Description

Technical Field

[0001] This disclosure relates to the field of automotive control technology, specifically to a dual EOL configuration system for automotive control modules with switching functionality and its implementation method. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] In recent years, with the booming development of the automotive industry, vehicle configurations have become increasingly diverse and varied, requiring accurate and rapid identification of these configurations. Therefore, end-of-life (EOL) configurations have become increasingly important in the automotive production and after-sales process.

[0004] Existing EOL (End of Service) configuration functions are relatively limited and cannot fully cover various scenarios in automotive development and after-sales service. The limitations of a single EOL function in specific situations exist. Currently, traditional OEMs generally use diagnostic EOL methods, writing the information directly into the ACU (Autonomous Unit) using a diagnostic tool based on the vehicle's configuration information. This method is time-consuming and impacts production line efficiency.

[0005] In practical applications, this single-function EOL configuration method cannot achieve flexible switching in different scenarios. It not only fails to meet complex and ever-changing needs, but also leads to a waste of production lines and human resources. Summary of the Invention

[0006] To address the aforementioned issues, this disclosure proposes a dual EOL configuration system for automotive control modules with switching capabilities and its implementation method. It introduces two methods: CAN EOL and diagnostic EOL. By completing the signal interaction between various components and enabling flexible switching in different scenarios during the processes of command transmission, signal transmission, signal verification, configuration verification, command reception, and signal reception, the system ensures the accuracy of information throughout the entire process.

[0007] According to some embodiments, the present disclosure adopts the following technical solutions: The method for implementing a dual EOL configuration for a vehicle control module with switching capabilities includes: Two configuration strategies are introduced: CAN EOL and Diagnostic EOL. When configuring vehicles in different scenarios, determine the priority of the two configuration strategies, CAN EOL and Diagnostic EOL, and switch to implement the configuration strategy with higher priority. Within the set time period for sending task configuration, only BCM communication configuration is responded to, meaning CAN EOL configuration has a high priority. During the time period when no task configuration is sent, EOL configuration diagnosis is faster than BCM communication configuration, meaning EOL configuration diagnosis has a high priority.

[0008] According to some embodiments, the present disclosure adopts the following technical solutions: A dual EOL configuration system for automotive control modules with switching capabilities includes: The initialization configuration module is used to introduce two configuration strategies: CAN EOL and Diagnostic EOL. The configuration execution module is used to determine the priority of the two configuration strategies, CAN EOL and Diagnostic EOL, when configuring vehicles in different scenarios, and switch to implement the configuration strategy with higher priority. Within the set time period for sending task configuration, only BCM communication configuration is responded to, meaning CAN EOL configuration has a high priority. During the time period when no task configuration is sent, EOL configuration diagnosis is faster than BCM communication configuration, meaning EOL configuration diagnosis has a high priority.

[0009] According to some embodiments, the present disclosure adopts the following technical solutions: A computer program product includes a computer program that, when executed by a processor, implements the dual EOL configuration implementation method for an automotive control module with switching function.

[0010] According to some embodiments, the present disclosure adopts the following technical solutions: A non-transitory computer-readable storage medium is provided for storing computer instructions, which, when executed by a processor, implement the dual EOL configuration implementation method of the vehicle control module with switching function.

[0011] According to some embodiments, the present disclosure adopts the following technical solutions: An electronic device includes a processor, a memory, and a computer program; wherein the processor is connected to the memory, the computer program is stored in the memory, and when the electronic device is running, the processor executes the computer program stored in the memory to enable the electronic device to implement the dual EOL configuration implementation method of the vehicle control module with switching function.

[0012] Compared with the prior art, the beneficial effects of this disclosure are as follows: The disclosed method for implementing dual EOL configuration of automotive control modules with switching function introduces two methods: CAN EOL and diagnostic EOL. By completing the signal interaction between various components and flexibly switching between different scenarios during the stages of command sending, signal sending, signal verification, configuration verification, command receiving, and signal receiving, the accuracy of information throughout the entire process is ensured.

