Description

TECHNICAL FIELD

[0001] The present application relates to the field of automotive electronics and software management, and in particular, to a system and method for improving the efficiency of vehicle software management. BACKGROUND

[0002] With the continuous improvement of the intelligence and networking of automobiles, the complexity of vehicle software is growing exponentially. The current industry is facing a series of key technical challenges in the whole life cycle management of vehicle software. Vehicle software is composed of a large number of dispersed and heterogeneous electronic control unit (ECU) software components, which come from different suppliers, use different technology stacks, and have different development standards / protocols, resulting in highly fragmented software management.

[0003] The existing management method mainly relies on the dispersed delivery of suppliers and the software systems maintained by the vehicle manufacturers themselves, and lacks uniformity and end-to-end traceability. Typical problems include:

[0004] Fragmented swamp: a single vehicle contains more than 50 ECUs, and these ECU systems come from more than 20 different suppliers, with more than 100 software components and complex version dependency relationships like a mesh structure. Software information is stored in multiple independent systems, and there is a lack of centralized and unified management.

[0005] Insufficient compliance: for example, the UNECE R156 regulation requires the whole life cycle traceability of vehicle software versions, but the current sampling rate is less than 60%.

[0006] Data chain breakage: the EOL flashing on the production line, the dealer diagnostic instrument, and the user OTA are all in different systems, and the average time spent on software problem tracing is more than 72 hours.

[0007] The existing technical solutions mainly target the local links of software uploading, storage, and distribution, and fail to provide a central management platform covering the whole life cycle, so they cannot effectively solve the above-mentioned systematic problems. SUMMARY

[0008] In view of the defects in the prior art, the purpose of the present application is to provide a system and method for improving the efficiency of vehicle software management, which has a centralized management platform with uniformity, intelligence, real-time performance, and end-to-end traceability, improves the efficiency of vehicle software package management, quickly meets the safety compliance requirements, and realizes the unified management of vehicle ECU software.

[0009] To achieve the above technical effects, the present application adopts the following technical solutions:

[0010] According to a first aspect of the present application, a system for improving the efficiency of vehicle software management is provided, comprising:

[0011] a software package storage module configured to centrally and uniformly store software packages of various stages of a vehicle and establish a standard permission control mechanism;

[0012] a test task distribution module configured to automatically generate test tasks and distribute the test tasks to test personnel or a test system after uploading of the software packages;

[0013] a software and hardware separation management module configured to maintain a correspondence between software versions and hardware BOM structures through a configuration matrix to realize decoupling management of software and hardware;

[0014] a software release module configured to review software to ensure completeness and accuracy and automatically convert the software to a releasable state after passing the review;

[0015] a data automatic distribution module configured to distribute software data to downstream systems, including an OTA platform, a diagnostic instrument and other related platforms, in real time after release of the software.

[0016] Optionally, the software package storage module further includes a version checking unit and a metadata registration unit configured to check completeness and consistency of uploaded software packages and store metadata information.

[0017] Optionally, the test task distribution module automatically assigns test tasks according to a preset priority rule or a task scheduling strategy based on an AI algorithm.

[0018] Optionally, the review process of the software release module includes multiple review nodes configured to check completeness, compatibility and compliance of software packages.

[0019] Optionally, the data automatic distribution module supports a multi-channel parallel distribution mechanism to ensure real-time and consistency of data distribution.

[0020] According to a second aspect of the present application, a method for improving management efficiency of vehicle software is provided, which is implemented by using the above system and includes the following steps:

[0021] Step 1: centrally store ECU software packages of various stages of a vehicle and perform version checking, permission management and metadata registration;

[0022] Step 2: automatically generate test tasks and distribute the test tasks to test personnel or a test system to complete verification after uploading of the software packages;

[0023] Step 3: maintain a relationship between software and hardware BOM structures through a configuration matrix to realize decoupling of software versions and hardware dependency;

[0024] Step 4: review software and automatically convert the software to a releasable state after passing the review;

[0025] Step five: after the software audit is released, the software data is distributed to downstream systems in real time, including the OTA platform and diagnostic instrument.

[0026] Compared with the prior art, the present application has the following beneficial effects:

[0027] 1. The unified centralized management of the ECU software of the whole vehicle is realized, and information fragmentation is avoided.

[0028] 2. It is ensured that each version of software is completely verified, and the risk of flashing error is reduced.

[0029] 3. The end-to-end traceability meets the compliance requirements and improves the safety.

[0030] 4. The automatic testing and distribution mechanism improves the efficiency and shortens the problem positioning time. BRIEF DESCRIPTION OF DRAWINGS
