Reconstructing car shape from a still image 从静止图像重建汽车形状
Gu Yuan, Shuming Tang, Fei-yue Wang
This paper addresses the problem of detecting and recognizing car 3D-contour in the presence of car occlusion from a still image. We proposed a deformable template—Meaning Active Basis Model (mABM) which is a variant of Active Basis Model (ABM). MABMs consists of a small number of Gabor wavelet elements with different locations, orientations and sizes, and every element corresponds some specific part contour of a car. We use mABMs to detect 2D-contours of cars with various colors, sizes and shapes, in the process of detection elements of mABM are allowed to slightly perturb their locations and orientations to get the accurate 2D-contours. After detection, the car 3D shape is reconstructed according to the 2D-contour and the calibrated camera parameters. Another contribution of this paper is a novel technique of handling car occlusion: we coarsely rebuild car 3D-cuboid models according to the detecting result of mABMs, followed by the estimation of the overlap coefficients to separate occluded cars. Experimental results with real world images show that this method is effective in the detection of cars even under severe occlusions.
本文研究了静止图像中存在遮挡的汽车三维轮廓的检测和识别问题。提出了一种可变形模板意义主动基模型(mABM),它是主动基模型(ABM)的一种变体。MABMs由少量不同位置、方向和大小的Gabor小波元组成,每个小波元对应某一特定的汽车零件轮廓。我们使用mABM来检测各种颜色、大小和形状的汽车的二维轮廓,在检测过程中允许mABM的元素对其位置和方向进行轻微的扰动,以获得准确的二维轮廓。检测后,根据二维轮廓和标定后的相机参数重建汽车三维形状。本文的另一个贡献是一种新的处理汽车遮挡的技术:我们根据mABMs的检测结果粗略地重建汽车3d长方体模型,然后估计重叠系数来分离遮挡的汽车。真实图像的实验结果表明,该方法可以有效地检测严重遮挡下的车辆。

The research of reversible pop-up Hood for pedestrian protection 可翻转式行人保护罩的研究
David Xu, Xichan Zhu, Q. Miao, Zhixiong Ma, Bin Wu
Pedestrian protection has become one of the key points of vehicle design, and the requirements of pedestrian head protection are especially difficult to fulfill. Hood lifting is a new technology which can improve the pedestrian head protection performance of vehicles by lifting up the hood before pedestrian head impact with vehicle, but most of the pop-up hoods available are irreversible, causing high maintenance costs. Therefore a new reversible pop-up hood was designed in this paper. First of all the FE model of the frontal body of the researched car was built and validated with test carried out according to the requirements of Directive 2003/102/EC phase I. Then the simulation analysis of Euro-NCAP head assessment was performed, finding that the head protection performance of the hood areas near windscreen and A-pillars are very poor, structural redesign itself can't improve the score of head protection of those areas efficiently. Therefore a new pop-up hood was designed, which can be lifted upwards and backwards about 0.4 second before the collision between pedestrian and car, to increase the free space beneath the hood and cover the bottom areas of the windscreen and A-pillar. This system also can be reset if the detection system makes false alarms to cut maintenance costs. Simulation results showed that this pop-up hood can efficiently improve the pedestrian head protection performance of the researched car, in accordance with the requirements of Directive 2003/102/EC and Euro-NCAP.
行人保护已成为车辆设计的重点之一,而行人头部保护的要求尤其难以满足。引擎盖升降是一项在行人头部与车辆碰撞之前将引擎盖提起来提高车辆对行人头部保护性能的新技术,但现有的弹出式引擎盖大多是不可逆的,维修成本高。为此,本文设计了一种新的可逆式弹出式引擎盖。首先根据2003/102/EC指令第1阶段的要求建立了所研究汽车的前车身有限元模型并进行了试验验证,然后进行了Euro-NCAP头部评估的仿真分析,发现靠近挡风玻璃和a柱的引擎盖区域的头部防护性能很差,结构重新设计本身并不能有效地提高这些区域的头部防护得分。因此,设计了一种新的弹出式引擎盖,可以在行人与汽车碰撞前0.4秒左右向上和向后抬起,以增加引擎盖下方的自由空间,并覆盖挡风玻璃和a柱的底部区域。如果检测系统发出假警报,该系统也可以复位,以降低维护成本。仿真结果表明,该弹出式引擎盖能有效提高所研究汽车的行人头部保护性能,符合2003/102/EC指令和Euro-NCAP的要求。

