  • Patent number: 11264000
    Abstract: A display control device controls display of a virtual image which is superimposed on foreground of a vehicle by projection of a display light image from an optical unit to a projection area. The display control device sets a projection position of the display light image which is projected in the projection area on the basis of a relative position of a superimposition object on which the virtual image is superimposed, obtains a measurement information from one vehicle height sensor measuring a displacement in a vertical direction occurring in the vehicle, obtains a gradient information indicating a gradient of a road on which the vehicle travels on the basis of three-dimensional map data, and corrects the projection position of the display light image on the basis of the measurement information and the gradient information.

  • Patent number: 11220274
    Abstract: A vehicle display control device controls display performed by a head-up display for a vehicle. The head-up display is configured to project an image on a projection member to cause a virtual image to be displayed in superimposed relation on a front view of the vehicle. The vehicle display control device determines a host vehicle situation as a road structure of a road on which a host vehicle is running, and controls to limit or not to limit a superimposed display of the virtual image with respect to a target object on which the virtual image is to be displayed in superimposed relation according to the host vehicle situation determined.

  • Publication number: 20210031776
    Abstract: A display control unit controls a virtual image display device that superimposes a virtual image on a foreground of an occupant of the vehicle. The display control unit acquires posture information indicating a change in posture of the vehicle based on a signal of a posture sensor attached to the vehicle. The display control unit acquires driving force information indicating a state of a driving force acting on the vehicle. The display control unit determines that the vehicle is traveling on a rough road when the change in posture indicated by the posture information exceeds a threshold value in a state where the driving force indicated by the driving force information is stable.

  • Patent number: 10569649
    Abstract: An in-vehicle control apparatus performs a hazard avoidance process. The in-vehicle control apparatus includes an anomaly determination section, an alarm control section, and a hazard avoidance control section. The anomaly determination section determines whether a driver is under driving inability state during travel of the vehicle, based on information on monitoring of state of the driver. The alarm control section activates an alarm annunciator to issue an alarm outwardly from the vehicle when the driver is determined to be under driving inability state. After the alarm annunciator starts the alarm, the hazard avoidance control section fails to perform the hazard avoidance process when the alarm is stopped by a manipulation of the driver and performs the hazard avoidance process when a specified time elapses under state where the alarm is not stopped since the starting of the alarm.
