Description

Technical Field

[0001] This invention relates to the field of vehicle information detection, and in particular to a method, device and medium for detecting vehicle ECUs based on ECALL. Background Technology

[0002] Current methods for detecting information from in-vehicle ECUs (Electronic Control Units) are based on T-BOX (Telematics Box, an important component of vehicle networking systems; the in-vehicle T-BOX communicates with the gateway and vehicle network via a CAN transceiver to collect data from other ECUs, and communicates with the vehicle manufacturer's service provider's backend system via the network to report data). Based on the in-vehicle T-BOX, it can connect to the vehicle manufacturer's service provider's backend and can also be accessed via UDS (Unified Diagnostic System). Unified Diagnostic Services (UDS) is a standardized on-board diagnostic protocol used to enable communication between diagnostic equipment (such as diagnostic tools and on-board systems) and on-board ECUs to perform diagnostic functions such as fault detection, parameter reading, and program flashing. The diagnostic protocol communicates with other ECUs in the vehicle network. Automakers typically pre-embed the UDS diagnostic configuration corresponding to the vehicle ECU information they need into the T-BOX. After the automaker initiates a diagnostic request through the automaker's service provider backend, the T-BOX executes the corresponding diagnostic instructions according to the pre-embedded configuration items and reports the obtained ECU information to the automaker's service provider backend, enabling the automaker to promptly understand the vehicle's status and whether there are any faults.

[0003] Therefore, the existing method for detecting and obtaining vehicle ECU information is to use an on-board T-BOX to read the ECU information remotely or through self-diagnosis and report it to the vehicle manufacturer's service provider's backend. However, this method cannot achieve the purpose of remotely reading ECU information for vehicles that have not installed a T-BOX. Summary of the Invention

[0011] The service information corresponding to the diagnostic information sent by the vehicle's onboard emergency call system is sent to the vehicle information service provider platform via the network communication service provider platform.

[0017] Based on the vehicle identification code included in the detection information, the detection information is sent to the vehicle emergency call system of the target vehicle corresponding to the vehicle identification code by calling the SMS delivery interface.

[0018] In one exemplary embodiment of this application, the network communication service providing platform is further configured to perform the following steps:

[0019] In response to receiving service information from the target vehicle's onboard emergency call system, the service information is sent to the onboard information service provider platform.

[0020] In one exemplary embodiment of this application, the onboard emergency call system of the target vehicle is used to perform the following steps:

[0021] In response to receiving detection information sent by the network communication service provider platform, the detection information is parsed to obtain the diagnostic content included in the detection information;

[0022] Based on the diagnostic results, a corresponding diagnostic instruction message is generated and sent to the vehicle control module of the target vehicle.

[0023] In one exemplary embodiment of this application, the onboard emergency call system of the target vehicle is further configured to perform the following steps:

[0027] In response to receiving a diagnostic command message sent by the onboard emergency call system of the target vehicle, the diagnostic information of the target vehicle corresponding to the diagnostic command message is obtained according to the diagnostic command message.

[0028] The diagnostic information is sent to the target vehicle's onboard emergency call system.

[0029] In one exemplary embodiment of this application, the on-board emergency call system of the target vehicle integrates the diagnostic service function of the automotive electronic diagnostic communication standard protocol;

[0030] The diagnostic command message is a message generated according to the automotive electronic diagnostic communication standard protocol.

The target vehicle's vehicle emergency call system, upon receiving the diagnostic information, compiles it into service information and sends it to the vehicle information service provider via the network communication service provider. This allows for remote acquisition of vehicle ECU information in vehicles without a T-BOX, without requiring pre-installed diagnostic configuration items. Attached Figure Description

[0037] Figure 2 This is a schematic diagram of the information transmission link of the information detection system provided in an embodiment of the present invention. Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This application proposes an ECALL-based method for detecting vehicle-mounted ECUs, applied to an information detection system. The information detection system includes an in-vehicle information service provider platform (such as...). Figure 2 The vehicle manufacturer's TSP platform shown is a Telematics Service Provider platform, and the network communication service provider platform (such as...) Figure 2The telecommunications operators shown are network service providers, and vehicle emergency call systems (such as...) Figure 2 The ECALL system (Emergency Call system) and vehicle control module shown are shown in the diagram. Figure 2 The vehicle-mounted ECU shown in the figure integrates diagnostic service functions of the Automotive Electronic Diagnostic Communication Standard Protocol (UDS Protocol) to support the sending of UDS Protocol messages.

