Abstract

A driving assistance device according to an embodiment includes: a target setting unit configured to set a stop target; an acquisition unit configured to acquire a position of a vehicle; and an output information control unit configured to control a display unit to display a first image that instructs a driver to stop the vehicle in a first form when the vehicle is located within a region including the stop target and display the first image in a second form different from the first form when the vehicle is located outside the region.

First claim

The invention claimed is:

1. A driving assistance device, comprising:
a processor that
sets a stop target,
acquires a position of a vehicle, and
controls a display unit to display a first image and a second image on a screen, the first image that instructs a driver to stop the vehicle, is displayed in a first form when the vehicle is located within a region including the stop target, and is displayed in a second form different from the first form when the vehicle is located outside the region, the second image indicating a direction corresponding to a travel direction of the vehicle, wherein
the processor controls the display unit to dispose the first image with respect to the second image in the direction indicated by the second image, and
the second image is an indicator that points to the first image.

2. The driving assistance device according to claim 1 , wherein the second image changes in accordance with the position of the vehicle.

3. The driving assistance device according to claim 1 , wherein
the stop target comprises a first target and a second target that is provided in a middle of a path for guiding the vehicle to the first target,
the first image comprises a first mark and a second mark different from the first mark, and
the processor controls the display unit to display the first mark when the vehicle travels toward the first target and display the second mark when the vehicle travels toward the second target.

4. The driving assistance device according to claim 2 , wherein the processor controls the display unit to display the second image in the second form when the vehicle is located within the region and display the second image in the first form when the vehicle is located outside the region.

5. The driving assistance device according to claim 2 , wherein the processor controls the display unit to display the first image or the second image brightly in the first form and display the first image or the second image darkly in the second form.

6. A driving assistance system, comprising:
a processor that
sets a stop target,
acquires a position of a vehicle, and
displays a first image and a second image on a screen, the first image that instructs a driver to stop the vehicle, is displayed in a first form when the vehicle is located within a region including the stop target, and is displayed in a second form different from the first form when the vehicle is located outside the region, the second image indicating a direction corresponding to a travel direction of the vehicle, wherein
the processor disposes the first image with respect to the second image in the direction indicated by the second image, and
the second image is an indicator that points to the first image.

7. The driving assistance device according to claim 1 , wherein
the second image includes a plurality of sections, and
the processor increases or decreases a number of the sections in accordance with a distance between the vehicle and the stop target.
