[0029] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0031] As described in the related art, a master node and multiple slave nodes equipped on a vehicle for realizing the keyless entry function often use the LIN protocol for communication. However, the LIN protocol has the defect of low transmission rate. When a large amount of information is transmitted between the master node and the slave node, the information needs to be divided into multiple frames and then transmitted on the LIN network, which makes the communication timeliness between the master node and the slave node poor.

[0032] In order to solve the problems in the prior art, the embodiments of the present application provide a vehicle information configuration method, a slave node, a master node and a vehicle. The vehicle information configuration method provided by the embodiments of the present application is first introduced below.

[0033] In order to solve the problem of poor timeliness when the master node and the slave node communicate using the LIN protocol, a communication protocol with a transmission rate higher than the LIN protocol can be used, such as the CAN (Controller Area Network) protocol and the CANFD (CAN with Flexible Data-Rate) protocol.

[0034] However, since protocols such as CAN or CANFD do not have the function of configuring the node identity (ID), and considering the production line assembly requirements of the master node and the slave node, it is also impossible to pre-configure the identity of the slave node before the master and slave nodes are assembled and networked. Therefore, before the master and slave nodes communicate using protocols such as CAN or CANFD, the configuration problem of the identity used by the slave node for communication needs to be solved. In addition, in order not to affect the positioning of the car key, the master node also needs to be able to identify the installation location of the slave node.

[0035] It should be noted that the reason why the identity of the slave node cannot be configured in advance before the master and slave nodes are assembled and networked is that when the master node locates the car key, it needs to know the installation position of the slave node in advance, so that the slave node close to the car key can be located based on the signal strength sent by each slave node. However, since the node devices used as slave nodes are all universal devices, if the identity of the node device is configured in advance before assembly, it is difficult to ensure that the node device is installed in the installation position corresponding to the identity, which will lead to subsequent car key positioning errors. In addition, even if the slave nodes are divided into different batches in advance according to different vehicle positions, and the identity of the corresponding vehicle position is pre-set for the same batch, it is easy to assemble incorrectly during assembly due to the same appearance of the slave node devices, and it is impossible to ensure that the node device is installed in the installation position corresponding to the identity. Therefore, it is necessary to configure the identity of the slave node after the master and slave nodes are assembled and networked.

[0036] In this regard, an embodiment of the present application provides a vehicle information configuration method to solve the configuration problem of the identity identifier used for communication by the slave node after changing the communication protocol, thereby solving the problem of poor timeliness when the master node and the slave node communicate using the LIN protocol.

[0037] See also Figure 1 , which shows an implementation flow chart of the vehicle information configuration method provided in an embodiment of the present application. The vehicle information configuration method can be implemented by a slave node, and the communication network composed of a master node and at least one slave node adopts a preset communication protocol. Specifically, the preset communication protocol can be a protocol with a transmission rate higher than the local interconnection network protocol, such as the CAN protocol or the CANFD protocol. It should be noted that the communication network is a network for information exchange between the master node and the slave node, whether it is the information exchange during the identity configuration process or the subsequent information exchange for the keyless entry function, all are carried out in the communication network.

[0038] like Figure 1 As shown, the vehicle information configuration method includes the following processing:

[0039] Step 110: When the slave node is powered on for the first time after being assembled, the slave node detects whether the communication network is connected.

[0040] After the master node and at least one slave node are assembled in the vehicle, such as in the assembly stage of the production line, the slave node can be powered on. In this way, when the slave node detects that it is powered on for the first time, the slave node can execute a built-in program to detect whether the communication network is connected, and perform corresponding processing according to the detection result.

[0041] In some embodiments, the vehicle can be any type of vehicle, such as a gasoline vehicle, a diesel vehicle, or other vehicles with a fuel system, or a new energy vehicle such as an EV (Electric Vehicle), an HEV (Hybrid Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle).

[0042] Step 120: When the communication network is not connected, when the slave node receives a preset number corresponding to the installation position of the slave node sent by the vehicle diagnostic device via contactless communication, the slave node configures its own identity in the communication network according to the preset number.

[0043] In some embodiments, the contactless communication connection can be any contactless type of communication connection, such as NFC (Near Field Communication) connection or RFID (Radio Frequency Identification) connection. Accordingly, the slave node needs to be a node device with contactless communication function, such as Figure 2 As shown, a communication network is provided, which includes a master node and three slave nodes with NFC function.

