Compared with designing multiple independent networks to address various tasks, these systems exhibit reduced overall inference latency by integrating various tasks into a single network. Existing panoptic perception networks often rely on pre-trained classification models as their backbone, which are not tailored for specific tasks, thereby compromising accuracy. To address this, we propose a dual-branch backbone and a wide perception segmentation head, enhancing the effectiveness of the network for autonomous driving applications. This enhanced network can simultaneously perform vehicle object detection, drivable area segmentation, and lane segmentation. Furthermore, to meet the stringent latency requirements of autonomous driving, we implement this network using an FPGA acceleration card. In our experiments using the challenging BDD100K dataset, the model significantly surpasses the baseline in accuracy for all tasks. To satisfy the increased real-time demands, the VCK5000 FPGA is used, which achieves inference speeds approximately 35.2 times faster than GPU-based deployments and about 41.5 times energy efficiency, providing significant advantages in resource-constrained scenarios.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 6","pages":"3697-3704"},"PeriodicalIF":14.3,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this purpose, a suitable Lyapunov characterization of heterogeneous scalable input-to-state stability (sISS) is proposed. To validate the proposed framework, we consider a nonlinear vehicular platooning scenario, involving both longitudinal and lateral dynamics. In contrast to existing approaches in the time-domain, we show the convenience of the spatial domain in realizing vehicle-following behavior on general curved paths: the spatial domain helps to address the well-known ‘cutting-the-corner’ phenomenon on curved paths. This phenomenon, referring to a platoon progressively cutting the curves of the path, is solved via a delay-based platooning policy, suitably designed in the spatial domain. The proposed spatial-domain platooning protocol guarantees scalable input-to-state stability despite the possible heterogeneity of the vehicle dynamics. Comparative simulations are performed to illustrate the advantages of the proposed approach.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 6","pages":"3743-3754"},"PeriodicalIF":14.3,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, through the utilization of relative measurements and information obtained by relying only on its onboard sensors, the strategy achieves the circular formation target enclosing control among fixed-wing UAVs with communication-free mode, effectively addressing and mitigating collision concerns along the circular trajectory.

While the two-branch structure achieves better performance than a single-branch structure, it overlooks inference efficiency. This conflict is increasingly aggressive, as recent works solely pursue higher performance rather than both performance and efficiency. In this paper, we address this issue by improving the performance of efficient single-branch structures. We revisit the reasons causing the performance gap between these structures. For the first time, we reveal the information interference problem in the naive early-fusion strategy adopted by previous single-branch structures. Besides, we find that the domain gap between multispectral images, and weak feature representation of the single-branch structure are also key obstacles for performance. Focusing on these three problems, we propose corresponding solutions, including a novel shape-priority early-fusion strategy, a weakly supervised learning method, and a core knowledge distillation technique. Experiments demonstrate that single-branch networks equipped with these three contributions achieve significant performance enhancements while retaining high efficiency.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 6","pages":"3728-3742"},"PeriodicalIF":14.3,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While some prior works have successfully controlled a vehicle up to the friction limit, generalized autonomous driving in these conditions remains an open problem. Skilled human drivers, however, display exceptional vehicle control in these challenging environments. In particular, rally drivers operate with large sideslip angles and high tire slip to achieve their objective of minimizing time. We directly compare a professional human driver and state-of-the-art autonomous racing controller to reveal dramatic differences in state- and input- space utilization. Inspired by these ideas, we present a motion planning and control framework for autonomous racing in low friction environments. We first develop a vehicle model to capture the dynamics associated with high slip maneuvering. Then, we implement nonlinear model predictive control for online, time optimal trajectory generation. Experimental validation on a frozen lake testing track using a Volkswagen Golf GTI reveals the ability to safely operate beyond limits of conventional vehicle safety systems. The utility of this increased maneuverability is demonstrated when the controller is able to recover from a significant, unexpected disturbance to the yaw dynamics. These results suggest that autonomous vehicles, like skilled human drivers, can leverage increased slip to improve robustness in low friction environments.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 6","pages":"3684-3696"},"PeriodicalIF":14.3,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10681660","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the effectiveness of these tracking operations is crucial in assessing the reliability of both tracking systems and ADAS/AD technologies, especially at the edge-computing level. In this study, we introduce a tracking technique using a collaborative predictive model in a time series, named CoPreMo, aimed at enhancing the reliability of radar system tracking operations. We conducted three experiments with this model on a simulated radar system to track a target's range at varying speeds across three ADAS/AD scenarios.

However, multiple agents must cooperate to complete tasks in complex real-world applications, such as auto-annotating in autonomous driving. The primary challenges lie in how multiple agents effectively communicate and collaborate in a multi-modal environment and how to automatically refine annotating results to reduce human intervention. These challenges also hinder LLMs from fully evolving into embodied intelligent agents. Driven by these motivations, we propose ALGPT, a multi-agent cooperative framework for open-vocabulary multi-modal auto-annotation in autonomous driving. ALGPT dynamically assembles agent teams with different roles, and agents cooperate to complete annotation tasks according to requirements. By leveraging Chain of Thought (CoT) and In-Context Learning (ICL) techniques, ALGPT's reasoning capabilities are enhanced, allowing it to develop suitable plans autonomously without human intervention. Furthermore, drawing from project management standards, we introduce project management documents and Standard Operating Procedures (SOPs), which further align ALGPT's behavior with human expectations and mitigate the impact of GPT illusions caused by the cascading effects of multiple GPTs.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 5","pages":"3644-3658"},"PeriodicalIF":14.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional systems rely on deep learning models trained on large-scale datasets, but this approach can be expensive and impractical. Few-shot object detection (FSOD) offers a potential solution by addressing limited data availability. However, object detectors trained with FSOD frameworks often generalize poorly on classes with limited samples. Although most existing methods alleviate this problem by calibrating either the feature maps or prediction heads of the object detector, none of them, like this work, have proposed a unified, dual calibration strategy that operates in both the latent feature space and the prediction probability space of the object detector. Specifically, we propose to improve representation precision by reducing the variances of feature vectors using highly adaptive centroids learned from ensembles of training features in the latent space. These centroids are employed to calibrate the features and reveal the underlying structure of the latent feature space. Moreover, we further exploit the association between the query and support features to calibrate inaccurate predictions resulting from overfitting or underfitting when fine-tuned with few training samples and low training iterations. Through visualization, we demonstrate that our method produces more discriminative high-level features, ultimately improving the precision of an object detector's predictions. To validate the effectiveness of our approaches, we conduct comprehensive experiments on well-known benchmarks, including PASCAL VOC and MS-COCO, showing considerable performance gains compared to existing works.","PeriodicalId":36532,"journal":{"name":"IEEE Transactions on Intelligent Vehicles","volume":"10 6","pages":"3670-3683"},"PeriodicalIF":14.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
