Abstract

The vehicle maneuver assistance device includes: a plurality of external environment imaging units; a converter that performs a view point conversion; a display unit provided in an interior of the present-vehicle; a steering angle status value detector which detects status values of the steering angle representing an actual steering angle of the present-vehicle, and outputs a steering angle status value; a display controller that causes the display unit to display the converted image, and, overlaid thereon, a guidance display which assists a parking maneuver of the present-vehicle, wherein the display controller controls the guidance display according to the steering angle status value, so that the guidance display includes: an initial positioning guide line representing an initial location of the present-vehicle at the beginning of the parking maneuver; and a steering-switching start positioning guide line representing a starting location of a quick steering direction switching.

Claims

1. A vehicle maneuver assistance device comprising:

a plurality of imaging units that images an external environment of a present-vehicle, and outputs resulting original images;

a converter that performs a view point conversion on the original images and outputs resulting converted images;

a display unit provided in an interior of the present-vehicle;

a steering angle status value detector which detects status values of the steering angle representing an actual steering angle of the present-vehicle, and outputs a steering angle status value;

a display controller that causes the display unit to display the converted image, and, overlaid thereon, a guidance display which assists a parking maneuver of the present-vehicle, wherein

the display controller controls the guidance display according to the steering angle status value, so that the guidance display includes;

an initial positioning guide line representing an initial location of the present-vehicle at the beginning of the parking maneuver; and

a steering-switching start positioning guide line representing a starting location of a quick steering direction switching.

2. The vehicle maneuver assistance device according to claim 1, wherein:

the display controller controls the guidance display so that, when the parking maneuver is a parallel parking, a parallel parking initial positioning guide line is displayed as the initial positioning guide line; and

the parallel parking initial positioning guide line is arranged so that, when the parallel parking initial positioning guide line is positioned at one of corner parts of a parking frame closest to the present-vehicle, the present-vehicle is positioned at an appropriate parallel parking initial location.

3. The vehicle maneuver assistance device according to claim 1, wherein:

the display controller controls the guidance display so that, when the parking maneuver is a back-in parking, a backup parking initial positioning guide line is displayed as the initial positioning guide line; and

the backup parking initial positioning guide line is arranged so that, when the backup parking initial positioning guide line is positioned at an essentially central position of the parking frame, the present-vehicle is positioned at an appropriate back-in parking initial location.

4. A vehicle maneuver assistance device comprising:

a plurality of imaging units that images an external environment of a present-vehicle, and outputs resulting original images;

a display unit provided in an interior of the present-vehicle;

a steering angle status value detector which detects status values of the steering angle representing an actual steering angle of the present-vehicle, and outputs a steering angle status value;

a display controller that is capable of causing the display unit to display the converted image and, overlaid thereon,

a guidance display which assists a parking maneuver of the present-vehicle, and at least one of

a prediction guidance display representing a driving course of the present-vehicle predicted according to the steering angle status value, and

an indicator guidance display representing a location apart from the present-vehicle by a predetermined distance, wherein

the display controller clears a display of the prediction guidance display and the indicator guidance display, when a predetermined parking maneuver is performed.

5. A vehicle maneuver assistance device comprising:

a plurality of imaging units that images an external environment of a present-vehicle, and outputs resulting images;

a display unit provided in an interior of the present-vehicle; and

a display controller that causes the display unit to display the images and, overlaid thereon, a guidance display which assists a parking maneuver of the present-vehicle, wherein;

the display controller causes the display unit to display a help display including instructions for a maneuver operation during the parking maneuver; and

the display controller causes the display unit to emphasize the display corresponding to a present operation among a plurality of operations included in the maneuver operation.

6. The vehicle maneuver assistance device according to claim 5, wherein the display controller, when emphasizing the display corresponding to the present operation, increases a contrast of the corresponding display.

7. The vehicle maneuver assistance device according to claim 5, wherein the display controller, when emphasizing the display corresponding to the present operation, increases a size of the corresponding display.

8. The vehicle maneuver assistance device according to claim 5, wherein the display controller, when emphasizing the display corresponding to the present operation, changes a color of the corresponding display.

9. The vehicle maneuver assistance device according to claim 5, wherein the display controller arranges the help display at a position not interfering with the guidance display.
