Abstract

A display device for a vehicle includes a collision predictor, a display member, and a display controller. The collision predictor detects a moving body sideward of a course of the vehicle and predicts collision of the vehicle with the moving body detected. The display member provides display of an image or display of a mark, for view of a driver seated on a driver'"'"'s seat of the vehicle. The image or the mark corresponds to the moving body. The display controller performs a control of the display member. The display controller changes the display of the image or the display of the mark more significantly than a motion of the moving body as actually seen from the driver'"'"'s seat, on a condition that the collision predictor predicts the collision.

classify moving bodies into a moving body on the driver'"'"'s-seat side and a moving body on the navigator'"'"'s-seat side;

display images of the moving body on the driver'"'"'s-seat side on the first display member; and

display images of the moving body on the navigator'"'"'s-seat side on the second display member, and

wherein the one or both of the second image and the second mark are displayed in the display apparatus so that at least one of following conditions is further implemented;

an amount where the second image displayed on the second display member is changed is smaller than an amount where the second image displayed on the first display member is changed; and

an amount where the second mark displayed on the second display member is changed is smaller than an amount where the second mark displayed on the first display member is changed.

2. The display device for the vehicle according to claim 1, wherein the one or both of the second image and the second mark are displayed in the display apparatus so that the one or both of the second image and the second mark change, with a faster movement than a motion of the moving body as actually seen from the driver, the motion of the moving body including crossing the travel direction.

3. The display device for the vehicle according to claim 2, wherein the one or more computers allow one or both of an amount of a change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark to differ between a first case and a second case, the first case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a right side with respect to the driver'"'"'s seat in the traveling direction, and the second case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a left side with respect to the driver'"'"'s seat in the traveling direction.

4. The display device for the vehicle according to claim 2, wherein one or both of an amount of a change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark in a first case are larger than an amount of the change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark in a second case, the first case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a driver'"'"'s seat side on which the driver'"'"'s seat is disposed, and the second case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a navigator'"'"'s seat side opposite to the driver'"'"'s-seat side.

5. The display device for the vehicle according to claim 1, wherein the one or both of the second image and the second mark are displayed in the display apparatus so that the one or both of the second image and the second mark change, with a faster movement than a motion of the moving body as actually seen from the driver, the motion of the moving body including approaching the vehicle.

6. The display device for the vehicle according to claim 5, wherein the one or more computers allow one or both of an amount of a change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark to differ between a first case and a second case, the first case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a right side with respect to the driver'"'"'s seat in the traveling direction, and the second case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a left side with respect to the driver'"'"'s seat in the traveling direction.

7. The display device for the vehicle according to claim 5, wherein one or both of an amount of a change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark in a first case are larger than an amount of the change in the display apparatus of the second image and an amount of the change in the display apparatus of the second mark in a second case, the first case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a driver'"'"'s seat side on which the driver'"'"'s seat is disposed, and the second case being a case where the moving body relevant to the one or both of the first image and the first mark are positioned on a navigator'"'"'s seat side opposite to the driver'"'"'s-seat side.
