Methodology to Validate the Radiated Immunity of Very Complex Systems by a Succession of Simple Component Radiated Immunity Tests at System Level

Abstract

The validation of automotive autonomous and complex functions will be crucial in the coming years. The cost and duration of EMC immunity tests are constantly increasing with the number of functions to validate. In addition, the more complex are the functions, the more difficult will be their validation. Currently, the immunity validation tests for complete electrical functions or architectures at vehicle level are performed indoor on a roller-bench in a semi-anechoic chamber. These complex systems rely on several sensors such as radars, cameras, etc. To perform the immunity validation tests of these systems, one needs therefore to recreate the outdoor scenarios indoor, by stimulating the different sensors, and most of all, by synchronizing these stimulations between each other. However, synchronizing the stimulation of all the sensors in a realistic way is very challenging. Furthermore, autonomous functions will automatically disable themselves in case of incoherencies in the data and information provided by the sensors and the external communication links (e.g. Car-to-X). Therefore, the current methodology will not allow one to validate these complex autonomous functions as desired. In this paper, a new methodology to validate the radiated immunity of complex systems is investigated. The aim of this methodology is to validate automotive electrical functions independently of their level of complexity. This methodology is based on a succession of simple component radiated immunity tests performed directly on vehicle.
