“…Much research focuses on assessing and improving AV's abilities to recognize and respond to their environments (Hoss et al, 2022). Current efforts predominantly utilize adversarial attacks to test perception modules, identifying deficiencies in traffic participant recognition (Tang et al, 2023), such as tests targeting visual recognition (Chen et al, 2019;Zhao et al, 2019b;Im Choi and Tian, 2022), LiDAR detection (Li et al, 2021;Zhu et al, 2021a,b), and perception fusion (Zhong et al, 2022). Other perception module tests include metamorphic testing (Zhou and Sun, 2019;Wang et al, 2021;Ramanagopal et al, 2018) and combinatorial testing (Gladisch et al, 2020;Cheng et al, 2018), involving sensor data processing and analysis, and vehicular responses to different traffic scenarios, obstacles, and environmental factors.…”
