  • Patent number: 11597410
    Abstract: An automatic driving proposal device or an automatic driving proposal method is used for a vehicle that selects either a state of an automatic driving or a state of a manual driving by an occupant. The automatic driving proposal device or the automatic driving proposal method performs a driving change request to the occupant in the state of the automatic driving, determines whether the automatic driving is possible in the state of the manual driving, calculates a calculation value corresponding to a distance or a prediction time or calculates a change index, and proposes the automatic driving to the occupant on a necessary condition of determining that the automatic driving is possible and also determining that the calculation value is higher than a threshold value or determining that the change index is lower than a threshold value.

  • 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.

  • Publication number: 20190001994
    Abstract: In a vehicle control apparatus which controls movement of the own vehicle, the control unit obtains data of surroundings of the own vehicle. Then, according to the data of the surroundings, the control unit conducts vehicle control including acceleration/deceleration control representing control related to acceleration/deceleration of the own vehicle, and steering control representing control related to steering of the own vehicle. Upon input of a stop command indicating stop of the vehicle control, a first stop section stops first control which is either of the acceleration/deceleration control and the steering control. Then, a second stop section stops a second control, which is the other of the acceleration/deceleration control and the steering control, at a timing different from the timing to stop the first control (S310).

  • Publication number: 20180354517
    Abstract: A driving assistance apparatus includes an operation determiner section and a change approver section. The operation determiner section determines whether a driver of a vehicle executes a safety confirming operation against lane change based on information from a sensor used to detect a state of a driver. The change approver section approves an automated lane change by a lane changer section. Herein, the change approver section disapproves an automated lane change by the lane changer section when the operation determiner section determines that the driver fails to execute a safety confirming operation against lane change.
