Patent number: 10336270Abstract: A vehicle and a manufacturing method thereof is provided in which separation of positively charged airflow from a positively charged surface of a vehicle body can be prevented. A vehicle body is insulated from a road surface, and positive static charges accumulate on the vehicle body during propulsion. The vehicle comprises a self-discharge device that is adapted to decrease a positive potential of at least any one of specific points at which positively charged airflow flowing along a vehicle surface deviates therefrom, during propulsion of the vehicle, by discharging static electricity to produce negative ions according to the positive potential of the specific point.Type: GrantFiled: August 29, 2014Date of Patent: July 2, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koshi Yamada, Toshio Tanahashi, Hisashi Yabuki, Kazuhiko Omasa, Yoji Kanehara, Nagataka Sassa, Naohiko Saito, Narito Fujii, Tsuyoshi Ohkita, Masaaki Morimoto, Kazuhiro Maeda, Taro Yamashita, Fumiatsu Suzuki