[0013] This disclosed method for implementing dual EOL configuration of an automotive control module with switching capability involves sending vehicle configuration information via a diagnostic tool, sending CAN EOL configuration frames via the BCM, and receiving CAN configuration frames and diagnostic commands via the ACU, enabling switching between CAN EOL and diagnostic EOL. Depending on the scenario and vehicle model, users can choose a simple and quick method to write the configuration words, thereby saving significant labor costs.

[0014] This disclosed method for implementing dual EOL configuration of an automotive control module with switching functionality allows for rapid configuration of the entire vehicle controller. In a production line scenario, the diagnostic tool sends the vehicle configuration code to the BCM, which then sends the configuration code to each ECU, including the ACU (Airbag Controller). In a factory scenario, after a vehicle rolls off the production line, the ACU may malfunction, requiring configuration word changes to resolve some issues. In this case, both CAN EOL and diagnostic EOL methods can be chosen. CAN EOL requires changing the vehicle configuration code in the company system and scanning the configuration QR code with a diagnostic tool, which is time-consuming. Diagnostic EOL is generally preferred, using a diagnostic tool or CAN diagnostic tool to quickly configure the configuration word using 2E services, thus resolving configuration issues quickly. In an aftermarket scenario, after replacing the ACU, CAN EOL configuration is required to directly activate the configuration word, saving time and costs. Attached Figure Description

[0017] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0018] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Example 1 One embodiment of this disclosure provides a method for implementing a dual EOL configuration for an automotive control module with switching functionality, including: Step 1: Introduce two configuration strategies: CAN EOL and Diagnostic EOL; Step 2: When configuring vehicles in different scenarios, determine the priority of the two configuration strategies, CAN EOL and Diagnostic EOL, and switch to implement the configuration strategy with higher priority. Within the set time period for sending task configuration, only BCM communication configuration is responded to, meaning CAN EOL configuration has a high priority. During the time period when no task configuration is sent, EOL configuration diagnosis is faster than BCM communication configuration, meaning EOL configuration diagnosis has a high priority.

[0021] As one example, EOL configuration mainly includes two types: CAN EOL and diagnostic EOL. These two EOL methods can be used alternately according to different application scenarios to quickly and accurately resolve configuration-related issues. These scenarios include production line flashing, factory assembly issues, and after-sales handling. Specifically, CAN EOL requires production line equipment or a diagnostic tool. The diagnostic tool writes the ACU (Airbag Control Unit) configuration code to the BCM (Body Control Module). The BCM then sends the configuration frame to the ACU via the CAN (Controller Area Network) line, thus supporting configuration word writing to the ACU. Diagnostic EOL requires a diagnostic tool or a CAN diagnostic tool. The diagnostic tool directly writes the configuration code into the ACU, enabling ACU configuration word writing. The tools used for CAN EOL configuration include production line equipment or a diagnostic tool, while the tools used for diagnostic EOL configuration are a diagnostic tool or a CAN diagnostic tool. The diagnostic tool sends the vehicle configuration information, the BCM sends the CAN configuration frame, and the ACU receives the CAN configuration frame and diagnostic commands. The specific implementation process is as follows: Step 1: Introduce two configuration strategies: CAN EOL and Diagnostic EOL; Specifically, step 1.1: The specific process of CAN EOL configuration includes: (1) Before the project is developed, determine the technical solution for CAN EOL, namely the EOL configuration process.

[0022] (2) The ACU is configured with 0X00 at the factory and reports the corresponding DTC (Diagnostic Trouble Code).

[0023] (3) Use a diagnostic tool to write the configuration word into the BCM.

[0024] (4) The BCM sends the 0X5F0 signal to send the configuration information to the ACU. The ACU receives the complete configuration information once every 1 second, for a total of twice, and the two configuration information must be consistent.

[0025] (5) After a series of pre-flash checks, the configuration information is written to the ACU.

