In this paper, a multi-sensor target tracking system that combines data from a Frequency-Modulated Continuous Wave (FMCW) radar, multiple Short-Range Radars (SRR), a camera-based object detection system and vehicular dynamic sensors is described. Each object sensor individually measures the range, range rate and azimuth angle information of all objects within the observation region. The proposed system 1 groups objects from different sensors in overlapped observation region; 2 tracks an object across different sensor field of views; 3 reports the Cartesian coordinates of objects with improved accuracy and reduced rates of false detection and missed detection. The proposed target tracking system was implemented in a retrofitted vehicle. Only about two-percent CPU usage is needed for an 800 MHz embedded processor.

A bidirectional interaction is designed by deliberative candidates negotiating with the feedback on reactive evaluation. The deliberative module constructs a multilayer state lattice with switching control sets. Furthermore, a heuristic multitask-parallel algorithm efficiently generates desirable paths. The reactive module designs a hierarchical structure to integrate reaction optimisation and situation-dependent adjustment. Based on manifold correlations, piecewise criteria rather than a single function are proposed to cater for different stages of planning. Extensive experiments verify the efficacy, reliability and robustness of the approach in complex environments.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"11 1","pages":"334"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2013.056613","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66820614","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}

Firstly, linearisation control of steering sensitivity enables the driver to recognize vehicle and road state via reaction torque of a steering wheel. It is power assist based on human kinesthetic sense by electric power steering. Secondly, linearisation control of vehicle yaw motion with in-wheel motors. Humans feel rotational motion by semicircular canal and vision. A driver controls yaw motion with the steering wheel. Therefore, this control increases operational performance for the vehicle.

The concept where battery driven vehicles such as PHEVs provide ancillary service to the grid is commonly referred to as Vehicle to Grid (V2G). As each PHEV has a limited capacity, it is necessary to have a control system that aggregates a large number of vehicles. This paper investigates what is required in order to design such a system. The result is presented as reference architectures and contains propositions of important components, processes and information needs. It is shown that a PHEV can provide control power in two different ways that in turn generate several different system concepts. A mathematical model is presented that allows comparison between the different solutions.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"11 1","pages":"205-228"},"PeriodicalIF":0.0,"publicationDate":"2013-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2013.053780","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66821016","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}

Huang as a new class of learning algorithm for Single-Hidden Layer Feedforward Neural Networks (SLFNs), is extremely fast and accurate, and has better generalisation performance than the traditional gradient-based training methods. To implement Field-Oriented Control (FOC) in PMSMs, the stator magnetic field is always kept 90 degrees ahead of the rotor. This requires rotor position information all the time. This information is accurately obtained with an ELM-based observer without the position sensor for PMSMs, and hence, the cost of the system is reduced, while the problems associated with the sensors are minimised.","PeriodicalId":39322,"journal":{"name":"International Journal of Vehicle Autonomous Systems","volume":"32 1","pages":"190"},"PeriodicalIF":0.0,"publicationDate":"2013-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVAS.2013.053779","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66820998","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}

First, by comparing with a conventional array, the Halbach PM array is evaluated for the fault-tolerant PM motor. Second, by optimising the stator tooth shape, the short-circuit current is limited. Third, by doubling the current of the healthy phase, a remedial control strategy for the open-circuit fault is proposed.
