The　driving　vibration　caused　by　the　pavement　roughness　is　an　important　factor　affecting　the　driving　comfort,　and　the　driving　vibration　is　speed-dependent,　so　there　are　some　deficiencies　in　the　method　of　reflecting　the　driving　feeling　only　by　the　pavement　roughness　index.　Small　smart　devices　represented　by　smartphone　can　detect　vibration　and　speed.　In　order　to　provide　a　new　reference　method　for　pavement　driving　comfort　evaluation,　Honda-CRV　and　smartphone　were　used　as　the　experimental　vehicle　and　data　collection　equipment.　Driving　experiments　were　carried　out　on　several　ordinary　asphalt　pavement　sections　with　different　smoothness,　and　the　driving　vibration　and　speed　data　were　obtained　by　experiment　phone.　Taking　the　vector　synthetic　vibration　acceleration　as　the　vibration　index,　a　new　index　for　pavement　driving　comfort　evaluation　-　comfort　rate　(CR)　was　put　forward　from　the　point　of　view　of　the　time　of　road　section　driving　vibration　process.　The　CRs　of　different　experiment　sections　were　calculated,　the　relationship　between　CR　and　riding　quality　index　(RQI)　was　analyzed,　the　feasibility　of　using　CR　as　the　evaluation　index　of　driving　comfort　was　discussed.　Finally,　according　to　the　CR　distribution　range　of　the　experimental　sections　and　the　meaning　of　CR,　the　CR　rating　method　for　driving　comfort　evaluation　was　proposed,　which　provided　a　new　way　to　evaluate　the　driving　comfort　with　driving　intelligent　perception　data.　©　2021　IEEE.
