[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that all actions of acquiring signals, information or data in the present invention are performed in compliance with the corresponding data protection laws and policies of the location and with the authorization given by the owner of the corresponding device.

[0027] Figure 1 FIG. 1 is one of the flow charts of the method for automatically identifying the heavy truck vehicle architecture provided by the present invention, such as Figure 1 As shown, the present invention provides a method for automatically identifying a heavy truck vehicle architecture, comprising steps S100 to S200.

[0028] Step S100, in response to the identification request of the host computer, based on the preset communication module and the preset test scheme, a test online instruction is sent to the test object of the heavy truck vehicle, wherein the test object includes the diagnostic bus DCAN and the power bus PCAN. The diagnostic bus DCAN and the power bus PCAN each include a controller, and each controller is connected via a CAN bus.

[0029] As there are more and more controllers on the car, setting up a CAN bus may lead to too high a load rate, and different controllers have different requirements for communication rates. Therefore, the CAN bus is usually divided into several categories according to different functional components on the actual vehicle, such as power CAN (PCAN), body CAN, chassis CAN, diagnostic CAN (DCAN), etc. Different CAN buses exchange information through gateways. A CAN network needs to specify a communication baud rate, and each node communicates data at the same baud rate. Since the characteristics of the diagnostic protocol are often based on the request-response mechanism, the diagnosis of the vehicle through the diagnostic CAN is the basic way for the terminal to realize the vehicle diagnostic function. Most of the terminal's diagnosis of the vehicle occurs on PCAN or DCAN. PCAN is responsible for vehicle power and is the CAN bus with the highest signal priority and signal transmission rate in the vehicle CAN network. The DCAN bus mainly provides remote diagnostic functions. Therefore, the present invention sets the test object as the diagnostic bus DCAN and the power bus PCAN to improve the test efficiency while ensuring the test results.

[0030] Step S200, determining the architecture of the heavy truck vehicle according to the test results corresponding to the test scheme, wherein the architecture of the heavy truck vehicle is used to characterize the existence, receiving address, supported baud rate and OBD interface configuration of the test object.

[0031] It can be understood that the present invention can send test online instructions to the test object of the heavy-duty truck vehicle according to a preset test plan based on the communication module, automatically detect and identify the existence, receiving address, supported baud rate and on-board diagnostic system OBD interface configuration of the diagnostic bus DCAN and power bus PCAN of the heavy-duty truck vehicle, and realize fast and accurate communication establishment, greatly reducing the risk of human operation errors.

[0032] Based on the above embodiment, as an optional embodiment, the communication module includes a first OBD interface and a second OBD interface. Correspondingly, sending a test online instruction to the test object of the heavy truck vehicle based on a preset communication module and a preset test scheme includes the following steps.

[0033] Step S110, setting the interface configuration IDs corresponding to the first OBD interface and the second OBD interface respectively, setting the first test baud rate corresponding to the diagnostic bus DCAN and the second test baud rate corresponding to the power bus PCAN.

[0034] Pins 6 and 14 of the CAN bus interface are set as the first OBD interface, and the interface configuration ID is 72; pins 11 and 12 of the CAN bus interface are set as the second OBD interface, and the interface configuration ID is 73.

[0035] The vehicle controllers of heavy trucks are interconnected through various bus technologies. Controllers with the same CAN bus type and baud rate can be used as a control unit. The present invention divides the vehicle controller into three control units. They are control unit A on DCAN, control unit B on PCAN, and control unit B. The first test baud rate is 500K, and the second test baud rate includes 500K corresponding to control unit B and 250K corresponding to control unit C.

[0036] Step S120: Generate a first test online instruction corresponding to the first OBD interface and a second test online instruction corresponding to the second OBD interface according to the interface configuration ID, a preset sending address and a preset receiving address.

[0037] Taking the address of control unit A as an example, the first test online command sent to DCAN or PCAN using the first OBD interface (pins 6 and 14) is as follows:

[0038] The second test online command sent to DCAN or PCAN using the second OBD interface (pins 11 and 12) is as follows:

[0039] Step S130, obtaining at least one test scheme according to the first test baud rate, the second test baud rate, the first test online instruction and the second test online instruction, wherein the test scheme is used to characterize that the first OBD interface sends the first test online instruction according to the first test baud rate or the second test baud rate, or that the second OBD interface sends the second test online instruction according to the first test baud rate or the second test baud rate.

[0040] Step S140: sending a test online instruction to the test object of the heavy truck according to the test plan.

[0041] Figure 2 FIG. 2 is a flow chart of the automatic identification method for heavy truck vehicle architecture provided by the present invention. Figure 2 As shown, based on the above embodiment, as an optional embodiment, determining the architecture of the heavy truck vehicle according to the test results corresponding to the test scheme includes the following steps.

[0042] Step S210, if the test result corresponding to the first test online instruction sent by the first OBD interface (i.e., port A in the figure, the same below) at the first test baud rate is successful, it is determined that the existence of the diagnostic bus DCAN is online, the receiving address is the receiving address corresponding to the first test online instruction, the supported baud rate is the first test baud rate, and the OBD interface is configured as the first OBD interface.

