Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted information detection, and in particular to an ECALL-based vehicle-mounted ECU detection method, device and medium. Background Art

[0002] The current detection method of vehicle ECU (Electronic Control Unit) information is based on T-BOX (Telematics BOX, vehicle remote communication module, is an important part of the Internet of Vehicles system. The vehicle T-BOX connects to the gateway and the vehicle network through the CAN transceiver to communicate with other ECU data, and communicates with the vehicle enterprise service provider back-end system through the network to realize data reporting). Unified Diagnostic Service (UDS) is a standardized on-board diagnostic protocol used to implement communication between diagnostic equipment (such as diagnostic instruments and on-board systems) and on-board ECUs to complete diagnostic functions such as fault detection, parameter reading, and program flashing. The diagnostic protocol communicates with other ECUs in the vehicle network. Car companies generally embed the UDS diagnostic configuration corresponding to the vehicle ECU information that the vehicle needs to obtain into the T-BOX. After the car company initiates a diagnostic request through the car company service provider's backend, the T-BOX executes the corresponding diagnostic instructions according to the embedded configuration items and reports the obtained ECU information to the car company service provider's backend, so that the car company can promptly understand the vehicle status and whether there are any faults in the vehicle.

[0003] Therefore, the existing method for detecting and obtaining vehicle-mounted ECU information is to use the vehicle-mounted T-BOX to read the ECU information remotely or through self-diagnosis and report it to the vehicle manufacturer's service provider's backend.

Obviously, the described embodiments are only 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 those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] This application proposes a vehicle-mounted ECU detection method based on ECALL, which is applied to an information detection system. The information detection system includes a vehicle-mounted information service providing platform (such as Figure 2 The car company TSP platform shown in the figure is the Telematics Service Provider platform), the network communication service provider platform (such as Figure 2 The communication operator shown in (i.e., the provider of network services), the vehicle emergency call system (such as Figure 2 ECALL system, Emergency Call system) and vehicle control module (such as Figure 2 The on-board ECU shown in FIG), wherein the on-board emergency call system integrates the diagnostic service function of the automotive electronic diagnostic communication standard protocol (UDS protocol) to support the sending of UDS protocol messages.

[0019] Among them, such as Figure 1 As shown, the vehicle-mounted ECU detection method based on ECALL includes: Sending the detection instructions compiled by the vehicle information service provider platform to the network communication service provider platform; Further, if Figure 2 In the step from the automaker's TSP platform to the communication operator, the in-vehicle information service provider platform generates a detection instruction in SMS format based on the vehicle identification number (VIN) of the target vehicle, and sends the detection instruction to the network communication service provider platform.

[0020] Sending the detection information corresponding to the detection instruction sent by the network communication service provider platform to the on-board emergency call system of the target vehicle corresponding to the detection instruction; Further, if Figure 2 In the step of connecting the communication operator to the ECALL system, the network communication service provider platform parses the detection instruction after receiving the detection instruction sent by the in-vehicle information service provider platform to obtain the detection information corresponding to the detection instruction, and according to the vehicle identification code included in the detection information, sends the detection information to the in-vehicle emergency call system of the target vehicle corresponding to the vehicle identification code by calling the SMS sending interface.

[0021] Sending the diagnostic command message corresponding to the detection information sent by the on-board emergency call system of the target vehicle to the on-board control module of the target vehicle; Further, if Figure 2 In the step of ECALL system to on-board ECU, the on-board emergency call system of the target vehicle parses the detection information after receiving the detection information sent by the network communication service provider platform to obtain the diagnostic content included in the detection information, and generates a corresponding diagnostic instruction message based on the diagnostic content, and then sends the diagnostic instruction message to the on-board control module of the target vehicle, wherein the diagnostic instruction message is a message generated according to the automotive electronic diagnostic communication standard protocol.

[0022] Sending the diagnostic information corresponding to the diagnostic command message sent by the on-board control module of the target vehicle to the on-board emergency call system of the target vehicle; Further, if Figure 2 In the step of on-board ECU to ECALL system, after receiving the diagnostic command message sent by the on-board emergency call system of the target vehicle, the on-board control module of the target vehicle obtains the diagnostic information of the target vehicle corresponding to the diagnostic command message according to the diagnostic command message, and sends the diagnostic information to the on-board emergency call system of the target vehicle.

[0023] The service information corresponding to the diagnostic information sent by the on-board emergency call system of the target vehicle is sent to the on-board information service providing platform via the network communication service providing platform.

[0024] Further, if Figure 2In the step of transmitting from the ECALL system to the vehicle manufacturer's TSP platform, the target vehicle's on-board emergency call system compiles the diagnostic information into service information in SMS format after receiving the diagnostic information sent by the target vehicle's on-board control module, and sends the service information to the network communication service provider platform. After receiving the service information sent by the target vehicle's on-board emergency call system, the network communication service provider platform sends the service information to the on-board information service provider platform. After receiving the service information, the on-board information service provider platform performs content analysis on the service information to detect and analyze the ECU information.

[0025] The vehicle-mounted ECU detection method based on ECALL of the present invention is as follows: the vehicle-mounted information service providing platform sends the compiled detection instruction to the network communication service providing platform; after receiving the detection instruction, the network communication service providing platform generates detection information corresponding to the detection instruction and sends it to the vehicle-mounted emergency call system of the target vehicle corresponding to the detection instruction; the vehicle-mounted emergency call system of the target vehicle parses the detection information after receiving it, obtains the diagnosis instruction message corresponding to the detection information, and sends it to the vehicle-mounted control module of the target vehicle; after receiving the diagnosis instruction message, the vehicle-mounted control module of the target vehicle obtains the diagnosis information corresponding to the diagnosis instruction message of the target vehicle, and sends it to the vehicle-mounted emergency call system of the target vehicle; after receiving the diagnosis information, the vehicle-mounted emergency call system of the target vehicle compiles the diagnosis information into service information. It is sent by the network communication service provider platform to the on-board information service provider platform, so as to realize the purpose of remotely obtaining on-board ECU information in vehicles without T-BOX installed through the on-board emergency call system. The vehicle ECU information can be obtained without the need for pre-embedded diagnostic configuration items. Moreover, the on-board ECU detection method based on ECALL of the present application transmits the detection and acquisition instructions of on-board ECU information through the network communication service provider platform. Therefore, in the case of poor network conditions, such as when only 2G network is supported, the on-board ECU information can also be obtained. The existing method of obtaining ECU information through T-BOX needs to be implemented in scenarios with better network conditions such as 4G or 5G. Therefore, the on-board ECU acquisition method of the present invention has low dependence on the network environment and low application limitations.