[0040] Among them, Figure 1 As shown, the ECALL-based vehicle ECU detection method includes:

[0041] The detection commands compiled by the vehicle information service provider platform are sent to the network communication service provider platform;

[0042] Furthermore, such as Figure 2 In the process of connecting the OEM's TSP platform to the telecommunications operator, the vehicle information service provider platform generates a detection command in SMS format based on the target vehicle's Vehicle Identification Number (VIN) and sends the detection command to the network communication service provider platform.

[0043] The detection information corresponding to the detection command sent by the network communication service provider platform is sent to the vehicle emergency call system of the target vehicle corresponding to the detection command.

[0044] Furthermore, such as Figure 2 In the process from the telecommunications operator to the ECALL system, after receiving the detection command sent by the vehicle information service provider platform, the network communication service provider platform parses the detection command to obtain the detection information corresponding to the detection command, and sends the detection information to the vehicle emergency call system of the target vehicle corresponding to the vehicle identification code by calling the SMS delivery interface based on the vehicle identification code included in the detection information.

[0045] Send the diagnostic command message corresponding to the detection information sent by the vehicle's onboard emergency call system to the vehicle's onboard control module.

[0046] Furthermore, such as Figure 2 In the process of connecting the ECALL system to the vehicle ECU, after receiving the detection information sent by the network communication service provider platform, the vehicle's emergency call system parses the detection information to obtain the diagnostic content included in the detection information, generates a corresponding diagnostic command message based on the diagnostic content, and then sends the diagnostic command message to the vehicle's on-board control module. The diagnostic command message is a message generated according to the automotive electronic diagnostic communication standard protocol.

[0047] The diagnostic information corresponding to the diagnostic command message sent by the vehicle control module of the target vehicle is sent to the vehicle emergency call system of the target vehicle.

[0048] Furthermore, such as Figure 2 In the process of transmitting the vehicle's ECU to the ECALL system, after receiving the diagnostic command message sent by the vehicle's onboard emergency call system, the vehicle's onboard control module obtains the diagnostic information of the target vehicle corresponding to the diagnostic command message and sends the diagnostic information to the vehicle's onboard emergency call system.

[0049] The service information corresponding to the diagnostic information sent by the vehicle's onboard emergency call system is sent to the vehicle information service provider platform via the network communication service provider platform.

[0050] Furthermore, such as Figure 2 In the process of connecting the ECALL system to the vehicle manufacturer's TSP platform, after receiving the diagnostic information sent by the vehicle's onboard control module, the vehicle's onboard emergency call system compiles the diagnostic information into service information in SMS format and sends the service information to the network communication service provider platform. After receiving the service information sent by the vehicle's onboard emergency call system, the network communication service provider platform sends the service information to the vehicle information service provider platform. After receiving the service information, the vehicle information service provider platform performs content analysis on the service information to detect and analyze the ECU information.

[0051] The present invention relates to an ECALL-based vehicle ECU detection method. The vehicle information service provider sends a compiled detection command to a network communication service provider. Upon receiving the detection command, the network communication service provider generates detection information corresponding to the command and sends it to the vehicle's emergency call system. The vehicle's emergency call system receives the detection information, parses it to obtain a diagnostic command message, and sends it to the vehicle's control module. Upon receiving the diagnostic command message, the vehicle's control module obtains the diagnostic information corresponding to the message and sends it to the vehicle's emergency call system. The vehicle's emergency call system receives the diagnostic information, compiles it into service information, and then... The method involves sending commands from a network communication service provider to a vehicle information service provider to remotely acquire vehicle ECU information in vehicles without a T-BOX via the vehicle emergency call system. This method obtains vehicle ECU information without requiring pre-installed diagnostic configuration items. Furthermore, because the ECALL-based vehicle ECU detection method transmits the detection and acquisition commands via a network communication service provider, it can acquire vehicle ECU information even in poor network conditions, such as when only 2G networks are supported. In contrast, existing methods for acquiring ECU information via T-BOX require better network conditions, such as 4G or 5G. Therefore, the vehicle ECU acquisition method of this invention has lower dependence on the network environment and fewer application limitations.
