Patent number: 11981342Abstract: A display and voice output control system of a vehicle on which automated driving is performed includes a display device, a voice output device and a controller. The controller controls a notification of a recommended behavior by the display device and the voice output device. In the notification control, it is judged whether or not a notification condition of the recommended behavior is satisfied. If it is judged that the notification condition is satisfied, it is judged whether a notification relaxation condition of the recommended behavior is satisfied based on a status of a driver and a driving status of the vehicle. If it is judged that the notification relaxation conditions is satisfied, relaxation notification processing is executed. Otherwise, normal notification processing is executed. In the relaxation notification processing, an output status of the recommended behavior in the voice output device is controlled to an inactive state.Type: GrantFiled: June 28, 2021Date of Patent: May 14, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kiyotoshi Sekine, Takahiko Kuwabara, Ko Igarashi

Patent number: 11472429Abstract: The vehicle controller includes a processor configured to determine whether a behavior of a driver of the vehicle satisfies a predetermined enabling condition after execution of a function of automatically stopping the vehicle. The function is executed due to not satisfying a driver-related condition for continuing the automated driving control of the vehicle. The enabling condition relates to driving control of the vehicle and is not imposed before the execution of the function. The processor is further configured to perform the automated driving control of the vehicle only when the behavior of the driver satisfies the enabling condition.Type: GrantFiled: March 3, 2021Date of Patent: October 18, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kiyotoshi Sekine, Takahiko Kuwabara, Taiyo Uejima, Sho Mikuriya

Patent number: 11453334Abstract: A controller executes output state control in which an output status of a sound signal outputted from a sound source device and that of a blowing sound outputted from a sounding device are controlled based on driving environment information. In the output state control, it is judged whether or not an output condition of the blowing sound is satisfied based on the driving environment information. If it is judged that the output condition is satisfied, a mute signal is outputted to a sound source device to mute the output of the sound signal and also a blowing signal including mute information is outputted to the sounding device. The mute information includes information on a start timing to output the blowing sound. The start timing is variably set in accordance with an importance of the information provided to an occupant of the vehicle.Type: GrantFiled: June 23, 2021Date of Patent: September 27, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ko Igarashi, Naoki Nishimura, Takahiko Kuwabara
