Publication number: 20230081020Abstract: A driving assistance device 1 is provided with: three or more detection units 5a to 5d which are configured to detect a likely-to-be-dozing state in which likelihood that a driver of a vehicle is dozing is high by different indices and at prescribed intervals; a state determination unit 34 which determines that the driver is in a dozing state when the likely-to-be-dozing state is detected by at least two of the detection units; and a warning control unit 36 which causes a warning device 6 to issue a warning when the state determination unit 34 determines that the driver is in the dozing state.Type: ApplicationFiled: February 15, 2021Publication date: March 16, 2023Inventors: Mayumi IWAO, Kazuhiko YAMAGUCHI, Yoshimune YAMAGISHI

Patent number: 11443534Abstract: In this vehicular monitoring device, an imaging unit 2 captures an image of the driver of a vehicle. A driving state measurement unit 70 analyzes the image captured by the imaging unit 2 and measures a plurality of driving states including the eye opening degree of the driver. A travel state determination unit 71 determines the travel state of the vehicle. An alarm determination unit 72 uses the driving states and the travel state as a basis to determine whether to activate an alarm device 5. When a statistical amount calculated from time series data for the eye opening degree acquired from the driving state measurement unit 70 is outside of a predetermined normal determination reference range, the driving states other than the eye opening degree are normal, and the travel state is determined to be normal, the alarm determination unit 72 causes the driving state measurement unit 70 to perform eye opening degree detection processing again.Type: GrantFiled: September 20, 2019Date of Patent: September 13, 2022Assignee: ISUZU MOTORS LIMITEDInventors: Shigeru Takinami, Kazuhiko Yamaguchi, Mayumi Iwao

Patent number: 11267478Abstract: An imaging unit 2 captures an image of a driver of a vehicle. A driving state measurement unit 70 analyzes the image captured by the imaging unit 2 and measures a plurality of driving states including the driver's face orientation angle. A traveling state determination unit 71 determines the traveling state of the vehicle. An alarm determination unit 72 determines whether to activate an alarm device 5 on the basis of the driving states and the traveling state. When the face orientation angle acquired from the driving state measurement unit 70 is out of a normal determination reference range, and it is determined that the driving states other than the face orientation angle are normal and the traveling state is also normal, the alarm determination unit 72 causes the driving state measurement unit 70 to re-execute the face orientation angle detection process.Type: GrantFiled: September 19, 2019Date of Patent: March 8, 2022Assignee: ISUZU MOTORS LIMITEDInventors: Kazuhiko Yamaguchi, Shigeru Takinami, Mayumi Iwao

Publication number: 20190059791Abstract: A motion estimation system includes a head motion detection unit, a mobile body motion detection unit, and a movement estimation unit. The head motion detection unit is worn on an occupant in a mobile body, and detects a motion of a head of the occupant. The mobile body motion detection unit detects a motion of the mobile body. The movement estimation unit obtains the motion of the head of the occupant and the motion of the mobile body, and estimates a movement of the head of the occupant made by the occupant according to a difference between the motion of the head of the occupant and the motion of the mobile body.Type: ApplicationFiled: September 6, 2016Publication date: February 28, 2019Applicants: DENSO CORPORATION, ISUZU MOTORS LIMITEDInventors: Tetsushi NORO, Shinji NIWA, Tadashi KAMADA, Yuuki MORI, Hirokazu OOYABU, Mayumi IWAO
