VALIDATION SUPPORT FOR DISTRIBUTED VEHICLE DEVELOPMENT BASED ON THE XIL-APPROACH

摘要

The ongoing electrification of the powertrain leads to major structural changes in the automotive development. So far non-automotive technologies obtain more and more key positions in the vehicle development. Therefore a closer and deeper cooperation between OEMs and suppliers or research institutes is expected [1]. The objective of this contribution is to develop a method for planning and designing a distributed validation environment (DVE) to support the challenge of future validation. A DVE describes a validation environment, where at least one part of it (e.g. simulation model, test bench) is off-site. With the aid of a new description model based on the IPEK-X-in-the-Loop-Approach (IPEK-XiL-Approach), which is focused on systemic interdependencies of the validation environments (VE), different forms of DVEs will be modeled. Thereby, the design of suitable DVEs can be supported in the product development process. In collaborative product development the DVEs assist the engineer in creating a continuous validation tool chain from the simulation to testing procedures with physical prototypes. In the context of the product generation development in the automotive industry this is important to take full advantage of the synergy effects between each product generation of each supplier and the OEM [2]. This contribution is only about modeling and methodology for creating DVEs. There is no detailed analysis given about the feasibility of specific DVEs according to the validation objective. The model for describing a DVE supports the corresponding realization. Previous work primarily deals about the feasability of a specific application in the context of the IPEK-XiL-Approach [3]. With the enhanced understanding of DVEs a distributed and collaborative vehicle development can be supported.
