New Field Operational Tests Sampling Strategy Based on Metropolis-Hastings Algorithm

Collection and classification of influence parameters for safety effectiveness of ADAS

“…Thirty-one documents (Buehler and Wegener, 2005;Schmidt and Sax, 2009;Staender, 2010;Weitzel and Winner, 2013;Chen et al, 2014;Weitzel, 2014;Kurt et al, 2015;Seiniger and Gail, 2015;Wittmann et al, 2015;Zhang et al, 2015;Ben Abdessalem et al, 2016;Hasirlioglu et al, 2016;Raffaëlli et al, 2016;Doric, 2017;Hasirlioglu et al, 2017;Xia et al, 2017;Zhao et al, 2017;Zhou and Re, 2017;Chelbi et al, 2018,;Chelbi et al, 2019;Chen, 2018;Junietz et al, 2018;Kolk et al, 2018;Sander and Lubbe, 2018;Xia et al, 2018;Antona-Makoshi et al, 2019;Goodin et al, 2019;Kluck et al, 2019;Duan et al, 2020;Koné et al, 2020) were identified. From these studies, the influence parameters that meet one of the following criteria were identified and a preliminary grade (qualitative assessment) was assigned accordingly.…”

Proposal of a new virtual evaluation approach of preventive safety applications and advanced driver assistance functions – application: AEB system

“…A first part (in orange), which includes a description of the studied autonomous emergency braking (AEB) system and of its different evaluation criterions to propose a synthesis of the most relevant test scenarios with the operating parameters of each scenario. A second part (in blue) that deals with the FOT database (SPMD), the implementation of a new sampling strategy (more detailed in our other article [4]) based on Metropolis‐Hastings algorithm and at the end of this part, the implementation of virtual tests on a vehicular software simulator (PreScan). The third part (in green) focuses on collecting of simulation results, then assess the risk of each test, to classify them, and this allows us to recuperate high risk and very high‐risk cases to build a set of worst‐case scenarios.…”

“…This study is based on our proposed sampling strategy in [4]. An appropriate sampling strategy is based on MCMC methods, using Metropolis‐Hastings algorithm to generate samples from probability distributions of FOT; the SPMD in our case.…”

“…For each step of the sampling strategy, we will give a brief explanation in the following subsections. For a more detailed explanation, we strongly suggest referring to our article entitled ‘New Field Operational Tests Sampling Strategy Based on Metropolis‐Hastings Algorithm’ [4].…”
