Abstract

A parking assist device for assisting parking operation to a target parking position includes an initial position setting device for setting an initial position of the target parking position to park a vehicle, a designation display showing the target parking position, a display position calculation device for calculating an initial display position of the designation display showing the target parking position at a screen showing vehicle surroundings based on the initial position determined by the initial position setting device, and an initial display position shifting device for shifting the initial display position of the designation display to a position within a display range on the screen in case the initial display position calculated by the display position calculation device is positioned outside of the display range on the screen.

Claims

1. A parking assist device which starts to assist parking operation after confirming a target parking position comprising:

a target parking position setting means for setting the target parking position to park a vehicle;

a display for displaying a designation display indicating the target parking position at a screen showing vehicle surroundings;

a display position calculation means for calculating a display position of the designation display at a screen based on the target parking position determined by the target parking position setting means; and

a display position movement limiting means for limiting positional movement of the designation display so as not to position the display position calculated by the display position calculation means outside of a display range of the screen upon relative movement between a position of a vehicle and the target parking position determined by the target parking position setting means and judgment that the target parking position is outside of the display range before confirming the setting of the target parking position to start to assist the parking operation.

2. A parking assist device according to claim 1, wherein the display position calculation means calculates the initial display position or the display position based on a vehicle traveling history from the setting of the target parking position by the target parking position setting means or from the setting of the initial position by the initial position setting means.
