In the past decade, autonomous driving has gained significant developments with the joint effort from academia and industry. Despite the promising developments, seeing surroundings robustly, perceiving objects in real-time, and acting safely on par with or even better than human drivers remain as the big challenges in achieving full autonomy. In this talk, our recent work on seeing surroundings robustly and acting safely will be presented. For autonomous driving, an essential task is to detect surrounding objects accurately. Most autonomous vehicles are equipped with optical devices, including cameras and light detection and ranging (LiDAR) sensors, to collect environment data in real time. However, those optical devices are vulnerable to optical signal attacks, which could compromise the accuracy of object detection. To address this critical issue, we developed a new technique to detect and identify sensors under attack. Algorithmic motion planning such as sampling based motion planning can generate collision-free trajectory, which, however, may take longer time than the environment changes and generate jerky trajectory. To address such issues, we proposed a new method to reduce the search space of sampling based motion planning and allow longer planning time through prediction of surrounding vehicles’ driving behaviors so that human-like smooth and collision-free trajectory can be generated in shorter computation time.
