[0002] With the development of science and technology, vehicle remote upgrade (OTA) technology has gradually become popular in automobiles. OTA technology is no longer exclusive to certain vehicles. Fuel vehicles and electric vehicles are equipped with OTA functions one after another, and the upgrade scope is no longer limited to experience-related functions, but is oriented to the entire domain. Among them, the controllers upgraded by the vehicle include those upgraded through LIN and other low-speed channels, such as sensors.

[0003] However, the characteristics of LIN determine that the LIN node in the car is composed of a master node and multiple slave nodes. The master node is usually a controller that uses CAN / CANFD / Ethernet communication, and the slave node is a controller that uses LIN communication. The controller diagnosis of LIN communication is controlled by the master node. Similarly, the flashing of LIN line communication controller is directly controlled by the master node. Therefore, the timeliness of the controller using LIN line communication is usually much lower than that of the controller using CAN line communication. Summary of the invention

[0023] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0025] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0026] First of all, it should be explained that OTA, which stands for Over-the-Air Technology (OTA), is a technology that remotely manages mobile terminal devices and SIM card data through the air interface of mobile communications. Its OAT flashes the local maintenance of the host computer, which involves the master node attribute table, which includes the master node diagnostic identification (Identification, referred to as ID), and the diagnostic ID of the managed slave node (the network where the master node is located is the CAN / CANFD network), and the number of repetitions of the current flash instruction when the flash fails. The local maintenance of the master node involves the slave node attribute table, which involves the slave node address NAD (node ​​addres, referred to as NAD) corresponding to the slave node diagnostic ID / logical address, and the LIN network to which the slave node belongs. When the master node receives the flash message from the OTA host computer, it identifies the specific slave node that needs to be flashed according to the mapping relationship in the slave node attribute table.

[0027] Figure 1 It is a schematic diagram of an implementation environment for upgrading a vehicle controller during navigation, shown as an exemplary embodiment of the present application.

[0028] like Figure 1 As shown, it includes an OTA host computer 101 and a controller 102 that needs to be upgraded. Among them, the OTA host computer 101 and the controller 102 that needs to be upgraded are integrated in the vehicle side and connected through a local interconnect network (Local Interconnect Network, referred to as LIN network), which includes a master node and a slave node. Each master node includes multiple slave nodes. The slave nodes belonging to the same master node have a unique LIN network, and the same LIN network includes different master nodes. The OTA host computer sends update data to the slave node through the master node, thereby flashing the controller that needs to be upgraded to achieve the upgrade of the vehicle-side controller.

[0029] like Figure 2 As shown, in an exemplary embodiment, the vehicle controller upgrade method includes at least steps S210 to S240, which are described in detail as follows:

[0030] Step S210, obtaining the task to be upgraded, which includes the target slave node information and the flashing data for upgrading the vehicle controller.

[0031] The OTA host computer obtains the corresponding upgrade task according to the upgrade needs of the vehicle, and the upgrade task includes but is not limited to the flash data for upgrading the slave node information and the vehicle controller.

[0032] Step S220, determining the upgrade slave node of the task to be upgraded according to the target slave node information, the upgrade slave nodes belonging to at least two upgrade master nodes.

[0033] Before determining the upgrade slave node of the task to be upgraded according to the target slave node information, it also includes: obtaining the master node configuration information, including the slave node, the slave node diagnostic identifier and the slave node logical address; based on the slave node, the slave node diagnostic identifier and the slave node logical address, determining the mapping relationship between the slave node and the slave node diagnostic identifier, and the mapping relationship between the slave node and the slave node logical address to generate a master node configuration information table.

[0034] The information of multiple master nodes and the slave node information corresponding to the master node are obtained, including the network type to which the master node belongs, the master node identification information, the slave node diagnostic ID, the slave node LIN network, the slave node logical address and the number of retries, and a master node configuration information table is formed based on the above information, as shown in Table 1:

[0035] Table 1

[0036]

[0037] Among them, the network type to which the LIN control master node belongs is mainly to identify the network segment through which the OTA host computer communicates with the master node, such as whether the OTA host computer and the master node communicate through the power CAN network segment or through Ethernet. When the network type of the master node is the CAN data type, the identification information of the master node is the master node diagnostic identification (Identification, referred to as ID); when the data type of the master node is Ethernet data, the identification information of the master node is the protocol for interconnection between the master node networks (Internet Protocol, referred to as IP). And each master node includes multiple slave nodes with different LIN networks, and the LIN network information of the slave node can indicate its specific slave node identity. In addition, the master node configuration information table also includes the number of retries for each slave node. When the slave node fails to refresh, the OTA host computer will retry the failed slave node according to the number of retries until it succeeds or its number of retries reaches the preset number.

