  • Patent number: 11702091
    Abstract: A drive mode switch control device acquires operation information. The drive mode switch control device switches a drive state among at least an autonomous drive state, a manual drive state, and a coordination drive state. The operation detection unit detects a first operation and a second operation based on the operation information when the drive state is not in the manual drive state. The second operation is the drive operation different from the first operation and input after the input of the first operation. The drive mode switch control device switches the drive state from the autonomous drive state to the coordination drive state based on a detection determination of the first operation. The drive mode switch control device switches the drive state from the coordination drive state to the manual drive state based on a detection determination of the first operation.

  • Publication number: 20220144087
    Abstract: In a display control device for a head-up display mounted in a vehicle, when a lane keeping control function of driving a vehicle to travel in a traveling lane is terminated, a termination notification image to notify a driver of a termination of the lane keeping control function is generated and caused to be displayed by the head-up display. As another example, in a configuration where the operation of the lane keeping control function is continued even when one of a right road line and a left road line of the traveling lane is not detected, a continuation notification image to notify a driver of a continuation of the lane keeping control function is generated and caused to be displayed by the head-up display.

  • Publication number: 20220118983
    Abstract: A display control device is used for a vehicle having a function of performing a lane change control based on a driver's input to control a display on a head-up display. The display control device acquires route information of the vehicle, and displays a route guidance content providing a route guidance based on the route information to be superimposed on a road surface, and displays a lane change content indicating a control content of the lane change control to be superimposed on a road surface. When a display request to display one of the route guidance content and the lane change content is generated while the other is being displayed, the display control device displays the lane change content in preference to the route guidance content.

  • Publication number: 20220058998
    Abstract: In a display control device for a head-up display in a vehicle, a boundary information regarding a boundary of a travel lane recognized for driving control of the vehicle is acquired, and guidance information used for route guidance is acquired. When an estimated trajectory content indicating an estimated trajectory of the vehicle controlled based on the boundary information and a route guidance content providing guidance on a route at a predetermined point based on the guidance information are displayed together, the estimated trajectory content and the route guidance content are displayed in different modes from each other, or a display range of the estimated trajectory content is limited to a range not beyond a predetermined point for the route guidance. As another example, when the guidance information is acquired during display of the estimated trajectory content, the route guidance content is displayed while hiding the estimated trajectory content.

  • Publication number: 20220024314
    Abstract: In a display control for a head-up display of a vehicle, offset information is acquired from a lane keeping control unit that controls the vehicle to travel within a subject vehicle lane on which the vehicle travels. The offset information indicates an offset control to move a traveling position from a center portion of the subject vehicle lane to one of right and left sides. Based on the offset information, an offset content indicating fulfillment of the offset control is superimposedly displayed on a road surface in a foreground.

  • Publication number: 20220016980
    Abstract: In a display control device for a head-up display of a vehicle, a schedule notification content indicating a fulfillment schedule of a lane change is displayed on a road surface in a foreground in a superimposing manner. When the schedule notification content overreaches an angle of view, a non-superimposition content indicating the fulfillment schedule of the lane change independent of a superimposition target may be displayed, or the schedule notification content may be hidden. In a case where an arrow-shaped schedule notification content, having a tip portion indicating an adjacent lane as a destination of the lane change, is displayed in a superimposing manner on a road surface in the foreground, when the tip portion of the schedule notification content in a reference shape overreaches the angle of view, the schedule notification content may be transformed so that the tip portion is positioned within the angle of view.

  • Publication number: 20220018678
    Abstract: In a display control device for a head-up display of a vehicle, it is determined whether a lane change control unit is in a standby state waiting for a lane change of the vehicle. When it is determined that the lane change control unit is not in the standby state, a fulfillment notification content indicating an execution state of the lane change is displayed on a road surface in a foreground in a superimposing manner. When it is determined that the lane change control unit is in the standby state, a standby notification content in a mode different from the fulfillment notification content is displayed on the road surface of the foreground in a superimposing manner, or a standby notification content in a mode associated with the fulfillment notification content is displayed as a non-superimposition content independent of a superimposition target.

  • 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).
