on the logical address of the target ECU, the dynamic routing table is queried to obtain the logical address of the corresponding target ECU through the association between the logical address of the ECU and the data transmission channel, and determine the target data transmission channel.

[0093] When the car gateway receives a CAN message from the ECU, it will query the dynamic routing table and match the CAN_ID of the message with the destination CAN_ID in the table. Since the dynamic routing table records the association between the logical address (CAN_ID) and the data transmission channel, if the match is successful, the corresponding target data transmission channel can be determined, and then the data can be sent out from the corresponding target data transmission channel.

[0094] Often, the target data transmission channel may be one or more than one.

[0095] For example, when source ECU-1 wants to obtain data from target ECU-2, source ECU-1 sends a request message carrying the logical address of target ECU-2 to the vehicle gateway; the vehicle gateway parses the request message to obtain the logical address of target ECU-2, and determines the target data transmission channel based on the logical address of target ECU-2 and the dynamic routing table;

[0096] When source ECU-1 wants to obtain data from target ECU-2 and target ECU-3 at the same time, source ECU-1 sends a request message carrying the logical addresses of target ECU-2 and target ECU-3 to the automotive gateway; the automotive gateway parses the request message to obtain the logical addresses of target ECU-2 and target ECU-3, and determines the target data transmission channel based on the logical addresses of target ECU-2 and target ECU-3 and the dynamic routing table, that is, the data transmission channel corresponding to target ECU-2 and the data transmission channel corresponding to target ECU-3.

[0097] Step S430: sending data from the source electronic control unit to the target electronic control unit through the target data transmission channel.
