[0001] The present application relates to the technical field of data transmission, and in particular to a diagnostic interface data transmission control method, device, equipment, medium and vehicle. Background Art

[0002] In the traditional automotive field, the vehicle is usually inspected by connecting an external diagnostic instrument through a reserved vehicle diagnostic interface, so that developers can obtain vehicle configuration information, fault information, etc., and can also enable developers and after-sales personnel to upgrade vehicle software. Therefore, the reserved diagnostic interface has always been a design solution that many automobile manufacturers have consistently retained.

[0003] With the rapid development of automobile software technology in recent years, a new automobile software upgrade technology (i.e. OTA (Over-the-Air Download Technology)) has emerged. OTA upgrade not only brings a more convenient way to update automobile software, but also allows consumers to experience a more intelligent and convenient car experience. Therefore, OTA technology has become a better choice for more automobile manufacturers. However, as shown in the upgrade method of patent CN113325831A-A platform-based gateway routing method for automobile flashing diagnosis and patent CN113325831A-A platform-based gateway routing method for automobile flashing diagnosis, the final implementation method of OTA is still CAN (control area network) flashing, and the data transmission of the diagnostic equipment is also realized through CAN. Therefore, when OTA activities and diagnostic equipment exist on the bus at the same time, conflicts will inevitably occur, resulting in a large number of error frames, causing the diagnostic instrument to report errors, and the failure of operations such as electrical inspection and information acquisition performed at the same time, and other serious consequences. Summary of the invention

[0008] In one embodiment of the present invention, determining the data transmission status of the diagnostic interface according to the diagnostic request reception status includes: when the diagnostic instrument request status is a no-request status, controlling the vehicle's diagnostic interface to stop data transmission; when the diagnostic instrument request status is a requested status, controlling the vehicle's diagnostic interface to perform data transmission based on a diagnostic request message, and the diagnostic request message is issued based on the vehicle's diagnostic interface.

[0009] In one embodiment of the present invention, controlling the vehicle diagnostic interface to perform data transmission based on a diagnostic request message includes: determining a data type of the diagnostic request message, the data type including a control domain network type and a control domain network flexible data rate type; when the communication type is a control domain network type, controlling the vehicle's diagnostic interface to transmit data of the control domain network type; when the communication type is a control domain network flexible data rate type, controlling the vehicle's diagnostic interface to transmit data of the control domain network flexible data rate type.

[0010] In one embodiment of the present invention, if the remote upgrade status is upgrading, controlling the diagnostic interface of the vehicle to stop data transmission includes: issuing a prompt message that the remote upgrade status is upgrading, and controlling the diagnostic interface to disconnect from the diagnostic instrument.

[0011] The present invention provides a diagnostic interface data transmission control device, the device comprising: an information acquisition module, used for acquiring a remote upgrade status and a diagnostic request reception status of a vehicle; a first execution module, used for controlling the diagnostic interface of the vehicle to stop data transmission if the remote upgrade status is upgrading; and a second execution module, used for determining the data transmission status of the diagnostic interface according to the diagnostic request reception status if the remote upgrade status is not upgrading.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] First of all, it should be noted that there are many ways to implement the upgrade of OTA (Over-the-Air Download Technology). In this invention, the implementation method of CAN (Control Area Network) is mainly discussed. Therefore, the implementation process of OTA can be simply divided into three steps: first, the automobile manufacturer pushes the software to be updated; second, the car is connected to the Internet for downloading; third, the corresponding ECU is upgraded via the CAN bus inside the car. Since the final implementation method of OTA is still CAN flashing, and it is generally in CANFD format, but in actual situations, diagnostic equipment often only supports CAN format. Therefore, when OTA activities and diagnostic equipment exist on the bus at the same time, conflicts will inevitably occur, and a large number of error frames will be generated, causing the diagnostic instrument to report errors, and the electrical inspection, information acquisition and other operations performed at the same time will fail.

[0028] Figure 1 FIG. 1 is a schematic diagram showing an implementation environment of a diagnostic interface data transmission control according to an exemplary embodiment of the present application. Figure 1 As shown, the system architecture may include a current vehicle 101 and a computer device 102. The computer device 102 may be at least one of a desktop graphics processing unit (GPU) computer, a GPU computing cluster, a neural network computer, etc. Relevant technicians may use the computer device 102 to obtain the current upgrade task status and diagnostic request status of the vehicle, thereby determining whether to respond to the diagnostic request based on the upgrade task status, and when responding to the diagnostic request, transmitting data to the diagnostic interface based on the message format of the diagnostic request.