[0044] When the slave node detects that the communication network is not connected, it indicates that it is in the initial configuration stage. At this time, the slave node waits for a signal that triggers it to perform identity identification configuration processing, which can be a connection signal of the vehicle diagnostic device. Specifically, when the vehicle diagnostic device receives an identity configuration instruction, such as a configuration operation instruction input by a production line worker on the display interface of the vehicle diagnostic device, the vehicle diagnostic device can establish a non-contact communication connection with each slave node respectively, such as the production line worker can place the vehicle diagnostic device near each slave node in a certain order. Taking a vehicle equipped with 5 slave nodes as an example, assuming that the installation positions of the 5 slave nodes are the main driver's door, the co-driver's door, the rear left door, the rear right door and the trunk door, non-contact communication connections can be established with the 5 slave nodes in a clockwise order, starting from the slave node installed on the main driver's door. When the vehicle diagnostic device establishes a non-contact connection with a slave node, the vehicle diagnostic device can authenticate the identity of the slave node to determine whether the slave node is a node device corresponding to the vehicle to be installed. When the authentication is passed, the vehicle diagnostic device will write the preset number corresponding to the installation position of the slave node into the slave node. Still taking the above-mentioned vehicle equipped with 5 slave nodes as an example, the preset numbers corresponding to different installation positions can be pre-configured, such as the numbers 1, 2, 3, 4, and 5 can be configured in the order of the main driver's door, the co-driver's door, the rear left door, the rear right door, and the trunk door. It should be noted that the numbers 1-5 are only for examples, and the purpose of configuring the numbers is to refer to the installation position of the slave node. Therefore, any digital information that can refer to the installation position of the slave node can be used as a number.

[0045] In this way, the slave node can receive the preset number corresponding to its installation position. In this way, the slave node can obtain the preset identity corresponding to the preset number, such as Ox01, according to the preset correspondence relationship of the preset identity corresponding to the preset number stored in advance, and configure the preset identity as its identity in the communication network. In this way, the problem that communication protocols such as CAN cannot configure the identity of the node is solved, so that the slave node using communication protocols such as CAN completes the configuration of the identity, and then the master node and the slave node can communicate using communication protocols such as CAN with a higher transmission rate, which solves the problem of poor timeliness caused by using LIN protocol communication, and greatly improves the communication timeliness of the master node and the slave node.

[0046] It should be noted that the master node pre-stores the installation positions of slave nodes corresponding to different preset identity identifiers. In this way, since the slave node is configured with an identity identifier based on a preset number corresponding to its installation position, after receiving the signal strength information sent by each slave node, the master node can determine the installation position of each slave node based on the identity identifier of the slave node and in combination with the pre-stored installation positions of the slave nodes corresponding to different preset identity identifiers, and then locate the vehicle key based on the signal strength information corresponding to different installation positions.

[0047] In one possible implementation, for the scenario of replacing a slave node after the vehicle is assembled off the assembly line, such as in the vehicle after-sales or maintenance scenario, in addition to the identity configuration of the slave node using the preset number written by the vehicle diagnostic device as mentioned above, the identity configuration can also be performed according to the following processing procedure: when the slave node detects that the communication network is connected, the slave node configures its own temporary identity in the communication network according to a preset method, and broadcasts an identity configuration request message in the communication network based on the temporary identity, so that the master node returns a configuration command carrying the identity of the slave node that has disappeared in the current communication network; the slave node configures the identity of the disappeared slave node as its own identity in the communication network.

[0048] In some embodiments, when a slave node detects that the communication network is connected, it indicates that the slave node is newly added to the communication network as a replacement node. At this time, the slave node can first configure its own temporary identity in the communication network in a preset manner, such as configuring a randomly generated identity as a temporary identity, or configuring a pre-stored identity as a temporary identity. Afterwards, the above-mentioned slave node can broadcast an identity configuration request message in the communication network according to the temporary identity to instruct the master node to return a configuration command carrying the identity of the slave node that has disappeared in the current communication network. Finally, the above-mentioned slave node can configure the identity of the received disappeared slave node as its own identity in the communication network. In this way, the newly added slave node will perform the car key positioning process normally according to the identity of the replaced slave node.

[0049] In order to facilitate understanding of the vehicle information configuration process provided by this application, the processing of the master node in the vehicle information configuration process is introduced below.

[0050] like Figure 3 As shown, a vehicle information configuration method is provided, which is applied to a slave node, and its specific processing includes:

[0051] Step 310: When the master node is powered on for the first time after being assembled, the master node records the communication identifiers of all slave nodes in the communication network.