[0038] Determining the upgrade slave node of the task to be upgraded according to the target slave node information includes: obtaining the target slave node identification information of the target slave node, the target slave node identification information includes the target slave node diagnostic identification and the target slave node logical address; based on the target slave node diagnostic identification, matching the master node configuration information table to obtain the upgrade slave node, or based on the target slave node logical address, matching the master node configuration information table to obtain the upgrade slave node.

[0039] The identification information of the slave node includes the slave node diagnostic ID and the slave node logical address. After the slave node diagnostic ID or the slave node logical address is determined, the corresponding slave node can be obtained in the master node configuration information table.

[0040] In one embodiment of the present invention, based on the identification information of the slave node, it is determined that the slave node diagnostic ID of the slave node is SNA2, then SNA2 is searched in the master node configuration information table, and its corresponding slave node information is found to be slave node 2.

[0041] In one embodiment of the present invention, based on the identification information of the slave node, it is determined that the slave node logical address of the slave node is LA2, then LA2 is searched in the master node configuration information table, and its corresponding slave node information is found to be slave node 11.

[0042] Step S230: sending the flash data to the upgrade slave node to trigger the upgrade slave node to generate a response message.

[0043] Sending the flash data to the upgraded slave node to trigger the upgraded slave node to generate a response message includes: obtaining the master node configuration information table, the master node configuration information table includes the network type to which the master node belongs and the mapping relationship between the slave node and the master node; determining the data type of the master node based on the master node configuration information table and the upgraded slave node; when the master node data type is dynamic data, encapsulating the command message into a bus diagnostic message, and sending it to the host computer based on the node address, or when the master node data type is Internet Protocol data, encapsulating the command message into an Ethernet data frame, and sending it to the host computer based on the node address.

[0044] In one embodiment of the present invention, the network type to which the master node belongs is first determined according to the master node configuration information table. When the data type of the master node is dynamic data, the configuration information of the slave nodes related to the master node is obtained, including the slave node LIN network, diagnostic ID, and NAD, to generate a configuration information table of the related slave nodes, as shown in Table 2:

[0045] Table 2

[0046] LIN network Diagnostic ID NAD From Node 1 LIN1 SNA1 NAD1 Slave Node 2 LIN1 SNA2 NAD2 Slave Node 3 LIN2 SNA3 NAD3 Slave Node 4 LIN2 SNA4 NAD4 Slave Node 5 LIN3 SNA5 NAD5 Slave Node 6 LIN3 SNA6 NAD6

[0047] The LIN network information is used to determine the specific LIN network to which the slave node belongs, such as LIN1, LIN2, etc. The diagnostic ID is used by the master node to identify the specific slave node information that needs to be upgraded based on the diagnostic ID sent by the received OTA; NAD is used to distinguish the limbs of different slave nodes, and flashing is the slave node identifying whether it needs to process the message based on the NAD.

[0048] In one embodiment of the present invention, the master node receives the diagnostic ID sent by the OTA host computer, identifies that the diagnostic ID is SNA1, and determines that the slave node corresponding to the instruction is slave node 1, whose NAD is NADA1. The master node then encapsulates the instruction message into a CAN / CANFD message and sends it to the host computer based on the node address NAD1, thereby triggering the host computer to perform a flashing action.

[0049] In one embodiment of the present invention, the network type to which the master node belongs is first determined according to the master node configuration information table. When the data type of the master node is Internet protocol data, the configuration information of the slave nodes related to the master node is obtained, including the slave node LIN network, logical address, and NAD, to generate a configuration information table of the related slave nodes, as shown in Table 3:

[0050] Table 3

[0051]

[0052]

[0053] The LIN network information is used to determine the specific LIN network to which the slave node belongs, such as LIN1, LIN2, etc. The logical address is used by the master node to identify the specific slave node information that needs to be upgraded based on the diagnostic ID sent by the received OTA; NAD is used to distinguish the addresses of different slave nodes, and flashing is the slave node identifying whether it needs to process the message based on the NAD.

[0054] In one embodiment of the present invention, the master node receives the diagnostic ID sent by the OTA host computer, identifies the logical address as LA1, and determines that the slave node corresponding to the instruction is slave node 1, whose NAD is NADA1. The master node then encapsulates the instruction message into an Ethernet data frame and sends it to the host computer based on the node address NAD1, thereby triggering the host computer to perform a flashing action.

