In order to ensure safety, positioning algorithms should implement fault detection and fallback strategies. While many strategies stop the vehicle once a failure is detected, in this work a new framework is proposed that includes an improved reconfiguration module to evaluate the failure scenario and offer alternative positioning strategies, allowing continued driving in degraded mode until a critical failure is detected. Furthermore, as many failures in sensors can be temporary, such as GPS signal interruption, the proposed approach allows the return to a non-fault state while resetting the alternative algorithms used in the temporary failure scenario. The proposed localization framework is validated in a series of experiments carried out in a simulation environment. Results demonstrate proper localization for the driving task even in the presence of sensor failure, only stopping the vehicle when a fully degraded state is achieved. Moreover, reconfiguration strategies have proven to consistently reset the accumulated drift of the alternative positioning algorithms, improving the overall performance and bounding the mean error.<\/jats:p>","DOI":"10.3390\/s22072595","type":"journal-article","created":{"date-parts":[[2022,3,29]],"date-time":"2022-03-29T21:45:51Z","timestamp":1648590351000},"page":"2595","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Reconfigurable Framework for Vehicle Localization in Urban Areas"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9493-6832","authenticated-orcid":false,"given":"Kerman","family":"Viana","sequence":"first","affiliation":[{"name":"Faculty of Engineering in Bilbao, University of the Basque Country UPV\/EHU, 48013 Bilbao, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6049-2308","authenticated-orcid":false,"given":"Asier","family":"Zubizarreta","sequence":"additional","affiliation":[{"name":"Faculty of Engineering in Bilbao, University of the Basque Country UPV\/EHU, 48013 Bilbao, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3364-5003","authenticated-orcid":false,"given":"Mikel","family":"Diez","sequence":"additional","affiliation":[{"name":"Faculty of Engineering in Bilbao, University of the Basque Country UPV\/EHU, 48013 Bilbao, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,28]]},"reference":[{"key":"ref_1","unstructured":"Society of Automotive Engineers (SAE) (2018).
