  • Publication number: 20200398862
    Abstract: In a vehicle warning system, the line-of-sight detection unit detects the line of sight of a driver operating the vehicle. The line-of-sight fixedness determination device determines the line-of-sight fixedness condition, in other words, how much the line of sight of the driver that is detected by the line-of-sight detection unit, is fixed. The danger-level determination device determines the driving conditions. The warning-level determination unit determines the warning level, based on the line-of-sight fixedness condition that is determined by the line-of-sight fixedness determination device, and the driving conditions that is determined by the danger-level determination device. The alerting unit alerts the driver based on the warning level that is determined by the warning-level determination unit.

  • Publication number: 20200283013
    Abstract: A passenger support system includes a speaker, cameras, a vibrator, a seat switch, and a control device. The control device issues destination approach information by the speaker before the vehicle arrives at the destination based on results from comparing the current location information of the vehicle with the destination information of passenger. After issuing the destination approach information, the control device identifies the seat position based on the images captured by the cameras and performs awakening action by the vibrator at the seat corresponding to the specified seat position. The control device stops the awakening action by the vibrator when a stop operation is received from the seat switch.

  • Publication number: 20200143189
    Abstract: A monitoring system includes a pair of a right-side light source and a left-side light source for irradiating the face of an occupant with light, the pair being disposed in the horizontal direction with a camera interposed therebetween when the camera is viewed from the vertical direction. The right-side light source and the left-side light source are alternately turned on for each imaging by the camera. The camera obtains each of a first face image that is imaged in accordance with lighting of the right-side light source and a second face image that is imaged in accordance with lighting of the left-side light source. A controller determines the visual line state based on the first face image, and the second face image that is obtained at a time point proximate to the time point at which the first face image is obtained.

  • Publication number: 20190276047
    Abstract: An object of the present invention is to provide an alertness maintaining device useful for suppressing variation of an alertness of a driver and for maintaining the alertness at a comparatively high level. The alertness maintaining device includes a driver state monitoring section that detects at least one of an actual alertness of a driver and predicted change of the alertness; a voice output section that applies, to the driver, stimulus information; and an interaction control section that changes an output content of the stimulus information output section in accordance with a level of the alertness based on an output of the driver state monitoring section. The strength of the stimulus is changed in accordance with the level of the alertness. When a simple running state is detected, a stimulus for maintaining the alertness is applied. An interaction scenario according with preference of the driver is selectively used.

  • Publication number: 20190124239
    Abstract: The present invention provides an on-vehicle photographing device. A monitoring camera is installed inside a common area that is made common to the display area of an indicator display section for displaying the states of the vehicle, such as direction indication, as viewed from the position corresponding to the viewpoint of the driver of the vehicle. Since the monitoring camera is assimilated with the area of the indicator display section and becomes less conspicuous, the driver is deluded and unaware of the existence of the monitoring camera. The monitoring camera and the indicator display section are entirely covered integrally or continuously with a film or the like, and this entire structure is configured so as to be recognized by the driver as a common indicator area. Infrared illumination sections are provided and the monitoring camera performs photographing using the light having wavelengths in the infrared light wavelength region.