[0055] Step S240, if the host computer obtains the response message, based on the local area interconnection network information of each upgrade slave node, the host computer executes the flashing action on the upgrade slave nodes with the same local area interconnection network information in parallel to upgrade the vehicle controller.

[0056] Before the upper computer executes the flashing action in parallel on the upgraded slave nodes with the same local interconnection network information, it also includes: obtaining the configuration information of the slave nodes to generate a slave node configuration information table, the slave node configuration information includes the network to which the slave node belongs, the slave node diagnostic identifier, and the slave node logical address, the slave node configuration information table includes the mapping relationship between the slave node diagnostic identifier and the slave node local interconnection network, and the mapping relationship between the slave node logical address and the slave node local interconnection network; determining the upgraded slave node local interconnection network of the upgraded slave node based on the upgraded slave node and the slave node configuration information table; grouping the upgraded slave nodes based on the upgraded slave node local interconnection network; and executing the flashing action in parallel on the upgraded slave nodes in the same group.

[0057] In one embodiment of the present invention, according to the upgrade task, the slave nodes involved in the upgrade task include slave node 1, slave node 4, slave node 5, and slave node 7. Based on the master node configuration information table (Table 1), the LIN network corresponding to slave node 1 is LIN1, the LIN network corresponding to slave node 4 is LIN1, the LIN network corresponding to slave node 5 is LIN2, and the LIN network corresponding to slave node 7 is LIN1. Then, according to the LIN network, the above-mentioned slave node 1, slave node 4, and slave node 7 are divided into a group, and the flashing data is sent to them at the same time, and the flashing action is performed in parallel.

[0058] After the upper computer executes the flashing action in parallel on the upgraded slave nodes with the same local interconnection network information, it also includes: obtaining the execution result of the upper computer and feeding back the execution result to the slave node to generate a new feedback message; sending the feedback message to the upper computer to determine the upgrade status of the target vehicle controller.

[0059] A feedback message is sent to the host computer to determine the upgrade status of the target vehicle controller, including: determining the first flashing status based on the feedback message, when the first flashing status is a flashing success, determining that the target vehicle controller has been successfully upgraded; when the first flashing status is a flashing failure, obtaining the number of flashing times, if the number of flashing times is less than or equal to the preset standard number of times, repeating the flashing until the flashing is successful, determining that the target vehicle controller has been successfully upgraded, if the number of flashing times is greater than the preset standard number of times, ending the flashing process, and determining that the upgrade of the target vehicle controller has failed.

[0060] Figure 3 It is a flowchart of determining the upgrade status of a vehicle controller shown in an exemplary embodiment of the present application.

[0061] like Figure 3As shown, during the flashing process performed by the host computer, there are two situations: flashing success or flashing failure. When the first flashing is successful, the flashing process is directly terminated. When the flashing fails, the flashing needs to be repeated. In the process of repeated flashing, the number of flashing is first obtained, and the maximum number of flashing is preset to N. When the number of flashing is less than N, the flashing continues. If the flashing is successful, the flashing process is terminated. If the flashing fails, the flashing is repeated; until the number of flashing is greater than or equal to N, the flashing process is directly terminated, and it is determined that the upgrade task corresponding to the flashing process has failed.

[0062] In one embodiment of the present invention, the host computer flashes the target vehicle controller according to a certain upgrade task, and the first flash is successful, so the flash process is ended and it is determined that the upgrade task is successfully upgraded.

[0063] In one embodiment of the present invention, taking the preset maximum number of flashing times N=10 as an example, the upper computer flashes the target vehicle controller according to a certain upgrade task, and then repeats the flashing, and obtains the number of flashing times in the process. When the flashing is successful for the ninth time, the flashing process is terminated and it is determined that the upgrade task is successfully upgraded.

[0064] In one embodiment of the present invention, taking the preset maximum number of flashing times N=10 as an example, the upper computer flashes the target vehicle controller according to a certain upgrade task, and then repeats the flashing, and obtains the number of flashing times in the process. When the ninth flashing occurs, the flashing fails. When the tenth flashing occurs, since the number of flashing times is equal to the preset maximum number of flashing times N, the flashing process is directly terminated, and it is determined that the upgrade task has failed.

The device can be applied to Figure 1 The device may also be applicable to other exemplary implementation environments and specifically configured in other devices, and this embodiment does not limit the implementation environment to which the device is applicable.
