Patent number: 10640036Abstract: A communications control unit and external sensors acquire external environment information including information on the vicinity of a vehicle. An autonomous driving control ECU calculates a warning level relating to continuing autonomous driving on the basis of the vicinity information. A speech generation section generates speech information on the basis of the external environment information acquired by the communications control unit and the external sensors. A control section controls speaking equipment so as to change at least one of speech information to be announced by the speaking equipment, a frequency of announcement of the speech information, and vocalization, in accordance with the warning level calculated by the autonomous driving control ECU. When autonomous driving is continuing, the control section controls the speaking equipment so as to repeat announcements of the speech information.Type: GrantFiled: July 27, 2017Date of Patent: May 5, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaya Watanabe, Yoshinori Yamada, Chikashi Takeichi, Satoshi Arikura
