Simulating an Autonomous System in CARLA using ROS 2

arXiv.org Artificial Intelligence

Abstract--Autonomous racing offers a rigorous setting to stress test perception, planning, and control under high speed and uncertainty. This paper proposes an approach to design and evaluate a software stack for an autonomous race car in CARLA: Car Learning to Act simulator, targeting competitive driving performance in the Formula Student UK Driverless (FS-AI) 2025 competition. Optimized trajectories are computed considering vehicle dynamics and simulated environmental factors such as visibility and lighting to navigate the track efficiently. The complete autonomous stack is implemented in ROS 2 and validated extensively in CARLA on a dedicated vehicle (ADS-DV) before being ported to the actual hardware, which includes the Jetson AGX Orin 64GB, ZED2i Stereo Camera, Robosense Helios 16P LiDAR, and CHCNA V Inertial Navigation System (INS). The Formula Student Driverless (FS-AI) competition has stimulated research on autonomous racing software stacks validated through both real world testing and simulation.


A Sim-to-Real Vision-based Lane Keeping System for a 1:10-scale Autonomous Vehicle

arXiv.org Artificial Intelligence

Abstract--In recent years, several competitions have highlighted the need to investigate vision-based solutions to address scenarios with functional insufficiencies in perception, world modeling and localization. This article presents the Vision-based Lane Keeping System (VbLKS) developed by the DEI-Unipd Team within the context of the Bosch Future Mobility Challenge 2022. The main contribution lies in a Simulation-to-Reality (Sim2Real) GPS-denied VbLKS for a 1:10-scale autonomous vehicle. In this VbLKS, the input to a tailored Pure Pursuit (PP) based control strategy, namely the Lookahead Heading Error (LHE), is estimated at a constant lookahead distance employing a Convolutional Neural Network (CNN). Bosch Engineering Center in Cluj (RO), represents a recent addition to this landscape, further strengthened by its collaboration I. Introduction This international technical competition invites teams of students to develop Research on Autonomous Vehicles (AVs) has experienced an autonomous driving algorithms on 1:10 scale vehicles, in an increasingly significant growth of interest in the last few years environment that mimics a miniature smart city (see Figure 1). Anyway, due to its Team within the context of the BFMC 2022, showcasing its complexity, there are still many technical and social challenges pivotal role in the team's victory.


A Comprehensive Survey of PID and Pure Pursuit Control Algorithms for Autonomous Vehicle Navigation

arXiv.org Artificial Intelligence

The autonomous driving industry is experiencing unprecedented growth, driven by rapid advancements in technology and increasing demand for safer, more efficient transportation. At the heart of this revolution are two critical factors: lateral and longitudinal controls, which together enable vehicles to track complex environments with high accuracy and minimal errors. This paper provides a detailed overview of two of the field's most commonly used and stable control algorithms: proportional-integral-derivative (PID) and pure pursuit. These algorithms have proved useful in solving the issues of lateral (steering) and longitudinal (speed and distance) control in autonomous vehicles. This survey aims to provide researchers, engineers, and industry professionals with an in depth understanding of these fundamental control algorithms, their current applications, and their potential to shape the future of autonomous driving technology.
