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 for assisting parking operation to a target parking position comprising:

an initial position setting means 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 means 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 means; and

an initial display position shifting means 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 means is positioned outside of the display range on the screen.

4. A parking assist device according to claim 1, further comprising:

a target parking position setting means;

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.

7. A parking assist device according to claim 1, further comprising:

a parking space frame included in the designation display, the parking space frame configured to be displayed at the initial display position.

8. A parking assist device according to claim 7, wherein

the display position calculation means shifts the parking space frame in accordance with a moving amount of the vehicle upon vehicle movement.

9. A parking assist device according to claim 7, wherein the display position calculation means shifts the parking space frame in accordance with a moving amount of the target parking position when the target parking position is shifted.

10. A parking assist device according to claim 9, wherein a position of the parking space frame configured to be determined based on whether the initial display position of the parking space frame is within the display range of the screen at shifting the target parking position.

11. A parking assist device according to claim 1, wherein the designation display includes a touch display having a touch display portion with plural hierarchical switches.

12. A parking assist device according to claim 11, wherein the designation display includes parking mode switches for executing a parking assist control and switches for designating the target parking position.

2. A parking assist device for assisting parking operation to a target parking position comprising:

an initial position setting means 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 means 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 means; and

a calculated position limiting means for limiting the initial display position calculated by the display position calculation means to be within a display range of the screen.

5. A parking assist device according to claim 2, further comprising:

a target parking position setting means;

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.

3. 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 designation display showing the target parking position;

a display position calculation means for calculating a display position of the designation display showing the target parking position at a screen showing vehicle surroundings 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 before starting to assist the parking operation by confirming the setting of the target parking position.

6. A parking assist device according to claim 3, 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.
