Architect ECA2030

Trustable architectures with acceptable residual risk for the electric, connected and automated cars

The key targets of ArchitectECA2030 are: (a) the robust, mission-validated, traceable design of electronic components and systems (ECS), (b) the quantification of an accepted residual risk of ECS for electronic, connected and automated vehicles to enable type approval, and (c) an increased end-user acceptance due to more reliable and robust ECS. The ILK focused on two main topics in this project: (a) detection of metallic foreign objects within inductive charging systems for the traction battery of electric vehicles and (b) detection of wear and aging of electric drive motors.

Within the first part, passive inductive sensors for detecting foreign objects in an inductive charging system were characterized. For this purpose, the magnetic field of the ground assembly of the charging system was measured, the thermal behavior of standardized test objects in the magnetic field of the ground assembly was determined, a selection of sensor geometries was investigated and improvements were proposed. Based on this, models were created for the charging system and foreign object detection and validated in simulations with the measurement results. These models enable the virtual development and assessment of such systems.

Within the second part, imbalances of the rotor were systematically introduced into an electric motor and detected by measuring the mechanical vibrations of the end shield. For this purpose, sensors were structurally integrated into the motor's end shield. From the measurement results, load states of the motor were determined and assessed based on the vibration frequencies involved.