[0029] Figure 2 is a schematic diagram of a diagnostic interface data transmission control method shown in an exemplary embodiment of the present application. The method can be applied to Figure 1 The implementation environment shown is specifically executed by the smart terminal 102 in the implementation environment. It should be understood that the method can also be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment to which the method is applicable.

[0030] like Figure 2 As shown, in an exemplary embodiment, the diagnostic interface data transmission control method includes at least steps S210 to S230, which are described in detail as follows:

[0031] Step S210, obtaining the remote upgrade status and diagnosis request reception status of the vehicle.

[0032] It should be understood that the vehicle obtains task data through OTA download to determine its remote upgrade status, so obtaining the remote upgrade status of the vehicle includes: obtaining the task data of the vehicle remote upgrade task, the task data includes the task type and task parameters; if the task type includes the remote upgrade type, the current upgrade status is determined based on the task parameters, and the current upgrade status includes upgrading and not upgraded.

[0033] In one embodiment of the present invention, the current task data of the vehicle is obtained through OTA download. After detection, if the task data does not include the remote upgrade type, it is determined that the current remote upgrade status of the vehicle is not upgraded.

[0034] Figure 3 is a flowchart of a diagnostic interface data transmission control method shown in an exemplary embodiment of the present application, such as Figure 3 As shown, firstly, the OTA upgrade task is artificially determined as the first priority task, and the diagnostic instrument request task is determined as the second priority task, so as to achieve CAN isolation. During the data transmission process, when the vehicle is in the OTA upgrade state, it is forbidden to send messages to the diagnostic interface; when the vehicle is in the OTA non-upgrade state, a message is sent to the diagnostic interface based on the diagnostic request (i.e., the diagnostic instrument request) issued by the diagnostic instrument; if the message type of the diagnostic request is CANFD, a CANFD message is sent to the diagnostic interface, if the message type of the diagnostic request is CAN, a CAN message is sent to the diagnostic interface, and if the diagnostic request is empty, it is forbidden to send messages to the diagnostic interface.

[0035] Step S220: If the remote upgrade status is in progress, control the vehicle's diagnostic interface to stop data transmission.

[0036] It should be understood that when the remote upgrade status of the vehicle is upgrading, controlling the diagnostic interface of the vehicle to stop data transmission includes: sending a prompt message that the remote upgrade status is upgrading, and controlling the diagnostic interface to disconnect from the diagnostic instrument.

[0037] In one embodiment of the present invention, if it is determined based on the task data of the remote upgrade of the vehicle that the current remote upgrade status of the vehicle is upgrading, sending messages to the diagnostic interface is prohibited, and at the same time, the user is informed that "the current vehicle is in remote upgrade status" through methods including but not limited to text reminders on the display screen or broadcast voice reminders, and the diagnostic interface is controlled to disconnect from the diagnostic device, thereby stopping the transmission of data to the diagnostic interface.

[0038] Step S230 : if the remote upgrade status is not upgraded, determine the data transmission status of the diagnostic interface according to the diagnosis request reception status.

[0039] It should be understood that when the diagnostic request status is different, the status of data transmission to the diagnostic interface is also different. Therefore, before determining the data transmission status of the diagnostic interface according to the diagnostic request reception status, it also includes: determining the diagnostic request status as requested or not requested based on the diagnostic request reception status; when the reception status of the diagnostic request message is received, determining the diagnostic instrument request status as requested; when the reception status of the diagnostic request message is not received, determining the diagnostic instrument request status as not requested.

[0040] Determining the data transmission status of the diagnostic interface according to the diagnostic request reception status includes: when the diagnostic instrument request status is a no-request status, controlling the vehicle's diagnostic interface to stop data transmission; when the diagnostic instrument request status is a requested status, controlling the vehicle's diagnostic interface to perform data transmission based on the diagnostic request message, and the diagnostic request message is issued based on the vehicle's diagnostic interface.

[0041] In one embodiment of the present invention, if the OTA upgrade status is determined to be not upgraded through detection, the diagnostic request status, that is, the receiving status of the diagnostic request message, is further determined. If the receiving status of the hydrogen message is detected to be not received, it is determined that the diagnostic interface has no diagnostic request, so the message is stopped from being sent to the diagnostic interface.