Scalable parallel simulator for vehicular collision detection 用于车辆碰撞检测的可扩展并行模拟器
Ilan Grinberg, Y. Wiseman
Several simulations for parallel vehicular collision detection have been suggested during the last years. Such a simulator saves the need to physically cause the collision. The algorithms usually greatly depend on the parallel infrastructure and this dependency causes in many times non-scalability performance. The dependency also harms the portability of the simulation. This paper suggests a scalable and portable parallel algorithm for a vehicular collision detection simulation that fits both clusters and MPI machines. This paper explains how this Simulator was designed and implemented in a large transportation company.
在过去的几年里,人们提出了几种平行车辆碰撞检测的仿真方法。这样的模拟器节省了物理上引起碰撞的需要。算法通常在很大程度上依赖于并行基础结构,这种依赖导致很多时候性能不可伸缩性。依赖性还损害了模拟的可移植性。本文提出了一种适用于集群和MPI机器的可扩展、可移植的车辆碰撞检测仿真并行算法。本文阐述了该模拟器在某大型运输公司的设计与实现。

K. Leu, Yung-Yuan Chen, C. Wey, Jwu-E Chen
The increasing importance of FlexRay systems in automotive domain inspires unceasing relative researches. One primary issue among researches is to verify the robustness of FlexRay systems either from protocol aspect or from system design aspect. However, research rarely addresses the issue that network topology selection will also cause difference in robustness. In this paper, we will illustrate how to model the robustness under various network topology adoptions by a well-known technology, fault tree analysis (FTA). Quantitative and qualitative analysis results can show the potential and suitability of FTA for modeling FlexRay systems' robustness.

Development tools for active safety systems: Prescan and VeHIL 主动安全系统开发工具:Prescan和VeHIL
F. Hendriks, M. Tideman, R. Pelders, R. Bours, X. Liu
Active safety systems are increasingly becoming available in trucks and passenger vehicles. Developments in the field of active safety are shifting from increasing driver comfort towards increasing occupant safety. Furthermore, this shift is seen within active safety systems: safety functions are added to existing comfort systems, rather than adding new safety systems to the vehicle. Comfort systems such as cruise control are extended via ACC to pre-crash braking systems. Testing of active safety systems must follow these developments. Whereas standardized test programs are available for passive safety systems, such test programs are hardly available yet for active safety systems. Furthermore, test programs for passive safety systems consist of only a handful of scenarios. Test programs for active safety systems, however, should consist of much more scenarios, as those systems should function well in many different situations. It is not feasible to assess the intelligent vehicle safety (IVS) system's performance in all these scenarios by means of test-track testing. To speed up the introduction of active safety systems, there is a need for an efficient standardized test program, including alternatives to test track testing. This paper describes the vision of TNO Automotive on the developments that are expected in the field of development and evaluation of active safety systems and it explains the need for an efficient and complete test program for IVS systems, consisting of simulations, hardware-in-the-loop simulations and test track testing.
主动安全系统越来越多地应用于卡车和乘用车。主动安全领域的发展正从提高驾驶员舒适度转向提高乘员安全性。此外,这种转变体现在主动安全系统中:安全功能被添加到现有的舒适系统中,而不是在车辆上添加新的安全系统。巡航控制等舒适系统通过ACC扩展到碰撞前制动系统。主动安全系统的测试必须遵循这些发展。虽然标准化测试程序可用于被动安全系统,但这种测试程序很难用于主动安全系统。此外,被动安全系统的测试程序只包含少数几个场景。然而,主动安全系统的测试程序应该包含更多的场景,因为这些系统应该在许多不同的情况下运行良好。在所有这些场景下,通过测试轨迹测试来评估智能车辆安全系统的性能是不可行的。为了加快主动安全系统的引入,需要一个有效的标准化测试程序,包括测试轨道测试的替代方案。本文描述了TNO Automotive在主动安全系统开发和评估领域的发展愿景,并解释了对IVS系统的有效和完整的测试程序的需求,包括仿真,硬件在环仿真和测试轨道测试。

