Not all proposed face detection methods are suitable for direct hardware implementation. This paper proposes an improved skin-color based face detect method and outlines its transition from a software to hardware-based implementation. The hardware implementation of the face detect algorithm is examined by the FPGA (ALTERA CYCLONE EP1C6, field programmable gate arrays). Results show that it is robust to challenges of cluttered backgrounds, partial occlusion and varying illuminations. Its high detection and tracking performance makes it quite suitable for real-time applications, especially for power-limited devices, such as video surveillance systems for automated security, environment, transportation and health-care monitoring applications.","PeriodicalId":202772,"journal":{"name":"2007 IEEE International Conference on Vehicular Electronics and Safety","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130769427","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}

Most crops are cultivated in rows, hence enabling the development of a row-recognition system to accurately follow a row of plants without overrunning the crop. This paper presents a novel approach for extracting agricultural machine position from field images based on the look-ahead method and vanishing points. The proposed method facilitates the development of the guidance controller, simplifying the tuning and increasing the guidance system response and stability. The goal was to develop a quick position extraction method, based on the fact that by decreasing the image processing time increases the position data rate, providing fast response feedback control. Results demonstrated that the use of look- ahead method and vanishing point simplifies the guidance controller development and satisfactorily works with shadows, gaps, weeds and different light conditions.","PeriodicalId":202772,"journal":{"name":"2007 IEEE International Conference on Vehicular Electronics and Safety","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123177986","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}

But excessive regenerative torque may affect the anti-lock brake control. The paper presents a novel brake control strategy for electric vehicles which integrates the regenerative brake control and anti-lock brake control. The strategy is designed based on a novel idea called \"slip trial method\", where the regenerative brake torque and the friction brake torque are coordinated according to the slip of driving wheels. The strategy depends on neither road condition identification nor longitudinal braking force estimation. Simulation studies show that the strategy can obtain almost the optimal regenerative brake efficiency, and the tire slips are regulated in the stable region.","PeriodicalId":202772,"journal":{"name":"2007 IEEE International Conference on Vehicular Electronics and Safety","volume":"2006 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920285","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}

In this paper, we present a fingerprinting based location estimation technology in ZigBee network. The system uses the signal strength from several base stations rather than time or angle for determining the location of mobile station. Instead of modeling the complex attenuation of signal strength, the system models the probabilistic distribution in different geographical areas which we called fingerprinting. It combines the measured data and fingerprinting to determine the mobile station's location. The experiment results demonstrate the validity of location estimation in ZigBee network based on fingerprinting.","PeriodicalId":202772,"journal":{"name":"2007 IEEE International Conference on Vehicular Electronics and Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129099543","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}

The slip ratios are also accurately estimated in a new way to support this control process. Firstly in this control method, the fuzzy logic method is applied respectively to regulate the switching surface and the reaching law of DSMC with the estimated slip ratios, which are used to weaken the chattering and improve the convergence rate to some extent Furthermore the control structure of DSMC is designed to obtain the smooth torque outputs from all independent traction motors, which are implemented in the anti-skid control for EV in the end. The simulation experiments show that the method can greatly avoid the drawback of control chattering occurred in the classical sliding mode control.

In rail transportation fields, this has become more complex and the methods to ensure the correctness of train control system have been slow in development. The failure to meet time deadline can have serious or even fatal consequences. This paper presents a new method for performing this verification task. In the proposed method the real-time system is modeled by Timed Automata Network (TAN) and verified by model checking which explores the state space to determine whether the system satisfies a given specification. The case study of ATP (Automatic Train Protection) shows how the method can assist in designing more efficient and reliable real-time systems. Firstly, the state transitions and multi-tasks ATP onboard model will be modeled with Timed Automata Network (TAN) model, and then the time sequences of each task are expressed in UML Sequence Diagrams. Finally, the timing characteristics will be verified to meet the requirement by SMV model checker. A major conclusion of the survey is that formal methods, while still immature in some respects, can be used successfully to model and verify real-time concurrent systems.","PeriodicalId":202772,"journal":{"name":"2007 IEEE International Conference on Vehicular Electronics and Safety","volume":"364 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576502","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}