[0042] In another embodiment of the present invention, if the OTA upgrade status is determined to be not upgraded through detection, the diagnostic request status, that is, the receiving status of the diagnostic request message, is further determined. If the receiving status of the hydrogen message is detected to be received, it is determined that the diagnostic interface has a diagnostic request, and a message needs to be sent to the diagnostic interface according to the content of the diagnostic request to complete the data transmission.

[0043] It should be understood that since the diagnostic messages sent by the diagnostic interface include multiple data types, controlling the vehicle diagnostic interface to perform data transmission based on the diagnostic request message includes: determining the data type of the diagnostic request message, the data type includes the control domain network type and the control domain network flexible data rate type; when the communication type is the control domain network type, then controlling the vehicle diagnostic interface to transmit data of the control domain network type; when the communication type is the control domain network flexible data rate type, then controlling the vehicle diagnostic interface to transmit data of the control domain network flexible data rate type.

[0044] In one embodiment of the present invention, if the OTA upgrade status is determined to be not upgraded through detection, the diagnostic request status, that is, the receiving status of the diagnostic request message, is further determined. If the receiving status of the diagnostic request message is detected to be received, it is determined that the diagnostic interface has a request, so based on the diagnostic request, the diagnostic request message is obtained, and the data type of the diagnostic request message is determined. If the data type of the diagnostic request message is CAN, CAN data is transmitted to the diagnostic interface to realize data transmission of the diagnostic interface.

[0045] In one embodiment of the present invention, when the vehicle OTA upgrade status is not upgraded and the diagnostic request status is requested, it is determined through detection that the data type of the diagnostic request message is CANFD, then data of the CANFDA data type is transmitted to the diagnostic interface to realize diagnostic interface data transmission.

[0046] Figure 4 It is a flowchart of a diagnostic interface data transmission control method shown in another exemplary embodiment of the present application; as shown in Figure 4, in the process of transmitting data to the diagnostic interface, the first thing that needs to be judged is the OTA upgrade status. When the OTA upgrade status is upgrading, the vehicle's diagnostic interface is controlled to stop data transmission (i.e., routing messages to the diagnostic interface is prohibited). When the OTA upgrade status is not upgrading (i.e., the OTA status is not upgraded), the status of the diagnostic request is further determined by determining the receiving status of the diagnostic request to determine whether it is requested or not. If the receiving status of the diagnostic request is not received, the status of the diagnostic request is determined to be no request, and routing messages to the diagnostic interface is prohibited; if the receiving status of the diagnostic request is received, the status of the diagnostic request is determined to be requested, and the diagnostic request data type is determined based on the received diagnostic request message. If the diagnostic request data type is CAN, CAM type data is sent to the diagnostic interface. If the diagnostic request data type is CANFD, CANFD type data is sent to the diagnostic interface.

[0047] like Figure 5 As shown, the exemplary diagnostic interface data transmission control device includes: an information acquisition module 510 , a first execution module 520 , and a second execution module 530 .

[0048] Among them, the information acquisition module 510 is used to obtain the remote upgrade status and diagnostic request reception status of the vehicle; the first execution module 520 is used to control the vehicle's diagnostic interface to stop data transmission if the remote upgrade status is upgrading; the second execution module 530 is used to determine the data transmission status of the diagnostic interface according to the diagnostic request reception status if the remote upgrade status is not upgraded.

[0049] It should be noted that the diagnostic interface data transmission control device provided in the above embodiment and the diagnostic interface data transmission control method provided in the above embodiment belong to the same concept, wherein the specific manner in which each module and unit performs the operation has been described in detail in the method embodiment, and will not be repeated here.

[0050] An embodiment of the present application also provides an intelligent vehicle, which is equipped with the above diagnostic interface data transmission control device.

[0051] In one embodiment of the present invention, before transmitting data to the diagnostic interface, the intelligent vehicle first determines its OTA upgrade status, and then determines the diagnostic request status of the diagnostic interface. When the OTA upgrade status is not upgraded and the diagnostic request status of the diagnostic interface is requested, based on the data type of the diagnostic request message sent by the diagnostic interface, a message of the corresponding data type is synchronized to the diagnostic interface to complete the data transmission. When the data type of the diagnostic request message sent by the diagnostic interface is CAN, the CAN message is synchronized to the diagnostic interface to complete the data transmission to the diagnostic interface; when the data type of the diagnostic request sent by the diagnostic interface is CANFD, the CANFD message is synchronized to the diagnostic interface to complete the data transmission to the diagnostic interface.