Extending land navigation applications to support off road based on elevation and land characteristics 扩展陆地导航应用,以支持基于海拔和土地特征的越野
G. Selim, Ahmed Ismail Abdel Sabour
Most used software tools for land navigation don't have the ability to calculate optimal path outside road network. They show direct Euclidian path from start and goal to nearest road facility. In this paper, we propose an extension for software tools of land navigation to calculate optimal Least Cost Path (LCP) outside road networks using land characteristics and/or digital elevation data (DEM). This extension can be used in off-road navigation by specifying a goal location over map and getting start location from Global Positioning Systems (GPS). Then display the path over a map, current location, and navigation aids. The experimental results of our emulated land navigation system shows that it can be used in real off- road navigation.

Active safety diagnosis of brake-by-wire systems with unscented Kalman filter 基于无气味卡尔曼滤波的线控制动系统主动安全诊断
Wei-Song Lin, T. Tang
Electric vehicle with brake-by-wire system may perform active safety control while keeping the vehicle lithe and nimble. Active safety diagnosis of the brake-by-wire system may find braking component that is on the brink of ceasing effectiveness. The diagnosis relies on using a diagnostic observer to continuously monitor the disk-pad friction coefficient and the tire forces; safety flaw is announced if any observed value violates the safety requirements. This paper presents a design of the diagnostic observer with the unscented Kalman filter. The unscented Kalman filter enforces the parameter observations more adaptive for dealing with the nonlinear vehicle-tire dynamics. The diagnostic observer is verified for active safety diagnosis of a vehicle under many operation conditions; simulation results show that the design is efficacious.

Event sequence reconstruction in automated guided vehicle systems 自动导向车辆系统中的事件序列重建
Yizhi Qu, Lingxi Li, Yaobin Chen, Yaping Dai
This paper addresses the problem of reconstructing the event sequences in an automated guided vehicle system (AGVs) that is modeled as a Petri net. We assume that every location of vehicles in the AGVs (i.e., each place in the net) is equipped with a sensor that is able to detect the presence of vehicles. Furthermore, the observation of each sensor is asynchronous and each sensor only knows the ordering of its local observations due to the lack of global time. Our goal is to reconstruct the movement trajectories (transition firing sequences) of vehicles based on these asynchronous sensor observations. We develop an algorithm that is able to obtain these event sequences that are consistent with both sensor observations and the Petri net structure.
本文研究了用Petri网建模的自动导引车辆系统(agv)中事件序列的重构问题。我们假设agv中车辆的每个位置(即网络中的每个位置)都配备了能够检测车辆存在的传感器。此外,每个传感器的观测是异步的,由于缺乏全局时间,每个传感器只知道其局部观测的排序。我们的目标是基于这些异步传感器观测重建车辆的运动轨迹(过渡射击序列)。我们开发了一种算法,能够获得与传感器观测和Petri网结构一致的事件序列。

We assume that every location of vehicles in the AGVs (i.e., each place in the net) is equipped with a sensor that is able to detect the presence of vehicles. Furthermore, the observation of each sensor is asynchronous and each sensor only knows the ordering of its local observations due to the lack of global time. Our goal is to reconstruct the movement trajectories (transition firing sequences) of vehicles based on these asynchronous sensor observations. We develop an algorithm that is able to obtain these event sequences that are consistent with both sensor observations and the Petri net structure.","PeriodicalId":416036,"journal":{"name":"Proceedings of 2010 IEEE International Conference on Vehicular Electronics and Safety","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115437949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
