EMC VAlidation of Multi-Sensor systems (eVAMS)
Purpose and goal
EMC testing of autonomous vehicles is challenging because the involved systems are designed to identify unrealistic driving conditions, which is exactly what we have in a typical anechoic EMC chamber. When the system detects unrealistic conditions, autonomous driving functions are disabled or set to predefined states, which means that EMC testing of autonomous functions is not possible. To fully test autonomous driving systems, we therefore need to emulate a realistic environment in many aspects, i.e., we need to stimulate involved sensors in a realistic way.
Expected results and effects
In the project, it was demonstrated that it is possible to stimulate radars and cameras used for active safety systems, and to simulate the vehicle position by transmitting a synthetic GNSS (Global Navigation Satellite System) signal in the chamber, so that realistic EMC testing of a complete vehicle can be done for systems using these sensors.
Planned approach and implementation
The partners Volvo Car Corporation, Rise and Provinn, initiated this project partly financed by Vinnova within the FFI-program. The eVAMS project (diarienr. 2015-06892) was a FFI project within the Electronics, Software and Communications program. eVAMS was an 18 month project that started 2016-03-01 and ended 2017-09-30. The project had a total budget of 2 MSEK.