[0052] In some embodiments, the master node may read and record the communication identifiers of all slave nodes in the communication network according to a preset communication protocol adopted by the communication network, such as the CAN communication protocol.

[0053] Step 320: When the master node receives the identification configuration request message in the communication network, the master node determines the identity of the slave node that has disappeared in the current communication network based on the recorded communication identifications of all slave nodes in the communication network.

[0054] In some embodiments, after receiving an identification configuration request message in the communication network, the master node can obtain the communication identification of all slave nodes in the current communication network, and then compare the communication identification of all slave nodes obtained with the communication identification of all slave nodes previously recorded. The non-overlapping identity identification obtained by the comparison is the identity identification of the slave node to be replaced, that is, the identity identification of the slave node that has disappeared.

[0055] Step 330: The master node returns a configuration command carrying the identity of the disappeared slave node, so that the slave node that sent the identity configuration request message configures the identity of the disappeared slave node as its identity in the communication network.

[0056] In some embodiments, the slave node that sends the identification configuration request message is a slave node that has newly joined the communication network. In this way, after the master node sends a configuration command carrying the identity of the disappeared slave node to the newly joined slave node, the newly joined slave node can configure the identity of the disappeared slave node as its identity in the communication network, so that the car key positioning process can be performed normally according to the identity of the replaced slave node.

[0057] In the embodiment of the present application, a method for configuring the identity of a slave node in a communication network of a non-LIN protocol such as CAN is provided, which enables the master node and the slave node to communicate using a communication protocol with a higher transmission rate such as CAN, solves the problem of poor timeliness caused by the communication using the LIN protocol, and greatly improves the communication timeliness of the master node and the slave node. In addition, due to the use of non-LIN communication protocols such as CAN, the hard wires arranged between the slave nodes in the LIN protocol are omitted, reducing the implementation cost of the keyless entry function.

[0058] In order to facilitate understanding of the processing of the above vehicle information configuration, a production line assembly method applying the vehicle information configuration method is given below.

[0059] First, each slave node has a default NFC key. After the production line has assembled the master and slave nodes and other components, the production line workers and other operators carry diagnostic instruments with NFC functions and approach the slave nodes on the vehicle in a clockwise order to make NFC connections. When the diagnostic instrument reads the NFC information of the slave node, the slave node is manually numbered, and then the number is written into the slave node through the diagnostic instrument. The specific process is as follows:

[0060] step1. The operator clicks the slave node configuration option on the diagnostic instrument, and a prompt box pops up on the diagnostic instrument, such as "Please scan the vehicle frame number and move the device clockwise toward the vehicle slave node";

[0061] Step 2. The operator brings the diagnostic instrument close to the vehicle slave node. After the diagnostic instrument recognizes the slave node, it reads the NFC device information according to the standard NFC protocol. After that, the slave node encrypts the stored vehicle information and device number with the existing NFC key and passes it to the diagnostic instrument;

[0062] Step 3. After receiving the information from the slave node, the diagnostic instrument decrypts the information and obtains the vehicle information transmitted from the slave node, and then compares it with the frame number scanned by itself to authenticate the slave node. If they are consistent, the diagnostic instrument pops up a prompt box to prompt the operator to number the current slave node;

[0063] Step 4. After the operator numbers the current slave node, click the write command of the diagnostic instrument, and the diagnostic instrument will pass the number, the device number and the frame number to the current slave node. It is worth mentioning that in order to facilitate assembly, the numbering can be carried out according to fixed rules, such as the slave node installed on the main driver's door is No. 1, and the slave node installed on the co-driver's door is No. 2;

[0064] step5. After the current slave node receives the information, it determines that the frame number and device number are consistent with its own, then it records the current number and changes its own identity according to the number; if they are inconsistent, it feeds back the error to the diagnostic instrument. After receiving the information, the diagnostic instrument prompts the error and exits the process.

[0065] Step 6. Repeat the above steps 2 to 5 for the remaining slave nodes to complete the identity configuration of all slave nodes. After all slave nodes are configured, the operator places the diagnostic instrument at each slave node in turn and establishes a Bluetooth connection between the diagnostic instrument and the master node. After that, the master node uses the signal strength sent by each slave node to confirm whether each slave node is configured correctly. For example, if the diagnostic instrument is placed at slave node No. 1, the signal sent by slave node No. 1 is the strongest.

[0066] Step 7. After the configuration is completed, each slave node sends a signal according to the configured identity. In addition, each slave node can also configure a specific identity in the signal to indicate that its identity has been configured.

[0067] 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.
