Research on quality management strategy of automotive software based on agile iteration

With the tide of “software defined car”, this paper analyzes the importance of software from the dimension of vehicle architecture, and puts forward a new vehicle architecture such as “SDA six-tier architecture”. In order to ensure the efficiency and quality of vehicle software delivery, this paper proposes a development model based on agile iteration, from agile iterative development process, vehicle software integration, as well as integrated IT quality management tools and set process quality objectives. Through 7 iterations of pilot projects, on the basis of the brand new architecture platform and the brand new Software R&D mode, the quality state of the traditional project at the same time is achieved, and the individual quality index is better than that of the traditional project. This quality management approach has also changed from focusing on version of the test bug to software integration process bug quickly solving. Through the setting of Dx iterative process quality valve, with the help of IT tool chain, integration process problems can be quickly located and tracked, and the software defects can be moved forward and the release delivery risk can be greatly reduced. It provides a good reference for automotive software quality management and achieves the research goal.
