Research on Radiated Immunity Test Methods for ADAS Functions Considering Vehicle In-the-Loop

The radiated immunity of passenger cars and commercial vehicles is validated using electromagnetic interference from off-vehicle radiation sources in an anechoic chamber according to the procedure ISO 11451-2. Common electrical or electronic vehicle systems, including dual flash, monitors, entertainment must be a standardized evaluation procedure. However, Automated Driver Assistance System (ADAS) functions often lack verification complex fields, which might create potential risk due compatibility problems. For example, radar camera sensors based on autonomous emergency braking (AEB), adaptive cruise control (ACC), lane departure warning (LDW) may ineffective real world if subjected interference. This paper presents new methodology evaluate performance main ADAS functions. A target simulator virtual driving environment are designed trigger AEB, ACC, LDW chamber. Moreover, In-the-Loop (VHIL) conception also applied by acquiring analyzing key ADAS-related signals. reliability at whole-vehicle level can evaluated improved external sources.
