The autonomous vehicle is called RobuCar which is constituted by four independently driven wheels and two independently adjustable steering angles. Firstly, the authors develop longitudinal and lateral controllers for the vehicles operating normally. The objective is to follow a reference trajectory and to maintain safe spacing between vehicles. Secondly, the authors develop some strategies based on fault detection and isolation results in order to reconfigure the convoy of vehicles in presence of faults. Three categories have been considered: sensor or actuator fault which has not altered the trajectory; fault that affects the velocity or disturbs the trajectory; faults that make impossible for the vehicle to continue its mission. Simulation results are given at the end to show the efficiency of the approach.","PeriodicalId":322982,"journal":{"name":"Journal of Asian Electric Vehicles","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130092889","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 use of lithium ion battery had little voltage changes and enabled the smooth running compared with contact-wire type railcar. On one charge, it was also found from the running test that the railcar could run for about 40 km and the mileage improved 9 %.

Activity of an electrocardiogram (ECG) may be associated with the physical load of moving for people with mobility handicaps in use of wheelchairs. The aim of this study is to investigate the relationship of ECG activity with the physical load of electric and manual wheelchair users and visually impaired people when crossing a main road with difficult access to high sidewalks. Eight voluntary students participated in the study. R-R interval times of heart beats were continuously recorded for each session of manual/electric wheelchairs and visually impaired. Experimental road conditions included places where there was a 0 cm to 10 cm drop or a steep step at both sides of the road. It is concluded that electric wheelchairs can provide stable driving for their users under conditions where there are differences in height between sidewalk and road, which are common obstacles for the users of wheelchairs. Furthermore, the influences of the sidewalk curb on heart beats when changing the method of transportation with difference conditions of curb are discussed. In addition, it was found that there are different influences of the curb heights on wheelchair users and visually impaired people.","PeriodicalId":322982,"journal":{"name":"Journal of Asian Electric Vehicles","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125300155","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}

They are also used as a cheap way to store energy for electric-powered vehicles, EV's. Life prolongation of these batteries is an important issue for resource conservation and the reduction of environmental contamination caused by discarded batteries. For this purpose, an organic battery activator named ITE (International Technology Exchange) activator has been exploited since 1996. This additive is an organic battery activator. The results of high-precision bench-tests, which are conducted in order to find an optimization of the activator's density, are described in this paper. The test results show that the best life-prolongation is achieved when an activator of 5Wt% with 10cc/cell is added for a starting battery of engine, 28Ah (10hrs).","PeriodicalId":322982,"journal":{"name":"Journal of Asian Electric Vehicles","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124417457","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 report, the designing and manufacturing activity using small-sized electric vehicles is described. As well as the design, the manufacturing aspect is also considered to be of great importance for mechanical engineers. As a capstone learning course, two teams in our laboratory tried to design and manufacture. One is a hand-made small-sized electric automobile, and the other a hand-made electric motorcycle. The former is suitably gentle for elderly drivers, and is the revised one from the vehicle made last year.","PeriodicalId":322982,"journal":{"name":"Journal of Asian Electric Vehicles","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115744947","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 battery itself has an internal resistance that makes it difficult to control the charging and discharging process because the capacity of the battery is estimated by the potential difference between the two electrodes of the battery, named external voltage. When the effective internal resistance of the battery is increased due to the deterioration, the external voltage is too high to stop charging even though the battery has not stored a sufficient amount of energy. This paper introduces a new method of charging and discharging and the resulted effectiveness of this method to the lead acid battery life prolongation is shown.","PeriodicalId":322982,"journal":{"name":"Journal of Asian Electric Vehicles","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115175692","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}
