Future Mobility Electromagnetic Reliability Study based on HPVC Degradation Evaluation with Electromagnetic Noise Analysis

The automobile industry is creating a paradigm shift with the following two keywords: Electrification and Autonomous driving. During this process, the roles of multiple controllers are integrated into the central computer, which is known as the HPVC (High Performance Vehicle Computer). The HPVC not only performs autonomous driving but also would be a basic platform of SDV (Software Defined Vehicle) at the same time. In this paper, we propose a method of evaluating the status of the HPVC based on measuring electromagnetic noise emissions from the internal circuit of the HPVC, especially with the near field electromagnetic measurement. As the elements in IC circuit deteriorate, the electromagnetic noise emitted increased according to our analysis. The results show that the proposed method can be used to diagnose possible failures in the early stage, and it can help the improvement of the electromagnetic reliability in future mobility.
