However, in some cases, straight-ahead stability differs between two vehicles with similar low C_L. On the other hand, a moving vehicle shows complex behaviors due to unsteady aerodynamic forces caused by unsteady flow around the vehicle and unsteady vibration induced by undulated road. As C_L simply indicates time-average, it could be considered that C_L may not fully describe such complex vehicle behaviors during high speed driving. Therefore. in this study, an attempt was made to clarify the relationship between unsteady flow around a moving vehicle and straight-ahead stability by investigating aerodynamic forces generated from unsteady flow. As a result, it is clarified in wind tunnel experiments and on-road driving experiments that vehicle straight-ahead stability is greatly influenced by a distinctive unsteady vortex structure above the trunk deck."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282681237622017","@type":"Researcher","foaf:name":[{"@language":"ja","@value":"農沢 隆秀"},{"@language":"en","@value":"NOUZAWA Takahide"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Mazda Motor Corporation, Vehicle Testing & Research Department"},{"@language":"ja","@value":"マツダ(株)車両実験研究部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205883244162","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000006668001"}],"foaf:name":[{"@language":"ja","@value":"岡田 義浩"},{"@language":"en","@value":"OKADA Yoshihiro"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"マツダ(株)車両実験研究部空力実研グループ"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205883244160","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000006668002"}],"foaf:name":[{"@language":"ja","@value":"岡本 哲"},{"@language":"en","@value":"OKAMOTO Satoshi"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"マツダ(株)車両実験研究部空力実研グループ"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205882631299","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000006330616"}],"foaf:name":[{"@language":"ja","@value":"中村 貴樹"},{"@language":"en","@value":"NAKAMURA Takaki"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"マツダ(株)車両実験研究部空力実研グループ"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"03875016"},{"@type":"EISSN","@value":"18848346"},{"@type":"NDL_BIB_ID","@value":"000000031919"},{"@type":"ISSN","@value":"03875016"},{"@type":"LISSN","@value":"03875016"},{"@type":"NCID","@value":"AN00187441"}],"prism:publicationName":[{"@language":"en","@value":"TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B"},{"@language":"ja","@value":"日本機械学会論文集Ｂ編"},{"@language":"ja","@value":"日本機械学会論文集 B編"},{"@language":"en","@value":"Trans.JSME, B"},{"@language":"en","@value":"Trans.JSME, Ser.B"},{"@language":"en","@value":"Trans.JSME(B)"},{"@language":"en","@value":"Trans.JSME B"},{"@language":"en","@value":"Trans.JSME Ser.B"},{"@language":"en","@value":"Transactions of the Japan Society of Mechanical Engeneers,Series B"},{"@language":"ja","@value":"日機論（Ｂ編）"},{"@language":"ja","@value":"機論Ｂ編"},{"@language":"ja","@value":"機論（Ｂ）"},{"@language":"ja","@value":"機論（Ｂ編）"},{"@language":"ja","@value":"日機論Ｂ編"},{"@language":"ja","@value":"日本機械学会論文集Ｂ編"},{"@language":"ja","@value":"日本機械学会論文集（Ｂ編）"},{"@language":"ja","@value":"日機論（Ｂ）"},{"@language":"ja","@value":"日本機械学会論文集（Ｂ）"},{"@language":"en","@value":"Transactions of the Japan Society of Mechanical Engineers.