[0026] (6) After the ACU writes the configuration word, it locks the configuration word after detecting no DTC.

[0027] (7) After the configuration word is locked, the ACU will no longer process the configuration frames sent by the BCM.

[0028] (8) If you need to reconfigure CAN EOL, you need to reactivate EOL configuration. The activation command is 31 01 64 1F.

[0029] Step 1.2: The specific process for diagnosing the EOL configuration includes: (1) Before the project is developed, determine the technical solution for diagnosing EOL, i.e. the EOL configuration process.

[0030] (2) After entering secure access, the ACU performs a series of pre-flash checks. After passing the checks, it proceeds to the next step.

[0031] (3) The diagnostic instrument sends 2E 6417 + configuration word. After the success is displayed, the configuration word is successfully written and locked.

[0032] Step 2: When configuring vehicles in different scenarios, determine the priority of the two configuration strategies, CAN EOL and Diagnostic EOL, and switch to implement the configuration strategy with higher priority. Within the set time period for sending task configuration, only BCM communication configuration is responded to, meaning CAN EOL configuration has a high priority. During the time period when no task configuration is sent, EOL configuration diagnosis is faster than BCM communication configuration, meaning EOL configuration diagnosis has a high priority.

[0033] Specifically, the priority determination process for CAN EOL configuration and diagnostic EOL configuration includes: 1. Within 8 seconds of sending the unlock configuration (31 01 64 1F), only the BCM communication configuration is responded to, i.e., the CAN configuration has a higher priority.

[0034] 2. During the period when no unlock configuration (31 01 64 1F) is sent, diagnostic configuration > BCM communication configuration, that is, diagnostic configuration has higher priority.

[0035] 3. Once the diagnostic configuration is complete, the BCM cannot be reverted; the BCM configuration can only be activated by re-unlocking the BCM communication configuration (31 01 64 1F), meaning the diagnostic configuration has a high priority.

[0036] Furthermore, the specific procedures for CAN EOL configuration and diagnostic EOL configuration are as follows: (1) The configuration word is not locked after the ACU self-test failure. After the diagnostic configuration is successfully executed, the configuration word is locked; thereafter, the ACU will ignore all BCM frames.

[0037] (2) The ACU self-test has not locked the configuration. After the diagnostic configuration is successfully executed, the configuration word will be locked in advance; thereafter, the ACU will ignore all BCM frames.

[0038] (3) After the ACU completes the self-test and locks the configuration word, the configuration word remains locked even after the diagnostic configuration is successfully executed.

[0039] As one example, the two EOL methods are applicable to different scenarios and can be switched between each other in different scenarios. The specific switching process includes: CASE 1: After an ACU self-test failure, the configuration word is not locked. After successful diagnostic configuration, the configuration word is locked; thereafter, all BCM frames will be ignored. CASE 2: The ACU self-test has not yet locked the configuration. After the diagnostic configuration is successfully executed, the configuration word will be locked in advance; thereafter, all BCM frames will be ignored. CASE 3: ACU completes self-test and locks the configuration word. Even after successful diagnostic configuration, the configuration word remains locked. CASE 4: When the EOL configuration word is locked during diagnosis, activating CAN EOL will change the configuration word and lock it.

[0040] Example 2 One embodiment of this disclosure provides a dual EOL configuration implementation system for an automotive control module with switching functionality, including: The initialization configuration module is used to introduce two configuration strategies: CAN EOL and Diagnostic EOL. The configuration execution module is used to determine the priority of the two configuration strategies, CAN EOL and Diagnostic EOL, when configuring vehicles in different scenarios, and switch to implement the configuration strategy with higher priority. Within the set time period for sending task configuration, only BCM communication configuration is responded to, meaning CAN EOL configuration has a high priority. During the time period when no task configuration is sent, EOL configuration diagnosis is faster than BCM communication configuration, meaning EOL configuration diagnosis has a high priority.