[0043] Step S220, if the test result corresponding to the first test online instruction sent by the first OBD interface at the first test baud rate is successful, then based on the second OBD interface (i.e., port B in the figure, the same below), the second test online instruction is sent at the second test baud rate. If the test result is successful, it is determined that the existence of the power bus PCAN is online, the receiving address is the receiving address corresponding to the second test online instruction, the supported baud rate is the second test baud rate, and the OBD interface is configured as the second OBD interface.

[0044] Step S230, if the test result corresponding to the first test online instruction sent by the first OBD interface at the first test baud rate is failure, then based on the second OBD interface, the second test online instruction is sent at the first test baud rate. If the test result is success, it is determined that the existence of the diagnostic bus DCAN is online, the receiving address is the receiving address corresponding to the second test online instruction, the supported baud rate is the second test baud rate, and the OBD interface is configured as the second OBD interface.

[0045] Step S240, if the test result corresponding to the second test online instruction sent by the second OBD interface at the first test baud rate is successful, then based on the first OBD interface, the first test online instruction is sent at the second test baud rate. If the test result is successful, it is determined that the existence of the power bus PCAN is online, the receiving address is the receiving address corresponding to the first test online instruction, the supported baud rate is the second test baud rate, and the OBD interface is configured as the first OBD interface.

[0046] Step S250: The existence, receiving address, supported baud rate and OBD interface configuration of the diagnostic bus DCAN and the power bus PCAN are used as the architecture of the heavy truck vehicle.

[0047] Specifically, the present invention first detects whether the control unit A of the first OBD interface is online, and if it is online, the baud rate of DCAN is fed back as 500K. After the test is successful, the control unit B of the second OBD interface is detected, and if it is online, the baud rate of PCAN is fed back as 500K, and if it is unsuccessful, the baud rate of PCAN is fed back as 250K.

[0048] If the control unit A of the first OBD interface is not online, the second OBD interface is detected to see if the control unit A exists. If the control unit A of the second OBD interface is online, the baud rate of DCAN is reported as 500K. After the test is successful, the control unit B of the first OBD interface is detected to see if it is online. If it is online, the baud rate of PCAN is reported as 500K. If it is unsuccessful, the baud rate of PCAN is reported as 250K.

[0049] It is understandable that the type of electronic control unit is classified according to the type of CAN bus where the control unit is located (on DCAN or PCAN) and the baud rate of the control unit. Controllers with the same CAN bus type and baud rate can be used as a control unit, and a control unit can include multiple on-board controllers. The present invention determines whether the electronic control unit is online by sending a test instruction, and then determines the existence, supported baud rate and OBD interface configuration of the diagnostic bus DCAN and the power bus PCAN respectively according to the feedback. Therefore, the present invention can quickly and accurately determine whether the entire vehicle architecture and the electronic control unit are online.

[0050] On the basis of the above embodiment, as an optional embodiment, the method for automatic identification of heavy truck vehicle architecture provided by the present invention further includes the following steps.

[0051] Step S300: If the diagnostic bus DCAN and / or the power bus PCAN are online, a diagnostic operation specified by the host computer is performed on the diagnostic bus DCAN and / or the power bus PCAN.

[0052] Step S400: If the diagnostic bus DCAN and / or the power bus PCAN are / is not online, an error message is fed back.

[0053] When a diagnostic request is received from the host computer software, the diagnosed object information specified in the request is parsed, and first, according to the automatic test steps provided in step S100 and step S200, it is determined in real time whether the target control unit is online. If the target control unit is online, it automatically enters the next diagnostic operation, including but not limited to reading fault codes, clearing fault codes, program upgrades, actuator testing, etc. If the target control unit is not online, error information is immediately fed back to the user, including but not limited to control unit failure, communication failure, etc., and necessary troubleshooting suggestions are provided. Optionally, if automatic detection cannot be completed, the corresponding architecture can be manually selected according to the vehicle architecture status.

[0054] It can be understood that the present invention can quickly identify the vehicle network architecture and enable operators to quickly locate and solve problems, thereby reducing maintenance time and improving work efficiency.

[0055] Based on the above embodiment, as an optional embodiment, the communication module includes serial communication, USB interface, Ethernet interface, Bluetooth module and WiFi module.

[0056] Specifically, the present invention integrates a variety of hardware interface protocols, including serial communication (such as RS-232, RS-485), USB interface, Ethernet interface, and wireless communication technologies such as Bluetooth and Wi-Fi, covering various communication standards used by the first to third generation diagnostic tools of existing heavy trucks, ensuring seamless connection between software and hardware. Among them, the first generation diagnostic tool (white box) is limited to the use of 32-bit Windows system environment, and exchanges data with the system through the USB interface; the second generation diagnostic tool (black box) supports both 32-bit and 64-bit Windows system environments, and also uses a USB interface for connection; the third generation diagnostic tool (gray box) supports use in 32-bit Windows system and 64-bit Windows system environment, and is further expanded to multiple connection methods such as wired (such as USB, Ethernet, etc.) and wireless (such as WIFI, Bluetooth), to meet the flexible needs in different application scenarios.

[0057] It can be understood that the present invention is compatible with different diagnostic tools, adapts to the flexible needs in different application scenarios, realizes cross-generational compatibility and collaborative work, and facilitates the development of vehicle diagnostic software. Developers can focus more on the realization of diagnostic functions without having to worry about communication compatibility issues between different models.
