102 enormous costs and efforts for validation and release. Especially the short period between updates results in the fact that the validation of new software versions based on real vehicles can only be implemented to a very limited extent. The use of virtual prototypes enables agile development and validation between quality gates and hence contributes significantly to the reliable provision of OTA updates. Due to the sheer complexity of the test scenarios as well as the enormous number of test cases to be tested, it is necessary to scale the use of simulation to enable fast iteration cycles. Various methods are suitable for this purpose, which entail different prerequisites in terms of infrastructure. Scaling can be realized locally through high-performance computing (HPC) or based on cloud technology. Simulation can thus be fully utilized for broad software tests in order to process extremely large test scopes in a short time. The solutions presented make a significant contribution to optimizing the transformation process in the automotive industry. Through virtual test driving and the introduction of proven software development methods, the development process can be adapted to meet the challenges and ensure functional safety. Engineering Partner Establishing a Continuous and Agile Vehicle Development Process By Martin Herrmann, Business Development Manager ADAS & Automated Driving, IPG Automotive GmbH Due to the trend towards the software-defined vehicle, the biggest shifts in the automotive industry are no longer taking place in the traditional fields of automotive engineering but primarily in the areas of software and the respective control units. This development is leading to a significant increase in complexity with regard to testing and validation of assistance functions, as they no longer have to act in a domain-specific manner but on an interdisciplinary level. Key issues related to automated driving add new specific challenges, especially with regard to functional safety. It is therefore necessary to look at the overall system both in the context of the full vehicle and in realistic scenarios. Accordingly, a stronger focus on the overall vehicle system – systems engineering to be precise – is imperative. The requirement to provide software updates over-the-air (OTA) during the product lifecycle considerably reduces the time available for development and testing. To meet these challenges and master the complexity, it is necessary to adapt existing development processes and establish new development approaches. The basis for this is virtual test driving, which has become indispensable in vehicle development. The simulation platform CarMaker enables development and continuous testing already at very early development stages up to the validation in the full vehicle. The system under test is integrated into the so-called virtual prototype and tested in realistic scenarios throughout every stage of the development process. Virtual prototypes are fully-fledged digital twins of real-world vehicles. They form the basis for integrating modern software development methods such as continuous integration, testing and deployment (CI/CT/CD) into the development process. In this way, they pave the way for digital transformation and thus for the next innovation leap in virtual vehicle development. Virtual test driving is one of the most important tools to realize the OTA updates mentioned at the beginning and to ensure their functional safety. These updates make further developments and entirely new functions accessible to the driver at the push of a button. At the same time, however, this means that each vehicle is subject to continuous change, which is associated with IPG Automotive GmbH https://ipg-automotive.com/en Image: © IPG Automotive GmbH Share
