In order to avoid the influence of adaptive cruise control system (ACC) on ride comfort and traffic flow, a hierarchical control strategy is proposed. The prediction model for the preceding vehicle and following vehicle is established. The safety and the ride comfort of the vehicle are taken as the optimisation targets. An upper controller based on model predictive control (MPC) algorithm is constructed to obtain the desired acceleration. In order to prevent switching error between drive torque and brake torque, and improve control accuracy, the lower controller is designed by integral separation PID control algorithm to track the preceding vehicle speed and the safe vehicle spacing distance. The simulation results show that the strategy can effectively control the vehicle speed under rapid acceleration/deceleration condition and steady-state cruising condition, and track the preceding vehicle speed near the safe spacing distance to ensure the safety, high efficiency and ride comfort.
为了避免自适应巡航控制系统(ACC)对乘坐舒适性和交通流量的影响,提出了一种分级控制策略。建立了前车和后车的预测模型。将车辆的安全性和乘坐舒适性作为优化目标。构造了基于模型预测控制(MPC)算法的上位控制器,以获得期望的加速度。为了防止驱动转矩和制动转矩之间的切换误差,提高控制精度,采用积分分离PID控制算法设计了下控制器,以跟踪前车速度和安全车距。仿真结果表明,该策略能够有效控制急加速/减速工况和稳态巡航工况下的车速,并在安全间距附近跟踪前方车速,确保安全、高效和乘坐舒适。

A fine-tuned feature descriptor for pedestrian action recognition in autonomous vehicles 一种用于自动驾驶汽车行人动作识别的微调特征描述符

The autonomous vehicle is the dream project of most of the majestic companies; however, providing a full-fledged autonomous vehicle is very complicated. In this paper, the pedestrian actions are captured using cameras and fine-tuned within a limited amount of time. Certain features of the captured video and their efficient feature descriptors achieve improved accuracy in pedestrian action recognition. The Skeleton based Spatio-Temporal Interest Points (S-STIP) feature is combined with the new interclass discriminative dictionaries. The sparse descriptor is constructed using sparse coding based on orthogonal matching pursuit algorithm and dictionary learning based on Efficient Block Coordinate Descent (EBCD) algorithm. Finally, the sparse descriptor is given as input to the SVM classifier for recognising pedestrian actions. The human action data sets KTH, Weizmann and JAAD are used for experimentation, and the combination of the S-STIP feature and the enhanced sparse descriptor achieves better performance compared to other existing action recognition methods.
自动驾驶汽车是大多数大公司梦寐以求的项目;然而,提供一辆成熟的自动驾驶汽车是非常复杂的。在本文中,行人的动作是用相机捕捉的,并在有限的时间内进行微调。捕获视频的某些特征及其有效的特征描述符提高了行人动作识别的准确性。将基于骨架的时空兴趣点(S-STIP)特征与新的类间判别字典相结合。利用基于正交匹配追踪算法的稀疏编码和基于高效块坐标下降(EBCD)算法的字典学习构造稀疏描述子。最后,将稀疏描述符作为支持向量机分类器的输入,用于识别行人动作。使用KTH、Weizmann和JAAD人体动作数据集进行实验,S-STIP特征与增强的稀疏描述子相结合,比现有的其他动作识别方法获得了更好的性能。

CPAAS: an efficient conditional privacy-preservation anonymous authentication scheme using signcryption in VANET CPAAS:在VANET中使用签名加密的一种高效的条件隐私保护匿名认证方案

Vehicular Ad-Hoc Network (VANET) is a tremendously promising innovation in the field of Intelligent Transportation System (ITS). It facilitates a vehicle to communicate on the road with infrastructure or OBU to increase road safety and driving conditions. Further, to deliver the same requires a secure network build-up through a legitimate entity. However, in an open network, any of the participating entities may be malicious. Therefore we need a proper solution to mitigate the effects of such entities by authenticating them, and it should also preserve the privacy of entity and integrity of message so that the impact of any malicious entity can be nullified. The existing solutions focus on any of the above aspects, but not all, further they are not computationally efficient. Inspired by this, we propose a computationally efficient approach that achieves most of the security requirements with less communication overhead. We have used distributed pseudo_id for preserving the privacy of vehicle and the ID-based Certificateless Signcryption scheme based on elliptic curve cryptography to provide an effective way to achieve mutual authentication, integrity, non-repudiation, and confidentiality. The security analysis of our approach demonstrates the efficiency and effectiveness of our proposed scheme.
车载自组织网络(VANET)是智能交通系统(ITS)领域一个极具发展前景的创新技术。它有助于车辆在道路上与基础设施或OBU进行通信,以提高道路安全和驾驶条件。此外,要提供相同的服务,需要通过合法实体建立安全的网络。然而,在开放的网络中,任何参与的实体都可能是恶意的。因此,我们需要一个合适的解决方案,通过对这些实体进行身份验证来减轻它们的影响,同时还应该保护实体的隐私性和消息的完整性,从而消除任何恶意实体的影响。现有的解决方案侧重于上述任何方面,但不是全部,而且它们的计算效率不高。受此启发,我们提出了一种计算效率高的方法,以较少的通信开销实现大多数安全需求。我们使用分布式pseudo_id来保护车辆的隐私,使用基于id的基于椭圆曲线加密的无证书签名加密方案,为实现相互认证、完整性、不可否认性和保密性提供了有效的途径。对该方法的安全性分析证明了该方案的效率和有效性。
