Abstract

A safety confirmation assist device is equipped with a presenting unit which presents visible information at a position that a driver of a vehicle can recognize it visually, an object detection unit which detects an object approaching the vehicle; and a control unit which controls the presenting unit, if the object detection unit detects the object, to present the visible information moving in a same direction as a left-right component of a direction in which the object is approaching the vehicle while moving the visible information. The control unit controls the presenting unit so that a movement range of the visible information is located on only the left side or the right side, which is the same side of the vehicle as the object is located, of a boundary that defines the left side and the right side for the driver.

Claims

1. A safety confirmation assist device comprising:

an optical displaying device which presents visible information, at a position, visually recognizable to a driver of a vehicle;

an object detector which detects an object approaching the vehicle from a front left side or a front right side;

a control unit which controls the optical displaying device, if the object detector detects the object approaching the vehicle from the front left side or the front right side, to present the visible information moving in the same direction as a left-right component of a direction in which the object approaches the vehicle; and

a line-of-sight detector which detects a line of sight of the driver, wherein;

the control unit controls the optical displaying device so that a movement range of the visible information is located on only a left side or a right side, which is the same side of the vehicle as the object approaching the vehicle from the front left side or the front right side is located, of a boundary that is a plane perpendicular to a road surface, wherein the boundary defines the left side and the right side using, as a reference, the line of sight of the driver detected by the line-of-sight detector, and

the control unit controls the optical displaying device so that distances between the boundary and a starting end where movement of the visible information is started, and a finishing end where the movement is finished, are kept constant, and

wherein when a line-of-sight direction of the driver is changed from a driving direction, the control unit moves the movement range of the visible information according to a movement amount of the line-of-sight direction in such a manner that the movement range does not cross the boundary.

2. The safety confirmation assist device according to claim 1, wherein the optical displaying device projects the visible information onto a windshield of the vehicle.

3. The safety confirmation assist device according to claim 1, wherein the optical displaying device is disposed on inner wall surfaces of a vehicle compartment of the vehicle.

4. The safety confirmation assist device according to claim 1, wherein the optical displaying device is disposed in a whole of a vehicle compartment of the vehicle.
