The importance of data management systems in vehicle development is increasing because the systematic provision of content is crucial for efficient and agile development processes. In order to meet new demands, ZF, together with PDTec and IPG Automotive, is implementing a data management solution for virtual test driving on a global basis.
MOVING TOWARD VIRTUAL DEVELOPMENT
Digitalization in general as well as automated driving in particular poses great challenges for the automotive industry. Moving toward an increase in virtual development is a pivotal factor for success that requires new methods and infrastructures at the same time. Automated vehicles are complex and safetyrelevant systems for which an ideal interaction of sensors, actuators and software is of major importance. An efficient, cross-domain and safe system development in this area necessitates a high degree of simulation [1, 2]. As a result, the number of people working regularly with simulation programs is growing continuously, and workflows need to be integrated sus
tainably into superordinate development processes. A systematic management and an intelligent, distributed use of models, simulation data and test sce narios are playing a key role [3, 4]. The same applies to the integration of scalable computing infrastructures. To meet these and further requirements, ZF has implemented a data management solution for virtual test driving with the support from PDTec and IPG Automotive. The following article is going to elaborate on this solution. AREAS OF DATA MANAGEMENT
A modern enterprise Simulation Data Management (SDM) covers the entire CAE range: from providing data from Product Data Management (PDM) systems like CAD systems to comprehensive
support of CAE processes as well as post-processing and correlation of results. Consequently, some of the hereafter discussed requirements did not necessarily arise in the context of automated driving as they are already met by existing SDM solutions. This being the case, the solution presented here is an extension of the established SDM solution by PDTec [5], which meets the requirements of automated driving in conjunction with the use of the integration and test platform CarMaker from IPG Automotive. The approach is based on centrally providing virtual full vehicles for functional system testing, FIGURE 1. The platform offers a comprehensive and scalable simulation environment for the development of automated driving functions including vehicle, sensor and environment simulation [6]. In the following, the SDM areas which are of particular relevance are described in mo
