Abstract

A parking support device capable of reliably supporting a parking driving operation by a driver, comprising an image acquisition portion for acquiring an image peripheral to a vehicle captured by a vehicle-mounted image pickup device; an image display portion for displaying the peripheral image; and an indicator output portion for superimposedly displaying an indicator, comprising a pair of left and right vehicle width extension lines extending rearwards of the vehicle, on the peripheral image in order to guide a driver during a parking operation by the driver. The parking support device supports parallel parking, comprising a first turning step, in which the vehicle is reversed while being turned and driven into a parking area, and a second turning step, in which the vehicle is aligned in a parallel direction while being turned in a direction opposite to that in the first turning step. The indicator output portion superimposedly displays, during the second turning step, only the vehicle width extension line that is on an outside of the turn.

Claims

1. A parking support device comprising an image acquisition portion for acquiring an image peripheral to a vehicle captured by a vehicle-mounted image pickup device;

an image display portion, provided within a vehicle chamber, for displaying the peripheral image; and

an indicator output portion for superimposedly displaying an indicator, comprising a pair of left and right vehicle width extension lines extending rearwards of the vehicle, on the peripheral image in order to guide a driver during a parking operation by the driver;

the parking support device supporting parallel parking, comprising a first turning step, in which the vehicle is reversed while being turned and driven into a parking area, and a second turning step, in which the vehicle is aligned in a parallel direction while being turned in a direction opposite to that in the first turning step;

the indicator output portion superimposedly displaying, during the second turning step, only the vehicle width extension line that is on an outside of the turn out of the left and right vehicle width extension lines.

3. The parking support device according to claim 1, wherein the indicator output portion switches between superimposedly displayed indicators based on a steering angle of the vehicle.

5. The parking support device according to claim 1, wherein the indicator output portion does not superimposedly display the vehicle width extension line among the pair of left and right vehicle width extension lines that is on an inside of a turn.

6. The parking support device according to claim 1, wherein the indicator output portion superimposedly displays, in addition to the above-described vehicle width extension line on the outside of the turn, a rear projection line extending in a direction in which the vehicle is projected to travel.

2. A parking support device comprising an image acquisition portion for acquiring an image peripheral to a vehicle captured by a vehicle-mounted image pickup device;

an image display portion, provided within a vehicle chamber, for displaying the peripheral image; and

an indicator output portion for superimposedly displaying an indicator, comprising a vehicle width extension line extending rearwards of the vehicle and a rear projection line extending in a direction in which the vehicle is projected to travel, on the peripheral image in order to guide the driver during a parking operation by the driver;

the parking support device supporting perpendicular parking, comprising a turn-reversing step in which the vehicle is reversed while being turned and is aligned in a perpendicular direction, and a linear reversing step in which the vehicle is reversed in a straight line and driven into a parking area;

the indicator output portion superimposedly displaying only the rear projection line out of the rear projection line and the vehicle width extension line during the turn-reversing step, and superimposedly displaying only the vehicle width extension line out of the rear projection line and the vehicle width extension line during the linear reversing step.

4. The parking support device according to claim 2, wherein the indicator output portion switches between displaying the rear projection line and displaying the vehicle width extension line based on a relative angle between the vehicle and a parking area line demarcating a parking area.
