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

Abstract

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

A Survey on Testbench‐Based Vehicle‐in‐the‐Loop Simulation Testing for Autonomous Vehicles: Architecture, Principle, and Equipment

“…Although the authenticity of the road conditions simulated by testbenches may be slightly lower, the simulation errors between field‐based testing and testbench‐based testing have no significant impacts on the testing results. Furthermore, testbench‐based VIL is also able to enable the combination with sensor‐in‐the‐loop testing to generate precise physical sensor data for the AVUT, [ 113 ] which can provide more realistic test cases and further enhance testing accuracy. Finally, as testbench‐based VIL is generally carried out in a laboratory environment, it is safer to comprehensively validate the functionalities and overall performance of the AVUT, which contributes to enhancing testing quality.…”

Validation of Automated Driving Function Based on the Apollo Platform: A Milestone for Simulation with Vehicle-in-the-Loop Testbed

“…Subsequently, the use of simulation software to create a virtual environment was demonstrated to be a more efficient approach for validation in [13][14][15]. A co-simulation framework has been proposed to enhance the simulation scenario, enabling sensor stimulation on the testbed [16,17]. Although this type of bench was initially designed for emission tests, it has been extended to validate ADAS and can facilitate sensor stimulation due to its cost-effectiveness.…”
