Abstract

A driving assistance device includes: an image capturing part configured to image-capture a rear lateral area of a host vehicle and a dead angle area; a display part configured to display a video image captured by the image capturing part; and a blinker switch configured to make a signal of a movement of the host vehicle to a first side or a second side. The display part displays the video image according to a turn on of the blinker switch indicating a movement of the vehicle to the second side, turns off the display of the video image when a predetermined amount of time elapses after the blinker switch is turned off, and turns off the display of the video image before the predetermined amount of time elapses when it is predicted that the host vehicle moves to the first side within the predetermined amount of time.

First claim

The invention claimed is:

1. A driving assistance device comprising:
an image capturing part that is provided, when it is assumed that a driver seat side in a vehicle width direction of a vehicle is a first side and a side opposite to the first side is a second side, on a side mirror on the second side of the vehicle, and is configured to image-capture a rear lateral area of the vehicle and a dead angle area which is adjacent to the rear lateral area outside a visual recognition range of the side mirror on the second side;
a display part configured to display a video image captured by the image capturing part to be visually recognized by a driver of the vehicle; and
a blinker switch configured to make a signal of a movement of the vehicle to the first side or the second side,
wherein the display part displays the video image according to a turn on of the blinker switch indicating a movement of the vehicle to the second side, turns off the display of the video image when a predetermined amount of time elapses after the blinker switch is turned off, and turns off the display of the video image before the predetermined amount of time elapses and displays navigation image data of the vehicle when it is predicted that the vehicle moves to the first side within the predetermined amount of time, and
wherein the display part turns off the display of the video image before the predetermined amount of time elapses when it is predicted that the vehicle moves to the first side within the predetermined amount of time after the blinker switch indicating the movement of the vehicle to the second side is turned off, based on path guide information from a navigation device, the path guide information including route information to a destination or a transit point of the vehicle.

2. The driving assistance device according to claim 1 ,
wherein the display part displays a warning image for performing a warning to a driver when an obstacle is present in the vicinity of the vehicle, and when the video image is displayed on the display part, the warning image, which has a size smaller than a size of the warning image when the video image is not displayed on the display part, is displayed in an overlapping manner with the video image.

3. The driving assistance device according to claim 2 ,
wherein the warning image displayed on the display when the video image is not displayed on the display part is displayed at a position including a central part of a screen on the display part, and the warning image displayed on the display when the video image is displayed on the display part is displayed at a position that overlaps with the vehicle on the video image displayed on the display part.
