Patent number: 10953794Abstract: A loudspeaker 14 outputs a warning sound for announcing the presence of a vehicle to the outside of the vehicle. A travel start detection unit 122 detects travel start of the vehicle. A sound pressure control unit 124 controls sound pressure of the warning sound to be output from the loudspeaker 14, depending on travel status of the vehicle. The sound pressure control unit 124 makes the loudspeaker 14 output the warning sound during stopping of the vehicle, and increases the sound pressure of the warning sound upon detection of travel start of the vehicle. This makes it possible to announce the travel start of a low-noise vehicle such as an electrically powered vehicle, without making the surroundings feel unnatural.Type: GrantFiled: February 21, 2018Date of Patent: March 23, 2021Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventor: Yoshihiro Kudo
